雅思英语阅读练习题及答案
雅思英语阅读练习题及答案：第一篇内容摘要：The failure of a high-profile cholesterol drug has thrown a spotlight on the complicated machinery that regulates cholesterol levels.★Why did a promising heart drug fail?Doomed drug highlights complications of meddling with cholesterol.1. The failure of a high-profile cholesterol drug has thrown a spotlight on the complicated machinery that regulates cholesterol levels. But many researchers remain confident that drugs to boost levels of 'good' cholesterol are still one of the most promising means to combat spiralling heart disease.2. Drug company Pfizer announced on 2 December that it was cancelling all clinical trials of torcetrapib, a drug designed to raise heart-protective high-density lipoproteins (HDLs). In a trial of 15000 patients, a safety board found that more people died or suffered cardiovascular problems after taking the drug plus a cholesterol-lowering statin than those in a control group who took the statin alone.3. The news came as a kick in the teeth to many cardiologists because earlier tests in animals and people suggested it would lower rates of cardiovascular disease. "There have been no red flags to my knowledge," says John Chapman, a specialist in lipoproteins and atherosclerosis at the National Institute for Health and Medical Research (INSERM) in Paris who has also studied torcetrapib. "This cancellation came as a complete shock."4. Torcetrapib is one of the most advanced of a new breed of drugs designed to raise levels of HDLs, which ferry cholesterol out of artery-clogging plaques to the liver for removal from the body. Specifically, torcetrapib blocks a protein called cholesterol ester transfer protein (CETP), which normally transfers the cholesterol from high-density lipoproteins to low density, plaque-promoting ones. Statins, in contrast, mainly work by lowering the 'bad' low-density lipoproteins.Under pressure5. Researchers are now trying to work out why and how the drug backfired, something that will not become clear until the clinical details are released by Pfizer. One hint lies in evidence from earlier trials that it slightly raises blood pressure in some patients. It was thought that this mild problem would be offset by the heart benefits of the drug. But it is possible that it actually proved fatal in some patients who already suffered high blood pressure. If blood pressure is the explanation, it would actually be good news for drug developers because it suggests that the problems are specific to this compound. Other prototype drugs that are being developed to block CETP work in a slightly different way and might not suffer the same downfall.6. But it is also possible that the whole idea of blocking CETP is flawed, says Moti Kashyap, who directs atherosclerosis research at the VA Medical Center in Long Beach, California. When HDLs excrete cholesterol in the liver, they actually rely on LDLs for part of this process. So inhibiting CETP, which prevents the transfer of cholesterol from HDL to LDL, might actually cause an abnormal and irreversibleaccumulation of cholesterol in the body. "You're blocking a physiologic mechanism to eliminate cholesterol and effectively constipating the pathway," says Kashyap.Going up7. Most researchers remain confident that elevating high density lipoproteins levels by one means or another is one of the best routes for helping heart disease patients. But HDLs are complex and not entirely understood. One approved drug, called niacin, is known to both raise HDL and reduce cardiovascular risk but also causes an unpleasant sensation of heat and tingling. Researchers are exploring whether they can bypass this side effect and whether niacin can lower disease risk more than statins alone. Scientists are also working on several other means to bump up high-density lipoproteins by, for example, introducing synthetic HDLs. "The only thing we know is dead in the water is torcetrapib, not the whole idea of raising HDL," says Michael Miller, director of preventive cardiology at the University of Maryland Medical Center, Baltimore.(613 words nature)Questions 1-7This passage has 7 paragraphs 1-7.Choose the correct heading for each paragraph from the list of headings below.

