# 每日英语新闻 2026-10-03 本周天文好戏来了：10月4日（周日）土星将到达「冲日」位置——地球恰好运行到太阳和土星之间，土星在夜空中与太阳遥遥相对。这是一年中土星最亮、观测条件最好的时刻：太阳落山时它从东方升起，整夜可见，直到黎明才落下。冲日大约每年只有一次，所以这个周末是2026年用肉眼和小望远镜看土星的绝佳机会——甚至不需要昂贵设备，一台小望远镜就能清楚看到它著名的光环。NASA 本月观星指南和 EarthSky 天文网站均确认了这一日期。本期一起来学「opposition」「visible」「equipment」等高频实用词汇。 ## 英语知识点 1. **opposition** — （天文）冲日；（日常）反对 -例句：Saturn reaches opposition once every year. -翻译：土星每年到达一次冲日位置。 2. **visible** — 看得见的、可见的 -例句：The planet stays visible all night long. -翻译：这颗行星整夜都看得见。 3. **astronomer / sky watcher** — 天文学家 / 观星的人 -例句：Sky watchers call this the best night of the year. -翻译：观星的人把今晚称为一年中最好的夜晚。 4. **rise** — 升起；（数字等）上涨 -例句：The planet rises in the east around sunset. -翻译：这颗行星在日落时分从东方升起。 5. **equipment** — 设备、装备 -例句：You do not need expensive equipment to enjoy the night sky. -翻译：欣赏夜空不需要昂贵的设备。 6. **once each year** — 一年一次 -例句：This event happens only once each year. -翻译：这个天象一年只发生一次。 7. **look up** — 抬头看；（顺便）查阅 -例句：Step outside and look up at the stars tonight. -翻译：今晚到外面抬头看看星星吧。 ## 全文参考 Good morning, and welcome to Daily English News. Today is Saturday, October third. Here is a story that will make you look up at the night sky. This Sunday, October fourth, Saturn will reach opposition, one of the biggest events of the year for sky watchers. Opposition means Earth passes directly between the sun and Saturn, so the ringed planet sits opposite the sun in our sky. Why does this matter? Because this is when Saturn shines its brightest and stays visible all night long. The planet rises in the east around sunset and does not set until sunrise. The event happens only once each year, so this weekend is one of the best chances of twenty twenty-six to see Saturn. You do not need expensive equipment, either. Even a small telescope will clearly show its famous rings. So this weekend, step outside, look up, and enjoy the show.

标题 Walking Faster May Help Reverse Frailty, Study Finds 中文总结 觉得运动太晚了吗？一项发表在《PLOS ONE》的新临床试验给出了不一样的答案：走快一点，而不只是走得多，能帮助老年人对抗衰弱。研究者在14个退休社区让165位平均79岁的老人参加为期4个月、每周3次的步行计划：一半人随意慢走，另一半被要求在安全前提下尽量走快。结果快走组近70%的人在至少一项衰弱指标上有改善，慢走组只有46%；快走组在6分钟步行测试中也走得更远。衰弱影响多达一半的老年人，会提高跌倒和住院风险。结论很简单：加快脚步，快走可能是健康 aging 最好的药之一。 英语知识点 1. frailty (n.) 衰弱（老年医学常用词，指体弱、易受伤的状态） - *Frailty affects up to half of older adults.* - 衰弱影响着多达一半的老年人。 2. clinical trial (n.) 临床试验 - *A new clinical trial says walking faster can help older adults fight frailty.* - 一项新的临床试验表明，走快一点可以帮助老年人对抗衰弱。 3. pick up the pace (phr.) 加快速度、加快脚步 - *The message is simple: pick up the pace.* - 结论很简单：加快脚步。 4. as fast as they safely could (phr.) 在安全的前提下尽可能快 - *The other half were told to walk as fast as they safely could.* - 另一半人被要求在安全前提下尽可能快地走。 5. compared with (phr.) 与……相比 - *Nearly seventy percent of the fast walkers improved, compared with only forty-six percent of the casual group.* - 快走组近70%的人有改善，相比之下慢走组只有46%。 6. raise the risk of (phr.) 提高……的风险 - *Frailty raises the risk of falls and hospital stays.* - 衰弱会提高跌倒和住院的风险。 7. healthy aging (n.) 健康老龄化 - *A brisk daily walk may be one of the best medicines for healthy aging.* - 每天快走可能是健康老龄化最好的药之一。 