职称英语《理工A》概括大意历年真题及答案解析Black Holes(1) Black holes can be best described as a sort of vacuum, sucking up everything in space.Scientists have discovered that black holes come from an explosion of huge stars. Stars that are near death can no longer bum due to loss of fuel, and because its temperature can no longer control the gravitational (重力的 ) force, hydrogen ends up putting pressure onto the star's surface until it suddenly explodes then collapses.(2) Black holes come from stars that are made of hydrogen, other gases and a few metals. When these explode it can turn into a stellar-mass(恒星质量)black hole, which can only occur if the star is large enough (should be bigger than the sun) for the explosion to break it into pieces,and the gravity starts to compact every piece into the tiniest particle. Try to see and compare:if a star that's ten times the size of the sun end up being a black hole that's no longer than 70 kilometers, then the Earth would become black hole that's only a fraction of an inch!(3) Objects that get sucked in a black hole will always remain there, never to break free. But remember that black holes can only gobble up (吞噬) objects within a specific distance to it. It's possible for a large star near the sun to become a black hole, but the sun will continue to stay in place. Orbits (轨道) do not change because the newly formed black hole contains exactly the same amount of mass as when it was a star, only this its mass is totally contracted that it can end up as no bigger than a state.(4)So far, astronomers have figured out that black holes exist because of Albert Einstein's theory of relativity. In the end, through numerous studies, they have discovered that black holestruly exist. Since black holes trap light and do not give off light, it is not possible to detect black holes via a telescope. But astronomers continue to explore galaxies (银河系) , space and the solar system to understand how black holes. It is possible that black holes can exist for millions of years, and later contribute further process in galaxies, which can eventually lead to creation of new entities. Scientists also credit black holes as helpful in learning how galaxies began to form.23"~26概括大意23. Paragraph 1 __________24. Paragraph 2 __________25. Paragraph 3 __________26.

职称英语考试真题(理工类A级)Older V olcanic EruptionsV olcanoes 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 was investigat,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. He calculated 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 warming that followed wiped out 80 per cent of all manne genera at the 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 ones hardly hav e 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 becausemore 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 o f 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.。

Gorillas have a word for itKokois the first gorilla to have been taught sign language (a way of communicating by using hands and fingers rather than speech).With a vocabulary of more than1000 words, she is the first to prove we share a world with other intelligent beings who feel emotions, look forward to celebrations and also have a sense of humour.The 30-year study of Koko has redefined science’s concept of gorilla intelligence. 46 But what had not been recognized by thescientific community was that gorillas have the ability to learn a language and have complex emotions.Koko lives in the Santa Cruz mountains in North America,in a wooded spot overlooking a valley. 47 She has a barrel on which she likes to sit when 'talking' to humans - gorillas feel more secure when theycan look down on others - while her toys are spread everywhere. In addition she has an outside enclosure where she spends her days when it is not raining.It is her conversations with her teacher, Dr Penny Patterson,that are inspiring. Penny explains: ‘The reality of my discovery isthat our abilities as humans, our skills, sensibilities and emotions are very similar to the great apes. 48 .When she began teaching Koko sign language, placing the little fingers of the one-year-old gorilla into the correct positions for'drink', 'eaf, ’more、and rewarding her with food, Dr Patterson had no idea how quickly Koko would le arn. “At first, it seemed Koko was using sign language as a tool to get something,,,says Patterson. ’It became the kind of reward system that you could expect of a cat or a dog. But early in her training, she began to combine signs that made me think she w as capable of more.’ 49 For example, she didn't know the wordfor ’ring’,so she combined the signs for ‘finger’ and bracelet’ to express it.Dr Patterson continues: ‘Koko loves babies and young people. And when she is asked what gorillas like best, she always says "Gorilla love eat, good”? One of Patterson’s favourite stories demonstrates Koko's sense of humour. 50 .When Patterson asked her what she would like for her 11th birthday, Koko signed that she wanted a cat The story of Koko’s cat enabled Patterson to learn more about her student: the cat was hit by a car and Patterson had to break the news to Koko, who signed 'cry, sad, frown’. Then, once alone, Patterson heard Koko make the gorilla’s distress call: a loud series of hoots.From the age of three, Koko shared her accommodation with Michael who was intended as a mate.However, Michael died suddenly two years ago of a heart attack. cKoko went into a depression following Michael’s death,’ says Patterson. ‘She would sit for hours with her head hung low looking upset.'Dr Patterson asked her if she was looking forward to moving to Hawaii, where Patterson is raising money to build a gorilla refuge. Koko signed ‘Yes、provided she could have curtains in her new home!A.When a visitor asked her to show him something scary, she held up a mirror to his face!B.?C.According to some scientist, genetically there is only a 2% difference between gorillas and humans; we share the same blood type, have the same number of hairs per square inch and also the same temperament.D.She has her own home, with curtains, and a nest of blankets, which is her bed, in one comer.E.What we have learnt is that gorillas are more complex than we ever imaginedF.Now Koko is so proficient in sign language that if she doesn’t know a word she invents one.参考答案:第5部分:补全短文(第46——50题,每题2分,共10分) 46-50.

