It may also play animportant role inlove. But what is music, and how does it work its magic Science does not yet have all theanswers.What are two things that make humans different from animals One is language,and the other is music. It is true that some animals can sing ( and many birdssing .better than a lot of people). However,the songs of animals, such as birds and whales, are very limited. It is also true that humans, not animals ,have developed musical instruments.Music is strange stuff. It is clearly different from language. However, people can use music to communicate things -- especially their emotions. When music is combined with speech in a song, it is a very powerful form of communication. But, biologically speaking, what is musicIf music is truly different from speech, then we should process music and language in different parts of the brain. The scientific evidence suggests thatthis is true.Sometimes people who suffer brain damage lose their ability to process language. However, they don't automatically lose their musical abilities. For example, Vissarion Shebalin, a Russiancomposer, had a stroke in 1953. It injured the left side of his brain. He could no longer speak orunderstand speech. He could, however, still compose music until his death ten years later. On theother hand, sometimes strokes cause people to lose their musical ability, but they can still speak and understand speech. This shows that the brain processes music and language separately.By studying the physical effects of music on the body, scientists have also learned a lot about how music influences the emotions. But why does music have such a strong effect on us That is a harder question to answer. Geoffrey Miller, a researcher at University College, London, thinks that music and love have a strong connection. Music requires special tale ent, practice, and physical ability. That's why it may bea way of showing your fitness to be someone'. For example, singing in tune or playing a musical instrument requires fine muscular control. You also need a good memory to remember the notes. And playing or singing those notes correctly suggests that your hearing is in excellent condition.Finally ,when a man sings to the woman he loves (or vice versa), it may be a way of showing off.However ,Miller's theory still doesn't explain why certain combinations of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research.注释：1．It is also true that humans，not animals，have developed musical instruments：人研制出了乐器，而动物则不能。
develop：研制，例如：Scientists are developing new drugs to treat cancer．科学家们正在研发新药用以治疗癌症。
练习：1. Humans,but not animals, can sing.A RightB WrongC Not mentioned2. People can use music to communicate their emotions.A RightB WrongC Not mentioned.3. We use the same part of the brain for music and language.A RightB WrongC Not mentioned4. Geoffery Miler has done research on music and emotions.A RightB WrongC Not mentioned5. It's hard for humans to compose music.A RightB WrongC Not mentioned6. Memory is not an important part in singing in tune.A RightB WrongC Not mentioned7. Scientists does not know all the answers about the effects of music on humans.A RightB WrongC Not mentioned答案与题解：1．B 第二段的第三句：It is true that some animals can sing(and many birds sing better than a lot of people)．可以看出有些动物会唱歌，而不只人类会唱歌。
2．A第三段的第三句：However，people can use music to communicate things—especially theiremotions．这句清楚表明，人们可以用音乐来表达情感。
3．B第四段说明：科学证明人们用大脑的不同区域处理语言和音乐。
在第五段，作者用Vissarion Shebalin的例子进一步说明人脑处理语言和音乐的位置不同，Shebalin中风以后不能讲话也听不懂别人的话，但他却能创作乐曲。
4．A 第六段的第四句：Geoffrey Miller，a researcher at University College，London，thinks thatmusic and love have a strong connection．这句说明Miller对音乐和爱(情感)的关系进行了研究，他得出的结论是：音乐和爱有密切的关联。
5．C文中没有提及创作乐曲是否困难。
6．B第六段有一句：You also need a good memory to remember the notes．此句说明必须具备好的记忆力记音符才能唱得符合调子。
7．A最后一段讲的是：科学家们需要做更多的研究才能解释为什么有些声音影响我们的情感会如此之深。
也就是说，科学家不能全部解释音乐对人类的影响。
译文：音乐生物学人们把音乐作为一种高效的交流方式，在爱情中它也可能会起到重要的作用。
但是音乐是什么它又是如何起到神奇的效果科学界还没有给出答案。
哪两项事物使得人类不同于动物一个是语言，另一个是音乐。
当然一些动物会唱歌 (并且许多鸟唱得比很多人都好听) ，但是，动物的歌声是有限的，比如鸟类和鲸鱼。
同样，是人类而不是动物开发出了乐器。
音乐是个奇怪的东西，它与语言有明显的不同。
但是，人们能够用音乐去传达——尤其是情感。
当音乐与歌曲中的语言结合在一起的时候，它就是一种强有力的表达方式。

