单选题In the 1997 general-election campaign, "Education, Education" was Tony Blair"s pet phrase. Times change quickly. Education is going rapidly out of fashion. "Learning" (to be exact, "lifelong learning") is New Labour"s new buzzword (时髦语). The shift from "education" to "learning" reflects more than a change of language. It stems from both educational research and left-wing ideas. During the 1980s, British educationalists got some new American ideas. One was the notion that traditional examinations do not test the full range of people"s abilities. Another was the belief that skills are not necessarily learned from teachers in a conventional classroom. People can pick them up in all sorts of ways. All this echoed left-wing ideas that traditional teaching methods were not sufficiently adaptable to the needs of individual learners. Advocates of lifelong learning argue that it merely describes what has changed in education in the past decade. And there are now hundreds of schemes in which pupils learn outside the classroom. Until now, education has been changing from below. In the next few weeks, the government will help from above. One of its main projects for lifelong learning is about to begin its first pilot programs. With funding of $44 million in its first year, it will coordinate a new network of "learning centers" throughout the country. Traditional institutions, such as schools and colleges, will provide training at some nontraditional places of learning, such as supermarkets, pubs, and churches. The theory is that in such places students will feel more at ease, and therefore will be better motivated, than in a classroom. The new schemes allow consumers of education to exercise complete choice over where, what and when they learn. In the rest of the state-run education sectors (部门), the government still seems to be committed to restricting choices as much as possible. If these programs succeed, they could improve the skills of Britain"s workforce.

单选题The examples placed before a nation are vital. What we constantly observe, we tend to copy. What we reward, we perpetuate. This is why John Glenn himself is almost as important as his flight into outer space, for he dramatized before the eyes of the whole nation the noblest qualities of the human spirit. Outside of the morality-play of our cowboy movies, where the hero always gets the girl and the villain always gets slugged behind the saloons, courage, modesty, quiet patriotism, love of family and religious faith are not exactly the predominant themes of our novels, plays, TV shows, movies or newspapers these days. Yet Glenn dramatized them all coast to coast and around the world. This was no insensitive robot who landed here from the heavens yesterday morning, but a warm and thoughtful human being: natural, orderly, considerate and, at times, quietly amusing and even eloquent. His departure from Cape Canaveral was a technical triumph, but his return was a human triumph. This memorable performance, of course, may not stamp out juvenile delinquency overnight, but the models of the nation--not the uncovered cover girls of today but the larger models of human character--are probably more important than this age believes. When Walter Bagehot, the English editor and scientist, made his famous study 100 years ago of why some nations progressed, he concluded that what a nation admired and despised was almost as important as its military power. "Slighter causes than is commonly thought," he said, "may change a nation from the stationary to the progressive state of civilization, and from the stationary to the degrading." It all depended, he insisted, on the model of character emulated or eliminated. If this was true in the middle of the nineteenth century it has even more validity in this age of instantaneous communication. Only a few hundred people heard Lincoln's Gettysburg Address. New models and styles are now set by television every day, but most of them are models of cars and styles of dresses and hairdos. What transcontinental television did for the nation on the Glenn story illustrates the wider application of the idea. It almost made up for what it does to us the rest of the time, but not quite. Meanwhile, the question remains: how many more John Clenns and A1 Shepards are hiding in this country? Outer space is a long way to go to discover a new generation of leaders of men, but if we have to recruit them there, why not? Human weightlessness is almost our major problem in Washington and, since these astronauts know more about it than anybody else, maybe a couple of them should be transferred to the thin hot air of the capital. After all, Glenn is 40 and even if he looks like the freshman football coach at Muskingum College he can't go off spinning around the earth without his Annie forever. Once Christopher Columbus had discovered America, Ferdinand and Isabella didn't insist that he go back every Tuesday. Besides, is the moon worth John Glenn when we need him so badly on earth?

