职称英语理工类新增
写在最前面的关于30分题+15分1. +表示A级文章；*表示B即文章；其他为C级文章，考哪一级就看哪一级的内容，别的级别的题目完全不用看。
2. 每个级别新增阅读理解2篇完型填空2篇（今年以前完形填空只新增一篇），考试的时候，这两篇阅读理解必考一篇，文章完全一样，但是问题及答案不一定完全一样，所以仅仅记住答案是不可靠的，一定要结合后面的翻译把这篇文章看懂。
那么这里5道题目15分必定能拿到。
然后完型填空，先说今年以前，只新增一篇完型填空，这篇完型填空必考，只是留空的位置不会完全一样，大约有40%左右的留空位置是一样，所以光背答案是没得用的，一定要把文章看熟。
当然今年由于每个级别新增了2篇完型填空，那么考试的时候肯定也是2选1考一篇。
这里15道题15分也很容易能拿到。
3. 词汇有15道题，替换同义词，找本字典翻翻，这15分也不难，至少12分能拿到吧。
其他的题能拿多少分就看各位的英语底子了。
做最坏的打算，剩下的题目还有55分，按瞎蒙25%的概率能拿到13.75分，加上前面的45分大约也有58分左右，所以要完全靠瞎蒙的朋友考试前多扶扶老奶奶过马路，多积累点人品吧。
4. 以上只是投机取巧的方法，各位有时间的话还是花点时间复习下，但是考前一定要把新增的题目掌握好，就算英语底子好的朋友也起码可以节约不少考试时间。
5. 本人职称英语A\B\C级都是这样考过的，每年的规律都是一样的。
从客观角度说，每年的职称英语考试书都不便宜，新增的内容也不多，如果新增的东西里面没有价值，那么那本书还有谁买？那本书可是考试中心出的，亲！最后，祝大家考试顺利！2012年职称英语理工类新增文章阅读理解（6篇）……………………3页第六篇 Making Light of1 Sleep第十九篇 Graphene's Superstrength1*第三＋八篇 "Life Form Found" on Saturn's Titan*第四十篇 Teaching Math, Teaching Anxiety+第四＋五篇 Teaching Math, Teaching Anxiety+第四十六篇Ants Have Big Impact on Environment as "Ecosystem Engineers"完形填空（6篇）……………………20页第三篇 Germs on Banknotes第十篇 Chicken Soup for the Soul：Comfort Food Fights Loneliness *第十一篇 Climate Change Poses Major Risks for Unprepared Cities*第十二篇 Free Statins With Fast Food Could Neutralize Heart Risk+第十三篇 Solar Power without Solar Cells+第十五篇“Liquefaction” Key to Much of Japanese Earthquake Damage注：1、+表示A级文章；*表示B即文章；其他为C级文章；2、阅读理解，请参见第3页；完形填空，请参见第20页；3、2012年词汇部分与2011年教材相比未作任何变化。

M Climate Change Poses Major Risks for Unprepared Cities A new examination of urban policies has been carried out recently by Patricia Romero Lankao. She is a sociologist specializing in climate change and urban development. She warns that many of the world’s fast -growing urban areas, especially in developing countries, will likely1 suffer from the impacts of changing climate. Her work also concludes that most cities are failing to reduce emissions of carbon dioxide and other greenhouse 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 Romero Lankao. “But too few cities are developing effective strategies to protect their residents. ” Cities are major sources of greenhouse gases. And urban populations are likely to be among those most severely affected by future climate change. Lankao’s findings3 highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term benefits The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential threats associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat 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 increase existing levels of air pollution, causing widespread health problems. Poorer neighborhoods that may 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 substandard housing without access to reliable drinking water, roads and basic services. Local governments,therefore,should take measures to protect their residents. “Unfortunately, they tend to move towards rhetoric rather than meaningful responses,” Romero Lankao writes. “They don’t impose construction standards that could reduce heating and air conditioning needs. They don’t emphasize mass transit and reduce automobile, use. In fact, many local governments are taking a hands-off approach.” Thus, she urges them to change their idle policies and to take strong steps to prevent the harmful effects of’ climate change on cities. Free Statins With Fast Food Could Neutralize Heart Risk Fast food outlets could provide statin drugs free of charge so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London suggest in a new study. Statins reduce the amount of unhealthy “LDL ” cholesterol in the blood. A wealth of trial data4 has proven them to be highly effective at lowering a person ’s heart attack 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 enough to offset the increase in heart attack risk from 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 all of the unhealthy effects of cheeseburgers and French fries. It ’s better to avoid fatty food altogeth er. But we’ve worked out that in terms of your possibility of having a heart attack, taking astatin can reduce your risk to more or less the same degree as a fast food meal increases it. ”It ’s ironic that people are free to take as many unhealthy condiments in fast food