Cellphone is very popular in our life.It is a useful tool for us to communicate with others wherever he or she is .We can also send messages to them .Apart from these,the cellphones can also be used as an alarm clock.In a word,cellphones are very useful to our life.But some people abused the cellphones .They use them to play games ,which is bad for the eyes and will waste much time .What's worse ,some people use them to send some illegal messages to others ,which can bring us much trouble.
So in my opinion ,we should make full use of the cellphone ,only in that way can we benefit from them.
