Dear Tom,

Thanks for your last letter. You want to know the rules in our school. Now let me tell you about them.

We can’t arrive late for class. We can’t talk loudly in class. We should keep quiet.

When we meet our teachers on our way, we should say hello to them. We can’t eat or drink in class, and we can’t listen to music or play games in class.

Yours, Li Ming
