单选题"Don't Drink Alone" Gets New Meaning In what may be bad news for bars and pubs, a European research group has found that people drinking alcohol outside of meals have a significantly higher risk of cancer in the mouth and neck than do those taking their libations with food. Luigino Dal Maso and his colleagues studied the drinking patterns of 1,500 patients from four cancer studies and another 3.500 adults who had never had cancer. After the researchers accounted for the amount of alcohol consumed, they found that individuals who downed a significant share of their alcohol outside of meals faced at least a 50 to 80 percent risk of cancer in the oral cavity, pharynx, and esophagus, when compared with people who drank only at meals. Consuming alcohol without food also increased by at least 50 percent the likelihood of laryngeal cancer. "Roughly 95 percent of cancers at these four sites traced to smoking or drinking by the study volunteers, " Dal Maso says. The discouraging news. his team reports, is that drinking with meals didn't eliminate cancer risk at any of the sites. For their new analysis, the European scientists divided people in the study into four groups. based on how many drinks they reported having in an average week. The lowest-intake group included people who averaged up to 20 drinks a week. The highest group reported downing at least 56 servings of alcohol weekly for an average of eight or more per day. Cancer risks for the mouth and neck sites rose steadily with consumption even for people who reported drinking only with meals. For instance, compared with people in the lowest-consumption group, participants who drank 21 to 34 alcohol servings a week at least doubled their cancer risk for all sites other than the larynx. If people in these consumption groups took some of those drinks outside meals, those in the higher consumption group at least quadrupled their risk for oral cavity and esophageal cancers. People in the highest-consumption group who drank only with meals had 10 times the risk of oral cancer. 7 times the risk of pharyngeal cancer. and 16 times the risk of esophageal cancer compared with those who averaged 20 or fewer drinks a week with meals. In contrast, laryngeal cancer risk in the high-intake, with-meals-only group was only triple that in the low-intake consumers who drank with meals. "Alcohol can inflame tissues. Over time. that inflammation can trigger cancer. " Dal Maso says. He suspects that food reduced cancer risk either by partially coating digestive-tract tissues or by scrubbing alcohol off those tissues. He speculates that the reason laryngeal risks were dramatically lower for all study participants traces to the tissue's lower exposure to alcohol.

The usual fondling, cuddling and cleaning require little comment, but the position in which she holds the baby against her body when resting is rather revealing. Careful studies have shown the fact that 80 percent of mothers hold their infants in their left arms, holding them against the left side of their bodies. If asked to explain the significance of this preference most people reply that it is obviously the result of the predominance of right-handedness in the population. By holding the babies in their left arms, the mothers keep their dominant arm free for manipulations. But a detailed analysis shows that this is not the case. True, there is a slight difference between right-handed and left-handed females; but not enough to provide adequate explanation. It emerges that 83 percent of right-handed mothers hold the baby on the left side, but so do 78 percent of left-handed mothers. In other words, only 22 percent of the left-handed mothers have their dominant hands free for actions. Clearly there must be some other, less obvious explanation. The only other clue comes from the fact that the heart is on the side of the mother's body. Could it be that the sound of her heart beat is the vital factor? And in What way? Thinking along these lines it was argued that perhaps during its existence inside the body of the mother the unborn baby get used to the sound of the heart beat. If this is so, then the re-discovery of this familiar sound after birth might have a claiming effect on the infant, especially as it has just been born into a strange and frighteningly new world, if this is so then the mother would, somehow, soon arrive at the discovery that her baby is more at peace if held on the left against her heart than on the right.

单选题Alzheimer"s Disease It was a big week for Alzheimer"s disease, and not just because PBS aired The Forgetting, a first-rate documentary about Alzheimer"s worth catching in reruns if you missed it the first time. There was also a flurry of scientific news that offered hope to the families already struggling with Alzheimer"s, as well as to the baby-boom generation that"s up next. Unless something dramatic happens, the number of Americans living with this terrifying brain disease could triple, to about 16 million, over the next 50 years. There"s still no cure in sight, but there is progress on several fronts. Among them: MEGADOSE VITAMINS—Doctors knew vitamins E and C, both antioxidants, help stave off Alzheimer"s, at least in folks who haven"t already developed the disorder. What they didn"t know—but a big study involving 4,740 participants published in the Archives of Neurology showed—was that the two vitamins taken together in huge daily doses (at least 400 IU of E and more than 500 mg of C) could reduce the risk of Alzheimer"s a remarkable 78%. COMBINATION THERAPY—A yearlong study of more than 400 Alzheimer"s patients showed that two drugs that work differently on the brain"s chemistry act well together to help slow down the disease. Patients who were being treated with donepezil (sold as Aricept), an older drug that preserves the neurotransmitter acetylcholine, were also given memantine (Namenda), a new drug approved by the FDA last October that blocks overproduction of a harmful brain chemical called glutamate. The two drugs worked even better in combination than they did alone, providing substantial benefit for patients with moderate to severe Alzheimer"s, according to a report in the Journal of the American Medical Association. BRAIN IMAGINC—Finally, scientists at the University of Pittsburgh announced that they had successfully developed a procedure that allows them to peer into the brains of Alzheimer"s patients with positron emission tomography (PET) scans to see telltale plaque deposits. Before now, doctors could not track the progress of these plaques until after the patient died, when the brain could be autopsied. Using the new technique, doctors may be able to begin treatment long before the first symptoms appear. None of these advances is a magic bullet for Alzheimer"s disease. If you or your loved ones are concerned, the first step is careful evaluation by your doctor. Not all memory lapses are Alzheimer"s, and there are reversible causes of forgetfulness that can be treated if caught early. Also, remember the old adage "use it or lose it." Mental exercise—reading, doing crossword puzzles, playing chess or scrabble—is as good for preserving your mind as physical exercise is for your body.

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 tic ; 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.
