回答题：

The Case of the Disappearing Fingerprints

One useful anti-cancer drug can effectively erase the whorls and other characteristic marks that give people their distinctive fingerprints. Losing__________（51）could become troublesome. A case released online in a letter by Annals of Oncology indicates how big a__________（52） of losing fingerprints is.

Eng-Huat Tan， a Singapore-based medical doctor describes a 62-year old man who has used capecitabine to __________（53）his nasopharyngeal cancer. After three years on the__________（54）， the patient decided to visit U. S. relatives last December. But he was stopped by U. S. customs officials __________（55）4 hours after entering the country when those officials couldn"t get fingerprints from the man. There were no distinctive swirly__________（56） appearing from his index finger.

U.S. customs has been fingerprinting incoming foreign visitors for years， Tan says. Their index fingers are__________（57） and screened against digital files of the fingerprints of bad guys-terrorists and potential criminals that our federal guardians have been tasked with keeping out of the country. Unfortunately， for the Singaporean travelers， one potential__________（58）effect of his drug treatment is a smoothing of the tissue on the finger pads. __________（59）， no fingerprints.

"It is uncertain when fingerprint loss will__________（60） to take place in patients who are taking eapecitabine，" Tan points out. So he cautions any physicians who__________（61）the drug to provide their patients with a doctor"s note pointing out that their medicine may cause fingerprints to disappear.

Eventually， the Singapore traveler made it into the United States. I guess the name on his passport didn"t raise any red flags. But he"s-also now got the explanatory doctor"s note——and won"t leave home __________（62） it.

By the way， maybe the Food and Drug Administration， __________（63） approved use of the drug 11 years ago， should consider __________ （64） its list of side effects associated with this medi-cine. The current list does note that patients may experience vomiting， stomach pain and some other side effects. But no where __________（65） it mention the potential for loss of fingerprints.

0 The consumer is the focus of all retail business and it is important to appreciate how

00 consumers are influenced in their buying decisions．Most of consumers, before making a

34 purchase, gather information and evaluate with the alternatives, but the extent to which

35 they look for information depends on the type of purchase．For example, in the case of

37 purchases where the risk of making the wrong decision is greater, like buying a new

38 car, so the search for information is more important．The decision to purchase is never a

39 single decision but a number of these separate decisions, and at any time during this

40 process, consumers can change their minds about and choose an alternative route．For

41 example, although a consumer may have decided where to buy a product only to realize

42 at the last moment that this is, in fact, having the wrong choice．The price in the store may

43 be too high or the staff unhelpful．On the other hand, a lack of queues, favourable credit

请根据短文内容，回答题。

"Lucky" Lord Lucan —— Alive or Dead ？

On 8th November 1974 Lord Lucan, a British aristocrat (贵族), vanished. The day before, his children&39;s nanny had been brutally murdered and his wife had been attacked too. To this day the British public are still interested in the murder case because Lucan has never been found. Now,over 30 years later, the police have reopened the case, hoping that new DNA techniques will help solve this murder mystery.＜br＞

People suspected that "lucky", as he was called by friends, wanted to kill his wife he no longer lived with. They say that Lucan entered his old house and in the dark, killed the nanny by mistake.＜br＞

His estranged (分居的) wife heard noises, came downstairs and was also attacked, but managed to escape. Seven months after the murder, a jury concluded that Lucan had killed the nanny.＜br＞

What happened next is unclear, but there are several theories which fall into one of three categories: he may have killed himself, he could have escaped or he might have been killed. It appears that the night after the murder, "lucky" borrowed a car and drove it. Lucan&39;s friend Aspinall said in an interview that he thought Lucan had committed suicide by sinking his boat in the English Channel.＜br＞

Another version of events says that "lucky" left the blood-soaked car on the coast and took a ferry to France. He was met there by someone who drove him to safety in another country.＜br＞

However, after a time, his rescuers became worried that they would become involved in the murder too and so Lucan was killed.＜br＞

A further fascinating theory was made in the book Dead Lucky by Duncan Maclaughlin, a former detective. He believes that Lucan travelled to Goa, India, where he assumed the identity of a Mr. Barry Haplin. Lucan then lived in Goa till his death in 1996. In the end the claim turned out to be a case of mistaken identity. The man who died in 1996 was really Haplin, an ex-schoolteacher turned hippy. So what is the truth about "lucky"？ DNA testing has solved many murder cases, but who knows if it can close the book on this one.

The British public are still interested in the murder case because__________. 查看材料

A.the murder was a aristocrat.

B.the murder"s DNA has been found.