Time to cool itFrom The Economist print edition1 REFRIGERATORS are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want to cool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them.2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it will cool down.3 Someone who is looking at this inverse effect is Alex Mischenko, of Cambridge University. Using commercially available paraelectric film,he and his colleagues have generated temperature drops five times bigger than any previously recorded. That may be enough to change the phenomenon from a laboratory curiosity to something with commercial applications.4 As to what those applications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up a company to pursue them. He foresees putting his discovery to use in more efficient domestic fridges and air conditioners. The real money, though, may be in cooling computers.5 Gadgets containing microprocessors have been getting hotter for a long time. One consequence of Moore's Law, which describes the doubling of the number of transistors on a chip every 18 months, is that the amount of heat produced doubles as well. In fact, it more than doubles, because besides increasing in number, the components are getting faster. Heat is released every time a logical operation is performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples the heat output. And the frequency has doubled a lot. The first Pentium chips sold by Dr Moore's company, Intel, in 1993, ran at 60m cycles a second. The Pentium 4--the last "single-core" desktop processor--clocked up 3.2 billion cycles a second.6 Disposing of this heat is a big obstruction to further miniaturisation and higher speeds. The innards of a desktop computer commonly hit 80℃. At 85℃, they stop working. Tweaking the processor's heat sinks (copper or aluminium boxes designed to radiate heat away) has reached its limit. So has tweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems that divided processing power between first two, and then four, subunits, in order to spread the thermal load, also seems to have the endof the road in sight.7 One way out of this may be a second curious physicalphenomenon, the thermoelectric effect. Like paraelectric materials, this generates electricity from a heat source and produces cooling from an electrical source. Unlike paraelectrics, a significant body of researchers is already working on it.8 The trick to a good thermoelectric material is a crystal structure in which electrons can flow freely, but the path of phonons--heat-carrying vibrations that are larger than electrons--is constantly interrupted. In practice, this trick is hard to pull off, and thermoelectric materials are thus less efficient than paraelectric ones (or, at least, than those examined by Dr Mischenko). Nevertheless, Rama Venkatasubramanian, of Nextreme Thermal Solutions in North Carolina, claims to have made thermoelectric refrigerators that can sit on the back of computer chips and cool hotspots by 10℃. Ali Shakouri, of the University of California, Santa Cruz, says his are even smaller--so small that they can go inside the chip.9 The last word in computer cooling, though, may go to a system even less techy than a heat pump--a miniature version of a car radiator. Last year Apple launched a personal computer that is cooled by liquid that is pumped through little channels in the processor, and thence to a radiator, where it gives up its heat to the atmosphere. To improve on this, IBM's research laboratory in Zurich is experimenting with tiny jets that stir the liquid up and thus make sure all of it eventually touches the outside of the channel--the part where the heat exchange takes place. In the future, therefore, a combination of microchannels and either thermoelectrics or paraelectrics might cool computers. The old, as it were, hand in hand with the new.(830 words)Questions 1-5Complete each of the following statements with the scientist or company name from the box below.Write the appropriate letters A-F in boxes 1-5 on your answer sheet.A.

文章分析：Rainwater harvestingFor two years southern Sri Lanka suffered a prolonged drought, described by locals as the worst in 50 years. Some areas didnt see a successful crop for four or five consecutive seasons. Livestock died，water in wells dropped to dangerously low levels, children were increasingly malnourished and school attendance has fallen. Anestimated 1.6 million people were affected.A Muthukandiya is a village in Moneragaladistrict, one of the drought-stricken areas in the dry zone of southern Sri Lanka (斯里兰卡), where half the countrys population of18 million lives. Rainfall in the area varies greatly from year to year, often bringing extreme dry spells inbetween monsoons (季风).But this drought was much worse than usual. Despite some rain inNovember, only half of Moneragalas 1,400 tube wells were in workingorder by March. The drought devastated supplies of rice and freshwaterfish, the staple diet of inland villages. Many local industries closed downand villagers headed for the towns in search of work.B The villagers of Muthukandiya arrived in the 1970s as part of agovernment resettlement scheme. Each family was given six acres of land,with no irrigation system. Because crop production, which relies entirelyon rainfall, is insufficient to support most families, the village economyrelies on men and women working as day-labourers in nearby sugar-caneplantations. Three wells have been dug to provide domestic water, butthese run dry for much of the year. Women and children may spendseveral hours each day walking up to three miles (five kilometres) to fetchwater for drinking, washing and cooking.(部分文章节选)雅思阅读真题题目解析：rainwater harvestingQ1-6: 简答题( NO MORE THAN THREE WORDS)1.

