"Liquefaction" Key to Much of Japanese Earthquake DamageThe massive subduction zone1 earthquake in Japan caused a significant level of soil "liquefaction"2 that has surprised researchers with its 1 severity, a new analysis shows."We've seen localized3 examples of soil liquefaction as extreme as this before, but the distance and 2 of damage in Japan were unusually severe," said Scott Ashford, a professor of geotechnical engineering4 at Oregon State University5. "Entire structures were tilted and sinking into the sediments," Ashford said. "The shifts in soil destroyed water, drain and gas pipelines6, crippling the utilities and infrastructure these communities need to 3 . We saw some places that sank as much as four feet."Some degree of soil liquefaction7 is common in almost any major earthquake. It's a phenomenon in which soils soaked with water, particularly recent sediments or sand, can lose much of their 4 and flow during an earthquake. This can allow structures to shift or sink or 5 .But most earthquakes are much 6 than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this8."With such a long-lasting earthquake, we saw 7 structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes," he said. "And it was clear that younger sediments, and especially areas built on 8 filled ground, are much more vulnerable."The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil 9 and better prepare for it in the future. Ashford said it was critical for the team to collect the information quickly, 10 damage was removed in the recovery efforts9."There's no doubt that we'll learn things from what happened in Japan10 that11 will help us to reduce risks in other similar 11 ," Ashford said. "Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns."Ashford pointed out that northern California have younger soils vulnerable to liquefaction ---on the coast, near river deposits or in areas with filled ground. The "young" sediments, in geologic terms, may be those 12 within the past 10,000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.Anything 13 a river and old flood plains is a suspect12, and the Oregon Department of Transportation has already concluded that 1,100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have been reinforced to 14 collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction 15 helped prevent many buildings from collapse ---even as they tilted and sank into the ground.Germs on banknotesPeople in different countries use different types of 1 yuan in China, pesos in Mexico, pounds in the United Kingdom, dollars in the United States, Australia and New Zealand. They may use 2 currencies, but these countries, and probably all countries, still have one thing in common1: Germs on the banknotes.Scientists have been studying the germs on money for well over2 100 years. At the turn of the 20th 3 , some researchers began to suspect that germs living on money could spread disease.Most studies of germy money have looked at the germs on the currency 4 one country. In a new study, Frank Vriesekoop3 and other researchers compared the germ populations found on bills of different 5 .Vriesekoop3 is a microbiologist at the University of Ballarat in Australia4. He led the study, which compared the germ populations found on money 6 from 10 nations. The scientists studied 1,280 banknotes in total; all came from places where people buy food, like supermarkets street vendors and cafes, 7 those businesses often rely on cash.Overall, the Australian dollars hosted the fewest live bacteria ---- no more than 10 per square centimeter. Chinese yuan had the most ---- about 100 per square centimeter. Most of the germs on money probably would notcause harm.What we call "paper" money usually isn't made from paper. The U. S. dollar, for example, is printed on fabric that is mostly 8 .Different countries may use different 9 to print their money. Some of the currencies studied by Vriesekoop and his 10 such as the American dollar were made from cotton. Others were made from polymers.The three 11 with the lowest numbers of bacteria were all printed on polymers. They included the Australian dollar, the New Zealand dollar and some Mexican pesos.The other currencies were printed on fabric made 12 of cotton. Fewer germs lived on the polymer notes. This connection suggests that 13 have a harder time staying alive on polymer surfaces. Scientists need to do more studies to understand how germs live on money-----and whether or not we need to be concerned. Vnesekoop is now starting a study that will 14 the amounts of time bacteria can stay alive on different types of bills.Whatever Vriesekoop finds, the fact remains: Paper money harbors germs We should wash our 15 after touching it; after all5, you never know where your money 's been. Or what's living on it.Solar Power without Solar CellsA dramatic and surprising magnetic effect of light discovered by University of Michigan1 researchers could lead to solar power without traditional semiconductor-based solar cells.The researchers found a way to make an "optical 1 ," said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics.Light has electric and magnetic components. Until now, scientists thought the 2 of the magnetic field were so weak that they could be ignored. What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than 3 expected. 4 these circumstances, the magnetic effects develop strength equivalent to a strong electric effect."This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation," Rand said. "In solar cells, the 5 goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load2. Instead of the light being absorbed, energy is stored in the magnetic moment3. