单选题Passage 4 When men get stick，they act like babies ，say women . But maybe the fairer sex should learn something useful from these guys ——it could save their lives， say researchers at the University of Michigan. When women have a heart attack ,they're more likely to put off seeking help the men ,and after an attack,they're less likely to take steps to improve their health . What's the reason for the different responses? The results of a survey suggest that women are too tough; they think heart problem are simply not a big deal . When Steven Erickson and his colleagues asked 348 men and 142 women who had been admitted to the hospital for a heart attack about their symptoms and medication (用药情况)，they found that even though the women had more symptoms and were taking more medicine they rated their disease as being no more severe than the men did .

单选题In Second Nature, Nobel Prize-winning neuroscientist Gerald Edelman argues that the brain and mind are unified, but he has little patience with the claim that the brain is a computer. Fortunately for the general reader, his explanations of brain function are accessible, reinforced by concrete examples and metaphors. Edelman suggests that thanks to the recent development of instruments capable of measuring brain structure within millimeters and brain activity within milliseconds, perceptions, thoughts, memories, willed acts, and other mind matters traditionally considered private and impenetrable to scientific scrutiny now can be correlated with brain activity. Our consciousness (a "first-person affair" displaying intentionality, reflecting beliefs and desires, etc.), our creativity. The author describes three unifying insights that correlate mind matters with brain activity. First, even distant neurons will establish meaningful connections (circuits) if their patterns are synchronized. Second, experience can either strengthen or weaken synapses (neuronal connections). Finally, there is reentry, the continued signaling from one brain region to another and back again along massively parallel nerve fibers. Edelman concedes that neurological explanations for consciousness and other aspects of mind are not currently available, but he is confident that they will be soon. Meanwhile, he is comfortable hazarding a guess: "All of our mental life ... is based on the structure and dynamics of our brain," Despite this optimism about the explanatory powers of neuroscience, Edelman acknowledges the pitfalls in attempting to explain all aspects of the mind in neurological terms. Indeed, culture—not biology—is the primary determinant of the brain's evolution, and has been since the emergence of language, he notes. However, I was surprised to learn that he considers Sigmund Freud "the key expositor of the effects of unconscious processes on behavior. " Such a comment ignores how slightly Freud's conception of the unconscious, with its emphasis on sexuality and aggression, resembles the cognitive unconscious studied by neuroscientists. Still, Second Nature is well worth reading. It serves as a bridge between the traditionally separate camps of "hard" science and the humanities. Readers without at least some familiarity with brain science will likely find the going difficult at certain points. Nonetheless, Edelman has achieved his goal of producing a provocative exploration of "how we come to know the world and ourselves. /

单选题As he closed his service station at 1:20 one Sunday morning, Tony Payseur set on the ground a metal cash box containing $7,000. At home a short while later, he reached in the back of his car for the box. It was missing. Realizing that he must have left it outside the station, Payseur speeded back. The box was gone. Sunday morning, although he felt ill, Payseur went to work with his two sons. Then, in the middle of the afternoon, a man named Wayne came and told his story. Passing the station minutes after Payseur left the previous night, Brazzell had spotted the metal box. Thinking it was a tool-box someone had left accidentally; he stopped and picked it up. About 3 p.m. Sunday, Brazzell opened the box. Finding it filled with cash, he rushed to the station. "I couldn"t believe someone would be so honest," Payseur said it when he got back his box.

