Passage OneWhy don't birds get lost on their long migratory (迁徙) flight? Scientists have

Passage One

Why don't birds get lost on their long migratory (迁徙) flight? Scientists have puzzled over this question for many years. Now they are beginning to fill in the blanks.

Not long ago, experiments showed that birds rely on the sun to guide them during day-light hours. But what about birds that fly mainly by night? Tests with artificial (人造的) stars have proved conclusively that certain night-flying birds are able to follow stars in their long-distance flights.

One such bird--a warbler--had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use stars for guidance. The bird's cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the artificial stars caused a change in the direction of his flight.

Scientists think that warblers, when flying in daylight, use the sun for guidance. But stars are apparently their main means of directed flight in the night. What do they do when stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines and river courses. But when it is too dark to see these, the warblers circle helplessly, unable to find their way.

Which of the following is NOT true about migratory birds' flight?

A.Some birds fly mainly by night.

B.Some birds fly mainly by day.

C.Birds depend on the sun or stars to guide them.

D.Birds like to fly during daylight hours.

Humankind’s future safety and longevity of life on Earth largely depend on the environment which we live. Keeping the air we 1 breathe free of pollution is a major priority towards making this earth a safe place. Other areas of concern are water, land, the ozone layer, and the preservation of flora and fauna of the planet. Every country has ecological issues to deal. In South America, 2 the rain forests are rapidly disappearing as people burn and cut down trees to make for farmland. Many Middle-Eastern and Asian countries 3 have a battle to fight with air, water, and land pollution. Lakes and swamps are spread with debris. 4 Mass chemical spraying is used to kill pests on trees and plants. Abundant 5 use of water in countries as China has caused major water shortage. 6 Rivers become polluted by factories and the populations that live on their banks. Global warming is considered a major factor caused the droughts 7 in eastern China, the Sudan, Ethiopia, and northern Kenya. The reduction of the ozone layer is blamed for the global warming trends in variant countries of this globe, 8 and the spread of disease like skin cancer. Societies at large need to pay attention to the existing problems in order to get of the imminent danger of famine, 9 drought and diseases that rise from the damage that pollution causes. 10

