第六篇Eat to LiveA meager diet may give you health and long life, but it, s not much fun-and it might not even be necessary. We may be able to hang on to1most of that youthful vigor even if we don't start to diet until old age.Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins2.Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations3. Three more mice were switched from the normal diet to half-feed3, for a month when they were 34 months old -- equivalent to about 70 human years.The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production4- probably bad news for mouse health. In the mice that had dieted all their lives,27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of these gene changes."This is the first indication that these effects kick in5 pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C.No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says.If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective.But Spindler isn't sure the trade-off is worth it6"The mice get less disease, they live longer,but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'."Spindler hopes we' soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction.词汇：meager／♊mi:♈☯/adj.不足的vigor／♊v✋♈☯/n.精力，活力genetic/d✞☯♊net✋k/adj.基因的rejuvenation/❒✋♊d✞u:v☯♊ne✋☞☯n/n.恢复活力，返老还童toxin/♊t ks✋⏹/n.毒素inflammation/ ✋⏹fl☯♊me✋☞☯n/n.炎症，发炎rejuvenate/r✋♊d✞u v☯ne✋t/vt.使恢复活力youthful／♊ju f☯l/adj.有青春活力的metabolize/m☯♊t✌b☯la✋z/vt.使（一种物质）进入新陈代谢过程liver/♊●✋☯/n.肝脏ration/♊r✌☞☯n/n.定量calorie/♊k✌l☯ri/n.卡（热量的单位）trade-off／♊tre✋d f/n.交换，交易注释：1． hang on to:继续保留。

第十九篇Graphene's SuperstrengthBig technology comes in tiny packages. New cell phones and personal computers get smallerevery year，which means these electronics require even smaller components on the inside.Engineers are looking for creative ways to build these components，and they've turned their eyes to graphene，a superthin2 material，made of carbon，that could change the future of electronics.This year's Nobel Prize for Physics3 has been awarded to Andre Geim and Kostya Novoselovfrom the University of Manchester4，UK. for the discovery of graphene. Graphene isn't just small,it's“the thinnest possible material in this world，” says Novoselov. He calls it a“wondermaterial. ”It's so thin that you would need to stack about 25,000 sheets just to make a pile as thick as a piece of ordinary white paper. If you were to hold a sheet of graphene in your fingers5，you'd have no idea because you wouldn't be able to see it. Carbon is one of the most abundant elements in the universe. Every known kind of lifecontains carbon. Graphene is a sheet of carbon，but only one atom thick. You don't have to lookfar to find grapheme —it's all around you.If you want this high-tech wonderstuff6，all you need is a pencil，paper and a little adhesivetape. Use the pencil to shade a small area on the paper, and then apply a small piece of adhesivetape over the area7. When you pull up the tape，you'll see that it pulls up a thin layer of some ofthe shading from your pencil. That layer is called graphite，one of the softest minerals in the world.Now stick the same piece of tape on another sheet of paper and pull the tape up —there should be an even thinner layer，this time left on the paper. Now imagine that you do this over and over，until you get the thinnest possible layer of material on the paper. This layer would be only one atom thick，and you wouldn't be able to see it. Graphite is made of layers of graphene，so when you get to the thinnest possible layer，you've found graphene.词汇：graphene/ 'græfi:n/ n．石墨烯abundant/ə’bʌndənt / adj．丰富的，充裕的atom/ 'ætəm/n．原子adhesive/ əd'hi:siv/ n．胶粘剂；adj. 黏着的stack/stæk/ v．使成堆，堆放graphite / 'græfait / n．石墨注释：1. superstrength：超强的力量。

2012职称英语理工参考译文第二部分阅读判断第一篇LED的发明者当Nick Holonyak着手用半导体含金创造一种新的可视照明设备的时候，同事们都认为他不现实。

