填空题Clinical Trials 1 Many clinical trials are done to see if a new drug or device is safe and effective for people to use. Sometimes clinical trials are used to study different ways to use the standard treatments so they will be more effective, easier to use, and/or decrease side effects. Sometimes, studies are done to learn how to best use the treatment in a different population, such as children, in whom the treatment was not previously tested. 2 It is important to test drugs and medical products in the people they are meant to help. It is also important to conduct research in a variety of people because different people may respond differently to treatments. Some people participate in clinical trials because they have exhausted standard treatment options. Other people participate in trims because they want to contribute to the advancement of medical knowledge. 3 The FDA(食品及药物管理局)works to protect participants in clinical trials and to ensure that people have reliable information as they decide whether to join a clinical trial. Although efforts are made to control the risks to clinical trial participants, some risks may be unavoidable because of the uncertainty inherent (内在的) in medical research studies involving new medical treatments. 4 People should learn as much as possible about the clinical trials that interest them. They should also feel comfortable discussing their questions and concerns with members of the health care team. Prospective(预期的) participants should understand what happens during the trial, the type of health care they will receive, and any costs to them. Anyone considering a clinical trial should al so know that there are benefits and risks associated with participating. A. Why are clinical trials done? B. Where are clinical trials conducted? C. Who should consider clinical trials and why? D. What should people know before participating in a clinical trial? E. What are clinical trials? F. Are clinical trials safe?

填空题Many Benefit from Cancer Organization 1. Do you know a child who survived leukemia? Do you have a mother, sister or aunt whose breast cancer was found early thanks to a mammogram? Do you have a friend or coworker who quit smoking to reduce their risk of lung cancer? Each of these individuals benefited from the American Cancer Society's research program. 2. Each day scientists supported by the American Cancer Society work to find breakthroughs that will take us one step closer to a cure. The American Cancer Society has long recognized that research holds the ultimate answers to the prevention, diagnosis and treatment of cancer. 3. As the largest source of nonprofit cancer research funds in the United States, the American Cancer Society devotes over $100 million each year to research. Since 1946, they've invested more than $2.4 billion in research. The investment has paid rich dividends: In 1946, only one in four cancer patients was alive five years after diagnosis; today 60 percent live longer than five years. 4. Investigators and health professionals in universities, research institutes and hospitals throughout the country receive grants from the American Cancer Society. Of the more than 1,300 new applications received each year, only 11 percent can be funded. If the American Cancer Society had more money available for research funding, nearly 200 more applications considered outstanding could be funded each year. 5. You can help fund more of these applications by participating in the American Cancer Society Relay for Life, a team event to fight cancer. More funding means more cancer breakthroughs and more lives being saved. To learn more, call Donna Hood, chair with the Neosho Relay for Life of the American Cancer Society at 451-4880.

填空题 The Dangers of Secondhand Smoke Most people know that cigarette smoking is harmful to their health. Scientific research shows that it causes many kinds of diseases. In fact, many people who smoke get lung cancel. However, Edward Gilson has lung cancer, and he has never smoked cigarettes. He lives with his wife, Evelyn, who has smoked about a pack of cigarettes a day throughout their marriage. {{U}} {{U}} 1 {{/U}} {{/U}} No one knows for sure why Mr. Gilson has lung cancer. Nevertheless, doctors believe that secondhand smoke may cause lung cancer in people who do not smoke because nonsmokers often breathe in the smoke from other people's cigarettes. {{U}} {{U}} 2 {{/U}} {{/U}}The U. S. Environmental Protection Agency reports that about 53,000 people die in the United States each year as a result of exposure to secondhand smoke. The smoke that comes from a lit cigarette contains many different poisonous chemicals. In the past, scientists did not think that these chemicals could harm a nonsmoker's health. {{U}} {{U}} 3 {{/U}} {{/U}}They discovered that even nonsmokers had unhealthy amounts of these toxic (有毒的) chemicals in their bodies. As a matter of fact, almost all of U. S. breathe tobacco smoke at times, whether we realize it or not. For example, we cannot avoid secondhand smoke in restaurants, hotels and other public places. Even though many public places have nonsmoking areas, smoke flows in from the areas where smoking is permitted. It is even harder for children to avoid secondhand smoke. {{U}} {{U}} 4 {{/U}} {{/U}}Research shows that children who are exposed to secondhand smoke are sick more often than children who live in homes where no one smokes and that the children of smokers are more than twice as likely to develop lung cancer when they are adults as are children of nonsmokers. The risk is even higher for children who live in homes where both parents smoke. People are becoming very aware of the dangers of secondhand smoke. {{U}} {{U}} 5 {{/U}} {{/U}} A. Recently, though, scientists changed their opinion after they studied a large group of nonsmokers. B. The Gilsons have been married for 35 years. C. Which smoke is called secondhand smoke? D. However, secondhand smoke is dangerous to all people, old or young. E. As a result, they have passed laws which prohibit people from smoking in many public places. F. In the United States, nine million children under the age of five live in homes with at least one smoker.

