The study, published in the Journal of Animal Ecology, found that ants have two distinct effects on their local environment.……………………………………段落省洛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 processes8through the alteration of the physical and chemical environment and through their effects on plants, microorganisms, and other soil organisms.练习：1 .Why are ants compared to ecosystem engineers?C 、Because their activity affects the environment.2. As predators, antsA 、prey on small as well as large animals.3. Dir Sanders' study centered on how antsD produce such a big impact on the environment.4. What does paragraph 6 tell us?B 、Ants bring about a positive influence to an area when their population is small.5. What still remains unclear about ants, according to the last paragraph?C How do human activities affect ants' influence on a given ecosystem?完形填空第三篇Germs on BanknotesPeople in different countries use different types of 1、money yuan in China, pesos in Mexico, pounds in the United Kingdom, dollars in the United States, Australia and New Zealand. They may use 2、different 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、century , 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、within one country. In a new study, Frank Vriesekoop3 and other researchers compared the germ populations found on bills of different 5、countries .Vriesekoop3 is a microbiologist at the University of Ballarat in Australia4. He led the study, which compared the germ populations found on money 6、gathered from 10 nations. The scientists studied 1,280 banknotes intotal; all came from places where people buy food, like supermarkets street vendors and cafes, 7、because 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 not cause 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、cotton .Different countries may use different 9、materials to print their money. Some of the currencies studied by Vriesekoop and his 10、team such as the American dollar were made from cotton. Others were made from polymers.The three 11、currencies 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、mostly of cotton. Fewer germs lived on the polymer notes. This connection suggests that 13、germs 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、compare 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、hands after touching it; after all5, you never know where your money 's been. Or what's living on it注释：第十篇 Chicken Soup for the Soul：Comfort Food Fights Loneliness Mashed potatoes, macaroni and cheese, may be bad for your arteries．1、 but according to a study in Psychological Science, they’re good for your heart and2、emotions The study focuses on “comfort food” and how it makes people feel．"For me 3、personally ,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、looked at non-human things that may affect human emotions．Some people reduce loneliness by bonding with their 5、 favorite 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、by making peoplethink of their nearest and dearest. In one experiment, in order to make 7、participants 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、 group wrote about the experience of eating a comfort food and others wrote about eating a new food．9、Finally ,the researchers had participants 10、 complete questions about their levels of loneliness．Writing about a fight with a close person made people feel lonely．But people who were generally 11、secure 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、their essays on comfort food, many people wrote about the 13、experience of eating food with family and friends. In another experiment, 14、 eating 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、connections with others," Troisi says．"Comfort food Can be an easy remedy for loneliness．*第十一篇 Climate Change Poses Major Risks for Unprepared Cities （B级完型）A new examination of urban policies has been 1、carriedout recently by Patricia Romero Lankao．She is a sociologist specializing in climate change and 2 、urban 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、reduce emissions of carbon dioxide and other greenhouse 4、gases．These gases are known to affect the atmosphere．”Climate change is a deeply local issue and poses profound threats to the growing cities of the world,” says Romer o Lankao. ”But too few cities are developing effective strategies to 5、protect their residents."Cities are 6、major sources of greenhouse gases．And urban populations are likely to be among those most severely affected by future climate ch ange. Lankao’s findings highlight ways in which city-residents are particularly vulnerable, and suggest policy interventions that could offer immediate and longer-term 7 、benefits．The locations and dense construction patterns of cities often place their populations at greater risk for natural disasters. Potential 8、threats associated with climate include storm surges and prolonged hot weather. Storm surges can flood coastal areas and prolonged hot weather can heat 9、heavily paved cities more than surrounding areas．The impacts of such natural events can be more serious in an urban environment．For example，a prolonged heat wave can increaseexisting levels of air pollution，causing widespread health problems．Poorer neighborhoods that may 10、lack basic facilities such as drinking water or a dependable network of roads，are especially vulnerable to natural disasters．Many residents in poorer countries live in substandardhousing 11、without access to reliable drinking water，roads and basic services.Local governments, 12、therefore ,should take measures to protect their residents.”Unfortunately，they tend to move towards rhetoric 13、rather than meaningful responses, Romero Lankao writes, ” They don’t impose const ruction standards that could reduce heating and air conditioning needs. They don't emphasize mass transit and reduce 14 、 automobile use. In fact, many local governments aretaking a hands—off approach.” Thus, she urges themto change their 15 、idle policies and to take strong steps to prevent the harmful effects of climate change on cities.