Unit 4 Section Ⅱ “Understanding ideas”的新知学习环节-【新课程学案】2025-2026学年高中英语选择性必修第三册配套课件PPT（外研版）

该高中英语课件围绕“AI与未来”主题，系统覆盖词汇（分阅读、重点、拓展三级）、核心词汇（如assist、potential）、重点句式（如if not省略结构、have no choice but to do）及语用训练，通过课前默写导入，衔接词汇突破与句式解构，构建从基础积累到语篇应用的学习支架，帮助学生梳理知识脉络。 其亮点在于分层递进的词汇教学（会认、写对、活用）和“两层级”句式学习（结构变换与仿写），结合AI主题语篇综合训练（阅读、完形、微写作），培养语言能力（如高级词块运用）和思维品质（句式逻辑分析）。例如核心词汇assist通过归纳用法与多题型应用巩固，微写作要求运用本课词汇，助力学生语言输出。对学生可提升综合语用能力，对教师提供完整教学资源，提高教学效率。

Both conductors worked together on the final piece. EveR 6 is a robot built by the Korea Institute of Industrial Technology. It's about as tall as a person, and has a human-like face that can show emotions. It has joints in its neck, shoulders, elbows, and wrists.As a result, it can move its arms quickly and smoothly in many different directions. But EveR 6 doesn't think on its own like some advanced Artificial Intelligence programs.Instead, it has a limited group of movements that it has been trained to perform. To make these movements as natural as possible, EveR 6's movements are based on motions of real human conductors. When EveR 6 swung its baton (指挥棒) for the first time, a gong rang out. Every movement of the robot's arms brought more instruments into the mix, and the orchestra's music grew louder and more exciting. Mr Choi was impressed with the way EveR 6 moved. “The robot was able to present such detailed moves much better than I had imagined，” he said.But the robot still is not nearly ready to replace a human conductor. Mr Choi says the robot's greatest weakness is that it can't hear. “Some people think that conducting is just a combination of hand waving and keeping the beat，” says Mr Choi. But a good conductor needs to listen to the orchestra, so that he or she can correct and encourage the orchestra as it plays. Mr Choi said that once EveR 6 started, “the musicians had no choice but to follow its beats.” He said this created a situation where “the performers have to communicate and ‘sense’ each other to follow the correct beats.” Mr Choi doesn't think robots are likely to replace human conductors. But he believes robots could be helpful in situations like practice sessions where the same thing needs to be repeated many times. 语篇解读：本文是一篇新闻报道。文章讲述了机器人指挥管弦乐队的情况。 1．What is the main disadvantage of EveR 6? A．It cannot keep the beat steady. B．Its movements are not so natural. C．It cannot show emotions like humans. D．It lacks the ability of thinking independently. 解析：细节理解题。根据第三段中“But EveR 6 doesn't think on its own like some advanced Artificial Intelligence programs.”可知，它主要的缺点是无法独立思考。 √ 2．What did Mr Choi mean by saying that “the musicians had no choice but to follow its beats”？ A．The robot is programmed with correct beats. B．The musicians are not allowed to communicate. C．The robot is trained to be strict with the performers. D．The robot cannot interact with the musicians. 解析：推理判断题。根据第四段中Choi说的话可知，音乐家们“别无选择，只能跟着节拍走”，是因为机器人不能和乐队互动交流。 √ √ 3．What is Mr Choi's attitude toward EveR 6? A．Negative. B．Objective. C．Subjective. 　 D．Indifferent. 解析：观点态度题。根据第四段中“The robot was able to present such detailed moves much better than I had imagined”以及“Mr Choi says the robot's greatest weakness is that it can't hear.”可知，Choi分别说明了机器人的优点和缺点。由此可推断出，他对机器人的评价是客观的。 √ 4．Which of the following is a suitable title for the passage? A．Robot EveR 6 conducts an orchestra B．A competition between human and robot C．The power of AI robot technology D．Revive orchestral performances in Korea 解析：标题归纳题。根据第一段并结合文章内容可知，本文主要讲述了机器人EveR 6指挥管弦乐队的情况。故A选项“机器人EveR 6指挥管弦乐队”适合作文章标题。 (二)完形填空 Automation (自动化) certainly has its advantages.
