1、阅读理解（4）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。(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 procryptic col

2、oring ). 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 gradual

3、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. On the

4、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 much lar

5、ger 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 coloring,

6、 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 earths surface, such as an ocean or a desert. In the former, animals

7、 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 zebra blen

8、d 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 shores, and

9、 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. Complete

10、 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 special resembl

11、ance 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 the enemy

12、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 been made al

13、ong 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 result and a

14、fterwards 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 a suitable

15、 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 interpretation l

16、ies 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 become gradua

17、lly 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 environment

18、(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 by E.B.Pou

19、lton 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 of a leaf. T

25、追捕动物和被追的动物也利用快速的动作。这种快速的运动同样是通过几代更迭，逐渐消除了慢速，而发展到快速顶峰。2. Protective resemblance is far commoner among animals than aggressive resemblance, in correspondence with the fact that predaceous forms are as a rule much larger and much less numerous than their prey.参考译文 保护性模仿远比侵犯行模仿要普遍得多，这是和下述的情况想配合的：食肉的（形式）

26、动物，按惯律总是比他们捕食的对象要大而且多得多。3. The effect of a uniform appearance may be produced by a combination of tints in startling contrast.参考译文 在惊人的对比中，色泽的综合可能产生外形一致的效果。4. their proportion is such as exactly to match the pale tint which arid ground possesses when seen by moonlight.参考译文 （这里指斑马的黑白条）比例正好和在月光下观看贫瘠土地

27、所具有的苍白色泽相吻合。5. 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.参考译文 在这些环境中，动物的保护色常常得到特定的形状变化和本能的协作，这种本能会使动物采取特定的姿势。6. Complete stillness and the assumption of a certain attit

28、ude play an essential part in general resemblance on land; but in special resemblance the attitude is often highly specialized参考译文绝对静态和采取一般姿势在陆地的一般模仿中起很大作用，而在专门模仿中，姿势常常是高度专门化的。7.

30、election, which can accumulate any and every variation which tends toward survival.参考译文 保护效果是由于所以这些因素确切合作而形成。根据目前科学水平，唯一的解释（此种现象）就是自然选择理论，它可以累积要生存的各种变异/变种。写作方法与文章大意文章以一般到具体的协作和分类方式写作，第一段点出生物界生存竞争中最常用的一种颜色是保护色，保护色可分为两类：进犯（进攻）型和防卫型。一般是防御性保护色多于进攻型。而两种类型都可归纳为一般性模仿和专门（特定）模仿。居住（栖息）在单一色泽的地方的动物，如海洋或沙漠，常采用模仿

31、性保护色如透明的绿色，土色等，而特定摸刚的动物则栖息在多样性的地方，如海岸，浅水，海洋表面等。特定模仿还需要有改变形状姿势之协作，使其看起来像客观环境中的某物，某种身份mistaken identify.第二段涉及有关模仿性的解释的探索，结果为二。一种观点是环境直接影响的结果。第二种是自然选择的结果。当人们理解了许多特定模仿的复杂特性时，第一种解释就不能成立了。这说明保护效果是一切因素合适的外形和某种精心设计的姿势等合作而成。按现在科学水平来解释，只能归之“自然选择”理论，然后是用具体例子来证实。答案祥解1.

34、day driving in many countries. These satellitebased systems provide turnbyturn 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

35、responsible. Most often, says Barry Brown, it is a combination of the 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 in

36、cident involving a friend who had flown to an airport in 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 wasnt until they were driving for thirty minutes that t

37、hey realized they had put in a destination 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 shortcom

38、ings, or failures, of GPS equipment.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 its go

39、ing to the wrong place.”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 peoples cars. They

40、wrote a paper based 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 youre doing when you use a GPS. There are these new skills that people have developed

41、. There are 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 (导航) skills.“The Normal, Natural Troubles of Driving with GPS” lists sev

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,

43、passengers and GPS systems work together.文章大意：本文是一篇说明文。GPS全球定位系统可以帮助人们找到想去的地方，但GPS也会带来许多问题，所以使用GPS全球定位系统是否可靠变得不确定。5What is the best title for this passage?AIs GPS system reliable to use? BWhat is the use of GPS?CHow to make the most of GPS? DBlame! GPS or Passengers?答案：A标题概括题。文章第一段是全文的主旨段。根据第一段可知，GP

44、S全球定位系统可以帮助人们找到想去的地方，但GPS也会导致许多问题，所以使用GPS全球定位系统是否可靠变得不确定。所以A项最适合做文章的标题，故答案选A。6What is the implication of the underlined part?AGPS is just a garbage device.BGPS will not correct human errors.CGPS adjusts your wrong destination.DGPS is just as smart as human beings.答案：B句意理解题。根据画线句子后面一句“Mr Brown says t

45、his is a common human error.”并结合上下文可知，画线句子所包含的意思是：GPS不能纠正人类的错误。故答案选B。7Which is NOT mentioned as a GPS shortcoming in the passage?ASmall screen. BTiming of commands.COutdated maps. DDear cameras GPS uses.答案：D细节理解题。根据文章第五段第一句可知，A项是GPS的缺点；根据文章倒数第二段可知，B、C两项均是GPS的缺点。所以只有D项不是GPS的缺点。故答案选D。8According to the

46、 passage, people commonly believe that _.Ayou have to know where to go when using GPSByou need to have new competencies to use GPS wellCGPS is proper for drivers with little sense of directionDGPS is fit for people having good understanding of maps答案：C推理判断题。通读全文可知，人们普遍认为，GPS全球定位系统适合方向感差的人。C项符合文义，故答案选C。阅读下列短文, 从给的四个选项 (A、B、C和D) 中, 选出最佳选项。(2013东北三省三校第二次联考，C)UGG boots have been a winterweather fashion for several years now, combining function, comfort, warm
