一The Earth comprises three principal layers: the dense, iron-rich core, the mantle made of silicate (硅酸盐) that are semi-molten at depth, and the thin,solid-surface crust There are two kinds of crust, a lower and denser oceanic crust and an upper，lighter continental crust found over only about 40 percent of the Earth's surface. The rocks of the crust are of very different ages. Some continental rocks are over 3,000 million years old, while those of the ocean floor are less than 200 million years old. The crusts and the top, solid part of the mantle, totaling about 70 to 100 kilometers in thickness, at present appear to consist of about 15 rigid plates, 7 of which are very large. These plates move over the semi-molten lower mantleto produce all of the major topographical(地形学的)features of the Earth. Active zones where intense deformation occur are confined to the narrow,GAGGAGAGGAFFFFAFAFinterconnecting boundaries of contact of the plates.There are three main types of zones of contact: spreading contacts where plates move apart, converging contacts where plates move towards each other, and transform contacts where plates slide past each other. Newoceanic crust is formed along one or more margins of each plate by material issuing from deeper layers of the Earth' s crust, for example, by volcanic eruptions (爆发) of lava (火山熔岩) at mid-ocean ridges. If at such a spreading contact the two plates support continents，a rift(裂缝) is formed that will gradually widen and become flooded by the tea. The Atlantic Ocean formed like this as the American and Afro-European plates moved in opposite directions. When two plates carrying continents collide, the continentalblocks,too light to be drawn down, continue to float and therefore buckle (起褶皱) to form a mountain chainalong the length of the margin of the plates.GAGGAGAGGAFFFFAFAF練習題：Choose correct answers to the question:1.The Earth’s crust______.A.can be classified into two typesB.is formed along the margins of the platesC.consists of semi-molten rocksD.is about 70 to 100 kilometers thick2.The 15 plates of the Earth are formed from ___.A.the oceanic crusts and continental crustsB.the crusts and the mantleC.the crusts and the top and solid part of the mantleD.the continental crusts and the solid part of the mantle3.Seriously-deformed zones appear _______A.whenever the crusts move over mantleB.when the plates move towards each otherC.in the narrow boundaries where two plates meetGAGGAGAGGAFFFFAFAFD.to be the major topographical feature of theEarth4.According to the second paragraph, the formation of the Atlantic Ocean is the example of_______.A.spreading contactsB.the influence of volcanic eruptionsC.converging contactsD.transform contacts5.This passage is probably_______.A.a newspaper advertisementB.a chapter of a novelC.an excerpt from a textbookD.a scientific report of new findings二A remarkable variety of insects live in this planet More species of insects exist than all other animal species together. Insects have survived on earth formore than 300 million years, and may possess the abilityGAGGAGAGGAFFFFAFAFto survive for millions more.Insects can be found almost everywhere -- on the highest mountains and on the bottom of rushing streams, in the cold South Pole and in bubbling hot springs. They dig through the ground, jump and sing in the trees,and run and dance in the air. They come in many different colors and various shapes. Insects are extremely useful to humans, pollinating (授粉)our crops as well as flowers in meadows, forests, deserts and other areas. But licks and some insects, such as mosquitoes and fleas, can transmit disease.There are many reasons why insects are so successful at surviving. Their amazing ability to adapt permits them to live in extreme ranges of temperatures and environments. The one place they have not yet been found to any major extent is in the open oceans. Insects can survive on a wide range, of natural and artificialfoods—paint, pepper, glue, books, grain, cotton，otherGAGGAGAGGAFFFFAFAFinsects, plants and animals Because they are small theycan hide in tiny spaces.A strong, hard but flexible shell covers their soft organs and is resistant to chemicals, water and physical impact. Their wings give them the option of flying away from dangerous situations or toward food or males. Also, insects have an enormous reproductive capacity: An African ant queen can lay as many as 43,000 eggs a day.Another reason for their success is the strategy of protective color. An insect may be right before our eyes, but nearly invisible because it is cleverly disguised like a green leaf, lump of brown soil, gray lichen (青苔),a seed or some other natural object Some insects use bright, bold colors to send warning signals that they taste bad,sting or are poison.Others have wing patterns that look like the eyes of a huge predator,bitter-tasting insects; hungry enemies are fooled intoGAGGAGAGGAFFFFAFAFavoiding them.