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. Answer the questions by marking the corresponding letter on Answer Sheet 2.Countries Rush for Upper Hand in AntarcticaA) On a glacier-filled island with fjords(峡湾)and elephant seals, Russia has built Antarcticas first Orthodox church on a bill overlooking its research base. Less than an hour away by snowmobile. Chinese laborers have updated the Great Wall Station, a vital part of Chinas plan to operate five basses on Antarctica, complete with an indoor badminton court and sleeping quarters for 150 people. Not to be outdone, Indias futuristic new Bharathi base, built on stills(桩子)using 134 interlocking shipping containers, resembles a spaceship. Turkey and Iran have announced plans to build bases, too.B) More than a century has passed since explorers raced toplant their flags at the bottom of the world, and for decades to come this continent is supposed to be protected as a scientific preserve, shielded from intrusions like military activities and mining . But an array of countries are rushing to assert greater influence here, with an eye not just towards the day those protective treaties expire, but also for the strategic and commercial that already exist.C) The newer players are stepping into what they view as a treasure house of resources. Some of the ventures focus on the Antarctic resources that are already up for grabs, like abundant sea life. South Korea, which operates state-ofthe-art bases here, is increasing its fishing of krill(磷虾)，found in abundance in the Southern Ocean, while Russia recently frustrated efforts to create one of the worlds largest ocean sanctuaries here.D) Some scientists are examining the potential for harvesting icebergs form Antarctica, which is estimated to have the biggest reserves of fresh water on the planet. Nations are also pressing ahead with space research and satellite projects to expand their global navigation abilities.E) Building on a Soviet-era foothold, Russia is expanding its monitoring stations for Glonass, its version of the Global Positioning System(GPS). At least three Russian stations are already operating in Antarctica, part of its effort to challenge the dominance of the American GPS, and new stations are planned for sites like the Russian base, in the shadow of the Orthodox Church of the Holy Trinity.F) Elsewhere in Antarctica, Russian researchers boast of their recent discovery of a freshwater reserve the size of Lake Ontario after drilling through miles o f solid ice. “You can see that were here to stay,” said Vladimir Cheberdak, 57, chief of the Bellingshausen Station, as he sipped tea under a portrait of Fabian Gottlieb von Bellingshausen, a high-ranking officer in the Imperial Russian Navy who explored the Antarctic coast in 1820.G) Antarcticas mineral, oil and gas wealth are alonger-term prize. The treaty banning mining here, shielding coveted(令人垂诞的)reserves of iron ore, coal and chromium, comes up for review in 2048. Researchers recently found kimberlite(金伯利岩) deposits hinting at the existence of diamonds. And while assessments vary widely, geologists estimate that Antarctica holds at least 36 billion barrels of oil and natural gas.H) Beyond the Antarctic treaties, huge obstacles persist to tapping these resources, like drifting icebergs that could jeopardize offshore platforms. Then there is Antarctics remoteness, with some mineral deposits found in windswept locations on a continent that is larger the Europe and where winter temperatures hover around minus 55 degrees Celsius.I) But advances in technology might make Antarctica a lot more accessible three decades from now. And even before then, scholars warn, the demand for resources in an energy-hungry world could raise pressure to renegotiate Antarcticas treaties, possibly allowing more commercial endeavours here well before the prohibitions against them expire. The research stations onKing George lsland offer a glimpse into the long game on this ice-blanketed continent as nations assert themselves, eroding the sway long held by countries like the United States, Britain. Australia and New Zealand.J) Being stationed in Antarctica involves adapting to life on the planets driest, windiest and coldest continent, yet each nation manages to make itself at home. Bearded Russian priests offer regular services at the Orthodox church for the 16 or so Russian speakers who spend the winter at the base, largely polar scientists in fields like glaciology and meteorology. Their number climbs to about 40 in the warmer summer months. China has arguably the fastest growing operations in Antarctica. It opened its fourth station last year and is pressing ahead with plans to build a fifth. It is building its second ice-breaking ship and setting up research drilling operations on an ice dome 13,422 feet above sea level that is one the planets coldest places. Chinese officials say the expansion in Antarctica prioritises scientific research. But they also acknowledge that concerns about “resource security” influence their moves.K) Chinas newly renovated Great Wall Station on King George lsland makes the Russian and Chilean bases here seem outdated. ”We do weather monitoring here and other research.” Ning Xu, 53, the chief of the Chinese base, said over tea during a fierce blizzard(暴风雪) in late November. The large base he leads resembles a snowed-in college campus on holiday break, with the capacity to sleep more than 10 times the 13 people who were staying on through the Antarctic winter. Yong Yu, a Chinese microbiologist, showed off the spacious building, with emptydesks under an illustrated timeline detailing the rapid growth of Chinas Antarctic operations since the 1980s “We now feel equipped to grow,” he said.L) As some countries expand operations in Antarctica, the United States maintains three year-round stations on the continent with more than 1,000 people during the southern hemispheres summer, including those at the Amundsen Scott station, built in 1956 at an elevation of 9,301 feet on a plateau at the South Pole. But US researchers quietly complain about budget restraints and having far fewer icebreakers the Russia, limiting the reach of the United States in Antarctica.M) Scholars warn that Antarcticas political drift could blur the distinction between military and civilian activities long before the continents treaties come up for renegotiation, especially in parts of Antarctica that are ideal for intercepting(拦截) signals from satellites or retasking satellite systems, potentially enhancing global electronic intelligence operations.N) Some countries have had a hard time here, Brazil opened a research station in 1984, but it was largely destroyed by a fire that killed two members of the navy in 2023, the same year that a diesel-laden Brazilian barge sank near the base. As if that were not enough. a Brazilian C-130 Hercules military transport plane has remained stranded near the runway of Chiles air base here since it crash-landed in 2023.O) However, Brazils stretch of misfortune has created opportunities for China, with a Chinese company winning the$100 million contract in 2023 to rebuild the Brazilian station.P) Amid all the changes, Antarctica maintains its allure. South Korea opened its second Antarctic research base in 2023, describing it as a way to test robots developed by Korean researchers for use in extreme conditions. With Russias help, Belarus is preparing to build this first Antarctic base. Colombia said this year that it planned to join other South American nations with bases in Antarctica.Q) “The old days of the Antarctic being dominated by the interests and wishes of white men from European. Australasian and North American states are over.” Said Klaus Dodds, a politics scholar at the University of London who specialises in Antarctica. “The reality is that Antarctica is geopolitically contested.”36. According to Chinese officials, their activities in Antarctica lay greater emphasis on scientific research.37. Efforts to create one of the worlds largest ocean sanctuaries failed because of Russias obstruction.38. With several monitoring stations operating in Antarctica, Russia is trying hard to counter Americas dominance in the field of worldwide navigational facilities.39. According to geologists estimates. Antarctica has enormous reserves of oil and natural gas.40. It is estimated that Antarctica boasts of the richestreserves of fresh water on earth.41. The demand for energy resources may compel renegotiation of Antarcticas treaties before their expiration.42. Many countries are racing against each other to increase their business and strategic influence on Antarctica.43. Antarcticas harsh natural conditions constitute huge obstacles to the exploitation of its resources.44. With competition from many countries, Antarctica is no longer dominated by the traditional white nations.45. American scientists complain about lack of sufficient money and equipment for their expansion in Antarctica.参考答案Section BCountries Rush for Upper Hand in Antarctica36. [J]37. [C]38. [E]39. [G]40.

