单选题In March 1974 one of the most astonishing archaeological discoveries of the twentieth century was unearthed in the county of Lintong, Shaanxi Province. An entire army of life-sized warriors and horses, buried for more than 2200 years, began to be uncovered. These replicas had been placed in trenches around the still-unexcavated tomb of Qinshihuang, the First Emperor of the Qin Dynasty(221-207 B.C.). Each of the many hundreds of life-sized warriors was constructed of baked clay and painted with a variety of colors. Most were obviously intended as individual portraits. The head shapes of these figures and the expressions on their faces were, more or less, individualized, and so each man could be identified as to his place of regional origin. The square-faced, broad-foreheaded, prominent-cheekboned, heavy-featured, big-mouthed and wide-cheeked ones were modeled after natives of central Shaanxi. The shorter, round-faced, sharp-chinned, and thin-lipped soldiers were modeled after persons from the province of Sichuan. Others were clearly from Gansu, and there were some who appeared to be members of various minorities in northwestern China. Each had its own hairdo: the ones with long hair had the knot at the right side of the head because the Qin people esteemed the right. To the surprise of both Chinese and Western archaeologists, a few of the clay soldiers showed non-Chinese characteristics possibly being persons from as far away as Arabia or Persia. This was particularly surprising because it had long been assumed that there were no persons from outside China living there in such ancient times. Yet a century later the historical record does indicate limited contact with foreigners. There is one report in the annals of the Eastern Han Dynasty(A.D. 25-220)of a Roman juggler who arrived in China by way of Burma in A. D. 109, and another of the arrival of an envoy from Macedonia at about the same time. And the Roman historian Lucjus Amnase Floras mentions the coming of a Chinese envoy to Rome as early as the reign of Augustus(27 B.C.-A. D. 14). But extensive contacts between China and the West didn't really begin until the northern Silk Road was gradually developed after 138 B.C. This overland route started at present-day Xi'an and passed through the Western Corridor beyond the Yellow River, Xinjiang, Farghana(now Uzbekistan), Persia(Iran)and Tajik(Iraq)where it met western boundary of the Roman Empire. For more than a thousand years this northern Silk Road provided a route for caravans that brought to China dates, saffron powder and pistachio nuts from Persia; glass bottles from Egypt, and many other expensive and desirable goods from other parts of the world. And the caravans went home with their camels and horses loaded down by bolts of silk brocade and boxes filled with lacquer ware and porcelains. Another Silk Road, documented in the geography section of the History of Han Dynasty, was a sea route that began at the ports of Xuwen and Hepu on the Reizhou Peninsula in South China(near which the city of Beihai is now located), passed through the Malacca Strait and ended in Burma or the Huangchi Kingdom of southern India. More Chinese porcelains and silks reached Europe by this route than by the overland one because of pirates and storms at sea. Subsidiary branches of this Silk Road of the sea reached such places as Korea, Japan, and the Philippines to allow for the exchange of various goods not readily available over the land route. For example, as early as the third century A.D., the Philippines were shipping gold to China by this route.

单选题For some time past it has been widely accepted that babies—and other creatures— learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise. It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome. Papousek began his studies by using milk in the normal way to "reward" the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's response in situation where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on" a display of lights—and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side. Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of lights which pleased them, it was the success that they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.

单选题America is a country on the move. In unheard-of numbers, people of all ages are exercising their way to better health. According to the latest figures, 59 percent of American adults exercise regularly—up 12 percent from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they would be more attractive and confident if they were more active. It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads for everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity (宣传) for races held in American cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding—and sometimes safer—forms of exercise, such as walking and swimming, running remains the most popular form of exercise. As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously(强有力地) enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce considerable improvements in physical health in about three months.

单选题In the eyes of Unilever, its troubles mainly lie in

单选题Seeing and perceiving are ______.

单选题The component of the healthy personality that is the first to develop is the sense of trust. As with other personality components, the sense of trust is not something that develops independent of other manifestations of growth. It is not that infants learn how to use their bodies for purposeful movement, learn to recognize people and objects around them, and also develop a sense of trust. Rather, the concept "sense of trust" is a shortcut expression intended to convey the characteristic flavor of all the child's satisfying experiences at this early age. Studies of mentally ill individuals and observations of infants who have been grossly deprived of affection suggest that trust is an early-formed and important element in the healthy personality. Psychiatrists find again and again that the most serious illnesses occur in patients who have been sorely neglected or abused or otherwise deprived of love in infancy. Observations of infants brought up in emotionally unfavorable institutions or moved to hospitals with inadequate facilities for psychological care support these findings. A recent report says that "Infants under 5 months of age who have been in an institution for some time present a well-defined picture. The outstanding features are listlessness, relative immobility, quietness, poor sleep, an appearance of unhappiness, etc." Another investigation of children separated from their mothers at 6 to 12 months and not provided with an adequate substitute comes to much the same conclusion. Most significant for our present point, these reactions are most likely to occur in children who, up to the time of separation at 6 to 9 months of age, had a happy relation with their mothers, while those whose relations were unhappy are relatively unaffected. It is at about this age that the struggle between trusting and mistrusting the world comes to a climax, for it is then that children first perceive clearly that they and their environment are things apart. That at this point formerly happy infants should react do badly to separation suggests, indeed, that they had a faith that now has been shattered. In most primitive societies and in some sections of our own society, the attention accorded infants is more in line with natural processes. Throughout infancy the baby is surrounded by people who are ready to feed it, fondle it, and otherwise comfort it at a moment's notice. Moreover, these ministrations are given spontaneously and wholeheartedly, and without that element of nervous concern that may characterize the efforts of young mothers made self-conscious and insecure by our scientific age. We must not exaggerate, however. Most infants in our society too find smiles and comfort. As their own bodies come to be more dependable, there is added to the pleasures of increasing sensory response and motor control the pleasure of the mothers' encouragement. Then, too, psychologists tell us that mothers create a sense of trust in their children not by the particular techniques they employ but by the sensitiveness with which they respond to the children's needs and by their overall attitude.

