2018年可锐考研英语经典阅读试题（五）[物理学]The use of heat pumps has been held back largely by skepticism about advertisers’claims that heat pumps can provide as many as two units of thermal energy for each unit of electrical energy used, thus apparently contradicting the principle of energy conservation.Heat pumps circulate a fluid refrigerant that cycles alternatively from its liquid phase to its vapor phase in a closed loop. The refrigerant, starting as a low-temperature, low-pressure vapor, enters a compressor driven by an electric motor. The refrigerant leaves the compressor as a hot, dense vapor and flows through a heat exchanger called the condenser, which transfers heat from the refrigerant to a body of air. Now the refrigerant, as a high-pressure, cooled liquid, confronts a flow restriction which causes the pressure to drop. As the pressure falls, the refrigerant expands and partially vaporizes, becoming chilled. It then passes through a second heat exchanger, the evaporator, which transfers heat from the air to the refrigerant, reducing the temperature of this second body of air. Of the two heat exchangers, one is located inside, and the other one outside the house, so each is in contact with a different body of air: room air and outside air, respectively.The flow direction of refrigerant through a heat pump is controlled by valves. When the refrigerant flow is reversed, the heat exchangers switch function. This flow-reversal capability allows heat pumps either to heat or cool room air.Now, if under certain conditions a heat pump puts out more thermal energy than it consumes in electrical energy, has the law of energy conservation been challenged? No, not even remotely: the additional input of thermal energy into the circulating refrigerant via the evaporator accounts for the difference in the energy equation.Unfortunately there is one real problem. The heating capacity of a heat pump decreases as the outdoor temperature falls. The drop in capacity is caused by the lessening amount of refrigerant mass moved through the compressor at one time. The heating capacity is proportional to this mass flow rate: the less the mass of refrigerant being compressed, the less the thermal load it can transfer through the heat-pump cycle. The volume flow rate of refrigerant vapor through the single-speed rotary compressor used in heat pumps is approximately constant. But cold refrigerant vapor entering a compressor is at lower pressure than warmer vapor. Therefore, the mass of cold refrigerant —and thus the thermal energy it carries —is less than if the refrigerant vapor were warmer before compression.Here, then, lies a genuine drawback of heat pumps: in extremely cold climates —where the most heat is needed —heat pumps are least able to supply enough heat.1. The primary purpose of the text is to[A] explain the differences in the working of a heat pump when the outdoor temperature changes.[B] contrast the heating and the cooling modes of heat pumps.[C] describe heat pumps, their use, and factors affecting their use.[D] advocate the more widespread use of heat pumps.2. The author resolves the question of whether heat pumps run counter to the principle of energy conservation by[A] carefully qualifying the meaning of that principle.[B] pointing out a factual effort in the statement that gives rise to this question.[C] supplying additional relevant facts.[D] denying the relevance of that principle to heat pumps.3. It can be inferred from the text that, in the course of a heating season, the heating capacity of a heat pump is greatest when[A] heating is least essential.[B] electricity rates are lowest.[C] its compressor runs the fastest.[D] outdoor temperatures hold steady.4. If the author’s assessment of the use of heat pumps is correct, which of the following best expresses the lesson that advertisers should learn from this case?[A] Do not make exaggerated claims about the products you are trying to promote.[B] Focus your advertising campaign on vague analogies and veiled implications instead of on facts.[C] Do not use facts in your advertising that will strain the prospective client’s ability to believe.[D] Do not assume in your advertising that the prospective clients know even the mostelementary scientific principles.5. The text suggests that heat pumps would be used more widely if[A] they could also be used as air conditioners.[B] they could be moved around to supply heat where it is most needed.[C] their heat output could be thermostatically controlled.[D] people appreciated the role of the evaporator in the energy equation.[历史学]Traditionally, the study of history has had fixed boundaries and focal points —periods, countries, dramatic events, and great leaders. It also has had clear and firm notions of scholarly procedure: how one inquires into a historical problem, how one presents and documents one’s findings, what constitutes admissible and adequate proof.Anyone who has followed recent historical literature can testify to the revolution that is taking place in historical studies. The currently fashionable subjects come directly from the sociology catalog: childhood, work, leisure. The new subjects are accompanied by new methods. Where history once was primarily narrative, it is now entirely analytic. The old questions “What happened?”and “How did it happen?”have given way to the question “Why did it happen?”Prominent among the methods used to answer the question “Why”is psychoanalysis, and its use has given rise to psychohistory.Psychohistory does not merely use psychological explanations in historical contexts. Historians have always used such explanations when they were appropriate and when there was sufficient evidence for them. But this pragmatic use of psychology is not what psychohistorians intend. They are committed, not just to psychology in general, but to Freudian psychoanalysis. This commitment precludes a commitment to history as historians have always understood it. Psychohistory derives its “facts”not from history, the detailed records of events and their consequences, but from psychoanalysis of the individuals who made history, and deduces its theories not from this or that instance in their lives, but from a view of human nature that transcends history. It denies the basic criterion of historical evidence: that evidence be publicly accessible to, and therefore assessable by, all historians. And it violates the basic tenet of historical method: that historians be alert to the negative instances that would refute their theses. Psychohistorians, convinced of the absolute rightness of their own theories, are also convinced that theirs is the “deepest”explanation of any event, that other explanations fall short of the truth.Psychohistory is not content to violate the discipline of history ; it also violates the past itself. It denies to the past an integrity and will of its own, in which people acted out of a variety of motives and in which events had a multiplicity of causes and effects. It imposes upon the past the same determinism that it imposes upon the present, thus robbing people and events of their individuality and of their complexity. Instead of respecting the particularity of the past, it assimilates all events, past and present, into a single deterministic schema that is presumed to be true at all times and in all circumstances.1. Which of the following best states the main point of the text?[A] The approach of psychohistorians to historical study is currently in vogue even though it lacks the rigor and verifiability of traditional historical method.[B] Traditional historians can benefit from studying the techniques and findings of psychohistorians.[C] Areas of sociological study such as childhood and work are of little interest to traditional historians.