Cell phones have become more and more popular in china recently.wherever you go you can see people using cell phones.Many college students,even high school students have cell phones.
Cell phones have brought people a lot of benefits,but the most important is that they are convenient.with cell phones in their hands,they can keep in touch with anybody they want.if they want to get some information from the internet,they can easily have their dream realized via cell phones too.furthermore,if someone has a heart attack or a traffic accident,a call to emergency hospital or to the police can quickly bring him the help he wants.
However,cell phones can also bring people problems.the most serious is the electric wave radiation which is thought to be harmful to users' brains.another problem is that when people are having a meeting or having a class or at a concert etc,the ring of the cell phone may interrupt others.so i think children should use cellphones as little as possible and turn them off when they are attending important meetings or attending classes.

All in all,it is a useful tool.It makes our world far smaller than ever and shorten the distance between people.
On the other hand,there are some drawbacks,too.
overuse of cell phone do harm to people's health,it has negative effects on people's eyes,and many people know that the radiation emitted by cell phones cause brain tumor.If you talk for so many hours,you are going to have headache and ear problems.some people heavily dependent on cell phones will lost their face-to-face interpersonal skill,they can chat to several people at the same time through their cellphone but they can't perform well in a face-to-face meeting.Some students abused the cell phones.They use them to play games ,which is bad for the eyes and will waste much time.It is obvious that carrying can disturb teaching in class and it can cause the comparison between students.So the attitude towards mobile should be forbidding using mobile in school
