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.

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.

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

Dear schoolmates.
I am Li Yang from the Students’ Union. We’re having an activity of being a good student. First of all, we must love our country and home. We should be honest and keep our promise. And we should also be friendly to the people around us. Secondly, it’s our duty to study hard, and we should try our best to achieve our dreams. Next, taking exercise can make us keep healthy. After that, we are supposed to show love to nature and protect the environment. Animals are our friends, so we should get on well with them. What’s more, we should get into the habit of taking an active part in all kinds of activities, such as tidying up the classroom and helping our parents with housework.
Come on! I believe we can make it.