[D] The psychological assessment of an individual’s behavior and attitudes is more informative than the details of his or her daily life.2. The author mentions which of the following as a characteristic of the practice of psychohistorians?[A] The lives of historical figures are presented in episodic rather than narrative form.[B] Archives used by psychohistorians to gather material are not accessible to other scholars.[C] Past and current events are all placed within the same deterministic diagram.[D] Events in the adult life of a historical figure are seen to be more consequential than are those in the childhood of the figure.3. The author of the text suggests that psychohistorians view history primarily as[A] a report of events, causes, and effects that is generally accepted by historians but which is, for the most part, unverifiable.[B] an episodic account that lacks cohesion because records of the role of childhood, work, and leisure in the lives of historical figures are rare.[C] an uncharted sea of seemingly unexplainable events that have meaning only when examined as discrete units.[D] a record the way in which a closed set of immutable psychological laws seems to have shaped events.4. The author of the text puts the word “deepest”in quotation marks most probably in order to[A] signal her reservations about the accuracy of psychohistorians’claims for their work.[B] draw attention to a contradiction in the psychohistorians’method.[C] emphasize the major difference between the traditional historians’method and that of psychohistorians.[D] disassociate her opinion of the psychohistorians’claims from her opinion of their method.5. In presenting her analysis, the author does all of the following EXCEPT.[A] Make general statements without reference to specific examples.[B] Describe some of the criteria employed by traditional historians.[C] Question the adequacy of the psychohistorians’interpretation of events.[D] Point out inconsistencies in the psychohistorians’application of their methods.。

2018年可锐考研英语经典阅读试题（一）[经济学类]Recent years have brought minority-owned businesses in the United States unprecedented opportunities —as well as new and significant risks. Civil rights activists have long argued that one of the principal reasons why Blacks, Hispanics, and other minority groups have difficulty establishing themselves in business is that they lack access to the sizable orders and subcontracts that are generated by large companies. Now Congress, in apparent agreement, has required by law that businesses awarded federal contracts of more than $500,000 do their best to find minority subcontractors and record their efforts to do so on forms filed with the government. Indeed, some federal and local agencies have gone so far as to set specific percentage goals for apportioning parts of public works contracts to minority enterprises.Corporate response appears to have been substantial. According to figures collected in 1977, the total of corporate contracts with minority businesses rose from $77 million in 1972 to $1.1 billion in 1977. The projected total of corporate contracts with minority businesses for the early 1980’s is estimated to be over 53 billion per year with no letup anticipated in the next decade.Promising as it is for minority businesses, this increased patronage poses dangers for them, too. First, minority firms risk expanding too fast and overextending themselves financially, since most are small concerns and, unlike large businesses, they often need to make substantial investments in new plants, staff, equipment, and the like in order to perform work subcontracted to them. If, thereafter, their subcontracts are for some reason reduced, such firms can face potentially crippling fixed expenses. The world of corporate purchasing can be frustrating for small entrepreneurs who get requests for elaborate formal estimates and bids. Both consume valuable time and resources, and a small company’s efforts must soon result in orders, or both the morale and the financial health of the business will suffer.A second risk is that White-owned companies may seek to cash in on the increasing apportionments through formation of joint ventures with minority-owned concerns. Of course, in many instances there are legitimate reasons for joint ventures; clearly, White and minority enterprises can team up to acquire business that neither could acquire alone. But civil rights groups and minority business owners have complained to Congress about minorities being set up as “fronts”with White backing, rather than being accepted as full partners in legitimate joint ventures.Third, a minority enterprise that secures the business of one large corporate customer often run the danger of becoming- and remaining-dependent. Even in the best of circumstances, fierce competition from larger, more established companies makes it difficult for small concerns to broaden their customer bases: when such firms have nearly guaranteed orders from a single corporate benefactor, they may truly have to struggle against complacency arising from their current success.1. The primary purpose of the text is to[A] present a commonplace idea and its inaccuracies.[B] describe a situation and its potential drawbacks.[C] propose a temporary solution to a problem.[D] analyze a frequent source of disagreement.2. The text suggests that the failure of a large business to have its bids for subcontracts result quickly in orders might causes it to[A] experience frustration but not serious financial harm.[B] face potentially crippling fixed expenses.[C] have to record its efforts on forms filed with the government.[D] increase its spending with minority subcontractors.3. It can be inferred from the text that, compared with the requirements of law, the percentage goals set by “some federal and local agencies”are[A] more popular with large corporations.[B] more concrete.[C] less controversial.[D] less expensive to enforce.4. Which of the following, if true, would most weaken the author’s assertion that, in the 1970’s, corporate response to federal requirements was substantial?[A] Corporate contracts with minority-owned businesses totaled $2 billion in 1979.[B] Between 1970 and 1972, corporate contracts with minority-owned businesses declined by 25 percent.[C] The figures collected in 1977 underrepresented the extent of corporate contracts with minority-owned businesses.[D] The $1.1 billion represented the same percentage of total corporate spending in 1977 asdid $77 million in 1972.5. The author would most likely agree with which of the following statements about corporate response to working with minority subcontractors?[A] Annoyed by the proliferation of “front”organizations, corporations are likely to reduce their efforts to work with minority-owned subcontractors in the near future.[B] Although corporations showed considerable interest in working with minority businesses in the 1970’s, their aversion to government paperwork made them reluctant to pursue many government contracts.[C] The significant response of corporations in the 1970’s is likely to be sustained and conceivably be increased throughout the 1980’s.[D] Although corporations are eager to cooperate with minority-owned businesses, a shortage of capital in the 1970’s made substantial response impossible.二．The fossil remains of the first flying vertebrates, the pterosaurs, have intrigued paleontologists for more than two centuries. How such large creatures, which weighed in some cases as much as a piloted hang-glider and had wingspans from 8 to 12 meters, solved the problems of powered flight, and exactly what these creatures were —reptiles or birds —are among the questions scientists have puzzled over.Perhaps the least controversial assertion about the pterosaurs is that they were reptiles. Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. In pterosaurs a greatly elongated fourth finger of each forelimb supported a winglike membrane. The other fingers were short and reptilian, with sharpclaws. In birds the second finger is the principal strut of the wing, which consists primarily of feathers. If the pterosaurs walked on all fours, the three short fingers may have been employed for grasping. When a pterosaur walked or remained stationary, the fourth finger, and with it the wing, could only turn upward in an extended inverted V shape along each side of the animal’s body.The pterosaurs resembled both birds and bats in their overall structure and proportions. This is not surprising because the design of any flying vertebrate is subject to aerodynamic constraints. Both the pterosaurs and the birds have hollow bones, a feature that represents a savings in weight. In the birds, however, these bones are reinforced more massively by internal struts.Although scales typically cover reptiles, the pterosaurs probably had hairy coats. T. H. Huxley reasoned that flying vertebrates must have been warm-blooded because flying implies a high rate of metabolism, which in turn implies a high internal temperature. Huxley speculated that a coatof hair would insulate against loss of body heat and might streamline the body to reduce drag in flight. The recent discovery of a pterosaur specimen covered in long, dense, and relatively thick hairlike fossil material was the first clear evidence that his reasoning was correct.Efforts to explain how the pterosaurs became airborne have led to suggestions that they launched themselves by jumping from cliffs, by dropping from trees, or even by rising into light winds from the crests of waves. Each hypothesis has its difficulties. The first wrongly assumes that the pterosaurs’hind feet resembled a bat’s and could serve as hooks by which the animal could hang in preparation for flight. The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings. The third calls for high waves to channel updrafts. The wind that made such waves however, might have been too strong for the pterosaurs to control their flight once airborne.1. It can be inferred from the text that scientist now generally agree that the[A] enormous wingspan of the pterosaurs enabled them to fly great distances.[B] structure of the skeleton of the pterosaurs suggests a close evolutionary relationship to bats.[C] fossil remains of the pterosaurs reveal how they solved the problem of powered flight.[D] pterosaurs were reptiles.2. The author views the idea that the pterosaurs became airborne by rising into light winds created by waves as[A] revolutionary.[B] unlikely.[C] unassailable.[D] probable.3. According to the text, the skeleton of a pterosaur can be distinguished from that of a bird by the[A] size of its wingspan.[B] presence of hollow spaces in its bones.[C] anatomic origin of its wing strut.[D] presence of hooklike projections on its hind feet.4. The ideas attributed to T. H. Huxley in the text suggest that he would most likely agree with which of the following statements?[A] An animal’s brain size has little bearing on its ability to master complex behaviors.[B] An animal’s appearance is often influenced by environmental requirements and physical capabilities.[C] Animals within a given family group are unlikely to change their appearance dramatically over a period of time.[D] The origin of flight in vertebrates was an accidental development rather than the outcome of specialization or adaptation.5. Which of the following best describes the organization of the last paragraph of the text?[A] New evidence is introduced to support a traditional point of view.[B] Three explanations for a phenomenon are presented and each is disputed by means of specific information.[C] Three hypotheses are outlined and evidence supporting each is given.[D] Recent discoveries are described and their implications for future study are projected.。
2018年可锐考研第一轮复习之英语阅读
2018年可锐考研第一轮复习之英语阅读（一）Until about five years ago, the very idea that peptide hormonesmight be made anywhere in the brain besides the hypothalamus was astounding.Peptide hormones, scientists thought, were made by endocrine glands and thehypothalamus was thought to be the brains’only endocrinegland. What is more, because peptide hormones cannot cross the blood-brainbarrier, researchers believed that they never got to any part of the brainother than the hypothalamus, where they were simply produced and then releasedinto the bloodstream. But these beliefs about peptide hormones were questioned aslaboratory after laboratory found that antiserums to peptide hormones, wheninjected into the brain, bind in places other than the hypothalamus, indicatingthat either the hormones or substances that cross-react with the antiserums arepresent. The immunological method of detecting peptide hormones by means ofantiserums, however, is imprecise. Cross-reactions are possible and this methodcannot determine whether the substances detected by the antiserums really arethe hormones, or merely close relatives. Furthermore, this method cannot beused to determine the location in the body where the detected substances areactually produced. New techniques of molecular biology, however, provide a way toanswer these questions. It is possible to make specific complementary DNA’s that canserve as molecular probes seek out the messenger RNA’s of thepeptide hormones. If brain cells are making the hormones, the cells will containthese mRNA’s. If the products the brain cells make resemble the hormones butare not identical to them, then the c DNA’s should still bindto these mRNA’s, but should not bind as tightly as they would to m RNA’s for thetrue hormones. The cells containing these mRNA’s can then beisolated and their mRNA’s decoded to determine just what their protein products are and howclosely the products resemble the true peptide hormones. The molecular approach to detecting peptide hormones using cDNAprobes should also be much faster than the immunological method because it cantake years of tedious purifications to isolate peptide hormones and thendevelop antiserums to them. Roberts, expressing the sentiment of manyresearchers, states: “I was trained as an endocrinologist. But it became clear to me thatthe field of endocrinology needed molecular biology input. The process ofgrinding out protein purifications is just too slow.”If, as the initial tests with cDNA probes suggest, peptide hormonesreally are made in brain in areas other than the hypothalamus, a theory must bedeveloped that explains their function in the brain. Some have suggested thatthe hormones are all growth regulators, but Rosen’s work on rat brainsindicates that this cannot be true. A number of other researchers propose thatthey might be used for intercellular communication in the brain.1.Which of the following titles best summarizes the text?[A] Is Molecular Biology the Key to Understanding Intercellular Communicationin the Brain?[B] Molecular Biology: Can Researchers Exploit Its Techniques to SynthesizePeptide Hormones?[C] The Advantages and Disadvantages of the Immunological Approach to DetectingPeptide Hormones. [D] Peptide Hormones: How Scientists Are Attempting to Solve Problems of TheirDetection and to Understand Their Function?2.The text suggests that a substance detected in the brain by use of antiserumsto peptide hormones may [A] have been stored in the brain for a long period of time. [B]play no role in the functioning of the brain. [C] have been produced in some part of the body other than the brain. [D] have escaped detection by molecular methods.3.According to the text, confirmation of the belief that peptide hormones arecreated in the brain in areas other than the hypothalamus would forcescientists to [A] reject the theory that peptide hormones are made by endocrine glands. [B] revise their beliefs about the ability of antiserums to detect peptidehormones. [C] invent techniques that would allow them to locate accurately brain cellsthat produce peptide hormones. [D] develop a theory that account for the role played by peptide hormones inthe brain.4.Which of the following is mentioned in the text as a drawback of theimmunological method of detecting peptide hormones? [A] It cannot be used to detect the presence of growth regulators in the brain. [B] It cannot distinguish between the peptide hormones and substances that arevery similar to them. [C] It uses antiserums that are unable to cross the blood-brain barrier. [D] It involves a purification process that requires extensive training inendocrinology.5.The idea that the field of endocrinology can gain from developments inmolecular biology is regarded by Roberts with [A] incredulity. [B] derision. [C] indifference.[D] enthusiasm.[答案与考点解析]1.【答案】D 【考点解析】这是一道中心主旨题。