今天，他发现的发光二极管，或叫LED，使用范围覆盖从DVD到机场警钟的一切东西。

他的许多学生继续着他的工作，发明了交通灯中使用的照明设备和其他的日用技术。

2004年4月23号，Holoyak在华盛顿的一次典礼上被授予Lemelson-MIT项目的50万美元的奖金。

这是麻省理工的Lemelson-MIT项目第十年颁奖给杰出的发明人。

“任何时候你得了奖，不论是大是小，总是一分惊喜。

”Holonyad说。

Holonyak，75岁，是20世纪50年代初期晶体管的发明者John Bardeen的学生。

从研究生院毕业之后，Holonyak 在Bell实验室工作。

之后去了通用电器公司，在那里他发明了一种开关，现在家用减光开关中普遍使用。

后来，Holonyak开始研究如何应用半导体发电。

当他的同事们正在研究如何发出看不见的光时，他却想要看得见的光。

1962年他发明的LED，现在的使用寿命可以比白炽灯泡长十倍，而且更环保、更经济。

Holonyak现在是伊利诺斯大学电子、计算机工程和物理专业的教授，他说他预料到LED的使用有可能像今天这样普遍，但没有意识到它会有多少用途。

“开始的时候你并不知道，你认为你在做一件很重要的事情，你认为它值得做，但是你不能说出要付出多大的代价，什么时候付出，怎样付出。

你并不知道。

”他说。

Lemelson-MIT项目同样授予75岁的Edith Flanigen 10万美元的终身成就奖，她的成就是创造新一代的“分子筛”，也就是可以通过大小来分离分子。

第二篇厄尔尼诺当某些预报方法不能提前几个月成功预测1997年厄尔尼诺现象的时候，哥伦比亚大学的研究人员说他们的方法可以提前两年预测厄尔尼诺现象。

这对全世界各地的政府、农民和其他寻求为厄尔尼诺带来的干旱和大雨做准备的人来说是一条好消息。

*第三＋八篇"Life Form Found" on Saturn's Titan Scientists say they have discovered hints of alien life1 on the Saturn's moon2. The discovery of a sort of life was announced after researchers at the US space agency,NASA3,analyzed data from spacecraft Cassini4,which pointed to,the existence of methane-based form of life on Saturn's biggest moon.Scientists have reportedly discovered clues showing primitive alien beings are"breathing" inTitan's dense atmosphere filled with hydrogen.They argue that hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane lakes and rivers. This,they say,points to the existence of some"bugs"5 consuming the hydrogen at the surface of the moon less than half the size of the Earth."We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan,similar to the way we consume oxygen on Earth,"says NASA scientist Chris McKay."If these signs do turn out to be a sign of life,it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth."To date,scientists have not yet detected this form of life anywhere,though there are liquid-water-based microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan, where temperatures are around 90 Kelvin6(minus 290 degrees Farenheit),a methanebased organism would have to use a substance that is liquid as its medium for living processes, but not water itself. Water is frozen solid on Titan's surface and much too cold to support life as we know it.Scientists had expected the Sun's interactions with chemicals in the atmosphere to produce a coating of acetylene on Titan's surface. But Cassini detected no acetylene on the surface.The absence of detectable acetylene on the Titan's surface can very well have a non-biological explanation,said Mark Allen,a principal investigator7of the NASA Titan team."Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed,"Allen said. "We have a lot of work to do to rule out8possible non-biological explanations. It is more likely that a chemical process,without biology,can explain these results."词汇：Saturn /'sætən/ n．土星methane/'mi:θein/ n．甲烷，沼气Titan/'taitən/ n．土卫六acetylene/ə'setili:n/ n．乙炔alien/'eiljən/ n．外星人；adj．外星球的；相异的conservatism/kən'sʒ:vətizəm/ n．保守主义,守旧注释：1.hints of alien life：外星生命迹象。

阅读理解+第四＋五篇 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 objects2in 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 seeing 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 pictures 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 takespictures of features that give off infrared radiation6.Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of light7that 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 waves of 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.小而聪明12月14日，美国国家航空航天局发射了一个体积小而威力大的望远镜，它的名字叫“WISE”（聪明），大约只有一个垃圾盒子那么宽。

Telling Tales about PeopleOne of the most common types of nonfiction, and one that many people enjoy reading, is stories about people's lives. These stories fall into three general categories: autobiography, memoir, and biography.An autobiography is the story of a person's life written by himself or herself. Often it begins with the person's earliest recollections and ends in the present. Autobiography writers may not be entirely objective in the way they present themselves. However, they offer the reader a good look at the way they are and what makes them that way. People as diverse as Benjarmin Franklin and Helen Keller have written autobiographies. 1Other writers, such as James Joyce，have written thinly fictionalized accounts of their lives. These are not autobiographies，but they are very close to it.Memoirs, strictly speaking, are autobiographical accounts that focus as much on the events of the times as on the life of the author. 2Memoir writers typically use these events as backdrops for their lives. They describe them in detail and discuss their importance. Recently，though，the term memoir seems to be becoming interchangeab1e with autobiography. A memoir nowadays may or may not deal with the outside world.Biographies are factual accounts of someone else's life. In many senses，these may be the hardest of the three types to write. Autobiography writers know the events they write about because they lived them. But biography writers have to gather information from as many different sources as possible. Then they have to decide which facts to include. Their goal is to present a balanced picture of a person，not one that is overly positive or too critical. A fair well-presented biography may take years to research and write.词汇：backdrop n. 背景interchangeable adj. 可转换的注释：1. People as diverse as Benjamin Franklin and Helen Keller have written autobiographies. 就像本杰明?富兰克林和海伦?凯勒一样，各种各样的人们已经写了自传。

