Unit 10. Part 3. Protection of the environment.

Dialogue 1.

W: The air in the city is seriously polluted.

M: Yes. I can’t even breathe.

W: Air pollution endangers our health.

M: The government should take steps to solve it.

Dialogue 2.

W: I can’t bear the noise near my house any more.

M: Why? Is it that bad?

W: The road near my house has been being mended for more than half a year, and it is still not completed.

M: Do the other people from your neighborhood complain about it?

W: Yes, most of them do.

M: Why not hold a meeting. I am sure you can come up with some solutions.

Dialogue 3.

W: What a smell. Look at the dirty water in the river.

M: Many industries are polluting the river with waste and sewage.

W: What’s more fertilizers, herbicides and pesticides used for lawn care can run off and contaminated the water.

M: If water contamination continues human beings will suffer severely.

Dialogue 4.

W: How to control environmental pollution for the sake of people’s health?

M: There are many methods adopted by the government. But it is pretty hard.

W: Why is that?

M: Some depurating devices are not so effective. Some effective devices are so expensive that manufacturers can even afford.

W: Then why not consider reducing some heavy industries?

M: Almost impossible. China is a developing country and needs heavy industries to increase its GDP.

Dialogue 5.

W: What technology will help with pollution control?

M: Well, for example I have recently read an article about using certain types of bacteria to help control some pollution problems.

W: How could that be? I thought bacteria just caused illness.

M: That’s not true. Bacteriologists have identified certain strains of bacteria that eat petroleum products such as oil and gasoline.

W: That sounds strange. How does it work?

M: They ingest the petroleum and excrete hydrogen and oxygen leaving a clean environment behind them.
