  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 believe 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 actually aware of the world they live in? 20  the results are inconclusive。

  文章背景

  本文是一篇讲述动物智能、偏重科技的文章。此文章最先刊登在2008年5月7日的《纽约时报》上,原文的标题是 The Cost of Smarts,翻译过来是“聪明的代价”。文中通过对“果蝇”的试验研究得出“聪明是要付出代价”的结论,最后提出引人深思的问题——人类是否真正意识到自己所生存的世界。

  文章结构

  本文采用了对比的方式展开文章,叙述了人类智慧发展的代价。第一二三段围绕人类对动物智能的研究对动物以及人类自己造成的影响。文章的最后一段作者展开丰富的联想,如果动物对人类做实验的话,它们想从人类身上获取什么信息呢?

  答案详解

  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是派生词,后缀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。