全文参考 Here is a health story that proves it is never too late to start moving. A new clinical trial says walking faster, not just walking longer, can help older adults fight frailty. Scientists studied one hundred sixty-five older adults, with an average age of seventy-nine, in fourteen retirement communities. Everyone joined a four-month walking program, three times a week. Half walked at a relaxed, casual pace. The other half were told to walk as fast as they safely could. The results were clear. Nearly seventy percent of the fast walkers improved in at least one measure of frailty, compared with only forty-six percent of the casual group. They also walked farther in a six-minute fitness test. Frailty affects up to half of older adults and raises the risk of falls and hospital stays. The message is simple: pick up the pace. A brisk daily walk may be one of the best medicines for healthy aging. 双源验证 - TIME（2026-09-30）: "Walking Faster May Help Reverse Frailty" — PLOS ONE 新试验，14 retirement homes，快走组近70%至少一项衰弱类别改善 vs 慢走组46%（Danilovich 语录） - PLOS ONE 论文/官方新闻稿（Mirage.News 转载）：整群随机对照试验，165名参与者（12-14个社区），NIH资助；配套二次分析（102人）显示快走组步频100步/分 vs 慢走组77步/分，6分钟步行测试改善率65% vs 39%

【中文总结】 无糖饮料到底能不能喝？英国利物浦大学的科学家完成了迄今规模最大、时间最长的相关随机对照试验。研究招募了493名超重或肥胖的成年人，所有人都参加减重项目，一半人每天喝水，另一半人每天喝无糖饮料。两年后，两组减重效果几乎一样：无糖饮料组平均减了4.8公斤，喝水组减了3.7公斤，差异小到没有统计意义。两组的血压、胆固醇和体成分都有改善。研究者表示，"甜味剂扰乱食欲、危害健康"的担忧在这项严格的长期试验中并未得到支持。想戒糖又舍不得快乐水？换无糖版本，效果可能和喝水一样好。这项研究发表在《英国营养学杂志》上。 【英语知识点】 1. **as well as**（和……一样好） - 例句：This new phone works as well as the old one. - 翻译：这部新手机和旧的一样好用。 2. **weight loss**（减重、减肥） - 例句：Regular exercise is the key to healthy weight loss. - 翻译：规律运动是健康减肥的关键。 3. **calorie**（卡路里） - 例句：Diet drinks contain almost no calories. - 翻译：无糖饮料几乎不含卡路里。 4. **too small to be meaningful**（太小而没有意义） - 例句：The gap between the two teams was too small to be meaningful. - 翻译：两队的差距小得不具意义。 5. **blood pressure**（血压） - 例句：Walking every day can lower your blood pressure. - 翻译：每天散步可以降低你的血压。 6. **cholesterol**（胆固醇） - 例句：Oatmeal may help reduce bad cholesterol. - 翻译：燕麦可能有助于降低坏胆固醇。 7. **swap A for B**（用B替换A） - 例句：Try to swap chips for fruit at lunch. - 翻译：午餐试着用水果代替薯片。 ## 全文参考 Here is some good news for anyone who loves diet soda. A major new study says diet drinks work just as well as water for losing weight. Researchers at the University of Liverpool in the U.K. ran the longest study of its kind. They followed four hundred ninety-three adults for two years. Everyone joined a weight-loss program. Half drank water every day. The other half drank diet drinks with no-calorie sweeteners. After two years, both groups lost about the same amount of weight. The diet drink group lost four point eight kilograms, and the water group lost three point seven. The difference was too small to be meaningful. Both groups also saw better blood pressure and cholesterol. The researchers say the fear that sweeteners harm your health is not supported by this trial. So if you are trying to cut sugar, swapping soda for a diet version may be just as good as water. 本音频为 AI 生成，新闻读两遍：第一遍正常语速，第二遍加深印象，适合跟读练听力。

练乐器的孩子更聪明？美国东北大学的新研究给这个老话题添了新证据。科学家研究了76名7到9岁的儿童，其中一半每周练琴至少30分钟。结果发现，学音乐的孩子在词汇、数学和工作记忆测试中表现更好。脑部扫描还显示，这些孩子大脑中连接"听"和"说"区域的神经纤维排列更有序——简单说，他们脑内听觉与语言之间的"高速公路"修得更结实。研究者提醒这是相关性研究，还不能证明因果关系，但令人惊讶的是，孩子们并不需要苦练多年就能看到这种关联。家里有琴童的家长，下次孩子练琴时，不妨想想：那些看似吵闹的练习，可能正在悄悄塑造一个更好的大脑。本期新闻读两遍，第一遍正常语速，第二遍加深印象，适合跟读练听力。 英语知识点 1. practice an instrument（练习乐器） 例句：She practices an instrument for thirty minutes every day. 翻译：她每天练乐器三十分钟。 2. working memory（工作记忆） 例句：Working memory helps you hold information while you use it. 翻译：工作记忆帮助你在使用信息的同时记住它。 3. score higher on tests（在考试中得更高分） 例句：Students who read daily often score higher on tests. 翻译：每天阅读的学生考试往往得更高的分数。 