单选题The world is undergoing tremendous changes. The rise of globalization, both an economic and cultural trend that has swept throughout the world, has forged new ground as we enter the 21st century. But are the effects of globalization always positive? Some say no. Michael Tenet, head of the International Institute for Foreign Relations in Atlanta, is worried about current resentment throughout the world toward the rise of globalization. "Ever since the 1980s and the economic collapse of the Asian Tigers in the late 1990s, there has been a re-evaluation of the role of globalization as a force for good, " he said. "Incomes in many countries have declined and the gap between the most rich and the most poor has been aggravated. Without further intervention by governments, we could see a tragedy expressed in an increased level of poverty throughout the Latin America and Asia. " Yet George Frank, an influential economist who works on Wall Street, sees no such danger. "Economic liberalization, increased transparency and market-based reforms have positive effect in the long run, even if market mechanisms can produce short-term destabilization problems," he said. "What is most important is that barriers to trade continue to fall so that active competition for consumer goods reduces prices and in turn raises the average level of income. " Others feel that globalization's cultural impact may be more important than its economic implications. Janice Yawee, a native of Africa, feels strongly that globalization is undermining her local culture and language. "Most of the world's dialects will become extinct under globalization. We're paving the world with McDonald's and English slang. It tears me up inside, " she said. Governments of different countries have had mixed responses to the wave of globalization. The United States is generally seen as an active proponent of greater free trade, and it certainly has enormous cultural influence by virtue of its near monopoly on worldwide entertainment. But other countries, most notably in Europe and developing nations, have sought to reduce the impact that globalization has on their domestic affairs. "When I was a boy we had very little to speak of, " says one Singaporean resident. "Now our country has developed into a booming hub for international finance. " Others, however, are not so optimistic. "Globalization is an evil force that must be halted, " a union official at a car plant in Detroit recently commented, "It's sucking away jobs and killing the spirit of our country. /

单选题There is little question that substantial labor-market differences exist between men and women. Among the most researched difference is the male-female wage gap. Many different theories aroused to explain why men earn more than women. One possible reason is based on the limited geographical mobility of married women [Robert Frank, 1978]. Family mobility is a joint decision in which the needs of the husband and wife are balanced to maximize family welfare. Job-motivated relocations are generally made to benefit the primary earner in the family. This leads to a constrained job search for the secondary earner, as he or she must search for a job in a limited geographic area. Since the husband is still the primary wage earner in many families, the job search of the wife may suffer. Individuals who are tied to a certain area are labeled "tied-stayers," while secondary earners, who move for the benefit of the family are labeled "tied-movers" [Jacob ～Mincer, 1978]. The wages of a tied-stayer or tied-mover may not be substantially lower if the family lives in or moves to a large city. If a large labor market has more vacancies, the wife may locate a wage offer near the maximum she would find with a nation-wide search. However, being a tied- stayer or tied-mover can lower the wife's wage if the family lives in or moves to a small community. A small labor market will reduce the likelihood of her finding a job that utilizes her skills, As a result she may accept a job for which she is overqualified and thus earn a lower wage. This hypothesized relationship between the likelihood "of being overqualified" and SMSA size is termed "differential overqualification." Frank 1978 and Haim Ofek and Yesook Merrill [1994] provide support for the theory of differential overqualification by finding that the male-female wage gap is grater in smaller SMSA's. While the results are consistent with the existence of differential overqualification, they may also result from other situations as well. Firms in small labor markets may use their monopsony power to keep wages down. Local demand shocks are found to be a major source of wage variation both across and within local labor markets [ Robert Topel, 1986]. Since large labor markets are generally more diversified, a demand shock can have a substantial impact on immobile workers in small labor markets. Another reason for examining differential overqualification involves the assumption that there are more vacancies in large labor markets. While there is little doubt that more vacancies exist in large labor markets, there are also likely to be more people searching for jobs in large labor markets, if the greater number of vacancies is offset by the larger number of searchers, it is unclear whether women will be more likely to be overqualified in small labor markets. Instead of relying on wages to determine if differential overqualifieation exists, we consider an explicit form of overqualifieation based on education.

单选题The average population density of the world is 47 persons per square mile. Continental densities range from no permanent inhabitants in Antarctica to 211 per square mile in Europe. In the western hemisphere, population densities range from about 4 per square mile in Canada to 675 per square mile in Puerto Rico. In Europe the range is from 4 per square mile in Iceland to 831 per square mile in the Netherlands. Within countries there are wide variations of population densities. For example, in Egypt, the average is 55 persons per square mile, but 1,300 persons inhabit each square mile in settled portions where the land is arable. High population densities generally occur in regions of developed industrialization, such as the Netherlands, Belgium, and Great Britain, or where lands are intensively used for agriculture, as in Puerto Rico and Java. Low average population densities are characteristic of most underdeveloped countries. Low density of population is generally associated with a relatively low percentage of cultivated land. This generally results from poor-quality lands. It may also be due to natural obstacles to cultivation, such as deserts, mountains or malaria-infested jungles, to land uses other than cultivation, as pasture and forested land, to primitive methods that limit cultivation, to social obstacles, and to land ownership systems which keep land out of production. More economically advanced countries of low population density have, as a rule, large proportions of their populations living in urban areas. Their rural population densities are usually very low. Poorer developed countries of correspondingly low general population density, on the other hand, often have a concentration of rural population living on arable land, which is as great as the rural concentration found in the most densely populated industrial countries.