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power 6."What makes this possible is a previously undetected brand of "optical rectification4," says William Fisher, a doctoral student5 in applied physics. In traditional optical rectification, light's electric field causes a charge separation, or a pulling 7 of the positive and negative charges6 in a material. This sets up a voltage, similar to 8 in a battery.Rand and Fisher found that under the right circumstances and in right types of materials, the light's magnetic field can also create optical rectification. The light must be shone through7 a 9 that does not 10 electricity, such as glass. And it must be focused to an intensity of 10 million watts per square centimeter8. Sunlight isn't this intense on its own, but new materials are being sought that would work at lower intensities, Fisher said."In our most recent paper, we show that incoherent light9 like sunlight is theoretically almost as. 11 in producing charge separation as laser light is," Fisher said.This new 12 could make solar power cheaper, the researchers say. They predict that with improved materials they could achieve 10 percent efficiency in 13 solar power to useable energy. That's equivalent to today's commercial-grade solar cells."To manufacture 14 solar cells, you have to do extensive semiconductor processing," Fisher said. "All we would need are lenses to focus the light and a fiber to guide it. Glass works for 15 . It's already made in bulk10, and it doesn't require as much processing. Transparent ceramics might be even better."Chicken Soup for the Soul：Comfort Food Fights LonelinessMashed potatoes, macaroni and cheese, may be bad for your arteries．1 according to a study in Psychological Science, they're good for your heart and 2 ．The study focuses on "comfort food" and how it makes people feel．"For me 3 ,food has always played a big role in my family," says Jordan Troisi, a graduate student at the University of Buffalo, and lead author on the study．The study came out of the research program of his co-author Shira Gabriel．It has 4 non-human things that may affect human emotions．Some people reduce loneliness by bonding with their 5 TV show, building virtual relationships with a pop song singer or looking at pictures of loved ones．Troisi and Gabriel wondered if comfort food could have the same effect 6 making peoplethink of their nearest and dearest. In one experiment, in order to make 7 feel lonely, the researchers had them write for six minutes about a fight with someone close to them．Others were given an emotionally neutral writing assignment. Then, some people in each 8 wrote about the experience of eating a comfort food and others wrote about eating a new food．9 ,the researchers had participants 10 questions about their levels of loneliness．Writing about a fight with a close person made people feel lonely．But people who were generally 11 in their relationships would feel less lonely by writing about a comfort food．"We have found that comfort foods are consistently associated with those close to us．"says Troisi．"Thinking about or consuming these foods later then serves as a reminder of those close others．"In 12 essays on comfort food, many people wrote about the 13 of eating food with family and friends. In another experiment, 14 chicken soup in the lab made people think more about relationships, but only if they considered chicken soup to be a comfort food．This was a question they had been asked long before the experiment, along with many other questions, so they wouldn't remember it. Throughout everyone's daily lives they experience stress, often associated with our 15 with others," Troisi says．"Comfort food Can be an easy remedy for loneliness．Climate Change Poses Major Risks for Unprepared CitiesA new examination of urban policies has been 1 recently by Patricia Romero Lankao．She is a sociologist specializing in climate change and 2 development．She warns that many of the world's fast-growing urban areas，especially in developing countries．will likely suffer from the impacts of changing climate．Her work also concludes that most cities are failing to 3 emissions of carbon dioxide and other greenhouse 4 ．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 5 their residents."Cities are 6 sources of greenhouse gases．And urban populations are likely to be among those most severely affected by future climate change. Lankao's findings highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term 7 ．The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential 8 associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat 9 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 10 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 11 access to reliable drinking water，roads and basic services.Local governments, 12 ,should take measures to protect their residents."Unfortunately，they tend to move towards rhetoric 13 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 14 use. In fact, many local governments are taking a hands-off approach." Thus, she urges them to change their 15 policies and to take strong steps to prevent the harmful effects of climate change on cities.Free Statins With Fast Food Could Neutralize Heart RiskFast food outlets could provide statin drugs free of 1 so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London 2 in a new study．Statins reduce the 3 of unhealthy "LDL" cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person's heart attack 4 .In a paper published in the American Journal of Cardiology，Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is 5 to offset the increase in heart attack risk from 6 a cheeseburger and drinking a milkshake．Dr Francis，from the National Heart and Lung Institute at Imperial College London，who is the senior author of the study, said:"Statins don't cut out a11 of the 7 effects of cheeseburgers and French fries．It's better to avoid fatty food altogether．But we've worked out that in terms of your 8 of having a heart attack. Taking a statin can reduce your risk to more or less the same 9 as a fast food meal increases it." "It's ironic that people are free to take as many unhealthv condiments in fast food outlets as they 10 , 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 l 1 free of charge．It would cost less than 5 pence per 1 2 一not much different to a sachet of sugar." Dr Francis said．When people engage in risky behaviours like driving or smoking, they're encouraged to take 13 that lower their risk, 1ike 14 a seatbelt or choosing cigarettes with filters. Taking a statin is a rational way of 1 5 some of the risks of eating a fatty meal．。

