1 00:00:00,000 --> 00:00:21,120 Dean：Today we learn the word curiosity. Curiosity means a strong desire to know or learn something new. It is also the feeling that makes you ask questions. In simpler words, it is “wanting to know more.” Moli, how do you understand this word in Chinese? 2 00:00:21,620 --> 00:00:39,700 茉莉：“curiosity”指的是人对新事物的强烈好奇心，也就是想了解、想知道更多。英文里可以用 “a desire to know” 来对应。它通常作名词，用在日常说话里很常见，比如“保持好奇心”“出于好奇去问”。 3 00:00:40,200 --> 00:00:53,320 Dean：Curiosity is a noun. People use it for the feeling in your mind when you want to learn more. We learn it with examples. Example 1: I looked in the box out of curiosity. 4 00:00:53,820 --> 00:01:17,819 茉莉：这句话的意思是：我出于好奇，把盒子打开看了看。画面是你对某个东西很好奇，所以做了这个动作。这里的 out of curiosity 比较高级一点，意思是“出于好奇心/因为好奇”。你也可以理解为“不是必要原因，是好奇驱动”。Dean, please explain this sentence in simpler English. 5 00:01:18,319 --> 00:01:31,280 Dean：In this sentence, curiosity is the reason for your action. You are not doing it for a rule or a job. Example 2: Her curiosity made her ask many questions. 6 00:01:31,780 --> 00:01:57,700 茉莉：这句话的意思是：她的好奇心让她问了很多问题。场景是课堂或聊天时，她一直想弄明白，所以会不断提问。这里的 made 可以理解为“促使/让结果发生”，但重点仍是 curiosity 让她停不下来。Dean, please continue with a simpler explanation in English, then give example 3. 7 00:01:58,200 --> 00:02:11,000 Dean：Her curiosity means she really wanted to know more. That is why she asked many questions. Example 3: Kids have curiosity about everything. 8 00:02:11,500 --> 00:02:33,099 茉莉：这句话的意思是：孩子们对每件事都有好奇心。场景很生活化，比如孩子会对玩具、动物、天气一直追问。“have curiosity about”表示“对……有好奇心”，用来描述一种常见的心理状态。接下来，我们讲词根词缀与词源。 9 00:02:33,599 --> 00:02:44,319 Dean：Let’s talk roots, affixes, and the word’s origin for curiosity. What parts can we recognize, and what do they suggest about the meaning? 10 00:02:44,819 --> 00:03:40,019 茉莉：我们先把 curiosity 这个词“拆开想一下”。它听起来像是由两个意思拼起来的：一个跟“想要/渴望”有关的感觉，另一个跟“去看、去了解”有关。英语里很多词会用拉丁语和法语的根来做“拼图”，最后变成现在这种看上去挺整齐的单词。你可以把它想成：人脑里有一种想去看清、想弄明白的冲动，所以才会有强烈的 curiosity。顺便说到“同族词”，curious 你一定见过，它基本上是形容词，意思更偏“好奇的”；而 curiosity 更像是“这种状态/这种心情本身”。还有一个大家常听到的词 curiosity 的亲戚词是 inquire，虽然拼法不同，但都和“问、探求信息”那种动作很像，所以它们常常出现在同一种思维链里：先想知道，再去问。现在我们再讲它的身世会更有画面感一点。 11 00:03:40,519 --> 00:03:46,599 Dean：Nice. So where did it come from, and how did its meaning change as time went on? 12 00:03:47,099 --> 00:04:47,100 茉莉：这个故事要从更早的语言里说起。很久以前，人们用一些拉丁语的词根来表达“用意图去探寻、去追问”，当它们慢慢传到法语、再进入英语，就逐渐变成“想知道某件事”的那种心理倾向。早期不一定就完全是今天这种“强烈的求知欲”，它更像是一种主动的探求心。后来随着用法变多，人们会更常说“out of curiosity”“satisfy your curiosity”，也就是把这种心情当成一个稳定的名词来谈。于是 curiosity 就变得更具体：不是某一次的问话，而是你心里一直存在的那股想弄明白的力量。对我来说，最有趣的是它从“想探寻”的动作，慢慢变成了我们今天说的“一个可以被满足、被保持的心情”，好像心里真的住着一个小小的探险家。下一部分我们就来讲搭配、常见场景和怎么在互动里自然用出来。 13 00:04:47,600 --> 00:05:04,720 Dean：Imagine you are in a small shop, and you see a new gadget on the shelf. You do not need it, but you want to know how it works. You ask the shop worker a few questions. In this situation, what collocation can we use with curiosity? 14 00:05:05,220 --> 00:05:22,020 茉莉：第一个搭配我们用 out of curiosity。它表示“出于好奇”，重点是你这样做不是因为必须，也不是因为有任务，而是因为心里想弄明白。语气更像“我只是好奇，所以问一下/看看”。 15 00:05:22,520 --> 00:05:26,840 Dean：Right. Out of curiosity, I read the whole product page. 16 00:05:27,340 --> 00:05:40,300 茉莉：这句很自然。out of curiosity 让理由听起来更轻松，也更像生活场景里的真实反应。你读页面不是工作要求，而是被好奇心带着走。 17 00:05:40,800 --> 00:05:56,319 Dean：Now think about school. Your teacher gives a group task, and you need information for your project. You start searching online and taking notes, because you really want to understand the topic better. In this situation, how do people use curiosity? 18 00:05:56,819 --> 00:06:15,219 茉莉：第二个搭配是 satisfy your curiosity。意思是“满足你的好奇心”。当你通过阅读、提问、查资料得到答案，就可以说满足了好奇心。它的语感是：好奇到最后，终于得到明确的结果。 19 00:06:15,719 --> 00:06:20,199 Dean：I watched the video to satisfy my curiosity. 20 00:06:20,699 --> 00:06:31,899 茉莉：这里的选择很贴切。to satisfy my curiosity 用在你终于弄懂一件事的时候很常见，也能让听者一下明白你为什么要去看视频。 21 00:06:32,399 --> 00:06:49,839 Dean：Next, let’s move to everyday social life. You hear a rumor in your friend group. Someone says, “You know what, I can tell you a secret.” You feel interested and you want more details, but you also try to be polite. What collocation fits this moment? 22 00:06:50,339 --> 00:07:09,219 茉莉：第三个搭配是 arouse curiosity。意思是“引起好奇心”。它更像描述一种效果：某个消息、一个问题、一个标题让别人变得想知道更多。比起 out of curiosity 更强调“别人被你的内容点燃了”。 23 00:07:09,719 --> 00:07:13,559 Dean：That headline really aroused my curiosity. 24 00:07:14,059 --> 00:07:26,059 茉莉：这句很地道。arouse curiosity 常用来讲“信息/行为带来的结果”，比如新闻标题、神秘线索、开场问题等，都可以用它来表达。 25 00:07:26,559 --> 00:07:46,399 Dean：Last scene. You join a museum tour. The guide shows a short demo, and you feel excited to ask questions. The tour is interesting, and you want to keep learning step by step. Which is more natural: “curiosity made me ask” or “curiosity satisfied me”? Choose one, and make a short sentence. 26 00:07:46,899 --> 00:08:10,419 茉莉：互动题：选哪一个更自然，并造一句话。答题要点是区分动词和结果方向：made me ask 表示好奇心促使你去问；satisfied me 表示你因为知道了内容而觉得好奇心被满足。接下来你可以先说出你选择的表达，再用一句简单的话把场景串起来。 27 00:08:10,919 --> 00:08:16,679 Dean：What are some common synonyms of this word? How are they different in usage? 28 00:08:17,179 --> 00:08:37,979 茉莉：curiosity 的常见近义词可以说 4 个左右：interest，inquiry，wonder，questioning。它们的细微差别主要在“想知道的感觉”和“把它变成行动”的程度，以及更正式还是更日常。我们一个一个来对比，先看第一个。 29 00:08:38,479 --> 00:08:43,279 Dean：OK, what is the first synonym? How should I use it correctly? 30 00:08:43,779 --> 00:09:14,339 茉莉：interest。interest 通常更偏“感兴趣的状态”，不一定强调强烈的想弄明白。curiosity 更像“很想知道更多，所以会追问”。在日常说法里，interest 更自然，用于爱好、主题、话题；而 curiosity 更常用在“你看到/听到某事后想深入了解”的语境里。例句：I have an interest in space, but I do not ask many questions. 31 00:09:14,839 --> 00:09:18,679 Dean：Confirm that. What about the next synonym? How is it different? 32 00:09:19,179 --> 00:09:45,899 茉莉：inquiry。inquiry 更正式一点，也更偏“调查或询问的过程”，常用于工作、研究或官方场合。curiosity 更偏个人心理驱动，语气更轻松、更日常。inquiry 的搭配里，你常见它和 ask / make / carry out 一类的用法一起出现。例句：The report led to an official inquiry into the problem. 33 00:09:46,399 --> 00:09:48,959 Dean：What about the third synonym? 34 00:09:49,459 --> 00:10:12,979 茉莉：wonder。wonder 更像“惊奇 + 想弄清楚”的感觉，语气往往带一点“哇，为什么会这样？”更偏情绪，不一定直接等同于 curiosity 的“持续追问”。curiosity 更中性，强调想知道更多；wonder 更偏对某件事的感觉很强烈。例句：I wonder why the device works so well. 35 00:10:13,479 --> 00:10:17,319 Dean：What about the fourth synonym? 36 00:10:17,819 --> 00:10:41,979 茉莉：questioning。questioning 更像“反复提问的行为或态度”，有时甚至带一点怀疑或审问的意味。curiosity 不等于怀疑，它更像求知和探索。questioning 常见于讨论、学习过程，或需要你“提出很多问题”的场景。例句：There was a lot of questioning during the meeting. 37 00:10:42,479 --> 00:10:45,839 Dean：Can you summarize when to use which word? 38 00:10:46,339 --> 00:11:18,819 茉莉：总结一下：如果你想表达“对某个话题感兴趣”，用 interest；如果是更正式的“调查/询问过程”，用 inquiry；如果你是“带惊讶的想弄明白”，用 wonder；如果你想强调“不断提问的行为或态度”，用 questioning。你在日常聊天里，大多数情况下直接用 curiosity 会最贴切，因为它既能表达心理动机，也能自然引出提问。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:11:19,319 --> 00:11:27,799 Dean：We have learned so much. Now let’s relax with a fun short story related to curiosity. 40 00:11:28,299 --> 00:11:30,539 茉莉：什么故事？我想听！ 41 00:11:31,039 --> 00:12:05,919 Dean：Last week, I was at my office. My manager brought a new coffee machine. It looked fancy, but it also looked dangerous. I said, “I just want to understand it.” So I looked closely out of curiosity. The machine had one big button. It said “START,” but the button was under a small cover. So I asked the IT guy, “What happens if I press it?” He smiled and said, “It will make coffee. But please do not test it too early.” 42 00:12:06,419 --> 00:12:12,659 茉莉：然后呢？你真的就按下去了，还是忍住了？这也太想知道了！ 43 00:12:13,159 --> 00:12:51,719 Dean：I waited… for exactly five seconds. Then I pushed the button out of curiosity again, because my coworker said, “Maybe it needs a password.” At that moment, the machine started with a loud sound. It did not make coffee. It printed a small paper note. The note said, “TO SATISFY YOUR CURIOSITY: PLEASE READ THE MANUAL.” Everyone laughed. Even the manager laughed. My coworker said, “Your curiosity aroused the machine’s curiosity too.” 44 00:12:52,219 --> 00:13:16,699 茉莉：哈哈！所以机器也在“引导你学习”。我懂了：你用 out of curiosity 表示你只是好奇；然后你用 to satisfy your curiosity 来表示最后想弄清楚的结果。还有 arouse curiosity 是“把别人（或某个东西的反应）点起来”的感觉。这个故事太真实了！ 45 00:13:17,199 --> 00:13:39,279 Dean：Yes, and now you know how to use curiosity in real life. Remember: you can act out of curiosity, and you can try to satisfy your curiosity. And sometimes, curiosity can even create a funny situation at work. Thanks for listening. Keep your curiosity, and I’ll see you next time!

1 00:00:00,000 --> 00:00:17,600 Dean：Today we learn the word “trifle.” “Trifle” means something very small and not important. It can also mean a sweet dessert with cream and fruit. A trifle is “something small” or a “small dessert.” Moli, how do you understand this word in Chinese? 2 00:00:18,100 --> 00:00:34,740 茉莉：“trifle” 主要有两种意思：第一是指“小事、微不足道的事”；第二是指“一种甜点，通常是奶油和水果分层的点心”。英文对应可以说 small thing. 这个词是什么词性？常怎么用？ 3 00:00:35,240 --> 00:00:51,240 Dean：Trifle is a noun. We use it for a small, not serious matter. We can also use it to mean a layered dessert. Next, let’s learn with examples. Example 1: “He said it was a trifle mistake, so we did it again.” 4 00:00:51,740 --> 00:01:09,980 茉莉：这句话的意思是：他觉得那是个小错误，不算严重，所以他们又做了一次。句子里 “trifle” 表示“小事、微不足道的错误”。这个用法里它通常表示不重要，不用在很大的问题上。Dean, can you explain this sentence in simpler English? 5 00:01:10,480 --> 00:01:25,840 Dean：In this sentence, “trifle” sounds like the person feels the mistake is not serious. We use it to downplay a small problem. Example 2: “I don’t care about that trifle; let’s focus on the main task.” 6 00:01:26,340 --> 00:01:42,820 茉莉：这句话的意思是：那点小事我不在乎，我们把注意力放在主要任务上。这里的 “trifle” 也是“小事”，语气会有点不想讨论细节的感觉。它常用在日常说话里。请你继续用更简单的话讲清语感，Dean。 7 00:01:43,320 --> 00:01:58,040 Dean：Here, “trifle” means “a tiny, unimportant issue.” The speaker wants to stop talking about it and move on. Example 3: “For dessert, we had a trifle with strawberries and cream.” 8 00:01:58,540 --> 00:02:12,140 茉莉：这句话的意思是：作为甜点，他们吃了草莓和奶油做的分层甜点。这里的 “trifle” 是第二种意思，指一种甜点。接下来，我们讲词根词缀与词源。 9 00:02:12,640 --> 00:02:23,200 Dean：What are the word roots, affixes, and the history of the word “trifle” in a simple way? Where did the pieces come from, and what did they originally mean? 10 00:02:23,700 --> 00:03:30,740 茉莉：我们先把它当成一个“拼装出来的词”。trifle 这个家族，其实在拼写和读音上和另一些老词有点像。它和动词 trifle 有关系，那个动词过去常有“玩一玩、随便对待、不要太认真”的味道。你可以想象中世纪早期的人在说 “don’t trifle with it” 的时候，意思不是“别碰一下”，而是“别拿它当小玩意儿、别敷衍”。而名词 trifle 就慢慢变得更具体：既可以是“小事”，也可以是“一点点不重要的小甜点”。所以它的意思从“随便玩、心思不重”一路走到“很小、没那么重要”。 同族词方面，你会看到它和 trifle 这个动词、以及一些表示“轻视、敷衍”的用法有共通的气质。比如当你说 someone is trifling, 不是夸他认真，而是在说他态度轻浮、把事情处理得很不当回事。另一个亲戚词在意思上也很近：trivial 也有“不重要、很小”的意思，只是 trivial 更像从“琐碎”的角度去说，而 trifle 更常带一点“轻轻松松但不够严肃”的语感。 11 00:03:31,240 --> 00:03:42,120 Dean：So what did “trifle” originally mean? How did it change over time to become both “something small and not important” and also a kind of dessert? 12 00:03:42,620 --> 00:04:54,300 茉莉：就像一条小线索慢慢延伸出来的故事。最早这类词来自更古老的法语或拉丁语相关表达，核心思想大概是“轻轻地做、带点敷衍的态度”，有点像你把一件事当成玩笑，没打算认真解决。后来人们在日常交流里常用它来描述那种“没放在心上”的事情，于是意思就逐步变成 “小事、不重要”。当你再进一步把“轻视”和“随便弄点东西”联系起来，尤其是饮食场景里，人们也会用类似的词说某种“看起来精致但分量不大”的甜点，于是 trifle 就发展出了第二层意思：一种分层的甜点，通常有奶油和水果，份量不一定大，但味道很讲究。 我觉得最有趣的是它的情绪变化：从“不要玩不要敷衍”这种态度，到后来真的变成了“甜点里的小块小层”，同一个词，最后竟然能在餐桌上变得温柔。下一部分我们会讲它常见的搭配、在什么场景里更自然，以及大家会怎么互动来用它。 13 00:04:54,800 --> 00:05:10,480 Dean：Imagine you are waiting for a friend. You text them, “Are you coming?” They reply, “Sorry, I had a trifle problem. My phone battery died.” In this situation, how do we use “trifle” naturally? 14 00:05:10,980 --> 00:05:35,140 茉莉：第一个搭配：a trifle problem。这个表达的感觉是“一个小问题，但不想把事情闹得很大”。trifle 在这里带着轻描淡写的语气，听起来就像“没什么大不了的”，让对方别担心。这里的 problem 只是补足语义，让听起来更具体，但核心还是“小而不严重”。 15 00:05:35,640 --> 00:05:42,680 Dean：Right. Here is a short example: “I was late, but it was a trifle problem, not a big emergency.” 16 00:05:43,180 --> 00:05:58,220 茉莉：在这种日常场景里讲 a trifle problem 很自然，尤其是对方如果急着等你、或你需要解释延误时。你用它，就等于在安抚对方：事情不算严重，别紧张。 17 00:05:58,720 --> 00:06:10,560 Dean：Now think about school. You make a small mistake in class, and your teacher says, “Don’t worry. It’s a trifle.” In this kind of situation, how should we use the word? 18 00:06:11,060 --> 00:06:35,060 茉莉：第二个搭配：it’s a trifle。这个结构特别常用，语气像是在安慰或缓和气氛。它表示“没关系，真的不重要”。在课堂或小争执里，说 it’s a trifle 会显得老师或同学更宽容，不会把小问题升级成大矛盾。注意它比 “not important” 更口语、更带情绪安抚。 19 00:06:35,560 --> 00:06:41,800 Dean：Sure. Example: “It’s a trifle. Let’s fix it and move on.” 20 00:06:42,300 --> 00:06:54,460 茉莉：这个用法非常适合老师或同学在轻轻带过问题的时候。像 move on 这种表达经常搭配出现，整体就是“先别纠结，继续做正事”。 21 00:06:54,960 --> 00:07:07,280 Dean：Third scene: you go to a party. Someone drops a glass and says, “Oh no, a trifle.” But everyone can see it’s messy. What collocation fits this moment? 22 00:07:07,780 --> 00:07:29,060 茉莉：第三个搭配：a trifle too much。它的语感是“有点过了，不是大错，但确实不太合适”。在聚会这种场景里，如果有人把玩笑或细节做得有点夸张，就可以用这个。它有轻微的评价意味，不是单纯说“小”，而是提示“力度或分寸不太对”。 23 00:07:29,560 --> 00:07:34,360 Dean：Example sentence: “I think that joke was a trifle too much for this group.” 24 00:07:34,860 --> 00:07:50,700 茉莉：对，这里就能看出“trifle”从“小”变成了“小题大做之外的那种偏差”。它不像 a trifle problem 那么中性，也不像 it’s a trifle 那么安慰，而是更像“差一点就更好”。 25 00:07:51,200 --> 00:08:08,000 Dean：Last, quick interaction. I will give you two choices. Choose the more natural one for each sentence in a party or café setting. First: “Sorry, it’s a trifle ___.” A) too much B) problem. Which one is better, and why? 26 00:08:08,500 --> 00:08:40,020 茉莉：好，我们来互动。题目是：在聚会或咖啡店这种场景里，“Sorry, it’s a trifle ___.” 你要选更自然的填空。要点是看句子的语气：如果是在道歉并说明原因，通常更像 a trifle problem；如果是在表达“有点过了”，更像 a trifle too much。你在回答时，先选 A 或 B，再用一句话说清楚理由。接下来我还想了解：你觉得这几个搭配和 “trivial” 的感觉有什么不同吗？ 27 00:08:40,520 --> 00:08:46,600 Dean：What are some common synonyms of “trifle”? How are they different in usage? 28 00:08:47,100 --> 00:08:57,020 茉莉：“trifle” 常见近义词有：trivial、minor、small matter、petty、light. 我们一个一个来对比，先看第一个。 29 00:08:57,520 --> 00:09:03,280 Dean：OK. What is the first synonym? How should I use it correctly? 30 00:09:03,780 --> 00:09:40,260 茉莉：第一个近义词是 trivial。含义差别是 trivial 更强调“琐碎、没多大意义”，通常不太用来强调“轻描淡写的态度”，而是更像在评价事情本身很小很不重要。适用场景：写作和日常都能用，但更常见于“事情不值得认真对待”。语气和正式程度：比 trifle 更中性一点，也稍微更偏书面。简短例句：It was a trivial mistake, so nobody got angry. 这句里 trivial 表示“错很小，值得不值得生气都不大”。 31 00:09:40,760 --> 00:09:45,240 Dean：Got it. What about the next synonym? How is it different? 32 00:09:45,740 --> 00:10:19,980 茉莉：第二个近义词是 minor。含义差别是 minor 强调“影响不大、程度较低”，更接近“没那么严重”。适用场景：更适合谈问题、故障、错误的严重程度，尤其当你需要表示“不是大问题”。语气和正式程度：很中性，略偏正式或更“理性描述”。搭配上更常见和 issue、problem、damage、injury 等词连用。简短例句：The delay was minor, and we still started on time. 33 00:10:20,480 --> 00:10:24,480 Dean：Thanks. Ask me about the third synonym. 34 00:10:24,980 --> 00:10:53,780 茉莉：第三个近义词是 small matter。含义差别是 small matter 更像口语里对对方的安慰，强调“这事不需要担心”。适用场景：更常用于解释误会、轻微麻烦，或让别人别紧张。语气和正式程度：很口语，也更有人情味。搭配上经常直接用 “It’s a small matter.” 或 “It’s just a small matter.” 简短例句：Don’t worry, it’s a small matter. I can fix it quickly. 35 00:10:54,280 --> 00:10:58,120 Dean：OK. What about the next one, if there is another synonym? 36 00:10:58,620 --> 00:11:30,620 茉莉：还有一个近义词是 petty。含义差别是 petty 更偏负面，指“鸡毛蒜皮但让人不舒服”，或者“格局小、爱计较”。适用场景：常用来形容人或行为，比如不必要的争吵、爱挑小毛病。语气和正式程度：带评价，语气更强，通常比 trifle 更有批评感，也更适合在抱怨或讨论态度时用。简短例句：He made a petty comment, and it ruined the mood. 37 00:11:31,120 --> 00:11:36,880 Dean：Last question: can you summarize when to use which word? 38 00:11:37,380 --> 00:12:06,500 茉莉：总结一下：如果你想表达“非常小、也不太值得认真”的一般感觉，用 trivial 更像在说“琐碎不重要”；如果你强调“问题不严重”，用 minor 更准确；如果你想安慰别人“别担心，这只是小事”，用 small matter 更自然；如果你想带一点批评，说“看起来小但很让人反感”，用 petty。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:12:07,000 --> 00:12:15,000 Dean：We have learned so much about “trifle.” Now let’s relax with a fun short story. 40 00:12:15,500 --> 00:12:18,540 茉莉：什么故事？快说呀，Dean！ 41 00:12:19,040 --> 00:12:30,880 Dean：So, yesterday at work, I was in a meeting room. I brought coffee for everyone. Then I noticed one cup had no lid. I said, “Sorry, it’s a trifle problem.” Everyone laughed. 42 00:12:31,380 --> 00:12:38,580 茉莉：听起来你在认真道歉，但又故意说得很轻松。后来呢？他们相信你没事了吗？ 43 00:12:39,080 --> 00:12:52,840 Dean：Yes. Then my manager walked in. He saw the open coffee and said, “Don’t worry. It’s a trifle.” But one minute later, my sleeve touched the cup. Coffee spilled a little on my notebook. 44 00:12:53,340 --> 00:13:00,380 茉莉：哇！那你就尴尬了。你接下来怎么说，Dean？你还会用 trifle 吗？ 45 00:13:00,880 --> 00:13:22,320 Dean：I tried to stay calm. I told him, “It’s a trifle. And also… it’s not a big emergency.” Then I picked up my notebook and added, “But please do not call it a trifle dessert.” 46 00:13:22,820 --> 00:13:38,660 茉莉：哈哈哈！因为那杯咖啡真的不是甜点，对吧。这个故事里，“trifle problem” 用来解释原因、让事情显得不严重；“It’s a trifle” 用来安慰大家；最后你还玩了 “trifle dessert” 的对比，让笑点更轻松。 47 00:13:39,160 --> 00:13:53,240 Dean：Now you remember: “trifle” can mean a small, not serious issue. And it can also be a small dessert. Thanks for listening, and see you next time—have a great day, and don’t stress over trifles!

