When a man is driving a car for long distances along a main road or motorway, two of his problems are to keep the car at a fairly steady speed and to make sure that he does not run into the car in front of him. Easy enough you may think—but it is even easier on a long motorway drive for a man’s attention to wander. Some experiments have been made with a system which involves computer control of these two problems. The car’s computer keeps the speed steady. At the same time the distance between the car and another car in front of it is rear reflectors(后反射镜)of the car in front and is reflected back, so enabling the distance to be measured. This information is fed to the computer, which adjusts its speed control accordingly.
There are also to be experiments with a system called "Minigap". This system will he particularly useful to driver stuck in long queues of cars, as the computer would control not only the speed and the distance from the car in front, but also the steering(方向盘操纵). Using this system, a driver could switch over to Minigap, take out his newspaper and do the crossword puzzle while car drives most of the way home automatically. To the roadside observer, the line of cars would seem like a train which carriages could join or leave at will (任意).
The word "queues"(Line 2, Para. 2)probably means______.
选项
A、trains
B、distances
C、lines
D、steering
答案
C
解析
queues所在句子的意思是:这种系统在司机被困在一长队汽车中时特别有用,它不仅控制速度和与前面车子的距离,还能控制转向。将A项trains(拖车)、B项distance(距离)、D项steering(转向)来代换queues都不合逻辑。
