spreads over cities and villages. It makes people
ill, and may even kill them. Pollution is a danger
to our health.
Betty: And there are so many cars on the roads. They
use so much oil and cause pollution as well.
Daming: But we’re only students. We can’t do anything
about factories and cars.
Betty: It’s no use talking about things we can’t do.
We’ve got 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
Lingling: At a green school, every class collects waste
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.
