单选题"The Heart of the Matter", the just-released report by the American Academy of Arts and Sciences (AAAS), deserves praise for affirming the importance of the humanities, and social sciences to the prosperity and security of liberal democracy in America. Regrettably, however, the report's failure to address the true nature of the crisis facing liberal education may cause more harm than good. In 2010, leading congressional Democrats and Republicans sent letters to the AAAS asking that it identify actions that could be taken by "federal, state and local governments, universities, foundations, educators, individual benefactors and others" to "maintain national excellence in humanities and social scientific scholarship and education. " In response, the American Academy formed the Commission on the Humanities and Social Sciences. Among the commission's 51 members are top-tier-university presidents, scholars, lawyers, judges, and business executives, as well as prominent figures from diplomacy, filmmaking, music and journalism. The goals identified in the report are generally admirable. Because representative government presupposes an informed citizenry, the report supports full literacy; stresses the study of history and government, particularly American history and American government; and encourages the use of new digital technologies. To encourage innovation and competition, the report calls for increased investment in research, the crafting of coherent curricula that improve students' ability to solve problems and communicate effectively in the 21st century, increased funding for teachers and the encouragement of scholars to bring their learning to bear on the great challenges of the day. The report also advocates greater study of foreign languages, international affairs and the expansion of study abroad programs. Unfortunately, despite the report are general "The Heart of the Matter" never gets to the heart of the matter: the illiberal nature of liberal education at our leading colleges and universities. The commission ignores that for several decades America's colleges and universities have produced graduates who don' t know the content and character of liberal education and are thus deprived of its benefits. Sadly, the spirit of inquiry once at home on campus has been replaced by the use of the humanities and social sciences as vehicles for publicizing "progressive", or left-liberal propaganda. Today, professors routinely treat the progressive interpretation of history and progressive public policy as the proper subject of study while portraying conservative or classical liberal ideas—such as free markets and self-reliance—as falling outside the boundaries of routine, and sometimes legitimate, intellectual investigation. The MAS displays great enthusiasm for liberal education. Yet its report may well set back reform by obscuring the depth and breadth of the challenge that Congress asked it to illuminate.

单选题Here is a familiar version of the boy-meets-girl situation. A young man has at last plucked up courage to invite a dazzling young lady out to dinner. She has accepted his invitation and he is overjoyed. He is determined to take her to the best restaurant in town, even if it means that he will have to live on memories and hopes during the month to come. When they get to the restaurant, he discovers that this ethereal creature is on a diet. She mustn't eat this and she mustn't eat that. Oh, but of course, she doesn't want to spoil his enjoyment. Let him by all means eat as much fattening food as he wants: it's the surest way to an early grave. They spend a truly memorable evening together and never see each other again. What a miserable lot dieters are! You can always recognize them from the sour expression on their faces. They spend most of their time turning their noses up at food. They are forever consulting calorie charts; gazing at themselves in mirrors; and leaping on to weighing-machines in the bathroom. They spend a lifetime fighting a losing battle against spreading hips, protruding tummies and double chins. Some wage all-out war on FAT. Mere dieting is not enough. They exhaust themselves doing exercises, sweating in sauna baths, being pummeled and massaged by weird machines. The really wealthy diet-mongers pay vast sums for "health cures". For two weeks they can enter a nature clinic and be starved to death for a hundred guineas a week. Don't think it' s only the middle-aged who go in for these fads either. Many of these bright young things you see are suffering from chronic malnutrition: they are living on nothing but air, water and the goodwill of God. Dieters undertake to starve themselves of their own free will; so why are they so miserable? Well, for one thing, they're always hungry. You can't be hungry and happy at the same time. All the horrible concoctions they eat instead of food leave them permanently dissatisfied. Wonderfood is a complete food, the advertisement says. Just dissolve a teaspoonful in water. A complete food it may be, but not quite as complete as a juicy steak. And, of course, they're always miserable because they feel so guilty. Hunger just proves too much for them and in the end they lash out and devour five huge guilt-inducing cream cakes at a sitting. And who can blame them? At least three times a day they are exposed to temptation. What utter torture it is always watching others tucking into piles of mouth-watering food while you munch a water biscuit and sip unsweetened lemon juice! What's all this self-inflicted torture for? Saintly people deprive themselves of food to attain a state of grace. Unsaintly people do so to attain a state of misery. It will be a great day when all the dieters in the world abandon their slimming courses; when they hold out their plates and demand second helpings!

