Many experts are so【C6】______of the benefits of challenging the brain【C7】______they are putting the theory to【C8】______in their own lives. "The idea is not【C9】______to learn to memorize enormous amounts of information," says James Fozard, associate director of an institute【C10】______aging. "Most of us don’t need that kind of skill.

选项
A、maintain
B、sustain
C、retain
D、obtain
答案
A
解析
语义衔接题。[A]maintain、[B]sustain、[C]retain都有“保持”的意思,但侧重点不同。maintain常用来指维持已有的水平、标准;sustain常用来指支持、维持生命;retain常用来指保留某物。[D]obtain“获得”。结合语境,此处是说保持头脑的机敏,备选项中只有[A]符合语境,故答案为[A]。下文提到的maintain their intellectual abilities对本题有提示作用。
