填空题False Fear of Big Fish Many people believe sharks (鲨鱼)are dangerous and will always try to hurt or even kill humans. (46) A shark exhibition at the National Aquarium (水族馆) in Baltimore, US, proves this. Visitors can touch young sharks, see their eggs develop and watch a dozen different species swim smoothly around a huge tank. Most people fail to realize that shark attacks don't happen very often. Humans are more likely to be killed by lightning than by a shark. (47) There, kids can learn, from an early age, not to fear sharks. "People fear what they don't know,"said Nancy Hotchkiss, an organizer of the exhibition. "Sharks have been around for 400 million years and play an important role in the ocean's food chain. We want people to discover that sharks are amazing animals that need our respect and protection. " (48) A study, published in January in the US magazine, Science, found that almost all recorded shark species have fallen by half in the past 8 to 15 years. Thousands of sharks are hunted in Asia for special foods, such as shark fin (鱼翅) soup. And many others get caught in nets, while fishermen are hunting other fish. (49) "Some fishing methods are actually cleaning out the ocean for sharks,"said Dave Schofield, the manager of the aquarium's ocean health programme. (50) A. They can watch them develop inside their eggs and feel the skin of the older swimmers.B. A shocking 100 million sharks are killed every year around the world by humans.C. In fact, 94 percent of the world's 400 species are harmless to humans.D. It is a worrying situation and some areas have put measures in place to protect these special fish.E. And to make this point clear, the museum has set up a special touching pool for children.F. More than half of the sharks caught are smaller than 1 metre lon

A study by scientists at the University of Chicago Medical Center in Illinois showed that of the survival estimates for 486 terminally ill patients given by 343 doctors,{{U}} (46) {{/U}}. {{U}} (47) {{/U}}, and in some cases doctors predicted patients had five time longer to live than proved to be the case. "Doctors are inaccurate in their prognoses(预后)for terminally ill patients and the error is systematically optimistic," professor Nicholas Christakis and Dr Elizabeth Lamont said in a report in The British Medical Journal. The researchers added that doctors who knew their patients best were more likely to get it wrong. "{{U}} (48) {{/U}}...the type of systematic bias toward optimism that we have found in doctors' objective prognostic assessments may be adversely(不利地)affecting patient care," the researchers added. Instead of receiving three months of hospice care, which is considered to be the ideal,{{U}} (49) {{/U}}. Patients who thought they had longer to live also opted for more aggressive treatment instead of palliative(治标的)care, the report said. The researcher suggested doctors should get second opinions from colleagues,{{U}} (50) {{/U}}, before giving a prognosis. "Reliable prognostic information is a key determinant in both doctors' and patients' decision making," they said. A. many patients received only one month's care because of the optimistic prognosis. B. Although some error is unavoidable C. a lot of patients are eager to leave the hospital. D. only 20 percent were accurate E. particularly if they know a patient well. F. Sixty three percent of the predictions overestimated the time patients had left.

填空题 阅读下面这篇短文，短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第2～5段每段选择1个正确的小标题；(2)第27～30题要求从所给的6个选项中选择4个正确选项，分别完成每个句子。 {{B}} Attention to the Details{{/B}}1 Attention to detail is something everyone can and should do—especially in a tight job market. Bob Crossley, a human-resources expert notices this in the job applications that come across his desk every day. "It's amazing how many candidates eliminate themselves , "he says.2 "Resumes(简历)arrive with stains. Some candidates don't bother to spell the company's name correctly. Once I see a mistake, I eliminate the candidate, "Crossley concludes. "if they cannot take care of these details, why should we trust them with a job?"3 Can we pay too much attention to details? Absolutely. Perfectionists struggle over little things at the cost of something larger they work toward. "To keep from losing the forest for the trees," says Charles Garfield, associate professor at the University of California, San Francisco, "we must constantly ask ourselves how the details we're working on fit into the larger picture. If they don't, we should drop them and move to something else."4 Garfield compares this process to his work as a computer scientist at NASA. "The Apollo moon launch was slightly off-course 90 percent of the time." says Garfield. "But a successful landing was still likely because we knew the exact coordinates of our goal. This allowed us to make adjustments as necessary. "Knowing where we want to go helps us judge the importance of every task we undertake.5 Too often we believe what accounts for others' success is some special secret or a lucky break (机遇). But rarely is success so mysterious. Again and again, we see that by doing little things within our grasp well, large rewards follow.

