典例参考

Dear Sir/Madam,
Environmental problems are becoming more and more serious all over the world.
With the development of the society, there are too many cars on the streets. Cars have made the air unhealthy for people to breathe. Black smoke from factories polluted the air seriously. Factories also put waste into the river.
Now more and more people have realized these problems. I think that governments should develop laws to stop people from driving cars every day. I suggest everyone in this city should help to clean up the rivers and the streets.
I hope the problem will be solved and our city will become better and better.