The Russian Mir Space Station, which came down in 2001 at last after 15 years of pioneering the concept of long-term human space flight, is remembered for its accomplishments in the human space flight history. It can be credited with many firsts in space.During Mir's lifetime, Russia spent about US$4.2 billion to build and maintain the station.The Soviet Union launched Mir, which was designed to last from three to five years, on February 20, 1986, and housed 104 astronauts over 12 years and seven months, most of whom were not Russian. In fact, it became the first international space station by playing host to 62 people from 11 countries. From 1995 through 1998, seven astronauts from the United States took turns living on Mir for up to six months each. They were among the 37 Americans who visited the station during nine stopovers by space shuttles.The more than 400 million the United States provided Russian for the visits not only kept Mir operating, but also gave the Americans and their partners in the international station project valuable experience in long-term flight and multinational operations.A debate continues over Mir’s contributions to science.During its existence, Mir was the laboratory for 23,000 experiments and carried scientific equipment, estimated to be worth $80 million, from many nations. Experiments on Mir are credited with a range of findings, from the first solid measurement of the ration of heavy helium atoms in space to how to grow wheat in space. But for those favouring human space exploration, Mir showed that people could live and work in space long enough for a trip to Mars. The longest single stay in space is the 437. 7 days that Russian astronaut Valery Polyakov spent on Mir from 1994 to 1995. And Sergie Avdeyev accumulated 747.6 days in space in three trips to the space station. The longest American stay was that of Shannon Lucid, who spent 188 days aboard Mir in 1996.Despite the many firsts Mir accomplished, 1997 was a bad year out of 15 for Mir. In 1997, an oxygen generator caught fire. Later, the main computer system broke down, causing the station to drift several times and there were power failures.Most of these problems were repaired, with American help and suppliers, but Mir's reputation as a space station was ruined.Mir’s setbacks are nothing, though, when we compare them with its accomplishments. Mire was a tremendous success, which will be remembered as a milestone in space exploration and the space station that showed long-term human habitation in space was possible. But it's time to move on to the next generation. The International Space Station being built will be better, but it owes a great debt to Mir.31. What can we learn from the passage that the Mir Space StationA. was designed to last 5 years.B. was built by Russians.C. played nost to 7 astronauts from different countries.D. was visited only by Americans.32. One of the contributions Mir makes to science is that itA. helps astronauts get close to Mars.B. enables scientists to develop new scientific equipment.C. sets a record of the longest single human stay in space.D. shows that multinational operations in space are less expensive.33. What happened to Mir in 1997?A. It ran out of its fund.B. It was completely damage by fire.C. Its main computer system broke down.D. Its reputation was ruined due to power failures.34. It can be inferred from the last paragraph thatA. space exploration will not experience setbacks.B. it is difficult for other space stations to exceed Mir’s success.C. Mir is the best long-term human habitation in space in history.D. multinational space operations are getting more accomplishments.35.What is the author’s attitude toward Mir?A. Favorable.B. Indifferent.C. Ironic.D. Negative.参考答案：31. A. was designed to last 5 years.32. C. sets a record of the longest single human stay in space.33. C. Its main computer system broke down.34. D. multinational space operations are getting more accomplishments.35. A. Favorable.【2017职称英语理工类B级阅读理解练习题】。

职称英语真题理工类B级试题阅读理解及答案
职称英语真题理工类B级试题阅读理解及答案Eye-tracker Lots You Drag and Drop Files with a GlanceBored of using a mouse? Soon you'll be able to change stuff on your computer screen – and then move it directly onto your smartphone or tablet(平板电脑) –with nothing more than a glance.A system called EyeDrop uses a head-mounted eye tracker that simultaneously records your field of view so it knows where you are looking on the screen. Gazing at an object – a photo, say – and then pressing a key, selects that object. It can then be moved from the screen to a tablet or smartphone just by glancing at the second device, as long as the two are connected wirelessly."The beauty of using gaze to support this is that our eyes naturally focus on content that we want to acquire, "says Jayson Turner, who developed the system with colleagues at Lancaster University, UK.Turner believes EyeDrop would be useful to transfer an interactive map or contact information from a public display to your smartphone or for sharing photos.A button needs to be used to select the object you are looking at otherwise you end up with the "Midas touch"(点石成金) effect, whereby everything you look at gets selected by your gaze, says Turner. "Imagine if your mouse clicked on everything it pointed at," he says.Christian Holz, a researcher in human-computer interaction at Yahoo Labs in Sunnyvale, California, says the system is a nice take on getting round this fundamental problem of using gaze-tracking to interact. "EyeDrop solves this in a slick (灵巧的)way by combining it with input on the touch devices we carry with us most of the time anyway and using touch input as a clutching mechanism," he says. "This now allows users to seamlessly(无缝地) interact across devices far and close in a very natural manner."While current eye-trackers are rather bulky, mainstream consumer devices are not too far away. Swedish firm Tobii is developing gaze-tracking technology that can be installed in laptops and tablets and isexpected to be available to buy next year. And the Google Glass headset is expected to include eye-tracking in the future.Turner says he has also looked at how content can be cut and pasted or drag-and-dropped using a mix of gaze and taps on a touch screen. The system was presented at the Conference on Mobile and Ubiquitous Multimedia in Sweden, last week.31. The eye-tracker technology enables us to______A. change our computer screen.B. focus on anything that interests us.C. get a smartphone connected wirelessly.D. move an object from screen with a glance.32. Why is a button needed?A. To minimize the cost of EyeDrop.B. To choose as many objects as possible.C. To make EyeDrop different from others.D. To select what we want.33. The word “this” in Paragraph 6 refers to_______A. application of gaze-tracking in human-computer interaction.B. interaction between human and computer.C. combination of gaze-tracking with input on touch devices.D. generalization of EyeDrop system.34. Which of the following statement is true of eye-trackers for consumer devices.A. They are costly.B. They are available.C. They are installed in Google Glass headset.D. They are expected to come out soon.35. What is Turner likely to study next?A. How to drag and drop with gaze and taps.B. How to present the system in public.C. How to get touch screen involved.D. How to cut and paste content from a public display. 答案：DDCDC。

It draws on data that came from NASA's top planet-hunting telescope. A mechanical failure recently put that Kepter space telescope out of service. Kepler had played a big role in creating a census of planets orbiting some 170,000 stars. Its date have been helping astronomers predict how common planets are in our galaxy. The telescope focused on hunting planets that might have conditions similar to those on Earth. The authors of a study published in The Proceedings of the National Academy of Sciences conclude that between 14 and 30 out of every 100 stars with a mass and temperature similar to the Sun may host a planet that could support life as we know it. Such a planet would have a diameter at least as large as Earth's but no more than twice that big. The planet also would have to orbit in a star's habitable zone. That's where the surface temperature would allow any water to exist as liquid. The new estimate of how many planets might fit these conditions comes from studying more that 42,000 stars and identifying suitable worlds orbiting them. The scientists used those numbers to extrapolate (推算) to the rest of the stars that the telescope could not see. The estimate is rough, the authors admit. If applied to the solar system, it would define as habitable a zone starting as close ot the Sun as Venus and running to as far away as Mars. Neither planet is Earthlike (although either might have been in the distant pase). Using tighter limits the researchers estimate the between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world. These are ones that would take 200 to 400 days to complete a yearly orbit. Four out of every 100 sunlike stars doesn't sound like a big number. It would mean however that the Milky Way could host more than a billion Earth-sized planets with a chance for life. 16. The Kepler space telescope has been in service for 15 years. A. Right B.

These researchers tinker (修补) with machines in the lab and write computer software to control these devices. "They're the best toys out there,"says Howle Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist, a person who designs, builds or programs robots. When Choset was a kid, he was interested in anything that moved---cars, trains, animals. He put motors on Tinkertoy cars to make them move. Later, in high school, he built mobile robots similar to small cars. Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena, Choset's labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist (扭曲) in many directions and travel over a lot of different types of terrain (地形) . "Snakes are far more interesting than the cars, "Choset concluded. After he started working at Carnegie Mellon, Choset and his colleagues there bagan developing their own snake robots. Choset's team programmed robots to perform the same movements as real snakes, such as sliding and inching forward. The robots also moved in ways that snakes usually don't, such as rolling. Choset's snake robots could crawl (爬⾏) through the grass, swim in a pond and even climb a flagpole. But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient's chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake? Choset teamed up with Marco Zenati, a heart surgeon now at Harvard Medical School, to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs. A company called Medrobotics in Boston is now adapting the technology to surgeries on people. Even after 15 years of working with his team's creations, "I still don't get bored of watching the motion of my robots," Choset says. 16. Choset began to build robots in high school. A. Right B. Wrong C. Not mentioned 17. Snake robots could move in only four directions. A. Right B. Wrong C. Not mentioned 18. Choset didn't begin developing his own snake robots until he started working at CamegieMellon. A. Right B. Wrong C. Not mentioned 19. Choset's snake robots could make more movements than the ones others developed. A. Right B. Wrong C. Not mentioned 20. The application of a thin robotic snake makes heart surgeries less time-consuming. A. Right B. Wrong C. Not mentioned 21. Zenati tested the robot on people after using it in pigs. A. Right B. Wrong C. Not mentioned 22. The robotic technology for surgeries on people has brought a handsome profit to Medrobotics. A. Right B. Wrong C. Not mentioned 答案与解析 2015年真题 16．B。

If their noses inhaled(吸入)a certain type of air pollution when they were pregnant. That's the finding of a new study. Released when things aren't burned pletely, this pollution is known as polycyclic aromatic hydrocarbons, or PAHs. The biggest sources of these PAHs: the burning of fossil fuels, wood and trash.Frederica Perera works at Columbia University's Mailman School of Public Health is New York City. She researches how exposure to things in the environment affectschildren's health in a new study, she and her team studied the exposure to air pollution of 233 nonsmoking pregnant women in New York City. Because burning tobao can spew(排放)PAHs into the air and lungs, Perera's team focused on nonsmokers. The researchers wanted to probe(探查)other sources of PAHs, ones that's would have been hard for an individual to avoid.The team started by testing the blood of each woman during pregnancy. The reason Any PAHs in a woman's blood would also be available to the baby in her womb. Nine years later, the researchers investigated signs of attention problems in those children, now age 9. They asked eachchild's mother a series of questions. These included whatever her child had problems doing things that needed sustained(长期的)mental effort, such as homework or games with friends. The scientists also asked if the kids had trouble following instructions or made frequent, careless mistakes. All of these can be symptoms of a disorder called Attention Deficit Hyperactivity Disorder, or ADHD. About one in U.S. children has ADHD.Among the women studied, traffic and home heating were the primary sources of air pollution exposure, Perera andher team suspect. Some of these women had low levels of PAHs in their blood. Ohters had high levels. Those with high levels were five times as likely to have children who showed attention problems by age 9. The new findings were published November 5 in the journal PLOS ONE.16. Perera and her team chose nonsmoking pregnant women all over America.A. RightB. WrongC. Not mentioned17. The main purpose of the research was to find out how exposure to PAHs played a role in harming the subjects' physical health.A. RightB. WrongC. Not mentioned18.
