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 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．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.get readers to pay attention to road safety

B.tell readers the danger of self-driven cars

C.ask readers to keep away from heavy traffic.

D.make readers be interested in self-driven cars

【2】The testing self-driven carsneed to run _________．

A.solarenergyB.water

C.electricityD.electric energy

【3】From the passage，we know that the testing self-driven carscanalready___

A.stop any accident on the road

B.turn around when getting near other cars

C.control the speed in dangerous situatuons

D.park themselves with the help of the drivers

【4】What might make the self-driven carsrunsafelyaccordingtothepassage？___

a. e-reading b. wireless signals c. cameras d. GPS

A.a, b, cB.a, b, dC.b, c, dD.a, c, d

Answer 1

【答案】

【1】D

【2】C

【3】C

【4】C

【解析】

这篇短文主要介绍了将来有可能会发明无人驾驶的汽车，以及这样的汽车将会怎样工作。如果汽车能够驱动自己，世界将是什么样的？想象一下，看到一辆空荡荡的汽车通过它的方式来接它的主人或是看见一辆装满了正在阅读，听音乐甚至是睡觉的乘客的无人驾驶汽车…车上全部的人都不担心前面的路。包括谷歌在内的几家公司正在研制无人驾驶汽车，如果测试成功的话，这些电动自驱动的汽车可以很快投入使用。汽车已经有许多能够代替驾驶员的功能，如看到物体放慢速度等．科学家和工程师相信，在无线信号、相机和全球定位系统的帮助下，我们现在创造一个安全的无人驾驶汽车是可能的。道路交通事故往往是由于司机的粗心和危险的地理位置造成的，自驱动的汽车可能够防止这些．然而，有些人不喜欢这个想法。

【1】推理判断题；根据第一段内容What would the world be like if cars could drive themselves？Imagine seeing an empty car passing by on its way …可知该段内容主要是让读者对自驾车的汽车感兴趣，故选D。

【2】细节理解题；根据短文内容But，if the tests are successful，these electric self-driven cars could be put into use very soon．可知现在仍处于测试阶段的汽车需要电能作为驱动；故选C。

【3】细节理解题；根据短文内容They can also control the speed if there are dangerous conditions．可知这种汽车在危险情况下能控制速度；故选C。

【4】细节理解题；根据短文内容 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．可知，在无线信号、相机和全球定位系统的帮助下，使得这种汽车安全行使；故选C。
