【参考答案】

1.【答案】Cpeaks

【解析】此处考察词义辨析+句间逻辑关系。文章首段首句为主题句，谈到一个概念∶流体智力(fuid inteligence)，是一种智力类型，它与短期记忆和快速、逻辑和抽象地思考以解决新问题的能力有关。想要解决空格处需要分析整句话的逻辑关系。前文提到青年人，后文提到这种流体智力智力随着年龄增长会慢慢下降，所以根据时间发展的关系，前面提到这种智力在青年时达到峰值(peaks)，并且会停留一段时间，随后随着年龄的增长会逐渐下降。正确答案为peaks。pauses 暂停; retum 恢复，返回; fades 逐渐消退。

2.【答案】D generally

【解析】此处考察词汇辨析。根据上一道题目的具体分析，不难得出空格处应该是对这种普遍现象得修饰，weage 体现我们大所数人，所以应该选择Dgenerally。altematively 要不然，或者(二者择其一); formally 正式地，正规地;accidentally 偶然地。

3. 【答案】A while

【解析】此处考察句内逻辑关系。空格处所在句子是以转折词 But 开始，但考察句内之间

的意思转折∶但是，_3__年纪增长不可避免，科学家发现某些大脑功能不会发生变化。年纪增长和科学家的发现是对立的观点，所以应该选择while，尽管。since 因为;当…...时;once

一旦; until 直到。

4. 【答案】C consumption

【解析】此处考察词义辨析+句内逻辑关系。并列连词 and将空格处与前文muscle loss 并列，行车前后近义词的关系，那么空格处要选择一个与肌肉消失表达意思相近的词。所给选项中只有C选项consumption 意思是消耗的意思，带入原文符合句意。detection 侦查，勘察; accumulation 积累，积攒，增加;separation 分开，分离。

5. 【答案】A possbility

【解析】此处考察词义辨析。suggest 一词是解题的关键，这个单词用在考研英语的文章中大部分都是暗示的意思，that 引导的同位语从句中句子的谓语动词前还有情态动词 may 表推测，这都是在说明一种不太确定的可能性，所以选择 possbility。decision 决定;goal 目标; requirement 要求。

6.【答案】A delay

【解析】此处考察词义辨析+句内逻辑关系。并列连词 or将空格处和前文 prevent 构成近义词的关系，delay 延迟和prevent 阻止是相近句意表达。ensure确保;seek 寻求，请求;utilize利用，使用;

7. 【答案】C included

【解析】此处考察词义辨析。根据题干和选项特点不难看出句中 that 引导的是一个定语从句，从句列举了data 的具体分类和实验人群，所以定语从句是在具体说明 data 的内容，要选择

included包含，包括。modified 改变;supported 支持; predicted 预测。

8. 【答案】B compared

【解析】此处考察动词短语词义搭配和辨析+上下文语境。空格处表devote to 把……专用于，完全用于;compareAto B 将A和B进行比较; convertAtoB 将A转变成B;applyAtoB将 A应用于B。空格处所在句意为将那些数据和已知报道进行…。后文和下文都是在进行不同情况的比较来得出答案，所以应该选择 compare。

9.【答案】A with

【解析】此处考察介词的用法。这个介词里只有with 能体现的是某种状态∶有着较高腹部脂肪检测结果的中年人…….

10.【答案】C scored

【解析】此处考察词义辨析+上下文语境。空格处所在句子表达∶有着较高腹部脂肪单位的中年人在流体智力检测时得分不高，测量智力是会得出具体分数的，就像我们平时说的智力测试。lived 生存，活着;managed 完成;scored 得分; played 表现。

11.【答案】D went by

【解析】此处考察动词短语辨析。…as the years went by.随着时间的流逝，也算是固定的搭配。ran out 耗尽，放弃;set off 出发，动身，启程;drew in 吸引，拉入。

12.【答案】B attributable

【解析】此处考察形容词辨析+上下文逻辑关系。空格处所在句子用分号隔开，分号代表前后两句话讨论得是一个问题，有可能相同也有可能相反。分号前说免疫系统对于女性来说的作用，后文是用男性来进行比较，说免疫系统对于男性的变化没什么作用。前后是相反的观点，所以免疫系统对女性是有影响的。attributable to 归因于…;superior to 优于，胜于; parallelto 平行于，与……平等;resistance to 抵抗。

13.【答案】C involved

【解析】此处考察非谓语动词词义辨析。分析了上一题，这一道题也迎刃而解，空格处所在句子是在表达对于男性而言，免疫系统没有对其产生影响，didnot appear to be involved，似

乎不涉及在内。

14.【答案】Dexplain

【解析】此处考察动词辨析+句意理解。Itis hopedthat …体现出是寄希望于以后的实验研究来得出结论。alter 改变，变更，更改;spread 开展，传播;remove 移除，清除。

15.【答案】D treatment

【解析】此处考察词义辨析。空格处所在句子表明∶ 希望今后的研究能够解释这些差异，并可能导致对男人和女人的不同待遇。因为有差别才应该采取不同的对待方式。compensations补偿;symptoms 症状;demands 要求，需求; treatments 处理，对待。

16.【答案】B Meanwhile

【解析】此处考察段落之间的逻辑关系。there are steps 体现出有一些措施可供参考，可见空格处所在段落体现本段与上一段之间的递进的关系。meanwhile 同时;Likewise 同样地，也; Therefore 因此; Instead 代替，而不是。

17.【答案】D take

【解析】此处考察定语从句+短语搭配。 there are steps you can 17 to help reduce abdominalfat…youcan 的前面省略了定语从句关系词that，从句修饰 steps，take steps to do短语表示采取措施做某事。Change 改变; watch 注意，观察; count 数数。

18.【答案】A well-being

【解析】此处考察固定短语搭配。physical and mental well-being 身心健康。

19.【答案】A level

【解析】此处考察词义辨析+句意理解。空格所在处意思是给大家推荐两种生活方式，一是保持或提高你的有氧运动水平。Love 喜爱; knowledge 知识;space 空间。

20.【答案】C diet

【解析】此处考察单词辨析+定语从句。空格处后面that 引导的从句是这道题的解题关键∶ that 引导定语从句，对前面的名词进行修饰，那么从句的内容就是先行词得以选出得重要线索。从句中主要讨论事物的问题，那么空格处应该填入diet饮食符合语法结构和句意表达。 Design 设计; routine 行程，流程;prescription 处方。
