The arrival of the mass-produced car, just over a century ago, caused a(n) 【C1】______of business creation. First came the makers of cars and all the parts that go into them. Then came the garages, filling stations and all sorts of other car-dependent【C2】______: car parks, motels, out-of-town shopping centres. Now another revolution on wheels is on the【C3】______: the driverless car. Nobody is sure when it will【C4】______. Google, which is testing a fleet of autonomous cars, thinks in maybe a decade, others【C5】______longer. And, when it does, the self-driving car, like the ordinary kind, could bring【C6】______change. Just imagine. It could, for a start, save the motor industry【C7】______stagnation. Carmakers are【C8】______about signs that smartphone-obsessed teenagers these days do not【C9】______to get a driving licence and buy their first car,【C10】______their parents did. But once they are【C11】______the trouble and expense of taking lessons and【C12】______a test, young adults might rediscover the joys of the open road. Another worry for the motor industry is that car use seems to be peaking in the most congested cities.【C13】______automated cars would drive nose-to-tail,【C14】______the capacity of existing roads; and since they would be able to【C15】______their passengers and drive away, the【C16】______of parking spaces in town might not matter so much. All these trends will【C17】______the car business. But when mass-produced cars appeared, they had an impact on the whole of society. Electronics and software firms will be【C18】______the winners: 【C19】______providing all the sensors and computing power that self-driving cars will need, they will enjoy strong demand for in-car entertainment systems,【C20】______cars" occupants will no longer need to keep their eyes on the road.
单选题
【C1】
【正确答案】
A
【答案解析】解析：空格所在句大意为“汽车的出现催生了大批相关行业”，接下来两句列举一大批因此而诞生的行业，对该句进行说明。从后两句中的First和Then，all the parts和all sorts of other．．．等用词，可看出这些行业都是紧随汽车的出现而诞生，相当于突然同时出现的“爆发性增长”，A项ex-plosion“爆发，激增”符合此处语境。
【答案解析】解析：本句顺着上一句说的“没人知道这项革命何时到来”，列举了对于自动驾驶汽车何时诞生的两种看法：谷歌的看法(Google．．．thinks in maybe a decade)和其他人的看法(otherslonger)。空格处对应前面的thinks，故应该填入意思与thinks(认为)大致相当的谓语动词，故选D项reckon“认为．估计，料想”。

【C6】
【正确答案】
B
【答案解析】解析：空格所在句讲自动驾驶汽车一旦出现会带来什么变化。根据like the ordinary kind“同普通汽车一样”。回顾首段对普通汽车诞生之后带来的一系列变化，可知这里说的应该也是能产生巨大影响的变化。四个选项中只有B项profound“深远的”符合这个语义。valid“正当的，有效的”；objective“客观的”；decent“得体的”，这三项都不能跟change(变化)搭配。
【答案解析】解析：此空填入的形容词描述的是汽车制造商对后面所说现象(signs)的态度。根据teenagers．．．do not．．．get a driving licence and buy their first car这些关键信息，可推测大致是讲年轻人不买车．这对汽车制造商来说是一种不利的现象，因而他们会感到担心和忧虑，因此B项anxious“忧虑的，焦虑的”符合语义，be anxious about．．．表示“对……感到忧虑”。此外，下文的Another worry for the motor industry中的worry“忧虑。担心”也提示这里应选B项anxious。

【C9】
【正确答案】
D
【答案解析】解析：rush to do sth．表示“急着做某事”，填入此空后意为“急于考驾照去买生平的第一辆汽车”。符合此处的语境：如今的年轻人不急着去买车的话，汽车制造商就要犯愁了，因此D项rush为本题答案。
【答案解析】解析：空格处填的是该句的谓语部分，我们需推测主语they和宾语trouble and expense的关系。once“一旦”表明前半句they are．．．trouble and expense．．．是后半句young adultsmight．．．road发生的前提条件。抓住关键信息词trouble and expense和rediscover the joys，一旦麻烦和花费减少或去掉了，自然就会开心、高兴，由此判断本题选B项spared“省掉，使免遭(麻烦等)”，spare sb．sth．表示“使某人免去……”，此处意为“当上驾校并通过考试这些麻烦和费用都可省去时。年轻人可能会对康庄大道重感兴趣”。
