xx年职称英语考试《理工类》模拟试题Major panies are already in pursuit of mercial applications of the new biology. They dream of placing enzymes(酶) in the automobile to monitor exhausts and send data on pollution to a microprocessor(微处理机) that will then adjust the engine. They speak of what the New York Times calls "metal-hungry microbes(渴望吃金属的微生物)that might be used to mine valuable trace metals from ocean water". They have already demanded and won the right to patent newlifeforms.Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientifiC.rivalry in the entire biotechnological(生物工艺学) field. They create images not of oil spills, but of "microbe spills'" that could spread disease and destroy entire populations. The creation and aidental release of extremely poisonous microbes, however, is only one causefor alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination.Should we breed people with cow-like stomachs so they can digest grass and hay, thereby relieving the fOodproblem by modifying us to eat lower down on the food chain? Should we biologically alter workers to fit thejoB.requirement, for example, creating pilots with fasterreaction times or assembly-line workers designed to do our monotonous work for us? Should we attempt to eliminate "inferior" people and breed a "super-race"? (Hitler tried this, but without the geiC.weaponry that may soon issue from our laboratories. ) Should we produce soldiers to do our fighting? Should we use geiC.forecasting to pre-el!minate "unfit" babies? Should we grow reserve organs for ourselves, each of us having, as it were, a "savings bank" full of spare kidneys, livers or hands?Wild as these notions may sound, every one has its advocates (and opposers) in the scientifiC.munity as well as its striking mercial application. As two critics of geiC.engineering,Jeremy Rifkin and Ted Howard, state in their book Who Should Play God? "Broad scalegeiC.engineering will probably be introduced to America much the same way as assembly lines, auto-mobiles, vaines, puters and all the other technologies.. As each newgeiC.advance bees mercially practical, a new consumer need will be exploited and a market for the new technology will be created.

Save your voice for your health. You may feelfoolish using paper towrite notes, but the best thing you can do is to rest your voice. If it is necessary, perhaps you canget some advice from aprofessional singer.What about drinking alcohol to wet your throat? Iadvice you not to touch alcohol beforespeaking. The problem with alcohol is that one drink gives you alittle confidence. The seconddrink gives you even more confidence.

职称英语考试《理工类》模拟试题及答案0510-221、Cell Phone Lets Your Secret OutYour cell phone holds secrets about you. Besides the names and numbers that you've programmed into it, traces of your DNA linger on the device, according to a new study.DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you-because you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims. Your cell phone can reveal more about you than you might think. Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. So she and colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs tocollect invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user's ear.The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more.The scientists discovered DNA that belonged to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device. So cell phones can now be added to the ______ of clues that can clinch a crime scene investigation.【单选题】A.explanationB.discoveryC.bookD.list正确答案:D答案解析:根据上下文的理解，应该选择list，其他三个选项与句子的意思不符。

职称英语理工类模拟试题及答案以下是的理工类模拟试题及答案，希望对大家有所帮助The Education of Benjamin FranklinHistory has given Benjamin Franklin a place of enduring fame. He was a writer, an inventor, a scientist, and a statesman. His life history has enjoyed popular suess for more than 200 years.Franklin's education at school stopped when he was ten years old. But he never stopped learning. For him, books held the key to living happily and suessfully. They were precious gifts.In his early youth, he had a friend who worked for a bookseller. Sometimes his friend would lend him books, which he was careful to return quickly. Often he sat up in his room reading most of the night in order to return a book before his friend's employer noticed its absence.But Franklin was not a lonely scholar. For him, learning was a social experience. In his Autobiography, he tells about organizing a club called the "Junto", which met every Friday night to improve its members' minds: "The rules I made required every member, in turn, to produce one or more questions on any point of Morals, Politics, or Natural Philosophy. The question would then be discussed by the whole group. Also, once in three months,each member was required to read an article he had written on any subject he pleased."Our discussions were directed by a president and conducted as an honest search for truth. We were to avoid unpleasant arguments or a desire for victory. Any member who did not obey these rules had to pay a fine."The Junto which Franklin organized continued for many years. It was the best group for the discussion then. The questions were given to the members during the week before they were to be discussed. This encouraged the members to read carefully about each subject so that they might speak with more understanding.When the Junto was organized, before the middle of the 18th century, there were no public libraries. There was not even a good bookstore south of Boston. Franklin decided to improve this situation.Each member of the Junto owned a few books. A room had been rented in which the members held the meetings. Franklin suggested that all the members should bring their books to the room. In this way the book would be a help to all during the weekly discussion. Also, each member would be allowed to take and read at home any book be chose.Throughout his life, Benjamin Franklin continued his education, learning from human contacts as well as from books.1.

