职称英语考试《卫生类》模拟试题及答案0511-151、SemcoAt 21, Ricardo Semler became boss of his father-s business in Brazil, Semco, which sold parts for ships. 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. ____ 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. He doesn't even pretend to be busy. But when a Semco pump an the other side of the world fails and millions of gallons of oil are about to spill into the sea, Rubin springs into action.He knows everything there is to know about our pumps and how to fix them. That's when he earns his salary. No one cares if he doesn't look busy the rest of the time."Semco has flexible working hours, the employees decide when they need to arrive at work, The employees also evaluate their bosses twice a year. 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? The answer is in the numbers. In the last six years, Semco's revenues have gone from $ 35 million to $ 212 million. The company has grown from eight hundred employees to 3,000, Why?Semler says it's because of "peer pressure". Peer pressuremakes everyone work hard for everyone else. doing his job well, the other workers will not allow the situation to continue. In other words, Ricardo Semler treats his workers like adults and expects them to act like adults, And they do.【单选题】A.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.B.Most managers spend their time making it difficult for workers to work.C.This saved money and brought more equality to the company.D.And the workers are free to decorate their workspace as they want.E.He knows everything there is to know about our pumps and how to fix them.F.If someone isn't doing his job well, the other workers will not allow the situation to continue.正确答案:D答案解析:本题难度也较大，需要认真阅读文章，可用排除法和代入法。

2、Musical Training Can Improve Communication Skills American scientists say musical training seems to improve communication skills and language retardation. They found that developing musical skills involves the same process in the brain as learning how to speak. The scientists believe that could help children with learning disabilities.Nina Kraus is a neurobiologist at Northwestern University in Illinois. She says musical training involves putting together different kinds of information, such as hearing music, looking at musical notes, touching an instrument and watching other musicians. This process is not much different from learning how to speak. Both involve different senses.She further explains musical training and learning to speak each make us think about what we are doing. She says speech and music pass through a structure of the nervous system called the brain stem. The brain stem controls our ability to hear. Until recently, experts have thought the brain stem could not be developed or changed. But Professor Kranss and her team found that musical training can improve a person's brain stem activity.The study involved individuals with different levels of musical ability. They were asked to wear an electrical device that measures brain activity. The individuals wore the electrode while they watched a video of someone speaking and a person playing a musical instrument ---- the cello.Professor Krauss says cellos have sound qualities similar to some of the sounds that are important with speech. The study found that the more years of training people had, the more sensitive they were to the sound and rhythm of the music. Those who were involved in musical activities were the same people in whom the improvement of sensory events was the strongest. ____ She says using music to improve listening skills could mean they hear sentences and understand facial expressions better.【单选题】A.Both involve different senses.B.Nina Kraus is a neurobiologist at Northwestern University in Illinois.C.Some disabled children attended the musical training Class.D.It shows the importance of musical training to children with learning disabilities.E.Professor Krauss says cellos have sound qualities similar to some of the sounds that are important with speech.F.The brain stem controls our ability to hear.正确答案:D答案解析:最后一段介绍音乐训练的方法和结果，以及对学习的关联和影响。

2、Nurse! I Want My MummyWhen a child is ill in hospital, a parent's first reaction is to be with them.Most hospitals now allow parents to sleep overnight with their child, providing a bed or sofa on the ward.But until the 1970s this practice was not only frowned upon (不赞同) —it was actively discouraged. Staff worried that the children would be upset when their parents left, and so there was a blanket (通用的) ban.A concerned nurse, Pamela Hawthorn, disagreed and her study "Nurse, I want my mummy!" published in 1974, changed the face "paediatric (儿科的) nursing.Martin Johnson, a professor of nursing at the University ofSalford, said that the work of nurses like Pamela had changed the face of patient care."Pamela's study was done against the background of a lively debate in paediatrics and psychology as to the degree women should spend with children in the outside world and the degree to which they should be allowed to visit children in hospital." "The idea was that if mum came to visita small child in hospital the child would be upset and inconsolable (无法安慰的) for hours. ""Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. " "Of course we know now that they had almost given up hope ____ mum was ever coming back.""To avoid a little bit of pain they said that no one should visit." "But children were alone and depressed, so Hawthorn said parents should be allowed to visit."Dr. Peter Carter, chief executive and general secretary of the Royal College of Nursing, said her work had been seminal (开创性的)."Her research put an end to the days when parents handedtheir children over to strangers at the door of the hospital ward.""As a result of her work, parents are now recognized as partners in care and are afforded the opportunity to stay with their children while they are in hospital, which has dramatically improved both parents' and children's experience of care." 【单选题】A.unlessB.thatC.becauseD.whether正确答案:B答案解析:本题有一定难度，考查同位语从句引导词that的用法，此处只能用that引导同位语从句，that表示对先行词hope 进行解释说明，答案是B。

