单选题Historically, TV's interest in "green" issues has been limited to the green that spends and makes the world go round. (That, and Martians. ) As for environmentalism, TV is where people watch SUV ads on energy-sucking giant screens that are as thirsty as a Bavarian at Oktoberfest. But with the greening of politics and pop culture from A1 Gore to Leo DiCaprio to Homer and Marge in The Simpsons Movie—TV is jumping on the biodiesel-fueled bandwagon. In November, NBC (plus Bravo, Sci Fi and other sister channels) will run a week of green-themed episodes, from news to sitcoms. CBS has added a "Going Green" segment to The Early Show. And Fox says it will work climate change into the next season of 24. ("Dammit, Chloe, there's no time! The polar ice cap's going to melt in 15 minutes!") On HGTV's Living with Ed, actor Ed Begley Jr. offers tips for eco-living from his solar-powered house in Studio City, Calif.-see him energy-audit Cheryl Tiegs! —while Sundance airs its documentary block "The Green. " MTV will set The Real World: Hollywood in a "green" house. Next year Discovery launches 24-hour eco-lifestyle channel Planet Green, a plan validated this spring when the eco-minded documentary Planet Earth became a huge hit for Discovery. "Green is part of [Discovery' s] heritage," says Planet Green president Eileen O'Neill. "But as pop culture was starting to recognize it, we realized we could do a better job positioning ourselves." Clearly this is not all pure altruism. Those popular, energy-stingy compact fluorescent bulbs? NBC's owner, General Electric, has managed to sell one or two. "When you have them being a market leader and saying this makes good business sense, people listen to that on (the TV) side," says Lauren Zalaznick, Bravo Media president, who is heading NBC's effort. And green pitches resonate with young and well-heeled viewers (the type who buy Priuses and $2-a-lb. organic apples), two groups the networks are fond of. NBC is confident enough in its green week's appeal to schedule it in sweeps. It's an unlikely marriage of motives. Ad-supported TV is a consumption medium: it persuades you to want and buy stuff. Traditional home shows about renovating and decorating are catnip for retailers like Lowe's and Home Depot. Of course, there are green alternatives to common purchases: renewable wood, Energy Star appliances, hybrid ears. But sometimes the greener choice is simply not to buy so much junk-not the friendliest sell to advertisers. The bigger hurdle, though, may be creative. How the NBC shows will work in the messages is still up in the air. (Will the Deal or No Deal babes wear hemp miniskirts? Will the Bionic Woman get wired for solar?) Interviewed after the 24 announcement, executive producer Howard Gordon hedged a bit on Fox's green promises. "It'll probably be more in the props. We might see somebody drive a hybrid." Will it work? Green is a natural fit on cable lifestyle shows or news programs—though enlisting a news division to do advocacy has its own issues. But commanding a sitcom like The Office to work in an earnest environmental theme sounds like the kind of high-handed p. r. directive that might be satirized on, well, The Office. Even Begley—formerly of St. Elsewhere—notes that the movie Chinatown worked because it kept the subplot about the water supply in Los Angeles well in the background. "It's a story about getting away with murder, and the water story is woven in." Of course, in an era of rampant product placement, there are worse things than persuading viewers to buy a less wasteful light bulb by hanging one over Jack Bauer as he tortures a terrorist. The greatest challenge—for viewers as well as programmers—is not letting entertainment become a substitute for action; making and watching right-minded shows isn't enough in itself. The 2007 Emmy Awards, for a start, aims to be carbon neutral, solar power, biodiesel generators, hybrids for the stars, bikes for production assistants—though the Academy cancelled Fox's idea to change the red carpet, no kidding, to green. The most potent message may be seeing Hollywood walk the walk, in a town in which people prefer to drive.

