Their study is in ACS’Energy&Fuels1.Ibrahim Nashawi and colleagues point out that rapid growth in global oil consumption has sparked a growing interest in predicting "peak oil". "Peak oil" is the point where oil production reaches a maximum and then declines. Scientists have developed several models to forecast this point，and some put the date at 2020 or later. One of the most famous forecast models is called the Hubbert model2.It assumes that global oil production will follow a bell shaped curve3.A related concept is that4 of "Peak Oil." The term "Peak Oil" indicates the moment in which world wide production will peak，afterwards to start on irreversible decline.The Hubbert model accurately predicted that oil production would peak in the United States in 1970.The model has since gained in popularity and has been used to forecast oil production worldwide.However，recent studies show that the model is insufficient to account for5 more complex oil production cycles of some countries. Those cycles can be heavily influenced by technology changes，politics，and other factors，the scientists say.The new study describes development of a new version of the Hubbert model that provides a more realistic and accurate oil production forecast. Using the new model，the scientists evaluated the oil production trends of 47 major oil-producing countries，which supply most of the world’s conventional crude oil6.They estimated that worldwide conventional crude oil production will peak in 2014，years earlier than anticipated. The scientists also showed that the world’s oil reserves7are being reduced at a rate of 2.1 percent a year. The new model could help inform energy-related decisions and public policy debate，they suggest.词汇：conserve v.保护，保存 irreversible adj.不可逆的，不可改变的crude oil原油spark v.闪耀;激发;鼓舞 insufficient 不充分的，不足的curve n.曲线注释：1.ACS’Energy&Fuels：ACS是American Chemical Society(美国化学学会)的缩写。
2011年职称英语理工A、B级新增文章含个人翻译46奇妙的超级材料
Marvelous metamaterialsInvisibility cloaks would have remained impossible, forever locked in science fiction, had it not been for the development of metamaterials. In Greek, “meta” means beyond, and metamaterials can do things beyond what we see in the natural world — like shuffle light waves around an object, and then bring them back together. If scientists ever manage to build a full-fledged invisibility cloak, it will probably be made of metamaterials.“We are creating materials that don’t exist in nature, and that have a physical phenomenon that doesn’t exist in nature,” says engineer Dentcho Genov. “That is the most exciting thing.”Genov designs and builds metamaterials — such as those used in cloaking — at Louisiana Tech University in Ruston, Louisiana.An invisibility cloak will probably not be the first major accomplishment to come from the field of metamaterials. Other applications are just as exciting. In many labs, for example, scientists are working on building a hyperlens.A lens is a device — usually made of glass — that can change the direction of light waves. Lenses are used in microscopes and cameras to focus light, thus allowing a researcher to see small things or a photographer to capture image of things that are far away.A hyperlens, however, would be made of metamaterials. And since metamaterials can do things with light that ordinary materials can’t, the hyperlens would be a powerful tool. A hyperlens would allow researchers to see things at the smallest scale imaginable — assmall as the wavelength of visible light.Genov points out that the science of metamaterials is driven by the imagination: If someonecan think of an idea for a new behavior for light, then the engineers can find a way to design adevice using metamaterials. “We need people who can imagine,” he says.奇妙的超级材料Invisibility cloaks would have remained impossible, forever locked in science fiction, had it not been for the development of metamaterials.如果不是被超材料的发展，隐形斗篷将仍然是不可能的，永远只会存在科幻小说里，。

2011年职称英语理工类考试教材新增文章汇总A级完型填空新增文章教材第十五篇文章Young Adults Who Exercise Get Higher IQ ScoresYoung adults who are fit have a higher IQ and are more likely to go on to university，reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital．The results were recently published in the Proceedings of the National Academy of Sciences (PNAS)．The study involved l.2 million Swedish men doing military service who were born between l950 and l976．The research group analysed the results of both physical and IQ tests the youngsters took fight after they started serving the army．The study shows a clear link between good physical fitness and better results for the IQ test．The strongest links are for logical thinking and verbal comprehension．But it is only fitness that plays a role in the results for the IQ test，and not strength．“Being fitmeans that you also have good heart and lung capacity and that your brain gets plenty of oxygen，”says Michael Nilsson，professor at the S ahlgrenska Academy and chief physician at the Sahlgrenska University Hospital．“This may be one of the reasons why we can see a clear link with fitness，but not with muscular strength．We are also seeing that there are growth factors that are important．”By analysing data for twins，the researchers have been able to determine that it is primarily environmental factors and not genes that explain the link between fitness and a higher IQ．