According to a report from the Entertainment Software Association （ESA）， the sale of video games in the United States has more than doubled in the past 10 years， from $2.6 billion in sales in 1996 to $7 billion in 2005. Analysts say that these numbers are very alarming， and many people are asking， "Can gaming become an addiction？" Elizabeth Woolley said， "Computer games， like any other activity， can be hard to stop once an addiction has been formed."??? Many students are addicted to computer games and they even neglect eating and bathing. They don't go to school，playing games for hours or days. It is said that last year，seven people in South Korea died as a result of too much gaming. "??? We have kids who don't know how to communicate with people face to face because they've spent three years playing games and talking to others through a computer，" said a father.
