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     F) odds            K) random
    B)  detached       G) opposites       L) repressing
    C)  dual           H) outrageous      M) segmented
    D)  glamour        I)  pouring        N) spectrum
    E)   imminent      J) prototypes      O) ultimate
【C6】
选项
答案K
解析 形容词辨析题。空格位于名词前，应填入形容词作定语。本句中的takes off“起飞”和lands in“降落”是对应的，空格前一句提到了some London street“伦敦的某条街道”，具有泛指性，由此推测后面的another street也应是泛指的，故填入K)random“随机的，随意的”。本句意为：“一辆汽车从伦敦的某条街道起飞，在其他随意一条街道上降落，这种事情是不大可能发生的。”
