单选题Sleep is a funny thing. We' re taught that we should get seven or eight hours a night, but a lot of us get by just fine on less, and some of us actually sleep too much. A study out of the University of Buffalo last month reported that people who routinely sleep more than eight hours a day and are still tired are nearly three times as likely to die of stroke—probably as a result of an underlying disorder that keeps them from snoozing soundly. Doctors have their own special sleep problems. Residents are famously sleep deprived. When I was training to become a doctor, it was not unusual to work 40 hours in a row without rest. Most of us took it in stride, confident we could still deliver the highest quality of medical care. Maybe we shouldn't have been so sure of ourselves. An article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person' s motor performance is comparable to that of someone who is legally intoxicated. Curiously, surgeons who believe that operating under the influence is grounds for dismissal often don't think twice about operating without enough sleep. "I could tell you horror stories, ' says Jaya Agrawal, president of the American Medical Student Association, which runs a website where residents can post anonymous anecdotes. Some are terrifying. "I was operating after being up for over 36 hours," one writes. "I literally fell asleep standing up and nearly face planted into the wound." "Practically every surgical resident I know has fallen asleep at the wheel driving home from work, "writes another. "I know of three who have hit parked cars. Another hit a convenience store on the roadside, going [1051an/h]." "Your own patients have become the enemy," writes a third," because they are the one thing that stands between you and a few hours of sleep." Agrawal' s organization is supporting the Patient and Physician Safety and Protection Act of 2001, introduced last November by Representative John Conyers Jr. of Michigan. Its key provisions, modeled on New York State' s regulations, include an 80-hour workweek and a 24hour work-shift limit. Most doctors, however, resist such interference. Dr. Charles Binkley, a senior surgery resident at the University of Michigan, agrees that something needs to be done but believes" doctors should be bound by their conscience, not by the government." The U. S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own. If you're worried about the people treating you, you should feel free to ask how many hours of sleep they have had. Doctors, for their part, have to give up their pose of infallibility and get the rest they need.

单选题{{B}}Text 4{{/B}} In 1880, Sir Joshua Waddilove, a Victorian philanthropist, founded Provident Financial to provide affordable loans to working-class families in and around Bradford, in northern England. This month his company, now one of Britain's leading providers of "home credit" -small, short-term, unsecured loans—began the nationwide rollout of Vanquis, a credit card aimed at people that mainstream lenders shun. The card offers up to they impose extra charges, such as application fees; and they cap their potential losses by lending only small amounts ( $ 500 is a typical credit limit). All this is easier to describe than to do, especially when the economy slows. After the bursting of the technology bubble in 2000, several sub-prime credit-card providers failed. Now there are only around 100, of which nine issue credit cards. Survivors such as Metris and Providian, two of the bigger sub-prime card companies, have become choosier about their customers' credit histories. As the economy recovered, so did lenders' fortunes. Fitch, a rating agency, says that the proportion of sub-prime credit-card borrowers who are more than 60 days in arrears (a good predictor of eventual default)is the lowest since November 2001. But with American interest rates rising again, some worry about another squeeze. As Fitch's Michael Dean points out, sub-prime borrowers tend to have not just higher-rate credit cards, but dearer auto loans and variable-rate mortgages as well That makes a risky business even riskier.

单选题 "The impulse to excess among young Britons remains as powerful as ever, but the force that used to keep the impulse in check has all but disappeared," claimed a newspaper. Legislation that made it easier to get hold of a drink was "an Act for the increase of drunkenness and immorality", asserted a politician. The first statement comes from 2005, {{U}}the second{{/U}} from 1830. On both occasions, the object of scorn was a parliamentary bill that promised to sweep away " antiquated" licensing laws. As liberal regulations came into force this week, Britons on both sides of the debate unwittingly followed a 19th-century script. Reformers then, as now, took a benign view of human nature. Make booze cheaper and more readily available, said the liberalisers, and drinkers would develop sensible, continental European-style ways. Nonsense, retorted the critics. Habits are hard to change; if Britons can drink easily, they will drink more. Worryingly for modern advocates of liberalisation, earlier doomsayers turned out to be right. Between 1820 and 1840, consumption of malt (which is used to make beer) increased by more than 50%. Worse, Britons developed a keener taste for what Thomas Carlyle called "liquid madness"—gin and other spirits. The backlash was fierce. Critics pointed to widespread debauchery in the more disreputable sections of the working class. They were particularly worried about the people who, in a later age, came to be known as "ladettes". An acute fear, says Virginia Berridge, who studies temperance at the London School of Hygiene and Tropical Medicine, was that women would pass on their sinful ways to their children. In the 19th century, temperance organisations set up their own newspapers to educate the public about the consequences of excess. That, at least, has changed: these days, the mainstream media rail against the demon drink all by themselves.

