第十一篇When Our Eyes Serve Our Stomach（当我们的视觉服务于我们的胃口）我们的五官不仅仅让我们感知世界，五官感受还受大脑活动的影响。

一项新的研究发现，饥饿的人比刚刚用过餐的人更能清晰地看到与食物相关的词汇。

数十年来，心里学家已经知道我们的心里活动直接影响到我们的视觉。

例如，贫穷的孩子看到的硬币比实际的要大，饥饿的人看到食物的图片更明亮。

法国的尼斯.索菲亚.安提波利斯大学试图调查这一现象。

发生这种现象是在看到事物的当时，还是稍后延迟到大脑高级思维活动已经介入。

雷戴尔招募了42个健康指数正常的学生作为测试者。

在测试当天，每个学生被告诉在中午到达实验室，这时距上一次用餐时间由3~4小时。

等他们到达实验室时被告知实验时间有延迟。

一半学生被告知十分钟后回来，另一半学生给1个小时的实际先去吃午饭。

所以当实验室一半学生是饥饿状态，而另一半学生刚刚吃过饭。

这个实验，就是要求参与者看着电脑屏幕。

屏幕上的80个单词以1/300秒的频率闪动。

由于字体太小，被测试者只能凭感觉捕捉到字形。

1/4的字是与食物相关的。

每闪动一个单词，被测试者要回答字体的亮度并选择看到的是哪类词：一类是与食物相关的，比如蛋糕；一类是中性词，比如船。

由于每个单词闪动的太快以至于被测试者根本看不清楚词是什么。

饥饿的人看到与食物有关的词更明亮，且能更好地辨认出与食物有关的词。

由于每个词的闪动太快，其实那些被试者根本不会确切地看到什么，这就说明：他们只是感觉不同，根本没经过思考。

雷戴尔给出了这样的解释。

雷戴尔说：“这对我来说是一件伟大的事情。

人类可以真正感知到自身的需要或者为之奋斗的目标。

该实验使我了解这样的事实，即我们的大脑是受我们的动机和需要所支配的。

”1第一段提到的新的研究发现了什么？A 饥饿的人看每一个单词都比普通的人更清晰B 饥饿的人一直都在想与食物相关的词C 饥饿的人比饱腹的人对食物相关的词汇更敏感D 饥饿的人不是低思维的人2 为什么在测试的那天测试有个延迟？A 因为饥饿的人需要时间吃饭B 因为雷戴尔想要形成两组测试人群，饥饿的和饱腹的人C 因为中午对任何测试都不是合适的时间D 因为雷戴尔需要时间选取身体合格的测试者3 作者想要告诉我们什么？A 人类的五官不仅仅让我们感知世界B 我们的感知怎么受我们的思维支配C 我们大脑的活动受到我们的动机和需求的支配D 思维保证我们感知功能的正常运行4 实验的结果表明？A 80个单词在屏幕上闪的太快以至于参与者不能真正感知它们B 饥饿的人更善于认识中性词C 吃过饭的人更善于识别与食物相关的词汇D 参与者仅仅接受它们需要或者他们渴望的词汇5 从这篇文章我们能推知？A 42个参与者对于一个严格的实验来说数目太少B 用饥饿与不饥饿的参与者得出的实验结果是不可靠的C 我们的思维过程独立于我们的感知D 人类可以感知他们所需要的东西在大脑思维没有介入的情况下第十二篇Florida Hit by Cold Air Mass（佛罗里达遭受冷空气袭击）2003年1月，美国东部2/3的地区处于强冷空气团的控制下，强冷空气团给佛罗里达的柑橘树造成了威胁，同时也使北部的港口处于被冻结状态。

2014年职称英语卫生类新增新增ABC级文章及答案详解第二部分阅读判断第九篇What Is a Dream?（B级）For centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning. Others，however，think that dreams are an important part of our lives. In fact, many experts believe that dreams can tell us about a person‟s mind and emotions.Before modern times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way.The Austrian psychologist, Sigmund Freud1，was probably the first person to study dreams scientifically. In his famous book, The interpretation of Dreams (1900), Freud wrote that dreams are an expression of a person‟s wishes. He believed that dreams allow people to express the feelings, thoughts, and fears that they are afraid to express in real life.The Swiss psychiatrist Carl Jung2was once a student of Freud‟s. Jung，however，had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. He thought people could learn more about themselves by thinking about their dreams. For example, people who dream about falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves.Modern-day psychologists continue to develop theories about dreams. For example, psychologist William Domhoff from the University of California, Santa Cruz，believes that dreams are tightly linked to a person‟s daily life, thoughts, and behavior. A criminal, for example, might dream about crime.Domhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults. According to Domhoff, dreaming is a mental skill that needs time to develop.He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. For example, the people in men‟s dreams are often other men, and the dreams often involve fighting. This is not true of women‟s dreams.3Domhoff found this gender difference in the dreams of people from 11 cultures around the world, including both modern and traditional ones.Can dreams help us understand ourselves? Psychologists continue to try to answer this question in different ways. However, one thing they agree on this: If you dream that something terrible is going to occur, you shouldn‟t panic. The dream may have meaning, but it does not mean that some terrible event will actually take place. It‟s important to remember that the world of dreams is not the real world.词汇：psychologist / saɪ'kɔlədʒɪst / n．心理学家psychiatrist /sai' kaiətrɪst/ n．精神病学家(医生) Austrian / 'ɔstrɪən / adj．奥地利的gender / 'dʒendə / n．性别注释：1．Sigmund Freud西格蒙德•弗洛伊德（1856—1939)，犹太人，奥地利精神病医生及精神分析学家。

