Question

阅读理解 　　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．Obviously, computers have no reason to steal money．But they also have no conscience(良心)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 City 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(非法的)gambling operation, his name was in the records． 　　Some employees use the computer’s power to get revenge(报复)on 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 day’s notice．In those thirty days, she erased all the company’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 a 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 really know how a computer works．” (1) Which feature of computers makes computer theft possible? [　　] A． They are fast, flexible and accurate． B． They usually“feel good”． C． They have no conscience． D． They are honest． (2) It is hard to catch computer criminals because ________． [　　] A． computers forget who used them B． computer criminals seldom bear witness or leave evidence C． computer criminals don’t use weapons D． computers simply do what they are told (3) A certain head teller at a New York City bank was exposed when ________． [　　] A． his name was found in illegal gambling records B． he was replacing the missing money from someone else’s account C． a customer questioned the balance in his account D． the police broke up an illegal gambling operation (4) What conclusion can a reader draw from the passage? [　　] A． Computer criminals are minor employees． B． Of all crimes, computer theft is but“the tip of the iceberg”． C． Computer crimes are all so poorly done． D． There is more computer crime out there committed by real experts．

Answer 1

答案：1．C;2．B;3．A;4．D;
解析：

(1)	由短文第一段末句可知。
(2)	根据短文第二段第二句话可知。
(3)	根据短文第二段最后两句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可以看出，在纽约市某银行的总出纳员计算机犯罪被暴露，是由于他的名字在破获的非法赌博的记录中被发现的。
(4)	这是一道结论方面的问题。全文叙述了窃贼用计算机犯罪的情况，我们再根据短文最后一段中一位官员所说的“I have a 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 really know how a computer words”，就可以得出将会有更多的真正的计算机专家所引起的计算机犯罪的结论。