練習題：Choose correct answers to the question:1.Insects can be found in large amounts in the following places EXCEPT _____.A.on the mountains with little airB.in the cold polar areasC.in the hot desert areasD.in the open oceans2.Insects protect themselves from chemicals by _______A.hiding in tiny spacesB.having a strong shellC.flying away when necessaryD.changing colors or shapes3.Some insects disguise like natural objects so as to ______A.frighten away their enemiesGAGGAGAGGAFFFFAFAFB.avoid being discoveredC.send warning signalsD.look bitter-tasting4.The passage mentions that insects ______.A.can be found in any extreme environmentsB.have survived longer than any other creaturesC.can be fed on any natural or man-made foodsD.are important for the growth of crops and flowers5.The passage is mainly about ______A.how insects survive in different placesB.why insects can survive so successfullyC.what insects can do to the environmentD.where insects can be found in quantity三The fridge is considered necessary. It has been so since the 1960s when packaged food list appeared withthe label: "Store in the refrigerator."GAGGAGAGGAFFFFAFAFIn my fridge less Fifties childhood, 1 was fedwell and healthy. The milkman came every day, the grocer, the butcher (肉商), the baker, and the ice-cream man delivered two or three times each week. The Sunday meat would last until Wednesday and surplus(剩余的) bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on food deliveries have ceased, fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. Many well-tried techniques already existed -- natural cooling, drying, smoking, salting, sugaring, bottling...What refrigeration did promote was marketing --- marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around theworld in search of a good price.GAGGAGAGGAFFFFAFAFConsequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the rich countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside anartificially-heated house -- while outside, nature provides the desired temperature free of charge.The fridge's effect upon the environment has been evident, while its contribution to human happiness has been not important. If you don't believe me, try it yourself, invest in a food cabinet and mm off your fridge next winter. You may not eat the hamburgers(汉堡包), but at least you'll get rid of that terrible hum.練習題：Choose correct answers to the question:1.The statement "In my fridgeless fiftiesGAGGAGAGGAFFFFAFAFchildhood, I was fed well and healthily." suggeststhat______.A.the author was well-fed and healthy even without a fridge in his fifties.B.the author was not accustomed to fridges even in his fifties.C.there was no fridge in the author's home in the 1950s.D.the fridge was in its early stage of development in the 1950s.2.Why does the author say that nothing was wasted before the invention of fridges?A.People would not buy more food than was necessary.B.Food was delivered to people two or three times a week.C.Food was sold fresh and did not get rotteneasily.GAGGAGAGGAFFFFAFAFD.People had effective ways to preserve their food.3.Who benefited the least from fridges according to the author?A. Inventors.B. Consumers.C. Manufacturers.D. Travelling salesmen.4.Which of the following phrases in the fifth paragraph indicates the fridge's negative effect on the environment?A.“Hum away continuously”.B.“Climatically almost unnecessary”.C.“Artificially-cooled space”.D.“With mild temperatures”.5.What is the author's overall attitude toward fridges?A. Neutral.GAGGAGAGGAFFFFAFAFB. Critical.C. Objective.D. Compromising.四Moreover, insofar as any interpretation of its author can be made from the five or six plays attributed to him, the Wake field Master is uniformly considered to be a man of sharp contemporary observation. He was, formally, perhaps clerically educated, as his Latin and music, his Biblical and patristic lore indicate. He is, still, celebrated mainly for his quick sympathy for the oppressed and forgotten man, his sharp eye for character, a ready ear for colloquial vernacular turns of speech and a humor alternately rude and boisterous, coarse and happy. Hence despite his conscious artistry as manifest in his feeling for intricate metrical and stanza forms, he is looked upon as a kind of medievalSteinbeck, indignantly angry at, uncompromisingly andGAGGAGAGGAFFFFAFAFeven brutally realistic in presenting the plight of theagricultural poor.Thus taking the play and the author together, it is mow fairly conventional to regard the former as a kind of ultimate point in the secularization of the medieval drama. Hence much emphasis on it as depicting realistically humble manners and pastoral life in the bleak hills of the West Riding of Yorkshire on a typically cold bight of December 24th. After what are often regarded as almost “documentaries” given in the three successive monologues of the three shepherds, critics go on to affirm that the realism is then intensified into a burlesque mock-treatment of the Nativity. Finally as a sort of epilogue orafter-thought in