Chapter Two Pollution FightersI.章节分析（一）综述本单元的Reading部分的文章是关于“树和环境”。
通过一名中学生采访科学家来了解“树”对环境保护所起的作用。
“污染”问题是一个旧话题，在6B Module 1The Natural Elements和教材后面的Project 1 The Environment 都谈论到环境与污染的问题；7A Module 3 Natural Elements Unit 4 Forests and land中谈到了森林，实际上就是谈树的作用和用途。
其中的大部分内容都是我们的学生很熟悉的，所以老师在引入新课时，可以从学生们熟悉的话题“森林”谈起，很自然的进入新课内容。
本单元的Listening部分也是围绕主题，通过Completing a notice的形式，进一步让学生了解树的作用，从而积极投入到“植树战役”中去。
Language部分介绍了现在进行时(the present continuous tense)的用法。
Speaking部分围绕本课的主题讨论How to fight pollution我们可以把这部分内容放在Post-reading环节，让学生进行讨论。
Using English 部分(The index) 老师可以告诉学生the index 与the contents page 都可以帮助我们快速了解一本书的信息，只是the index 的排版大部分在书后，而且是以字母循序排列的，有主题，比较详细而the contents page 的排版在书的前面，按页码排序。
Writing部分是为学校报纸写一篇有关工人们是如何建造一个sitting-out area的文章。
（二）教学目标1. 知识目标1）词汇：掌握本章出现的生词。
2）语法：能熟练运用现在进行时的陈述句，一般疑问句，特殊疑问句。
3）功能：能和同学，老师表达自己的思想。
4）话题：能谈论“抗污染”这一话题。
2. 能力目标1）听：通过听录音材料来培养学生捕捉特定信息的能力。

II. 教学设计：1. ReadingStep 1 Pre-reading1)老师可以通过复习旧句型：What can we get from forests 引出本单元的主题。
然后让学生根据图片一问一答做 pair work，来了解 What good are trees 当然除了老师提供的图片以外，也可以让学生根据自己了解到的知识自由发挥。
2)老师与学生一起得出结论：Trees are very useful and important. 老师接着问学生：What else do you know about trees How long do trees live 然后让学生来做一个与树有关的quiz。
通过这个quiz让学生知道 Trees are pollution fighters.老师还可以充分利用教参中的Notes来帮助学生进一步了解树是如何与空气污染、水污染和噪音污染作斗争的。
同时帮助学生解决部分Reading中的生词，如：chemical, produce, release, oxygen, nasty等等。
Step 2 While-reading（这是本课的重点部分）1)第一遍阅读文章，要求学生根据上下文的内容和线索猜测词意。
2)第二遍通读全文，理解文章意思，并完成Ex. D (page 18)、Ex. E (page 19)。
提醒学生阅读时注意阅读方法的使用。
比如，在做Ex. D时，使用scanning即跳读的方法寻找具体问题的答案。
在做Ex. E时，使用skimming即略读的方法，注意文章中的主题句和关键句。
3)听课文录音。
