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 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.
Environmental problems are becoming more and more serious all over the world.
开篇点题
Factories
说明原因
范文赏读A
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.
提出建议
寄予期望
Dear Sir/Madam,
I have lived in this town ever since I was born and I love this town very much.
I think that there are beautiful areas in this town, but there are also areas that aren’t attractive, like the rubbish disposal areas at the bottom of our apartment blocks. There is rubbish coming out of the bins, and flies, cockroaches and rats running all over the rubbish. It is unpleasant to look at, smelly, and it makes the environment very unhealthy.

多种句型陈述问题
范文赏读B
The problem is that 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 should all work together to achieve it.
Yours faithfully,
Wang Xi

More and more people get to know it's important to protect our
living environment. As students, it's our duty to do something for
the earth.
On the one hand, there are many things we can do. we should plant more trees and go to school on foot or by bike. Besides, we are supposed to turn off the lights when we leave the room. On the other hand, we shouldn't do a lot of things. To begin with, we shouldn't cut down trees. Then,we had better not go to school by car. What's more, we aren't expected to spend too much time watching TV or surfing the Internet.
In a word, if we try our best to protect the environment, the world will become more and more beautiful.