六级考试段落匹配训练题***一***Defitions 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 orhas passed into the obese stage.B: The World Health Orgazation remends 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 inkilograms by the suare of their height in meters, and is thus given in uts 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 beoverweight, while a BMI of over 30 is considered to be obese.C: However, it is recogzed that this defition is limited as it does not take into account such variables as age, gender and ethc origin, the latter being imrtant as different ethcgroups he very different fat distributions. Another shorting is that it is not applicable to certain very muscular people such as athletes and bodybuilders, XX can also he artificiallyhigh BMIs.Agencies such as the National Cholesterol Education Program ***NCEP*** in the USA and the International Diabetes Foundation ***IDF*** are starting to define obesity inadults simply in termsof waist circumference.Health Effects of ObesityD: Over 2000 years ago, the Greek physician Hipcrates wrote that "persons XX are naturally very fat are apt to die earlier than those XX are slender". This observation remains very truetoday. Obesity has a major impact on a person's physical, social and etional well-being. It increases the risk of developing diabetes mellXXs type 2 ***"mature onset diabetes"*** and also makesType 2 diabetes re difficult to control. Thus weight loss improves the levels of blood glucose and blood fats, and reduces blood pressure. The association between obesity andcoronary heartdisease is also well-known.CancerE: Furtherre, in 2021 medical researchers established a link betweenbeing overweight and certain forms of cancer, and estimated that nearly 10,000 Britons per year develop cancer asaresult of being overweight. This figure was made up of5,893 women and 3,220 men, with the strongest associations being with breast and colon cancers. However, it is thought that beingoverweight may also increase the risk of cancerin 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 hornes oestrogen and progesterone, which are produced by the ovaries, and govern a woman'enstrual cycle. Researchers he found that the re a woman eats, or the re sedentary her lifestyle, the higher are the concentrations of progesterone. This link could explain why womenfrom less affluent countries he lower rates of breast cancer. Women from less affluent nations tend to eat less food and to lead lifestyles which involve re daily vement. This lowerstheir progesterone level, resulting in lower predissition to breast cancer.G: The Times newspaper, in 2021 rerted that obesity was the main oidable cause of cancer ang non-okers in the Western world!AgingH: Research published by St Thomas' Hospital, London, UK in 2021 showed a correlation between body fat and aging, to the extentthat being obese added 8.8 years to a woman's biological age.The effect was exacerbated by oking, and a non-overweight woman XX okes 20 cigarettes a day for 20 years added 7.4 years to their biological age. The bination of being obese and aoker added at least ten years to awoman’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 chrosomes, which help protect the DNA from the ageing process. Indeed, telomeres hebeen dubbed the "chrosomal clock" bXXuse, as an orga ages, they bee progressively shorter, and can be used to determine the age of the orga. Beyond a certain int, the telomerebees so short that it is no longer able to prevent the DNA of the chrosome from falling apart. It is believed that excess body fat, and the chemicals present in tobacco oke release freeradicals which trigger inflammation. Inflammation causes the production of white blood cells which increases the rate of erosion of telomeres.DementiaJ: RXXnt research ***2021*** 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% re likely to developdementia pared to those of normal weight. For those XX are merely overweight, the lifetime risk of dementiarisk was 35% higher.K: Scientists from the Aging Research XX at the Karolinska InstXXte in Sweden he been able totake information such as age, number of years in education, gender, body mass index, bloodpressure level, physical activity and genetic factors, assigng each a risk score. They then used this information to devise a predictive test for dementia. This test will enable people atrisk, for the first time, to be able to affect lifestyle nges 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 andpublished in 2021, shows that up to one third of breech pregnancies were undetected by the traditional "palpation" examination, the danger being greatest for those women XX are overweight orobese—a growing prortion of thers. This means that such women are not getting the treatment reuired to turn the baby around in time for the birth, and in many cases reuire an emergencyCaesarean section.M: This is atrue health-care crisis, far bigger than Severe Acute Respiratory Syndrome ***SARS*** and ultimately, even bigger than AIDS.1. You can judge whether one is simply overweight or has passed into the obese stage according to the height-weight table.2. Using the "Body Mass Index"to define aperson's weight ideal is limited, bXXuse it does not takes into account many variables such as age, gender and ethc origin.3. A person's etional well-being would be affected by obesity.4. Obesity has something to do with cancer in the prostate gland for man.5. Women from less affluent nations tend to he much less breast cancer.6. A non-overweight woman XX okes 20 cigarettes a day for 20 years added 7.4 years to her biological age.7. The excess body fat, like the chemicals present in tobacco oke, can lead to inflammation.8. Obese people in middle age run an increased risk of dementia .9. The predictive test for dementia will help people to affect lifestyle nges that will reduce their risk of contracting dementia.10. The world-wide upsurge in obesity, particularly in children, will ssibly drain economies.六级考试段落匹配训练题答案1. A2. C3. D4. E5. F6. H7. I8. J9. K10. L英语六级考试中，长段落匹配题篇章长，对考生的整体阅读能力有了更高的要求，需要考生重视平时的阅读训练。

英语六级阅读段落匹配训练

英语六级阅读段落匹配训练In the modern era where English has become the global language, it is crucial for individuals to possess strong English language skills. The English Proficiency Test, also known as the English Six Level (CET-6), is an important benchmark for assessing English language proficiency for non-English major students in China. To excel in the CET-6 reading section, it is essential to practice and improve your ability to match paragraphs effectively. In this article, we will explore the strategies and techniques required to succeed in the CET-6 reading paragraph matching exercises.1. Understand the TaskBefore delving into the techniques, it is crucial to understand the requirements of the task. In the CET-6 reading section, you will be presented with several paragraphs and a list of headings. Your task is to match the paragraphs with the most appropriate headings. This exercise tests your ability to comprehend the main idea of each paragraph and identify the most suitable heading.2. Skim and ScanSkimming and scanning are vital techniques when it comes to paragraph matching. Skimming allows you to quickly read through the paragraphs to get a general idea of their content. Take note of any keywords or phrases that stand out. Scanning, on the other hand, involves searching for specific information within the paragraphs. Skimming and scanning techniques help you narrow down the options and match the correct paragraph with the heading.3. Identify Central IdeasEach paragraph will have a central idea or main topic. Understanding the main idea of a paragraph is crucial for successful paragraph matching. Read the first and last sentence of each paragraph to grasp the overall concept. Look for keywords, repeated phrases, or any other clues that hint at the paragraph's central idea. By identifying the central idea, you can better match the paragraph with the appropriate heading.4. Pay Attention to Transition WordsTransition words play a significant role in connecting ideas within a text. Watch out for transition words such as "however," "in contrast," "similarly," or "on the other hand." These words provide important context and help establish the relationship between sentences and paragraphs. Recognizing these transition words can guide you in matching the paragraphs with the correct headings.5. Practice with Sample QuestionsTo improve your paragraph matching skills, practice with sample questions from previous CET-6 exams. Familiarize yourself with the types of headings and the style of writing used in the test. Set aside dedicated study time to answer these questions, and review your answers carefully. Understanding the patterns and common themes in CET-6 paragraph matching exercises will enhance your performance on the actual test.In conclusion, excelling in the CET-6 reading section requires practice and skill in matching paragraphs. By understanding the task, employing skimming and scanning, identifying central ideas, paying attention totransition words, and practicing with sample questions, you can enhance your ability to match paragraphs accurately. Remember to remain focused and attentive while reading, and trust your instincts when making the final match. With dedication and persistence, you can improve your performance in the CET-6 reading section and enhance your overall English language proficiency.。

