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 people should use cellphones as
little as possible and turn them off when they are attending important
meetings or attending classes.
