Interviewer: Today we’re talking to Jason and Susan about environmental problems.
Jason and Susan, can you tell us about some of the problems you’ve seen.
Jason: I think one problem is that the air is badly polluted. I hardly ever see blue
skies anymore.
Susan : Yes, and I used to see the stars clearly.
Interviewer: What do you think has caused this problem
Susan: Well, there are more cars on the road these days.
Jason : And factories that burn the coal also pollute the air with a lot of black
smoke.
Interviewer: What other problems do you see
Susan: I guess there’s too much rubbish and waste in the streets.
Jason: Yes! Every day people are throwing away things like wooden chopsticks,
plastic bowls and plastic bags.
Susan: They’re also littering in public places, for example, during picnics in
parks.This is turning beautiful places into ugly ones.
Interviewer: You’re right. These are serious problems for our environment. Next, let’s
talk about the things we can do to help.

Jason and Susan are talking about some of the environmental problems they have seen as well as their causes and solutions.
One problem is that the air is badly polluted. They used to see the stars clearly. Now, they hardly ever see blue skies anymore. That’s partly because there are more cars on the road these days. What’s more, factories that burn coal pollute the air with a lot of black smoke. To cut down air pollution, they think people should take the bus or subway instead of driving. Besides, it’s a good idea to ride a bike which also does good to health.
