Question

【题目】根据短文内容，选择最佳答案。
What would the world be like if cars could drive themselves? Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them are worried about the road ahead.
Well, all of this could be the future of driving. There are several companies, including Google, working on driverless cars. So far, no Google self-driven car has gotten a traffic ticket, bus some of them have been in accidents when other cars hit them.
These cars are now still in the testing stages. But, if the tests are successful, these electric self-driven cars could be put into use very soon.
The cars already have many features（特点）allowing them to take the place of drivers during certain situations. Some features include cars being able to park themselves, or slow down when they notice objects close by. They can also control the speed if there are dangerous conditions.
Scientists and engineers believe, with the help of wireless（无线电的）signals, cameras and GPS, we are now at a stage where creating a safe self-driven car might be possible.
The cause of deadly road accidents is usually careless drivers or dangerous conditions. The self-driven car may be able to prevent these. However, some people do not like the idea. American lawyer Whit Drake, for example, doesn't believe these cars are safe. He thinks that technologies can also be mistakes.
（1）The main purpose of the first paragraph is to _____.
A.make readers wonder about self-driven cars
B.get readers to pay attention to road safety
C.tell readers to keep away from heavy traffic
（2）The testing self-driven cars need _____ energy to run.
A.solar
B.nuclear
C.electric
（3）From the passage, we know that the testing self-driven cars can already ______.
A.avoid being hit by other vehicles on roads
B.control the speed in dangerous situations
C.turn around when getting near objects
（4）What might make the self-driven cars run safely according to the passage?
a. e-reading b. wireless signals c. cameras d. GPS
A.a, b, c
B.a, b, d
C.b, c, d
（5）What is Whit Drake's attitude（态度）toward the safety of the self-driven cars?
A.He has doubt about it
B.He believes it completely
C.He doesn't care about it.

Answer 1

【答案】
（1）A
（2）C
（3）B
（4）C
（5）A
【解析】本文是一篇有关“无人驾驶汽车”的介绍，文中介绍了无人驾驶车辆的研究历史，无人驾驶车的原理，现在的研究成果及人们对此的不同态度等等。
（1）主旨大意题。题意：第一自然段的主要目的是什么？A. make readers wonder about self-driven cars使作者想要知道无人驾驶车；B. get readers to pay attention to road safety使读者注意道路安全；C. tell readers to keep away from heavy traffic告诉读者远离拥挤的交通。第一段描述的是无人驾驶的车辆上的快乐情境，目的是使人们对无人驾驶感兴趣，想知道是怎么一回事。故选A。
（2）细节理解题。题意：测试无人驾驶小车，需要什么能量供其运行？A. solar太阳能；B. nuclear核能；C. electric电能。由第三段中的：But, if the tests are successful, these electric self-driven cars could be put into use very soon.可知是“电动无人驾驶车”故选C。
（3）细节理解题。题意：从短文中，我们知道无人驾驶小车的测试已经可以做什么了？A, avoid being hit by other vehicles on roads避免在路上被其他交通工具撞击；B. control the speed in dangerous situations在危险的时候控制速度；C. turn around when getting near objects靠近物体时转弯。根据第四段里的：They can also control the speed if there are dangerous conditions.可知在危险时，车辆可以自己控制速度。故选B。
（4）推理判断题。题意：根据短文，什么可以使无人驾驶车辆安全行驶？a.e-reading电子阅读； b. wireless signals无线电信号；c. cameras相机；d. GPS定位系统。A. a, b, c；B. a, b, d；C. b, c, d根据倒数第二段可知，在无线电，相机和GPS的帮助下，无人加强的安全行驶成为了可能。故选C。
（5）推理判断题。题意： Whit Drake对无人驾驶小车的安全的态度是什么？A. He has doubt about it他对此感到怀疑；B. He believes it completely他完全相信；C. He doesn't care about it.他不关心。由短文最后的句子可知，他不相信这种小车是安全的，科技也会出错。故选A。
