单选题{{B}}Text 4{{/B}} The telecity is a city whose life, direction, and functioning are largely shaped by telecommunications. In the twenty-first century; cities will be based more and more on an economy that is dependent on services and intellectual property. Telecommunications and information networks will define a city's architecture, shape, and character. Proximity in the telecity will be defined by the speed and bandwidth of networks as much as by geographical propinquity. In the, age of the telecity, New York and Singapore may be closer than, say, New York and Arkadelphia, Arkansas. Telecities will supersede megacities for several reasons, including the drive toward clean air, reducing pollution, energy conservation, more jobs based on services, and coping with the high cost of urban property. Now we must add the need to cope with terrorist threats in a high-technology world. Western mind-sets were clearly jolted in the wake of the terrorist attack on the World Trade Center in New York City and attacks in Indonesia, Saudi Arabia, and elsewhere. But the risks posed by twentieth-century patterns of urbanization and architecture have yet to register fully with political figures and leaders of industry. The Pentagon, for example, has been rebuilt in situation rather than distributed to multiple locations and connected by secure landlines and broadband wireless systems. Likewise, the reconstruction of the World Trade Center complex still represents a massive concentration of humanity and infrastructure. This is a remarkably shortsighted and dangerous vision of the future. The security risks, economic expenses, and environmental hazards of over centralization are everywhere, and they do not stop with skyscrapers and large governmental structures. There are risks also at seaports and airports, in food and water supplies, at nuclear power plants and hydroelectric turbines at major dams, in transportation systems, and in information and communications systems. This vulnerability applies not only to terrorist threats but also to human error, such as system-wide blackouts in North America in August 2003 and in Italy in September 2003, and natural disasters such as typhoons, hurricanes, floods, and earthquakes. Leaders and planners are only slowly becoming aware that over centralized facilities are the most vulnerable to attack or catastrophic destruction. There is also growing awareness that new broadband electronic systems now allow governments and corporations to safeguard their key assets and people in new and innovative ways. So far, corporations have been quickest to adjust to these new realities, and some governments have begun to adjust as well.

单选题 BRITISH universities can be depressing. The teachers moan about their pay and students worry they will end up frying burgers—or jobless. Perhaps they should try visiting McDonald's University in London's East Finchley. Students are often 'rough and ready', with poor qualifications and low self-esteem. But ambition-arousing pictures display the ladder of opportunity that leads from the grill (烤架) to the corner office (McDonald's chief executives have always started at the bottom). A map of the world shows the seven counterpart universities. Cabinets display trophies (奖杯) such as the Sunday Times award for being one of Britain's best 25 employers. McDonald's is one of Britain's biggest trainers. It gets about one million applicants a year, accepting only one in 15, and spends ￡40 million a year on training. The Finchley campus, opened by Margaret Thatcher in 1989, is one of the biggest training centers in Europe. It is part of a bigger system. An employees' web-portal, Our Lounge, provides training as well as details about that day's shifts, and allows employees to compete against each other in work-related video games. The focus is on practicalities. A retired policeman conducts a fast-paced class on conflict management. He shows a video of a woman driven angry by the fact that you cannot get chicken McNuggets at breakfast time. He asks the class if they have ever had a difficult customer, and every hand goes up. Students are then urged to share their advice. Self-esteem and self-management are included in the courses, too. A year-long apprenticeship program emphasizing English and maths leads to a nationally recognized qualification. McDonald's has paid for almost 100 people to get degrees from Manchester Metropolitan University. The company professes to be not confused by the fact that many graduates will end up working elsewhere. It needs to train people who might be managing a business with a ￡5m turnover (营业额) by their mid-20s. It also needs to satisfy the company's appetite for senior managers, one of whom will eventually control the entire global McDonald's empire.

单选题 A few years back, the decision to move the Barnes, a respected American art institution, from its current location in the suburban town of Merion, Pa., to a site in Philadelphia's museum district caused an argument—not only because it shamelessly went against the will of the founder, Albert C. Barnes, but also because it threatened to break a relationship among art, architecture and landscape critical to the Barnes's success as a museum. For any architect taking on the challenge of the new space, the confusion of moral and design questions might seem overwhelming (势不可挡的). What is an architect's responsibility to Barnes's vision of a marvelous but odd collection of early Modern artworks housed in a rambling (布局凌乱的) 1920s Beaux-Arts pile? Is it possible to reproduce its spirit in such a changed setting? Or does trying to copy the Barnes's unique atmosphere only doom (注定) you to failure? The answers of the New York architects taking the commission are not reassuring. The new Barnes will include many of the features that have become virtually mandatory (强制性的) in the museum world today—conservation and education departments, temporary exhibition space, bookstore, café— making it four times the size of the old Barnes. The architects have tried to compensate for this by laying out these spaces in an elaborate architectural procession that is clearly intended to copy the peacefulness, if not the fantastic charm, of the old museum. But the result is a complicated design. Almost every detail seems to ache from the strain of trying to preserve the spirit of the original building in a very different context. The failure to do so, despite such an earnest effort, is the strongest argument yet for why the Barnes should not be moved in the first place. The old Barnes is by no means an obvious model for a great museum. Inside the lighting is far from perfect, and the collection itself, mixing masterpieces by Cézanne, Picasso and Soutine with second-rate paintings by lesser-known artists, has a distinctly odd flavor. But these apparent flaws are also what have made the Barnes one of the country's most charming exhibition spaces. But today the new Barnes is after a different kind of audience. Although museum officials say the existing limits on crowd size will be kept, it is clearly meant to draw bigger numbers and more tourist dollars. For most visitors the relationship to the art will feel less immediate.
