填空题Part 3 Questions 19-25 ·Read the following passage and choose the correct answer from A, B, C and D. More and more, the operation of our businesses, government, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purpose can reap substantial rewards. Even worse, a number of people who have done this and been caught by it have managed to get away without punishment. It is easy for computers crime to go undetected if no one checks up what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a growing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected. But it is disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommon bad luck. For example, a certain keypunch operator complained of having to stay overtime to punch extra cards. Investigating revealed that the extra cards she was being asked were for dishonest transactions. In another case, dissatisfied employees of the thief tipped off the company that has been robbed. Unlike other lawbreakers, who must leave the country, commit suicide or go to jail, computer criminals sometimes escape punishment, demanding or not only that they not be charged but that they be given good recommendations and perhaps other benefiting, their demands have been met. Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff. And so another staff computer criminal departs with just the recommendation he needs to continue his crime elsewhere.