deference to the Biblical origins of the materials, the play slides back into an atavistic mood of early innocent reverence. Actually, as we shallsee, the final scene is not only the culminating sceneGAGGAGAGGAFFFFAFAFbut perhaps the raisond’ etre of introductory“realism.”There is much on the surface of the present play to support the conventional view of its mood of secular realism. All the same, the “realism” of the Wake field Master is of a paradoxical turn. His wide knowledge of people, as well as books indicates no cloistered contemplative but one in close relation to his times. Still, that life was after all a predominantly religious one, a time which never neglected the belief that man was a rebellious and sinful creature in need of redemption, So deeply (one can hardly say “naively”of so sophisticated a writer) and implicitly religious is the Master that he is less able (or less willing) to present actual history realistically than is the author of the Brome “Abraham and Isaac”. His historical sense is even less realistic than that of Chaucer whojust a few years before had done for his own time costumeGAGGAGAGGAFFFFAFAFromances, such as The Knight’s Tale, Troilus and Cressida, etc. Moreover Chaucer had the excuse of highly romantic materials for taking liberties with history.1. Which of the following statements about the Wake field Master is NOT True?[A]. He was Chaucer’s contemporary.[B]. He is remembered as the author of five or six realistic plays.[C]. He write like John Steinbeck.[D]. HE was an accomplished artist.2. By “patristic”, the author means[A]. realistic. [B]. patriotic[C]. superstitious. [C]. pertaining to the Christian Fathers.3. The statement about the “secularization of the medieval drama” refers to the[A]. introduction of mundane matters inGAGGAGAGGAFFFFAFAFreligious plays.[B]. presentation of erudite material.[C]. use of contemporary introduction of religious themes in the early days.4. In subsequent paragraphs, we may expect the writer of this passage to[A]. justify his comparison with Steinbeck.[B]. present a point of view which attack the thought of the second paragraph.[C]. point out the anachronisms in the play.[D]. discuss the works of Chaucer.五The earliest controversies about the relationship between photography and art centered on whether photograph’s fidelity to appearances and dependence on a machine allowed it to be a fine art as distinct from merely a practical art. Throughout the nineteenthcentury, the defence of photography was identical withGAGGAGAGGAFFFFAFAFthe struggle to establish it as a fine art. Against thecharge that photography was a soulless, mechanical copying of reality, photographers asserted that it was instead a privileged way of seeing, a revolt against commonplace vision, and no less worthy an art than painting.Ironically, now that photography is securely established as a fine art, many photographers find it pretentious or irrelevant to label it as such. Serious photographers variously claim to be finding, recording, impartially observing, witnessing events, exploring themselves—anything but making works of art. They are no longer willing to debate whether photography is or is not a fine art, except to proclaim that their own work is not involved with art. It shows the extent to which they simply take for granted the concept of art imposed by the triumph of Modernism: the better the art,the more subversive it is of the traditional aims ofGAGGAGAGGAFFFFAFAFart.Photographers’ disclaimers of any interest in making art tell us more about the harried status of the contemporary notion of art than about whether photography is or is not art. For example, those photographers who suppose that, by taking pictures, they are getting away from the pretensions of art as exemplified by painting remind us of those Abstract Expression ist painters who imagined they were getting away from the intellectual austerity of classical Modernist painting by concentrating on the physical act of painting. Much of photography’s prestige today derives from the convergence of its aims with those of recent art, particularly with the dismissal of abstract art implicit in the phenomenon of Pop painting during the1960’s. Appreciating photographs is a relief to sensibilities tired of the mental exertions demandedby abstract art. Classical Modernist painting—that is,GAGGAGAGGAFFFFAFAFabstract art as developed indifferent ways by Picasso, Kandinsky, and Matisse—presupposes highly developed skills of looking and a familiarity with other paintings and the history of art. Photography, like Pop painting, reassures viewers that art is not hard; photography seems to be more about its subjects than about art.Photography, however, has developed all the anxieties and self-consciousness of a classic Modernist art. Many professionals privately have begun to worry that the promotion of photography as an activity subversive of the traditional pretensions of art has gone so far that the public will forget that photography is a distinctive and exalted activity—in short, an art.1. What is the author mainly concerned with? The author is concerned with[A]. defining the Modernist attitude towardGAGGAGAGGAFFFFAFAFart.