1 00:00:00,000 --> 00:00:23,039 Dean：Today we learn the word relativity. Relativity is the idea that space and time can change for different people. It can also mean fairness to different situations. In simpler words, it is how time and space may feel different. Moli, how do you understand this word in Chinese? 2 00:00:23,539 --> 00:00:41,619 茉莉：relativity 是“相对性”的意思：同一件事在不同条件下，感觉和结果可能不一样；中文常说“相对、因人因条件而变”。简短英文对应：the truth depends on conditions. 这是什么词性，常怎么用？ 3 00:00:42,119 --> 00:01:04,199 Dean：Relativity is a noun. We often use it in science, especially about Einstein’s ideas of space and time. We use it to talk about how measurements can be different. We use examples to learn. Sentence 1: In Einstein’s relativity, time can pass at different speeds for different observers. 4 00:01:04,699 --> 00:01:23,899 茉莉：例句的意思是：在爱因斯坦的相对论里，不同的人或观察者测到的时间流逝速度可能不同。这里的 observers 指的是“观察者、看的人”。relativity 在这句话里是一个非常偏科学的概念。你能用更简单的英文再解释这句吗？ 5 00:01:24,399 --> 00:01:42,000 Dean：Sure. It means two people may not agree on the same time, depending on their situation. It is a science idea about space and time. Sentence 2: GPS uses relativity to work well, because satellites and clocks are not the same. 6 00:01:42,500 --> 00:02:01,060 茉莉：这句话的场景是：我们用 GPS 导航，它需要考虑相对论带来的影响，不然定位就会不准。这里的 clocks 是“时钟、计时设备”；satellites 是“卫星”。relativity 指的就是相关的科学原理。请继续，用更简单的英文解释语感。 7 00:02:01,560 --> 00:02:18,199 Dean：Right. GPS needs small science corrections so the time stays correct. If we ignore it, results can be wrong. Sentence 3: Even on Earth, people talk about relativity when they say “it depends” on the situation. 8 00:02:18,699 --> 00:02:37,899 茉莉：这句是在用“相对性”做日常类比：当人们说“这要看情况”，就像在表达“不同条件会带来不同结果”。这里的 “it depends” 是在表达因条件而异，不是指真正的科学公式。接下来我们讲词根词缀与词源。 9 00:02:38,399 --> 00:02:46,719 Dean：What are the word roots, affixes, and the etymology of relativity? Can you break it down in a simple way? 10 00:02:47,219 --> 00:04:08,819 茉莉：好，我们把 relativity 想成“关系”在时间和空间里的延伸。它看起来像从 relate 走来的。relate 这个词本身就有“把事情联系起来、讲出关系”的感觉。relativity 的名词形式，就是把这种“关系、关联”的意思扩展成一个更抽象的概念。你会看到它常和 -ity 这种名词后缀一起出现，这个后缀会把形容或抽象的感觉变成“某种状态、某种概念”。所以 relativity 可以理解成“关系性，或者说和条件相关的那种性质”。另外，亲戚词也很有趣：比如 relate 和 relation 都是同一条家族线上的词，只是 relate 更像“讲关系、建立联系”，relation 更像“关系这个名词”，而 relativity 则更进一步，变成了“时间和空间会因条件而变化”的科学观念。 至于词源演化，它原来来自拉丁语的相关词根，意思大概是在“把东西联系起来、讲清楚它们之间的关系”。后来在英语里，它逐渐从“关系是什么”变成“关系会影响判断”。当你走到现代科学语言，尤其爱因斯坦的思想里，“相对”不再只是日常理解，而是成了一个正式理论：不同观察者在不同条件下，会得到不同的时间和空间体验。最后，这个词就在科学和日常表达之间找到自己的位置。 11 00:04:09,319 --> 00:04:15,239 Dean：So what did relativity originally mean, and how did the meaning change over time? 12 00:04:15,739 --> 00:05:20,859 茉莉：就像一个故事从街头走进了实验室。最早的意思更偏向“关联、把事讲到一起”，你可以把它想成在说：事情之间不是孤立的，它们有关联。后来人们用它去表达“判断会受条件影响”，也就是我们今天说的“因人因条件而不同”。当它进入科学讨论时，语言就变得更精准了：爱因斯坦用它来讲空间和时间不是固定不变的舞台，而是会随着观察者的状态而呈现出不同结果，于是 relativity 变成了一个非常明确的理论名字。此时它和 relation 的距离变远了一点：relation 说的是“关系”，relativity 说的是“关系导致的变化方式”。我觉得最有趣的是，它明明从“联系”这种很普通的感觉出发，最后却变成了改变我们理解时间和空间的关键词。下一部分我们可以聊搭配、常见场景和互动方式，让你在真实对话里用得更自然。 13 00:05:21,359 --> 00:05:37,839 Dean：Imagine you are watching a school science video about time and space. Then the teacher says, “Relativity depends on the observer.” You feel confused and you ask: in this situation, how do we use this word? 14 00:05:38,339 --> 00:06:10,659 茉莉：第 1 个超实用搭配是 relate it to the observer：也就是把相对性“和观察者联系起来”。更自然的英文说法是 in terms of the observer 或 depending on the observer。这里的 observer 指“看的人、测量的人”。语感上，就是在强调不同的人在不同位置或条件下，会得到不同结果。你不要把它理解成“这只是观点”，而是强调“测量会随观察者改变”。 15 00:06:11,159 --> 00:06:21,559 Dean：In simple words, it means the result changes with the observer. Example: “In relativity, time can change depending on the observer.” 16 00:06:22,059 --> 00:06:46,859 茉莉：这句话里时间会“随观察者变化”，就是 in relativity 的核心语感。above B1 的部分不用太担心：depending on 的意思就是“取决于、由……决定”，observer 就是“观察者/测量者”。整句在口语里很常用，适合你听不懂原理时先抓“看的人不同，结果可能不同”。 17 00:06:47,359 --> 00:06:59,039 Dean：Now think about a job meeting. Your manager shows a map and says, “For good GPS results, we must use relativity.” If your friend asks, “Why?” what would you say? 18 00:06:59,539 --> 00:07:24,339 茉莉：第 2 个搭配是 use relativity in order to 或 use relativity for + 目的。它常出现在工程、科技、新闻解释里，用来说明“为了让结果更准确，我们要用相对论相关的原理”。在语感上，它强调的是原因和目的：不是在讲故事，而是在讲“必须做的调整”。 19 00:07:24,839 --> 00:07:32,519 Dean：It means “we do it for accuracy.” Example: “GPS uses relativity for accurate location.” 20 00:07:33,019 --> 00:07:48,859 茉莉：这里的 accurate 是“准确的”，location 是“位置”。你在表达场景时可以把它理解为：为了让定位更准，我们要用 relativity 做修正。这个搭配很像新闻或工作里的“原因句型”。 21 00:07:49,359 --> 00:08:06,799 Dean：Last scene: you read a short news post online. It says, “Some people feel different time during stress.” Then it also mentions relativity in a simple way. In daily talks like this, how do we use the word? 22 00:08:07,299 --> 00:08:30,979 茉莉：第 3 个搭配是 relate relativity to everyday life 或 use relativity as an analogy for daily situations。也就是“用相对性来类比日常体验”。它的语感是：不是在讲严格科学公式，而是借用一个科学词，帮助大家理解“因条件而不同”。 23 00:08:31,479 --> 00:08:39,159 Dean：A simple example sentence: “People use relativity as an analogy for how time feels different.” 24 00:08:39,659 --> 00:08:57,899 茉莉：这里 as an analogy for 就是“作为类比来说明”。analogy 的意思是“类比、用相似情况帮助理解”。你在日常聊天里用这个搭配，就不会显得太学术，也更贴近你听到的那种新闻表达。 25 00:08:58,399 --> 00:09:21,600 Dean：Now, for a 4th one, imagine you are in a classroom. The teacher says: “Relativity is part of science.” Which expression sounds more natural? A) “Relativity is part of science.” B) “Relativity is in part of science.” Choose A or B, and make one short sentence with your choice. 26 00:09:22,100 --> 00:09:44,820 茉莉：互动题：选 A 或 B，并用你选的那句造一个短句。答题要点是记住 part of 表示“……的一部分”，而 in part of 不符合这个搭配习惯。接下来我还想了解：你觉得 relativity 和 relation 的区别是什么？你可以用中文说要点，然后我们一起用更自然的英文再写一遍。 27 00:09:45,320 --> 00:09:51,400 Dean：What are some common synonyms of this word? How are they different in usage? 28 00:09:51,900 --> 00:10:28,860 茉莉：relativity 的近义词在英语里通常不是完全“一对一”的同义词，而是更接近的概念词。常见的有 4 个： 1）relatedness：更偏“关联性”，强调事物之间有关系。 2）interdependence：更偏“相互依赖”，强调互相影响、互相需要。 3）conditionality：更偏“条件性”，强调结果取决于条件。 4）variance：更偏“差异/变化”，强调量或结果的不同。 我们一个一个来对比，先看第一个。 29 00:10:29,360 --> 00:10:35,280 Dean：OK, what is the first synonym? How should I use it correctly? 30 00:10:35,780 --> 00:11:23,940 茉莉：relatedness。含义上，relativity 更像“空间和时间会随条件、观察者而变”的理论或概念；relatedness 更直接表达“关联性”，不强调时间和空间的变化规律。 适用场景上，relatedness 常用于日常或研究里说“概念之间的联系”，而不是讲爱因斯坦那种科学理论。 语气上，relatedness 更中性、更常见于非正式说明或一般学术写作，不像 relativity 那样带有强烈的科技术名感。 搭配上，你会更常看到 relatedness between ideas 或 relatedness of things。 例句：There is a strong relatedness between two ideas in this chapter. 31 00:11:24,440 --> 00:11:28,280 Dean：Got it. What about the next synonym? How is it different? 32 00:11:28,780 --> 00:12:14,700 茉莉：interdependence。relativity 强调“取决于观察者或条件”；interdependence 强调“双方彼此依赖、互相影响”。所以它更像在说因果和依赖关系，而不只是“会不会变化”。 适用场景上，interdependence 常用在经济、团队、系统、生态等主题，讲“各部分互相影响”。relativity 则主要出现在科学语境，尤其是时间和空间的讨论。 语气上，interdependence 通常更正式、更偏分析性。 搭配上，interdependence between people 或 interdependence of parts 很常见。 例句：Our work shows interdependence between teams, not just separate tasks. 33 00:12:15,200 --> 00:12:18,879 Dean：Thanks. What about the third synonym? 34 00:12:19,379 --> 00:13:09,299 茉莉：conditionality。relativity 的核心是“不同条件下会有不同结果”；conditionality 更像在强调“基于条件才能成立”的规则或性质。它更像表达规则结构，而不是一个完整的科学理论名称。 适用场景上，conditionality 常用于政策、合同、规则、学习目标等，讲“有条件才可以/才生效”。在科学讨论里，它不会像 relativity 那样直接指向空间与时间的观念。 语气上，conditionality 更正式，常见于说明、制度或写作。 搭配上，conditionality on a condition 或 economic conditionality 这类搭配很常见。 例句：The offer depends on conditionality in the contract. 35 00:13:09,799 --> 00:13:15,559 Dean：OK. If there are any more, tell me the third one, then ask about the last. 36 00:13:16,059 --> 00:13:55,579 茉莉：variance。含义上，relativity 强调“概念会随条件与观察者呈现不同样子”；variance 更强调“差异”和“波动”，可以是数字、结果或表现的变化，但不一定带有“观察者视角”的意思。 适用场景上，variance 常用于统计、数据分析，或一般描述“结果不一致”。relativity 更偏科学概念，尤其与时间和空间测量相关。 语气上，variance 更偏学术或技术语感。 搭配上，你会更常看到 variance in results 或 high variance。 例句：The test results show high variance across classes. 37 00:13:56,079 --> 00:14:00,079 Dean：Can you summarize when to use which word? 38 00:14:00,579 --> 00:14:38,659 茉莉：总结一下： - 想说“关联性”，但不强调时间和观察者，就用 relatedness。 - 想说“彼此依赖、互相影响”，常用 interdependence。 - 想强调“结果取决于条件/有条件才生效”，用 conditionality。 - 想表达“差异或波动”，尤其数据或结果不一致，用 variance。 如果你是在讲爱因斯坦的空间和时间概念，最稳妥的还是直接用 relativity，因为它是一个非常特定的科学用法。 最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:14:39,159 --> 00:14:47,639 Dean：We have learned so much. Now let's relax with a fun short story related to relativity. 40 00:14:48,139 --> 00:14:49,580 茉莉：什么故事？ 41 00:14:50,080 --> 00:15:16,160 Dean：Last Friday, I was in a school computer lab. My teacher said, “For the best GPS demo, remember relativity.” Then my friend Sam put his phone on the desk and laughed. He said, “My phone is fine. It does not need science.” I answered, “GPS uses relativity for accurate location, so it can update your time and place.” 42 00:15:16,660 --> 00:15:20,500 茉莉：然后呢？他是不是当场就翻车了？ 43 00:15:21,000 --> 00:15:51,400 Dean：Yes! The teacher asked us to walk to Room 201. Sam started fast. But when he arrived, he looked shocked. He said, “The map shows Room 201… but it is wrong!” I checked my phone and said, “Maybe your phone clocks are different. In relativity, time can change depending on the observer.” Sam replied, “Observer? I am the only observer. So the problem is me. Great.” 44 00:15:51,900 --> 00:16:00,540 茉莉：哈哈！所以他把科学问题当成自我评价了。总结一下，这个故事里我们怎么用 relativity？ 45 00:16:01,040 --> 00:16:30,160 Dean：We used relativity in real life in two ways. First, “GPS uses relativity for accurate location.” That connects relativity to a purpose. Second, “In relativity, time can change depending on the observer.” That shows the idea changes with the situation. Today we learned the meaning, common uses, and even a funny office-style moment. Thanks for listening, and see you next time. Keep smiling and keep practicing!

