Unit 2 Looking into the future Using Language Ⅱ P20-21 课件-2025-2026学年高二英语人教版选择性必修第一册

该高中英语课件围绕“新技术影响”主题，聚焦议论文读写能力培养，涵盖结构分析（议题引入、优缺点讨论、观点表达）、语言特征（指示词识别）及写作实践。课堂通过图片思考（self-driving mode）、观点分享（支持/反对新技术）导入，从阅读分析无人驾驶争议文本过渡到AI工具作业写作任务，构建“输入-分析-输出”学习支架。 其亮点在于融合语言能力、思维品质与学习能力培养，通过辩证分析Amish人生活与互联网优势，引导学生掌握举例、因果推理等论证方式；提供正反观点写作模板、句式积累及范文（如支持AI使用强调“即时信息获取”，反对则突出“批判性思维缺失”），帮助学生构建逻辑清晰的议论文。对学生提升读写逻辑与批判性思维，对教师提供完整教学资源，便于高效实施。

Assignment Should Students Use AI Tools for Homework? 随着DeepSeek等人工智能应用的流行，越来越多的学生频繁使用AI来完成作业。校英文报就此现象展开讨论，请你投稿发表看法。内容包括： 1. 你支持还是反对使用AI完成作业？ 2. 简要说明你的理由。 Practice 写作任务 Should Students Use AI Tools for Homework?

In today's digital era, AI tools like DeepSeek have become increasingly prevalent in education. While some worry about over-reliance, I firmly believe that when used properly, these tools offer valuable academic support. First, AI provides immediate access to relevant information, helping students overcome learning challenges efficiently. For example, when struggling with complex math problems, learners can receive step-by-step AI explanations instead of remaining stuck for hours. Moreover, by combining AI assistance with traditional study methods, students can personalize their learning pace while developing critical thinking skills. However, moderation is key. Students should analyze AI-generated solutions thoroughly rather than copying them blindly. With proper discipline, AI not only makes learning more efficient but also fosters independent problem-solving abilities. When used as a supplementary tool rather than a shortcut, AI can significantly enhance educational outcomes. 32 Possible Version 2: Opposing AI Use (Cons) Should Students Use AI Tools for Homework? As high school students, we cannot deny the convenience AI tools like DeepSeek bring to our studies. However, we must recognize that excessive reliance on them may do more harm than good to our academic development. What concerns educators and students alike is how AI dependency fundamentally alters the learning process. When we command AI to generate instant answers, we sacrifice the opportunity to engage in critical thinking - the very skill that standardized tests and future careers demand. Research shows students who overuse AI for homework score 15-20% lower on exams, proving that instant access to answers doesn't translate to knowledge retention. Furthermore, in the absence of genuine effort, we fail to develop problem-solving strategies or the ability to concentrate on complex tasks. My physics teacher often warns that students who rely on AI solutions struggle with experimental design, as they haven't developed the necessary analytical skills through practice. Therefore, while AI can be a useful reference tool, we must resist making it our first choice for completing assignments. After all, genuine learning occurs only when we concentrate on the thinking process instead of seeking instant solutions. 33 Thank you! null, track 9 197366.55 $$
