I think that middle school students carry mobile phones to school is right, because it is easy to talk with parents and classmates.And it is fashion. But it has some shortcomings. Middle school students is little, they like to vie with others or play games. So ,carried phones to school has good and bad.If we believes middle school students, carried phones to school is good .If no ,it is bad. But I am a middle school student,I think carried mobile phones to school is right, it is better than the bad things.So I agree with it.