2014年职称英语（卫生类）新增文章译文及解析——阅读理解第十六篇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 to most 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 toxins.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-feed3for a month when they were34months old—equivalent to about70human years.The researchers checked the activity of11,000genes from the mouse livers,and found that46changed with age in the normally fed mice.The changes were associated with things like inflammation and free radical production一probably bad news for mouse health.In the mice that had dieted all their lives,27of those46genes continued to behave like young genes.But the most surprising finding was that the mice that only started dieting in old age also benefited from70per cent of these gene changes."This is the first indication that these effects kick in 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 it.“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,Lifespan Genetics in California,is looking for drugs that have the effects of calorie restriction.词汇：meager adj.不足的youthful adj.有青春活力的vigor n.精力，活力metabolize vt.使（一种物质）进入新陈代谢过程genetic adj.基因的rejuvenation n.恢复活力，返老还童注释：1.hang on to：继续保留。

A级—理工类第一部分阅读理解Black Holes Trigger Stars to Self-DestructScientists have long understood that super massive black holes weighing millions or billions of suns can tear apart stars that come too close. The black hole's gravity pulls harder on the nearest part of the star, an imbalance that pulls the star apart over a period of minutes or hours, once it gets close enough.Scientists say this uneven pulling is not the only hazard facing the star. The strain of these unbalanced forces can also trigger a nuclear explosion powerful enough to destroy the star from within. Matthieu Brassart and Jean-Pierre Luminet of the Observatoire de Paris in Meudon, France, carried out computer simulations of the final moments of such an unfortunate star's life, as it veered towards a super massive black hole.When the star gets close enough, the uneven forces flatten it into a pancake shape. Some previous studies had suggested this flattening would increase the density and temperature inside the star enough to trigger intense nuclear reactions that would tear it apart. But other studies had suggested that the picture would be complicated by shock waves generated during the flattening process and that no nuclear explosion should occur.The new simulations investigated the effects of shock waves in detail, and found that even when their effects are included, the conditions favor a nuclear explosion. "There will be an explosion of the star —it will be completely destroyed," Brassart says. Although the explosion obliterates the star, it saves some of the star's matter from being devoured by the black hole. The explosion is powerful enough to hurl much of the star's matter out of the black hole's reach, he says.The devouring of stars by black holes may already have been observed, although at a much later stage. It is thought that several months after the event that rips the star apart, its matter starts swirling into the hole itself. It heats up as it does so, releasing ultraviolet light and X-rays.If stars disrupted near black holes really do explode, then they could in principle allow these events to be detected at a much earlier stage, says Jules Halpern of Columbia University in New York, US. "It may make it possible to see the disruption of that star immediately if it gets hot enough," he says.Brassart agrees. "Perhaps it can be observed in the X-rays and gamma rays, but it's something that needs to be more studied," he says. Supernova researcher Chris Fryer of the Los Alamos National Laboratory inLos Alamos, New Mexico, US , says the deaths of these stars are difficult to simulate, and he is not sure whether the researchers have proven their Case that they explode in the process.练习：1. Something destructive could happen to a star that gets too close to ablack hole. Which of the following destructive statements is NOT mentioned in the passage?A The black hole could tear apart the star.B The black hole could trigger a nuclear explosion in the star.C The black hole could dwindle its size considerably,D The black hole could devour the star.2. According to the third paragraph, researchers differed from each other in the problem ofA whether nuclear reaction would occur.B whether the stars would increase its density and temperature.C whether shock waves would occur.D whether the uneven forces would flatten the stars.3. According to the fourth paragraph, which of the following is NOT true?A No nuclear explosion would be triggered inside the star.B The star would be destroyed completely.C Much of the star's matter thrown by the explosion would be beyond the black hole's reach.D The black hole would completely devour the star.4. What will happen several months after the explosion of the star?A The star's matter will move further away from by the black hole.B The black hole's matter will heat up.C The torn star's matter will swirl into the black hole.D The black hole's matter will release ultraviolet light and X-rays.5. According to the context, the word "disruption" in Paragraph: 6 meansA "Confusion. "B "Tearing apart."C "Interruption. "D "Flattening. "Too Little for Global WarmingOil and gas will run out1 too fast for doomsday global warming scenarios to materialize, according to a controversial new analysis presented this week at the University of Uppsala in Sweden. The authors warn that all the fuel