As we know, with the development of society, more and more students are having cellphone. They are given as presents from parents, friends or relatives. In my opinion, the disadvantages are much more obvious than advantages of using cellphone. Here are my reasons.
First, cellphone will distract us from listening to the teachers in class. For example, while we are having class, and the cellphone rings, no doubt, it will distrub all of us, including teachers and students. So it will have an negative effect on our study.
Second, it is clear to us that using cellphone will do harm to our health and brain, according to the scientific survey. From the point of health,let's stop using the cellphone.
Last but not the least, many of us use cellphone to communicate with our friend. But the question is whether they are all good to you. It may easily lead to us have bad friends.本回答被网友采纳