[B]. explaining how photography emerged as a fine art.[C]. explaining the attitude of serious contemporary photographers toward photography as art and placing those attitudes in their historical context.[D]. defining the various approaches that serious contemporary photographers take toward their art and assessing the value of each of those approaches.2. Which of the following adjectives best describes “the concept of art imposed by the triumph of Modernism” as the author represents it in lines 12—13?[A]. Objective [B]. Mechanical. [C]. Superficial. [D]. Paradoxical.3. Why does the author introduce AbstractExpressionist painter?GAGGAGAGGAFFFFAFAF[A]. He wants to provide an example of artistswho, like serious contemporary photographers, disavowed traditionally accepted aims of modern art.[B]. He wants to set forth an analogy between the Abstract Expressionist painters and classical Modernist painters.[C]. He wants to provide a contrast to Pop artist and others.[D]. He wants to provide an explanation of why serious photography, like other contemporary visual forms, is not and should not pretend to be an art.4. How did the nineteenth-century defenders of photography stress the photography?[A]. They stressed photography was a means of making people happy.[B]. It was art for recording the world.[C]. It was a device for observing the worldimpartially.GAGGAGAGGAFFFFAFAF[D]. It was an art comparable to painting.六The past ages of man have all been carefully labeled by anthropologists. Descriptions like‘ Palaeolithic Man’, ‘Neolithic Man’, etc., neatly sum up whole periods. When the time comes for anthropologists to turn their attention to the twentieth century, they will surely choose the label ‘Legless Man’. Histories of the time will go something like this: ‘in the twentieth century, people forgot how to use their legs. Men and women moved about in cars, buses and trains from a very early age. There were lifts and escalators in all large buildings to prevent people from walking. This situation was forced upon earth dwellers of that time because of miles each day. But the surprising thing is that they didn’t use their legs even when they went on holiday. They built cablerailways, ski-lifts and roads to the top of every hugeGAGGAGAGGAFFFFAFAFmountain. All the beauty spots on earth were marred bythe presence of large car parks. ’The future history books might also record that we were deprived of the use of our eyes. In our hurry to get from one place to another, we failed to see anything on the way. Air travel gives you a bird’s-eye view of the world – or even less if the wing of the aircraft happens to get in your way. When you travel by car or train a blurred image of the countryside constantly smears the windows. Car drivers, in particular, are forever obsessed with the urge to go on and on: they never want to stop. Is it the lure of the great motorways, or what? And as for sea travel, it hardly deserves mention. It is perfectly summed up in the words of the old song: ‘I joined the navy to see the world, and what did I see? I saw the sea.’ The typical twentieth-century traveler is the man whoalways says ‘I’ve been there. ’ You mention theGAGGAGAGGAFFFFAFAFremotest, most evocative place-names in the world likeEl Dorado, Kabul, Irkutsk and someone is bound to say ‘I’ve been there’– meaning, ‘I drove through it at 100 miles an hour on the way to somewhere else. ’When you travel at high speeds, the present means nothing: you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend all experience; the present ceases to be a reality: you might just as well be dead. The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving are one and the same thing: he arrives somewhere with every step he makes. He experiences the present moment with his eyes, his ears and the whole of his body. At the end of his journey he feels adelicious physical weariness. He knows that sound.GAGGAGAGGAFFFFAFAFSatisfying sleep will be his: the just reward of all true travellers.1、Anthorpologists label nowaday’s men‘Legless’ because________.A people forget how to use his legs.B people prefer cars, buses and trains.C lifts and escalators prevent people from walking.D there are a lot of transportation devices.2、Travelling at high speed means________.A people’s focus on the future.B a pleasure.C satisfying drivers’ great thrill.D a necessity of life.3、Why does the author say ‘we are deprived of the use of our eyes’ ?A People won’t use their eyes.B In traveling at high speed, eyes becomeGAGGAGAGGAFFFFAFAFuseless.C People can’t see anything on his way of travel.D People want to sleep during travelling.4、What is the purpose of the author in writing this passage?A Legs become weaker.B Modern means of transportation make the world a small place.C There is no need to use eyes.D The best way to travel is on foot.5. What does ‘a bird’s-eye view’ mean?A See view with bird’s eyes.B A bird looks at a beautiful view.C It is a general view from a high position looking down.D A scenic place.