Learning how to make smart financial decisions. And that's too bad, say experts, as that's exactly what all students need to focus on. Millennials(千禧⼀代), perhaps not surprisingly, are not very savvy(精明的;精通的)about money. In fact, a recent study, Money Matters on Campus, found that since 2012 students are less likely to follow a budget, pay credit card bills on time and infull, balance their checkbooks every month or buy only the things they need. The study, which surveyed 42,000 college freshmen across theU.S.,was conducted by education technology company EverFi and sponsored by Higher One, a financial services company serving college students. College students know they could do better. When it comes to grading(评分) how they manage their money, half give themselves a lukewarm(不温不⽕的) "C," according to a 2015 U.S. Bank survey of 1,640. "Most of these kids come from homes whose parents don’t possess any kind of plan for the money except planning their next vacation or doing Christmas," says Jim Chilton,CEO of the non-profit Society for Financial Awareness.(⾮营利性的⾦融意识社团总裁Jim Chilton说，“这些孩⼦的⽗母除了计划下⼀次的旅⾏和过圣诞，花钱⼤都没有什么计划。

ClassroomPassage 2：新冰河时代A New Ice AgeAWilliam Curry is a serious, sober climate scientist, not an art critic .But he has spent a lot of time perusing Emanuel Gottlieb Leutze’s famous painting “George Washington Crossing the Delaware,” which depicts a boatload of colonial American soldiers making their way to attack English and Hessian troops the day after Christm as in 1776. “Most people think these other guys in the boat are rowing, but they are actually pushing the iceaway,” says Curry, tapping his finger on a reproduction of the painting. Sure enough, the lead oarsman is bashing the frozen river with his boot. “I grew up in Philadelphia. The place in this painting is 30 minutes away by car. I can tell you, this kind of thing just doesn’t happen anymore.”BBut it may again soon. And ice-choked scenes, similar to those immortalized by the 16th-century Flemish painter Pieter Brueghel the Elder, may also return to Europe. His works, including the 1565 masterpiece “Hunters in the Snow,” make the now-temperate European landscapes look more like Lapland. Such frigid settings were commonplace during a period dating roughly from 1300 to 1850 because much of North America and Europe was in the throes of a little ice age. And now there is mounting evidence that the chill could return. A growing number of scientists believe conditions are ripe for another prolonged cool down, or small ice age. While no one is predicting a brutal ice sheet like the one that covered the Northern Hemisphere with glaciers (n. 冰川) about 12,000 years ago, the next cooling trend could drop average temperatures 5 degrees Fahrenheit over much of the United States and 10 degrees in the Northeast, northern Europe, and northern Asia.C“It could happen in 10 years,” says Terrence Joyce, who chairs the Woods Hole Physical Oceanography Department. “Once it does, it can take hundreds of years to reverse.” An d he is alarmed that Americans have yet to take the threat seriously.DA drop of 5 to 10 degrees entails much more than simply bumping up the thermostat and carrying on. Both economicallyand ecologically, such quick, persistent chilling could have devast ating consequences. A 2002 report titled“Abrupt Climate Change: Inevitable Surprises,” produced by the National Academy of Sciences, pegged the cost from agricultural losses alone at $100 billion to $250 billion while also predicting that damage to ecologies could be vast and incalculable. A grim sampler: disappearing forests, increased housing expenses, dwindling freshwater, lower crop yields (n. 产量)，and accelerated species extinctions.EPolitical changes since the last ice age could make survival far mo re difficult for the world’s poor. During previous cooling periods, whole tribes simply picked up and moved south, but that option doesn’t work in the modern, tense world of closed borders. “T o the extent that abrupt climate change may cause rapid and extensive changes of fortune for those who live off the land, the inability to migrate may remove one of the major safety nets for distressed people,” says the report.FBut first things first. Isn’t the earth actually warming? Indeed it is, says Joyce. In his cluttered office, full of soft light from the foggy Cape Cod morning, he explains how such warming could actually be the surprising culprit of the next mini-ice age. The paradox is a result of the appearance over the past 30 years in the North Atlantic of huge rivers of fresh water the equivalent of a 10-foot-thick layer-mixed into the salty sea. No one is certain where the fresh torrents are coming from, but a prime suspect is melting (adj. 融化的) Arctic ice, caused by a buildup of carbon dioxide in the atmosphere that traps solar energy.GThe freshwater trend is major news in ocean-science circles. Bob Dickson, a British oceanographer who sounded an alarm at a February conference in Honolulu, has termed the drop in salinity and temperature in the Labrador Sea— a body of water between northeastern Canada and Greenland that adjoins the Atlantic”arguably the largest full-depth changes observed in the modern instrumental oceanographic record.”HThe trend could cause a little ice age by subverting the northern penetration of Gulf Stream waters. Normally, the Gulf Stream, laden with heat soaked up in the tropics, meanders up the east coasts of the United States and Canada. As it flows northward, the stream surrenders heat to the air. Because the prevailing North Atlantic winds blow eastward, a lot of the heat wafts to Europe. That’s why many scientists believe winter temperatures on the Continent are as much as 36 degrees Fahrenheit warmer than those in North America at the same latitude. Frigid Boston, for example, lies at almost precisely the same latitude as balmy Rome. And some scientists say the heat also warms Americans and Canadians. “It’s a real mistake to think of this solely as a European phenomenon,”says Joyce.IHaving