Nowadays with the development of Internet, nobody can avoide making a fully use of it in daily life and work. Mostly, middle school students spend much time on video games, chatting, listening to their favourite songs, seeing movies and so on, even they depend on the Internet to solve problems in their lessons.

We have to admit that the Internet is somehow helpful in a studen"s study. But it"s worth thinking about whether we should allow a middle school student to take a mobile phone with him during school hours. Only because of their self-controlling power, it is easy for him to be addicted to the world in the Internet while he should concentrate himself in his lessons. Anyway, the bad influence of Internet in a student"s school life cannot be ignored.
