Narrator
Listen to part of a lecture in a computer science class.
Now get ready to answer the questions. You may use your notes to help you answer.
According to the talk, what can NOT be concluded?
Professor
All right, why don’t we get started here...how many of you own and can operate a computer? ... Two, four, six…, let’s see...nineteen; hmm, that’s quite a few of you. OK, well, we all know how popular... no, not just popular... how necessary business and family computers are becoming and how much a part of modern-day life they are now; and so today, I am going to talk about computers. But actually, I don’t intend to talk about the function and operation of computers, but about a problem that is both worrying and very dangerous: computer crime. Let’s look more closely at this modern crime.
One thing is certain: Computers and especially computer networks have created opportunities for crime that never existed before, and as a result, the police and justice departments are becoming increasingly concerned about the growing number of computer users who are gaining access to private or secret information. It’s a problem that is on the rise worldwide. Statistics are showing a trend toward more computer crimes every year.
As we all know, the information that passes through computer networks can be sensitive and dangerous if the wrong people get access to it. War Games, a 1980’s movie, illustrates this point very well. In War Games, a young, high school boy gains access to the United States’ computerized military defense system with the intention of playing a game, but ends up nearly starting a nuclear war. This theme is, of course, exaggerated... it is very unlikely that any one, much less a high school boy, could penetrate the U.S. military security system, which limits access to extremely sensitive networks within the government.
But the idea behind the movie is a disturbing one. People can and, in fact, are using their experience in operating computers to break into networks... and are causing a lot of inconveniences and, even worse, are committing crimes and exposing others to danger. The point is this: Computer crime is very real and dangerous.
Computer crime is tempting for two reasons: number one, some computer geniuses have trouble resisting the challenge. They just want to see if they can do it. And number two, computer crime sometimes has some very significant rewards.
选项
A、There are more and more computer crimes nowadays.
B、The expertise in computer operation can sometimes lead to crimes.
C、People commit computer crimes to challenge modern technology.
D、The police and justice departments are worried about computer crimes.
答案
C
解析
本题为要点题,要求考生能综观全局,并通过综合分析来确定听力材料的要点。A项说现今的网络犯罪事件越来越多;B项说电脑操作的专业技术有时会导致犯罪的发生;C项说人们进行电脑犯罪的目的是为挑战现代技术;D项说警察及司法机关对电脑犯罪感到担忧。A、B、D三项的内容很容易从材料中听出来或得出结论,而从最后教授提到的电脑犯罪的两个原因中可知C项与材料不符,故选择C项。
