职称英语考试《理工类》模拟试题及答案0510-561、English and English Community1 There is no doubt that English is a useful language. The people who speak English today make up the largest speech community in the world with the exception of speakers of Chinese.2 A speech community is similar to other kinds of communities. The people who make up the community share a common language. Often they live side by side, as they do in a neighborhood, a village, or a city. More often they form a whole country. National boundaries, however, are not always the same as the boundaries of a speech community. A speech community is any group of people who speak the same language no matter where they happen to live.3 We may say that anyone who speaks English belongs to the English speech community. For convenience, we may divide the speakers into two groups: one in which the speakers use English as their native language, the other in which the speakers learnEnglish as a second language for the purpose of education, commerce, and so on.4 Learning a second language extends one's vision and expands the mind. The history and literature of a second language record the real and fictional lives of people and their culture; a knowledge of them adds to our ability to understand and to feel as they feel. Learning English as asecond language provides another means of communication through which the window of the entire English speech community becomes a part of our heritage.Overall there are more speakers of Chinese than of____.【单选题】A.a second languageB.the same languageC.the same speech communityD.any other languageE.national boundariesF.a part ofone's heritage正确答案:D答案解析:从文章第1段可知，说汉语的人比说任何其他语言的人都要多。

Newspapers often tell us of floods in some parts of the United States.Nearly every year on the great central drainages heavy rains and melting snow cause the waters to pour out the mountains and plains, to turn brooks into torrents, and to swell quiet streams into wild uncontrolled rivers. From Cairo to New Orleans, and from Pittsburgh to Paducah, the cry "River rising!" is a familiar yet fearful voice. . . When the rivers sometimes become too high or too swift to becontrolled communities are flooded, families flee from their homes, croplands are washed out, and transportation comes to a halt. Hunger, disease, and death follow the wild waters.Although given less publicity, the agricultural damage done by the many smaller, more frequent floods usually far exceeds the losses caused by the very grand ones. In the Central States, ditches and drains cause the flows from spring rains and melting snow to run far more rapidly than in the days before white men settled on the land. Once, excess spring flood waters emptied into lakes and swampy lands, there to be detained for slow release into stream and rivers. Now, systematic drainage has actually eliminated thesenatural reservoirs.In the more rolling sections of the East, spring runoff was formerly absorbed and held temporarily in the poroussoils beneath the unbroken expanse of forest. When large areas were converted to farm use, removal of the forest and the practice of up-and-down hill plowing deprived the soils of much of their ability to catch and store water.The effects of eliminating the natural forest cover are shown in the gullied farm lands and widened stream channels found in some densely settled areas. Partly because the stream channels are more or less filled with material washed down from the uplands, and partly because storm runoff has increased, the channels are today no longer able to carry all the flow from heavy rains. This explains why the streams overtop banks far more often than in the days before settlement.31. The best title for the selection would be______.A. River Rising! River Rising!B. Forests and FloodsC. Flooding in the U. S.D. The Results of Flooding32. All of the following cause floods EXCEPT______.A. heavy rainB. melting snowC. increasing storm runoffD. porous soil33. The author states that______.A. lakes and swamps once acted like natural reservoirsB. up-and-down hill plowing catches and stores waterC. stream channels are the best carriers of waterD. floods are easily prevented and controlled34. According to the selection, streams overtop their banks partly because______.A. material from higher land is washed into themB. ditches and drains lead into themC. rivers become too swiftD. snow melts more rapidly nowadays35. The floods which are given most publicity______.A. cause no damageB. cause the most damageC. cause less agricultural damage than the many smaller, more frequent floodsD. far exceed the smaller, more frequent floods in agricultural lossMobile Phone and DiseasesA study by scientists in Finland has found that mobile phone radiation can cause changes in human cells that might affect the brain, the leader of the research team said.But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec(魁北克), said more research was needed to determine the seriousness of the changes and their impact on the brain or the body.The study at Finland's Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown in a laboratory, he said.