单选题Some problems can be readily identified simply by looking around. These problems concern the pollution of our environment by technology as a result of sudden upsets in the physical, economic and social balance. The most obvious of these are the general pollution of our physical environment and the destruction of irreplaceable natural resources. Not so obvious as these, but just as painfully significant to some, are the disappearing and changing of jobs which overnight often create large groups of jobless citizens. Can technology be used to undo what it has done, replace what it has destroyed or substitute for what it has caused to disappear? No one knows. Many wonder whether or not all of the sources of pollution have yet been identified, whether or not they are being arrested and whether or not they will be prevented from recurring. Another set of problems relates to what technological advancement has done to the quality of life. An improved social life has not been unfortunately, either the goal or the chief beneficiary of technological change. Rather, any improvements that have occurred have been more accidental than intended. Too much has happened too fast. The changes demanded of marriage and family relationships remain largely unexamined. It is often a matter of "put up or shut up", and a person has to adapt his lifestyle to ever-changing conditions with little time for choice. The "no-move-no-advancement" type is an example of one such problem. Many people are coming to think that the reward is simply not worthy of the struggle, and they are taking jobs with less responsibility and lower pay.

单选题Confronted with patient facing death, physicians may feel a sense of medical impotence and failure. Years of training and zeal to heal have focused on doing anything and everything to save the patient. Death is treated as the enemy. One might ask, "What use can I be if I cannot fix?" One may be tempted to withdraw. There may be no meaningful closure with a patient other than referral to home care or hospice. Feelings evoked by a patient"s dying are also antithetical(对立的)to the original "call" to medicine—the desire to make a difference in people" s lives and the alleviation of pain and suffering. Over time these inner directives may have been obscured by the rigors of a pressured practice, not to mention the climate of malpractice litigation(诉讼). This threat necessitates obsessive attention to the details of intervention options, possibly at the cost of considering the needs of the whole person at hand. So the moment when death raises its specter(恐惧)is a crossroads. Herein lies the opportunity for physicians to go beyond their conventional model of relating to patients. This is when the conventional therapeutic tools can be set aside in favor of the most powerful contribution of all: the physician " s caring itself. The only requirement is a willingness to extend conscious listening and basic humanity to the dying patient. The simple act of visitation, of presence, of taking the trouble to witness the patient"s process can be in itself a potent healing affirmation—a sacramental(圣礼的)gesture received by the dying person who may be feeling helpless, diminished, and fearful that they have little to offer others. The patient may also fear that he or she has failed. How meaningful it is to be told by my physicians that they are learning from me! I feel honored and joined by my physicians as we participate in these human, vulnerable, and mysterious moments at the end of my life. I and many dying persons would agree that beyond pain control, the three elements we most need are feeling cared about, being respected, and enjoining a sense of continuity, be it in relationships or in terms of spiritual awareness.

单选题Among all the malignancies, lung cancer is the biggest killer; more than 100 000 Americans die of the disease. Giving up smoking is one of obvious ways to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by eating a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene. The finding, published in THE LANCET, is part of a long-range investigation of diet and disease. Since 1957, some American researchers have monitored the dietary habits and medical histories of 2 000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shekelle of St. Luke's Medical Center, the researchers recently began to sort out the links between the subjects' dietary patterns and cancer. Other studies of animals and humans have suggested that vitamin A offer some protection against lung cancer. The correlation seemed logical, explains Shekelle, since vitamin A is essential for the growth of the epithelial tissue that lines the airways of the lungs. Vegetables: But the earlier research did not distinguish between the two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver and dairy products like milk, cheese, butter and eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables and fruits, including carrots, spinach, squash, tomatoes, sweet potatoes and apples. In the study, Shekelle and his colleagues found little correlation between the incidence of lung cancer and the consumption of foods containing preformed vitamin A. But when they examined the data on carotene intake, they discovered a significant relationship. Among the 488 men who had the lowest level of carotene consumption, there were 14 cases of lung cancer, in a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even for long-time smokers—but to a lesser degree. Further studies will be necessary before the link between lung cancer and carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balanced diet that includes goods rich in carotene. For a smoker, a half-cup of carrots every day might possibly make the difference between life and death.