Around the world, people are starting to measure the effects of global warming - and trying to figure out what to do about it.Scientists recently used satellites to study the temperatures of lakes around the world, and they found that lakes are heating up.Between 1985 and , satellites recordedthe nighttime temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer - by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius, or 1.8 degrees Fahrenheit, in just 10 years. That difference may seem small - you might not even notice it in your bathtub. But in a lake, slightly warmer temperatures could mean more algae, and algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how the Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming.The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That's going to be useful, since no country is too big or too small to ignore climate change. Scientists aren't the only ones concerned. Everyone who lives on Earth is going to be affected by therapidwarming of the planet.Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse gases we put into the air.That's why the United Nations started the Framework Convention on Climate Change, or UNFCCC. Every year the convention meets, and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.16 Scientist have been keeping records of lake temperatures for over 30 years.A RightB WrongC Not mentioned17 The temperatures of lakes around the world have increased greatly between 1985 and .A RightB WrongC Not mentioned18 Lakes seem to be warming faster in Asia.A RightB WrongC Not mentioned19 A slight temperature increase in a lake could be harmful to fish.A RightB WrongC Not mentioned20 Scientists generally focus on air temperatures when studying global warming.A RightB WrongC Not mentioned21 Globle warming is less threatening to small countries.A RightB WrongC Not mentioned22 UNFCCC's annual meeting will be held in Mexico this year.A RightB WrongC Not mentioned第3部分：概括大意与完成句子（第23～30题，每题1分，共8分）下面的短文后有2项测试任务：（1）第23～26题要求从所给的6个选项中为第2～5段每段选择1个最佳标题；（2）第27～30题要求从所给的6个选项中为每个句子确定一个最佳选项。

职称英语试题理工类复习模拟题含答案
职称英语试题理工类复习模拟题含答案When We Are AsleepEveryone dreams，but some people never recall their dreams，or do so very rarely. Other people always wake up with vivid recollections (记忆) of their dreams，though they forget them very quickly. In an average night of eight hours' sleep，an average adult will dream for around one hundred minutes，probably having three to five dreams，each lasting from ten to thirty minutes. Scientists can detect when someone is having a dream by using an instrument which measures the electrical waves in the brain. During dreaming, these waves move more quickly. Breathing and pulse rate also increase，and there are rapid eye movements under the lids, just as though the dreamer were really looking at moving objects. These signs of dreaming have been detected in all mammals (哺乳动物) studied, including dogs, monkeys, cats, and elephants, and also some birds and reptiles (爬行动物). This period of sleep is called the "D" state for around 50% of their sleep;the period reduces to around 25% by the age of 10.Dreams take the form of stories，but they may be strange and with incidents not connected，which make little sense. Dreams are seldom without people in them and they are usually about people we know. One estimate says that two-thirds of the "cast" of our dream dramas are friends and relations. Vision seems an essential part of dreams，except for people blind from birth. Sound and touch are senses also often aroused，but smell and taste are not frequently involved. In "normal" dreams，the dreamer may be taking part，or be only an observer. But he or she cannot control what happens in the dream.However, the dreamer does have control over one type of dream. This type of dream is called a "lucid"(清醒的) dream. Not everyone is a lucid dreamer. Some people are occasional lucid dreamers. Others can dream lucidly more or less all the time. Ina lucid dream，the dreamer knows that he is dreaming.16.Some people dream but cannot remember their dreams.A. RightB. WrongC. Not mentioned17.In an average night，males dream longer than females.A.

