The rules（规则，常规） in American schools
Greetings
You needn’t greet your teachers when you e 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.
