     New rules and behavior standards (行为规范) for middle school students came out in March. Middle

school is going to use a new way to decide who the top students are. The best students won't only have

high marks. They will also be kids who don't dye (染) their hair, smoke or drink. The followings are some

of the new rules.

     Tell the truth. Have you ever copied someone else's work on an exam? Don't do it again. If you have

played computer games for two hours in your room, don't tell your parents you have done homework.

     Do more at school. Good students love animals and care for other people. You should learn more about

animals and how to protect (保护) them. When more people work together, it makes it more fun for

everyone. Only working together can make your team together. Be friendly to the people you are with. Try

to think of others, not only yourself.

      Be open to new ideas. Have you ever thought that people could live on the moon? Maybe you'll discover

earthⅡsomeday. Don't look down new ideas. Everyone's ideas are important. Protect yourself. Has someone

ever taken money from one of your classmates? Don't let it happen to you. If you have to go home late, you

should let your parents know.

      Use the internet carefully. The Internet can be very useful for your studies. But some things on the

Internet are bad for kids,so try to look at Web pages that are good for you.
