15、着头，从猎物的身上撕下大块大块的肉，把它们吞了下去。很快地，猎食活动就结束了。为了生存而移动鲨鱼追逐猎物的过程以一种夸张的方式证明了移动或者运动对于动物的重要作用。像鲨鱼一样，大局部的动物通过移动来发现食物。他们还利用移动来逃避敌人、寻找配偶、开拓新的地盘。移动的方法包括：爬行、跳跃、滑行、飞行、飘浮或者漫步。借助各种有助移动的创造，人类加强了其移动优势，可以在任何环境下移动。汽车、火箭、潜艇能把人类从深海运输到遥远的月亮。然而，对于其他的动物而言，移动来源于数百万年的进化。鲨鱼是其中最成功的例子。它能够以接近零的时间快速地捕获猎物，这给科学家们留下了深刻的印象。但是，经过仔细地研究，美国杜克

16、大学的海洋生物学家S. A. Wainwright、F. Vosburgh和J. H. Hebrank才发现了鲨鱼是如何做到这一点的。在研究中，科学家们对位于佛罗里达州圣奥古斯丁海上乐园泳池中游泳的鲨鱼进行了观察。他们拍摄了鲨鱼的运动情况，对它们进行了分析，同时也对鲨鱼的皮肤和肌肉进行了研究。皮肤是关键生物学家们发现，鲨鱼的皮肤是它们在水中高效游动的关键。鲨鱼的皮肤中含有许多纤维，像子午线轮胎的内部一样交错在一起。这些纤维被称为胶原纤维。随着它们的放松或拉紧，这些纤维可以储存或释放大量的能量。当拉伸纤维时，纤维中蓄满了能量，就像绷紧的弓弦一样。能量被释放后，纤维就松弛了。杜克大学的生物学家发现

17、，最大拉伸发生在鲨鱼弯曲身体游动的时候。当身体前后移动时，弯曲处外侧的纤维受到强烈的拉伸，大量的潜能被储存在纤维中。当鲨鱼朝另一个方向迅速掉头时，这种能量就被释放出来了。随着能量在鲨鱼身体两侧交替地储存和释放，它的尾巴就像鞭子一样强烈地来回摆动。这种像皮鞭一样的动作促使鲨鱼像发射的子弹一样在水中穿来穿去。能量的来源是什么让纤维能存储如此多的能量呢?在追寻答案的过程中，杜克大学的科学家们发现，鲨鱼与子午线轮胎的相似性并不仅仅存在于皮肤上。正如子午线轮胎是由压力膨胀的一样，在鲨鱼胶原辐射处的下方也有一个膨胀区。但是，鲨鱼体内的压力可能来自于血液压缩胶原纤维而产生的压力，而不是来自于空气的压力。当鲨

18、鱼缓慢游动时，纤维内的压力相对较低。纤维比拟松弛时，鲨鱼就能以锐角的角度弯身。在寻找食物或只是游动时，鲨鱼以这种方式进行移动。但是，当它发现重要的食物来源时，一些奇妙的变化就自动发生了。鲨鱼内部的压力可能会增加10倍，胶原纤维在这种压力下剧烈拉伸，蓄积了大量的能量。接着，这种能量被转移到尾巴上，鲨鱼快速运动起来，剩下的事情就可想而知了。海豚是速度最快的纪录保持者海豚是另一种快速的海洋动物，这种海洋哺乳动物的速度为每小时20英里。研究海豚的生物学家们发现，就像鲨鱼一样，海豚的快速游动可以追溯到其皮肤。海豚的皮肤是这样构成的：它对流过其身体的水流产生的阻力很小。通常情况下，当鱼或其他动物在水中缓慢

19、游动时，水流会平稳地流过它们的身体。这种平稳的水流被称为层流。然而，当鱼快速移动时，其周围的水流就变得湍急起来。这种乱流使摩擦加大，降低了鱼的速度。海豚的皮肤弹性很大，可以随着水波的波形而弯曲。实际上，水波是被卷进了海豚皮肤的皱褶处。这样，其余的水就以层流的方式从其身边平稳地流过。其他动物快速游动时，由于受到乱流的阻碍，其速度就降低了；但是，海豚却能够以破纪录的速度在水中快速穿行。其他的低速动物并不是所有的动物都能像鲨鱼和海豚一样快速地游动。在运动效率方面最大的输家可能是蛞蝓鼻涕虫。它看起来就像没有壳的蜗牛，其爬行过的地方会留下一条细细的踪迹。它要使用大量的能量制造黏滑的黏液，以便在其上爬行。

