Nowadays,more and more students have their own cell phones.Cell phones can increase fun when we are in the school.And it is convenient for us to contact our parents with the cell phones. But,cell phones sometimes disturb our teachers' teaching in the classes.Some students will spend too much time chatting with the other people on the phone.It will certainly waste a lot of money.My suggestion is that students should be forbiddened to use their cell phones in class.And cell phones are very expensive.Students should keep them well by themselves.
