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

A sample writing
Dear Mayor,I’m glad to write this letter to you. I’d like to talk about the environment in our city.Our city is not as beautiful as before. Environmental problems are becoming more and more serious. The river is dirtier. People are throwing litter into the river or in public places like parks. This is turning beautiful places into ugly ones. Factories are putting waste into the river and they burn coal, which also pollute the air with a lot of black smoke. And most of us ride in cars to school even if they live close to school. I think it is time to play a part in saving the earth.

First of all, we should let more people know the importance of environmental protection. We’re supposed to save water and energy in our daily life. Second,to cut down air pollution, we should ride a bike or walk to school instead of riding in cars. If it’s far, we can take the bus or subway. Third, we shouldn’t throw litter here and there. We should put it in the bins. As for waste pollution, we should never take wooden chopsticks or plastic forks when buying takeaway food. We can also use reusable bags instead of plastic bags. What’s more, the government should close down the factories that are putting waste into the river or giving out a lot of black smoke.The earth is our home and we have the duty to take care of it for ourselves. So I hope that you can take my advice. Thank you.
