Listening
Listen again 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.
Reading task
Betty: And there’re so many cars on the road. They use so
much oil and cause pollution as well.
Daming: But we are only students. We can’t do anything about
factories and cars.

to think of things we can do!
Daming: Such as…
Lingling: Do you think we can make our school a green school
Daming: What’s a green school
Reading task
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.