填空题Caribbean Islands What would you see if you took a cruise to the Caribbean Islands? Palm trees and coconuts (椰子)? White beaches and clear, blue ocean? Colorful corals (珊瑚) and even more colorful fishes and birds? You bet. There are thousands of islands in the Caribbean Sea. They are famous for their warm, tropical climate and great natural beauty. The Caribbean Islands form a chain that separates the Caribbean Sea from the rest of the Atlantic Ocean. Some of the islands were formed by the eruption (爆发) of ancient volcanoes (火山). 11 The Caribbean Islands are known by several names. 12 The explorer Christopher Columbus called the islands the Indies in 1492 because he thought he was near the coast of India. Later, Spain and France called the islands the Antilles. There are four large islands in the Caribbean Sea. 13 These four islands are often called the Greater Antilles. Together, they account for about 90 percent of the land area of the Caribbean Islands. The rest of the Caribbean Islands are much smaller. Some of these islands are no more than tiny slivers (小片) of exposed coral. You can see why pirates (海盗) such as the famous Blackbeard sailed these waters. 14 The weather of the Caribbean Sea is almost always warm and sunny. Sandy beaches line the coasts of many islands. This is why millions of tourists visit the islands each year. 15 A. But life on the Caribbean Islands is not always paradise. B. The earliest name used by Europeans is the Indies, later changed to the West Indies. C. Others are low-lying coral islands that gradually rose from the ocean. D. They are Cuba, Puerto Rico, Jamaica, and Hispaniola. E. Many tourists arrive on cruise ships. F. There are countless small islands to bury treasure or hide on.

填空题Pregnant Women Warned About ACE Inhibitor Some of the most commonly used medicines for high blood pressure are drugs called ACE inhibitors. Doctors have given these drugs to patients for twenty-five years. A government study in the United States found that the use almost doubled between 1995 and 2000. Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy. The medicine can injure the baby. ACE inhibitors, though, have been considered safe when taken during the first three months. But a new study has found that women who take these drugs early in their pregnancy still increase the risk of birth disorders. The study shows that, compared to others, their babies were almost three times as likely to be born with major problems. These included problems with the formation of the brain and nervous system and holes in the heart. The researchers say they found no increased risk in women who took other blood pressure medicines during the first three months. Researchers at Vanderbilt University in Tennessee and Boston University did the study. The New England Journal of Medicine published the results. The researchers studied the records of almost thirty thousand births between 1985 and 2000. Two hundred nine babies were born to women who took ACE inhibitors during the first three months of their pregnancies. Eighteen of the babies, or almost nine percent, had major disorders. ACE inhibitors are often given to patients with diabetes. But diabetes during pregnancy can result in birth defects. So the study did not include any women known to be diabetic. ACE inhibitors suppress a protein called angiotensin-converting enzyme, or ACE. This enzyme produces a chemical in the body that makes blood passages narrow. The drugs increase the flow of blood so pressure is reduced. New drugs are tested on pregnant animals to see if they might cause birth defects in humans. But experts say these tests are not always dependable. The United States Food and Drug Administration helped pay for the study. The F. D. A. says women who might become pregnant should talk with their doctor about other ways to treat high blood pressure.