+第十四篇Sharks Perform a Service for Earth's Waters鲨鱼有益于地球水系It is hard to get people to think of sharks as anything but a deadly enemy. They are thought to attack people frequently. But these fish perform a valuable service for earth's waters and for human beings. Yet business and sport fishing are threatening their existence .Some sharks are at risk of disappearing from Earth.要让人们相信鲨鱼不是人类的死敌不是一件很容易的事。

人们认为鲨鱼经常袭击人类。

但鲨鱼在为地球水系和人类做着有价值的贡献。

商业和捕鱼运动仍在威胁着它们的生存，有些鲨鱼面临着从地球上消失的危险。

Warm weather may influence both fish and shark activity. Many fish swim near coastal areas because of their warm waters. Experts say sharks may follow the fish into the same areas, where people also swim. In fact, most sharks do not purposely charge at or bite humans. They are thought to mistake a person for a sea animal, such as a seal or sea lion. That is why people should not swim in the ocean when the sun goes down or comes up. Those are the times when sharks are looking for food. Experts also say that bright colors and shiny jewelry may cause sharks to attack.温暖的气候影响着鱼类和鲨鱼的活动。

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 resetsitself every day. How? By using the light it gets through your eyes.Scientists have known for a long time that the light of day and the dark of night play important roles in setting our internal clocks. For years，researchers thought that the signals that synchronize the body's clock8were handled through the same pathways that we use to see.But recent discoveries show that the human eye has two separate light-sensing systems. One system allows us to see. The second system tells our body whether it's day or night.词汇：circadian/s3:'keidiən/ adj. 昼夜节奏的，生理节奏的adolescent/ædəu'lesənt/ n．青少年；adj．青少年的puberty/ 'pju:bəti/ n．发育；青春期sync/siŋk/ n. （口语）同步；和谐，协调synchronize/'siŋkrənaiz / V.（使）同时发生；（使）同步注释：1.make light of ：轻视，不在乎。

The discovery of a sort of life was announced after researchers at the US space agency,NASA3,analyzed data from spacecraft Cassini4,which pointed to,the existence of methane-based form of life on Saturn's biggest moon.Scientists have reportedly discovered clues showing primitive alien beings are"breathing" in Titan's dense atmosphere filled with hydrogen.They argue that hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane lakes and rivers. This,they say,points to the existence of some"bugs"5 consuming the hydrogen at the surface of the moon less than half the size of the Earth."We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan,similar to the way we consume oxygen on Earth,"says NASA scientist Chris McKay."If these signs do turn out to be a sign of life,it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth."To date,scientists have not yet detected this form of life anywhere,though there are liquid-water-based microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan, where temperatures are around 90 Kelvin6(minus 290 degrees Farenheit),a methanebased organism would have to use a substance that is liquid as its medium for living processes, but not water itself. Water is frozen solid on Titan's surface and much too cold to support life as we know it.Scientists had expected the Sun's interactions with chemicals in the atmosphere to produce a coating of acetylene on Titan's surface. But Cassini detected no acetylene on the surface.The absence of detectable acetylene on the Titan's surface can very well have a non-biological explanation,said Mark Allen,a principal investigator7 of the NASA Titan team."Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed,"Allen said. "We have a lot of work to do to rule out8 possible non-biological explanations. It is more likely that a chemical process,without biology,can explain these results."词汇：Saturn n．土星methane n．甲烷，沼气Titan n．土卫六acetylene n．乙炔alien n．外星人；adj．外星球的；相异的conservatism n．保守主义,守旧注释：1.hints of alien life：外星生命迹象。

