Listen to learn 1 Listen to the conversation.
What is Zhi Hong’s project about?Her plan is about protecting the seaTape-script 录音材料Fang Zhou is asking Zhi Hong about he science project.
FZ: Hey, Zhi Hong, what did you do for your science project?
ZH: I did something about protecting the sea.
FZ: Protecting the sea from what?
ZH: Well, first there’s pollution, that’s a big problem, and second, there’s over-fishing.
FZ: What’s over-fishing?______________________________________ZH: That’s when people fish too much and the number of fish falls too low. Some fish may disappear altogether.
FZ: Really?
ZH: Yes, now there are too many fishermen fishing in the same place.
FZ: Do you mean that there are more fishermen now than there were before?
ZH: Yes, there are many more. And fishermen today have better technology so they can catch more fish than before._______________________________________________________________________FZ: So there are more fishermen catching more fish?
ZH: Well, they hope to catch more fish, but there are less fish to catch, so they simply can’t.
FZ: That’s bad.
ZH: Yes, and pollution is very bad, too.
FZ: What causes the pollution?
ZH: All sorts, chemicals, plastic, rubbish, oil. It mostly comes from industrial waste from factories and agricultural waste from farming.
_____________________________________________________________________________________________________________FZ: It sounds like a big problem.
ZH: Yes, it is a big problem.
FZ: Has anything been done about these two problems?
ZH: Well, some government departments are trying to deal with the situation.
FZ: Are they?ZH: Yes, some look for ways to reduce pollution, some keep a record of levels of pollution, other departments are responsible for finding where it comes from and punishing people who have broken the law by causing pollution. Of course, often it’s quite difficult to find who’s responsible for pollution.
_________________________________________________________________________________________________________FZ: Yes, I suppose it must be. What about over-fishing? What can be done about that?
ZH: The government tries to control the number of fish that people can catch. In the worst areas they ban fishing completely for a few months at a time so that the fish numbers can grow again. They also try to help people to get other kinds of jobs so there are less people trying to make a living from fishing.