given up its heat to the air, the now-cooler water becomes denser and sinks into the North Atlantic by a mile or more in a process oceanographers call thermohaline circulation. This massive column of cascading cold is the main engine powering a deepwater current called the Great Ocean Conveyor that snakes through all the world’s oceans. But as the North Atlantic fills with freshwater, it grows less dense, making thewaters carried northward by the Gulf Stream less able to sink. The new mass of relatively freshwater sits on top of the ocean like a big thermal blanket, threatening the thermohaline circulation. That in turn could make the Gulf Stream slow or veer southward. At some point, the whole system could simply shut down, and do so quickly. “There is increasing evidence that we are getti ng closer to a transition point, from which we can jump to a new state. Small changes, such as a couple of years of heavy precipitation or melting ice at high latitudes, could yield a big response,” says Joyce.J“You have all this freshwater sitting at hi gh latitudes, and it can literally take hundreds of years to get rid of it,” Joyce says. So while the globe as a whole gets warmer by tiny fractions of 1 degree Fahrenheit annually, the North Atlantic region could, in a decade, get up to 10 degrees colder. What worries researchers at Woods Hole is that history is on the side of rapid shutdown. They know it has happened before.Questions 14-1614 The writer mentions the paintings in the first two paragraphs to illustrateA that the two paintings are immortalizedB people’s different opinionsC a possible climate change happened 12,000 years agoD the possibility of a small ice age in the future.15 Why is it hard for the poor to survive the next cooling period?A because people can’t remove themselves from the major safety nets.B because politicians are voting against the movement.C because migration seems impossible for the reason of closed borders.D because climate changes accelerate the process of moving southward.16 Why is the winter temperature in continental Europe higher than that in NorthAmerica?A because heat is brought to Europe with the wind flow.B because the eastward movement of freshwater continues.C because Boston and Rome are at the same latitude.D because the ice formation happens in North America.Questions 17-21Match each statement with the correct person A-D in the box belowNB You may use any letter more than once.17 A quick climate change wreaks great disruption.18 Most Americans are not prepared for the next cooling period.19 A case of a change of ocean water is mentioned in a conference.20 Global warming urges the appearance of the ice age.21 The temperature will not drop to the same degree as it used to be.List of PeopleA Bob DicksonB Terrene JoyceC William CurryD National Academy of Science答案14-16 DCA 17-21 DBABC22. heat 23. denser 24.

雅思阅读练习题：Does online preschool program work?Preschool is good for children, but it’s expensive.Can 4-year-olds learn what they need to know for kindergarten by sitting in front of a computer for 15 minutes a day?Utah is betting they can. This year, more than 6,600 children across the state are learning by logging on to laptops at home in a taxpayer-funded online preschool program that is unlike any other.This is preschool without circle time on the carpet, free play with friends and real,live teachers.In online preschool, children navigate(航行)through a series of lessons, games and songs with the help of a computer mouse and two animated raccoons(浣熊)named Rusty and Rosy.The Obama administration last year awarded an $11.5 million grant to expand the online program into rural communities to study how well it prepares children for kindergarten.Schools in South Carolina are testing it, and Idaho lawmakers are considering a pilot program(试点项目).It’s a sign of the growing interest among educators in using technology to customize(定制)learning, even for the youngest children. It also gives children who might otherwise not get any preparation for elementary school a chance to experience an academic program. (这也给了那些上小学前原本可能没有任何准备的孩子一个机会来体验学习课程。

雅思阅读练习题：Why Hollywood refuses actors of color?Four of the year’s 25 top-grossing movies(票房收入的电影)star a minority in a leading role. All but two had white directors. And the number of minority actors forecasters expect to get Oscar nominations(提名)can be counted on one hand. (有望获得奥斯卡提名的少数族裔演员屈指可数。
) In the year since the Sony Pictures hack exposed racially insensitive emails and cast a spotlight on Hollywood’s diversity problem,movie studios have shown little progress in hiring more people of color for their casts and crews.The industry is ignoring a gold mine. Every year for the past half-decade,the average white American has bought a ticket to fewer films than the average black,Hispanic or Asian moviegoer,industry data shows. Though 37 percent of the U.S. population, minorities bought 46 percent of the $1.2 billion in tickets sold in the United States last year.Some of the year’s biggest surprises had diverse actors and small budgets but ended up dominating(控制)the silver screen. For five straight weeks ending in September,movies with predominately(占绝大多数地)black casts topped the box office(票房), including the Christian drama “War Room, ” thriller “The Perfect Guy” and rap biography “Straight Outta Compton, ” which has made $200 million on a $28 million budget to become the highest-grossing biopic of all time.More recently, “Creed, ” a “Rocky” spinoff starring Michael B. Jordan and directed by Ryan Coogler — both 20-something black men who led the 2013 critical darling “Fruitvale Station” — has triumphed with $72 million at the box office and one of the best opening weekends in the boxing franchise’s(连锁加盟店)40-year history.High-profile hires of actors such as Jordan in “Creed” and John Boyega in “Star Wars: The Force Awakens” have remained the exception in a Hollywood that has shown only stuttering(结巴的;不持续的)progress over the past year in getting more-diverse talent into blockbuster(大片) roles.

