2020年职称英语考试真题(理工类A级) Older Volcanic EruptionsVolcanoes were more destructive in ancient history, not because they were bigger, but becausethe carbon dioxide they released wiped out life with greater ease.Paul Wignall from the University of Leeds wasinvestigat,ing the link between volcaniceruptions and mass extinctions. Not all volcanic eruptions killed- off large numbers of animals, butall the mass extinctions over the past 300 million years coincided with huge formations of volcanicrock. To his surprise, the older the massive volcanic eruptions were, the more.damage they seemedto do. Hecalculated the "killing efficiency" for these volcanoes by comparing the proportion of lifethey killed off with the volume of lava that they produced. He found that size for size, oldereruptions were at least 10 times as effective at wiping out life as their more recent rivals.The Permian extinction' ,for example, which happened 250 million years ago, is marked byfloods of volcanic rock in Siberia that cover an area roughly the size of western Europe. Thosevolcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide. Theglobal warmingthat followed wiped out 80 per cent of all manne genera atthe time, and it took 5million years for the planet to recover. Yet 60 million years ago, there was another huge amount ofvolcanic activity and global warming but no mass extinction. Some animals did disappear but thingsreturned to normal within ten thousands of years. "The most recent oneshardly have an effect atall.”Wignall says. He ignored the extinction which wiped out the dinosaurs 65 million years ago,because many scientists believe it was primarily caused by the impact of an asteroid. He thinks thatolder volcanoes had more killing power because more recent life forms were better adapted todealing with increased levels of C02.Vincent Courtillot, director of the Paris Geophysical Institute in France, says that Wignall'sidea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points outthat the killing power of volcanic eruptions depends on how long they lasted. And it is impossible totell whether the huge blasts lasted for thousands or millions of years. He also adds that it is difficultto estimate how much lava prehistoric volcanoes produced, and that lava volume may notnecessarily correspond to carbon dioxide emissions.。

2020年职称英语理工A阅读判断真题及答案

2020年职称英语理工A阅读判断真题及答案阅读判断The Greatest of Victorian EngineersIn the hundred years up to 1860, the work of a smallgroup of construction engineers carried forward the enormous social and economic change that we associate with theIndustrial Revolution in Britain. The most important of these engineers was Isambard Kingdom Brunel, whose work in shipping, bridge-building, and railway construction, to name just three fields, both challenged and motivated his colleagues. He was the driving force behind a number of the hugely ambitious projects, some of which resulted in works which are still in use today.The son of an engineer, Brunel apprenticed with hisfather at an early age on the building of the Thames Tunnel.At the age of just twenty, he became engineer in charge ofthe project. This impressive plan to bore under the Thames twice suffered two major disasters when the river broke through into the tunnel when the second breach(决口)occurredin 1872, Brunel was seriously injured during rescue operation and further work was halted.While recovering from his injuries, Brunel entered a design competition for a new bridge over the Avon Gorge near Clifton. The original judge of the competition was Thomas Telford, a leading civil engineer of his day, who rejectedall entries to the competition in favor of his own design. After considerable scandal, a second contest was held and Brunel's design was accepted. For reasons of funding, however,exacerbated(加剧) by social unrest in Bristol, the project was abandoned in 1843 with only the towers completed. After Brunel’s death, it was decided to begin work on it again, partly so that the bridge could form a fitting memorial to the great engineer. The entire structure was finally completed in 1864. Today, the well-known Clifton Suspension Bridge is a symbol of Bristol, just as the Opera House is of Sydney. Originally intended only for horse-drawn traffic, the bridge now bears over four million motor vehicles a year.16.【题干】Brunel was an important airplane engineer in Britain during the Industrial Revolution.【选项】A.RightB.WrongC.Not mentioned【答案】C【解析】17.【题干】Brunel was involved less in railway construction than in other engineering fields.【选项】A.RightB.WrongC.Not mentioned【答案】C【解析】18.【题干】Brunel worked only on shipping, bridge-building and railway construction.【选项】A.RightB.WrongC.Not mentioned【答案】B【解析】19.【题干】Brunel work was largely ignored by his colleagues.【选项】A.RightB.WrongC.Not mentioned【答案】B【解析】20.【题干】Some projects Brunel contributed to are still in use today.【选项】A.RightB.Wrong。

