They continue to be among the best-known works of world literature. "The Ugly Duckling (小鸭)" and "The Little Mermaid (美人鱼)" are among the most famous.He was born on April 2,1805,in the slums of Odense,Denmark. His father was a shoemaker and his mother worked as a washer-woman. Andersen received very little education,but his fascination with fairy tales inspired him to compose his own stories and arrange puppet (木偶)shows.His father died when he was 11. He was forced to go to work,first as an apprentice to a weaver and tailor and then in a tobacco factory. At the age of 14,he moved to Copenhagen to try a career as a singer,dancer and actor. He sang in a boy's choir (合唱团),but he made very little money. He also tried the ballet,but his awkwardness made this impossible.Finally, when he was 17, Jonas Collin, a director of the Royal Theatre inCopenhagen discovered Andersen. After hearing Andersen read a play, Collin realized that he had talent. And he got money from the king for Andersen's education.In 1828, Andersen passed the entrance examinations to the university inCopenhagen. His writings were first published in 1829. In 1833,he received grant money for travel,which he used to visit Germany,France,Switzerland,and Italy. These journeys were recorded in his travelogues (旅行见闻)。

职称英语理工类A级考试真题及答案(部分)Small But WiseOn December 14, NASA1 blasted a small but mighty telescope into space. The telescope is called WISE and is about as wide around as a trashcan. Don’t let its small size fool you: WISE has a powerful digital camera, and it will be taking pictures of some the wildest objects2 in the known universe, including asteroids, faint stars, blazing galaxies3 and giant clouds of dust where planets and stars are born.“I’m very excited because we’re going to be s eeing parts of the universe that we haven’t seen before, “said Ned Wright, a scientist who directs the WISE project.Since arriving in space, the WISE telescope has been circling the Earth, held by gravity in a polar orbit4 (this means it crosses close to the north and south poles with each lap5). Its camera is pointed outward, away from the Earth, and WISE will snap a picture of a different part of the sky every 11 minutes. After six months it will have taken pictures across the entire sky.The pic tures taken by WISE won’t be like everyday digital photographs, however. WISE stands for “Wide-field Infrared Survey Explorer.” As its name suggests, the WISE camera takes pictures of features that give off infrared radiation6.Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of light7 that becomes visible in a rainbow, is an example of radiation. When an ordinary digital camera takes a picture of a tree, for example, it receives the wavesof visible light that are reflected off the tree. When these waves enter the camera through the lens, they’re processed by the camera, which then puts the image together.Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras don’t s ee them, and neither do the eyes of human beings. Although invisible to the eye, longer infrared radiation can be detected as warmth by the skin.That’s a key idea to why WISE will be able to see things other telescopes can’t. Not everything in the universe shows up in visible light. Asteroids, for example, are giant rocks that float through space — but they absorb most of the light that reaches them. They don’t reflect light, so they’re difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them. During its mission WISE will take pictures of hundreds of thousands of asteroids.Brown dwarfs8 are another kind of deep-space object that will show up in WISE’s pictures. These object s are “failed” stars — which means they are not massive enough to jump start9 the same kind of reactions that power stars such as the sun. Instead, brown dwarfs simply shrink and cool down. They’re so dim that they’re almost impossible to see with visible light, but in the infrared spectrum they glow.词汇:trashcan / ‘traelig;,kaelig;n/n.垃圾箱infrared/’infr’red/ adj.红外线asteroid/’aelig;strid/ n.小行星dwarf/dw:f/ n. 矮星注释:1.NASA (美国国家航空航天局)是缩写词,全称是National Aeronautics and Space Administration。

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。
职称英语《理工A》专项练习题及答案补全短文题篇一:Read with Greater SpeedDo you have difficulty reading in class? If so, a special reading program that helps match sounds with letters could speed up your brain.At least one out of every five elementary school students in the US has trouble learning to read, even when the students are good at other subjects.__________ (46) Researchers from Yale University, US, studied a group of children from New York and Connecticut State. As part of the study, 37 struggling readers received special tutoring.Every day, instructors worked with them on recognizing how written letters represent units of sound called phonemes (音素) .__________ (47)By the end of the school year, these children could read faster than before. They also made fewer mistakes, and understood more of what they read than they could earlier in the year.As part of their study, the researchers used a special machine to take action photos of the students' brains.__________(48) This is the same part of the brain that becomes active when good readers read, This activated brain area appears to include a structure that helps people recognize familiar written words quickly. In lower level readers, this structure remains inactive.A year later, the brain structure was still working hard in the students who had gone through the special tutoring, and they continued to do well in reading tests. __________ (49) However, some researchers still doubt the study.__________ (50)A. Many adults are interested in matching sounds with letters.B. The students also practiced reading aloud and spelling.C. The biggest challenge for many of these kids, scientists say, is matching sounds with letters.D. Another group in the study who went through a moretraditional reading program didn't show the same progress.E. The pictures showed all increase in activity in the back of the brain on the left side.F. They believe that reading without making any noise or linking words to sounds is more efficient.参考答案46.C。

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 foraround 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. Duringdreaming, these waves move more quickly. Breathing and pulse rate also increase,and there are rapid eye movements under the lids, just asthough 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 seldomwithout people in them and they are usually about people we know. One estimate says that two-thirds of the "cast" of our dream dramas arefriends and relations. Vision seems an essential part of dreams,except for people blind from birth. Sound and touch are senses also oftenaroused,but smell and taste are not frequently involved. In "normal" dreams,the dreamer may be taking part,or be only an observer. But heor 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 everyoneis a lucid dreamer. Some people are occasional lucid dreamers. Others can dream lucidly more or less all the time. In a 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.