“We know that there is some biological response. We can detect it with our very sensitive approaches, but we do not know whether it can have any physiological effects on the human brain or human body,” Leszczynski said.Nonetheless the study, the initial findings of which were published last month in the scientific journal Differentiation, raises new questions about whether mobile phone radiation can weaken the brain's protective shield against harmful substances.The study focused on changes in cells that line blood vessels and on whether such changes could weaken the functioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from the bloodstream, Leszczynski said.The study found that a protein called hsp27 linked to the functioning of the blood-brain barrier showed increased activity due to irradiation and pointed to a possibility that such activity could make the shield more permeable(能透过的), he said.“Increased protein activity might cause cells to shrink—not the blood vessels but the cells themselves—and then tiny gaps could appear between those cells through which some molecules could pass. ” he said.Leszczynski declined to speculate on what kind of health risks that could pose, but said a French study indicated that headache, fatigue and sleep disorders could result.“These are not life-threatening problems but can cause a lot of discomfort,” he said, ad ding that a Swedish group had also suggested a possible link with Alzheimer's disease.“Where the truth is do not know,” he said.Leszczynski said that he, his wife and children use mobile phones, and he said that he did not think his study suggested any need for new restrictions on mobile phone use.36 According to Leszczynski, how does mobile phoneaffect one's health? _________A Mobile phone radiation can increase protein activities and such activities can make the protective shield more permeable.B Mobile phone radiation can shrink the blood vessels and prevent blood from flowing smoothly.C Mobile phone radiation will bring stress to people exposed to it.D Mobile phone radiation kills blood cells at a rapid speed.37 What's the result of the French study? _________A The harm of mobile phone radiation is life-threatening.B Mobile phone may affect one's normal way of thinking.C Sleep disorders could result from mobile phone radiation.D A protein called hsp27 is killed by mobile phone radiation.38 What kind of disease is not caused by the use of mobile phone? _________A Fatigue.B Headache.C Alzheimer's disease.D Tuberculosis.39 According to the passage, what would be the future of the use of mobile phone? _________A People will be forbidden to use mobile phone.B People dare not use mobile phone because of its radiation.C People will continue to use mobile phone.D There will be new restrictions on the use of mobile phone.40 Which of the following is NOT true according to the passage? _________A The research in Finland found that mobile phone radiation will affect one's brain.B Mobile phone radiation can cause increased activity in hundreds of protein in human cells.C Increased protein activity might cause cells to shrink.D Lszczynski forbid his wife and children to use mobile phone after his research.Electronic Mail (E-mail)During the past few years, scientists the world over have suddenly found themselves productively engaged in task they once spent their lives avoiding-writing, any kind of writing, but particularly letter writing. Encouraged by electronicmail's surprisingly high speed, convenience and economy, people who never before touched the stuff are regularly, skillfully, even cheerfully tapping out a great deal of correspondence.Electronic networks, woven into the fabric of scientific communication these days, are the route to colleagues in distant countries, shared data, bulletin boards andelectronic journals. Anyone with a personal computer, a modem and the software to link computers over telephone lines can sign on. An estimated five million scientists have done so with more joining every day, most of them communicating through a bundle of interconnected domestic and foreignroutes known collectively as the Internet, or net.E-mail is starting to edge out the fax, the telephone, overnight mail, and of course, land mail. It shrinks time anddistance between scientific collaborators, in part because it is conveniently asynchronous (writers can type while their colleagues across time zones sleep; their message will be waiting). If it is not yet speeding discoveries, it is certainly accelerating communication.Jeremy Bernstei, the physicist and science writer, once called E-mail the physicist's umbilical cord. Lately other people, too, have been discovering its connective virtues. Physicists are using it; college students are using it, everybody is using it, and as a sign that it has come of age, the New Yorker has celebrated its liberating presence with a cartoon-an appreciative dog seated at a keyboard, saying happily, “On the Internet, nobody knows you're a dog.”41 The reasons given below about the popularity of E-mail can be found in 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 and abroad.43 What does the sentence “If it is not yet speeding discoveries, it is certainly accelerating communication” most probably mean? __________A The quick speed of correspondence may have ill-effects on discoveries.B Although it does not speed up correspondence, it helps make discoveries.C It quickens mutual communication even if it does not accelerate discoveries.D It shrinks time for communication and accelerates discoveries.44 What does the sentence “On the Internet, nobody knows you're a dog.”imply in 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. according to 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.31.

