Passage One % >;#9"O4
Questions1—8 are based on the following passage: ?bw4 ~
In the two decades between 1910 and 1930, over ten percent of the Black population of the United States left the South, where the preponderance of the Black population had been located, and migrated to northern states, with the largest number moving, it is claimed, between 1916 and 1918. It has been frequently assumed, but not proved, that the majority of the migrants in what has come to be called the Great Migration came from rural areas and were motivated by two concurrent factors: the collapse of the cotton industry following the boll weevil infestation, which began in 1898, and increased demand in the North for labor following the cessation of European immigration caused by the outbreak of the First World War in 1914. This assumption has led to the conclusion that the migrants’ subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills. `-3o+ID\
But the question of who actually left the South has never been rigorously investigated. Although numerous investigations document an exodus from rural southern areas to southern cities prior to the Great Migration, no one has considered whether the same migrants then moved on to northern cities. In 1910 over 600,000 Black workers, or ten percent of the Black work force, reported themselves to be engaged in “manufacturing and mechanical pursuits,” the federal census category encompassing the entire industrial sector. The Great Migration could easily have been made up entirely of this group and their families. It is perhaps surprising to argue that an employed population could be enticed to move, but an explanation lies in the labor conditions then prevalent in the South. wb Iq&>p
About thirty-five percent of the urban Black population in the South was engaged in skilled trades. Some were from the old artisan class of slavery—blacksmiths, masons, carpenters—which had had a monopoly of certain trades, but they were gradually being pushed out by competition, mechanization, and obsolescence. The remaining sixty-five percent, more recently urbanized, worked in newly developed industries—tobacco, lumber, coal and iron manufacture, and railroads. Wages in the South, however, were low, and Black workers were aware, through labor recruiters and the Black press, that they could earn more even as unskilled workers in the North than they could as artisans in the South. After the boll weevil infestation, urban Black workers faced competition from the continuing influx of both Black and White rural workers, who were driven to undercut the wages formerly paid for industrial fobs. Thus, a move north would be seen as advantageous to a group that was already urbanized and steadily employed, and the easy conclusion tying their subsequent economic problems in the North to their rural background comes into question. {)AMw q

Passage Two cD1o"bq
Question 9—17 are based on the following passage: ihT~ xt
Prior to 1975, union efforts to organize public-sector clerical worker, most of whom are women, were somewhat limited. The factors favoring unionization drives seem to have been either the presence of large numbers of workers, as in New York City, to make it worth the effort, or the concentration of small numbers in one or two locations, such as a hospital, to make it relatively easy. Receptivity to unionization on the workers, part was also a consideration, but when there were large numbers involved or the clerical workers were the only unorganized group in a jurisdiction, the multioccupational unions would often try to organize them regardless of the workers’ initial receptivity. The strategic reasoning was based, first, on the concern that politicians and administrators might play off unionized against nonunionized workers, and, second, on the conviction that a fully unionized public work force meant power, both at the bargaining table and in the legislature. In localities where clerical workers were few in number, were scattered in several workplaces, and expressed no interest in being organized, unions more often than not ignored them in the pre-1975 period. %[<Y9g,:Q
But since the mid-1970’s, a different strategy has emerged. In 1977,34 percent of government clerical workers were represented by a labor organization, compared with 46percent of government professionals, 44 percent of government blue-collar workers, and 41 percent of government service workers. Since then, however, the biggest increases in public-sector unionization have been among clerical workers. Between 1977 and 1980, the number of unionized government workers in blue-collar and service occupations increased only about 1.5 percent, while in the white-collar occupations the increase was 20 percent and among clerical workers in particular, the increase was 22 percent. !\[+99F#
What accounts for this upsurge in unionization among clerical workers? First, more women have entered the work force in the past few years, and more of them plan to remain working until retirement age. Consequently, they are probably more concerned than their predecessors were about job security and economic benefits. Also, the women’s movement has succeeded in legitimizing the economic and political activism of women of their own behalf, thereby producing a more positive attitude toward unions. The absence of any comparable increase in unionization among private-sector clerical worker, however, identifies the primary catalyst — the structural change in the multioccupational public-sector unions themselves. Over the past twenty years, the occupational distribution in these unions has been steadily shifting from predominantly blue-collar to predominantly white-collar. Because there are far more women in white-collar jobs, an increase in the proportion of female members has accompanied the occupational shift and has altered union policy-making in favor of organizing women and addressing women’s issues.