20、移动同样的距离，老鼠只需要其所消耗能量的十二分之一。科学家们认为，由于蛞蝓鼻涕虫利用能量的效率很低，所以它的生活必然受到一定的限制。换句话说，它们都被迫把自己束缚在很小的区域之中来搜寻食物和寻找适宜的生活条件。人类曾经面临过这样的问题吗?1.【答案】D)【解析】属同义转换题，此题是一种排除选择题。根据题干中的中心词“movement to do something，可以将答案定位在小标题“Moving to Survive下第二段的前两句话，“Like the shark, most animals use movement to find food. They also use locomo

21、tion to escape enemies, find a mate, and explore now territories。该句与题干是一种同义转换，选项A)、B)和C)在原文中均有提及，所以不是正确选项；答案D)在原文没有提及，所以是正确答案。2.【答案】B)【解析】属细节推断题。题干考查汽车、火箭和潜艇的例子是为了说明什么，其中的“examples of automobiles, rockets and submarines是关键词，可以将答案定位在文章小标题“Moving to Survive下第三段的前两句话，“Humans have the added advantage of

22、 using their various inventions to move about in just about any kind of environment. Automobiles, rockets, and submarines transport humans from deep oceans to as far away as the moon，第二句话所举例子正是为了说明第一句话的内容，这与B)项意思一致，而其他选项在文中均未提及。3.【答案】A)【解析】属细节推断题。分析题干，此题考查鲨鱼在水中快速游动的关键是什么。其中的“key是关键词，可以将答案定位在小标题“Skin

23、 Is the Key下首段的第一句话，“The biologists discovered that the skin of the shark is the key to the animals high efficiency in swimming through the water，这与选项A)完全一致，所以直接选择A)即可。其他选项在文中均有提及，但是都不符合题干的要求。4.【答案】D)【解析】属细节推断题。题干中的“the Duke University scientists是关键词，可以将答案定位在小标题“Skin Is the Key下第二段的第一句话，“The Duke Un

24、iversity biologists have found that the greatest stretching occurs where the shark bends its body while swimming。这与选项D)的内容完全一致，所以答案选D)项，而其他选项原文均未提及，为干扰项。5.【答案】C)【解析】属细节推断题。题干中“a belted radial tire是关键词，可以将答案锁定在文章小标题“Source of Energy下第一段的第三句话，“Just as a radial tire is inflated by pressure, so, too, is

25、 the area just under the sharks collagen radials。其中的“just as和“so正说明了两者的相似之处在于“inflated by pressure，所以答案应该是C)。选项A)和B)是两者的不同之处，选项D)在文中没有提及。6.【答案】A)【解析】属细节推断题。题干中的关键词是“a laminar flow，所以可以将答案锁定在文章小标题“Dolphin Has Speed Record下，根据该节第一段的倒数第三、四句话，“Normally when a fish or other object moves slowly through th

26、e water, the water flows smoothly past the body. This smooth flow is known as laminar flow.。题干是对这两句话的改写，所以正确答案是A)选项。其他三个选项的意思均不符合“a laminar flow的定义，与题干要求不符。7.【答案】C) HYPERLINK / 考试就到考试大【解析】属同义转换题。题干中“a slug和“a mouse均为关键词，可以直接定位在小标题“Other Animals Less Efficient下第一段的第二句话，“It uses so much energy . a mou

27、se traveling the same distance uses only one twelfth as much energy。题干是对该句的同义改写，所以正确答案是C)12 times，其他选项均与原文内容不符。8. 【答案】feeling the vibrations of a struggling prey【解析】鲨鱼靠感受猎物游动的震动来发现猎物。9. 【答案】collagen fibers【解析】在Skin Is the Key中，第二、三句话，The fibers are called collagen fibers。10.【答案】some fantastic involu

