Dear Sir or 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 ploblem is there because 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 could all work together to acheive it.
Your faithfully, Wang Xi
