问题     Without most people realizing it, there has been revolution in office work over the last ten years. Before that time, large computers were only used by large rich companies that could afford the investment. With the advancement of technology, small computers have come onto the market which are capable of doing the work which used to be done by much larger and expensive computers, so now most smaller companies can use them.
    The main development in small computers has been in the field of word processors, or WPS as they are often called. 40% of British offices are now estimated to have a word processor and this percentage is growing fast.
    There are many advantages in using a word processor for both secretary and manager. The secretary is freed from a lot of daily work, such as re-typing letters and storing papers. He or she can use this time to do other more interesting work for the boss. From a manager’s point of view, secretarial time is being made better use of and money can be saved by doing daily jobs automatically outside office hours.
    But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that fewer secretaries will be needed. Another worry is the increasing medical problems related to work with visual display units. The case of a slow loss of sight among people using word processors seems to have risen greatly. It is also feared that if a woman works at a VDU for long hours, the unborn child in her body might be killed. Safety screens to put over a VDU have been invented but few companies in England bother to buy them.
    Whatever the arguments for or against word processors, they are a key feature of this revolution in office practice.
Ten years ago, large computers were only used by large companies because______.
选项 A、small companies did not have enough money to buy such expensive computers
B、large computers could not do the work that small companies can do today
C、large computers did not come onto the market
D、small companies did not need to use this new technology
答案A
解析 本题为事实细节题，提问的是十年前只有大公司使用大型计算机的原因是什么。根据第一段第二句“Before that time，large computers were only used hy large rich companies thatcould afford the investment”可以看出，小公司并不能承担得起这项开支。所以答案为A)。