The closeness of Stanford to San Francisco, a city thirty-two miles to the north, gives the university a decidedly cosmopolitan (世界性的) flavor.2 The students are enrolled mainly from the western United States. But most of the fifty states send students to Stanford, and many foreign students study here, as well. And standards for admission remain high. Young men and women are selected to enter the university from the upper fifteen percent of their high school classes.3 Not only because of the high caliber (素质) of its students but also because of the desirable location and climate, Stanford has attracted to its faculty some of the world's most respected scholars. The university staff has included many Nobel Prize winners in various fields. Stanford's undergraduate school of engineering and its graduate schools of business, law, and medicine are especially well-regarded.4 What is student life like on "The Farm"? Culturally, the campus is a magnet for both students and citizens of nearby communities. Plays, concerts, and operas are performed in the university's several auditoriums and in its outdoor theater, where graduations are also held. Several film series are presented during the school year. Guest lecturers from public and academic life frequently appear on campus. For the sports-minded, the Stanford campus offers highly developed athletic facilities. Team sports, swimming, and track and field activity are all very much part of the Stanford picture. So are bicycling and jogging.5 In addition to financial support from alumni (校友), Stanford receives grants from the government and from private charities. In recent years, government grants have made possible advanced studies in the fields of history, psychology, education, and atomic energy. At present Stanford is carrying out an ambitious building program, financed in part by the Ford Foundation's 25 million grant. Recently added to the campus are a new physics building, new school of business, new graduate school of law, new student union, and undergraduate library.

填空题That can be a good thing, with the Web serving as a kind of buffer zone (缓冲地带) for uncomfortable interaction. It's easier to face rejection, there aren't lulls in conversation or geographic boundaries - and social networking is like a window into the lives of potential mates. Say two people meet on Facebook, though a mutual friend. Immediately, they know whether the other person is single - without having to ask. ______ It's all the details a person might encounter on a first or second date, without ever having to go on one. As David Yarus, a recent graduate of Babson College, outside Boston, puts it: "Facebook has taken the potentially awkward first stages of flirting and getting to know someone into the comfort of your own home. "A. It's easier to approach each other, to talk casually, to get to know one another and feel out romantic potential without ever having to truly put themselves out there.B. "And you don't even have to be on the computer to engage in it. "C. They can see where that person grew up, their political interests, whether they're "looking for a relationship" or only interested in" hooking up. "D. As the thinking went, if you had to go to the Web to find a mate, or break up with one, it must have meant you weren't capable of attracting anyone in the real world.E. Now a relationship may still begin by locking eyes across a crowded bar, but instead of asking for a phone number, the next step almost surely involves a Facebook friendship offer.F. David Hein zinger, a 24 - year - old new - media specialist in New York. recently asked a girl he met at a happy hour to dinner.

填空题Development in Newspaper Organization One of the most important developments in newspaper organization during the first part of the twentieth century 1 , which are known as wire services. Wire service companies employed reporters, who covered stories all over the world. Their news reports were sent to papers throughout the country by telegraph. The papers paid an annual fee for this service. Wire services continue 2 . Today the major wire services are the Associated Press (AP) and United Press International (UPI). You will frequently find AP or UPI at the beginning of a news story. Newspaper chains and mergers began to appear in the early 1900s. A chain consists of two or more newspapers 3 . A merger involves combining two or more papers into one. During the nineteenth century many cities had more than one competitive independent paper. Today in most cities there are only one or two newspapers, and 4 . Often newspapers in several cities belong to one chain. Papers have combined 5 . Chains and mergers have cut down production costs and brought the advantages of big-business methods to the newspaper industry.

填空题3. California University Cuts Protested Thousands of students, faculty members and employees at the 10 University of California campuses protested budget cuts, unpaid faculty furloughs (休假) and tuition increases on Thursday. Officials at the University of California, Berkeley, estimated that several thousand protesters were in Sproul Plaza chanting and waving signs. (46) Other campuses reported smaller turnouts (聚集的人群) at rallies (集会) and marches. "Everyone agrees there is a budget crisis and that the university must respond," said Joshua Clover, an associate professor of English at U. C. Davis who was a co - author of a petition (情愿书) calling for the faculty walkout on Thursday. Mr. Clover said (47) The online walkout petition was signed by 1,221 of the 19,000 faculty members statewide. A union representing more than 11,000 university professional and technical staff members supported the protest and called a one -day strike. (48) The university' s budget now stands at $ 2. 6 billion. Friction (摩擦) has developed between the administration and some faculty and staff members and students over how and where to cut. Among the more contentious (有异议的) items are a proposed 32 percent increase in student tuition by fall 2010, and decisions made by the university president, Mark Yudof, over how to handle mandatory (义务性质的) faculty furlough days, which will reduce pay by 4 to 10 percent. (49) "I chose Berkeley over all the other universities because it offered me a very good education at a price my family could afford," said Brandon Pham, 17, a freshman political science major who skipped the day' s classes in protest. Mr. Pham held a sign that read:" We make the university. They make the crisis. " Steve Montiel, a spokesman for the University of Califomia' s office of the president, said, (50) A. "We respect people expressing themselves, but we hope they realize that the true source of their frustration is in Sacramento at the state capital. "B. The Legislature approved a reduction of $ 637.1 million, about 20 percent of the university' s 2009 -2010 fiscal year (财政年度) financing, as part of the budget agreement reached in August.C. "The problem is that the administration' s handling of the budget cuts disproportionately (不成比例) harms those who can least afford it both among the workers and the students. "D. Average yearly tuition and fees for undergraduates this academic year are $ 8,720.E. Most academic departments on campus reported that some classes had been canceled because faculty members and students walked out.F. Still, many students at Berkeley did not participate in the protest and walked about campus as they would on any other Thursday.

