2009年考研英语完形填空真题解析
Research on animal intelligence always makes me wonder just how
smart humans are. 1 the fruit-fly experiments described in Carl
Zimmer's piece in the Science Times on Tuesday. Fruit flies who were taught to be smarter than the average fruit fly 2 to live shorter lives. This suggests that 3 bulbs burn longer, that there is an 4 in not being too terrifically bright.
Intelligence, it 5 , is a high-priced option. It takes more
upkeep, burns more fuel and is slow 6 the starting line because it
depends on learning-a 7 process-instead of instinct. Plenty of other
species are able to learn, and one of the things they've apparently learned is when to 8 .
Is there an adaptive value to 9 intelligence? That's the
question behind this new research. I like it. Instead of casting a wistful glance 10 at all the species we've left in the dust I.Q.-wise, it
implicitly asks what the real 11 of our own intelligence might be. This is 12 the mind of every animal I've ever met.
Research on animal intelligence also makes me wonder what
experiments animals would 13 on humans if they had the chance. Every
cat with an owner, 14 , is running a small scale study in operant conditioning. We b elieve that 15 animals ran the labs, they would test us to 16 the limits of our patience, our faithfulness, our memory for
terrain. They would try to decide what intelligence in humans is
really 17 , not merely how much of it there is. 18 , they would hope to study a 19 question: Are humans a ctually aware of the world they live in? 20 the results are inconclusive.

1.【解析】［B］语义衔接/词汇辨析题。本题目选择动词，放在祈使句句首。选项 A. suppose 认为，假定；B. consider考虑；C. observe 观察；D. imagine 想象。文章开篇指出：Research on animal intelligence always makes us wonder just how smart humans are."对动物智慧的研究总是让我对人类到底有多聪明感到好奇"，接着举了果蝇的例子，该句要选择的
动词应与上句在语义上衔接。用consider意为"让读者考虑一下(果蝇实验)"，从而引出下文，其他选项均不符合题意。
2.【解析】［A］语义衔接/固定搭配题。本题目选择动词(过去式)，与介词"to"构成动词短语，在句子中充当谓语。选项 A. tended to易于，往往会……； B. feared to 害怕做某事；C. happened to 碰巧做某事； D. threatened to 威胁要做某事。Fruit flies who were taught to be smarter than the average fruit flyto live shorter lives. 原文讲述的是在实验中经常发生的一种情况，即"通过训练变得更聪明的果蝇，其寿命往往比普通果蝇短"。故选A。
3.【解析】［D］语义衔接/词汇辨析题。本题目选择形容词比较级，在句中作定语修饰bulbs。This suggests thatbulbs burn longer, …"这让人想起……的灯泡照明时间比较长……。
"上句讲到"聪明的果蝇寿命往往较短"，这句接着用灯泡作类比，承接上句语义，应该是越
不亮的灯泡用的时间越长，所以选 D. dimmer 较暗的；选项 C. lighter更亮的，与前文意
思相悖； A. thinner 更薄的，更瘦的； B. stable 更稳定的；该两项均不符合题意。
