C
??In many businesses, computers have largely replaced paperwork, because they are fast, effective（高效的）, 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 work is “untouched by human hands” and therefore safe from human attack. Computers have no reason to steal money. But they also have no sense, and the growing number of computer crimes (犯罪) 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 (证人) and often no proof (证据). A computer cannot remember who used it and simply does what it is told. The head teller(出纳) at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from someone else’s account (帐目)．This man was caught only because he was a gambler (赌徒). When the police broke up a gambling group, his name was in the records.
??Some workers use the computer’s power to get revenge（报复）on bosses they consider unfair. Recently, a large company fired its computer assistant (助手) for reasons that were connected with her personal rather than her professional（职业的）life. She was given thirty days’ notice. In those thirty days, she got rid of all the company’s computerized records.
??Most computer criminals have been workers in low position. Now police wonder if this is “the tip of the iceberg（冰山）”. As one of the officials says, “I have a feeling that there are more crimes 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 really know how a computer works.”

查看习题详情和答案>>I have a special rule for travel: never carry a map. Sometimes I get lost, but I usually have a good time. I can practice a new language, meet new people, and learn new customs. And I find out about different “styles” of directions every time I ask, “ How can I get to the post office?”
In Japan, most streets don’t have names; people use landmarks in their directions. For example, the Japanese will say to the travelers “Go straight down to the corner. Turn left at the big hotel and go past a market. The post office is across from the bus stop.”
In the countryside of the American Midwest, there are not mountains, so the land is very flat (平的)，in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. For example, they will say: “Go north two miles. Turn east, and then go another mile.”
People in Los Angeles, California, measure distance in time, not miles. “How far away is the post office?” you ask. “Oh”, they answer, “It’s about five minutes from here.” They don’t know how many miles away it is.
People in Greece sometimes do not even try to give directions because tourists seldom understand the Greek language. Instead, a Greek will often say, “Follow me.” Then he’ll lead you through the streets of the city to the post office.
66. The underlined word landmarks in the second paragraph means ____.
A. easily recognizable (可辨认的) objects by which one can tell one’s position
B. big markets where people can tell you how to get to the post office
C. tall buildings in front of which is the post office
D. bus stops which are near the post office you are looking for
67. From the passage we learn that in the American Midwest countryside, ____.
A. there are no buildings B. there are no landmarks
C. the fields are very flat D. there are some hills
68. Which of the following shows distance in time?
A. The Japanese. B. People in Los Angeles.
C. People in Greece. D. People in the American Midwest.
69. Why don’t the Greeks try to give directions?
A. Because they often say “Follow me.”
B. Because they will lead you to the post office.
C. Because they don’t understand any foreign language.
D. Because tourists don’t understand their language.
70. The passage tells us that ____.
