人教版九年级Unit 13 We're trying to save the earth!-Section A Grammar focus 4a—4c-ppt课件-(含教案+素材)-部级优课-(编号：904f9).zip

一教材来源：人民教育出版社 九年级全一册 Unit 13 We are trying to save the earth. 根据本单元内容所设计的一节关于环境保护的复习课。 Protecting the Environment 二设计思路：本单元的话题是“保护环境， ”主题图有四个图，分别是噪音污 染，空气污染，水污染，废弃物污染等。这些话题一方面是人 们比较关注的话题，另一方面，应该也是中考比较热门的一个 话题。所以，让学生复习并掌握这个话题的熟练应用，非常重 要。同时也激发学生强烈的社会责任感和对未来的发展的思考。 三教材分析：本单元以“保护环境”这个话题贯穿整个教学单元。并通过一 系列的图片，让学生认真观察，认识到环境保护的重要性。 SectionA 和 Section B 两部分，通过系列活动和两篇课文，从 各个层面说明并渗透着环境保护的重要性。 四，学情分析：我所担任的这个班是一个 B 班，学生的基础相对较差，尤其是 英语学科，大部分学生已经失去了对英语的学习兴趣。上课时， 只有部分学生能和老师进行互动，所以，平时在教学中，尽量 能使教学内容简单化，兴趣化，使更多的学生能参与到课堂活 动中来。关于环境这个话题的复习，一方面是应对中考，另一 方面能激发这些学生学习英语的兴趣，进一步认识到环境保护 的重要性。 五教学重点：让学生掌握与环境污染和环境保护相关的词汇和句型，同时引 导学生关爱动物，保护环境。 六. 教学难点：通过系统复习，让学生能熟练写一篇关于保护环境话题的作文。 七教学反思：这节课的话题是 Evironment,环境保护，而且是一节复习课。 环境问题是人们近几年比较关注的话题，也是中考应该涉及的 一个话题。在七，八，九三册课本上都涉及到此方面的内容。 本节课我从 Warming up 开始，直入话题，中间涉及到几个有 关词汇复习的 Brainstorm,目的是让学生复习和环境有关的一 些词汇和句子。然后围绕环境问题，给学生 Tasks,进行讨论， 课堂活动气氛比较活跃。我认为比较成功的一点，中考链接部 分，我把课本中的短文拿来，进行设空，变为一篇完型填空题， 使学生利用所学到的知识很顺利的完成了一篇完形填空题，收 到了很好的效果。最后，利用本节课所复习的内容，让学生写 一篇关于环境保护话题的作文。不足之处，一个可能容量较大， 部分学生可能不能完全吸收，另一方面，句子练习部分还应该 和中考题型挂钩，完全按中考二卷第一大题，完成句子模式， 可能效果会更好。 中考英语话题复习中考英语话题复习 EnvironmentEnvironment The earth is badly polluted.