单选题If you are reading this article, antibiotics have probably saved your life—and not once but several times. A rotten tooth, a knee operation, a brush with pneumonia; any number of minor infections that never turned nasty. You may not remember taking the pills, so unremarkable have these one-time wonder drugs become. Modern medicine relies on antibiotics — not just to cure diseases, but to augment the success of surgery, childbirth and cancer treatments. Yet now health authorities are warning, in uncharacteristically apocalyptic terms, that the era of antibiotics is about to end. In some ways, bacteria are continually evolving to resist the drugs. But in the past we've always developed new ones that killed them again. Not this time. Infections that once succumbed to everyday antibiotics now require last-resort drugs with unpleasant side effects. Others have become so difficult to treat that they kill some 25, 000 Europeans yearly. And some bacteria now resist every known antibiotic. Regular readers will know why: New Scientist has reported warnings about this for years. We have misused antibiotics appallingly, handing them out to humans like medicinal candy and feeding them to livestock by the tonne, mostly not for health reasons but to make meat cheaper. Now antibiotic-resistant bacteria can be found all over the world — not just in medical facilities, but everywhere from muddy puddles in India to the snows of Antarctica (南极洲) . How did we reach this point without viable successors to today's increasingly ineffectual drugs? The answer lies not in evolution but economics. Over the past 20 years, nearly every major pharmaceutical company has abandoned antibiotics. Companies must make money, and there isn't much in short-term drugs that should be used sparingly. So researchers have discovered promising candidates, but can't reach into the deep pockets needed to develop them. This can be fixed. As we report this week, regulatory agencies, worried medical bodies and Big Pharma are finally hatching ways to remedy this market failure. Delinking profits from the volume of drug sold (by adjusting patent rights, say, or offering prizes for innovation) has worked for other drugs, and should work for antibiotics — although there may be a worryingly long wait before they reach the market. One day, though, these will fall to resistance too. Ultimately, we need, evolution-proof cures for bacterial infection: treatments that stop bacteria from causing disease, but don't otherwise inconvenience the little blighters. When resisting drugs confers no selective advantage, drugs will stop breeding resistance. Researchers have a couple of candidates for such treatment. But they fear regulators will drag their feet over such radical approaches. That, too, can be fixed. We must not neglect development of the sustainable medicine we need, the way we have neglected simple antibiotic R&D. If we do, one day another top doctor will be telling us that the drugs no longer work—and there really will be no help on the way.

单选题Most people would be impressed by the high quality of medicine available to most Americans. There is a lot of specialization, a great deal of attention to the individual, a vast amount of advanced technical equipment, and intense effort not to make mistakes because of the financial risk which doctors and hospitals must face in the courts if they handle things badly. But the Americans are in a mess. The problem is the way in which health care is organized and financed. Contrary to public belief, it is not just a free competition system. To the private system has been joined a large public system, because private care was simply not looking after the less fortunate and the elderly. But even with this huge public part of the system, which this year will eat up 84. 5 billion dollars— more than 10 percent of the U. S. budget—large numbers of Americans are left out. These include about half the 11 million unemployed and those who fail to meet the strict limits on income fixed by a government trying to make savings where it can. The basic problem, however, is that there is no central control over the health system. There is no limit to what doctors and hospitals charge for their services. Other than what the public is able to pay. The number of doctors has shot up and prices have climbed. When faced with toothache, a sick child, or a heart attack, all the unfortunate person concerned can do is pay up. Two-thirds of the population are covered by medical insurance. Doctors charge as much as they want knowing that the insurance company will pay the bill. The medical profession has as a result become America's new big businessmen. The average income of doctors has now reached $100, 000 a year. With such vast incomes the talk in the doctor's surgery is as likely to be about the doctor's latest financial deal, as about whether the minor operation he is recommending at several thousand dollars is entirely necessary. The rising cost of medicine in the U. S. A. is among the most worrying problem facing the country. In 1981 the country's health cost climbed 15. 9 percent—about twice as fast as prices in general.

