Mark your answers on ANSWER SHEET 1. 40 The big identity-theft bust last week was just a taste of whats to come. Heres how to protect your good name. HERE

20、S THE SCARY THING about the identity-theft ring that the Feds cracked last week: there was nothing any of its estimated 40, 000 victims could have done to prevent it from happening. This was an inside job, according to court documents. A lowly help-desk worker at Teledata Communications, a software

21、firm that helps banks access credit reports online, allegedly stole passwords for those reports and sold them to a group of 20 thieves at $ 60 a pop. That allowed the gang to cherry-pick consumers with good credit and apply for all kinds of accounts in their names. Cost to the victims: $3 million an

22、d rising. Even scarier is that this, the largest identity-theft bust to date, is just a drop in the bit bucket. More than 700, 000 Americans have their credit hijacked every year. Its one of crimes biggest growth markets. A name, address and Social Security number which can often be found on the Web

23、 is all anybody needs to apply for a bogus line of credit. Credit companies make $1.3 trillion annually and lose less than 2% of that revenue to fraud, so theres little financial incentive for them to make the application process more secure. As it stands now, its up to you to protect your identity.

24、 The good news is that there are plenty of steps you can take. Most credit thieves are opportunists , not well-organized gangs. A lot of them go Dumpster diving for those millions of “ pre-approved“ credit-card mailings that go out every day. Others steal wallets and return them, taking only a Socia

25、l Security number. Shredding your junk mail and leaving your Social Security card at home can save a lot of agony later. But the most effective way to keep your identity clean is to check your credit reports once or twice a year. There are three major credit-report outfits: Equifax (at equifax. com)

26、, Trans-Union () and Experian (experian. com). All allow you to order reports online, which is a lot better than wading through voice-mail hell on their 800 lines. Of the three, I found Trans-Unions website to be the cheapest and most comprehensive laying out state-by-state prices, rights and tips f

27、or consumers in easy-to-read fashion. If youre lucky enough to live in Colorado, Georgia, Maryland, Massachusetts, New Jersey or Vermont, you are entitled to one free report a year by law. Otherwise its going to cost $8 to $ 14 each time. Avoid services that offer to monitor your reports year-round

28、for about $ 70; thats $ 10 more than the going rate among thieves. If you think youre a victim of identity theft, you can ask for fraud alerts to be put on file at each of the three credit-report companies. You can also download a theft-report form at www. consumer, gov/idtheft, which, along with a

29、local police report, should help when irate creditors come knocking. Just dont expect justice. That audacious help-desk worker was one of the fewer than 2% of identity thieves who are ever caught. 41 What is the trend of credit-theft crime? （ A） Tightly suppressed. （ B） More frightening. （ C） Rapidl

30、y increasing. （ D） loosely controlled. 42 The expression “inside job“ (Line 3, Paragraph 2) most probably means （ A） a crime that is committed by a person working for the victim. （ B） a crime that should be punished severely. （ C） a crime that does great harm to the victim. （ D） a crime that poses a

31、 great threat to the society. 43 The creditors can protect their identity in the following ways except （ A） destroying your junk mail. （ B） leaving your Social Security card at home. （ C） visiting the credit-report website regularly. （ D） obtaining the free report from the government. 44 Why is it e

33、oss of the creditors （ C） How to protect your good name （ D） Why the creditors lose their identity 45 In the 1950s, the pioneers of artificial intelligence (AI) predicted that, by the end of this century , computers would be conversing with us at work and robots would be performing our house-work. B

34、ut as useful as computers are, theyre nowhere close to achieving anything remotely resembling these early aspirations for human like behavior. Never mind something as complex as conversation : the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of t

35、asks for a ten-month-old kid. A growing group of AI researchers think they know where the field went wrong. The problem, the scientists say, is that AI has been trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by

36、-step programs. A new movement in AI, on the other hand, takes a closer look at the more roundabout way in which naturally came up with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional computer programs. Rather than digital compu

37、ters and transistors, some want to work with brain cells and proteins. The results of these early efforts are as promising as they are peculiar, and the new nature-based AI movement is slowly but surely moving to the forefront of the field. Imitating the brains neural (神经的 ) network is a huge step i

38、n the right direction, says computer scientist and biophysicist Michael Conrad, but it still misses an important aspect of natural intelligence. “People tend to treat the brain as if it were made up of color-coded transistors“ , he explains, “but its not simply a clever network of switches. There ar

39、e lots of important things going on inside the brain cells themselves. “ Specifically, Conrad believes that many of the brains capabilities stem from the patternrecognition proficiency of the individual molecules that make up each brain cell. The best way to build and artificially intelligent device

40、, he claims, would be to build it around the same sort of molecular skills. Right now, the option that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and h

41、is fellow AI rebels could turn out to be the only game in town. 46 The author says that the powerful computers of today （ A） are capable of reliably recognizing the shape of an object. （ B） are close to exhibiting humanlike behavior. （ C） are not very different in their performance from those of the

42、 50s. （ D） still cannot communicate with people in a human language. 47 The new trend in artificial intelligence research stems from （ A） the shift of the focus of study on to the recognition of the shapes of objects. （ B） the belief that human intelligence cannot be duplicated with logical, step-by

43、-step programs. （ C） the aspirations of scientists to duplicate the intelligence of a ten-month-old child. （ D） the efforts made by scientists in the study of the similarities between transistors and brain cells. 48 Conrad and his group of AI researchers have been making enormous efforts to （ A） fin

44、d a roundabout way to design powerful computers. （ B） build a computer using a clever network of switches. （ C） find out how intelligence developed in nature. （ D） separate the highest and most abstract levels of thought. 49 Whats the authors opinion about the new AI movement? （ A） It has created a

45、sensation among artificial intelligence researchers, but it will soon die out. （ B） Its a breakthrough in duplicating human thought processes. （ C） Its more like a peculiar game rather than a real scientific effort. （ D） It may prove to be in the right direction though nobody is sure of its future p

46、rospects. 50 Which of the following is closest in meaning to the phrase “the only game in town“ (Line 3, Para. 4)? （ A） The only approach to building an artificially intelligent computer. （ B） The only way for them to win a prize in artificial intelligence research. （ C） The only area worth studying

47、 in computer science. （ D） The only game they would like to play in town. 50 Being a man has always been dangerous. There are about 105 males born for every 100 females , but this ratio drops to near balance at the age of maturity, and among 70-year-olds there are twice as many women as men. But the

48、 great universal of male mortality is being changed. Now, boy babies survive almost as well as girls do. This means that, for the first time, there will be an excess of boys in those crucial years when they are searching for a mate. More important, another chance for natural selection has been remov

49、ed. Fifty years ago, the chance of a baby (particularly a boy baby) surviving depended on its weight. A kilogram too light or too heavy meant almost certain death. Today it makes almost no difference. Since much of the variation is due to genes, one more agent of evolution has gone. There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. Except in some religious communities, very few women have 15 children. Nowadays the number of births, like the age of death, ha
