人教版高中英语必修第三册Unit 4 阅读课教学设计和导学案
阅读课：太空-最后的边境（新人教必修三第四单元）教学设计&导学案文本解读该板块以“了解太空探索的发展历程”为活动主题，文章按照时间顺序简要介绍了人类探索太空的历史，共有五个段落，分别叙述了以下内容：（1）人类一直对未知的太空充满好奇心；（2）从20世纪中期开始，美国和苏联在太空探索领域取得了举世瞩目的成就；（3）尽管遭遇了一些挫折和灾难，通往太空之路也充满艰险，但人类探索太空的决心不曾改变；（4）中国的太空探索计划虽然起步较晚，但是发展迅速，成就显著；（5）人类探索太空的脚步会越迈越远，前途也将是一片光明。
除了列举一些著名的历史性事件以外，文章还对科学家和宇航员们不畏困难、刻苦钻研、勇担重任、无私奉献的精神表达出赞美之情。
文本特点该板块的阅读语篇是一篇科普文。
科普文章的读者是大众化人群，而非专业领域的学习者或研究者，因此，这一篇体裁的核心目标在于既要抓住科学方法和科学事实，又要保持语言通俗易懂。
设计理念基于文章主线”the development of space exploration”展开文本阅读，从中穿插深度思考Why was space exploration mainly carried out by the USSR and the US in the 20th century? Why has China made great progress in space exploration in the 21st century? What does the title “Space: The Final Frontier” mean?教学步骤（1）教师首先以一段人类探索太空的视频为导入，让学生大致了解人类太空的发展史，为接下来阅读的展开做好铺垫；（2）学生阅读活动2的四个句子然后阅读课文完成活动2及活动3，此环节教师先引导学生学会找topic sentence，如果没有，学生阅读第40页Summarize the main idea的策略提示，然后再总结段落大意；（3）学生再次阅读文本: I. 通过表格的形式展示出Para 2&4中的人类探索太空的历史，并且思考Why was space exploration mainly carried out by the USSR and the US in the 20th century? 以及21世纪中国航天发生了哪些变化？为什么？该环节主要让学生了解人类太空探索的发展历程及重大历史事件，另一方面帮助学生了解我国在太空探索领域所取得的辉煌成就以及对人类太空探索事业的贡献，从而坚定文化自信，增强爱国情怀和民族自豪感；II. 根据Para3中信息学生可以了解人类为探索浩瀚的宇宙付出了生命的代价，引导学生思考What is the importance of carrying on space exploration? III. 总结Para 5中未来太空探索的目标；（4）讨论文章标题。