4.【解析】［B］词汇辨析/固定搭配题。本题目选择名词，并与in搭配。选项 A. tendency 趋势，倾向，后面常接介词for或动词不定式，如： a tendency for sth.或a tendency to do sth.(做)某事的倾向； B. advantage 优势，后常接介词in，即an advantage in sth. 在某方面具有优势； C. inclination倾向，意愿，倾斜度，后常接介词for或动词不定式，
即an inclination for sth.或an inclination to do sth.想做某事； D. priority 优先权，后常接over，如：take priority over sth./sb. (比某事/某人)具有优先权。且从上
下文语义来看，前面说聪明的果蝇寿命短，越不亮的灯泡用的时间越长，所以这里语义应为"不太聪明(灯泡不太亮)是有优势的"，故B为正确选项。注意，bright在此处是一语双关，既可表示"灯泡不那么亮"，也可表示"人不那么聪明"。
5.【解析】［C］语义衔接/词汇辨析题。本题目要选择动词短语，使插入语完整。从上文
可知，"聪明的果蝇寿命往往较短"，以及"不太聪明是有优势的"，由此推出的结果是：聪明
也是要付出代价的。 C. turn out意为"结果是……"，把it turns out用作插入语，使该
句与上段内容紧紧联系起来，因此选C。A. insist on坚持；B. sum up总计，总结； D. put forward提出。这三项均不符合题意。
6.【解析】［A］语义衔接题。本题目选择介词，体现与the starting line(起跑线)的逻辑关系。选项 B. behind和C. over可以首先排除，因为这里没有涉及空间位置关系；若选
D. along则是"沿着起跑线徘徊"之意，这与后面的process意思不符；选项 A. off 有"离开"之意，slow off the starting line表示"离开起跑线慢了"，即"起步慢了"，但仍在进步，与后文逻辑一致，故选A。
7.【解析】［D］语义衔接/词汇辨析题。本题目选择形容词，做process的定语。破折号表示对前面内容即learning的解释。这里把learning(学习)与instinct(本能)作对比，结合前文的slow，以及学习自身的特点可知，只有gradual"渐进的" 符合题意。其他三项 A. incredible 难以置信的； B. spontaneous 自发的； C. inevitable 不可避免的;均不符合题意，故本题答案为D。
8.【解析】［C］语义衔接/词汇辨析题。Plenty of other species are able to learn, and one of the things they've apparently learned is when to."许多其他物种都能够学习，它们显然已经学会的一件事就是什么时候……学习。"由上文可知，聪明需要学习，很多物
种都能够学习，但都没有变聪明，这是因为它们还学会了适时停止学习。因此选C。其他三项在语义上均不通。
9.【解析】［B］语义衔接/词汇辨析题。本题目选择形容词，作定语修饰intelligence。由上文可知，智慧越多，付出的代价越多，因此智慧肯定是有限的，而且根据value也可以推断这里是关于intelligence多少的问题。选项 A.invisible 看不见的；C. indefinite 不确定的；D. different 不同的;均与数量多少无关，只有limited"有限的，不多的"符合题意，故选B。
10. 【解析】［D］语义衔接/词汇辨析题。本题目选择副词以表明逻辑关系。"we've left in the dust I.Q.wise"是定语从句，修饰the species。cast a glance at…意为"对……投以目光"；"leave sb. in the dust"是固定搭配，"将某人远远抛在后面"的意思；I.Q.
wise wise表示方式，意为"在I.Q.方面"。这句话是说"该研究不是要我们对那些在智力方面已被人类远远抛在后面的物种投以悲怜的眼光。"人类看这些被抛在
后面的物种，自然是往后看了，所以D. backward为正确选项， A. upward向上；B. forward 向前；C. afterward 之后，后来(表时间)；该三项均不符合题意。
11.【解析】［D］语义衔接/词义辨析题。本题目选择名词，做宾语从句的主语。…it implicitly asks what the realof our own intelligence might be. "这项实验含蓄地提出一个问题：人类智慧的真正……可能是什么。"前文已经提到Int elligence…is a high priced option，因此应选 D.costs。选项 A.features 特征；B.influences 影响；
C.results 结果，均不符合题意。
12.【解析】［B］固定搭配题。本题目选择介词，与mind搭配。on one's mind或on the mind of sb. 是固定短语，意为"有心事，总是想着"，其他三项均不能与mind构成固定搭配。
13.【解析】［C］固定搭配题。本题目选择动词，作为wonder引导的宾语从句的谓语。选
择的动词应与experiments搭配。选项 A. deliver 递送;D. apply 应用；两者均不能与experiments搭配。若用carry，则为carry out experiments，故只能选 C. perform 执行，perform experiments意为"做实验"。
14. 【解析】［D］词汇辨析题。本题目选择介词短语在句中做插入语，表明逻辑关系。前
文已经讲到作者很好奇，如果动物有机会的话，会对人类进行何种实验。本句接着说Every cat with an owner,, is running a small scale study in operant conditioning."