单选题 Large parts of the world have not enjoyed the remarkable global progress in health conditions that have taken place over the past century. Indeed, millions of deaths in impoverished nations are avoidable with prevention and treatment options that the rich world already uses. This year, 10 million children will die in low and middle income countries. If child death rates were the same as those in developed countries this figure would be lower than 1 million. Conversely, if child death rates were those of rich countries just 100 years ago, the figure would be 30 million. Today's tools for improving health are so powerful and inexpensive that health conditions could be reasonably good even in poor countries if policy makers spent even relatively little in the right places. Recent research for the Copenhagen Consensus identifies several highly cost-effective options that would tackle some of the planet's most urgent health problems. The most promising investment is in tuberculosis treatment. Some 90 percent of the 1.6 million tuberculosis deaths in 2003 occurred in low-and middle-income countries. Because tuberculosis affects working-age people, it can be a trigger of household poverty. The cornerstone of control is prompt treatment using first-line drugs, which doesn't require a sophisticated health system. Spending $1 billion on tuberculosis treatment in a year would save 1 million lives. Because good health accompanies higher levels of national economic welfare in the long run, the economic benefits are worth $ 30 billion. The second most cost-effective investment is tackling heart disease. Heart disease might not seem like a pressing issue for poor nations, but it represents more than a quarter of their death toll. Measures to reduce risk factors other than smoking — high intake or saturated animal fat, obesity, binge drinking of. alcohol, physical inactivity, and low fruit and vegetable consumption — have had little success. Treating acute heart attacks with inexpensive drugs is, however, cost-effective. Spending $ 200 million could avert several hundred thousand deaths, yielding benefits that are 25 times higher than costs. The third option is prevention and treatment of malaria. A billion dollars would expand the provision of insecticide-treated bed-nets and facilitate provision of highly effective treatment. This would save more than a million child deaths and produce economic benefits worth $ 20 billion. The fourth alternative for policymakers is to focus on child health initiatives. The best measures are familiar ones expanding immunization coverage, promoting breastfeeding, increasing the use of simple and cheap treatments for diarrhea and childhood pneumonia, and so on. Even if the costs of all these initiatives were two or three times higher than we estimate, these efforts would still provide amazing opportunities to reduce health inequality and do good in the world.

单选题When prehistoric man arrived in new parts of the world, something strange happened to the large animals: they suddenly became extinct. Smaller species survived. The large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans. That the seas are being overfished has been known for years. What researchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then. Dr. Worm acknowledges that these figures are conservative. One mason for this is that fishing technology has improved. Today"s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since no baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now. Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the "shifting baseline". The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.

单选题A meager diet may give you health and long life, but it's not much fun—and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don't start to diet until old age. Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins. Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes. "This is the first indication that these effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C.. No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says. If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective. But Spindler isn't sure the trade-off is worth it. "The mice get less disease, they live longer, but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'." Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction.

单选题Questions 11 to 15 are based on the following talk.

单选题 The early retirement of experienced workers is seriously harming the U.S. economy, according to a new report from the Hudson Institute, a public policy research organization. Currently, many older experienced workers retire at an early age. According to the recently issued statistics, 79 percent of qualified workers begin collecting retirement benefits at age 62; if that trend continues, there will be a labor shortage that will hinder the economic growth in the twenty-first century. Older Americans constitute an increasing proportion of the population, according to the US. Census Bureau, and the population of those over age 65 will grow by 60% between 2001 and 2020. During the same period, the group aged 18 to 44 will increase by only 4%. Keeping older skilled workers employed, even part time, would increase U.S. economic output and strengthen the tax base; but without significant policy reforms, massive early retirement among baby boomers seems more likely. Retirement at age 62 is an economically rational decision today. Social Security and Medicaid earnings limits and tax penalties subject our most experienced workers to marginal tax rates as high as 67%. Social Security formulas encourage early retirement. Although incomes usually rise with additional years of work, any pay increases after the 35-year mark result in higher Social Security taxes but only small increases in benefits. Hudson Institute researchers believe that federal tax and benefit policies are at fault and reforms are urgently needed, but they disagree with the popular proposal that much older Americans will have to work because Social Security will not support them and that baby boomers are not saving enough for retirement. According to the increase in 401 (k) and Keogh retirement plans, the ongoing stock market on Wall Street, and the likelihood of large inheritances, them is evidence that baby boomers will reach age 65 with greater financial assets than previous generations. The Hudson institute advocates reforming government policies that now discourage work and savings, especially for older worker. Among the report's recommendations: tax half of all Social Security benefits, regardless of other income; provide 8% larger benefits for each year beyond 65; and permit workers nearing retirement to negotiate compensation packages that may include a lower salary but with greater healthcare benefits. However, it may take real and fruitful planning to find the right solution to the early retirement of older experienced workers; any measures taken must be allowed to prolong the service ability of older experienced workers.