练习题⼀ [A] One of the biggest surprises of President Barack Obama's inaugural address,on Monday was how much he focused on fighting climate change, spending more time on that issue than any other. "We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," Obama said. The President pointed out that recent severe weather supplied an urgent impetus for energy innovation and staked the nation's economic future on responding to a changing climate. "We cannot cede to other nations the technology that will power new jobs and new industries--we must claim its promise," Obama said. '" That's how we will maintain our economic vitality and our national treasure--our forests and waterways; our croplands and snowcapped (⼭顶积雪的) peaks. That is how we will preserve our planet, commanded to our care by God. " so what could the President reasonably do to deliver on that vow? Here are ten of their suggestions: Sunset coal with new incentives and regulations. [B] "Provide incentives to phase out the oldest, most polluting power plants," said Robert Jackson, a climate scientist at Duke University. It's already happening, to some degree, as more of the nation transitions to natural gas. Earth scientist Bill Chameides, dean of Duke's Nicholas School of the Environment and a former chief scientist at the Environmental Defense Fund, urges the administration to use its Clean, Air Act authority to promulgate (颁布 )carbon regulations for existing power plants like it has for new ones: "Doing that will force fuel switching from coal to natural gas. "Invest federal stimulus money in nuclear power. [C] It's hardly a perfect fuel, as accidents like Japan's Fukushima fallout have shown, but with safety precautions new nuclear plants can meaningfully offset dirtier types of energy, supporters say."Nuclear is the only short-to medium-term way to really get away from fossil fuels," said Peter Raven. President emeritus of the Missouri Botanical Garden. He said the damage done by relentless global warming will far exceed the damage done by faults in the nuclear system. Kill the Keystone pipeline. [D] The controversial Keystone XL oil pipeline is up for review again by the White House this year. "The font thing he should do to set the tone to a lower carbon economy is to reject the Keystone pipeline, “said Raymond Pierrehum Bert, a geophysical scientist at the University of Chicago. The pipeline was never going to be a major driver of global emissions, but Pierre humbert and some other environmentalists say that by killing it the President would send a clear message about America's intent to ramp down fossil fuels. Protect the oceans by executive order. [E] Land use is complicated, but large swaths of oceans can be protected by executive order. Just as President George W. Bush designated the world's largest marine monument northwest of Hawaii in 2006. Obama could single-handedly protect other areas. National Geographic Explorer-in-Residence Sylvia Earle said the President should focus on parts of the Arctic that are under U. S. control, putting them off limits to energy production, commercial fishing, and mineral exploration. Marine sanctuaries (禁捕区) won't stop climate change, but they can give marine species a better chance of adapting to it by reducing the other man-made threats the animals face. Experiment with capturing carbon. [F] Huge untapped reserves of natural gas and oil make it unlikely that the U. S. will transition away from fossil fuels inthe immediate future. Instead, said Wallace Broecker, geology professor at Columbia University's Lamont-Doherty Earth Observatory, we should attack the atmosphere's carbon surplus directly. "Obama could make available funds to build and test prototype air capture units" to capture and store CO2, said Broecker. Removing some carbon from the atmosphere could buy valuable time as policy makers and scientists explore more permanent solutions. Grow government research for new energy sources. [G] The Department of Energy has a nimble program that's tasked with innovative energy research—the Advanced Research Projects Agency-Energy. The ARPA-E funds research in biofuels, transmission,and battery storage, with an annual budget of $ 275 million. Last year, DOE officials requested at least $ 75 million more. Increasing funding for ARPA-E, said Rare Pomerance, former deputy assistant secretary of state for environment and development and currently an environmental consultant, "you get new technologies that undercut coal, oil, and gas. " Plus, he said, yon get a competitive advantage if American researchers uncover the next big idea in new energy.。

