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.
