Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Passage 1Surviving the RecessionA)America’s recession began quietly at the end of 2007. Since then it has evolvedinto a global crisis. Reasonable people may disagree about whom to blame.Financiers who were not as clever as they thought they were? Regulators falling asleep at work? Consumers who borrowed too much? Politicians who thoughtlessly promoted home-ownership for those who could not afford it? All are guilt; and what a mess they have created.B)Since 2007 America has shed 5 million jobs. More than 15% of the workforce arejobless or underemployed—roughly 25 million workers. The only industries swelling their payrolls are health care, utilities and the federal government. The value of listed shares in American firms collapsed by 57% from its peak in October 2007 to a low in March this year, though it has since bounded back somewhat. Industrial production fell by 12.8% in the year to March, the worst slide since the Second World War. Mark Zandi, an economist at Moody’s Economy., predicts that the recession will shrink America’s economy by 3.5% in total. “For most executives, this is the worst business environment they’ve ever seen.”C)Times are so tough that even bosses are taking pay cuts. Median （中位数的）payfor chief executives of S&P 500 companies fell 6.8% in 2008. The overthrown business giants of Wall Street took the biggest knock, with average pay cuts of 38% and median bonuses of zero. But there was some pain for everyone: median pay for chief executives of non-financial firms in the S&P 500 fell by 2.7%.D)Nearly every business has a sad tale to tell. For example, Arne Sorenson, thepresident of Marriott hotel, likens the crisis to the downturn that hit his business after September 11th, 2001. When the twin towers fell, Americans stopped travelling. Marriott had its worst quarter ever, with revenues per room falling by 25%. This year, without a terrorist attack, the hotel industry is “putting the same numbers on the board”, says Mr. Sorenson.E)Other industries have suffered even more. Large numbers of builders, propertyfirms and retailers have gone bankrupt. And a disaster has hit Detroit. Last year the American car industry had the capacity to make 17 million vehicles. Sales in 2009 could be barely half of that. The Big Three American carmakers—General Motors, Ford and Chrysler—accumulated ruinous costs over the post-war years, such as gold-plated health plans and pensions for workers who retired as young as48. All three are desperately restructuring. Only Ford may survive in its currentform.F)Hard times breed hard feeling. Few Americans understand what caused therecession. Some are seeking scapegoats （替罪羊）. Politicians are happy to take advantage. Bosses have been summoned to Washington to be scolded on live television. The president condemns their greed.G)Business folks are bending over backwards to avoid seeming extravagant.Meetings at resorts are suddenly unacceptable. Goldman Sachs, an investment bank, cancelled a conference in Las Vegas at the last minute and rebooked it in San Francisco, which cost more but sounded less fun.H)Anyway, the pain will eventually end. American business will regain its shine.Many firms will die, but the survivors will emerge leaner and stronger than before.The financial sector’s share of the economy will shrink, and stay shrunk for years to come. The importance of non-financial firms will accordingly rise, along with their ability to attract the best talent. America will remain the best place on earth to do business, so long as Barack Obama and the Democrats in Congress resist the temptation to interfere too much, and so long as organized labors does not overplay its hand.I)Mr. Obama’s plan to curb carbon dioxide emissions （排放）, though necessary,will be far from cost-free, whatever his sunny speeches on the subject might suggest. The shift to a low-carbon economy will help some firms, hurt others and require every organization that uses much energy to rethink how it operates. It is harder to predict how Mr. Obama’s proposed reforms to the failing health-care system will turn out. If he succeeds in curbing costs—a big if—it would be a huge gain for America. Some business will benefit but the vast bulk of the savings will be captured by workers, not their employers.J)In the next couple of years the businesses that thrive will be those that are tight with costs, careful of debt, cautious with cash flow and extremely attentive to what customers want. They will include plenty of names no one has yet heard of. K)Times change, and corporations change with them. In 1955 Time’s Man of the Year was Harlow Curtice, the boss of GM. His firm was leading America towards “a new economic order”, the magazine wrote. Thanks to men like Curtice, “the bonds of scarcity” had been broken and America was rolling “to an all-time high of prosperity”. Soon, Americans would need to spend “comparatively little time earning a living”.L)Half a century later GM is a typical example for poor management. In March its chief executive was fired by Time’s current Man of the Year, Mr. Obama. The government now backs up the domestic car industry, lending it money and overseeing its turnaround plans. With luck, this will be short-lived. But there is a danger that Washington will end up micromanaging not only Detroit but also other parts of the economy. And clever as Mr. Obama’s advisers are, history suggests they will be bad at this.1.The America’s recession affected the hotel industry as badly as the 9/11 terroristattack.2.Businessmen are trying to avoid seeming wasteful in response to the recession.3.In the near future, a thriving business will go with cautious management tactics.4.Much doubt remains whether the Obama administration will do well inmicromanaging the America’s economy.5. A combination of causes is responsible for the current American recession, whichbegan in 2007.6.The government is not supposed to interfere too much in American businesses.7.The big Three American carmakers need restructuring to survive due to theiraccumulation of the ruinous costs over the post-war years.8.In March, GM”s chief executive was fired by Obama for poor management.9.According to the author, Obama’s plan to limit carbon dioxide emissions will byno means be inexpensive.10.At the worst time, the total value of listed shares in American firms shrank byfifty-seven percent.