The world’s first completely automatic railway has been built under the busy streets of London. The railway is called the Victoria Line, and it is part of the complete London underground railway. The new Victoria Line was opened in 1969. This new line was very different from the others. The stations on the other lines need a lot of workers to sell tickets, and to check and to collect them when people leave the trains. This is all different on the Victoria Line. Here a machine checks and collects the tickets, and there are no workers on the platforms. On the train, there is only one worker. If necessary, this man can drive the train. But usually he just starts it; it runs and stops by itself. The trains are controlled by electrical signals which are sent by the so-called "command spots". The command spots are the same distance apart. Each sends a certain signal. The train always moves at the speed that the command spots allow. If the command spot sends no signals, the train will stop. Most of the control work is done by computers. The computers also fix the train’s speeds, and send the signals to the command spots. Other machines make sure that the trains are always a safe distance apart. One train may stay too long at a station; the other trains will then automatically move slower. So there is no danger of accidents on the line.
22. What happened to the London underground railway over four decades ago?
23. Who checks and collects the tickets on the Victoria Line?
24. What is the task of the one worker on the Victoria Line train?
25. What will happen on the line if each train moves at its own speed?
选项
A、To drive the train after it is started automatically.
B、To start the train and to drive it when necessary.
C、To take care of the passengers on the train.
D、To send commanding signals to the command spot.
答案
B
解析
细节推断题。短文中间部分提到,在“维多利亚线”上,每列火车上只有一位工作人员,通常只负责让火车启动,虽然他可以操纵火车,但一般情况下,火车都是自动运行的。由此可知,在“维多利亚线”上,唯一的工作人员的职责是让火车启动并在需要时进行驾驶。
