We have many rules around us. We also have many rules in school. We should be nice and polite to teachers andclassmates. We must be on timefor school. In class we must keep quiet. We should raise hands before we speak.Rules keep our school in order. We should obey the rules so we can have a goodlearning environment.

There is a school rule that myclassmates often break. That is: don't bring phones to school. But recently oneof my classmates lost her phone in school. Our teacher Mr. Wang (warned) said:"If I find your phone in class, I will "help" you to keep ittill the summer holiday."  I thinkit is a good rule  because we will not lose phones in school. Iwill surely obey the rule.