(D G J L A H E L I B)Passage twoSmall schools RisingA)This year’s list of the top 100 high schools shows that today, those with fewerstudents are flourishing.B)Fifty years ago, they were the latest thing in educational reform: big, modern,suburban high schools with students counted in the thousands. As baby boomers （二战后婴儿潮时期出生的人）came of high-school age, big schools promised economic efficiency. A greater choice of courses, and, of course, better football teams. Only years later did we understand the trade-offs this involved: the creation of excessive bureaucracies（官僚机构）,the difficulty of forging personal connections between teachers and students. SAT scores began dropping in 1963;today, on average, 30% of students do not complete high school in four years, a figure that rises to 50% in poor urban neighborhoods. While the emphasis on teaching to higher, test-driven standards as set in No Child Left Behind resulted in significantly better performance in elementary (and some middle) schools, high schools for a variety of reason seemed to have made little progress.C)Size isn’t everything, but it does matter, and the past decade has seen a noticeablecountertrend toward smaller schools. This has been due, in part, to the Bill and Melinda Gates Foundation, which has invested $1.8 billion in American high schools, helping to open about 1000 small schools—most of them with about 400 kids each, with an average enrollment of only 150 per grade. About 500 more are on the drawing board. Districts all over the county are taking notice, along with mayors in cities like New York, Chicago and San Diego. The movement includes independent public charter schools, such as No.1 BASIS in Tucson, with only 120 high-schools and 18 graduates this year. It embraces district-sanctioned magnet schools, such as the Talented and Gifted School, with 198 students, and theScience and Engineering Magnet, with 383, which share a building in Dallas, as well as the City Honors School in Buffalo, N.Y., which grew out of volunteer evening seminars for students. And it includes alternative schools with students selected by lottery（抽签）, such as H.B Woodlawn in Arlington, Va. And most noticeable of all, there is the phenomenon of large urban and suburban high schools that have split up into smaller units of a few hundred, generally housed in the same grounds that once boasted thousands of students all marching to the same band.D)Hillsdale High School in San Mateo, Calif., is one of those, ranking No. 423—among the top 2% in the country—on Newsweek’s annual ranking of America’s top high schools. The success of small schools is apparent in the listings. Ten years ago, when the first Newsweek list based on college-level test participation was published, only three of the top 100 schools had graduating classes smaller than 100 students. This year there are 22. Nearly 250 schools on the full Newsweek list of the top 5% of schools nationally had fewer than 200 graduates in 2007.E)Although many of Hillsdale’s students came from wealthy households, by the late1990 average test scores were sliding and it had earned the unaffectionate nickname “Hillsjail”. Jeff Gibert, a Hillsdale teacher who became principal last year, remembers sitting with other teachers watching students file out of a graduation ceremony and asking one another in astonishment, “How did that student graduated?”F)So in 2003 Hillsdale remade itself into three “houses”, romantically namedFlorence, Marrakech and Kyoto. Each of the 300 arriving ninth graders are randomly assigned to one of the houses, where they will keep the same four core subject teachers for two years, before moving on to another for 11th and 12th grades. The closeness this system cultivates is reinforced by the institution of “advisory” classes. Teachers meet with students in groups of 25, five mornings a week, for open-ended discussions of everything from homework problems to bad Saturday-night dates. The advisers also meet with students privately and stay in touch with parents, so they are deeply invested in the students’success. “We’re constantly talking about one another’s advisers,”says English teacher Chris Crockett. “If you hear that yours isn’t doing well in math, or see them sitting outside the dean’s office, it’s like a personal failure.” Along with the new structure came a more demanding academic program, the percentage of freshmen taking biology jumped from 17 to 95. “It was rough for some. But by senior year, two-thirds have moved up to physics,”says Gilbert. “Our kids are coming to school in part because they know there are adults here who know them and care for them.” But not all schools show advances after downsizing, and it remains to be seen whether smaller schools will be a cure-all solution.G)The Newsweek list of top U.S. high schools was made this year, as in years past,according to a single metric, the proportion of students taking college-level exams.Over the years the system has come in for its share of criticism for its simplicity.But that is also its strength: it’s easy for readers to understand, and to do thearithmetic for their own schools if they’d like.H)Ranking schools is always controversial, and this year a group of 38superintendents（地区教育主管）from five states wrote to ask that their schools be excluded from the calculation. “It is impossible