The rules（规则，常规） in American schools Greetings You needn’t greet your teachers when you come into a very big class. If you are late for class, you may go into the classroom quietly. But you should say sorry to the teacher after class. Answering questions Don’t talk when somebody else is speaking. If you have something to say, you have to wait. When someone is speaking, you shouldn’t interrupt him or her. If you want to answer the teacher’s questions, you may stand up and speak loudly. It’s impolite to keep quiet when your teacher asks you questions. If you don’t know the answers, you can say “I’m sorry”. Other interesting rules Some American schools don’t allow students to wear caps, sunglasses or too large trousers. And they can’t bring any bananas to school. The school bags for the students are usually sheer （透明的）, so teachers can find what’s in it easily. 小题1:If you are late for class in American schools, what should you do? ________________________________________________________ 小题2:Is it polite to talk when someone else is speaking? ________________________________________________________ 小题3:When students want to answer the teacher’s questions, what should they do? _________________________________________________________ 小题4:In some American schools, students can’t do any things.
