In many middle schools, it's quite common to see some students using mobile phones here and there. Though some schools forbid students to use them at school, many students still think they have the right to use mobile phones.
I don't think it is necessary for us students to use mobile phones to keep in touch with each other. We all know mobile phones give unpleasant noise when we are having a lesson.Besides, using mobile phone costs a lot of money. We are students. Our main task is to study. So we should put away our mobiles phone and focus our attention on studies.
