单选题By 1,800 about half the population of Brazil had come from Africa. So had about half the population of Venezuela. So had a smaller but still large part of all the population of Trans-Atlantic republics, whether in North, Central or South Africa, or in the Caribbean islands. It was these men and women of African descent conquered the wilderness of the Americas, clearing and working in countless farms and plantations, founding and opening innumerable mines of iron or precious metals. Harsh and painful as it was, the overseas slave trade (like the not much less painful movement of millions of hungry and jobless men and women from Europe) laid the foundations of American republics. These Africans beyond the seas have their place in the story of Africa (the story of West Africa), for what they attempted and achieved was also a reflection of the strong and independent civilization from which they came. Consider, for example, the heroic and successful struggle for independence conducted by the slaves of the Caribbean land of St. Domingue. In 1789, at the moment of the French Revolution, this French colony in the Caribbean was probably the wealthiest colony in the world. Its tens of thousands of African slave-workers produced enormous quantities of sugar, whole European communities lived off the profits. When news of the Revolution in France reached St. Domingue, these slaves claimed their share in its ideals and benefits. They demanded their freedom. When denied this, they rose in revolt against their masters. In years of hard fighting against large armies sent by France, and afterwards against large armies sent by Britain, these men of St. Domingue won their freedom and founded the Republic of Haiti. Yet more than half these soldiers of freedom had made the "middle passage" across the Atlantic. More than half, in other words, had been born in Africa, had spent their childhood in Africa, and had learned in Africa their respect for freedom; while nearly all the rest were the children of parents or grandparents born in Africa. And they were led by Africans: by men of genius and courage such as Boukman, the unforgettable Toussaint Louverture, and Dessalines. Raised by Toussaint and his Africans, the banner of freedom across the Atlantic was carried from people to people. Many threw off their bondage. Large numbers of men of African origin fought in the armies that made the United States what they are today. It was a general of African descent, Antonio Maceo, who led the military struggle for Cuban independence against Spain in 1868. Like other men of vision, Maceo had no time for racism, for the false idea that one race of men is better or worse than any other. Some of the whites of Cuba disagreed with him. They were Spanish settlers who thought that white was going to be better than black even in an independent Cuba. One day Maceo was approached by a Spanish Cuban who suggested that the regiments of independence army should be divided into whites and non-whites. Maceo made him a reply which became famous in Cuba. "If you were not white," Maceo said to this man, "I would have you shot on the spot. But I do not wish to be accused of being racialist as you are, and so I let you go, but with the warning that I shall not be so patient another time. The revolution has no color./

单选题Income inequality in the United State remained relatively stable for a period of nearly forty years. Beginning in the 1970's, however, this period of stability ended, as the first signs of widening income inequality became apparent. Over the course of the 1970's and 1980's , an increasingly clear trend toward greater income inequality emerged. By the end of the 1980's, the top 20 percent of workers were receiving the largest share of income ever recorded by government figures, and the bottom three fifths were receiving the lowest shares ever recorded. This trend has continued into the 1990's and currently shows no signs of decline. When the indicators of growing inequality were first observed in the 1970's, some researchers argued that the effects were merely temporary artifacts of short-term labor market disturbances. The new occupational structure appears to be one with an increase of well-paid technical, scientific and professional jobs at the top, a sliding middle class, and a growing poorly-paid service and retail jobs at the bottom. Several important labor-force changes appeared to be contributing to the shifting occupational structure. As occupational reconstructing and growing income inequality have become increasingly evident, a heated debate as to the causes and magnitude of these changes arose. Two dominant bodies of thought emerged around the issue: the job-skill mismatch thesis and the polarization thesis. Mismatch theorists argue that there is an increasing distance between the high skill requirements of post-industrial jobs and the inadequate training and mediocre qualifications of workers. They see the post-industrial economy leaving behind unskilled workers, especially women and minorities. For the mismatch theorist, the trend toward greater inequality is temporary arid will dissipate once the supply of workers acquires the skills demanded by a post-industrial economy. And they predict that the workers will experience an upgrading in their wages over the long run. Polarization theorists, on the other hand, believe that the rise in inequality is permanent, a result of the shift to a service-based economy. This vision of the postindustrial economy is characteristically polarized. The problem according to these theorists, is the type of jobs being generated in the new economy, not worker attributes. Because they believe the causes are structural and permanent, polarization theorists would deny the efficacy of public policies designed to educate and train unskilled workers. They predict a long-term continuation of the trend towards increasing income inequality. Studies show that the long-run increase in income inequality is also related to changes in the Nation's labor market and its household composition. The wage distribution has become considerably more unequal with more highly skilled, trained and educated workers at the top experiencing real wage gains and those at the bottom real wage losses. One factor is the shift in employment from those goods-producing industries that have disproportionately provided high-wage opportunities for low-skilled workers, towards services that disproportionately employ college graduates, and towards low-wage sectors such as retail trade. But within industry, shifts in labor demand away from less-educated workers are perhaps a more important explanation of eroding wages than the shift out of manufacturing. Also cited as putting downward pressure on the wages of less-educated workers are intensifying global competition and immigration, the decline of the proportion of workers belonging to unions, the decline in the real value of the minimum wage, the increasing need for computer skills, and the increasing use of temporary workers.

