1、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 Zimmers 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

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

9、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
10、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。T
11、his 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
12、.(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，br
13、ight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
14、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
15、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 theyve 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。
