仁爱科普版九年级上Unit 2 Saving the earth. Topic 1 Pollution has causestoo many problems.同步练习1

    Many years ago, people lived a hard life. They couldn't use modern machines, because there was 1 one at that time. Today people have a better life but there are new problems. One of biggest problems is it has 2 our rivers and lakes dirty. It kills our fish and affects our 3 water. We call it water pollution. Noise pollution makes us talk more 4 and become angry 5. Air pollution is the most serious kind of pollution. It affects all living things in the world. Machines and factories 6 our air every day. Sometimes the pollution is so 7 that it is like a blanket (毯子）covering a city. Many countries are making new laws to reduce pollution. We must clean 8  water before we 9 them into some place. We need to do many other things to protect our environment. We must put rubbish into dustbins 10 throwing them about. We can go to work by bus, on foot, or with friends in a car. If we do like that every day, our environment will be better.

— What about putting on a short play?

— I've got a pain in my throat.

A: Where have you been, Li Hai? I called you, but you weren't in.

B:

A:

B: I found that the factory was pouring waste water into the river near it. Lots of fish have died.

A:

B: Do you think “Greener China” can do something?

A:  if they know about this thing, they will prevent it. Let's write to them at once.

B:  I think everything will become better.

— I don't think so. Now          the young           the old can speak some English.

      Our living environment is being polluted faster than before and it seems nobody can prevent it. Time brings us more people, and more people bring us more industry, more cars, larger cities and growing use of man-made materials.

      How can we understand and solve this problem? The fact is that pollution is caused by man —by his desire (欲望）for a modem way of life. So we are often ready to offer everything: clean water, good food, our health and the future of our children. There are more people from the countryside moving into the cities and enjoying the modem society. But as the technological momentum (势头) has grown in the last twenty years, pollution has become a serious problem.

      Now we have to stop to ask ourselves where we are going and why. It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I've got some good news and bad news. The good news is that we're going at 530 miles per hour. The bad news is that we're lost and don't know where we are going.” The sad fact is that this problem becomes a true story when speaking of our modem society.

— I agree with you. It may make people go         .

—They may cause         .