4. in simple terms（简单来说） 例句：In simple terms, exercise makes your heart stronger. 翻译：简单来说，运动让你的心脏更强壮。 5. the link is striking（这种关联非常显著） 例句：The link between sleep and grades is striking. 翻译：睡眠和成绩之间的关联非常显著。 6. prove（证明） 例句：One study cannot prove that music makes you smarter. 翻译：一项研究无法证明音乐能让你更聪明。 7. build a better brain（塑造更好的大脑） 例句：Reading every night may help build a better brain. 翻译：每晚阅读可能有助于塑造更好的大脑。 ## 全文参考 Here's a story for every parent: new research says learning music may help children's brains grow stronger. Scientists at Northeastern University in Boston studied seventy-six children aged seven to nine. Half of them practiced an instrument, like the piano or violin, for at least thirty minutes a week. The other half did not. The young musicians scored higher on tests of vocabulary, math, and working memory. Brain scans also showed a difference. In children who played music, the fibers connecting sound and speech areas of the brain looked better organized. In simple terms, their brains built stronger roads between hearing and speaking. The researchers say they cannot yet prove music lessons caused the gains, but the link is striking. And the children did not need years of practice to show benefits. So the next time your child practices the piano, remember: those noisy sessions might be building a better brain.

NASA的小行星样本研究有了新结论。瑞士团队分析了OSIRIS-REx探测器2023年带回的贝努（Bennu）小行星样本（约120克），发现这颗小行星并非如以往认为的形成于寒冷的外太阳系，而是诞生在"雪线"附近——水蒸气凝结成冰的特殊边界地带。在那里，内太阳系的炽热物质与外部的冰冷物质混合，冰像胶水一样把微细尘埃粘成岩石，木星则挡住粗颗粒、只放行细尘。这项9月23日发表于《Science Advances》的研究认为，贝努可能是地球等行星原始"建筑材料"的最佳标本。（双源：Space.com + ETH Zurich/phys.org） 本期新闻读两遍，第一遍正常语速，第二遍加深印象，适合跟读练听力。 ## 英语知识点 1. **asteroid** (n.) 小行星 -例句：An asteroid named Bennu orbits the sun every 1.2 years.（一颗名叫贝努的小行星每1.2年绕太阳一圈。） 2. **sample** (n./v.) 样本；取样 -例句：The spacecraft brought samples of the asteroid back to Earth.（航天器把小行星样本带回了地球。） 3. **form** (v.) 形成 -例句：Scientists used to believe Bennu formed in the cold outer solar system.（科学家过去认为贝努形成于寒冷的外太阳系。） 4. **freeze into** (phr.) 冻结成 -例句：Water vapor freezes into ice near the snow line.（在雪线附近，水蒸气冻结成冰。） 5. **act like glue** (phr.) 像胶水一样起作用 -例句：Ice acted like glue, sticking dust particles together.（冰像胶水一样把尘埃颗粒粘在一起。） 6. **play a key role** (phr.) 起关键作用 -例句：Jupiter played a key role in Bennu's birth.（木星在贝努的诞生中起了关键作用。） 7. **the ingredients that built...** (phr.) 构建……的原料/要素 -例句：Bennu may show us the original ingredients that built Earth.（贝努可能向我们展示了构建地球的原始原料。） ## 全文参考 Good morning, and welcome to Daily English News. Today is Monday, September twenty-eighth. Here is a story about a space rock that may explain how Earth was born. NASA's OSIRIS-REx spacecraft visited an asteroid named Bennu, and in twenty twenty-three it brought pieces of it home, about one hundred twenty grams. A team in Switzerland has now finished studying those samples, and the results are surprising. Scientists used to believe Bennu formed far away in the cold outer solar system. Instead, the new analysis shows it was born near a special boundary called the snow line, where water vapor freezes into ice. There, material from the hot inner solar system and the icy outer regions mixed together, and ice acted like glue, sticking tiny dust particles into bigger rocks. Giant Jupiter played a key role too, blocking coarse material while fine dust flowed around it. Bennu may be our best look at the original ingredients that built Earth.

