Want an “OK” from your parents when you start to miss your favorite on-line game? It’s    小题1: but possible now.
Last week, the China Youth Internet Association said it would find more games for teens. It has made standards (标准) for computer games for  小题2: kinds of age groups. These standards are the first in China.
“We hope the standards can tell students   小题3:  games they can play,” said Shao Dehai, head of the association. “Students can keep away from bad games.”
Which games are OK? Many people made the standards. They were  小题4:  for grown-ups. It’s better for makers to use stories from history and geography in their games. This makes  小题5:  more fun.
Junior games have rules for players as well. If you use bad words too many times, you may be   小题6:  from playing the game.
You can’t spend too much time on games. The computer will stop the game when your time is up. Great, right? Your mum may even be   小题7:  than you.
These standards aren’t ready yet. The association is asking for ideas  小题8: all game-lovers. Want to know more about the standards? Go to www.game315.com/yxfj. At this website you can also tell  小题9:  how you feel about some games. If you have some good ideas for the standards, you can write to: game@swm.com.cn.