单选题Before a big exam, a sound night's sleep Will do you better than poring over textbooks. That, at least, is the folk wisdom. And science, in the form of behavioral psychology, supports that wisdom. But such behavioral studies cannot distinguish between two competing theories of why sleep is good for the memory. One says that sleep is when permanent memories form. The other says that they are actually formed during the day, but then "edited" at night, to flush away what is superfluous. To tell the difference, it is necessary to look into the brain of a sleeping person, and that is hard. But after a decade of painstaking work, a team led by Pierre Maquet at Liege University in Belgium has managed to do it. The particular stage of sleep in which the Belgian group is interested is rapid eye movement (REM) sleep, when brain and body are active, heart rate and blood pressure increase, the eyes move back and forth behind the eyelids as if watching a movie, and brainwave traces resemble those of wakefulness. It is during this period of sleep that people are most likely to relive events of the previous day in dreams. Dr. Maquet used an electronic device called PET to study the brains of people as they practiced a task during the day, and as they slept during the following night. The task required them to press a button as fast as possible, in response to a light coming on in one of six positions. As they learnt how to do this, their response times got faster. What they did not know Was that the appearance of the lights sometimes followed a pattern—what is referred to as "artificial grammar". Yet the reductions in response time showed that they learnt faster when the pattern was present than when there was not. What is more, those with more to learn (i. e. the "grammar", as well as the mechanical task of pushing the button) have more active brains. The "editing" theory would not predict that, since the number of irrelevant stimuli would be the same in each case. And to eliminate any doubts that the experimental subjects were learning as opposed to unlearning, their response times when they woke up were even quicker than when they went to sleep. The team, therefore, concluded that the nerve connections involved in memory are reinforced through reactivation during REM sleep, particularly if the brain detects an inherent structure in the material being learnt. So now, on the eve of that crucial test, maths students can sleep soundly in the knowledge that what they will remember the next day are the basic rules of algebra and not the incoherent talk from the radio next door.

Mark your answers on ANSWER SHEET 1.{{B}}Text 1{{/B}} It may not have generated much interest outside energy and investment circles, but a recent comment by Tidewater, Inc. president Dean Taylor sent earthquakes through the New Orleans business community. In June, Taylor told the Houston Chronicle that the international marine services company—the world's largest operator of ships serving the offshore oil industry—was seriously considering moving its headquarters, along with scores of administrative jobs, from the Crescent City to Houston. "We have a lot of sympathy for the city," Taylor said. "But our shareholders don't pay us to have sympathy. They pay us to have results for them." It was the last thing the hurricane-scarred city needed to hear. Tidewater was founded here a little more than 50 years ago, and kept its main office in New Orleans throughout the oil bust of the 1980s and the following decades of industry consolidation, when dozens of energy firms all but abandoned New Orleans for greener pastures on the Texas coast. In the nearly two years since Hurricane Katrina ravaged the city, the pace of exodus has accelerated. complicating New Orleans' halting recovery; according to the local business weekly CityBusiness, the metropolitan area has lost 12 of the 23 publicly traded companies headquartered here, taking white-collar jobs, corporate community support and sorely needed taxpayers with them—and threatening to leave the city even more dependent on a tourismbased economy than it was before the storm. Making matters worse, some observers say, is the city leadership's apparent indifference 10 the bloodletting. Just weeks after Hurricane Katrina in August 2005, Mayor Ray Nagin, then in the very early stages of a heated reelection bid, dismissed warnings that many companies, like displaced residents, might opt to relocate. Nagin said he hoped they would stay. "But if they don't," he said with typical glibness, "I'll send them a postcard. "The comment might have been written off as one of Nagin's many verbal missteps. But in the months that followed, the warnings turned out in many cases to be true, even as the city's rebuilding effort languished, infrastructure repairs limped along, the state reimbursement program for damaged homes faltered and the New Orleans' infamous crime rate made a sickening comeback. New Orleans "wasn't considered a great city for doing business before the storm. People were always dribbling out," says Peter Ricchiuti, a professor of economics at Tulane University. While many of the companies that made it through the storm could stand to benefit from the city' s recovery, he says, Katrina may have hastened the loss of high-paying energy jobs. "We're losing the white-collar jobs and keeping the blue-collar jobs," he says. "We' re becoming much more of a blue-collar oil industry." One of the latest examples is Chevron Corp., which is building new offices in the northern suburbs, 40 miles north of the city across Lake Pontchartrain, and plans to transfer 550 employees from New Orleans to Covington by the end of the year. That would take well-paid people out of downtown New Orleans, a move that will impact the central business district's economy. "We made the decision in May, 2006, when our employees were making important housing decisions," says Qi Wilson, a Chevron spokesperson. The company, like many employees, decided the north shore offered better security should another hurricane strike, along with fewer of the post-Katrina headaches that still plague the city. The move "will make it easier to retain the talent we have, and to attract new talent," Wilson says.