填空题2. Missing the 9 - To - 5 Routine Jonathan Harris was determined to be part of the migration to the enticing (诱人的) land of high tech. (46) He lasted just seven months. He admits he was "seduced by the glamour. " realizing only later that "the fundamental economics were not good. " Translation: instead of running a rapidly growing start--up, his company was constantly short of cash and manpower. He spent his days trolling for (搜索) investment money and new employees to replace the defective old ones. Last July, Harris, 37, left the company and went back to Los Angeles--and is now looking for a job in a traditional, non--techie company. Like so many prospectors of a different epoch, workers such as Harris are discovering that "risking everything" actually involves... risk. (47) " I' ve really started to appreciate a situation where one has significant resources," Harris says. "I think folks who are blindly jumping to start--ups are undervaluing what they have. " (48) Russell Reynolds Associates, an executive--search firm, says you should have experience launching new products, be comfortable with technology and have an ability to make decisions based on incomplete information in order to succeed at an Internet firm. Otherwise, it might be wise to stay put (原位不动). Still, it' s the stock options that typically keep employees working long and faithfully at Internet start - ups, virtually handcuffed to their workstations. Author Bill Lessard, who co - wrote "Netslaves, "a firsthand account about the travails of working in Webville, says options are "basically used as a carrot to get people to give up their lives and work like lunatics (疯子) for the promise of getting rich. " (49) Gray, for example, had 20 shares of stock when she left - worth only around $ 250. Increasingly, new hires at Web firms are distressed to learn that the numbers of options they get are so paltry (不足取的) as to be insignificant. (50) A. With most market watchers predicting an eventual tech shakeout (股票市场震动), such tales of frustration and disappointment could become far more common.B. Most tech converts (皈依者) simply roll their eyes when asked about going back to what are now called "legacy" industries.C. If the promise isn' t kept, the carrot looks less tasty.D. Last year Harris left the hair - accessories firm he' d co - founded to manage a high - tech design firm called Brilliant Media in San Francisco.E. Increasingly, recruiters (招聘人员) are telling job candidates that the Web isn' t for everyone.F. They enter into a web venture with high hopes, only to find a grim reality of taxing hours, lack of support staff, greenhorn (缺乏经验的) bosses and worthless stock options.

填空题Lowering the Risk of Heart Disease Like millions of other Americans, I come from a family with a history of heart disease. My father had his first three heart attacks when he was only thirty-one. (46) I grew up with heart disease. It was there, but I didn't take it seriously. When I was thirty-one, my blood cholesterol (胆固醇) level was measured for the first time. It was 311 mg/dl, the doctor told me — an extremely high level that put me at a very high risk of heart disease, especially with my family history. He sent me to the National Institutes of Health (NIH) to be screened for participation in a clinical trial. (47) At NIH, physicians explained the degree of risk associated with my blood cholesterol level and the nature of the experiment. This test involves putting a tube through a leg artery (动脉) up to the heart. (48) Learning about the risks of the experiment as well as the risk associated with my raised blood cholesterol level scared the life out of me. Although I was excluded from participating in the study, the experience may well have saved my life. For the first time, I began to realize the seriousness of high blood cholesterol. (49) But equally important, I got a taste of what it is like to be a patient, to have tests done on me and to think of myself as sick. This was hard to take. This experience taught me two lifesaving lessons. First, although I felt fit and strong, I was actually at high risk for heart disease because of my high blood cholesterol level. And with my family history, it could not be ignored. (50) A．The death rate for the test was only 1 in 100, I was assured.B．Second, I could lower my blood cholesterol level simply by changing what I ate.C．I was three years old at that time.D．There is not enough oxygen in the blood.E．It was a heart attack just waiting to happen.F．The trial was designed to test the effect of lowering blood cholesterol on the risk of heart disease.

