(3)What can we do to protect the nature?

(Attention: Ask students to discuss the above three questions in groups and then share their answers to the whole class. Answers will vary.)

2. Ask students to work in groups of four and let students discuss the pollution they know.

3. Ask each group to summarize their discussion using thinking map (e.g. webbing chart).

4. Show the pictures of different kinds of pollution to students and let them

learn some new phrases about pollution.

5. Ask students to think about the following two questions individually and then encourage some of them to share their opinions.

(1)Do you know what caused the pollution?
