Many years ago, cellphone was not allowed to used for high school students. Teachers would take away students’ cellphone once they saw it. But now the phone has been part of people’s life and almost every student uses it. It is just the popular communication tool. For many high school students, they are easy to be addicted to keeping chatting with their friends and not pay attention to the class. For me, I have controlled myself not to play it in the class, so I will turn off the phone and not to think about it. Some parents believe that using cellphone is not good for students, the fact is that students can learn a lot from the cellphone, they can search the Internet for more information, so as to get better solutions.
