六、教学过程
教学过程是教学活动的关键，是教师教学思想的具体体现，在本课教学中，我始终坚持以激发学生兴趣，培养学生能力为原则来完成教学过程。
（一） Class Opening
Play an English song:Save the world(设计理念:教师对学生英语学习兴趣的唤起，最重要的是浓烈的学习氛围的创设。通过歌曲展示可以给学生创造一个形象、生动的运动场景，有助于抓住学生的学习兴趣。）
（二）New Lesson
Step 1: :Lead- in & Think about it .
Why do we save the world? Look at the pictures. The rich lands become deserts .Look at the big chimneys. The factory is pouring thick smoke to pollute our air. The air is becoming dirty. The rivers are getting dirty ，too. So Many people are worried because the environment is changing .These changes are serious. So we should do something to help.
Look at the pictures .What is it? It ’s_____. Yes ,is it clean? Is it beautiful? Look at the picture .What’s it? Yes .
When you see a lot of garbage in your schoolyard ,how do you feel? I feel very awful .What should you do?
Ok ,Let’s clean up .Today we study Lesson 43 Let’s clean up!(clean up is ---------)So let’s look at the pictures .Who are they? Do you know? What are they doing? Yes ,they are cleaning up our schoolyard.
(设计理念：联系实际生活与保护环境的关系，培养学生对保护环境的认识，通过生活与教学的联系可以使学生对知识的掌握更加巩固和娴熟。)
Step 2:Read:Group Work :Let’s do it!No.1
Read the lesson and write true (T) or false (F)and find out the reason why it is true or faults .I will give you 3 minutes .Then No.3 in each group comes here to write your answers. The first one can get 2 marks .The others can get 1mark.If someone makes a mistake, I will minus his or her group 1mark.
OK, the answers are the same. Are they right? Do you know about World Environment Day? What is it? When is it? You can find the answers in your text .The one who finds the answer first will get 2 marks.