单选题{{B}}Text 2{{/B}} It is no longer just dirty blue-collar jobs in manufacturing that are being sucked offshore but also white-collar service jobs, which used to be considered safe from foreign competition. Telecoms charges have tumbled, allowing workers in far-flung locations to be connected cheaply to customers in the developed world. This has made it possible to offshore services that were once non-tradable. Morgan Stanley's Mr. Roach has been drawing attention to the fact that the "global labour arbitrage" is moving rapidly to the better kinds of jobs. It is no longer just basic data processing and call centres that are being outsourced to low-wage countries, but also software programming, medical diagnostics, engineering design, law, accounting, finance and business consulting. These can now be delivered electronically from anywhere in the world, exposing skilled white-collar workers to greater competition. The standard retort to such arguments is that outsourcing abroad is too small to matter much. So far fewer than lm American service-sector jobs have been lost to off-shoring. Forrester Research forecasts that by 2015 a total of 3.4m jobs in services will have moved abroad, but that is tiny compared with the 30m jobs destroyed and created in America every year. The trouble is that such studies allow only for the sorts of jobs that are already being off-shored, when in reality the proportion of jobs that can be moved will rise as IT advances and education improves in emerging economies. Alan Blinder, an economist at Princeton University, believes that most economists are underestimating the disruptive effects of off-shoring, and that in future two to three times as many service jobs will be susceptible to off-shoring as in manufacturing. This would imply that at least 30% of all jobs might be at risk. In practice the number of jobs off-shored to China or India is likely to remain fairly modest. Even so, the mere threat that they could be shifted will depress wages. Moreover, says Mr. Blinder, education offers no protection. Highly skilled accountants, radiologists or computer programmers now have to compete with electronically delivered competition from abroad, whereas humble taxi drivers, janitors and crane operators remain safe from off-shoring. This may help to explain why the real median wage of American graduates has fallen by 6% since 9000, a bigger decline than in average wages. In the 1980s and early 1990s, the pay gap between low-paid, low-skilled workers and high-paid, high-skilled Workers widened significantly. But since then, according to a study by David Autor, Lawrence Katz and Melissa Kearney, in America, Britain and Germany workers at the bottom as well as at the top have done better than those in the middle-income group. Office cleaning cannot be done by workers in India. It is the easily standardised skilled jobs in the middle, such as accounting, that are now being squeezed hardest. A study by Bradford Jensen and Lori Kletzer, at the Institute for International Economics in Washington D. C., confirms that workers in tradable services that are exposed to foreign competition tend to be more skilled than workers in non-tradable services and tradable manufacturing industries.

单选题For the first time, George Bush has acknowledged the existence of secret CIA prisons around the world, where key terrorist suspects—100 in all, officials say--have been interrogated with "an alternative set of procedures". Fourteen of the suspects, including the alleged mastermind of the September 11th attacks, were transferred on Monday to the American naval base at Guantanamo Bay in Cuba, where some will face trial for war crimes before special military commissions. Many of these men--as Mr. Bush confirmed in a televised speech at the White House on September 6th--are al-Qaeda operatives or Taliban fighters who had sought to withhold information that could "save American lives". "In these cases, it has been necessary to move these individuals to an environment where they can be held secretly (and) questioned by experts," the president said. He declined to say where they had been held or why they had not simply been sent straight to Guantanamo, as some 770 other suspected terrorists have been. Mr. Bush also refused to reveal what interrogation methods had been used, saying only that, though "tough", they had been "safe and lawful and necessary". Many believe that the main purpose of the CIA's prisons was to hide from prying eyes the torture and other cruel or degrading treatment used to extract information from prisoners. But Mr. Bush insisted that America did not torture: "It's against our laws, and it's against our values. I have not authorised it and I will not authorise it." The pentagon this week issued its long-awaited new Army Field Manual, forbidding all forms of torture and degrading treatment of prisoners by army personnel--though not the CIA. For the first time, it specifically bans forced nakedness, hooding, the Use of dogs, sexual humiliation and "waterboarding" (simulated drowning)--all practices that have been used at Guantanamo and Abu Ghraib. So why did the president decide now to reveal the CIA's secret programme? Partly, he confessed; because of the Supreme Court's recent ruling that minimum protections under the Geneva Conventions applied to all military prisoners, no matter where they were. This has put American agents at risk of prosecution for war crimes. Mr. Bush has now asked Congress to ban suspected terrorists from suing American personnel in federal courts.

