Today, more and more students go to school with mobile phones. Many students say that it’s right to do that. Firstly, it is easier for students to keep in touch with their parents and friends. Secondly, mobile phones can give students useful information for study and make their lives colorful.
However, others don’t think so. They think mobiles make students concentrate less on their lessons. Besides, they often spend too much money on phone calls and sending messages.
In my opinion, it’s convenient for students to take mobile phones to school, because when they meet with danger, they can ask for help. So students should be allowed to take mobile phones to school as long as they use them properly.