They may use 2、different currencies, but these countries, and probably all countries, still have one thing in common1: Germs on the banknotes.Scientists have been studying the germs on money for well over2 100 years. At the turn of the 20th 3、century , some researchers began to suspect that germs living on money could spread disease.Most studies of germy money have looked at the germs on the currency 4、within one country. In a new study, Frank Vriesekoop3 and other researchers compared the germ populations found on bills of different 5、countries .Vriesekoop3 is a microbiologist at the University of Ballarat in Australia4. He led the study, which compared the germ populations found on money 6、gathered from 10 nations. The scientists studied 1,280 banknotes in total; all came from places where people buy food, like supermarkets street vendors and cafes, 7、because those businesses often rely on cash.Overall, the Australian dollars hosted the fewest live bacteria ---- no more than 10 per square centimeter. Chinese yuan had the most ---- about 100 per square centimeter. Most of the germs on money probably would not cause harm.What we call “paper” money usually isn't made from paper. The U. S. dollar, for example, is printed on fabric that is mostly 8、cotton .Different countries may use different 9、materials to print their money. Some of the currencies studied by Vriesekoop and his 10、team such as the American dollar were made from cotton. Others were made from polymers.The three 11、currencies with the lowest numbers of bacteria were all printed on polymers. They included the Australian dollar, the New Zealand dollar and some Mexican pesos.The other currencies were printed on fabric made 12、mostly of cotton. Fewer germs lived on the polymer notes. This connection suggests that 13、germs have a harder time staying alive on polymer surfaces. Scientists need to do more studies to understand how germs live on money-----and whether or not we need to be concerned. Vnesekoop is now starting a study that will 14、compare the amounts of time bacteria can stay alive on different types of bills.Whatever Vriesekoop finds, the fact remains: Paper money harbors germs We should wash our 15、hands after touching it; after all5, you never know where your money 's been. Or what's living on it注释：第十篇 Chicken Soup for the Soul：Comfort Food Fights Loneliness Mashed potatoes, macaroni and cheese, may be bad for your arteries．1、 but according to a study in Psychological Science, they’re good for your heart and2、emotions The study focuses on “comfort food” and how it makes people feel．"For me 3、personally ,food has always played a big role in my family,” says Jordan Troisi, a graduate student at the University of Buffalo, and lead author on the study．The study came out of the research program of his co—author Shira Gabriel．It has 4、looked at non-human things that may affect human emotions．Some people reduce loneliness by bonding with their 5、 favorite TV show, building virtual relationships with a pop song singer or looking at pictures of loved ones．Troisi and Gabriel wondered if comfort food could have the same effect 6、by making peoplethink of their nearest and dearest. In one experiment, in order to make 7、participants feel lonely, the researchers had them write for six minutes about a fight with someone close to them．Others were given an emotionally neutral writing assignment. Then, some people in each 8、 group wrote about the experience of eating a comfort food and others wrote about eating a new food．9、Finally ,the researchers had participants 10、 complete questions about their levels of loneliness．Writing about a fight with a close person made people feel lonely．But people who were generally 11、secure in their relationships would feel less lonely by writing about a comfort food．"We have found that comfort foods are consistently associated with those close to us．"says Troisi．"Thinking about or consuming these foods later then serves as a reminder of those close others．"In 12、their essays on comfort food, many people wrote about the 13、experience of eating food with family and friends. In another experiment, 14、 eating chicken soup in the lab made people think more about relationships, but only if they considered chicken soup to be a comfort food．This was a question they had been asked long before the experiment, along with many other questions, so they wouldn’t remember it. Throughout everyone’s daily lives they experience stress, often associated with our 15、connections with others," Troisi says．"Comfort food Can be an easy remedy for loneliness．*第十一篇 Climate Change Poses Major Risks for Unprepared Cities （B级完型）A new examination of urban policies has been 1、carriedout recently by Patricia Romero Lankao．She is a sociologist specializing in climate change and 2 、urban development．She warns that many of the world’s fast-growing urban areas，especially in developing countries．will likely suffer from the impacts of changing climate．Her work also concludes that most cities are failing to 3、reduce emissions of carbon dioxide and other greenhouse 4、gases．These gases are known to affect the atmosphere．”Climate change is a deeply local issue and poses profound threats to the growing cities of the world,” says Romer o Lankao. ”But too few cities are developing effective strategies to 5、protect their residents."Cities are 6、major sources of greenhouse gases．And urban populations are likely to be among those most severely affected by future climate ch ange. Lankao’s findings highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term 7 、benefits．The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential 8、threats associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat 9、heavily paved cities more than surrounding areas．The impacts of such natural events can be more serious in an urban environment．For example，a prolonged heat wave can increaseexisting levels of air pollution，causing widespread health problems．Poorer neighborhoods that may 10、lack basic facilities such as drinking water or a dependable network of roads，are especially vulnerable to natural disasters．Many residents in poorer countries live in substandardhousing 11、without access to reliable drinking water，roads and basic services.Local governments, 12、therefore ,should take measures toprotect their residents.”Unfortunately，they tend to move towards rhetoric 13、rather than meaningful responses, Romero Lankao writes, ” They don’t impose const ruction standards that could reduce heating and air conditioning needs. They don't emphasize mass transit and reduce 14 、 automobile use. In fact, many local governments are taking a hands—off approach.” Thus, she urges themto change their 15 、idle policies and to take strong steps to prevent the harmful effects of climate change on cities.*第十二篇 Free Statins With Fast Food Could Neutralize Heart Risk（B 级完型）Fast food outlets could provide statin drugs free of 1、charge so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London 2、suggest in a newstudy．Statins reduce the 3 、 amount of unhealthy ”LDL” cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person’s heart attack 4 、risk .In a paper published in the American Journal of Cardiology，Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is 5、enough to offset the increase in heart attack risk from 6、eating a cheeseburger and drinking a milkshake．Dr Francis，from the National Heart and Lung Institute at Imperial College London，who is the senior author of the study, said:”Statins don’t cut out a11 of the 7、unhealthy effects of cheeseburgers and French fries．It’s better to avoid fatty food altogether．But we’ve worked out that in terms of your 8、possibility of having a heart attack. Taking a statin can reduce your risk to more or less the same 9、degree as a fast food meal increases it.”“It’s ironic that people are free to take as many unhealthv condiments in fast food outlets as they 10、like , but statins, which are beneficial to heart health, have to be prescribed. It makes sense to make risk-reducing statins available just as easily as the unhealthy condiments that are 11、provided free of charge．It would cost less than 5 pence per 1 2、 customer 一not much different to a sachet of sugar.” Dr Francis s aid．When people engage in risky behaviours like driving or smoking, they’re encouraged to take 13、measures that lower their risk, 1ike 14 wearing a seatbelt or choosing cigarettes with filters.