2018年可锐考研英语阅读真题范文
2018年可锐考研英语阅读真题范文（七）Don’t shoot the messengerThey poison the mind and corrupt the morals of the young, who waste their time sitting on sofas immersed in dangerous fantasy worlds. That, at least, was the charge levelled against novels during the 18th century by critics worried about the impact of a new medium on young people. Today the idea that novels can harm people sounds daft. And that is surely how history will judge modern criticism of video games, which are accused of turning young people into violent criminals. This week European justice ministers met to discuss how best to restrict the sale of violent games to children. Some countries, such as Germany, believe the answer is to ban some games altogether. That is going too far. Criticism of games is merely the latest example of a tendency to demonise new and unfamiliar forms of entertainment. In 1816 waltzing was condemned as a fatal contagion that encouraged promiscuity; in 1910 films were denounced as an evil pure and simple, destructive of social interchange in the 1950s rock ’n’roll music was said to turn young people into devil worshippers and comic books were accused of turning children into drug addicts and criminals. In each case the pattern is the same: young people adopt a new form of entertainment, older people are spooked by its unfamiliarity and condemn it, but eventually the young grow up and the new medium becomes accepted-at which point another example appears and the cycle begins again. The opposition to video games is founded on the mistaken belief that most gamers are children. In fact, twothirds of gamers are over 18 and the average gamer is around 30. But the assumption that gamers are mostly children leads to a double standard. Violent films are permitted and the notion that some films are unsuitable for children is generally understood. Yet different rules are applied to games. Aren’t games different because they are interactive? It is true that video games can make people feel excited or aggressive, but so do many sports. There is no evidence that videogaming causes longterm aggression. Games ought to be agerated, just as films are, and retailers should not sell adultrated games to children any more than they should sell them adultrated films. Ratings schemes are already in place, and in some countries restrictions on the sale of adultrated games to minors have the force of law. Oddly enough, Hillary Clinton, one of the politicians who has led the criticism of the gaming industry in America, has recently come round to this view. Last month she emphasised the need for parents to pay more attention to game ratings and called on the industry, retailers and parents to work together. But this week some European politicians seemed to be moving in the other direction: the Netherlands may follow Germany, for example, in banning some games outright. Not all adults wish to play violent games, just as not all of them enjoy violent movies. But they should be free to do so if they wish.二．Doughnut adjust your setHAVE you ever seen anything on television that made you shout or shake your fist in anger at the screen? Televisions are, of course, unable to respond to such reactions. But that could beabout to change. Controlling your television and other home entertainment devices using voice commands or gestures is starting to become possible thanks to a new generation of controllers.Consider, for example, the controller that went on sale last month with Nintendo’s Wii games console. In place of the usual combination of buttons and joysticks, the Wii has a motionsensitive controller. The console can determine how the controller is moving in space and what it is pointing at, and uses that information to control what is happening on screen. Depending on the game, the controller becomes a warrior’s sword or a golf club.For some games, the controller connects up via a cable to a second, smaller handset called the Nunchuk after the weapon favoured by Bruce Lee in his martial arts movies . It is then possible to use one controller for movement, and the other to fire weapons or use items. The number of buttons on both controllers has been reduced to a minimum, as Nintendo hopes to draw in new customers who find existing games consoles too complicated. But whether the Wii will introduce a generation of grandmothers to the joys of karate games remains to be seen.This living room overload is likely to get worse as telecoms operators launch a new generation of television over broadband services, using a technology called IPTV. This will make possible thousands of channels, downloadable programs and films, plus messaging, internet access and games. It will also involve the biggest and most complicated controllers ever seen. The experience isn’t as good as it could be, says Michael Cai of Parks Associates, a consultancy. So some companies believe a new approach is needed.Other companies have looked at using speech based controllers in the living room. One firm, Promptu, developed a voice control system for American cable operators and tested it in conjunction with Motorola, which makes set top boxes. But it has now decided to reposition the technology as a voice based navigation system for mobile phones. A simpler approach is taken by the In Voca voice activated remote control. It is a universal remote control that can recognise 50 separate commands spoken by up to four separate users, from lower volume to Cartoon Network .A recent entry to the field is Apple Computer, a firm renowned for designing elegant, easy to use products. In 2007 it will launch a new device, called the iTV, that acts as a bridge between a television and a computer. It has a deliberately simple remote control that, like Apple’s iconic iPod music player, involves just one button and one wheel. Steve Jobs, the company’s boss, boasts that it is very Apple . Might his company be the one to solve the remote control confusion?三．