Question

【題目】 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（特點）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（無線電的）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】

這篇短文主要介紹了將來有可能會發(fā)明無人駕駛的汽車，以及這樣的汽車將會怎樣工作。如果汽車能夠驅(qū)動自己，世界將是什么樣的？想象一下，看到一輛空蕩蕩的汽車通過它的方式來接它的主人或是看見一輛裝滿了正在閱讀，聽音樂甚至是睡覺的乘客的無人駕駛汽車…車上全部的人都不擔心前面的路。包括谷歌在內(nèi)的幾家公司正在研制無人駕駛汽車，如果測試成功的話，這些電動自驅(qū)動的汽車可以很快投入使用。汽車已經(jīng)有許多能夠代替駕駛員的功能，如看到物體放慢速度等．科學家和工程師相信，在無線信號、相機和全球定位系統(tǒng)的幫助下，我們現(xiàn)在創(chuàng)造一個安全的無人駕駛汽車是可能的。道路交通事故往往是由于司機的粗心和危險的地理位置造成的，自驅(qū)動的汽車可能夠防止這些．然而，有些人不喜歡這個想法。

【1】推理判斷題；根據(jù)第一段內(nèi)容What would the world be like if cars could drive themselves？Imagine seeing an empty car passing by on its way …可知該段內(nèi)容主要是讓讀者對自駕車的汽車感興趣，故選D。

【2】細節(jié)理解題；根據(jù)短文內(nèi)容But，if the tests are successful，these electric self-driven cars could be put into use very soon．可知現(xiàn)在仍處于測試階段的汽車需要電能作為驅(qū)動；故選C。

【3】細節(jié)理解題；根據(jù)短文內(nèi)容They can also control the speed if there are dangerous conditions．可知這種汽車在危險情況下能控制速度；故選C。

【4】細節(jié)理解題；根據(jù)短文內(nèi)容 Scientists and engineers believe，with the help of wireless （無線電的）signals，cameras and GPS，we are now at a stage where creating a safe self-driven car might be possible．可知，在無線信號、相機和全球定位系統(tǒng)的幫助下，使得這種汽車安全行使；故選C。
