单选题{{B}}Passage Four{{/B}} Another month, another dismal set of job figures. America pulled out of its last economic recession way back in November 2001, yet the country's "jobs recession" finished only last autumn, when 2.7 million jobs had been lost since the start of the slowdown. Now, though economic growth has bounced back, new jobs refuse to do the same in this, the third year of recovery. In February, a mere 21,000 jobs were created, according to the official payroll survey, at a time when George Bush's economists forecast 2.6 million new jobs for 2004 mounting alarm at the White House, and increased calls for protection against what a growing number of Americans see as the root of most ills: the "outsourcing" of jobs to places like China and India. Last week the Senate approved a bill that forbids the outsourcing of government contracts--a curious case of a government guaranteeing not to deliver value-for-money to taxpayers. American anxiety over the economy appears to have tipped over into paranoia and self-delusion. Too strong? Not really. As The Economist has recently argued--though in the face of many angry readers--the jobs lost are mainly a cyclical affair, not a structural one. They must also be set against the 24 million new jobs created during the 1990s. Certainly, the slow pace of job-creation today is without precedent, but so were the conditions that conspired to slow a booming economy at the beginning of the decade. A stock market bubble burst, and rampant business investment slumped. Then, when the economy was down, terrorist attacks were followed by a spate of scandals that undermined public trust in the way companies were run. These acted as powerful headwinds and, in the face of them, the last recession was remarkably mild. By the same token, the recovery is mild, too. Still, in the next year or so, today's high productivity growth will start to translate into more jobs. Whether that is in time for Mr. Bush is another matter. As for outsourcing, it is implausible now, as Lawrence Katz at Harvard University argues, to think that outsourcing has profoundly changed the structure of the American economy over just the past three or four years. After all, outsourcing was in full swing--both in manufacturing and in services--throughout the job-creating 1990s. Government statisticians reckon that outsourced jobs are responsible for well under 1% of those signed up as unemployed. And the jobs lost to outsourcing pale in comparison with the number of jobs lost and created each month at home.

单选题{{B}}练习二{{/B}} Extraordinary creative activity has been characterized as revolutionary, flying in the face of what is established and producing not what is acceptable but what will become accepted. According to this formulation, highly creative activity transcends the limits of an existing form and establishes a new principle of organization. However, the idea that extraordinary creativity transcends established limits is misleading when it is applied to the arts, even though it may be valid for the sciences. Differences between highly creative art and highly creative science arise in part from differences in their goals. For the sciences, a new theory is the goal and end result of the creative act. Innovative science produces new propositions in terms of which diverse phenomena can be related to one another in more coherent ways. Such phenomena as a brilliant diamond or a nesting bird are relegated to the role of data, serving as the means for formulating or testing a new theory. The goal of highly creative art is very different: the phenomenon itself becomes the direct product of the creative act. Shakespeare's Hamlet is not a tract about the behavior of indecisive princes or the uses of political power, nor is Picasso's painting Guernica primarily a propositional statement about the Spanish Civil War or the evils of fascism. What highly creative artistic activity produces is not a new generalization that transcends established limits, but rather an aesthetic particular. Aesthetic particulars produced by the highly creative artist extend or exploit, in an innovative way, the limits of an existing form, rather than transcend that form. This is not to deny that a highly creative artist sometimes establishes a new principle of organization in the history of an artistic field: the composer Monteverdi, who created music of the highest aesthetic value, comes to mind. More generally, however, whether or not a composition establishes a new principle in the history of music has little bearing on its aesthetic worth. Because they embody a new principle of organization, some musical works, such as the operas of the Florentine Camerata, are of signal historical importance, but few listeners or musicologists would include these among the great works of music. On the other hand, Mozart's The Marriage of Figaro is surely among the masterpieces of music even though its modest innovations are confined to extending existing means. It has been said of Beethoven that he toppled the rules and freed music from the stifling confines of convention. But a close study of his compositions reveals that Beethoven overturned no fundamental rules. Rather, he was an incomparable strategist who exploited limits—the rules, forms, and conventions that he inherited from predecessors such as Haydn and Mozart, Handel and Bach--in strikingly original ways.

单选题Tina, a 10-lb 2-oz baby, was born into the Rodriguez home. The parents were delighted to have her, and she was given much love and attention. She seemed to grow up very normally, but did learn to talk a bit later than her two older siblings did. One day when she was about 3 years old, she fell off a swing and hurt her head, and had to have a few stitches to close a small wound. Several times after this the parents noticed that she would forget little things. It did not bother them until she enrolled in school, when she was 5 years and 10 months of age. At first she was anxious to go to school, but soon things began to change. She complained of being sick, and very often at school she had to use the restroom. The teacher complained that the child spent much of her time just gazing. She liked to talk to her friends, and often got into trouble with the teacher because she would not get her work done. Most times she completed no more than half an assignment. Her parents noted that she seemed to have lost her cheerfulness at home, and she often came home grumpy and complained that no one wanted to play with her. The longer she stayed in school, the worse her behavior became, and to top it all, in early spring the teacher concluded that Tina was not learning anything and was going to have to repeat the first grade.