单选题The United States is often considered a young nation, but in fact it is next to the oldest continuous government in the world, and the reason is that its people have always been willing to accommodate themselves to change. It should be realized, however, that sharing benefits of our achievements was the result of trial and error. Unprincipled businessmen had first to be restrained by government before they came to learn that they must serve the general good in pursuing their economic interests. Thus, although early statesmen strongly believed in private enterprise, they chose to make the post office a government monopoly and to give the schools to public ownership. Since then, government has broadened its activities in many ways including preventing monopolies from taking over the economy. Increased growth by acquisition by our largest corporations has resulted in a situation where virtually independent economic giants will dominate the American economy. Growth of these vast corporate structures, even though accompanied by an increase in the number of much smaller and less powerful companies that operate under their control, foretells the creation of monopoly — like structures throughout American business. In general, the major acquisitions by the sample companies were corporate organizations that were profitable and successful before acquisition. The main effect of the merger or acquisition was to transfer control and management of an already successful enterprise to a new group. Profitability ratios indicate that, in most instances, the acquired companies operated less efficiently after acquisition. Americans hold with Lincoln that "the legitimate object of government is to do for a community of people whatever they need to have done but cannot do at all, or cannot do so well for themselves, in their separate and individual capacities." Clearly merger restriction is one example of legitimate government intervention.

单选题 Crossing Wesleyan University's campus usually requires walking over colorful messages chalked on the ground. They can be as innocent as meeting announcements, but in a growing number of cases the language is meant to shock. It's not uncommon, for instance, to see lewd references to professors' sexual preferences scrawled across a path or the mention of the word "Nig" that African-American students say make them feel uncomfortable. In response, officials and students at schools are now debating ways to lead their communities away from forms of expression that offend or harass(侵扰). In the process, they're butting up against the difficulties of regulating speech at institutions that pride themselves on fostering open debate. Mr. Bennet of Wesleyan says he had gotten used to seeing occasional chalkings filled with four-letter words. Campus tradition made any horizontal surface not attached to a building a potential billboard. But when chalkings began taking on a more threatening and lewd tone, Bennet decided to act. "This is-not acceptable in a workplace and not acceptable in an institution of higher learning," Bennet says. For now, Bennet is seeking input about what kind of message-posting policy the school should adopt. The student assembly recently passed a resolution saying the "right to speech comes with implicit responsibilities to respect community standards". Other public universities have confronted problems this year while considering various ways of regulating where students can express themselves. At Harvard Law School, the recent controversy was more linked to the academic setting. Minority students there are seeking to curb what they consider harassing speech in the wake of a series of incidents last spring. At a meeting held by the "Committee on Healthy Diversity" last week, the school's Black Law Students Association endorsed a policy targeting discriminatory harassment. It would trigger a review by school officials if there were charges of "severe or pervasive conduct" by students or faculty. The policy would cover harassment based on, but not limited to, factors such as race, religion, creed, sexual orientation, national origin, and ethnicity (种族划分). Boston attorney Harvey Silverglate, says other schools have adopted similar harassment policies that are actually speech codes, punishing students for raising certain ideas. " Restricting students from saying anything that would be. perceived as very unpleasant by another student continues uninterrupted," says Silverglate. who attended the Harvard Law town meeting last week.

单选题{{B}}Passage 2{{/B}} Large, multinational corporations may be the companies whose ups and downs seize headlines. But to a far greater extent than most Americans realize, the economy's vitality depends on the fortunes of tiny shops and restaurants, neighborhood services arid factories. Small businesses, defined as those with fewer than 100 workers, now employ nearly 60 percent of the work force and are expected to generate half of all new jobs between now and the year 2000. Some 1.2 million small firms have opened their doors over the past six years of economic growth, and 1989 will see an additional 200,000 entrepreneurs striking off on their own. Too many of these pioneers, however, will blaze ahead unprepared. Idealists will overestimate the clamor for their products or fail to factor in the competition. Nearly everyone will underestimate, often fatally, the capital that success requires. Midcareer executives, forced by a takeover or a restructuring to quit the corporation and find another way to support themselves, may savor the idea of being their own boss but may forget that entrepreneurs must also, at least for a while, be bookkeeper and receptionist, too. According to Small Business Administration data, 24 of every 100 businesses starting out today are likely to have disappeared in two years, and 27 more will have shut their doors four years from now. By 1995, more than 60 of those 100 start-ups will have folded. A new study of 3,000 small businesses, sponsored by American Express and the National Federation of Independent Business, suggests slightly better odds: Three years after start-up, 77 percent of the companies surveyed were still alive. Most credited their success in large part to having picked a business they already were comfortable in. Eighty percent had worked with the same product or service in their last jobs. Thinking through an enterprise before the launch is obviously critical. But many entrepreneurs forget that a firm's health in its infancy may be little indication of how well it will age. You must tenderly monitor its pulse. In their zeal to expand, small business owners often ignore early warning signs of a stagnant market or of decaying profitability. They hopefully pour more and more money into the enterprise, preferring not to acknowledge eroding profit margins that mean the market for their ingenious service or product has evaporated, or that they must cut the payroll or vacate their lavish offices. Only when the financial well runs dry do they see the seriousness of the illness, and by then the patient is usually too far gone to save. Frequent checks of your firm's vital signs will also guide you to a sensible rate of growth. To snatch opportunity, you must spot the signals that it is time to conquer new markets, add products or perhaps franchise your hot idea.
