As many people hit middle age, they often start to notice that their memory and mental clarity are not what they used to be. We suddenly can’t remember【B1】______we put the keys just a moment ago, or an old acquaintance’ s name, or the name of an old band we used to love. As the brain【B2】______, we refer to these occurrences as "senior moments." 【B3】______seemingly innocent, this loss of mental focus can potentially have a(n)【B4】______impact on our professional, social, and personal【B5】______.
Neuroscientists, experts who study the nervous system, are increasingly showing that there’ s actually a lot that can be done. It【B6】______out that the brain needs exercise in much the same way our muscles do, and the right mental【B7】______can significantly improve our basic cognitive【B8】______. Thinking is essentially a【B9】______of making connections in the brain. To a certain extent, our ability to【B10】______in making the connections that drive intelligence is inherited.【B11】______, because these connections are made through effort and practice, scientists believe that intelligence can expand and fluctuate【B12】______mental effort.

选项
A、sharpness
B、stability
C、framework
D、flexibility
答案
A
解析
考查名词辨析。本句意为“…旨在帮助人们改善并恢复头脑的______”,本文强调的是大脑对事情的记忆等功能性的退变,所以应该是大脑的敏锐性,故A.sharpness“敏锐”为正确答案。B.stability“稳定性”,C.framework“框架”不符合逻辑,直接排除。D.flexibility“灵活性”有一定的干扰,可是本文没有谈到大脑是否灵活。