填空题Optimists Really Do Live Longer, Say Scientists 1. For the philosopher Arthur Schopenhauer optimism was fundamentally wrong, banal and corrupting, while the father of psychoanalysis Sigmund Freud simply declared it to be neurotic. 2. Experience shows that looking on the bright side of life does have advantages and recent scientific evidence points to the positive mindset as being beneficial to health. In other words optimists live longer. 3. That was the conclusion reached by experts at the Mayo Clinic in the US State of Minnesota who evaluated answers given by people to a set of questions in the l960s. Of the 729 candidates, 200 had died and according to scientists, there were a disproportionate number of pessimists among them. 4. Ten points more on the pessimism scale — that was the difference between "slightly pessimistic" and "averagely pessimistic" — were enough to boost a person's chances of dying by 19 percent, according to the study by prominent psychologist Martin Seligman of the University of Pennsylvania. 5. The study does not say why pessimists die but an older survey taken among children in San Francisco and Los Angeles makes it clear that personal attitude towards the world is a key factor in the longevity equation. 6. The latest evidence to support the theory that optimists tend to cope better with illness of all kinds has been provided by Professor Ralf Schwarzer of Berlin's Free University who questioned 600 heart and lung patients. His conclusion: Optimists recover more swiftly from operations than their pessimistic counterparts, tend to be happier after treatment and return to work more swiftly. 7. There have been suggestions that optimists do not stay healthier but rather turn into optimists later because they enjoy good health. Numerous surveys have taken into account a person's state of health at the outset and the effect remains the same. 8. Studies have shown that optimists do not blind themselves to reality either. They thus interpret it in a positive way. "Sublimating and denying things tend to alter reality but illusions are a way of seeing reality in the best light, " said Californian psychology professor Shelley Taylor. 9. German science journal Bild der Wissenschaft, which carries a major article on the topic in its current March issue, commented on "the right attitude" to having a tumor. 10. It seems psychotherapy can go some way towards extending the life span and life quality of a sick person although a complete recovery using psychological technique alone is unlikely. 11. Doctors like, however, to point to the example of US cycling professional Lance Armstrong, who was seriously ill with cancer, but whose unshakeable optimism helped him to take the top trophy twice at cycling's premier Tour de France. 12. The magazine also quoted a study by Sheldon Cohens of the Carnegie-Mellon-University in Pittsburgh : 420 volunteers were deliberately infected with strains of various common cold viruses. A day later checks were carried out to see who had caught a cold. 13. The results showed that in the case of people who had satisfactory, long-term relations with friends, neighbors or colleagues, the virus was less likely to trigger a cold. Of people with three or fewer firm relationships 62 percent became ill compared with only 35 percent of those who had six or more close human links.

填空题1. Psychologist George Spilich and colleagues at Washington College in Chestertown, Maryland, decided to find out whether, as many smoker say, smoking helps them "think and concentrate." Spilich put young non-smokers, active smokers and smokers deprived(被剥夺)of cigarettes through a series of tests. 2. In the first test, each subject(试验对象)sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a grouping of 96. In this simple test, smokers, deprived smokers and non-smokers performed equally well. 3. The next test was more complex, requiring all to see sequences of 20 identical letters and respond the instant one of the letters transformed into a different one. Nonsmokers were faster, but under the stimulation of nicotine(尼古丁), active smokers were faster than deprived smokers. 4. In the third test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers. 5. The fourth test required people to read a passage, then answer questions about it, Non-smokers remembered 19 percent more of the most important information than active smokers, and deprived smokers bested those who had smoked a cigarette just before testing. Active smokers tended not only to have poorer memories but also had trouble separating important information from insignificant details. 6. "As our tests became more complex." Sums up Spilich, "non--smokers performed better than smokers by wider and wider margins." He predicts, "smokers might perform adequately at many jobs--until they got complicated. A smoking airline pilot could fly adequately if no problems arose, but if something went wrong, smoking might damage his mental capacity./

