最新考研英语阅读理解模拟试题：医学（11）考研英语阅读理解模拟试题：医学（11）Depending on whom you ask，the experiment announced at a Texas medical conference last week was a potential breakthrough for infertile women，a tragic failure or a dangerous step closer to the nightmare scenario of human cloning.T here’s truth to all these points of view. Infertility was clearly the motivation when Chinese doctors used a new technique to help one of their countrywomen get pregnant. Unlike some infertile women，the 30-year-old patient produced eggs just fine，and those eggs could be fertilized by sperm. But they never developed properly，largely because of defects in parts of the egg outside the fertilized nucleus. So using a technique developed by Dr. James Grifo at New York University，Dr. Zhuang Guanglun of Sun Yat-sen University in Guangzhou took the patient’s fertilized egg，scooped out the chromosome-bearing nuclear material and put it in a donated egg whose nucleus had been removed. In this more benign environment，development proceeded normally，and the woman became pregnant with triplets who carried a mix of her DNA and her husband’s——pretty much like any normal baby.What has some doctors and ethicists upset is that this so-called nuclear-transfer technique has also been used to produce clones，starting with Dolly the sheep. The only significant difference is that with cloning，the inserted nucleus comes from a single，usually adult，cell，and theresulting offspring is genetically identical to the parent. Doing that with humans is ethically repugnant to many. Besides，for reasons that aren’t yet well understood，cloned animalsoften abort spontaneously or are born with defects；Dolly died very young，though she had seemed healthy. And because the Chinese woman’s twins were born prematurely and died （the third triplet was removed early on to improve chances for the remaining two），critics have suggested that cloning and nuclear transfer are equally risky for humans.Not likely，says Grifo. “The obstetric outcome was a disaster，” he admits，“but the embr yos were chromosomally normal. We have no evidence that it had anything to do with the procedure.” Even so，concern over potential risks is why the Food and Drug Administration created a stringent approval process for such research in 2001——a process that Grifo found so onerous that he stopped working on the technique and gave it to the researchers in China，where it was subsequently banned （but only this month，long after Zhuang’s patient became pregnant）。

考研英语阅读理解模拟试题：医学（3）The widely held assumption that people would volunteer for AIDS-tests in droves once treatment became available was wrong. 61）And the reason for that appears to be that the government has not managed to reduce the disgrace associated with AIDS，and thus with seeking out a test for it if you suspect you might be infected.To combat this，the whole basis of AIDS testing in Botswana has just been changed. The idea is to“downgrade” the process into something low-key，routine and stigma-free. 62）Until now，a potential test subject had to opt in，by asking for a test；having asked，he was given 40 minutes of counseling to make sure he really knew what he was doing before any test was carried out. The new policy is to test people routinely when they visit the doctor. That way，having a test cannot be seen as an indication that an individual believes he may be infected. The test is not compulsory，but objectors must actively opt out. Silence is assumed to be consent，and no counseling is offered—just as would be the case for any other infectious disease.This policy shift is probably just the first of many that will take place in Botswana，South Africa and other African countries that are planning the mass provision of anti-AIDS drugs in public hospitals. Dwain Ndwapi，a doctor at Botswana‘s largest AIDS clinic，thinks that there are circumstances in which testing should be compulsory. 