单选题 The Magic of Diasporas(大移居) Immigrant networks are a rare bright spark in the world economy. Rich countries should welcome them. A．This is not a good time to be foreign. Anti-immigrant parties are gaining ground in Europe. Britain has been fretting(烦 恼，发愁) this week over lapses in its border controls. In America Barack Obama has failed to deliver the immi-gration 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'. B．This illiberal turn in attitudes to migration is no surprise. It is the result of cyclical economic gloom combined with a 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. C．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. D．These networks of kinship(亲缘关系) and language make it easier to do business across borders. They speed the flow of information: a Chinese trader in Indonesia who spots a gap in the market for cheap umbrellas will alert his cousin in Shenzhen who knows someone who runs an umbrella factory. Kinship ties foster trust, so they can seal the deal and get the umbrellas to Jakarta before the rainy season ends. Trust matters, especially in emerging markets where the rule of law is weak. So does the knowledge of the local culture. That is why so much foreign direct investment in China still passes through the Chinese diasporas. And modern communications make these networks an even more powerful tool of business. E．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 abroad and returned). F．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. G．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 local people do), and the second is hard to establish either way. Some studies do indeed suggest that competition from unskilled immigrants depresses the wages ofunskilled locals. But others find this effect to be small or non-existent. H．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. I．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. J．Government as well as business gains from the spread of ideas through diasporas. Foreign-educated Indians, including the Prime Minister, Manmohan Singh (Oxford and Cambridge) and his sidekick Montek Ahluwalia (Oxford), played a big role in bringing economic reform to India in the early 1990s. Some 500,000 Chinese people have studied abroad and returned, mostly in the past decade; they dominate the think-tanks that advise the government. K．As for the old world, its desire to close its borders is understandable but dangerous. Migration brings youth to ageing countries, and allows ideas to circulate in millions of mobile minds. That is good both for those who arrive with suitcases and dreams and for those who should welcome them.

单选题 When you see a corporate scoundrel go unpunished, or a puppy die of cancer, or Rashida Jones gifted with talent, beauty, and smarts, you might be forgiven for asking: Is life fair? And yet most of us cling to the idea that people generally get what they deserve. Our belief in the world's fairness can veer into magical thinking. For example, one study found that people who frequently patronize a business believe they are more likely than other customers to win a given prize drawing by that business—a phenomenon the researchers called the 'lucky loyalty' effect. A similar logic leads people to invest in karma. In one experiment, people at a job fair who were led to think that the job-search process was beyond their control offered to donate more money to an unrelated charity than did those who were led to believe the opposite. In a follow-up study, job seekers who were encouraged to see their job search as beyond their control were more optimistic about their employment prospects when they gave money to charity than when they didn't. Faith in fairness does have a dark side. One study found that women who believe strongly that the world is fair are more likely than other women to blame the victim of a hypothetical stranger rape. And people who believe in a just world are less likely to hire a job candidate who's been laid off. When bad things happen to good people, we sometimes convince ourselves that the bad things are in fact good things—blessings in disguise. After people's appetite for justice was deliberately stoked, they tended to see a 30-year-old who had suffered a debilitating accident in childhood as enjoying a more meaningful life than one who hadn't. Such thoughts may ease the pain associated with injustice, and even lead to support for the status quo: Researchers found that when people felt powerless, they were more likely to say that race, class, and gender disparities were justified. Certain social institutions and ideologies, including religion and political conservatism, may further increase our complacence. In a series of surveys, respondents' religiosity correlated with belief in a just world, belief that capitalism is fair, social and economic conservatism, acceptance of income inequality, and belief in the fairness of the American social system.
