New rules and behaviour standards (行为规范) for middle school students have come out. The 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 smoke, drink or dye (染) their hair. The following 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 something that 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 homework.

Do more at school. Good students love animals and care for other people. April is Bird Loving Month in China. Is your school doing anything to celebrate it? You should join! That way, you can learn more about animals and how to protect them. When more people work together, it is more fun for everyone.

Have you fought 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? Maybe you’ll discover Earth II 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.

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 good for kids, do try to look at Web pages that aren’t good for you. You can use the Web for fun or homework. Can’t you find any good Web sites for children? Here are some: http://kinds.eastday.com / http://www.chinakids.net.com / http://www.cyenct.com