63）Inparticular，he believes that the currently high rate of transmission from mothers to new-born children could be reduced to zero if expectant mothers were always tested—and if those who proved positive were treated with an appropriate drugs before they gave birth.Another controversial change in the air is to reduce the frequency of two costly tests of patients‘blood. Viral-load tests and CD4-cell counts both measure how acute an individual’s infection has become. That helps a patient‘s doctor to decide when to prescribe anti-retroviral. 64）But laboratory capacity in Africa is inadequate for regular testing of the millions of people that need such drugs—at least if the tests are carried out as frequently as they would be in a rich country. Less frequent testing of each individual would allow more individuals to be given at least some tests.But that must be balanced against the need to treat more people faster. Doctors in Botswana are staggered at how desperately sick many patients are when they first arrive. They had expected people to walk into clinics for AIDS tests. Instead，many come in on stretchers on the verge of death. 65）Treating the very ill takes much more time and money than giving anti-AIDS pills to relatively healthy people，and it means that these people may have been unconsciously infecting others for longer. If routine tests persuade more patients to get help before they slump on a stretcher，all the better.1. Why few people would volunteer for AIDS-test if treatment is readily prepared？[A] Because people do not know whether they need the treatment.[B] Because people could not afford to pay the expensive drugs.[C] Because people are afraid to find out that they are infected.[D] Because people cannot bear the shame the tests bring.2. According to the text，how to “downgrade” the test process？[A] By forcing those potential AIDS patient to take the test.[B] by going down to the patients‘homes to take the test.[C] by testing patients as a regular thing in their hospital visits.[D] by asking them whether they would like to have a test.3. it can be inferred from the text that[A] the new policy will be able to include every patient who visits the doctor.[B] more policy like the new one will be carried out in a lot of African countries.[C] the old policy is better than the new one in that it provides patients with counseling.[D] the silence of the patient indicates his consent to any treatment that is available.4. the purpose of reducing the frequency of two expensive blood tests is to[A] help the patients save some money for treatments.[B] enable more people to take tests of some kind.[C] make sure that patients can receive in-time treatment.[D] prevent patients from possible further infection.5. persuading patients to get treatment early will have the following advatages except[A] saving anti-AIDS pills to relatively healthy people.[B] cutting down the costs in the treatment.[C] avoiding transmitting the virus to more people.[D] shortening doctors‘treatment time.词汇注释in droves 成群结队stigma 耻辱downgrade 降级low-key 低调的expectant mother 孕妇anti-retroviral 抗病毒staggered 吃惊的inadvertently 无意中地slump 躺难句讲解1.

考研英语阅读模拟试题及答案解析（八）2
.（D）意为：除海洛因或可卡因外，许多其他物质也是有害的。
第⼀段最后⼀句指出，许多医⽣（physician）和⼼理学家常使⽤物质滥⽤⽽不是药物滥⽤这⼀概念，他们想以此说明：滥⽤像烟酒这样的物质与滥⽤海洛因和可卡因⼀样有害。
A 意为：如果⾮法使⽤，物质可能改变我们⾝体或⼤脑的功能。
第⼀段第⼀句对药物这⼀概念下了⼀个定义：从专业⾓度来讲，除⾷品以外，任何改变我们的⾝体或⼤脑功能的物质都是药物。
但是，正如第⼆句所指出的，许多⼈错误地认为药物这⼀概念仅指某种医药或嗜毒者⽤的⾮法化学药品。
B 意为：药物滥⽤仅限指⼀少部分⼈的吸毒⾏为。
C 意为：烟酒同海洛因和可卡因⼀样致命。
这⾥，fatal（致命的）⼀词太夸张了，与原⽂中所说的有害（harmfully）相去甚远。
2.（A）该词意为：普通的，⼴泛的。
事实上，由第⼆段第⼀句的冒号后部分所表达的内容，我们可以推断出该词的意思。
该句可译为：在我们⽣活的社会⾥，医⽤或社交⽤物质（药物）⼴泛存在，如：⽤阿斯匹林制⽌头痛，⽤酒交际，早晨⽤咖啡振作⼀下精神，抽⽀烟定定神（或：松弛⼀下）。
B 意为：压倒⼀切的，占主流的。
C 意为：尖锐的，尖的。
D 意为：时髦的，流⾏的。
3.（A）意为：长时间⽆节制地嗜⽤它们。
根据第⼆段第四、五句，频繁使⽤（repeated use）某种物质（药物）会使⾝体对之上瘾或形成依赖。
依赖起先表现为耐药量（tolerance）的增加：要达到满⾜，需要的剂量越来越多；停⽌服⽤后，⼀些不舒服的反应就会出现。
可见，⽤药量和⽤药时间是造成药物依赖的两个重要因素。
B 意为：仅将它们⽤于社交⽬的。
⽂章第⼆段第⼀句确实提到了像酒这样的物质可以⽤于社交⽬的，但这不等于说只有⽤于社交⽬的的物质才可以使⼈上瘾。
C 意为：将它们⼤量地⽤来治病。
量⼤仅是可能产⽣药物依赖的原因之⼀，⽽频繁使⽤也是形成药物依赖的重要条件。
D 意为：粗⼼使⽤它们⽽产⽣不良症状。