Until now, scientists thought the2、effects of the magnetic field were so weak that they could be ignored. What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than 3、previously expected. 4、Under these circumstances, the magnetic effects develop strength equivalent to a strong electric effect."This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation," Rand said. "In solar cells, the 5、light goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load2. Instead of the light being absorbed, energy is stored in the magnetic moment3. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power6、source."What makes this possible is a previously undetected brand of "optical rectification4," says William Fisher, a doctoral student5 in applied physics. In traditional optical rectification, light's electric field causes a charge separation, or a pulling7、apart of the positive and negative charges6 in a material. This sets up a voltage, similar to 8、that in a battery.Rand and Fisher found that under the right circumstances and in right types of materials, the light's magnetic field can also create optical rectification. The light must be shone through7 a 9、material that does not 10、conduct electricity, such as glass. And it must be focused to an intensity of 10 million watts per square centimeter8. Sunlight isn't this intense on its own, but new materials are being sought that would work at lower intensities, Fisher said."In our most recent paper, we show that incoherent light9 like sunlight is theoretically almost as. 11、effective in producing charge separation as laser light is," Fisher said.This new 12、technique could make solar power cheaper, the researchers say. They predict that with improved materials they could achieve 10 percent efficiency in 13、converting solar power to useable energy. That's equivalent to today's commercial-grade solar cells."To manufacture 14 、modern solar cells, you have to do extensive semiconductor processing," Fisher said. "All we would need are lenses to focus the light and a fiber to guide it. Glass works for 15、both . It's already made in bulk10, and it doesn't require as much processing. Transparent ceramics might be even better."+第十五篇“Liquefaction” Key to Much of Japanese Earthquake Damage（A级完型）The massive subduction zone1earthquake in Japan caused a significant level of soil"liquefaction"2 that has surprised researchers with its 1、widespread severity, a new analysis shows."We've seen localized3 examples of soil liquefaction as extreme as this before, but the distance and 2、extent of damage in Japan were unusually severe," said Scott Ashford, a professor of geotechnical engineering4 at Oregon State University5. "Entire structures were tilted andsinking into the sediments," Ashford said. "The shifts in soil destroyed water, drain and gas pipelines6, crippling the utilities and infrastructure these communities need to 3、function . We saw some places that sank as much as four feet."Some degree of soil liquefaction7is common in almost any major earthquake. It's a phenomenon in which soils soaked with water, particularly recent sediments or sand, can lose much of their 4 、strength and flow during an earthquake. This can allow structures to shift or sink or 5、collapse .But most earthquakes are much 6、shorter than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this8."With such a long-lasting earthquake, we saw 7、how structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes," he said. "And it was clear that younger sediments, and especially areas built on 8、recently f illed ground, are much more vulnerable."The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil 9、phenomenon and better prepare for it in the future. Ashford said it was critical for the team to collect the information quickly, 10、before damage was removed in the recovery efforts9."There's no doubt that we'll learn things from what happened in Japan10 that11will help us to reduce risks in other similar 11、events ," Ashford said. "Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns."Ashford pointed out that northern California have younger soils vulnerable to liquefaction ---on the coast, near river deposits or in areas with filled ground. The "young" sediments, in geologic terms, may be those 12、deposited within the past 10,000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.Anything 13、near a river and old flood plains is a suspect12, and the Oregon Department of Transportation has already concluded that 1,100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have been reinforced to 14、prevent collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction 15、standards helped prevent many buildings from collapse ---even as they tilted and sank into the ground.轻松词汇通轻轻松松词汇通，稳拿满分在其中一、解释版：（一）必记：10大词汇选项要求掌握的单词：（03年8对8分，04年8对8分，05年8对两半10分）（斜体部分为近两年已考）1\account for=explain 理解minute=slight 细小disorder=confusion混乱Accused of=charged with 指控investigate=look into 调查numerous=many 许多obvious=clear 显而易见Odd=strange 奇怪participate in=take part in 参加preserve=keep 保存previously=before以前pull up=stop 停止perceive=notice 注意到possess=own占有substantial=significant 实质的2\spur=encourage 激励coverage=reportage报道dimly=faintly 昏暗(048)，模糊mildly=gently 温和地inevitable=certain 不可避免isolate=solitary 孤立的call of=cancel取消make up one’s mind=decide决定Now and then=occasionally=sometimes 有时find fault with=criticize 批评grasp=take hold of抓住Consideration=account 考虑tolerate=put up with 忍受abandon=give up 放弃lately=recently最近3\Manual=physical 人工harness=utilise(utilize) 利用resident=occupant 居民steadily=continuously不断地Remedy=cure治疗(055)draft==formulate起草practically=almost 几乎endeavor=try=test尝试seldom=rarely 很少而精Readily=willingly 乐意shine=polish 擦亮Extract=take out 取出(045)decent=honest正派Lethal=Deadly=fatal 致命的4\insist on=demand 坚持speed=velocity快过Physician=doctor 医生particularly=especially特别safe=secure安全的branch=division分支机构Abnormal=unusual 不正常的accelerate=step up 加快abundant=plentiful 丰富的accumulate=collect积累Allocate=distribute=assign 分配childish=immature 幼稚barren=bare贫瘠5\appalling=dreadful讨厌的Anyhow=anyway 不管achieve=attain 通过努力达到capability=ability 能力in conjunction=together共同Credible=convincing 可信的diligent=hardworking 勤奋diverse=varied多种多样faulty=wrong有错的Gorgeous=lovely 极美的persist=continue 持续regulate=control 控制scatter=separate分开Stand point=point of view 观点touching=moving 感人的6\vanish=disappear消失phase=stage阶段Deter=inhibit=prevent 阻止porcelain=china 陶瓷prior to=before在。

