Air pollution
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 the
water for their crops.
Tony: And in some places, pollution from factories spreads over
cities and villages. It makes people ill, and may even kill
them. Pollution is a danger to our health.
Betty: And there’re so many cars on the roads. They use so much
oil and cause pollution as well.
Listen and read.

Lingling: Do you think we can make our school a green school
Daming: What’s a green school

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.
