Cars have made the air unhealthy for people to breathe. Black smoke and poisonous gas are given off by factories. Factories also put waste into the river. And wherever we go, we can find rubbish.Now more and more people have realized these problems. I think that governments should close down the factories and develop laws to stop people from driving cars every day. I suggest everyone in this town should help to clean up the river and the streets. We should call on everyone in the town to throw rubbish in the dustbins. I hope the problem will be solved in the near future and our home will bee better and better. 3.处理教材Self Check1的内容。

Dear Mr. Mayor,Thanks for making some time to read this letter. I’m a native here. I think everyone in this city wants to have a bright and beautiful home. But there are some environmental problems in our city. The river used to be very clean, but now the river was dirty. Even the bottom of the river was full of rubbish. People are littering in the river, Factories are pouring rubbish into the river. The air has bee really polluted around here. There are so many cars on the road these days. More and more people driving to work or school today. Factories that burn coal also pollute the air with a lot of black smoke. There is also too much rubbish and waste around our living places. People throw away rubbish like waste plastic in public places. This turns beautiful places into ugly places.To cut down environmental pollutio。
