Good afternoon, parents and teachers. Thank you for attending this meeting.
Last weekend, one of our students went

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.
