单选题What does "them" in tile last line of Paragraph 2 refer to?

单选题 Questions 62 to 66 are based on the following passage. Under the gold standard, paper money was backed by gold reserves. If gold flowed into a country, its money and credit supply were supposed to expand. If gold flowed out, money and credit were supposed to contract. During World War I, Europe's governments suspended the gold standard. They financed the war with paper money and loans from America. The appeal of restoring the gold standard was that it would instill confidence by making paper money trustworthy. Unfortunately, the war damaged the system beyond repair. Britain, the key country, was left with only 7. 5 of the world's gold reserves in 1925. Together, the United States and France held more than half the world's gold. The war had expanded U. S. reserves, and when France returned to gold, it did so with an undervalued exchange rate that boosted exports and gold reserves. Meanwhile, German reparations (赔款) to Britain and France were massive, while those countries owed huge amounts to the United States. The global financial system was so debt-laden that it "cracked at the first pressure. " That came after a rise in American interest rates in 1928 forced other countries to follow and ultimately led to the 1929 stock market crash. As economies weakened, debts went into default. Bank panics ensued. Credit and industrial production declined. Unemployment rose. Weakness fed on weakness. Sadly, this tragedy has modern parallels. Like the 1930s, a worldwide credit collapse is a danger. Global stock, bond and bank markets are interwoven. Losses in one may prompt pullbacks in others. Money that flows to 28 "emerging market" countries in 2009 will drop 80 percent from 2007 levels. Currency misalignments have, as in the 1920s, distorted trade. China's Renminbi is clearly undervalued. Still, striking differences separate now from then. The biggest is that governments--unencumbered by the gold standard--have eased credit, propped up financial institutions and increased spending to arrest an economic free fall. The Federal Reserve and the International Monetary Fund have made loans available to emerging market countries to offset the loss of private credit. Nor is there anything like the international rancor (怨恨) that followed World War I and impeded (妨碍) cooperation: in 1931, the French balked at (回避) rescuing Austria's biggest bank (Credit Anstalt), whose failure triggered a chain reaction of European panics. When countries left the gold standard--the United States effectively did so in 1933--their economies began to recover. Some indicators now imply that the present decline is ebbing. China shows similar signs of improvement.

单选题Forget Brother, Can You Spare a Dime? The theme song of this recession might well be "Mother, Can You Write a Check?" The distressing economy has resulted in increasing numbers of parents and grandparents helping out their strapped adult children and grandldds with home down payments, credit-card bailouts(紧急救助), and spare cash--often at the same time as parents are trying to confront new retirement budgets. "We are seeing a ton of this," says Ross Levin, a financial adviser. "Sometimes it's a great idea and sometimes it is not. You have to make sure you put on your own oxygen mask first. " Some 62 percent of visitors to Grandparents. com have helped their kids financially in the past year, with 70 percent of that group handing over cash to help their adult children and grandchildren with dally expenses, says the site's CEO, Jerry Shereshewsky. Another popular category is housing ; in the last year many parents have coughed up down payments to help their kids get into homes while the $ 8 000 first-time home buyer's credit was in effect. Then there's the debt-bailout situation. A survey recently conducted by Creditcards. com for Newsweek found that 42 percent of folks with adult children have helped them pay off car loans, credit cards, medical bills, and more. None of this is surprising to Shereshewsky, who sees the trend as a natural result of changing families and the distribution of wealth. "This is where all the money is--and it's where the money is, despite the fact that we've had this meltdown. '" In general, the baby-boom generation is far wealthier than their children are, and has a lower unemployment rate than 20-somethings. He says that the vast majority of multi-generation households now involve adult children ( and sometimes their children) moving in with aging parents. Baby-boom parents generally aspire to helping their kids and their grandchildren and don't want to walt until they are dead to do it. "You should give while you're young enough to enjoy the fruits of what you're doing," says Shereshewsky, who is personally considering getting a reverse mortgage on his home when it comes time to help his. 20-something kids with home purchases.

单选题As regards social conventions, we must say a word about the well-known English class system. This is an embarrassing subject for English people, and one they tend to be ashamed of, though during the present century class-consciousness has grown less and less, and the class system less rigid. But it still exists below the surface. Broadly speaking, it means there are two classes, the "middle class" and the "working class". (We shall ignore for a moment the old "upper class", including the hereditary aristocracy, since it is extremely small in numbers; but some of its members have the right to sit in the House of Lords, and some newspapers take a surprising interest in their private life.) The middle class consists chiefly of well-to-do businessmen and professional people of all kinds. The working class consists chiefly of manual and unskilled workers. The most obvious difference between them is in their accent. Middle-class people use slightly varying kinds of "received pronunciation" which is the kind of English spoken by BBC announcers and taught to overseas pupils. Typical working-class people speak in many different local accents which are generally felt to be rather ugly and uneducated. One of the biggest barriers of social equality in England is the two-class education system. To have been to a so-called "public school" immediately marks you out as one of the middle class. The middle classes tend to live a more formal life than working-class people, and are usually more cultured. Their midday meal is "lunch" and they have a rather formal evening meal called "dinner", whereas the working man's dinner, if his working hours permit, is at midday, and his smaller, late-evening meal is called supper. As we have said, however, the class system is much less rigid than it was, and for a long time it has been government policy to reduce class distinctions. Working-class students very commonly receive a university education and enter the professions, and working-class incomes have grown so much recently that the distinctions between the two classes are become less and less clear. However, regardless of one's social status, certain standards of politeness are expected of everybody, and a well-bred person is polite to everyone he meets, and treats a labourer with the same respect he gives an important businessman. Servility inspires both embarrassment and dislike. Even the word "sir", except in schools and in certain occupations (e. g. commerce, the army etc.) sounds too servile to be commonly used.

单选题A new partner pushes out two close friends on average, leaving lovers with a smaller inner circle of people they can turn to in times of crisis, a study found. The research, led by Robin Dunbar, head of the Institute of Cognitive (认知的) and Evolutionary Anthropology (人类学) at Oxford University, showed that men and women were equally likely to lose their closest friends when they started a new relationship. Previous research by Dunbar"s group has shown that people typically have five very close relationships—that is, people whom they would turn to if they were in emotional or financial trouble. "If you go into a romantic relationship, it costs you two friends. Those who have romantic relation- ships, instead of having the typical five "core set" of relationships only have four. And of those, one is the new person who"s come into their life," said Dunbar. The study, submitted to the journal Personal Relationships, was designed to investigate how people trade off spending time with one person over another and suggests that links with fancily and closest friends suffer when people start a romantic relationship. Dunbar"s team used an internet-based questionnaire to quiz 428 women and 112 men about their relationships. In total, 363 of the participants had romantic partners. The findings suggest that a new love interest has to compensate for the loss of two close friends. Speaking at the British Science Festival, Professor Dunbar said: "This was a surprise for us. We hadn"t expected it." "What I suspect is that your attention is so wholly focused on the romantic partner you don"t get to see the other folks you had a lot to do with before, and so some of those relationships start to deteriorate (变糟)." The questionnaire allowed people to mention whether any of their closest friends were "extra romantic partners". In all, 32 of those quizzed mentioned having an extra love interest in their life, but these people did not lose four friends as might be expected. Instead, the extra person in their life bumped their original romantic partner out of their innermost circle of friends.