1 00:00:00,000 --> 00:00:17,920 Dean：Hello everyone. Today’s word is kick. Kick means to hit or push with your foot. Kick also means to start something fast, like a strong start. In simpler words, kick is “hit with your foot.” Moli, how do you understand this word in Chinese? 2 00:00:18,420 --> 00:00:36,020 茉莉：“kick”通常表示用脚踢，或者用脚把东西推开，比如踢球、踢门。英语里也可以说成 hit with your foot。它是什么词性？最常见是动词，意思是踢。也常用来表示快速开始，比如“kick off”。 3 00:00:36,520 --> 00:00:48,040 Dean：Good. Kick is a verb. We often use it with “your foot” and in sports. Let’s use example sentences to learn. Example one: I kicked the ball to my friend. 4 00:00:48,540 --> 00:01:04,860 茉莉：这句话的意思是“我把球踢给了我的朋友”。场景是踢球或玩球，动作是用脚把球传出去。这里的 kick 就是“用脚踢”。Dean, can you explain this sentence in simpler English? 5 00:01:05,360 --> 00:01:11,440 Dean：Sure. It means I use my foot to push the ball to my friend. 6 00:01:11,940 --> 00:01:26,020 茉莉：第二个例句的意思通常是“有人用脚踢了我/我被踢了”，场景可能在打闹、运动或意外中。这里也还是用脚去踢这个动作。Dean, please go on and give the second example in English. 7 00:01:26,520 --> 00:01:30,680 Dean：Example two: The baby kicked when we changed the diaper. 8 00:01:31,180 --> 00:01:50,380 茉莉：第三个例句的意思是“音乐会很快开始了”，这里的 kick 更像是“让事情开始/拉开开始”的感觉，常见在表达“kick off”里。Dean, please give a simpler explanation for this last line. Then we will talk about word roots and origins next. 9 00:01:50,880 --> 00:01:56,960 Dean：Example three: The coach kicked off the meeting with a short speech. 10 00:01:57,460 --> 00:02:08,020 Dean：What are the word roots, affixes, and the etymology of kick? Tell the story of how this word was built and how its meaning changed. 11 00:02:08,520 --> 00:02:59,720 茉莉：好，我们先把 kick 当成一个“古老的动作词”。它在英语里本身不像那种一眼能看出前缀后缀的词，它更像是直接从很早以前的“踢、用脚猛地推一下”的动作里长出来的。英语里有些词后面会加前缀或后缀来改变意思，但 kick 这种词比较“朴素”，它的核心就是动作本身，所以我们讲词根词缀时反而要说，它几乎没有被拆成明显的部件。可是它的“家族”很活跃：比如 kick 和 kickstart、kicking 这些形式都很像同一个家的人，意思都会围绕“用力踢一下”或“快速开始”。另外，kick 也和一些表示脚步动作或轻微冲击的旧词有关系，随着时间流动，它逐渐稳定成今天这种常用的动词：既能表示真的踢，也能表示“开始某事”，就像你刚才听到的 kick off 那样。 12 00:03:00,220 --> 00:03:08,220 Dean：So what did this word originally mean? How did the meaning go from a physical action to an idea like “start quickly”? 13 00:03:08,720 --> 00:04:04,720 茉莉：可以把它想成一个从“脚下的力量”一路走到“事情的开场”的故事。很早以前，kick 这类词就对应一种很直接的动作：用脚突然发力，推动或踢出去。后来人们在生活里发现，有些事就像被“踢了一下”一样，会突然动起来、马上启动。于是同一个词就开始被用在更抽象的场景里，比如比赛开场、会议开头，用 kick 来表达“拉开序幕”“迅速开始”。同时它也会衍生出不同语气：kicked 比如更强调过去发生的动作；kicking 变成进行或一般的动作；而 kick off 把“开始”这层意思固定得更明显。最有趣的是，它明明起源是脚的动作，却能这么自然地变成“活动开场”的常用表达。下一部分我们将讲搭配、场景与互动。 14 00:04:05,220 --> 00:04:17,220 Dean：Imagine you are watching a football match at school. The ball moves fast, and the crowd says, “Kick it now!” In this kind of moment, how do we use this word? 15 00:04:17,720 --> 00:04:30,360 茉莉：第一个最常用的搭配是 kick the ball。它的语感很直观，就是“用脚把球踢出去”。在体育活动里很自然，尤其是教练或同学提醒你动作时。 16 00:04:30,860 --> 00:04:37,259 Dean：We can say, “Kick the ball to me.” It means use your foot and pass the ball. 17 00:04:37,759 --> 00:04:47,039 茉莉：这句话在球场上很地道。注意就是“踢球并把球传给对方”的感觉，比只说 kick 更具体。 18 00:04:47,539 --> 00:04:58,899 Dean：Now think about a school event. The teacher says, “Let’s start!” You feel the room becomes active right away. In this situation, how do we use kick? 19 00:04:59,399 --> 00:05:12,519 茉莉：第二个搭配是 kick off。它表示“开始某个活动/拉开开始”。常见于学校、比赛、会议这种需要“开场”的场景。语感通常比较正式或热闹一点。 20 00:05:13,019 --> 00:05:19,899 Dean：You can say, “The event will kick off at 3 p.m.” It means the event starts at 3 p.m. 21 00:05:20,399 --> 00:05:30,639 茉莉：这里的关键是 off 的意思让“开始”更明确，所以更像“开场/启动”。像时间安排时用特别自然。 22 00:05:31,139 --> 00:05:42,339 Dean：Next scene: you are studying with friends, and the music suddenly starts. Someone says, “The song is playing now.” What collocation can we use with kick here? 23 00:05:42,839 --> 00:05:56,439 茉莉：第三个搭配是 kick in。它表示“开始起作用”，常用来讲某个效果或功能“突然生效”。比如设备、药效、想法、节奏等带来明显变化。 24 00:05:56,939 --> 00:06:05,420 Dean：You can say, “My plan kicked in after I tried again.” It means it started to work after I tried again. 25 00:06:05,920 --> 00:06:20,000 茉莉：对，这里不是单纯的“开始”，而是“开始产生效果”。所以如果只是活动开头，用 kick off 更合适；如果是效果后来才出现，用 kick in 更贴切。 26 00:06:20,500 --> 00:06:34,740 Dean：Final scene for you: in class or at work, the boss says, “We need to begin with this first.” You want a natural sentence. Which is more natural: “Let’s kick off the meeting” or “Let’s kick the meeting”? 27 00:06:35,240 --> 00:06:59,240 茉莉：你问的是：在会议这种“开场”场景里选更自然的表达。答题要点是判断语义场景——会议要用 kick off 表示“开始”；kick the meeting 这种说法不够自然，因为 kick 通常和脚、球或具体动作搭配更紧密。接下来想了解这个词和它的近义词有什么区别。 28 00:06:59,740 --> 00:07:05,500 Dean：What are some common synonyms of “kick”? How are they different in usage? 29 00:07:06,000 --> 00:07:20,240 茉莉：“kick”的常见近义词可以从两个方向看：一个是表示用脚踢（比如踢球、踢门），另一个是表示“开始”（比如 kick off）。我们一个一个来对比，先看第一个。 30 00:07:20,740 --> 00:07:26,019 Dean：OK, what is the first synonym? How should I use it correctly? 31 00:07:26,519 --> 00:07:47,319 茉莉：第一是 “hit”。hit 的核心是“打中/击中”，不一定是用脚，所以比 kick 更通用、更泛。适合讲“用什么方式不重要，只要结果是被打到”。如果你要强调“用脚”，通常还是用 kick。例句：He hit the door with his foot. 32 00:07:47,819 --> 00:07:52,300 Dean：Got it. What about the next synonym? How is it different? 33 00:07:52,800 --> 00:08:17,600 茉莉：第二是 “strike”。strike 也表示“击打”，但更正式一些，语气更硬、更像书面或新闻里描述力量或打击。它不强调是脚，所以和 kick 的运动感不同。适合讲“突然的强力打击”，不适合随口描述日常踢球那种轻松动作。例句：The guard struck the attacker. 34 00:08:18,100 --> 00:08:21,620 Dean：Thanks. What is the third synonym? 35 00:08:22,120 --> 00:08:43,879 茉莉：第三是 “boot”。boot 比较像“用靴子踢”，更具体，也更有画面感。它通常强调鞋子或靴子的工具感，不是普通的“用脚踢”。适合讲更具体的场景，比如穿着靴子去踢某物。例句：He booted the ball into the air. 36 00:08:44,379 --> 00:08:50,460 Dean：Now the fourth synonym, if there is one. Ask me for a comparison. 37 00:08:50,960 --> 00:09:15,759 茉莉：第四可以用 “start”。start 和 kick 不一样：start 不是脚的动作，而是“开始”。所以它适合会议、活动、课程的开头，但不能像 kick 那样直接表达“用脚”的那层意思。用 start 会更中性，也更常见。例句：The class starts at nine. 38 00:09:16,259 --> 00:09:20,740 Dean：Can you summarize when to use which word? 39 00:09:21,240 --> 00:09:45,720 茉莉：总结一下：如果你想表达“用脚踢”，优先用 kick；如果你只关心“打中”，用 hit；如果你想要更正式、更强调“强力打击”的感觉，用 strike；如果你想突出“用靴子踢”，用 boot；如果只是谈“开始”，不用 kick，而用 start。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 40 00:09:46,220 --> 00:09:54,860 Dean：We have learned so much. Now let’s relax with a fun short story about the word kick. 41 00:09:55,360 --> 00:09:56,800 茉莉：什么故事？ 42 00:09:57,300 --> 00:10:16,980 Dean：Last Friday, I was in the school office. I wanted to hand in a form. The door was heavy, and it was stuck a little. My friend Sam said, “Just kick the door.” So I tried. I kicked the door… and the whole door opened too fast. Then everyone in the office looked at me. 43 00:10:17,480 --> 00:10:21,480 茉莉：哈哈，你是用脚踢门吗？然后他们怎么说？ 44 00:10:21,980 --> 00:10:41,659 Dean：Yes, with my foot. After that, the principal came in. She smiled and said, “Okay. Good energy!” Then she pointed to a big clock and said, “Our meeting will kick off in five minutes.” Right away, Sam whispered, “Now you must kick off your apology.” 45 00:10:42,159 --> 00:10:47,439 茉莉：kick off 是“开始”，那你道歉了吗？他们是不是笑了？ 46 00:10:47,939 --> 00:11:11,459 Dean：I did. I said, “I didn’t mean to make the door a drama.” The principal laughed and said, “No problem. But next time, kick the ball in practice, not the door in the office.” Then my phone rang, and I forgot my form. My plan kicked in only then. I ran back to my bag and found it. 47 00:11:11,959 --> 00:11:30,519 茉莉：这个故事太像真实生活了。总结一下：你先用 kick 表示用脚踢门；然后又用 kick off 表示会议开始；最后还用 kick in 表示“事情突然起作用”。你今天学到的词真的很有用！ 48 00:11:31,019 --> 00:11:48,139 Dean：Great review for today: kick can mean “hit with your foot,” and it can also mean “start quickly” with kick off. And when something starts working, we use kick in. Thanks for listening, and see you next time. Have a great day and… keep it light!

1 00:00:00,000 --> 00:00:16,320 Dean：Hi everyone. Today’s word is “era”. An era is a period of time in history. It means a section of time with a similar style or situation. In simple words, it means “a time period”. Moli, how do you understand it in Chinese? 2 00:00:16,820 --> 00:00:40,500 茉莉：“Era”指的是一个特定的历史或社会时期。中文也可以说“时代/时期”，强调在这一段时间里有相似的特点。英文对应可以说 era = a time period。它是什么词性呢？名词。最常见用法是谈历史时期，比如“the Victorian era”或“in the digital era”。 3 00:00:41,000 --> 00:00:59,879 Dean：Era is a noun. We use it for a period of time in history, like “the 1990s era”. We also use it for a period in life, like “the age of phones”, but we keep “era” for a specific time. Let’s learn with an example. Sentence 1: “The Roman era lasted for many years.” 4 00:01:00,379 --> 00:01:18,140 茉莉：这句话的意思是：罗马时期持续了很多年。场景是历史课或历史话题。这里的 “Roman era” 就是“罗马时代”。你可以理解为一个有范围的历史阶段。再用更简单的英文解释这句吧。 5 00:01:18,640 --> 00:01:31,280 Dean：In this sentence, “era” means a long time in history. It’s about a clear period, not a single day. Sentence 2: “We live in a new era of technology.” 6 00:01:31,780 --> 00:01:50,980 茉莉：这句话说的是：我们生活在一个新的科技时代。场景是日常聊天或科技新闻。这里的 “new era of technology” 指的是“科技发展带来的新阶段”，不是古代历史。请继续用更简单的英文解释这句。 7 00:01:51,480 --> 00:02:05,240 Dean：“New era of technology” means technology is changing in a big way. It is a common phrase in speaking. Sentence 3: “My childhood was a happy era for me.” 8 00:02:05,740 --> 00:02:25,100 茉莉：这句话的意思是：对我来说，我的童年是快乐的一段美好时期。场景是讲自己的生活经历。这里的 “era” 也可以用来形容个人生活中的一段时间，但语气更像“美好的阶段”。接下来我们再讲词根词缀与词源。 9 00:02:25,600 --> 00:02:31,040 Dean：Moli, what are the roots and affixes in era, and where does the word come from? 10 00:02:31,540 --> 00:03:34,260 茉莉：“Era”看起来很短，但它很有“故事感”。它本身不是那种能轻松拆出很多前缀后缀的词，更像是一个从更早语言里走来的整体。我们可以把它的来源当作“拼出来的历史”：在古代拉丁语里有一个词和“时间的安排、时间的计算”有关，后来经过法语再走进英语，最后就变成了今天的 era。你会发现它不是用来表达某一天，而是更像“被标记出来的一段时间”。至于同族词，我们不必强行找完全一样的拼法才能懂亲戚关系。比如“err”和“error”虽然看起来也像同一个家族，但它们走的是“犯错”的方向；而“err”和“era”的发音近一些，不代表意思相同。真正能让你理解“同一脉络”的，是你在英语里会经常看到 people use era 和时代概念一起谈，比如 age、period，这些词虽然不是同一来源，但都在做同一种事：把时间切成块来讲。 11 00:03:34,760 --> 00:03:45,640 Dean：So, Moli, tell me the story of its meaning. What did era mean originally, and how did it become “a period of history” today? 12 00:03:46,140 --> 00:04:43,740 茉莉：好，我们就当它是个小时间旅行者。起初它和“时间的计算、划分、记号”这类想法更接近，就像人们要把漫长的时间分出阶段，方便记录和交流。随着语言迁移，到了更晚的阶段，这个词逐渐变得更适合用来谈“某个时间段的特征”——不只是时间本身，还带上了这个时间段里人们经历的氛围或规律。于是你就会听到 people say things like “the Roman era”或“a new era of technology”，意思就更清楚了：它强调的是一个被公认的、相对完整的阶段，而不是随便的一段日子。最有趣的是，它明明只有四个字母，却能把“时间怎么被切分、被命名、被记住”都装进一个词里。下一部分我们就从这些“被命名的时间段”出发，讲它常搭配哪些词、在哪些场景里更自然，以及怎么在对话里用得更地道。 13 00:04:44,240 --> 00:05:01,680 Dean：Imagine you are in a museum shop, and the guide says, “This room is from the Victorian era.” You look at the posters and think, “Okay, I get it. It is a certain time in history.” In this situation, how do we use the word “era”? 14 00:05:02,180 --> 00:05:29,220 茉莉：第一个很实用的搭配是 the + 年代/时期 + era，比如 the Victorian era。它的语感是：这里的 era 是被“具体命名过的历史阶段”，不是随便讲一个年代。Victorian era 就是“维多利亚时代”，用的时候听起来很正式，也很常见于博物馆介绍、历史视频或课本里。 15 00:05:29,720 --> 00:05:37,560 Dean：Yes. We say, “This picture is from the Victorian era.” It means a specific period in history. 16 00:05:38,060 --> 00:05:50,699 茉莉：在这种场景里说 the Victorian era 非常自然，因为它对应的是一个有范围、被大家公认的时间段。你不用再加别的说明，听的人会直接明白是历史分段的一种说法。 17 00:05:51,199 --> 00:06:09,759 Dean：Now think about a school project. Your teacher asks you to talk about phones in the past and today. You might say, “Phones changed everything, and we live in a new era of technology.” What collocation should we use here in this school situation? 18 00:06:10,259 --> 00:06:36,819 茉莉：第二个搭配是 a new era of + 名词，比如 a new era of technology。它的感觉是：技术或生活方式正在进入一个“新的阶段”，这个阶段不是一天两天，而是一个明显的趋势开始了。这里的 of 表示“这个时代和什么相关”，所以你可以用在新闻、课堂讨论和日常聊天中。 19 00:06:37,319 --> 00:06:44,199 Dean：Right. Example: “People noticed a new era of technology after smart phones became common.” 20 00:06:44,699 --> 00:06:58,139 茉莉：这句话里 new era 的意思就是“新阶段”。如果你想让表达更自然，用 after + 事件 或 after + 时间点 来引出变化，会更像真实对话。 21 00:06:58,639 --> 00:07:15,759 Dean：Next, imagine you are writing about your life for a blog. You want to tell readers about a time that felt special to you, not a date in history. You might say, “My childhood was a happy era for me.” In this personal story, how do we use “era”? 22 00:07:16,259 --> 00:07:37,060 茉莉：第三个搭配是 a + 形容词 + era，比如 a happy era。它用来描述个人生活中的一段时期，强调感受或氛围。注意它不只是说“那段时间”，而是带一点“这段时间有自己的特点”的感觉，所以用在回忆、故事分享里很贴切。 23 00:07:37,560 --> 00:07:43,319 Dean：Example: “During my first year at college, it was a difficult era for me.” 24 00:07:43,819 --> 00:07:57,899 茉莉：这里 difficult era 也同样是“个人经历的阶段”，听起来比普通的 time period 更有画面感。你可以用不同形容词来配合你的经历，比如 happy、busy、hard。 25 00:07:58,399 --> 00:08:23,359 Dean：Last one. Imagine you watch the news and someone says, “We are in an era of change.” Think about the most natural way to complete this sentence: “There is an ___ of technology in our city.” Is the blank best filled with “era” as a standalone word, or with “era of” plus a noun? 26 00:08:23,859 --> 00:08:52,339 茉莉：互动问题是：在新闻或讨论变化的场景里，句子 “There is an ___ of technology in our city.” 空格处应该怎么填。答题要点是看固定搭配：更自然的是 “an era of + 名词”，也就是 era 后面跟 of 和你要说的领域或现象，比如 technology。接下来我们就想了解这个词和它的近义词在用法上有什么区别。 27 00:08:52,839 --> 00:08:57,959 Dean：What are some common synonyms of “era”? How are they different in usage? 28 00:08:58,459 --> 00:09:08,699 茉莉：“era”的常见近义词有：age、period、time、epoch、stage。我们一个一个来对比，先看第一个。 29 00:09:09,199 --> 00:09:13,999 Dean：Great. What is the first synonym? How should I use it correctly? 30 00:09:14,499 --> 00:09:45,699 茉莉：第一个是 age。age 和 era 都能表示“一段时间”，但 age 更常用来讲“更大的阶段”，有时也带有一种历史感或文化感。适用场景：历史、文化、社会发展里更常见，比如 “the Age of…” 或 “in the Stone Age”。语气/正式程度：通常和 era 一样偏正式或书面，但 age 也很常见于一般表达。例句：The age of computers began in the 20th century. 31 00:09:46,199 --> 00:09:51,479 Dean：Okay, I understand. What about the next synonym? How is it different? 32 00:09:51,979 --> 00:10:26,859 茉莉：第二个是 period。period 和 era 的核心差别是：period 更像“中间有起点和终点的时间段”，强调时间的长度或安排；era 更强调这个阶段的特点或风格。适用场景：作业、说明、讲事实时很自然，也能用于生活里。语气/正式程度：中性，比较通用。搭配上：常用 a period of + 名词，比如 a period of study。例句：I had a difficult period at work last year. 33 00:10:27,359 --> 00:10:31,519 Dean：Thanks. What is the third synonym? 34 00:10:32,019 --> 00:11:07,379 茉莉：第三个是 time。time 的意思更宽，通常指“时间”这个大概的概念，不一定是一个被命名的阶段。你可以用 time 来说一个时期，但它不如 era 那样强调“一个有特点的阶段”。适用场景：日常生活表达很常见，比如 “at that time”，但要表达“历史阶段”时通常不如 era 精确。语气/正式程度：中性口语也能用。搭配上：常和 at、in、for 等结构一起用。例句：I learned a lot at that time. 35 00:11:07,879 --> 00:11:12,359 Dean：If there is another synonym, please tell me the next one. 36 00:11:12,859 --> 00:11:43,099 茉莉：第四个是 epoch。epoch 和 era 相似，都能表示一个重要的“历史阶段”，但 epoch 通常更正式、也更强调“划时代”的意义，像是一个重大的转折点。适用场景：科学、历史、重要变革的描述里更常见。语气/正式程度：偏正式、学术。搭配上：常见 an epoch of + 名词。例句：The internet created an epoch of new communication. 37 00:11:43,599 --> 00:11:48,879 Dean：Okay. Finally, can you summarize when to use which word? 38 00:11:49,379 --> 00:12:23,779 茉莉：总结一下：如果你要说“被大家认出来的、带特点的时间段”，优先用 era，比如 “the Victorian era”。如果你更想强调“有起止的时间长度或安排”，用 period 更合适。time 更宽泛，通常表达一般的时间点或阶段，不一定有“阶段特征”。如果是“非常重要的转折点、划时代的阶段”，用 epoch 更有力量也更正式。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:12:24,279 --> 00:12:32,279 Dean：We have learned so much. Now let’s relax with a fun short story with today’s word “era”. 40 00:12:32,779 --> 00:12:35,179 茉莉：什么故事呀？快说快说！ 41 00:12:35,679 --> 00:12:54,239 Dean：Last Friday, I was at work. My boss said, “Team, we are in a new era of teamwork.” But then the printer stopped. Everyone looked confused. I said, “This is not teamwork. This is a dark era of printing.” 42 00:12:54,739 --> 00:13:01,619 茉莉：哈哈，dark era of printing 也太形象了！后来呢？你们真的就一直等打印机吗？ 43 00:13:02,119 --> 00:13:21,319 Dean：No, we tried to fix it. The IT person arrived and said, “In the Victorian era, people used letters, not printers.” Everyone laughed, because our tickets were still stuck in the printer. So my boss smiled and said, “Okay, maybe we need a new era of patience, too.” 44 00:13:21,819 --> 00:13:36,219 茉莉：我明白了，这个故事里 “era” 用法很灵活：既能说 a new era of + 名词，也能用 a + 形容词 + era 来吐槽自己的处境！ 45 00:13:36,719 --> 00:13:54,159 Dean：Exactly. And by the end, we finally got the print. My boss said, “Great job. We survived the era.” I replied, “Yes, and the era survived us.” Thanks for listening today. Keep using your words, and have a cheerful day!

