单选题The economic costs of noise are several. Airports are currently operating at less than 27 because of noise regulations which restrict their hours of operation. For instance, at Washington's National Airport no jet traffic is allowed from 11 p.m. to 7 a.m. Other airports restrict the use ofcertain runway. One estimate is that noise 28 reduce possible airport use by 20 percent. The 29 cargo trade is especially affected by night restrictions. In the case of airports, jet engines may be 30 to reduce their noise level, or insulation from air traffic noise may be provided by the purchase of land around airports or the insulation of buildings. One estimate is that $5.7 billion would be required to 31 all existing jet engines with noise control devices. However, 32 the current state of the art, even taking this step will not reduce noise levels at all points to 33 values. Some combination of methods is probably necessary. If all aircraft were made quieter by existing methods, there would be a number of economic benefits. An increase in airport capacity would 34 . Property values near airports might rise. Transportation costs to and from airports could be reduced since the airports now could be located closer to population center. Much research still needs to be done on the economic 35 of noise reduction and noise effects. Although some of the effects of noise pollution are known, more must be discovered about its effects on health, productivity, property values and the quality of life. 36 , the cost of noise pollution control to the economy as a whole needs to be investigated.

单选题Likenesses of Buddha are these days SO commonplace—the casual adornment of fashionable spas, fusion restaurants and Parisian nightclubs—that it is strange to think that artists once hesitated, out of reverence, to portray the Buddha in corporeal form. In 2nd century India, judging by a 2nd century sandstone carving excavated from Mathura, it was sufficient to simply depict an empty throne—the implication that the Buddha was a spiritual king being very clearly understood by anyone who saw it. But as the stunning new gallery of Buddhist sculpture at London"s Victoria and Albert Museum makes Plain, somewhere along the line the reticence (沉默) about rendering the Buddha"s likeness gave way, and the world embarked on two millenniums of rich iconography and statuary. The gallery"s 47 masterworks, chosen from the museum"s renowned Asian collections, trace the Buddha"s portrayal from the 2nd to the 19th centuries, in places as diverse as India, Java and Japan. Inspiration came from unexpected sources. Some sculptors in Sri Lanka and China simply shaped the Buddha in their own likenesses. A 4th century stucco bust unearthed in Afghanistan features the full lips associated with Indian Gupta art, but also fulsome curls that reflect the Greco-Roman artists brought to the region by Alexander the Great. Other enlightened souls are shown beside the Buddha. Among the gallery"s most glorious artifacts are depictions of bodhisattvas—those who deliberately postpone their passage to nirvana (涅槃), Buddhists believe, in order to help others along the eightfold path. In the 14th century, metalworkers from Nepal"s Kathmandu Valley crafted the Bodhisattva Avalokiteshvara, a manifestation of the Buddhist lord of compassion, in gilded copper and precious-stone inlay. An androgYnous-looking deity with wide hips and sensuous form (in Chinese tradition, Avalokiteshvara or Guan Yin is female, in others male), Avalokiteshvara"s serene face projects the harmony to which all Buddhists aspire. John Clarke, the gallery"s principal curator, says that Avalokiteshvara is sometimes depicted holding a blooming lotus—a symbol of spiritual purity. "It comes up from the mud, flowers, and remains untouched by the dirt that surrounded it," he says. You could say the same thing for the wonderful richness of Buddhist art.

单选题At the first sight the planet Mars does not appear very welcome to any kind of life. It has very little oxygen and water, the temperature at night is below -50~Cand winds of 100 miles per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it some time in the past, and it is believed that there is enough ice at the poles to cover the planet with water if it melts. Although there is no life on the Mars now, some scientists think that there may have been some form of life long time ago. At that time, the planet had active volcanoes; the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists. Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere. With warmth, water and carbon dioxide (二氧化碳), simple plants could begin to grow. These plants could slowly make the Mars more suitable for living. It is estimated that the whole process might take between 100,000 and 200,000 years. In the meantime, people could begin to live on the planet in special closed environments. They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.
