With the development of the society, there are too many cars on the streets in our city. 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.,the problem is there because the rubbish collectors do not come often enough to collect the rubbish. the people living here may also be throwing away too much rubbish. We could try to ask people to produce less rubbish. I suggest that rubbish collectors collect rubbish more often as well. I believe that a better environment can be created in this town and we could all work together to achieve it. Your faithfully, Wang Xi,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 become better and better.,1 Write different forms of the words.
