We students should be our own masters.We need rules to regulate us.Here are some rules that may be helpful for us:
1.Students can't throw rubbish.If someone breaks the rule,he must clean our classroom for a week.
2.Student can't talk in class.If someone talks,he has to tell a story to the class.
3.Students can't say dirty words.If they do,they must do fifty sit-ups.
4.Students must finish their homework.If they don't,they have to do it three times later.