will be burnt before there is enough carbon dioxide in the atmosphere to realize predictions of melting ice caps and searing temperatures. Defending their predictions, scientists from the Intergovernmental Panel on Climate Change saythey considered a range of estimates of oil and gas reserves, and point out that coal-burning could easily make up the shortfall. But all agree that burning coal would be even worse for the planet.The IPCC's predictions of global meltdown pushed forward the 1997 Kyoto Protocol, an agreement obliging signatory nations to cut CO2 emissions. The IPCC considered a range of future scenarios, from unlimited burning of fossil-fuels to a fast transition towards greener energy sources. But geologists Anders Sivertsson, Kjell Aleldett and Colin Campbell of Uppsala University say there is not enough oil and gas left even the most conservative of the 40 IPCC scenarios to come to pass.Although estimates of oil and gas reserves vary widely, the researchers are part of a growing group of experts who believe that oil supplies will peak as soon as 2010, and gas soon after. Their analysis suggests that oil and gas reserves combined amount to the equivalent of about 3,500 billion barrels of oil considerably less than the 5,000 billion barrels estimated in the most optimistic model envisaged by the IPCC. Even the average forecast of about 8,000 billion barrels is more than twice the Swedish estimate of the world's remaining reserves. Nebojsa Nakicenovic, an energy economist at the University of Vienna, Austria who headed the 80-strong IPCC team that produced the forecasts, says the panel's work still stands. He says they factored in a much broader and internationally accepted range of oil and gas estimates than the "conservative" Swedes.Even if oil and gas run out, "there's a huge amount of coal underground that could be exploited", he says that burning coal could make the IPCC scenarios come true, but points out that such a switch would be disastrous. Coal is dirtier than oil and gas and produces more CO2for each unit of energy, as well as releasing large amounts of particulates. He says the latest analysis is a "shot across the bows'' for policy makers.练习：1. What do the authors of the new analysis presented at the University of Uppsala intend to say?A) The burning of coal will accelerate the arrival of Earth's doomsday.B) The oil reserves are big enough to materialize the doomsday scenarios.C) Melting ice caps and searing temperatures exist only in science fiction.D) Oil and gas will run out so fast that Earth's doomsday will never materialize.2. Nations that signed the Kyoto Protocol agree toA) pay attention to global meltdown. B) cut CO2 emissions.C) use more green energy. D) stop using fossil fuels.3. What are the estimates of the world's oil and gas reserves?A) 4,000 billion barrels by the average forecast. B) 8,000 billion barrels estimated by the Swedes.C) 3,500 barrels envisaged by IPCC. D) 3,500 billion by a growing number of scientists.4. Which of the following about Nebojsa Nakicenovic is true?A) He thinks fossil fuels are as dirty as oil and gas.B) He thinks green fuels will replace oil and gas eventually.C) He thinks IPCC's view on the world's oil reserves is too optimistic.D) He thinks that IPCC's estimates are more optimistic than the Swedes.5. Which of the following is the near explanation of Nakicenovic's assertionthat "... such a switch would be disastrous ..."?A) The IPCC scenarios would come true because burning coal will emit largeramounts of CO2.B) A switch to burning coal would produce disastrous environmental problems.C) Oil and gas to replace coal as fuel would speed up the process of global warming.D) A switch from the IPCC scenarios to the policymakers' ones would be disastrous.U.S. Scientists Confirm Water on MarsNASA scientists said that Mars was covered once by vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life. Laboratory tests aboard NASA's Phoenix Mars Lander have identified water in a soil sample. The lander's robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples."We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. "This is the first time Martian water has been touched and tasted."The robotic arm is a critical part of the Phoenix Mars mission. It is needed to trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze what Mars is made of, what its water is like, and whether it is or has ever been a possible habitat for life.The soil sample came from a trench approximately 2 inches deep. When the robotic arm first reached that depth, it hit a hard layer of frozen soil. Two attempts to deliver samples of icy soil on days when fresh material was exposed were foiled when the samples became stuck inside the scoop. Most of the material in Wednesday's sample had been exposed to the air for two days, letting some of the water in the sample vaporize away and making the soil easier to handle."Mars is giving us some surprises," said Phoenix principal investigator Peter Smith of the University of Arizona. "We're excited because surprises are where discoveries come from. One surprise is how the soil is behaving. The ice-rich layers stick to the scoop when poised in the sun above the deck, different from what we expected, from all the Mars simulation testing we've done so far."Since landing on May 25, Phoenix has been studying soil with a chemistry lab, TEGA, a microscope, a conductivity probe and cameras. The science team is trying to determine whether the water ice ever thaws enough to be available for biology and if carbon-containing chemicals and other raw materials for life are present. The mission is examining the sky as well as the ground. A Canadian instrument is using a laser beam to study dust and clouds overhead."It's a 30-watt light bulb giving us a laser show on Mars," said Victoria Hipkin of the Canadian Space Agency.A full-circle, color panorama of Phoenix's surroundings also has been completed by the spacecraft."The details and patterns we see in the ground show an ice-dominated terrain as far as the eye can see," said Mark Lemmon of Texas A & M University, lead scientist for Phoenix's Surface Stereo Imager camera. "They help us plan measurements we're making within reach of the robotic arm and interpret those measurements on a wider scale."