2019职称英语考试卫生B级考试题库阅读判断The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,and to move from place to place. In fact,the human body does its work so well that most people don't think about it very much —until they get sick.The germs （致病菌） that make people sick are eyerywhere. You can't see them ,but they're there. They're sitting on your desk. They're hiding on your computers keyboard. They're even in the air that you are breathing. There are two types of germs： viruses and bacteria （细菌）。

Viruses are germs that can only live inside animals or plants. Viruses cause illnesses such as flu and measles （麻疹） . Bacteria are tiny creatures. Some bacteria are good. They can help your stomach break down food. Other bacteria aren't so good. They can make you sick.Bacteria can cause sore throats （喉痛） and ear infections.How can you stop these tiny invaders from making you sick? Your skin is the first defense against germs. You can prevent some illnesses simply by washing with soap and water. But germs can still enter the body through small cuts in the skin or through the mouth,eyes,and nose.Once germs are inside your body,your immune （免疫的）system tries to protect you. It looks for and destroys germs. How does it do that? Special cells patrol your body. Some of these cells actually eat germs! Other cells make antibodies. An antibody sticks to a germ. There is a different antibody for each kind of germ. Some antibodies keep germs from makingyou sick. Others help your body find and kill germs. After a germ is destroyed,the antibodies stay in your body. They protect you if the same kind of germ comes back. That way you will not get the same illness twice.You can keep your body healthy by eating a nutritious （有营养的） diet to make yourimmune system strong. You can also help your immune system fight germs by gettingvaccinated （接种） Vaccines are medicines. They contain germs that have been killed orweakened. The dead germs can't make you sick. Instead,they cause your body to makeantibodies. If the same germ ever shows up again,then your antibodies attack it.16. Viruses can only live inside people or animals.A RightB WrongC Notmentioned17.

2019年职称英语考试理工类B级阅读理解练习题3Ocean Noise PollutionSome scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings.The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred-twenty decibels on land causes pain to human ears. In water, a decibel level of one-hundred ninety-five would have the same effect.Some scientists have proposed setting a noise limit of one. hundred-twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales (鲸鱼).A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died.The explosions had caused their ears to bleed (出血) and become infected (感染).Many researchers， whose work depends on ocean sounds object to a limit of one-hundred-twenty decibels. They say such a limit is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.41 According to the passage, which of the following is increasingly dangerous to sea creatures?A The sound of a car.B The sound of voices.C Man-made noise pollution.D The sound of steps.42 According to the passage, natural sounds include all of the following EXCEPTA sounds made by animals themselves.B ocean drilling.C underwater, earthquakes.D the breaking of ice fields.43 Which of the following is discussed in the third paragraph?A The same noise level produces a different effect on land and in the ocean.B Different places may have different types of noises.C The decibel is not a suitable unit for measuring underwater noise.D Different ocean animals may have different reactions to noises.44 Which of the following is true of whales?A They won't be confused by noises.B They are deaf to noises.C Their ability to reproduce will be lowered by high-level noises.D Their hearing will be damaged by high-level noises.45 According to the passage, what will scientists most probably do in the future?A They will work hard to reduce ocean noise pollution.B They will protect animals from harmful noises.C They will try to set a limit of 120 decibels.D They will study the effect of ocean noise pollution.41. C 42. B 43. A 44. D 45. B41. C Man-made noise pollution.第一段：Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings.指出了认为的噪声污染引起了海洋生物的危险。

2019年职称英语综合类B级：阅读理解模拟20 Early or Later Day CareThe British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion.转自：考试网 - []Firstly, anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, the father and mother of a child did not rear their infant alone - far from it. Secondly, common sense tells us that day care would not be so widespread today if parents, care-takers found children had problems with it. Statistical studies of this kind have not yet been carried out, and they have uniformly reported that day care had a neutral or slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics.Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.练习：1. Which of the following statements would Bowlby support?A) Statistical studies should be carried out to assess the positive effect of day care for children at the age of three or older.B) Early day care can delay the occurrence of mental illness in children.C) The first three years of one's life is extremely important to the later development of personality.D) Children under three get used to the life at nursery schools more readily than children over three.2. Which of the following is derivable from Bowlby's work?A) mothers should not send their children to day care centers until they are three years or older.B) Day care nurseries have positive effects on a child's development.