to know which high schools are ‘the best’ in the nation,” their letter read, in part. “Determining whether different schools do or don’t offer a high quality of education requires a look at many different measures, including students’overall academic accomplishments and their subsequent performance in college. And taking into consideration the unique needs of their communities.”I)In the end the superintendents agreed to provide the data we sought, which is,after all, public information. There is, in our view, no real dispute here; we are all seeking the same thing, which is schools that better serve our children and our nation by encouraging students to make tough subjects under the guidance of gifted teachers. And if we keep working toward that goal, someday, perhaps a list won’t be necessary.1.In practical use, simplicity is still considered a strength of Newsweek’s schoolranking system in spite of the criticism it receives.2.As a result setting up big schools, students’ performance declined.3.Newsweek ranked high schools according to their college-level test participation.4.Half a century ago, big, modern, suburban high schools were established to ensureefficient education for baby boomers.5.It is agreed that qualified teachers, better services and encouragement are keys toreaching the ultimate goal of school education.6.The most noticeable trend in high school education is the splitting of large schoolsinto smaller ones.7.It is still unknown whether smaller schools will be a solution to all educationalproblems.8.High schools funded by the Bill and Melinda Gates Foundation are small in size.9.Different measures should be used in assessing the quality of school education.10.The “advisory”classes at Hillsdale were set up so that students could maintaincloser relationship with their teachers.(G B D B I C F C H F)Passage 3.HighwaysA)Early in the 20th century, most of the streets and roads in the U.S. were made ofdirt, brick, and cedar wood blocks. Built for horse, carriage, and foot traffic, they were usually poorly cared for and too narrow to accommodate（容纳）automobiles.B)With the increase in auto production, private turnpike（收费公路）companiesunder local authorities began to spring up, and by 1921 there were 387000 miles of paved roads. Many were built using specifications of 19th century Scottish engineers Thomas Telford and John MacAdam (for whom the macadam surface is named), whose specifications stressed the importance of adequate drainage.Beyond that, there were no national standards for size, weight restrictions, or commercial signs. During World War I. roads throughout the country were nearly destroyed by the weight of trucks. When General Eisenhower returned from Germany in 1919, after serving in the U.S. army’s first transcontinental motor convoy（车队）, he noted: “The old convoy had started me thinking about good, two-lane highways, but Germany’s Autobahn or motorway had made me see the wisdom of broader ribbons across the land.”C)It would take another war before the federal government would act on a nationalhighway system. During World War II, a tremendous increase in trucks and new roads were required. The war demonstrated how critical highways were to the defense effort. Thirteen percent of defense plants received all their supplies by truck, and almost all other plants shipped more than half of their products by vehicle. The war also revealed that local control of highways had led to a confusing variety of design standards. Even federal and state highways did not follow basic standards. Some states allowed trucks up to 36000 pounds, while others restricted anything over 7000 pounds. A government study recommended a national highway system of 33920 miles, and congress soon passed the Federal-Aid Highway Act of 1944, which called for strict, centrally controlled design criteria.D)The interstate highway system was finally launched in 1956 and has been hailedas one of the greatest public works projects of the century. To build its 44000-mile web of highways, bridges, and tunnels, hundreds of unique engineering designs and solutions had to be worked out. Consider the many geographic features of the country: mountains, steep grades, wetlands, rivers, deserts and plains. Variables included the slope of the land, the ability of the pavement to support the load, the intensity of road use, and the nature of the underlying soil. Urban areas were another problem. Innovative designs of roadways, tunnels, bridges, overpasses, and interchanges that could run through or bypass urban areas soon began to weave their way across the country, forever altering the face of America.E)Long-span, segmented-concrete, cable-stayed bridges such as Hale Boggs inLouisiana and the Sunshine Skyway in Florida, and remarkable tunnels like Fort McHeny in Maryland and Mt. Baker in Washington, met many of the nation’s physical challenges. Traffic control systems and methods of construction developed under the interstate program soon influenced highway construction around the world, and were invaluable in improving the condition of urban streets and traffic patterns.F)Today, the interstate system links every major city in the U.S. with Canada andMexico. Built with safety in mind, the highways have wide lanes and shoulders, dividing medians, or barriers, long entry and exit lanes, curves engineered for safe turns, and limited access. The death rate on highways is half of all other U.S.roads (.86 deaths per 100 million passenger miles compared to 1.99 per 100 million on all other roads).G)By opening the North American continent, highways have enabled consumergoods and services to reach people in remote and rural areas of the country,spurred the growth of suburbs, and provided people with greater options in term of jobs, access to cultural programs, health care, and other benefits. Above all, the interstate system