閱讀下列短文, 從所給的四個選項中, 選出最佳答案

　Electricity is such a part of our everyday life and so much taken for granted nowadays that we hardly think twice when we switch on the light or turn on the radio．At night, roads are brightly lit, enabling people and traffic to move freely ．Colourful street-lights have become part of the character of every modern city．In the home, many labour saving devices are powered by electricity． Even when we turn off the lamp and are fast asleep, electricity is still working for us, driving our ice-boxes, heating our water, or keeping our rooms warm in winter．Every day, trains and trolleybuses take people to and from work．We rarely stop to think why or how they run until something goes wrong．

　In the summer of 1959, something did go wrong with power station that supplies New York with electricity．For a great many hours, lift came almost to standstill（停止）．Trains refused to move and the people in them sat in the dark, powerless to do anything ; lifts stopped working so that even if you were lucky enough not to be trapped（陷入）between two floors, you had the unpleaseant task（任務）of finding your way down hundreds of flights of stairs．Famous streets like Broadway and Fifth Avenue in an instant became as dark as the most distant back streets．

　People were afraid to leave their houses, for although the police had been ordered to stand by in case of （以免）emergency（緊急情況）they were just as puzzled and helpless as anybody else．

　At the same time, similar disorder happened in the home．New York can be very hot in summer and this year was no exception．Cool rooms became hot stoves．Food went bad in ice- boxes．Fish and meat remained uncooked in cooking pots, and people sat impatient and frightened in the dark as if an unseen enemy had landed from Mars（火星）, The only people who were not troubled by the darkness were the blind．Only one of the strangest things that took place was that some fifty blind people led many sighted workers home．When the lights came on again, hardly a person in the city can have turned on a switch without thinking how great a servant he bad at his finger-tips．