“We have also shown that those youngsters who improve their physical fitness between ages of l5 and l8 increase their cognitive performance," says Mafia Aberg，researcher at the Sahlgrenska Academy and physician at Aby health centre．“This being the case6，physical during is a subject that has anresearcher Michael Chaiton，a research associate at the Ontario Tobacco Research Unit of the University of Toronto．“Although cigarettes may appear to have self-medicating effects or to improve mood，in the long term we found that teens who started to smoke reported higher depressive symptoms.”As part of the study，some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to affect mood．Secondary schools were selected to provide a mix of French and English participants，urban and rural schools，and schools located in high, moderate and low socioeconomic neighbourhoods．Participants were divided into three groups: never smokers；smokers who did not use cigarettes to self-medicate，improve mood or physical state；smokers who used cigarettes to self-medicate．Depressivesymptoms were measured using a scale that asked how felt too fired to do things：had trouble going to sleep or staying asleep；felt unhappy，sad，or depressed；felt hopeless about the future；felt vexed，antsy or tense；and worried too much about things．"Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer 0’Loughlin，a professor at the University of Montreal Department of Social and Preventive Medicine．"0ur study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."The association between depression and smoking exists principally among teens that usecigarettes to feel better．"It’s important to emphasize that depressive symptom scores were higher among teenagerswho reported emotional benefits from smoking after they began to smoke," says Dr．Chaiton．C级完型填空新增文章教材第三篇文章What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃which occurred in Antarctica in 1983．We encounter an interesting situation when we discuss temperatures in space. Temperatures in Earth orbit actually range from about +120℃ to -120℃．The temperature depends upon whether you are in direct sunlight or shade．Obviously, -l20℃is colder than our body can safely endure．Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes．The space temperatures just discussed affect only Our area of the solar system．Obviously，it is hotter closer to theSun and colder as we travel away from the Sun．Astronomers estimate temperatures at Pluto are about -210℃．How cold is the lowest estimated temperature in the entire universe? Again，it depends upon your location．We are taught it is supposedly impossible to have a temperature below absolute zero，which is-273℃，at which atoms do not move．Two scientists，whose names are Cornell and Wieman，have successfully cooled down a gas temperature barely above absolute zero．They won a Nobel Prize in Physics in 2001 for their work—not a discovery，in this case．Why is the two scientists' work so important to science?In the l920s，Satyendra Nath Bose was studying an interesting theory about particles we now call photons．Bose had trouble convincing other scientists to believe so he contacted Albert Einstein．Einstein's calculations helped him theorize would behave as Bose thought——but only at very cold temperatures．Scientists have also discovered that ultra-cold atoms can help them make the world's atomic clocks even more accurate．These clocks are so accurate today they would only lose 0ne second every six million years! Such accuracy will help us travel in space because distance is velocity times time (d=v×t)．With the long distances involved in space travel to know time as accurately as possible to get accurate distance．A级阅读理解新增文章教材第四十六篇文章Marvelous MetamaterialsInvisibility cloaks would have remained impossible，forever locked in science fiction．had it not been for the development of metamaterials. In Greek, "meta" means beyond, and metamaterials car do things beyond what we see in the natural world—like shuffle light waves around an object，and then bring them back together．Ifscientists ever manage to build a full—fledged invisibility cloak，it will probably be made of metamaterials．"We are creating materials that don't exist in nature, and that have a physical phenomenon that doesn't exist in nature," says engineer Dentcho Genov. "That is the most exciting thing." Genov designs and builds metamaterials--such as those used in cloaking--at Louisiana Tech University in Ruston, Louisiana.An invisibility cloak will probably not be the first major accomplishment to come from the field of metamaterials．Other applications are just as excitin．In many labs，for example，scientists are working on building a hyperlens．A lens is a device——usually made of glass——that can change the direction of light waves．Lenses are used in microscopes and cameras to focus light，thus allowing a researcher to see small things or a photographer to capture image ofthings that are far away．A hyperlens，however，would be made of metamaterials．And since metamaterial s can do things with light that ordinary materials can't，the hyperlens would be a powerful t001．A hyperlens would allow researchers to see things at the smallest scale imaginable —as small as the wavelength of visible light．Genov points out that the science of metamaterials is driven by the imagination：If someone call think of an idea for a new behavior for fight，then the engineers can find a way to design a device using metamaterials．"We need people who can imagine," he says．