　　教学过程

　　Step1. Greet the whole class as usual.

　　Step2. Warming up.

　　Show the picture on the blackboard and ask students what the people in the picture are doing. In Lesson57 we learned what Jenny, Brian and Danny do with the rubbish. Today we’ll learn more about how students help clean up their school.

　　设计思路：通过呈现一些北美国家学生为环保做一些事的图片，让学生切身感受北美国家学生的环保意识，有利于学生对课文内容的理解。

　　Step3. New words.

　　Teach the new words and expressions: less

　　environment

　　waste

　　fix

　　toilet

　　least

　　throw away

　　take out

　　设计思路： 由于本课的新单词较多，学生独立阅读课文较难。通过教新单词有利于学生完成本课的阅读教学。

　　Step4. Listening

　　1． Play the audiotape. Have the students listen to the tape with the following questions and then answer them. Before listening to the tape，Show the questions on the blackboard, let the students master the main idea of the text.

　　Questions:

　　Why do many students in North America want to join “environment club”?

　　What does no-car day mean?

　　What can people do instead of driving a car?

　　How much water will a leaking toilet waste an hour?

　　2.

　　Correct the answer.

　　设计思路：英语新课程标准要求运用“任务型”的教学方法。因此在听录音之前，先呈现要回答的问题，让学生带着问题去听录音，这样学生就会有意识地抓住要听的主要内容，提高学生的听效果。同时，培养学生的倾听能力。

　　Step5. Reading.

　　Have the class to read the text. And point out some important language points of the text.

　　设计思路：英语课堂教学要求全面提高学生的听、说、读、写的能力。本句型中有一些重要的语法点经常出现在练习中。而且学生往往不容易记住，因此教师有必要讲解其中的知识点，并通过举例进一步达到知识的运用。

　　Step6. Discussing

　　Divide the class into small groups. Ask each group to discuss, in English, the following topics:

　　1.

　　According to the reading, what things do North American students do to stop pollution or to make less pollution?

　　3.

　　What can you do to make less pollution?

　　Ask some groups to share their ideas with the rest of the class.
