Question

    If cars could drive themselves, what would the world be like? Imagine（设想）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（无人驾驶的）cars. So far, no Google self-driven car has gotten a traffic ticket, but some of them have been in accidents when other cars hit them. These cars are now still in the testing stages（阶段）.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 over from drivers during certain situations. Some features include cars being able to park（停车）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 signals（无线信号）, 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（阻止）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（技术）can also be mistakes.

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 D.a, c, d

【解析】

这篇短文主语讲述了无人驾驶车的优势，但也有人持不同的意见。

1.段落大意。tell readers what self-driven cars look like告诉读者什么是自驾车；tell readers to keep away from heavy traffic告诉读者远离拥挤的交通；get readers to pay attention to road safety让读者关注道路安全； make readers wonder about self-driven cars让读者对自动驾驶汽车感到好奇。根据文中“If cars could drive themselves, what would the world be like? Imagine（设想）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.” 如果汽车能自己驾驶，世界会是什么样子？想象一下（或者）看到一辆空车在去接车主的路上经过，或者看到一辆满载着正在看书、听音乐甚至睡觉的乘客的车。但他们都不担心前面的路。可知，第一段主要目的是让读者对自动驾驶汽车产生好奇。故选D。

2.词句猜测。direct the way for指引道路；take the place of代替；work better than比……工作得更好；make use of利用。根据下文“Some features include cars being able to park（停车）themselves, or slow down when they notice objects close by. They can also control the speed if there are dangerous conditions.” 一些功能包括汽车能够自行停车，或者在发现附近物体时减速。如果有危险的情况，他们也可以控制速度。可知上文是它们在某些情况下接替驾驶员，“take over from”的意思是“代替”相当于“take the place of”。根据题意，故选B。

3.细节理解。parking itself自己停车； controlling itself in dangerous situations在危险情况下控制自己；slowing itself down near an object在物体附近减速；avoiding car accidents 100% 100%避免车祸。根据文中“Some features include cars being able to park（停车）themselves, or slow down when they notice objects close by. They can also control the speed if there are dangerous conditions.” 一些功能包括汽车能够自行停车，或者在发现附近物体时减速。如果有危险的情况，他们也可以控制速度。故选D

4.细节理解。根据文中“Scientists and engineers believe, with the help of wireless signals（无线信号）, cameras and GPS, we are now at a stage where creating a safe self-driven car might be possible.”可知，借助无线信号、摄像头和GPS，我们现在正处于一个可能创造出安全的自动驾驶汽车的阶段。选项C正确。故选C。

5.主旨大意。Advantages of self-driven cars自驾车的优点； Different opinions on self-driven cars对自驾车的不同看法；Possibilities of self-driven cars自动驾驶汽车的可能性；Google's new technology-self-driven cars谷歌的新技术自动驾驶汽车。通读整篇短文可知，这篇短文主要是讲述了无人驾驶汽车的优势。故选A。