英语六级改革新题型长篇阅读练习（一）英语六级新题型练习之长篇阅读：段落匹配题。

Paper--More than Meets the EyeA） We are surrounded by so much paper and card that it is easy to fo rget just how complex it is. There are many varieties and grades of paper materials， and whilst it is fairly easy to spot the varieties， it is far more difficult to spot the grades.B） It needs to be understood that most paper and card is manufactur ed for a specific purpose， so that whilst the corn-flake packet may look s mart， it is clearly not something destined for the archives. It is made to l ook good， but only needs a limited life span. It is also much cheaper to manufacture than high grade card.C） Paper can be made from an almost endless variety of cellulose-based material which will include many woods， cottons and grasses or which pap yrus is an example and from where we get the word "paper". Many of the se are very specialized， but the preponderance of paper making has been from soft wood and cotton or rags， with the bulk being wood-based.Paper from WoodD） In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery and then boiled with strong alkalie s such as caustic soda， until a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made， relying on the bonding to gether of the cellulose into layers. That， in a very small nutshell， is the e ssence of paper making from wood. However， the reality is rather more c omplicated. In order to give us our white paper and card， the makers willadd bleach and other materials such as china clay and additional chemical s.E） A further problem with wood is that it contains a material that is not cellulose. Something called lignin. This is essential for the tree since it hol ds the cellulose fibres together， but if it is incorporated into the manufact ured paper it presents archivists with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look ra ther brown and careworn. We have all seen this in old newspapers and ch eap paperback books. It has been estimated that most paper back books will have a life of not greater than fifty years. Not what we need for our a rchives.F） Since the lignin can be removed from the paper pulp during manufact ure， the obvious question is "why is it left in the paper?" The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tr ee to some 95%. Removing it means a yield of only 35%. It is clearly un economic to remove the lignin for many paper and card applications.G） It also means， of course， that lignin-free paper is going to be more expensive， but that is nevertheless what the archivist must look for in hi s supplies. There is no point whatsoever in carefully placing our valuable a rtifacts in paper or card that is going to hasten their demise. Acid is partic ularly harmful to photographic materials， causing them to fade and is som e cases simply vanish！H） So， how do we tell a piece of suitable paper or card from one tha t is unsuitable? You cannot do it by simply looking， and rather disappointi ngly， you cannot always rely on the label. "Acid-free" might be true inasm uch as a test on the paper may indicate that it is a neutral material at thi s time. But lignin can take years before it starts the inevitable process of breaking down， and in the right conditions it will speed up enormously.I） Added to this， as I have indicated earlier， paper may also contain other materials added during manufacture such as bleach， china clay， che mical whiteners and size. This looks like a bleak picture， and it would be but for the fact that there are suppliers who will guarantee the material th at they sell. If you want to be absolutely sure that you are storing in， or printing on， the correct material then this is probably the only way.J） Incidentally， acids can migrate from material to material. Lining old shoe boxes with good quality acid-free paper will do little to guard the co ntents. The acid will get there in the end.Paper from RagK） Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free， but because there is much less cotton and rag than trees， it also tends to be much more expensive than wood p ulp paper. You will still need to purchase from a reliable source though， si nce even rag paper and card can contain undesirable additives.L） A reliable source for quality rag papers is a recognized art stockiest. Many water color artists insist on using only fine quality rag paper and b oard.M） The main lesson to learn from this information is that you cannot r ely on purchasing archival materials from the high street. The only safe so lution is to purchase from specialist suppliers. It may cost rather more， bu t in the end you will know that your important and valuable data and ima ges have the best home possible.1. The corn-flake packet is cheaper than high grade card.2. There are a lot of materials which can be used for making paper， b ut the superiority ones are soft wood， cotton and rags.3. During the whole manufacturing process， the final product is made from a pulp of cellulose fibres.4. In order to make white paper and card， the makers will add bleach.5. Liguin is essential for the tree but it will make paper easy to break.6. Many paper producers will preserve lignin during manufacture， beca use leaving the lignin will make more paper from a tree.7. Acid is particularly harmful to photographic materials.8. If the lignin is removed from the paper， the paper will be more exp ensive.9. Although free of lignin， paper made from cotton and rag waste can also cost more money than wood pulp paper because there is much less c otton and rag than trees.10. What we can learn from "Paper from Rag" is that you had better b uy archival materials from specialist suppliers.文章精要本文主要介绍了我们平常所见所用的纸的复杂性，通过介绍用木头和破布料造纸的过程，使我们对纸的类别、属性有了更深入的了解。

英语六级阅读段落匹配题模拟

英语六级阅读段落匹配题模拟In the bustling city, the sun sets gracefully, casting a warm glow on the bustling streets. The city's heartbeat quickens as the evening commute begins, a symphony of wheels and engines.A young student, immersed in her book, sits on a park bench, oblivious to the world around her. Her eyes flicker with the light of understanding as she navigates the complexities of the text, a testament to her dedication.At the heart of the city, a café buzzes with life. Patrons exchange stories and laughter over steaming cups of coffee, creating a tapestry of human connection in the urban jungle.Meanwhile, in a quiet corner, an elderly man pens a letter, his hand steady and his words thoughtful. The ink flows like a river of memories, capturing a lifetime of experiences.Across town, a group of friends gather around a table, their faces lit by the soft glow of a lamp. They sharestories of their day, each anecdote a thread in the fabric of their friendship.In the tranquility of a library, the silence is broken only by the rustle of pages turning. Here, knowledge iswhispered in the hushed tones of the curious and the eager.As night falls, the city lights up like a constellation of dreams and aspirations. The glow of windows and street lamps illuminates the path of those who continue to chase their goals, undeterred by the darkness.In the stillness of the night, a mother reads a bedtime story to her child, her voice a lullaby of love and comfort. The child's eyes grow heavy, a world of dreams waiting to unfold.Finally, as the city slumbers, the quiet hum of night owls and the distant rumble of a late-night train remind us that life is a continuous journey, with each day a new chapter to be written.。

六级英语考试段落匹配训练题***一***A： Summary： When home office puters go down， many all businesses grind to a halt. Fortunately， taking steps to recover from dXXsters and mimize their effects is uite straightforward.B： Fires，wer surges， and floods， they're all facts of life. We read about them in the rng paper and see them on the eveng news. We sympathize with the victims and miserate overtheir bad luck. We also shake our heads at the digital conseuences—melted puters， system failures， destroyed data. Yet， somehow， many of us continue to live by that old mantra of deal："It won't happen to me." Well， the truth is， at some int you'll probably he to deal with at least one dXXster. That's just how it goes， and in st aspects of our lives we do somethingabout it. We buy insurance. We stow away provisions. We even make dXXster plans and run drills. But for some reason， puter dXXster recovery is a blind st for many of us. It shouldn't be.Homeputers contain some of our st imrtant information， both business and personal， and making certain our data survives a dXXster should be a priority. reover， even the allestdXXster can be a serious disruption. Personal puters he bee an integral part of the ooth-runng household. We use them to mucate， shop， and do homework， and they're even revital to home office users. When home office puters go down， many all businesses grind to a halt. Fortunately，taking steps to recover from dXXsters and mimize their effects is uitestraightforward. With a good offsite storage plan and the right tools， you can bounce back uickly and easily from minor puter dXXsters. And， should a major calamity strike， you can restassured your data issafe.Offsite Storage： Major DXXstersC： House fires and floods are ang the st devastating causes of personal puter destruction. That's why a solid offsite backup and recovery plan is essential. Although many home usersfaithfully back up their hard drives， many would still lose all their data should their house flood our burn. That's bXXuse they keep their backups in relatively close to their puters.Their backup disks might not be in the same room as their puters—tucked away in a closet or even the garage—butthey're not nearly far enough away should a serious dXXster strike. So， it'simrtant to back up your system to a revable medium and to store it elsewhere.D： There are many ways to approach offsite storage. It starts with chXXe of backup tools and storage medium. DXXster sXXations are stressful， and your recovery tools shouldn't add to thatstress. They must be dependable and intuitive， making it easy to schedule regular backups and to retrieve filesin a pinch. They must also be patible with your chXXe of backup medium.Depending on your tools， you can back up to a variety of durable disk types—from CDs to Jaz drives to rete network servers. Although many of these storage media he high capacity， a backuptool with pression capabilities is a big plus， eliminating the inconveence of multiple disks or large uploads.E： Once you select your tools and a suitable medium， you need to find a rete place to store your backups. The options are endless. However， no matter where you choose， be sure the site issecure， easily accessible， and a good distance away from your home. You may also t to consider using an Internet-based backup service. re and re service providers are offering storagespace on their servers， and uploading files to arete location has bee an attractive alternative to conventional offsite storage. Of course， before using one of these services， makXXrtain you pletely trust the service provider and its security methods. Whatever you do， schedule backups regularly and store them far away from your home.e What May： Handling the Garden Variety puter CrisisF： Not all home puter damage results from physical dXXster. Many less menacing problems can also hobble your PC or destroy your information. Systems crash，kids "rearrange" data， adultsinadvertently delete files. Although these events might not seem calamitous， they can he serious implications. So， once again， it's imrtant to be prepared. As with physical dXXsters，regular backups are essential. However， some of these aller issues reuire a resnse that's re nuanced than XXlesale backup and restoration. To deal with less-than-total dXXster，yourtool set must be both werful and agile. For example，when a all number of files are promised， you may t to retrieve those files alone. Meanwhile， if just your settings are affected，you'll t a simple way to roll back to your preferred setup. Yet， should your operating system fail， you'll need a way to boot your puter and performlarge-scale recovery. puter crisese in all shapes and sizes， and your backup and recovery tools must be flexible enough to meet each llenge.The Right Tools for the Right Job： Gearing up for DXXsterG： When dXXster strikes， the uality of your backup tools can make the difference between utter frustration and peace of mind. Symantec understands this and offers a range of top ualitybackup and recovery solutions. Norton GoBack is the perfect tool for random system crashes， failed installations， and inadvertent deletions. With this werful and conveent solution，it'ssimple to retrieve overwritten files or to bring your system back to its pre-crash state. Norton Ghost is a time-tested home office solution. Euipped to handle full-scale backups， it's alsohandy for clong hard drives and facilitating system upgrades. A forite chXXe for IT professionals， it's the ideal tool for the burgeong home office. You can buy Norton Ghost and NortonGoBack separately， or get them both when you purse Norton System Works.H： Life's dXXsters， large and all， often catch us by surprise. However， with a little planng and the right tools， you can reduce those dXXsters to bumps in the road. So， don't waitanother day. Buy a good set of dXXsterrecovery tools， set up an automatic backup schedule， and perform a dry run every now and again. Then， rest easy.1. You should take steps to recover from puter dXXsters so as to mimize their effects.2. For some reason， puter dXXster recovery is always ignored by many of us.3.

