问题     Parents who believe that playing video games is less harmful to their kids’ attention spans than watching TV may want to reconsider. Some researchers【C1】______more than 1, 300 children in different grades for a year. They asked both the kids and their parents to estimate how many hours per week the kids spent watching TV and playing video games’ and they【C2】______the children’s attention spans by【C3】______their schoolteachers. 【C4】______studies have examined the effect of TV or video games on attention problems, but not both. By looking at video-game use【C5】______TV watching, these scientists were able to show for the first time that the two activities have a similar relationship【C6】______attention problems.
    Shawn Green, a psychologist at the University of Minnesota, points out that the study doesn’t distinguish between the type of【C7】______required to excel at a video game and that required to excel in school. "A child who is capable of playing a video game for hours【C8】______obviously does not have a【C9】______problem with paying attention," says Green. "【C10】______are they able to pay attention to a game but not in school? What expectancies have the games set up that aren’t being delivered in a school【C11】______?" Modern TV shows are so exciting and fast paced that they make reading and schoolwork seem【C12】______by comparison, and the same may be true【C13】______video games, the study notes.
    "We weren’t able to break the games down by educational versus non-educational【C14】______nonviolent versus violent," says Swing, 【C15】______that the impact that different types of games may have on attention is a ripe area for future research. [br] 【C8】