They may use 2 currencies, but these countries, and probably all countries, still have one thing in common1: Germs on the banknotes.Scientists have been studying the germs on money for well over2 100 years. At the turn of the 20th 3 , some researchers began to suspect that germs living on money could spread disease.Most studies of germy money have looked at the germs on the currency 4 one country. In a new study, Frank Vriesekoop3 and other researchers compared the germ populations found on bills of different 5 .Vriesekoop3 is a microbiologist at the University of Ballarat in Australia4. He led the study, which compared the germ populations found on money 6 from 10 nations. The scientists studied 1,280 banknotes in total; all came from places where people buy food, like supermarkets street vendors and cafes, 7 those businesses often rely on cash.Overall, the Australian dollars hosted the fewest live bacteria ---- no more than 10 per square centimeter. Chinese yuan had the most ---- about 100 per square centimeter. Most of the germs on money probably would not cause harm.What we call “paper” money usually isn't made from paper. The U. S. dollar, for example, is printed on fabric that is mostly 8 .Different countries may use different 9 to print their money. Some of the currencies studied by Vriesekoop and his 10 such as the American dollar were made from cotton. Others were made from polymers.The three 11 with the lowest numbers of bacteria were all printed on polymers. They included the Australian dollar, the New Zealand dollar and someMexican pesos.The other currencies were printed on fabric made 12 of cotton. Fewer germs lived on the polymer notes. This connection suggests that 13 have a harder time staying alive on polymer surfaces. Scientists need to do more studies to understand how germs live on money-----and whether or not we need to be concerned. Vnesekoop is now starting a study that will 14 the amounts of time bacteria can stay alive on different types of bills.Whatever Vriesekoop finds, the fact remains: Paper money harbors germs We should wash our 15 after touching it; after all5, you never know where your money 's been.