1 00:00:00,000 --> 00:00:14,400 Dean：Today we study the word “edible”. Edible means “safe to eat”. It also means “something you can eat”. Easy words: you can eat it. Moli, how do you understand it in Chinese? 2 00:00:14,900 --> 00:00:28,339 茉莉：“edible”的意思是：可以吃的、能入口的，而且通常是对人安全的食物。English meaning: safe to eat. 这个词是什么词性，常怎么用？ 3 00:00:28,839 --> 00:00:41,799 Dean：Edible is an adjective. We use it to talk about food or things you can eat. Now let’s use an example to learn it. Example 1: The fish is edible, but it is not fresh. 4 00:00:42,299 --> 00:00:57,500 茉莉：这句话的意思是：这条鱼是可以吃的，但它不新鲜。这里的 edible 指的是“对人来说安全、能吃”的意思。想一想更简单的英文，你会怎么说这句里 edible 的感觉？ 5 00:00:58,000 --> 00:01:10,640 Dean：In this sentence, “edible” sounds like “safe to eat”. It does not talk about taste or smell. Example 2: This fruit is edible, even for beginners to try. 6 00:01:11,140 --> 00:01:24,900 茉莉：这句话的意思是：这种水果是可以吃的，新手也可以尝试。这里的 edible 用来说明“能不能吃”，而不是好不好吃。Dean, can you explain the sentence in simpler English? 7 00:01:25,400 --> 00:01:35,960 Dean：It means the fruit is safe to eat. “Edible” helps us know it is okay for food. Example 3: Only take edible parts of the plant. 8 00:01:36,460 --> 00:01:48,620 茉莉：这句话的意思是：只拿植物里可以吃的部分。这里的 edible 是用在“植物的某些部位是否能吃”的情况。接下来讲词根词缀与词源。 9 00:01:49,120 --> 00:01:58,719 Dean：Moli, in “edible,” what are the word root, the affixes, and what is the etymology? Tell it like you are building the word step by step. 10 00:01:59,219 --> 00:03:41,620 茉莉：好，我们先把 edible 拆开想。它看起来像是由两部分拼起来的：一个是 ed，和“吃”有关；另一个是 ible，常常出现在形容词里，用来表示“可以……的、适合……的”。所以 edible 就像在说“能被吃的东西”。你可以把它理解成“可食用”的意思，是一种很实用的判断：这东西入嘴之后算不算能吃、合不合适。 再说点“像亲戚一样”的词。比如 credit 这类词不是同样的部分来源，但大家会发现拼法里也有那种“看起来很像”的结构。更接近同族思路的其实是那些以 ed 开头并和吃、处理食物有关的词，虽然它们的具体形态会变化，比如有的更偏向“饮食动作”，有的偏向“可被吃的结果”。它们之间的区别通常在于：edible 更强调结果和状态，也就是“能不能吃”，而别的同类词可能更强调“过程”或“行为”。 最后讲身世故事。edible 来自拉丁语的 edere，原意和“吃、取食”紧密相关。后来语言演化时，拉丁语的表达方式逐渐被吸收进法语和英语体系里，那个表示“可以……的”的形容词感慢慢稳定下来，最后在英语里形成 edible 这种固定用法。于是它从“与吃有关”的根源意义，逐渐变成今天这种“可以安全食用”的判断词。 我觉得最有趣的是：它的意思不是凭空来的，而是从“吃”的古老根出发，再加上“可……的形容词感”，一步步变得很直接、很生活化。下一部分我们就来讲搭配、常见场景和互动方式。 11 00:03:42,120 --> 00:03:50,280 Dean：Great! So what did this word originally mean, and how did it become the word we use today for “safe to eat”? 12 00:03:50,780 --> 00:04:05,500 Dean：Yesterday, you open a small kitchen box from a friend. You want to try the snack, but the label is missing. You look at it and think, “Is it edible?” What collocations can we use for this kind of situation? 13 00:04:06,000 --> 00:04:29,519 茉莉：第一个搭配是 edible food。它的语感很直接，就是把 edible 当作“可食用的、能吃的食物”的判断。日常里你会更自然地说某种食物是 edible food，尤其当你在强调“能不能吃”而不是“好不好吃”。如果对方给你的是不确定来源的东西，这个搭配会更贴合你刚才说的那种焦虑感。 14 00:04:30,019 --> 00:04:37,859 Dean：In this case, you can say: “Is it edible food?” Example: “Only give it edible food for the cat.” 15 00:04:38,359 --> 00:04:53,559 茉莉：在这种场景说 edible food 很自然，因为你在讲“喂给猫的东西是不是能吃的”。这里的 edible 用来做安全性和适用性的判断，比起只说 edible，你会更具体地指向“食物”本身。 16 00:04:54,059 --> 00:05:11,499 Dean：Now imagine you are at school for a science lab. You have to write a safety rule on the wall. Your teacher says, “Do not put anything in your mouth.” Then they mention, “Only edible things are allowed.” What collocation fits this school rule? 17 00:05:11,999 --> 00:05:32,319 茉莉：第二个搭配是 edible parts。意思是“可食用的部分”，常用于植物、食材或者某个物体的“部位”层面。它的语感有点像在做分类：哪些部分可以吃，哪些部分不行。你在写实验或安全规则时用它，会特别清楚、很有条理。 18 00:05:32,819 --> 00:05:43,539 Dean：You can say: “Only the edible parts are safe.” Example: “Peel off the skin. The edible parts are inside.” 19 00:05:44,039 --> 00:05:58,919 茉莉：edible parts 这里特别自然，因为你在讲“去皮之后哪些是能吃的部分”。如果你想更精确描述“部分”，用 parts 比用 food 更贴合，也更符合你刚才的学校场景和规则写法。 20 00:05:59,419 --> 00:06:16,699 Dean：Last one. You watch a news video about a street market. The sellers say, “Our product is edible.” People ask, “Is it safe to eat?” It is not about taste. It is about safety. What collocation would you expect in such news? 21 00:06:17,199 --> 00:06:38,639 茉莉：第三个搭配是 edible product。它的语感更像在新闻或公告里，因为 product 更正式、更接近“产品/商品”的表达。你用 edible product 来强调“这个东西作为产品是可以食用的”，跟我们平时说 edible food 的日常口语相比，会更偏公共信息。 22 00:06:39,139 --> 00:06:49,059 Dean：In news, you may hear: “This edible product is safe to eat.” Example: “The company says the edible product is tested.” 23 00:06:49,559 --> 00:07:02,999 茉莉：edible product 很适合新闻语境，因为它是对“商品”的判断，而不是对某个人做饭的日常评论。这里的 tested 通常指检测过，整体语气更正式。 24 00:07:03,499 --> 00:07:21,099 Dean：Now your turn. If you see “edible” next to “parts,” which collocation should you use? Think of plants or food portions. Or you can make one sentence for listeners: choose one collocation and write a simple sentence. What will you say, Moli? 25 00:07:21,599 --> 00:07:45,759 茉莉：好的，我来复述互动问题。你需要在听到 “edible” 和 “parts” 放在一起时选出对应搭配，也就是用来表示“可食用的部分”。或者你也可以用一个搭配造一个简单句。重点是让句子体现出你在判断“能不能吃”，而不是在说味道。接下来想了解这个词和它的近义词有什么区别，所以你们可以先试着说你选的搭配和句子给我听。 26 00:07:46,259 --> 00:07:52,019 Dean：What are some common synonyms of “edible”? How are they different in usage? 27 00:07:52,519 --> 00:08:07,719 茉莉：“edible”的常见近义词可以有：eat able、consumable、fit to eat、safe to eat、tolerable（更偏“能入口、勉强可吃”但不强调好吃或一定安全）。我们一个一个来对比，先看第一个。 28 00:08:08,219 --> 00:08:13,819 Dean：OK, what is the first synonym? How should I use it correctly? 29 00:08:14,319 --> 00:08:39,919 茉莉：第一个是 eat able。它的意思和 edible 很接近，指“可吃的”。但它更像把意思分开来讲，形式上不如 edible 标准自然，所以日常更建议你用 edible。适用场景：你想强调“能不能吃”时，但在大多数正式和自然表达里用 edible 更好。例句：This snack is edible, so it is eat able for everyone. 30 00:08:40,419 --> 00:08:45,219 Dean：Got it. What about the next synonym? How is it different? 31 00:08:45,719 --> 00:09:12,119 茉莉：第二个是 consumable。它强调“可以被消耗/食用的”，有一点更“功能性”的感觉，常见于说明书、清单、管理类语境。适用场景：食品安全、仓储、使用规定、成分是否适合食用。语气上通常比 edible 更偏正式或偏“规则语言”。例句：Only consumable items are allowed in this room. 32 00:09:12,619 --> 00:09:15,339 Dean：Thanks. And the third synonym? 33 00:09:15,839 --> 00:09:42,879 茉莉：第三个是 fit to eat。它更强调“符合可食用标准”，常用于判断食物是否合格或是否适合被吃，但不一定像 edible 那样总是简短直接。适用场景：你看到变质迹象、检查标签、或做更认真标准的判断时。语气通常更严谨。例句：The fruit looks old, but is it fit to eat? 34 00:09:43,379 --> 00:09:47,059 Dean：OK. Is there a fourth synonym we should know? 35 00:09:47,559 --> 00:10:19,239 茉莉：第四个是 safe to eat。它和 edible 最接近，但重点会更明确地放在“安全性”。适用场景：当你想告诉别人“不要担心，有风险吗”，尤其是食品安全、医疗/营养建议、公告类信息。语气上通常比 edible 更强调“风险控制”。搭配上你更常看到 safe to eat food 或 safe to eat products。例句：When in doubt, choose food that is safe to eat. 36 00:10:19,739 --> 00:10:28,219 Dean：Great. If there are no more, can you summarize when to use which word? 37 00:10:28,719 --> 00:10:55,919 茉莉：总结一下：如果你想说“能吃、可食用”的一般判断，用 edible 最自然。想更正式、更像规定或清单，用 consumable。想强调“是否达标、是否符合可吃标准”，用 fit to eat。想把重点放在“安全性”，用 safe to eat。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 38 00:10:56,419 --> 00:11:04,579 Dean：We have learned so much. Now let’s relax with a fun short story related to “edible”. 39 00:11:05,079 --> 00:11:07,639 茉莉：什么故事？我很期待！ 40 00:11:08,139 --> 00:11:24,779 Dean：It’s Monday morning at my office. In the break room, there is a big box of snacks. The label says, “edible product.” But the box has no brand. My boss looks serious and says, “Only edible products are allowed.” 41 00:11:25,279 --> 00:11:30,879 茉莉：听起来有点像规则办公室！然后呢？你们真的都不敢吃吗？ 42 00:11:31,379 --> 00:11:50,899 Dean：Then my coworker, Alex, opens the box and says, “Relax! Look, it is edible food.” He picks one snack and smiles. But I notice something. The snack has a sticker: “Only edible parts.” 43 00:11:51,399 --> 00:11:56,679 茉莉：哇，原来还要分“能吃的部分”！那你们怎么做的？ 44 00:11:57,179 --> 00:12:21,339 Dean：So we start a safety mission. Alex tries one piece. I check the sticker. My boss says, “If it is not edible parts, do not put it in your mouth.” Finally Alex finds the tiny “edible part” at the corner. He takes it… and it tastes like “office dust,” but at least it was safe. 45 00:12:21,839 --> 00:12:36,399 茉莉：哈哈！这个故事的笑点是：大家先被“edible product”的正式感吓到，又用“edible food”和“edible parts”来判断。最后发现“安全”不一定等于“好吃”，但至少规则很有用！ 46 00:12:36,899 --> 00:13:00,099 Dean：Today we used “edible” in real moments: “edible food,” “edible parts,” and “edible product.” We also learned the idea of focus: eatable things, the right parts, and safety. Thanks for listening. See you next time, and remember: be curious, and stay safe when you eat!

1 00:00:00,000 --> 00:00:16,960 Dean：Today’s word is differ. It means “to be different.” It can also mean “not the same.” Let me say it in a simpler way: differ means “be not the same.” Moli, how do you understand this word in Chinese? 2 00:00:17,460 --> 00:00:38,100 茉莉：“differ” 的意思是“不同”。中文里也可以说“和……不一样”。英文对应可以用 not the same. 这个词是什么词性，常怎么用？它通常是动词，用来表示“人或事物不一样”，常见结构是 differ from 表示“与……不同”。 3 00:00:38,600 --> 00:00:49,960 Dean：It is a verb. We use it to say two things are not the same. Now let’s use example sentences to learn. Example 1: My opinion differs from yours. 4 00:00:50,460 --> 00:01:05,980 茉莉：这句话的意思是：我和你对某件事的想法不一样。场景很常见，比如聊天或讨论时。这里的 differ from 是“与……不同”的意思。Dean, please explain this sentence in simpler English. 5 00:01:06,480 --> 00:01:13,200 Dean：It means you and I think differently. It is a polite way to say “not the same.” 6 00:01:13,700 --> 00:01:18,180 Dean：Example 2: The two plans differ in price. 7 00:01:18,680 --> 00:01:37,240 茉莉：这句话的意思是：这两种方案在价格方面不同。场景是工作或生活中选方案，比如比较价格。这里的 differ in 表示“在某个方面不同”。Dean, please continue with a simpler English explanation for how differ is used here. 8 00:01:37,740 --> 00:01:42,220 Dean：It means the price is not the same for the two plans. 9 00:01:42,720 --> 00:01:47,360 Dean：Example 3: People differ in how they learn languages. 10 00:01:47,860 --> 00:02:06,580 茉莉：这句话的意思是：每个人学习语言的方法不一样。场景是老师和学生讨论学习方式。这里的 differ in 表示“在……方面不同”，后面常接方式、方法或特点。接下来讲词根词缀与词源。 11 00:02:07,080 --> 00:02:19,080 Dean：Let’s dig deeper, Moli. What are the word roots and affixes of differ, and what is its etymology? Tell the story of how the spelling and meaning came together. 12 00:02:19,580 --> 00:03:00,860 茉莉：好，我们就把 differ 想成一个“拆开也能理解”的词。它看起来短，但其实来自更古老的拉丁语表达。这个词的核心和“分开、不同”的意思有关，所以你会感觉 differ 跟“分辨、差异、隔开”这种想法是同一条路上的。我们不把它硬拆成很多零件，因为 differ 这个词更像是从古代词形一路演化到今天的样子，不过它的“家族感”很强：比如差别这个概念相关的词，像 difference，differently，different，都能让你抓到同一种感觉。它们的关系就像是一家人，虽然穿的衣服不一样，但表达的方向都围绕“不同”展开。 13 00:03:01,360 --> 00:03:10,640 Dean：Nice. So what did differ originally mean, and how did its meaning change over time into today’s “not the same”? 14 00:03:11,140 --> 00:04:20,100 茉莉：故事可以这样讲：在更早的语言里，拉丁语里有一个意思接近“分开、拿开、让它不一样”的表达。后来进入英语之后，differ 这件事慢慢从“把东西分开”变成“在看法、情况或结果上不一样”。你可以想象，两个东西被分开以后，最直观的感受就是它们不相同；所以 differ 从“分开带来的状态”逐渐变成“它们不一样”的表达方式。再往后，英语用 differ 来描述很多领域里的差异：观点不同、价格不同、做事方式不同，这些都是“同一个东西的不同版本”。而同族词也跟着扩展出更细的用法，比如 different 更强调“在本质上不是同一种”，difference 是名词，专门谈“差异这个结果”，differently 是副词，用来说明“用不同的方式”。我觉得最有趣的是：它的意义并不是突然跳出来的，而是从“分开”的画面慢慢走到“比较出来的不同”，最后就变成了我们每天都在用的简单句子。下一部分我们就来聊聊它最常见的搭配、典型场景和互动方式。 15 00:04:20,600 --> 00:04:55,320 Dean：Imagine you are in class and you changed your mind after a new example. You say, “My idea is not the same as yours.” In this situation, how do we use differ? 16 00:04:55,820 --> 00:05:08,940 茉莉：第一个最常用的搭配是 differ from。它表示“与……不同”，强调对比对象。比如在课堂讨论里，你和同学看法不一样，就很自然用 differ from。 17 00:05:09,440 --> 00:05:18,400 Dean：Right. Use “differ from” to show two opinions are not the same. Example: My idea differs from yours. 18 00:05:18,900 --> 00:05:30,900 茉莉：这句话很自然，因为“differs from”就是在做对比，而且是比较礼貌、适合讨论的表达。idea 这种名词也很常见，搭配起来很顺。 19 00:05:31,400 --> 00:05:43,560 Dean：Now picture a work meeting. The team has two budgets, and the numbers are not equal. Someone asks, “Are they the same?” What should you say with differ in this situation? 20 00:05:44,060 --> 00:05:59,740 茉莉：第二个搭配是 differ in。它表示“在某个方面不同”，后面通常接 price、size、style、method 这类“方面”。在会议里谈预算、数字差异，用 differ in 特别贴切。 21 00:06:00,240 --> 00:06:08,560 Dean：Use “differ in” for the part that is different. Example: The two plans differ in price. 22 00:06:09,060 --> 00:06:19,300 茉莉：这里“price”就是不同的那一项，所以 differ in price 很符合场景。注意它不是在说谁对谁错，只是在说明差别点。 23 00:06:19,800 --> 00:06:31,640 Dean：Let’s go to a daily situation. You ask two friends, “How do you learn English?” They both give different answers. What would you say about that? 24 00:06:32,140 --> 00:06:46,220 茉莉：第三个搭配是 differ in how… 这个结构更具体，表示“在……的方式/方法上不同”。当你谈学习方法、做事方法、表达方式时，用 how 最合适。 25 00:06:46,720 --> 00:06:51,200 Dean：You can say: People differ in how they learn English. 26 00:06:51,700 --> 00:07:01,460 茉莉：这种表达在聊天里很自然，而且比“people are different”更精确。这里的 how 帮你把差异点落到“方法”上。 27 00:07:01,960 --> 00:07:31,720 Dean：Great job. Now think about news or reports. You read a sentence like: “The numbers are not the same in different places.” In this kind of writing, you may see differ used in one more common way. Moli, how would you complete this idea: Which one sounds more natural—“The results differ in place” or “The results differ from place”? Choose one, and make your own short sentence too. 28 00:07:32,220 --> 00:07:58,940 茉莉：我会先复述互动要点：你在新闻或报告里想表达“结果在不同地方不一样”。需要你在 differ from 和 differ in 之间选更自然的搭配，然后用它造一个简短句子。做题时记住：from 更像是在对比具体对象；in 更像是在说“差异点在哪里”。接下来我们就来了解这个词和它的近义词有什么区别。 29 00:07:59,440 --> 00:08:05,520 Dean：What are some common synonyms of differ? How are they different in usage? 30 00:08:06,020 --> 00:08:13,860 茉莉：常见近义词有：be different，vary，contrast，disagree。我们一个一个来对比，先看第一个。 31 00:08:14,360 --> 00:08:19,480 Dean：OK, what is the first synonym? How should I use it correctly? 32 00:08:19,980 --> 00:08:47,340 茉莉：第一个是 be different。它的意思很接近“not the same”，但更像是描述状态，而不是强调“在对比中不一样”。适用场景更日常、更直接，通常不如 differ 那么常用作固定结构。语气通常中性，不太正式。例句：This answer is different from mine. （更像是在说“状态是不同”，而不是在强调“差异点来自哪里”。） 33 00:08:47,840 --> 00:08:51,840 Dean：Got it. What about the next synonym? How is it different? 34 00:08:52,340 --> 00:09:22,580 茉莉：第二个是 vary。vary 比 differ 更强调“变化”，常用于数字、程度、天气、结果等“会变动的东西”。语气上也比“be different”更偏描述过程或趋势，常见于稍正式或书面表达，但仍适合学习者用。搭配上你会更常看到 vary from… to… 或 vary in… 这种结构。例句：Prices vary from city to city. 35 00:09:23,080 --> 00:09:26,120 Dean：Good. What about the third synonym? 36 00:09:26,620 --> 00:09:49,659 茉莉：第三个是 contrast。contrast 的重点是“形成对比”，通常暗示你在讲两件事的差异，但它更像是“对比分析”的动作，不只是“不同”。语气通常更偏正式，常见于写作和课堂表达。搭配上更常用 contrast A with B。例句：We should contrast these two ideas. 37 00:09:50,159 --> 00:09:58,959 Dean：Thanks. Do you have another common synonym? 38 00:09:59,459 --> 00:10:24,739 茉莉：第四个是 disagree。它更不像 differ 只是“不同”，而是强调“意见不一致到产生分歧”。适用场景是你在讨论时不赞同对方，语气更强一点，通常带一点冲突感。搭配上常用 disagree with 或 disagree about。例句：I disagree with your plan. 39 00:10:25,239 --> 00:10:29,079 Dean：Can you summarize when to use which word? 40 00:10:29,579 --> 00:11:00,619 茉莉：总结一下：想表达“事实或情况不一样、观点不同”，最稳的是 differ（尤其是 differ from / differ in）。如果你想强调“会变化、程度或数值不固定”，用 vary。想表达“在写作或讲解中把两件事拿来做对比”，用 contrast。想表达“我不认同你”，带分歧的感觉更强，用 disagree。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 41 00:11:01,119 --> 00:11:08,639 Dean：We have learned so much. Now let’s relax with a fun short story with differ. 42 00:11:09,139 --> 00:11:11,699 茉莉：什么故事？我想听！ 43 00:11:12,199 --> 00:11:37,639 Dean：Last Friday, I was at the office. My coworker, Sam, brought two new energy drinks for the team. He said, “One is for focus. One is for sleep.” I asked, “Is it the same can?” Sam smiled. “No. They differ.” Then he added, “The colors differ from each other, and the flavor differs too.” So I chose the “focus” one and took one sip. 44 00:11:38,139 --> 00:11:43,099 茉莉：然后呢？你真的变得更专注了吗？还是更困了？ 45 00:11:43,599 --> 00:12:25,199 Dean：Two minutes later, my eyes were heavy. I tried to work, but my brain was moving like a slow video. Sam walked by and asked, “How is it?” I said, “My focus differs from your promise.” He laughed and said, “Of course. The two drinks differ in taste, and also in effect!” Then the funny part happened. Our boss came in and drank the other can. She said, “Great! This one helps me sleep… right now.” We all looked at Sam. He looked at the cans and said, “Wait… I wrote ‘focus’ and ‘sleep’ on the wrong labels.” The whole team started laughing. 46 00:12:25,699 --> 00:12:41,859 茉莉：哈哈，这个故事太真实了！所以这次 differ 的关键用法就是：用 differ from 来表示“彼此不同”，用 differ in 来表示“在某方面不同”。原来它还能用来吐槽和翻车！ 47 00:12:42,359 --> 00:13:03,639 Dean：Yes! Today we used differ to talk about differences in opinions, plans, and even energy drinks. Remember: differ from, differ in, and differ in how… Now take a deep breath, relax, and enjoy your English learning. See you next time!