provides individuals with what they cherish most: personal freedom of mobility.H)The interstate system has been an essential element of the nation’s economicgrowth in terms of shipping and job creation: more than 75 percent the nation’s freight deliveries arrive by truck; and most products that arrive by rail or air use interstates for the last leg of the journey by vehicle. Not only has the highway system affected the America economy by providing shipping routes, it has led to the growth of spin-off industries like service stations, motels, restaurants, and shopping centers. It has allowed the relocation of manufacturing plants and other industries from urban areas to rural.I)By the end of the century there was an immense network of paved roads,residential streets, expressways, and freeways built to support millions of vehicles.The highway system was officially renamed for Eisenhower to honor his vision and leadership. The year construction began he said: “Together, the united forces of our communication and transportation systems are dynamic elements in the very name we bear—United States. Without them, we would be a mere alliance of many separate parts.”1.Many of the problems presented by the country’s geographical features foundsolutions in innovative engineering projects.2. A century ago, there were almost no national standards for paved roads in the U.S.3.The interstate system was renamed after Eisenhower in recognition of his visionand leadership.4.General Eisenhower felt that the broad motorways made more sense than thetwo-lane highways of America.5.It was in the 1950s that the American government finally took action to build anational highway system.6.Under safety considerations, the death rate on interstate highways is much lowerthan that of other American roads.7.Trucks using the interstate highways deliver more than seventy-five percent of thefreight in U.S.8.Thanks to the highways, American people can go anywhere they like around thecountry.9.To a certain extent, the development of interstate highway system in America haspromoted the nation’s economic growth.10.In terms of highway construction, the whole world was influenced by the U.S.(D B I B D F H G H E)Passage 4The MagicianThe revolution that Steve Jobs led is only just beginningA)When it came to putting on a show, nobody else in the computer industry, or anyother industry for that matter, could match Steve Jobs. His product launches, at which he would stand alone on a black stage and produce as if by magic an “incredible” new electronic gadget （小器具）in front of an amazed crowd, were the performances of a master showman. All computers do is fetch and work with numbers, he once explained, but do it fast enough and “the results appear to be magic”. Mr. Jobs, who died recently aged 56, spent his life packaging the magic into elegantly designed, easy-to-use products.B)The reaction to his death, with people leaving candles and flowers outside Applestores and politicians singing praises on the internet, is proof that Mr. Jobs had become something much more significant than just a clever money-maker. He stood out in three ways—as a technologist, as a corporate leader and as somebody who was able to make people love what had previously been impersonal, functional gadgets. Strangely, it is this last quality that may have the deepest effect on the way people live. The era of personal technology is in many ways just beginning.C)As a technologist, Mr. Jobs was different because he was not an engineer—andthat was his great strength. Instead he was keenly interested in product design and aesthetics（美学）, and in making advanced technology simple to use. He repeatedly took an existing but half-formed idea—the mouse-driven computer, the digital music player, the smartphone, the tablet computer（平板电脑）—and showed the rest of the industry how to do it properly. Rival firms competed with each other to follow where he led. In the process he brought about great changes in computing, music, telecoms and the news business that were painful for existing firms but welcomed by millions of consumers.D)Within the wider business world, a man who liked to see himself as a hippy,permanently in revolt against big companies, ended up being hailed by many of those corporate giants as one of the greatest chief executives of his time. That was partly due to his talents: showmanship, strategic vision, an astonishing attention to detail and a dictatorial management style which many bosses must have envied.But most of all it was the extraordinary trajectory（轨迹）of his life. His fall from grace in the 1980s, followed by his return to Apple in 1996 after a period in the wilderness, is an inspiration to any businessperson whose career has taken a turn for the worse. The way in which Mr. Jobs revived the failing company he had co-founded and turned it into the world’s biggest tech firm (bigger even than Bill Gate’s Microsoft, the company that had outsmarted Apple so dramatically in the 1980s), sounds like something from a Hollywood movie.E)But what was perhaps most astonishing about Mr. Jobs was the absolute loyalty hemanaged to inspire in customers. Many Apple users feel themselves to be part of a community, with Mr. Jobs as its leader. And there was indeed a personal link.Apple’s products were designed to accord with the boss’s taste and to meet his extremely high standards. Every iPhone or MacBook has his fingerprints all over it. His great achievement was to combine an emotional spark with computer technology, and make the resulting product feel personal. And that is what put Mr.Jobs on the right side of history, as technological innovation has moved into consumer electronics over the past decade.F)As our special report in this issue (printed before Mr. Job s’s death) explains,innovation used to spill over from military and corporate laboratories to the consumer