单选题Interest is steadily spreading from a minority of enthusiasts in developing renewable sources of energy—wind, wave and solar power, tidal and geothermal energy. Additional support for them has come with a proposal to explore the untapped sources of hydro-electric power in Scotland. The details are presented by Mr. William Manser in a study called "The Case for an Inquiry into Hydro-Electric Generation in the North of Scotland" He calls for an expert committee to look at the developments possible for hydro-electric sites and, more important, for means of financing them. There is a clear industrial connection in Mr. Manser's study because it was done for the Federation of Civil Engineering Contractors; hydro-electric schemes, by definition, have a large civil engineering component in them. Mr. Manser estimates that wind power could theoretically provide more than 7 per cent of electricity supply in the United Kingdom, provided suitable sites for generators could be found. However, the practical viability of wind power generation is not likely to be understood until 1990. Other developments using renewable energy sources are also at an early stage as far as their commercial possibilities are concerned, he believes. The best developed and most suitable form of renewable energy is, in his view, hydro-power. The technology has been developed over centuries and is still progressing. At present it is the cheapest form of electricity generation. Mr. Manser examined past surveys of the north of Scotland and identified several as suitable for hydro-electric generation. Those are in the remote areas, usually of great natural beauty. But Mr. Manser says a well-designed dam can be impressive in itself. It is also possible to make installations as unobtrusive as possible, to the point of burying parts of them. Hydro-generation involves no water pollution, smoke creation or unsightly stocking-out yards. The main trouble, appearing from his report, is financing an undertaking which has a heavy initial capital cost, and very low running costs. However, Mr. Manser does not see that as an unfamiliar position for the electricity industry. He cites the proposed construction of the new nuclear power station at Sizewell in Suffolk, which will have a high initial capital cost. The argument as Sizewell that the reason for the expenditure is that the capital will provide a benefit in lower costs and higher returns in the long-term, applies equally to hydro-electric generation.

单选题Can the Internet help patients jump the line at the doctor"s office? The Silicon Valley Employers Forum, a sophisticated group of technology companies, is launching a pilot program to test online "virtual visits" between doctors at three big local medical groups and about 8,000 employees and their families. The six employers taking part in the Silicon Valley initiative, including heavy hitters such as Oracle and Cisco Systems, hope that online visits will mean employees won"t have to skip work to tend to minor ailment or to follow up on chronic conditions. "With our long commutes and traffic, driving 40 miles to your doctor in your hometown can be a big chunk of time," says Cindy Conway, benefits director at Cadence Design Systems, one of the participating companies. Doctors aren"t clamoring to chat with patients online for free; they spend enough unpaid time on the phone. Only 1 in 5 has ever E-mailed a patient, and just 9 percent are interested in doing so, according to the research firm Cyber Dialogue. "We are not stupid," says Stirling Somers, executive director of the Silicon Valley Employers group. "Doctors getting paid is a critical piece in getting this to work." In the pilot program, physicians will get $ 20 per online consultation, about what they get for a simple office visit. Doctors also fear they"ll be swamped by rambling E-mails that tell everything but what"s needed to make a diagnosis. So the new program will use technology supplied by Healinx, an Alameda, Calif.-based start-up. Healinx"s "Smart Symptom Wizard" questions patients and turns answers into a succinct message. The company has online dialogues for 60 common conditions. The doctor can then diagnose the problem and outline a treatment plan, which could include E-mailing a prescription or a face to face visit. Can E-mail replace the doctor"s office? Many conditions, such as persistent cough, require a stethoscope to discover what"s wrong—and to avoid a malpractice suit. Even Larry Bonham, head of one of the doctor"s groups in the pilot, believes the virtual doctor"s visits offer a "very narrow" sliver of service between phone calls to an advice nurse and a visit to the clinic. The pilot program, set to end in nine months, also hopes to determine whether online visits will boost worker productivity enough to offset the cost of the service. So far, the Internet"s record in the health field has been underwhelming. The experiment is "a huge roll of the dice for Healinx," notes Michael Barrett, and analyst at Internet consulting from Forester Research. If the "Web visits" succeed, expect some HMOs (Health Maintenance Organizations) to pay for online visits. If doctors, employers, and patients aren"t satisfied, figure on one more E-health start-up to stand down.

单选题In contrast, when the general population of a society is going through the early stages of social mobilization, language group conflicts seem particularly likely to occur. They may develop animosities which take on a life of their own and persist beyond the situation which gives rise to them.