outlets as they 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 provided free of charge. It would cost less than 5 pence per customer —— not much different to a sachet of sugar, “ Dr Francis said.When people engage in risky behaviours likedriving or smoking, they ’re encouraged to take measures that lower their risk, like wearing a seatbelt or choosing cigarettes with filters. Taking a stain is a rational way of lowering some of the risks of eating a fatty meal.Better Solar Energy Systems: More Heat, More LightSolar photovoltaic thermal energy systems, or PVTs, generate both heat and electricity, but until now they haven’t been very good at the heat-generating part compared to a stand-alone solar thermal collector. That’s because they operate at low temperatures to cool crystalline silicon solar cells, which lets the silicon generate more electricity but isn’t a very efficient way to gather heat. That ’s a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And it ，s also a space problem ：photovoltaic cells can take up all the space on the roof, leaving little room for thermal applications. In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a solution in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Girotra from ThinSilicon in California and Michael Pathak and Stephen Harrison from Queen’s Universi ty, Canada." Most solar panels are made with crystalline silicon ， but you can also make solar cells out of amorphous silicon,commonly known as thin-film silicon. They don ’t create as much electricity, but they are lighter, flexible, and cheaper. And, because they require much less silicon, they have a greener footprint. Unfortunately ，thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.M “That means that their efficiency drops when youexpose them to light —pretty much the worstpossible effect for a solar cell,”Pearce explains，which is one of the reasons thin- film solar panelsmake up only a small fraction of the market.However, Pearce and his team found a way toengineer around the Staebler-Wronski effect byincorporating thin-film silicon in a new tpye ofPVT. You don’t have to cool down thin-filmsilicon to make it work. In fact，Pearce’s groupdiscovered that by heating it to solar-thermaloperating temperatures，near the boiling point ofwater, they could make thicker cells that largelyovercame the Staebler-Wronski effect. When theyapplied the thin-film silicon directly to a solarthermal energy collector, they also found that bybaking the cell once a day，they boosted the solarcell’s electrical efficiency by over 10 percent.Sharks Perform a Service for Earth’s WatersyIt is hard to get people to think of sharks asanything but a deadly enemy. They are thought toattack people frequently. But these fish perform avaluable ser vice for earth’s waters and for humanbeings. Yet business and sport fishing3 arethreatening their existence. Some sharks are at riskof disappearing from earth.Warm weather may influence both fish and sharkactivity. Many fish swim near coastal areasbecause of their warm waters. Experts say sharksmay follow the fish into the same areas,wherepeople also swim. In fact, most sharks do notpurposely charge at or bite humans. They arethought to mistake a person for a sea animal, suchas a seal or sea lion. That is why people should notswim in the ocean when the sun goes down orcomes up. Those are the times when sharks arelooking for food. Experts also say that brightcolors and shiny jewelry may cause sharks toattack.A shark has an extremely good sense of smell4. Itcan find small amounts of substances in water,such as blood, body liquids and chemicalsproduced by animals. These powerful senses helpsharks find their food. Sharks eat fish, anyother sharks, and plants that live in the ocean.Medical researchers want to learn more about theshark’s body defense and immune systems againstdisease. Researchers know that sharks recoverquickly from injuries. They study the shark inhopes of finding a way to fight human disease.Sharks are impo rtant for the world’s oceans. Theyeat injured and diseased fish. Their huntingactivities mean that the numbers of other fish inocean waters do not become too great. Thisprotects the plants and other forms of life that existin the oceans.