Behind the bleeding edgeMANKIND’S progress in developing new gizmos is often referred to as the march of technology . That conjures up images of constant and relentless forward movement orchestrated with military precision. In reality, technological progress is rather less orderly. Some technologies do indeed improve at such a predictable pace that they obey simple formulae such as Moore’s law, which acts as a battle plan for the semiconductor industry. Other technologies proceed by painful lurches-think of third generation mobile phones, or new versions of Microsoft Windows. And there are some cases, particularly in the developing world, when technological progress takes the form of a leapfrog.Such leapfrogging involves adopting a new technology directly, and skipping over the earlier, inferior versions of it that came before. By far the best known example is that of mobile phones in the developing world. Fixed line networks are poor or non existent in many developing countries, so people have leapfrogged straight to mobile phones instead. The number of mobile phones now far outstrips the number of fixed line telephones in China, India and sub Saharan Africa.There are other examples. Incandescent light bulbs, introduced in the late 1870s, are slowly being displaced in the developed world by more energy efficient lightemitting diodes , in applications from traffic lights to domestic lighting. LEDs could, however, have an even greater impact in parts of the developing world that lack mains power and electric lighting altogether. LEDs’greater energy efficiency makes it possible to run them from batteries charged by solar panels during the day.Being behind the bleeding edge of technological development can sometimes be a good thing, in short. It means that early versions of a technology, which may be buggy, unreliable or otherwise inferior, can be avoided. America, for example, was the first country to adopt colour television, which explains why American television still looks so bad today: other countries came to the technology later and adopted technically superior standards.The lesson to be drawn from all of this is that it is wrong to assume that developing countries will follow the same technological course as developed nations. Having skipped fixed line telephones, some parts of the world may well skip desktop computers in favour of portable devices, for example. Entire economies may even leapfrog from agriculture straight to hightech industries. That is what happened in Israel, which went from citrus farming to microchips; India, similarly, is doing its best to jump straight to a hightech service economy.Those who anticipate and facilitate leapfrogging can prosper as a result. Those who fail to see it coming risk being jumped over. Kodak, for example, hit by the sudden rise of digital cameras in the developed world, wrongly assumed that it would still be able to sell old fashioned film and film cameras in China instead. But the emerging Chinese middle classes leapfrogged straight to digital cameras-and even those are now outnumbered by camera phones.。

2018年可锐考研英语阅读理解精选（四）Text4The bride and groom, a guitar-wielding rock vixen and a muscle-rippling dragon-slayer, make an odd couple-so it is hardly surprising that nobody expected their marriage. But on December 2nd the video-game companies behind "Guitar Hero" and "World of Warcraft", Activision and Vivendi Games respectively, announced plans for an elaborate merger. Vivendi, a French media group, will pool its games unit, plus $1.7 billion in cash, with Activision; the combined entity will then offer to buy back shares from Activision shareholders, raising Vivendi’s stake in the resulting firm to as much as 68%.Activision’s boss, Bobby Kotick, will remain at the helm of the new company, to be known as Activision Blizzard in recognition of Vivendi’s main gaming asset: its subsidiary Blizzard Entertainment, the firm behind "World of Warcraft", an online swords-and-sorcery game with 9.3m subscribers. The deal was unexpected, but makes excellent strategic sense, says Piers Harding-Rolls of Screen Digest, a consultancy. Activision has long coveted "World of Warcraft", and Vivendi gets a bigger games division and Activision’s talented management team to run it. As well as making sense for both parties, the $18.9 billion deal-the biggest ever in the video-games industry-says a lot about the trends now shaping the business.The first is a push into new markets, especially online multiplayer games, which are particularly popular in Asia, and "casual" games that appeal to people who do not regard themselves as gamers. "World of Warcraft" is the world’s most popular online subscription-based game and is hugely lucrative. Blizzard will have revenues of $1.1 billion this year and operating profits of $520m. "World of Warcraft" is really "a social network with many entertainment components," says Mr Kotick.Similarly, he argues, "Guitar Hero" and other games that use new kinds of controller, rather than the usual buttons and joysticks, are broadening the appeal of gaming by emphasising its social aspects, since they are easy to pick up and can be played with friends. Social gaming, says Mr Kotick, is "the most powerful trend" building new audiences for the industry. He is clearly excited at the prospect of using Blizzard’s expertise to launch an online version of "Guitar Hero" for Asian markets. Online music games such as "Audition Online", which started in South Korea, are "massive in Asia," says Mr Harding-Rolls.A second trend is media groups’increasing interest in gaming. Vivendi owns Universal Music, one of the "big four" record labels. As the record industry’s sales decline, it makes sense to move into gaming, a younger, faster-growing medium with plenty of cross-marketing opportunities. Other media groups are going the same way. Last year Viacom, an American media giant, acquired Harmonix, the company that originally created "Guitar Hero". It has been promoting its new game, "Rock Band", using its MTV music channel. Viacom has also created online virtual worlds that tie in with several of its television programmes, such as "Laguna Beach" and "Pimp My Ride". Disney bought Club Penguin, a virtual world for children, in August. AndTime Warner is involved in gaming via its Warner Bros Home Entertainment division, which publishes its own titles and last month bought TT Games, the British firm behind the "Lego Star Wars" games.1. The merger of these two companies are out of expection because_____.[A] they aim to design marriage games which sound really weird.[B] It is difficult for big companies of two different nations to end up in successful cooperation.[C] Their games are by no means similar to each other in terms of their styles.[D] It would be illegal for them to buy back the shares.2. Why Piers Harding-Rolls thinks this marriage has strategic sense?[A] Activision has been longing to cooperate with "World of Warcraft".[B] Vivendi could get bigger portion and better management resources from Activision.[C] This deal is beneficial to both sides for they can combine their talents to make various games.[D] This deal make them become decisive factor of this industry’s trend in the future.3. The word "lucrative" most probably means_____.[A] profitable[B] luxurious[C] entertaining[D] populous4. The first trend shaping the industry is _____.[A] pushing people online to develop their own games.[B] building new audiences for the new network of games.[C] promoting games with new kinds of controller.[D] expanding the reign of traditional games and creating new market.5.From the two trends we can infer that_____.[A] this merger is a great success because it goes along with both trends.[B] this deal can strengthen both parties to surpass the other media giants..[C] this allied group is powerful enough to shape the industry’s trends.[D] it is indeed of strategic sense to have initiate and carry out the merger篇章剖析：本篇文章讲述了两个游戏公司Activision和Vivendi的联姻。