单选题Which statement is NOT true according to par

单选题{{B}}Text 2{{/B}} "The essential qualities of a true Pan-Americanism", remarked Franklin Roosevelt in 1933, "must be the same as those which constitute a good neighbour, namely mutual understanding and... a sympathetic appreciation of the other's point of view." That is advice which the United States would do well to heed in its relations with its immediate neighbours, Canada and Mexico. Most Americans may not be aware of it, but frustrations and resentments are building just across their borders to both south and north. Of course, neighbourly ties in North America are closer than in Roosevelt's day. Under the North American Free-Trade Agreement (NAFTA), trade among the three countries has more than doubled since 1994 and cross-border investment climbed even faster. In the aftermath of the terrorist attacks of September 11th 2001, the United States moved quickly to sign "smart border" agreements with both Canada and Mexico, to try to ensure that the demands of security did not interrupt trade. By the standards of much of the 20th century, political ties between the United States and Mexico are warm. Yet go to either border and you wouldn't know all this. Fed up with the flow of illegal migrants from thc south, the governors of Arizona and New Mexico this month declared a state of emergency. Violence between drug gangs recently led the United States temporarily to close its consulate in Nuevo Laredo, the busiest border-crossing point. The American ambassador bluntly criticises Mexico for its failure to prevent drug-related violence along the border. That has prompted retaliatory verbal blasts from Mexican officials. Canada's mood is not much more cordial. Since September 11th, Canadians and Americans alike have become less keen on popping over what they liked to call "the world's longest undefended border" for shopping or recreation. Canadians increasingly disagree with Americans over matters as varied as the Iraq war and gay marriage. They are disillusioned with NAFTA, claiming it has failed to prevent the United States from unlawfully punishing their exports of, for example, lumber. So what? Friction is in the nature of international relations, and the problems on the northern border are different from those in the south. Yet there is a common denominator. Americans tend to see security, migration, drugs, even trade, as domestic political issues. But so they are for Canada and Mexico too. Like it or not, Americans rely on their neighbours for prosperity, energy and help with security. It behoves all three countries to show some "sympathetic understanding".

单选题{{B}}Text 4{{/B}} Scores of workers from MTV Networks walked off the job yesterday afternoon, filling the sidewalk outside the headquarters of its corporate parent, Viacom, to protest recent changes in benefits. The walkout highlighted the concerns of a category of workers who are sometimes called permalancers: permanent freelancers who work like full-time employees but do not receive the same benefits. Waving signs that read "Shame on Viacom," the workers, most of them in their 20s, demanded that MTV Networks reverse a plan to reduce health and dental benefits for freelancers beginning On Jan. 1st. In a statement, MTV Networks noted that its benefits program for full-time employees had also undergone changes, and it emphasized that the plan for freelancers was still highly competitive within the industry. Many freelancers receive no corporate benefits. But some of the protesters asserted that corporations were competing to see which could provide the most mediocre health care coverage. Matthew Yonda, who works at Nickelodeon, held a sign that labeled the network "Sick-elodeon. " "I've worked here every day for three years-I'm not a freelancer," Mr. Yonda said. "They just call us freelancers in order to bar us from getting the same benefits as employees. " The changes to the benefits package were announced last Tuesday. Freelancers were told that they would become eligible for benefits after 160 days of work, beginning in January. While that eased previous eligibility rules, which required freelancers to work for 52 weeks before becoming eligible, it would have required all freelancers not yet eligible for benefits to start the waiting period over again on Jan. 1st. The 401 (k) plan was also removed. On Thursday, acknowledging the complaints, MTV Networks reinstated the 401 (k) plan and said freelancers who had worked consistently since March would be eligible. Fueled by a series of blog posts on the media Web site Gawker-the first post was headlined "The Viacom Permalance Slave System"-a loose cohort of freelancers created protest stickers and distributed walkout fliers last week. Caroline O'Hare, a unit manager who has worked for MTV for more than two years, said the new health care plan-with higher deductibles and a $ 2,000 cap on hospital expenses each year-had provoked outrage. "They think they can treat us like children that don't have families, mortgages or dreams of retirement," she said. Outside Viacom's headquarters, several workers held posters with the words, "There's too many of us to ignore. " It was unclear how many freelancers are on the company's payroll; an MTV Networks' spokeswoman said the figure was not known because it rises and falls throughout the year. The company has 5,500 full-time employees, excluding freelancers, around the world. Two freelancers and one full-time employee, who asked not to be identified for fear of retribution, estimated that the percentage of freelancers in some departments exceeded 75 percent. Another labor action is expected to take place outside Viacom later this week. Members of the Writers Guild of America, who have been on strike for five weeks, are expected to picket there on Thursday.