考研英语阅读理解模拟试题：医学（12）A widely heralded but still experimental cancer-fighting compound may be used someday to prevent two other major killers of Americans：heart disease and stroke. That was the implication of a remarkable report published last week in the journal Circulation by a team of researchers from Dr. Judah Folkman’s laboratory at the Children’s Hospital in Boston.The versatile compound is endostatin，a human protein that inhibits angiogenesis，the growth of new blood vessels in the body. In tests reported in 1997 by Folkman， a prominent cancer researcher who pioneered the study of angiogenesis，the drug had reduced and even eradicated tumors in laboratory mice. How？By stunting the growth of capillaries necessary for nourishing the burgeoning mouse tumors.When news of Folkman’s achievement became widely known last year，it led to wildly exaggerated predictions of imminent cancer cures. When other scientists were initially unable to duplicate those results，questions arose about the validit y of Folkman’s research. Then in February scientists at the National Cancer Institute，with guidance from Folkman，finally matched his results. Reassured，the N.C.I. gave the go-ahead for clinical trials of endostatin later this year on patients with advanced tumors.How can a drug that is apparently effective against tumors also reducethe risk of heart attack and stroke？The answer lies in the composition of plaque，the fatty deposit that builds up in arteries and can eventually clog them. Plaque consists of a mix of cholesterol，white blood cells and smooth muscle cells，and as it accumulates，a network of capillaries sprouts from the artery walls to nourish the cells. Could endostatin halt the growth of capillaries and starve the plaque？A Folkman lab team led by Dr. Karen Moulton decided to find out. The scientists put baby lab mice on a 16-week “Western diet” that was high in fat and cholesterol，then measured the plaque buildup on the walls of each aorta，the large artery that carries blood from the heart to the rest of the body. Meanwhile，they injected one group of mice with endostatin，another with a different blood-vessel inhibitor called TNP-470 and a control group with an inert saline solution. Twenty weeks later the researchers again measured plaque in the mouse aortas. The results were startling：the endostatin group averaged 85% less plaque buildup and the TNP-470 group 70% less than those in the control group.All too aware of the premature hopes raised last year after Folkman’s tumor report，the researchers have been careful not to oversell the new results. “If this finding is supported in future studies，” says Moulton，“[it could open the way for] treatments that could delay the progression of heart disease and possibly reduce the incidence of heart attacks and strokes.” But any such treatments，she stresses，are probably five to 10years away.注（1）：本文选自Time；04/19/99，p48；注（2）：本文习题命题模仿对象2004年真题Text 1；1. What did the report indicate？[A]A very important drug is now at experimental stage.[B]Heart disease and stroke are the most serious threats to Americans.[C]The tumor drug can be used for the heart disease in the future.[D]Many Americans suffer from heart disease and stroke.2. Why did the N.C.I. agree to have clinical trials of endostatin on the patients？[A]They were convinced of the Folkman’s research.[B]They can do such a research as well as Folkman.[C]The patients with advanced tumors need the drug.[D]The drug should be proved effective on humans.3. The expression “stunting the growth of capillaries”（Line 8，Paragraph 2）most probablymeans _______.[A]help the growth of capillaries[B]limit the growth of capillaries[C]improve the growth of capillaries[D]prevent the growth of capillaries4. Why can the tumor drug be used for the heart？[A]It can accumulate a network of capillaries and nourish the cells.[B]It can stop the growth of capillaries and provide no nourishment for plaque.[C]The curing method of tumor and heart disease is the same.[D]The tumor and heart disease are made up of the same substance.5. Which of the following is true according to the text？[A]Folkman’s tumor report had be en exaggerated.[B]The tumor drug is not as effective as what has been expected.[C]The new results of the research are far more encouraging.[D]Researchers still have a long way to go to make another successful experiment.答案：CADBC。

