Cell phones have become increasingly popular in china these days. 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. |
