Question

【题目】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 (无人驾驶的) cars, which are currently in the testing stages. If the tests are successful, these electric, self-driven cars could be available very soon. But, how is it possible for a car to drive itself?

Cars already have many features allowing them to take over for drivers in certain situations. Some features include cars being able to park themselves, or slow down when they detect objects (物体) close by. They can also control the speed if there are dangerous conditions, such as snow or slippery (滑的) roads.

Other features have also changed the way drivers react to some situations. Scientists and engineers believe, with the help of wireless signals, cameras and GPS, we are now at a stage where creating a safe self-driving car might be possible.

The self-driven car may be the answer to lowering the number of deadly (致命的) accidents caused by careless drivers or dangerous conditions. However, there are still some people who do not like the idea. American lawyer Whit Drake, for example, doesn’t believe these cars are safe. He thinks the possibility of the technology making a mistake will be too high.

【1】What does the underlined phrase “take over for” in Paragraph 3 mean?

A. direct the way for B. take the place of

C. work better than D. make use of

【2】Cars already have the following features EXCEPT ________.

A. parking itself

B. controlling its speed in dangerous situations

C. slowing itself down near an object

D. avoiding car accidents one hundred percent

【3】Scientists and engineers think that ________.

A. it’s possible to make safe self-driven cars

B. it’s a long way for self-driven cars

C. there will be no drivers in the future

D. self-driven cars may cause more accidents

【4】What does the article mainly talk about?

A. Advantages of self-driven cars.

B. Different opinions on self-driven cars.

C. Possibilities of self-driven cars.

D. Google’s new technology—self-driven cars.

Answer 1

【答案】

【1】B

【2】D

【3】A

【4】C

【解析】

试题分析：短文大意：该文主要介绍了无人驾驶汽车，目前处于测试阶段，它有许多功能，很有可能成为现实。

【1】B词义猜测题。根据后文中Some features include cars being able to park themselves, or slow down when they detect objects (物体) close by. They can also control the speed if there are dangerous conditions, such as snow or slippery (滑的) roads可推知该词的意思为“代替”，所以选B。

【2】D细节理解题。根据第二段中Some features include cars being able to park themselves, or slow down when they detect objects (物体) close by. They can also control the speed if there are dangerous conditions, such as snow or slippery (滑的) roads可知一些功能包括汽车能够公园本身，或慢下来当他们检测对象(物体)。他们还可以控制速度如果有危险的情况，如雪或滑(滑)的道路。

【3】A细节理解题。根据第三段中Scientists and engineers believe, with the help of wireless signals, cameras and GPS, we are now at a stage where creating a safe self-driving car might be possible.可知科学家和工程师相信，借助无线信号、摄像机和全球定位系统(GPS)，我们现在有可能在一个阶段创建一个安全的无人驾驶汽车。所以选A。

【4】C主旨大意题。细读全文可知该文主要在介绍无人汽车目前处于测试阶段，它有许多功能，有可能成为现实，所以选C。