单选题The great question that this paper will, but feebly, attempt to answer is, what is the creative process? Though much theory has accumulated, little is really known about the power that lies at the bottom of poetic creation. It is true that great poets and artists produce beauty by employing all the powers of personality and by fusing emotions, reason, and intuitions. But what is the magical synthesis that joins and arranges these complex parts into poetic unity? John L. Lowes, in his justly famous "The Road to Xanadu", developed one of the earliest and still generally acceptable answers to this tantalizing question. Imaginative creation, he concludes, is a complex process in which the conscious and unconscious minds jointly operate. "There is... the Deep Well with its chaos of fortuitously blending images; but there is likewise the Vision which sees shining in and through the chaos of the potential lines of Form, and with the Vision, the controlling Will, which gives to that potential beauty actuality." The Deep Well is the unconscious mind that is peopled with the facts, ideas, and feelings of the conscious activity. The imaginative vision, an unconscious activity, shines through the land of chaos, of lights and shadows, silently seeking pattern and form. Finally, the conscious mind again, through Will, captures and embodies the idea in the final work of art. In this way is unity born out of chaos. Though there can be no absolute certainty, there is general agreement that the periods in the development of a creative work parallel, to some extent, Lowes" theory of Well, Vision, Form, and Will. There are at least three stages in the creative process: preparation, inspiration, work. In a sense, the period of preparation is all of the writer"s life. It is the Deep Well. It is especially a period of concentration which gives the unconscious mind an opportunity to communicate with the conscious mind. When remembrances of things past reach the conscious level of the writer"s mind, he is ready to go on with the process. Part of this preparation involves learning a medium — learning a language, learning how to write, learning literary forms. It is important to mot here that form cannot be imposed upon the idea. Evidence, though sparse, shows that the idea gives birth to the form that can best convey it. It is the Vision, according to Lowes, which sees shining in and through the chaws of the potential lines of Form..."

单选题In a sense, the new protectionism is not protectionism at all, at least not in the traditional sense of the term. The old protectionism referred only to trade restricting and trade expanding devices, such as the tariff or export subsidy. The new protectionism is much broader than this: it includes interventions into foreign trade but is not limited to them. The new protectionism, in fact, refers to how the whole of government intervention into the private economy affects international trade. The emphasis on trade is still there, thus came the term "protection". But what is new is the realization that virtually all government activities can affect international economic relations. The emergence of the new protectionism in the Western world reflects the victory of the interventionist, or welfare economy over the market economy. Jab Tumiler writes, "The old protectionism...coexisted, without any apparent intellectual difficulty with the acceptance of the market as a national as well as an international economic distribution mechanism — indeed, protectionists as well as(if not more than)free traders stood for laissez faire(放任政策). Now, as in the 1930s, protectionism is an expression of a profound skepticism as to the ability of the market to distribute resources and incomes to societies satisfaction." It is precisely this profound skepticism of the market economy that is responsible for the protectionism. In a market economy, economic change of various colors implies redistribution of resources and incomes. The same opinion in many communities apparently is that such redistributions often are not proper. Therefore, the government intervenes to bring about a more desired result. The victory of the welfare state is almost complete in northern Europe. In Sweden, Norway, Finland, Denmark, and the Netherlands, government intervention in almost all aspects of economic and social life is considered normal. In Great Britain this is only somewhat less true. Government traditionally has played a very active role in economic life in France and continued to do so. Only West Germany dares to go against the tide towards excessive interventionism in Western Europe. It also happens to be the most successful Western European economy. The welfare state has made significant progress in the United States as well as in Western Europe. Social security, unemployment insurance, minimum wage laws, and rent control are by now traditional welfare state elements on the American scene.

