Homework should be done as soon as you get home from school. If you have after-school activities, the homework should be done first. At the same time, it is fine to allow for a snack break and also to allow for stretching(拉伸的)breaks.

    Also, you should remember that it is your duty to do your homework. Next time, when you want to depend on Mom and Dad for help, please try to find the answer yourself, because you will learn much, much more that way.

When you have a question, especially something about a science or math, don't always turn to your teacher! It is a good idea to try to find the answer yourself. If this doesn't work, you can also look at the materials in the back of the book. They may guide you to the pages you should look at to help you understand the problem.

    Finally, while doing homework, don't think about or do other things. Keep working. Setting a time limit(限制) often helps with this. Different ages decide different amounts of time. 10-15 minutes is good for a child that's aged 6-8. A time of 20-30 minutes is about right for a child aged 9-12. Kids can keep studying for 30-45 minutes from the ages of 13 to 15. This, of course, depends on your abilities to pay attention and stay on tasks.

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.
