  Section III Reading Comprehension (60 minutes)

  Part A

  根据以下资料,回答41-60题:

  The big identity-theft bust last week was just a taste of what' s to come.Here' s how to protect your good name.

  HERE'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 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 and 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.It's one of crime's biggest growth markets.A name,address and Social Security number--which can often be found on the Web-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 there's little financial incentive for them to make the.application process more secure.As it stands now,it's up to you to protect your identity.

  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 Social 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),Trans-Union (www.transunion.com)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-Union's website to be the cheapest and most comprehensive-laying out state-by-state prices,

  rights and tips for consumers in easy-to-read fashion.

  If you're lucky enough to live in Colorad0,Georgia,Maryland,Massachusetts,New Jersey or Vermont,you are entitled to one free report a year by law.Otherwise it's going to cost$8 to $14 each time.Avoid services that offer to monitor your reports year-round for about$70;that's $10 more than the going rate among thieves.If you think you're 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 local police report,should help when irate creditors come knocking.Just don't 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.Rapidly increasing.

  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 great threat to the society

  A.destroying your junk mail

  B.leaving your Social Security card at home

  C.visiting the credit-report website regularly

  D.0btaining the free report from the government

  44、 Why is it easy to have credit-theft?

  A.More people are using credit service.

  B.The application program is not safe enough.

  C.Creditors usually disclose their identity.

  D.Creditors are not careful about their identity.

  45、 What is the best title of the text?

  C.How to protect your good name

  D.Why the creditors lose their identity

  根据以下资料,回答46-65题:

  In the l950s,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.But as useful as computers are,they're 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 tasks for a ten-month-old kid.

  A growing group of AI researchers think they know where the field went wrong.The prob-lem,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-step pro-grams.A new movement in Al,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 computers and transistors.some want to work。with brain cells and proteins.The results of these early ef-forts 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.

  mitating the brain's neural(神经的)network is a huge step in 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 it's not simply a clever network of switches.There are lots of important things going on inside the brain cells themselves."Specifically.Conrad believes that many of the brain's capabilities stem from the pattern recognition proficiency of the individual molecules that make up each brain cell.The best way to build and artificially intelligent device,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 his 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 50's

  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-step pro-grams

  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.find 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、 What's the author's opinion about the new AI movement?

  A.It has created a sensation among artificial intelligence researchers,but it will soon die out.

  B.It's a breakthrough in duplicating human thought processes.

  C.It's 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 prospects.

  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 all artificially intelligent computer.

  B.The only way for them to win a prize in artificial intelligence。research.

  C.The only area worth studying in computer science.

  D.The only game they would like to play in town.
