Beijing leading schools say “No” to students’ mobile phones.

Three reasons make some leading schools in Beijing discourage middle school students from bringing mobile phones to campus(校园).

First, it is dangerous for children to bring valuable mobile phones along to school for it is possible for them to be lost during physical exercise and other activities and may cause unnecessary trouble to teachers.

Second, mobile phones are bad for students’ studies. Many teachers complain(抱怨)that some students have phone calls in class, disturbing(打扰)themselves and others.

Third, mobile phones serve as a hotbed for students’ vanity(虚荣). A new Grade One senior high school student in a leading school asked his parents to buy a 4000-yuan colored-screen mobile phone, which turned out to be his fifth one ever since he entered the middle school.

Most presidents and teachers in leading schools of Beijing thought that IC telephones on campus have made it very easy for students to get in touch with others, so middle school students should not bring mobile phones to school at present.

Scientists would like to place a huge mirror in space above the earth. It might be sixty miles wide. It would be used to catch the rays(光线)of the sun. It would direct the sun's rays upon the earth as a child might do to make sunlight dance on the wall with a hand mirror.

Why do they want to do this? The sun's rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts(霜冻)which might come at night and hurt fruit crops. They could melt(融化)dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed.
