[] Unitree Unveils High-Speed Humanoid Robot and Achieves $50 Billion IPO Valuation (估值，资产定价). Chinese robotics maker Unitree has unveiled Superman, an experimental humanoid robot designed to study dynamic motion. In test footage, the headless robot demonstrated remarkable athletic (运动的，敏捷强壮的) capabilities, jumping over six feet off the ground and sprinting at more than twenty-eight miles per hour. Its elongated legs help stretch stride (大步，步幅) length to achieve higher running speeds. Two days later, Unitree completed its public listing on the Shanghai stock exchange with massive retail investor demand. The listing drove Unitree to an extraordinary market valuation of over fifty billion dollars, reflecting strong investor enthusiasm for embodied artificial intelligence.
宇树科技展示高速人形机器人并实现 500 亿美元上市估值。中国机器人制造公司宇树科技近日展示了一款名为 Superman 的实验性人形机器人，旨在研究高动态运动。在测试视频中，这款无头机器人展现了出色的运动能力，不仅原地起跳超过 6 英尺，冲刺时速更突破了 28 英里。其加长的腿部设计有助于拉长步幅，从而实现更快的奔跑速度。两天后，宇树科技在上海证券交易所完成挂牌上市，获得了散户投资者的超额认购。此次上市推动宇树科技达到了超过 500 亿美元的惊人市场估值，反映出投资者对具身智能的极高热情。（来源：Fast Company Co.Design）

[] Schools Implement Traffic Light Policies and Practical Tools to Guide Classroom AI Use. As generative artificial intelligence enters classrooms, schools are moving away from outright bans toward thoughtful (深思熟虑的，周到的) guidance. At Cheshire Academy, teachers receive training on prompt creation and model limitations while using AI tools to prepare lesson plans and grading rubrics (评分标准，评价量规). To help students use technology responsibly, the school introduced a simple traffic light system. A green label allows full AI assistance, red prohibits (禁止，阻止) any use, and yellow permits specific features like spell checking. Teachers also assign exercises where students review AI edits to ensure they maintain their personal voice.
学校推行“红绿灯”策略与实用工具以规范引导课堂 AI 使用。随着生成式人工智能进入课堂，学校正从一刀切的禁令转向更加深思熟虑的引导。在柴郡中学，教师们接受了提示词编写与模型局限性方面的培训，同时使用 AI 工具准备教案和评分量规。为了帮助学生负责任地使用这项技术，学校引入了简洁的“红绿灯”系统：绿灯代表完全允许 AI 辅助，红灯代表全面禁止，黄灯则允许拼写检查等特定功能。教师还布置了让学生审查 AI 修改意见的作业，以确保他们保留个人独特的表达风格。（来源：MIT Tech Review Society）
