职称英语考试《卫生类》每日一练精选及答案0530-791、Surprised by a MiracleI had been working in the trauma unit at a local hospital for about a year. You get used to families thinking that a "coma" patient is moving their hand or doing something that they were asked to do. "Following commands" is what we call it. Often it's "wishful thinking" on the Families' part. Nurses can easily become callous to it.On this particular night during visiting hours, my patient's wife came in. I had taken care of him for several nights. I was very familiar with his care and what he was able to do. Actually, he didn't do anything. He barely moved at all, even when something would obviously hurt him, such as suctioning.His wife was very short, about 5 feet tall. She had to stand on a stool to lean over him, so that she could see his face and talk to him. She climbed up on the stool. I spoke to her for a few minutes, and then stepped out to tend to my other patient. A few minutes later, she came running out of the room. In anexcited voice, she said, "Donna, he's moving his hand!"I immediately thought that it was probably her imagination, and that he had not actually done it on purpose. He had been there about a month at the time and had never made any movements on purpose. I asked her what had happened and she said, "I asked him to squeeze my hand and he did!"This led me to another train of questioning. "But, did he let go when you asked him to?" She said yes, that he had done exactly what she asked.I went into the room with her, not really believing that I would see anything different than I had always seen. But I decided that it would be better to pacify her than to make her think I didn't believe her or that she was somehow mistaken.She asked him to squeeze her hand, which he did. I said, "Well, ask him to let go. " He continued to squeeze for a moment, so that when he finally did let go, I really still didn't believe that he had done it on purpose. So, I said, "Ask him to hold up one finger. " He did as asked.Well, hmm, this was starting to get my attention. I looked at him, his face still somewhat swollen and his eyes still closed. "Stick out your tongue!" I said. He did it. I almost fell on the floor. It was the first time I had ever seen anyone "wake up. "How did the author feel upon first hearing what the excited wife said?【单选题】A.She was amused.B.She was doubtful.C.She was scared.D.She was shocked.正确答案:B答案解析:短文的第三段的头一句话表明，作者开始基本上不相信病人家属所说的话。

职称英语考试《卫生类》每日一练精选及答案0530-1061、Human Heart Can Make New CellsSolving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac cells throughout the life span, although the rate of new cell production slows with age.The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say."We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with or if they could be renewed," he said.The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover rate decreases with ageto only 0. 45 percent by age 75,"If we can understand how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals that promote this process to stimulate regeneration after for example, a heart attack, "Frisen said. That could lead to treatment that helps restore damaged hearts.A lot of people suffer from chronic heart failure," noted co-author Dr. Ratan Bhardwaj.Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.With this finding, scientists are "opening the door to potential therapies to having ourselves heal ourselves," Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing. "But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts isthe same remains unknown.In people in their mid-70s, only 0.45 percent of cardiomyocytes ____.【单选题】A.are still functionalB.are reduced each yearC.are replaced each yearD.are damaged each year正确答案:C答案解析:第四段说，一个人20岁时，其每年被更替的心肌细胞为1%，随着年龄的增长，该更替率( turnover rate)不断下降，等到75岁时，只有0. 45%。

职称英语考试《卫生类》每日一练精选及答案0530-671、BaseballThere are people in Italy who can't stand soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn or even frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it's a game better suited to the 19th century, slow, quiet and gentlemanly. These are the same people you may be one of them who love football because there's the sport that glorifies "the hit".By contrast, baseball seems abstract, cool, silent and still. On TV the game is fractured into a dozen perspectives, replays and close ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the gameaffords so much space and time for involvement. The TV won't do it for you.Take, for example, the third baseman. You sit behind the third base dugout and you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms or bring the glove to a point in front of him, takes a step right or left, backward or forward, perhaps he glances across the field to check his first baseman's position. Suppose the pitch is a ball. "Nothing happened," you say. "I could have had my eyes closed".The skeptic and the innocent must play the game. And this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood if football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking of notes, chores and responses.The author admits that ____.【单选题】A.baseball is too peaceful for the youngB.baseball may seem boring when watched on TVC.football is more attracting than baseballD.baseball is more interesting than football正确答案:B答案解析:第三段指出，在电视上垒球运动被切换成不同角度的画面，而且不断地使用重放、特写等电视制作技术，这破坏了该运动的整体运动感，使观众无法将自己投入(project)到运动中去，以体会到这种寓动于静的运动之美。

职称英语考试《卫生类》每日一练精选及答案0530-1441、The motorcarSome pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly. change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion. One proposed solution to this problem is the automated highway system.When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail,which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car＇s movements.The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.In an automated highway system, all the driver needs to do is ____.【单选题】A.keep in the right laneB.wait to arrive at his destinationC.keep in constant touch with the computer centerrm the system of his destination by phone正确答案:D答案解析:文章的最后一段the driver will use a telephone to dial instructions about his destination into system说明本题的答案为D，即在计算机监控系统下，司机所做的不过是通过电话告诉系统自己的目的地而已。