But their struggles are a lesson on how little we know about the minefield of "ethical" marketing.The Body Shop, along with the American ice cream maker Ben and Jerry's, was hailed as a new breed of green, or environmentally conscious, business.Ben and Jerry’sA Ben & jerry's offers a very sweet benefits package to employees. First, every one of the 700+ Ben & Jerry's workers is entitled to three free pints of ice cream,sorbet or frozen yogurt per day worked. (Some workers even use allotments of their free treats to barter for other goods and services in town such as haircuts). Beyond the freebies,personnel receives a 50% discount on the pany's frozen goodies, a 40% discount on merchandise and a further 30% break on non-Ben & Jerry's foods at pany outlets.B Workers are further entitled to be paid family leave and may take advantage of the Employee Stock Purchase Program to purchase pany stock (after six months with the organization) at a 15% discount. Beginning in 1998, 316 stock options are awarded to each worker (excludingdirectors and officers) and stock is also assigned to each employee's 401K plan at the end of the calendar year. These contributions are intended to achieve the pany's goal of linked prosperity, i.e. to assure that future prosperity is widely shared by all employees.C Other benefits include:Health insurance, including coverage for well baby-care and mammogramsLife insurance (twice the employee's annual salary)Dental insuranceLong-term disability plan paying 60% of salary six months after disability for duration of disability Short-term disability plan paying 60% of salary for six monthsMaternity leave with full pay for six weeks after deliveryThe Body ShopD History of The Body Shop Anita Roddick started The Body Shop with a mere ?4,000 and a dream. With over 1,900 stores in 50 countries. The Body Shop was founded in 1976in Brighton, England. From her original shop, which offered a line of 25 different lotions, creams, and oils, Roddick became the first suessful marketer of body care products that bined natural ingredients with ecologically-benign manufacturing processes. Her pany's refusal to testproducts on animals, along with an insistence on nonexploitative labor practices among suppliers around the world, appealed especially to upscale, mainly middleclass women, who were and have continued to be the pany's primary market As sales boomed, even the conservative financial markets approved of The Body Shop's impressive profit picture, and a public stock offering in 1984 was suessful. An expansion campaign followed. In 1988 the pany entered the U.S. market by opening a store in New York City, and by 1997 the pany boasted 1,500 stores, including franchises, in 47 countries. Anti-marketing seemed to be smart marketing, at least as far as The Body Shop was concerned.E Part of the secret of The Body Shop’s early suess was that it had created a market niche for itself. The pany was not directly peting against the traditional cosmetics panies, which marketed their products as fashion aessories designed to cover up flaws and make women look more like thefashion models who appeared in their lavish ads. Instead, The Body Shop offered a line of products that promised benefits other than appearance—healthier skin,for instance—rather than simply a better-looking plexion. The pany is known for pioneering the natural-ingredient cosmetic market and establishing social responsibility as an integral part of pany operations. The Body Shop is knownfor its ethical stances, such as its moary donations to the munities in which it operates, and its business partnerships with developing countries. In 1988 Roddick opened her first store in the United States, and by that time—through various social initiatives such as the "Stop the Bum" campaign to save the Brazilian rainforest (the source of many of the pany's natural ingredients，and strong support of employee volunteerism——The Body Shop name had bee synonymous with social activism and global preservation worldwide. The pany had also bee immensely profitable.F By the mid-1990s, however. The Body Shop faced growing petition, forcing it to begin its first major advertising initiative, the most prominent part of which was the “Ruby” campaign. The campaign was personified by Ruby, a doll with Rubenesque proportions who was perched on an antique couch and who looked quite pleased with herself and her plump frame. Randy Williamson, a spokesperson for The Body Shop, said, “Ruby