( )教师活动：让学生快速浏览题目，猜测教授会否定哪些观点。学生活动：快速浏览，对对话内容有所了解。（设计意图：读前活动让学生大致了解听力内容，激发学生的背景知识，引发学生对此话题进行思考。采用泛听的方法，不必听懂文中的每一个单词和句子，为随后的听力活动做准备。）Task2 . Listen to Part 2. Finish the choice.(5mins)1.

Make it a better placeFor you and for me and the_ human raceThere are people _If you care enough for the livingMake a better place for you and for me.(设计意图：学生做了三到四遍的听力重复，倍感枯燥。课堂的气氛也比较沉闷。这时穿插唱歌无疑起到了很好的调节作用。而让学生跟着录音唱，又把听力材料的细节相结合，连明星都呼吁保护地球，我们普通人更义不容辞，更加巩固了学生们对于本材料的认知。)Task 2. Debate: Now in groups discuss and have a debate whether we should do something about global warming. Students may have various opinions. Use some of the phrases listed below or any others you know about agreement and disagreement.A : We shall do something about global warming.B: We shall do nothing about global warming.(设计意图：本环节是整节课的升华，听力是口语的活动的示范。形式多样的口语活动充分打开了学生的思路。他们发挥自己的创造力，口头抒发各自的思想和感情。本课最终的落脚点是在保护环境的情感主题上。)Step 5 Review and Homework（2mins）Review what we have learned in the class and write a poster(海报)about this topic.(设计意图：让学生运用本课所学语言知识参与到写作中，通过实践活动完成输入-输出的过程，去发展英语语言与写作能力。把所学知识运用到实际生活当中，努力扩大学生的知识面，培养学生在生活中学英语、用英语的语言素质,在生活中提高运用英语的能力。同时增强学生保护地球、爱护环境、节约能源的意识。)Step6课后评价用激励性语言评价各小组在
