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

Middle schools are going to use a new way to decide who the top students are. The best students won't only

have high marks. The following are some of the new rules.

     Tell the truth. Have you ever cheated (作弊) in an exam? Don't do it again! That's not something honest

students should do.

     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! In that way, you can learn more about

animals and how to protect them.

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

earth in space in the future. Everyone's new ideas are important.

     Protect yourself. Has a thief ever taken money from one of your classmates? Don't let it happen to you.

If you have to go back home late, you should let your parents know.

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

aren't for kids, so try to look at the good web pages. You can use the web pages for fun or homework.
