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.

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.
Mr. Xi Jinping’s words:
Lucid waters and lush mountains are invaluable assets.
Let’s protect green waters and blue skies and build a better home!
