一、本单元教学内容
本单元的话题是保护环境，主要让学生对环境破坏有一个直观的认识，从而激发学生强烈的社会责任感和对未来发展的思考。1a-2c是一个听说链，是section A 的基础，让学生对环境污染的类型有一个初步的了解，同时谈论了一些解决空气污染和垃圾污染的方法，并为接下来的学习做好内容和词汇上的准备。3a-3c 是阅读任务，介绍了人类捕捉鲨鱼获取鱼翅，破坏生态平衡的情况，文章内容紧扣单元话题，呼吁人们保护鲨鱼，渗透了对学生的情感教育。Section B 进一步展开谈论如何保护环境。Section A 主要谈论保护地球的各种方式。2a-2e是阅读部分，用了三个有同样前缀的词语 rethink,reuse,recycle 来作为文章的标题，介绍了三个在怀抱方面有突出贡献的人物以及他们的做法，让学生在理解的基础上针对相关话题发表自己的看法。3a-3b 首先通过填写表格让学生思考自己周围的环境情况，为写作提供素材，让学生在头脑中形成此类写作的相关框架。
