问题     Many parents are【S1】______about the fact that their children play many video and computer games. Perhaps the best way to【S2】______concerns over the【S3】______of video games is to emphasize their vast【S4】______to educate. Even games with no educational【S5】______require players to learn a great deal. Games are complex, adaptive and force players to make a huge number of decisions. Garners must learn rules through trials and errors, solve problems and puzzles, develop strategies and get help from other players via the Internet when they get stuck. The problem-solving【S6】______that underlies most games is like the 90% of an ice berg below the waterline-invisible to nom-gamers. It is the pleasure of this problem solving, not the violence which sometimes【S7】______it, that can make gaming such a【S8】______experience. Nobody is using certain violent games in schools, of course, but other off-the shelf games such as "Sim City", which【S9】______model economies, are used in education. By playing them it is possible to understand how such models work. In "Sim City", for example, in which the player【S10】______the role of a city mayor, no amount of spending on health care is ever enough to satisfy patients, and the fastest route to popularity is to cut taxes.
