1、閱讀理解（4） 閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。 (Cryptic Coloring) ? ?Cryptic coloring is by far the commonest use of color in the struggle for existence. It is employed for the purpose of attack (aggressive resemblance or anticryptic coloring ) as well as of defense (protective resemblance or procry

2、ptic coloring ). The fact that the same method concealment, may be used both for attack and defense has been well explained by T.Belt who suggests as an illustration the rapidity of movement which is also made use of by both pursuer and pursued, which is similarly raised to a maximum in both by the

3、gradual dying out of the slowest through a series of generations. Cryptic coloring is commonly associated with other aids in the struggle for life. Thus well-concealed mammals and birds, when discovered, will generally endeavor to escape by speed and will often attempt to defend themselves actively.

4、 On the other hand, small animals which have no means of active defense, such as large, numbers of insects, frequently depend upon concealment alone. Protective resemblance is far commoner among animals than aggressive resemblance, in correspondence with the fact that predaceous forms are as a rule

5、much larger and much less numerous than their prey. In the case of insectivorous Vertebrata and their prey such differences exist in an exaggerated form. Cryptic coloring, whether used for defense of attack, may be either general or special. In general resemblance the animal, in consequence of its c

6、oloring, produces the same effect as its environment, but the conditions do not require any special adaptation of shape and outline. General resemblance is especially common among the animal inhabiting some uniformly colored expanse of the earth’s surface, such as an ocean or a desert. In the former

7、, animals of all shapes are frequently protected by their transparent blue color, on the latter, equally diverse forms are defended by their sandy appearance. The effect of a uniform appearance may be produced by a combination of tints in startling contrast. Thus the black and white stripes of the z

8、ebra blend together at a little distance, and “their proportion is such as exactly to match the pale tint which arid ground possesses when seen by moonlight.” Special resemblance is far commoner than general and is the form which is usually met with on the diversified surface of the earth, on the sh

9、ores, and in shallow water, as well as on the floating masses of algae on the surface of the ocean, such as the Sargasso Sea. In these environments the cryptic coloring of animals is usually aided by special modifications of shape, and by the instinct which leads them to assume particular attitudes.

10、 Complete stillness and the assumption of a certain attitude play an essential part in general resemblance on land; but in special resemblance the attitude is often highly specialized, and perhaps more important than any other element in the complex method by which concealment is effected. In specia

11、l resemblance the combination of coloring, shape, and attitude is such as to produce a more or less exact resemblance to some one of the objects in the environment, such as a leaf of twig, a patch of lichen, a flake of bark. In all cases the resemblance is to some object which is of no interest to t

12、he enemy or prey respectively. The animal is not hidden from view by becoming indistinguishable from its background as in the case of general resemblance, but it is mistaken for some well-know object. In seeking the interpretation of these most interesting and elaborate adaptations, attempts have b

13、een made along two lines. The first seeks to explain the effect as a result of the direct influence of the environment upon the individual (G.L.L.Buffon), or by the inherited effects of efforts and the use and disuse of parts (J.B.P.Lamarck). The second believes that natural selection produced the r

14、esult and afterwards maintained it by the survival of the best concealed in each generation. The former suggestion breaks down when the complex nature of numerous special resemblances is appreciated. Thus the arrangement of colors of many kinds into an appropriate pattern requires the cooperation of

15、 a suitable shape and the rigidly exact adoption of a certain elaborate attitude. The latter is instinctive and thus depends on the central nervous system. The cryptic effect is due to the exact cooperation of all these factors; and in the present state of science, the only possible hole of an inter

16、pretation lies in the theory of natural selection, which can accumulate any and every variation which tends toward survival. A few of the chief types of methods by which concealment is effected may be briefly described. The colors of large numbers of vertebrate animals are darkest on the back and be

17、come gradually lighter on the sides, passing into white on the belly. Abbot H. Thayer has suggested that this gradation obliterates the appearance of solidity, which is due to shadow. The color harmony, which is also essential to concealment, is produced because the back is of the same tint as the e

18、nvironment (e. g. earth), bathed in the cold blue-white of the sky, while the belly, being cold blue-white and bathed in shadow and yellow earth reflections produces the same effects. This method of neutralizing shadow for the purpose of concealment by increased lightness of tint was first suggested

19、 by E.B.Poulton in the case of a larva and a pupa, but he did not appreciate the great importance of the principle. In an analogous method an animal in front of a background of dark shadow may have part of its body obliterated by the existence of a dark tint, the remainder resembling, e.g., a part o

37、rn directions to help people get to where they want to go. But they can also cause a lot of problems, sending you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of t

38、he two. Barry Brown is with the Mobile Life Centre in Stockholm, Sweden. The center studies humancomputer interaction, or HCI, especially communications involving wireless devices. We spoke to Mr Brown by Skype. He told us about an incident involving a friend who had flown to an airport i

39、n the eastern United States. There he borrowed a GPSequipped car to use during his stay. Barry Brown：“And they just plugged in an address and then set off to their destination.” And, then it wasn't until they were driving for thirty minutes that they realized they had put in a destination

40、back on the West Coast where they lived. They actually put their home address in. So again, the_GPS_is_kind_of_“garbage_in_garbage_out”． Mr Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipmen

41、t. Barry Brown：“One problem with many GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place.”

