The ambitious attempt to compare happiness levels around the world is based on the principle that wealth is not the only measure of human satisfaction and well-being. The index of 111 countries uses data on incomes, health, unemployment, climate, political stability, job security, gender equality as well as what the magazine calls "freedom, family and community life". Despite the bad weather, troubled health service, traffic congestion (拥挤), gender inequality, and the high cost of living, Ireland scored an impressive 8.33 points out of 10. That put it well ahead of second-place Switzerland, which managed 8.07. Zimbabwe, troubled by political insecurity and hunger, is rated the gloomiest (最差的), picking up only 3.89 points. "Although rising incomes and increased individual choices are highly valued," the report said, "some of the factors associated with modernization such as the breakdown (崩溃) in traditional institutions and family values in part take away from a positive impact." "Ireland .wins because it successfully combines the most desirable elements of the new with the preservation of certain warm elements of the old, such as stable family and community life." The magazine admitted measuring quality of life is net a straightforward thing to do, and that its findings would have their critics. No. 2 on the list is Switzerland. The other nations in the top 10 are Norway, Luxembourg, Sweden, Australia, Iceland, Italy, Denmark and Spain. The UK is positioned at No. 29, a much lower position chiefly because of the social and family breakdown recorded in official statistics. The US, which has the second highest per capita GDP (人均国内生产总值) after Luxembourg, took the 13th place in the survey. China was in the lower half of the league at 60th.

单选题Eat More, Weigh Less, Live Longer Clever genetic detective work may have found out the reason why a near-starvation diet prolongs the life of many animals. Ronald Kahn at Harvard Medical School in Boston, US, and his colleagues have been able to extend the lifespan (寿命) of mice by 18 percent by blocking the rodent's (啮齿动物) increase of fat in specific cells. This suggests that thinness—and not necessarily diet— promotes long life in "calorie (热量单位, 卡) restricted" animals. "It's very cool work, "says aging researcher Cynthia Kenyon of the University of California, San Francisco. "These mice eat all they want, lose weight and live longer. It's like heaven." Calorie restriction dramatically extends the lifespan of organisms as different as worms and rodents. Whether this works in humans is still unknown, partly because few people are willing to submit to such a strict diet. But many researchers hope they will be able to trigger the same effect with a drug once they understand how less food leads to a longer life. One theory is that eating less reduces the increase of harmful things that can damage cells. But Kahn's team wondered whether the animals simply benefit by becoming thin. To find out, they used biology tricks to disrupt the insulin (胰岛素) receptor (受体) gene in lab mice—but only in their fat cells. "Since insulin is needed to help fat ceils store fat, these animals were protected against becoming fat," explains Kahn. This slight genetic change in a single tissue had dramatic effects. By three months of age, Kahn's modified mice had up to 70 percent less body fat than normal control mice, despite the fact that they ate 55 percent more food per gram of body weight. In addition, their lifespan increased. The average control mouse lived 753 days, while the thin rodents averaged a lifespan of 887 days. After three years, all the control mice had died, but one-quarter of the modified rodents were still alive. "That they get these effects by just manipulating the fat cells is controversial," says Leonard Guarente of the Massachusetts Institute of Technology, who studies calorie restriction and aging. But Guarente says Kahn has yet to prove that the same effect is responsible for increased lifespan in calorie-restricted animals. "It might be the same effect or there might be two routes to long life," he points out, "and that would be very interesting./

单选题New Foods and the New World In the last 500 years, nothing about people—not their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree (可可树) by South American Indians. The Spanish introduced it to the rest of the world during the 1500"s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today. The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the "Potato Famine (饥荒)" of 1845-1846, and thousands more were forced to leave their homeland and move to America. There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world"s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400"s. According to an Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and experienced the "wide-awake" feeling that one-third of the world"s population now starts the day with.

单选题{{B}}第二篇{{/B}} Milosevie's Death Former Yugoslav leader Slobodan Milosevic was found dead last Saturday in his cell at the Hague-based International Criminal Tribunal for the former Yugoslavia. The 64-year-old had been on trial there since February 2002. Born in provincial Pozarevac in 1941, he was the second son of a priest and a school teacher, Both of his parents died when he was still a young adult. The young Milosevic was "untypical", says Slavoljub Djukic, his unofficial biographer. He was "not interested in sports, avoided excursions (短途旅行) and used to come to school dressed in the old-fashioned way-white shirt and tie. " One of his old friends said, he could "imagine him as a station-master or punctilious (一丝不苟的) civil servant. Indeed that is exactly what he might have become, had he not married Mira. She was widely believed to be his driving force. At university and beyond he did well. He worked for various firms and was a communist party member. By 1986 he was head of Serbia's Central Committee. But still he had not yet really been noticed. It was Kosovo that gave him his chance. An autonomous province of Serbia, Kosovo was home to an Albanian majority and a Serbian minority. In 1989, he was sent there to calm fears of Serbians who felt they were discriminated against. But instead he played the nationalist card and became their champion. In so doing, he changed into a ruthless (无情的) and determined man. At home with Mira he plotted the downfall of his political enemies. Conspiring(密谋) with the director of Serbian TV, he mounted a modern media campaign which aimed to get him the most power in the country. He was elected Serbian president in 1990．In 1997, he became president of Yugoslavia. The rest of the story is well-known: his nationalist card caused Yugoslavia's other ethnic groups to fight for their own rights, power and lands. Yugoslavia broke up when four of the six republics declared independence in 1991．War started and lasted for years and millions died. Then Western countries intervened. NATO bombed Yugoslavia, and he eventually stepped down as state leader in 2000. Soon after this, Serbia's new government, led by Zoran Djindjic arrested him and sent him to face justice at the Yugoslav war crimes tribunal in the Hague.

单选题Medical Journals Medical journals are publications that report medical information to physicians and other health professionals. In the past, these journals were available only in print. With the development of electronic publishing, many medical journals now have Web sites on the Internet, and some journals publish only online. A few medical journals, like the Journal of the American Medical Association, are considered general medical journals because they cover many fields of medicine. Most medical journals are specialty journals that focus on a particular area of medicine. Medical journals publish many types of articles. Research articles report the results of research studies on a range of topics varying from the basic mechanisms of diseases to clinical trials that compare outcomes of different treatments. Review articles summarize and analyze the information available on a specific topic based on a careful search of the medical literature. Because the results of individual research studies can be affected by many factors, combining results from different studies on the same topic can be helpful in reaching conclusions about the scientific evidence for preventing, diagnosing or treating a particular disease. Case conferences and case reports may be published in medical journals to educate physicians about particular illnesses and how to treat at them. Editorials in medical journals are short essays that express the views of the authors, often regarding a research or review article published in the same issue. Editorials provide perspective on how the current article fits with other information on the same topic. Letters to the editor provide a way for readers of the medical journal to express comments, questions or criticisms about articles published in that journal.