Passage Three +Jw{qQ R/*
Questions 18—24 are based on the following passage: aF])" 9
Studies of the Weddell seal in the laboratory have described the physiological mechanisms that allow the seal to cope with the extreme oxygen deprivation that occurs during its longest dives, which can extend 500 meters below the ocean’s surface and last for over 70 minutes. Recent field studies, however, suggest that during more typical dives in the wild, this seal’s physiological behavior is different. ;: _(7|
In the laboratory, when the seal dives below the surface of the water and stops breathing, its heart beats more slowly, requiring less oxygen and its arteries become constricted, ensuring that the seal’s blood remains concentrated near those organs most crucial to its ability to navigate underwater. The seal essentially shuts off the flow of blood to other organs, which either stop functioning until the seal surfaces or switch to an anaerobic (oxygen-independent) metabolism. The latter results in the production of large amounts of lactic acid which can adversely affect the PH of the seal’s blood but since the anaerobic metabolism occurs only in those tissues which have been isolated from the seal’s blood supply, the lactic acid is released into the seal’s blood only after the seal surfaces, when the lungs, liver, and other organs quickly clear the acid from the seal’s blood stream. xKW"X
Recent field studies, however, reveal that on dives in the wild, the seal usually heads directly for its prey and returns to the surface in less than twenty minutes. The absence of high levels of lactic acid in the seal’s blood after such dives suggests that during them, the seal’s organs do not resort to the anaerobic metabolism observed in the laboratory, but are supplied with oxygen from the blood. The seal’s longer excursions underwater, during which it appears to be either exploring distant routes or evading a predator, do evoke the diving response seen in the laboratory. But why do the seal’s laboratory dives always evoke this response, regardless of their length or depth? Some biologists speculate that because in laboratory dives the seal is forcibly submerged, it does not know how long it will remain underwater and so prepares for the worst. TSXTc'

Passage Four @RQ+JYQi
Questions 25—30 are based on the following passage: "hz >{oe
Australian researchers have discovered electroreceptors (sensory organs designed to respond to electrical fields) clustered at the tip of the spiny anteater’s snout. The researchers made this discovery by exposing small areas of the snout to extremely weak electrical fields and recording the transmission of resulting nervous activity to the brain. While it is true that tactile receptors, another kind of sensory organ on the anteater’s snout, can also respond to electrical stimuli, such receptors do so only in response to electrical field strengths about 1,000 times greater than those known to excite electroreceptors. v)TUg0U=,
Having discovered the electroreceptors, researchers are now investigating how anteaters utilize such a sophisticated sensory system. In one behavioral experiment, researchers successfully trained an anteater to distinguish between two troughs of water, one with a weak electrical field and the other with none. Such evidence is consistent with researcher’s hypothesis that anteaters use electroreceptors to detect electrical signals given off by prey; however, researchers as yet have been unable to detect electrical signals emanating from termite mounds, where the favorite food of anteaters live. Still, researchers have observed anteaters breaking into a nest of ants at an oblique angle and quickly locating nesting chambers. This ability quickly to locate unseen prey suggests, according to the researchers, that the anteaters were using their electroreceptors to locate the nesting chambers. g+VRT, r

Passage Five kMfc"JXF
Questions 31—35 are based on the following passage: OX
#eLco
Coral reefs are one of the most fragile, biologically complex, and diverse marine ecosystem on Earth. This ecosystem is one of the fascinating paradoxes of the biosphere: how do clear, and thus nutrient-poor waters support such prolific and productive communities? Part of the answer lies within the tissues of the corals themselves. Symbiotic cells of algae known as zoozanthellae carry out photosynthesis using the metabolic wastes of the coral thereby producing food for themselves, for their corals, hosts, and even for other members of the reef community. This symbiotic process allows organisms in the reef community to use sparse nutrient resource efficiently. 4eDmLC"Y
*
Unfortunately for coral reefs, however, a variety of human activities are causing worldwide degradation of shallow marine habitats by adding nutrients to the water. Agriculture, slash—and —burn land clearing, sewage disposal and manufacturing that creates waste by-products all increase nutrient loads in these waters. Typical symptoms of reef decline are destabilized herbivore populations and an in creasing abundance of algae and filetr-feeding animals. Declines in reef communities are consistent with observations that nutrient input is increasing in direct proportion to growing human populations, thereby threatening reef communities sensitive to subtle changes in nutrient input to their waters.