Although the explosionobliterates the star，it saves some of the star‘s matterfrom being devoured by the black hole.The explosion ispowerful enough to hurl mu ch of the star’s matter out of the black hole‘s reach，he says.The devouring of stars by black holes may already have been observed，although at a much later stage.It is thought that several months after the event that rips the star apart，its matter starts swirling into the hole itself.It heats upas it does so，releasing ultraviolet light and X-rays.If stars disrupted near black holes really do explode，then they could in principle allow these events to bedetected at a much earlier stage，says Jules Hatpern of Columbia University in New York，US2.“It may make it。

2020年职称英语理工类A级考试阅读理解练习题(3) The Exploding Lakes of CameroonWhat comes to mind when you think of a lake? You probably imagine a pretty scene withblue water，birds，and fish.For the people in the northwestern Cameroon，however, the image isvery different. For them，lakes may mean terrible disasters. In 1984，poisonous gases explodedout of Lake Monoun and came down into the nearby villages，killing thirty―seven people.Twoyears later,Lake Nyos erupted A cloud of gases rolleddown the hills and into the valleys andkilled 1,700 people.Lake Nyos and Lake Monoun are crater(火山口)lakes They were formed when watercollected in the craters of old volcanoes The volcanoes under Lake Nyos and Lake Monoun arenot active anymore. However, poisonous gases from the center of the earth continue to flow upthrough cracks in the bottom of the lake. This is normalin a crater lake. In most crater lakes，thesegases are released often because the water‘turnsover’regularly.That is，the water from thebottom of the lake rises and mixes with the water at the top，allowing the gases to escape slowly.However，in Lakes Nyos and Monoun，there is no regular turning over.No one knows thereason for this fact，but as a result，these lakes have more gases tapped at the bottom than othercrater lakes. In fact，scientists who have studied Lakes Nyos and Monoun have found 16,000times more gases.When a strong wind，cool weather a storm，or a landslide(滑坡)causes thewater to turn over suddenly，the gases escape in aviolent explosion.In the past，no one knew when the gases might explode，so there was no way for the villagersto escape disaster. Now scientists from the United States，France，and Cameroon have found away to reduce the gas pressure at the bottom of Lake Nyos.They stood a 672-foot plastic pipe inthe middle of the lake，with one end of the pipe near the bottom and the other end in the air.Nearthe top of the pipe，the team put several holes thatcould be opened or closed by a computer.Now，when the gas pressure gets too high，the holes are opened and some of the gas-filled water shootsup through the pipe into the air like a fountain.With less pressure，a disastrous explosion is muchless likely.However, the scientists are not sure that one pipe will be enough to prevent explosions.They hope to put in others soon and they plan to install a similar pipe and a computer system at Lake Monoun as well.To protect people nearby until all of the pipes are in place.the scientists have installed earlywarning systems at both lakes. If the gas pressure rises to a dangerous level，computers will setoff loud sirens(警报)and bright lights to warn the people in the villages.That way, they willhave time to escape from the dangerous gases.41 What will happen when Lake Nyos and Lake Monoun explode?A Water will flow down the hillsB Poisonous gases will be released suddenly.C A strong wind will rise from the lakesD The volcanoes will come to life.42 Which of the following statements about Lake Nyos and Lake Monoun is true?A They were formed in 1984.B They are at the top of two active volcanoes.C They are not like most other crater lakes.。