单选题Mark Twain once observed that giving up smoking is easy. He knew, because he' d done it hundreds of times himself. Giving up for ever is a trifle more difficult, apparently, and it is well known that it is much more difficult for some people than for others. Why is this so? Few doctors believe any longer that it is simply a question of will power. And for those people that continue to view addicts as merely "weak", recent genetic research may force a rethink. A study conducted by Jacqueline Vink, of the Free University of Amsterdam, used a database called the Netherlands Twin Register to analyze the smoking habits of twins. Her results, published in the Pharmacogenomics Journal, suggest that an individual's degree of nicotine dependence, and even the number of cigarettes he smokes per day, are strongly genetically influenced. The Netherlands Twin Register is a voluntary database that contains details of some 7,000 pairs of adult twins (aged between 15 and 70) and 28,000 pairs of childhood twins. Such databases are prized by geneticists because they allow the comparison of identical twins (who share all their genes) with fraternal twins (who share half). In this case, however, Dr. Vink did not make use of that fact. For her, the database was merely a convenient repository of information. Instead of comparing identical and fraternal twins, she concentrated on the adult fraternal twins, most of whom had completed questionnaires about their habits, including smoking, and 536 of whom had given DNA samples to the register. The human genome is huge. It consists of billions of DNA "letters", some of which can be strung together to make sense (the genes) but many of which have either no function, or an unknown function. To follow what is going on, geneticists rely on markers they have identified within the genome. These are places where the genetic letters may vary between individuals. If a particular variant is routinely associated with a particular physical feature or a behavior pattern, it suggests that a particular version of a nearby gene is influencing that feature or behavior. Dr. Vink found four markers which seemed to be associated with smoking. They were on chromosomes 3, 0, 10 and 14, suggesting that at least four genes are involved. Dr. Vink hopes that finding genes responsible for nicotine dependence will make it possible to identify the causes of such dependence. That will help to classify smokers better (some are social smokers while others are physically addicted) and thus enable "quitting" programs to be customized. Results such as Dr. Vink's must be interpreted with care. Association studies, as such projects are known, have a disturbing habit of disappearing, as it were, in a puff of smoke when someone tries to replicate them. But if Dr. Vink really has exposed a genetic link with addiction, then Mark Twain's problem may eventually become a thing of the past.

单选题To the people of ancient Egypt, life on earth was short. Life after death, however, was e-ternal. Therefore they built tombs of stone and they took their possessions with them into another world. The more important the people, the greater the tomb. The Pharaohs were the rulers of the country and when they died they became gods. Many of their tombs remain, and some have become a wonder of the world. These are the pyramids. The purpose of these stone mountains was to protect the burial chamber from the weather and from thieves who might try to steal the gold, jewels and precious possessions placed there to accompany the dead ruler into eternal life. Their shape, with four triangular sides spreading from a single point, represented the rays of the sun. Their position on the west bank of the River Nile was where the sun set every day and where they believed it began its journey into the other world. All the burial grounds in ancient Egypt were on the west bank of the river.

单选题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 rived 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 Nervous Break Down. Intelligent people do not have breakdown 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. Every one 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 breakdown. 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 The Quechua world is submerged, so to speak, in a cosmic magma that weighs heavily upon it. It possesses the rare quality of being as it were interjected into the midst of antagonistic forces, which in turn implies a whole body of social and aesthetic structures whose innermost meaning must be the administration of energy. This gives rise to the social organism known as the ayllu, the agrarian community that regulates the procurement of food. The ayllu formed the basic structure of the whole Inca empire. The central idea of this organization was a kind of closed economy, just the opposite of our economic practices, which can be described as open. The closed economy rested on the fact that the Inca controlled both the production and consumption of food. When one adds to this fact the religious ideas noted in the Quechua texts cited by the chronicler Santa Cruz Pachacuti, one comes to the conclusion that in the Andean zone the margin of life was minimal and was made possible only by the system of magic the Quechua constructed through his religion. Adversities, moreover, were numerous, for the harvest might fail at any time and bring starvation to millions. Hence the whole purpose of the Quechua administrative and ideological system was to carry on the arduous task of achieving abundance and staving off shortages. This kind of a structure presupposes a state of unremitting anxiety, which could not be resolved by action. The Quechua could not do so because his primordial response to problems was the use of magic, that is, recourse to the unconscious for the solution of external problems. Thus the struggle against the world was a struggle against the dark depths of the Quechua's own psyche, where the solution was found. By overcoming the unconscious, the outer world was also vanquished. These considerations permit us to classify Quechua culture as absolutely static or, more accurately, as the expression of a mere state of being. Only in this way can we understand the refuge it took in the germinative center of the cosmic mandala as revealed by Quechua art. The Quechua empire was nothing more than a mandala, for it was divided into four zones, with Cuzco in the center. Here the Quechua ensconced himself to contemplate the decline of the world as though it were caused by an alien and autonomous force.