练习：1. What was discovered by NASA's Phoenix Mars Lander on Mars?A Vast lakes.B Flowing rivers.C Water in a soil sample.D Living things.2. Why did the first two attempts to deliver samples fail?A The sample vaporized away.B Fresh material was exposed to the air.C The samples got stuck inside the scoop.D The robotic arm hit a hard rock.3. Which one of the following statements is NOT meant by the writer?A Scientists have been trying to break the ice-rich layers of soil on Mars.B Scientists have been surprised by how the soil on Mars behaves.C Scientists have been trying to find out if there is life supporting material on Mars.D Scientists have been trying to know if water ice will melt.4. Where are the scientists involved in the research from?A They are from America.B They are from Canada.C They are from both America and Canada.D They are from neither America nor Canada.5. Which of the following do you think is the best description of Phoenix's Surface Stereo Imager camera, according to your understanding of the passage?A It imitates human vision and is able to capture three-dimensional images.B It imitates human voice and is able to record slight sounds while taking photos.C It takes clear photos that show every detail of the object.D It is this particular type of camera that can take wide angle pictures."Hidden" Species May Be Surprisingly Common Cryptic species — animals that appear identical but are genetically quite distant —may be much more widespread than previously thought. The findings could have major implications in areas ranging from biodiversity estimates and wildlife management, to our understanding of infectious diseases and evolution.Reports of cryptic species have increased dramatically over the past two decades with the advent of relatively inexpensive DNA sequencing technology. Markus Pfenninger and Klaus Schwenk, of the Goethe-Universitat in Frankfurt, Germany, analyzed all known data on cryptic animal species and discovered that they are found in equal proportions throughout all major branches of the animal kingdom and occur in equal numbers in all biogeographical regions.Scientists had previously speculated that cryptic species were predominantly found in insects and reptiles, and were more likely to occur in tropical rather than temperate regions. “Species that are seemingly widespread and abundant could in reality be many different Cryptic species that have low populations and are highly endangered," says Pfenninger. Until the genetic information of all species in at least one taxon is thoroughly studied, no one will know just how many cryptic species exist, "It could be as high as 30%, Pfenninger says."I'm extremely surprised by their results," says Alex Smith of the University of Guelph in Ontario, Canada. "It's a call to arms to keep doing the broad kind of genetic studies that we are doing. "Sampling as many individuals as possible, scientists hope to complete. work on all fish and birds in another 5 to 10 years. Once either of these taxonomic groups is completed, Pfenninger says researchers will be able to decide how many cryptic species exist throughout the animal kingdom.Examples of cryptic species include the African elephant. A 2001 study found the elephants were actually two genetically distinct, non-interbreeding species, the African bush elephant and the African elephant. The species are currentlylisted as vulnerable and threatened, respectively, by the World Conservation Union (WCU).The reclassifications are more than an academic exercise. They define populations that have evolved independently of each other and whose genetic differences can have significant consequences.In the early 1900s misidentification of mosquito species based on morphology confused: attempts to control malaria in Europe. Ultimately, what was thought to be a single species was actually made up of six sibling species, only three of which transmitted the disease. "The basic unit in biology is always the species, and you have to know what you are dealing with," Pfenninger says. Much previous research is now no longer used, he Says, because it is not clear what species was being studied.