单选题David Moore taught physics at the City School. He needed some expensive books, and so he bought them. He left them in his car in a quiet street. Then he bought other things at other shops. At six o'clock he came back to the car. One window was open—and the books were not there! David drove home to Fry Road. That night he wrote a letter to a newspaper. The next day he went to the police. On Friday people read this in the newspaper: BOOK: Have you any old books? I buy old and modern books. Open all day on Saturdays. David Moore, 26 Fry Road. David stayed at home on Saturday. His first visitor came at eight o'clock. David took him to the kitchen. At half past nine another man arrived. He had a bag under his arm. "Mr. Moore?" the man asked. "That's right. "David said. "Can I help you?" "I've got some good book. You buy books, don't you?" "Yes. Bring them in. I'll have a look at them. " Soon the books were on the dining-table. "Come in now," David called," and bring the list. " A policeman came into the dining-room. He read the names on the list in his hand. They were the same. "Come with me , sir , "the policeman said to the man.

单选题 Question 11-15 Without regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify moods and actions, our inclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help to determine the development of bodily form and may even determine an individual's behavioral capacities. Later in life the changing outputs of some endocrine glands and the body's changing sensitivity to some hormones are essential aspects of the phenomena of aging. Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergence of endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substance is secreted from cells in the intestinal walls when food enters the stomach; it travels through the bloodstream and stimulates the pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secrete chemical agents that are conveyed by the bloodstream and regulate distant target organs or tissues. Bayliss and Starling demonstrated that chemical integration could occur without participation of the nervous system. The term "hormone" was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning "to excite or set in motion". The term "endocrine" was introduced shortly thereafter. "Endocrine" is used to refer to glands that secrete products into the bloodstream. The term "endocrine" contrasts with "exocrine", which is applied to glands that secrete their products though ducts to the site of action. Examples of exocrine glands are the tear glands, the sweat glands, and the pancreas, which secrete pancreatic juice through a duct into the intestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless glands.

单选题In 1948, Seattle authorities feared that a race riot would break out in a run-down housing area. A thousand families—300 of them black—were jammed into temporary barracks built for war workers. Tension was in the air, rumors rife, a stabbing reported. The University of Washington, called on for advice, rushed 25 trained interviewers to the scene. The interviewers went from door to door, trying to discover the extent of racial hatred. They were surprised to find very little. Ninety percent of the whites and blacks interviewed said that they felt "about the same" of "more friendly" toward the other group since moving into the area. What, then, was eating them? These families were angry about the ramshackle buildings, the back-firing kitchen stoves and the terrible roads inside the property. Many were worried about a strike at Boeing Airplane Co. In short, a series of frustrations from other causes had infected the whole community, and could have resulted in a race riot. This case is a dramatic application of a challenging theory about human behavior exhaustively demonstrated by a group of Yale scientists in an old book, Frustration and Aggression, which has become a classic. Since reading it some years ago, I have met many of my personal problems with better understanding, and gained fresh insight into some big public questions as well. A common result of being frustrated, the Yale investigator have shown, is an act of aggression, sometimes violent. To be alive is to have a goal and pursue it—anything from cleaning the house, or planning a vacation, to saving money for retirement. If someone or something blocks goal, we begin to feel pent up and thwarted. Then we get mad. The blocked goal, the sense of frustration, aggression action—this is the normal human sequence. If we are aware of what is going on inside us, however, we can save ourselves a good deal of needless pain and trouble. The aggressive act that frustration produces may take a number of forms. It may be turned inward against oneself, with suicide as the extreme example. It may hit back directly at the person or thing causing the frustration. Or it may be transferred to another object—what psychologists call displacement. Displacement can be directed against the dog, the parlor furniture, the family or even total strangers. The classic pattern of frustration and aggression is nowhere better demonstrated than in military life. GIs studied by the noted American sociologist Samuel A. Stouffer in the last war were found to be full of frustration due to their sudden loss of civilian liberty. They took it our verbally on the brass, often most unjustly. But in combat, soldiers felt far more friendly toward their officers. Why? Because they could "discharge their aggression directly against the enemy". Dr. Karl Menninger, of the famous Menninger Foundation at Topeka, pointed out that children in all societies are necessarily frustrated, practically from birth, as they are broken into the customs of the tribe. A baby"s first major decision is "whether to holier or smaller"—when it discovers that the two acts cannot be done simultaneously. Children have to be taught habits of cleanliness, toilet behavior, regular feeding, punctuality; habits that too often are hammered in. Grownups with low boiling points, said Dr. Menninger, probably got that way because of excessive frustration in childhood. We can make growing up a less difficult period by giving children more love and understanding. Parents in less "civilized" societies, Menninger observes, often do this. He quotes a Mohave Indian, discussing his small son. "Why should I strike him? He is small, I am big. He cannot hurt me." When we do experience frustration, there are several things we can do to channel off aggression. First, we can try to remove the cause which is blocking our goal. An individual may be able to change his foreman, even his job or his residence, if the frustration is a continuing one. If this cannot be done, then we can seek harmless displacements. Physical outlets are the most immediately helpful. Go out in the garden and dig like fury. Or take a long walk, punch a bag in the gym, make the pins fly in a bowling alley, cut down a tree. The late Richard C. Tolman, a great physicist, once told me that he continued tennis into his 60s because he followed it so helpful in working off aggressions. But perhaps the best way of all to displace aggressive feelings is by hard, useful work. If both body and mind can be engaged, so much the better.