单选题Text 3 Disagreements among economists are legendary, but not on the issue of free trade. A recent survey of prominent economists both conservative and liberal concluded that an economist who argues for restricting international trade is almost as common today as a physician who favors leeching. Why the consensus? International free trade, economists agree, makes possible higher standards of living all over the globe. The case for free trade rests largely on this principle: as long as trade is voluntary, both partners benefit, otherwise they wouldn't trade. The buyer of a shirt, for example, values the shirt more than the money spent, while the seller values the money more. Both are better off because of the sale. Moreover, it doesn't matter whether the shirt salesman is from the United States or Hong Kong(or anywhere else). The vast majority of American manufactures face international competition. This competition forces companies to improve quality and cut costs. By contrast, protectionism encourages monopoly, lower quality and higher prices. Americans pay an enormous price for protectionism over $60 billion a year, or $1000 for a family of four. Thanks to protectionism, for example, American consumers pay twice the world price for sugar. Free trade also makes the world economy more efficient, by allowing nations to capitalize on their strengths. The United States has an advantage in food production, for instance, while Saudi Arabia has an advantage in oil. The Saudis could undertake massive irrigation to become self-sufficient in food, but it is more economical for them to sell oil and purchase food from us. Similarly, we could become self-sufficient in petroleum by squeezing more out of oil shale. But it is much less costly to buy some of our oil from Saudi Arabia. Trade between our two countries improves the standard of living in both. Protectionism is both wasteful and unjust. It taxes most heavily the people who can least afford it. Thus, tariffs that raise the price of shoes burden the poor more than the rich. Despite the powerful case for free trade, the United States and the rest of the world have always been protectionist to some degree. This is because free trade benefits the general public, while protectionism benefits special interest groups, which are better organized, better financed and more informed. To make matters worse, much of what we hear on this issue is misinformation spread by the special interests themselves.

单选题 Watch out! Here comes London Mayor Boris Johnson riding a bicycle from his new bike hire plan. "What We've put in a new form of public transport. These bikes are going to belong to everybody. " "More than 12000 people have signed up for the plan. They each receive a key at a cost of three pounds, with costs at one pound for a 24-hour membership, five pounds for seven days, and 45 pounds for an annual membership. " John Payne, a London teacher who cycles a lot, is among the first to use the system. "It's very comfortable. For people who don't cycle much I think it'll he very useful. But for people who cycle regularly, they are possibly a bit slow, But they' re perfect for London streets, very strong. I think they'll he very widely used. " And Johnson says it's of good value. "I think it's extremely good value. The first half hour is free. If you cycle smart and you cycle around London on—most journeys in London take less than half an hour, you can cycle the whole day free. "Some 5000 bikes are currently available at over 300 docking stations(租车点) in central London. Johnson says the city will gradually expand the system. "Clearly one of our ambitions is to make sure that in 2012 when the world comes to London, they will be able to use London hire bikes to go to the Olympic Stadiums. "

单选题There's a simple premise behind what Larry Myers does for a living: If you can smell it, you can find it. Myers is the founder of Auburn University's Institute for Biological Detection Systems, the main task of which is to chase the ultimate in detection devices—an artificial nose. For now, the subject of their research is little more than a stack of gleaming chips tucked away in a laboratory drawer. But soon, such a tool could be hanging from the belts of police, arson (纵火) investigators and food-safety inspectors. The technology that they are working on would suggest quite reasonable that, within three to five years, we'll have some workable sensors ready to use. Such devices might find wide use in places that attract terrorists. Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination. The implications for revolutionary advances in public safety and the food industry are astonishing. But so, too, are the possibilities for abuse: Such machines could determine whether a woman is ovulating (排卵), without a physical exam—or even her knowledge. One of the traditional protectors of American liberty is that it has been impossible to search everyone. That's getting not to be the case. Artificial biosensors created at Auburn work totally differently from anything ever seen before. AromaScan, for example, is a desktop machine based on a bank of chips sensitive to specific chemicals that evaporate into the air. As air is sucked into the machine, chemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them. Those current changes are logged into a computer that sorts out odors based on their electrical signatures. Myers says they expect to load a single fingernail-size chip with thousands of odor receptors (感受器), enough to create a sensor that's nearly as sensitive as a dog's nose.

单选题{{B}}Passage Three{{/B}} It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. You either have science or you don't, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful bits. The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far they are from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted. But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can't be answered, sooner or later, including even the matter of consciousness; to be sure, there may well be questions we can't think up, ever, and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention.