Passage Six RL]lt0O{
Questions 36 to 40 are based on the following passage. Vqv2F @.
For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the U.S had acquired when it purchased Louisiana, and the Appolo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war. {ZBb. $}RC
Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. #Ko+_Hm?4
Today Mars looms as humanity’s next great terra incognita. And with doubtful prospects for a short-term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet’s reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take leading role? The question naturally invites a couple of others: Are there experiments that only humans could do on Mars? Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space? S9ak '
With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe. ay7+H7^|hZ

Passage One DBrzw+;e3
The distinction between the mechanization of the past and what is happening now is, however, not a sharp one. At one extreme we have the electronic computer with its quite remarkable capacity for discrimination and control, while at the other end of the scale are “transfer machines”, as they are now called, which may be as simple as a conveyor belt to another. An automatic mechanism is one which has a capacity for self-regulation; that is, it can regulate or control the system or process without the need for constant human attention or adjustment. Now people often talk about “feedback” as being an essential factor of the new industrial techniques, upon which is based an automatic self-regulating system and by virtue of which any deviation in the system from desired conditions can be detected, measured, reported and corrected. When “feedback” is applied to the process by which a large digital computer runs at the immense speed through a long series of sums, constantly rejecting the answers until it finds one to fit a complex set of facts which have been put to it, it is perhaps different in degree from what we have previously been accustomed to machines.

Passage Two B46H@]d#7K
The Internet, once the domain of education and government, has suddenly exploded into the commercial sector. From this we will witness dramatic changes in the way we work and the systems we will use. Java will have a very important role to play in this digital revolution allowing executable content that are safe to traverse and ride the Internet onto our desktops.

A rich, interactive, three-dimensional “Second Web” is expected to evolve which will help to attract a larger audience than today’s two-dimensional text-pictures model. K

New technologies are already beginning to transform the World Wide Web from its page-centric system to one more like the real world-interactive, three-dimensional and animated. ump:dL5{
“The First Web is primarily a medium for document access. It is fundamentally a reading experience with benefits often expressed in the savings achieved by eliminating paper-based processes. As a result, the Web applies to a limited part of our lives. It has not become a mass medium for the home like telephones and television sets. f7AJSHe

Passage Three yT9RNo/w
In order to meet the global challenges in today’s highly competitive environment, a firm’s strategic cost management programs should not restrict their attention to the cost structure of the firm or the firm’s cost performance relative to that of other firms and, in particular, competitors. ?@BaBU:o`F
There are two benefits that can be derived from such extra-organizational cost analysis. The first benefit is a steady stream of ideas that can be used to make a firm more efficient and its products more competitive. These benefits are derived from all aspects of extra-organizational cost analysis, but especially from product teardown and participation in roundtables. The second benefit is a comparison of a firm’s own progress at becoming efficient with the progress of other firms. BCDf9]X

To our view, the future belongs to those who will know how to perceive the mysterious borderline which separates the ugly from the beautiful. This philosophy has dominated most of the great civilizations of the past and is fundamentally our own western way of looking at the world. *ww(5 t

It is only through stronger ties among all of us, through the realization of a truly triangular world of cooperative effort in which the United States, Europe, and Japan will be able to reinforce their respective ties, that one will be capable of planning the general scenario of the 21 st century, and this within a broader picture of international cooperation among all civilized people of this planet. iYs?B0*JWK

科学的最终目的是提供一种描绘整个宇宙的简单理论。然而，大多科学家实际采用的方法是将这个问题分成两个部分。第一部分是一些告知我们宇宙随着时间的推移而变化的方式的规律。第二部分是对宇宙初始状态的疑问。有些人认为科学只应该关注第一部分。他们把宇宙初始状态的问题看成是玄学或宗教要回答的问题。 xJ5!` #=

1. Computer viruses are created by a small group of evil hackers who write harmful softwares in the spirit/for the sake of fun/hoax. The viruses are short-line software codes, with the following three features: first, they hide themselves among legal documents or programs; second, they can copy themselves like bacteria to be transferred between computers; third, their effect on your computers will drive you crazy/ make you mad.