单选题Questions 26-30 Taking charge of yourself involves putting to rest some very prevalent myths. At the top of the list is the notion that intelligence is measured by your ability to solve complex problems; to read, write and compute at certain levels; and to resolve abstract equations quickly. This vision of intelligence asserts formal education and bookish excellence as the true measures of self fulfillment. It encourages a kind of intellectual prejudice that has brought with it some discouraging results. We have come to believe that someone who has more educational merit badges, who is very good at some form of school discipline is "intelligent. " Yet mental hospitals are filled with patients who have all of the properly lettered certificates. A truer indicator of intelligence is an effective, happy life lived each day and each present moment of every day. If you are happy, if you live each moment for everything it"s worth, then you are an intelligent person. Problem solving is a useful help to your happiness, but if you know that given your inability to resolve a particular concern you can still choose happiness for yourself, or at a minimum refuse to choose unhappiness, then you are intelligent. You are intelligent because you have the ultimate weapon against the big N. B.D. --Nervous Break Down. "Intelligent" people do not have N. B. D. "s because they are in charge of themselves. They know how to choose happiness over depression, because they know how to deal with the problems of their lives. You can begin to think of yourself as truly intelligent on the basis of how you choose to feel in the face of trying circumstances. The life struggles are pretty much the same for each of us. Everyone who is involved with other human beings in any social context has similar difficulties. Disagreements, conflicts and compromises are a part of what it means to be human. Similarly, money, growing old, sickness, deaths, natural disasters and accidents are all events which present problems to virtually all human beings. But some people are able to make it, to avoid immobilizing depression and unhappiness despite such occurrences, while others collapse or have an N, B. D. Those who recognize problems as a human condition and don"t measure happiness by an absence of problems are the most intelligent kind of humans we know; also, the most rare.

单选题Questions 16-20 Science is a dominant theme in our culture. Since it touches almost every facet of our life, educated people, need at least some acquaintance with its structure and operation. They should also have an understanding of the subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist. This book is written for the intelligent student or lay person whose acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse of dried facts; for the person who sees the chief objective of science as the production of gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or--independently of any course--simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is. who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture. We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not a unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating him and her. This policy is far from being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating hail of the human race equally. We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn"t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earn a living.

单选题Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the drastic experiment of Frederick Ⅱ in the thirteenth century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent. All the infants died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected. Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed. Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like sounds; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1,000 words which he can put into sentences, and at four his language differs from that of his parents in style rather than grammar. Recent evidence suggests that an infant is born with the capacity to speak. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern "toy-bear". And even more incredible is the young brain's ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways. But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child's non-verbal signals is essential to the growth and development of language.

单选题 {{B}}Extract 1{{/B}} A stylish dining room with cream walls and curtains and black carpet as perfect foil to an eclectic array of furniture. Many of the pieces are classics of their particular era, and demonstrate how old and new designs can be happily mixed together. The prototype chair in the foreground has yet to prove its staying power and was thought up by the flat's occupant. He is pictured in his living room which has the same decorative theme and is linked to the dining room by a high Medieval-styled archway where was once a redundant and uninspiring fireplace. {{B}}Extract 2{{/B}} Old bathrooms often contain a great deal of ugly pipework in need of disguising. This can either be done by boxing in the exposed pipes, or by fitting wood paneling over them. As wood paneling can be secured over almost anything — including old ceramic tiles and chipped walls — is an effective way of disguising pipework as well as being an attractive form of decoration. The paneling can be vertical, horizontal or diagonal. An alternative way to approach the problem of exposed pipes is to actually make them a feature of the room by picking the pipework out in bright strong colours. {{B}}Extract 3{{/B}} Cooking takes second place in this charming room which; with its deep armchairs, is more of a sitting room than a kitchen, and the new Rayburn stove as a good Choice, as it blends in well with the old brick and beamed fireplace. There are no fitted units or built-in appliances, so all food preparation is done at the big farmhouse table in the foreground; and the china, pots and pans have been deliberately left on show to make an attractive display, What about the kitchen sink? It's hidden away behind an archway which leads into a small scullery. Here there's a second cooker and — in the best farmhouse tradition — a huge walk-in larder for all food storage.

