同课异构教案：八上M3U2

1、 Unit 2. We havent found life on other planets yet.（初中英语外延版八年级上册Module 3 Journey to space ）南宁市第三十一中学 黄玲鲜一、教材分析 本模块以人类探索宇宙的行为为背景引入现在完成时的用法，通过人类对宇宙太空所做努力的描述，强化现在完成时表达意思的功能，开展听说读写教学活动。教学内容为语法的学习和使用提供了必要的感性材料。本模块的中心话题是介绍航天知识，着重介绍了火星探索计划以及宇宙中太阳系的部分知识。要求学生能够了解一点航天知识，学会利用现在完成时描述人类已经实施的太空探索计划。 二、学情分析在前一个模块“

2、Experiences”的学习中，学生初步掌握了利用现在完成时谈论旅游、看电影等经历，学习了现在完成时的一般疑问句及肯定、否定的回答方法。在本模块中，学生将继续学习yet, already, just, recently等词在现在完成时态中的用法, 以及have been to与 have gone to之间的区别。人类探索宇宙，是否真的存在外星人，太空旅行这些一直都是学生们非常感兴趣的话题，学生会觉得有话可说。但是在讨论这一话题时将涉及较多的专有名词，学生掌握的难度较大。所以如果教材内容处理不当，会导致学生有话想说，却无法用英语来表达的尴尬场面。因此在具体安排教学内容时，应注意适当降低难度与