2020年职称英语理工A阅读理解真题及答案

2020年职称英语理工A阅读理解真题及答案Sports Star Yao MingIf Yao Ming is not the biggest sports star in the world, he is almost certainly the tallest. At 2.26m, he is the tallest player in the National Basketball Association (NBA) and holds the record as the most towering Olympian ever to compete in the Games.But what really stands out about the giant center is his celebrity(名气). Few, if any, Chinese athletes are as well-known as Yao around the world. People across the globe are fascinated with Yao, not only for his basketball prowess(杰出的才能)also for being a symbol of international commerce.When Yao joined the Houston Rockets as the No.1 pick in the 2002 NBA draft(选抜)， he was the first international player ever to be selected first. His assets on the court are clear enough—no NBA player of his size has ever possessed his mobility, so he is a handful(难对付的人)for opponents on either end of the court. But what makes Yao invaluable to the Rockets organization is his role as a global citizen and as a bridge to millions of potential basketball fans in China.When it was announced in February that Yao would miss the rest of the NBA season and possibly the Olympics with a stress fracture(骨折)in his left foot, a collectiveshudder(震动)spread across China. After considerable debate and discussion, Yao opted to get his foot surgically treated in an operation that placed several tiny screws across the bone, to offer his overburdened foot more support. The surgery was a success, and though the estimated four-monthrecovery period will leave him little time to prepare with Team China, Yao has vowed to be ready for the Beijing Olympics.Yao wrapped up a 10-day trip to China, where he underwent a series of traditional Chinese medicine (TCM) treatments, hoping to accelerate his recovery process Western experts are generally skeptical of TCM's benefits although new research from the University of Rochester suggests that a certain compound derived from shellfish may indeed stimulate bone repair."There is no reason to dismiss TCM," Yao told a press conference in Beijing." It's been used in our country for thousands of years. I don't think that it's short on science."31.【题干】The word "towering" in Paragraph 1 means_____【选项】rge.B.fat.C.tall.D.great.【答案】C【解析】32.【题干】Opponents find it very difficult to control Yao Ming because of his_____【选项】A.mobility.B.assault.C.defense.D.celebrity.【答案】A【解析】33.【题干】Yao Ming had to undergo a series of TCM treatments because_____【选项】A.his right foot had been hurting.B.he wanted to make a more rapid recovery.C.the surgical operation had been a failure.D.he couldn't afford all the medical expenses.【答案】B【解析】34.【题干】Which statement about Yao Ming is NOT true?【选项】A.He missed the Athens Olympics.B.He is an NBA player.C.He fractured his left foot.D.He is an international figure.。

2020年职称英语考试真题理工类A级阅读理解(文字版)Older Volcanic EruptionsVolcanoes were more destructive in ancient history, not because they were bigger, but because the carbon dioxide they released wiped out life with greater ease.Paul Wignall from the University of Leeds wasinvestigating the link between volcanic eruptions and mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over thepast 300 million years coincided with huge formations of volcanic rock. To his surprise, the older the massivevolcanic eruptions were, the more damage they seemed to do.He calculated the "killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.The Permian extinction, for example, which happened 250 million years ago, is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe. Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide. The global warmingthat followed wiped out 80 per cent of all marine genera atthe time, and it took 5 million years for the planet to recover. Yet 60 million years ago, there was another huge amount of volcanic activity and global warming but no massextinction. Some animals did disappear but things returned to normal within ten thousands of years. "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs 65 million years ago, because many scientists believe it was primarily caused bythe impact of an asteroid. He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2.Vincent Courtillot, director of the Paris Geophysical. Institute in France, says that Wignall’s idea is prov ocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power ofvolcanic eruptions depends on how long they lasted. And it is impossible to tell whether the huge blasts lasted for thousands or millions of years. He also adds that it isdifficult to estimate how much lava prehistoric volcanoes produced, and that lava volume may not necessarily correspond to carbon dioxide emissions.Black Holes TriggerScientists have long understood that supermassive black holes weighing millions or billions of suns can tear apart stars that come too close.The black hotels gravity pullsharder on the nearest part of the star，an imbalance thatpulls the star apart over a period of minutes or hours，onceit gets close enough.Scientists say this Uneven pulling is not the only hazard facing the star.The strain of these unbalanced forces canalso trigger a nuclear explosion powerful enough to destroythe star from within.Matthieu Brassart and Jean-PierreLuminet of the Observatoire de Paris in Meudon，France1，carried out computer simulations of the final moments of such an unfortunate star‘s life，as it veered towards a supermassive black hole.When the star gets close enough，the uneven forcesflatten it into a pancake shape.Some previous studies had suggested this flattening would increase the density and temperature inside the star enough to trigger intense nuclear reactions that would tear it apart.But other studies had suggested that the picture would be complicated by shockwaves generated during the flattening process and that no nuclear explosion should occur.The new simulations investigated the effects of shock waves in detail，and found that even when their effects are included，the conditions favor a nuclear explo sion.“Therewill be an explosion of the star — it will be completely destroyed，” Brassart says. Although the explosionobliterates the star，it saves some of the star‘s matterfrom being devoured by the black hole.The explosion ispowerful enough to hurl mu ch of the star’s matter out of the black hole‘s reach，he says.The devouring of stars by black holes may already have been observed，although at a much later stage.It is thought that several months after the event that rips the star apart，its matter starts swirling into the hole itself.It heats upas it does so，releasing ultraviolet light and X-rays.If stars disrupted near black holes really do explode，then they could in principle allow these events to bedetected at a much earlier stage，says Jules Hatpern ofColumbia University in New York，US2.“It may make itpossible to see the disruption of that star immediately if it gets hot enough，” he says.Brassart agrees.“Perhaps it can be observed in the X-rays and gamma rays，but it‘s something that needs to bemore studied，” he says.Supernova researcher Chris Fryer of the Los Alamos National Laboratory in Los Alamos，New Mexico，US3，says the deaths of these stars are difficult to simulate，and he is not sure whether the researchers have proven their case that they explode in the process.词汇：supermassive adj.特大质量的imbalance/im5bAlEns/n.不平衡，不平衡veer/ viE/v.转向，改变方向flatten/5flAtn/v.使成扁平，夷平pancake/5pAnkeik/n.薄煎饼obliterate/E5blitEreit/v.抹去，除去，消除devour/di5vauE（r）/v.吞没；毁灭swirl/swE：l/打旋，旋动gamma rays γ 射线supernova/7sju：pE5nEuvE/n.超新星。