BDirections: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.Answer the questions by marking the corresponding letter on Answer Sheet 2.Can societies be rich and green?[A]"If our economies are to flourish,if global poverty is to be eliminated and if the well-being of the worlds people enhanced—not just in this generation but in succeeding generations—we must make sure we take care of the natural environment and resources on whichour economic activity depends."That statement comes not,as you might imagine,from a stereotypical tree-hugging,save-the-world greenie(环保主义者),but from Gordon Brown,a politician with a reputation for rigour,thoroughness and above all,caution.[B]A surprising thing for the man who runs one of the worlds most powerful economies to say?Perhaps;though in the run-up to the five-year review of the Millennium(千年的)Goals,he is far from alone.The roots of his speech,given in March at the roundtable meeting of environment and energy ministers from the G20 group of nations,stretch back to 1972,and the United Nations Conference on the Human Environment in Stockholm.[C]"The protection and improvement of the human environment is a major issue which affects the well-being of peoples and economic development throughout the world,"read the final declaration from this gathering,the first of a sequence which would lead to the Rio de Janeiro Earth Summit in 1992 and the World Development Summit in Johannesburg three years ago.[D]Hunt through the reports prepared by UN agencies and development groups—many for conferences such as this years Millennium Goals review—and you will find that the linkage between environmental protection and economic progress is a common thread.[E]Managing ecosystems sustainably is more profitable thanexploiting them,according to the Millennium Ecosystem Assessment.But finding hard evidence to support the thesis is not so easy.Thoughts turn first to some sort of global statistic,some indicator which would rate the wealth of nations in both economic and environmental terms and show a relationship between the two.[F]If such an indicator exists,it is well hidden.And on reflection,this is not surprising;the single word"environment"has so many dimensions,and there are so many other factors affecting wealth—such as the oil deposits—that teasing out a simple economy-environment relationship would be almost impossible.[G]The Millennium Ecosystem Assessment,a vast four-year global study which reported its initial conclusions earlier thisyear,found reasons to believe that managing ecosystems sustainably—working with nature rather than against it—might be less profitable in the short term,but certainly brings long-term rewards.[H]And the World Resources Institute(WRI)in its World Resources 2005 report,issued at the end of August,produced several such examples from Africa and Asia;it also demonstrated that environmental degradation affects the poor more than the rich,as poorer people derive a much higher proportion of their income directly from the natural resources around them.[I]But there are also many examples of growing wealth by trashing the environment,in rich and poor parts of the world alike,whether through unregulated mineral extraction,drastic water use for agriculture,slash-and-burn farming,or fossil-fuel-guzzling(大量消耗)transport.Of course,such growth may not persist in the long term—which is what Mr.Brown and the Stockholm declaration were both attempting to point out.Perhaps the best example of boom growth and bust decline is the Grand Banks fishery.For almost five centuries a very large supply of cod(鳕鱼)provided abundant raw material for an industry which at its peak employed about 40,000people,sustaining entire communities inNewfoundland.Then,abruptly,the cod population collapsed.There were no longer enough fish in the sea for the stock to maintain itself,let alone an industry.More than a decade later,there was no sign of the ecosystem re-building itself.It had,apparently,been fished out of existence;and the once mighty Newfoundland fleet now gropes about frantically for crab on the sea floor.[J]There is a view that modern humans are inevitably sowing the seed of a global Grand Banks-style disaster.The idea is that we are taking more out of what you might call the planets environmental bank balance than it can sustain;we are living beyond our ecological means.One recent study attempted to calculate the extent ofthis"ecological overshoot of the human economy",and found that we are using 1.2 Earths-worth of environmental goods and services—the implication being that at some point the debt will be called in,and all those services—the things which the planet does for us for free—will grind to a halt.[K]Whether this is right,and if so where and when the ecological axe will fall,is hard to determine with any precision—which is why governments and financial institutions are only beginning to bring such risks into their economic calculations.It is also the reason why development agencies are not united in their view of environmental issues;while some,like the WRI,maintain that environmental progress needs to go hand-in-hand with economic development,others argue that the priority is to build a thriving economy,and then use the wealth created to tackle environmental degradation.[L]This view assumes that rich societies will invest in environmental care.But is this right?Do things get better or worse as we get richer? Here the Stockholm declaration is ambiguous."In the developing countries,"it says,"most of the environmental problems are caused by under-development."So it is saying that economic development should make for a cleaner world?Not necessarily;"In the industralised countries,environmentalproblems are generally related to industrialisation and technological development,"it continues.In other words,poor and rich both over-exploit the natural world,but for different reasons.Its simply not true that economic growth will surely make our world cleaner.[M]Clearly,richer societies are able to provide environmental improvements which lie well beyond the reach of poorer communities.Citizens of wealthy nations demand nationalparks,clean rivers,clean air and poison-free food.Theyalso,however,use far more natural resources-fuel,water(all those baths and golf courses)and building materials.[N]A case can be made that rich nations export environmental problems,the most graphic example being climate change.As a countrys wealth grows,so do its greenhouse gas emissions.The figures available will not be completely accurate.Measuring emissions is not a precise science, particularly when it comes to issues surrounding land use;not all nations have re-leasedup-to-date data,and in any case,emissions from some sectors such as aviation are not included in national statistics.But the data is exact enough for a clear trend to be easily discernible.As countries become richer,they produce more greenhouse gases;and the impact of those gases will fall primarily in poor parts of the world.[O]Wealth is not,of course,the only factor involved.The average Norwegian is better off than the average US citizen,but contributes about half as much to climate change.But could Norway keep its standard of living and yet cut its emissions to Moroccan or even Ethiopian levels?That question,repeated across a dozen environmental issues and across our diverse planet,is what will ultimately determine whether the human race is living beyond its ecological means as it pursues economic revival.36.Examples show that both rich and poor countries exploited the environment for economic progress.37.Environmental protection and improvement benefit people all over the world.38.It is not necessarily true that economic growth will make our world cleaner.39.The common theme of the UN reports is the relation between environmental protection and economic growth.40.Development agencies disagree regarding how to tackle environment issues while ensuring economic progress.41.It is difficult to find solid evidence to prove environmental friendliness generates more profits than exploiting the natural environment.42.Sustainable management of ecosystems will prove rewarding inthe long run.43.A politician noted for being cautious asserts that sustainable human development depends on the natural environment.44.Poor countries will have to bear the cost for rich nations economic development.45.One recent study warns us of the danger of the exhaustion of natural resources on Earth.参考答案36. 正确选项 I37. 正确选项 C38. 正确选项 L39. 正确选项 D40. 正确选项 K41. 正确选项 E42. 正确选项 G43. 正确选项 A44. 正确选项 N45. 正确选项 J。