xx年职称英语资格考试卫生类A级模拟试题及答案It's a modem problem: you're too busy to be disturbed by incessant (连续不断的) phone calls so you turn your cell phone off.But if you don't remember to turn it back on when you're less busy. You could miss some important calls if only the phone knew when it was wise to interrupt you, you wouldn't have to turn it off at all. Instead, it could let calls through when you are not too busy.A bunch of behavior sensors (传感器) and a clever piece of software could do just that, by analyzing your behavior to determine if it's a good time to interrupt you. If built into a phone, the system may decide you're too busy and ask the caller to leave a message or ring back later.James Fogarty and Scott Hudson at Camegie Mellon University in Pennsylvania based their system oil tiny microphones, cameras and touch sensors that reveal body language and activity. First they had to study different behaviors to find out which ones strongly predict whether your mind is interrupted.The potential "busyness" signals they focused on included whether the office doors were left open or closed, the time of day, if other people were with the person in question, how close they were to each other, and whether or not the puter was in use.The sensors monitored these and many other factors while four subjects were at work. At random intervals, the subjects rated how interruptible they were on a scale ranging from "highly interruptible" to "highly not-interruptible". Their ratings were then correlated with the various behaviors . "It is a shotgun (随意的) approach: we used all the indicators we could think of and then let statistics find out which were important, " says Hudson.The model showed that using the keyboard, and talking on a landline or to someone else in the office correlated most strongly with how interruptible the subjects judged themselves to be. Interestingly, the puter was actually better than people at predicting when someone was too busy to be interrupted.The puter got it right 82 per cent of the time, humans 77 per cent. Fogarty speculates that this might be because people doing the interrupting are inevitably biased towards delivering their message, whereas puters don't care.The first application for Hudson and Fogarty's systemis likely to be in an instant messaging system, followed by office phones and cellphones. "There is no technological roadblock (障碍) to it being deployed in a couple of years, " says Hudson.问题A big problem facing people today is that.A.they must tolerate phone disturbances or miss important calls.B.they must turn off their phones to keep their homes quiet.C.they have to switch from a desktop phone to a cell phone.D.they are too busy to make phone calls.37、 The behavior sensor and software system built in a phone.A.could help store messagesB.could send messages instantlyC.could tell when it is wise to interrupt youD.could identify important phone calls38、 Scientists at Carnegie Menon University tried to find out.A.why office doors were often left openB.when it was a good time to turn off the puterC.what questions office workers were bothered withD.which behaviors could tell whether a person was busy39、 During the experiment, the subjects were asked.A.to control the sensors and the cameraB.to rate the degrees to which they could beinterruptedC.to pare their behaviors with others'D.to analyze all the indicators of interruption40、 The puter performed better than people in the study because.A.the puter worked harderB.the puter was not busyC.people tended to be biasedD.people were not good at statistics41、根据以下材料，答复41-55题If pollution continues to increase at the present rate, formation of aerosols (浮质) in the atmosphere will cause the onset (开始) of an ice age in about fifty years' time. This conclusion, reached by Dr. S.I. Rasool and Dr. S.H. Schneider of the United States Goddard Space Flight Centre, answers the apparently conflicting questions of whether an increase in the carbon dioxide (二氧化碳) content of the atmosphere will cause the Earth to warm up or increasing the aerosol content will cause it to cool down. The Americans have shown conclusively that the aerosol question is dominant.Two specters haunting conservationists have been the prospect that environmental pollution might lead to thepla's being unbearably hot or cold.One of these ghosts has now been laid.Because it seems that even an increase in the amount of carbon dioxide in the atmosphere to eight times its present value will produce an increase in temperatureof only 2 ℃, which would take place over several thousand years. But the other problem now looms larger than ever.。

4、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 age to 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 yetknow 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 is the same remains unknown.The finding could prove to be useful to ____.【单选题】A.the analysis of cardiac cellsB.the prevention of chronic diseasesC.the treatment of heart diseaseD.the study of longstanding mysteries正确答案:C答案解析:根据是第二段中：The finding，…，could open a newpath for the treatment of heart diseases这一研究成果将为心脏病的医治开拓新的途径。