2012年职称英语理工类新增文章+第四＋五篇 Teaching Math, Teaching Anxiety+第四十六篇Ants Have Big Impact on Environment as "Ecosystem+第四十六篇Ants Have Big Impact on Environment as "Ecosystem Engineers"Research by the University of Exeter1 has revealed that ants have a big impact on their local environment as a result of their activity as "ecosystem engineers" and predators. The study, published in the Journal of Animal Ecology, found that ants have two distinct effects on their local environment.Firstly, through moving of soil by nest building2 activity and by collecting food they affect the level of nutrients in the soil. This can indirectly impact the local populations of many animal groups, from decomposers to species much higher up the food chain.Secondly, they prey on a wide range of other animals, including larger prey which can be attacked by vast numbers of ant workers.Dirk Sanders, an author of the study from the university's Centre for Ecology and Conservation, said:"Ants are very effective predators which thrive in huge numbers. They're also very territorial3 and very aggressive, defending their resources and territory against other predators. All of this means they have a strong influence on their surrounding area.""In this research, we studied for the first time how big this impact is and the subtleties of it. What we found is that despite being predators, their presence can also lead to an increase in density and diversity of other animal groups4. They genuinely play a key role in the local environment, having a big influence on the grassland food web," Sanders said.The study, carried out in Germany, studied the impact of the presence of different combinations and densities of black garden ants and common red ants, both species which can be found across Europe, including in the UK. It found that a low density of ants in an area increased the diversity and density of other animals in the local area,particularly the density of herbivores and decomposers. At higher densities ants had no or the opposite effect, showing that predation is counteracting the positive influence.Dr Frank van Veen, another author on the study, said:"What we find is that the impact of ants on soil nutrient levels has a positive effect on animal groups at low levels, but as the number of ants increases, their predatory impacts have the bigger effect — thereby counteracting the positive influence via ecosystem engineering."Ants are important components of ecosystems not only because they constitute a great part of the animal biomass5 but also because they act as ecosystem engineers. Ant biodiversity6is incredibly high and these organisms are highly responsive to human impact, which obviously reduces its richness. However, it is not clear how such disturbance damages the maintenance of ant services to the ecosystem．Ants are important in below ground processes8 through the alteration of the physical and chemical environment and through their effects on plants, microorganisms, and other soil organisms.词汇：predator /' predətə/ n．食肉动物nutrient/' nju:triənt/ n ．营养物；adj．营养的decomposer/,di:kəm'pəuzə/ n．腐生物；分解体prey/prei/ v．捕食；n．被捕食的动物subtlety/ 'sʌtlti/ n ，微妙，精妙herbivore/ 'hʒ:bivɔ: / n ．食草动物注释：1.the University of Exeter ：埃克斯特大学。