单选题Directions: In this section you will read several passages. Each one is followed by several questions about it. You are to choose ONE best answer, A. B. C. or D. to each question. The momentum towards open publishing looks unstoppable but more still needs to be done to make science truly accessible, says Stephen Curry. If you would like to read the latest research from my lab, be my guest. Our report on a protein from a mouse version of the winter vomiting virus has just been published in the journal PLoS One and is available online for free—to anyone. Contrast that with my first paper, published in 1990, which you could only have read if you had access to a university library with an expensive subscription to the journal Biochemistry. Back in 1990—before the world wide web—that was how scientific publishing was done. Today it is being transformed by open access publishers like the Public Library of Science. Rather than being funded by journal subscriptions, these publishers charge authors or their institutions the cost of publication and make their papers available for free online. Many scientists are passionate supporters of open access and want to see the old model swept away. They have launched a protest movement dubbed the Academic Spring and organised a high-profile boycott of journals published by Elsevier. And the tide appears to be turning in their favour. This week the Finch Report, commissioned by the U.K. government, recommended that research papers—especially those funded by the taxpayer—should be made freely available to anyone who wants to read them. Advocates of open access claim it has major advantages over the subscription model that has been around since academic journals were invented in the 17th century. They argue that science operates more effectively when findings can be accessed freely and immediately by scientists around the world. Better yet, it allows new results to be data-mined using powerful web-crawling technology that might spot connections between data—insights that no individual would be likely to make. But if open access is so clearly superior, why has it not swept all before it? The model has been around for a decade but about nine-tenths of the approximately 2 million research papers that appear every year are still published behind a paywall. Part of the reason is scientists' reluctance to abandon traditional journals and the established ranking among them. Not all journals are equal—they are graded by impact factor, which reflects the average number of times that the papers they publish are cited by others. Nature's impact factor is 36, one of the highest going, whereas Biochemistry's is around 3.2. Biochemistry is well regarded—many journals have lower factors—but a paper in Nature is still a much greater prize. Unfortunately, it is prized for the wrong reasons. Impact factors apply to journals as a whole, not individual papers or their authors. Despite this, scientists are still judged on publications in high-impact journals; funding and promotion often depend on it. Consequently few are willing to risk bucking the trend. This has allowed several publishers to resist calls to abandon the subscription model. Another reason for the slowness of the revolution is concern about quality. Unlike many traditional journals, PLoS One does not assess the significance of research during peer review; it simply publishes all papers judged to be technically sound. However, this concern proved unfounded. PLoS One now publishes more papers than any other life science journal and has an impact factor of 4.4. The world of scientific publishing is slowly changing and the hegemony of established journals is being challenged. Shaken by the competition, more of them are offering variants of open access. At the high end of the market, Nature is about to face competition from eLife, an open access journal to be launched later this year. Adding to the momentum, U.K. government research councils are increasingly insisting that the research they pay for be published in open access journals. The European Union is poised to do the same for the science it funds. In the U.S., a bill now before Congress would require all large federal funders to make papers freely available no later than six months after publication.

单选题Questions 21-25 Once it was possible to define male and female roles easily by the division of labor. Men worked outside the home and earned the income to support their families, while women cooked the meals and took care of the home and the children. These roles were firmly fixed for most people, and there was not much opportunity for women to exchange their roles. But by the middle of this century, men"s and women"s roles were becoming less firmly fixed. In the 1950s, economic and social success was the goal of the typical American. But in the 1960s a new force developed called the counterculture. The people involved in this movement did not value the middle-class American goals. The counterculture presented men and women with new role choices. Taking more interest in childcare, men began to share child-raising tasks with their wives. In fact, some young men and women moved to communal homes or farms where the economic and childcare responsibilities were shared equally by both sexes. In addition, many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam. In terms of numbers, the counterculture was not a very large group of people. But its influence spread to many parts of American society. Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on "overtime" work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods. In the 1970s, the feminist movement, or women"s liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional women"s jobs as public school teaching, nursing, and secretarial work. But some women began to enter traditionally male occupations: police work, banking, dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion. Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these transformations.

单选题 Gene therapy and gene based drugs are two ways we could benefit from our growing mastery of genetic science. But there will be others as well. Here is one of the remarkable therapies on the cutting edge of genetic research that could make their way into mainstream medicine in the coming years. While it's true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to mm into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so called stem cells haven't begun to specialize. Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells—brain cells in Alzheimer's, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few; if doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue. It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can't be controlled, and may have unforeseen limitations; but if efforts to understand and master stem cell development prove successful, doctors will have a therapeutic tool of incredible power. The same applies to cloning, which is really just the other side of the coin; true cloning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full fledged animal, genetically identical to its parent. For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year. Human cloning, on the other hand, may be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells: the potential to make healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true "miracle cure".