单选题On a five to three vote, the Supreme Court knocked out much of Arizona's immigration law Monday— a modest policy victory for the Obama Administration. But on the more important matter of the Constitution, the decision was an 8-0 defeat for the Administration' s effort to upset the balance of power between the federal government and the states. In Arizona vs. United States, the majority overturned three of the four contested provisions of Arizona's controversial plan to have state and local police enforce federal immigration law. The Constitutional principles that Washington alone has the power to "establish a uniform Rule of Naturalization " and that federal laws precede state laws are noncontroversial. Arizona had attempted to fashion state policies that ran parallel to the existing federal ones. Justice Anthony Kennedy, joined by Chief Justice John Roberts and the Court' s liberals, ruled that the state flew too close to the federal sun. On the overturned provisions the majority held the congress (国会) had deliberately "occupied the field" and Arizona had thus intruded on the federal' s privileged powers. However, the Justices said that Arizona police would be allowed to verify the legal status of people who come in contact with law enforcement. That's because Congress has always envisioned joint federal-state immigration enforcement and explicitly encourages state officers to share information and cooperate with federal colleagues. Two of the three objecting Justice—Samuel Alito and Clarence Thomas—agreed with this Constitutional logic but disagreed about which Arizona rules conflicted with the federal statute. The only major objection came from Justice Anton Scalia, who offered an even more robust defense of state privileges going back to the Alien and Sedition Acts. The 8-0 objection to President Obama turns on what Justice Samuel Alito describes in his objection as " a shocking assertion of federal executive power". The White House argued that Arizona' s laws conflicted with its enforcement priorities, even if state laws complied with federal statutes to the letter. In effect, the White House claimed that it could invalidate any otherwise legitimate state law that it disagrees with. Some powers do belong exclusively (专门地)to the federal government, and control of citizenship and the borders is among them. But if Congress wanted to prevent states from using their own resources to check immigration status, it could. It never did so. The administration was in essence asserting that because it didn't want to carry out Congress's immigration wishes, no state should be allowed to do so either. Every Justice rightly rejected this remarkable claim.

单选题Stone tools, animal bones and an incised mammoth tusk found in Russia"s frigid far north have provided what archaeologists say is the first evidence that modern humans or Neanderthals lived in the Arctic more than 30,000 years ago, at least 15,000 years earlier than previously thought. A team of Russian and Norwegian archaeologists, describing the discovery in today"s issue of the journal Nature, said the campsite, at Mamontovaya Kurya, on the Ura River at the Arctic Circle, was the "oldest documented evidence for human presence at this high latitude." Digging in the bed of an old river channel close to the Ural Mountains, the team uncovered 123 mammal bones, including horse, reindeer and wolf. "The most important find," they said, was a four-foot mammoth tusk with grooves made by chopping with a sharp stone edge, "unequivocally the work of humans." The tusk was carbon-dated at about 36,600 years old. Plant remains found among the artifacts were dated at 30,000 to 31,000 years. Other archaeologists said the analysis appeared to be sound. But they cautioned that it was difficult, when dealing with riverbed deposits, to be sure that artifacts had not become jumbled out of their true place, and thus time, in the geologic layers. They questioned whether the discoverers could reliably conclude that the stone tools were in fact contemporary with the bones. But in a commentary accompanying the article, Dr. John A. J. Gowlett of the University of Liverpool in England wrote, "Although there are questions to be answered, the artifacts illustrate both the capacity of early humans to do the unexpected, and the value of archaeologists" researching in unlikely areas." The discoverers said they could not determine from the few stone artifacts whether the site was occupied by Neanderthals, hominids who by then had a long history as hunters in Europe and western Asia, or some of the first anatomically modern humans to reach Europe. In any case, other archaeologists said, the findings could be significant. If these toolmakers were Neanderthals, the findings suggested that these human relatives, who became extinct after 30,000 years ago, were more capable and adaptable than they are generally given credit for. Living in the Arctic climate presumably required higher levels of technology and social organization. If they were modern humans, then the surprise is that they had penetrated so far north in such a short time. There has been no firm evidence for modern humans in Europe before about 35,000 years ago. It had generally been thought that the northernmost part of Eurasia was not occupied by humans until the final stage of the last ice age, some 13,000 to 14,000 years ago, when the world"s climate began to moderate. Dr. Gowlett said the new findings indicated that the Arctic region of European Russia was extremely cold but relatively dry and ice-free more than 30,000 years ago.

