Teaching Procedure:
Class Opening:
1. Check the homework.
2. Ask two or three students to read aloud their written proposals to their parents or neighbours. Encourage others to add their own suggestions.
Student Book:
Step 1. Lead in: What kinds of rubbish do you often throw every day? Can you name them? What can be recycled? Ask the students to have a discussion about the kind of rubbish and at the same time new words can be taught by talking about some given pictures.
Step 2. Play the audiotape. Ask the students to listen to the tape while thinking about the question:
What makes the most garbage?
Step 3. Immersion Reading:
1. Have the students read the dialogue quickly and finish Ex.2 in the activity book.
2. Read the dialogue carefully again and have a further study about it. Encourage the students to solve their problems in the reading by co-operative learning.
Step 5. Focus Explanation and Practice:
In order to help the students understand the dialogue correctly and master the mastery contents, according to their study, I’ll explain and practice some of the following language points:
1. Jenny has emptied two bags of garbage onto the floor.
empty 可作形容词或动词,意思是”空的;倒空”.
E.g.  There is an empty bottle on the table.
Can you empty the plates for me?
2. Can I help you sort it?
◆ 提供帮助常用句式: Can I help you?  / What can I do for you?  答语: Yes, please. / No, thanks.
◆ sort 可作名词或动词, 意思是”类;分类”。
E.g. What sort of people are they?
We must sort out the bad apples from the good.
3. That’s everything that isn’t glass, metal, plastic or paper.
that isn’t glass , metal, plastic or paper是定语从句，用来修饰先行词everything，关系代词只能用that, 不能用which.
4. Good heavens! So much garbage!
good heavens意思是”天哪”,表示惊讶、不信等。
5. That’s the same weight as a small car!
the same …as意思是”和……一样”。 same前必须加 the。For example：
They have the same population（人口） as we do.
反义词组为 be different from / than/ to…”与……不同”。
Step 6. Play the audiotape. Ask the students to listen and repeat, then act out the dialogue in groups of three.
Class Activity: Come to “Unit Project”.
1. Ask the students to read the structions of the project with some
questions, such as: What did this project ask you to do first? Why? Help them make clear the specific requirements, goals and expectant result of the project.
2. Collect the garbage which the students have picked up in the school yard and their neighbourhood.
3. Divide the class into small groups. Provide each group with five empty bags and some of the garbage that has been collected. Ask students to sort the garbage into separate bags-- paper, plastic, metal, glass and others. Require them to use their English vocabulary.
4. Compare numbers of the garbage which they’ve sorted.
5. Have students work in the same groups or in new groups. Each group will discuss and make a poster about what things they can do to help reduce pollution in the world.