2020年职称英语理工类A级阅读理解第二篇考试真题及答案

2020年职称英语理工类A级阅读理解第二篇考试真题及答案阅读理解第二篇 Deforestation and Desertification(沙漠化）TheSahel zone lies between the Saharadesert and thefertile savannahs(热带大草原）ofnorthern Nigeria and South Sudan. The word sahel comes from Arabic and means marginal or transitional ,andthis is a good description of thesesemi-arid(半干旱）lands,whichoccupy much of the Western African countries of Mail,Mauritania,Niger,and Chad.Unfortunately, over the last century theSahara desert has steadily crept southwards eating into once productive Sahellands. United Nations surveys show that over 70 percent of the dry land inagriculture use in Africa has deterioratedover the last 30 years. Droughts have become more severe, the most recentlasting over twenty years in parts of the Sahel region. The same process ofdesertification istaking place across southern Africa as the Kalahari desertadvances into Botswana and parts of South Africa.One ofthe major causes of this desert advance ispoor agricultural land use, driven by the pressures of increasing population.Overgrazing一 keeping too many farm animals on the land一means that grasses and other plants cannot recover, and scarce water suppliesare exhausted. Overcultivation一tryingto grow too many crops on poor land一 resultsin thesoil becoming even less fertile and drier, and beginning tobreak up. Soilerosion (侵蚀) follows, and the land turns into desert.Another cause of desertification is loss of tree cover. Trees are cutdown for use as fuel and to clear land for agricultural use. Tree roots help tobind the soil together, to conserve moisture, and to provide a habitat forother plants and animals. When trees are cut down, the soil begins to dry andloosen, wind and rain erosion increase, other plant species die, and eventuallythe fertile top soil may be almost entirely lost, leaving only bare rock anddust.The effects of loss of topsoil and increased drought are irreversible. Theyare,however, preventable. Careful conservation of tree cover and sustainableagricultural land use have been shown to halt deterioration of soils and lessenthe effects of shortage of rainfall. One project in Kita in south-west Malifunded by UNDP has involved local communities in sustainable management offorest,while at the same time providing a viable(有活力的）agriculturaleconomy. This may be a model for similar projects in otherWest African countries.35 order to prevent desertification,the author proposes ___.A. making good use of international aidsB. developing a sustainableagricultural economyC. gaining international supportD. converting agricultural land intoforest答案：b36．The Sahel zone is an area which ___.A. is covered with sad and grassB. has a long historyC. occupies much of South NigeriaD. belongs to Sudan答案：a37. What is the situation about thedesertification in Africa?A. The deserts are replaced withgrasslandsB. The deserts are expandingC. the deserts are moving northwardsD. the deserts are being deserted答案：b38. The word “deteriorated ” in paragraph2 means ___.A. deepenedB. sufferedC. slippedD. worsened答案：d39. What is the root causeof desertification?A. poor farming。

2020年职称英语考试理工类A级练习题：阅读判断(3)

2020年职称英语考试理工类A级练习题：阅读判断(3)A Dolphin and an AstronomerOne 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.
