单选题Men Too May Suffer from Domestic Violence Nearly three in 10 men have experienced violence at the hands of an intimate partner during their lifetimes, according to one of the few studies to look (51) domestic violence and health among men. "Many men actually do experience domestic violence, although we don't hear about it (52) ," Dr. Robert J. Reid of the University of Washington in Seattle, one of the study's authors, told Reuters Health. "They often don't tell (53) we don't ask. We want to get the message out to men who (54) experience domestic violence that they are not alone and there are resources available to (55) ." The researchers asked study participants about physical abuse and non-physical (56) such as threats that made them (57) for their safety, controlling behavior (for example, being told who they could associate with and where they could go), and constant name-calling. Among men 18 to 54 years old, 14.2 percent said they had experienced intimate partner (58) in the past five years, while 6.1 percent reported domestic violence in the previous year. Rates were lower for men 55 and (59) , with 5.3 percent reporting violence in the past five years and 2.4 percent having experienced it in the past 12 months. Overall, 30. 5 percent of men younger than 55 and 26.5 percent of older men said they had been victims of (60) violence at some point in their lives. About half of the violence the men (61) was physical. However, the physical violence men reported wasn't as harsh as (62) suffered by women in a previous study; 20 percent to 40 percent of the men rated it as severe, compared to 61 percent of (63) . Men who reported experiencing domestic violence had more emotional and mental health problems (64) those who had not, especially older men, the (65) found.

单选题Cigars Instead Smoking one or two cigars a day doubles the risk of cancers of the lip, tongue, mouth and throat, according to a government study. Daily cigars also increase the risk of lung cancer and cancer of the esophagus, and increase the risk of cancer of the larynx(voice-box) six-fold, say researchers at the National Cancer Institute in Bethesda, Maryland. In addition, the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers. The health effects of smoking cigars is one of eight sections of the article Cigars: Health Effects and Trends. The researchers report that, compared with a cigarette, a large cigar emits up to 90 times as much carcinogenic tobacco-specific nitrosamines. "This article provides clear and invaluable information about the disturbing increase in cigar use and the significant public health consequences for the country," said Dr. Richard Klausner, director of the National Cancer Institute, in a statement. "The data are clear—the harmful substances and carcinogens in cigar smoke, like cigarettes, are associated with the increased risks of several kinds of cancers as well as heart and lung diseases," he added. "In other words, cigars are not safe alternatives to cigarettes and may be addictive." "To those individuals who may be thinking about smoking cigars, our advice is—don"t. To those currently smoking cigars, quitting is the only way to eliminate completely the cancer, heart and lung disease risks," warned Klausner. According to a National Cancer Institute press release, there haven"t been any studies on the health effects on nonsmokers at cigar social events, but "... a significant body of evidence clearly demonstrates an increased lung cancer risk from secondhand smoke ."

单选题下面的短文后列出了7个句子，请根据短文的内容对每个句子做出判断：如果该句提的正确信息，请选择A；如果该句提的是错误信息，请选择B；如果该句的信息文中没有提及，请选择C。 Children's Numerical Skills People appear to be born to compute. The numerical skills of children develop so early and so inexorably that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impressive accuracy—one knife, one spoon, one fork, for each of the five chairs. Soon they are capable of noting that they have placed five knives, spoons and forks on the table and, a bit later, that this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction. It seems almost reasonable to expect that if a child were secluded on a desert island at birth and retrieved seven years later, he or she could enter a second-grade mathematics class without any serious problems of intellectual adjustment. Of course, the truth is not so simple. This century, the work of cognitive psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped—or, as the case might be, bumped into—concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one. Psychologists have since demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed into finding the total. Such studies have suggested that the rudiments of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers—the idea of a oneness, a two ness, a three ness that applies to any class of objects and is a prerequisite for doing anything more mathematically demanding than setting a table—is itself far from innate.

单选题Obesity: the Scourge of the Western World Obesity is rapidly becoming a new scourge of the western world, delegates agreed at the 11th European Conference on the issue in Vienna Wednesday to Saturday. According to, statements before the opening of the conference—of 2,000 specialists from more than 50 countries—1.2 billion people worldwide are overweight, and 250 million are obese. Professor Bernhard Ludvik of Vienna General Hospital said: "Obesity is a chronic illness. In Germany, 20 percent of the people are already affected, but in Japan only one percent." But he said that there was hope for sufferers thanks to the new scientific discoveries and medication. Professor Friedrich Hopichler of Salzberg said: "We are living in the new age (but) with the metabolism of a stone-age man." "I have just been to the United States. It is really terrible. A pizza shop is springing tip on every corner. We have been overrun by fast food and Coca-Cola-ization." Many of the experts stressed that obesity was a potential killer. Hopichler said: "80 percent of all diabetics are obese, also 50 percent of all patients with high blood pressure and 50 percent with adipose tissue complaints." "10 percent more weight means 13 percent more risk of heart disease. Reducing one"s weight by 10 percent leads to 13 percent lower blood pressure." Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs. "Though the health insurance pays for surgery (such as reducing the size of the stomach) when the body-mass index is more than 40. That is equivalent to a weight of 116 kilograms for a height of 1.70 meters. One should start earlier." Ludvik said that prevention should begin in school. "Child obesity (fat deposits) correlates with the time which children spend in front of TV sets." The consequences were only apparent later on. No more than 15 percent of obese people lived to the average life expectancy for their population group.