单选题Questions 1～5 Why the inductive and mathematical sciences, after their first rapid development at the culmination of Greek civilization, advanced so slowly for two thousand years—and why in the following two hundred years a knowledge of natural and mathematical science has accumulated, which so vastly exceeds all that was previously known that these sciences may be justly regarded as the products of our own times—are questions which have interested the modern philosopher not less than the objects with which these sciences are more immediately conversant. Was it the employment of a new method of research, or in the exercise of greater virtue in the use of the old methods, that this singular modern phenomenon had its origin? Was the long period one of arrested development, and is the modern era one of normal growth? Or should we ascribe the characteristics of both periods to so-called historical accidents—to the influence of conjunctions in circumstances of which no explanation is possible, save in the omnipotence and wisdom of a guiding Providence? The explanation which has become commonplace, that the ancients employed deduction chiefly in their scientific inquiries, while the moderns employ induction, proves to be too narrow, and fails upon close examination to point with sufficient distinctness the contrast that is evident between ancient and modern scientific doctrines and inquiries. For all knowledge is founded on observation, and proceeds from this by analysis, by synthesis and analysis, by induction and deduction, and if possible by verification, or by new appeals to observation under the guidance of deduction—by steps which are indeed correlative parts of one method; and the ancient sciences afford examples of every one of these methods, or parts of one method, which have been generalized from the examples of science. A failure to employ or to employ adequately any one of these partial methods, an imperfection in the arts and resources of observation and experiment, carelessness in observation, neglect of relevant facts, by appeal to experiment and observation—these are the faults which cause all failures to ascertain truth, whether among the ancients or the moderns; but this statement does not explain why the modern is possessed of a greater virtue, and by what means he attained his superiority. Much less does it explain the sudden growth of science in recent times. The attempt to discover the explanation of this phenomenon in the antithesis of "facts" and "theories" or "facts" and "ideas"—in the neglect among the ancients of the former, and their too exclusive attention to the latter—proves also to be too narrow, as well as open to the charge of vagueness. For in the first place, the antithesis is not complete. Facts and theories are not coordinate species. Theories, if true, are facts—a particular class of facts indeed, generally complex, and if a logical connection subsists between their constituents, have all the positive attributes of theories. Nevertheless, this distinction, however inadequate it may be to explain the source of true method in science, is well founded, and connotes an important character in true method. A fact is a proposition of simple. A theory, on the other hand, if true has all the characteristics of a fact, except that its verification is possible only by indirect, remote, and difficult means. To convert theories into facts is to add simple verification, and the theory thus acquires the full characteristics of a fact.

单选题 Doctors alone must make the final decision whether to withdraw treatment, including artificial feeding, and allow a terminally ill patient to die, according to British Medical Association guidelines published yesterday. They must consult the family, take into account views of the patient and get a second medical opinion. But ultimately the responsibility rests with the doctor, and if the family disagrees it can only challenge his or her decision in the courts. Members of the BMA’s ethics committee, which produced the guidelines, said they were not a charter for euthanasia. "This is not about intending to kill people. It is about intending to withdraw what people believe to be useless or non-beneficial interventions," said Raanan Gillon, a GP and professor of medical ethics at Imperial College, London. "It is the difference between foreseeing death as the outcome and intending it." Opponents of euthanasia rejected this distinction. "I am deeply concerned that some doctors might interpret the guidelines to increase the number of unnatural deaths," said Dr Andrew Fergusson, chairman of the pressure group Healthcare Opposed to Euthanasia. "I recognize these are very difficult matters, but I am anxious about even more power being given to doctors in the apparent absence of adequate safeguards. This guidance will be bad for some patients." The BMA has produced the guidelines because of confusion and uncertainly among doctors over how to proceed when treatment is doing more harm than good—perhaps in the case of unsuccessful chemotherapy for cancer—or when a patient is incapacitated after a severe stroke or advanced dementia. The House of Lords judgment in the 1993 Bland case has muddied the waters. Tony Bland was in a persistent vegetative state (PVS) after the Hillsborough disaster. The courts backed the BMA view that the artificial feeding and hydration through a tube that were keeping him alive were medical treatments. His father won permission to have all treatments stopped and his son was allowed to die. But the Lords stated that their ruling applied only to patients in PVS and suggested each case should be referred in turn to the courts. The BMA guidelines make clear that they feel there is no such need in cases other than PVS. These are hard decisions, but doctors are well qualified to make them. If the decision involves stopping artificial nutrition and hydration, which the document accepts is an emotive issue, then a second opinion from a specialist unconnected with the case must be sought. The doctor must try to ascertain the patient's own wishes. The views of children under 16 who are capable of understanding must be respected and their parents' views sought. Living wills requesting no further treatment must be complied with. With patients who cannot communicate, doctors must consider among other things whether the invasiveness and pain of treatment are justifiable, how likely is any improvement and how aware patients are of the world around them. The document accuses society of "unrealistic expectations.., about the extent to which it is possible to postpone death." But SOS-NHS Patients in Danger, a pressure group formed by relatives of patients who have died in hospital, rejected the guidelines outright. It said: "A terminally iii patient, with weeks, months and (who knows) even years to live would not benefit from having their death hastened for the convenience of medical staff and managers when they and their family might have other plans for how they wish to spend their precious remaining time together."

