The world’s first totally 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 subway railway. It was opened in 1969. This new line was much different from others.
The stations on the other lines need a lot of workers to sell tickets, and to check and collect them when people board or leave the trains. Startling enough, the Victoria Line is very different from that old operating system. Here a machine checks and collects the tickets, and there are no workers on the platforms.
There is only one worker on the train of the Victoria Line. The man usually just starts it. The train runs and stops automatically. It is controlled by electrical signals which are sent by the so-called "command spots". Each spot sends a certain signal. The train always moves at the speed that the command spots permit. If the command sends no signals, the train will stop by itself.
Most of the control work is done by computers. The computers fix the trains’ speeds, and send the signals to the command spots. If one train stays too long at a station, the other trains will then automatically move slower. So there is no danger of accidents on the line.
选项
A、It was opened in the 20th century.
B、It was built under the busy streets of London.
C、A lot of workers worked for the Victoria Line.
D、No one checks and collects the tickets on the platform.
答案
D
解析
判断题。通过快速浏览选项可判断,本题可能问的是地下铁Victoria Line的特征之类的情况,所以听录音时要注意短文对该地铁的介绍。Victoria Line作为世界第一条自动化铁路,无需人工卖票、检票、收票,一切由机器操作,站台也无需工作人员,这就是自动化铁路有别于传统铁路之处。抓听原文“Here a machine checks and collects the tickets,and there are no workers on the platforms.”可知,正确答案为D。
