单选题{{B}}第二篇{{/B}} {{B}}A Desert Between Paul and Clara{{/B}} Paul had long promised to marry Clara. But at thirty-three he met and married Alice. Clara was driven mad. Paul was taken to court. The judge ordered him to pay Clara $600 because of the broken promise. Paul had to borrow the money from a moneylender. He agreed to pay back $5 a month--for twenty years. His wages at the time were $16 a month. Paul and Alice were poor but not unhappy. They had little enough food, certainly, even before the children began to arrive. Each month Paul paid $5 to the moneylender. He worked hard, never taking a holiday. In time, there were seven mouths to feed. Illness was always with them. It grew serious when the oldest child was eight. The years of hunger weakened the family, because each month Paul paid $5. The details of the sickness were ugly, but the result was this: after twelve years of family life, Paul was alone in the world. He lived alone, except for memories. Work was not now a god for him: it was a pain-killer. Each month he paid, and in time the twenty years ended. From that moment his wages were his own. One day, it was a holiday--he went to the seaside. He sat down on a seat by the sea. A middle-aged woman came and sat down near him. They recognized each other at once. The woman said, "The $600 has been in the bank since the day it was paid to me. It is now $6,000, and I have kept it for you. Will you let me share it with you?" "No," said Paul, gently. "Each thousand is a lost life in a desert between us. It can never bring any happiness."

单选题15 Million Americans Suffer from Social Anxiety Disorder Social anxiety disorder prevents some 15 million Americans from leading normal social and romantic lives, a new survey finds. The disorder leaves many isolated, ashamed and often misdiagnosed. Thirty-six percent of those with social anxiety disorder have symptoms for 10 years or more before seeking help, the Anxiety Disorders Association of America reports. "Social anxiety disorder is when somebody has an intense, persistent and irrational fear of social or performance situations, " Jerilyn Ross, the association's president and CEO, said during a teleconference Wednesday. "The condition causes people to avoid common, everyday situations and even other people for fear of being judged or criticized or humiliated or embarrassing themselves, " Ross said. Social anxiety disorder can interfere with daily routines and job performance, Ross noted. "It also makes it very difficult for people to develop friends and romantic partnerships, " she said. People with this disorder recognize their fear is excessive and irrational, Ross noted. "But they feel powerless to do anything about it, " she said. Social anxiety disorder can start in the early teens, Dr. Mark H. Pollack, director of the Center for Anxiety and Traumatic Stress Disorders and a professor of psychiatry at Harvard Medical School, said during the teleconference. "This is a disorder that starts affecting people early on, " Pollack said. "The typical age of onset is early adolescence, age 12 or 13, and many individuals report a history of anxiety dating back to earlier childhood. " The disorder also has physical symptoms, including heart palpitations, feelings that their throat will close up, sweating, blushing, faintness, trembling and stammering, Ross said. Among people with the disorder, 75 percent said the condition affected their ability to do normal activities. In addition, 69 percent said they didn't want people to think they were crazy, and 58 percent said they were embarrassed by their condition, Ross said. However, when the condition is diagnosed and treated, many reported improvement in their lives. In fact, 59 percent who were receiving treatment said treatment had a positive effect on their ability to have a romantic relationship. In addition, 39 percent who had received treatment said knowing that treatment can be successful aided their decision to get help, Ross noted.

单选题 Hypertension Drugs Found to Cut Risk of Stroke Australian doctors declared Monday that a cocktail of simple antihypertensive drugs can lower the risk of patients suffering a repeat stroke by more than a third. This is the result of their research. The research, presented at a medical conference in Italy over the weekend, has been valued highly as a major breakthrough in stroke prevention. Strokes kill 5 million people a year, and more than 15 million suffer nonfatal strokes that often leave them with useless limbs, slurred speech and other serious disabilities. One in five stroke survivors goes on to have a second, often fatal, stroke within five years of the first. An international six-year study of 6,100 patients directed from Sydney University found that by taking two blood pressure-lowering drugs, the risk of secondary strokes can be reduced by up to 40 percent. Even taking one of the commonly available drugs can cut the risk by a third, the study said. The drugs are the diuretic indapamide and the ACE inhibitor perindopril, better known by its brand name Coversy. The combination was effective even in patients who did not have high blood pressure, the researchers said. They even found that the risk of another stroke could be cut by three quarters among the one-in-ten patients who had suffered a cerebral hemorrhage, the worst type of stroke, where there is direct bleeding into the brain. Stephen McMahon, who presented the research at the Milan congress of the European Society of Hypertension, said about 50 million people were alive who had suffered at least one stroke. "If most of those patients were able to get access to this treatment, it would result in maybe the avoidance of half a million strokes a year," the professor told Australia's ABC Radio. McMahon said doctors had long known that lowering the blood pressure of those with hypertension could help prevent strokes. "What we have shown for the first time is that it does not really matter what your blood pressure is; if you have had a stroke, then lowering blood pressure will produce large benefits, to begin with—even for people whose blood pressure is average or below average," he said. McMahon said the Milan gathering had heralded the research as a "major breakthrough in the care of patients with strokes—perhaps the biggest step forward that we have made in the last couple of decades".

单选题Late-night Drinking Coffee lovers beware. Having a quick "pick-me-up" cup of coffee late in the day will play havoc with your sleep. As well as being a stimulant, caffeine interrupts the flow of melatonin, the brain hormone that sends people into a sleep. Melatonin levels normally start to rise about two hours before bedtime. Levels then peak between 2 am and 4 am, before falling again. "It's the neurohormone that controls our sleep and tells our body when to sleep and when to wake," says Maurice Ohayon of the Stanford Sleep Epidemiology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the body's levels of this sleep hormone. Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six volunteers slept less well after a cup of caffeinated coffee than after drinking the same amount of decaf. On average, subjects slept 336 minutes per night after drinking caffeinated coffee, compared with 415 minutes after decal They also took half an hour to drop off — twice as long as usual — and jigged around in bed twice as much. In the second phase of the experiment, the researchers woke the volunteers every three hours and asked them to give a urine sample. Shilo measured concentrations of a breakdown product of melatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those in decal drinkers. In a paper accepted for publication in Sleep Medicine, the researchers suggest that caffeine blocks production of the enzyme that drives melatonin production. Because it can take many hours to eliminate caffeine from the body, Ohayon recommends that coffee lovers switch to decaf after lunch.