单选题The alarm on our household computer terminal rings and wakes me up. My husband simply stirs and goes back to sleep. I transfer today" s information onto the personal data card I carry with me everywhere and scan today" s readings. Values are given as to the number of liters of water I can use, the amount of coal-generated electricity I have allocated and how many "envirocredits" I have earned. I am free to use the water and electricity as I chose, however I notice that the ration of electricity is decreasing everyday. Of course, this will not be a problem when we have earned enough envirocredits to buy another solar panel. Envirocredits are earned by buying goods with limited or no packaging, minimizing the amount of garbage thrown out, by financially supporting " environtechn-ology". Before cars were phased out due to unpopularity, credits could be gained by using public transport. I notice an extra passage added to the readings. At last I have been given permission to have a child. Almost instantaneously a package arrives with a label on it; "Anti-sterilization Unit". Inside there are instructions and a small device that looks like a cross between a pistol and a syringe. Eagerly I follow the instructions. The procedure is painless and I don" t know if I am imagining it but I seem to feel the effects at once. Shaken my husband awake, I tell him the good news. I want to get started baby-making right now. " You" ve been on the waiting list for 37 years," he says. " Can" t you wait until I" ve woken up properly?" I decide that I probably don" t have much choice and wander downstairs. I am feeling very privileged to have the opportunity to create a new life. It is saddening, however, when I realize that, because of strict population controls, this new life will be replacing an old one. I decide to ring my mother and tell her the good news. When she answers the phone she is crying. She has received word that my grandmother has failed her latest health check and will be euthanized next week. For some reason, I don"t feel like creating that new life anymore.

单选题On June 26, 2000, two scientific teams announce at the White House that they had deciphered virtually the entire human genome, a prodigious feat that involved determining the exact sequence of chemical units in human genetic material. An enthusiastic President Clinton predicted a revolution in "the diagnosis, prevention and treatment of most, if not all, human diseases". Now, 10 years later, a sobering realization has set in. Decoding the genome has led to stunning advances in scientific knowledge and DNA-processing technologies but it has done relatively little to improve medical treatments or human health. To be fair, many scientists at the time were warning that it would be a long, slow slog to reap clinical benefits. And there have been some important advances, such as powerful new drugs for a few cancers and genetic tests that can predict whether people with breast cancer need chemotherapy. But the original hope that close study of the genome would identify mutations or variants that cause diseases like cancer, Alzheimer's and heart ailments—and generate treatments for them—has given way to realization that the causes of most diseases are enormously complex and not easily traced to a simple mutation or two. In the long run, it seems likely that the genomic revolution will pay off. But no one can be sure. Even if the genetic roots of some major diseases are identified, there is no guarantee that treatments can be found. The task facing science and industry in the coming decades is at least as challenging as the original deciphering of the human genome.

单选题Folk wisdom holds that the blind can hear better than people with sight. Scientists have a new reason to believe it. Research now indicates that blind and sighted people display the same skill at locating a sound" s origin when using both ears, but some blind people can home in on sounds more accurately than their sighted counterparts when all have one ear blocked. Canadian scientists described the work in the Sept. 17 NATURE. Participants in the study were tested individually in a sound-insulated room. They faced 16 small, concealed loudspeakers arrayed in a semicircle a few feet away. With a headrest keeping their heads steady, the participants pointed to the perceived origins of the sounds. The researchers tested eight blind people, who had been completely sightless from birth or since a very early age. They also tested three nearly blind persons, who had some residual vision at the periphery of their gaze; seven sighted people wearing blindfolds; and 29 sighted people without blindfolds. All participants were tested beforehand to ensure that their hearing was normal. When restricted to one-ear, or monaural, listening, four of the eight blind people identified sound sources more accurately than did the sighted people, says study co-author Michel Pare, a neuroscientist at the University of Montreal. The sighted people showed especially poor localization of sounds from the speakers on the side of blocked ear. In sighted people who can hear with both ears, " the brain learns to rely on binaural [ stereo ] cues. These data suggest that blind people haven" t learned that and keep monaural cues as the dominant cues," says Enc I. Knudsen, a neurobiologist at Stanford University School of Medicine, "I find it surprising. "

