 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. 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 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? You should join! That way, you can learn more about animals and how to protect them. When more people work together, it makes it more fun for everyone.

     Have you ever quarreled 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 for kids, so try to look at Web pages that are good for you. You can use the Web for run or homework. Can’t you find any good! Web sites for children? Here are some: Http:// kids.eastday.com  Http ://www. China kids. net.com    http:www.Cycnet.com

Do you know why different animals or pests(昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.

  Some birds like eating locusts(蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

  If you study the animal life, you'll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters(猎人). This is because they have the colors much like the trees.

  Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid(液体)when it faces danger. While the liquid spreads over(散开), its enemies(敌人) cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

What’s a blog? A blog is a personal online diary(日记). It’s cool, it’s hot, and everyone is doing it. People talk about it often. Sound like a fashion? In fact, It’s another trend (流行趋势). And the word “blogger” means a person who writes diaries online. Are you a blogger?  

Many bloggers are teenagers who log (进入) onto websites to discuss anything in their lives. Many of today’s teenagers are not afraid to openly discuss everything in their lives. Teenagers complain about their parents and homework. They share diaries, post(发布) songs from the latest bands and show pictures of theirs.