标题：This Saturday: The Harvest Moon Meets Saturn 【中文总结】 本周六（9月26日）是一年一度的"收获月"——离秋分最近的满月。在电灯发明之前，农民靠它明亮的光芒在日落后继续田间劳作，因此得名。收获月还有个特别之处：连续几个晚上，月亮几乎在同一时间升起。今年的收获月旁边还有"伴"：土星就在附近，肉眼即可看见；海王星也在不远处，但太暗淡，需要双筒望远镜才能找到。周末晚饭后，抬头看东方天空，就能欣赏这场天文秀。 【英语知识点】 1. **full moon** (n.) 满月 -例句：The full moon rises just after sunset. -翻译：满月在日落后不久升起。 2. **equinox** (n.) 昼夜平分点；春分/秋分 -例句：Day and night are almost equal on the autumn equinox. -翻译：秋分时昼夜几乎等长。 3. **keep doing something** (phr.) 持续做某事 -例句：Farmers kept working in their fields after dark. -翻译：天黑后农民们仍在田里继续劳作。 4. **in a row** (phr.) 连续地 -例句：The moon rises at nearly the same time for several nights in a row. -翻译：连续几个晚上，月亮几乎在同一时间升起。 5. **with the naked eye** (phr.) 用肉眼 -例句：Saturn is bright enough to see with the naked eye. -翻译：土星足够亮，用肉眼就能看到。 6. **faint** (adj.) 微弱的；暗淡的 -例句：Neptune is too faint to see without a telescope. -翻译：海王星太暗淡，没有望远镜看不到。 7. **step outside** (phr.) 走到户外 -例句：Step outside tonight and look at the sky. -翻译：今晚走到户外，看看天空吧。 ## 全文参考 Have you looked up at the night sky lately? This Saturday, September 26th, the Harvest Moon will light up the evening sky. The Harvest Moon is the full moon closest to the autumn equinox, which arrived earlier this week. Its name comes from an older time: before electric lights, farmers used its bright light to keep working in their fields after sunset. This full moon is special for another reason. Around this date, it rises at nearly the same time for several nights in a row. And it won't be alone up there. Saturn will appear nearby, bright enough to see with just your eyes. Neptune is close too, but it is too faint for the naked eye, so you will need binoculars or a telescope to spot it. So this weekend, step outside, look east just after sunset, and enjoy the show.

天文学家确认了人类迄今发现的最年轻的行星——Elias 2-24 b。它还不满一百万岁，是一颗仍在诞生过程中的"婴儿行星"，距离地球约450光年，质量与木星相当。这次发现让科学家惊讶，因为现有理论认为这么大的行星需要约五百万年才能形成。研究团队是在翻找夏威夷凯克天文台的旧档案数据时，在2018年和2020年的图像中发现同一个微小光点，从而确认了它的存在。科学家表示，研究这样的婴儿行星就像坐上时光机，能让我们看到数十亿年前太阳系是如何形成的。 ## 英语知识点 1. **astronomer** (n.) 天文学家 - Astronomers discovered a planet younger than anyone expected. - 天文学家发现了一颗比任何人预期都年轻的行星。 2. **massive** (adj.) 巨大的；质量极大的 - The new planet is about as massive as Jupiter. - 这颗新行星的质量和木星差不多大。 3. **dig through** (phr.) 翻找；从（大量资料）中搜寻 - Researchers found it by digging through old data. - 研究人员通过翻找旧数据发现了它。 4. **time machine** (n.) 时光机 - Baby planets are like time machines for scientists. - 对科学家来说，婴儿行星就像时光机。 5. **light-year** (n.) 光年 - The planet sits about 450 light-years from Earth. - 这颗行星距离地球约450光年。 6. **solar system** (n.) 太阳系 - Jupiter is the largest planet in our solar system. - 木星是太阳系中最大的行星。 7. **current** (adj.) 当前的；现在的 - Current theories say the planet should take longer to form. - 现有理论认为这颗行星的形成时间应该更长。 ## 全文参考 Astronomers have discovered the youngest planet ever found, and it is still being born. The planet, named Elias 2-24 b, is less than one million years old. That may sound old, but Earth is about four and a half billion years old, so this world is truly a baby. It sits about four hundred and fifty light-years from Earth, and it is about as massive as Jupiter, the largest planet in our solar system. The discovery surprised scientists, because current theories say a planet this size should take around five million years to form. Researchers found it by digging through old data from the Keck Observatory in Hawaii, spotting the same tiny dot of light in images from twenty eighteen and twenty twenty. Scientists say baby planets like this one are time machines, showing us how our own solar system formed billions of years ago.