【简答题】Religion and Rationality Yet the difference in tome and language must strike us, so soon as it is philosophy that speaks: that change should remind usthat even if the function of religion and that of reason coincide,this function is performed in the two cases by very different organs. Religions are many, reason one. Religion consists of conscious ideas, hopes, enthusiasms, and objects of worship; it operates by grace and flourishes by prayer. Reason, on the other hand, is a mere principle or potential order, on which indeed we may come to reflect but which exists in us ideally only, without variation or stress of any kind. We conform or do not conform to it; it does not urge or chide us, not call for any emotions on our part other than those naturally aroused by the various objects which it unfolds in their true nature and proportion.Religion brings some order into life by weighting it with new materials. Reason adds to the natural materials only the perfect order which it introduces into them. Rationality is nothing but a form, anideal constitution which experience may more or less embody. Religion is a part of experience itself,a mass of sentiments and ideas. The one is an inviolate principle, the other a changing and struggling force. And yet this struggling and changing force of religion seems to direct man toward something eternal. It seems to make for an ultimate harmony within the soul and for an ultimate harmony between the soul and all that the soul depends upon. Religion, in its intent, is a more conscious and direct pursuit of the Life of Reason than is society, science, or art, for these approach and fill out the ideal life tentatively and piecemeal, hardly regarding the foal or caring forthe ultimate justification of the instinctive aims. Religion also has an instinctive and blind side and bubbles up in all manner of chance practices and intuitions; soon, however, it feels its way towardthe heart of things, and from whatever quarter it may come, veers in the direction of the ultimate. Nevertheless, we must confess that this religious pursuit of the Life of Reason has been singularly abortive. Those within the pale of each religion may prevail upon themselves, to express satisfaction with its results, thanks to a fond partiality in reading the past and generous draughts of hope for the future; but any one regarding the various religions at once and comparing their achievements with what reason requires, must feel how terrible is the disappointment which they have one and all prepared for mankind. Their chief anxiety has been to offer imaginary remediesfor mortal ills, some of which are incurable essentially, while others might have been really cured bywell-directed effort. The Greed oracles, for instance, pretended to heal out natural ignorance, whichhas its appropriate though difficult cure, while the Christian vision of heaven pretended to be anantidote to our natural death—the inevitable correlate of birth and of a changing and conditioned existence. By methods of this sort little can be done for the real betterment of life. To confuse intelligence and dislocate sentiment by gratuitous fictions is a short-sighted way of pursuing happiness. Nature is soon avenged. An unhealthy exaltation and a one-sided morality have to befollowed by regrettable reactions. When these come. The real rewards of life may seem vain to arelaxed vitality, and the very name of virtue may irritate young spirits untrained in and natural excellence. Thus religion too often debauches the morality it comes to sanction and impedes the science it ought to fulfill. What is the secret of this ineptitude? Why does religion, so near to rationality in its purpose, fall soshort of it in its results? The answer is easy; religion pursues rationality through the imagination.When it explains events or assigns causes, it is an imaginative substitute for science. When it gives precepts, insinuates ideals, or remoulds aspiration, it is an imaginative substitute for wisdom—Imean for the deliberate and impartial pursuit of all food. The condition and the aims of life are both represented in religion poetically, but this poetry tends to arrogate to itself literal truth and moral authority, neither of which it possesses. Hence the depth and importance of religion becomes intelligible no less than its contradictions and practical disasters. Its object is the same as that ofreason, but its method is to proceed by intuition and by unchecked poetical conceits. 1. As used in the passage, the author would define “wisdom” as [A] the pursuit of rationality through imagination. [B] an unemotional search for the truth. [C] a purposeful and unbiased quest for what is best. [D] a short-sighted way of pursuing happiness 2. Which of the following statements is NOT TRUE? [A] Religion seeks the truth through imagination, reason, in its search, utilizes the emotions. [B] Religion has proved an ineffective tool in solving man’s problems. [C] Science seeks a piece meal solution to man’s questions. [D] The functions of philosophy and reason are the same. 3. According to the author, science differs from religion in that [A] it is unaware of ultimate goals. [B] it is unimaginative. [C] its findings are exact and final. [D] it resembles society and art. 4. The author states that religion differs from rationality in that [A] it relies on intuition rather than reasoning . [B] it is not concerned with the ultimate justification of its instinctive aims. [C] it has disappointed mankind. [D] it has inspired mankind. 5. According to the author, the pursuit of religion has proved to be [A] imaginative. [B] a provider of hope for the future. [C] a highly intellectual activity [D] ineffectual. 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 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 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. 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 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 coloring, 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, 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 zebra 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 shores, 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. 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 special 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 the 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. seeking the interpretation of these most interesting and elaborate adaptations, attempts have been 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 result 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 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 interpretation 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 become 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 environment (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.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 of a leaf. This method of rendering invisible any part which would interfere with the resemblance is well know in mimicry. 1. The black and white stripes of the zebra are most useful form [A] hunters. [B] nocturnal predators [C] lions and tigers. [C] insectivorous Vertrbrata 2. Aggressive resemblance occurs when [A] a predaceous attitude is assumed. [B] special resemblance is utilized. [C] an animal relies on speed. [D] an animal blends in with its background. 3. Special resemblance differs from general resemblance in that the animal relies on [A] its ability to frighten its adversary. [B] speed. [C] its ability to assume an attitude. [D] mistaken identify 4. The title below that best expresses the ides of this passage is [A] Cryptic coloration for Protection. [B] How Animals Survive. [C] The uses of Mimicry in Nature. [D] Resemblances of Animals.

