     With the development of science and technology，more and more children are attracted to play

computer games which they're keen on for almost day and night. It does great harm to children's health,

especially to their eyes. For the sake of children's health, parents and teachers should help them to play

more traditional and healthy games. After all, children's health comes first.

     However, what kinds of measures should we take？First，we should let them know the benefits of

the traditional and healthy games. Then we should limit their time and places of playing computer games.

Finally,train children's abilities of judging the games' advantages and disadvantages, because parents and

teachers couldn't accompany them forever. Only children themselves can keep a healthy life through their

own efforts to play the traditional and healthy games.
