问答题{{B}}Directions:{{/B}} Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written neatly on ANSWER SHEET 2. (46) {{U}}Classical physics defines the vacuum as a state of absence, which is said to exist in a region of space if there is nothing in it.{{/U}} In the quantum field theories that describe the physics of elementary particles, the vacuum becomes somewhat more complicated. Even in empty space, particles can appear spontaneously as a result of fluctuations of the vacuum. For example, an electron and a positron, or anti-electron, can be created out of the void. Particles created in this way have only a fleeting existence; they are annihilated almost as soon as they appear, and their presence can never be detected directly. (47){{U}} They are called virtual particles in order to distinguish them from real particles, whose lifetimes are not constrained in the same way, and which can be detected.{{/U}} Thus it is still possible to define that vacuum as a space that has no real particles in it. One might expect that the vacuum would always be the state of lowest possible energy for a given region of space. If an area is initially empty and a real particle is put into it, the total energy, it seems, should be raised by at least the energy equivalent of the mass of the added particle. (48) {{U}}A surprising result of some recent theoretical investigations is that this assumption is not invariably true, and there are conditions under which the introduction of a real particle of finite mass into an empty region of space can reduce the total energy.{{/U}} If the reduction in energy is great enough, an electron and a positron will be spontaneously created. Under these conditions the electron and positron are not a result of vacuum fluctuations but are real particles, which exist indefinitely and can be detected. In other words, under these conditions the vacuum is an unstable state and can decay into a state of lower energy; i.e., one in which real particles are created. The essential condition for the decay of the vacuum is the presence of an intense electric field. (49) {{U}}As a result of the decay of the vacuum,{{/U}} the space permeated by such a field can be said to acquire an electric charge, and it can be called a charged vacuum. The particles that materialize in the space make the charge manifest. An electric field of sufficient intensity to create a charged vacuum is likely to be found in only one place: in the immediate vicinity of a super heavy atomic nucleus, one with about twice as many protons as the heaviest natural nuclei known. (50) {{U}}A nucleus that large cannot be stable, but it might be possible to assemble one next to a vacuum for long enough to observe the decay of the vacuum.{{/U}} Experiments attempting to achieve this are now under way.

问答题Stylistics

问答题 Like other forms of life on this planet, human beings confront a basic task: to deal satisfactorily with their conflicts and thereby secure the advantages of community and cooperation. {{U}} {{U}} 16 {{/U}} {{/U}}{{U}}Unlike other forms of life, human beings are endowed with a capacity to reflect on this task and to search for better solutions by conscious thought and deliberate choices.{{/U}} The task of overcoming conflicts and achieving community and cooperation arises because human beings are unable and unwilling to live in complete isolation. {{U}} {{U}} 17 {{/U}} {{/U}}{{U}}The advantages of cooperation and community life are so numerous and so obvious that they must have been evident to man from earliest times.{{/U}} By now, our ancestors have closed off the choice; for most of us the option of total isolation from a community is, realistically speaking, no longer open. {{U}} {{U}} 18 {{/U}} {{/U}}{{U}}Nonetheless, however strongly_ human beings are driven to seek the company of one another, and despite thousands of years' practice they have never discovered a way in which they can live together without conflict{{/U}}. Conflict exists when one individual wishes to follow a line of action that would make it difficult or impossible for someone else to pursue his own desires. Conflict seems to be an inescapable aspect of the community and consequently of human being. Why conflict seems inescapable is a question that has troubled many people: philosophers, theologians, historians, social scientists, and doubtless a great many ordinary people. James Madison held that conflict was built into the very nature of men and women. Human beings have diverse abilities, he wrote in The Federalist, and these in turn produce diverse interests. {{U}} {{U}} 19 {{/U}} {{/U}}{{U}}"As long as man has irrational ideas, and he is at liberty to exercise it," Madison wrote, "different opinions will be formed."{{/U}} Whatever the explanation for conflict may be, and Madison's is but one of many, its experience is one of the prime facts of all community of life. Yet if this were the only fact, then human life would fit the description by the English political philosopher, Thomas Hobbes, in his Leviathan (1651). Hobbes describes mankind in a state of nature-a condition without government-having little in the way of agriculture, industry, trade, knowledge, arts, letters or society. {{U}} {{U}} 20 {{/U}} {{/U}}{{U}}"And which is worst of all," he concluded in a famous sentence, to exist without government would mean "continual fear, and danger of violent death and the life of man, solitary, poor, nasty and short."{{/U}}

问答题Each year in the United States more people are killed or injured in accidents—at home, at work or school, at play, or while traveling—than were killed or injured in the Vietnam War. In the early 1990s, about half of these accidental deaths were the result of motor-vehicle accidents. Other major causes of accidental deaths were falls, fires, and poisoning. On a worldwide basis, accidents involving motor-vehicles are the primary causes of accidental deaths, followed by accidents in industry and in the home. Efforts to lessen or to eliminate the hazardous conditions that cause accidents are known as safety measures. Safety is a growing concern around the world, and safety skills are being taken more seriously today than ever before. People have come to realize that safety skills can be learned, and most safety experts agree that it is possible to predict, and take steps to prevent the majority of accidents. Few accidents simply "happen". Most are caused by ignorance, carelessness, neglect, or lack of skill.

问答题France"s tradition of making exquisite luxuries dates back at least to the court of Louis XIV. 16 The sun king financed ebenistes (cabinet-makers), tapisseurs (upholsterers), menuisiers (carpenters) and other artisans who made beautiful and largely useless things for the court of Versailles. Bernard Arnault might be his heir. Mr. Amault is the chairman, chief executive and controlling shareholder of Moet Hennessy Louis Vuitton (LVMH), the world"s largest luxury group. 17 Over the past quarter-century he has transformed a small, nearly defunct clothing manufacturer into a conglomerate that controls more than 60 luxury brands. Credit Suisse, a bank, predicts that LVMH"s combined sales will reach ? 27 billion ($33 billion) this year. Its profits in 2011 were ? 3.5 billion and its market capitalization is a cork-popping ? 62 billion. LVMH is more profitable than other luxury groups. "LVMH is like a mini Germany," boasts an insider. Like that country"s Mittelstand, it has built a reputation for craftsmanship and quality that people are happy to pay extra for. 18 The difference is, the Mittelstand makes unsexy things such as machine tools and shaving brushes, whereas LVMH makes champagne hand-bags and other objects of desire. Also like the Mittelstand, LVMH energetically pursues opportunities abroad. 19 After years of hard marketing, it has persuaded much of Asia"s new middle class that its wares confer a whiff of European sophistication. Sales in Asia (Japan except) accounted for 27% of the total in 2011, up from 17% in 2001. In Japan, which generated 15% of the group"s sales a decade ago, a startling 85% of women now own a Louis Vuitton product. It takes a rare talent to be ubiquitous and yet retain an air of exclusivity. A final similarity is that, like the Mittelstand, LVMH is made up of lots of family firms. The difference is that the ones that make up LVMH have been swallowed by a hungry conglomerate. Some didn"t object. Last year LVMH bought Bulgari, an Italian jeweler, for ? 4.3 billion. The Bulgari family were happy to take the cash. 20 Their business had hit a rough patch after the collapse of Lehman Brothers in 2008, and they thought Mr. Arnault would make a good sugar daddy for their brand.
