（2019版）新人教版高中英语必修第三册Unit 4 SPACE EXPLORATION 教学设计.docx

1、Unit 4 SPACE EXPLORATIONReading and Thinking: Space: The Final Frontier文本简析本单元阅读材料探讨的主题是：太空探索。该主题涵盖了太空探索的发展历程及其探索意义。其目的在于促进学生多维度深入了解“太空探索”这一前沿科学研究行为，引导学生理性看待“太空探索”对人类发展的深远意义，从而树立学生正确的科学观。本文是一篇说明文。该文本结构清晰，文章由 5 个段落构成，每个段落主题独立。文本首段始于两个问题，点明了人类进行宇宙探索的初衷，其一是探究宇宙的秘密，这是基于知识认知层面的回应；其二是寻找新的资源，这是基于人类生存层面的考量。

2、第二段从国际视角出发，概述了在探索太空早期所取得的标志性成就；第三段简述了太空探索遭遇的危险及例证科学家坚定探索的决心；第四段聚焦中国在“探空”方面所取得的成果；第五段展望未来，呼应首段，再次点明太空探索的意义及目的。在进行教学设计时，要帮助学生厘清文本的主要内容和内在结构；通过段落内容的解读填补缺失信息句，提炼段落主题大意。在填补缺失信息句方面，教师可以从“一找位置，二寻词汇，三看逻辑”三个层面开展策略指导；在概括段落大意上，如何寻找主题句；在主题句缺失的情况下，如何概写主题句等方面进行方法引导。在教师的引导下，学生延伸思考太空探索的危险和挑战及人类对太空探索可能带来的好处，最终达到内化语言
