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 [br] 【C5】
选项
答案
C
解析
形容词辨析题。空格位于动词和名词之间,应填入形容词作定语。本句中,are、require、need、involve和have to为并列动词作谓语。空格前一句提到,“这些概念需要陆空两栖的安全认证标准”,空格后面又出现了“折叠翼和推进器”,都是在强调空中飞车涉及陆空两方面的难度,故空格处填入C)dual“双重的,两部分的”,意为“需要陆空两套操控装置”。
