Question

閱讀理解

　　In many businesses computers have largely replaced paperwork, because they are fast, and do not make mistakes. And they are honest. Many banks say that their business is “untouched by human hands” and therefore safe from human temptation （誘惑） . But they have no thought , and the growing number of computer crimes shows they can be used to steal.

　　Computer criminals don't use guns. And even if they are caught , it is hard to punish them because there is often no proof. A computer cannot remember who used it , it simply does what it is told. The head teller at a New York City Bank used a computer to steal more than one and a half billion. Then he moved the money from one account to another. Each time a person he had robbed questioned the balance in his account , the teller said it was a computer mistake , they replaced the missing money from someone else's account. This man was caught only because he was a gambler.

　　Some workers use the computer's power to punish their bosses they consider unfair. Recently, a large company fired its computer-record assistant for reasons that were connected with her personal life rather than her job. She was given thirty days notice. In those thirty days, she rubbed out all the company's computerized records.

　　Most computer criminals have been common workers. Now the police wonder if this is “the tip of the iceberg” . As one official says, “I have the feeling that there is more crime over there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doingthe ones who really know how a computer works. ”