*第十二篇 Free Statins With Fast Food Could Neutralize Heart Risk（B 级完型）Fast food outlets could provide statin drugs free of 1、charge so that customers can reduce the heart disease dangers of fatty food, researchers at Imperial College London 2、suggest in a newstudy．Statins reduce the 3 、 amount 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 、risk .In a paper published in the American Journal of Cardiology，Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is 5、enough to offset the increase in heart attack risk from 6、eating a cheeseburger and drinking a milkshake．Dr Francis，from the National Heart and Lung Institute at Imperial College London，who is the senior author of the study, said:”Statins don’t cut out a11 of the 7、unhealthy 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、possibility of having a heart attack. Taking a statin can reduce your risk to more or less the same 9、degree 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、like , but statins, which are beneficial to heart health, have to be prescribed. It makes sense to make risk-reducing statins available just as easily as the unhealthy condiments that are 11、provided free of charge．It would cost less than 5 pence per 1 2、 customer 一not much different to a sachet of sugar.” Dr Francis s aid．When people engage in risky behaviours like driving or smoking, they’re encouraged to take 13、measures that lower their risk, 1ike 14 wearing a seatbelt or choosing cigarettes with filters. Taking a statin is a rational way of 1 5、lowering some of the risks of eating a fatty meal．+第十三篇Solar Power without Solar Cells（A级完型）A dramatic and surprising magnetic effect of light discovered by University of Michigan1researchers could lead to solar power without traditional semiconductor-based solar cells.The researchers found a way to make an "optical 1、battery ," 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 the2、effects 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、previously expected. 4、Under 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、light 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 power6、source."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 pulling7、apart of the positive and negative charges6 in a material. This sets up a voltage, similar to 8、that 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、material that does not 10、conduct 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、effective in producing charge separation as laser light is," Fisher said.This new 12、technique could make solar power cheaper, the researchers say. They predict that with improved materials they could achieve 10 percent efficiency in 13、converting solar power to useable energy. That's equivalent to today's commercial-grade solar cells."To manufacture 14 、modern 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、both . It's already made in bulk10, and it doesn't require as much processing. Transparent ceramics might be even better."+第十五篇“Liquefaction” Key to Much of Japanese Earthquake Damage（A级完型）The massive subduction zone1earthquake in Japan caused a significant level of soil"liquefaction"2 that has surprised researchers with its 1、widespread severity, a new analysis shows."We've seen localized3 examples of soil liquefaction as extreme as this before, but the distance and 2、extent 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、function . We saw some places that sank as much as four feet."Some degree of soil liquefaction7is 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 、strength and flowduring an earthquake. This can allow structures to shift or sink or 5、collapse .But most earthquakes are much 6、shorter 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、how 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、recently f illed 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、phenomenon and better prepare for it in the future. Ashford said it was critical for the team to collect the information quickly, 10、before damage was removed in the recovery efforts9."There's no doubt that we'll learn things from what happened in Japan10 that11will help us to reduce risks in other similar 11、events ," 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、deposited 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、near 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、prevent collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction 15、standards helped prevent many buildings from collapse ---even as they tilted and sank into the ground.轻松词汇通轻轻松松词汇通，稳拿满分在其中一、解释版：（一）必记：10大词汇选项要求掌握的单词：（03年8对8分，04年8对8分，05年8对两半10分）（斜体部分为近两年已考）1\account for=explain 理解minute=slight 细小disorder=confusion混乱Accused of=charged with 指控investigate=look into 调查numerous=many 许多obvious=clear 显而易见Odd=strange 奇怪participate in=take part in 参加preserve=keep 保存previously=before以前pull up=stop 停止perceive=notice 注意到possess=own占有substantial=significant 实质的2\spur=encourage 激励coverage=reportage报道dimly=faintly 昏暗(048)，模糊mildly=gently 温和地inevitable=certain 不可避免isolate=solitary 孤立的call of=cancel取消make up one’s mind=decide决定Now and then=occasionally=sometimes 有时find fault with=criticize 批评grasp=take hold of抓住Consideration=account 考虑tolerate=put up with 忍受abandon=give up 放弃lately=recently最近3\Manual=physical 人工harness=utilise(utilize) 利用resident=occupant 居民steadily=continuously不断地Remedy=cure治疗(055)draft==formulate起草practically=almost 几乎endeavor=try=test尝试seldom=rarely 很少而精Readily=willingly 乐意shine=polish 擦亮Extract=take out 取出(045)decent=honest正派Lethal=Deadly=fatal 致命的4\insist on=demand 坚持speed=velocity快过Physician=doctor 医生particularly=especially特别safe=secure安全的branch=division分支机构Abnormal=unusual 不正常的accelerate=step up 加快abundant=plentiful 丰富的accumulate=collect积累Allocate=distribute=assign 分配childish=immature 幼稚barren=bare贫瘠5\appalling=dreadful讨厌的Anyhow=anyway 不管achieve=attain 通过努力达到capability=ability 能力in conjunction=together共同Credible=convincing 可信的diligent=hardworking 勤奋diverse=varied多种多样faulty=wrong有错的Gorgeous=lovely 极美的persist=continue 持续regulate=control 控制scatter=separate分开Stand point=point of view 观点touching=moving 感人的6\vanish=disappear消失phase=stage阶段Deter=inhibit=prevent 阻止porcelain=china 陶瓷prior to=before在。