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 his father at an early age on the building of the Thames Tunnel. At the age of just twenty, he became engineer in charge of the 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)occurred in 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 rejected all 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 decidedto 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.A.RightB.WrongC.Not mentioned17.【题干】Brunel was involved less in railway construction than in other engineering fields.A.RightB.WrongC.Not mentioned18.【题干】Brunel worked only on shipping, bridge-building and railway construction.A.RightB.WrongC.Not mentioned19.【题干】Brunel work was largely ignored by his colleagues.A.RightB.WrongC.Not mentioned20.【题干】Some projects Brunel contributed to are still in use today.A.RightB.WrongC.Not mentioned21.【题干】Brunel became an apprentice with his father when he was very young.A.RightB.WrongC.Not mentioned22.【题干】The Thames Tunnel project was more difficult than any previous projects undertaken in Britain.A.RightB.WrongC.Not mentioned下载文档。
职称英语考试理工类(A级)真题及答案5第二篇Real-World RobotsWhen you think Of a robot,do you imagine a shiny ,metallic device having the same general shape as a human being,performing humanlike functions,and responding to your questions in a monotone(单调的)voice accentuated(强调)by high-pitched tones and beeps This is the way many of US imagine a robot,but in the real world a robot is not humanoid at all.instead,a robot often is a voiceless ,box- shaped machine that efficiently carries Out repetitive or dangerous functions usually performed by humans. Today” s robot is more than an automatic machine that performs one task again and again. A modern robot is programmed with varying degrees of artificial intelligence,that is,a robot contains a computer program that tells it how to perform tasks associated with human intelligence,such as reasoning,drawing conclusions,and learning from past.A robot does not possess a human shape for the simple reason that a two-legged robot has great difficulty remaining balanced.A robot does,however,move from place to place on wheels and axles(轮轴)that roll and rotate.A robot even has limbs that turn round and move in combination with joints and motors.To find its way in its surroundings, a robot utilizes various built -in sensors.Antennae attached to the robot’s base detect anything they bump into.If the robot starts to shake as it moves on an incline,a gyroscope(陀螺仪)inside it senses the vertical differential .TO determine Its distance from an object and how quickly it will reach the object,the robot bounces beams of laser. light and ultrasonic sound waves off obstructions(障碍物)in its path.These and other sensors constantly feed information to the computer,which thenanalyzes the information and corrects or adjusts the robot’s actions.As science and technology advance the robot too will progress in its functions and use of artificial intelligence programs.36 The writer begins the passage by comparingA.a real-life robot with a fictional robot.B.the shape of a human being with a box.C.an imaginary machine with a human.D.a robot with a computer program.37 The word “humanoid” in Paragraph 1 meanscking human feelings.考试大论坛cking human characteristics.C.having a human form and characteristicscking human intelligence.38 According to the first paragraph,artificial intelligence isA.the unnatural way in which robots move.B.a voiceless,box—shaped machine that performs repetitive tasksC.a computer program that imitates human intellectual processesD.a sensor that detects troubles in a robot.39 The last paragraph suggests that future robots willA.surpass human beings in intelligence.B.be more humanlike in behavior and action.e a laser to transmit information.D.will perform very complicated household jobs.40 Another good title for this passage would beA.Robots:Taking the Place of Humans.B.Artificial Intelligence Programs.C.Modern—Day Sensors.来源:考试大D.Today’S Robots and How They Function。
职称英语考试理工类(A级)试题及答案6第三篇Controlling Robots with the MindBelle,our tiny monkey,was seated in her special chair inside a chamber at our Duke University lab. Her right hand grasped a joystick (操纵杆)as she watched a horizontal series of lights on a display panel. She knew that if a light suddenly shone and she moved the joystick left or right to correspond to its position,she would be sent a drop of fruit juice into her mouth.Belle wore a cap glued to her head. Under it were four plastic connectors,which fed arrays of microwires-each wire finer than the finest sewing thread- into different regions of Belle’s motor cortex (脑皮层),tile brain tissue that plans movements and sends instructions. Each of the 100 microwires lay beside a single motor neuron (神经元)。