考研英语阅读理解模拟试题：医学（9）William Shakespeare described old age as “second childishness”——sans teeth，sans eyes，sans taste. In the case of taste he may，musically speaking，have been even more perceptive than he realized. A paper in Neurology by Giovanni Frisoni and his colleagues at the National Centre for Research and Care of Alzheimer’s Disease in Brescia，Italy，shows that one form of senile dementia can affect musical desires in ways that suggest a regression，if not to infancy，then at least to a patient’s teens.Frontotemporal dementia is caused，as its name suggests，by damage to the front and sides of the brain. These regions are concerned with speech，and with such “higher” functions as abstract thinking and judgment. Frontotemporal damage therefore produces different symptoms from the loss of memory associated with Alzheimer’s disease，a more familiar dementia that affects the hippocampus and amygdala in the middle of the brain. Frontotemporal dementia is also rarer than Alzheimer’s. In the past fi ve years the centre in Brescia has treated some 1，500 Alzheimer’s patients；it has seen only 46 with frontotemporal dementia.Two of those patients interested Dr Frisoni. One was a 68-year-old lawyer，the other a 73-year-old housewife. Both had undamaged memories，but displayed the sorts of defect associated with frontotemporal dementia-a diagnosis that was confirmed by brainscanning. About two years after he was first diagnosed the lawyer，once a classical music lover whoreferred to pop music as “mere noise”，started listening to the Italian pop band “883”。

考研英语阅读理解模拟题及答案：医学类(26套)Valeta Young， 81， a retiree from Lodi， Calif.， suffers from congestive heart failure and requires almost constant monitoring. But she doesn't have to drive anywhere to get it. Twice a day she steps onto a special electronic scale， answers a few yes or no questions via push buttons on a small attached monitor and presses a button that sends the information to a nurse's station in San Antonio， Texas. “It's almost a direct link to my doctor，” says Young， who describes herself as computer illiterate but says she has no problems using the equipment.Young is not the only patient who is dealing with her doctor from a distance. Remote monitoring is a rapidly growing field in medical technology， with more than 25 firms competing to measure remotely——and transmit by phone， Internet or through the airwaves——everything from patients' heart rates to how often they cough.Prompted both by the rise in health-care costs and the increasing computerization of health-care equipment， doctors are using remote monitoring to track a widening variety of chronic diseases. In March， St. Francis University in Pittsburgh， Pa.， partnered with a company called BodyMedia on a study in which rural diabetes patients use wireless glucose meters and armband sensors to monitor their disease. And last fall， Yahoo began offering subscribers the ability to chart their asthma conditions online， using a PDA-size respiratory monitor that measures lung functions in real time and e-mails the data directly to doctors.Such home monitoring， says Dr. George Dailey， a physician at the Scripps Clinic in San Diego，“could someday replace less productive ways that patients track changes in their heart rate， blood sugar， lipid levels， kidney functions and even vision.”Dr. Timothy Moore， executive vice president of Alere Medical， which produces the smart scales that Young and more than 10，000 other patients are using， says that almost any vital sign could， in theory， be monitored from home. But， he warns，that might not always make good medical sense. He advises against performing electrocardiograms remotely， for example， and although he acknowledges that remote monitoring of blood-sugar levels and diabetic ulcers on the skin may have real value，he points out that there are no truly independent studies that establish the value of home testing for diabetes or asthma.Such studies are needed because the technology is still in its infancy and medical experts are divided about its value. But on one thing they all agree： you should never rely on any remote testing system without clearing it with your doctor.注(1)：本文选自Time;8/9/2004， p101-101， 1/2p， 2c;注(2)：本文习题命题模仿对象2004年真题text 1;1.

