fluid intelligence is the type of intelligence that has to do with short-term memory and the ability to think quickly, logically, and abstractly in order to solve new problems. it 1 in young adulthood, levels out for a period of time, and then 2 starts to slowly decline as we age. but 3 aging is inevitable, scientists are finding out that certain changes in brain function may not be.
one study found that muscle loss and the 4 of body fat around the abdomen are associated with a decline in fluid intelligence. this suggests the 5 that lifestyle factors might help prevent or 6 this type of decline.
the researchers looked at data that 7 measurements of lean muscle and abdominal fat from more than 4,000 middle-to-older-aged men and women and 8 that data to reported changes in fluid intelligence over a six-year period. they found that middle-aged people 9 higher measures of abdominal fat 10 worse on measures of fluid intelligence as the years 11 .
for women, the association may be 12 to changes in immunity that resulted from excess abdominal fat; in men, the immune
system did not appear to be 13 . it is hoped that future studies could 14 these differences and perhaps lead to different 15 for men and women.
16 , there are steps you can 17 to help reduce abdominal fat and maintain lean muscle mass as you age in order to protect both your physical and mental 18 . the two highly recommended lifestyle approaches are maintaining or increasing your 19 of aerobic exercise and following mediterranean-style 20 that is high in fiber and eliminates highly processed foods.

答案
1. 【答案】c(peaks)
【解析】逻辑关系题。and then提示顺承,借助slowly decline(慢慢下降)可知,c项peaks(达到最高点)符合原文逻辑关系,即流动智力在成年早期达到峰值,之后很长一段时间趋于稳定,之后随着年龄增长,慢慢下降。本题答案为c项。
干扰选项:a项pauses(暂停),b项returns(返回)和d项fades(逐渐消失),均不符合原文逻辑关系。

4. 【答案】b(accumulation)
【解析】逻辑关系题。and提示并列,muscle loss和the 4 of body fat around the abdomen(腹部脂肪的 4 )互相并列,借助muscle loss(肌肉流失)可知,b项accumulation(积累)符合原文逻辑关系,即,肌肉流失和腹部脂肪堆积。本题答案为b项。
干扰选项:a项detection(侦查),c项consumption(消耗)和d项separation(分离),均不符合原文逻辑关系。
5. 【答案】a(possibility)
【解析】语境题。this指代上句的研究发现,本句继续介绍研究发现。比较各选项语义,a项possibility(可能性),b项decision(决定),c项goal(目标)和d项requirement(要求),可知,a项possibility符合原文语义,即,这表明生活方式因素可能有助预防这种下降的可能性。本题答案为a项。
6. 【答案】a(delay)
【解析】逻辑关系题。or提示并列,借助prevent(预防)可知,a项delay(延期)符合原文逻辑关系,即预防或延迟流动智力下降。本题答案为a项。
干扰选项:b项ensure(保证),c项seek(寻求)和d项utilize(利用),均不符合原文逻辑关系。
7. 【答案】c(included)
【解析】语境题。本题考查连接data(数据)和measurements(测量结果)的动词词义。比较各选项语义,a项modified(修改),b项supported(支持),c项included(包括)和d项predicted(预 测),可知c项included符合原文语义,即研究人员查看了包括4,000多名中老年男性和女性瘦肌肉群和腹部脂肪测量结果的数据。本题答案为c项。
8. 【答案】b(compared)
【解析】逻辑关系题。and提示并列,looked at data和 8 that data to reported changes互相并列,借助looked at(查看)可知,b项compared(比较)符合原文逻辑关系,且能与介词to构成固定搭配,compare … to…(将……与……相比)。本题答案为b项。
干扰选项:其余各项与介词to构成固定搭配,a项devoted … to…(把……用于),c项converted … to…(把……转化为……),d项applied … to…(把……应用于……),均不符合原文逻辑关系。
9. 【答案】a(with)
【解析】固定搭配题。观察选项可知,本题考查介词用法。比较各选项,a项with(带有……),b项above(在……上面),c项by(通过……)和d项against(与……相反),可知,a项with连接higher measures of abdominal fat,作后置定语修饰people,符合原文语义,即,有着更高腹部脂肪的中年人。本题答案为a项。
10. 【答案】c(scored)
【解析】语境题。比较各选项语义,a项lived(生活),b项managed(管理),c项scored(得分)和d项played(玩耍),可知,c项scored符合原文语义,即,他们发现,有着更多腹部脂肪的中年人,在流动智力方面得分较低。本题答案为c项。

13. 【答案】c(involved)
【解析】逻辑关系题。for women与in men提示对比关系,借助the association may be 12 to changes in immunity(这种关联可能 12 免疫力变化)可知,c项involved(使成为必然部分,与be连用时,可理解为“与……有关”)符合原文语义,即,对男性来说,(这种关联)似乎与免疫系统无关;且符合原文逻辑。本题答案为c项。
干扰选项:a项restored(被恢复),b项isolated(被孤立)和d项controlled(被控制),均不符合原文逻辑关系。
14. 【答案】d(explain)
【解析】语境题。本题考查连接future studies和these differences的动词语义,而these differences是指上句中男性和女性的流动智力得分,与腹部脂肪堆积所致的免疫力变化有关与无关的区别。现有研究只发现了这种区别,而背后的原因,只能寄希望于未来相关研究。d项explain(解释)符合原文语义,即,希望未来研究能解释这些区别。本题答案为d项。
