Nowadays more and more teenagers are crazy about mobile phones, and most of them are used to bringing mobile phones to school. Even if there's quite much convenience which mobile phones have brought to us, we can't neglect the bad things they have at the same thime. For example, many teens' eyesight is getting worse, and some students spend so much time playing mobile phone game that they aren't able to concentrate on their study. So, I'd like to come up with some advice. Study is the most important stuff for us students, all of us are supposed to have enough moderation in playing games. Build up more other hobbies, such as fishing, skating, jogging...In this way you will find there're more interesting things in our lives than in the games.