填空题Napping to A Healthier Heart? Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack. The test measures levels of a protein in the blood. The researchers say people with high levels of this protein are at high risk of heart attack, heart failure or stroke. Kirsten Bibbins-Domingo of the University of California in San Francisco led the team. For about four years, they studied almost one thousand patients with heart disease. The researchers tested the heart disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack, heart failure or stroke. The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way. The study involved mostly men, so the researchers could not say for sure that the results are also true for women. They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure. Other researchers say more studies are needed to confirm if knowing the protein levels of a heart patient should affect that person"s treatment. They also would like to know if more aggressive treatment could reduce the patient"s chance of a heart attack or stroke. The study appeared in the Journal of the American Medical Association . Could a little sleep during the middle of the day reduce the risk of a heart attack? An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes. In countries like the United States, afternoon naps are mostly for children. But they are common for adults in Mediterranean countries. And these countries generally have lower rates of heart disease. So scientists in the United States and Greece wondered if naps could play a part. Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens. Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps. The researchers say napping may improve heart health by reducing stress. They say the research suggests that naps are especially good for working men. But they say not enough female subjects died during the study to judge the benefits for women.

填空题1 "All work and no play makes Jack a dull boy" is a popular saying in the United States. Other countries have similar sayings. It is true that all of us need recreation. We cannot work all the time if we are going to maintain good health and enjoy life. Good physical and mental health in fact enables us to work more efficiently. 2 Everyone has his own way of relaxing. Perhaps the most popular way is to participate in sports. There are team sports, such as baseball, basketball, and football. There are individual sports, also, such as golf and swimming. In addition, hiking, fishing, skating and mountain climbing have a great attraction for people who like to be outdoors. Chess, card-playing, and dancing are forms of indoor recreation enjoyed by many people. 3 Not everyone who enjoys sporting events likes to participate in them. Many people prefer to be spectators, either by attending the games in person, watching them on television, or listening to them on the radio. When there is an important baseball game or boxing match, it is almost impossible to get tickets; everyone wants to attend. 4 It doesn't matter whether we play a fast game of ping-pong, concentrate over the bridge table (桥牌桌), or go walking through the woods on a brisk (清闲的) autumn afternoon. It is important for everyone to relax from time to time and enjoy some form of recreation.A. The importance of having recreationB. The recreation centersC. Types of sportsD. Fun of being spectatorsE. The necessity of having recreationF. Dangers involved in playing sports

填空题Owls and Larks (锚头鹰与云雀) 1. In this article,we look at the importance of sleep for learning. Most healthy adults need eight of more hours of sleep. But why do we need sleep in the first place? We need sleep for the brain to get a chance to rebuild memories stored during the day and associate these with previously learned things. If this process is interrupted by, say, the sound of an alarm clock, it may not be as effective. So if your sleep is cut short by the alarm clock, how damaging is it? The truth is that it's difficult to predict, as so much depends on how much sleep your body actually needs on that particular occasion. 2. The popular belief that people are naturally either larks (early risers) or owls is false. The reason why people tend to be one or the other has more to do with lifestyle, age, and personality. Many people who appear to be early birds may have just become so through habit, for example, parents with very young children. Teenagers can have difficulty falling asleep until late at night and then they naturally have problems getting up the following morning. 3. "The main reason why owls are owls is that they tend to spend their time over a book, movie, or computer game till the early hours of the morning. They enjoy the quiet of the night when they can pursue their passion. On the other hand, larks can make better use of early morning hours where they can study in quiet at the time when their brains are most refreshed. So which is better for learning-an owl's or a lark's lifestyle? The simple truth is that it is more complex than simply being one or the other. Leading a well-balanced life in terms of work and play and sleeping enough to bring maximum refreshment is probably the secret. 4. As for naps,experts on insomnia (失眠) argue against taking naps, as these may keep people up at night. If your nap lasts only five minutes to half an hour and does not affect your ability to fall asleep in the night, it will probably help you be more alert in evening hours. However, if you are having problems getting to sleep at night, it's not only naps that you should avoid. Try not to drink a lot of alcohol, take nicotine(尼古丁) ,do mentally intense activities like preparing for exams or doing exercise in the evening. Some people swear that drinking coffee never stops them from sleeping like a log, whereas others will never go near the stuff for fear of being awake all night. However, the best advice for most is to avoid it in the evening, and if you drink coffee before a nap, remember you are likely to awaken as soon as the caffeine starts kicking in.A. Which is better, being an owl or a lark?B. What should we avoid?C. What helps us fall asleep?D. What makes people owls or larksE. Why do we need sleep?F. How much sleep do we need.'?

