单选题The Warranty Holdings Group, a European leader in mechanical breakdown insurance and a researcher and commentator on trends in motoring, says that the motorists' world 20 years from now will be marked by more cars, more choice and more technology. Built-in safety features will increase and will include night-vision and collision-avoidance system, and monitoring devices to stop drivers falling asleep at the wheel. A growth in tele-working and home shopping should cut the numbers of trips in a car made by most motorists and "fun" sports cars will become popular as private motoring becomes more recreational in nature. The survey results show that despite years of research into alternative fuel sources for vehicles, no clear winner has emerged for a replacement for the conventional petrol-engined car. Gas and electricity are the best possibilities, with Toyota's design division in Japan claiming it already has an electric car that will drive up to 250km on a single charge. However, while electric and "hybrid" powered vehicles will be far more in evidence in the future, it will take a major technological breakthrough to steer the car industry away from its current path of gradual improvements to the petrol-driven internal combustion engine. Professor Garel Rhys, of the Cardiff Business School in Wales, says engine fuel injection systems of the future will be far more frugal than anything that exists at the moment. "It will be like putting a pipette of petrol into the cylinders, rather than just throwing it in by the bucket load, which is almost what we do at the moment when you compare it with what could be possible. " Some environmentalists point to the Twingo, the small car developed by France's Renault company, to show that what could be achieved by the world's car industry if it moved away from a trend towards bigger and more powerful cars and radically cut the fuel consumption of its products. Public opinion polls in many countries show motorists wanting access to this kind of environmentally-aware car. A prototype environmental car, the SmILE (smaller, intelligent, lighten. efficient) has been put together by the environmental group Greenpeace. The group hopes the concept will catch on. It depends heavily on supercharging or forcing fuel mixture into the cylinders at higher than normal pressure. Some experts say this is a good way to extract high performance and high fuel efficiency from small engines. Cutting the fuel consumption has had no negative effect on the handling or performance of the car, according to the designers. Top speed, flexibility and acceleration from the engine is as good or better than the original Twingo. They say the technology used to create the Twingo SmILE could just as easily be used on other brands of car. What remains to be seen is whether the enthusiasm of environmental designers catches on with the dollar-driven international car industry, and whether motorists back up with their chequebooks their desire for "greener" cars.

单选题Forget Harry Potter. No matter that the film about this schoolboy with magic powers broke all box-office records on its opening weekend, taking $94 m in the United States and $23 m in Britain, the truly momentous phenomenon in the film industry is not a pre-pubescent wizard but a humble circular piece of plastic: the digital versatile disc (DVD). Next year, for the first time, sales of movies in DVD format are forecast to outsell those on video cassette in America, reaching a total of $9.5 billion, according to Morgan Stanley, an investment bank. Already, 80% of American households have DVD players. With a DVD recorder now in the shops as well, something that can record from the TV as well as play the discs, Christmas sales are expected to be strong. A technology considered a flop when it was launched in 1997 is now the basis for the fastest-growing consumer appliance ever. Some in the film business complain that people are simply buying DVDs instead of video cassettes: there is no net gain. Yet DVDs can do things that the cassette cannot. such as offer a choice of language in which to watch a movie, not to mention a clearer picture. And the studios have cleverly stuffed DVDs full of lively extra features, such as new clips or interviews with the director. Moreover, people appear to want to build up collections of DVDs, rather as they do of recorded music. The DVD is steadily gaining shelf space, even in the movie-rental store, and it should overtake (赶上，追上) the cassette even there within three years. And shops like DVDs, not least because they take up less space. The DVD could well boost the size of the overall home-video market. Already, recent releases on DVD, such as Snow White and the Seven Dwarfs and Star Wars Episode One, have sold millions of copies each. At a time when any revenue growth in the media industry is startling, DVD sales at AOL Time Warner jumped by 44% in the third quarter this year, compared with the same period of 2000, to $279 m. But how lasting will the DVD effect be? Some 80% of a film's revenue comes from its distribution after the cinema release: to home video, pay-TV and the like. "The largest single portion of that revenue will be the DVD business, " says Christopher Dixon of UBS Warburg, an investment bank, which in turn will help to reduce the risk involved in making movies. "The DVD if the most exciting development in the film industry, " he adds, "but every eight years there has been a new distribution platform in the entertainment business. None of them lasts forever. /

