[00:04.55]Unit 7 The Sea Lesson 2 Protecting the Sea

[00:10.58]Exercise 3

[00:12.43]Listen to the conversation.

[00:14.62]What is Zhi Hong's project about?

[00:18.87]Fang Zhou is asking Zhi Hong

[00:21.89]about her science project.

[00:24.48]Hey, Zhi Hong, what did you do

[00:26.70]for your science project?

[00:28.16]I did something about protecting the sea.

[00:30.46]Protecting the sea from what?

[00:32.81]Well, first there's pollution,

[00:34.77]that's a big problem,

[00:35.93]and second, there's some over-fishing.

[00:38.56]What's over-fishing.

[00:40.47]That's when people fish too much

[00:42.39]and the number of fish falls too low.

[00:44.93]Some fish may disappear altogether.

[00:47.12]Really?

[00:47.98]Yes, now there are too many fishermen fishing

[00:51.22]in the same place.

[00:52.45]Do you mean that there are more fishermen now

[00:54.28]than there wre before?

[00:56.02]Yes, ther are many more.

[00:57.61]And fishermen today have better technology

[01:00.15]so they can catch more fish than before.

[01:03.12]So there are more fishermen catching more fish?

[01:06.77]Well, they hope to catch more fish,

[01:08.98]but there are less fish to catch,

[01:10.74]so they simply can't.

[01:11.97]That's bad.

[01:13.45]Yes, and pollution is very bad, too.