“Liquefaction” Key to Much of JapaneseEarthquake DamageThe massive subduction zone earthquake in Japancaused a significant level of soil “liquefaction” thathas surprised researchers with its widespreadseverity, a new analysis shows.We’ve seen localized examples o f soil liquefactionas extreme as this before, but the distance andextent of damage in Japan were unusually severe,”said Scott Ashford, a professor of geotechnicalengineering at Oregon State University. “Entirestructures were tilted and sinking into thesediments,” Ashford said. “The shifts in soildestroyed water, drain and gas pipelines, cripplingthe utilities and Infrastructure these communitiesneed to function. We saw some places that sank asmuch as four feet. ”Some degree of soil liquefaction is common inalmost any major earthquake. It’s a phenomenon inwhich soils soaked with water, particularly recentsediments or sand, can lose much of their strengthand flow during an earthquake. This can allowstructures to shift or sink or collapse.But most earthquakes are much shorter than therecent event in Japan, Ashford said. The length ofthe Japanese earthquake, as much as five minutes,may force researchers to reconsider the extent ofliquefaction damage possibly occurring insituations such as this.“With such a long-lasting earthquake, we sawhow structures that might have been okay after 30seconds just continued to sink and tilt as theshaking continued for several more minutes,” hesaid. “And it was clear that younger sediments, andespecially areas built on recently filled ground, aremuch more vulnerable.”The data provided by analyzing the Japaneseearthquake, researchers said, should make itpossible to improve the understanding of this soilphenomenon and better prepare for it in the future.Ashford said it was critical for the team to collectthe information quickly,before damage wasremoved in the recovery efforts.There’s no doubt that we’ll learn things from whathappened in Japan that will help us to reduce risksin other similar events,” Ashford said. “Futureconstruction in some places may make more use oftechniques known to reduce liquefaction, such asbetter compaction to make soils dense, or use ofreinforcing stone columns.”Ashford pointed out that northern California haveyounger soils vulnerable to liquefaction –on thecoast, near river deposits or in areas with filledground. The “young” sediments, in geologic terms,may be those deposited within the past 10,000years or more. In Oregon, for instance, thatdescribes much of downtown Portland, thePortland International Airport and other cities.Anything near a river and old flood plains is asuspect, and the Oregon Department ofTransportation has already concluded that 1100bridges in the state are at risk from an earthquake.Fewer than 15 percent of them have beenreinforced to prevent collapse. Japan has sufferedtremendous losses in the March 11 earthquake, butJapanese construction standards helped preventmany buildings from collapse – even as they tiltedand sank into the ground.Batteries Built by Viruses病毒电池What do chicken pox, the common coldM水痘、普通感冒、流感和艾滋病有哪些相似之处呢？这些都是由病毒引起的疾病。

抢先直击2015职称英语教材新变化-综合类
抢先直击2015职称英语教材新变化新东方在线2015年职称英语教材在千呼万唤中姗姗来迟，相比于2014年11月初的教材发布时间，今年的教材发布整整迟了一个多月，这对于复习时间短暂而集中，英语基础薄弱，历来依赖押题通关的职称学员来说，无疑是巨大的煎熬。
新东方在线职称英语教研团队也和各位考生一样，怀着焦虑忐忑的心情，等待着新教材的公布。
针对2015年教材小新总结了以下几点与广大焦虑中的考生们分享，同时针对大家的问题给出一些建议。
一、新教材的变化新教材的确有变化，但是真真的变化不大。
变化主要出现在了阅读判断、阅读理解和补全短文三个题型的教材篇章上。
对阅读判断中C级别的第三篇文章进行了替换，旧版中的“TV Game Shows电视“智力竞赛”表演”被删掉，新版换成了“Across the Desert穿越沙漠”，其他两个级别的文章没有改动。
阅读理解有两篇文章发生了变化，旧版中的C级第六篇“TV Shows and Long Bus Trips看电视与长途汽车旅行”，新版中换成了“Native American Pottery 美国本土陶器”；旧版中的B级第二十四篇“Clone Farm克隆农场”，新版被换为“The Romance of Arthur亚瑟传奇”。
对补全短文A、B、C三个级别分别有一篇文章进行了替换，C级第三篇“Are Online Friends Real Friends?网友算真正的朋友吗？”换成了“The Value of Tears眼泪的价值”，B级第九篇“第九篇Heat Is Killer 高温杀手”换为“Style, Not Fashion格调，不等于时尚”，A级第十二篇“Obesity Causes Global Warming肥胖导致全球变暖”被换为“Men Smell of Cheese and Women of onions”。
整本教材共有6篇文章做了新增，过去大家特别关注的阅读理解只有2篇新增，其他都没有变化，这与去年的情形相似。

