问题    The dream of personalised flight is still vivid in the minds of many inventors, some developing cycle-powered craft, others【C1】______money into jetpacks (喷气飞行背包). However, the flying car has always remained the【C2】______symbol of personal transport freedom.
   Several companies around the world have produced【C3】______that can drive on roads and fly. Airbus has a futuristic modular (组件式的) concept involving a passenger capsule that can be【C4】______from the road-going chassis (底盘) and picked up by a helicopter-type machine.
   But all these concepts are massively expensive, require safety certification standards for road and air, need【C5】______controls, involve complex folding wings and propellers, and have to be flown from air-strips. So they are likely to remain rich people’s playthings rather than practical transport solutions for the masses.
   "A car that takes off from some London street and lands in another【C6】______street is unlikely to happen," says Prof. Gray, a leading aeronautical engineer. "Sky taxis are much more likely. " But that won’t stop inventors from dreaming up new ways to fly and trying to persuade investors to back their sometimes【C7】______schemes.
   Civilian aviation is being disrupted, not by the age-old desires for speed, romanticism and【C8】______, but by the pressing need to respond to a changing climate. New electric engines coupled with artificial intelligence and【C9】______systems will contribute to a more efficient, integrated transport system that is less polluting and less noisy. That may sound simple, but as Prof. Gray says, "When I travel somewhere I like this notion that when I finish my journey I feel better than when I started it. That’s completely at【C10】______with how I feel today. " Now that would be progress.
   A) autonomous I) pouring
   B) detached J) prototypes
   C) dual K) random
   D) glamour L) repressing
   E) imminent M) segmented
   F) odds N) spectrum
   G) opposites O) ultimate
   H) outrageous
【C7】
选项
答案H
解析 形容词辨析题。空格位于名词前，应填入形容词作定语。空格上文已经提到，发明家的很多想法，如空中飞车，是不大可能实现的。空格所在句提到，这并不能阻止他们继续构思各种新鲜的飞行方式。由此可知，他们的计划有时是不切实际的，符合本意的只有H)outrageous“极不寻常的，骇人的”。