练习：1. Which of the following about the significance of the research on cryptic species is NOT true?A The results of the research can help the development of many other research areas.B The results of the research can help the development of biodiversity estimates.C The results of the research can help our understanding of infectious disease evolution.D The results of the research can help our understanding of "survival of the fittest. "2. What was scientists' understanding of cryptic species?A They occurred in equal numbers in all biogeographical regions.B They were mostly found in insects and reptiles.C They were likely to be in tropical rather than temperate regions.D Both Band C.3. Do scientists know how many cryptic species exist?A Not yet.B Yes, they do.C They will know the answer in another one or two-years.D They will never know the answer.4. Which of the following about the African bush elephant and the African elephant is true?A The WCU are interbreeding those elephants.B They are interbreeding species.C They are two genetically distant species.D They depend on each other for survival.5. People were confused in their attempts to control malaria in Europe inthe early 1900s. because scientistsA identified only one mosquito species instead of six species.B thought only three mosquito species transmitted disease.C thought there was only one mosquito species.D did not know what species was being studied.Thirsty in Karachi （卫生A）After two weeks in Karachi, I’m not sure whether to laugh or to cry. Either way, it involves water—or rather the lack of it.In Western Europe or the US, you only have to turn on the tap and you’ll see a jet of cold water, ready to drink, cook and bathe in, or wash the car. Turn on the tap in Karachi and you’ll be lucky to fill a few buckets. Until 1947 the city was part of British India, whose engineers built and maintained a modest water supply network for the city’s 500,000 inhabitants. Today, Karachi is home to around 12 million people. Half of them live in slum townships, with little or no water through the mains. Even the rich half usually have to wait days before anything tickles through their pipes. And the coloured liquid that finally emerges is usually too contaminated to drink.Half usually have to wait days before anything tickles through their pipes. And the coloured liquid that finally emerges is usually too contaminated to drink.According to the state-owned Karachi Water and Sewerage Board, the city needs more than 2,500 million litres of water each day. The board currently supplies 1,650 million litres of which nearly 40 per cent is lost from leaks—and theft. Leaks are dime a dozen to water utilities the world over, but theft?Karachi’s unlikely water pirates turn out to be ordinary families struggling to get adequate supplies of one of life’s necessities. Stea ling water takes many forms. The simplest is to buy a suction pump and get it attached to the water pipe that feeds your house from the mains. This should maximize your share of water every time the board switches on the supply. When the practice started 20 years ago, the pumps would be carefully hidden or disguised as garden ornaments. These days people hardly bother. The pumps are so widespread and water board inspectors so thin on the ground that when officials do confiscate a pump its owner simply buy a replacement.Insisting that people obey the law won’t work because most households have little alternative but to steal. For its part, the Karachi Water and Sewerage Board says it would dearly like to make life easier, but finds itself mired in debt beca use most residents either won’t pay water charges or can’t afford to the Urban Resource Centre, a Karachi-based think tank, of the 1.2 million known consumers of water only 750,000 are billed, of whom just 163,000 actually pay for their supplies. The board makes a perpetual loss, and there is no money to improve the system or even plug the leaks. Worse, the board increasingly relies on international loans from institutions such as the Asian Development Bank, which only makes its debt worse.The joke is that the owners of the suction pumps end up with little—if any—extra water. Your house is in a line with 20 other households all tapping into one horizontal pipeline. All you can end up doing, given you have pumps of equal strength, is redistri bute each other’s entitlement and pay higher electricity bills into the bargain.Back home in London, I’ll remember not to complain about the water meter, or the hosepipe ban.练习：1．According to the passage, people in Karachi today suffer from a short supply of water becauseA. the water supply network built in 1947 has stopped to function.B. the city has become much larger than before.C. old networks can not meet the need of the city’s greatly-increased population.D. other city is longer a part of British India.2. Now people in Karachi do not hide or disguise the suction pumps they use to steal water becauseA. the pumps are no longer wanted as garden ornaments.B. water supply board officials no longer confiscate them.C. it does not cost much money to buy a new one.D. many households have them and there are very few inspectors around to try to find them.3. Confronted with a severe shortage of water supply, the city’s Water and Sewerage BoardA. tries to improve the water supply system with borrowed money.B. is not making any effort to improve the situation.C. urges the consumers to obey the law.D. charges the consumers more for the water they use.4.Which of the following is true of the owners of the suction pumps, if their neighbors have equally powerful pumps as they do?A. They get some extra water.B. They only pay more for electricity.C. They share what they can get with their neighbors.D. They replace their pumps with new ones.5. Which of the following is true about the author when he is back home in London?A. He misses the days he spent in Karachi.B. He forgets the complaints he made in Karachi.C. He is content with the water supply in London.D. he complains about the water supply in London.（注：可编辑下载，若有不当之处，请指正，谢谢!）。

