Listen and read.
Lingling: After our lesson on the environment, I’m worried about the future. Pollution is our great enemy, and we have to fight it. If the rivers are polluted, farmers can’t use water for their crops.
Tony: And in some places, pollution from factories spreads over cities and villages. It makes people ill, and may even kills them. Pollution is a danger to our health.
Betty: And there’re so many cars on the road. They use so much
oil and cause pollution as well.

Lingling: Do you think we can make our school a green school
Daming: What’s a green school
思 考
新课讲解
Lingling: At a green school, every class collects waste or rubbish which can be recycled or used again. Then the school sells the waste and uses the money to help students in poor areas.
Daming: Nice idea!
Betty: Students at a green school also learn ways to save energy and recycle at home. That means less waste.
Tony: That’s a good idea. Though pollution is heavy now, I don’t think it’s hopeless. If everyone starts to do something, the world will be saved.