is the fruit of our long-established practice of challenging the way the cosmetic industry talks to women. The Ruby campaign is designed to promote the idea that The Body Shop creates products designed to enhance features, moisturize, cleanse, and polish, not to correct ‘flaws’. The Body Shop philosophyis that there is real beauty in everyone. We are not claiming that our products perform miracles."G The Competition the Body Shop lost market share in the late 1990’s to product-savvy petitors that offered similar cosmetics at lower prices. The main petitors areH20, Sephora, Bath and Body Works, and Origins. Research Results Research showed that women appreciate The Body Shop for its ethical standards. They are pleased by panies with green actions, not promises. The research proved that The Body Shop has been put on the back burner in many people's minds: overcrowded by newer, fresher Brands Companies like the Body Shop continually hype their products through advertising and marketing, often creating a demand for something where a real need for it does not exist. The message pushed is that the route to happiness is through buying more and more of their products. Under such consumerism, the increasing domination of multinationals and their standardised products is leading to global cultural conformity. Other downfall factors also include misleading the public, low pay and against unions, exploiting indigenous people ; Also the mass production, packaging and transportation of huge quantities of goods is using up the world's resources faster than they can be renewed and filling the land, sea and air with dangerous pollution and waste.H The Problem The Body Shop has used safe and timid advertising over the last decade, decreasing market share and brand value. With the rise of new, more natural and environmentally friendly petitors, The Body Shop can no longer stand behind being the greenest or most natural. The Solution The Body Shop is the originator of ethical beauty with our actions speaking louder than our words. This is the new direction of The Body Shop. We will be a part of different acts of kindness in big cities. We will eliminate unwanted graffiti, purify city air, and give the customer an opportunity to be a part of something good.Questions 1-4The reading Passage has seven paragraphs A-H.Which paragraph contains the following information?Write the correct letter A-H, in boxes 1-4 your answer sheet.1 An action taken to Establishing social responsibility in conservation project2 a description of the conventional way the ads applied to talk to its customers3 A history of a humble origin and expansion4 management practices arc intended to lined up the pany's goal with participants' prosperityQuestions 5-7Choose the three correct letter, A- F.Write your answers in boxes 5-7 on your answer sheet.5-7) What are true about the Ben & Jerry's pany managementA There was little difference between the highest salary and the lowestB They were advertising their product with powerful internal marketing.C They offer the employee plimentary productD Employee were encouraged to give services back to the munityE the products are designed for workers to barter for other goods and servicesF offered a package of benefits for disable employeesQuestions 8-10Choose the three correct letter, A- F.Write your answers in boxes 8-10 on your answer sheet.What are the factors once contributed to the suess for the BODY SHOP ?A pioneering the natural-ingredient cosmetics marketB appealed to primary market mainly of the rich womenC focused on their lavish ads campaignD The pany avoided producing the traditional cosmetics productsE its moral concept that refuses to use animals- tested ingredientsF its moary donations to the munities and in developing countriesQuestions 11-13Choose the three correct letter, A- F.Write your answers in boxes 11-13 on your answer sheet.What arc the factors leading to the later failure for BODY SHOP pany?A its philosophy that there is real beauty in everyone is faultyB fail to fulfill promises while acted like misleading the publicC faced growing petitionD its creating demand for something that the customers do not actually needE its newer, fresher Brands are not suessful in the MarketF fail to offer cosmetics at lower prices than petitors文章题目：营销的新概念篇章结构体裁论说文题目营销的新概念结构 A段：Ben & Jerry为员工提供商品和折扣福利B段：Ben & Jerry为员工提供带薪探亲假和股票购置优惠C段：Ben & Jerry为员工提供的其他福利D段：The Body Shop的开展历程和营销策略E段：The Body Shop早期成功的秘诀F段：The Body Shop为应对竞争，发起名为Ruby的运动G段：The Body Shop衰落的因素H段：The Body Shop存在的问题和解决方法题目类型：LIST OF HEADINGS题号定位词文中对应点题目解析1 Establishing social responsibilities E段第四句 E段第四句提到The pany is know for… and establishing social responsibility as an integral part of pany operations.因此，此题答案为E。