+12 Dreams（新增）Everyone can dream．Indeed, everyone does dream．Those who claim that they never dream at all actually dream just as frequently as the rest of us, though they may not remember anything about it．Even those of us who are perfectly aware of dreaming night after night very seldom remember those dreams in great detail but merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our senses , so that we appear to experience sound, touch, smell, and taste．One of the world's oldest known written documents is the Egyptian Book of Dreams．This volume is about five thousand years old, so you can see that dreams were believed to have a special significance even then．Many ancient civilizations believed that you should never ask a sleeping person as, during sleep, the soul had left the body and might not be able to return in time if the sleeper were suddenly awoken .From ancient times to the present day ,people have been making attempts to interpret dreams and to explain their significance．There are many books available on the subject of dream interpretation．although unfortunately there are almost as many meanings for a particular dream as there are books．+14 A Health Profile （新增）A Health profile is a portrait of all of the factors that influence your health．To draw your health profile，you will need to know what diseases run in your family，what health hazards you may be exposed to at work,ow your daily diet compares to the recommended standards，how nluch time per week you spend exercising and what type of exercise you engage in ,how stressful your work and family environments are，what kinds of illnesses you get regularly,and whether or not you have any one of a number of addictions. To complete this portrait,you should have a checkup to determine how your blood，heart，and lungs are functioning.This checkup will serve as a baseline,to which you can then compare later tests．Once this profile is thoroughly drawn，you can begin to think about setting health priorities based on your particular portrait．For example，if you drink two martinis every evening,have a high-stress job ,are overweight，smoke a pack of cigarettes a day,and use marijuana occasionally on weekends，you should quit smoking first，followed by losing the excess weight，reducing the stress of your job，giving up your marihuana habit，and then finally giveing some thought to those martinis if you want to prevent first cancer，and then heart disease．Even for the youthful working person who has never been sick a day in his life,who is in excellent health．a good look at all health habits and at work and home environments may suggest changes that will benefit him in the future．+15 Life Expectancy in the Last Hundred Years （新增）A hundred years ago，life expectancy in developed countries was about 47: in the early 21st century, men in the United States and the United Kingdom can expect to live to about 74. Women to about 80, and these ages are rising all the time. What has brought about these changes? When we look at the life span of people l00 years ago, we need to look at the greatest killers of the time. In the early 20th century, these were the acute and often highly infectious diseases such as smallpox. Many children died very young from these diseases and others, and the weak and elderly were always at risk.In the developed world these diseases are far lessdeadly today, and in some cases have almost disappeared. A number of factors shave led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which make bacterial diseases much less dangerous, and vaccinations against common diseases. In addition, people's general health has improved with improvements in our general environment: cleaner air, better means of preserving food，better and warmer housing，and better understanding of nutrition.Genetically，we should all be able to live to about 85 but while people do live longer today, there are still some big killers around that are preventing US from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those spread by viruses, such as influenza and AIDS l. Of course, cancer is a huge killer as well. In most cases these diseases affect older people, but there are worrying trends in the developed world with problems such as obesity leadingto more heart disease and illnesses such as diabetes at younger ages.The killers today can be classed as "lifestyle diseases"，which means that it may be possible to halt their progress.第三十四篇谁想永生？如果你的医生能给你一种药，这个药能让你健康的活两倍长的时间，你会服用吗？好消息是我们离这一天越来越近了。

*第三＋八篇"Life Form Found" on Saturn's Titan Scientists say they have discovered hints of alien life1 on the Saturn's moon2. The discovery of a sort of life was announced after researchers at the US space agency,NASA3,analyzed data from spacecraft Cassini4,which pointed to,the existence of methane-based form of life on Saturn's biggest moon.Scientists have reportedly discovered clues showing primitive alien beings are"breathing" inTitan's dense atmosphere filled with hydrogen.They argue that hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane lakes and rivers. This,they say,points to the existence of some"bugs"5 consuming the hydrogen at the surface of the moon less than half the size of the Earth."We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan,similar to the way we consume oxygen on Earth,"says NASA scientist Chris McKay."If these signs do turn out to be a sign of life,it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth."To date,scientists have not yet detected this form of life anywhere,though there are liquid-water-based microorganisms on Earth that grow well on methane or produce it as a waste product.

+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.
