阅读理解篇 1Making Light of1 SleepAll we have a clock located inside our brains. Similar to your bedside alarm clock，your internal clock2 runs on a 24-hour cycle. This cycle，called a circadian rhythm，helps control when you wake，when you eat and when you sleep.Somewhere around puberty，something happens in the timing of the biological clock. The clock pushes forward，so adolescents and teenagers are unable to fall asleep as early as they used to. When your mother tells you it's time for bed，your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later.This shift4 is natural for teenagers. But staying up very late and sleeping late can get your body's clock out of sync with the cycle of light and dark5. It can also make it hard to get out of bed in the morning and may bring other problems，too. Teenagers are put in a kind of a gray cloud6 when they don't get enough sleep，says Mary Carskadon，a sleep researcher at Brown University in Providence，RI7 .It affects their mood and their ability to think and learn.But just like your alarm clock，your internal clock can be reset. In fact，it automatically resets itself every day. How? By using the light it gets through your eyes.Scientists have known for a long time that the light of day and the dark of night play important roles in setting our internal clocks. For years，researchers thought that the signals that synchronize the body's clock8 were handled through the same pathways that we use to see.But recent discoveries show that the human eye has two separate light-sensing systems. One system allows us to see. The second system tells our body whether it's day or night.词汇：circadian adj. 昼夜节奏的，生理节奏的adolescent n．青少年；adj．青少年的puberty n．发育；青春期sync n. （口语）同步；和谐，协调synchronize V.（使）同时发生；（使）同步注释：1.make light of ：轻视，不在乎。

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

+第四＋五篇Small But WiseOn December 14,NASA1 blasted a small but mighty telescope into space. The telescope is called WISE and is about as wide around as a trashcan. Don't let its small size fool you:WISE has a powerful digital camera, and it will be taking pictures of some the wildest 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 spectrum they glow.练习：1 .What is so special about WISE?A It is small in size but carries a large camera.B It is as small as a trashcan.C Its digital camera can help astronomers to see the unknown space.D Never before has a telescope carried a digital camera in space.2. Which is NOT the synonym for the word "snap" in the third paragraph?A make.B shoot.C takeD photograph.3. The camera on WISEA is no different from an ordinary camera.B does not see infrared radiation while the ordinary camera does.C catches the infrared radiation while the ordinary camera does not.D reflects light that human eyes can see.4. Which of the following is NOT correct about"asteroids" according to paragraph 7?A Asteroids float through space giving off visible light.B Asteroids do not reflect light that reaches them.C It is difficult to take asteroids' pictures by ordinary cameras,D The WISE telescope can take pictures of asteroids5.What is implied in the last paragraph?A Brown dwarfs give off visible light.B Brown dwarfs give off infrared radiation.C Brown dwarfs are power stars like the sun.D Brown dwarfs are impossible to see with the WISE telescope.答案与题解：1.

Their study is inACS’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 thananticipated. 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 informenergy-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。

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

The road crew were playing a game with dollar notes. Folding them into small planes to see whose would fly the furthest.1 Having nothing better to do，I joined in and won five，and then took the opportunity to escape with my profit. Despite the evil-looking clouds，I had to get out for a while.I headed for a shop on the other side of the street. Unlike the others，it didn't have a sign shouting its name and business，and instead of the usual impersonal modern lighting，there was an appealing glow inside. Strangely nothing was displayed in the window. Not put off by this，I went inside.It took my breath away. I didn't know where to look, where to start. On one wall there hung three hand-stitched American quilts that were in such wonderful condition they might have been newly-made. I came across tin toys and antique furniture, and on the wall in front of me, a 1957 Stratocaster guitar , also in excellent condition. A card pushed between the strings said $50. I ran my hand along a long shelf of records, reading their titles. And there was more...―Can I help you？‖ She startled me. I hadn't even seen the woman behind the counter come in. The way she looked at me, so directly and with such power. It was a look of such intensity that for a moment I felt as if I were wrapped in some kind of magnetic or electrical field. I found it hard to take and almost turned away. But though it was uncomfortable. I was fascinated by the experience of her looking straight into me, and by the feeling that I was neither a stranger, nor strange, to her.Besides amusement her expression showed sympathy. It was impossible to tell her age；shereminded me faintly of my grandmother because, although her eyes were friendly, I could see that she was not a woman to fall out with. I spoke at last. 'I was just looking really,' I said, though secretly wondering how much of the stuff I could cram into the bus.The woman turned away and went at once towards a back room, indicating that I should follow her. But it in no way lived up to the first room. The light made me feel peculiar, too. It came from an oil lamp that was hung from the centre of the ceiling and created huge shadows over everything. There were no rare electric guitars, no old necklaces, no hand-painted boxes with delicate flowers. It was also obvious that it must have taken years, decades, to collect so much rubbish, so many old documents arid papers.I noticed some old books, whose gold lettering had faded, making their titles impossible to read. 'They look interesting,' I said, with some hesitation. 'To be able to understand that kind of writing you must first have had a similar experience,' she said clearly. She noted the confused look on my face, but didn't add anything.She reached up for a small book which she handed to me. 'This is the best book I can give you at th e moment,' she laughed. ―If you use it.‖ I opened the book to find it full. or rather empty, with blank white pages, but paid her the few dollars she asked for it, becoming embarrassed when I realised the notes were still folded into little paper planes.