2018年可锐考研英语阅读真题解析（一）一、从鸡蛋中培养流感疫菌Modern technology has put men on the moon and deciphered the human genome. But when it comes to brewing up flu to make vaccines, science still turns to the incredible edible egg. Ever since the 1940s, vaccine makers have grown large batches of virus inside chicken eggs. But given that some 36,000 Americans die of flu each year, it’s remarkable that our first line of defense is still what Secretary of Health and Human Services Tommy Thompson calls “the cumbersome and archaic egg-based production.”New cell-based technologies are in the pipeline, however, and may finally get the support they need now that the United States is faced with a critical shortage of flu vaccine. Although experts disagree on whether new ways of producing vaccine could have prevented a shortage like the one happening today, there is no doubt that the existing system has serious flaws.Each year, vaccine manufacturers place advance orders for millions of specially grown chicken eggs. Meanwhile, public-health officials monitor circulating strains of flu, and each March they recommend three strains—two influenza A strains and one B strain—for manufacturers to include in vaccines. In the late spring and summer, automated machines inject virus into eggs and later suck out the influenza-rich goop. Virus from the eggs’innards gets killed and processed to remove egg proteins and other contaminants before being packaged into vials for fall shipment.Why has this egg method persisted for six decades? The main reason is that it’s reliable. But even though the eggs are reliable, they have serious drawbacks. One is the long lead time needed to order the eggs. That means it’s hard to make more vaccine in a hurry, in case of a shortage or unexpected outbreak. And eggs may simply be too cumbersome to keep up with the hundreds of millions of doses required to handle the demand for flu vaccine.What’s more, some flu strains don’t grow well in eggs. Last year, scientists were unable to include the Fujian strain in the vaccine formulation. It was a relatively new strain, and manufacturers simply couldn’t find a quick way to adapt it so that it grew well in eggs. “We knew the strain was out there,”recalls Theodore Eickhoff of the University of Colorado Health Sciences Center, “but public-health officials were left without a vaccine—and, consequently, a more severe flu season.”Worse, the viruses that pose the greatest threat might be hardest to grow in eggs. That’s because global pandemics like the one that killed over 50 million people between 1918 and 1920 are thought to occur when a bird influenza changes in a way that lets it cross the species barrier and infect humans. Since humans haven’t encountered the new virus before, they have little protective immunity. The deadly bird flu circulating in Asia in 1997 and 1998, for example,worried public-health officials because it spread to some people who handled birds and killed them—although the bug never circulated among humans. But when scientists tried to make vaccine the old-fashioned way, the bird flu quickly killed the eggs.1.The moon-landing is mentioned in the first paragraph to illustrate_____.[A] technology cannot solve all of our human problems[B] progress in vaccine research for influenza has lagged behind[C] great achievements have been made by men in exploring the unknown[D] the development of vaccine production methods can not be stopped2.What step is essential to the traditional production of flu vaccine?[A] Manufacturers implant the vaccine into ordered chicken eggs.[B] Scientists identify the exact strain soon after a flu pandemic starts.[C] Public health measures are taken as an important pandemic-fighting tool.[D] Viruses are deadened and made clean before being put into vaccine use.3.The foremost reason why the egg-based method is defective lies in_____.[A] the complex process of vaccine production [B] its potential threat to human being[C] the low survival rate for new flu vaccines [D] its contribution to the flu vaccine shortage4.Which of the following is true according to the passage?[A] Flu vaccines now mainly use egg-based technology.[B] A bird influenza has once circulated among humans.[C] Safety can be greatly improved with cell-culture vaccines.[D] Modern vaccine production methods are to replace egg-based methods.5.In the author’s view, the new vaccine production method seems to be_____.[A] remarkable [B] criticized [C] efficient [D] accepted答案：1.B 2.D 3.C 4.A 5.D核心词汇与超纲词汇decipher破译，辨认genome基因组，染色体组brew酿制，沏，煮;~ up酝酿;即将来临cumbersome大而笨重的;繁琐的，复杂的archaic过时的，陈旧的;古代的，早期的in the pipeline在准备中; 在完成中; 在进行中; 运输中; 即将送递circulate循环;传播，流传;传递，传阅strain系，品系，品种innards内脏，内部结构pandemic广泛流传的，普遍的，流行的;传染病的;全国[全世界]性的流行病lead time 前置时间，指完成一个程序或作业所需要的一段时间。

2018年可锐考研英语阅读精选及讲解（三）In the following article, some sentences have been removed. For Questions 1-5, choose the most suitable one from the list A—G to fit into each of the numbered blank. There are two extra choices, which do not fit in any of the gaps. From the seventeenth-century empire of Sweden, the story of a galleon that sank at the start of her maiden voyage in 1628 must be one of the strangest tales of the sea. For nearly three and a half centuries she lay at the bottom of Stockholm harbour until her discovery in 1956. 1) 2) Triple gun-decks mounted sixty-four bronze cannon. She was intended to play a leading role in the growing might of Sweden. As she was prepared for her maiden voyage on August 10,1628, Stockholm was in a ferment. From the Skeppsbron and surrounding islands the people watched this thing of beauty begin to spread her sails and catch the wind. They had laboured for three years to produce this floating work of art; she was more richly carved and ornamented than any previous ship. The high stern castle was a riot of carved gods, demons, knights, kings, warriors, mermaids, cherubs; and zoomorphic animal shapes ablaze with red and gold and blue, symbols of courage, power, and cruelty, were portrayed to stir the imaginations of the superstitious sailors of the day. 3)4) As the wind freshened there came a sudden squall and the ship made a strange movement, listing to port. The Ordnance Officer ordered all the port cannon to be heaved to starboard to counteract the list, but the steepening angle of the decks increased. Then the sound of rumbling thunder reached the watchers on the shore, as cargo,ballast, ammunition and 400 people went sliding and crashing down to the port side of the steeply listing ship. 5)In that first glorious hour, the mighty Vasa, which was intended to rule the Baltic, sank with all flags flying - in the harbour of her birth. [A]All gun-ports were open and the muzzles peeped wickedly from them.[B]Vasa sailed majesticly out of the bay. [C]This was the Vasa, royal flagship of the great imperial fleet. [D]King Gustavus Adolphus, The Northern Hurricane , then at the height of his military success in the Thirty Years War, had dictated her measurements and armament.[E]The lower gun ports were now below water and the inrush sealed the ship s fate. [F] As soon as her discovery, the world became shocken. [G]Then the cannons of the anchored warships thundered a salute to which the Vasa fired in reply. As she emerged from her drifting cloud of gun smoke with the water churned to foam beneath her bow, her flags flying, pennants waving, sails filling in the breeze, and the red and gold of her superstructure ablaze with colour, she presented a more majestic spectacle than Stockholmers had ever seen before. 答案及详解1.C.文章开篇介绍一艘瑞典皇家大船1628年在处女航中沉船，直到1956年才被人们发现。

2018年可锐考研英语阅读真题范文（三）When the cure is not worth the costThanks to research by the National Institutes of Health and academic scientists during the last three decades, we now have proven treatments for depression, addiction and other mental disorders. But all too often clinicians do not use them.Without financial incentives to provide treatments that are known to work, many mental health professionals stick with what they know, or pick up on the latest fad, or even introduce their own untested innovations—which in turn are spread by testimonials and credulous news media coverage.Take the well known approach featured on the cable TV reality show “Intervention”aimed at getting addicts and alcoholics into treatment. Here, the family and sometimes the employer gather with a counselor, confront the addict and threaten to shun him or fire him if he doesn’t enter a rehabilitation center. A 1999 study compared this style of intervention —which can backfire and lead to broken families—to a less confrontational approach known as “community reinforcement and family training,”which is aimed at helping the family nurture the addict’s own motivation.More than twice as many families succeeded in getting their loved ones into treatment with the gentler approach