15、Harmful influence of cyber centers

The internet has brought people great convenience in getting information, entertainment and contact with others, and it has also benefited some businessmen, especially the owner of cyber centers. While it is true that most cyber centers are run legally, it is also true that some are offering unhealthy programs that involve violence and sex content. Since most middle school students are easily influenced and they can hardly tell which cyber centers are good and which ones are not, it is only advisable that they stay away from all. Besides, staying away from cyber centers also does good to students’ physical health. By passively sitting too long in front of the computer screen, both their eyesight and bodies suffer.
