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 purpose can get in substantial rewards. 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
growing recommendation from his former employers. Of course, we
have no statistics on crime 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
inspection or other security procedures. The computer criminals who have been
caught may be the victims of uncommonly bad luck. For example,
a certain keypunch (打孔机) operator complained of having to stay overtime to punch
extra cards. Investigation revealed that the extra cards she was being asked to
punch were for dishonest transactions. In another case, dissatisfied employees
of the thief tipped off the company that was being robbed.
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 or perhaps other
benefits. All too often, their demands have been met. Why?
Bemuse 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 secretly manipulate the
most confidential records right under the noses of the company's executives,
accountants and security staff. And so another computer criminal depart with
just the recommendations he needs to continue his crimes elsewhere.

【答案解析】本题问“从第三段我们可以得出怎样的推断?”文章第三段指出,But it is disturbing to note how many of the crimes we do know about were detected by accident,not by systematic inspection or other security procedures. The computer criminals who have been caught may be the victims of uncommonly bad luck. 也就是说,究竟多少犯罪未被发现,我们无从知道。我们目前只是偶然发现,并没有通过系统的检查或采取其他防范措施。言外之意,我们的防范措施太差了,所查出的犯罪只是冰山一角。故[D]“未发现的计算机犯罪远比发现的要多得多”正确。
[A]“许多被发现的计算机犯罪者将其落网归罪于运气不佳”。文中第三段最后说被查出的计算机犯罪者也许只是些运气特别不好的人,并不是罪犯自己认为运气不好。
[B]“计算机犯罪的数量迅速增多”。文中的意思是没有被发现的计算机犯罪数量很多而不是计算机犯罪增加的数量很多。本项属于偷换概念。
[C]“大多数计算机犯罪者都很聪明,可以掩饰犯罪行为”。计算机犯罪者逍遥法外主要是因为查处不善,本文并未涉及其本身的原因。
单选题

punishment.
单选题
The word "tip off" (Line 3, Para 4) mostly probably means " ______".
A. provide secrete information
B. threaten seriously
C. investigate carefully
D. defend secretly
【正确答案】
A
【答案解析】本题问 “第四段中tip off的意思是什么?”文中第三段指出,The computer criminals who have been caught may be the victims of uncommonly bad luck. 第四段也谈到,In another case,dissatisfied employees of the thief tipped off the company that was being robbed. 这里说还有一个例子证明计算机犯罪都是偶然被抓到的,据此推断应该是由于盗窃者雇用的人对他不满向被盗公司泄漏了秘密。tip off 此处意为“泄漏消息”,故[A]“提供秘密信息”正确。
[B]“严重恐吓”。若是恐吓就不具有偶然发现的意思了。
[C]“认真调查”。与上下文的意思不符。
[D)“暗地保护”。暗地保护被盗公司也不能证明计算机犯罪分子落网的原因。
单选题
What may happen to computer criminals once they are caught?
A. With a bad reputation they can hardly find other jobs.
B. They may walk away and easily find another job.
C. They will be denied access to confidential records.
D. They must go to the court to make a speech to defend
themselves.
【正确答案】
B
【答案解析】本题问“一旦计算机犯罪者落网会怎么样?”第二段提到,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 growing recommendation from his former employers. 即如果没有人检查计算机,计算机犯罪很可能就查不出来,但是即使查出来了,犯罪者也可能逃避惩罚,并带着老板的推荐信离开公司。故[B]“他们离开公司并很容易地找到另一份工作”正确。
[A]“因为名声不好,他们很难找到工作”。文中公司为了自己的名声会慎重处理计算机犯罪者,一般不会公开,所以他们的名声不会被损害。
[C]“他们会失去接触机密文件的机会”。这一点同上,公司为了自己的名声会慎重处理计算机犯罪者,他们在作案公司不会再接触机密文件,但在其他公司还有机会。
[D]“他们必须到法庭上为自己辩护”。文中第六段说公司不敢轻易将计算机犯罪者告上法庭,担心他们在法庭上大肆宣扬他们是如何在经理主管人员、会计和安检人员的鼻子底下偷偷操纵数据的。可见计算机犯罪者不会轻易被告上法庭,也就不用在法庭上为自己辩护了。
单选题
The passage is mainly about ______.
A. why computer criminals are often able to escape punishment
B. why computer crimes are difficult to detect by systematic
inspections
C. how computer criminals manage to get recommendations from former
employers
D. why computer crimes can't be eliminated
【正确答案】
A
【答案解析】本题问“文章的主旨是什么?”文中第一段第三句话指出,Even worse,a number of people who have done this and been caught at it have managed to get away without punishment. 也就是说,许多计算机犯罪者被查出了,但却丝毫不受惩罚一走了之,点出了文章主旨。另外,第二段第二句,第五、六段都照应了这个主题。故[A]“计算机犯罪分子为什么能轻易逃避惩罚”正确。
[B]“为什么计算机犯罪很难进行系统的检测”。文中第一段提到没有针对计算机犯罪系统的检查方式,但这不是全文的中心意思,较为片面。
[C]“计算机犯罪分于如何成功地从前任老板那里获得推荐”。文中指出计算机犯罪分子通常会从前任老板那里获得良好的推荐,但这只是一个细节,并非主题。
[D]“为什么计算机犯罪不能彻底根除”。本文谈论的计算机犯罪分子轻易逃避惩罚只是计算机犯罪不能根除的部分原因,题项的说法超出了文章范围。