睡眠不足第二天记不住东西？加拿大一项新研究给出了一个简单的补救办法。研究人员让 88 名年轻志愿者分别睡 8.5 小时或只有 4.5 小时，其中一半人在睡前以中等强度骑了 30 分钟动感单车。第二天早晨的记忆测试显示：睡眠被剥夺且没运动的一组记忆明显下降，而睡前运动过的一组几乎没受影响，成绩接近睡满整晚的人。研究者认为，运动增加了深睡眠（慢波睡眠），而深睡眠正是大脑把新信息存入长期记忆的关键时段。当然，运动不能代替睡眠——但如果偶尔不得不熬夜，晚间一次 30 分钟的快走或骑行，或许能帮你的记忆"止损"。 ## 英语知识点 1. **substitute (for)** — n. 代替品；替代物 - Exercise is not a substitute for sleep. - 运动不能代替睡眠。 2. **stationary bike** — n. phr. 动感单车；固定式健身自行车 - She rides a stationary bike for thirty minutes every evening. - 她每天晚上骑 30 分钟动感单车。 3. **moderate pace / moderate intensity** — 中等速度／中等强度 - Try to run at a moderate pace, not too fast. - 尽量以中等速度跑，不要太快。 4. **scored almost as well as** — 表现得分几乎和……一样好（as well as 同级比较） - This group scored almost as well as the group that slept a full night. - 这一组的得分几乎和睡满整晚的那组一样好。 5. **store new information** — 存储新信息（store 在此为动词） - Sleep helps the brain store new information. - 睡眠帮助大脑存储新信息。 6. **stay up late** — phr. 熬夜；晚睡 - I stayed up late finishing my report last night. - 我昨晚熬夜写完报告。 7. **a quick workout** — 一次快速（简短）的锻炼 - A quick evening workout may protect your memory. - 晚上一次简短的锻炼也许能保护你的记忆力。 ## 全文参考 Here is your English news for Tuesday, September twenty-second. Do you worry that a bad night's sleep destroys your memory? A new study from Canada offers some hope. Researchers asked eighty-eight healthy young adults to sleep either eight and a half hours or only four and a half hours. Before bed, half of them rode a stationary bike for thirty minutes at a moderate pace. The next morning, everyone took a memory test with faces and names. As expected, short sleep hurt memory. But the group that exercised scored almost as well as those who enjoyed a full night's rest. The researchers believe exercise increases deep sleep, which helps the brain store new information. Of course, exercise is not a substitute for sleep. Still, next time you must stay up late, a quick evening workout may protect your memory. （来源：SLEEP 期刊 2026 年研究 DOI 10.1093/sleep/zsag235；Medical Xpress、Medscape 双源交叉验证）

# 中文总结 「每天一万步」可能是最广为流传的健康目标，但一项发表在《英国运动医学杂志》上的大型新研究发现：走多少步固然重要，走多快同样关键。研究团队分析了近6.5万名英国成年人的数据，参与者佩戴运动追踪器一周，随后被随访约8年。结果显示：每天保持较快步速（约每分钟80步）步行至少30分钟的人，早逝风险明显降低；每天走不到5000步但走得快的人，获益与走5000-7500步但速度慢的人相当。而每天走7500-10000步的人，无论快慢，风险都是最低的。有趣的是，「一万步」这个数字其实源于上世纪60年代日本的一家计步器营销活动，并非科学结论。对没时间长时间走路的人来说，加快脚步、走得更带劲，同样是对心脏好的投资。 # 英语知识点 1. **briskly / brisk walk**（adv./n. 快步地；快走） -例句：Walking briskly for 30 minutes a day can improve your heart health. -翻译：每天快走30分钟能改善你的心脏健康。 2. **pick up the pace**（加快步伐） -例句：If you want to burn more calories, try to pick up the pace. -翻译：想燃烧更多卡路里，就试着加快步伐。 3. **be associated with**（与……相关联） -例句：Regular exercise is associated with a lower risk of many diseases. -翻译：规律运动与多种疾病的更低风险相关。 4. **takeaway**（n. 要点，核心结论） -例句：The main takeaway from the study is that every step counts. -翻译：这项研究的核心结论是：每一步都算数。 5. **striking**（adj. 惊人的，显著的） -例句：The researchers found a striking difference between the two groups. -翻译：研究人员发现两组之间存在惊人的差异。 6. **sedentary**（adj. 久坐不动的） -例句：Office workers often live a sedentary lifestyle. -翻译：上班族通常过着久坐不动的生活方式。 