填空题 Understanding Autism 1. Autism (孤独症) is a life-long developmental disability that prevents individuals from properly understanding what they see, hear, and otherwise sense. This results in severe problems of social relationships, communication, and behavior. Individuals with autism have to painstakingly (费力地) learn normal patterns of speech and communication, and appropriate ways to relate to people, objects, and events, in a similar manner to those who have had a stroke. 2. The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information coming in from the senses. There may be some imbalance of certain chemicals in the brain. Genetic (遗传的) factors may sometimes be involved. Autism may indeed result from a combination of several "causes". 3. Most people with mental retardation (智力迟钝的) show relatively even skill development. Individuals with autism, however, typically show uneven skill development, with deficits (欠缺) in certain areas—most frequently in their ability to communicate and relate to others—and distinct skills in other areas. It is important to distinguish autism from mental retardation or other disorders, since diagnostic (诊断的) confusion may lead to inappropriate and ineffective treatment techniques. 4. In general, individuals with autism perform best at jobs which are structured and involve a degree of repetition. Some people who have autism are working as artists, piano tuners, painters, farm workers, office workers, computer operators, dishwashers, assembly line workers, or employees of sheltered workshops or other sheltered work settings.

填空题Exercising Your Memory 1 Aging does not mean a dramatic decline in memory power, unless you help it happen by letting your mind go. 2 That"s not to say that memory doesn"t change throughout life. Researchers divide memory into categories based on the length of time when memories are stored. One system divides it up as short-term (less than one minute; remembering a telephone number while you dial, for instance), long-term (over a period of years) and very long-term memory (over a lifetime). 3 Short-term memory isn"t mastered until about age 7, but after that you never lose it. Long-term memory, however, involves more effort and skill and changes more through life. It"s not until the early teens (十几见闻) that most people develop a mature long-term memory. 4 First, we must get information into our heads through learning. Learning strategies can get rusty (生锈) without constant use. High school and college students, who are forced to repeatedly exercise their long-term memory abilities (at least long-term enough to get them through a final exam ), usually do well on memory tests. The longer you stay in school, the more chance you get to polish your learning skills. It"s no wonder that more highly educated people have more effective memory skills throughout life. 5 Although older people in general learn somewhat more slowly than they did when younger, a dramatic difference exists between those who stay intellectually active—reading, discussing, taking classes, thinking—and those who do not. Giving the brain daily workout (锻炼) is just as important as exercising your muscles. Brainwork keeps your learning strategies in shape, and this helps your memory to function at full capacity. 6 The next part of a healthy long-term memory is retention (记忆力), the ability to store what you have learned. Memory researchers still do not know whether memories are lost—whether they still exist in the brain but our mental searching cannot turn them up, or have disappeared entirely as our brain ages. 7 The third necessity for memory is recall, the ability to bring to mind the memories we have stored. Again, while aging has widely different effects on the recall abilities of different people, research indicates that the older we get, the longer it takes to recall facts. But slower recall is still recall. In fact, aging does not seem to have any effect on forgetting at all, which takes place at the same rate in younger and older people.

