Reading Comprehension
从下列每篇短文的问题后所给的四个选择项中选出一个最佳答案。

     Today's video game worlds in the U.S.A. are so detailed that they give the player a realistic and rewarding experience. It is not just children that play these games; it is also common for men from 18 to 30 have at home some sort of game console（控制器）.
     People think this may affect real-life behavior and ask ‘are life-like computer games a good thing?’, especially the first-person games where the player takes on active roles like shooting at others in armed battles.
     As modern characters in computer games have become more people-like than cartoon-like, as the language becomes more informal or casual, and as the sound effects become more realistic, many kinds of concern have been raised about the link between computer games and the children's aggressive behavior. Worried parents have welcomed the computer game classification, which is similar to film ratings. This makes it easier for parents to monitor what their children are playing with.
     Are computer games making us more aggressive? There is no evidence that proves a link between an increase in computer game violence and aggressive or violent behavior in children, but the question still arises: is it acceptable for computer games to depict life-like scenes of violence?
     What lessons do players take from games like Grand Theft Auto where players speed through city streets trying to reach their destination in the quickest time regardless of people walking along the streets in their way or Hooligans: Storms over Europe where men run violently into football fields, fight competitors and attack police. Do you think these computer games make it difficult to tell right from wrong and fact from fiction?
