【题目】 No matter where a video game is played, on a handheld device(装置), the Internet or the television, too much gaming is a bad thing. Playing too many video games is a problem for kids and there are many signs that show the negative(消极的) influences.

If young people are always thinking about when they can play a video game, that is a sign that they have lost themselves in it. If they give up other hobbies that they used to love, that is also a problem. Many kids who choose to spend all their free time playing video games will make up ways to play the game instead of communicating with others. Leaving sports teams or clubs, refusing to go outside to play with friends, and choosing to stay home from birthday parties are all signs that video games have taken over the child’s attention.

In addition to negative behaviours, there are health problems from playing too many video games. If video game players skip meals or lose sleep because they stayed up too late playing games, this can negatively influence their health. Sitting in front of a game for more than two hours a day instead of getting up and being active can result in childhood obesity(肥胖症). Moreover, backaches, headaches and strained(紧张的) eyes can be caused by playing too many video games.