Since 2006，many laboratories have been exploring other kinds of metamaterials that don't involve just visible light．In fact，scientists are finding that almost any kind of wave may respond to metamaterials．At the Polytechnic University of Valenciain Spain．Jose Sanchez-Dehesa is working with acoustics, or the science of sound．Just as an invisibility cloak shuffles waves of light，an "acoustic" cloak would shuffle waves of sound in a way that's not found in nature．In an orchestra hall, for example．an acoustic cloak could redirect the sound waves——so someone sitting behind a column would hear the same concert as the rest of the audience．without distortion．Sanchez-Dehesa，an engineer，recently showed that it's possible to build such an acoustic cloak，though he doubts we'11 see one any time soon．"In principle，it is possible," he says，but it might be impossible to make one, he adds．Other scientists are looking into ways to use larger metamaterials as shields around islands or oil rigs as protection from tsunamis．A tsunami is a giant．destructive wave．The metamaterial would redirect the tsunami around the rig or island．and the wavewould resume its ioumey on the other side without causing any harm．练习：1．What is true for metamaterials?They are nonexistent in nature．2．A hyperlens is a more powerful tool than a traditional lensas it can help scientists to see even the wavelengths of visible light．3．Scientists at the Polytechnic University of Valencia try to inventan acoustic cloak that can shuffle waves of sound．4．According to Sdnchez—Dehesa,it is possible to build an acoustic cloak in theory but far from．reality．5．What ways are some scientists looking into to protect the island and oil；rig from tsunamis? (Read the last paragraph．) Surround them with metamaterials as protective shields．A级阅读理解新增文章教材第四十五篇文章Some People Do Not Taste Salt Like Others Low—salt foods may be harder for some people to like than others，according to a study by a Penn State College of Agricultural Sciences food scientist．The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat．Those conclusions are important because recent，well—publicized efforts to reduce the salt content in food have left many people struggling to accept fare that simply does not taste as good to them as it does to others，pointed out John Hayes，assistant professor of food science，who was lead investigator 0n the study．Diets high in salt Can increase the risk of high blood pressure and stroke．That is why public health experts and food companies are working together on ways to help consumers lower salt intake through foodsthat are enjoyable to eat．This study increases understanding of salt preference and consumption．The research involved 87 carefully screened participants who sampled salty foods such as soup and chips，on multiple occasions，spread out over weeks．Test subjects were 45：men and 42 women, reportedly healthy，ranging in age from 20 t0 40 years．The sample was composed of individuals who were not actively modifying their dietary intake and did not smoke cigarettes．They rated the intensity of taste on a commonly used scientific scale，ranging from barely detectable to strongest sensation of any kind．“Most of us like the taste of salt．However，some individuals eat more salt，both because they like the taste of saltiness more，and also because it is needed to block other unpleasant tastes in food,”said Hayes. “Supertasters, people whoexperience tastes more intensely, consume more salt than nontasters do. Snack foods have saltiness as their primary flavor, and at least for these foods, more is better, so the supertasters seem to like them more.”However, supertasters also need higher levels of salt to block unpleasant bitter tastes in foods such as cheese，Hayes noted．“For example，cheese is a wonderful blend of dairy flavors from fermented milk，but also bitter tastes from ripening that are blocked by salt，” he said．“A supertaster finds low-salt cheese unpleasant because the bitterness is too pronounced6．”Hayes cited research done more than 75 years ago by a chemist named Fox and a geneticist named Blakeslee，showing that individuals differ in their ability to taste certain chemicals．As a result，Hayes explained，we know that a wide range in taste acuity exists，and this variation is as normal as variations in eye and hair color．“Some people，called supertasters，describe bitter compounds as being extremely bitter，while others，called nontasters，find these same bitter compounds to be tasteless or only weakly bitter．”he said．“Response to bitter compounds is one of many ways to identify biological differences in food preference because supertastin7 is not limited to bitterness．(476)1．In paragraph 2，John Hayes points out that many people accept low—salt tasteless food reluctantly2．The fourth paragraph describes briefly how to select subjects and what to do in the research．3. The article argues that supertasters1ike snack foods as saltiness is their primary flavor．4. Which of the following applies to supertasters in terms of bitter taste?They prefer high—salt cheese．whichtastes less bitter．5. What message do the last two paragraphs carry?Taste acuity is genetically determined．A级阅读理解新增文章教材第三十四篇文章Batteries Built by VirusesWhat do chicken pox，the common cold, the flu，and AIDS have in common? They’real disease caused by viruses，tiny microorganisms that can pass from person to person．It's no wonder1 that when most people think about viruses, finding ways t0 steer clear of viruses is what's on people's minds．