With the development of the Internet, the net bar plays an important role in people s life. More and more people, especially students, like to go to net bars.They are absorbed in playing video games, making bad friends and having a chat with Meimei on the net in the bar. Some students often go on playing late into the night in the net bar. As a result, not only does it do harm to their health but also produces a bad effect on their studies.

　　Now a lot of net bars have been shut down in Beijing. But some students go by bus to the net bars at suburbs to play. Fortunately, more and more parents and schools have realized it. Recently, more than six thousand students guaranteed that they would be far away from net bars in Jinzhou city, Liaoning Province. It is quite necessary for the students to get rid of the bad habit.