填空题Sleep Well to Be Well Do you often feel tired in the morning even though you"ve been in bed for seven or eight hours the night before.* Like many people, you are not sleeping as much as you think you are. In other words, your sleep efficiency is not that good. Sleep experts define "sleep efficiency" as the percentage of time lying down that you are actually sleeping. According to the Explanatory Journal , the science of sleep efficiency is still young. There is no specific number for efficiency that"s been proven as linked to poor health. However, according to a New York Times report about sleep quality, some experts estimate a rough ballpark (范围) of 85 percent or above as a decent place to be. 3 Short wavelength blue light, emitted (放出) by the sun and by the screens of computers, iPads and smartphones, stops production of the sleep-inducing hormone melatonin (褪黑素) and makes you feel more active. Blue light tells your brain it"s daytime. Experts suggest turning off your computers and smartphones one hour or at least 30 minutes before bed. Go to bed and wake up at the same time, or relatively the same time, every day. Avoid binge sleeping (狂睡) on the weekend. Consistency is the key to a good night"s sleep, especially when it comes to waking up. When you have a consistent wake-up time, your brain accustoms to this and moves through the sleep cycle in preparation for you to feel rested and active at your wake-up time. One of the biggest peaks in melatonin production happens during the 1 to 3 pm time frame, which explains why most people feel sleepy in the afternoon. If you aren"t getting enough sleep at night, you"re likely going to feel an overwhelming desire to sleep in the afternoon. When this happens, you"re better off taking a short nap than resorting to caffeine or strong tea to keep you awake. A short nap will give you the rest you need to get through the rest of the afternoon, and you"ll sleep much better in the evening than if you drink caffeine or take a long afternoon nap.

填空题The Invader of AIDS The invader is small, even in the microscopic world of bacteria and viruses. It is alive only in the strictest sense of the world. It had no intelligence, no means of mobility, and no methods of defense in the outside world. It is fragile, easily killed by common household bleach (漂白剂) and even short periods outside the body. 1 It is the AIDS virus, and it is a killer. AIDS is a disease, caused by a virus that breaks down part of the body"s immune system, leaving a person defenseless against a variety of unusual life-threatening illnesses. 2 The body"s immune system normally provides us the weapons we need to win constant battles with invading viruses, bacteria and other invading organisms. His defense system is powerful but not perfect. 3 We do not even know that anything is happening. But the AIDS virus acts differently from other invaders. It attacks the very cells that normally protect us. 4 It turns our own white blood cells into mini-factories or making more viruses. Each time a cell is taken over, it fills up with thousands of new viruses, dies and releases those viruses which attack more white blood cells. After enough attacks, our defense system is weakened and certain infections and conditions that we normally fight off with no problem take advantage of his weakness. 5 The person dies. There is no cure for AIDS, so learning about the disease and how to avoid it are our only weapons. A. Yet it may be the most dangerous enemy in human history. B. Whatever condition develops because of AIDS, the outcome is always the same. C. It gets inside these cells. D. Each of the letters in AIDS stands for a word: Acquired Immune Deficiency Syndrome. E. The patients who suffer from AIDS have characteristic features. F. Most attacks are detected and beaten off with ease.

填空题 {{B}}Bomb Explosions in Thailand{{/B}} The new year celebration in Thailand was shattered by violence, when nine bombs exploded across Bangkok around midnight. Three Thai citizens were killed and more than 30 injured. Among the injured, six were foreigners. No Chinese casualties were reposed, the Chinese Embassy in Bangkok, the capital, said on Monday. {{U}} {{U}} 1 {{/U}} {{/U}}But other embassies have advised their citizens to avoid traveling to Bangkok. "There is a possibility of further attacks in coming days," said a travel advisory (公告) from Australia. "Australians are urged to avoid unnecessary travel in Bangkok." No terrorist group claimed responsibility for the bombings by Tuesday. {{U}} {{U}} 2 {{/U}} {{/U}}Bombings and shootings occur almost daily in Thailand's three southernmost provinces. Yala, Naarathiwat and Pattani have a dominant Muslim population and have long complained of neglect (忽视) and discrimination (歧视) in the largely Buddhist (佛教徒的) nation.