Not everyone runs from the tiny disease carders, though．In Cambridge, Massachusetts, scientists have discovered that some viruses can be helpful in an unusual way．They are putting viruses to work, teaching them to build some of the world's smallest rechargeable batteries．Viruses and batteries may seem like an unusual pair，but they're not so strange forengineer Angela Belcher，who first came up with the idea．At the Massachusetts Institute of Technology (MIT) in Cambridge, she and her collaborators bring together different areas of science in new ways．In the case of the virus-built batteries, the scientists combine what they know about biology, technology and production techniques．Belcher's team includes Paula Hammond，who helps put together the tiny batteries, and Yet-Ming Chiang， an expert on how to store energy in the form of a battery．“We’re working on things we traditionally don’t associate with nature．” says Hammond．Many batteries are already pretty small．You can hold A．C and D batteries in your hand．The coin—like batteries that power watches are often smaller than a penny．However。

2011职称英语综合类新增文章2011年职称英语等级考试大纲没有变化，2010年考试大纲仍可沿用，2011年职称英语等级考试教材在2010年基础上进行了调整与修订，与2010年教材相比，2011年职称英语综合类教材在词汇选项、阅读判断、概括大意与完成句子、补全短文四大题型上都没有变换，只有阅读理解与完型填空两个题型上有部分变化，以下是具体变化：综合类教材变化内容：阅读理解：第八篇(C级)：The State of Marriage Today第三十八篇(B级)：Excessive Demands on Young People第四十七篇(A级)：Spoilt for Choice完型填空：第五篇(c级)：Why People Use Pseudonyms第十二篇(B级)：Sport or Spectacle?第十五篇(A级)：Life Expectancy in the Last Hundred Years综合类阅读“The Best W ay to Reduce Your Weight”被更新成了“Spoilt for Choice”In answer to the second question，the outlook may not be as pessimistic as it seems．While the rate of divorce has risen，the rate of couples marrying has never actually fallen very much，so marriage is still quite popular．In addition to this．many couples now cohabit and don’t bother to marry．These couples are effectively married，but they do not appear in either the marriage or divorce statistics．In fact．more than 50％Of first marriages survive．The statistics are deceptive because there is a higher number of divorces in second and third marriages than in first marriages．So is marriage really an outdated institution? The fact that most people still get married indicates that it isn’t．And it is also true that married couples have a healthier life than single people：they suffer less from stress and its consequences，such as heart problems，and married men generally consider themselves more contented than their single counterparts．Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!词汇：Divorce n．离婚Evidence n．证据，迹象Futurist n．未来主义者Explode v．激增，迅速扩大Predict v．预言，预料，预报Extramarital adj．婚外的Gloomy adj．阴暗的；令人沮丧的Institution n．制度，习俗Outlook n．展望，前景Pessimistic adj．悲观的Cohabit v．同居Effectively ad．实际上Statistics n．统计，统计资料Deceptive adj．迷惑的，骗人的Outdated adj．旧式的，过时的Indicate v．表明，暗示Consequence n．结果，后果Contented adj．满足的，满意的Counterpart n．对应的人(或物)注释：National Family Association：美国国家家庭联合会练习：1．Which is true about the problem of marriage in the United States today?A) Divorce leads to the breakup of the family．B) Half of the married couples get divorced：C) American people marry more than four times．D) More and more people are getting divorced．2．What does “this is no longer the case” in paragraph two mean?A) It is not necessary to get married any more．B) Women do not need a husband any longer．C) Women are not economically dependant any more．D) Many wives do well-paying jobs outside home now．3．Why may the outlook of marriage not be as gloomy as it appears?A) Many people still like to get married．B) The rate of divorce has actually decreased．C) Over 50％of the marriages continue to exist．D) The statistics of divorce is not quite true。

Ford has now announced it will do the same.Three years ago，the company introduced the Think City two-seater car and a golf cart called the THINK, or Think Neighbor6. It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1，700 carts have been sold so far in 2002."The bottom line is7 we don't believe that this is the future of environment transport for the mass market," Tim Holmes of Ford Europe said on Friday. "We feel we have given electric our best shot8. ”The Think City has a range of only about 53 miles and up to a six-hour battery recharge time. General Motors' EVI electric vehicle also had a limited range, of about 100 miles.The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota9 RA V4 EV vehicle costs over $42,000 in the US, compared with just $17,000 for the petrol version. Toyota and Nissan10 are now the only major auto manufacturers to produce electric vehicles."There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program11, and that is what we will be judging them on, ”Roger Higman，a senior transport campaigner at UK Friends of the Earth, told the Environment News Service.Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol-only engines, and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines12 on vehicle emissions13 in the US. However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler14 won a court injunction, delaying by two years Californian legislationrequiring car-makers to offer 100,000 zero-emission and other low-emission vehicles in the state by 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.词汇：hybrid /'haibrid/ n.杂种，混合物；adj.杂种mileage /'mailids/ n.英里数，英里里程的；混合的injunction/iidsAgkJ^n/n.命令；指令注释：1.