职称英语考试《卫生类》每日一练精选及答案0530-1391、Parkinson＇s Disease1 Parkinson＇s disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine. Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly and do what you want them to do. When you have Parkinson＇s, these nerve cells break down. Then you no longer have enough dopamine, and you have trouble moving the way you want to.2 No one knows for sure what makes these nerve cells break down. But scientists are doing a lot of research to look for the answer. They are studying many possible causes, including aging and poisons in the environment. Abnormal genes seem to lead to Parkinson＇s disease in some people. But so far, there is not enough proof to show that it is always inherited.3 Tremor may be the first symptom you notice. It is one of the most common signs of the disease, although not everyone hasit. More importantly, not everyone with a tremor has Parkinson＇s disease. Tremor often starts in just one arm or leg or only on one side of the body. It may be worse when you are awake but not moving the affected arm or leg. It may get better when you move the limb or you are asleep. In time, Parkinson＇s affects muscles all through your body, so it can lead to problems like trouble swallowing or constipation. In the later stages of the disease, a person with Parkinson＇s may have a fixed or blank expression, trouble speaking, and other problems. Some people also have a decrease in mental skills (dementia).4 At this time, there is no cure for Parkinson＇s disease. But there are several types of medicines that can control the symptoms and make the disease easier to live with. You ＇may not even need treatment if your symptoms are mild. Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctor will adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.A lot of research is being done to find out ____.【单选题】A.if there isn＇t enough dopamine your bodyB.what affects muscles all through your bodyC.which cannot be cured yetD.if you have a fixed or blank expressionE.which may be the first symptom you noticeF.what causes Parkinson＇s disease正确答案:F答案解析:人们正在进行大量的研究来发现导致帕金森综合征的原因。

2、Intellectual DisabilityPeople with intellectual disability form one of the largest single disability groups in a community. Intellectual disability refers to a general slowness to learn and function within society, and the identification of intellectual disability is usually based on an assessment of a person's performance in a variety of tests. An individual's level of performance, as assessed, can change with time and circumstances. With skilled training and opportunity for development, people with intellectual disability have much greater potential for acquiring skills and for participation in community life than previously had been thought possible.In many western societies, five categories of intellectual disability have traditionally been used in order to indicate the perceived degree of difficulty an individual has with learning. All five may occur in either children, adolescent or adult, and show as mild, moderate, severe, profound or multipleintellectual disability.For the majority of intellectual disabilities, there is no identifiable cause but there are some causes that are well documented. They include: brain damage at birth due to lack of oxygen—prolonged labor during childbirth; brain damage before birth due to factors such as rubella (风疹), drug or diet-related problems; damage after birth due to illnesses such as encephalitis(脑膜炎) or accident; hereditary defects in the genes; abnormal chromosome count resulting in, for example, Down Syndrome(唐氏综合症).Like everyone else, people with an intellectual disability need a rewarding job, a satisfying place to live and a good social life. But they may need extra support to achieve these things. Good support services are based on the principle of normalization—which means enabling people to be part of the community like everyone else,With the introduction of the intellectually disabled into communities, there is a need to promote awareness of communication. Although many people may have little experience in talking with an intellectually disabled person, there are common guidelines that can simplify the interaction. Firstly, it is useful to remember that people with disabilitieshave feelings. Speaking in the same friendly manner as you would to anyone else is also recommended. Being prepared to wait a little longer for replies during a conversation with an intellectually disabled person would undoubtedly benefit the exchange.Paragraph 3____.【单选题】A.What do people with an intellectual disability needB.What is intellectual disabilityC.How do people with an intellectual disability talkD.What are the forms of intellectual disabilityE.What causes intellectual disabilityF.How do you talk to a person with an intellectual disability正确答案:E答案解析:第三段主题句为第一句，其意思是：尽管大多数智力障碍者的患病原因还未被查明，但有些因素确实能导致智力障碍。

