Unit2SavingtheEarthTopic3Whatcanwedoathometoprotecttheenvironment?SectionBⅠ.Materialanalysis本课是第二单元第三话题的第二课时。主活动是1a。1a通过Jane告诉Michael怎样才能成为一个环保人士来继续学习提建议的表达方式，同时也向学生继续传递更多的环保理念。1b是检验学生的听力理解能力，1c通过完成表格，来巩固1a的内容。2要学生根据句意来进行词语匹配和图文匹配。3要学生根据上下文和首字母完成短文，这是对学生综合能力的考查。短文不仅复习了已学的连接词，还学习了新的连接词：afterall。4这个小组活动实际由两部分组成：调查和汇报。在做这个活动时，要求注意重读、不完全爆破和连读。目的在于纠正中国人学英语的薄弱环节：不能在交流中得体地运用重读、不完全爆破和连读。本课的各个环节都在传递环保理念。这对学生的环保意识的培养是非常有意义的。4这个活动要完整地体现，要比较长的时间，建议在课堂内完成语音语调部分即可。其它环节可在下次课的复习环节进行，还可以把其中的某些环节作为家庭作业。如：让学生把自己的环保行为列成清单。这样，下次课做调查时，就可以提高课堂效率。Ⅱ.Teachingaims1.Knowledgeaims：掌握本课的重点词汇和短语，继续学习并列句和提建议。2.Skillaims:掌握更多的提建议的表达方法。