Not mentioned答案: 16.A 17.C 18.B 19.B 20.C 21.A 22.CIt's in the CardsIn recent years, more and more people have been paying for things with credit cards. There are now 565 million credit cards worldwide, but it doesn't stop there. Debit cards (电子记账卡) are being issued by banks, and store cards are being offered by many department stores. Bills and coins are gradually being replaced by "plastic money." In many countries, phone cards have beenintroduced for people to use in pay phones. In addition, cards made of paper are being replaced by plastic ones by many organizations and clubs. For example, if you belong to a sports club, your membership card may well be made of plastic.How safe is the plastic used to make these cards, though? Until now, most cards have been made from a plastic called PVC. While PVC is being produced, harmful chemicals are released into the atmosphere. One of the most dangerous chemicals that is released is dioxin, which is known to cause cancer in humans. A further problem is that, when a PVC card is thrown away, it is not biodegradable; this means that it does not "break down" and cannot be recycled. Obviously, recycling reduces pollution of the environment.The executive director of the environmental organization and charity Greenpeace, Peter Melchett, says, "If there is a solution to this - and an alternative then it would be madness not to use it." Greenpeace has found a solution and an alternative. Their new credit card is made entirely from a biodegradable plastic that uses plants. The card breaks down in around three months in soil; in this way, it is recycled. In contrast, a PVC card lasts for centuries Greenpeace hopes that many organizations will soon follow their example and issue cards that do not threaten the public health.1 Fewer and fewer credit cards are made of paper,A RightB WrongC Not mentioned2The plastic used in credit cards is fairly safe.A RightB WrongC Not mentioned3The cards that are wildly used now are credit cards.A RightB WrongC Not mentioned4Most credit cards are biodegradableA RightB WrongC Not mentioned5 The new credit card that is being introduced by Greenpeace is not made of plastic.A RightB WrongC Not mentioned6 The new Greenpeace card breaks down in a few monthsA RightB WrongC Not mentioned7 Greenpeace cards are widely used in many organizations now.A RightB WrongC Not mentioned答案:1. A2. B3. C4. B5. B6. A7. BThe First settlement in North AmericaIt is very difficult to say just when colonization began. The first hundred years after Christopher Columbus's journey of discovery in 1492 did not produce any settlement on the North America continent but rather some Spanish trading posts further south, a great interest in gold and adventure, and some colorful crimes in which the English had their part. John Cabot, originally from Genoa but a citizen of Venice, was established as a trader in Bristol, England, when he made a journey in 1497. But his ship, the Matthew, with its crew of eighteen, did no more than see an island (probably off the New England coast) and return home. He and his son made further voyages across the north Atlantic which enabled the English crown to claim a "legal" title to North America. But for a long time afterwards the Europeans' interest in America was mainly confined to the Spanish activities further south.The first beginning of permanent settlement in North America were nearly a hundred years after Columbus's first voyage. The Englishman Sir Walter Raleigh claimed the whole of North America for England, calling it Virginia. In 1585 he sent asmall group of people who landed in Roanoke Island, but they stayed only for a year and then went back to England with another expedition, led by Drake, in 1587. A second group who landed in 1587 had all disappeared when a further expedition arrived in 1590.The first permanent settlement in North America was in 1607. English capitalists founded two Virginia companies, a southern one based in London and a northern one based in Bristol. It was decided to give the name New England to the northern area. The first settlers in Virginia were little more than wage slaves to the company. All were men and the experiment was not very successful. Many died. Those who survived lived in miserable conditions. By 1610 the colony had only a thousand people.1. We know for sure that colonization began at the end of the 15th centuryA. RightB. WrongC. Not mentioned2.

职称英语考试《理工类》模拟试题及答案0510-201、Black HolesMost scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球体). Astronomers (天文学家) think that at the center of a black hole there is a single point in space with infinite (无限的) density (稠密).This single point is called a singularity (奇点). If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point. Anything that crosses the black hole is pulled in by its great gravity.Although black holes do exist, they are difficult to observe. These are the reasons,?No light or anything else comes out of black holes. As a result, they are invisible to a telescope.?In astronomical terms, black holes are truly. For example, a black hole formed by the collapse of a giant star would have an event horizon (视界) only 18 miles across.?The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion (万亿) miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however, so black holes remain one of the mysteries of the universe.

职称英语《理工类》模拟题带答案Earthquake1.Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of theworld.Most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe.Some of the destruction is directly caused by the quake itself.An example of this is the collapse of buildings as a result of the quake itself.Other damage results from landslides or major fires which are initiated by the quake.2.There are about a million quakes ayear.Fortunately,however,not all of them are destructive.The intensityof an earthquake is measured on the Richter Scale,which goes from 0 upward.The highest scale recorded to date is 8.9.Major damage generally occurs from quakes ranging upwards from 6.0.3.The actual cause of the quake itself is the breaking of rocks at or below the earth's surface.This is produced by pressure which scientists believe may be due to a number of reasons,two of which arethe expansion and contraction of the earth's crust and continental drift.4.In order to limit the damage and to prevent some of the suffering resulting from earthquakes,scientists are working on ways to enable accurate prediction.Special instruments are used to help people record,for example,shaking of the earth.Scientists are trying to find methods that will enable them to indicate the exact time,location and size of an earthquake.5.Certain phenomena have been observed which are believed to be the signs of imminent earthquakes.These include strange behaviors of some animals,the changes in the content of mineral water,etc.The magnetic properties of rocks may also display special pattern before major earthquakes happen.23.Paragraph 2 __________24.Paragraph 3 __________25.Paragraph 4 __________26.Paragraph 5 __________A.Earthquake's ForecastB.Historical Records of EarthquakesC.Intensities o{EarthquakesD.Cause of EarthquakesE.Indications of EarthquakesF.Damaging Earthquakes27.Not all damage during an earthquake is caused __________.28.Not all earthquakes are strong enough __________.29.Scientists have been working hard to warn people __________.30.Earthquakes can be predicted by observing __________.A.by the quake itselfB.not be preventedC.to cause damage of property and loss of livesD.of a possible earthquakeE.the unusual behaviors of some animalsF.the strong behaviors of human beings参考答案：23.C 本段简述在里氏震级表上反映出来的不同震级。

