职称英语考试《理工类》历年真题精选及答案0513-81、Cell Phone Lets Your Secret OutYour cell phone holds secrets about you. Besides the names and numbers that you've programmed into it, traces of your DNA linger on the device, according to a new study.DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you-because you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims. Your cell phone can reveal more about you than you might think. Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. ______ she and colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs tocollect invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user's ear.The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more.The scientists discovered DNA that belonged to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device. So cell phones can now be added to the list of clues that can clinch a crime scene investigation.【单选题】A.HoweverB.SoC.ButD.Nevertheless正确答案:B答案解析:四个选项中只有B是正确选择，连接了其前后两个句子，使其形成因果关系：她思考微量DNA是否会停留在手机上，所以，她与同事们一起对10名志愿者的翻盖手机进行了分析研究。

第十一篇When our Eyes Serve our StomachOur senses aren't just delivering a strict view of what's going on in the world;they're affectedby what's going on in otir heads, A new study finds that hungry people see food-related words more clearly than people who've just eaten.Psychologists have known for decades that what's going on,inside our head affects our senses. For example,poorer cliildren think coins are larger than they are, and hungry people think pictures of food are brighter, Remi Radel of University of Nice Sopbia-Antipolis, France, wanted to investigate how this happens. Does it happen right away as the brain receives signals from the eyes or a little later as the brain's high-level thinking processes get involved.Radel recruited 42 students with a normal body mass index.On the day of his or her rest,each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes;others were given an hour to get lunch first.So half the students were hungry when they did the experiment and the other half had just eaten.For the experiment,the participant looked at a computer screen. One by one ,80 words flashedon the screen for about 1/300th of a second each. They flashed at so small a size that the students could only consciously perceive. A quarter of the words were food-related. After each word , eachperson was asked how bright the word was and asked to choose which of two words they'd seen -a food-related word like cake or a neutral word like boat. Each word appeared too briefly for the participant to really read it.Hungry people saw the food-related words as brighter and were better at identifying food-related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception not in thinking processes,Radel says."This is something great to me, Humans can really perceive what they need or what they strive for. From the experiment,1 know that our brain can really be at the disposal of 6 our motives and needs , " Radel says.词汇：threshold n. 起点，开端；门槛disposal n. 处理，处置：配置neutral adj.中性的；中立的motive n. 动机，目的strive v. 努力.力求：斗争注释：1.Our senses aren't just delivering a strict view of …in our heads ：这个句子的大概意思是：我们的五官感觉不仅仅让我们感知世界；五官感觉还受大脑活动的影响。

2013年度全国职称英语等级考试理工类(C级)试题及参考答案
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. RightB. WrongC.

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 other molecules.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, more forgiving 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.