2020年六级真题及答案听力Part Ⅱ Listening Comprehension (25 minutes)Section ADirections: In this section, you will hear two long conversations. At the end of each conversation, you will hear some questions. Both the conversation and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A), B), C) and D) . Then mark the corresponding letter on Answer Sheet 1with a single line through the centre. Conversation OneM: Tonight, we have a very special guest (1) Mrs. Anna Sanchez is a three time Olympic champion and author of the new book To the Edge Mrs. Sanchez, thank you for joining us.W: Thank you for having me. M: Let’s start with your book. What does the title To the Edge mean? What are you referring to?W: (2) The book is about how science and technology has helped push humans to the edge of their physical abilities. I argue that in the past 20 years, we have had the best athletes the world has ever seen.M: But is this a fair comparison? How do you know how, say, a football player from 50 years ago would compare to one today? W: Well, you are right. That comparison would be perhaps impossible to make. But the point is more about our knowledge today of human biochemistry, nutrition, and mechanics. (3) I believe that while our bodies have not changed in thousands of years. what has changed is the scientific knowledge. This has allowed athletes to push the limits of what was previously thought possible.M: That’s interesting. Please tell us more about these perceived limits. W: The world is seen sports records being broken that could only be broken with the aid of technology. Whether this be the speed of a tennis serve or the fastest time in a hundred meter dash or 200 meter swimming race.M: (4) Is there any concern that technology is giving some athletes an unfair advantage over others?W: That is an interesting question. And one that has to be considered very carefully. Skis, for example, went from being made of wood to a metal alloy which allows for better control and faster speed. There is no stopping technological progress. But, as I said, each situation should be considered carefully on a case by case basis.Question 1: What do we learn about Anna Sanchez?Question 2: What is the woman’s book mainly about?Question 3: What has changed in the past thousands of years? Question 4: What is the man’s concern about the use of technology in sports competitions?Conversation TwoW: I’ve worked in international trade all my life. My father did so to be for me. So 1 guess you could say it runs in the family.M:What products have you worked with?W:All sorts, really. I’ve imported textiles, machinery, toys, solar panels, all kinds of things over the years. Trends and demand come and go. (5) So one needs to be very flexible to succeed in this industry. M:I see what goods are you trading now?W:I now import furniture from China into Italy and foods from Italy into China.(6)I even use the same container.It’s a very efficient way of conducting trade.M:The same container. You mean you own a 40 foot cargo container? W:Yeah, that’s right. (7)I have a warehouse in Genoa over Italy and another in Shanghai. I source mid century modern furniture from different factories in China. It’s very good value for money. I collet it all in my warehouse and then dispatch it lo my other warehouse in Italy. Over there I do the same, but with Italian foods instead of furniture, things like pasta, cheese, wine, chocolates. And I send allthat to my warehouse in China in the same freight container I use for the furniture.M:So I presume you sell both lines of products wholesale in each respective country.w:Of course. I possess a network of clients and partners in both countries. That’s the main benefit of having done this for so long. I’ve made great business contacts over time.M:How many times do you ship?W: 1 did 12 shipments last year, 18 this year, and I hope to grow to around 25 next year. Thar’s both ways there and back again. Demand for authentic Italian food in China is growing rapidly. And similarly, sales of affordable, yet stylish wooden furniture are also increasing in Italy. (8)Furniture is marginally more profitable, mostly because it enjoys lower customs duties.Question 5: What docs the woman think is required to be successful in international trade?Question 6: What does the woman say is special about her way of doing trade?Question 7: What docs the woman have in both Italy and China? Question 8: What does the woman say makes furniture marginally more profitable?Section BDirections: In this section, you will hear two passages. At the end of each passage, you will hear some ques- tions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A),B), C) and D) . Then mark the corresponding letter on Answer Sheet1 with a single line through the center.Passage OneToo many people view their jobs as as day prison, which they are paroled every Friday, says Joel Goodman, founder of the humor project, a humor consulting group in Saratoga springs, New York. (9) Humor unlocks the office prison because it lets adults bring. some of their childlike spirit to the job, according to Howard Pollio, professor of psychology at the university of Tennessee Knoxville. And office with humor breaks is an office with satisfied and productive employees.(10) Polio conducted a study that proved humor can help workers Excel at routine production tasks. Employees perform better when they have fun. In large corporations with a hierarchy of power, there is often no outlet for stress. Every company needs underground ways of poking fun at the organization, says Lynn and Mark, a speaker on workplace humor for saint Mary’s health center in saint Louis. Kodak Rochester, New York branch, discovered a way for its 20000 employees to uncork their bottled up resentments. There 1000square foot humor room features a toy store. Among the rooms, many stress reducing gadgets, the main attraction is a boss doll with detachable arms and legs. (11) Employees can take the doll apart as long a they put its arms and legs buck in place.Sandy Cohan, owner of a graphic print production business, created the quote board to document the bizarre phrases people say when under strict deadlines, when you’re on distress, you say stupid things, says Cohen. Now we just look at each other and say that’s one for the quote board.Questions9 to 11 are based on the passage you have just heard. Question 9. What docs the passage say about humor in the workplace? Question 10. What does the study by Howard Polio show? Question 11. What can codex employees do in the humor room? Passage Two(12)Public interest was aroused by the latest discovery of a changed gene in obese mice The news was made known by Rockefeller university geneticist Jeffrey Friedman. The researchers believe this gene influences development of a hormone that tells organism how fat or full it is (13)Those with he changed gene may not sense when they have eaten enough or if they have sufficient fatty tissue. and thus can’t tell when to stop eating.The researchers also reported finding a gene nearly identical to the mouse obesity gene in humans. The operation of this gene in humans has not yet been demonstrated, however. (14)Still professionals like university of Vermont psychologist Eyster Ross Bloom reacted enthusiastically. This research indicates that people really are born with a tendency to have a certain weight, just as they are to have a particular skin color or height. Actually, behavioral geneticists believe that less than half of the total weight variation is programmed in the genes, while height is almost entirely genetically determined. Whatever role genes play Americans are getting fatter.A survey by the center for disease control found that obesity has increased greatly over the last 10 years. (15)Such rapid change underlines the role of environmental factors like the abundance of rich foods in Americans overeating. The center for disease control has also found that teens are far less physically active than they were even a decade ago. Excepting that weight is predetermined, can relieve guilt for overweight people. But people’s belief that they cannot control their weight can itself contribute t0 obesity. Questions 12 to 15 are based on the passage you have just heard. Question 12. What does the speaker say has aroused public interest? Question 13. What do we learn about the changed gene?Question 14. What does university of Vermont psychologist Eyster Ross Bloom say?Question 15. What accounts for Americans obesity according to a survey by the center for disease ontrol?Section CDirections: In this section, you will hear three recordings of lectures or talks followed by three or four ques- tions. The recordings will be played only once. After you hear a question, you must choose the best answer from the four choices marked A), B), C) and D) . Then mark the corresponding letter on Answer Sheet 1 with a single line through the center.Recording OneQualities of a relationship such as openness, compassion and mental stimulation, or of concern to most of us regardless of sex. But judging from the questionnaire response, they are more important to women than to men. Asked to consider the ingredients of close friendship, women rated these qualities above all others. (16) Men assigned a lower priority to them in favor of similarity and interest, Selected by 77% of men and responsiveness in a crisis, chosen by 61% of male respondents, mental stimulation ranked 3rd in popularity by men as well as women was the only area of overlap. Among men, only 28% named openness as an important quality.Caring was picked by just 23%. (17) It is evident by their selections that when women speak of close friendships. they are referring to emotional factors. While men emphasized the pleasure they find in a friend’s company, that is, when a man speaks of a friend, he is likely to be talking about someone he does things with, a teammate, a fellow hobbyist, a drinking buddy. These activities are the fabric of the friendship. It is a doing relationships in which similarity in interests is the key bond. This factor was a consideration of less than 11% of women. Women opt for a warm emotional atmosphere where communication flows freely. Activity is mere background.Lastly, men, as we have seen, have serious questions about each other’s loyalty. Perhaps this is why they placed such strong emphasis on responsiveness in a crisis. Someone I can call on for help. Women, as their testimonies indicate, are generally more secure with each other and consequently are more likely to treat this issue lightly. In follow up interviews, this was confirmed numerous times. As woman after woman indicated that being there when needed was taken for granted. (18) As for the hazards of friendship. more than a few relationships have been shattered because of cutthroat competition and feelings of betrayal. This applies t both men and women, but unequally in comparison, nearly twice as many men complained about these issues as women. Further, while competition and betrayalare the main thorns to female friendship: men are plagued in almost equal amounts by two additional issues lack of frankness and a fear of appearing unmanly. Obviously, for a man, a good friendship is hard to find.Question 16: What quality do men value most concerning friendship according to a questionnaire esponse?Question 17: What do women refer to when speaking of close friendships?Question 18: What may threaten a friendship for both men and women?Recording Two(19) The partial skeletons of more than 20 dinosaurs and scattered bones of about 300 more have been discovered in Utah and Colorado at what is now the Dinosaur National Monument. Many of the best specimens may be seen today at museums of natural history in the larger cities of the United States, and Canada. This dinosaur pit is the largest and best preserved deposit of dinosaurs known today. (20) Many people get the idea from the mass of bones in the pit wall that some disaster, such as volcanic explosion or a sudden flood. killed a whole herd of dinosaurs in this area. This could have happened, but it probably did not.The main reasons for thinking otherwise, other scattered bones and the thickness of the deposit in other deposits where the animals were thought to have died together, the skeletons were usually complete and often all the bones were in their proper places. Rounded pieces of fossil bone have been found here. These fragments got their smooth, round shape by rolling along the stream bottom. In a mass killing, the bones would have been left on the stream or lake bottom together at the same level. But in this deposit, the bones occur throughout a zone of sandstone about 12 feet thick.The mixture of swamp dwellers and dry land types also seems to indicate that the deposit is a mixture from different places. The pit area is a large dinosaur graveyard-not a place where they died. (21) Most of the remains probably floated down eastward flowing river until they were left on a shallow sandbar. Some of them may have come from faraway dry land areas to the west. Perhaps they drowned trying to cross a small stream, all washed away during floods. Some of the swamp dwellers may have got stuck in the very sandbar that became their grave. Others may have floated for miles before being stranded.Even today, similar events take place: When floods come in the spring, sheep, cattle, and deer are often trapped by rising waters and often drown. Their dead bodies float downstream until the flood recedes,and leaves them stranded on a bar or shore where they lie, half buried in the sand until they decay, Early travelers on the Missouri River reported that shores and bars often lined with the decaying bodies of buffalo that had died during spring floods.Question 19: Where can many of the best dinosaur specimens be found in North America?Question 20: What occurs to many people when they see the massive bones in the pit wall?Question 21: What does the speaker suggest about the large number of dinosaur bones found in the pit?Recording ThreeI would like particularly to talk about the need to develop a new style of aging in our own society. (22)Young people in this country have been accused of not caring for their parents the way they would have in the old country. And this is true. (23) But i is also true that old people have been influenced by an American ideal of independence and autonomy. So we live alone, perhaps on the verge of starvation, in time without fiends. But we arc independent. This standard American style has been forced on every ethnic group. Although there are many groups for whom the ideal is not practical, it is a poor ideal and pursuing it docs a great deal of harm. This ideal of independence also contains a tremendous amount of unselfishness.In talking to today ’s young mothers, I have asked them what kind of grandmothers they think they are going to be. I hear devoted loving mothers say that when they are through raising their children, they have no intention of becoming grandmothers. (24) They are astonished to hear that in most of the world. throughout most of its history, families have been three or four generation-families Jiving under. the same roof. We have over-emphasized the small family uni—father, mother, small children. We think it is wonderful if grandma and grandpa, if they’re still alive, can live alone. We have reached the point where we think the only thing we can do for our children is to stay out of their way.

