问题     More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can reap big reward. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment.
    It’s easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers.
    Of course, we have no statistics on crimes that go undetected. But it’s 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 uncommonly bad luck.
    Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, 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 (诈骗) the most confidential (保密) records right under the noses of the company’s executives, accountants, and security staff. And so, another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere.
It can be concluded from the passage that________.

选项 A、it is still impossible to detect computer crimes today
B、people commit computer crimes at the request of their company
C、computer criminals escape punishment because they can’t be detected
D、computer crimes are the most serious problem in the operation of financial institutions

答案D

解析 事实细节题。第二段第一句表明,如果没有人检查计算机在做什么,那么计算机犯罪很容易不被发现。由此可知,计算机犯罪是可以被察觉的,故同时排除A项和C项;第一段第二句提到,人们是为了自己的目的修改计算机信息,故排除B项。第一段第一句提到,企业、政府和金融机构的运作越来越受到只存在于计算机内存中的信息的控制。也就是说,修改计算机信息的计算机犯罪对金融机构运作的影响越来越大,故D项为答案。
