问题     Automakers are doing all sorts of things to cars to make them smarter and more autonomous, as regular readers are aware. Here’s a new one: General Motors(GM)wants to take self-parking cars to a new level, letting them drop off their drivers and go off in【S1】_____of empty spaces on their own. It’ll be more fuel-efficient than having humans circle the block waiting for a【S2】_____to open up, GM says.
    Fuel efficiency is one of the promised benefits of【S3】_____intelligent cars, which could cut down on fuel【S4】_____by predicting where drivers will go and re-routing around predicted traffic jams. Smarter cars could also【S5】_____with each other, preventing collisions and congestion.
    We have seen several self-parking car concepts, and GM has【S6】_____the technology with its EN-V concept, says Technology Review. This new concept lets the driver hop out, leaving the car to drive itself to the nearest【S7】_____empty space—even if that’s several blocks or even miles away. When it’s time to leave, the driver can【S8】_____his or her car via a smartphone app, and it will reappear KITT-style to whisk(快速带走)its driver away.
    For anyone who has ever tried to park in, say, New York or San Francisco, this sounds mighty【S9】_____But would you trust your empty car to go find a safe spot to bide(等待)its time while you go about your business? In some ways that may be a greater【S10】_____than the technology itself.
A)spot F)available K)memory
B)handy G)rejected L)extensively
C)conservation H)increasingly M)summon
D)challenging I)communicate N)search
E)leap J)demonstrated O)consumption
【S4】
选项
答案O
解析 名词辨析题。分析句子结构可知，空格处应填入名词，与fuel连用作cut down on的宾语。本句前半句提到智能汽车的优点之一是节省燃油，后半句进一步介绍智能汽车如何减少油耗。在备选名词中，只有consumption“消耗量；消费”符合文意。fuel consumption意为“燃油消耗”，cut down on意为“减少，削减”。
