Ⅰ. Material analysis

本课是第二单元第三话题的第一课时。主活动是1a和2。1a 通过记者采访Jane，询问有关Jane 在环保组织的活动，引出话题内容：如何做一个环保人士。通过介绍在生活中如何践行环保行为，自然地用到本话题的功能意念：提出建议。在提出建议的同时，又引出本话题的语法：并列句。1b是个难度比较高的听力任务。它不是单纯地考查听写，而是要求学生在听懂内容的基础上，对材料进行归纳之后再填空。1c是用第一人称来转述1a的内容，旨在向学生传播环保理念。2是针对并列句而设计的专项语法训练。3a和3b是在考查学生的垃圾分类意识之后，再通过听对话来进行验证。4再次让学生对垃圾进行分类，以此来培养学生对垃圾再利用的环保理念。通过学习本课，可以增强学生的环保意识。培养学生在写作时运用连接词写出比较连贯的句子的能力。 Ⅱ.
