2. 话题：保护环境
3. 时态：一般现在时
4. 人称：以第一人称为主
Less is more
It might be better to focus on one problem and write about it in detail instead of writing about many problems and not providing enough details.
Writing tips
Everyone in this town should play a part in cleaning it up.
To cut down air pollution, we should take the bus or subway instead of driving.
The river used to be so clean.
Let’s take action now!
All these small things can add up and become big things that can improve the environment.
Good sentences
Sample writing
Dear Sir/Madam,
I have lived in this town ever since I was born and I love this town very much.
时态用一般现在时,以第一人称为主
注意书信的格式
多种句型陈述问题
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.
提出产生问题的原因，并给出建议
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
