Some students play computer games for too long. This is a serious problem. In the past, students used to play outside more often, but now they spend more time in front of computers. This is bad for their health.
Tomorrow we’ll have some experts here to talk to the students about the bad effects of playing computer games. They’ll also give some advice on how to use computers for studying.
I hope we can all work together to stop students from spending too much time playing computer games. Thank you for your time.

Advantages and disadvantages
of the Internet
The Internet has come into students’ life. It brings us not only a lot of convenience and happiness but also troubles. 21世纪教育网版权所有
Some students use the Internet as a tool to study. When they learn English, the Internet helps them a lot. They also read news, send and receive emails through it. 21教育网
However, some students are addicted to chatting and playing games. It is harmful to students to watch bad films. Sitting in front of computers too long is also bad for students’ eyesight.
It is clear that the Internet has advantages and disadvantages. I think we should use it correctly.21·cn·jy·com