单选题Questions 23-26

单选题In general, our society is becoming one of giant enterprises directed by a bureaucratic management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, well-ventilated factories and piped music, and by psychologists and "human-relations" experts; yet all this oiling does not alter the fact that man has become powerless, that he does not wholeheartedly participate in his work and that he is bored with it. In fact, the blue-and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management. The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction or interest in life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings. Those higher up on the social ladder axe no less anxious. Their lives axe no less empty than those of their subordinates. They axe even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the right mixture of submissiveness and independence. From that moment on they axe tested again and again--by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one"s fellow-competitor creates constant anxiety and stress, the very causes of unhappiness and illness. Am I suggesting that we should return to the preindustrial mode of production or to nineteenth-century "free enterprise" capitalism? Certainly not. Problems axe never solved by returning to a stage which one has already outgrown. I suggest transforming our social system from a bureaucratically managed industrialism in which maximal production and consumption axe ends in themselves into a humanist industrialism in which man and full development of his potentialities—those of love and of reason--are the aims of all social arrangements. Production and consumption should serve only as means to this end, and should be prevented from ruling man.

单选题 Parenting was never a piece of cake in any age, but probably the greatest source of headache for parents today in Japan is the ubiquitous cellphone. Today, 96 percent of senior high school students and 58 percent of junior high school students have cellphones. Even among primary school children, 31 percent have them. By enabling youngsters to stay connected with their parents at all times, these gadgets help to keep children safe. For the kids, they are fun toys, too, that let them text to or chat with their pals whenever they want, play Internet games, and enjoy blogging for their own profile and diary purposes. But terrible dangers lurk beneath all that fun and convenience. Every year about h 000 children become involved in rape and other crimes through dating service sites. Violent and obscene images are only a couple of clicks away. On gakkoura saito, or so-called unofficial school websites where kids can post whatever they want, anyone can fall victim to brutal "verbal mob lynching" by their peers. Amid today's urgent need to address these problems, the government's Meeting on Education Rebuilding has issued a report. In response to the Prime Minister's recent comments — "I cannot think of one good reason for (letting youngsters) have a cellphone" and "I would like everyone to discuss whether cellphones are really necessary" — the report recommended that "parents, guardians, schools and all parties concerned should cooperate among themselves, so that elementary school pupils and junior high school students do not have a cellphone unless there is a compelling reason for them to do so." But since many parents believe in the necessity of cellphones as a safety tool, it is unrealistic to expect everyone to do away with them. Rather, it would make more sense for guardians, schools and cellphone companies to consider, from their respective standpoints, how cellphones should be used by children. We suggest that parents sit down with their offsprings and talk about their "house rules" for cellphone use. For instance, set the hours allowed, so the kids won't be texting to their friends late into the night, remind them never to give away personal information online, and so on, But there are limits to what individual families can do, and this is where we also suggest that schools should educate their pupils on the dangers of cellphone use. One way to go about this, for instance, may be for each class to set its own rules on sending e-mail messages.