来自C) A child sent to a day care center before the age of three may have emotional problems in later life.D) Day care would not be so popular if it has noticeable effects on a child's personality.3. It is suggested that modern societies differ from traditional societies in thatA) the parents-child relationship is more exclusive in modern societies.B) a child more often grows up with his/her brothers or sisters in traditional societies.C) mother brings up children with the help of her husband in traditional societies.D) children in modern societies are more likely to develop mental illness in later years.4. Which of the following statements is NOT an argument against Bowlby's theory?A) many studies show that day care has a positive effect on children's development.B) Day care is safe, otherwise there wouldn't be so many nursery schools.C) Separation from parent for very young children is common in some traditional societies.D) Parents find the immediate effects of early day care difficult to deal with.5. Which of the following best expresses the writer's attitude towards early day care?A) Children under three should stay with heir parents.B) Early day care has positive effects on children's development.C) The issue is controversial and its settlement calls for the use of statistics.D) The effects of early day care on children are exaggerated and parents should ignore the issue.Keys：CAADC。

第一篇Will Quality Eat up the U.S. leadin Software?If U. S. software companies don't paymore attention to quality, they could kiss their business good-bye. Both India and Brazil are developing a world-classsoftware industry.Their weapon is quality and one of their jobs is toattractthe top U. S.quality specialists whose voices are not listened to in their country.Already, of the world's 12 software housesthat have earned the highest rating in the world, seven are in India. That's largelybecause they have used new methodologiesrejected by American software specialists.For example, for decades, quality specialists, W. Edwards Deming and J.M.Juran had urged U. S.software companies to change their attitudes to quality. But their quality callmainly fell ondeaf ears in the U. S—but notin Japan.By the 1970s and 1980s, Japanwas grabbing market share with better, cheaper products. They used Deming's andJuran's ideas to bring down the cost of good quality to as little as 5% of totalproduction costs. In U. S.factories, the cost of quality then was 10 times as high：50%. In software, itstill is.Watts S. Humphrey spent 27 years at IBMheading up software production and then quality assurance. But his advice wasseldom paid attention to. He retired from IBM in 1986. In 1987, he worked out asystem for assessing and improving software quality. It has proved its valuetime and again. For example, in 1990 the cost of quality at Raytheon ElectronicsSysterns was almost 60% of total software production costs. It fell to 15% in l996and has since further dropped to below 10%.Like Deming and Juran, Humphrey seems to bewinning more praises overseas than at home. The Indian government and severalcompanies have just founded the Watts Humphrey Software Quality Institute atthe Software TechnologyPark in Chennai, India.Let's hope that U. S.lead in software will not be eaten up by its quality problems.31 What country has more highest-rating companies in the world than anyother country has?A Germany.B The US.C Brazil.D India.32 Which of the following statements about Humphrey is true?A He is now still an IBM employer.B He has worked for IBM for 37 years.C The US pays much attention to his quality advice.D India honors him highly.33 By what means did Japan grab its large market share by the 1970s andthe 1980s?A Its products were cheaper in price and better in quality.B Its advertising was most successful.C The US hardware industry was lagging behind.D Japan hired a lot of Indian software specialists.34 What does the founding of the Watts Humphrey Software QualityInstitute symbolize?A It symbolizes the US determination to move ahead with its software.B It symbolizes the Indian ambition to take the lead in software.C It symbolizes the Japanese efforts to solve the software qualityproblem.D It symbolizes theC hinese policy on importing software.35 What is the writer worrying about?A Many US software specialists are working for Japan.B The quality problem has become a worldwide problem.C The US will no longer be the first software player in the world.D India and Japan are joining hands to compete with the US.第二篇Controlling Robots with theMindBelle, our tiny monkey, was seated in herspecial chair inside a chamber at our Duke Universitylab. Her right hand grasped a joystick as the watched a horizontal series of lightson a display ptanel. She knew that if a light suddenly shone and she moved thejoystick left or right to correspond to its position, she would be sent a dropof fruit juice into her mouth.Belle wore a cap glued to her head. Under itwere four plastic connectors, which fed arrays of microwires—each wire finer than the finest sewing thread—into different regions of Belle's motor cortex, the brain tissuethat plans movements and sends instructions. Each of the 100 microwires laybeside a single motor neuron. When a neuron produced an electrica discharge,the adjacent microwire would capture the current and send it up through a smallwiring bundle that ran from Belle's cap to a box of electronics on a table nextto the booth. The box, in turn, was linked to two computers, one next door andthe other half a country away.After months of hard work, we were about totest the idea that we could reliably translate the raw electrical activity in livingbeing's brain—Belle's mere thoughts—into signals that could direct the actions of a robot. We had assembleda multi jointed robot arm in this room, away from belle's view, that she wouldcontrol for the first time. as soon as Belle'sbrain sensed a lit spot on thepanel, electronics in the box running two real—timemathematical models would rapidly analyze the tiny action potentials producedby her brain cells. Our lab computer would convert