than with standard intervention . But no reality shows push the less dramatic method, and it is difficult to find clinicians who use it.Similarly, one of the most common approaches to alcoholism treatment involves having counselors and fellow alcoholics confront patients and force them to identify themselves as alcoholics. But research finds that the more a counselor confronts, the more a patient drinks and the more likely he is to drop out of treatment. And no association between accepting the label “alcoholic”and quitting drinking has been found. Counselor empathy—not confrontation—is connected with recovery.According to a review by the Institute of Medicine in 2006, only 10.5 percent of alcoholics received “care consistent with scientific knowledge”of the disorder; similarly, 43 percent of children in psychiatric hospitals are given antipsychotic medication despite not suffering from psychosis. Tough boot camps for troubled teenagers—which have been proven to be ineffective and potentially harmful—thrive, while “multisystemic family therapy,”which effectively treats teenagers at home, is available only through the juvenile justice system.If we want to provide genuine help for the 33 million Americans with mental health and drug problems, giving more no strings attached money to providers via insurance mandates is not the answer. It is dangerous to blindly bolster useless and even harmful treatments while failing to support proven therapies. Coverage must be tied to outcomes and evidence. And payment should be dependent, at least in part, on health improvements, not just services received. Weneed parity in evidence based treatment, not just in coverage.二．Limited resourcesIt‘s been nearly a week since Canadian pet food manufacturer Menu Foods Inc. recalled some 60 million cans and pouches of wet food linked to the deaths of at least 15 cats and one dog, yet authorities still can‘t explain exactly what went wrong. Some critics and animal lovers are honing in on what they see as lax regulation of the $15 billion pet food industry in the United States.There‘s almost a void there, says Bob Vetere, president of the American Pet Product Manufacturers Association. There is no real pet food department of any federal agency.Technically, the U.S. Food and Drug Administration is responsible for ensuring that pet foods, like human foods, are safe to eat, truthfully labeled and produced under sanitary conditions. But on Tuesday, FDA officials admitted that the regulation of pet food takes a back seat to its regulatory obligations of other food and drug sectors, and that inspections of pet food processing plants are done only on a for cause basis.There are limited resources, said David Elder, director of the Office of Surveillance and Compliance in the FDA‘s Center for Veterinary Medicine in Rockville, Md. Elder added that inspections of companion animals food products are based on risk , which means that the processing plant in Emporia, Kans., where the tainted food was manufactured, had never been inspected by government officials until after consumers started complaining about pets dying of kidney failure. The Emporia plant remains open and continues to produce new food, according to a Menu Foods spokesperson, who adds that safety tests are being done around the clock.The chief executive of Menu Foods told the Associated Press on Wednesday that the company is looking at one unnamed ingredient as the possible cause of the renal failure. The FDA has previously said the investigation is focusing on possibly contaminated wheat gluten, a common ingredient in pet foods. FDA inspectors have been sent to Menu Foods plants in Kansas and New Jersey.The industry insists their products are absolutely safe. Pet foods are the highest regulated product you‘ll find in the grocery store, says Duane Ekedahl, president of the Pet Food Institute , an industry trade association representing the interests of 20 member companies whose products make up about 97 percent of the dog and cat food produced in the United States. While serious, the Menu Foods recall shouldn‘t be blown out of proportion, says Ekedahl, who points out that the recalled food accounts for less then 2 percent of the overall market. He adds that every pet food company conducts extensive tests, both of incoming raw materials and of finished products. On Tuesday, PFI issued a statement claiming that All cat and dog food products on store shelves are safe. The recall is now complete and all suspected products have been removed fromthe stream of commerce.三．A fuzzy pictureTHIS is a really exciting time-a new era is starting, says Peter Bazalgette, the chief creative officer of Endemol, the television company behind Big Brother and other popular shows. He is referring to the upsurge of interest in mobile television, a nascent industry at the intersection of telecoms and media which offers new opportunities to device makers, content producers and mobile network operators.Already, many mobile operators offer a selection of television channels or individual shows, which are streamed across their third generation networks. In South Korea, television is also sent to mobile phones via satellite and terrestrial broadcast networks, which is far more efficient than sending video across mobile networks. In Europe, the Italian arm of 3, a mobile operator, recently acquired Canale 7, a television channel, with a view to launching mobile TV broadcasts in Italy in the second half of 2006.Meanwhile, Apple Computer, which launched a video capable version of its iPod portable music player in October, is striking deals with television networks to expand the range of shows that can be purchased for viewing on the device, including Lost , Desperate Housewives and Law Order .Despite all this activity, however, the prospects for mobile TV are unclear. For a start, nobody really knows if consumers will pay for it, though surveys suggest they like the idea. Informa, a consultancy, says there will be 125m mobile TV users by 2010. But many other mobile technologies inspired high hopes and then failed to live up to expectations. And even if people do want TV on the move, there is further uncertainty in two areas: technology and business models.At the moment, mobile TV is mostly streamed over 3G networks. But sending an individual data stream to each viewer is inefficient and will be unsustainable in the long run if mobile TV takes off. So the general consensus is that 3G streaming is a prelude to the construction of dedicated mobile TV broadcast networks, which transmit digital TV signals on entirely different frequencies to those used for voice and data. There are three main standards: DVBH, favoured in Europe; DMB, which has been adopted in South Korea and Japan; and MediaFLO, which is being rolled out in America. Watching TV using any of these technologies requires a TV capable handset, of course.In contrast, watching downloaded TV programmes on an iPod or other portable video player is already possible today. And unlike a programme streamed over 3G or broadcast via a dedicated mobile TV network, shows stored on an iPod can be watched on an underground train or inregions with patchy network coverage. That suggests that some shows better suit the download model, while others are better suited to real time transmission. The two approaches will probably coexist.Just as there are several competing mobile TV technologies, there are also many possible business models. Mobile operators might choose to build their own mobile TV broadcast networks; or they could form a consortium and build a shared network; or existing broadcasters could build such networks.The big question is whether the broadcasters and mobile operators can agree how to divide the spoils, assuming there are any. Broadcasters own the content, but mobile operators generally control the handsets, and they do not always see eye to eye. In South Korea, a consortium of broadcasters launched a free to air DMB network last month, but the country’s mobile operators were reluctant to provide their users with handsets able to receive the broadcasts, since they were unwilling to undermine the prospects for their own subscription based mobile TV services.Then there is the question of who will fund the production of mobile TV content: broadcasters, operators or advertisers? Again, the answer is probably all of the above .。