2020年大学英语四级阅读段落信息匹配训练(2)Why I Became a Teacher： to Pass on My Love of LiteratureA) Like lots of people, I never thought I'd be a teacher when I was at school. To be honest l only did my training because my husband was on a four-year course and 1was on a three-year course at Cardiff University so I wanted to do something for one year. I thought doing a teaching qualification would be interesting and might be quite usefull I'm convinced that nothing else I might have done would have given me so much pleasure and satisfaction, or fitted in so well with family life.B) When I retire, in just a few years time, I can look back on a career which made a positive difference to thelives of thousands of children. Few other career choices can be so rewarding, so if you have a love of your subject and want the opportunity to pass that on then teaching can be a great career.C) Anyone going into teaching now will be used to teaching to formal work schemes and observation. I think it has raised standards in the profession but personally I feel the loss in the classroom. I've got the confidence of 30 years experience. I've seen new approaches come and go (and sometime even identical "new ideas" come and go more than once).D) For me, it's the passion for your subject and interest in the success of your students that matters more than howall the acronyms (首字母缩略词) add up. This is what will make you a good teacher. There's still room for individualsbut you have to have the confidence and passion for your subject to make it work.E) The major challenge in teaching is time. There's not enough of it. It's hard if you're working full time to cope with the marking and feel Eke you have enough time to do your job properly. I've worked part time ever since I had children.I officially work three days a week--trot on my two days offI always work, it probably all adds up to what counts as afull week's work in most other jobs but the pay isn't bad so you can work part time and then the job really does fit inwith family life. There are shortcuts to save time, and ifhad to work part time I'd have to use. them. But working part time gives me the luxury, to be a critical marker. It cantake two hours to mark a 3,000 word A level essay, so if you have 16 pupils that's 32 hours of marking in one week forjust one class.F) One of the benefits of being a part-time teacher isthat I do have time to mark properly. Sometimes my feedbackis almost as long as their essay but 1 really want the kidsto do well. One of the best things about teaching is you getto raise children's aspirations, and to make a difference in their lives. You get visits and emails from your old students to prove it! It's great to make the difference, and, as they say, it does make it all worthwhile.G ) The core of teaching is the subject and the pupils.We have a lot of NQTs and PGCE students coming to our school and sometimes I must admit to being disappointed whenstudents don't know their subjects that well. I had an NQTwho was teaching Animal Farm and asked me "What's Marxism?" --and she'd got a first in her degree so it just goes to show that government initiatives to try and attract those with firsts aren't necessarily going work.H) However. lots of people drop out of teaching after a couple of years, it is an exhausting job. So my advice to those just starling out is：I) Don't lose your sense of proportion over things that happen in the classroom or in an observation that doesn't go well. As long as in the higger picture of things you are connecting with kids and the subject--then don't get frustrated. Even after 30 years of teaching everyone has fearful days in teaching, he you think： "Can I really do this?"You've got In keep positive; it's only a problem if you gel mute bad days than good days.J)Make sure leaching doesn't overwhelm you. You have Io develop strategies especially if you are teaching a subject which requires a lot of marking. So plan things well. Get your pupils to do peer marking, which really can work. If you know you just can't handle any more marking in a particular week, get pupi!s to write a speech and then perform it in the next class. You've got to think ahead about times of maximum workload and plan accordingly--ask your more experienced colleagues for adviceK)You've got to keep your sense of burnout, which is a great v, ay of relieving a,situation. I know I became abetter teacher when I became a parent. I realised that kids can be so unpleasant sometimes, even your own kids. Theydon't mean it; they're just being kids. It doesn't mean they bate you or hate your lessons, When you're a new teacher。

