New rules and behavior standards(行为规范)for middle school students came out in March. ①Who are  the  most     excellect student? Middle school uses a new way to decide them. 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 following are some of the new rules.

Tell the trueth. Have you ever copied someone else’s   work on an exam? Don’t do it again. That’s not something an honest student should do. If you have played computer games for two hours in your room,don’t tell your parents you have done your homework.

Do more at school.②Good students love animals and care for others. April is Bird- Loving Moth in China. Is your school doing anything to celebrate?  You should join!That way, you can learn more abaout animals ahd hoe to protest them. When people work together, it makes it more fun for everyone.

Be open to new to new ideas. Have you thought that people live on the moon?Maybe you discover Earth someday. Don’t look down on new ideas. Everyone’s ideas are important. You should welcome them,because new ideas make life better for everyone.

Use the Internet carefully.Try not to look at Web pages that are bad for you.
