    I want to make a school rule. It is“…”

参考范文一

     I want to make a school rule. It' s “Don' t take mobile phones to school.”

     Many of my classmates take mobile phones to school. They use them to play games. Sometimes they send messages to each other in class. Sometimes they read novels at night and often feel tired and sleepy in class the next day. Sometimes they even use phones to cheat. So I think it' s bad for students to take mobile phones to school. It affects not only themselves but also other students. What' s more, the students with phones may not be concentrated on their studies. Phones cost their parents money. （90words）

参考范文二

     I want to make a school rule. It is “Don' t take mobile phones to school.”

     Phones are more and more widely used, but in my opinion it' s not necessary for students to take mobile phones to school. I still remember one day in a math class, our math teacher was explaining a math problem when one of the boy students' phone rang. All the other students turned to him. The teacher had to stop.

     It not only affected the teacher but also affected ourselves in class. On the other hand, it costs parents money to buy the phones and they have to pay for their children to use the phone. (94 words)