单选题{{B}}第三篇{{/B}} {{B}} More About Alzheimer's Disease{{/B}} Scientists have developed skin tests that may be used in the future to identify people with Alzheimer's disease and may ultimately allow physicians to predict who is at risk of getting this neurological disorder. The only current means of diagnosing the disease in a living patient is a long and expensive series of tests that eliminate every other cause of dementia. "Since Alois Alzheimer described the disease nearly a century ago, people have been trying to find a way to accurately diagnose it in its early stages," said Patricia Grady, acting director of the National Institute of Neurological Disorders and Stroke in Bethesda, Maryland. "This discovery, if confirmed, could prove a big step forward in our efforts to deal with and understand the disease." Alzheimer's is the single greatest cause of mental deterioration in older people, affecting between 2.5 million and 4 million people in the United States alone. The devastating disorder gradually destroys memory and the ability to function, and eventually causes death. There is currently no known treatment for the disease. Researches discovered that the skin cells of Alzheimer's patients have defects that interfere with their ability to regulate the flow of potassium in and out of the cells. The fact that the cell defects are present in the skin suggests that Alzheimer's results from physiological changes throughout the body, and that dementia may be the first noticeable effect of these changes as the defects affect the cells in the brain, scientists said. The flow of potassium is especially critical in cells responsible for memory formation. The scientists also found two other defects that affect the cells' supply of calcium, another critical element. One test developed by researchers calls for growing skin cells in a laboratory culture and then testing them with an electrical detector to determine if the microscopic tunnels that govern the flow of potassium are open. Open potassium channels create a unique electrical signature. A spokesman for the Alzheimer's association said that if the validity of the diagnostic test can be proven it would be important development, but cautioned that other promising tests for Alzheimer's have been disappointing.

单选题Is the Tie a Necessity? Ties, or neckties, have been a symbol of politeness and elegance in Britain for centuries. But the casual Prime Minister Tony Blair has problems with them. Reports suggest that even the civil servants may stop wearing ties. So, are the famously formal British really going to abandon the neckties? Maybe. Last week, the UK's Cabinet Secretary Andrew Turnbull openly welcomed a tieless era. He hinted that civil servants would soon be free of the costliest 12 inches of fabric that most men ever buy in their lives. In fact, Blair showed this attitude when he had his first guests to a cocktail party. Many of them were celebrities (知名人士) without ties, which would have been unimaginable even in the recent past. For some more conservative British, the tie is a must for proper appearance. Earlier, Labor leader Jim Callaghan said he would have died rather than have his children seen in public without a tie. For people like Callaghan, the tie was a sign of being complete, of showing respect. Men were supposed to wear a tie when going to church, to work in the office, to a party - almost every social occasion. But today, people have begun to accept a casual style even for formal occasions. The origin of the tie is tricky. It started as something called simply a "band". The term could mean anything around a man's neck. It appeared in finer ways in the 1630s. Frenchmen showed a love of this particular fashion statement. Their neckwear (颈饰) impressed Charles II, the king of England who was exiled (流放) to France at that time. When he returned to England in 1660, he brought this new fashion item along with him. It wasn't, however, until the late 18th century that fancy young men introduced a more colorful, flowing piece of cloth that eventually became known as the tie. Then, clubs, military institutions and schools began to use colored and patterned ties to indicate the wearer's membership in the late 19th century. After that, the tie became a necessary item of clothing for British gentlemen. But now, even gentlemen are getting tired of ties. Anyway, the day feels a bit easier when you wake up without having to decide which tie suits you and your mood.

单选题Human Heart Can Make New Cells Solving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac cells throughout the life span, although the rate of new cell production slows with age. The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say. "We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with or if they could be renewed," he said. The process of renewing these ceils changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover rate decreases with age to only 0.45 percent by age 75. "If we can understand how the generation of new cardiomyocytes is regulated, it may potentially possible to develop pharmaceuticals that promote this process to stimulate regeneration after, for example, a heart attack," Frisen said. That could lead to treatment that helps restore damaged hearts. "A lot of people suffer from chronic heart failure," noted co-author Dr. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said. With this finding, scientists are "opening the door to potential therapies to having ourselves heal ourselves," Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing." But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts--whether the rate of cell turnover in diseased hearts is the same remains unknown.