单选题Any scientist who is not a hypocrite will admit the important part that luck plays in scientific discovery. Our estimate of the importance of luck is inherently biased: we know when we benefit from luck, but in the nature of things cannot assess how often bad luck deprives us of the chance of making what might have been an important discovery. A colleague and I carried out an experiment in which little tissue fragments, which were very difficult to work with, were injected into mice of different strains. If we had been more experienced, we would have injected only white blood cells (which would have been easier to handle) into the mice. We now know that if we had done this, we would not have discovered actively acquired tolerance because the grafts would have in effect rejected their hosts. Obviously, we were lucky, but our scientific training enabled us to recognize the significance of the accident. I think, therefore, that there was no need for the distinguished neu-rophysiologist Hodgkin to refer to his "feeling of guilt about suppressing the part which chance and good fortune played in what now seems to be a rather logical development." It might nevertheless seem as if luck plays a dominant role in scientific discovery. I would like to challenge this view for the following reasons; we sometimes describe as "lucky" a person who wins a prize in a lottery at long odds; but if we describe the accidental discovery on a park bench of a lottery ticket that turns out to be the winning one? The two cases are quite different. A person who buys a lottery ticket is putting himself or herself in the way of winning a prize. This individual has, so to speak, purchased candidacy for such a turn of events and all the rest is a matter of mathematical probabilities. So it is with scientists. A scientist is anyone who, by observations and experiments conducted, by the literature read, and even by the company kept, puts himself or herself in the way of making a discovery. These individuals, by deliberate action, have enormously enlarged their awareness—their candidacy for good fortune—and will not take into account evidence of a kind that a beginner or a casual observer would probably overlook or misinterpret. I honestly do not think that blind luck of the kind enjoyed by someone who finds a winning lottery ticket for which he or she has not paid plays an important part in science or that many important discoveries arise from the casual intersection of two lines. Nearly all successful scientists have emphasized the importance of preparedness of mind, and I want to emphasize that this preparedness of mind is worked for and paid for by a great deal of exertion and reflection. If these exertions lead to a discovery, then I think it would be inappropriate to credit such a discovery to luck.

单选题It seems intuitive that going to a specialist physician will result in more thorough and up-to-date care for whatever ails you. In fact many studies support this idea — but health-care researchers caution that they may not tell the whole story. The first question is whose patients are sicker? Specialists tend to treat more complicated forms of disease but generalists — family physicians and general practitioners — are more likely to treat patients with several coexisting diseases. A second question is what counts as the most valuable treatment? Specialists are more familiar with standards of care for the diseases they treat regularly, says Harlan M. Krumholz of Yale University. On the other hand, a generalist may do a better job of coordinating a patient"s care and keeping an eye on a person"s overall health, says Martin T. Domohoe of the Oregon Health Sciences University in Portland. To further complicate comparisons many generalists will consult with specialists on complicated cases but medical records do not always show that, says Carolyn Clancy of the Agency for Health Care Policy and Research in Rockville, Md. That said stroke patients treated by neurologists are more likely to survive than stroke patients treated by generalists. Among about 38,000 stroke sufferers nationwide, 16.1% of those treated by a neurologists died within 3 months compared with 25.3 percent of those treated by family physicians. Several studies have shown that people with heart disease fare better when they are treated by cardiologists, says S. Nash of the Mount Sinai Medical Center in New York. But it"s hard to figure out exactly why. "Physician specialty, in addition to being a measure of formal training in the field, is also a proxy for clinical experience." he says, "It"s very difficult to separate out the overlapping concepts. One, that practice makes perfect; two, the effect of the educational and time investments in a clinical problem the physician is simply interested in; and three, the issue of formal training." Differences between specialist care and generalist care, however. Pale in comparison with the finding that both specialists and generalists often fail to put the latest knowledge into practice, contend both Donohoe and Clancy. A report by the US General Accounting Office documented that heart attack survivors who saw cardiologists regularly were more likely to take cholesterol-lowering drugs and beta blockers which reduce heart rate and blood pressure than those who received care from a generalist. Even so, these life-prolonging drugs were not prescribed to many patients who appeared to be eligible for them, implying that both generalists and specialists could do better. "Maybe we are focusing too much energy on the differences between generalist and specialist care," says Donohoe. Perhaps, he adds, "We should focus more intently on improving the quality of communication between generalists and specialists and on developing and promoting practice guidelines that might have a much bigger effect on the overall health of Americans."

