单选题Moderate Earthquake Strikes England A moderate earthquake struck parts of southeast England on 28 April, 2007, toppling chimneys from houses and rousing residents from their beds. Several thousand people were left without power in Kent County. One woman suffered minor head and neck injuries. "It felt as if the whole house was being slid across like a fun-fair ride," said the woman. The British Geological Survey said the 4.3-magnitude quake struck at 8:19 a.m. and was centered under the English Channel, about 8.5 miles south of Dover and near the entrance to the Channel Tunnel. Witnesses said cracks appeared in walls and chimneys collapsed across the county. Residents said the tremor had lasted for about 10 to 15 seconds. "I was lying in bed and it felt as if someone had just got up from bed next to me," said Hendrick van Eck, 27, of Canterbury about 60 miles southeast of London. "I then heard the sound of cracking, and it was getting heavier and heavier. It felt as if someone was at the end of my bed hopping up and down." There are thousands of moderate quakes on this scale around the world each year, but they are rare in Britain. The April 28 quake was the strongest in Britain since 2002 when a 4.8-magnitude quake struck the central England city of Birmingham. The country's strongest earthquake took place in the North Sea in 1931, measuring 6.1 on the Richter scale. British Geological Survey scientist Roger Musson said the quake took place on 28 April in an area that had seen several of the biggest earthquakes ever to strike Britain, including one in 1580 that caused damage in London and was felt in France. Musson predicted that it was only a matter of time before another earthquake struck this part of England. However, people should not be scared too mush by this prediction, Musson said, as the modern earthquake warning system of Britain should be able to detect a forthcoming quake and announce it several hours before it takes place. This would allow time for people to evacuate and reduce damage to the minimum.

单选题Silent and Deadly Transient ischemic attacks(TIAS), or ministrokes, result from temporary interruptions of blood flow to the brain. Unlike full strokes, they present symptoms lasting anywhere from a few seconds to 24 hours. Rarely do they cause permanent neurological damage, but they are often precursors of a major stroke. "Our message is quite clear, "says Dr. Robert Adams, professor of neurology at the Medical College of Georgia in August. "TIAS, while less severe than strokes in the short term, are quite dangerous and need a quick diagnosis and treatment as well as appropriate follow-up to prevent future injury. " Unfortunately, ministrokes are greatly underdiagnosed. A study conducted for the National Stroke Association indicates that 2.5~ of all adults aged 18 or older(about 4.9 million people in the U.S.)have experienced a confirmed TIA. An additional 1.2 million Americans over the age of 45, the study showed, have most likely suffered a ministroke without realizing it. These findings suggest that if the public knew how to spot the symptoms of stroke, especially ministrokes ,and sought prompt medical treatment, thousands of lives could be saved and major disability could be avoided. The problem is that the symptoms of a ministroke are often subtle and passing. Nonetheless, there are signs you can look out for: Numbness or weakness in the face, arm or leg, especially on one side of the body. Trouble seeing in one or both eyes. Confusion and difficulty speaking or understanding. Difficulty walking, dizziness or loss of coordination. Severe headache with no known cause. Along with these symptoms, researchers have identified some key indicators that increase your chances of having a full-blown stroke after a TIA: if you're over 60, have experienced symptoms lasting longer than 10 minutes, feel weak and have a history of diabetes. As with many diseases, you can help yourself by changing your lifestyle. The first things you should do are quit smoking, limit your intake of alcohol to no more than a drink or two a day and increase your physical activity. Even those who suffer from high blood pressure or diabetes can improve their odds—and minimize complications if they do have a stroke—by keeping their illness under control. If you experience any of the symptoms, your first call should be to your doctor. It could be the call that saves your life.

单选题The Doctor in America Self-employed private physicians who charge a fee for each patient visit have been the norm for American medical practice. Most physicians have a contract relationship with one or more hospitals in their community. They refer their patients as needed to the hospital, which usually charges according to the number of days a patient stays and the facilities - X-rays, operating rooms, tests -he or she uses.Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service. Physicians are among the best-paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to, earn incomes of more than $100, 000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would-be physicians first attend college for four years, which can cost nearly $20, 000 a year at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can exceed $10, 000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency (住院医生实习期)in a hospital, the first year as an apprentice physician. The hours are long and the pay is relatively low. Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of each other's patients in emergencies.Physicians work long hours and must accept a great deal of responsibility. Manymedical procedures, even quite routine ones, involve risk. It is understandable thatphysicians want to be well rewarded for making decisions which can mean the difference between life and death.

单选题 Continuing Medical Education There is increasing recognition of the need for health workers to continue their education throughout their careers. Not only do health workers themselves wish to improve their own skills and competence, but the introduction of new techniques and equipment and the changes taking place in health needs and health care policies necessitate continued training. The phrase "health care" is intended to mean not just curative treatment for the sick but the whole range of provision for promoting health and preventing disease. In virtually every situation some response to this need has been made, so continuing education does take place—even though it may in many instances be ineffective or insufficient. Continuing education may be initiated by the health workers themselves, by their supervisors, by the managers of the health system, or by other agencies such as professional associations, publishers, and drug companies. The form of the continuing education may be written materials (journals, books, advertisements), meetings, courses, supervisory visits, or a variety of other methods. With this diversity of approach it is not surprising that the effectiveness of the continuing education should be variable. So it is natural that in many countries there is a concern that more continuing education should be provided and that it should be more effective. The approach suggested that to achieve this aim is to develop a "system" of continuing education. This term needs some explanation as it is capable of being interpreted in many ways. A system is not the same thing as an organization that provides continuing education. It is much more than that. It is the sum of the educational activities, the organizational structure that supports and manages those activities, the management, and the external agencies involved in the provision of health care. The system should comprise a nationwide coordinated program in which technology and resources are optimally used.

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".