market, but lately this process has gone into reverse. Many people’s homes now have more powerful, and more flexible, devices than their offices do;consumer gadgets and online services are smarter and easier to use than most companies’ systems. Familiar consumer products are being adopted by businesses, government and the armed forces. Companies are employing in-house versions of Facebook and creating their own “app stores” to deliver software to employees.Doctors use tablet computers for their work in hospitals. Meanwhile, the number of consumers hungry for such gadgets continues to swell. Apple’s products are now being snapped up in Delhi and Dalian just as in Dublin and Dallas.G)Mr. Jobs had a reputation as a control freak（怪人）, and his critics complained thatthe products and systems he designed were closed and inflexible, in the name of greater ease of use. Yet he also empowered millions of people by giving them access to cutting-edge technology. His insistence on putting users first, and focusing on elegance and simplicity, has become deep-rooted in his own company, and is spreading to rival firms too. It is no longer just at Apple that designers ask: “What would Steve Jobs do?”H)The gap between Apple and other tech firms is only likely to narrow. This week’sannouncement of a new iPhone by a management team led by Tim Cook, who replaced Mr. Jobs as chief executive in August, was generally regarded as competent but uninspiring. Without Mr. Jobs to shower his star dust on the event, it felt like just another product launch from just another technology firm. At the recent unveiling of a tablet computer by Jeff Bezos of Amazon, whose company is doing the best job of following Apple’s lead in combining hardware, software, content and services in an easy-to-use bundle, there were several attacks at Apple.But by doing his best to imitate Mr. Jobs, Mr. Bezos also flattered him. With Mr.Jobs gone, Apple is just one of many technology firms trying to arouse his uncontrollable spirit in new products.I)Mr. Jobs was said by an engineer in the early years of Apple to emit a “realitydistortion（扭曲）field”, such were his powers of persuasion. But in the end he created a reality of his own, channeling the magic of computing into products that reshaped entire industries. The man who said in his youth that he wanted to “put a ding in the universe” did just that.1.Steve Jobs was obsessed with elegant and user-friendly gadgets, which was hisgreat strength.2.In spite of the user-friendliness of Apple products, critics complained that theywere closed and inflexible.3.Steve Jobs fulfilled his promise and had succeeded in redefining the products incomputer industries.4.Steve Jobs started the era of personal technology, which has a profound impact onpeople’s way of life.5.Steve Jobs was thought highly of by leaders of many large companies for hisachievements and personal charm.6.Integrating the easy-to-use elements to the utmost, Amazon has become the bestApple follower many technology firms.7.Apple’s products are very popular in many industries and places, bringing muchcomfort and convenience to people’s life and work.8.No one can be compared with Steve Jobs in showmanship in the computerindustry or any other related industries.9.Having so many faithful users was the most amazing part of Steve Job s’ success.10.For those who have suffered failures in business, Steve Jobs’life experienceserves as an inspiration.(C G I B D H F A E D)Passage 5Should Sugar Be Regulated like Alcohol and Tobacco?A)Sugar poses enough health risks that it should be considered a controlledsubstance just like alcohol and tobacco, argue a team of researchers from the University of California, San Francisco (UCSF). In an opinion piece called “The Toxic Truth About Sugar”published Feb. 1 in Nature, Robert Lustig, Laura Schmidt and Claire Brindis argue that it’s wrong to consider sugar just “empty calories.”They write: “There is nothing empty about these calories. A growing body of scientific evidence is showing that fructose（果糖）can trigger processes that lead to liver toxicity and a host of other chronic diseases. A little is not a problem, but a lot kills—slowly.”B)Almost everyone’s heard of—or personally experienced—the well-known sugarhigh, so perhaps the comparison between sugar and alcohol or tobacco shouldn’t come as a surprise. But it’s doubtful that Americans will look favorably upon regulating their favorite vice. We’re a nation that’s sweet on sugar: the average U.S. adult downs 22 teaspoons of sugar a day, according to the American Heart Association, and surveys have found that teens swallow 34 teaspoons.C)To counter our consumption, the authors advocate taxing sugary foods andcontrolling sales to kids under 17. Already, 17% of U.S. children and teens are obese（肥胖的）, and across the world the sugar intake has increased three times in the past 50 years. The increase has helped create a global obesity plague that contributes to 35 million annual deaths worldwide from noninfectious diseases including cancer, heart disease and diabetes. Linda Matzigkeit, a senior vice president at Children’s Healthcare, said “We have to do something about this or our country is in danger. It’s not good if your state has the second-highest obesity rate. Obese children turn into obese adults.”D)“There are good calories and bad calories, just as there are good fats and bad fats,good amino acids（氨基酸）and bad amino acids,” Lustig, director of the Weight Assessment for Teen and Child Health program at UCSF, said in a statement. “But。

英语四级长篇阅读段落信息匹配题练习及答案-4

Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter.长篇阅读Definitions of ObesityA) How does one define when a person is considered to be obese and not just somewhat overweight? Height-weight tables give an approximate guideline as to whether one is simply overweight or has passed into the obese stage.B) The World Health Organization recommends using a formula that takes into account a person's height and weight. The "Body Mass Index" (BMI) is calculated by dividing the person's weight in kilograms by the square of their height in meters, and is thus given in units of kg/m2. A BMI of 18.5-24.9 is considered to be the healthiest. A BMI of between 25 and 29.9 is considered to be overweight, while a BMI of over 30 is considered to be obese.C) However, it is recognized that this definition is limited as it does not take into account such variables as age, gender and ethnic origin, the latter being important as different ethnic groups have very different fat distributions. Another shortcoming is that it is not applicable to certain very muscular people such as athletes and bodybuilders, who can also have artificially high BMIs. Agencies such as the National Cholesterol Education Program (NCEP) in the USA and the International Diabetes Foundation (IDF) are starting to define obesity in adults simply in terms of waist circumference.Health Effects of ObesityD) Over 2000 years ago, the Greek physician Hippocrates wrote that "persons who are naturally very fat are apt to die earlier than those who are slender". This observation remains very true today. Obesity has a major impact on a person's physical, social and emotional well-being. It increases the risk of developing diabetes mellitus type 2 ("mature onset diabetes") and also makes Type 2 diabetes more difficult to control. Thus weight loss improves the levels of blood glucose and blood fats, and reduces blood pressure. The association between obesity and coronary heart disease is also well-known.CancerE) Furthermore, in 2001 medical researchers established a link between being overweight and certain forms of cancer, and estimated that nearly 10,000 Britons per year develop cancer as a result of being overweight. This figure was made up of 5,893 women and 3,220 men, with the strongest associations being with breast and colon cancers. However, it is thought that being overweight may also increase the risk of cancer in the reproductive organs for women and in the prostate gland for men.F) The link between breast cancer and nutritional status is thought to be due to the steroid hormones oestrogen and progesterone, which are produced by the ovaries, and govern a woman's menstrual cycle. Researchers have found that the more a woman eats, or the more sedentary her lifestyle, the higher are the concentrations of progesterone. This link could explain why women from less affluent countries have lower rates of breast cancer. Women from less affluent nations tend to eat less food and to lead lifestyles which involve more daily movement. This lowers their progesterone level, resulting inlower predisposition to breast cancer.G) The Times newspaper, in 2002 reported that obesity was the main avoidable cause of cancer among non-smokers in the Western world!AgingH) Research published by St Thomas' Hospital, London, UK in 2005 showed a correlation between body fat and aging, to the extent that being obese added 8.8 years to a woman's biological age. The effect was exacerbated by smoking, and a non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to their biological age. The combination of being obese and asmoker added at least ten years to a woman’s biological age, and although the study only involved women, the lead researcher Professor Tim Spector believes the finding would also apply to men.I) The aging effect was determined by measuring the length of telomeres, tiny "caps" on the ends of chromosomes, which help protect the DNA from the ageing process. Indeed, telomeres have been dubbed the "chromosomal clock" because, as an organism ages, they become progressively shorter, and can be used to determine the age of the organism. Beyond a certain point, the telomere becomes so short that it is no longer able to prevent the DNA of the chromosome from falling apart. It is believed that excess body fat, and the chemicals present in tobacco smoke release free radicals which trigger inflammation. Inflammation causes the production of white blood cells which increases the rate of erosion of telomeres.DementiaJ) Recent research (2005) conducted in the USA shows that obesity in middle age is linked to an increased risk of dementia, with obese people in their 40s being 74% more likely to develop dementia compared to those of normal weight. For those who are merely overweight, the lifetime risk of dementia risk was 35% higher.K) Scientists from the Aging Research Centre at the Karolinska Institute in Sweden have been able to take information such as age, number of years in education, gender, body mass index, blood pressure level, physical activity and genetic factors, assigning each a risk score. They then used this information to devise a predictive test for dementia. This test will enable people at risk, for the first time, to be able to affect lifestyle changes which will reduce their risk of contracting dementia.Other ProblemsL) The world-wide upsurge in obesity, particularly in children, is of major economic concern, liable to drain economies. Of further concern is that research conducted in Australia and published in 2006, shows that up to one third of breech pregnancies were undetected by the traditional "palpation" examination, the danger being greatest for those women who are overweight or obese—a growing proportion of mothers. This means that such women are not getting thetreatment required to turn the baby around in time for the birth, and in many cases require an emergency Caesarean section.M) This is a true health-care crisis, far bigger than Severe Acute Respiratory Syndrome (SARS) and ultimately, even bigger than AIDS.对应题目：1. You can judge whether one is simply overweight or has passed into the obese stage according to the height-weight table.2.