职称英语考试《卫生类》每日一练精选及答案0530-681、Hurricanes1 Did you know that before 1950, hurricanes had no names? They were simply given numbers. The first names ware simply Alpha, Bravo, Charlie, etc. But in 1953, female names were given because of the unpredictability factor of the storms. In 1979, realizing the sexist nature of such named, the lists were expanded to include both men and women.2 Hurricanes and typhoons are the same things. If they form in the Atlantic, we call these strong storms hurricanes, from the West Indian word hurricane, meaning "big wind. " And if they are pacific storms, they are called typhoons from the Chinese taifun, meaning "great wind. " To be classified as a hurricane, the storm must have maximum winds of at least 75 mph. These storms are big, many hundreds of miles in diameter.3 Hurricanes get their power from water vapor as it gives out its stored-up energy. All water vapor gives out heat as it condenses from a gaseous state to a liquid state over fixed points on theequator. To make a hurricane, you must have extremely wet, warm air, the kind of air that can only be found in tropical regions.4 Scientists have determined that the heat given out in the process of water condensation can be as high as 95 billion kilowatts per hours. In just one day alone, the storm can produce more energy than many industrialized nations need in an entire year! The problem is that we don't know how to make such great energy work for us.5 Predicting the path of a hurricane is one of the most difficult tasks for forecasters, it moves at a typical speed of 15 mph. But not always. Some storms may race along at twice this speed, then suddenly stop and remain in the same location in the ocean for several days. It can be maddening if you live in a coastal area that may be hit.6 The biggest advance in early detection is continuous watch from weather satellites. With these, we can see the storms form and track them fully, from birth to death. While they can still kill people and destroy property, hurricanes will never surprise any nation again.From the passage we may rightly deduce that energy specialists may be interested in the hurricane's ____.【单选题】A.timely discovery of hurricaneB.convenienceC.sex equalityD.its connection with humansE.huge powerF.uncertainty正确答案:E答案解析:第四段谈到，飓风在水凝结的过程中，每小时能产生950亿千瓦的能量关键是我们不知道如何才能利用飓风产生的巨大的能量。

Semler Junior worked like a madman, from 7:30 am. , until midnight every day. One afternoon, while touring a factory in New York, he collapsed. The doctor who treated him said, "There's nothing wrong with you. But if you continue like this, you'll find a new home in our hospital." Semler got the message. He changed the way he worked. In fact, he changed the way his employees worked too. He let his workers take more responsibility so that they would be the ones worrying when things went wrong. He allowed them to set their own salaries, and he cut all the jobs he thought were unnecessary, like receptionists and secretaries. This saved money and brought more equality to the company. "Everyone at Semco, even top managers, meets guests in reception, does the photocopying, sends faxes, types letters and dials the phone."He completely reorganized the office, instead of walls, they have plants at Semco, so bosses can't shut themselves away from everyone else. And the workers are free to decorate their workspace as they want. As for uniforms, some people wear suits and others wear T - shirts.Semler says, "We have a sales manager named Rubin Agater who sits there reading the newspaper hour after hour.

Also, Semco lets its workers use the company's machines for their own projects, and makes them take holidays for at least thirty days a year.It sounds perfect, but does it work?

职称英语考试《卫生类》每日一练精选及答案0530-571、Smallpox virusIt's now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. And the last “official” stocks of live virus bred mistrust of the US and Russia, for no obvious gain. Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So one again there's a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US and Russia? Simple.Keep the virus under international auspices in a well-guarded UN laboratory that's open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn't mean the idea is wrong. If the virus ____ useful, then let's make it the servant of all humanity—not just a part of it.【单选题】A.will?beB.would?beC.isD.are正确答案:C答案解析:本句是个条件句。
从句中动词一般用现在时表示“未来”。
这就排除了will?be和would?be。
virus是单数，因此D也不正确。
故C为正确答案。
2、Cancer1. Cancer is a group of many related diseases that begin in cells, the body's basic building blocks. The body is made up of many types of cells. Normally, cells grow and divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should. The extra cells form a mass of tissue called a growth or tumor(肿瘤). Benign(良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal and divide without control or order.2. Scientists have learned that cancer is caused by changes in genes that normally control the growth and death of cells. Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet(紫外线的) radiation from the sun, or exposure to carcinogens (致症物) in the workplace or in the environment. Some gene alterations are inherited.3. Cancer treatment can include surgery, radiation therapy, chemotherapy(化疗), hormone therapy, and biological therapy. The doctor may use one method or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient's age and general health and other factors. Because treatment for cancer can also damage healthy cells and tissues, it often causes side effects. Patients and doctors generally discuss the treatment options, weighting the likely benefits of killing cancer cells and the risks of possible side effects.4. Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease and the patient's tolerance for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over - the - counter drugs recommended by the doctor.Cancer occurs when cells in the body divide without ______. 【单选题】A.side effectsB.prescription medicinesC.control or orderD.tolerance for painE.various factorsF.different genes正确答案:C答案解析:本题有一定难度，需要认真寻找答案依据。
答案依据在文章第一段最后一句：Cells in malignant tumors are abnormal and divide without control or order.谈到恶性肿瘤的细胞是变异的，毫无秩序或无法控制地分裂，回来看选项，C项符合原文句意，是答案。
