    We have different kinds of rules in our classroom. As a student we must follow them.

    Students can not bring food into the classroom because or classroom is a place for us to study. The food may make our classroom dirty. And we can't study well when one is eating.

    Don't run or fight in the classroom. It's quite dangerous because we may get hurt(受伤的).

    We need a quiet place for study. Don't listen to music in the classroom. Listening to music may disturb(打扰) others.