雅思阅读考试模拟试练习题及答案解析
雅思阅读考试模拟试练习题及答案解析Time to cool itFrom The Economist print edition1 REFRIGERATORS are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want tocool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them.2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it will cool down.3 Someone who is looking at this inverse effect is Alex Mischenko, of Cambridge University. Using commercially available paraelectric film, he and his colleagues have generated temperature drops five times bigger than any previously recorded. That may be enough to change the phenomenon from a laboratory curiosity to something with commercial applications.4 As to what those applications might be, Dr Mischenko is still a little hazy. He has, nevertheless, set up a company to pursue them.He foresees putting his discovery to use in more efficient domestic fridges and air conditioners. The real money, though, may be in cooling computers.5 Gadgets containing microprocessors have been getting hotter fora long time. One consequence of Moore's Law, which describes the doubling of the number of transistors on a chip every 18 months, is that the amount of heat produced doubles as well. In fact, it more than doubles, because besides increasing in number, the componentsare getting faster. Heat is released every time a logical operationis performed inside a microprocessor, so the faster the processor is, the more heat it generates. Doubling the frequency quadruples theheat output. And the frequency has doubled a lot. The first Pentium chips sold by Dr Moore's company, Intel, in 1993, ran at 60m cycles a second. The Pentium 4--the last "single-core" desktop processor--clocked up 3.2 billion cycles a second.6 Disposing of this heat is a big obstruction to further miniaturisation and higher speeds. The innards of a desktop computer commonly hit 80℃. At 85℃, they stop working. Tweaking theprocessor's heat sinks (copper or aluminium boxes designed to radiate heat away) has reached its limit. So has tweaking the fans that circulate air over those heat sinks. And the idea of shifting from single-core processors to systems that divided processing power between first two, and then four, subunits, in order to spread the thermal load, also seems to have the end of the road in sight.7 One way out of this may be a second curious physical phenomenon, the thermoelectric effect. Like paraelectric materials, thisgenerates electricity from a heat source and produces cooling from an electrical source. Unlike paraelectrics, a significant body of researchers is already working on it.8 The trick to a good thermoelectric material is a crystal structure in which electrons can flow freely, but the path ofphonons--heat-carrying vibrations that are larger than electrons--is constantly interrupted. In practice, this trick is hard to pull off, and thermoelectric materials are thus less efficient thanparaelectric ones (or, at least, than those examined by Dr Mischenko). Nevertheless, Rama Venkatasubramanian, of Nextreme Thermal Solutionsin North Carolina, claims to have made thermoelectric refrigerators that can sit on the back of computer chips and cool hotspots by 10℃. Ali Shakouri, of the University of California, Santa Cruz, says his are even smaller--so small that they can go inside the chip.9 The last word in computer cooling, though, may go to a system even less techy than a heat pump--a miniature version of a car radiator. Last year Apple launched a personal computer that is cooled by liquid that is pumped through little channels in the processor,and thence to a radiator, where it gives up its heat to the atmosphere. To improve on this, IBM's research laboratory in Zurichis experimenting with tiny jets that stir the liquid up and thus make sure all of it eventually touches the outside of the channel--thepart where the heat exchange takes place. In the future, therefore, a combination of microchannels and either thermoelectrics or paraelectrics might cool computers. The old, as it were, hand in hand with the new.(830 words)Questions 1-5Complete each of the following statements with the scientist or company name from the box below.Write the appropriate letters A-F in boxes 1-5 on your answer sheet.A.