理工A补全短文新增文章：+第十三篇 Affectionate AndroidsComputers are now powerful enough to allow the age of humanoid robots to dawn1. And it won’t be long before we will see realistic cyber companions, complete with skin, dexterity, and intelligence. They will be programmed to tend to your every need.Will we ever want to marry robots? Artificial intelligence researcher David Levy has published a book claiming human-robot relationships will become popular in the next few decades. ____1____Will humans really be able to form deep emotional attachments to machines? It will, in fact, be relatively easy to form these strong attachments because the human mind loves to anthropomorphize: to give human attributes to other creatures—even objects.For example, researchers in San Diego recently put a small humanoid robot in with a toddler playgroup for several months. ____2____ The children ended up treating it as a fellow toddler. When it lay down because its batteries were flat，the kids even covered it with a blanket.In a few decades, when humanoid robots with plastic skin look and feel very real, will people want to form relationships with them? What if the bots could hold a conversation? And be programmed to be the perfect companions—soul mates, even? ____3____ And like those toddlers in the experiment, they will be very accepting of them.The next question, then, is whether there is anything wrong with having an emotional relationship with a machine. Even today there are people who form deep attachments to their pets and use them as substitutes for friends or even children. Few consider that unethical.____4____ For those who always seem to end up marrying the wrong man or woman, a robotic Mr. or Ms. Right could be mighty tempting. As the father of artificial intelligence, Marvin Minsky, put it when asked about the ethics of lonely older people forming close relationships with robots: “If a robot had all the virtues of a person and was smarter and more understanding, why would the elderly bother talking to other grumpy old people?”A robot could be programmed to be as dumb or smart, as independent or subservient, as an owner desired. And that’s the big disadvantage. Having the perfect robot partner will damage the ability to form equal ly deep human-human relationships. People will always seem imperfect in comparison. When you’re behaving badly, a good friend will tell you. ____5____People in relationships have to learn to adapt to each other: to enjoy their common interests and to deal with their differences. It makes us richer, stronger, and wiser. A robot companion will be perfect at the start. However, there will be nothing to move the relationship to grow to greater heights.词汇：affectionate adj. 深情的dexterity n. 灵巧，敏捷anthropomorphize v. 赋于人性，人格化grumpy adj. 脾气暴躁的cyber adj. 计算机的tend v. 照料bot n. 机器人subservient adj. 屈从的，奉承的注释：1．Computers are now powerful enough to allow the age of humanoid robots to dawn：计算机技术已经足够成熟，能够支持人形机器人的诞生和普及，进入人形机器人的时代。
2015理工A级职称英语新增文章(费尽心血整理版)
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 objects2 in 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 takes pictures of features that give off infrared radiation6.Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of light7 that 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. Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras don't see them,and neither do the eyes of human beings. Although invisible to the eye,longer infrared radiation can be detected as warmth by the skin.That's a key idea to why WISE will be able to see things other telescopes can't. Not everything in the universe shows up in visible light. Asteroids,for example,are giant rocks that float through space 一but they absorb most of the light that reaches them. They don't reflect light,so they're difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them. During its mission WISE will take pictures of hundreds of thousands of asteroids.Brown dwarfs8 are another kind of deep-space object that will show up in WISE's pictures. These objects are"failed" stars 一which means they are not massive enough to jump start9 the same kind of reactions that power stars such as the sun. Instead,brown dwarfs simply shrink and cool down. They're so dim that they're almost impossible to see with visible light, but in the infrared spe ctrum they glow.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。