填空题Every Dog Has Its Say Kimiko Fukuda, a Japanese girl, always wondered what her dog was trying to say. Whenever she put on makeup, it would pull at her sleeve. 1 When the dog barks, she glances at a small electronic gadget(装置). The following human translation appears on its screen: "Please take me with you. I realized that"s how he was feeling," said Fukuda. The gadget is called Bowlingual, and it translates dog barks into feelings. People laughed when the Japanese toymaker Takara Company made the world"s first dog-human translation machine in 2002. But 300,000 Japanese dog owners bought it. 2 "Nobody else had thought about it," said Masahiko Kajita, who works for Takara. "We spend so much time training dogs to understand our orders; what would it be like if we could understand dogs?" Bowlingual has two parts. 3 The translation is done in the gadget using a database(资料库)containing every kind of bark. Based on animal behavior research, these noises are divided into six categories. happiness, sadness, frustration, anger, declaration and desire. 4 In this way, the database scientifically matches a bark to an emotion, which is then translated into one of 200 phrases. When a visitor went to Fukuda"s house recently, the dog barked a loud "bow wow". This translated as "Don"t come this way". 5 The product will be available in U.S. pet stores this summer for about US $120. It can store up to 100 barks, even recording the dog"s emotions when the owner is away. A. A wireless microphone is attached to the dog"s collar, which sends information to the gadget held by the owner. B. Nobody really knows how a dog feels. C. It was followed by "I"m stronger than you" as the dog growled(嗥叫)and sniffed(嗅)at the visitor. D. More customers are expected when the English version is launched this summer. E. Now, the Japanese girl thinks she knows. F. Each one of these emotions is then linked to a phrase like "Let"s play" "Look at me", or "Spend more time with me".

填空题Einstein Named "Person of the Century" Albert Einstein, whose theories on space time and matter helped unravel (解决) the secrets of the atom and of the universe, was chosen as "Person of the Century" by Time magazine on Sunday. A man whose very name is synonymous (同义的) with scientific genius, Einstein has come to represent more than any other person the flowering of 20th century scientific though that set the stage for the age of technology. "The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic, but technological--technologies that flowed directly from advances in basic science," wrote theoretical physicist Stephen Hawking in a Time essay explaining Einstein's significance. (46) Time chose as runner-up President Franklin Roosevelt to represent the triumph of freedom and democracy over fascism, and Mahatma Gandhi as an icon (象征) for a century when civil and human rights became crucial factors in global politics. "What we saw was Franklin Roosevelt embodying the great theme of freedom's fight against totalitarianism, Gandhi personifying (象征，体现) the great theme of individuals struggling for their rights, and Einstein being both a great genius and a great symbol of a scientific revolution that brought with it amazing technological advances that helped expand the growth of freedom, "said Time Magazine Editor Walter Isaacson. Einstein was born in Ulm, Germany in 1879 (47) He was slow to learn to speak and did not do well in elementary school. He could not stomach organized learning and loathed taking exams. In 1905, however, he was to publish a theory which stands as one of the most intricate examples of human imagination in history (48) Everything else mass, weight, space, even time itself — is a variable (变量). And he offered the world his now-famous equation (公式): energy equals mass times the speed of light squared — E=mc2. (49) "There was less faith in absolutes, not only of time and space but also of truth and morality." Einstein's famous equation was also the seed that led to the development of atomic energy and weapons. In 1939, six years after he fled European fascism and settled at Princeton University, Einstein, an avowed pacifist, signed a letter to President Roosevelt urging the United States to develop an atomic bomb before Nazi Germany did (50) Einstein did not work on the project. Einstein died in Princeton, New Jersey in 1955.A. "Indirectly, relativity paved the way for a new relativism in morality, art and politics," Isaacson wrote in an essay explaining Time's choices.B. How he thought of the relativity theory influenced the general public's view about Albert Einstein.C. "Clearly, no scientist better represents those advances than Albert Einstein."D.