每一只有主人的猫都在进行一项有关操作性条件反射的小规模研究。"这是以cat为例进一步论述动物对人进行实验，因此应选择表示举例的介词短语，故选 D. for instance 例如。选项A. by chance 偶然；B. in contrast与……相比； C. as usual像往常一样；均不符
合题意。
15.【解析】［A］逻辑衔接题。本题目选择连词，体现句子之间的逻辑关系。由ran，would 可知，本句使用了虚拟语气，是对动物可能对人类进行实验进行了假设，故选A。选项 B. unless 除非；C. as因为；D lest 唯恐，均不符合题意。
16.【解析】［C］语义衔接/词汇辨析题。本题目选择动词，与limits搭配，作为test
的目的。选项 A. moderate 缓和；B. overcome克服；D. reach 达到。既然作为测试的目的，应为确定某些内容，故选 C. determine,这里是"查明，测定"的意思。
17.【解析】［B］语义衔接/词义辨析题。本题目选择介词，体现逻辑关系。该句承接上一
句，继续论述假设动物对人类进行实验的内容。选项 A. at表示方位; C. after表示时间；
D. with表示伴随，均不符合语义，只有 B. for表示目的，构成what…for符合语境，表
明动物们想了解人类智慧是用来干什么的。
18.【解析】［A］逻辑衔接题。本题目选择逻辑关系词，体现前后句子之间的逻辑关系。
前面两句解释了假设动物对人类进行实验会进行的的内容：它们想了解人类的某些极限，想知道人类智慧的用途。本句与前两句构成并列排比，they would hope to study aquestion"它们希望研究一个问题"，与前两句应为顺承关系，表示强调或递进，所以 B. After all
毕竟；C. However但是；D. Otherwise 否则；三者均不符合题意，只有Above all"首先，尤其是"符合题意。
19.【解析】［A］语义衔接/词汇辨析题。本题目选择形容词，作定语修饰question。选项A. fundamental基本的；B. comprehensive 综合的；C. equivalent 相等的；D. hostile 敌对的。由下文可知，这个question是Are humans actually aware of the world they live in? "人类是否真正了解他们生活的这个世界？"这应该是个最基本的问题，故选A。
20. 【解析】［C］逻辑衔接/词汇辨析题。本题目选择短语体现与前面句子的逻辑关系。
前面句子提出一个问题，本句讲the results are inconclusive(……结果是不确定的)。因此，选项C. so far"迄今为止"最符合题意， A. By accident偶然；B In time 及时；
D. Better still更好；三者都不符合语义。
参考译文
对动物智力的研究总是让我们思考人类到底有多聪明。让我们看一下卡尔·齐默
周二发表在科学时代刊物上的文章所描述的果蝇试验。有些果蝇经过训练变得比普通果蝇聪明，但是寿命却缩短了。这表明暗淡的灯泡使用时间更长，暗淡是灯泡的一个优势。
事实证明，智力是要付出昂贵的代价。它需要更多的保养、消耗更多的燃料，因
为智力依靠的是学习，这是一个循序渐进的过程，而不是一种本能，所以离开起点时进展缓慢。许多其他的物种也有学习能力，很显然他们学到的东西之一就是知道何时停止。
有限的智力是否有适应值呢？这也是此项研究的课题。我对此很感兴趣。这个试
验不是去回顾那些被我们划为低智商的物种，而是含蓄在问我们自己，智力的真正代价是什么。我们所遇到的每种动物也都在思考着个问题。
对动物智力的研究也让我想，如果动物有机会的话，他们会对人类作什么样的实
验。比如说，每只有主人的猫都在进行一个小型的操作性条件反射研究。我们认为如果动物也能进行试验的话，他们会测定我们的忍耐度，忠诚度，以及对地形的记忆力。他们会试图判定人类智力的实际用处，而不仅仅是判定人类智力的高低。最重要的是他们希望研究一个最基本的问题：人类是否真正意识到了自己所生存的世界？对此，目前仍无定论。
The human nose is an underrated tool.Humans are often thought to be insensitive smellers compared with animals,1 this is largely because,2 animals,we stand upright.This means that our noses are 3 to perceiving those smells which float through the air,4 the majority of smells which stick to surfaces.In fact5,we are extremely sensitive to smells,6 we do not generally realize it.Our noses are capable of 7 human smells even when these are 8 to far below one part in one million. Strangely,some people find that they can smell one type of flower but not another,9 others are sensitive to the smells of both flowers.This may be because some people do not have the genes necessary to generate 10 smell receptors in the nose.These receptors are the cells which sense smells and send 11 to the brain.However,it has been found that even people insensitive to a certain smell 12 can suddenly become sensitive to it when 13 to it often enough.

