单选题Have you ever felt your life go into slow motion as you realize something bad is happening? You might have just knocked over a wine glass or noticed a car hurtling towards you, for example. Now scientists have measured exactly how much these attention-grabbing(引人注意的)events slow down our perception of the world around us. Another example of the world appearing to slow down is when you are hanging on the phone waiting for someone to pick up at the other end. If your attention wanders while you're waiting, then suddenly switches back,you will probably hear what seems like a longer than usual silence before hearing the dialling tone again. For you, time will have momentarily slowed. To see how our perception of time changes when something new happens, Vincent Walsh and his colleagues put headphones on volunteers and played eight beeps to their right ears. The gap between each beep was exactly i second, except for the gap between the fourth and fifth beeps, which the scientists could make shorter or longer. They altered the length of this gap until the volunteers estimated it was the same length as the other gaps. The researchers found that, on average, people judge a second slightly short, at 955 milliseconds. In the second part of the experiment, the first four beeps were played to the subjects' right ear, but the other four were then played to their left. Again, the volunteers were asked to estimate when the gap between the fourth and fifth beeps was the same as the others. This time they judged a second to be even shorter at 825 milliseconds long. Perceiving a second to be much shorter than it is makes you feel as though the world has gone into slow motion, since less happens in that slice of time. Walsh thinks the effect could have evolved to give us a fraction more time to react to potentially threatening events. Last year, Kielan Yarrow, a British psychologist found a similar effect with vision. When you glance at a clock, the first second will seem longer than it really is. Yarrow's results showed that time appeared to slow down by a similar amount as Walsh found. Previous studies have shown that cooling the body slows down our perception of time while warming it up has the opposite effect.

单选题When students arrive on campus with their parents, both parties often assume that the school will function in loco parentis, watching over its young charges, providing assistance when needed. Colleges and universities present themselves as supportive learning communities—as extended families, in a way. And indeed, for many students they become a home away from home. This is why graduates often use another Latin term, alma mater, meaning "nourishing mother." Ideally, the school nurtures its students, guiding them toward adulthood. Lifelong friendships are formed, teachers become mentors (导师), and the academic experience is complemented by rich social interaction. For some students, however, the picture is less rosy. For a significant number, the challenges can become overwhelming. In reality, administrators at American colleges and universities are often obliged to focus as much on the generation of revenue as on the new generation of students. A troubled or even severely disturbed student can easily fall through the cracks. Public institutions in particular are often faced with tough choices about which student support services to fund, and how to manage such things as soaring health-care costs for faculty and staff. Private schools are feeling the pinch as well. Ironically, although tuition and fees can increase as much as 6.6 percent in a single year, as they did in 2007, the high cost of doing business at public and private institutions means that students are not necessarily receiving more support in return for increased tuition and fees. To compound the problem, students may be reluctant to seek help even when they desperately need it. Unfortunately, higher education is sometimes more of an information delivery system than a responsive, collaborative process. Just as colleges are sometimes ill equipped to respond to the challenges being posed by today's students, so students themselves are sometimes ill equipped to respond to the challenges posed by college life. Although they arrive on campus with high expectations, some students struggle with chronic shyness, learning disabilities, addiction, or eating disorders. Still others suffer from acute loneliness, mental illness, or even rage. We have created cities of youth in which students can pass through unnoticed, their voices rarely heard, their faces rarely seen. As class size grows in response to budget cuts, it becomes even less likely that troubled students, or even severely disturbed students, wilt be noticed. When they're not, the results can be tragic.

单选题The decades after 1830 were a period of disintegration and uncertainty in German philosophy. For almost half a century idealist philosophies, culminating in Hegel's grandiose system, had dominated the philosophical scene, revolving around such spiritual notions as transcendental ego, consciousness, presentation (Vorstellung ) , idea, mind, and spirit (Geist). The rapid collapse of German Idealism—that "gigantic mountain range" of creative thought, as Husserl called it in 1917, was due to a combination of causes. There was in the first place, accelerated progress in the natural sciences, ranging from physiology (Johannes Muller, Ernst Weber) to physics (Robert Mayer, Hermann Helmholtz) and chemistry (Justus von Liebig, Friedrich Whler). The success of the experimental approach visibly demonstrated the futility of all idealistic speculation about nature. Secondly, there was the rapid growth of technology (especially the construction of railways and the invention of the telegraph), combined with the process of industrialization (resulting in tensions between capital and labour which led to radical changes in the economic system). Moreover, new political ideas concerning popular participation in government led first of all to the abortive revolution of 1848 and resulted finally in the unification of Germany after the war of 1866. Next to philosophical idealism, the other great loser in this course of events was Christianity, especially protestant Christianity, a long-standing ally of idealism. The vacuum thus produced was often filled by vulgar materialist ideas along the line of Ludwig Buchner's Kraft und Stoff (1855). The more educated classes, however, had needs of a more refined nature, and they turned instead to Schopenhauerianism. Schopenhauer stood firmly in the great European tradition of idealism extending from Plato and Kant, but he nevertheless resolutely rejected post-Kantian, and more specifically Hegelian idealism. Schopenhauer combined the scientist's conviction of a blind causality reigning in the world of nature with a view according to which this world is none the less rooted in a subjective bestowal of sense. He combined the democratic feeling of compassion for all mankind with an elitist view on art, and a belief in the ultimate meaninglessness of history with an ontology in which the will is fundamental. But above all his philosophy, while rating Christianity rather low, made room for religion on better soil. the religion of India. The view of Indian thought current among educated circles in the second half of the nineteenth century in Germany was strongly influenced by Schopenhauer. Not only did he give popular currency to expressions such as "nirvana" and "the veil of maya", but also he may also be held responsible for the current amalgamation of all ideas which blew into Europe from the East. Neither Hinduism and Buddhism nor Brahmanism and Vedanta philosophy were clearly distinguished by Schopenhauer. On one point, however, he was particularly firm. Buddhism is the highest religion in the world, because it is an "atheistic religion" .Thus it not only surpasses Christian theism, but also comes close to Schopenhauer's own conception of the absolute. Schopenhauer's followers in Germany were therefore able to look down on the parochial Christian rituals practised in their country, while upholding the claim that they, too, were directed toward some higher entity however, vaguely conceived. Moreover, they could feel themselves close to the Vedas and Upanisads, considered to be the oldest and most venerable documents of human thought, while at the same time feeling superior to these Indian "myths" as a result of their own rootedness in the purely philosophical ideas of the Schopenhauerian system. To illustrate all this, I want to quote from a document which not only exemplifies this widespread attitude, but also deviates from it in a significant way. It will moreover display the typical framework of Husserl's own understanding of Indian thought. The document in question is a letter written by Thomas Masaryk (1850—1937) in 1876, while Masaryk (who later was to rise to fame as the thunder and first president of the Czechoslovakian state) was still a student of philosophy. The letter is addressed to Franz Brentano who had been for some years Masaryk's teacher at the University of Vienna, the capital of the Austro-Hungarian Empire. It was written from Leipzig in Germany where Masaryk moved in order to continue his studies. On 23 November 1876, he writes to Brentano....