1 00:00:00,000 --> 00:00:16,160 Dean：Hello everyone. Today’s word is conform. In English, conform means to behave in the way that rules or people expect. It means to follow the same way. Moli, how do you understand this word in Chinese? 2 00:00:16,660 --> 00:00:40,980 茉莉：conform 的意思是“遵守规则或大家希望的做法”，让自己的行为和他人保持一致。English small idea: “follow rules” 它通常是动词，常用在“遵守/符合规定、按要求做事”这种语境里。这个词也常用于说“某人不太愿意改变，还是会照大家的方式来”。 3 00:00:41,480 --> 00:00:55,560 Dean：Conform is a verb. It often means “follow rules” or “fit in with what others do.” Now let’s use examples to learn it. Example 1: Please conform to the safety rules. 4 00:00:56,060 --> 00:01:16,700 茉莉：这句话的意思是：请你遵守安全规则。场景是工作场所或课堂，老师或负责人提醒大家必须按规定做事。 需要注意的词是 conform，它表示“按要求去做、符合规则”。 Dean, can you explain this sentence in simpler English? 5 00:01:17,200 --> 00:01:26,640 Dean：Sure. It means you should follow the safety rules. You should not ignore them. Example 2: He tries to conform at school. 6 00:01:27,140 --> 00:01:48,260 茉莉：这句话通常表示：他在学校努力让自己和大家的做法一致，想要融入。场景是社交和适应环境。 需要注意的词是 conform，它不是“学会一个技能”，而是“调整自己的行为去迎合期待”。 Dean, please keep explaining in simpler English. 7 00:01:48,760 --> 00:01:59,160 Dean：It means he tries to fit in with what people do at school. He wants to be like the others. Example 3: The design must conform to the law. 8 00:01:59,660 --> 00:02:17,100 茉莉：这句话的意思是：这个设计必须符合法律规定。场景是项目审批、合规要求或正式流程。 需要注意的词是 conform，在这里是“必须满足规则/法律的要求”。 接下来我们讲词根词缀与词源。 9 00:02:17,600 --> 00:02:24,160 Dean：What are the word roots and affixes in conform, and where does the word come from? 10 00:02:24,660 --> 00:03:21,300 茉莉：我们先想象一下这个词的“拼装”。conform 里面有 con 和 form。con 这个部分有点像“在一起、共同”的感觉，就像把人或东西拉到同一个方向；form 就是“形状、形式”的意思。所以 conform 这两个部分放在一起时，就像在说“把某种形状或做法放到同一条线上”，也就是让行为和期待变得一致。你看它为什么和“follow rules”那么贴近：不是随便做，而是让自己走进那个“共同的形式”。同族词里，比较像的亲戚是 form 这家族，比如 reform，意思是“重新形成、改革”，它更强调改变过程；还有 information，表面上也带 form 的影子，但它不直接讲“遵守”，而是在讲信息“形成出来的内容”。当然，form 这条线不会每次都只指规则，但它总能让我们抓住“形式和结构”的画面。 11 00:03:21,800 --> 00:03:28,200 Dean：So what did conform originally mean, and how did it change into today’s meaning? 12 00:03:28,700 --> 00:04:27,740 茉莉：它的身世也像一个小故事。很早以前，这个家族来自拉丁语的用法。那时候 con 大概有“together”的味道，form 则常常跟“shape”或“give shape”有关。慢慢地，人们开始用它来描述“让某人或某物变得同样的样子”，比如在一群人中调整行为，让大家都看起来像同一套规则下长出来的东西。后来，当社会生活越来越强调秩序，conform 就更常被用来讲“在群体里按规则行事”，于是它逐渐更偏向“遵从、符合要求”。有时它也会带一点社交意味：你不是在发明新玩法，而是先适应大家的标准，让自己看起来“合乎规范”。我觉得最有趣的是，它从“形状的同一”一步步变成了“行为的同一”。下一部分我们就来讲更实用的搭配、常见场景和互动方式。 13 00:04:28,240 --> 00:04:46,960 Dean：Imagine you are in an office. Your manager asks everyone to use the same safety gear. You feel uncomfortable, but you still want to keep your job. What would you say you should do with yourself in that moment? Moli, how do we use the word in this kind of situation? 14 00:04:47,460 --> 00:05:04,100 茉莉：第一个最实用的搭配是 conform to. 它的意思是“符合……/遵从……”。语感上很像“把自己调整到要求的标准上”。在这种工作场景里，说 conform to safety rules 就很自然，也很正式。 15 00:05:04,600 --> 00:05:08,920 Dean：For example: You must conform to the safety rules at work. 16 00:05:09,420 --> 00:05:23,340 茉莉：这句话里 must conform to 的表达很地道。conform to 后面可以接规则、标准、要求，比如 safety rules、the dress code 这类。它强调“照着做、不要偏离”。 17 00:05:23,840 --> 00:05:41,280 Dean：Now think about school life. On the first day, your teacher says, “Please follow the school dress rules and do not change your schedule without permission.” Everyone is watching what you do. Moli, in this school situation, how do we use conform? 18 00:05:41,780 --> 00:05:59,380 茉莉：第二个搭配是 conform to regulations. 它比单纯说 rules 更偏“正式规定、制度层面的规章”。用在学校时，就会让听起来更像通知或规则要求，比如规定你穿什么、什么时候上课、怎么做登记。 19 00:05:59,880 --> 00:06:12,520 Dean：Example: Students should conform to the school regulations. 20 00:06:13,020 --> 00:06:28,060 茉莉：这句在课堂或校园公告里很常见。students should conform to 体现的是“应该遵守”，并且范围更正式。注意它不是“想要适应就行”，而是“需要照规定来”。 21 00:06:28,560 --> 00:06:46,320 Dean：Third, imagine you are at a news event or a public meeting. A reporter says, “The new building design must follow the rules.” People care about safety and legal checks. Moli, how do we use the word there? 22 00:06:46,820 --> 00:07:03,300 茉莉：第三个搭配是 conform to the law. 这个就非常常用于新闻、法律、审批等场景，意思是“符合法律”。它比 conform to rules 更强，因为它把“规则”直接落到“法律层面”。 23 00:07:03,800 --> 00:07:14,680 Dean：Example: The plan must conform to the law. 24 00:07:15,180 --> 00:07:26,060 茉莉：对，这里 must 就很关键，表示“必须满足”。在新闻或正式报道里，用 conform to the law 会更有权威感，也更准确。 25 00:07:26,560 --> 00:07:45,760 Dean：Let’s make it interactive. Imagine you are writing a short email at school. Choose the more natural sentence: A) Please conform to the rules in class. B) Please conform the rules in class. Moli, repeat the question and tell us which one is correct, and why. 26 00:07:46,260 --> 00:08:10,420 茉莉：题目是：在学校写邮件时，选更自然的句子。重点看选项 A 和 B 的差别在介词。正确答案是 A。因为 conform 后面通常要接 to，表示“遵从/符合”。B 少了 to，语法不自然。你也可以记成一个固定结构：conform to + 规则。 27 00:08:10,920 --> 00:08:16,840 Dean：What are some common synonyms of this word? How are they different in usage? 28 00:08:17,340 --> 00:08:26,140 茉莉：conform 的近义词常见有：comply、adhere、observe、follow。我们一个一个来对比，先看第一个。 29 00:08:26,640 --> 00:08:33,200 Dean：OK, what is the first synonym? How should I use it correctly? 30 00:08:33,700 --> 00:08:58,820 茉莉：第一个是 comply。它的意思是“遵从、照做”，更强调“对要求或命令的回应”。适用场景通常是正式要求、指令、法律或政策，例如 comply with a rule 或 comply with an order。语气上比 conform 更偏“服从指令”。例句：You must comply with the safety instructions. 31 00:08:59,320 --> 00:09:03,640 Dean：Great. What about the next synonym? How is it different? 32 00:09:04,140 --> 00:09:26,220 茉莉：第二个是 adhere。它的意思是“坚持遵守”，更强调“牢牢地不放开”，也常用于规则、原则、标准。适用场景里它比 comply 更像“保持一致、保持原则”，语气更稳、更正式。例句：The team should adhere to the official guidelines. 33 00:09:26,720 --> 00:09:29,760 Dean：Good. What about the third synonym? 34 00:09:30,260 --> 00:09:52,660 茉莉：第三个是 observe。它的意思是“遵守（规章）”，常用于正式场合，语气有“遵规的礼貌感”。注意它和 observe 还有“观察”的意思，所以在句子里通常要配套宾语，比如 observe rules。例句：Visitors must observe the building rules. 35 00:09:53,160 --> 00:09:56,040 Dean：What about the fourth synonym? 36 00:09:56,540 --> 00:10:16,060 茉莉：第四个是 follow。它的意思是“按……去做”，最通用，也最口语友好。适用场景里 follow 常用于日常指令和步骤，语气通常比 conform 更轻，也更容易用于简单的行动建议。例句：Please follow the instructions carefully. 37 00:10:16,560 --> 00:10:20,240 Dean：Can you summarize when to use which word? 38 00:10:20,740 --> 00:10:45,379 茉莉：总结一下：如果你想强调“回应要求、执行命令”，用 comply；如果你想强调“坚持不偏离”，用 adhere；如果是更正式、带点“遵规”的语气，用 observe；如果是最普通、最日常的“按着做”，用 follow。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:10:45,879 --> 00:10:54,519 Dean：We have learned so much. Now let’s relax with a fun short story related to conform. 40 00:10:55,019 --> 00:10:56,460 茉莉：什么故事？ 41 00:10:56,960 --> 00:11:12,800 Dean：Last Monday, I went to school for a parent meeting. I was nervous. The teacher said, “Please conform to the school regulations.” I nodded and smiled like a perfect student. Then I took my seat. 42 00:11:13,300 --> 00:11:17,460 茉莉：你当时是不是很紧张？然后发生了什么？ 43 00:11:17,960 --> 00:11:40,680 Dean：After ten minutes, another teacher walked in with a big clipboard. She said, “Visitors should conform to the dress code.” My T-shirt had a cartoon on it. It was cute, but it was not “official.” So I tried to fix it quickly. I put on a jacket… and the jacket said, “I love pizza” in big letters. 44 00:11:41,180 --> 00:11:45,820 茉莉：哈哈，听起来更糟了！后来老师怎么说？你是怎么继续的？ 45 00:11:46,320 --> 00:12:10,800 Dean：The teacher looked at my jacket, then at her clipboard. She sighed and said, “Okay… you conform to the rules in a creative way.” Then she added, “Just do not conform to pizza culture during exams.” Everyone laughed, and I finally felt relaxed. At the end, I waved and said, “Thank you. I will comply next time!” 46 00:12:11,300 --> 00:12:33,060 茉莉：原来关键是：你用 conform 表达“遵守规定”，还在不同场景里用了它的搭配，比如 conform to the school regulations 和 conform to the dress code。最后用 comply 做了个呼应，整个笑点就是“越想符合越有创意”，对吧？ 47 00:12:33,560 --> 00:12:57,560 Dean：Yes! Today we practiced conform with different meanings: follow rules, fit in, and be in line with expectations. We used real situations like safety gear, school rules, and legal checks. And remember the story: when you try too hard to conform, you might end up conforming in a funny way. Thanks for listening. See you next time!

1 00:00:00,000 --> 00:00:17,280 Dean：Hi everyone. Today we learn the word “scissors.” Scissors are a tool with two blades you use to cut paper or cloth. It can also mean “two cutting blades used together.” Moli, how do you understand it in Chinese? 2 00:00:17,780 --> 00:00:29,140 茉莉：“Scissors” 指的是剪刀，用来把纸、布料等材料剪开。对应的英文可以说：a tool for cutting. 这是什么词性？通常怎么用？ 3 00:00:29,640 --> 00:00:40,200 Dean：“Scissors” is a noun. We usually use it for one item in the plural form: scissors. Now we learn with an example sentence: “I need scissors to cut this paper.” 4 00:00:40,700 --> 00:00:56,380 茉莉：例句是在说：你要用剪刀把这张纸剪开。这里的用法很常见，就是说自己“需要剪刀”来做剪切动作。Moli想让 Dean 用更简单的英文解释一下这句话是什么意思。 5 00:00:56,880 --> 00:01:09,200 Dean：It means you want a pair of scissors to cut the paper. It is simple and common in daily life. Next example: “The teacher brought scissors for the art class.” 6 00:01:09,700 --> 00:01:23,460 茉莉：这句话的意思是：老师为美术课带来了剪刀。这里的“art class”表示课堂活动场景，scissors用来做手工或剪贴。请继续讲下一个例句。 7 00:01:23,960 --> 00:01:35,000 Dean：This means scissors are used in class for making things. It sounds natural for school. Example 3: “Be careful with scissors. They can hurt you.” 8 00:01:35,500 --> 00:01:47,500 茉莉：这句话是在提醒：使用剪刀要小心，因为它可能会伤到你。这里强调安全注意事项。接下来我们讲词根词缀与词源。 9 00:01:48,000 --> 00:01:58,719 Dean：Let’s dig a little deeper. What are the word root parts and any affixes in “scissors”? And how did the word history shape its meaning? 10 00:01:59,219 --> 00:02:59,219 茉莉：好，那我们就像拆玩具一样来拆“scissors”。你会发现它看起来像一个复数形式的东西，但它其实是用来表示“一对剪刀”这种工具的。词源上，它来自英语里旧的说法和更早期的日耳曼语根，和“切、剪”这一类动作有关。后来语言慢慢把这种“成对的切割东西”的用法固定下来，所以你会看到它几乎总是用复数的样子：scissors。至于长得像的亲戚词，我们可以顺口提一下“science”这种不太相关但同样来自拉丁语体系、容易让人误会的词；它看起来也很“像”，但意思和切割没有直接关系。更贴近“切”这个方向的词，像“dissection”那类词，虽然更学术，但它也有“把东西切开检查”的感觉，只是它强调的不是“剪刀”这个工具，而是动作和过程。 11 00:02:59,719 --> 00:03:08,199 Dean：Interesting! So what did the word originally mean, and how did it become the “tool with two blades” idea we use today? 12 00:03:08,699 --> 00:04:11,899 茉莉：我来讲个小故事。很久以前，人们说“切开”的概念时，并不是先想到一个现代的英语名词，而是先有“用来切”的意思，尤其是那种需要双手配合、两边同时起作用的工具。随着工具越来越固定，语言也越来越爱省事，于是人们开始用一种带有“成套、成对”感觉的说法来指代这件东西。慢慢地，表示“剪”的那部分意义和“两个刃”的画面融合在一起，大家听到这个词就会自动想到两片刀刃夹在中间的动作。到今天，这个词几乎只在“那种剪东西的工具”这个意义上活着，而且它的外形也保留了“成对”的传统，所以我们说 a pair of scissors，或者直接用 scissors 来表示这套东西。最有意思的是，它不是随便变成复数的，而是它背后一直就带着“两片刃、一起用”的感觉。下一部分我们可以讲搭配、常见场景和怎么在对话里自然互动。 13 00:04:12,399 --> 00:04:28,719 Dean：Imagine you are at home, and you need to open a big package. You cannot tear the tape well, so you take a small pair of scissors. In this situation, what collocations can we use with “scissors”? 14 00:04:29,219 --> 00:04:48,259 茉莉：第一个很常用的搭配是“a pair of scissors”。语感上它强调“一套剪刀”，也就是通常那两把刀刃是一组的。中文里我们说“把剪刀”，英文里一般就说“a pair of scissors”，而不是直接说一把一把的那种感觉。 15 00:04:48,759 --> 00:04:54,199 Dean：In my example, I say: “I need a pair of scissors to open this box.” 16 00:04:54,699 --> 00:05:06,539 茉莉：这句话很自然。因为日常生活里我们通常不会数“单把刀”，而是把剪刀当成“一对/一套工具”来用，所以用“a pair of scissors”很对。 17 00:05:07,039 --> 00:05:20,639 Dean：Now think about school. You are in an art class, and the teacher says you must use scissors carefully. What do we usually say in this kind of scene, and how do we connect it with “scissors”? 18 00:05:21,139 --> 00:05:36,180 茉莉：第二个搭配是“be careful with scissors”。它是一种安全提醒，语气很像老师或家长说的“注意点”。你会经常在学校和活动场景听到，重点是提醒你不要乱挥或随便对着人。 19 00:05:36,680 --> 00:05:41,480 Dean：Example sentence: “Be careful with scissors. They are sharp.” 20 00:05:41,980 --> 00:05:51,580 茉莉：对，这里用“sharp”就是在强调危险点。整句话的语气很符合课堂提醒，所以搭配非常常见、也很地道。 21 00:05:52,080 --> 00:06:03,440 Dean：Third, picture a busy office or workplace. You are making a small display or a poster, and you quickly cut some paper. What would sound natural here? 22 00:06:03,940 --> 00:06:18,820 茉莉：第三个搭配是“cut with scissors”。它更直接，就是用“剪刀”来做“剪”的动作。相对说法里，“用剪刀剪”在英文里通常就用 cut with scissors，表达清楚，不绕。 23 00:06:19,320 --> 00:06:24,440 Dean：In a short example: “I will cut the paper with scissors.” 24 00:06:24,940 --> 00:06:36,940 茉莉：这个用法很自然，特别是在做手工、剪贴、做展示的时候。注意它是强调“用剪刀完成动作”，所以用 with 很关键。 25 00:06:37,440 --> 00:06:57,280 Dean：Time for an interaction question for everyone listening. Here is a choice: when you warn someone, which one is more natural? A) “Be careful scissors.” B) “Be careful with scissors.” Think and answer, then try to make one more simple sentence using the same pattern. 26 00:06:57,780 --> 00:07:19,860 茉莉：来复述一下互动问题：我们要选出更自然的提醒用法，重点是警告别人“用剪刀要小心”。答题要点是：英文里这里一定要有 with，构成固定搭配 be careful with scissors。接下来我也想带大家了解一下，这个词和它的近义词在用法和语感上有什么区别。 27 00:07:20,360 --> 00:07:25,800 Dean：What are some common synonyms of “scissors”? How are they different in usage? 28 00:07:26,300 --> 00:07:36,060 茉莉：“Scissors” 常见近义词可以说：shears、cutters、snips、trimmers、paring knife。我们一个一个来对比，先看第一个。 29 00:07:36,560 --> 00:07:41,040 Dean：OK, what is the first synonym? How should I use it correctly? 30 00:07:41,540 --> 00:08:07,460 茉莉：第一个近义词是 shears。它和 scissors 的核心意思都和“剪切”有关，但 shears 通常更偏“大一点、更有力量的剪刀”，有时也用于园艺或剪金属的场景，所以常常更强调用途和工具的强度。日常剪纸也能用，但不如 scissors 那么通用。例句：The gardener used shears to cut the bushes. 31 00:08:07,960 --> 00:08:12,760 Dean：Got it. What about the next synonym? How is it different? 32 00:08:13,260 --> 00:08:36,620 茉莉：第二个近义词是 cutters。cutters 更像“切割工具/剪切工具”的总称，有时也特指用来切特定材料的工具，不一定是普通的家用剪刀。它的感觉更偏工具功能，而不是“一个固定形状的剪刀”。常见于专业或描述材料加工的语境。例句：The package had plastic cutters for opening the seal. 33 00:08:37,120 --> 00:08:40,480 Dean：Thanks. What is the third synonym? 34 00:08:40,980 --> 00:09:04,019 茉莉：第三个近义词是 snips。snips 指“小剪刀”或“短促快速剪”的感觉，语气更轻便、更随手，常见于剪线头、修小东西，或者强调快速、少量的剪。它通常不用于你要剪一大张纸那种场景。例句：Use these snips to cut the string. 35 00:09:04,519 --> 00:09:08,519 Dean：OK. Can you ask about the fourth synonym? 36 00:09:09,019 --> 00:09:29,659 茉莉：第四个近义词是 trimmers。trimmers 更强调“修剪、修整”的用途，所以它常用于修边、整理形状，比如修指甲边缘、修草、修材料边角。它不等同于通用的剪纸剪布的工具。例句：I need a trimmer to tidy the edges of the fabric. 37 00:09:30,159 --> 00:09:34,480 Dean：Great. Can you summarize when to use which word? 38 00:09:34,980 --> 00:10:06,500 茉莉：总结一下：想说日常“用剪刀剪纸、剪布”这种最通用的词，用 scissors 最稳。要强调更有力量、偏专业或园艺用的大剪切工具，用 shears。要强调切割工具的功能或偏专业场景，用 cutters。想表达轻便小剪、快速剪一点点，用 snips。要强调“修剪、修整边缘”的目的，用 trimmers。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:10:07,000 --> 00:10:15,320 Dean：We have learned so much today. Now let’s relax with a fun short story about “scissors.” 40 00:10:15,820 --> 00:10:19,500 茉莉：什么故事？我已经有点期待了。 41 00:10:20,000 --> 00:10:47,360 Dean：It is Monday morning. I am at the office. I need to open a big box for a meeting poster. But the tape is strong. So I grab a pair of scissors from the drawer. I say, “Be careful with scissors!” to myself, because I do not want to cut my finger. Then I cut the tape. The box opens… kind of. 42 00:10:47,860 --> 00:10:51,700 茉莉：哎？怎么会“kind of”？然后呢？ 43 00:10:52,200 --> 00:11:26,759 Dean：Inside, there is a smaller box. The poster is folded neatly, but there is also a note. The note says, “Do not use scissors. Use patience.” So I say, “Oh no.” I look at the note again. Then my boss walks in and sees me holding the scissors. My boss says, “Are you making art again?” I tell him, “No, I’m just opening the package.” My boss smiles and says, “Great. Cut the tape… and also cut the excuse.” 44 00:11:27,259 --> 00:11:42,620 茉莉：哈哈！这真是办公室经典笑点。这个故事里，“scissors”的关键用法其实有两点：第一是用 a pair of scissors 表示“一套剪刀”；第二是用 be careful with scissors 来做安全提醒。 45 00:11:43,120 --> 00:11:57,840 Dean：Yes! And we also used scissors to cut the tape when we needed action. At the end, I finally opened the box, put the poster up, and promised to use more patience next time. Thanks for listening, everyone. See you next time, and stay safe with your scissors!

