     Games are fun. After hours of homework it's great to relax by playing a game. But do games ever do

kids any harm (害处)? And are there any ways parents can help kids stay away from bad games? The US

researchers are trying to find solutions to these problems.

     They studied what video games could do to children. The researchers found game sellers had made big

changes to make sure the games didn't harm kids. And they suggested that work should be done to find out

if video games affected children's school work and health.

     One problem found was that parents hadn't taken enough notice of their kids' game-playing habits.

     "Many game sellers put control (控制键) on the games to help parents make sure that children don't play

games unsuitable for them," said David Walsh, the president (院长) of the National Institute on Media and

the Family. Parents should watch the games kids are playing and know how much time they are spending

playing them.

     The study found that playing games too long could affect kids' health as well as their school work. Almost

half of all "heavy garners" were six to seventeen years old. These kids were more likely to have weight and

eyesight problems than other kids. Playing too many games also affected how children did at school.

     Kids are supposed to ask their parents to set a time limit (限制) for playing games and remind them

when the time is up.
