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.

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。
2. 【答案】D(generally)
【解析】语境题。比较各选项语义,A项

3. 【答案】A(while)
【解析】逻辑关系题。观察选项可知,本题考查句内逻辑关系,比较aging is inevitable和scientists are finding out that … may not be可知,inevitable和may not be提示语义相反,即“衰老不可避免”,与“科学家们发现大脑功能的某些变化可能并非不可避免”二者语义相反。A项while(尽管)提示让步,符合原文逻辑关系。本题答案为A项。
干扰选项:B项since(由于)提示因果关系,C项once(一旦)提示条件关系,D项until(到……为止)提示顺承关系,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。

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。