42、 Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people's cars. They wrote a paper b

43、ased on their research. It is called “The Normal, Natural Troubles of Driving with GPS.” Barry Brown: “One of the things that struck us, perhaps the most important thing was that you have to know what you're doing when you use a GPS. There are these new skills that people have developed. There ar

44、e these new competencies that you need to have to be able to use a GPS because they sometimes go wrong.” Barry Brown says this goes against a common belief that GPS systems are for passive drivers who lack navigational (導航) skills. “The Normal, Natural Troubles of Driving with GPS” lists several a

They also include timing issues related to when GPS commands are given. Barry Brown says to make GPS systems better we need a better understanding of how drivers, pass

46、engers and GPS systems work together. 文章大意：本文是一篇說明文。GPS全球定位系統(tǒng)可以幫助人們找到想去的地方，但GPS也會帶來許多問題，所以使用GPS全球定位系統(tǒng)是否可靠變得不確定。 5．What is the best title for this passage? A．Is GPS system reliable to use? B．What is the use of GPS? C．How to make the most of GPS? D．Blame! GPS or Passenger

47、s? 答案：A　標題概括題。文章第一段是全文的主旨段。根據(jù)第一段可知，GPS全球定位系統(tǒng)可以幫助人們找到想去的地方，但GPS也會導致許多問題，所以使用GPS全球定位系統(tǒng)是否可靠變得不確定。所以A項最適合做文章的標題，故答案選A。 6．What is the implication of the underlined part? A．GPS is just a garbage device. B．GPS will not correct human errors. C．GPS adjusts your wrong destination. D．GPS is just as smart

51、 and even some style. What many UGGenthusiasts don't know is that their boots are a breeding ground for bacteria and cause foot problems. Doctors believe the boots, which are particularly popular among young teenage girls, are leading to a rise in the number of people suffering pains in their feet

52、 and knees. Dr. Ian Drysdale, head of the British College of Osteopathic Medicine, believes because the foot does not get the proper support on the inside, it will lead to more ankle, knee, hip and back problems. “These boots are not designed for outside wear. Just because something becomes a trend

53、 or fashionable doesn't mean it's good or right，” he said. “The particular problem with this type of footwear is that it is unsupported. It's a slipper. You wouldn't normally expect to be doing outdoor activities from something that's indoor. If you decide to wear your pajamas outside all the time,

54、someone will come up and say it's not a good idea.” Dr. Drysdale explained that the feet issues become a particular problem among young teenage girls, whose bones are “plastic” and developing when they are growing. “If that structure is developing in an inappropriate way，” he said，“then the ultimate

55、 structure will be deformed.” Mike O'Neill, a consultant surgeon, said，“As the foot slides around, you get wear and tear (磨損) on the joints on the inside of the foot. The ankle is in the wrong position, the thigh bone also changes position, and you get an abnormal movement in the pelvis, which lea

56、ds to back problems.” UGG Australia, who makes the designer version of the boots, told The Daily Wirror that their boots are “comfort” rather than “performance” footwear and consumers should be aware of “knockoffs (仿制品)” which lack reinforced heels in their boots. 文章大意：本文是一篇議論文。文章介紹了雪地靴因它的時尚、舒適、保暖

57、等特性而備受年輕女孩的青睞。但研究人員發(fā)現(xiàn)，在它時尚的外觀背后，隱藏著一些不為人知的健康隱患。 9．Teenage girls prefer to wear UGG boots because of the following EXCEPT ________. A．design 　　B．comfort C．quality D．warmth 答案：C　細節(jié)理解題。根據(jù)文章第一段第一句“... combining function, comfort, warmth and even some style.”可知，A

58、、B、D三項都是年輕女孩喜歡雪地靴的原因。故C項正確。 10．According to Dr. Ian Drysdale, ________. A．there is a possibility that bacteria will multiply in UGG boots B．wearing UGG boots will lead to more ankle and toe problems C．it's not a good idea to wear boots like UGG outside all the time D．teenage girls' bones are pl

59、astic enough to wear UGG boots 答案：C　細節(jié)理解題。根據(jù)文章第三段中“‘These boots are not designed for outside wear. Just because something becomes a trend or fashionable doesn't mean it's good or right，’ he said. ‘The particular problem with this type of footwear is that it is unsupported.’”可知，C項正確。 11．The underli

60、ned word “deformed” is closest in meaning to ________. A．shaped B．strengthened C．reformed D．damaged 答案：D　詞義猜測題。由語境可知，年輕女孩子的骨頭正在發(fā)育，具有一定的可塑性。如果骨骼結(jié)構(gòu)以一種不合適的方式發(fā)育的話，骨骼就會損傷，發(fā)生變形。shaped合適的，有計劃的；strengthened使加強的；reformed革新的；damaged損傷的，毀壞的。此處與倒數(shù)第二段中“back problems”相照應。故D項正確。 12．Which of the following can be the best title for the text? A．Potential Harm of UGG Boots B．The Popularity of UGG Boots C．The Unique Design of UGG Boots D．Benefits of UGG Boots 答案：A　標題概括題。通讀全文可知，本文主要講述了雪地靴對年輕女孩生長發(fā)育過程中所造成的潛在危害。故A項正確。