大学英语四级信息匹配练习题

⼤学英语四级信息匹配练习题⼤学英语四级信息匹配练习题⼀Directions: In this section, you are going to read a passage withten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter.长篇阅读Preparing for Computer DisastersA) Summary: When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward.B) Fires, power surges, and floods, they're all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate over their bad luck. We also shake our heads at the digital consequences—melted computers, system failures, destroyed data.Yet, somehow, many of us continue to live by that old mantra of denial: "It won't happen to me." Well, the truth is, at some pointyou'll probably have to deal with at least one disaster. That's just how it goes, and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disaster plans and run drills. But for some reason, computer disaster recovery is a blind spot for many of us. It shouldn't be. Home computers contain some of our most important information, both business and personal, and making certain our data survives a disaster should be a priority. Moreover, even the smallest disaster can be a serious disruption. Personal computers have become an integral part of the smooth-running household. We use them to communicate, shop, and do homework, and they're even more vital to home office users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. With a good offsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a major calamity strike, you can rest assured your data is safe.Offsite Storage: Major DisastersC) House fires and floods are among the most devastating causes of personal computer destruction. That's why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their house flood our burn. That's because they keep their backups inrelatively close to their computers. Their backup disks might not be in the same room as their computers—tucked away in a closet or even the garage—but they're not nearly far enough away should a seriousdisaster strike. So, it's important to back up your system to a removable medium and to store it elsewhere.D) There are many ways to approach offsite storage. It starts with choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldn't add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in apinch. They must also be compatible with your choice of backup medium. Depending on your tools, you can back up to a variety of durable disk types—from CDs to Jaz drives to remote network servers. Although many of these storage media have high capacity, a backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.E) Once you select your tools and a suitable medium, you need tofind a remote place to store your backups. The options are endless. However, no matter where you choose, be sure the site is secure, easily accessible, and a good distance away from your home. You may also want to consider using an Internet-based backup service. More and more service providers are offering storage space on their servers, and uploading files to a remote location has become an attractivealternative to conventional offsite storage. Of course, before using one of these services, make certain you completely trust the service provider and its security methods. Whatever you do, schedule backups regularly and store them far away fromyour home.Come What May: Handling the Garden Variety Computer CrisisF) Not all home computer damage results from physical disaster. Many less menacing problems can also hobble your PC or destroy your information. Systems crash, kids "rearrange" data, adults inadvertently delete files. Although these events might not seem calamitous, they can have serious implications. So, once again, it's important to be prepared. As with physical disasters, regular backups are essential. However, some of these smaller issues require a response that's more nuanced than wholesale backup and restoration. To deal with less-than-total disaster, your tool set must be both powerful and agile. For example, when a small number of files are compromised, you may want to retrieve those files alone. Meanwhile, if just your settings are affected, you'll want a simple way to roll back to your preferred setup. Yet, should your operating system fail, you'll need a way to boot your computer and perform large-scale recovery. Computer crises come in all shapes and sizes, and your backup and recovery tools must be flexible enough to meet each challenge.The Right Tools for the Right Job: Gearing up for DisasterG) When disaster strikes, the quality of your backup tools can make the difference between utter frustration and peace of mind. Symantec understands this and offers a range of top quality backup and recovery solutions. Norton GoBack is the perfect tool for random system crashes, failed installations, and inadvertent deletions. With this powerful and convenient solution, it's simple to retrieve overwritten files or to bring your system back to its pre-crash state. Norton Ghost is a time-tested home office solution. Equipped to handle full-scale backups, it's also handy for cloning hard drives and facilitating system upgrades. A favorite choice for IT professionals, it's the ideal tool for the burgeoning home office. You can buy Norton Ghost and Norton GoBack separately, or get them both when you purchase Norton System Works.H) Life's disasters, large and small, often catch us by surprise. However, with a little planning and the right tools, you can reduce those disasters to bumpsin the road. So, don't wait another day. Buy a good set of disaster recovery tools, set up an automatic backup schedule, and perform a dry run every now and again. Then, rest easy.对应题⽬:1. You should take steps to recover from computer disasters so as to minimize their effects.2. For some reason, computer disaster recovery is always ignored by many of us.3. You can bounce back quickly and easily minor computer disasters with the help of a good offsite storage plan and the right tools.4. The most devastating causes of personal computer destruction includes house fires and floods.5. It's necessary for us to back up our systems to some transferable medium and to put it somewhere else.6. You should find a distant place to store your backups after selecting your tools and a suitable medium.7. Not only physical disaster can damage your computer.8. The backup and recovery tools must be flexible enough to deal with various computer crises.9. The quality of your backup tools determines whether you are frustrated or have a peaceful mind when disaster strikes.10. You should prepare for your computer disasters now and again.答案参考:1.