七Advertisers tend to think big and perhaps this isGAGGAGAGGAFFFFAFAFwhy they’re always coming in for criticism. Theircritics seem to resent them because they have a flair for self-promotion and because they have so much money to throw around. ‘It’s iniquitous,’ they say, ‘that this entirely unproductive industry (if we can call it that) should absorb millions of pounds each year. It only goes to show how much profit the big companies are making. Why don’t they stop advertising and reduce the price of their goods? After all, it’s the consumer who pays…’The poor old consumer! He’d have to pay a great deal more if advertising didn’t create mass markets for products. It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods. Another equally important function is to inform. A great deal of the knowledgewe have about household goods derives largely from theGAGGAGAGGAFFFFAFAFadvertisements we read. Advertisements introduce us to new products or remind us of the existence of ones we already know about. Supposing you wanted to buy a washing machine, it is more than likely you would obtain details regarding performance, price, etc., from an advertisement.Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would you enjoy gazing at a blank wall or reading railway bye laws while waiting for a train? Would you like to read only closely printed columns of news in your daily paper? A cheerful, witty advertisement makes such a difference to a drab wall or a newspaper full of the daily ration of calamities.We must not forget, either, that advertising makesGAGGAGAGGAFFFFAFAFa positive contribution to our pockets. Newspapers,commercial radio and television companies could not subsist without this source of revenue. The fact that we pay so little for our daily paper, or can enjoy so many broadcast program mes is due entirely to the money spent by advertisers. Just think what a newspaper would cost if we had to pay its full price!Another thing we mustn’t forget is the ‘small ads.’which are in virtually every newspaper and magazine. What a tremendously useful service they perform for the community! Just about anything can be accomplished through these columns. For instance, you can find a job, buy or sell a house, announce a birth, marriage or death in what used to be called the ‘hatch, match and dispatch’ column but by far the most fascinating section is the personal or‘agony’ column. No other item in a newspaper provides such entertaining readingor offers such a deep insight into human nature. It’GAGGAGAGGAFFFFAFAFs the best advertisement for advertising there is!1. What is main idea of this passage?A. Advertisement.B. The benefits of advertisement.C. Advertisers perform a useful service to communities.D. The costs of advertisement.2. The attitude of the author toward advertisers is______.A. appreciative.B. trustworthy.C. critical.D. dissatisfactory.3. Why do the critics criticize advertisers?A. Because advertisers often brag.B. Because critics think advertisement is a “waste of money”.C. Because customers are encouraged to buy moreGAGGAGAGGAFFFFAFAFthan necessary.D. Because customers pay more.4. Which of the following is Not True?A. Advertisement makes contribution to our pockets and we may know everything.B. We can buy what we want.C. Good quality products don’t need to be advertised.D. Advertisement makes our life colorful.5. The passage is______.A. Narration.B. Description.C. Criticism.D. Argumentation.八Science is a dominant theme in our culture. Since it touches almost every facet of our life, educatedpeople need at least some acquaintance with itsGAGGAGAGGAFFFFAFAFstructure and operation. They should also have anunderstanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist.This book is written for the intelligent student or lay person whose acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse of dried facts; for the person who sees the chief objective of science as the production of gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or – independently of any course –simply to provide a better understanding of science.GAGGAGAGGAFFFFAFAFWe hope this book will lead readers to a broaderperspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture.We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not an unique incident but, rather, part of the trend evident in all segments of society as more women entertraditionally male-dominated fields and makeGAGGAGAGGAFFFFAFAFsignificant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far form being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally.We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn’t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earna living.1. According to the passage, ‘scientificGAGGAGAGGAFFFFAFAF。
