87. For example, electronic communication filters out and alters much of the subtlety, warmth, contextuality, and so on that seem important to fully human, morally engaged interaction. That is one reason many Japanese and European executives persist in considering face-to-face encounter essential to their business dealings and why many engineers, too, prefer face-to-face encounter and find it essential to their creativity. 88. Even hypothetical new media (e. g. advanced "virtual realities"), conveying a dimensionally richer sensory display are unlikely to prove fully satisfactory, substitutes for face-to-face interaction. Electronic media decompose holistic experience into analytically distinct sensory dimensions and then transmit the latter. At the receiving end, people can resynthesize the resulting parts into a coherent experience, but the new whole is invariably different and, in some fundamental sense, less than the original. Second, there is evidence that screen-based technologies (such as TV and computer monitors) are prone to induce democratically unpromising psychopathologies, ranging from escapism to passivity, obsession, confusing watching with doing, withdrawal from other forms of social engagement, or distancing from moral consequences. Third, a strength--but also a drawback--to a virtual community is that any member can exit instantly. Indeed, an entire virtual community can decline or perish in the wink of an eye. 89. To the extent that membership in virtual communities proves less stable than that obtaining in other forms of democratic community, or that social relations prove less thick (i. e. less embedded in a context filled with shared meaning and history), there could be adverse consequences for individual psychological and moral development. 90. no matter with whom we communicate or how far our imaginations fly, our bodies--and hence many material interdependencies with other people--always remain locally situated. Thus it seems morally hazardous to commune with far-flung tele-mates, if that means growing indifferent to physical neighbors. It is not encouraging to observe just such indifference in California's Silicon Valley, one of the world's most "highly wired" regions. (66)

The motorcar will undoubtedly change significantly over the next 30 yearn. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types. Regardless of its power source, the auto in the future will still be the main problem in mi)an traffic congestion. One proposed solution to this problem is the automated highway system. When the auto enters the highway system, a retractable arm will drop from the auto and make contact with a mil, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements. The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best mute, and reserve space for the car an the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer that win warn him of his coming exit. It is estimated that au automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway. One significant improvement in the future car will probably be ______ A．its power source B．its driving system C．its monitoring system D．its seating capacity