However, psychologists differentiate between levels of happiness. The most immediate type involves a feeling; pleasure or joy. But sometimes happiness is a judgment that life is satisfying, and does not imply an emotional state. Esteemed psychologist Martin Seligman has spearheaded an effort to study the science of happiness. The bad news is that we’re not wired to be happy. The good news is that we can do something about it. Since its origins in a Leipzig laboratory 130 years ago, psychology has had little to say about goodness and contentment. Mostly psychologists have concerned themselves with weakness and misery. There are libraries full of theories about why we get sad, worried, and angry. It hasn’t been respectable science to study what happens when lives go well. Positive experiences, such as joy, kindness, altruism andheroism, have mainly been ignored. For every 100 psychology papers dealing with anxiety or depression, only one concerns a positive trait.BA few pioneers in experimental psychology bucked the trend. Professor Alice Isen of Cornell University and colleagues have demonstrated how positive emotions make people think faster and more creatively. Showing how easy it is to give people an intellectual boost, Isen divided doctors making a tricky diagnosis into three groups: one received candy, one read humanistic statements about medicine, one was a control group. The doctors who had candy displayed the most creative thinking and worked more efficiently. Inspired by Isen and others, Seligman got stuck in. He raised millions of dollars of research money and funded 50 research groups involving 150 scientists across the world. Four positive psychology centres opened, decorated in cheerful colours and furnished with sofas and baby-sitters. There were get-togethers on Mexican beaches where psychologists would snorkel and eat fajitas, then form “pods” to discuss subjects such as wonder and awe. A thousand therapists were coached in the new science.CBut critics are demanding answers to big questions. What is the point of defining levels of happiness and classifying the virtues? Aren’t these concepts vague and impossible to pin down? Can you justifyspending funds to research positive states when there are problems such as famine, flood and epidemic depression to be solved? Seligman knows his work can be belittled alongside trite notions such as “the power of positive thinking”. His plan to stop the new science floating “on the waves of self- improvement fashions” is to make sure it is anchored to positive philosophy above, and to positive biology below.DAnd this takes us back to our evolutionary past. Homo sapiens evolved during the Pleistocene era (1.8 m to 10,000 years ago), a time of hardship and turmoil. It was the Ice Age, and our ancestors endured long freezes as glaciers formed, then ferocious floods as the ice masses melted. We shared the planet with terrifying creatures such as mammoths, elephant-sized ground sloths and sabre-toothed cats. But by the end of the Pleistocene, all these animals were extinct. Humans, on the other hand, had evolved large brains and used their intelligence to make fire and sophisticated tools, to develop talk and social rituals. Survival in a time of adversity forged our brains into a persistent mould. Professor Seligman says: “Because our bra in evolved during a time of ice, flood and famine, we have a catastrophic brain. The way the brain works is looking for what’s wrong. The problem is, that worked in the Pleistocene era. It favoured you, but it doesn’t work in the modem world.”EAlthough most people rate themselves as happy, there is a wealth of evidence to show that negative thinking is deeply ingrained in the human psyche. Experiments show that we remember failures more vividly than successes. We dwell on what went badly, not what went well. Of the six universal emotions, four anger, fear, disgust and sadness are negative and only one, joy, is positive. The sixth, surprise, is psychologist Daniel Nettle, author of Happiness, and one of the Royal Institution lecturers, the negative em otions each tell us “something bad has happened” and suggest a different course of action.FWhat is it about the structure of the brain that underlies our bias towards negative thinking? And is there a biology of joy? At Iowa University, neuroscientists studied what happens when people are shown pleasant and unpleasant pictures. When subjects see landscapes or dolphins playing, part of the frontal lobe of the brain becomes active. But when they are shown unpleasant images a bird covered in oil, or a dead soldier with part of his face missing the response comes from more primitive parts of the brain. The ability to feel negative emotions derives from an ancient danger-recognition system formed early in the brain’s evolution. The pre-frontal cortex, which registers happiness, is the part used for higher thinking, an area that evolved later in human history.GOur difficulty, according to Daniel Nettle, is that the brain systems for liking and wanting are separate. Wanting involves two ancient regions the amygdala and the nucleus accumbens that communicate using the chemical dopamine to form the brain’s reward system. They are involved in anticipating the pleasure of eating and in addiction to drugs. A rat will press a bar repeatedly, ignoring sexually available partners, to receive electrical sti mulation of the “wanting” parts of the brain. But having received brain stimulation, the rat eats more but shows no sign of enjoying the food it craved. In humans, a drug like nicotine produces much craving but little pleasure.HIn essence, what the biology lesson tells us is that negative emotions are fundamental to the human condition, and ifs no wonder they are difficult to eradicate. At the same time, by a trick of nature, our brains are designed to crave but never really achieve lasting happiness.Question 14-20The reading passage has seven paragraphs A-H.Which paragraph contains the following information?Write the correct letter A-H, in boxes 14-20 on your answer sheet.14 An experiment involving dividing several groups one of which received positive icon15 Review of a poorly researched psychology area16 Contrast being made about the brain’s action as response to positive or negative stimulus17 The skeptical attitude toward the research seemed to be a waste of fund18 a substance that produces much wanting instead of much liking19 a conclusion that lasting happiness are hardly obtained because of the nature of brains20 One description that listed the human emotional categoriesQuestion 21-25Complete the following summary of the paragraphs of Reading Passage, using no more than four words from the Reading Passage for each answer.Write your answers in boxes 21-25 on your answer sheet.A few pioneers in experimental psychology study what happens when lives go well.