2015职称英语理工类新增5篇理工C阅读理解新增文章第九篇An Essential Scientific ProcessAll life on the earth depends upon green plants. Using sunlight, the plants produce their own food. Then animals feed upon the plants. They take in the nutrients the plants have made and stored. But that’s not all. Sunlight also helps a plant produce oxygen. Some of the oxygen is used by the plant, but a plant usually produces more oxygen than it uses. The excess oxygen is necessary for animals and other organisms to live.The process of changing light into food and oxygen is called photosynthesis. Besides light energy from the sun, plants also use water and carbon dioxide. The water gets to the plant through its roots. The carbon dioxide enters the leaves through tiny openings called stomata. The carbon dioxide travels to chloroplasts, special cells in the bodies of green plants. This is where photosynthesis takes place. Chloroplasts contain the chlorophylls that give plants their green color. The chlorophylls are the molecules that trap light energy. The trapped light energy changes water and carbon dioxide to produce oxygen and a simple sugar called glucose.Carbon dioxide and oxygen move into and out of the stomata. Water vapor also moves out of the stomata. More than 90 percent of water a plant takes in through its roots escapes through the stomata. During the daytime, the stomata of most plants are open. This allows carbon dioxide to enter the leaves for photosynthesis. As night falls, carbon dioxide is not needed. The stomata of most plants close. Water loss stops.If photosynthesis ceased, there would be little food or other organic matter on the earth. Most organisms would disappear. The earth’s atmosphere would no longer contain oxygen. Photosynthesis is essential for life on our planet.词汇：nutrient n.营养物organism n.生物体，有机体carbon dioxide n.二氧化碳chloroplast n.叶绿体molecule n.分子vapor n.水蒸气oxygen n.氧气photosynthesis n.光合作用chlorophyll n.叶绿素glucose n.葡萄糖cease v.停止注释：1．Then animals feed upon the plants.动物以植物为食。
练习：1．In the first paragraph，the word “excess” meansA heavy.B extra.C green.D liquid.2．Which of the following does not move through a plant’s stomata?A Carbon dioxide.B Water vapor.C Oxygen.D Food.3．In the title, the term Essential Scientific Process refers toA photosynthesis.B the formation of glucose.C global warming.D water getting to the roots of plants.4．This passage is primarily developed byA explaining a process.B telling a story.C comparing and contrasting.D convincing the reader of plants’ importance.5．Another good title for this passage would beA Oxygen and Carbon Dioxide.B Plants and Their Roots.C How Photosynthesis Works.D Why Our Earth Needs Water.答案与题解：1．B前文讲到，植物产生的氧气一部分被植物自身消耗了，但植物消耗的氧气量远小于它们产生的氧气，因此可以推测这句话的意思应该是剩余的氧气对于动物以及其他生物体的生存是至关重要的。
excess在句中的意思是“超额的”，与extra“额外的”意思相近。
2．D从第三段的第一、二句得知，二氧化碳、氧气和水蒸气都能从气孔中通过，唯一一个没有提到的是food“养分、食物”，因此该题选D项。
3．A文章通篇都在讲Photosynthesis，即光合作頌钠作用和重要性，文章结尾又重申了Photosynthesis is essential for life on our planet，因此选A项。
B项是光合作用的一个部分，C、D项则毫不相干。
4．A文章先是介绍了进行光合作用所需的原料和组织，又介绍了光合作用的过程，因此整个逻辑应该是解释过程，而不是讲故事或比较对比。
D项是“向读者说明植物的重要性”，这确实是文章的一个目的，但不是文章的组织方式。
5．C文章的主题是光合作用的基本原理，因此选项C。
A、B项在文中有提及，但不是主旨，D项与本文无关。

But Opportunity has continued to collect and analyze Martian soil and rocks.During its mission, Opportunity has captured, and sent back to Earth, some 187,000 panoramic and microscopic images of Mars with its cameras. ____4____MARA THON ROVERThe rover doesn’t seem to be ready to stop just yet. If Opportunity can continue on, it will reach another major investigation site when its odometer hits 26.2 miles. ____5____Researchers believe that clay minerals exposed near Marathon V alley could hold clues to Mars’s ancient environment1. Opportunity’s continuing travels will also help researchers as they plan for an eventual human mission to the Red Planet.词汇：Mars rover n. 火星车panoramic adj. 全景的odometer n. 里程计rack up v. 积累microscopic adj. 微观的注释：1．could hold clues to Mars’s ancient environment：含有与火星早期环境有关的线索。