How to Make Attractive and Effective PowerPoint PresentationsA) Microsoft PowerPoint has dramatically changed the way in which academic and business presentations are made. This article outlines few tips on making more effective and attractive PowerPoint presentations.The TextB) Keep the wording clear and simple. Use active, visual language. Cut unnecessary words—a good rule of thumb is to cut paragraphs down to sentences, sentences into phrases, and phrases into key words. Limit the number of words and lines per slide. Try the Rule of Five-five words per line, five lines per slide. If too much text appears on one slide, use the AutoFit feature to split it between two slides. Click within the placeholder to display the AutoFit Options button (its symbol is two horizontal lines with arrows above and below), then click on the button and choose Split Text between Two Slides from the submenu.C) Font size for titles should be at least 36 to 40, while the text body should not be smaller than 24. Use only two font styles per slide—one for the title and the other for the text. Choose two fonts that visually contrast with each other. Garamond Medium Condensed and Impact are good for titles, while Garamond or Tempus Sans can be used for the text body.D) Embed the fonts in your presentation, if you are not sure whether the fonts used in the presentation are present in the computer that will be used for the presentation. To embed the fonts: (1) On the File menu, click Save As. (2) On the toolbar, click Tools, click Save Options, select the Embed TrueType Fonts check box, and then select Embed characters in use only.E) Use colors sparingly; two to three at most. You may use one color for all the titles and another for the text body. Be consistent from slide to slide. Choose a font color that contrasts well with the background.F) Capitalizing the first letter of each word is good for the title of slides and suggests a more formal situation than having just the first letter of the first word capitalized. In bullet point lines, capitalize the first word and no other words unless they normally appear capped. Upper and lower case lettering is more readable than all capital letters. Moreover, current styles indicate that using all capital letters means you are shouting. If you have text that is in the wrong case, select the text, and then click Shift+F3 until it changes to the case style that you like. Clicking Shift+F3 toggles the text case between ALL CAPS, lower case, and Initial Capital styles.G) Use bold or italic typeface for emphasis. Avoid underlining, it clutters up the presentation.Don’t center bulleted lists or text. It is confusing to read. Left align unless you have a good reason not to. Run “spell check”on your show when finished.The BackgroundH) Keep the background consistent. Simple, light textured backgrounds work well. Complicated textures make the content hard to read. If you are planning to use many clips in your slides, select a white background. If the venue of your presentation is not adequately light-proof, select adark-colored background and use any light color for text. Minimize the use of “bells and whistles”such as sound eff ects, “flying words” and multiple transitions. Don’t use red in any fonts or backgrounds. It is an emotionally overwhelming color that is difficult to see and read.The ClipsI) Animations are best used subtly; too much flashand motion can distract and annoy viewers. Do not rely tooheavily on those images that were originally loaded on your computer with the rest of Office. You can easily find appropriate clips on any topic through Google Images. While searching for images, do not use long search phrases as is usually done while searching the web-use specific words.J) When importing pictures, make sure that they are smaller than two megabytes and are in a .jpg format. Larger files can slow down your show. Keep graphs, charts and diagrams simple, if possible. Use bar graphs and pie charts instead of tables of data. The audience can then immediately pick up the relationships.The PresentationK) If you want your presentation to directly open in the slide show view, save it as a slide show file using the following steps. Open the presentation you want to save as a slide show. On the File menu, click Save As. In the Save as type list, click PowerPoint Show. Your slide show file will be saved with a ppt file extension. When you double-click on this file, it will automatically start your presentation in slide show view. When you’re done, PowerPoint automatically closes and you return to the desktop. If you want to edit the slide show file, you can always open it from PowerPoint by clicking Open on the File menu.L) Look at the audience, not at the slides, whenever possible. If using a laser pointer, don’t move it too fast. For example, if circling a number on the slide, do it slowly. Never point the las er at the audience. Black out the screen (use “B”on the keyboard) after the point has been made, to put the focus on you. Press the key again to continue your presentation.M) You can use the shortcut command [Ctrl]P to access the Pen tool during a slide show. Click with your mouse and drag to use the Pen tool to draw during your slide show.To erase everything you’ve drawn, press the E key. To turn off the Pen tool, press [Esc] once.MiscellaneousN) Master Slide Set-Up: The “master slide”will allow you to make changes that are reflected on every slide in your presentation. You can change fonts, colors, backgrounds, headers, and footers at the “master slide”level. First, go to the “View” menu. Pull down the “Master”menu. Select the “slide master”menu. You may now make changes at this level that meet your presentation needs.对应题目：1. The ways in which academic and business presentations are made have been changed by Microsoft PowerPoint.2. When making the PowerPoint, the wording of the text should not be complicated.3. In each slide, the font styles for the title and the text should contrast with each other.4. A more formal situation is capitalizing the first letter of the first word.5. Centering bulleted lists or text can not help to read.6. Sound effects should be used as less frequently as possible.7. When importing pictures, make sure that they are smaller than two megabytes.8. When making the presentation, you should look at the audience as possible as you can.9. Pressing the E key can help you to erase everything you've drawn.10. In order to meet your presentation needs, you can make changes at the “slide master”level.答案参考：1.