1 00:00:00,000 --> 00:00:16,000 Dean：Today we are learning the word “ample.” It means “enough or more than enough.” For example, “There is ample time.” You can also say, “There is plenty of time.” Moli, how do you understand it in Chinese? 2 00:00:16,500 --> 00:00:29,140 茉莉：“ample”表示“充足的；足够的（而且通常是绰绰有余）”。英文对应可以是“more than enough.” 这个词是什么词性，常怎么用？ 3 00:00:29,640 --> 00:00:43,719 Dean：It is an adjective. We use it for things like time, space, or money. We often say “ample + noun.” Let’s use one example to learn it. “There was ample time to finish the test.” 4 00:00:44,219 --> 00:00:58,619 茉莉：这句话的意思是：考试开始后，时间很充裕，所以学生有足够的时间完成试卷。这里的 “ample” 就是“足够而且有余”。请你用更简单的英文再解释这句。 5 00:00:59,119 --> 00:01:09,840 Dean：In this sentence, “ample time” means “a lot of time,” not just a little. It also sounds reassuring. “I had ample space in my bag.” 6 00:01:10,340 --> 00:01:23,620 茉莉：这句话的意思是：我包里有很大的空间。这里强调的是“空间足够，还很宽松”，所以不用担心塞不下。请英文讲者继续用更简单的方式讲它的语感。 7 00:01:24,120 --> 00:01:32,920 Dean：“ample space” means there is enough room for your things. It sounds positive and easy. “We have ample food for the party.” 8 00:01:33,420 --> 00:01:49,260 茉莉：这句话的意思是：派对上我们准备了足够的食物，可能还会有多的。这里 “ample” 用来表达“充足”。接下来我们讲词根词缀与词源。 9 00:01:49,760 --> 00:02:01,280 Dean：What are the word roots, affixes, and the etymology of “ample”? Where does it come from, and how did it get to mean “enough or more than enough”? 10 00:02:01,780 --> 00:03:13,620 茉莉：好，那我们来把 ample 拆开想一想。它看起来像一个整体，但它的“家族”其实和拉丁语那边的词根有关系。先说它今天的感觉：ample 给人的印象是“空间很开、数量也很足”，所以它常常和 time space food 这种可计量的东西一起出现。至于词根词缀方面，我们可以把它理解成“来自古代拉丁语的词形演变”，而不是像很多现代英语那样一眼就能看出明显前后缀。词源里它和 “扩展、伸展、变得宽裕” 这类意思很接近，所以才会从“伸展开来、充足富余”慢慢变成今天的“enough, and even more.” 说到同族词的亲戚关系，你会在一些词里看到类似的意味，比如 ample 旁边经常出现的相关词 stemmed from the same older language family，比如 amplitude 这种表示“幅度、量的范围”的词。它不直接等于 ample，但都在表达“量不小、范围不窄”。还有一个你可能会听过的词：amplify，意思是“扩大、增强”。它的感觉就是把东西“往更大范围推开”，和 ample 的“够用而且很宽裕”是一种同方向的想法。 11 00:03:14,120 --> 00:03:30,439 Dean：So what did this word originally mean? How did the meaning change over time? 12 00:03:30,939 --> 00:04:44,860 茉莉：好像是一段小旅行：在更早的拉丁语里，有一类词和 “扩展、增加、让范围变大” 有关系。起初重点不一定是“时间够不够”，而是“量能不能被拉开、空间能不能变得更宽”。后来这些意思逐渐走到英语里，就变成了对“充足”的表达方式：当你有足够的量、足够的空间，甚至比你需要的还多，就会用 ample 这种词来形容。于是它的语气也会变得很积极：不是那种紧巴巴的够用，而是带着放心感的“很宽裕”。 而且你看，amplitude 和 amplify 都在做同一件事：把“范围”往外推，把“量”往上放。所以等你真正理解了那条线，你会发现 ample 其实不是突然冒出来的，而是从“扩展、变得宽裕”慢慢走到“enough or more than enough”。我觉得最有趣的是，它现在看起来只是一个很日常的形容词，但背后却有一条“从扩展到宽裕”的故事线。下一部分我们就讲它常见的搭配、在什么场景里说起来最自然，以及怎么和别人互动使用。 13 00:04:45,360 --> 00:04:58,319 Dean：Imagine you are running late for school, but then your phone shows the bus is delayed. You look at the clock and feel better. In this situation, how would we use this word? 14 00:04:58,819 --> 00:05:18,819 茉莉：第一个很常见的搭配是 ample time。它的语气比 just enough 更放松、更安心，强调“时间够用，而且还有余地”，所以你不太需要赶、也不用太担心来不及。你可以在上课、赶车、考试前那种“突然发现还有时间”的时刻用。 15 00:05:19,319 --> 00:05:27,159 Dean：You can say: “I have ample time to get ready.” It means you have a lot of time, not only a little. 16 00:05:27,659 --> 00:05:38,219 茉莉：这句话在日常口语里很自然，特别是在你临时发现不用慌的时候。ample 让人感觉事情会顺利，因为时间不是紧绷的状态。 17 00:05:38,719 --> 00:05:54,559 Dean：Now think about a work meeting. You are planning a project, and your manager says the budget is not a problem. You feel calmer, because you can buy what you need. In this kind of meeting, how do we use “ample”? 18 00:05:55,059 --> 00:06:14,739 茉莉：第二个搭配是 ample budget。budget 是可量化的东西，用 ample 会让人觉得资源很充足，不是“勉强够”，而是“够用而且更宽裕”。在工作场景里，这个搭配常常带来积极的气氛，比如让团队知道可以按计划做得更好。 19 00:06:15,239 --> 00:06:23,079 Dean：For example: “We have an ample budget for the software.” It means the money is enough, and maybe more than we need. 20 00:06:23,579 --> 00:06:34,139 茉莉：用在工作里会比较地道。你如果想表达“老板给的资源很充足”，ample budget 就很合适；它不像 low budget 那样有压力。 21 00:06:34,639 --> 00:06:48,719 Dean：Third, imagine you are hosting a small birthday party at home. You bought snacks, drinks, and some extra food. Your friend asks, “Will we have enough?” You want to sound confident. What would you say here? 22 00:06:49,219 --> 00:07:03,939 茉莉：第三个搭配是 ample food。它强调食物准备得很充分，通常也暗示“不用担心不够”，甚至可能还有剩。适合你在社交场合想让别人放心、表现你做了充分准备的时候用。 23 00:07:04,439 --> 00:07:10,999 Dean：You can say: “We have ample food for everyone.” It means everyone will be able to eat. 24 00:07:11,499 --> 00:07:23,339 茉莉：这在聚会聊天里很自然，而且语感上更像“大家放心，我准备好了”。比起只说 enough，它更有“富余”的感觉。 25 00:07:23,839 --> 00:07:51,839 Dean：One more quick scene for listeners. Imagine a school club. The teacher allows you to study in the library, and you can ask questions whenever you want. You want to ask for more time in a polite way. Which is more natural? A) “We have ample chance to ask questions.” B) “We have plenty of chance to ask questions.” Choose A or B, and make one sentence like your own. What will you pick? 26 00:07:52,339 --> 00:08:19,059 茉莉：互动题：大家要选 A 或 B，并造一个包含这个词义的句子。答题要点是看搭配是否地道：在这种“有机会/有条件做某事”的语境里，用 more than enough 的感觉去表达“机会充足”，并且句子要自然、简单。接下来我们就想了解这个词和它的近义表达，具体有什么细微区别。 27 00:08:19,559 --> 00:08:25,319 Dean：What are some common synonyms of “ample”? How are they different in usage? 28 00:08:25,819 --> 00:08:33,659 茉莉：常见近义词有 plenty, enough, satisfactory, and generous。我们一个一个来对比，先看第一个。 29 00:08:34,159 --> 00:08:39,439 Dean：OK, what is the first synonym? How should I use it correctly? 30 00:08:39,939 --> 00:09:10,179 茉莉：plenty。含义上和 ample 很接近，都表示“很多、足够”。但 ample 更强调“充足而且通常还很宽松”，听起来更正式、更安心；plenty 更日常、更口语，也更常和不可数名词搭配。适用场景上，时间、食物、资源这类你“觉得够用甚至很多”的情况都可以用 plenty。例句：We have plenty of time to finish. 31 00:09:10,679 --> 00:09:14,839 Dean：Good. What about the next synonym? How is it different? 32 00:09:15,339 --> 00:09:36,299 茉莉：enough。含义上是“足够”，但它不一定带“还有余”的感觉。ample 往往让人觉得更宽裕、更放心；enough 只是说不会缺。适用场景上，回答“够不够”最常用 enough，比 ample 更中性。例句：Is there enough food for everyone? 33 00:09:36,799 --> 00:09:40,159 Dean：Thanks. What about the third synonym? 34 00:09:40,659 --> 00:10:08,500 茉莉：satisfactory。含义上是“令人满意的、达标的”，更偏结果评价，不是强调数量有多大。ample 是从“资源/空间/时间够多”出发；satisfactory 是从“质量或效果是否达标”出发。适用场景上，考试成绩、服务质量、计划是否可接受更常用 satisfactory。例句：The service was satisfactory. 35 00:10:09,000 --> 00:10:12,519 Dean：Okay. Any fourth synonym? What is it like? 36 00:10:13,019 --> 00:10:38,299 茉莉：generous。含义上是“慷慨的，给得很多的”，所以它带有人对你“愿意提供更多”的感觉。ample 主要强调“数量充足、条件宽松”，不一定有人情或态度。适用场景上，当你想夸奖对方给了超出预期的支持或分量时更合适用 generous。例句：Her generous offer saved me a lot of money. 37 00:10:38,799 --> 00:10:42,639 Dean：Can you summarize when to use which word? 38 00:10:43,139 --> 00:11:14,819 茉莉：总结一下：想表达“足够而且通常还有余、让人很放心”，用 ample；想更口语地说“很多、够用”，用 plenty；只回答“够不够”，用 enough；当你评估“结果是否达标”，用 satisfactory；当你强调“对方给得很多、带有慷慨或善意”，用 generous。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:11:15,319 --> 00:11:22,679 Dean：We have learned so much. Now let’s relax with a fun short story related to “ample.” 40 00:11:23,179 --> 00:11:24,779 茉莉：什么故事？ 41 00:11:25,279 --> 00:11:40,000 Dean：I was at school with my friend for a club meeting. The teacher said, “Don’t worry. You have ample time to finish the poster.” So I started eating snacks. I was like, “Perfect. I am calm!” 42 00:11:40,500 --> 00:11:45,940 茉莉：你先吃零食了？那老师真的给了足够的时间吗？ 43 00:11:46,440 --> 00:12:04,200 Dean：Yes, but then my phone rang. My friend shouted, “Your picture is still not downloaded!” I ran to the table and looked at my bag. Then I said, “Wait… I have ample space in my bag.” So I put the whole poster in my bag, like it was snacks. 44 00:12:04,700 --> 00:12:11,740 茉莉：哈哈，你把海报塞进包里了？这听起来也太“宽裕”了吧！ 45 00:12:12,240 --> 00:12:30,000 Dean：Then the twist happened. The bag was “ample space,” yes. But my teacher opened it and said, “Nice plan. Now… where is the food?” I answered, “Teacher, I had ample food too. I just shared it with the poster.” 46 00:12:30,500 --> 00:12:45,700 茉莉：原来你准备得太充分，充分到把东西放反了！这个故事里，“ample time”和“ample space/ample food”都是在表达“很充足、让人不担心”，而且语气听起来很轻松、自信。 47 00:12:46,200 --> 00:13:06,680 Dean：Today we learned that “ample” means “enough or more than enough.” We practiced common uses like ample time, ample budget, ample food, and ample space. And remember, if you feel calm, you might use “ample”… and if you’re careless, your teacher might still laugh. See you next time!

1 00:00:00,000 --> 00:00:13,759 Dean：Hello everyone. Today we study the word actor. An actor is a person who acts in plays or movies. It is someone who performs a role. Moli, how do you understand this word in Chinese? 2 00:00:14,259 --> 00:00:38,579 茉莉：“actor”表示“演员”，通常指在戏剧或电影里扮演角色的人。英文里也可以理解为“someone who performs a role”（不超过8个词）。 这个词是什么词性？它一般是名词，用在“an actor / actors”里，也常和“play、movie、role”这类词搭配使用。你觉得它更像“职业”还是“身份”呢？ 3 00:00:39,079 --> 00:00:56,359 Dean：actor is a noun. We usually say an actor or actors. We use it for people in movies, TV, and stage plays. Now, let’s use an example to learn. Example 1: He is a famous actor in a new movie. 4 00:00:56,859 --> 00:01:14,780 茉莉：这句话的意思是：他是新电影里很有名的一位演员。 这里没有特别难的词，但“famous”表示“出名的”，“new movie”就是“新上映的电影”。 Dean, can you explain the feeling of this sentence in simpler English? 5 00:01:15,280 --> 00:01:27,599 Dean：It sounds like we are talking about his job and his fame. It also tells us he works in films. Example 2: The actor practiced every day before the show. 6 00:01:28,099 --> 00:01:43,139 茉莉：这句话的意思是：在演出之前，这位演员每天都在练习。 这里的“practiced”是动词，表示反复练习，为了让表演更好。 Dean, please continue with the next sentence in simpler English. 7 00:01:43,639 --> 00:01:56,439 Dean：The word actor here is about stage work, like a theater show. It shows effort before acting. Example 3: My sister wants to be an actor one day. 8 00:01:56,939 --> 00:02:11,339 茉莉：这句话的意思是：我妹妹有一天想成为一名演员。 这里的“wants to be”表示“想要成为”，是一个表达愿望的结构。 接下来我们讲词根词缀与词源。 9 00:02:11,839 --> 00:02:17,759 Dean：What are the word roots, affixes, and the etymology of actor? 10 00:02:18,259 --> 00:03:10,099 茉莉：我们先从这个词怎么“拼出来”的感觉聊起。actor 看起来很简单，但它的核心其实来自拉丁语的一条路：在拉丁语里有一个动词 agere，意思跟“做、驱动、行动”很接近。后来在英语的来源里，它慢慢就和 “act” 这条线连在一起了。你会发现，actor 里面的意思不是“说话的人”，而是“做表演动作的人”，所以它天然更贴近“行动、表演”。同族词方面，你可以想到 act、action、active 这些都来自同一条“做事情/行动”的家族；其中 act 更像动词或核心概念，action 更强调“行动过程”，active 则偏向形容词，表示“积极参与的”。而 actor 就更明确：把这些“行动”的概念落到人身上，就是“表演的人”。 11 00:03:10,599 --> 00:03:15,879 Dean：So what did this word originally mean? How did the meaning change over time? 12 00:03:16,379 --> 00:04:16,859 茉莉：好，我们把它当成一个小故事来听：很久以前，拉丁语的 agere 一直在讲“行动、驱动、把事情往前推”的那种力量。后来，当欧洲的戏剧文化发展起来，人们需要一个词来指“在舞台上真正做出表演的人”。于是在拉丁语传统里，act 的相关说法逐渐固定下来，指向“承担表演的人”。到中世纪和近代英语时期，actor 变得更常用，含义也就更稳定了：不只是任何“做事的人”，而是特指在戏剧、电影、电视里扮演角色并进行表演的人。你看，它的意思其实一步步变得更具体，从“行动”走向“表演”，最后落到“演员”。我觉得最有趣的是：它和 act、action 这些词其实是同一个“行动”的家族，只是一个说的是动作，一个说的是动作的过程，而 actor 直接说的是“做动作的人”。下一部分我们会讲搭配、场景与互动。 13 00:04:17,359 --> 00:04:28,399 Dean：Imagine you go to a small theater for a school show. After the show, you see him again and you want to praise him. What word do we use with actor in this situation? 14 00:04:28,899 --> 00:04:49,060 茉莉：第一个搭配是 actor in a play。语感上很自然，适合讲“在一出戏里演出/出演”的关系。这里的 in 表示“在……之中（扮演/参与）”，play 就是舞台戏剧。你可以把它当成说“某个演员在某个剧里演了什么”的常用说法。 15 00:04:49,560 --> 00:04:58,839 Dean：Use: actor in a play. Example: He is an actor in a play at our school. 16 00:04:59,339 --> 00:05:12,619 茉莉：这句话里把“演员”和“戏剧作品”直接连在一起，信息很清楚，也很常见。更具体一点时，你还可以在后面加角色名，比如 play 的名字或他演的角色。 17 00:05:13,119 --> 00:05:23,199 Dean：Now think about work. You watch a TV show, and you want to talk about who acted in it. In this case, how do we use actor with the show? 18 00:05:23,699 --> 00:05:43,699 茉莉：第二个搭配是 actor in a TV series。它特别适合新闻、影评、日常聊天里，说“某位演员出演某部电视剧/剧集”。series 是“连续剧”的意思，和 single episode 不一样；你用 actor in a TV series，就等于在说“在这种连续剧里有他”。 19 00:05:44,199 --> 00:05:50,119 Dean：Use: actor in a TV series. Example: She is an actor in a TV series. 20 00:05:50,619 --> 00:06:00,539 茉莉：这个搭配很地道，尤其在介绍某人最近的作品时。注意 series 通常是指整部剧，不只是一集。 21 00:06:01,039 --> 00:06:13,199 Dean：Let’s move to a social setting. You are at a party and someone asks about your favorite movie. You want to say who was in it. What do we say with actor here? 22 00:06:13,699 --> 00:06:30,980 茉莉：第三个搭配是 actor in a movie。它最直接，适合日常聊天，也适合短评里快速表达“这部电影里有哪位演员”。movie 就是泛指电影，不需要再强调是新片还是老片，听的人也能明白你在讲哪部。 23 00:06:31,480 --> 00:06:35,319 Dean：Use: actor in a movie. Example: He is an actor in a movie I like. 24 00:06:35,819 --> 00:06:44,620 茉莉：自然，而且很常用。你可以根据语境加上电影名，比如 “in the movie …” 来让信息更完整。 25 00:06:45,120 --> 00:07:01,439 Dean：Before we finish, I have a question for you. Listen carefully: When you talk about a person who plays in a theater show, do you say “actor in a play” or “actor in a movie”? Choose the more natural one, and make one short sentence with your choice. 26 00:07:01,939 --> 00:07:07,219 Dean：What are some common synonyms of “actor”? How are they different in usage? 27 00:07:07,719 --> 00:07:18,439 茉莉：“actor”常见的近义词有：performer、thespian、star、artist、cast member。我们一个一个来对比，先看第一个。 28 00:07:18,939 --> 00:07:24,060 Dean：OK, what is the first synonym? How should I use it correctly? 29 00:07:24,560 --> 00:07:59,920 茉莉：performer。它和 actor 都指“在舞台或屏幕上表演的人”，但含义更广：performer 可以是演员，也可以是歌手、舞者或其他表演者，不一定专指“扮演角色”。更适合日常聊天或泛指某类表演者；语气通常很中性。搭配上一般说 a live performer、a show performer，而不一定像 actor 那样常和 play、movie、TV series 精确绑定。例句：He is a talented performer at the theater. 也可以说：The performer sang a song during the show. 30 00:08:00,420 --> 00:08:04,100 Dean：Got it. What about the next synonym? How is it different? 31 00:08:04,600 --> 00:08:21,560 茉莉：thespian。它指“戏剧演员”，更偏正式或文艺风格，有时带一点“戏剧圈”的感觉，但不太适合日常普通对话。搭配上常见的是 a famous thespian。例句：She is a famous thespian in local theater. 32 00:08:22,060 --> 00:08:24,939 Dean：Thanks. What is the third synonym? 33 00:08:25,439 --> 00:08:50,240 茉莉：star。star 更强调“受欢迎或很出名的演员”，所以语气通常更偏“明星感”，不只是职业身份。它常用于电影或电视剧的宣传语境，也常见于媒体报道和影评。搭配上更常说 a movie star、a TV star，而不如 actor 那样中性地描述“扮演角色的人”。例句：He is a star in the new movie. 34 00:08:50,740 --> 00:08:55,379 Dean：Do we have another one? Can you tell me the next synonym? 35 00:08:55,879 --> 00:09:21,960 茉莉：artist。artist 比较宽泛，可以指表演艺术家，但也可以指画家、音乐家等创作者；因此它不如 actor 精确。更适合正式一点的概括，比如艺术界或“艺术家”的讨论。搭配上常见 a theater artist，但一般不如 actor 常用得多。例句：She is a theater artist and a good singer too. 36 00:09:22,460 --> 00:09:26,620 Dean：Great. Can you summarize when to use which word? 37 00:09:27,120 --> 00:10:01,680 茉莉：总结一下：如果你想准确表达“在电影、电视剧或戏剧里扮演角色的演员”，最自然用 actor，并且配合 play、movie、TV series。要更泛指“表演者”，用 performer。要强调“戏剧圈的演员”，用 thespian，但别太随便用在日常。要突出“名气和明星属性”，用 star。要更宽泛地说“艺术家”，用 artist，但注意它不只限演员。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 38 00:10:02,180 --> 00:10:09,860 Dean：We have learned so much. Now let’s relax with a fun short story about actor. 39 00:10:10,360 --> 00:10:11,960 茉莉：什么故事？ 40 00:10:12,460 --> 00:10:26,060 Dean：Yesterday after school, I joined a club meeting. Our teacher said, “We need an actor for the small play.” I said, “I can do it.” But then Moli, you know what happened. 41 00:10:26,560 --> 00:10:33,440 茉莉：我知道！接下来他是不是很尴尬？比如站错地方，或者台词忘了？ 42 00:10:33,940 --> 00:10:58,900 Dean：Yes! On the first day, I had a job: be an actor in a play. I practiced my lines every day. “Hello, I am the hero!” But at the show, the microphone was not working. So I shouted louder: “Hello, I am the hero!” Everyone heard me, but the teacher thought I was an actor in a TV series. 43 00:10:59,400 --> 00:11:04,520 茉莉：哈哈，老师把他当成“拍剧”的了？那他怎么解释才对？ 44 00:11:05,020 --> 00:11:22,140 Dean：I tried to fix it. I said, “No, teacher. I am an actor in a play.” Then she nodded and said, “Great! Please act like you are on TV.” So I started waving like a movie star. The audience clapped, and my lines did not even matter. 45 00:11:22,640 --> 00:11:41,680 茉莉：这个故事太好笑了！总结一下：在这类场景里，我们会用 actor in a play 表达“在戏剧里演”，用 actor in a TV series 表达“在连续剧里出演”，而在派对或日常聊天时，也可以用 actor in a movie 很自然。 46 00:11:42,180 --> 00:11:55,300 Dean：Today we learned actor is a noun, and we used it in real life with play, TV series, and movie. Great job, everyone. See you next time, and keep practicing with confidence!