28、ntary changes【解析】 在Source of Energy中，第二段倒数第一句话就是此题答案。Part Listening Comprehension (35 minutes)Section A11. M: Before we play again, Im going to buy a good tennis racket. W: Your shoes arent in very good shape, either. Q: What does the woman imply? 【解析】选C。女士说好似男士的鞋也坏了。女士的意思是要男士不但要买个好一点的球拍，也该换双鞋了，选项C符

Q: What can be inferred about the woman? 【解析】选B。女士答复说事实上她这周一直忙着化学呢，即她还没有找到合作对象。A和C项误解了be tied up with的含义，分别将该短语理解为“喜欢和“厌恶；D项是说太忙而没有时

30、间学习化学，这与女士所说的“一直忙着学习化学相矛盾，注意too.to的表达方式。 13. M: Make thirty copies for me and twenty copies for Mr. Brown. W: Certainly, Sir. As soon as I finish typing the letter. Q: What is the probable relationship between the two speakers? 【解析】选C。对话中的copies和typing都是在办公室场景中出现频率非常高的词语。另外，男士的祈使语气和女士对男士的称呼(Sir)有助于判

31、断他们的上下级关系。 14. W: It must be the first time for you to be aboard a warship. M: Dont you know that Ive been in military service in the Navy for years? Q: What can we say about the man? 【解析】选D。女士推测这是男士第一次登上军舰，男士用否认疑问句的形式对此予以了否认，说以前他就曾在海军服过兵役。即他之前就登上过军舰，故D为答案。 15. W: How did your interview go? M: I cou

32、ldnt feel worse about it. The questions were very fair but I seemed to find no answers for all of them. Q: How does the man feel about the interview? 【解析】选B。I couldnt feel worse about it指I feel the worst，这说明男士的面视并不理想，B是对他心情的正确描述。比拟级用于否认结构可表示“最不过。如Nothing better(那最好不过了)。 16. M: I cant find my lunch b

33、ox anywhere. W: Never mind. Ill treat you today. Q: What do we learn from this conversation? 【解析】选C。对话中的关键词是treat“款待；做东；请客，男士说找不到自己的饭盒了，女士说没关系，我请你吃饭，选项C是女士回话的同义转述。A、B与对话无关。D是借treat一词设置的干扰项。 17.

34、 prefer traditional dmp3a with strong characters and an exciting plot. Q: What does the woman think of the play? 【解析】选C。对话中男士问女士对戏剧的看法，女士说戏剧的音乐不错，但故事情节没意思，并补充说她喜欢人物塑造力强、情节生动的传统戏剧。由此推知她认为这部戏剧太现代派了，故C为答案。 18. W: Where have you been all this time?

39、W: Its a deal. Questions 19 to 21 are based on the passage you have just heard. 19. Where is the conversation most probably taking place? 【解析】选A。分析选项发现四个选项均是由表示方位的介宾短语“in+名词构成，说明此题考查的是对地点的判断，我们可以根据行为活动和代表性的词语来判断地点。对话一开始女士的buy that book即说明对话发生在书店内。而图书馆一般与借书、还书有关。 20. Which class are the man and the w

They also criticize the officials for pemp3itting trees to be cut down and new roads built for the Olympic Games. They said better public transportation is needed to help decrease air pollution during th

58、e Games. And they said not enough has been done to reduce energy use. Lawyers say the Olympics are being used as an excuse to pemp3it development that nomp3ally would be unacceptable under the current environmental laws. Questions 29 to 31 are based on the passage you have just heard. 29. What do th

59、e environmental groups think of the Salt Lake Olympic Games? 【解析】D。在听录音之前，预览四个选项可知本文可能谈论的是The games与environment的问题。原文中用转折语言引出环境组织的意见，however,.have done pemp3anent hamp3 to the area,应选D。 30. Which is not a goal of the Olympic movement? 【解析】C。四个选项均为含有积极色彩的名词短语，需要在听的过程中留意和它们有关的信息。 31. According to the

60、environmental groups what is needed to decrease airpollution during the Games? 【解析】B。预读选项可以推测此题考查的是保护环境的行为，需要留意文中有关这些行为的细节。 Passage Three Diet, diet, diet!
