New rules and behaviour 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. Here 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! That's not honest. If you have played computer games for two hours in your room, don't tell your parents that you have done homework.

Do more at school. Good students love animals and care for other people. April is Bird-Loving Month in our country. Is your school doing anything to celebrate? You should join! That way, you can learn more about animals and how to protect them. Have you ever quarreled（吵架）with your teammates when your basketball team lost? Only working together can make your team stronger. 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? Perhaps you'll discover（发现） Earth II someday. Don't look down at anyone. Everyone's ideas are important. You should welcome them, because new ideas make life better for everyone.

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 aren't for kids, so try to look at Web pages that are good for you. You can use the Web for fun or homework.
