问题     Video game players may get an unexpected benefit from blowing away bad guys — better vision. Playing "action" video games improves a visual ability【C1】______tasks like reading and driving at night, a new study says.
    The ability, called contrast sensitivity function, allows people to discern even subtle changes【C2】______gray against a uniformly colored backdrop. It’s also one of the first visual aptitudes to fade with age.
    That’s【C3】______a regular regimen of action video game training can provide long-lasting visual power, according to work led by Daphne Bavelier of the University of Rochester.
    Previous research shows that gaming improves other visual skills, such as the ability to track several objects at the same time and【C4】______attention to a series of fast-moving events, Bavelier said.
    "A lot of different aspects of the visual system are being enhanced,【C5】______one," she said. The new work suggests that playing video games could someday become part of vision-correction treatments, which currently rely mainly on surgery or corrective lenses.
    "【C6】______you’ve had eye surgery or get corrective lenses, exposing yourself to these games should help the optical system to recover faster and better, you need to retrain the brain to make use of the better, crisper information that’s coming in【C7】______a result of your improved eyesight," Bavelier said.
    Expert action gamers in the study played first-person shooters Unreal Tournament 2004 and Call of Duty 2. A group of experienced nonaction gamers played The Sims 2, a "life simulation" video game. The players of nonaction video games didn’t see the same vision【C8】______, the study says.
    Bavelier and others are now trying to figure out exactly why action games【C9】______seem to sharpen visual skill. It may be that locating enemies and aiming accurately is a strenuous, strength-building workout for the eyes, she said.
    Another possible【C10】______is that the unpredictable, fast-changing environment of the typical action game requires players to constantly monitor entire landscapes and analyze optical data quickly. Finally, Bavelier said, the games’ rich payoff may also play a role.
    "It’s pleasing to be successful in your mission," she said. "When you combine rewards with these other "factors", then you get much more learning."
【C1】
选项 A、ascribe to
B、key for
C、inclined to
D、crucial for
答案D
解析 本题考查形容词充当后置定语。原文的主题句为首段第一句：游戏玩家可能会因为打跑坏蛋得到意料之外的好处——视力变得更好。空格前说到玩动作游戏需要一种视觉能力，这种能力对阅读或者夜间驾驶是非常重要的。因此本题选D(至关重要的)，key也表示“重要的，关键的”，但常跟的介词搭配为to。因此本题正确答案为D。