2018年可锐考研英语阅读真题范文（九）Senate inquiry in loan case is studying stock transferAn Education Department official and financial aid directors at three universities received stock in a student loan company from the company s current president in what may have been a violation of securities law, Senate aides looking into the transactions say.In various documents that have been turned over to staff members working for Senator Edward M. Kennedy, the president of the company described the transfers as gifts. But at least one recipient of the shares has said he paid for the stock.Because the executive, Fabrizio Balestri of Student Loan Xpress, had acquired the shares in a private placement of stock that restricts how it can be transferred, the gifts-or sale-may have run afoul of federal securities laws, said Mr. Kennedy, the Massachusetts Democrat who heads the Senate education committee. Yesterday he called on federal regulators to investigate the transactions.The senator s staff has been investigating relations between loan companies and universities. The disclosures last week that the financial aid administrators owned the stock have prompted concerns that they had an incentive to steer students to the loan company. The government official helped oversee lenders in the federal student loan program.The documents describing the transfers of stock as gifts were signed by Mr. Balestri and his wife. They contradict what one financial aid director said in an interview last week. That official, Lawrence Burt of the University of Texas at Austin, said he had paid $1,000 for 1,500 shares. Mr. Burt could not be reached for comment last night.Mr. Balestri transferred stock not only to Mr. Burt but also to David Charlow, financial aid director for Columbia s undergraduate college and its engineering school; Catherine Thomas, director of financial aid at the University of Southern California; and Matteo Fontana, general manager in a unit of the Office of Federal Student Aid at the Department of Education. In recent days, all four have been put on leave by their employers.Senate aides said that for each $10,000 in the private placement, investors had received 10,000 shares and 5,000 warrants, or options to purchase additional stock before a certain date, in Education Lending Group, which was then the parent of Student Loan Xpress. Mr. Balestri obtained $80,000 worth of stock and kept none of it, according to the documents. In a personal list called memorandums of gift , he wrote that he gave away 80,000 shares to 16 people on Dec. 31, 2001. That was one day before he began work at the company as its president.The 2001 private placement raised $3.7 million for Education Lending and was authorized by that company s chief executive, Robert deRose. At the time, the stock was trading between $1 and $2 a share. It is not clear who purchased the rest of the shares or whether anyone else at thecompany had knowledge of Mr. Balestri s transfers.violationn.违反, 违背, 妨碍, 侵害, [体]违例afoula.冲撞的，纠缠的ad.冲突着, 碰撞着securities law证券法steerv.驾驶，掌舵[真题例句] Much of the language used to describe monetary policy, such as steering the economy to a soft landing or a touch on the brakes , makes it sound like a precise science.[1997年阅读5][例句精译] 很多用来描述货币政策的词，如引导经济软着陆、经济刹车，使货币政策听起来像是一门精确的科学。

After the binge of the holidays, many stumble intoJanuary with a hangover, some fragile resolutionsand a desire to shed a few pounds. Alas, few willbenefit from rigid calorie-counting orcabbage-soup slurping. In a recent study of 31 long-term diet plans, the AmericanPsychological Association found that up to two-thirds of participants ended up heavier thanbefore they started. Some diets are more sensible than others, but any regimen thatpromises swift and dramatic results will doom most followers to failure. Weight-loss pillsand surgery are similarly ineffective—and sometimes dangerous—over time. Yetgirth-management is big business, full of charismatic hucksters and fake science, earning $40 billion a year in America alone.在假日的狂欢之后，许多人宿醉，下着不坚定的决心，立志要减去数磅体重，在跌跌撞撞中进入了一月。

2018年可锐考研英语阅读理解精选（五）Text5The haunting paintings of Helene Schjerfbeck, on show in the final leg of a travelling tour that has already attracted thousands of visitors in Hamburg and The Hague, may come as a surprise to many. Few outside the Nordic world would recognise the work of this Finnish artist who died in 1946. More people should. The 120 works have at their core 20 self-portraits, half the number she painted in all. The first, dated 1880, is of a wide-eyed teenager eager to absorb everything. The last is a sighting of the artist’s ghost-to-be; Schjerfbeck died the year after it was made. Together this series is among the most moving and accomplished autobiographies-in-paint.Precociously gifted, Schjerfbeck was 11 when she entered the Finnish Art Society’s drawing school. "The Wounded Warrior in the Snow", a history painting, was bought by a private collector and won her a state travel grant when she was 17. Schjerfbeck studied in Paris, went on to Pont-Aven, Brittany, where she painted for a year, then to Tuscany, Cornwall and St Petersburg. During her 1887 visit to St Ives, Cornwall, Schjerfbeck painted "The Convalescent". A child wrapped in a blanket sits propped up in a large wicker chair, toying with a sprig. The picture won a bronze medal at the 1889 Paris World Fair and was bought by the Finnish Art Society. To a modern eye it seems almost sentimental and is redeemed only by the somewhat stunned, melancholy expression on the child’s face, which may have been inspired by Schjerfbeck’s early experiences. At four, she fell down a flight of steps and never fully recovered.In 1890, Schjerfbeck settled in Finland. Teaching exhausted her, she did not like the work of other local painters, and she was further isolated when she took on the care of her mother . "If I allow myself the freedom to live a secluded life", she wrote, "then it is because it has to be that way." In 1902, Schjerfbeck and her mother settled in the small, industrial town of Hyvinkaa, 50 kilometres north of Helsinki. Isolation had one desired effect for it was there that Schjerfbeck became a modern painter. She produced still lives and landscapes but above all moody yet incisive portraits of her mother, local school girls, women workers in town . And of course she painted herself. Comparisons have been made with James McNeill Whistler and Edvard Munch. But from 1905, her pictures became pure Schjerfbeck."I have always searched for the dense depths of the soul, that have not yet discovered themselves", she wrote, "where everything is still unconscious-there one can make the greatest discoveries." She experimented with different kinds of underpainting, scraped and rubbed, made bright rosy red spots; doing whatever had to be done to capture the subconscious-her own and that of her models. In 1913, Schjerfbeck was rediscovered by an art dealer and journalist, Gosta Stenman. Once again she was a success. Retrospectives, touring exhibitions and a biography followed, yet Schjerfbeck remained little known outside Scandinavia. That may have had something to do with her indifference to her renown. "I am nothing, absolutely nothing", shewrote. "All I want to do is paint". Schjerfbeck was possessed of a unique vision, and it is time the world recognised that.1.
