单选题 What's the one word of advice a well-meaning professional would give to a recent college graduate? China? India? Brazil? How about trade? When the Commerce Department reported last week that the trade deficit in June approached $ 50 billion, it set off a new round of economic doomsaying. Imports, which soared to $ 200.3 billion in the month, are subtracted in the calculation of gross domestic product. The larger the trade deficit, the smaller the GDP. Should such imbalances continue, pessimists say, they could contribute to slower growth. But there's another way of looking at the trade data. Over the past two years, the figures on imports and exports seem not to signal a double-dip recession—a renewed decline in the broad level of economic activity in the United States—but an economic expansion. The rising volume of trade—more goods and services shuttling in and out of the United State—is good news for many sectors. Companies engaged in shipping, trucking, rail freight, delivery, and logistics(物流) have all been reporting better than expected results. The rising numbers signify growing vitality in foreign markets—when we import more stuff, it puts more cash in the hands of people around the world, and U.S. exports are rising because more foreigners have the ability to buy the things we produce and market. The rising tide of trade is also good news for people who work in trade-sensitive businesses, especially those that produce commodities for which global demand sets the price—agricultural goods, mining, metals, oil. And while exports always seem to lag, U.S. companies are becoming more involved in the global economy with each passing month. General Motors sells as many cars in China as in America each month. While that may not do much for imports, it does help GM's balance sheet—and hence makes the jobs of U. S.-based executives more stable. One great challenge for the U. S. economy is slack domestic consumer demand. Americans are paying down debt, saving more, and spending more carefully. That's to be expected, given what we've been through. But there's a bigger challenge. Can U. S.-based businesses, large and small, figure out how to get a piece of growing global demand? Unless you want to pick up and move to India, or Brazil, or China, the best way to do that is through trade. It may seem obvious, but it's no longer enough simply to do business with our friends and neighbors here at home. Companies and individuals who don't have a strategy to export more, or to get more involved in foreign markets, or to play a role in global trade, are shutting themselves out of the lion's share of economic opportunity in our world.

单选题For laymen ethnology is probably the most interesting of the biological sciences for the very reason that it concerns animals in their normal activities and therefore, if we wish, we can assess the possible dangers and advantages in our own behavioral roots. Ethnology also is interesting methodologically because it combines in new ways very scrupulous field observations with experimentations in laboratories. The field workers have had some handicaps in winning respect for themselves. For a long time they were considered as little better than amateur animal-watchers—certainly not scientists, since their facts were not gained by experimental procedures: they could not conform to the hard-and-fast rule that a problem set up and solved by one scientist must be tested by other scientists, under identical conditions and reaching identical results. Of course many situations in the lives of animals simply cannot be rehearsed and controlled in this way. The fall flocking of wild free birds can't be, or the homing of animals over long distances, or even details of spontaneous family relationships . Since these never can be reproduced in a laboratory, are they then not worth knowing about? The ethnologists who choose field work have got themselves out of this impasse by greatly refining the techniques of observing. At the start of a project all the animals to be studied are live-trapped, marked individually, and released. Motion pictures, often in color, provide permanent records of their subsequent activities. Recording of the animals' voices by electrical sound equipment is considered essential, and the most meticulous notes are kept of all that occurs. With this material other biologists, far from the scene, later can verify the reports. Moreover, two field observers often go out together, checking each other's observations right there in the field. Ethnology, the word, is derived from the Greek ethos, meaning the characteristic traits or features which distinguish a group—any particular group of people or, in biology, a group of animals such as a species. Ethnologists have the intention of studying " the whole sequence of acts which constitute an animal's behavior. " In abridged dictionaries ethnology is sometimes defined simply as "the objective study of animal behavior," and ethnologists do emphasize their wish to eliminate myths.

单选题Germany, Europe"s economic powerhouse, does not lack courage: it rebounded from two world wars, digested reunification and has now powered ahead of neighbors still reeling from the financial crisis. It overhauled a rigid labor market and raised the retirement age to 67 with little fuss. Most recently, it simply decided to abandon nuclear power. With this boldness at the top comes obedience at the bottom—82 million Germans will wait at a pedestrian red light, even with no car in sight. But when it comes to empowering women, no Teutonic drive or respect seems to work—even under one of the world"s most powerful women, Chancellor Angela Merkel. Despite a batch of government measures and ever more passionate debate about gender roles, only about 14 percent of German mothers with one child resume full-time work, and only 6 percent of those with two. All 30 German stock index companies are run by men. Nationwide, a single woman presides on a supervisory board: Dr. Simone Bagel-Trah at Henkel. Eighteen months after the International Herald Tribune launched a series on the state of women in the 21st century with a look at Germany, the country has emerged as a test case for the push-and-pull of economics and tradition. For the developed world, Germany"s situation suggests that puzzling out how to remove enduring barriers to women"s further progress is one of the hardest questions to solve. In all European countries, from the traditionally macho southern rim to more egalitarian Nordic nations, the availability and affordability of child care, intertwined with traditional ideas about gender roles, have proved key factors in determining gender equality. The nature of male networks is another telling factor. Women remain a striking minority in top corporate circles, even in fiercely egalitarian countries like Sweden or the US where opportunities often go with one"s abilities. Very few countries approach 20 percent female representation on corporate executive boards. Yet if Swedish executive suites boast 17 percent women and the United States and Britain 14 Percent, in Germany it is 2 percent—as in India, according to McKinsey"s 2010 Women Matter report. One of the countries in most need of female talent—German birthrate is among the lowest in Europe and labor shortages in skilled technical professions are already 150,000—Germany is a place where gender stereotypes remain engrained in the mind, and in key institutions across society.

单选题In the passage" move about" means ______.

单选题The way people hold to the belief that a fun-filled, pain-free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain. As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, self-improvement. Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features. Couples with infant children are lucky to get a whole night"s sleep or a three-day vacation. I don"t know any parent who would choose the fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.