If they did meet him， however， they'd want to shake his hand——and the remarkable thing about that would be the simple fact that so many of them could. All the people Young has helped were victims of spinal injuries， and they owe much of the mobility they have today to his landmark work.Young， 51， head of the W.M. Keck Center for Collaborative Neuroscience at Rutgers University in New Brunswick， N.J.， was born on New Year's Day at the precise midpoint of the 20th century. Back then， the thinking about spinal-cord injury was straightforward： When a cord is damaged， it's damaged. There's nothing that can be done after an injury to restore the function that was so suddenly lost. As a medical student at Stanford University and a neurosurgeon at New York University Medical Center， Young never had much reason to question that received wisdom， but in 1980 he began to have his doubts. Spinal cords， he knew， experience progressive damage after they're injured， including swelling and inflammation， which may worsen the condition of the already damaged tissue. If that secondary insult could be relieved with drugs， might some function be preserved?Young spent a decade looking into the question， and in 1990 he co-led a landmark study showing that when high doses of a steroid known as methylprednisolone are administered within eight hours of an injury， about 20% of function can be saved. Twenty percent is hardly everything， but it can often be the difference between breathing unassisted or relying on a respirator， walking or spending one's life in a wheelchair. “This discovery led to a revolution in neuroprotective therapy，”Young says.A global revolution， actually. More than 50，000 people around the world suffer spinal injuries each year， and these days， methylprednisolone is the standard treatment in the U.S. and many other countries. But Young is still not satisfied. The drug is an elixir for people who are newly injured， but the relief it offers is only partial， and many spinal-injury victims were hurt before it became available. Young's dream is to help those people too——to restore function already lost——and to that end he is studying drugs and growth factors that could improve conduction in damaged nerves or even prod the development of new ones. To ensure that all the neural researchers around the world pull together， he has created the International Neurotrauma Society， founded the Journal of Neural Trauma and established a website () that receives thousands of hits each day.“The cure for spinal injury is going to be a combination of therapies，” Young says. “It's the most collaborative field I know.” Perhaps. But increasingly it seems that if the collaborators had a field general， his name would be Wise Young.注(1)：本文选自Time;8/20/2001， p54;注(2)：本文习题命题模仿对象2004年真题text 3;1.

Something scrambles the Dna inside a nucleus， and suddenly， instead of dividing in a measured fashion， a cell begins to copy itself furiously. Unlike an ordinary cell， it never stops. But describing the process isn't the same as figuring it out. Cancer cells are so radically different from normal ones that it's almost impossible to untangle the sequence of events that made them that way. So for years researchers have been attacking the problem by taking normal cells and trying to determine what changes will turn them cancerous——always without success.Until now. According to a report in the current issue of Nature， a team of scientists based at M.I.T.'s Whitehead Institute for Biomedical Research has finally managed to make human cells malignant——a feat they accomplished with two different cell types by inserting just three altered genes into their DNA. While these manipulations were done only in lab dishes and won't lead to any immediate treatment，they appear to be a crucial step in understanding the disease. This is a “landmark paper，” wrote Jonathan Weitzman and Moshe Yaniv of the Pasteur Institute in Paris，in an accompanying commentary.The dramatic new result traces back to a breakthrough in 1983， when the Whitehead's Robert Weinberg and colleagues showed that mouse cells would become cancerous when spiked with two altered genes. But when they tried such alterations on human cells， they didn't work. Since then， scientists have learned that mouse cells differ from human cells in an important respect： they have higher levels of an enzyme called telomerase. That enzyme keeps caplike structures called telomeres on the ends of chromosomes from getting shorter with each round of cell division. Such shortening is part of a cell's aging process， and since cancer cells keep dividing forever， the Whitehead group reasoned that making human cells more mouselike might also make them cancerous.The strategy worked. The scientists took connective-tissue and kidney cells and introduced three mutated genes——one that makes cells divide rapidly; another thatdisables two substances meant to rein in excessive division; and a third that promotes the production of telomerase， which made the cells essentially immortal. They'd created a tumor in a test tube. “Some people believed that telomerase wasn't that important，” says the Whitehead's William Hahn， the study's lead author. “This allows us to say with some certainty that it is.”Understanding cancer cells in the lab isn't the same as understanding how it behaves in a living body， of course. But by teasing out the key differences between normal and malignant cells， doctors may someday be able to design tests to pick up cancer in its earliest stages. The finding could also lead to drugs tailored to attack specific types of cancer， thereby lessening our dependence ontissue-destroying chemotherapy and radiation. Beyond that， the Whitehead research suggests that this stubbornly complex disease may have a simple origin， and the identification of that origin may turn out to be the most important step of all.注(1)：本文选自Time; 08/09/99， p60， 3/5p， 2c注(2)：本文习题命题模仿对象2002年真题text 41.