A man may take drink 4 because he feels himself to be a failure, and then fail all the most 5 completely because he drinks. It is rather the same thing that is happening to the English language. It becomes ugly and inaccurate because our thoughts are foolish, but the sloven of our language 6 makes it easier for us to have foolish thoughts. The point is that the  process is irreversible. Modern English, especially written English, 7 is full of bad habits which spread by imitation and which can be  avoided if one is willing to take the necessary trouble. If one gets  rid of these habits one can think more clearly, and think clearly is a 8 necessary first step towards political regeneration: so that the fight against bad English is not frivolous and is not the exclusive concerning 9 of professional writers. I will come back to this present, and I hope 10 that by that time the meaning of what I have said here will have become clearer.

【简答题】Passage one Stratford-on-Avon, as we all know, has only one industry-William Shakespeare-but there are two distinctly separate and increasingly hostile branches. There is the Royal Shakespeare Company (RSC), which presents superb productions of the plays at the Shakespeare Memorial Theatre on the Avon. And there are the townsfolk who largely live off the tourists who come, not to see the plays, but to look at Anne Hathaway’s Cottage, Shakespeare’s birthplace and the other sights. The worthy residents of Stratford doubt that the theatre adds a penny to their revenue. They frankly dislike the RSC’s actors, them with their long hair and beards and sandals and noisiness. It’s all deliciously ironic when you consider that Shakespeare, who earns their living, was himself anactor (with a beard) and did his share of noise - making. The tourist streams are not entirely separate. The sightseers who come by bus- and often take in Warwick Castle and Blenheim Palace on the side – don’t usually see the plays, and some of them are even surprised to find a theatre in Stratford. However, the playgoers do manage a little sight -seeing along with their play going. It is the playgoers, the RSC contends, who bring in much of the town’s revenue because they spend the night (some of them four or five nights) pouring cash into the hotels and restaurants. The sightseers can take in everything and get out of town by nightfall. The townsfolk don’t see it this way and local council does not contribute directly to the subsidy ofthe Royal Shakespeare Company. Stratford cries poor traditionally. Nevertheless every hotel in town seems to be adding a new wing or cocktail lounge. Hilton is building its own hotel there, which you may be sure will be decorated with Hamlet Hamburger Bars, the Lear Lounge, the Banquo Banqueting Room, and so forth, and will be very expensive. Anyway, the townsfolk can’t understand why the Royal Shakespeare Company needs a subsidy. (The theatre has broken attendance records for three years in a row. Last year its 1,431 seats were 94 per cent occupied all year long and this year they’ll do better.) The reason, of course, is that costs have rocketed and ticket prices have stayed low. It would be a shame to raise prices too much because it would drive away the young people who are Stratford’s most attractive clientele. They come entirely for the plays, not the sights. They all seem to look alike (though they come from all over) –lean, pointed, dedicated faces, wearing jeansand sandals, eating their buns and bedding down for the night on the flagstones outside thetheatre to buy the 20 seats and 80 standing-room tickets held for the sleepers and sold to them when the box office opens at 10:30 a.m. 1. From the first two paragraphs , we learn that A. the townsfolk deny the RSC ’ s contribution to the town’s revenue B. the actors of the RSC imitate Shakespeare on and off stage C. the two branches of the RSC are not on good terms D. the townsfolk earn little from tourism 2. It can be inferred from Paragraph 3 that A. the sightseers cannot visit the Castle and the Palace separately B. the playgoers spend more money than the sightseers C. the sightseers do more shopping than the playgoers D. the playgoers go to no other places in town than the theater 3. By saying “Stratford cries poor traditionally” (Line 2-3, Paragraph 4), the author implies that A. Stratford cannot afford the expansion projects B. Stratford has long been in financial difficulties C. the town is not really short of money D. the townsfolk used to be poorly paid 4. According to the townsfolk, the RSC deserves no subsidy because A. ticket prices can be raised to cover the spending B. the company is financially ill-managed C. the behavior of the actors is not socially acceptable D. the theatre attendance is on the rise 5. From the text we can conclude that the author A. is supportive of both sides B. favors the townsfolk’s view C. takes a detached attitude D. is sympathetic to the RSC. Passage Two Students of United States history, seeking to identify the circumstances that encouraged the emergence of feminist movements, have thoroughly investigated the mid-nineteenth-century American economic and social