The Difference between Man and Computer

What makes people different from computer programs？ What is the missing element that our theories don&39;t yet __________ (51) for？ The answer is simple: People read newspaper stories for a reason: to learn more about __________ (52) they are interested in. Computers, on the other hand,don&39;t. In fact, computers don&39;t __________ (53) have interests; there is nothing in particular that they are trying to fred out when they read. If a computer __________ (54) is to be a model of story understanding, it should also read for a "purpose".＜br＞

请根据短文的内容，回答题。 Irradiating FoodIrradiating fruits, vegetables, pork and chicken

请根据短文的内容，回答题。

Irradiating Food

Irradiating fruits, vegetables, pork and chicken to kill insects and bacteria has been approved by the Food and Drug Administration over the past decade or so. Irradiation of other meats, such as beef and lamb, is being reviewed. Federal approval does not require that industry adopt the process,and few food processors presently offer irradiated products.＜br＞

Market studies have shown that many consumers are afraid that eating irradiated foods may cause cancer, despite scientific studies that prove the safety of treated foods. Some people argue that more severe government inspection, higher food-safety standards, and more careful-preparation practices by consumers are all that is needed to ensure that food is safe. Consequently, companies currently see no need to spend millions of dollars outfitting processing plants with the equipment necessary for a process that very few shoppers are in favor of.＜br＞

All supermarkets that sell irradiated food must label the food either directly on the packaging,or, in the case of bulk items like fruits and vegetables, by placing a sign nearby. There is no requirement for the labeling of irradiated food served by chain restaurants or hospitals that buy directly from distributors, nor any regulations for products that contain irradiated ingredients.＜br＞

Presently, the FDA allows food to be treated with three types of radiation--gamma rays,high-energy electrons, and X rays -- and sets limits on doses, depending on the type of food. The principle is that the dose to be used for a certain type of food should not exceed the amount that is sufficient to kill most harmful insects and bacteria present in it. Different types of food, because of their molecular compositions, may require different doses of radiation.＜

According to the passage， killing insects and bacteria present in foods by irradiating is not completely approved by the US government. 查看材料

阅读材料，回答题。

The Diminishing Scientific Leadership of the U, S.

With the rapid globalization of science itself (more than 40 percent of scientific Ph.D. students trained in the United States are now foreign nationals, roughly half of whom return to their countries of origin ) , the once undisputed U.S.scientific lead, whether relevant to product lead or not, is diminishing.

The competition of foreign students for positions in U.S.graduate schools has also contributed to making scientific training relatively unattractive to U.S.students, because the rapidly increasing supply of students has diminished the relative rewards of this career path. For the best and brightest from low-income countries, a position as a research assistant in the United States is attractive, whereas the best and brightest U.S.students might now see better options in other fields. Science and engineering careers, to the extent that they are opening up to foreign competition (whether imported or available through better communication ) , also seem to be becoming relatively less attractive to U.S. students.

With respect to the role of universities in the innovation process the speculative boom of the 1990s(which, among other things, made it possible to convert scientific findings into cash rather quickly ) was largely unexpected.The boom brought universities and their faculties into much closer contact with private markets as they tried to gain as much of the economic dividends from their discoveries as possible. For a while,the path between discoveries in basic science and new flows of hard cash was considerably shortened. But during the next few decades, this path will likely revert toward its more traditional length and reestablish in a healthy way, the more traditional (and more independent ) relationship between the basic research done at universities and those entities that translate ideas into products and services.

In the intervening years, another new force also greatly facilitated globalization: the rapid growth of the Internet and cheap wide-bandwidth international communication. Today, complex design activities can take place in locations quite removed from manufacturing, other business functions and the consumer. Indeed, there is now ample opportunity for real-time communication between business functions that are quite independent of their specific locations. For example, software are development, with all its changes and complications, can to a considerable extent be done overseas for a U.S.customer.Foreign call centers can respond instantly to questions from thousands of miles away.The result is that low-wage workers in the Far East and in some other countries are coming into even more direct competition with a much wider spectrum of U.S. labor: unskilled in the case of call centers; more highly skilled in the case of programmers.

根据以下材料，回答题Why is the Native Language Learnt So WellHow does it happen that childr

根据以下材料，回答题

Why is the Native Language Learnt So Well

How does it happen that children learn their mother tongue so well？ When we compare them with adults learning a foreign language， we often find this interesting fact. A little child without knowledge or experience often succeeds in a complete mastery of the language. A grown-up person with fully developed mental powers， in most case， may end up with a faulty and inexact command.

What accounts for this difference？

Despite other explanations， the real answer in my opinion lies partly in the child himself，partly in the behavior. of the people around him. In the first place， the time of learning the mother tongue is the most favorable of all， namely， the first years of life. A child hears it spoken from morning till night and， what is more important， always in its genuine form， with the right pronunciation， right intonation， right use of words and right structure. He drinks in all the words

and expressions， which come to him in a flash， ever-bubbling spring. There is no resistance: there is perfect assimilation.

Then the child has， as it were， private lessons all the year round， while an adult language-student has each week a limited number of hours， which he generally shares with others. The child has another advantage: he hears the language in all possible situations， always accompanied by the right kind of gestures and facial expressions. Here there is nothing unnatural， such as is often found in language lessons in schools， when one talks about ice and snow in Juneorscorching heat in January.

And what a child hears is generally what immediately interests him. Again and again， when his attempts at speech are successful， his desires are understood and fulfilled.

Finally， though a child"s "teachers" may not have been trained in language teaching， their relations with him are always close and personal. They take great pains to make their lessons easy.

Compared with adults learning a foreign language， children learn their native language with ease. 查看材料