第二篇World Crude Oil Production May Peaka Decade Earlier Than Some PredictIn a finding that may speed efforts to conserve oil, scientists in Kuwait predict that world conventional crude oil production will peak in 2014. This prediction is almost a decade earlier than some other predictions．Their study is in ACS’Energy ＆Fuels1．Ibrahim Nashawi and colleagues point out that rapid growth in global oil consumption has sparked a growing interest in predicting "peak oil"．"Peak oil "is the point where oil production reaches a maximum and then declines. Scientists have developed several models to forecast this point, and some put the date at 2020 or later. One of the most famous forecast models is called the Hubbert model2. It assumes that global oil production will follow a bell shaped curve3. A related concept is that4 of "Peak Oil." The term "Peal Oil" indicates the moment in which world wide production Will peak, afterwards to start on irreversible decline．The Hubbert model accurately predicted that oil production would peak in the United States in 1970. The model has since gained in popularity and has been used to forecast oil production worldwide．However, recent studies show that the model is insufficient to account for5more complex oil production cycles of some countries．Those cycles can be heavily influenced by technology changes, politics, and other factors, the scientists say. The new study describes development of a new version of the Hubbert model that provides a more realistic and accurate oil production forecast．Using the new model, the scientists evaluated the oil production trends of 47 major oil-producing countries, which supply most of the world’s conventional crude oil6． They estimated that worldwide conventional crude oil production will peak in 2014, years earlier than anticipated. The scientists also showed that the world's oil reserves7 are being reduced at a rate of 2.1 percent a year. The new model could help inform energy-related decisions and public policy debate, they suggest.词汇：Conserve v．保护，保存crude oil原油spark v．闪耀；激发；鼓舞curve n．曲线irreversible adj．不可逆的，不可改变的insufficient adj.充分的，不足的注释：1．ACS' Energy & Fuels：ACS是American Chemical Society(美国化学学会)的缩写。

2．the Hubbert model：赫伯特模型是美国地质学家M．King Hubbert于1956年创建的，这是一个随时间增长的模型，Hubbert将其引入油气田开发，经推导使其成为一个可以预测油气田累积产量、瞬时产量、年产量和可采储量等多项开发指标的多功能预测模型。
3．a bell shaped curve：钟形曲线4．that of peak oil：that指代concept。
5．account for：说明，解释6．conventional crude oil：常规原油7．oil reserves：石油储量。
通常使用复数形式reserves。
练习：1．Which of the following is closest in meaning to the word "sparked" appearing in paragraph 2?A．flashedB．stimulatedC．changedD．ended2．The term "a bell shaped curve" appearing in paragraph 2 indicates that global oil production willA．take the shape of a flat curve．B．keep growing．C．keep declining．D．start to decline after global oil production peaks．3．Which of the following is NOT true of the Hubbert model?A．It successfully predicted that oil production peaked in the U．S．in l 970．B．It has been used to predict oil production in many countries．C．It is insufficient to explain oil production cycles in some countries．D．It provides a very realistic and accurate oil production．4．What is the major achievement of the new study mentioned in the last paragraph? A．It predicts global oil production will peak in 2014．B．It predicts oil production will decline in 47 countries．C．It confirms further the effectiveness of the Hubbert model．D．It discovers a new trend of Worldwide oil production．5．Who develop the new version of the Hubbert model?A．American scientists．B．Kuwaiti scientists．C．British scientists．D．Scientists of 47 major oil-producing countries．答案与题解：1．B spark一词做及物动词使用时有"发动"、"激发"的意思，在此意为stimulated，即"引发"，这个句子的意思是：全球石油消费的快速增长已引发了对"石油峰值"预测的兴趣。
2．D此句接下来的句子中所提到的a related concept即是与a bell shaped curve相关的概念，也就是说，接下来的这个句子对a bell shaped curve做了解释，即世界石油生产达到最大峰值后将下降。