conditions that affected the status of women. These historians, however, have analyzed less fully the development of specifically feminist ideas and activities during the same period. Furthermore, the ideological origins of feminism in the United States have been obscured because, even when historians did take into account those feminist ideas and activities occurring within the United States, they failed to recognize that feminism was then a truly international movement actually centered in Europe. American feminist activists who have been described as "solitary" and "individual theorists" were in reality connected to a movement -utopian socialism--which was already popularizing feminist ideas in Europe during the two decades that culminated inthe first women's rights conference held at Seneca Falls. New York, in 1848. Thus, a complete understanding of the origins and development of nineteenth-century feminism in the United Statesrequires that the geographical focus be widened to include Europe and that the detailed study already made of social conditions be expanded to include the ideological development of feminism. The earliest and most popular of the utopian socialists were the Saint-Simonians. The specifically feminist part of Saint-Simonianism has, however, been less studied than the group's contribution toearly socialism. This is regrettable on two counts. By 1832 feminism was the central concern ofSaint-Simonianism and entirely absorbed its adherents' energy; hence, by ignoring its feminism. European historians have misunderstood Saint-Simonianism. Moreover, since many feminist ideascan be traced to Saint-Simonianism, European historians' appreciation of later feminism in Franceand the United States remained limited. Saint-Simon's followers, many of whom were women, based their feminism on an interpretation ofhis project to reorganize the globe by replacing brute force with the rule of spiritual powers. Thenew world order would be ruled together by a male, to represent reflection, and a female, to represent sentiment. This complementarity reflects the fact that, while the Saint-Simonians did not reject the belief that there were innate differences between men and women, they nevertheless foresaw an equally important social and political role for both sexes in their Utopia. Only a few Saint-Simonians opposed a definition of sexual equality based on gender distinction. This minority believed that individuals of both sexes were born similar in capacity and character, and they ascribed male-female differences to socialization and education. The envisioned result of both currents of thought, however, was that women would enter public life in the new age and that sexual equality would reward men as well as women with an improved way of life. 1.It can be inferred that the author considers those historians who describe early feminists in the United States as "solitary" to be A insufficiently familiar with the international origins of nineteenth-century American feminist thought B overly concerned with the regional diversity of feminist ideas in the period before 1848 C not focused narrowly enough in their geo-graphical scope D insufficiently aware of the ideological consequences of the Seneca Falls conference 2.According to the passage, which of the following is true of the Seneca Falls conference on women's rights? A It was primarily a product of nineteenth-century Saint-Simonian feminist thought. B It was the work of American activists who were independent of feminists abroad. C It was the culminating achievement of the Utopian socialist movement. D It was a manifestation of an international movement for social change and feminism 3.The author's attitude toward most European historians who have studied the Saint-Simonians is primarily one of A approval of the specific focus of their research B disapproval of their lack of attention to the issue that absorbed most of the Saint-Simonians'energy after 1832 C approval of their general focus on social conditions D disapproval of their lack of attention to links between the Saint-Simonians and their American counterparts 4. It can be inferred from the passage that the author believes that study of Saint-Simonianism is necessary for historians of American feminism because such study A would clarify the ideological origins of those feminist ideas that influenced American feminism B would increase understanding of a movement that deeply influenced the Utopian socialism ofearly American feminists C would focus attention on the most important aspect of Saint-Simonian thought before 1832 D promises to offer insight into a movement that was a direct outgrowth of the Seneca Falls conference of 1848 5. According to the passage, which of the following would be the most accurate description of the society envisioned by most Saint-Simonians? A A society in which women were highly regarded for their extensive education B A society in which the two genders played complementary roles and had equal status C A society in which women did not enter public life D A social order in which a body of men and women would rule together on the basis of their spiritual power