填空题 The First Four Minutes When do people decide whether or not they want to become friends? During their first four minutes together, according to a book by Dr. Leonard Zunin. In his book, Contact. The first four minutes, he offers this advice to anyone interested in starting new friendships: {{U}} {{U}} 1 {{/U}} {{/U}}A lot of people's whole lives would change if they did just that. You may have noticed that average person does not give his undivided attention to someone he as just met. {{U}} {{U}} 2 {{/U}} {{/U}}If anyone has ever done this to you, you probably did not like him very much. When we are introduced to new people, the author suggests, we should try to appear friendly and self-confident. In general, he says, "People like people who like themselves." On the other hand, we should not make the other person think we are too sure of ourselves. It is important to appear interested and sympathetic, realizing that the other person has his won needs, fears, and hopes. Hearing such advice, one might say, "But I'm not a friendly, self-confident person. That's not my nature. It would be dishonest for me to act that way." {{U}} {{U}} 3 {{/U}} {{/U}}We can become accustomed to any changes we choose to make in our personality. "It is like getting used to a new car. It may be unfamiliar at first, but it goes much better than the old one." But isn't it dishonest to give the appearance of friendly self-confidence when we don't actually feel that way? Perhaps, but according to Dr. Zunin, "total honest" is not always good for social relationships, especially during the first few minutes of contact. There is a time for everything, and a certain amount of play-acting may be best for the first few minutes of contact with a stranger. That is not the time to complain about one's health or to mention faults one finds in other people. It is not the time to tell the whole truth about one's opinions and impressions. {{U}} {{U}} 4 {{/U}} {{/U}}For a husband and wife or a parent and child, problems often arise during their first four minutes together after they have been apart. Dr. Zunin suggests that these first few minutes together be treated with care. If there are unpleasant matters to be discussed, they should be dealt with later. The author says that interpersonal relations should be taught as a required course in every school, along with reading, writing, and mathematics. {{U}} {{U}} 5 {{/U}} {{/U}}That is at least as important as how much we know. A. In reply, Dr. Zunin would claim that a little practice can help us feel comfortable about changing our social habits. B. Much of what has been said about strangers also applies to relationships with family members and friends. C. In his opinion, success in life depends mainly on how we get along with other people. D. Every time you meet someone in a social situation, give him your undivided attention for four minutes. E. He keeps looking over the other person's shoulder, as if hoping to find someone more interesting in another part of the room. F. He is eager to make friends with everyone.

填空题"I smoke for my health," I declared in a newspaper article published in 1979. (46) . I reasoned that smoking made me cough and thus prevented pneumonia (肺炎); smoking made my heart go faster and eliminated the need for special exercise; smoking restrained my appetite and kept me trim. And then, at 51, I had a heart attack. I knew the risk factors for early heart attacks include hypertension, diabetes(糖尿病), and a family history of heart disease, high blood-cholesterol (胆固醇)levels and smoking. (47) . Strange how the evidence that linked smoking to heart disease appeared unclear to me, and how the same data now appear overwhelmingly convincing. Why stop now? Smokers who stop after their first heart attack have an 80-percent chance of living ten more years-- (48) . As a smoker, I always resented the fact that we smokers received only scorn from non-smokers. How could non-smokers know that smoking was had for the health if there were no smokers to prove it? Being a member of the experimental group, rather than the control group, deserves a certain measure of social appreciation. I've done my time. I' m now ready to be a control. I no longer smoke for my health. My health can' t stand the help. Will I miss the late - night trips to find a store that's still open and selling cigarettes? Will I miss searching through ashtrays(烟灰缸)to find the longest butt(烟蒂) that is still smokable? Only time will tell. Not smoking may give me the time to find out. (49) Sure. Here is all you have to do. First, experience a severe crushing pain under your breastbone as you finish a cigarette. Next, have yourself admitted to a coronary-care(心脏康复)unit and be stripped of your clothing and belongings. Finally, remain in the unit at absolute bed rest for four days while smoking is forbidden. This broke my habit (50) A. Was it easy to stop?B. if they don't, a 60 percent chance.C. See if it works for you.D. All the smokers find it's hard to stop.E. Since I am a doctor, this advice attracted amused attention.F. The first four were in my favour, but I chose to smok

填空题Organ Donation and Transplantation 1 Organ donation and transplantation refers to the process by which organs or tissues from one person are put into another person's body. 2 The number of people needing a transplant continues to rise faster than the number of donors. About 3,700 transplant candidates are added to the national waiting list each month. Each day, about 77 people receive organ transplants. However, about 18 people die each day waiting for transplants that can't take place because of the shortage of donated organs. 3 There are no age limits on who can be an organ donor. Newborns as well as senior citizens have been organ donors. If you are younger than 18, you must have a parent's or guardian's consent. If you are 18 years or older, you can show you want to be an organ and tissue donor by signing a donor card. 4 Many people think that if they agree to donate their organs, the doctor or the emergency room staff won't work as hard to save their life.