Common Questions about DreamsDoes everyone dream?Yes. Research shows that we all dream. We have our most vivid dreams during a type of sleep called Rapid Eye Movement (REM) sleep. During REM sleep, the brain is very active. The eyes move quickly back and forth under the lids, and the large muscles of the body are relaxed. REM sleep occurs every 90-100 minutes, three to four times a night, and it lasts longer as the night goes on. ___1___ We dream at other times during the night, too, but those dreams are less vivid.Do people remember their dreams?A few people remember their dreams. However, most people forget nearly everything that happened during the night —dreams, thoughts, and the short periods of time when they were awake. ___2___ It seems that the memory of the dream is not totally lost, but for some reason it is very hard to bring it back. If you want to remember your dream，the best thing to do is to write it down as soon as you wake up.Are dreams in color?Most dreams are in color. However, people may not be aware of it for two reasons ：They don’t usually remember the details of their dreams, or they don’t notice the color because it is such a natural part of our lives. ___3___Do dreams have meaning?Scientists continue to debate this issue. ___4___ Some people use dreams to help them learn more about their feelings, thoughts, behavior, motives, and values. Others find that dreams can help them solve problems. It’s also true that artists, writers, and scientists often get creative ideas from dreams.How can I learn to understand my dreams?The most important thing to remember is that your dreams are personal. The people, actions, and situations in your dreams reflect your experience, your thoughts, and your feelings. Some dream experts believe that there are certain types of dreams that many people have，even if they come from different cultures or time periods. Usually, however, the same dream will have different meanings for different people. For example, an elephant in a dream may mean one thing to a zookeeper and something very different to a child whose favorite toy is a stuffed elephant. ___5___ Then look for links between your dreams and what is happening in your daily life. If you think hard and you are patient, perhaps the meaning of your dreams will become clearer to you.练习：A However, people who spend time thinking about their dreams believe that they are meaningful and useful.B The final REM period may last as long as 45 minutes.C People who are very aware of color when they are awake probably notice color more often in their dreams.D Our most powerful dreams don’t happen during deep sleep.E To learn to understand your dreams, think about what each part of the dreammeans to you or reminds you of.F Sometimes, though, people suddenly remember a dream later in the day or on another day.Baby TalkBabies normally start to talk when they are 13 to 15 months old. Ryan Jones is only eight months old, but he is already “talking” with his parents. When lie is hungry, he opens and closes his hand. This means milk. He also knows the signs for his favorite toy and the word more.Ryan is not deaf, and his parents are not deaf, but his mother and father are teaching him to sign. They say a word and make a sign at the same time. They repeat this again and again. When ___1___ Ryan’s parents think that he will be a happier baby because he can communicate with them.Ryan s parents are teaching Ryan to sign because of a man named Joseph Garcia. Although Garcia was not from a deaf family, he decided to learn American Sign Language (ASL). First, he took courses in ASL. Then he got a job helping deaf people communicate with hearing people. In his work, he saw many deaf parents sign to their infants. He noticed that these babies were able to communicate much earlier than hearing children. ___2___ When they were one year old, they could use as many as 50 signs.Garcia decided to try something new. He taught ASL to parents who were not deaf. The families started to teach signs to their infants when they were six or seven months old. ___3___ More and more parents took Garcia’s ASL classes. Like Ryan’s family, they were excited about signing with their babies. They wanted to give their babies a way to communicate before they could use spoken words.Some peopl e worry about signing to babies. They are afraid that these babies won’t feel a need to talk. Maybe they will develop spoken language later than other babies. ___4___ In fact, one study found just the opposite. Signing babies actually learned to speak earlier than other children. As they grow older, these children are more interested in books. They also score higher on intelligence tests1.There is still a big question for parents: Which are the best signs to teach their babies? Some parents make their own signs. Other parents want to teach ASL. ___5___ There’s no clear answer, but we do know this: All signing babies and their families are talking quite a lot!练习：A However, research does not show this.B All parents want to teach babies to sign.C Ryan learns a new sign, his family is very excited.D These babies started using signs about two months later.E It can be useful because many people understand it.F They talked with signs by the time they were eight months old.The Apgar TestThe baby was born at 3:36 p. m. At 3:37, she scored 4 out of 10 on her first test. At 3:41, she scored 8 out of 10. The doctor was glad.Another baby, born at 8:24 p. m., scored 3 out of 10 on his first test. He scored 4 out of 10 on his second test. He took another test at 8:34 and scored 5. ___1___ He called for help1.These newborn babies took a test called the Apgar test. This test helps doctors diagnose problems. ___2___ Most babies take two tests. The first is at 1 minute after birth, and the second is at 5 minutes after birth. If a baby’s score at 5 minutes is less than 6, the baby takes another test at 10 minutes after birth.The Apgar test is not an intelligence test. It’s a test that shows a baby’s health right after it is born. The Apgar test measur es things such as a baby’s color, heart rate, and breathing. The test has five parts, and the score for each part can be 0, 1, or 2. ___3___A doctor named Virginia Apgar developed the test. Apgar went to medical school at Columbia University in New York City in 1929. She faced many challenges because she was the first woman in the program. However, she was one of the best students in her class. After medical school, she started treating patients2.Apgar also became a researcher in anesthesiology, a new topic in medicine at the time3. During her studies, she learned how to give patients anesthesia. ___4___In the 1940s, many women started to have anesthesia when they gave birth. Apgar had a question: How does anesthesia affect newborn babies? In 1949, when Apgar was a professor at Columbia’s medical school, she created her simple test. She wrote a paper about her methods in 1953. Soon after, people started using the Apgar test around the world.In her work, Apgar saw that many newborns had problems. She wanted to help these babies survive. She stopped practicing medicine in 1959, and she went back to school to get a master’s degree in public health. ___5___Today, the Apgar test is still used all over the world. Newborn babies don’t know it, but Virginia Apgar is a very important person in the first few minutes of their lives.