Computer game problems
Good afternoon, parents and teachers. Thank you
for attending this meeting.
Last weekend, one of our students went to hospital. The student played computer games on the Internet all day Saturday without stopping to drink, eat or sleep. Finally, he became very ill.
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.
Greetings

2 Use more specific words to get better results.
Example: You may improve your search for the comparative of adjectives by adding a specific word:
In this way, you will get more specific and useful results.
exactly the same words and in the same order
3 Use double quotation marks (“…”)to find web pages containing specific groups of words or phrases.
Example: You may type in comparative of adjectives in double quotation marks:
