Experience the World in 3D GameEver wondered how your cat or dog sees the world? Now you can look through their eyes with the first 3D game that recreates the vision of different species based on scientific evidence.The online simulation, created by the French 3D design company Dassault Systèmes, with the guidance of veterinary ophthalmologist (眼科专家)Didier Schmidt-Morand, mimics (模仿)the vision of five animals –cats dogs, rats, hawks and bees – as a player steers them through Place Vendôme in Paris.Due to differences in field of view, colour perception and night vision, for example, sight can be drastically different from species to species. "In terms of performance, eyes are as variable as different models of cars," says Schmidt-Morand.The game was created by using existing virtual models of the square then applying effects based on descriptions of each animal's vision. Dassault's 3D software allows a scene to be modified by adding blur or changing the colours, angle of vision and depth of field.Although it was easy to recreate vision inferior to that of humans – cats and dogs, for example, have trouble distinguishing shades of red –replicating features that we are unable to see was a challenge. Hawks have more detailed vision than ours, whereas dogs are better at seeing movement and have a wider field of view. "We used virtual cameras to precisely simulate larger viewing angles but the result made people nauseous(令人作呕的)," says Schmidt-Morand. "So we tweaked(微调) the model to give a sense of the wider view without sticking to reality."The rat's view also departs from reality: because they are near-sighted, everything more than 15 centimetres away is a blur, so they typically move close to walls to help them navigate. "A rat would never throw itself into the middle of an open area," says Schmidt-Morand. The simulation for this animal is supplemented with a map in the top right corner to help determine the rat's position: because of their limited eyesight, most landmarks are obscured.2015年职称英语考试题库免费下载：/RhFad1WThe game is intended as an educational resource and players can discuss their experience with others through community features on thewebsite. If there is interest from schools and zoos, the team hopes to recreate the vision of more animals.16.The game developed by Dassault Systemes is the first 3D game recreating the vision of different species .A.RightB.WrongC.Not mentioned17.Dassault’s 3Dsoftware takes different perspe ctives like color perception and angle of vision into account .A.RightB.WrongC.Not mentioned18.The animals’views in the software are the same as those in reality .A.RightB.WrongC.Not mentioned19.Dogs have larger viewing angles than humans .A.RightB.WrongC.Not mentioned20.It takes the team the longest time to recreate the rat’s view because they’re near-sighted .A.RightB.WrongC.Not mentioned21.The team is working on recreating the vision of more animals .A.RightB.WrongC.Not mentioned22.Schmidt-Morand’s favorite animal is cat .A.RightB.WrongC.Not mentioned参考答案：AABACBC第3部分概括大意与完成句子23.

It is so hot and active that even the Sun’sgravity cannot hold its atmosphere in check! Energy flows away from the Suntoward the Earth in a stream of electrified particles that move at speedsaround a million miles per hour. These particles are called plasma, and thestream of plasma coming from the Sun is called the solar wind. The more activethe Sun, the stronger the solar wind.The solar wind constantly streams toward theEarth, but don’t worry because a protective magneticfields surrounds our planet. The same magnetic field that makes your compasspoint north also steers the particles from the Sun to the north and southpoles. The charged particles become trapped in magnetic belts around the Earth.When a large blast of solar wind crashes into the Earth’s magnetic field first gets squeezed and then the magnetic fieldlines break and reconnect.2015年职称英语考试题库免费下载：/RhFad1WThe breaking and reconnecting of the magneticfield lines can cause atomic particles called electrons trapped in the belts tofall into the Earth’s atmosphere at the poles. As theelectrons fall into the Earth, they collide with gas molecules in theatmosphere, creating flashes of light in the sky.Each atmospheric gas glows a different color.Oxygen and nitrogen glows red and green and nitrogen glows violet-purple. Asthese various colors glow and dance in the night sky, they create the NorthernLights and the Southern Lights.Watching auroras(北极光)is fun and exciting, but normally you can only see them in places far northlike Alaska and Canada. The movement of the aurora across the sky is usuallyslow enough to easily follow with your eyes but they can also pulsate(跳动), flicker(闪烁), or even move like waves.During solar maximum, 5 auroras are seen as far south as Florida, even Mexico!Aurorasoften seem to be very close to the ground, but the lowest aurora is still about100 kilometers above the ground, a distance much higher than clouds are formedor airplanes can fly. A typical aurora band can be thousands of kilometerslong, a few hundred kilometers high, but only a few hundred meters thick.We hope you are able to travel to far-northplaces like the Arctic Circle and see the Northern Lights at least once duringyour lifetime. We know you will never forget it!31. The solar wind comes into being as aresult of______A. disappearance of the Sun’s gravity.B. unpredictable weather of the Sun.C. fast flow of energy away from the Sun.D. a stream of particles being blown away.32. What happens when solar wind comes to theEarth?A. A protective magnetic field is formed atthe same time.B. It is trapped in magnetic belts around theEarth.C. It destroys the protective magnetic fieldsurrounding the Earth.D. It breaks magnetic field lines and doessevere damage to the ???33. The Northern Lights are createdwhen______A. atomic particles fall to the Earth and collidewith atmospheric gases.B. the magnetic field lines fail toreconnect.C. the electrons falling to the Earth shinein different colors.D. oxygen and nitrogen are separated from theatmospheric gases.34. Which of the following statements is trueof the Northern Lights?A. Their movement is slow enough to be observedwith the eyes.B. People cannot see them unless traveling toAlaska or CanadaC. They are very close to the ground.D. They are very long and thick.35. What is the author’s tone toward the Northern Lights?A. IndifferentB. SarcasticC. SharpD. Appreciative第二篇Eye-tracker Lots You Drag and Drop Files with a GlanceBored of using a mouse? Soon you'll be ableto change stuff on your computer screen – and then moveit directly onto your smartphone or tablet(平板电脑) –with nothing more than a glance.A system called EyeDrop uses a head-mountedeye tracker that simultaneously records your field of view so it knows whereyou are looking on the screen. Gazing at an object – aphoto, say – and then pressing a key, selects thatobject. It can then be moved from the screen to a tablet or smartphone just byglancing at the second device, as long as the two are connected wirelessly.2015年职称英语考试题库免费下载：/RhFad1W"The beauty of using gaze to supportthis is that our eyes naturally focus on content that we want to acquire,"says Jayson Turner, who developed the system with colleagues at LancasterUniversity, UK.Turner believes EyeDrop would be useful totransfer an interactive map or contact information from a public display toyour smartphone or for sharing photos.A button needs to be used to select theobject you are looking at otherwise you end up with the "Midastouch"(点石成金) effect, whereby everything you lookat gets selected by your gaze, says Turner. "Imagine if your mouse clickedon everything it pointed at," he says.Christian Holz, a researcher inhuman-computer interaction at Yahoo Labs in Sunnyvale, California, says thesystem is a nice take on getting round this fundamental problem of usinggaze-tracking to interact. "EyeDrop solves this in a slick (灵巧的)way by combining it with input on the touch devices we carry withus most of the time anyway and using touch input as a clutchingmechanism," he says. "This now allows users to seamlessly(无缝地) interact across devices far and close in a very naturalmanner."While current eye-trackers are rather bulky,mainstream consumer devices are not too far away. Swedish firm Tobii isdeveloping gaze-tracking technology that can be installed in laptops andtablets and is expected to be available to buy next year. And the Google Glassheadset is expected to include eye-tracking in the future.Turner says he has also looked at how contentcan be cut and pasted or drag-and-dropped using a mix of gaze and taps on atouchscreen. The system was presented at the Conference on Mobile andUbiquitous Multimedia in Sweden, last week.36. The eye-tracker technology enables usto______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.37. 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.38. The word “this” in Paragraph 6 refers to_______A. application of gaze-tracking inhuman-computer interaction.B. interaction between human and computer.C. combination of gaze-tracking with input ontouch devices.D. generalization of EyeDrop system.39. Which of the following statement is trueof eye-trackers for consumer devices.A. They are costly.B. They are available.C. They are installed in Google Glassheadset.D. They are expected to come out soon.40. 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 publicdisplay.第三篇2015年职称英语考试题库免费下载：/RhFad1WA New Strategy to Overcome Breast CancerPost-menopausal(绝经后)womenwho walk for an hour a day can cut their chance of breast cancer significantly,a study has suggested. The report , which followed 73,000 women for 17 years, foundwalking for at least seven hours a week lowered the risk of the disease. TheAmerican Cancer Society team said this was the first time reduced risk wasspecifically linked to walking. UK experts said it was more evidence thatlifestyle influenced cancer risk.A recent poll for the charity Ramblers aquarter of adults walk for no more than an hour a week, but being active isknown to reduce the risk of a number of cancers. This study, published inCancer Epidemiology, Biomarkers&Prevention, followed 73.615 women out of97,785 aged 50-74 who had been recruited by the American Cancer Society between1992 and 1993,so it could monitor the incidence of cancer in the group.They were asked to complete questionnaires ontheir health and on how much time they were active and participating inactivities such as walking, swimming and aerobics(有氧运动)andhow much time they spent sitting watching television or reading. They completedthe same questionnaires at two-year intervals between 1997 and 2009.Of thewomen,47% said walking was their only recreational acivity. Those who walkedfor at least seven hours per week had a 14% lower risk of breast cancercompared to those who walked three or fewer hours per week.Dr.Alpa Patel, a senior epidemiologist at theAmerican Cancer Society in Atlanta,Georgia,who led the study, said:”Given that more than 60% of women report some daily walking, promotingwalking as a healthyleisure-time activity could be an effective strategy forincreasing physical activity amongst post-menopausal women. We were pleased tofind that without any other recreational activity, just walking one hour a daywas associated with a lower risk of breast ca ncer in these women.””More strenuous(紧张的)and longer activitieslowered the risk even more.”Baroness Delyth Morgan, chief executive ofBreast Cancer Campaign, said:”This study adds furtherevidence that our lifestyle choices can play a part in influencing the risk ofbreast cancer and even small changes incorporate into our normal day-to-dayactivity can make a difference.”She added:”We knowthat the best weapon to overcoming breast cancer is the ability to stop itoccurring in the first place. The challenge now is how we turn thesefindings into action and identify othersustainable lifestyle changes that will help us prevent breast cancer.”41. All of the following factors relating tocancer risk were mentioned in the passage EXCEPT________A. breathing exerciseB. regular walkingC. recreational activityD. lifestyle choices42. It can be inferred from Dr. Alpa Patel’s study that____.A. women have fewer chances of physicalactivityB. daily walking could cut the chance of breastcancerC. leisure-time activity is not associatedwith cancer riskD. walking is not recommended for women withbreast cancer43. Dr. Alpa Patel was_____.A. head of the survey studyB. chief editor of Cancer EpidemiologyC. chair of the American Cancer SocietyD. chief executive of Breast Cancer Campaign44. Which of the following statements is trueaccording to the passage?A. Most women take walking as their onlyrecreational activity.B. The study aims to track the healthconditions of its subjects.C. Walking was the only recreationalacitivity for about half of the women2015年职称英语考试题库免费下载：/RhFad1WD. Irregular walking increased the risk ofbreast cancer inpost-menopausal women45. The word “sustainable”in the last paragraph is closest in meaning toA. continuableB. affordableC. availableD. persistent参考答案：CBAAD DDCDC ABAAA第5部分、补全短文WronglyConvicted Man and His Accuser Tell Their StoryNEW YORK,NY, January 5,2010. St.Martin’s Press has announced the release of the paperback edition ofPicking Cotton, a remarkable true story of what novelist John Grisham calls an “account of violence, rage, redemption(救赎)，and, ultimately forgiveness.”The story began in 1987, in Burlington, NorthCarolina, with the rape of a young while college student named JenniferThompson. During her ordeal, Thompson swore to herself that she would neverforget the face of her rapist, a man who climbed through the window of herapartment and assaulted her brutally.____F____(46)When the police asked her ifshe could identify the assilant(袭击者)from a book of mugshots, she picked one that she was sure was correct, and later she identifiedthe same man in a lineup.Based on her convincing eye withnesstestimony, a 22-year-old black man named Ronald Cotton was sentenced to prisonfor two life terms. Cotton’s lawyer appealed thedecision, and by the time of the appeals hearing, evidence had come to lightsuggesting that the real rapist might havebeen a man who looked very likeCotton, an imprisoned criminal named Bobby Poole.__B____(47)Jennifer Thompsonlooked at both men face to face, and once again said that Ronald Cotton was theone who raped her.Eleven years later, DNA evidence completelyexonerated(证明……清白)Cotton and just as unequivocally(明确地) convicted Poole, who confessed to the crime. _____E___(48) “The man I was so sure I had never seen in my life was the man whowas inches from my throat, who raped me, who hurt me, who took my spirit away,who robbed me of my soul,” she wrote. “And the man I had identified so surely on so many occasions wasabsolutely innocent.”____C___(49) Remarkably both were able to putthis tragedy behind them, overcome the racial barrier that divided them, andwrite a book, which they have subtit led “Our memoir ofinjustice and redemption.”Nevertheless, Thompson says, she still lives “with constant pain that my profound mistake cost him so dearly__A____(50)”A. Jennifer Thompson decided to meet Cottonand apologize to him personally.B. Many criminals are sent to prison on thebasis of accurate testimony by eye withnesses.C. I cannot begin to imagine what would havehappened had my mistaken identification occurred in a capital caseD. Another trial was held.E. Thompson was shocked and devastated.F. During the attack, she made an effort tomemorize eveery detail of his face, looking for scars, tattoos(纹身)，or other identifying marks.第6部分：完形填空(第51~65题，每题1分，共15分)下面的短文有15处空白，请根据短文内容为每处空白确定1个最佳选项。

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 stor's habitable zone. That's where the surface temperature would allow any water to exist as liquid.The new estimate of how many plantes 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.

Anyone hoping to pedal to work there has to contend with steep streets like Canton Avenue，which famouslyclimabs at a nearly 40-degree angle.As a result，some residents avoid biking altogether.2 But University of Pittsburgh graduate Micah Toll，23，and a few friends recently launched an invention that they hope will increase the city's pedal power. An electric bike called to Pulse PEVO. A super-strong battery powers the bicycle. Able to hit nearly 20 miles per hours without pedaling，it zips battery powers the bicycle. Able to hit nearly 20 miles per hour without pedating ，it zips up the city's most daunting(令人却步的)hills.Toll hopes it will persuade people in Pittsburgh and elsewhere to get out of their cars and onto bikes.3 If it sounds like Toll has a knack(窍门) for fixing problems，that's because he does. In high school，he designed a new type of construction beam. It weights no more than a feather pillow but can be used to build sturdy(坚固的)homes for refugees fleeing war or natural disaster.For his work，Toll was invited to attend the Inter International Science and Engineering Fair(Isef)—twice，in 2006 and 2007. The annual competition for young researchers is program of Society for Science&the Public(that's the parent organization of Science News for Kids).Toll says that when it comes to science，he keeps it simple：“You see a problem and say，“How couldI solve that?”4 He's not the only to take that approach. Many young researchers get their start by trying to solve a problem or fulfill a need in their own communities.When students dedicate themselves to finding a solution that many benefit theircommunity，“a passion is ignited(点燃)，”says Wendy Hawkins，executive director of the Inter Foundation，which sponsors Intel ISEF."Finding that passion and fostering it can be the key to many students future success."she says.23.

Each of us is different.Psychologists disagree about what is intelligence and what are talents or personal abilities .Psychologists have two different views on intelligence .Some believe there is one general intelligence .Others believe there are many different intelligences .Some psychologists say there is one type of intelligence that can be measured with IQ tests .These psychologists support their view with research that concludes that people who do well on one kind of test for mental ability do well on other tests .They do well on tests using words, numbers or pictures. They do well on individual or group tests, and written or oral tests .Those who do poorly on one test, do the same on all tests.Studies of the brain show that there is a biological basis for general intelligence .The brain of intelligence people use less energy during problem solving .The brain waves of people with higher intelligence show a quicker reaction .Some researchers conclude that differences in intelligence result from differences in the speed and effectiveness of information processing by the brain .Howard Gardner, a psychologist at the Harvard School of Education, has four children .He believes that all children are different and shouldn’t be tested by one intelligence test .Although Gardner believes general intelligence exists, he doesn’t think it tells much about the talents of a person outside of formal schooling .He think that the human mind has different intelligences .These intelligences allow us to solve the kinds of problems we are presented with in life .Each of us has different abilities within these intelligences .Gardner believes that the purpose of school should be to encourage development of all of our intelligences .Gardner says that his theory is based on biology .For example ,when one part of the Brain is injured ,other parts of the brain still work .People who cannot talkbecause of Brain damage can still sing .So ,there is not just one intelligence to lose .Gardner has Identified 8 different kinds of intelligence; linguistic, mathematical, spatial, musical, Interpersonal, intrapersonal, body-kinesthetic(身体动觉的),and naturalistic .31. What is the main idea of this passage?A. How to understand intelligence.B. The importance of intelligence.C. The development of intelligence tests.D. How to become intelligent.32. Which of the following statements is true concerning general intelligence?A. Most intelligent people do well on some intelligence tests.B. People doing well on one type of intelligence test do well on other tests.C. Intelligent people do not do well on group tests.D. Intelligent people do better on written tests than on oral tests.33. Gardner believes that ________.A. children have different intelligences.B. all children are alike.C. children should take one intelligence test.D. there is no general intelligence.34. According to Gardner, schools should ________.A. test students’IQs.B. train students who do poorly on tests.C. focus on finding the most intelligent students.D. promote development of all intelligences.35. Gardner thinks that his theory has a ________ .A. musical foundation.B. biological foundation.C. intrapersonal foundation.D. linguistic foundation.答案：ABADBMusic is one of the most beautiful forms of artistic expression是ever invented. In movies and plays，music has an added function：it not only moves people but also can shock people.Our eardrums can withstand sound within 20 to 80 decibels(分贝).Once sound exceeds this limit，even beautiful music will become ear-splitting noise and harm health.A strong blast(响声) of high sound can twist and break a solid iron sheet.High sound of 150 decibels can kill a healthy rat.In movies，sometimes the hero can produce a sound that ordinary people can't hear and only those who have the same ability can feel.In nature，there is actually sound that is beyond our hearing. In physics，the sound that exceeds 20000Hz is called ultrasonic(超音波的).Dolphins，whales and bats can make suchhigh-frequency sound.It does no harm to health.Sound less than 20Hz is called infrasonic(次声)waves. When we move，the air will vibrate. The vibration of air can produce infrasonic wave.As the frequency of infrasonic waves is close to that of people's internal organs，infrasonic wave may cause resonance(共振) in human bodies. As a result，people's vision may weaken and internal organs may rupture(断裂). However，whether an infrasonic wave can be used as a weapon depends on its intensity. If its intensity is very low，it won't damage internal organs or a person's health. If the intensity of inf让sonic wave exceeds 160 decibels，it is extremely harmful. When wind blows at a force of 3 or 4 over the sea，it will produce infrasonic waves of several decibels. Only typhoons canproduce infrasonic waves of over 100 decibels. At present，scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.36 What could be the best title of the passage?A The power of musicB The harms of noisesC The magic of soundD The discovery of infrasonic waves37 What does the author say about music?A It may be harmful to people's halthB It always cheers people upC It is very often difficult to understandD It sounds better when it is lound enough38 It is true that the soundA of nature is the most beautifulB over 80 decibels is harmful to peopleC of high intensity benefits animalsD in movies is pleasing to the ear39 An ultrasonic soundA is very loudB does harm to people's healthC cannot be heard by peopleD is produced by the hero in movies40 It can be found from the last paragraph that infrasonic wavesA are harmless to people's healthB exist in people's internal organsC can be used as deadly weaponsD can improve eyesight答案：CABCCCompact DisksIf someone says to you your music CDs don't really hold any music on them, and they only have numbers recorded on them, you may not believe it. In fact, he isright in that sound is actually recorded onto the CDs as special numbers —a digital code.1 The code is pressed onto the CD as bumps on a long spiral track almost five kilometers long. These bumps are an average of 0.5 microns wide.A small laser beam shines onto the bumps as the CD turns. The light is reflected back to a receiver that records how the laser light bounces back. This lets the CD player2 turn the reflected light back into the original code. This means you can hear the original code as music.Digital codes are used with many technologies. E-mail needs these kinds of code numbers. Space probes communicate with their ground station on earth using digital codes. Bar codes are read as digital codes in computer systems. Digital communications with cell phones need digital codes. Weather radios also tune into specific signals using these codes.There are many types of compact disks. One format is called CD-RWs. They can be recorded on and re-recorded on(rewritten on)as you would do with a floppy disk3. Another format is the CD-ROM. The technology for recording on these disks is different from other CDs. These CDs have a dye layer that the CD writer can darken or leave clear. The clear and dark spots are the digital code. CD-ROM stands for Compact Disc —Read Only Memory4. This disk is like a "super" floppy disk that can hold lots of information. One CD-ROM can hold the same amount of data as 500 floppy disks. Information is permanently recorded onto it. Computer games and other programs are considered to be CD-ROMs.CDs were first sold to the public in 1982 These CDs still play well and sound fine. Current CDs are expected to last between 70 to 200 years. Of course, you can make sure your CDs last a long time by taking care of them.Science keeps on developing. It may not be many more years before a completely new technology is invented5 and introduced to the public for music recording. In the meantime, there is no doubt you will continue to enjoy listening to your favorite music on CDs6 and playing your favorite computer games onCD-ROMs.41 Music is recorded onto CDs asA laser beamsB digital codesC musical notesD special sounds42 E-mail is mentioned in the third paragraph to showA the variety of digital communicationsB the development of new technologiesC the usefulness of digital codesD the relationship between communication and technology43 One of the differences between CD-RWs and CD-ROMs isA CD-ROMs can be used for longer timeB CD-ROMs cannot be rewritten onC CD-RWs hold more informationD CD-RWs are merely used for music recording44 CDs can last a long time ifA they are seldom usedB they play well and sound fineC their users take good care of themD they are developed with new technology45 It can be inferred from the passage thatA CD-ROMs are more expensive than other CDsB new technology for music recording is being developedC the author likes listening to musicD flppy disks are no longer in use答案：BCBCC第5部分，补全短文Do You Have a Sense of Humor?Humor and laughter are good for us. There is increasing evidence that they can heal us physically，mentally，emotionally，and spiritually. In fact，every system of the body responds to laughter in some positive，healing way. So how can we get more laughter into our lives?(46)Psychologist and author，Steve Wlison，has some answers.Many peoplebelieve that we are born with a sense of humor.They think，“either you've got it，or you don't”Dr.Wilson points out that this false.(47) The parts of brain and central nervous system that control laughing and smiling are mature at birth(48)(After all ，when a baby laughs，we don't rush over and say，“That kid has a great sense of humor!”)A sense of humor is something that you can develop over a lifetime.Sometimes people think that they don't have a good sense of humor because they are not good joke tellers.Dr.Wilson reminds us that telling jokes is only one of many ways to express humor.(49)Then we will make others laugh，too.A person who has a true sense of humor is willing and able to see the funny side of everyday life.One of the best definition of a sense of humor is“the ability to see the nonserious element in a situation.”Consider this sign from a sore window.“Any faulty merchandise will be cheerfully replanced with merchandise of equal quality.”The store manager probably placed the sign in the window to impress customers with the store's excellent service.(50)As Dr.Wilson says，“a good sense of humor means that you don't have to be funny;you just have to see what's funny.”A He advises us to lose our inhibitions(抑制)and try to laugh at ourselves.B Is it possible to develop a sense of humor?C However，that does not mean that infants have a sense of humor.D What is true，however，it that we are born with the capacity to laugh and smileE Everyone experiences this emotionF He had a serious purpose，but if you have a sense of humor，you will probably find the sign funny!答案：BDCAF第6部分：完形填空(第51~65题，每题1分，共15分)Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle1 events —flowering, the appearance of leaves, the first frog calls of the spring —all around the world. But ecologists can't be everywhere so they're turning to non-scientists, sometimes called citizen scientists, for help.Climate scientists are not present everywhere. Because there are so many places in the world and not enough scientists to observe all of them, they're asking for your help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people to observe a very specific research interest —birds, trees, flowers budding, etc. —and send their observations to a giant database to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat2, citizen scientists are ready for the conditions where they live. All that's needed to become one is a few minutes each day or each week to gather data and send it in.A group of scientists and educators launched an organization last year called the National Phenology4Network. “Phenology”is what scientists call the study of the timing of events in nature.One of the group's first efforts relies on scientists and non-scientists alike to collect data about plant flowering and leafing every year. The program, called Project Bud Burst, collects life cycle data on a variety of common plants from acrossthe United States. People participating in the project —which is open to everyone —record their observations on the Project Bud Burst website.“People don't have to be plant experts —they just have to look around and see what's in their neighborhood,”says Jennifer Schwartz, an education consultant with the project. “As we collect this data, we'll be able to make an estimate of how plants and communities of plants and animals will respond as the climate changes.”51 A everywhere B anywhere C somewhere D nowher52 A If B Although C When D Because53 A giving B showing C developing D observing54 A special B professional C skillful D ordinary55 A on B at C to D with56 A small B limited C smple D large57 A Very B Much C AsD Many58 A All B Any C Some D Most59 A send B print C answer D keep60 A known B featured C belonged D called61 A alike B like C unlike D likely62 A points B wonders C data D interests63 A common B suitable C open D strange64 A want B forget C mind D have65 A who B how C before D since ADDDC BDAAD ACCDB。

职称英语等级理工类(A级)试题考试试题答案及题解4第二篇A Phone That Knows You’re BusyIt’s a modern problem：you’re too busy to be disturbed by incessant(连续不断的)phone calls so you turn your cellphone off .But if you don’t remember to turn it back on when you’re less busy．you could miss some important calls if only the phone knew when it was wise to interrupt you，you wouldn’t have to turn it off at all. Instead，it could let calls through when you are not too busyA bunch of behavior sensors(传感器)and a clever piece of software could do just that，by analyzing your behavior to determine if it’s a good time to interrupt you．If built into a phone，the system may decide you’re too busy and ask the caller to leave a message or ring back later．James Fogarty and Scott Hudson at Camegie Mellon University in Pennsylvania based their system oil tiny microphones，cameras and touch sensors that reveal body language and activity．First they had to study different behaviors to find out which ones stongly predict whether your mind is interrupted.The potential“busyness”signals they focused on included whether the office doors were left open or closed，the time of day，if other people were with the person in question，how close they were to each other, and whether or not the computer was in use．The sensors monitored these and many other factors while four subjects were at work . At random intervals，the subjects rated how interruptible they were on a scale ranging from“highly interruptible’’to“highly not—interruptible” . Their ratin gs were then correlated with the various behaviors . “It is a shotgun(随意的)approach：we used all the indicators we could think of and then let statistics find out which wereimportant，” says Hudson.The model showed that using the keyboard，and talking on a landline or to someone else in the office correlated most strongly with how interruptible the subjects judged themselves to be．Interestingly，the computer was actually better than people at predicting when someone was too busy to be interrupted . The computer got it right 82 per cent of the time，humans 77 per cent．Fogarty speculates that this might be because people doing the interrupting are inevitably biased towards delivering their message，whereas computers don’t care．The first application for Hudson and Fogarty’s system is likely to be in an instant messaging system，followed by office phones and cellphones．“There is no technological roadblock(障碍) to it being deployed in a couple of years，” says Hudson36 A big problem facing people today is thatA they must tolerate phone disturbances or miss important calls．B they must turn off their phones to keep their homes quiet．C they have to switch from a desktop phone to a cellphone．D they are too busy to make phone calls．37 The behavior sensor and software system built in a phoneA could help store messages．B could send messages instantlyC could tell when it is wise to interrupt you．D could identify important phone calls．38 Scientists at Carnegie Menon University tried to find outA why office doors were often 1eft open．B when it was a good time to turn off the computer．C what questions office workers were bothered with．D which behaviors could tell whether a person was busy39 During the experiment，the subjects were askedA to control the sensors and the camera．B to rate the degrees to which they could be interrupted．C to compare their behaviors with others’.D to analyze all the indicators of interruption．40 The computer performed better than people in the study becauseA the computer worked harder．B the computer was not busyC people tended to be biased．D people were not good at statistics．。

2013年度全国职称英语等级考试理工类(A级)试题(二)
2013年度全国职称英语等级考试理工类（A级）试题第4部分：阅读理解（第31~45题，每题3分，共45分）下面有3篇短文，每篇短文后有5道题。
请根据短文内容，为每题确定1个最佳选项。
第一篇On the Trail of the Honey BadgerOn a recent field trip to the Kalahari Desert, a team of researchers learnt a lot more about honey badgers (獾)The team employed a local wildlife expert, Kitso Khama, to help them locate and follow the badgers across the desert. Their main aim was to study the badgers’ movements and behaviour as discreetly (谨慎地）as possible, without frightening them away or causing them to change their natural behaviour. They also planned to trap a few and study them close up before relea sing them. In view of the anima’s reputation, this was something that even Khama was reluctant to do.“The problem with honey badgers Is they are naturally curious animals, especially when they see something new,”he says. “That，combined with their unpredictable nature, can be a dangerous mixture. If they sense you have food, for example, they won’t be shy about coming right up to you for something to eat. They’re actually quite sociable creatures around humans, but as soon as they feel they might be in danger, they can become extremely vicious (凶恶的) Fortunately this is rare, but it does happen. ’’The research confirmed many things that were already known. As expected, honey badgers ate any creatures they could catch and kill. Even poisonous snakes, feared and avoided by most other animals, were not safe from them. The researchers were surprised, however, by the animal’s fondness for local melons, probably because of their high water content. Previously researchers thought that the animal got ail of its liquid requirements from its prey (猎物). The team also learnt that, contrary to previous research findings, the badgers occasionally formed loose family groups. They were also able to confirm certain results from previous research, including the fact that female badgers never socialised with each other.Following some of the male badgers was a challenge, since they can cover large distances in a short space of time. Some hunting territories cover more than 500 square kilometres. Although they seem happy to share these territories with other males, there are occasional fights over an Important food source, and male badgers can be as aggressive towards each other as they are towards other species.As the badgers became accustomed to the presence of people，it gave the team the chance to get up close to them without being the subject of the animals，curiosity —or their sudden aggression. The badgers’ eating patterns, which had been disrupted, returned to normal. It also allowed the team to observe more closely some of the other creatures that form working associations with the honey badger, as these seemed to adopt the badgers’ relaxed attitude when near humans.28 Why did the wildlife experts visit the Kalahari Desert?A To find where honey badgers live.B To observe how honey badgers behave.C To catch some honey badgers for food.D To find out why honey badgers have a bad reputation.29 What does Kitso Khama say about honey badgers?A They show interest in things they are not familiar with.B They are always looking for food.C They do not enjoy human company.D it is common for them to attack people.30 What did the team find out about honey badgers?A There were some creatures they did not eat.B They were afraid of poisonous creatures.C They may get some of the water they needed from fruit.D Female badgers did not mix with male badgers.31 Which of the following is a typical feature of male badgers?A They don't run very quickly.B They hunt over a very large area.C They defend their territory from other badgers.D They are more aggressive than females.32 What happened when honey badgers got used to humans around them?A They lost interest in people.B They became less aggressive towards other creatures.C They started eating more.D Other animals started working with them.第二篇Forecasting MethodsThere are several different methods that can be used to create a forecast. The method a forecaster chooses depends upon the experience of the forecaster, the amount of information available to the forecaster, the level of difficulty that the forecast situation presents, and the degree of accuracy or confidence needed in the forecast.The first of these methods is the persistence method; the simplest way of producing a forecast. The persistence method assumes that the conditions at the time of the forecast will not change. For example, if it is sunny and 87 degrees today, the persistence method predicts that it will be sunny and 87 degrees tomorrow, if two inches of rain fell today, the persistence method would predict two inches of rain for tomorrow. However, if weather conditions change significantly from day to day, the persistence method usually breaks down and is not the best forecasting method to use.The trends method involves determining the speed and direction of movement for fronts, high and low pressure centers, and areas of clouds and precipitation (降水量) Using this information, the forecaster can predict where he or she expects those features to be at some future time. For example, if a storm system is 1,000 miles west of your location and moving to the east at 250 miles per day, using the trends method you would predict it to arrive in your area in 4 days. The trends method works well when systems continue to move at the same speed in the same direction for a long period of time. If they slow down, speed up, change intensity, or change directions, the trends forecast will probably not work as well.The climatology (气候学）method is another simple way of producing a forecast. This method involves averaging weather statistics accumulated over many years to make the forecast. For example, if you were using the climatology method to predict the weather for New York City on July 4th, you would go through all the weather data that has been recorded for every July 4th and take an average. The climatology method only works well when the weather pattern is similar to that expected for the chosen time of year. If the pattern is quite unusual for the given time of year, the climatology method will often fall.The analog method is a slightly more complicated method of producing a forecast. It involves examining today’s forecast scenario (模式）and remembering a day in the past when the weather scenario looked very similar (an analog). The forecaster would predict that the weather in this forecast will behave the same as it did in the past. The analog method is difficult to use because It isvirtually impossible to find a predict analog. Various weather features rarely align themselves in the same locations as they were in the previous time. Even small differences between the current time and the analog can lead to very different results.36 Which of the following factors is NOT mentioned in choosing a forecasting method?A Necessary amount of information.B Creativity of the forecaster.C Degree of difficulty involved in forecasting.D Practical knowledge of the forecaster.37 The persistence method fails to work well whenA it is rainy.B it is sunny.C weather conditions stay stable.D weather conditions change greatly.38 The trends method works well whenA weather features are constant for a long period of time.B weather features are defined well enough.C predictions on precipitation are accurate.D the speed and direction of movement are predicable.39 The analog method should not be used in making a weather forecast whenA the analog looks complicated.B the analog is more than 10 years old.C the current weather scenario is different from the analog.D the current weather scenario is exactly the same as the analog.40 Historical weather data are necessary inA the persistence method and the trends method.B the trends method and the climatology method.C the climatology method and the analog method.D the persistence method and the analog method.第三篇Students Learn Better with Touchscreen DesksObserve the criticisms of nearly any major public education system in the world, and a few of the many complaints are more or less universal. Technology moves faster than the education system. Teachers must teach at the pace of the slowest student rather than the fastest. And - particularly in the United States - school children as a group don’t care much for, or excel（擅长）at, mathematics. So it's heartening to l earn that a new kind of “classroom of the future” shows promise at easing some of these problems, starting with that fundamental piece of classroom furniture: the desk.AUK study involving roughly 400 students, mostly aged 8-10 years, and a new generation of multi-touch, multi-user, computerized desktop surfaces is showing that over the last three years the technology has appreciably boosted students ’ math skills compare d with peers learning the same material via the conventional paper-and-pencil method. How? Through collaboration，mostly, as well as by giving teachers better tools by which to micromanage individual students who need some extra Instruction while allowing the rest of the class to continue moving forward.Traditional instruction still shows respectable efficacy (效力）at increasing students’ fluency in mathematics, essentially through memorization and practice - dull, repetitive practice. But the researchers have concluded that these new touchscreen desks boost both fluency and flexibility - the critical thinking skills that allow students to solve complex problems not simply through knowing formulas and devices，but by being able to figure out what the real problem is and the most effective means of stripping it down and solving It.One reason for this, the researchers say, is the multi-touch aspect of the technology. Students working in the next-gen classroom can work together at the same tabletop, each of them contributing and engaging with the problem as part of a group. Known as SynergyNet, the software uses computervision systems that see in the infrared (红外线的）spectrum to distinguish between different touches on different parts of the surface, allowing students to access and use tools on the screen, move objects and visual aids around on their desktops, and otherwise physically interact with the numbers and information on their screens. By using these screens collaboratively, the researchers say, the students are to some extent teaching themselves as those with a stronger grasp on difficult concepts pull other students forward along with them.41 Which of the following statements is NOT true of the public education system?A It does not catch up with the development of technology.B Some similar complaints about It are heard in different countries.C Teachers pay more attention to fast learners than slow learners.D Many students are not good at learning mathematics.42 What has been found after the new tech is employed?A Students become less active in learning mathematics.B Teachers are able to give individualized attention to students in need.C Students show preference to the conventional paper-and-pencil method.D The gap between slow learners and fast learners gets more noticeable.43 What is the benefit students get from the new tech?A It makes them more fluent in public speech.B It offers them more flexibility in choosing courses.C It Is effective in helping them solve physical problems.D It enables them to develop critical thinking ability.44 What happens when students are using the desktop of the new tech?A Every student has an individual tabletop.B The multi-touch function stimulates students.C The software installed automatically identifies different users.D Students use different tools to interact with each other.45 How does the new tech work to improve students, mathematical learning?A It enables them to work together.B It helps fast learners to learn faster.C It makes teachers’ instruction unnecessary.D It allows the whole class to learn at the same pace.。

In a discovery that sounds more like an ancient Chinese proverb than a materials science breakthrough, MIT researchers have discovered that silk gets its strength from its weakness. Or, more specifically, its many weaknesses. Silk gets its extraordinary durability and ductility (柔韧性) from an unusual arrangement of hydrogen bonds that are intrinsically very weak but that work together to create a strong, flexible structure.Most materials —especially the ones we engineer for strength —get their toughness from brittleness. As such, natural silks like those produced by spiders have long fascinated both biologists and engineers because of their light weight, ductility and high strength (pound for pound, silk is stronger than steel and far less brittle). But on its face, it doesn't seem that silks should be as strong as they are; molecularly, they are held together by hydrogen bonds, which are far weaker than the covalent (共价的) bonds found in othermolecules.To get a better understanding of how silk manages to produce such strength through such weak bonds, the MIT team created a set of computer models that allowed them to observe the way silk behaves at the atomic level. They found that the arrangement of the tiny silk nanocrystals (纳米晶体) is such that the hydrogen bonds are able to work cooperatively, reinforcing one another against external forces and failing slowly when they do fail, so as not so allow a sudden fracture to spread across a silk structure.The result is natural silks that can stretch and bend while retaining a high degree of strength. But while that's all well and good for spiders, bees and the like, this understanding of silk geometry could lead to new materials that are stronger and more ductile than those we can currently manufacture. Our best and strongest materials are generally expensive and difficult to produce (requiring high temperature treatments or energy-intensive processes).By looking to silk as a model, researchers could potentially devise new manufacturing methods that rely on inexpensive materials and weak bonds to create less rigid, moreforgiving materials that are nonetheless stronger than anything currently on offer. And if you thought you were going to get out of this materials science story without hearing about carbon nanotubes (纳米碳管), think again. The MIT team is already in the lab looking into ways of synthesizing silk-like structures out of materials that are stronger than natural silk — like carbon nanotubes. Super-silks are on the horizon.16. MIT researchers carry out the study to illustrate an ancient Chinese proverb.A. RightB. WrongC. Not mentioned17. Silk’s strength comes from its weak hydrogen bonds working together.A. RightB. WrongC. Not mentioned18.

Toads are Arthritic and in PainArthritis (关节炎）is an Illness that can cause pain and swelling in your bones. Toads (蟾蜍），a big problem In the north of Australia, are suffering from painful arthritis in their legs and backbone, a new study has shown. The toads that jump the fastest are more likely to be larger and to have longer legs.___ (46)The large yellow toads, native to South and Central America, were introduced into the north-eastern Australian state of Queensland in 1935 In an attempt to stop beetles and other Insects from destroying sugarcane crops. Now up to 200 million of the poisonous toads exist in the country, and they are rapidly spreading through the state of Northern Territory at a rate of up to 60 km a year. The toads can now be found across more than one million square kilometres. ___ (47) A Venezuelan poison virus was tried in the 1990s but had to be abandoned after it was found to also kill native frog species.The toads have severely affected ecosystems in Australia. Animals, and sometimes pets, that eat the toads die immediately from their poison, and the toads themselves eat anything they can fit inside their mouth. ___ (48)A co-author of the new study, Rick Shine, a professor at the University of Sydney, says that little attention has been given to the problems that toads face. Rick and his colleagues studied nearly 500 toads from Queensland and the Northern Territory and found that those in the latter state were very different. They were active, sprinting down roads and breeding quickly.According to the results of the study, the fastest toads travel nearly one kilometer a night. ___ (49) But speed and strength come at a price — arthritis of the legs and backbone due to constant pressure placed on them.In laboratory tests, the researchers found that after about 15 minutes of hopping, arthritic toads would travel less distance with each hop (跳跃）. ___ (50) These toads are so programmed to move, apparently, that even when in pain the toads travelled as fast and as far as the healthy ones, continuing their constant march across the landscape.A Furthermore, they soon take over the natural habitats of Australia’s native species.B Toads are not built to be road runners — they are built to sit around ponds and wet areas.C But this advantage also has a big drawback — up to 10% of the biggest toads suffer from arthritis.D But arthritis didn’t slow down toads outside the laboratory, the researchers found.E The task now facing the country is how to remove the toads.F Toads with longer legs move faster and travel longer distances, while the others are being left behind.第6部分：完形填空（第51 ~65题，每题1分，共I5分）下面的短文有15处空白，请根据短文内容为每处空白确定1个最佳选项。