When a neuron produced an electrical discharge,the adjacent microwire would capture the current and send it up through a small wiring bundle that ran from Belle’s cap to a box of electronics on a table next to the booth. The box,in turn,was linked to two computers,one next door and the other half a country away.After months of hard work,we were about to test the idea that we could reliably translate the raw electrical activity in a living being’s brain-Belle’s mere thoughts-into signals that could direct the actions of a robot. We had assembled a multijointed robot arm in this room,away from Belle’s view,which she would control for the first time. As soon as Belle’s brain sensed a lit spot on the panel,electronics in the box running two real-time mathematical models would rapidly analyze the tiny action potentials produced by her brain cells. Our lab computer would convert the electrical patterns into instructions that would direct the robot arm. Sixhundred miles north,in Cambridge,Mass,a different computer would produce the same actions in another robot arm built by Mandayam A Srinivasan. If we had done everything correctly,the two robot arms would behave as Belle’s arm did,at exactly the same time.Finally the moment came. We randomly switched on lights in front of Belle,and she immediately moved her joystick back and forth to correspond to them. Our robot arm moved similarly to Belle’s real arm. So did Sriniwlsan’s. Belle and the robots moved in synchrony (同步),like dancers choreographed (设计舞蹈动作)by the electrical impulses sparking in Belle’s mind.In the two years since that day,our labs and several others have advanced neuroscience,computer science and microelectronics to create ways for rats,monkeys and eventually humans to control mechanical and electronic machines purely by “thinking through,” or imagining,the motions. Our immediate goal is to help a person who has been unable to move by a neurological (神经的)disorder or spinal cord (脊髓)injury,but whose motor codex is spared,to operate a wheelchair ora robotic limb.41 Belle would be fed some fruit juice if sheA.grasped the joystick.B.moved the joystick to the side of the light.C.sat quietly in a special chair.D.watched lights on a display panel.42 The wires fixed under Belle’s cap were connected toA.a plastic box next door.B.a computer at Cambridge University,C.a box of electronics in the booth.D.a box which,in turn,was linked to two computers43 Which of the following is NOT true of the robot built by Srinivasan?A.It was directed by signals converted from the electrical activity in Belle’s brainB.It converted the electrical patterns into instructions for the other robot.C.It was six hundred miles away from where Belle was.D.It could perform the same function as Belle did.44 Which of the following statements indicates the success of the experiment?A.Belle responded to the robots successfully.B.Belle and the robots danced beautifully.C.Belle and the robots responded to the lights at the same time.D.The two robots moved the joysticks successively.45 The short-term goal of the research is to help a personA.whose motor cortex is seriously damaged.B.who can operate a wheelchair but not a robotic limb.C.who has spinal cord injury but is able to move a wheelchair.D.who is unable to move but whose motor cortex is not damaged。

Lack of Oxygen Delayed the Rise of Animals on EarthScientists have long speculated as to why animal species didn’t flourish sooner, once sufficient oxygen covered the Earth’s surface. Animals began to prosper at the end of the Proterozoic period, about 800 million years ago — but what about the billion-year stretch before that, when most researchers think there also was plenty of oxygen?Well, it seems the air wasn’t so great then, after all.In a study published Oct. 31 in Science, Yale researcher Noah Planavsky and his colleagues found that oxygen levels during the “boring billion” period were only 0.1% of what they are today. In other words, Earth’s atmosphere couldn’t have supported a diversity of creatures, no matter what genetic advancements were poised to occur.“There is no question that genetic and ecological innovation must ultimately be behind the rise of animals, but it is equally unavoidable that animals need a certain level of oxygen,” said Planavsky, co-lead author of the research along with Christopher Reinhard of the Georgia Institute of Technology. “We’re providing the first evidence that oxygen levels were low enough during this period to potentially prevent the rise of animals.”The scientists found their evidence by analyzing chromium (Cr) isotopes in ancient sediments from China, Australia, Canada, and the United States. Chromium is found in the Earth’s continental crust, and chromium oxidation is directly linked to the presence of free oxygen in the atmosphere.Specifically, the team studied samples deposited in shallow, iron-rich ocean areas, near the shore. They compared their data with other samples taken from younger locales known to have higher levels of oxygen.Oxygen’s role in controlling the first appearance of animals has long vexed scientists. “We were missing the right approach until now,” Planavsky said. “Chromium gave us the proxy.” Previous estimates put the oxygen level at 40% of today’s conditions during pre-animal times, leaving open the possibility that oxygen was already plentiful enough to support animal life.In the new study, the researchers acknowledged that oxygen levels were “highly dynamic” in the early atmosphere, with the potential for occasional spikes. However,they said, “It seems clear that there is a first-order difference in the nature of Earth surface Cr cycling” before and after the rise of animals.“If we are right, our results will really change how people view the origins of animals and other complex life, and their relationships to the co-evolving environment,” said co-author Tim Lyons of the University of California-Riverside. “This could be a game changer.”“There’s a lot of interest right now in a broader discussion surrounding the role that environmental stability played in the evolution of complex life, and we think our results are a significant contribution to that,” Reinhard said.16.
