Mobile phones are becoming more and more popular not only with adults but also with students. However, they also have become a problem for middle schools in the last few years.

Some children have got mobile phones as Christmas or birthday gifts, and more will ask their parents to buy phones for them.

Many students like mobile phones because they are easy and quick. Some parents feel it convenient because they can get in touch with their children. Some teachers think using mobile phones is a distraction(分心的事)to students during school hours and mobile phones also give them much trouble in their classrooms. Sometimes students send phone messages to cheat(作弊)during exams. A new study says that some teenagers even hurt their fingers because of the over-use of mobile phones. They keep using mobile phones for more than ten hours during a day.

Many teachers suggest that students should not have phones at school, but if there is a good reason, they can leave their phones at the school office. Many people think they understand why parents would want their children to have them, but they agree school should let the students know when they can use their mobile phones.