2012年职称英语综合类教材新增内容：阅读理解篇8

/english/zhicheng/ziliao/ zh/2012年职称英语综合类教材新增内容：阅读理解篇1第一篇Telling Tales about PeopleOne of the most common types of nonfiction, and one that many people enjoy reading, is stories about people's lives. These stories fall into three general categories: autobiography, memoir, and biography.An autobiography is the story of a person's life written by himself or herself. Often it begins with the person's earliest recollections and ends in the present. Autobiography writers may not be entirely objective in the way they present themselves. However, they offer the reader a good look at the way they are and what makes them that way. People as diverse as Benjarmin Franklin and Helen Keller have written autobiographies. 1Other writers, such as James Joyce，have written thinly fictionalized accounts of their lives. These are not autobiographies，but they are very close to it.Memoirs, strictly speaking, are autobiographical accounts that focus as much on the events of the times as on the life of the author. 2Memoir writers typically use these events as backdrops for their lives. They describe them in detail and discuss their importance. Recently，though，the term memoir seems to be becoming interchangeab1e with autobiography. A memoir nowadays may or may not deal with the outside world.Biographies are factual accounts of someone else's life. In many senses，these may be the hardest of the three types to write. Autobiography writers know the events they write about because they lived them. But biography writers have to gather information from as many different sources as possible. Then they have to decide which facts to include. Their goal is to present a balanced picture of a person，not one that is overly positive or too critical. A fair well-presented biography may take years to research and write.词汇：backdrop /'bæk,drɔp/ n. 背景interchangeable /intə 'tʃendʒəbl/ adj. 可转换的注释：1. People as diverse as Benjamin Franklin and Helen Keller have written autobiographies. 就像本杰明•富兰克林和海伦•凯勒一样，各种各样的人们已经写了自传。

Ford has now announced it will do the same.Three years ago，the company introduced the Think City two-seater car and a golf cart called the THINK, or Think Neighbor6. It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1，700 carts have been sold so far in 2002."The bottom line is7 we don't believe that this is the future of environment transport for the mass market," Tim Holmes of Ford Europe said on Friday. "We feel we have given electric our best shot8. ”The Think City has a range of only about 53 miles and up to a six-hour battery recharge time. General Motors' EVI electric vehicle also had a limited range, of about 100 miles.The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota9 RA V4 EV vehicle costs over $42,000 in the US, compared with just $17,000 for the petrol version. Toyota and Nissan10 are now the only major auto manufacturers to produce electric vehicles."There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program11, and that is what we will be judging them on, ”Roger Higman，a senior transport campaigner at UK Friends of the Earth, told the Environment News Service.Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol-only engines, and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines12 on vehicle emissions13 in the US. However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler14 won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 100,000 zero-emission and other low-emission vehicles in the stateby 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.词汇：hybrid /'haibrid/ n.杂种，混合物；adj.杂种mileage /'mailids/ n.英里数，英里里程的；混合的injunction/iidsAgkJ^n/n.命令；指令注释：1.

2020年职称英语理工类阅读理解考试模拟题(8)

2020年职称英语理工类阅读理解考试模拟题(8)A ride in a cable-car is one of the exciting andenjoyable experiences a child can have. In Switzerland, which is the home of the cable-car, it is used mostly to taketourists up the slope of a mountain, to a restaurant from which one can have a bird-eye view of the surrounding country, or to a top of a ski-run, from which, in winter, skiers glide down the snow covered the slope on skis. In Singapore, however, the cable-car takes one from the summit of a hill on the main island to a low hill on Sentosa, a resort islandjust off the southern coast.The cable-car is really a carriage which hangs from a strong steel cable suspended in the air. It moves along the cable with other cars on pulleys, the wheels of which are turned by electric motors. The cars are painted in eye-catching colours and spaced at regular intervals. Each carcan seat up six persons. After the passengers have entered a car, they are locked in from outside by an attendant, they have no control over the movement of the car.Before long, the passengers get a breath-taking view through the glass windows of the modern city, the bustling harbour, and the several islands off the coast. The car is suspended to a high in the air that slips on the sea looklike small boats, and boats like toys. On a clear day, boththe sky above and the sea below look beautifully blue.In contrast to the fast-moving traffic on the ground, the cars in the air move in a leisurely manner, allowing passengers more than enough time to take in the sceneryduring the brief trip to the island of Sentosa. After a few hours on Sentosa, it will be time again to take a cable-car back to Mount Faber. The return journey is no less exciting than the outward trip.1. The cable-car in SingaporeA)takes visitors up to a mountain restaurant.B)takes skiers to the top of a ski-run.C)takes visitors to Sentosa.D)takes visitors to a high mountain.2. Which of the following about the cable-cars is true?A)The cars move along the steel cable.B)The cars are operated by a driver.C)The cars are controlled by the passengers.D)The cars move on wheels.3. Passengers can get a breath-taking view when riding ina cable-car becauseA)The car is painted in eye-catching colours.B)The car is suspended so high in the sky.C)Each car can seat up to six persons.D)Both the sky and the sea look beautifully blue.4. The short trip does not bother passengers who want a good view becauseA)the cars move slowly.B)the cars move quickly.C)the cars are suspended very high.D)the cars have glass windows.5.