The first comprehensive study on the nation's oral health，released recently by the Office of the U.S. Surgeon General，calls dental and oral disea ses a “silent epidemic (流行病)，” even in children. The report states that more than 51 million school hours are lost each year to dental-related illness. In fact，a recent study pointed to dental care as the most common unmet health need among American children.To help counter this，the American Academy of Periodontology (牙周病学)(AAP)is launching an effort to educate children and parents about the prevention of dental diseases in children.“This is important because oral problems can impact self-esteem for children and lead to problems of eating，speaking and attending to learning，” said Michael McGuire，president of the AAP.Common dental problems seen in children are cavities (龋洞)and gingivitis (龈牙)，which are found in the majority of U.S. children. “When these pr oblems are not caught early and treated，they can develop into more severe problems and cause unnecessary suffering，” said McGuire “However，much of the time，oral problems are avoidable problems.”In the Rio Grande Valley in Texas，a group of more than 120 dentists volunteers to deliver dental care to thousands of low-income children each year with its Mobile Dental Unit that travels from school to school.“According to the Surgeon General's Report，about 37 percent of children have not had a dental visit before starting school，” said McGuire. “When children don't see dentists theymiss the opportunity to have problems caught early before they develop into larger，more expensive problems to treat，and parents miss the opportunity to learn how to promote good oral habits in their children.”16 Only in February should attention be paid to children's oral healthA RightB WrongC Not mentioned17 Dental and oral diseases are common in both adults and childrenA RightB WrongC Not mentioned18 Boys miss more school hours each year due to dental-related illnessA RightB WrongC Not mentioned19 Oral problems in children can develop into more severe problems.A RightB WrongC Not mentioned20 Oral problems can not be avoided in any wayA RightB WrongC Not mentioned21 The low-income children are very grateful to the dentists.A RightB WrongC Not mentioned22 Some children have never seen a dentist before starting school.A RightB WrongC Not mentioned第3部分：概括大意与完成句子(第23～30题，每题1分，共8分)下面的短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第1～4段每段1选择个最佳标题;(2)第27～30题要求从所给的6个选项中为每个句子确定1个最佳选项。

职称英语考试《理工类》模拟试题及答案0510-221、Cell Phone Lets Your Secret OutYour cell phone holds secrets about you. Besides the names and numbers that you've programmed into it, traces of your DNA linger on the device, according to a new study.DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you- because you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims. Your cell phone can reveal more about you than you might think. Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. So she and colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs to collect invisible traces of the users from two parts of the phone:the outside, where the user holds it, and the speaker, which is placed at the user's ear.The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more.The scientists discovered DNA that belonged to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device. So cell phones can now be added to the ______ of clues that can clinch a crime scene investigation. 【单选题】A.explanationB.discoveryC.bookD.list正确答案:D答案解析:根据上下文的理解，应该选择list，其他三个选项与句子的意思不符。
2、Some Unusual CelebrationsSome holidays are well - known all around the world. Among them are New Year's Eve celebrations. Also common are days in honor of love and friendship, like Valentine's Day. Each country has its own special holidays too, often to mark important events in its history. Schools, banks and government offices all close on days like these. Some of the days people celebrate, however, are less serious. A few of them are really very strange. Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have longtraditions. Consider April Fool's Day, for example. No one knows when or why it began. Today it is celebrated in many countries—France, England and Australia, among others. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you? Dyngus Day in Poland seems strange too. On this day, it is traditional for boys to pour water over the heads of girls. Here is the strangest part, they do it to girls they like.Other unusual celebrations take place in a single city or town. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. Then begins the world-s biggest food fight. For two hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains and catch a wild goat. They bring him back to town, put a crown on his head, and make him king for three days.There are also some celebrations that are really strange. In theUnited States, sometimes one person gets an idea for a new holiday and tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 29. _____Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.【单选题】A.They bring him back to town, put a crown on his head, and make him king for three days.B.Some of the days people celebrate, however, are less serious.C.That is supposed to be Toothache Day.D.Then begins the world-s biggest food fight.E.Some people have fun imagining new holidays.。