the electrical patterns thatwould direct the robot arm. Six hundred miles north, in Cambridge, Mass, a different computer wouldproduce the same actions in another robot arm built by Mandayam A.Srinvasan.If we had done everything correctly, the two robot arms would behave as Belle'sarm did, at exactly the same time.Finally the moment came. We randomly switchedon lightsin front of Belle, and she immediately moved her joystickback andforth to correspond to them. Our robot arm moved similarly to Belle's real arm.So did Srinivasan's Belle andthe robots moved in synchrony, like dancerschoreographed bythe electrical impulses sparking inn Belle's mind.In the two years since that day, our labs andseveral others have advanced neuroscience, computer science and microelectronicsto.create ways for rats, monkeys andeventually humans to control mechanicaland electronic machines purely by “thinking through,” or imagining, themotions. Our immediate goal is to help a person who has been unable to move bya neurological disorder or spinal cord injury, but whose motor cortex isspared, to operate a wheelchair or a robotic limb.36 Belle would be fed some fruit juice if she__________.A moved the joystick according to what she heardB watched lights on a display panelC sat quietly in a special chairD moved the joystick to the side of the light37 According to the second paragraph, the wires fixed under the cap Bellewore were connected to __________.A a box of electronics and two computersB a booth and two computersC a box which, in turn, was linked to two computersD a computer half a country away38 Which of the following statements is NOT true of the robot arm builtby Srinivasan? __________A It was six hundred miles away from where belle was.B It was directed by electric signals converted from the electricalactivity in Belle's brain.C It could produce the same actions as another robot arm.D It could convert the electrical patterns into instructions for anotherrobot arm.39 Which of the following statements indicates the success of theexperiment? (the 4th paragraph) __________.A Belle responded to the robot arms successfully.B The two robot arms moved the joysticks in time.C The two robot arms and Belle corresponded to the lights at the samerate.D Belle and the two robot arms were like impulsive dancers.40 The final aim of the research was to help a person __________.A who is unable to move but whose motor cortex is not damagedB who can operate a wheelchair or a robotic limbC whose motor cortex is damagedD who has spinal cord injury but is able to move a wheelchair第三篇Electronic Mail (E-mail)During the past few years, scientists the worldover have suddenly found themselves productively engaged in task they oncespent their lives avoiding-writing, anykind of writing, but particularly letter writing. Encouraged by electronic mail'ssurprisingly high speed, convenience and economy, people who never beforetouched the stuff are regularly, skillfully, even cheerfully tapping out agreat deal of correspondence.Electronic networks, woven into the fabric ofscientific communication these days, are the route to colleagues in distantcountries, shared data, bulletin boards and electronic journals. Anyone with apersonal computer, a modem and the software to link computers over telephone linescan sign on. An estimated five million scientists have done so withmorejoining every day, most of them communicating through a bundle of interconnecteddomestic and foreign routes known collectively as the Internet, or net.E-mail is starting to edge out the fax, thetelephone,overnight mail, and of course, land mail. It shrinks time and distance betweenscientific collaborators, in part because it is conveniently asynchronous(writers can type while their colleagues across time zones sleep; their messagewill be waiting). If it is not yet speeding discoveries, it is certainly acceleratingcommunication.Jeremy Bernstei, the physicist and sciencewriter, once called E-mail the physicist's umbilical cord. Lately other people,too, have been discovering its connective virtues. Physicists are using it; collegestudents are using it, everybody is using it, and as a sign that it has come ofage, the New Yorker has celebrated its liberating presence with a cartoon-an appreciative dog seated at a keyboard, saying happily, “On theInternet, nobody knows you're a dog.”41 The reasons given below about the popularity of E-mail can be foundin the passage EXCEPT __________.A direct and reliableB time-saving in deliveryC money-savingD available at any time42 How is the Internet or net explained in the passage? __________A Electronic routes used to read home and international journals.B Electronic routes used to fax or correspond overnight.C Electronic routes waiting for correspondence while one is sleeping.D Electronic routes connected among millions of users, home andabroad.43 What does the sentence “If it is not yet speeding discov eries, it iscertainly accelerating communication” most probably mean? __________A The quick speed of correspondence may have ill-effects ondiscoveries.B Although it does not speed up correspondence, ithelps makediscoveries.C It quickens mutual communication even if it does not acceleratediscoveries.D It shrinks time for communication and accelerates discoveries.44 What does the sentence “On the Internet, nobody knows you're a dog.”implyin the last paragraph? __________A Even dogs are interested in the computer.B E-mail has become very popular.C Dogs are liberated from their usual duties.D E-mail deprives dogs of their owners' love.45 What will happen to fax, land mail, overnight mail, etc. accordingto the writer? __________A Their functions cannot be replaced by E-mail.B They will co-exist with E-mail for a long time.C Less and less people will use them.D They will play a supplementary function to E-mail.。