练习：A Doctors add the scores together for the total Apgar score.B She spent the rest of her life doing research and raising money to help newborn babies.C A score of 10 is uncommon.D The doctor was worried.E They decide if a baby is normal or needs special care.F Anesthesia is a procedure that makes patients lose consciousness, so they do not feel any pain during surgeryIce Cream Taster Has Sweet JobJohn Harrison h as what must be the most wanted job in the United States. He’s the official taster for Edy’s Grand Ice Cream, one of the nation’s best-selling brands. Harrison’s taste buds are insured for $1 million. ___1___ And when he isn’t doing that, he travels, buyin g Edy’s in supermarkets all over the country so that he can check for perfect appearance, texture, and flavor.After I interviewed Harrison, I realized that the life of an ice cream taster isn’t all Cookies ’n Cream — a flavor that* he invented, by the way. No, it’s extremely hard work, which requires discipline and selflessness.For one thing, he doesn’t swallow on the job. Like a coffee taster, Harrison spits. Using a gold spoon to avoid “off” flavors, he takes a small bite and moves it around in his mouth to introduce it to all 9,000 or so taste buds. ___2___ Then he breathes in gently to bring the aroma up through the back of his nose. Each step helps Harrison evaluate whether the ice cream has a good balance of dairy, sweetness, and added ingredients 一the three-flavor components of ice cream. Then, even if the ice cream tastes heavenly, he puts it into a trash can. A full stomach makes it, impossible to judge the quality of the flavors.During the workweek, Harrison told me that he has to make other sacrifices, too: no onions, garlic, or spicy food, and no caffeine. Caffeine will block the taste buds, he says, so his breakfast is a cup of herbal tea. ___3___Harrison’s family has been in the ice cream business in one way or another1 for four generations, so Harrison has spent his entire life with it2. However, he has never lost his love for its cold, creamy sweetness. ___4___ On these occasions3, he does swallow, and he eats about a quart (0.95 liters) each week. By comparison4, the average person in the United States eats 23.2 quarts (21. 96 liters) of ice cream and other frozen dairy products each year.Edy’s ice cream is available in dozens of flavors. So what flavor does the best-trained ice-cream taster in the country prefer? Vanilla! In fact, vanilla is the best-selling variety in the United States. ___5___ “It’s a very complex flavor,” Harrison says.练习：A However, you should never call it plain vanilla.B He even orders ice cream in restaurants for dessert.C Next he smack-smack-smacks his lips to get some air into the sample.D This is a small price to pay for what he calls the world’s best job.E In his younger days, he would help out at the ice cream factory his uncle owned.F He gets to sample 60 ice creams a day at Edy’s headqu arters in Oakland, California.Primer on SmellIn addition to bringing out1 the flavor of food, what does the sense of smell do for us? Smell “gives us information about place, about where we are,” says Randall Reed, a Johns Hopkins University professor whose specialty is the sense of smell. ___1___“Whether we realize it or not, we collect a lot of information about who is around us based on smell,” says Reed.Even at a distance, odors can warn us of2 trouble — spoiled food, leaking gas, or fire. “It’s a great alert,” offers Donald Leopold, a doctor at Johns Hopkins. For example, if something in the oven is burning, everyone in the house knows it.With just a simple scent, smell can also evoke very intense emotion. Let’s say, for example, that the smell is purple petunias. ___2___ Now let’s imagine that your mother died when you were three, and she used to have a flower garden. You wouldn’t need to identify the smell or to have conscious memories of your mother or her garden. You would feel sad as soon as you smelled that spicy odor.Compared with3 animals, how well do people detect smelts?That depends on what you mean by “how well”. We are low on receptor cells ：current estimates say that humans have roughly five million smell-receptor cells, about as many as a mouse. ___3___Reed says that, across species, there is a relatively good correlation between the number of receptor cells and how strong the sense of smell is. “You can hardly find the olfactory bulb in a human brain ——it’s a pea-sized object. In a mouse, it’s a little bigger. It’s bean-sized in a rat, about the size of your little finger in a rabbit, and the size of your thumb in a bloodhound.”Does that mean that our sense of smell is not very acute?Not exactly. While we may not have the olfactory range of other creatures, the receptors we do have are as sensitive as those of any animal. ___4___ A trained “nose”, such as that of a professional in the perfume business, can name and distinguish about 10,000 odors. Reed says that a perfume expert can sniff a modem scent that has a hundred different odorants in it, go into the lab, and list the ingredients. “In a modest amount of time, he comes back with what to you or me would smell like a perfect imitation of that perfume. It’s amazing.”What happens to4 our sense of smell as we age?Many people continue to have good olfactory function as they get older. ___5___ Leopold says that smell is generally highest in childhood, stays the same from the teens through the 50s, and drops starting at about 60 for women and 65 for men. “The average 80-year-old is only able to smell things half as well as the average 20-year-old,” says Leopold.练习：A These flowers have a rich spiciness that no other petunia has.B Odors, or smells, can warn us about trouble.C That’s not the rule, however.D And smell tells us about people.E We can also think, and we make conscious (and successful) efforts to tell the difference between one smell and another.F A rat has some 10 million, a rabbit 20 million, and a bloodhound 100 million.。

