单选题In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences, that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence—as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that violence never solves a problem but makes it more acute. The sheer horror, the bloodshed and the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us. The truly reasonable men who know where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is undermined by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social program. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law. Before we can even begin to contemplate peaceful co-existence between the races, we must appreciate each other"s problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchanging information. "Talk, talk, talk," the advocates of violence say, "all you ever do is talk, and we are none the wiser." It"s rather like the story of the famous barrister who painstakingly explained his case to the judge. After listening to a lengthy argument the judge complained that after all this talk, he was none the wiser. "Possible, my lord," the barrister replied, "none the wiser, but surely far better informed." Knowledge is the necessary prerequisite to wisdom; the knowledge that violence creates the evils it pretends to solve.

单选题The legend of Paul Revere"s midnight ride through the Massachusetts countryside in 1775 is known to most Americans, young and old. As the story goes, Paul Revere was a silversmith in Boston at the time of the American Revolution. When he learned that the British army planned to attack the towns and villages of Middlesex County, farmhouse and village hall, to warn the local revolutionary soldiers of the planned attack. Because of his warning (according to legend) the struggling American colonies were able to defeat the British in an important battle. One reason for the popularity of the legend may be the publicity it has received through Henry Wadsworth Longfellow"s commemorative poem, Paul Revere"s Ride. Longfellow wrote the poem in 1861 and it has since then become one of the most well-known and well-loved poems in the country. The poem certainly captures the sense of danger and excitement, met with courage and ingenuity which many Americans associate with the American Revolution. It is easy to understand why the poem evokes such a large audience. However, Longfellow"s poem contains a number of historical errors. According to Longfellow"s poem, Paul Revere instructed a friend to watch the movement of the British troops and determine whether they marched inland or towards their boats. The friend was then to hang lanterns in the tower of the Old Church in Boston: one lantern if the British marched by land and two lanterns if they marched by sea. The expression "one if by land and two if by sea," taken from Longfellow"s poem, has become very popular and is often quoted. But this idea contains two inaccuracies. First, the lanterns were hung in the tower of the Old Christ Church, not the Old North Church, which is in a completely different part of Boston and would not have been visible from Paul Revere"s lookout point. Second, Longfellow confused the meaning of the number of lanterns to be hung: the actual arrangement was "two if by land and one if by sea. " Not all of Longfellow"s historical mistakes are so minor. It seems as though Longfellow chose to emphasize the idea of one lone hero struggling against many opposing forces, with only his own abilities to rely on. But actually, Paul Revere was only one of three riders delegated to warn the Revolutionary soldiers about the coming attack. Some people feel that Longfellow"s errors are insignificant, and that the ideals of courage and cunning are the important features of both the poem and the historical events which inspired it. But others feel that, while it probably makes little difference how many lanterns were hung from which church tower, the poem"s emphasis on the solitary hero runs counter to the most valuable idea in the poem: the idea of unity and cooperation in the face of danger. Critics of the poem raise an important question: Longfellow"s poem tells a famous story, and tells it powerfully—but is it the right story?

单选题{{B}}Passage 2{{/B}} Watch a baby between six and nine months old, and you will observe the basic concepts of geometry being learned. Once the baby has mastered the idea that space is three-dimensional, it reaches out and begins grasping various kinds of objects. It is then, from perhaps nine to fifteen months, that the concepts of sets and numbers are formed. So far, so good. But now an ominous development takes place. The nerve fibers in the brain insulate themselves in such a way that the baby begins to hear sounds very precisely. Soon it picks up language, and it is then brought into direct communication with adults. From this point on, it is usually downhill all the way for mathematics, because the child now becomes exposed to all the nonsense words and beliefs of the community into which it has been so unfortunate as to have been born. Nature, having done very well by the child to this point, having permitted it the luxury of thinking for itself for eighteen months, now abandons it to the arbitrary conventions and beliefs of society. But at least the child knows something of geometry and numbers, and it will always retain some memory of the early halcyon days, no matter what vicissitudes it may suffer later on. The main reservoir of mathematical talent in any society is thus possessed by children who are about two years old, children who have just learned to speak fluently.

单选题Here are two elements in life that Americans do save carefully: time and labor. Americans are "slaves to nothing but the clock", it has been said. Time is treated as if it were an almost tangible entry. In their language, there are words associated with it; time can be budgeted, saved, wasted, stolen, killed, and cut. Americans also charge for time. It is a precious commodity to them. Many people have a rather acute sense of the shortness of each lifetime. Once the sands have run out of a person"s hourglass, they cannot be replaced. They want every minute to count. Since people value time highly, they hate someone else "wasting" it beyond a certain courtesy point. This affects the matter of patience. In the American system of values, patience is not a high priority. Many of them have what might be called "a short fuse". They begin to splutter and move restlessly about if they feel time is slipping away without some return—be this in terms of pleasure, work value or rest. Normally Americans do not assess their visitors in relaxed surroundings over prolonged small talk; much less do they take out for dinner, while they develop a pre-business sense of trust and rapport. Rapport to most of them is less important than performance. They seek out credentials of past performance rather than evaluating a business colleague through social manners. Since they generally assess and probe professionally rather than socially, they start talking business very quickly. Most Americans live in time segments by engagement calendars. These calendars may be divided into intervals as short as fifteen minutes. They often "give" a person two or three (or more) segments of their calendar, but in the business world they almost always have other appointments following hard on the heels of whatever they are doing. Time is therefore always ticking in their inner ear.

单选题Small, pink and very ugly. Hardly the qualities of a star, but they describe the deformed mouse that was the media darling at a recent science exhibition in Beijing. With a complex tissue structure in the shape of a human ear grafted on to its back, the rosy rodent was a stunning symbol of the serious strides China is making in the field of biotechnology. China is fast applying the latest life-science techniques learned from the West to aggressively pursue genome research. It's establishing its own centers of technical excellence to build a scientific base to compete directly with the United States and Europe. With a plentiful supply of smart young scientists at home and lots of interest abroad biotechnology is on the brink of a boom in China. And in the view of foreign scientists, Beijing is playing a clever hand, maximizing the opportunities open to them. For the moment, the cooperation exists mostly with Europe and the U.S. But Asia's other biotech leaders, Japan, Singapore and Korea, also are recognizing China's potential as an attractive low-cost base to conduct research. These partnerships——and China's advancement in the field of biotechnology——could help benefit the rest of Asia: China's rapid progress in improving crop yields will address food-security concerns in the region. In addition, China is more likely to focus on developing cheap technology that its predominantly poor population——and those of other Asian countries——can afford. There remain, however, serious barriers to the development of a strong biotech industry. Among them are a poor domestic legal framework, weak enforcement of intellectual-property rights and loose adherence to international standards. China is a signatory of the International Bio Safely Protocol, which should mean adherence to global standards governing the conduct of field trials. But some observers are skeptical. "The regulations look good, but I haven't met one scientist who believes they are being fully adhered to," says a European science analyst. If shortcuts are taken, then some of the recent scientific achievements trumpeted in the official press may never make it to market. But no matter how strict lab test are, other problems lie in wait. For example, there is a number of tasks it would take years to fulfill in the patents office, says one lawyer, leaving innovators with little protection if they take a product to market in China.