Similar to your bedside alarm clock，your internal clock2 runs on a 24-hour cycle. This cycle，called a circadian rhythm，helps control when you wake，when you eat and when you sleep.Somewhere around puberty，something happens in the timing of the biological clock. Theclock pushes forward，so adolescents and teenagers are unable to fall asleep as early as they used to. When your mother tells you it's time for bed，your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later.This shift4 is natural for teenagers. But staying up very late and sleeping late can get your body's clock out of sync with the cycle of light and dark5. It can also make it hard to get out of bed in the morning and may bring other problems，too. Teenagers are put in a kind of a gray cloud6when they don't get enough sleep，says Mary Carskadon，a sleep researcher at Brown University in Providence，RI7 .It affects their mood and their ability to think and learn.But just like your alarm clock，your internal clock can be reset. In fact，it automatically resets itself every day. How? By using the light it gets through your eyes.Scientists have known for a long time that the light of day and the dark of night play important roles in setting our internal clocks. For years，researchers thought that the signals that synchronize the body's clock8were handled through the same pathways that we use to see.But recent discoveries show that the human eye has two separate light-sensing systems. One system allows us to see. The second system tells our body whether it's day or night.词汇：circadian/s3:'keidiən/ adj. 昼夜节奏的，生理节奏的adolescent/ædəu'lesənt/ n．青少年；adj．青少年的puberty/ 'pju:bəti/ n．发育；青春期sync/siŋk/ n. （口语）同步；和谐，协调synchronize/'siŋkrənaiz / V.（使）同时发生；（使）同步注释：1.make light of ：轻视，不在乎。

这些国家的纸币形状也可能不一致，但所有国家的纸币都具有一个共同点：纸币上有病菌。

一百多年以来，科学家们对纸币上病菌的研究从未停止过。

在二十世纪初期，一些研究人员开始怀疑寄附于纸币上的病菌极有可能传播疾病。

对纸币上病菌的研究大多着眼于某一国家的纸币。

Frank Vriesekoop博士和其他研究人员进行了一项新的研究，即比较不同国家纸币上的病菌总数。

Frank Vriesekoop博士是巴拉瑞特大学的食品微生物学家，他率领一个全球研究小组对至少10个国家的纸币上的病菌展开了分析。

科学家们总共分析了1，280张纸币：所有纸币来自于人们购买食物的地方，如超市、街头小贩和咖啡厅，因为人们在那些地方往往会使用纸币。

总体来说，澳元中的活病菌最少，每平方厘米只有10个；中国人民币的病菌最多，大约每平方厘米100个。

第六篇不要太在意睡眠我们每个人的大脑里都有一个像我们床边的闹钟一样的生物钟。

人脑里的生物钟24小时走一圈，这一圈也就是一次完整的昼夜节律，正是这个节律决定了我们吃饭、睡觉和起床的时间。

青春期时，人的生物钟在定时方面会发生变化，生物钟会提前。

这时，青少年会比以前睡得晚，所以当你妈妈告诉你该睡觉时，你的生物钟可能会让你多推迟几小时，并且电脑或电视光线可能会导致你熬夜到更晚。

生物钟的这种变化对青少年说是正常的，但熬夜到太晚会打乱你生物钟与昼夜时间循环之间的平衡，这样就会带来一些问题，例如：早晨很难按时起床。

位于美国罗得州布郎大学睡眠方面的研究员Mary Carskadon说：“当青少年睡眠不足时会打不起精神，这将影响到他们心情、学习和思考问题的状态。

”其实生物钟与闹钟一样，也是可调的，事实上，生物钟每天都在进行着自我调节，其方式就是通过你眼睛接收到光线的变化。

很早之前，科学家就知道了昼夜光线强弱的变化对生物钟调节起到了重要的作用，长久以来，研究者们认为眼睛所接受到的平衡生物钟的光信号同样作用于人类的视觉系统。

但最近几年的研究发现，人类眼睛有两个感光系统，一个是视觉系统，而另一个是感知昼夜的系统。

第十九篇石墨烯的超强力量当今重大科学技术均以“微型”来呈现，新手机和个人电脑每年都在变得更小，这就意味着电子设备要求内部零件更小，工程师们正在寻求制造这些零件的方法，他们逐渐把目光投向了石墨烯——一种由碳元素构成的超薄材料。