梦是什么几百年来，人们都对他们梦到的奇异的事情感到疑惑。

一些心理学家认为，这种大脑的夜间活动并没有特殊含义，另一些人则认为，梦是生命重要的一部分。

实际上，许多专家认为，梦能揭示人的心理和情感活动。

近代以前，很多人认为梦传递的是上帝的信息。

直到20世纪，人们才开始从科学的角度研究梦。

奥地利心理学家西格蒙德·弗洛伊德或许是第一个用科学的方法研究梦的人。

在他的著作《梦的解析》(1900) 中，弗洛伊德写道，梦是一个人愿望的表达。

他认为梦打开了一扇窗，让人们得以表达在生活中不敢表达的情感、思想和恐惧。

瑞士精神病学家卡尔·荣格曾是弗洛伊德的学生，但他对梦的看法与弗洛伊德不同，他认为，梦的作用是给做梦的人传递一种信息，而人们通过自己的梦，可以对自己有一个更深刻的了解。

比如，如果一个人梦到从高处坠落，那么他应该反思自己是不是自视过高。

反过来，如果梦中自己成了英雄，应该想想平时可能太看低自己了。

现代心理学家还在继续发展关于梦的理论，来自位于圣克鲁兹的加利福尼亚大学的威廉·多姆霍夫就是其中一位。

他认为，梦境和一个人的日常生活、思想和行为都紧密相关，比方说，一个罪犯就可能梦到犯罪。

多姆霍夫还认为，梦和年龄也有关系。

他的研究表明，孩子不像成人那么多梦。

他认为，做梦也是一项心理机能，也随着年龄增长而发展。

多姆霍夫还发现梦和性别之间的关系。

通过研究.他发现男性和女性的梦境常常是不同的。

例如，在男性梦境中出现的通常是其他男性，而且常与打斗有关，而女性的梦境则不是这样。

多姆霍夫研究了全世界来自11种不同文化的古今案例，得出了上述结论。

梦能帮助我们更好地了解自己吗？心理学家还在尝试通过不同方式来解答这个问题，不过，有一件事他们是意见一致的：如果你梦到有不好的事要发生，不要慌张。

梦确实有含义，但也不意味着你梦到的事真的会发生。

要记住，梦中的世界并不是真实的世界。

音乐生物学人们把音乐作为一种高效的交流方式，在爱情中它也可能会起到重要的作用。

2014年职称英语考试教材理工类新增文章阅读判断:(A)第十一篇：Bill Gates: Unleashing Your CreativityI've always been an optimist and I suppose it is rooted in my belief that the power of creativity and intelligence can make the word a better place.For as long as I can remember, I've loved learning new things and solving problems. So when I sat down at a computer for the first time in seventh grade, I was hooked. It was a clunky old teletype machine and it could barely do anything compared to the computers we have today. But it changed my life.When my friend Paul Allen and I started Microsoft 30 years ago, we had a vision of "acomputer on every desk and in every home", which probably sounded a little too optimistic at a time when most computers were the size of refrigerators. But we believed that personal computers would change the world. And they have.And after 30 years, I'm still as inspired by computers as I was back in seventh grade.I believe that computers are the most incredible tool we can use to feed our curiosity andinventiveness -- to help us solve problems that even the smartest people couldn't solve on their own.Computers have transformed how we learn, giving kids everywhere a window into all of the world's knowledge. They're helping us build communities around the things we care about and to stay close to the people who are important to us, no matter where they are. Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it "tap-dancing to Work". My job at Microsoft is as challenging as ever, but what makes me "tap-danceing to work" is when we show people something new, like a computer that can recognize your handwriting or your speech, or one that can store a lifetime's worth of photos, and they say, "I didn't know you could do that with a PC5 !"But for all the cool things that a person can do with a PC, there are lots of other ways we can put our creativity and intelligence to work to improve our world6. There are still far too many people in the world whose most basic needs go unmet7. Every year, for example, millions ofpeople die from diseases that are easy to prevent or treat in the developed world.I believe that my own good fortune brings with it a responsibility to give back to the world.My wife, Melinda, and I have committed to improving health and education in a way that can help as many people as possible.As a father, I believe that the death of a child in Africa is no less poignant or tragic than9 the death of a child anywhere else, and that it doesn't take much to make an immense difference in these children's lives.I'm still very much an optimist, and I believe that progress on even the world's toughestproblems is possible -- and it's happening every day. We're seeing new drugs for deadly diseases,new diagnostic tools, and new attention paid to the health problems in the developing world.I'm excited by the possibilities I see for medicine, for education and, of course, fortechnology. And I believe that through our natural inventiveness,creativity and willingness to solve tough problems, we're going to make some amazing achievements in all these areas in my lifetime.注释：rooted in：扎根于;深深地存在于was a clunky old teletype machine and it could barely do anything compared to the computers we have today.那是一台笨重的旧式电传打字机，跟我们今天的电脑相比几乎干不了什么事。

2014年职称英语(理工类)教材新增文章第二部分阅读判断﹡第8篇What Is a Dream?（B级）For centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning. Others, however, think that dreams are an important part of our lives. In fact., many experts believe that dreams can tell us about a person's mind and emotions.Before modern times,many people thought that dreams contained messages from God. It Was only in the twentieth century that people started to study dreams in a scientific way.The Austrian psychologist, Sigmund Freud, was probably the first person to Study dreams scientifically. In his famous book, The interpretation of Dreams ( 1900) , Freud wrote that dreams are an expression of a person's wishes. He believed that dreams allow people to express the feelings , thoughts, and fears that they are afraid to express in real life.The Swiss psychiatrist Carl Jung was once a student of Freud's. Jung,however,had a diffent idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer.He thought people could learn more about themselves by thinking about their dreams.For example,people who dream about falling may learn that they have too high an opinion of themselves. On the other hand,people who dream about being heroes may learn that they think too little of themselves.Modem-day psychologists continue to develop theories about dreams. For example,psychologist William Domhoff from the University of Califoria, Santa Cruz, believes that dreams are tightly linked to a person's daily life, thoughts, and behavior. A criminal, for example, might dream about crime.Domhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults. According to Domhoff, dreaming is a mental skill that needs time to develop.He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. For example, the people in men's dreams are often other men, and the dreams often involve fighting. This is not true of women's dreams. Domhoff found this gender difference in the dreams of people from ll cultures around the world,including both modern and traditional ones.Can dreams help us understand ourselves? Psychologists continue to try to answer th is question in different ways. However,one thing they agree on is this :If you dream that somethingterrible is going to occur,you shouldn't panic. The dream may have meaning,but it does not mean that some terrible event will actually take place. It's important to remember that the world of dreams is not the real world.词汇：psychologist [saɪˈkɔlədʒɪst] n．心理学家psychiatrist [saɪˈkaɪətrɪst]，2．精神病学家（医生）Austrian[ˈɔstrɪən] adj奥地利的 gender[ˈdʒendə] n．性别注释：Sigmund Freud：西格蒙德·弗洛伊德（1856一1939），犹太人，奥地利精神病医生及精神分析学家。