1 00:00:00,000 --> 00:00:16,960 Dean：Today we learn the word taxi. A taxi is a car you hire to travel around a city. It is also a kind of vehicle for paid trips. A simpler way to say it is: a paid car for city travel. Moli, how do you understand taxi in Chinese? 2 00:00:17,460 --> 00:00:30,579 茉莉：taxi 指的是“出租车”，也就是你付钱后用来载你去某个地方的车。英文对应可以是 hired car. 接下来这个词是什么词性？常怎么用？ 3 00:00:31,079 --> 00:00:44,839 Dean：Taxi is a noun. It is very common for city travel. We also use it with “a” or “take.” Let’s use examples to learn. Example 1: “I called a taxi to the airport.” 4 00:00:45,339 --> 00:00:57,500 茉莉：这句话的意思是：我给机场叫了一辆出租车，想去机场。这里的难点是 taxi，表示“出租车”。如果你要用更简单的英文，你可以怎么说？ 5 00:00:58,000 --> 00:01:09,519 Dean：In this sentence, taxi means the car service you book by phone. We use “called a taxi” for ordering it. Example 2: “The taxi driver helped us with our bags.” 6 00:01:10,019 --> 00:01:23,780 茉莉：这句话发生在出门或旅行时：出租车司机帮我们拿行李。这里 taxi 还是指出租车及其司机。再请你用更简单的英文解释这句的意思。 7 00:01:24,280 --> 00:01:37,079 Dean：Here, we see the taxi driver as the person who drives the taxi. It shows a normal, daily situation. Example 3: “We stopped at the taxi stand after dinner.” 8 00:01:37,579 --> 00:01:51,980 茉莉：这句话的意思是：晚饭后我们在出租车站停下来等车。这里的难点是 taxi stand，指的是“出租车等候的地方”。接下来，我们讲词根词缀与词源。 9 00:01:52,480 --> 00:01:59,200 Dean：What are the word roots, affixes, and the etymology of taxi? 10 00:01:59,700 --> 00:03:01,780 茉莉：taxi 这个词我来讲个“拼出来”的故事。它看起来像是一个整体，但它其实和法语以及更早的语言有关系。在英语里你会觉得它很直接，可是追到最早的来源，它更像是从“出租车”的概念里逐渐长成一个固定词。你可以把 taxi 想成来自法语里的那种日常用法，后来在英语国家被直接借用，并且意思越来越固定：就只指那种付钱坐的车和这项服务。因为它的历史比较短，所以你不太会像很多长词那样，拆出一堆清晰的词根词缀。它更像是语言里的“借来就用”，然后用得越多，就越稳定。顺便提一句长得像的同族词：taxiway 和 taxiing 也都和 taxi 这个动词概念有关，但用法不同。taxiing 常见于飞机场，意思不是“坐出租车”，而是飞机在地面慢慢滑行；taxiway 是给飞机滑行的那条道。你看，同一个字形，不同语境就会带来不同含义，这也很有意思。 11 00:03:02,280 --> 00:03:07,879 Dean：So what did this word originally mean, and how did the meaning change over time? 12 00:03:08,379 --> 00:04:19,420 茉莉：故事可以从法国说起：在很早的时候，人们用一个和 taxi 相关的词来表达“打车、乘车那类动作和服务”。当这个概念进入英语之后，英语人把它当作一个现成的词来用，意思自然就更具体了：在城市里，你付钱就能坐的一种交通工具，也就是出租车。随着生活场景越来越多，taxi 就不只是“某一次坐车”，它慢慢变成“一个固定的选择”，比如你打电话叫 taxi。然后又因为航空领域也需要一个词来描述“飞机在地面滑行”，英语就借用了同样的形式：taxiing 和 taxiway 出现时，含义完全从“城市里的出租车”转到“飞机在地面移动”，但它们共享的是“move slowly on the ground”这种动作感。到了今天，taxi 在日常英语里几乎总是和 city travel、calling a driver 这些场景绑在一起；而在机场语境里，它又变成了技术词。对我来说最有趣的是：同一个词看起来像是直接借过来的，但它在不同领域居然还能“长出”新意思。下一部分我们就讲搭配、场景与互动。 13 00:04:19,920 --> 00:04:32,879 Dean：Imagine you are standing outside a restaurant after work. It is late, and it is raining. You need to get home fast. What collocation can we use with taxi in this situation? 14 00:04:33,379 --> 00:04:51,459 茉莉：第一个搭配是 call a taxi。语感是“打电话/发起叫车请求”，强调你在联系出租车服务。这个用法很自然，尤其是在出门、赶时间、找不到车的时候。你不需要说得很复杂，比如 just call a taxi 就够了。 15 00:04:51,959 --> 00:04:55,799 Dean：In the rain, I called a taxi and went home. 16 00:04:56,299 --> 00:05:05,419 茉莉：这句话里 call 的动作很关键：先联系，再出发。这个搭配在日常聊天和新闻里都很常见。 17 00:05:05,919 --> 00:05:20,319 Dean：Now think about a school day. You have class at 9:00, and your friend lives far away. You do not want to walk, so you plan the trip. How do we use taxi in this kind of plan? 18 00:05:20,819 --> 00:05:39,059 茉莉：第二个搭配是 take a taxi。它更像“乘坐出租车来完成行程”，强调你坐上车去目的地。注意 take 用在“交通方式”上很常见，比如 take the bus 或 take a taxi，这样英语听起来更地道。 19 00:05:39,559 --> 00:05:43,719 Dean：I take a taxi to school when I am late. 20 00:05:44,219 --> 00:05:55,739 茉莉：这里 take a taxi 就是在表达“用出租车当交通方式”。如果你说得更具体一点，比如 take a taxi to the station，也会更清楚。 21 00:05:56,239 --> 00:06:10,639 Dean：Let’s switch to a shopping or hotel situation. You arrive somewhere and you see a place where taxis wait. You want to go somewhere quickly, so you go there. What taxi collocation do we use for that? 22 00:06:11,139 --> 00:06:28,739 茉莉：第三个搭配是 taxi stand。它指的是“出租车停靠点/候车区域”，通常就在街边、景点附近，或者酒店附近。你去那里不是为了打电话，而是直接在等车，所以这是和叫车相关但又不同的场景。 23 00:06:29,239 --> 00:06:33,399 Dean：We waited at the taxi stand for ten minutes. 24 00:06:33,899 --> 00:06:40,779 茉莉：这很自然，特别是旅行时。你也可以说 at the taxi stand 来说明地点。 25 00:06:41,279 --> 00:06:56,959 Dean：One more small situation: you arrive at the airport and you want to go downtown. Do you say “I take taxi to downtown” or “I take a taxi to downtown”? Choose the more natural one, and tell us why. 26 00:06:57,459 --> 00:07:27,699 茉莉：互动问题是：在句子里你该选哪个更自然——是 “I take taxi to downtown” 还是 “I take a taxi to downtown”。要点是：taxi 前面通常要加 a，表示“一辆出租车/乘坐出租车作为交通方式”。选对结构后，你再说明这是因为英语里交通方式用法常见 “take a taxi”。下一步我们想了解：taxi 和它的近义词之间有什么区别。 27 00:07:28,199 --> 00:07:33,959 Dean：What are some common synonyms of taxi? How are they different in usage? 28 00:07:34,459 --> 00:07:44,219 茉莉：常见近义词有：cab、hired car、ride、chauffeur。我们一个一个来对比，先看第一个。 29 00:07:44,719 --> 00:07:49,839 Dean：OK, what is the first synonym? How should I use it correctly? 30 00:07:50,339 --> 00:08:13,539 茉莉：cab。cab 也表示“出租车”，但语气更口语，常见于英国英语或更日常的美国英语。一般来说，它更强调“那一辆车/那种服务”，而不是强调“市内交通方式”这个抽象概念。常见搭配是 take a cab 或 get a cab。例句：I took a cab to the hotel. 31 00:08:14,039 --> 00:08:18,359 Dean：Nice. What about the next synonym? How is it different? 32 00:08:18,859 --> 00:08:45,259 茉莉：hired car。hired car 指“租来的车”，重点在“付费租用一辆车”，不一定是带司机的出租车服务，也可能是租车公司提供的用车。它的使用场景更偏向旅行或正式安排，语气比 taxi 更具体、更“合同/安排感”。常见搭配是 hire a car 或 rent a car。例句：We hired a car for three days. 33 00:08:45,759 --> 00:08:48,639 Dean：What about the third synonym? 34 00:08:49,139 --> 00:09:17,939 茉莉：ride。ride 是“搭便车/顺路带你一程/付费坐车的一段行程”的意思，更像强调这一次“出行机会”，不一定指出租车这种固定交通工具。它通常更口语，也更灵活，可以和很多交通方式搭配，但当你说 taxi 的时候，ride 不会自动让人想到出租车。常见表达是 get a ride 或 ask for a ride。例句：Can you give me a ride to the station? 35 00:09:18,439 --> 00:09:21,799 Dean：And the last one? 36 00:09:22,299 --> 00:09:46,779 茉莉：chauffeur。chauffeur 指“有司机的专车服务”，通常更正式、更高档，重点在专业司机和服务质量。它不适合随口说一辆出租车，因为它的语气更像预约、商务或礼宾用车。常见搭配是 hire a chauffeur 或 have a chauffeur. 例句：They hired a chauffeur for the evening. 37 00:09:47,279 --> 00:09:51,439 Dean：Can you summarize when to use which word? 38 00:09:51,939 --> 00:10:21,699 茉莉：总结一下：想说最普通的“出租车”，用 taxi 最稳；想要更口语、更日常的“出租车”，用 cab；如果你强调“付费租用一辆车”的安排感，不一定是传统出租车，就用 hired car；如果你只想说“要一段让你到目的地的搭乘/行程”，用 ride 更自然；如果你强调“带专业司机的高档用车服务”，用 chauffeur。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:10:22,199 --> 00:10:28,599 Dean：We learned a lot today. Now let’s relax with a fun short story about a taxi. 40 00:10:29,099 --> 00:10:30,539 茉莉：什么故事？ 41 00:10:31,039 --> 00:10:52,639 Dean：So, it’s Monday morning. I am at the office, and I feel sleepy. My friend Sam says, “We need coffee. Right now!” But the coffee place is far. So Sam says, “Let’s call a taxi.” I say, “Okay, okay. I will call a taxi.” 42 00:10:53,139 --> 00:10:58,100 茉莉：听起来很真实！然后呢？他们真的很快就走了吗？ 43 00:10:58,600 --> 00:11:23,399 Dean：Yes, but then something funny happened. A minute later, our meeting room door opens. It’s our boss. She asks, “Why are you all going out?” Sam says, “We called a taxi for coffee.” The boss smiles and says, “Good. But first, take a taxi to the training room. We have a presentation!” 44 00:11:23,899 --> 00:11:32,220 茉莉：哈哈！所以“take a taxi”变成了办公室里的安排游戏吗？ 45 00:11:32,720 --> 00:11:56,080 Dean：Exactly. We were confused. Then we understood the joke. The boss didn’t mean a real taxi for the street. She meant, “Go fast like a taxi.” Still, Sam goes, “Okay!” and acts like a taxi driver. He even announces, “Taxi! Taxi!” After five minutes, everyone starts laughing, and we finally get our real coffee. 46 00:11:56,580 --> 00:12:12,580 茉莉：太好笑了！这个故事里最关键的用法是：先用 call a taxi 表示叫车请求；再用 take a taxi 表示乘坐出租车出行。虽然最后是误会，但这两个搭配都用得很自然。 47 00:12:13,080 --> 00:12:26,520 Dean：Today we learned taxi as a common noun for city travel. We practiced calling a taxi, taking a taxi, and waiting at the taxi stand. See you next time. Bye, and have a great day!

1 00:00:00,000 --> 00:00:17,760 Dean：Today we learn the word “slide.” It means “to move smoothly and quickly on a surface” or “to move with a sliding motion.” It is like “move quickly without lifting your feet.” Moli, how do you understand “slide” in Chinese? 2 00:00:18,260 --> 00:00:42,740 茉莉：“Slide” 是指“滑动、滑行”。也可以说“顺着表面滑过去”，比如孩子玩滑梯或物体在地上滑动。英文里可以对应成 “move smoothly on a surface.” 它通常是动词，也常用于名词，比如 “a slide” 指滑梯。你把它当作动词用，还是名词用比较多？ 3 00:00:43,240 --> 00:01:02,760 Dean：“Slide” is usually a verb. You slide when you move smoothly on a surface. We also use “slide” for a quick move, like in a game or a video. Now let’s use example sentences to learn it. Sentence 1: “The child slid down the slide and smiled.” 4 00:01:03,260 --> 00:01:24,540 茉莉：这句话在讲场景：一个孩子从“滑梯”上滑下来，然后笑了。这里的 “slid” 就是 “slide”的过去式，表示动作发生在过去。需要注意的是 “slide” 在这里是和游乐场滑梯有关的常见用法。Dean, can you explain this sentence in simpler English? 5 00:01:25,040 --> 00:01:38,640 Dean：This sentence is about a past action. The child moved down smoothly, like on a playground slide. Sentence 2: “Be careful, the floor is wet, and you may slide.” 6 00:01:39,140 --> 00:01:58,019 茉莉：这句话在讲：地面很湿，所以要小心，可能会滑倒。这里的 “slide” 不一定是玩滑梯，更像是脚下打滑、从原本位置滑过去的意思。Dean, please continue and explain the feeling of this sentence in your simple English, and then give example 3. 7 00:01:58,519 --> 00:02:08,599 Dean：We use “slide” here for a small accident risk. It can happen when the ground is slippery. Sentence 3: “I slid the card across the table.” 8 00:02:09,099 --> 00:02:26,379 茉莉：这句话是在说你把卡片在桌面上“推过去/滑过去”，动作很轻、很顺。这里的 “slide” 是“让东西在表面移动”的意思，不是人在地上滑行。接下来我们将讲词根词缀与词源。 9 00:02:26,879 --> 00:02:39,359 Dean：Now, Moli, let’s talk about the word parts and where “slide” comes from. In A2 level terms, what are the root, any affixes, and the etymology of this word? 10 00:02:39,859 --> 00:03:42,899 茉莉：好，我们就把 slide 想成一个“由来有故事的词”。它现在看起来很简单，但实际上它和“沿着某个面滑动”的动作很紧密。先说词根词缀：slide 本身就是核心部分，基本没有复杂的前缀或后缀在里面，所以你可以把它理解成“动词的词干”，意思就是“滑、滑动”。当它想表达不同时间或不同语法身份时，就靠变化形式，比如过去式 slid，或者现在分词 sliding。至于同族词，英语里还会用到来自同一行动感觉的词，比如 slide 的名词形式会变成 a slide，意思就是“滑梯”；还有一些更偏“动作过程”的说法，比如 sliding 这种带进行感的形式，也能让你体会它是“正在滑”的画面感。你会发现这些亲戚词都围绕同一个核心动作：平滑地移动，不是突然跳过去。 11 00:03:43,399 --> 00:03:51,719 Dean：So what did this word originally mean, and how did the meaning change over time? Tell it like a small story, please. 12 00:03:52,219 --> 00:04:53,019 茉莉：好像有点像这样：很久以前，英语借用了来自更早的日耳曼语家族的词形，那时候强调的也是“滑动、沿着表面移动”的动作画面。后来词形逐渐变得更短、更好记，就越来越像我们今天看到的 slide。与此同时，它的使用范围也更自然了：最开始你可以把它理解成一种真实的动作，比如在冰面或泥地上那种滑动感；再后来，人们把它用到各种“带滑动路线的场景”，比如滑梯、抽屉、甚至比赛里的滑行动作。你会发现它从“动作本身”慢慢扩展成“动作带来的移动方式”，所以除了地上真的滑，也可以用来讲“迅速地移动”这种感觉。最有趣的是：一个词就能把从地面到游戏再到日常表达的画面都串起来，而且词形变化不多，却特别好用。下一部分我们再讲它最常搭配的词和你在真实对话里怎么用它。 13 00:04:53,519 --> 00:05:10,799 Dean：Imagine you are at the bus stop in the morning. It just rained, and the pavement is shiny. You try to walk fast, but your foot loses control. In that moment, what would we say with “slide”? 14 00:05:11,299 --> 00:05:29,379 茉莉：第一个搭配我们用 “slip and slide”。它的感觉很生活化，画面感强，强调“鞋子打滑，然后身体跟着在表面滑一下”的情况。常见于日常描述，尤其是孩子玩水、雨后地面、或者你差点滑倒这种场景里。 15 00:05:29,879 --> 00:05:35,319 Dean：You can say: “I slipped and slid, but I caught myself.” 16 00:05:35,819 --> 00:05:47,659 茉莉：这句话里 “caught myself” 就是“及时稳住自己”。整体很自然，因为 “slipped and slid” 把滑倒和滑动的过程说得很清楚。 17 00:05:48,159 --> 00:06:03,679 Dean：Now think about school. You are cleaning your classroom floor after lunch. Someone spilled juice, and you see a wet line on the floor. You want to warn your classmates. In this kind of situation, how can we use “slide”? 18 00:06:04,179 --> 00:06:24,019 茉莉：第二个搭配是 “slide on (something)”。它强调“在某个表面上滑过去”，比如在湿地、冰面、地板上。这个搭配在提醒别人小心时很常用，比说“你会摔倒”更具体，因为它直接说明“滑”的位置在什么表面上。 19 00:06:24,519 --> 00:06:29,959 Dean：For example: “Don’t run. You may slide on the wet floor.” 20 00:06:30,459 --> 00:06:40,539 茉莉：这里的 “wet floor” 是关键场景信息；整句话用 “may” 会更符合提醒语气，不会太吓人，但足够让人重视。 21 00:06:41,039 --> 00:06:55,919 Dean：Let’s move to a sports moment. You are watching a basketball game. A player makes a fast move on the court and moves in a smooth way to change position. What expression with “slide” fits this scene? 22 00:06:56,419 --> 00:07:15,619 茉莉：第三个搭配是 “slide into (a position/role)”。它的语感是“滑着过去，慢慢进入某个位置”，常用于体育、比赛里的移动，也可以用于更通用的社交场景，比如“顺势加入某个对话”。它比 “go into” 更有动作画面。 23 00:07:16,119 --> 00:07:21,079 Dean：You could say: “He slid into a new position and passed the ball.” 24 00:07:21,579 --> 00:07:32,779 茉莉：这句里 “a new position” 指场上站位的变化；用 “slid into” 就是强调那种顺滑、迅速但不慌乱的移动感。 25 00:07:33,279 --> 00:07:52,159 Dean：Quick practice time. Imagine you are making a car video. You want to describe a car moving on a road with snow. Should you say “The car slid on the snow,” or “The car slide on the snow”? Which one is correct? Give it with a full sentence. 26 00:07:52,659 --> 00:08:15,379 茉莉：题目是让你在句子里选正确的形式。要点是：动词 “slide” 需要和时态对上。这里描述发生的情况，最自然的是用过去式，所以 “slid”。你可以回答类似 “The car slid on the snow.” 接下来我们也会继续了解：这个词和近义词到底有什么不同，怎么选更地道。 27 00:08:15,879 --> 00:08:22,119 Dean：What are some common synonyms of “slide”? How are they different in usage? 28 00:08:22,619 --> 00:08:34,779 茉莉：常见近义词可以有 4 个：glide、slip、slide（不变）、scoot、slide into。我们一个一个来对比，先看第一个：glide。 29 00:08:35,279 --> 00:08:40,559 Dean：OK, what is the first synonym? How should I use it correctly? 30 00:08:41,059 --> 00:09:08,739 茉莉：glide。含义差别是 “glide” 更强调“平稳、轻轻地滑行”，通常没有 “突然失去控制” 的感觉。适用场景更像风、船、雪橇那种安静的移动，或动作很优雅的画面。语气更中性、偏描述，不像提醒危险那样直接。例句：The swan glided across the lake. 还可以说：She glided into the room quietly. 31 00:09:09,239 --> 00:09:13,239 Dean：Got it. What about the next synonym? How is it different? 32 00:09:13,739 --> 00:09:39,659 茉莉：slip。含义差别是 “slip” 更常表示“短暂的不小心打滑”，结果可能是你摔倒或快要摔倒，所以有 “意外” 的感觉。适用场景常用于湿地、油面、冰面这类风险提醒。语气往往是轻微的意外，而不是平稳的移动。例句：I slipped on the wet floor. I didn’t fall, but I slipped for a second. 33 00:09:40,159 --> 00:09:43,359 Dean：Thanks. What is the third synonym? 34 00:09:43,859 --> 00:10:11,379 茉莉：scoot。含义差别是 “scoot” 更偏“快速挪动”，通常距离不大，而且不一定是沿着滑动表面，也不强调像 slide 那样的顺滑路线。适用场景常用于口语，比如让座、快速往前挪，或催你快点过来。语气更随意、很生活化。例句：Scoot over and make some space. Hurry, scoot to the front. 35 00:10:11,879 --> 00:10:15,559 Dean：Great. Is there a fourth one? How is it different? 36 00:10:16,059 --> 00:10:51,579 茉莉：scoot 之后我们就要用你之前很熟的短语型表达：slide into。它不只是单词近义，而是用法上更具体。含义差别是它强调“顺着动作进入某个位置或角色”，像体育移动或社交里自然加入。适用场景通常是“进入某个位置”这种目标很清楚的时候。语气比简单的 go in 更有画面感，也更自然地表示“滑进去”。例句：He slid into the chair and smiled. She slid into the conversation smoothly. 37 00:10:52,079 --> 00:10:57,679 Dean：Can you summarize when to use which word? 38 00:10:58,179 --> 00:11:27,299 茉莉：总结一下：想表达平稳、轻柔、像滑过去但不危险，就用 glide；想表达不小心打滑、可能要摔倒，就用 slip；想表达快速挪一点、距离不大，用 scoot；如果你要说“顺势进入某个位置或状态”，就用 slide into。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 39 00:11:27,799 --> 00:11:36,279 Dean：We have learned so much. Now let’s relax with a fun short story about “slide.” 40 00:11:36,779 --> 00:11:38,859 茉莉：什么故事？快说！ 41 00:11:39,359 --> 00:12:04,479 Dean：Today, I was at the school office. It was Monday morning. I carried a big box of papers. Then I saw a wet spot on the floor. A sign said, “Careful! The cleaning spray is fresh.” I tried to walk around it, but my shoe touched the edge. Oh no—I slipped a little. Then I slid on the wet spot and bumped the box. 42 00:12:04,979 --> 00:12:09,619 茉莉：哎呀，听起来很尴尬！那你怎么收拾现场？ 43 00:12:10,119 --> 00:12:32,039 Dean：My coworker, Sam, rushed over. He said, “Don’t worry. Just slide into the chair and breathe.” So I did. I moved fast, like I was “slide into the chair.” But the chair rolled too, and my box slid with it. Now papers were flying everywhere. Sam laughed and said, “Look! The papers are doing a perfect slide show!” 44 00:12:32,539 --> 00:12:51,739 茉莉：哈哈，这个笑点太真实了！总结一下：你用 “slide on (something)” 来说在湿地那一小段滑过去；又用 “slide into (a position)” 来说顺势滑进椅子里。最后还配合 “slide show” 这个梗，太有画面感了。 45 00:12:52,239 --> 00:13:07,279 Dean：That’s the end of our word journey today. Remember: slide can mean moving smoothly on a surface, and it can also be used for smooth movement into a position. Thanks for listening, and keep practicing. See you next time—stay cheerful!