单选题{{B}}Text 4{{/B}} Banking is about money; and no other familiar commodity arouses such excesses of passion and dislike. Nor is there any other about which more nonsense is talked. The type of thing that comes to mind is not what is normally called economics, which is inexact rather than nonsensical, and only in the same way as all sciences are at the point where they try to predict people's behavior and its consequences. Indeed most social sciences and, for example, medicine could probably be described in the same way. However, it is common to hear assertions of the kind "if you were left along to a desert island a few seed potatoes would be more use to you than a million pounds" as though this proved something important about money except the undeniable fact that it would not be much use to anyone in a situation where very few of us are at all likely to find ourselves. Money in fact is a token, or symbolic object, exchangeable on demand by its holders for goods and services. Its use for these purposes is universal except within a small number of primitive agricultural communities. Money and the price mechanism, i.e. , the changes in prices expressed in money terms of different goods and services, are the means by which all modern societies regulate demand and supply for these things. Especially important are the relative changes in price of different goods and services compared with each other. To take random example: the price of house-building has over the past five years risen a good deal faster than that of domestic appliances like refrigerators, but slower than that of motor insurance or French Impressionist paintings. This fact has complex implications for students of the industry, trade unionism, town planning, insurance companies, fine-art auctions, and politics. Unpacking these implications is what economics is about, but their implications for bankers are quite different. In general, in modem industrialized societies, services or goods produced in a context requiting a high service-content (e. g. a meal in a restaurant) are likely to rise in price more rapidly than goods capable of mass-production on a large scale. It is also a characteristic of highly developed economies that the number of workers employed in service industries tends to rise and that of workers employed in manufacturing to fall. The discomfort this truth causes has been an important source of tension in western political life for many years and is likely to remain so for many more.

单选题In only two decades Asian Americans have become the fastestgrowing the U. S. minority. As their children began moving up through the nation's schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nation's best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact' that Asian-American students who began their educations abroad arrived in the U.S. with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree. Most Asian-American students owe their success to the influence of parents who are deter- mined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian culture that breeds success, such as ideals that stress family values and emphasize education. Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the Victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.

单选题 I am addicted to electricity. So are you. And so is your business. We live in an "always on" world-air conditioners, streetlights, TVs, PCs, cell phones, and more. And with forecasts that we'll need 40% more electricity by 2030, determining how we can realistically feed our energy addiction without mining our environment is the critical challenge of the new century. Of course, we could buy energy-saving appliances or drive fuel-efficient cars. We can recycle cans, bottles, and newspapers. We can even plant carbon-absorbing trees. But, no matter how much we may wish they would, these acts by themselves won't satisfy our energy demands. To do that, we need a diverse energy mix that takes a practical, rather than emotional, approach. Enter nuclear energy. Nuclear alone won't get us to where we need to be, but we won't get there without it. Despite its controversial reputation, unclear is efficient and reliable. It's also clean, emitting no greenhouse gases or regulated air pollutants while generating electricity. And with nuclear power, we get the chance to preserve the Earth's climate while at the same tinge meeting our future energy needs. Moreover, many of the management woes that gave the early nuclear business a black eye have finally been overcome. A five-year project in Alabama was completed on time and very close to budget. Also, US-designed reactors have been built in about four years in Asia, and new nuclear plants on the drawing board for installation here in America will be licensed by the Nuclear Regulatory Commission under a speedier process that should be far more efficient than the one in place when the 104 nuclear facilities operating today were licensed. But this streamlined process will not compromise nuclear safety and security. The NRC holds nuclear reactors to the highest safety and security standards of any American industry. A two-day national security simulation in Washington, D.C., in 2002 concluded nuclear plants "are probably our best defended targets." And because of their advanced design and sophisticated containment structures, US nuclear plants emit a negligible amount of radiation. Even if you lived next door to a nuclear power plant, you would still be exposed to less radiation each year than you would receive in just one roundtrip flight from New York to Los Angeles. Here's the reality: The US needs more energy, and we need to get it without further harming our environment. Everything is a trade-off. Nothing is free, and nuclear plants are not cheap to build. But we have a choice to make: We can either continue the 30-year debate about whether we should embrace nuclear energy, or we can accept its practical advantages. Love it or not, expanding nuclear energy makes both environmental and business sense.
