单选题The work of English writer Aphra Behn (1640 ~ 1689) changed markedly during the 1680s, as she turned from writing plays to writing prose narratives. According to literary critic Rachel Carnell, most scholars view this change as primarily motivated by financial considerations: earning a living by writing for the theatre became more difficult in the 1680s, so Behn tried various other types of prose genres in the hope of finding another lucrative medium. In fact, a long epistolary scandal novel that she wrote in the mid-1680s sold quite well. Yet, as Carnell notes, Behn did not repeat this approach in her other prose works; instead, she turned to writing shorter, more serious novels, even though only about half of these were published during her lifetime. Carnell argues that Behn, whose stage productions are primarily comedies, may have turned to an emerging literary form, the novel, in a conscious attempt to criticize, and subvert for her own ends, the conventions and ideology of a well-established form of her day, the dramatic tragedy. Carnell acknowledges that Behn admired the skill of such contemporary writers of dramatic tragedy as John Dryden, and that Behn's own comic stage productions displayed the same partisanship for the reigning Stuart monarchy that characterized most of the politically oriented dramatic tragedies of her day. However, Carnell argues that Behn took issue with the way in which these writers and plays defined the nature of tragedy. As prescribed by Dryden, tragedy was supposed to concern a heroic man who is a public figure and who undergoes a fall that evokes pity from the audience. Carnell points out that Behn's tragic novels focus instead on the plight of little-known women and the private world of the household; even in her few novels featuring male protagonists, Behn insists on the importance of the crimes these otherwise heroic figures commit in the domestic sphere. Moreover, according to Carnell, Behn questioned the view promulgated by monarchist dramatic tragedies such as Dryden's; that the envisioned "public" political ideal — passive obedience to the nation's king — ought to be mirrored in the private sphere, with family members wholly obedient to a male head of household. Carnell sees Behn's novels not only as rejecting the model of patriarchal and hierarchical family order , but also as warning that insisting on such a parallel can result in real tragedy befalling the members of the domestic sphere. According to Carnell, Behn's choice of literary form underscores the differences between her own approach to crafting a tragic story and that taken in the dramatic tragedies, with their artificial distinction between the public and private spheres. Behn's novels engage in the political dialogue of her era by demonstrating that the good of the nation ultimately encompasses more than the good of the public figures who rule it.

单选题This is not a good time to be foreign. Anti-immigrant parties are gaining ground in Europe. Britain has been fretting this week over lapses in its border controls. In America Barack Obama has failed to deliver the immigration reform he promised, and Republican presidential candidates would rather electrify the border fence with Mexico than educate the children of illegal aliens. America educates foreign scientists in its universities and then expels them, a policy the mayor of New York calls "national suicide". This illiberal turn in attitudes to migration is no surprise. It is the result of cyclical economic gloom combined with a secular rise in pressure on rich countries" borders. But governments now weighing up whether or not to try to slam the door should consider another factor; the growing economic importance of Diasporas, and the contribution they can make to a country"s economic growth. Diaspora networks—of Huguenots, Scots, Jews and many others—have always been a potent economic force, but the cheapness and ease of modern travel has made them larger and more numerous than ever before. There are now 215m first-generation migrants around the world: that"s 3% of the world"s population. If they were a nation, it would be a little larger than Brazil. There are more Chinese people living outside China than there are French people in France. Some 22m Indians are scattered all over the globe. Small concentrations of ethnic and linguistic groups have always been found in surprising places—Lebanese in West Africa, Japanese in Brazil and Welsh in Patagonia , for instance—but they have been joined by newer ones, such as west Africans in southern China. These networks of kinship and language make it easier to do business across borders. Theyspeed the flow of information. Trust matters, especially in emerging markets where the rule of law is weak. So does a knowledge of the local culture. And modern communications make these networks an even more powerful tool of business. Diasporas also help spread ideas. Many of the emerging world"s brightest minds are educated at Western universities. An increasing number go home, taking with them both knowledge and contacts. Indian computer scientists in Bangalore bounce ideas constantly off their Indian friends in Silicon Valley. China"s technology industry is dominated by "sea turtles" (Chinese who have lived a-broad and returned). Diasporas spread money, too. Migrants into rich countries not only send cash to their families; they also help companies in their host country operate in their home country. A Harvard Business School study shows that, American companies that employ lots of ethnic Chinese people find it much easier to set up in China without a joint venture with a local firm. Such arguments are unlikely to make much headway against hostility towards immigrants in rich countries. Fury against foreigners is usually based on two (mutually incompatible) notions; that because so many migrants claim welfare they are a drain on the public purse; and that because they are prepared to work harder for less pay they will depress the wages of those at the bottom of the pile. The first is usually not true (in Britain, for instance, immigrants claim benefits less than indigenous people do) , and the second is hard to establish either way. Some studies do indeed suggest that competition from unskilled immigrants depresses the wages of unskilled locals. But others find this effect to be small or non-existent. Nor is it possible to establish the impact of migration on overall growth. The sums are simply too difficult. Yet there are good reasons for believing that it is likely to be positive. Migrants tend to be hard-working and innovative. That spurs productivity and company formation. A recent study carried out by Duke University showed that, while immigrants make up an eighth of America"s population , they founded a quarter of the country"s technology and engineering firms. And, by linking the West with emerging markets, Diasporas help rich countries to plug into fast-growing economies. Rich countries are thus likely to benefit from looser immigration policy; and fears that poor countries will suffer as a result of a "brain drain" are overblown. The prospect of working abroad spurs more people to acquire valuable skills, and not all subsequently emigrate. Skilled migrants send money home, and they often return to set up new businesses. One study found that unless they lose more than 20% of their university graduates, the brain drain makes poor countries richer.

单选题Passage 1 Many United States companies have, unfortunately, made the search for legal protection from import competition into a major line of work. Since 1980 the United States international Trade Commission (ITC) has received about 280 complaints alleging damage from imports that benefit from subsidies by foreign governments. Another 340 charge that foreign companies "dumped" their products in the United States at "less than fair value. " Even when no unfair practices are alleged, the simple claim that an industry has been injured by imports is sufficient grounds to seek relief. Contrary to the general impression, this quest for import relief has hurt more companies than it has helped. As corporations begin to function globally, they develop an intricate web of marketing, production, and research relationships. The complexity of these relationships makes it unlikely that a system of import relief laws will meet the strategic needs of all the units under the same parent company. Suppose a United States-owned company establishes an overseas plant to manufacture a product while its competitor makes the same product in the United States. If the competitor can prove injury from the imports—and that the United States company received a subsidy from a foreign government to build its plant abroad—the United States company's products will be uncompetitive in the United States, since they would be subject to duties. Perhaps the most brazen ease occurred when the ITC investigated allegations that Canadian companies were injuring the United States salt industry by dumping rock salt, used to de-ice roads. The bizarre aspect of the complaint was that a foreign conglomerate with" United States operations was crying for help against a United States company with foreign operations. The "United States" company claiming injury was a subsidiary of a Dutch conglomerate, while the "Canadian" companies included a subsidiary of a Chicago firm that was the second-largest domestic producer of rock salt.