单选题Most economists in the United States seem excited by the spell of the free market. Consequently, nothing seems good or normal that does not accord with the requirements of the free market. A price that is determined by the seller or, for that matter, established by anyone other than the aggregate of consumers seems harmful. Accordingly, it requires a major act of will to think of price-fixing (the determination of prices by the seller) as both "normal" and having a valuable economic function. In fact, price-fixing is normal in all industrialized societies because the industrial system itself provides, as an effortless consequence of its own development, the price-fixing that it requires. Modern industrial planning requires and rewards great size. Hence, a comparatively small number of large firms will be competing for the same group of consumers. That each large firm will act with consideration of its own needs and thus avoid selling its products for more than its competitors charge is commonly recognized by advocates of free-market economic theories. But each large firm will also act with full consideration of the needs that it has in common with the other large firms competing for the same customers. Each large firm will .thus avoid significant price-cutting, because price-cutting would be prejudicial to the common interest in a stable demand for products. Most economists do not see price-fixing when it occurs because they expect it to be brought about by a number of explicit agreements among large firms; it is not. Moreover, those economists who argue that allowing the free market to operate without interference is the most efficient method of establishing prices have not considered the economies of non-socialist countries other than the United States. These economies employ intentional price-fixing, usually in an overt fashion. Formal price-fixing by cartel and informal price-fixing by agreements covering the members of an industry are commonplace. Were there something peculiarly efficient about the free market and inefficient about price- fixing, the countries that have avoided the first and used the second would have suffered drastically in their economic development. There is no indication that they have. Socialist industry also works within a framework of controlled prices. In the early 1970"s. the Soviet Union began to give firms and industries some of the flexibility in adjusting prices that a more informal evolution has accorded the capitalist system. Economists in the Unites States have hailed the change as a return to the free market. But Soviet firms are no more subject to prices established by a free market over which they exercise little influence than are capitalist firms; rather, Soviet firms have been given the power to fix prices.

单选题The author would be most likely to agree with statements that ______.

单选题It was the best of times or, depending on your political and philosophical outlook, one of the foulest and most depraved. Rebellion seemed to be leaping from city to city, continent to continent, by some fiery process of contagion. Radical students filled the streets of Mexico city, Berlin, Tokyo, Prague. In the U. S. , Chicago swirled into near anarchy as cops battled antiwar demonstrators gathered at the Democratic Convention. And everywhere from Amsterdam to Haight-Ashbury, a generation was getting high, acting up. So, clearly, it was the year from hell--a collective "dive into extensive social and personal dysfunction," as the Wall Street Journal editorialized recently. Or, depending again on your outlook, a global breakthrough for the human spirit. On this, the 25th anniversary of 1968, probably the only thing we can all agree on is that '68 marks the beginning of the "culture wars," which have divided America ever since. Both the sides of the "culture wars" of the '80s and '90s took form in the critical year of'68. The key issues are different now--abortion and gay rights, for example, as opposed to Vietnam and racism--but the underlying themes still echo the clashes of '68: Diversity vs. conformity, tradition vs. iconoclasm, self-expression vs. deference to norms. "Question authority," in other words, vs. "Father knows best." The 25th anniversary of '68 is a good time to reflect, calmly and philosophically, on these deep, underlying choices. On one hand we know that anti-authoritarianism for its own sake easily degenerates into a rude and unfocused defiance: Revolution, as Abbie Hoffman put it, "for the hell of it." Certainly '68 had its wretched excesses as well as its moments of glory: the personal tragedy of lives undone by drugs and sex, the heavy cost of riots and destruction. One might easily conclude that the ancient rules and hierarchies are there for a reason--they're worked, more or less, for untold millenniums, so there's no point in changing them now. But it's also true that what "worked" for thousands of years may not be the best way of doing things. Democracy, after all, was onee a far-out, subversive notion, condemned by kings and priests. In our own country, it took all kinds of hell-raising, including a war, to get across the simple notion that no person is morally entitled to own another. One generation's hallowed tradition--slavery, or the divine right of kings--may be another generation's object lesson in human folly. '68 was one more awkward, stumbling, half-step forward in what Dutschke called the "long march" toward human freedom. Actually, it helped inspire the worldwide feminist movement.