1 00:00:00,000 --> 00:00:14,080 Dean：Today we will learn the word shampoo. Shampoo means a liquid you put on your hair to wash it. In simple words, shampoo is hair-washing soap. Moli, how do you understand this word in Chinese? 2 00:00:14,580 --> 00:00:29,780 茉莉：“shampoo”指的是洗头用的清洁液或泡沫，用来把头发洗干净。英文对应是 hair-washing liquid。它通常是名词，最常见用法是：wash your hair with shampoo。 3 00:00:30,280 --> 00:00:43,560 Dean：Shampoo is usually a noun. People use it for washing hair in the shower or at home. Let’s use examples to learn it. Example 1: I buy shampoo for my hair every month. 4 00:00:44,060 --> 00:00:55,900 茉莉：这句话的意思是：他每个月都会买洗发水，用来洗自己的头发。这里的 shampoo 指的是“洗头用的清洁液”。Dean, please explain the sentence in simpler English. 5 00:00:56,400 --> 00:01:09,840 Dean：The sentence feels like a normal habit. “Every month” shows it happens again and again. Example 2: My kid says the shampoo smells like fruit, so he wants to use it. 6 00:01:10,340 --> 00:01:22,820 茉莉：这句话的场景是：一个小孩闻到洗发水味道很好，所以他想用。这里的 smells like 是“像……一样闻起来”的意思。Dean, please continue in simpler English. 7 00:01:23,320 --> 00:01:33,400 Dean：It shows a child’s opinion about the smell. He likes it, so he asks to use it. Example 3: Don’t get shampoo in your eyes. 8 00:01:33,900 --> 00:01:47,500 茉莉：这句话是在提醒人要小心：不要让洗发水进入眼睛，因为会很不舒服。这里的 get in 表示“进入某个地方”。Next, we will talk about roots and origins of the word. 9 00:01:48,000 --> 00:01:58,560 Dean：Moli, what are the word roots, affixes, and the etymology of shampoo? Can you explain how the parts of the word relate to its original meaning? 10 00:01:59,060 --> 00:03:53,300 茉莉：好，我们把 shampoo 当成一个“看起来像一块拼图”的词来聊。它现在的拼写和读音我们都熟了，但它的来源其实和一个动作有关。你可以把它想成：一开始它不是“洗发水这个东西”的名字，而更像是在说“揉一揉、按摩一下”。英文里这个感觉很重要，因为后面“用来洗头”的意思就是从“把头皮和头发处理干净”这件事慢慢走出来的。至于词的构成，它不像 some 这种一眼就能看出前后缀的那种结构，更像是从别的语言借来的整体词，慢慢被英语采用并固定成今天的形式。 同时，shampoo 这一家也有一些“长得像但意思有差别”的亲戚词。比如有些词看起来也和“清洁、洗、揉搓”这类动作有关，但它们不一定专门指洗头这种场景。有的会更偏向一般的清洗行为，有的会偏向按摩或轻微的“搓洗”动作，所以你会看到：同族的影子会让人觉得“它们都跟清洁和处理有关”，但真正最常见、最贴近日常用法的还是 shampoo 这个名词，指的就是洗头时用的那种产品。 再讲它的身世就更像故事了：很早以前，人们用的“shampoo”更接近于一种手法和动作，而不是我们今天瓶子上的品牌味道。后来，这种动作和具体的清洗方式被越来越多的人固定下来，特别是在英国英语中，shampoo 开始常用于描述把头发洗净时的过程。再到更现代的时代，当产品、配方和使用步骤越来越标准化，“用来做这个动作的东西”就逐渐变成了主角，于是意思就从动作慢慢走向了“洗头用的清洁液”。我觉得最有趣的是：同一个词，竟然能从“做一件事的手法”慢慢变成“你拿来用的东西”。 11 00:03:53,800 --> 00:04:08,840 Dean：So how did that original meaning of “a washing action” connect to the idea of a bottle you buy today? And when did people start using shampoo mainly as a product word instead of just a verb-like action? 12 00:04:09,340 --> 00:04:22,939 Dean：Imagine you forgot your shower stuff at home. You are in a small apartment, and the bathroom has only one bottle. What would you say to use the word shampoo here, like a product? 13 00:04:23,439 --> 00:04:49,839 茉莉：第一个搭配：use shampoo。这个用法很自然，意思是“使用洗发水来洗头”。重点是它是动词短语，用在日常行为里，而不是说“shampoo is…”。另外，英语里常见说法不是“wash your hair with shampoo”才算对，独立用 use shampoo 也很口语、很常用，适合你这种“我该用什么”的场景。 14 00:04:50,339 --> 00:04:56,579 Dean：Use shampoo in the shower. Example: I use shampoo every morning. 15 00:04:57,079 --> 00:05:10,839 茉莉：这句很自然。every morning 表达习惯时，用 use shampoo 就很好懂。注意 shampoo 当作物品来“用”，所以后面接的是 use，而不是把它当成动作动词。 16 00:05:11,339 --> 00:05:22,539 Dean：Now think about school. Your class has a health week, and you need to write a short poster about hair care. What words would you use for the product and the action? 17 00:05:23,039 --> 00:05:46,559 茉莉：第二个搭配：wash your hair with shampoo。这个是最经典、最地道的搭配之一，意思是“用洗发水洗头”。它比只说 use shampoo 更完整，因为它把动作 wash your hair 和工具 with shampoo 连在一起。并且 with shampoo 让听的人立刻知道你用的是什么。 18 00:05:47,059 --> 00:05:54,099 Dean：Wash your hair with shampoo. Example: I wash my hair with shampoo twice a week. 19 00:05:54,599 --> 00:06:06,599 茉莉：twice a week 稍微比 every day 更具体，这很适合做作业或海报那种表达。这个搭配的语感就是“用某个东西来完成清洁动作”。 20 00:06:07,099 --> 00:06:18,139 Dean：Let’s move to a social moment. You visit a friend, and they show you their new bathroom. They say, “Try this.” What would you say when you want a gentle product for your hair? 21 00:06:18,639 --> 00:06:39,439 茉莉：第三个搭配：gentle shampoo。这个通常用在“温和的洗发水”这种描述里，gentle 是形容洗护产品对头皮更不刺激、比较温柔的意思。这个搭配适合在聊天时介绍或询问，因为你不是在讲怎么做，而是在选哪种更舒服、更适合自己的产品。 22 00:06:39,939 --> 00:06:42,660 Dean：Try this gentle shampoo. 23 00:06:43,160 --> 00:06:52,439 茉莉：这句话用在朋友推荐产品时很自然。gentle shampoo 听起来就像产品的特点，而不是操作步骤。 24 00:06:52,939 --> 00:07:16,779 Dean：Last one. Imagine you read a label on a bottle. It says what to do, like instructions. Ask a question to check the right thing to do. For example, choose the more natural sentence: “How often should I use shampoo?” or “How often should I wash my hair with shampoo?” Which one is better? Give a hint: think about the label and the level of detail. 25 00:07:17,279 --> 00:07:46,559 茉莉：互动题是：你读到洗发水瓶子上的说明，想确认该怎么做。请你选择更自然的句子，并说明理由。答题要点：如果你只想问频率，用 How often should I use shampoo? 更简洁；如果你想更明确是“用洗发水来洗头”的完整做法，用 How often should I wash my hair with shampoo? 更具体。接下来我们想了解这个词和它的近义词有什么区别。 26 00:07:47,059 --> 00:07:52,499 Dean：What are some common synonyms of shampoo? How are they different in usage? 27 00:07:52,999 --> 00:08:05,319 茉莉：常见近义词我给你 4 个：cleanser，wash，hair wash，conditioner。我们一个一个来对比，先看第一个。 28 00:08:05,819 --> 00:08:11,099 Dean：OK, what is the first synonym? How should I use it correctly? 29 00:08:11,599 --> 00:08:32,879 茉莉：第一个是 cleanser。cleanser 意思是“清洁剂”，更像一个大类词，不一定只用在头发上，也可以用在面部或身体。它一般更正式一点，适合写产品说明或更严谨的场景。例句：This cleanser is good for sensitive skin. / I use a gentle cleanser to wash my face. 30 00:08:33,379 --> 00:08:38,019 Dean：Got it. What about the next synonym? How is it different? 31 00:08:38,519 --> 00:09:02,679 茉莉：第二个是 wash。wash 也可以表示“清洗用的液体或产品”，但它通常更偏口语和更通用，不像 shampoo 那样专指洗头产品。很多时候你会看到 wash 用在特定部位前面，比如 hair wash。例句：I use a hair wash for my scalp. / This body wash smells nice. 32 00:09:03,179 --> 00:09:06,379 Dean：Nice. Ask about the third synonym. 33 00:09:06,879 --> 00:09:29,599 茉莉：第三个是 hair wash。hair wash 更接近“洗头用的清洁产品”，但它比 shampoo 更不固定、更像是描述“用于头发清洗的东西”。在日常聊天里可以用，但写得更自然时很多人还是会选 shampoo。例句：I need to buy hair wash for next week. / This hair wash makes my hair feel clean. 34 00:09:30,099 --> 00:09:33,619 Dean：Thanks. What about the fourth synonym? 35 00:09:34,119 --> 00:09:58,599 茉莉：第四个是 conditioner。conditioner 的重点不是“清洗”，而是“护发/护发素”，用在 shampoo 之后，让头发更柔软、更容易梳。语气上它更像洗护步骤里的第二步，所以用错会让句子不自然。例句：I shampoo first, then I use conditioner. / My conditioner makes my hair soft. 36 00:09:59,099 --> 00:10:02,459 Dean：Can you summarize when to use which word? 37 00:10:02,959 --> 00:10:37,359 茉莉：总结一下：如果你指“洗头用的产品”，最稳的是 shampoo；如果你想说更一般的“清洁剂”，用 cleanser，但它不专指头发；如果你想表达“洗头用的东西”但更口语一点，用 hair wash；如果你只想讲“一种通用的洗涤产品”，wash 可以用，但通常需要更明确的对象；如果你在谈“护发素/护发产品”，用 conditioner，它通常是在 shampoo 之后用。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。 38 00:10:37,859 --> 00:10:45,859 Dean：We have learned so much. Now let’s relax with a fun short story related to shampoo. 39 00:10:46,359 --> 00:10:48,119 茉莉：什么故事？ 40 00:10:48,619 --> 00:11:01,099 Dean：Yesterday, I had a small problem at work. In my office, there is one shared bathroom. In the shower, there was only one bottle, and it said shampoo. 41 00:11:01,599 --> 00:11:06,399 茉莉：哎，这也太像“命运的洗发水”了吧。然后呢？ 42 00:11:06,899 --> 00:11:30,259 Dean：So I said, “Great. I will use shampoo.” After my shower, I wanted to look professional for the meeting. But my friend Sam knocked on the door and asked, “Can you help me?” I said, “Sure.” Then he showed me his hair. He was crying because he used shampoo… on his beard. 43 00:11:30,759 --> 00:11:36,999 茉莉：哈哈，原来他没看清楚场景。那这事怎么变成更搞笑的呢？ 44 00:11:37,499 --> 00:12:00,379 Dean：The next day, HR had a “Personal Care Tips” poster. It said, “Wash your hair with shampoo.” And under that, in small letters, it said, “Please do not use shampoo as face paint.” Sam saw the poster and laughed. He said, “Now I know. I should use gentle shampoo… for hair, not for my beard art!” 45 00:12:00,879 --> 00:12:22,639 茉莉：我明白了：这个故事里最关键的搭配是用来洗头的两种方式。一个是用 shampoo：use shampoo；另一个是更完整的动作搭配：wash your hair with shampoo。再加上描述产品时可以用 gentle shampoo，表示更温和的洗发水。 46 00:12:23,139 --> 00:12:46,659 Dean：Today we learned shampoo as a common word. We practiced using it for daily habits, like use shampoo, and for the full action, like wash your hair with shampoo. We also learned helpful product words, like gentle shampoo, and we checked how to ask about frequency on labels. Great job today, Moli. See you next time, and don’t get shampoo in your eyes!

1 00:00:00,000 --> 00:00:16,960 Dean：Hello, everyone. Today’s word is pollute. In English, pollute means to make air, water, or land dirty and not safe. A simpler way to say it is: to harm something by making it dirty. Moli, how do you understand this word in Chinese? 2 00:00:17,460 --> 00:00:36,019 茉莉：pollute 的意思是“污染”。它指的是把空气、水、土地等弄脏，导致环境变得不干净甚至不安全。英文里可以对应为“make the environment dirty” 。 这个词是什么词性，常怎么用？ 3 00:00:36,519 --> 00:00:50,279 Dean：Pollute is a verb. We often use it when we talk about the environment. People can pollute water, air, or land. Now let’s learn with an example sentence. Sentence 1: Many factories pollute the river. 4 00:00:50,779 --> 00:01:10,780 茉莉：这句话的意思是：很多工厂会把污染物排进河里，让河水变脏。场景是环境问题和工业排放。 如果你觉得 factories pollute 更难理解，先把 pollute 理解成“让河水变脏”。 Dean, can you explain the feeling of this sentence in simpler English? 5 00:01:11,280 --> 00:01:27,599 Dean：It sounds serious. We blame the factories for damaging the river. It is about a real problem, not just one small mistake. Sentence 2: The smoke can pollute the air. 6 00:01:28,099 --> 00:01:46,659 茉莉：这句话的意思是：烟会让空气变脏。场景是城市里有很多烟或火灾、燃烧带来的空气污染。 这里的 pollute 还是表示“让空气不干净”，所以 smoke 是造成污染的东西。 Dean, please continue and give us Sentence 3. 7 00:01:47,159 --> 00:01:53,719 Dean：Sentence 3: Don’t throw plastic here. It will pollute the beach. 8 00:01:54,219 --> 00:02:16,939 茉莉：这句话的意思是：不要把塑料扔在这里，因为它会把海滩弄脏、造成污染。场景是日常生活中的环保提醒。 这里的 It 指代塑料，表示它会带来长期的环境问题。 接下来讲词根词缀与词源。 9 00:02:17,439 --> 00:02:27,520 Dean：Moli, what are the word roots, affixes, and etymology of pollute? Please tell us in simple A2 to B1 English. 10 00:02:28,020 --> 00:03:59,379 茉莉：我们可以把 pollute 想成“从一个拉长的声音里长出来的词”。它来自拉丁语，原本和“清洗”“弄干净”那一类的意思有点相反：古时候的拉丁词大概是 polluere，意思偏向“使……不洁”“玷污”。所以它不是凭空出现的，而是一个表示“让某物变得不干净”的动作。 再看它的形状，pollute 在英语里看起来就像一个整体动词，没有特别明显的前缀或后缀可以拆给初学者。但你可以抓住它的“拉丁出身”：之后它进入法语和中世纪英语，逐渐就固定为“污染、弄脏环境”这种更具体的用法。 同族词方面，你可以顺路记一下污染相关的家族。比如 pollution 就是名词“污染”，它是在 pollute 的基础上加了表示结果或状态的形式；还有 polluted（被污染的）和 polluting（正在污染的）这种形容词用法，也都在说同一件事：有东西把环境或物品弄脏了。它们之间的区别主要是“动词在描述动作”，pollution 更像在说“状态或结果”，而 polluted 和 polluting 更像在描述“被影响的东西或正在发生的情况”。 至于词源演化，就像一条线慢慢拉长：最早强调“使人或物变得不洁”，后来用在水、空气、土地这些更具体的对象上，于是今天我们最常说的就是“让环境变脏、变得不安全”。 11 00:03:59,879 --> 00:04:10,439 Dean：So what did this word originally mean, and how did the meaning change over time? Tell it like a small story—where did it start, and where did it arrive? 12 00:04:10,939 --> 00:04:28,379 Dean：Imagine you are at home and you smell something bad from the kitchen. You learn that someone burned oil in a wrong way. The air feels thick, and your eyes hurt. In this situation, how do we use our word pollute? 13 00:04:28,879 --> 00:04:53,839 茉莉：第一个很常用的搭配是 pollute the air。意思是“污染空气”，强调空气变脏、变得不适合呼吸。这个搭配很贴近新闻里和日常里说“空气被污染”的表达，比如烟、燃烧、厨房油烟都可以用它来描述。英语里说到结果时，通常就是“污染了什么”，直接接 the air 最自然。 14 00:04:54,339 --> 00:05:02,979 Dean：In that situation, we say: pollute the air. Example: The smoke from that fire can pollute the air. 15 00:05:03,479 --> 00:05:16,439 茉莉：这句里 smoke 作“造成污染的东西”，can pollute 表示“可能会污染”。用在日常提醒或新闻口吻都很自然，听起来也很真实。 16 00:05:16,939 --> 00:05:33,419 Dean：Now think about school. Your class is going to write a science report about rivers. You visit a place near the river and see dirty water. The teacher asks you to describe what people did. What collocation with pollute should you use here? 17 00:05:33,919 --> 00:05:54,079 茉莉：第二个搭配是 pollute the water。意思是“污染水”，常用来讲河流、湖泊、饮用水等。这个搭配的语感比较正式，适合写作和课堂报告。你会经常在环境主题的文章里看到：先说污染源，再说污染了哪种水。 18 00:05:54,579 --> 00:06:03,379 Dean：For a river report, you can say: pollute the water. Example: People dump waste, and it pollutes the water. 19 00:06:03,879 --> 00:06:15,719 茉莉：dump waste 这个表达会让句子更像真实报道。pollute the water 也更容易让听众立刻明白问题是“水被弄脏了”，而不是别的意思。 20 00:06:16,219 --> 00:06:35,579 Dean：Third scene: you are walking in a park. You see a sign that says not to leave trash. After a windy day, you notice broken plastic on the grass. Someone tells you that trash can stay for a long time and harm nature. In this kind of scene, how do we use pollute? 21 00:06:36,079 --> 00:06:56,079 茉莉：第三个搭配是 pollute the land。意思是“污染土地”。它和 pollute the water、pollute the air 一样，也是固定结构，常用在环保科普里，强调垃圾会影响土壤与地面环境。这个搭配适合描述“地面被破坏、生态被影响”的情况。 22 00:06:56,579 --> 00:07:04,259 Dean：In this case, say: pollute the land. Example: Too much trash can pollute the land. 23 00:07:04,759 --> 00:07:13,560 茉莉：这里的 too much trash 让语气更口语，也更符合“公园里看到垃圾”的真实场景。pollute the land 的画面感很强。 24 00:07:14,060 --> 00:07:29,100 Dean：Quick question for you, listeners. Imagine a news report. Which is more natural: “Smoke pollutes the air” or “Smoke pollutes the water”? Choose one, and make one short sentence like it. 25 00:07:29,600 --> 00:07:50,560 茉莉：互动题要点：先想象新闻场景里“烟”主要影响的是空气，所以你要选更自然的搭配，并用 pollute 的结构造一句话。接下来我们想了解这个词和它的近义词有什么区别，比如在表达“让环境变脏”和“造成污染”时语气会不会一样。 26 00:07:51,060 --> 00:07:56,500 Dean：What are some common synonyms of this word? How are they different in usage? 27 00:07:57,000 --> 00:08:08,199 茉莉：pollute 的常见近义词可以有：contaminate，spoil，infect，harm。我们一个一个来对比，先看第一个；不要用括号 28 00:08:08,699 --> 00:08:13,979 Dean：OK, what is the first synonym? How should I use it correctly? 29 00:08:14,479 --> 00:08:51,759 茉莉：第一个近义词是 contaminate。 pollute 更像是“让环境变脏、变得不安全”，更常用于空气、水、土地这类广泛环境；contaminate 强调“被污染后可能带来危害”，常让人联想到细菌、化学物质或有毒成分。 更适合：讲食物、饮用水、实验材料、医疗相关或“有害污染物进入系统”的场景。 例句：The water can contaminate people if they drink it. If the lab tools are not clean, they can contaminate the sample. 30 00:08:52,259 --> 00:08:56,419 Dean：Got it. What about the next synonym? How is it different? 31 00:08:56,919 --> 00:09:29,079 茉莉：第二个近义词是 spoil。 spoil 的核心更偏向“把某物弄坏、变质”，既可以是食物味道变差，也可以是某种“干净状态”被破坏。它不像 pollute 那样一定要是环境污染，也不一定强调空气、土壤。 更适合：讲食物、气味、质量变差，或用“被破坏了原本的好状态”的意思。 例句：The milk will spoil in the heat. If you do not clean it, the smell can spoil the room. 32 00:09:29,579 --> 00:09:33,739 Dean：Thanks. Now, tell us about the third synonym. 33 00:09:34,239 --> 00:10:08,479 茉莉：第三个近义词是 infect。 infect 指“使人或动物得病”，强调病原体进入身体并造成感染。它和 pollute 不同：pollute 说的是环境或物被弄脏并带来不安全；infect 说的是“感染/生病”这一结果，通常要有具体的对象是人或动物。 更适合：医疗、疾病传播、接触后生病的场景。 例句：Dirty water can infect people with diseases. If you are sick, you can infect others. 34 00:10:08,979 --> 00:10:12,659 Dean：Okay. Can you explain the fourth synonym too? 35 00:10:13,159 --> 00:10:45,159 茉莉：第四个近义词是 harm。 harm 的意思更宽泛，是“伤害、损害”。它不一定强调“弄脏”，所以它可以用于环境，但更常用于“造成不良影响”，语气也比 pollute 更不具体。 更适合：讲结果，比如健康受损、生态受损，或写更一般的因果句。 例句：Pollution can harm our health. Too much smoke can harm people’s lungs. 36 00:10:45,659 --> 00:10:52,059 Dean：And if there are no more synonyms, can you summarize when to use which word? 37 00:10:52,559 --> 00:11:30,159 茉莉：总结一下： 如果你想说“让空气、水、土地变脏并不安全”，用 pollute；如果强调“有害物质进入并可能造成健康风险”，用 contaminate；如果强调“食物或状态变质变坏”，用 spoil；如果强调“让人或动物生病”，用 infect；如果只想表达“带来损害/不良影响”但不想太具体，用 harm。 最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事；不要用括号 38 00:11:30,659 --> 00:11:38,339 Dean：We have learned so much. Now let’s relax with a fun short story related to pollute. 39 00:11:38,839 --> 00:11:40,279 茉莉：什么故事？ 40 00:11:40,779 --> 00:12:09,099 Dean：Last week at school, I was in a group project. We had to make a poster about the environment. My friend Max said, “I can be the artist!” So he drew a river. Then he wrote, “People dump trash, and it pollutes the water.” Everyone nodded. It sounded perfect. Then Max smiled and said, “Now I will add smoke too.” He took a marker and made “smoke” above the river… but the marker was not new. It was leaking! 41 00:12:09,599 --> 00:12:16,799 茉莉：哎呀，马克笔漏墨了？那也太像真的污染了！他之后怎么处理？ 42 00:12:17,299 --> 00:12:49,299 Dean：He tried to clean it with a tissue. But the ink spread more. Our classroom windows were open, so the smell went everywhere. I said, “Max, stop! Don’t just wipe it fast. It can pollute the air.” Max said, “Okay, okay!” Then he used the wrong trash bin. The tissue went on the floor near the door. My teacher looked at the mess and said, “Now you also pollute the land.” Max whispered, “So the poster is finally real…” 43 00:12:49,799 --> 00:13:08,039 茉莉：哈哈！这个故事太有画面感了。总结一下：pollute 可以用在 pollute the water，pollute the air，pollute the land。关键是看你想说污染的是“水、空气还是土地”。而且故事里不是学名词，是用在真实场景里就懂了！ 44 00:13:08,539 --> 00:13:26,459 Dean：Great job today. We learned pollute as a verb, and we practiced common patterns for air, water, and land. Remember: keep things clean, or your “poster” might become a real mess. Thanks for listening, and see you next time. Stay cheerful!