7. **follow-up / follow people for years**（随访，追踪调查） -例句：Scientists followed the participants for eight years to track their health. -翻译：科学家对这些参与者进行了8年的追踪以观察他们的健康状况。 # 全文参考 Here's a piece of health news that might change how you take your next walk. A major new study says you don't need ten thousand steps a day to live longer. You just need to walk a little faster. Researchers from Australia and Spain looked at data from nearly sixty-five thousand adults in the U-K. Each person wore a fitness tracker for one week. The scientists then followed them for about eight years. The results were striking. People who walked briskly for at least thirty minutes a day had a much lower risk of dying early. In fact, those who took fewer than five thousand steps, but walked at around eighty steps per minute, showed benefits similar to people taking seven thousand steps at a slower pace. Interestingly, the famous ten thousand step goal actually started as a marketing slogan in nineteen sixties Japan, not from science. So here's the takeaway: every step counts, but some steps count for more. Pick up the pace until you feel warmer and breathe a little harder, and your heart will thank you.

今天分享一条好玩的消息：多邻国（Duolingo）和 Supercell 旗下热门手游《荒野乱斗》（Brawl Stars）官宣联动。9月19日至9月30日，两只绿色吉祥物将在两款 App 里互窜门：多邻国的猫头鹰 Duo 会"占领"荒野乱斗的星际公园，玩家可以组队打 Boss 版巨型 Duo，答题才能不掉血；而荒野乱斗的仙人掌 Spike 会潜入多邻国的课程，学习者完成每日课程、保持连胜打卡，就能解锁限定奖励。两家公司说，这两位吉祥物争的其实是同一件事——用户的注意力时间。多邻国此前也做过类似联动，比如 2020 年的愤怒的小鸟和 2025 年的原神。对英语学习者来说，这也是个提醒：一点竞争感，往往是坚持每日学习的最好动力。 ## 英语知识点 1. **team up** — 组队、合作 - 例句：Let's team up and finish this project together. - 翻译：我们组队一起完成这个项目吧。 2. **face off** — 对决、正面交锋 - 例句：The two teams will face off in the final next week. - 翻译：这两支队伍下周将在决赛中正面交锋。 3. **take over** — 接管、占领 - 例句：A new coffee shop took over the old bookstore's location. - 翻译：一家新咖啡店接管了旧书店的位置。 4. **streak** — 连续打卡、连胜记录 - 例句：I've kept a 100-day streak on Duolingo. - 翻译：我在多邻国上保持了100天的连续打卡。 5. **unlock** — 解锁（奖励、功能） - 例句：Complete three lessons to unlock the special reward. - 翻译：完成三节课即可解锁特别奖励。 6. **mascot** — 吉祥物 - 例句：The team's mascot is a big green bird. - 翻译：这支队伍的吉祥物是一只绿色大鸟。 7. **crossover** — 联动、跨界合作 - 例句：The movie is a crossover between two famous franchises. - 翻译：这部电影是两个著名系列的联动作品。 ## 全文参考 Here's a fun story from the world of mobile apps. Duolingo, the famous language-learning app with the green owl mascot named Duo, is teaming up with Brawl Stars, one of the most popular mobile games in the world. Starting September nineteenth, the two mascots will face off across both apps for about two weeks. In Brawl Stars, Duo takes over a game area called Starr Park, where up to twenty players can team up to battle a giant version of the owl. In Duolingo, players can unlock the cactus character Spike by completing daily lessons and keeping their streaks alive. The two companies say the characters are fighting over one thing: people's time. Duolingo has run similar crossovers before, including Angry Birds in twenty twenty and Genshin Impact last year. For language learners, it is a playful reminder: a little competition can be a powerful way to keep studying every day.
