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.

【4】C

【解析】

试题分析：这篇短文主要介绍了将来有可能会发明无人驾驶的汽车，及这样的汽车将会怎样工作。

【1】B 猜测词义题题。通读整篇短文可知，汽车已经有许多功能，使他们能够在某些情况下，代替驱动程序。故选B。

【2】D细节理解 根据文中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.可知，除了avoiding car accidents one hundred percent可知，没有说到避免汽车事故百分之一百，所以选D。

【3】A 细节理解题。通读整篇短文可知，制作安全自驾汽车是可能的。故选A。

【4】C主旨大意题。通读整篇短文可知，这篇短文主要讲了使用自驾汽车是可能的。故选C。