单选题"We"re using the wrong word ," says Sean Drysdale, a desperate doctor from a rural hospital at Hlabisa in northern KwaZulu-Natal. "This isn"t an epidemic, it"s a disaster. " A recent UNIEF report, which states that almost one-third of Swaziland"s 900,000 people are infected with HIV, the virus that causes AIDS, supports this diagnosis. HIV is spreading faster in southern Africa than anywhere else in the world. But is anyone paying attention? Despite the fact that most of the world"s 33.5 million HIV/AIDS cases are in sub-Saharan Africa—with an additional 4 million infected each year—the priorities at last week"s Organization of African Unity summit were conflict resolution and economies development. Yet the epidemic could have a greater effect on economic development—or, rather, the lack of it—than many politicians suspect. While business leaders are more concerned about the 2K millennium bug than the long-term effect of AIDS, statistics show that the workfare in South Africa, for instance, is likely to be 20% HIV positive by next year. Medical officials and researchers warn that not a single country in the region has a cohesive government strategy to tackle the crisis. The way managers address AIDS in the workplace will determine whether their companies survive the first decade of the 21st century, says Deane Moore, an actuary for South Africa"s Metropolitan Life Insurance Company. Moore estimates that in South Africa there will be 580,000 new AIDS cases a year and a life expectancy of just 38 by 2010. "We"ll be back to the Middle Ages," says Drysdale, whose hospital is in one of the areas in South Africa with the highest rates of HIV infection. " The graph is heading toward the vertical . And yet people are still not taking it seriously. " Most southern African countries are simply too poor to supply more than basic health services, let alone medicines, to confront the crisis. Patients in some government hospitals in Harare have to supply their own bedding, food, drugs and, in some cases, even their own nurses. Zimbabwe"s frail domestic economy depends to a large extent on informal enterprises and small businesses, many of which are going bankrupt as AIDS takes its toll on owners and employees. "The ripple effect is devastating," says Harare AIDS researcher Rene Loewenson. More ominous are the implications for South Africa with a sophisticated industrial infrastructure as well as a widespread informal sector. While the South African government is active in promoting AIDS education, it hasn"t the money, manpower or material to cope with the attack of AIDS.

单选题Over the years, as the musical "Rent" has reached milestone after milestone—playing around 'the world in more than 200 productions from Boise to Little Rock to Reykjavik—the thousands of people who have been affected by this vibrant, gritty and compassionate work may well wonder what its creator, Jonathan Larson, would have thought of it all. Another milestone came on Monday .night. The original Broadway production of "Rent" opened at the Nederlander Theater l0 years ago this Saturday. That production, directed by Michael Greif, was an almost-intact transfer of the initial production at the New York Theater Workshop, which had opened three months earlier. To celebrate the anniversary the original cast members reassembled, rehearsed for two days and performed the show in a semi-staged version at the Nederlander on Monday. The event was a benefit for the New York Theater Workshop, for Friends in Deed (a support organization that gave comfort to several of Mr. Larson's friends dealing with H.I.V. infections.). and for the Jonathan Larson Performing Arts Foundation, which was set up by his family after the enormous success of "Rent". Before the performance, the co-chairmen of the benefit told the star-studded audience that more than $2 million' had been raised. Also addressing the crowd were Senator Charles E. Schumer and Mayor Michael R. Bloomberg, who praised "Rent" as a timeless work exemplifying "culture, community and creativity," in the mayor's words, and saluted the show's vast contributions to New York's theatrical life. Once again you could only think, "Would Jonathan ever have imagined all this?" Mr. Larson, who wrote the music, lyrics and books for his stage works, struggled for more than 10 years to get a producer to take a shot at one of his shows. Now he was being posthumously thanked for giving Broadway a creative and economic boost. "Rent" is the seventh longest running show in Broadway history. I count myself among those who were personally affected by Mr. Larson's work. because of the inadvertent role I played in the last hours of his life. In 1996 an editor at The Times tipped me off to the opening of a rock musical, inspired by. "La Boheme", which transplanted Puccini's struggling bohemians from Paris in the 1830's to the ‘East Village in 1990's. So on Jan. 24 I went to the New York Theater Workshop m see the dress rehearsal of "Rent", which was scheduled to open in February. That performance was pretty ragged, with technical glitches and a misbehaving sound system. But I was swept away by the sophistication and exuberance of Mr. Larson's music and the mix of tenderness and cleverness in his lyrics. After the show Mr. Larson and I sat down for an interview in the tiny ticket booth of the theater, the only quiet space we could find amid the post-rehearsal confusion. For almost an hour, this sad-eyed and boyish. creator talked about his approach to songwriting, his determination to bring the American musical tradition to the MTV generation, and about friends snuggling with H:I.V. infection who had inspired the show.
