Ⅰ.Materialanalysis
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。

对于本课出现的定语从句和情态动词的被动语态，老师只要让学生理解句子意思即可，不要求深度解释。
为了让学生便于理解，老师可以简单地用“把”字句和“被”字句来解释被动语态。

并列句是本课的学习重点。
老师如果觉得用英语讲解学生难以弄明白，不妨就用汉语表述。
但是“compoundsentence,conjunction”这些术语要学生能听懂才行，学生以后会经常听到。
老师最好将所举的例子板书出来，以加深印象。
老师可以自己（最好让学生）做动作同时辅以构词法来讲解:
agree（v）+ment=agreement（n）dis（不）+agree（v）+ment=
disagreement（n）。
