1. LEARNING ABOUT LANGUAGE 部分学习本单元重点词汇和语法项目。词语学习部分采用给出词义而让学生从课文中找出与之匹配的词，然后用所找的词汇完成第二个练习中的短文，以及用课文中意义相近的词汇替换练习三句中划线部分。通过这三种练习帮助学生理解并能熟练应用课文中所学的词汇。语法部分通过从课文中找同义句引出动词的-ing 形式，教师此时可引导学生找出其他的句子，以启发学生理解-ing形式的句法功能。练习二通过模仿例句，用-ing形式做主语代替动词不定式改写句子。练习三要求学生连接短语造句，让学生学习-ing形式作宾语的用法，并列举后面接动词-ing形式作宾语的动词。练习四则训练学生v-ing形式在实际生活中的应用能力。练习五则设计了一个游戏以丰富学生的想象力。

2. USING LANGUAGE 部分综合训练学生的听说读写能力。第一部分读写结合，学生先阅读文章，文章写的是

Organic Farming or green food,读完后要求学生写一个摘要。在此教师要首先强调写摘要时学生一定要抓住文章的主题并且运用所学的重要词语。听力部分通过回答问题来提高学生的理解能力和理解的正确性。Reading, speaking and writing 部分把读，说和写有机地结合在一起。假设你是一个“绿色食品”

farmer，通过背景阅读，你要有充分的理由，利用所提供的句型，以对话的形式说服他人购买你的食品。最后为你的食品设计一个有说服力的广告。
