Since clothes are such an important source of social information, we can use them to manipulate people's impression to us. Our appearance assumes particular significance in the initial phases of interaction that is likely to occur. An elderly middle-class man or woman may be alienated by a young adult who is dressed in an unconventional manner, regardless of the person's education, background, or interests. People tend to agree on what certain types of clothes mean. Adolescent girls can easily agree on the lifestyles of girls who wear certain outfits, including the number of boyfriends they likely have had and whether they smoke or drink. Newscasters, or the announcers who read the news on TV, are considered. to be more convincing, honest, and competent when riley are dressed conservatively. And college students who view themselves as taking an active role in their interpersonal relationships say they are concerned about the costumes they must wear to play these roles successfully. Moreover. many of us can relate instances in which the clothing we wore changed the way we fell about ourselves and how we acted. Perhaps you have used clothing to gain confidence when you anticipated a stressful situation, such as a job interview, or a court appearance. In the workplace, men have long had well-defined {{U}}precedents{{/U}} and role models for achieving success. It has been otherwise for women. A good many women in the business world are uncertain about the appropriate mixture of "masculine" and "feminine" attributes they should convey by their professional clothing. The variety of clothing alternative to women has also been greater than that available for men. Male administrators tend to judge women more favorable for managerial positions when the women display less "feminine" grooming—shorter hair, moderate use of makeup, and plain tailored clothing. As one male administrator confessed. "An attractive woman is definitely going to get a longer interview, but she won't get a job."

单选题The Greek"s lofty attitude toward scientific research--and the scientists" contempt of utility-was not a long time dying. For a millennium after Archimedes, this separation of mechanics from geometry prevented fundamental technological progress and in some areas restrained it altogether. But there was a still greater obstacle to change until the very end of the Middle Ages-the organization of society. The social system of fixed class relationships that prevailed through the Middle Ages itself made improvement impossible. Under this system, the labouring masses, in exchange for the bare necessities of life, did all the productive work, while the privileged few--priests, nobles, and kings--concerned themselves only with ownership and maintenance of their own position. In the interest of their prerogatives they did achieve considerable progress in defence, in war making, in government, in trade, and in the arts of leisure, but they had no familiarity with the processes of production. On the other hand, the labourers, who were familiar with manufacturing techniques, had no incentive to improve or increase production to the advantage of their masters. Thus, with one class possessing the requisite knowledge and experience, but lacking incentive and leisure, and the other class lacking the knowledge and experience, there was no means by which technical progress could be achieved. The whole ancient world was built upon this relationship--a relationship as sterile as it was inhuman. The availability of slaves made efficient machinery needless. In many of the commonplace fields of human endeavour, actual stagnation prevailed for thousands of years. For about twenty-five centuries, two thirds of the power of the horse was lost because he wasn"t shod, and much of the strength of the ox was wasted because his harness wasn"t modified to fit his shoulders. For more than five thousand years, sailors were confined to rivers and coasts by a primitive steering mechanism which required remarkable little alteration (in the thirteenth century) to become a rudder(舵). With any originality at all, the ancient plough could have been put on wheels and the ploughshare shaped to bite and turn the sod instead of merely scratching it--but the originality wasn"t forthcoming. And the villager of the Middle Ages, like the men who first had fire, had a smoke hole in the center of the straw and reed roof of his one room dwelling, while the medieval charcoal burner( like his Stone Age ancestor) make himself a hut of small branches.

单选题The most subversive question about higher education has always been whether the college makes the student or the student makes the college. Along with skepticism, though, economic downturns also create one big countervailing force that pushes people toward college: many of them have nothing better to do. They have lost their jobs, or they find no jobs waiting for them after high school. In economic terms, the opportunity cost of going to school has been reduced. Over the course of the 1930s, the percentage of 17-year-old who graduated from high school jumped to 50 percent, from less than 30 percent. Boys—many of whom would have been working in better times—made up the bulk of the influx. In our Great Recession, students have surged into community colleges. So who is right—these students or the skeptics? It isn"t too much of an exaggeration to say that the field of labor economics has spent the past 30 years trying to come up with an answer. In one paper after another, economists have tried to identify the portion of a person"s success for which schooling can fairly claim credit. One well-known study, co-researched by Alan Krueger, a Princeton professor now serving as the Treasury Department"s chief economist, offered some support for the skeptics. It tracked top high-school students through their 30s and found that their alma maters had little impact on their earnings. Students who got into both, say, the University of Pennsylvania and Penn State made roughly the same amount of money, regardless of which they chose. Just as you might hope, the fine-grain status distinctions that preoccupy elite high-school seniors ( and more to the point, their parents ) seem to be overrated. The rest of the evidence, however, has tended to point strongly in the other direction. Several studies have found a large earnings gap between more and less-educated identical twins. Another study compared young men who happened to live close to a college with young men who did not. The two groups were similar except for how easy it was for them to get to school, and the upshot was that the additional education attained by the first group lifted their earnings. "College can"t guarantee anybody a good life," says Michael McPherson, an economist who runs the Spencer Foundation in Chicago, which finances education research. "But it surely ups the odds substantially."

单选题UN Secretary-General Kofi Annan visited the troubled Darfur region of western Sudan Thursday to consider ways to end the humanitarian crisis. More than a million people have been displaced in Darfur because of violence that human rights groups blame on government-backed militias. Kofi Annan spoke with tribal and women leaders about the problems facing refugees in a camp called Zam-Zam, outside the city of E1-Feshir. The leaders said they were afraid to return home because of possible attacks by the Janjaweed militias. But overall, they said, aid groups were looking after them relatively well in the camp. From there, the secretary-general and his delegation went to a camp just 30 minutes away where aid workers said the security and living situation was more desperate. But" the refugees were nowhere to be found. U.N. officials said some 4, 000 refugees, called internally displaced persons, or IDPs, had been in the camp the night before but they had been moved by Sudanese authorities. Jan Egeland, the U. N. "s undersecretary-general of humanitarian affairs, said the U.N. did not appreciate the authorities" actions. "But it was in our program actually to show the secretary-general and the secretary-general wanted to see how IDPs live when there are no services" ,"And this was such a place." Mr. Egeland was then risked ff this was a deliberate ploy by Sudanese authorities. "I"m sure it has happened before and I"m sure it will happen again. "The refugees moved to another camp are among the one million people in Darfur driven from their homes by Janjaweed militias. Human rights groups charge that the ethnic-Arab militias have been used by the government to terrorize the Darfur"s civilian population, which is ethnic-African, as part of efforts to put down an armed rebellion. Sudanese authorities deny supporting the Janjaweed and say they are working to disarm them. Until recently, they allowed little access to the region by aid workers. The conflict has given rise to what the U.N. calls the world"s worst humanitarian crisis today. Refugees face hunger, epidemics (传染病)and continued attacks in camps in Darfur or over the border in Chad. From Darfur, Mr. Annan flew to Chad"s capital, Ndjamena, for more discussions on the Darfur crisis. He is expected to return to Sudan"s capital, Khartoum, Friday.