单选题The shy girl felt______and uneasy when she could not answer her teacher's question.

单选题Will there ever be another Einstein? This is the undercurrent of conversation at Einstein memorial meetings throughout the year. A new Einstein will emerge, scientists say. But it may take a long time. After all, more than 200 years separated Einstein from his nearest rival, Isaac Newton. Many physicists say the next Einstein hasn"t been born yet, or is a baby now. That"s because the quest for a unified theory that would account for all the forces of nature has pushed current mathematics to its limits. New math must be created before the problem can be solved. But researchers say there are many other factors working against another Einstein emerging anytime soon. For one thing, physics is a much different field today. In Einstein"s day, there were only a few thousand physicists worldwide, and the theoreticians who could intellectually rival Einstein probably would fit into a streetcar with seats to spare. Education is different, too. One crucial aspect of Einstein"s training that is overlooked is the years of philosophy he read as a teenager—Kant, Schopenhauer and Spinoza, among others. It taught him how to think independently and abstractly about space and time, and it wasn"t long before he became a philosopher himself. The independence created by philosophical insight is—in my opinion—the mark of distinction between a mere artisan or specialist and a real seeker after truth, Einstein wrote in 1944. And he was an accomplished musician. The interplay between music and math is well known. Einstein would furiously play his violin as a way to think through a knotty physics problem. Today, universities have produced millions of physicists. There aren"t many jobs in science for them, so they go to Wall Street and Silicon Valley to apply their analytical skills to more practical—and rewarding—efforts. "Maybe there is an Einstein out there today," said Columbia University physicist Brian Greene, "but it would be a lot harder for him to be heard". Especially considering what Einstein was proposing. "The actual fabric of space and time curving? My God, what an idea!" Greene said at a recent gathering at the Aspen Institute. "It takes a certain type of person who will bang his head against the wall because you believe you"ll find the solution." Perhaps the best examples are the five scientific papers Einstein wrote in his "miracle year" of 1905. These "thought experiments" were pages of calculations signed and submitted to the prestigious journal Annalen der Physic by a virtual unknown. There were no footnotes or citations. What might happen to such a submission today? "We all get papers like those in the mail," Greene said. "We put them in the junk file."

单选题No reference book, perhaps no book of any kind except the Bible, is so widely used as "the dictionary". Even houses that have few books or none at all possess at least one dictionary; most business offices have dictionaries, and most typists keep a copy on their desks; at one time or another most girls and boys are required by their teachers to obtain and use a dictionary. Admittedly, the dictionary is often used merely to determine the correct spelling of words, or to find out the accepted pronunciation, and such a use is perhaps not the most important from an intellectual point of view. Dictionaries may, however, have social importance, for it is often a matter of some concern to the person using the dictionary for such purposes that he should not suggest to others, by misspelling a word in a letter, or mispronouncing it in conversation, that he is not "well-bred", and has not been well educated. Yet, despite this familiarity with dictionary, the average person is likely to have many wrong ideas about it, and little idea of how to use it profitably, or interpret it rightly. For example, it is often believed that the mere presence of a word in a dictionary is evidence that it is acceptable in good writing. Though most dictionaries have a system of marking words as obsolete, or in use only as slang, many people, more especially if their use of a particular word has been challenged, are likely to conclude, if they find it in a dictionary, that it is accepted as being used by writers of established reputation. This would certainly have been true of dictionaries a hundred years or so ago. For a long time after they were first firmly established in the eighteenth century, their aim was to include only what was used by the best writers, and all else was suppressed, and the compiler frequently claimed that this dictionary contained no "low" words. Apparently this aspect of the dictionary achieved such importance in the mind of the average person that most people today were unaware of the great change that has taken place in the compilation of present-day dictionaries. Similarly, the ordinary man invariably supposes that one dictionary is as good and authoritative as another, and, moreover, believes that "the dictionary" has absolute authority, and quotes it to clinch arguments. Although this is an advantage, in that the dictionary presents a definition the basic meaning of which can't be altered by the speaker, yet it could be accepted only if all dictionaries agreed on the particular point in question. But ultimately the authority of the dictionary rests only on the authority of the man who compiled it, and, however careful he may be, a dictionary-maker is fallible: reputable dictionaries may disagree in their judgments, and indeed different sections of the same dictionary may differ.

单选题In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are sever over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality(道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach (说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.

单选题Social customs and ways of behaving change. Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behaviour for a man to smoke on street. No man who thought of himself by smoking when a lady was in a room. Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it matter? Should you use both hands when you are eating? Should leave one in your lap, or on the table? The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a woman or offer their seat to a woman, and so will most Americans. Promptness is important both in England and in America. That is, if a dinner invitation is for 7 o'clock, the dinner guest either arrives close to that time or calls up to explain his delay. The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable—especially if they are your guests. When the food was served, one of the guests started to eat his peas with a knife. The other guests were amused or shocked, but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.
