单选题Double Effect The Supreme Court's decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering. Although it ruled that there is no constitutional right to physician assisted suicide, the Court in effect supported the medical principle of "double effect", a centuries-old moral principle holding that an action having two effects—a good one that is intended and a harmful one that is foreseen—is permissible if the actor intends only the good effect. Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients' pain, even though increasing dosages will eventually kill the patient. Nancy Dubler, director of Montefiore Medical Center, contends that the principle will shield doctors who "until now have very, very strongly insisted that they could not give patients sufficient mediation to control their pain if that might hasten death. " George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. "It's like surgery," he says. "We don't call those deaths homicides because the doctors didn't intend to kill their patients, although they risked their death. If you're a physician, you can risk your patient's suicide as long as you don't intend their suicide. " On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has pro longed the physical agony of dying. Just three weeks before the Court's ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the under-treatment of pain and the aggressive use of "ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care. The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a Medicare billing code for hospital-based care, and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care. "Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering," to the extent that it constitutes"systematic patient abuse." He says medical licensing boards "must make it clear.., that painful deaths are presumptively ones that are incompetently managed and should result in license suspension. /

单选题{{B}}第三篇{{/B}} In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like "serious illness of a family member" were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stress--it only shows how much you have to deal with. And we now know that the way you handle these events dramatically affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of American who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women's magazines ran headlines like "Stress causes illness!" If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many --like the death of a loved one -- are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription(处方)for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The notion that all stress makes you sick also ignores a lot of what we know about people. It assumes we're all vulnerable (脆弱的)and passive in the face of adversity (逆 `境5. But what about human initiative and creativity? Many come through periods of stress with more physical and mental vigor than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and mental strain.

单选题Passive Smoking Is Workplace Killer Pressure mounted on Britain on Monday to take action on 1 smoking with new research showing second-hand smoke 2 about one worker each week in the hospitality industry (服务行业). Professor Knorad Jamrozik, of Imperial (帝国的) College in London, told a conference on environmental tobacco that second-hand 3 kills 49 employees in pubs, bars, restaurants and hotels each year and contributes to 700 deaths from lung cancer, heart 4 and stroke across the total national workforce. "Exposure in the hospitality 5 at work outweighs (超过) the consequences of exposure of living 6 a smoker for those staff," Jamrozik said in an interview. Other 7 have measured the levels of exposure to passive smoking but Jamrozik calculated how it would translate into avoidable deaths. His findings are 8 on the number of people working in the hospitality industry in Britain, their exposure to second-hand smoke and their 9 of dying from it. Jamrozik said the findings would apply to 10 countries in Europe because, to a greater or 11 extent, levels of smoking in the community are similar. Professor Carol Black, president of the Royal College of Physicians, which sponsored the meeting, said the research is proof of the need for a ban 12 smoking in public places. "Environmental tobacco smoke in pubs, bars, restaurants and other public places is 13 damaging to the health of employees as well as the general public," she said in a statement. "Making these places smoke-free not only protects vulnerable (易受伤害的) staff and the public, it will 14 help over 300,000 people in Britain to stop smoking completely," she added. Ireland recently became the first country to introduce a national ban on smoking in public 15 . New York and parts of Australia have taken similar measures.

单选题{{B}}第二篇{{/B}} {{B}} Valuing Childhood{{/B}} The value of childhood is easily blurred (变得模糊不清) in today's world. Consider some recent developments: The child-murderers in the Jonesboro, Ark. schoolyard shooting case were convicted and sentenced. Two boys, 7 and 8, were charged in the murder of an 11-yearold girl in Chicago. Children who commit horrible crimes appear to act of their own will. Yet, as legal proceedings in Jonesboro showed, the one boy who was able to address the court couldn't begin to explain his acts, though he tried to apologize. There may have been a motive—youthful jealousy(妒忌) and resentment. But a deeper question remains: Why did these boys and others in similar trouble apparently lack any inner, moral restraint? That question echoes for the accused in Chicago, young as they are. They wanted the girl's bicycle, a selfish impulse common enough among kids. Redemption (拯救) is a practical necessity. How can value be restored to young lives distorted by acts of violence? The boys in Jonesboro and in Chicago will be confined in institutions for a relatively short time. Despite horror at what was done, children are not—cannot be—dealt with as adults, not if a people wants to consider itself civilized. That's why politicians' cries for adult treatment of youthful criminals ultimately miss the point. But the moral void(真空)that invites violence has many sources. Family instability contributes. So does economic stress. That void, however, can be filled. The work starts with parents, who have to ask themselves whether they're doing enough to give their children a firm sense of right and wrong. Are they really monitoring their activities and their developing processes of thought? Schools, too, have a role in building character. So do youth organizations. So do law enforcement agencies, which can do more to inform the young about laws, their meaning, and their observance (遵守). The goal, ultimately, is to allow all children a normal passage from childhood to adulthood (成年), so that tragic gaps in moral judgement are less likely to occur. The relative few who fill such gaps with acts of violence hint at many others who don't go that far, but who lack the moral foundations childhood should provide — and which progressive human society relies on.