单选题When people are struck by lightening, they fall to the ground as though they were struck by a severe blow to the head. After the shock they may remain unconscious, become semiconscious or be conscious but confused and dazed, at least for a time. Flashes of light may continue passing before their eyes, and blindness and deafness may follow. The nervous system may be badly affected, causing paralysis, pain in the limbs and even hemorrhage. There will be burns where the lightening passed through the body, and like all electrical bunts, they are often deep and sever. All persons, especially campers and hunters, should know how to give first aid to someone who has been struck by lightening. Do not be afraid to touch the victim. You won't get a shock. The lightening has already been grounded. Remember that speed is of the greatest importance in severe cases. The first thing to do is to loosen tight clothing about the throat and waist. Then clear the air passages of mucus (黏液) if present, and apply artificial respiration if necessary. Give mouth-mouth resuscitation if needed, or give oxygen if available. Many victims thought to be dead have been revived after treatment. Send someone for a doctor as soon as possible, but don't leave the victim alone. If a doctor is not available, take the person to a hospital as soon as the person can be safely moved. Signs of shock are: pale, cold, sticky skin; weak, rapid pulse; shallow, irregular breathing or, in extreme cases, no breathing at all. To treat shock, you must keep the patient lying down with the head lower than the feet and cover him or her with a blanket but watch out for overheating. Giving a stimulating hot tea or coffee will help, but only if the patient is thoroughly conscious. After breathing has been restored and shock is treated, treat the burns. Apply some salve and cover them with a clean cloth or a sterile dressing. If conscious, the patient will be badly frightened, so do all you can to reassure. A little knowledge and a helping hand may save someone's life.

单选题During the past 30 years or so, health care has increasingly become a form of business. In addition, the environment surrounding health care has been greatly altered by the advent of more sophisticated medical technologies and increased specialization. It is no longer true to say that doctors regard their profession as a sacred calling, and while the doctor-patient relationship still remains, it is not the relationship based solely on trust which it used to be. Of course there are many doctors who have endeavored to increase the transparency of their behavior as medical professionals, and patients can receive effective treatment when such doctors work closely together and share notes. An example of such cooperation can be found in the field of remote health care, which has been introduced on an experimental basis in several regions. Since most medical specialists live in cities, patients who live in the country have to travel a long distance to consult a specialist. This is especially hard on the elderly, both financially and physically. Through a computer network, patients who live in the country can consult a medical specialist in the city, tell him their symptoms, and receive advice without the need for a journey to the specialist"s office. Also, with several doctors being assigned to a single patient, the transparency of each doctor"s behavior is further ensured. On the other hand, however, it is also true that remote health consultation is not generally regarded as a form of medical treatment. For any sort of consultation to be regarded as medical treatment, most people feel that the patient must actually visit the doctor, and undergo an examination by the doctor in person. Remote health care is essentially a means for doctors to work as a team. In order for this to be practicable, it is important to establish a system whereby financial support can be extended to a doctor who, as a member of a medical team, provides only information. Establishment of such a system will further advance the cause of" free access to information" in the health care field.
