2013年12月英语四级作文真题附范文(第2套):手机

With the development of science and technology,mobile telephone becomes more and more popular.Even the students on campus begin to use mobile telephone.Is it a good or bad thing? On the one hand,is good to the students. For one thing,it enables them to keep in touch with their friends and family more conveniently and quickly. For another, learn about the world through the internet. On the other hand,mobile telephone has a negative effect on the students. First, it will cost them more money than before.Second,it will distract them from their study. In my opinion，the main purpose of students at the university is to learn, and we should value our learning. Try not to spend too much unnecessary time on your phone.
