单选题At the fall 2001 Social Science History Association convention in Chicago, the Crime and Justice network sponsored a forum on the history of gun ownership, gun use, and gun violence in the United States. Our purpose was to consider how social science history might contribute to the public debate over gun control and gun rights. To date, we have had little impact on that debate. It has been dominated by mainstream social scientists and historians, especially scholars such as Gary Kleck, John Lott, and Michael Bellesiles, whose work, despite profound flaws, is politically congenial to either opponents or proponents of gun control. Kleck and Mark Gertz, for instance, argue on the basis of their widely cited survey that gun owners prevent numerous crimes each year in the United States by using firearms to defend themselves and their property. If their survey respondents are to be believed, American gun owners shot 100, 000 criminals in 1994 in self-defense — a preposterous number. Lott claims on the basis of his statistical analysis of recent crime rates that laws allowing private individuals to carry concealed firearms deter murders, rapes, and robberies, because criminals are afraid to attack potentially armed victims. However, he biases his results by confining his analysis to the year between 1977 and 1992, when violent crime rates had peaked and varied little from year to year. He reports only regression models that support his thesis and neglects to mention that each of those models find a positive relationship between violent crime and real income, and an inverse relationship between violent crime and unemployment. Contrary to Kleck and Lott, Bellesiles insists that guns and America's "gun culture" are responsible for America's high rates of murder. In Belleville's opinion, relatively few Americans owned guns before the 1850s or know how to use, maintain, or repair them. As a result, he says, guns contributed little to the homicide rate, especially among white, which was low everywhere, even in the South and on the frontier, where historians once assume guns and murder went hand in hand. According to Bellesiles, these patterns changed dramatically after the Mexican War and especially after the Civil War, when gun ownership became widespread and cultural changes encouraged the use of handguns to command respect and resolve personal and political disputes. The result was an unprecedented wave of gun-related homicides that never truly abated. To this day, the United States has the highest homicide rate of any industrial democracy. Belleville's low estimates of gun ownership in early America conflict, however, with those of every historian who has previously studied the subject and have thus far proven irreproducible. Every homicide statistic he presents is either misleading or wrong. Given the influence of Kleck, kott, Bellesiles and other partisan scholars on the debate over gun control and gun rights, we felt a need to pull together what social science historians have learned to date about the history of gun ownership and gun violence in America, and to consider what research methods and projects might increase our knowledge in the near future.

单选题{{B}}Passage Four{{/B}} Women earn less than men do. For example, in 1998 the hourly wages of women in the U. S. were 26% less than those of men. The gap between male and female incomes varies with age. The gap between the labor incomes of young women and young men varies. It's also clear that jobs in which women are concentrated pay less. The larger the number of workers who are women in ran industry, the lower the average wages. Why do women earn less than men do? Can the differences be explained by the fact that women are looked down upon? If so, the government has to intervene(干预), to force the employers to pay equal wages to equal jobs. However, there is no agreement among economists about the causes of the gap. One view argues that women, on the average, have chosen low-paying jobs in which workers enjoy the freedom of entering and leaving the labor force, which reduces their years of experience relative to men. Other people say the gap can also be explained by the difference in educational background. Much of the gap, however, has not been fully explained. It might be the result of some prejudice (偏见) against women. It is this part that has produced calls for government action. What would happen if the government did intervene to increase the wages paid to women? One possibility is that incomes for women as a group might actually decline (下降). An increase in wage decreases the quantity of labor imput demanded, resulting in decreased employment as the rate of hiring new workers declines. The result will be a surplus (过剩) of labor. Those who can find jobs might be better off while those who had jobs might find themselves out of work.

单选题Will the European Union make it? The question would have sounded strange not long ago. Now even the project"s greatest cheerleaders talk of a continent facing a "Bermuda triangle" of debt, population decline and lower growth. As well as those chronic problems, the EU faces an acute crisis in its economic core, the 16 countries that use the single currency. Markets have lost faith that the euro zone"s economies, weaker or stronger, will one day converge thanks to the discipline of sharing a single currency, which denies uncompetitive members the quick fix of devaluation. Yet, the debate about how to save Europe"s single currency from disintegration is stuck. It is stuck because the euro zone"s dominant powers, France and Germany, agree on the need for greater harmonization within the euro zone, but disagree about what to harmonize. Germany thinks the euro must be saved by stricter rules on borrowing, spending and competitiveness, backed by quasi-automatic sanctions for governments that do not obey. These might include threats to freeze EU funds for poorer regions and EU mega-projects, and even the suspension of a country"s voting rights in EU ministerial councils. It insists that economic co-ordination should involve all 27 members of the EU club, among whom there is a small majority for free-market liberalism and economic rigor; in the inner core alone, Germany fears, a small majority favour French interference. A "southern" camp headed by France wants something different: "European economic government" within an inner core of euro-zone members. Translated, that means politicians intervening in monetary policy and a system of redistribution from richer to poorer members, via cheaper borrowing for governments through common Eurobonds or complete fiscal transfers. Finally, figures close to the French government have murmured, euro-zone members should agree to some fiscal and social harmonization: e.g. curbing competition in corporate-tax rates or labour costs. It is too soon to write off the EU. It remains the world"s largest trading block. At its best, the European project is remarkably liberal: built around a single market of 27 rich and poor countries, its internal borders are far more open to goods, capital and labour than any comparable trading area. It is an ambitious attempt to blunt the sharpest edges of globalization, and make capital benign.

单选题 The use of deferential(敬重的)language is symbolic of the Confucian ideal of the woman, which dominates conservative gender norms in Japan. This ideal presents a woman who withdraws quietly to the background, subordinating her life and needs to those of her family and its male head. She ii a dutiful daughter, wife, and mother, master of the domestic arts. The typical refined Japanese woman excels in modesty and delicacy; she "treads softly (谨言慎行)in the world", elevating feminine beauty and grace to an art form. Nowadays, it is commonly observed that young women are not conforming to the feminine linguistic(语言的) ideal. They are using fewer of the very deferential "women's" forms, and even using the few strong forms that are known as "men's". This, of course, attracts considerable attention and has Led to an outcry in the Japanese media against the defeminization of women's language. Indeed, we didn't hear about "men's language" until people began to respond to girls' appropriation of forms normally reserved for boys and men. There is considerable sentiment about the "corruption" of women's language-which of course is viewed as part of the loss of feminine ideals and morality--and this sentiment is crystallized by nationwide opinion polls that are regularly carried out by the media. Yoshiko Matsumoto has argued that young women probably never used as many of the highly deferential forms as older women. This highly polite style is no doubt something that young women have been expected to "grow into"--after all, it is a sign simply of femininity, but of maturity and refit, and its use could be taken to indicate a change in the nature of one's social relations as well. one might well imagine little girls using exceedingly polite forms when playing house or imitating older women--in a fashion analogous to little girls' use of a high-pitched voice to do "teacher talk" or "mother talk" in rote play. The fact that young Japanese women are using less deferential language is a sure sign of change--of social change and of linguistic change. But it is most certainly not a sign of the "masculinization" of girls. In some instances, it may be a sign that girls are making the same claim to authority as boys and men, but that is very different from saying that they are trying to be "masculine". Katsue Reynolds has argued that girls nowadays are using mole assertive language strategies in order to be able to compete with boys in schools and out. Social change also brings not simply different positions for women and girls, but different relations to life stages, and adolescent girls file participating in new subcultural forms. Thus what may, to an older speaker, seem like "masculine" speech may seem to an adolescent like "liberated" or "hip" speech.