Roche， 24， volunteered for the asthma experiment， she didn't expect to benefit from it——except for the $365 she'd be paid. Unlike clinical trials，in which most patients hope that an experimental therapy will help them， this study was designed just to answer a basic question： how does the way a normal lung reacts to irritants shed light on how an asthmatic lung responds? To find out， scientists led by Dr. Alkis Togias of Johns Hopkins University had Roche and other healthy volunteers inhale a drug called hexamethonium. Almost immediately Roche began to cough and feel short of breath. Within weeks her lungs failed and her kidneys shut down. On June 2 Roche died——a death made more tragic by the possibility that it was preventable. Last week the federal Office for Human Research Protections (OHRP) ruled that Hopkins's system for protecting human subjects is so flawed that virtually all its U.S.-supported research had to stop.The worst part is that Hopkins， one of the nation's premier medical institutions， is not alone. Two years ago the inspector general of the Department of Health and Human Services warned that the system safeguarding human subjects is in danger of a meltdown. The boards that review proposed studies are overburdened，understaffed and shot through with conflicts of interest. Oversight is so porous that no one knows how many people volunteer to be human guinea pigs (21 million a year is an educated guess)， how many are hurt or how many die. “Thousands of deaths are never reported， and adverse events in the tens of thousands are not reported，”says Adil Shamoo， a member of the National Human Research Protections Advisory Committee and professor at the University of Maryland. Greg Koski， head of OHRP，has called the clinical-trials system “dysfunctional.”The OHRP findings on Hopkins are nothing short of devastating. After a three-day inspection last week， OHRP concluded that the Hopkins scientists failed to get information on the link between hexamethonium and lung toxicity， even though data were available via “routine” Internet searches and in textbooks. The drug is not approved for use in humans; the hexa-methonium Togias used was labeled [F]OR LABORATORY USE ONLY. The review board， OHRP charges， never asked for data on the safety of inhaled hexamethonium in people. The consent form that Roche signed states nowhere that hexamethonium is not approved by the FDA (the form describes it as a “medication”) and didn't warn about possible lung toxicity.Hopkins itself concluded that the review board did not do all it could to protect the volunteers， and suspended all 10 of Togias's studies. Still， the university ——whose $301 million in federal grants for 2，000 human studies made it the largest recipient of government research money last year——is seething. “Hopkins has hadover 100 years of doing clinical trials，” says Dr. Edward Miller， CEO of Johns Hopkins Medicine. “We have had one death in all of those years. We would have done anything in the world to prevent that death， but [suspending the studies] seems out of proportion.” Hopkins calls the shutdown of its experiments “unwarranted，unnecessary， paralyzing and precipitous.” OHRP is letting trials continue “where it is in the best interests” of subjects. The rest of the studies can resume once Hopkins submits a plan to restructure its system for protecting research subjects. How quickly that happens， says a government spokesman， depends on Hopkins.注(1)：本文选自Newsweek; 7/30/2001， p36;注(2)：本文习题命题模仿对象2005年真题Text 1;1.

You meet someone new， but her name is gone before the handshake's over. Those are failures of your short-term，or “working，” memory——the place you file information for immediate， everyday retrieval. It isn't perfect. But researchers are increasingly convinced that the hormone estrogen could play a key role in maintaining and perhaps even improving memory. Last week a team of Yale scientists provided dramatic new evidence that bolsters the theory. Using MRIs——detailed snapshots of the brain——researchers found that women taking estrogen show significantly more activity in brain areas associated with memory than women on a placebo. “This is very exciting，” says Yale's Dr. Sally Shaywitz. “It means that the brain circuitry for memory had altered.”After menopause， when estrogen levels plummet， some women become forgetful. Past research has demonstrated that those who take estrogen do better on memory tests than their nonmedicated peers do. The hormone may even reduce the risk of Alzheimer's. The new study， published in last week's Journal of the American Medical Association，is the first to visually compare the neurocircuitry of memory both on and off estrogen. The drug made a big difference to participant Bernadette Settelmeyer：“All of a sudden I was remembering things.”The women (whose average age was 51) lay down in a brain-imaging machine where they were shown two types of information： nonsense words (“BAZ” or “DOB”) to test verbal memory and geometric patterns to assess visual memory. After a 20-second “storage” period， participants saw a mix of old and new and were asked if anything looked familiar. During each stage of the test——as the women encoded， stored and retrieved data——researchers took pictures of their brains. The 46 women underwent the test twice——once while taking a standard daily dose of estrogen and again while taking a placebo. Beyond the power of estrogen， the difference in MRIs suggests that the adult brain maintains “plasticity”——the ability to rewire itself——even as it ages.There is still plenty of research to be done. Scientists can't yet be sure estrogen is directly responsible for better memory performance. Despite the difference in brain activity on and off estrogen， participants' scores did not change. Researchers say that is probably because the tasks were so simple (the women got more than 90 percent correct overall)。

