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 airstrips. 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
【C4】
选项
答案B
解析 动词辨析题。空格位于系动词和介词之间，填入形容词、动词的现在分词和过去分词都可以。空格后出现了and，and后面的picked叩为过去分词用作被动语态。由于and连接平行结构，故空格处也应填动词的过去分词且能和介词from搭配，故选择B项detached，“be detached from…”意为“从……脱离，和……分开”。M项segmented虽然语法上说得通，但它的意思是“分割，划分”，强调的是把一个整体分割成若干部分，常搭配介词into，故排除。