Although hot weather just makes most people hot, it can cause medical problems--and death. Health experts say that since the year 1900, extremely hot weather has killed more people in the United States than any other natural event. One year--the unusually hot summer of 1980--heat caused about 1,700 deaths in the United States. In 1995, more than 600 people died in a similar heat wave in one city--Chicago. To measure extreme heat, government weather experts have developed the Mean Heat Index. It measures the average of how hot it is felt all day on an extremely hot day. Experts say it is the total heat of a hot day or several hot days that can affect health. Several hot days are considered a heat wave. Experts say heat waves often become deadly when the nighttime temperature does not drop much from the highest daytime temperature. The most common medical problem caused by hot weather is heat stress. Usually, it also is the least severe. For most people, the only result of heat stress is muscle pain. The pain is a" warning that the body is becoming too hot. Doctors say drinking water will help the pain disappear after the body again has the right amounts of water and salt. For some people, however, the result is much more serious. For example, doctors say some people face a greatly increased danger from heat stress. These people have a weak or damaged heart, high blood pressure, or other problems of the blood system. Severe heat can help cause a heart attack or stroke. Health experts say this is the most common cause of death linked to hot weather.

单选题Abortions When Catholic clergy or "pro-life" politicians argue that abortion laws should be tightened, they do so in the belief that this will reduce the number of terminations. Yet the largest global study of abortion ever undertaken casts doubt on that simple proposition. Restricting abortions, the study says, has little effect on the number of pregnancies terminated. Rather, it drives women to seek illegal, often unsafe backstreet abortions leading to an estimated 67,000 deaths a year. A further 5m women require hospital treatment as a result of botched procedures. In Africa and Asia, where abortion is generally either illegal or restricted, the abortion rate in 2003 (the latest year for which figures are available) was 29 per 1,000 women aged 15～44. This is almost identical to the rate in Europ—28—where legal abortions are widely available. Latin America, which has some of the world"s most restrictive abortion laws, is the region with the highest abortion rate (31), while western Europe, which has some of the most liberal laws, has the lowest (12). The study, carried out by the Guttmacher Institute in New York in collaboration with the World Health Organisation (WHO) and published in a British medical journal, the Lancet , found that most abortions occur in developing countries—35m a year, compared with just 7m in rich countries. But this was largely a reflection of population size. A woman"s likelihood of having an abortion is similar whether she lives in a rich country (26 per 1,000) or a poor or middle-income one (29). Lest it be thought that these sweeping continental numbers hide as much as they reveal, the same point can be made by looking at those countries which have changed their laws. Between 1995 and 2005, 17 nations liberalized abortion legislation, while three tightened restrictions. The number of induced abortions nevertheless declined from nearly 46m in 1995 to 42m in 2003, resulting in a fall in the worldwide abortion rate from 35 to 29. The most dramatic drop—from 90 to 44—was in former communist Eastern Europe, where abortion is generally legal, safe and cheap. This coincided with a big increase in contraceptive use in the region which still has the world"s highest abortion rate, with more terminations than live births. The risk of dying in a botched abortion is only part of a broader problem of maternal health in poor countries. Of all the inequalities of development, this is arguably the worst. According to a report published this week by Population Action International, a Washington-based lobby group, women in poor countries are 250 times more likely to die in pregnancy or childbirth than women in rich ones. Of the 535,000 women who died in childbirth or from pregnancy-related complications in 2005, 99% were in developing countries, according to another report by a group of UN agencies, including WHO, also out this week. Africa accounted for more than half of such deaths. As the UN report noted, countries with the highest levels of maternal mortality have made the least progress towards reducing it. A woman in Africa has a one in 16 chance of dying in pregnancy or childbirth, compared with one in 3,800 for a woman in the rich world.