考研英语阅读理解模拟试题：医学（8）Should doctor-assisted suicide ever be a legal option？It involves the extreme measure of taking the life of a terminally ill patient when the patient is in extreme pain and the chances for recovery appear to be none.Those who argue against assisted suicide do so by considering the roles of the patient，the doctor，and nature in these situations.Should the patient take an active role in assisted suicide？When a patient is terminally ill and in great pain，those who oppose assisted suicide say that it should not be up to that patient to decide what his or her fate will be.There are greater powers at work that determine when a person dies，for example，nature.Neither science nor personal preference should take precedence over these larger forces.What role should the doctor have？Doctors，when taking the Hippocratic oath，swear to preserve life at all costs，and it is their ethical and legal duty to follow both the spirit and the letter of this oath.It is their responsibilities to heal the sick，and in the cases when healing is not possible，then the doctor is obliged to make the dying person comfortable.Doctors are trained never to hasten death.Those who oppose assisted suicide believe that doctors who do help terminally ill patients die are committing a crime，and they should be dealt with accordingly.Doctors are also，by virtue of their humanness，capable of making mistakes.Doctors could quite possibly say，for instance，that acancer patient was terminal，and then the illness could later turn out not to be so serious.There is always an element of doubt concerning the future outcome of human affairs.The third perspective to consider when thinking about assisted suicide is the role of nature.Life is precious.Many people believe that it is not up to human beings to decide when to end their own or another‘s life.Only nature determines when it is the right time for a person to die.To assist someone in suicide is not only to break criminal laws，but to break divine 1aws as well.These general concerns of those who oppose assisted suicide are valid in certain contexts of the assisted suicide question.For instance，patients cannot always be certain of their medical conditions.Pain clouds judgment，and so the patient should not be the sole arbiter of her or his own destiny.Patients do not usually choose the course of their medical treatment，so they shouldn‘t be held completely responsible for decisions related to it.Doctors are also fallible，and it is understandable that they would not want to make the final decision about when death should occur.Since doctors are trained to prolong life，they usually do not elect to take it by prescribing assisted suicide.I believe that blindly opposing assisted suicide does no one a service.If someone is dying of cancer and begging to be put out of his or her misery，and someone gives that person a deadly dose of morphine，that seems merciful rather than criminal.If we can agree to this，then I think we could also agree that having a doctor close by measuring the dosage and advising the family and friends is a reasonable request.Without the doctor‘s previous treatment，the person would have surely been dead already.Doctors have intervened for months or even years，so why not sanction this final，merciful intervention？Life is indeed precious，but an inevitable part of life is death，and it should be precious，too.If life has become an intolerable pain and intense suffering，then it seems that in order to preserve dignity and beauty，one should have the right to end her or his suffering quietly，surely，and with family and friends nearby.1. In this passage“doctor-assisted suicide”act ually refers to the practice that doctors____.[A]kill their patients by intentional inducement[B]unconsciously help their patients to commit suicide[c]propose euthanasia（安乐死）to the terminally ill patient[D]kill their patients with improper prescription2. People may object to doctor-assisted suicide on the ground that____.[A]patients should determine when they want to end their lives[B]doctors should be punished if they fail to save their patients[C]doctors may make mistakes in their diagnosis[D]doctors should wait until their patients‘death is certain3. Who has the power to decide when a person should die according to those who argue against assisted suicide？[A]The patient. [B]The doctor.[C]Nature. [D]None of the above.4. When speaking of the role patients play in assisted suicide，the author admits that____.[A]it is not up to them to make the choice[B]science is a better arbiter than their personal preference[C]personal preference should not be taken too seriously[D]they are unable to make the choice in some cases5. The author makes it clear that____.[A]he is opposed to doctor-assisted suicide[B]he is in favor of doctor-assisted suicide[C]he neither objects to nor favors doctor-assisted suicide[D]he thinks it better to leave the issue undiscussed at present1. [C] 第一段第二句实际上是doctor-assisted suicide的定义。
