Nowadays,with the development of technology.more and more students go to school with cell phones,which has many advantages and also disadvantages .
First,Cellphones give us much convenience to keep in touch with our family and friends.Then,it brings much fun to us ,making our life colorful.
On the other hand,it can make us turn our attention to other things ,causing us not to concentrate on our study.Besides,it will cost us much money for the phone bills.
In my opinion,each coin has two sides.Only when we make best use of it can we benefit from it .