2015年考研英语（一）深度解析：完型 1. [A] what 【解析】此题考查疑问代词辨析：题干中过去分词短语published from the University of California and Yale University…作后置定语，修饰study，而真正的句子主干是That is 1 a study has 2 .简化后的句子可以让我们清晰地看出第一题要说的是研究study的具体内容是what，不是方式how，也不是原因why，更不是时间when。 2. [B] concluded 【解析】此题考查动词辨析：同第一题一样，根据简化的句子That is what a study has 2 来解题。题目选择的动词是说明study怎样才有了上面what表示的内容。所以此题选择concluded“推断;得出结论”。其他的动词据不符合要求。 3. [D] on 【解析】此题考查介词辨析：根据题干The study is a genome-wide analysis conducted 3 1932 unique subjects的要求，所选择的介词能用在conduct“实施;进行”之后，又得和subject 搭配，所以这个题目应该选择on，构成on some subjects“关于某类主题”。 4. [C] compared 【解析】此题考查动词辨析：通过观察题干，我们发现第4题位于which引导的定语从句之内，作从句的谓语动词。Which修饰主句的主语study“研究”，如此补全定语从句就是： The study 4 pairs of unrelated friends and unrelated strangers…所以正确答案选择C。该项研究是对比所选择的两个样本。其他选项都不符合题意。 5. [C] samples 【解析】此题考查名词辨析：The same people were used in both 5 .通过观察题干，我们发现第5题空前的单词是both，表示“两者都…”。而上文中提到两者的只有“unrelated friends”和“unrelated strangers”，即这项研究的两个样本，所以答案选择C. samples“样本”。 6.[A] insignificant 【解析】此题考查形容词辨析和让步关系：题干While 1% may seem 6 , it is not so to a geneticist句首的While引导让步状语从句，同时提示我们逗号后和逗号前的内容形成一定程度上的对立关系，而且作者的表达重点位于逗号之后，1%的数量对于基因研究者来说影响程度很大。那么对于普通人而言这个数据就显得微不足道了。正确答案只能选择A。 7. [C] know 【解析】此题考查动词辨析和转折关系：题干Most people do not even 7 their fourth cousins but somehow manage to select as friends the people who 8 our kin中说“大多数人甚至不他们的第四代表亲，但是尽量选择和亲属人作为朋友”。even“甚至”这一个词就提示我们应该本题只能选择know“了解，认识”，其他选项都不符合题目要求。 8.

历年考研英语完形填空真题（2005） The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, 1 this is largely because, 2 animals ,we stand upright. This means that our noses are 3 to perceiving those smells which float through the air, 4 the majority of smells which stick to surfaces. In fact 5 , we are extremely sensitive to smells, 6 we do not generally realize it. Our noses are capable of 7 human smells even when these are 8 to far below one part in one million. Strangely, some people find that they can smell one type of flower but not another, 9 others are sensitive to the smells of both flowers.