这种材料将改变电子设备的未来。

今年的诺贝尔物理学奖颁发给了来自英国曼切斯特大学的Andre Geim和Kostya Novoselov，以表彰他们对石墨烯的发现。

Novoselov说：“石墨烯不仅小，而且它是世界上所能找到的最薄材料。

”他把它称作“神奇材料”。

石墨烯极薄，25 000片石墨烯叠放在一起才与一张普通白纸一样厚。

如果把一片石墨烯放在手指上，你根本就不会发现，因为你没办法看到它。

碳是宇宙中最多的一种元素，已知的生命体中都含有碳。

理工类C级第三篇纸币上的病菌不同国家的人们使用不同种类的纸币：中国用元，墨西哥用比索，英国用英镑，美国用美元、澳大利亚用澳元、新西兰用新西兰元。

这些国家的纸币形状也可能不一致，但所有国家的纸币都具有一个共同点：纸币上有病菌。

一百多年以来，科学家们对纸币上病菌的研究从未停止过。

在二十世纪初期，一些研究人员开始怀疑寄附于纸币上的病菌极有可能传播疾病。

对纸币上病菌的研究大多着眼于某一国家的纸币。

Frank Vriesekoop博士和其他研究人员进行了一项新的研究，即比较不同国家纸币上的病菌总数。

Frank Vriesekoop博士是巴拉瑞特大学的食品微生物学家，他率领一个全球研究小组对至少10个国家的纸币上的病菌展开了分析。

科学家们总共分析了1，280张纸币：所有纸币来自于人们购买食物的地方，如超市、街头小贩和咖啡厅，因为人们在那些地方往往会使用纸币。

总体来说，澳元中的活病菌最少，每平方厘米只有10个；中国人民币的病菌最多，大约每平方厘米100个。

纸币上的病菌大多不会有危害。

我们所说的“纸币”通常不是纸做的。

例如，美元是印在一种棉织物上。

不同的国家可能会用不同的材料印制货币。

Vriesekoop和他的研究团队所分析的货币中有的是棉制品，比如美元。

其他的是由聚合物所制成的。

有三种纸币上的病菌的数量最少，它们是澳元、新西兰元和墨西哥比索，而且它们都是印在聚合物上。

其他的纸币都是印在高棉制品上。

而用聚合物印制的纸币上的病菌较少。

这种关系表明，病菌在聚合物的表面上更难以存活。

科学家们若想搞清楚病菌是怎样在纸币上生存的以及我们是否需要重视这些病菌，需要做更多的研究。

Vriesekoop目前所做的研究就是比较在不同类型的纸币上病菌存活的时间。

无论Vriesekoop的研究有何发现，毋庸置疑的是：纸币含有病菌。

我们接触纸币后应立即洗手。

毕竟，你永远不会知道你的纸币的来源，或者上面有什么东西。

第四部分阅读理解第一篇福特放弃电动汽车分析人士评论，福特汽车公司放弃电动汽年的举动有力地证明了这种技术是行不通的。

通用汽车公司和日本本田汽车公司早于1999年就停止了电池动力汽车的生产，转而开发燃料电池和电池内燃混合机，这对消费者更有吸引力。

福特宣布它现在也要做同样的尝试。

3年前，福特推出名为Think City的双排座汽车和Think或Think Neighbor系列高尔夫车，希望能销售5000辆汽车、10000高尔夫车。

但由于需求不足，截至2002年仅生产了大约1000辆汽车，售出的高尔夫车还不足1700辆。

“关键是我们认为电动车不能代表大众市场环保交通的未来”，福特欧洲区的Tim Holmes于周五说，“我们感觉自己对电力车已做了昀好的尝试。

”Think City系列的运行里程仅53英里，电池充电需6小时。

通用公司的EVI电力车也仅能运行100英里。

昂贵的电池也意味着电动汽车的造价比汽油动力车高出许多。

日本丰田产的RAV4EV系列电动车在美国的售价达42000美元，而同系列的汽油动力车仅售17000美元。

丰田和日产汽车公司是现在仅存的两大电动车制造商。

“应该说电池动力车已经获得了充分的机会。

福特现已转向电池内燃混合机开发项目，我们应据此评价他们的发展。

”Roger Higman，英国Friends of the Earth组织的一位高级交通运动代表这样对《环保新闻》评论说。

日本本田和丰田公司推出的混合机汽车在过去几年取得了良好的销售业绩。

混合动力车比汽油机车运行里程更长，电池又可自行充电。

福特表示，他们认为这样的机车有助于达到美国新制订的车辆排放规定。

不过，这些规定究竟允许怎样的排放物现在还不十分清楚。

六月份通用和戴姆勒克莱斯勒公司赢得一项法庭裁决，可推迟两年执行一项加州法令，该法令要求汽车生产商在2003年前向该州提供10万辆零排放和其他低排放汽车。

制造商希望修改此法令，允许他们生产更多低排放而不是零排放的汽车。
