Question

【題目】

A. driving B. processes C. parking D. cameras E. passengers

So how do driver-less cars work? They have sensors（傳感器）all around which can detect other cars and obstacles on the road. Sensors on the wheels also help when 【1】, so the car knows how far it is from the outside of the road or other parked cars. Road signs are read by 【2】, and satellite navigation systems are used so the car knows how to get to your destination. All you have to do is type in the address! Finally, a central computer system takes in all the information it receives from the sensors and cameras and 【3】 this to work out when to speed up, brake and go. Sound like your idea of heaven? Sitting back, looking out of the windows and even watching a film or reading a book while 【4】 would be possible with this new technology.

【1】C

【2】D

【3】B

【4】A

【解析】

本文屬于說明文，主要介紹了無人駕駛汽車的工作原理，優(yōu)點以及存在的問題。

【1】句意：車輪上的傳感器在停車時也有幫助，因此汽車知道它離道路或其他停放的汽車有多遠。

根據(jù)“so the car knows how far it is from the outside of the road or other parked cars.”因此汽車知道它離道路或其他停放的汽車有多遠�？芍�，應(yīng)該是車輪上的傳感器在停車時也有幫助。故選C。

【2】句意：路標(biāo)由攝像頭讀取，并使用衛(wèi)星導(dǎo)航系統(tǒng)，以便汽車知道如何到達目的地。

根據(jù)“Finally, a central computer system takes in all the information it receives from the sensors and cameras and 3 this to work out when to speed up, brake and go.”最后，中央計算機系統(tǒng)接收從傳感器和攝像機接收到的所有信息，并處理這些信息，以確定何時加速、剎車和前進。可知，路標(biāo)由攝像頭讀取的。故選D。

【3】句意：最后，中央計算機系統(tǒng)接收從傳感器和攝像機接收到的所有信息，并處理這些信息，以確定何時加速、剎車和前進。

根據(jù)“work out when to speed up, brake and go.”以確定何時加速、剎車和前進�？芍�，這些是中央計算機系統(tǒng)接收從傳感器和攝像機接收到的所有信息，并處理這些信息的結(jié)果。故選B。

【4】句意：坐在后面，望著窗外，甚至在開車時看電影或看書，都有可能使用這項新技術(shù)。

由句子中的while可知，while用作連詞時，意為“當(dāng)……時候，和……同時”的意思，引導(dǎo)時間狀語從句；再結(jié)合所給的選項可知，只有選擇driving符合語境。是指“開車的同時，可以看電影或看書�！惫蔬xA。
