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).
According to the passage what is NOT the result after using a computer control system?
选项
A、A car would be like a train.
B、A car could be driven automatically.
C、A car would not run into another car.
D、The speed of a car could be kept steady.
答案
A
解析
文中最后一句意思是:在路边的观察者来看,一队汽车就像一列火车,车厢可以随意加入或离开。这里“车厢”即指一辆辆的汽车。因此不是一辆汽车而且是一队汽车像火车。故应选A。