单选题Despite a cooling of the economy, high technology companies are still crying out for skilled workers. The Information Technology Association of America projects that more than 800000 technology jobs will go unfilled next year. The lack of qualified workers poses a huge threat to the U. S. economy. The most commonly cited reason for this state of affairs is that the country's agrarian-age education system, separated from the needs of the business world, fails to prepare students in the primary and secondary grades for twenty-first-century work. Yet an inadequate and outmoded education system is only part of the problem. A less tangible but equally powerful cause is an antique classification system that divides the workforce into two camps: white-collar knowledge workers and blue-collar manual laborers. Blue-collar workers emerged in the United States during the Industrial Age as work migrated from farms to factories. White-collar office workers became a significant class in the twentieth century, outnumbering their blue-collar brethren by mid-century. But the white or blue paradigm has clearly outlived its utility. Corporations increasingly require a new layer of knowledge worker: a highly skilled multi-disciplinarian who combines the mind of the white-collar worker with the hands of the blue-collar employee. Armed with a solid grounding in mathematics and science (physics, chemistry and biology), these "gold-collar" workers—so named for their contributions to their companies and to the economy, as well as for their personal earning ability—apply that knowledge to technology. Of course, the gold-collar worker already exists in a wide range of jobs across a wide range of businesses: think of the maintenance technician who tests and repairs aircraft systems at American Airlines; the network administrator who manages systems and network operations at P＆G; the advanced-manufacturing technician at Intel. But until American business recognizes these people as a new class of worker, one whose collar is neither blue nor white, demands that schools do a better job of preparing employees for the twenty-first-century workforce will be futile. Certainly, polytechnic high schools, colleges, and universities have made heroic efforts to teach workers new skills. But because many people see these initiatives as primarily training blue-collar workers, adequate funds are not invested in such programs, leaving them short of state-of-the-art tools and experienced teachers. And because gold-collar workers need to constantly update their skills to stay current with emerging technology, learning must be a continuous process, one that is funded by companies as well as by taxpayers.

单选题What began with the invention of the telephone in 1876 has today become a global net of cables, satellites, transmitters, and receivers that enables half the population of the planet to exchange works, data, and images in seconds. It could take less than 25 years more to give the other half of the world's people this same power. The unified global telecommunications system, which is called "the Meganet", represents the greatest construction project ever undertaken. If present trends continue, by early in the 21st century the Meganet will link every computer terminal, fax machine, databank, and telephone instrument on earth. Unlike its anarchic (无政府主义的) cousin the Internet, which evolved from free interaction among interest groups of computer users. the Meganet of local telephone service, long-distance lines, communications satellites, and mobile relays has been planned, constructed, regulated and largely sponsored by governments and for-profit business interests. As new materials and technologies bring reliable voice and data links to formerly isolated or closed communities, political and economic power struggles grow. The Meganet breaks long-established patterns of social identity and responsibility. Where private individuals have uncensored access to global information sources, local standards of legality or decency become difficult even to set, let alone to enforce. Economic values may shift, too. Public utility companies have long supplied electric power over miles of high-tension lines, or pumped water through underground pipelines into thousands of homes. Now they are finding that their power-line rights-of-way and physical into-home connections let them compete with cable TV and phone companies to supply information services as well. Meganet impacts are often double-edged for finance and business, too. New York's Wall Street district lost 20% of its work force—some 100000 jobs—in less than a decade, as computers took over tasks once performed by clerks and banks did more of their business by phone transfers and automated teller machines.