Similar to your bedside alarm clock, your internal clock2 runs on a 24-hour cycle. This cycle, called a circadian rhythm, helps control when you wake, when you eat and when you sleep.Somewhere around puberty, something happens in the timing of the biological clock. The clock pushes forward, so adolescents and teenagers are unable to fall asleep as early as they used to. When your mother tells you it's time for bed, your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later.This shift4 is natural for teenagers. But staying up very late and sleeping late can get your body's clock out of sync with the cycle of light and dark5. It can also make it hard to get out of bed in the morning and may bring other problems, too. Teenagers are put in a kind of a gray cloud6when they don't get enough sleep, says Mary Carskadon, a sleep researcher at Brown University in Providence, RI7. It affects their mood and their ability to think and learn.But just like your alarm clock, your internal clock can be reset. In fact, it automatically resets itself every day. How? By using the light it gets through your eyes.Scientists have known for a long time that the light of day and the dark of night play important roles in setting our internal clocks. For years, researchers thought that the signals that synchronize the body's clock8 were handled through the same pathways that we use to see.But recent discoveries show that the human eye has two separate light-sensing systems. One system allows us to see. The second system tells our body whether it's day or night.练习：1.

2012职称英语教材新增阅读文章包括答案(仅供参考)综合Telling Tales about PeopleOne of the most common types of nonfiction, and one that many people enjoy reading, is stories about people's lives. These stories fall into three general categories: autobiography, memoir, and biography.An autobiography is the story of a person's life written by himself or herself. Often it begins with the person's earliest recollections and ends in the present. Autobiography writers may not be entirely objective in the way they present themselves. However, they offer the reader a good look at the way they are and what makes them that way. People as diverse as Benjarmin Franklin and Helen Keller have written autobiographies. 1Other writers, such as James Joyce，have written thinly fictionalized accounts of their lives. These are not autobiographies，but they are very close to it.Memoirs, strictly speaking, are autobiographical accounts that focus as much on the events of the times as on the life of the注释：1. People as diverse as Benjamin Franklin and Helen Keller have written autobiographies. 就像本杰明?富兰克林和海伦?凯勒一样，各种各样的人们已经写了自传。

3. stay up：不睡觉，熬夜4. This shift：这种调整。

RI是Rhode Island（罗得岛）的首字母缩写；Providence 是罗得岛州的首府。
布朗大学是美国一流大学，创建于1764 年，是世界闻名的美国“常春藤联盟”（还包括哈佛大学、耶鲁大学、普林斯顿大学、布朗大学、哥伦比亚大学、宾夕法尼亚大学、达特茅斯大学和康奈尔大学）中的一员。
8. the signals that synchronize the body's clock：平衡生物钟的光信号不要太在意睡眠我们每个人的大脑里都有一个像我们床边的闹钟一样的生物钟。
人脑里的生物钟24小时走一圈，这一圈也就是一次完整的昼夜节律，正是这个节律决定了我们吃饭、睡觉和起床的时间。
青春期时，人的生物钟在定时方面会发生变化，生物钟会提前。
这时，青少年会比以前睡得晚，所以当你妈妈告诉你该睡觉时，你的生物钟可能会让你多推迟几小时，并且电脑或电视光线可能会导致你熬夜到更晚。
生物钟的这种变化对青少年说是正常的，但熬夜到太晚会打乱你生物钟与昼夜时间循环之间的平衡，这样就会带来一些问题，例如：早晨很难按时起床。
位于美国罗得州布郎大学睡眠方面的研究员Mary Carskadon说：“当青少年睡眠不足时会打不起精神，这将影响到他们心情、学习和思考问题的状态。
”其实生物钟与闹钟一样，也是可调的，事实上，生物钟每天都在进行着自我调节，其方式就是通过你眼睛接收到光线的变化。
很早之前，科学家就知道了昼夜光线强弱的变化对生物钟调节起到了重要的作用，长久以来，研究者们认为眼睛所接受到的平衡生物钟的光信号同样作用于人类的视觉系统。
但最近几年的研究发现，人类眼睛有两个感光系统，一个是视觉系统，而另一个是感知昼夜的系统。
