完形填空

阅读下面的短文,根据所给语境,按要求完成下列各题。

New rulers and behavior standards(行为规范)for middle school students came out in March. ①Who are the most excellent students? 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 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 your homework.

Do more at school. ②Good students love animals and care for others. 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.

Be open to new ideas. Have you ever thought that people could 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.

③Use the Internet carefully. Try not to look at Web pages that are bad for you. You can use the Web for homework. Can’t you find good Web sites for children? Here are some: http://kids. eastday.com  http:// www. chinakids. net. com http:// www. cynet.com
