Questions 56 to 63 are based on the following passage. In many businesses, computers have largely replaced paperwork, because they are fast, flexible, and do not make mistakes. As one banker said, “Unlike humans, computers never have a bad day.” And they are honest. Many banks advertise that their transactions are “untouched by human hands” and therefore safe from human temptation (诱惑). Obviously, computers have no reason to steal money. But they also have no conscience (良知), 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 are no witness and often no evidence. A computer cannot remember who used it: it simply does what it is told. The head teller at a New York bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this theft because he moved the money from one account to another. Each time a customer he had robbed questioned the balance in his account, the teller claimed a computer error, then replaced the missing money from someone else’s account. This man was caught only because he was a gambler. When the police broke up an illegal gambling operation, his name was in the records. Some employees use the computer’s power to get revenge (报复) on their employers they consider unfair. Recently, a large insurance company fired its computer-tape librarian for reasons that involved her personal rather than her professional life. She was given thirty days notice. In those thirty days, she erased all the firm’s computerized records. Most computer criminals have been minor employees. Now police wonder if this is “the tip of the iceberg”. As one official says, “I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing — the ones who know how a computer works.” Questions: Sometimes an unfairly-treated employee can use the computer to ________ on his employer.
Questions 46 to 50 are based on the following passage. Ron Barrister awoke once again with a slight ringing in his ears. After he showered and dressed, the condition got worse. He was also short of breath. When he looked in the mirror to see if his tongue were coated or if there were some other signs of a cold coming on, he noticed that his eyes looked peculiar. He turned sideways and looked again. Sure enough, his eyes seemed to be bulging out. He decided to explain his symptoms to Dr. Klien, the eye, ear, nose, and throat specialist. Dr. Klien examined Ron very carefully. After a complete examination he was stumped. Everything appeared normal and tests showed no signs of disorder. “Ron,” he said, “I really can’t find anything wrong, and I’m at a loss to explain your strange symptoms. However if you’d like another consultation, Dr. Brown is next door. She might be able to discover something I missed.” After another full examination, even Dr. Brown was stumped. “I can think of nothing to tell you except that you should be admitted to the hospital for a closer examination.” When Ron was being admitted to the hospital, the nurse asked him, “What size pajamas do you wear, Mr. Barrister” “I really don’t know,”he replied. “Well, do you know your shirt size” she asked as she reached for a measuring tape. “Yes,” answered Ron, “I wear 15.5 collar with a ...” The nurse measured his neck and said, “You mean a 16.5, don’t you” “No,” answered Ron, “I’ve always worn a 15.5 collar on all my shirts.” “O.K. but if you wear a 15.5 collar with your neck size, sooner or later you’re surely going to have a ringing in your ears, bulging eyes, and you’ll be short of breath.” Questions: In handling Ron Barrister’s case, both Dr. Klein and Dr. Brown were ________
A. less observant.
B. experienced.
C. confident.
D. very observant
