More and more people have mobile phones in China. Mobile phones offer us a lot of convenience. We can
call each other at any time. And also we use them to send short messages. However, mobile phones bring us
some trouble. We have to pay for a wrong number, and using them too much is bad for our health. As a
student, I think we can have mobile phones, because our parents can easily know what happens to us. But,
I don't think it right to keep mobile phones on in class, and we shouldn't spend too much time to send
messages to others because it needs too much time and money.