2. The ultimate aim of science is to obtain a simple theory which describes the whole universe. However, most scientists in effect separate the issue into two parts. The first part consists of laws which tell us how the universe changes with time. The second part consists of the questions over the original state of the universe. Some people believe that science should only focus on the first part whereas the questions over the original state of the universe should be solved by metaphysics or religions. -zkL)< 7

1． 降雪开始后若要持续，就必须有持续不断的湿气流充当凝结核。气流经过水面再上升到较高大气层而形成湿气。太平洋是落基山西部大部分降雪形成的湿气来源，而墨西哥湾和大西洋则为美国中部、东部地区气流形成提供水汽。一些地貌也是大雪湿气形成的原因。例如：五大湖区附近地区有着独特的湖效应风雪，这是由当地地形决定的。另外，山体截面及上升地势也会导致湿气气流上升而引起降雪。 cYS+XBz
2． 乔伊斯•卡罗•奥茨1963年出版了第一本短篇故事集《北门》。两年前，她已在威斯康星大学获得硕士学位，成为了底特律大学的一名英语教师。自此，她著作颇丰，不到二十年的时间写了近三十本书，其中包括小说、短篇故事集及诗集、戏剧及文艺评论。同时，她仍旧从事教学工作，于1967年自底特律大学转到安大略湖区的温得森大学任教，又于1978年到了普林斯顿大学。评论家羡慕她巨大的创作能力，同时认为要对如此数量巨大的作品进行评价真的是很困难。 Jtk(yp{Zz
3． 在广大的宇宙中，一些恒星在一刻不停的悸动着，而另一些恒星已耗尽了自己的能量，正在膨胀、变红直到吞没周围的行星（如果它们有行星的话）。（亿万年后，我们的太阳也将膨胀，地球将变得易碎、干枯并且蒸发成铁蒸气及石头，所有生命迹象都将消失）。一些恒星发生爆炸，发出强烈的宇宙射线，以近光速向外冲出，经过数千光年到达地球，提供物种突变的一些驱动力，从而促进了生物的进化。 ~]+

4． 即使身处电子时代中，当计算机以量化的方法来分析历史的时候，我仍将勇敢地说，我认为，量化应用于历史研究有其局限性。量化依靠的方法是“资料处理”，即将过去的历史事实、资料（即人类行为）经处理分成特定的范畴，如此它们就可以被编程输入计算机中了。人们希望由此可获得一种结果——一种规律。而我只能告诉你，对历史而言，“资料处理”必然会导致无效的结论，因为在处理资料时，某种程度上，你需修改资料迎合外来的要求，在这里就是机器的需求。这样你的处理结果将会受到人们的怀疑，并有失真的可能。 izo

In the 21 century, office work can be done anywhere: on holiday, we will bring wireless mobile phones or portable computers with us, and some even take mobile phones to the concert or meeting room because to them, it is a mistake that can not be compensable to miss an important commercial information. The 24 hours of super Internet Time makes it impossible to rest and think calmly. More and more executives take pride in having time for sleep, because in their view, the biggest symbol of status is represented by the ability to work and rest according to the natural biological clock rather than the network clock. |/Z)?
Of course, it is impossible to retreat from information age to agricultural age. To me, the correct attitude is to be the master rather than the slave of the time by conforming to the time. We have to learn to arrange our life according to our biological clock in the internet time, instead of chasing the ever-rising network sun. To chase the network sun without stop for 24 hours is a demonstration of your inaptitude, burning a candle at two ends. )S?}huX

However the clone of panda arouses great interest from people because of the ruthless fact that panda is in the edge of extinction due to its weak ability of multiplication. The clone of panda should not replace the natural multiplication of pandas; on the contrary, it serves as a reinforcement for natural and artificial multiplications. As long as the clone is beneficial to the protection of the panda, it is worth trying. ,Yz+?SmSZ&
Even when we successfully complete a clone of panda, more efforts shall be made to improve the clone technology which is still in the stage of research rather than production. What the scientists shall do is to learn from experiments to improve the research. The research on cloning panda will contribute to the development of clone technology. Once it succeeds, it can be employed to save other endangered animals.