2014职称英语新增文章——理工类B级完美版(已排版、含译文、含完整解答)

2014职称英语教材理工类B级新增文章一、阅读判断第8篇：What Is a Dream?（B级）What Is a Dream?For centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning. Others, however, think that dreams are an important part of our lives. In fact, many experts believe that dreams can tell us about a person's mind and emotions.Before modem times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way.The Austrian psychologist, Sigmund Freud, was probably the first person to study dreams scientifically. In his famous book, The interpretation of Dreams ( 1900 ), Freud wrote that dreams are an expressions of a person's wishes. He believed that dreams allow people to express the feelings, thoughts, and fears that they are afraid to express in real life.The Swiss psychiatrist Carl Jung was once a student of Freud' s. Jung, however, had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. He thought people could learn more about themselves by thinking about their dreams. For example, people who dream about falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves.Modem-day psychologists continue to develop theories about dreams. For example, psychologist William Domhoff from the University of California, Santa Cruz, believes that dreams are tightly linked to a person's daily life, thoughts, and behavior. A criminal, for example, might dream about crime.Dornhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults. According to Domhoff, dreaming is a mental skill that needs time to develop.He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. For example, the people in men's dreams are often other men, and the dreams often involve fighting. This is not true of women's dreams.3 Domhoff found this gender difference in the dreams of people from 11 cultures around the world, including both modem and traditional ones.Can dreams help us understand ourselves? Psychologists continue to try to answer this question in different ways. However, one thing they agree on this: If you dream that something terrible is going to occur,you shouldn't panic. The dream may have meaning, but it does not mean that some terrible event will actually take place. It's important to remember that the world of dreams is not the real world.词汇：psychologist n.心理学家 psychiatrist n.精神病学家（医生）Austrian adj.奥地利的 gender n.性别注释：1.SigmundFreud西格蒙德.费洛伊德(1856-1939)，犹太人，奥地利精神病医生及精神分析学家。

2020职称英语阅读判断模拟题及答案《理工类》(8)

2020职称英语阅读判断模拟题及答案《理工类》(8)One day in 1963, a dolphin named Elvar and a famous astronomer, Carl Sagan, were playing a little game. The astronomer was visiting an institute which was looking into the way dolphins communicate with each other. Sagan was standing on the edge of one of the tanks where several of these friendly, highly intelligent creatures were kept. Elvar had just swum up alongside him and had turned on his back.The dolphin wanted Sagan to scratch his stomach again, as the astronomer had done twice before. Elvar looked up at Sagan, waiting. Then, after a minute or so, the dolphin leapt up through the water and made a sound just like the word "more". The astonished astronomer went to the director of the institute and told him about the incident. "Oh, yes. That's one of the words he knows," the director said, showing no surprise at all.Dolphins have bigger brains in proportion to their body size than humans have, and it has been known for a long time that they can make a number of sounds. What is more, these sounds seem to have different functions, such as warning each other of danger. Sound travels much faster and much furtherin water than it does in air. That is why the parts of the brain that deal with sound are much better developed in dolphins than in humans. But can it be said that dolphins have a 'language', in the real sense of the word? Scientists don't agree on this.A language is not just a collection of sounds, or even words. A language has a structure and what we call a grammar.The structure and grammar of a language help to give it meaning. For example, the two questions 'Who loves Mary?' and 'Who does Mary love?' mean very different things. If you stop to think about it, you will see that this difference doesn't come from the words in the question but from the difference in structure. That is why the question 'Can dolphins speak?' can't be answered until we find out if dolphins not only make sounds but also arrange them in a grammatical order which affects their meaning.1 The astronomer was not interested in the way dolphins communicate with each other.A RightB WrongC Not mentioned2 The dolphin leapt up into the air because Sagan was too near the water.A RightB WrongC Not mentioned3 Parts of the dolphin's brain are particularly well developed to handle different kinds of sound.A RightB WrongC Not mentioned4 Dolphins are the most useful animals to humans.A RightB WrongC Not mentioned5 Dolphins travel faster in water than any other animals.A RightB WrongC Not mentioned6 Some scientists believe that dolphins have a language of their own.A RightB WrongC Not mentioned7 Sounds can be called a language only when they have a structure and a grammar.A RightB WrongC Not mentioned【参考答案】1.