2020英语六级段落匹配题专项练习题(2)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 e only two font styles per slide—one for the title and the otherfor 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 thetext body.D) Embed the fonts in your presentation, if you are not sure whether the fonts used in the presentation are presentin 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+F3until 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 a dark-colored background and use any light color for text. Minimize the use of “bells and whistles” such as sound effects, “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 flash and motion can distract and annoy viewers. Do not rely too heavily 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。

2020年12月英语六级长篇阅读匹配题

2020年12月英语六级长篇阅读匹配题Can Your Still Work Your Way through College?A. The American Dream refers to the idea that a person has the opportunity to succeed and prosper, despite their economic or social backgrounds, through hard work. But if the rising cost of tuition prohibits students from working through college, Can the American Dream still be obtained?B. Thirty years ago, the cost of tuition was low enough at most public universities that students could pay their way through school by working throughout college. But since the average cost of attendance for all 4-year public universities within a given state rises each year, this is now an almost impossible feat (功绩) . 80 percent of students work at least part-time during college. Recently the question of whether or not working your way through school has become a "thing of the past" was raised by Randy Olson, a graduate student at Michigan State University, who decided to investigate the issue at his own university.C. His research found that in 1979 at MSU, a student could work one day for any minimum wage job (8.44hours) at $2.90 per hour to pay for one credit hour of school. In 2020, the same student would have to work 60 hours to.pay for one credit hour based on the minimum wage of $7.25 per hour.D. The average price of tuition at 4-year public universities rose 2.9% in 2020. This was the smallest tuition increase in nearly 30 years. Since 2004, the average cost of attending a public university in a given state hascontinuously increased as well. Minimum wage only rose in ten states in 2020, while tuition went up in every state.E. With these numbers in mind, it's no surprise some students are working almost full time to pay for school. Ryan Rose, a sophomore at the University of Southern California, works about 30 hours a week to pay for his expenses.While .the university covers his cost of attendance, he still feels the need to work to cover the high cost of living in Los Angeles. "If I went to school at home, I would have expenses that are more fun based, rather than things like buying food and paying rent," he says. "But I felt the educational appeal of USC was going to give me more money in the long run."F. As a production manager for USC's "Trojan Events and Services," Rose handles the logistics of booking and planning events on USC's campus. Since his job reflects highly on the university, he feels a need to prioritize his work over other aspects of college. "It's changed my college experience because it creates stress that students who aren't working don't think about," Rose says. "There are times where I have to decide if an event is more important than a homework assignment because I care about the university's image."G. Courtney Williams, a sophomore at Fullerton College, works three separate jobs to pay her way through community college. "I work about 45 hours per week. I wouldn't have three jobs if it weren't for the high cost of school. I'm paying my own way through college...I keep up with my studies but I feel like I lose out on college experiences," Williams says.H. Williams is transferring to Cal State Fullerton in the fall, using money she's saved up during her first two yearsat community college. "I got into all the schools I wanted when I applied in high school, but I didn't have enough money at the time. If the cost of college wasn't so high, maybe I could only work one job like a normal student," Williams says.I. Although Olson's data do not analyze the costs of private schools such as USC, he did broaden his research to include all public four-year universities in the U.S. Olson analyzed the rising cost of tuition from 1987 to 2020 atthese schools and found very similar results. After adding a linear regression analysis to find tuition costs in 1979, he found that 182 hours a year could pay for a student's tuition in full. In 2020, it would take 991 hours to pay for the same year of school. But all of Olson's data only take into account the cost of tuition, meaning he does not include the cost of food, rent, books and general living expenses.J. Working 30 hours a week allows students like Rose to pay for expenses outside of tuition. Although Rose'sfinancial aid package includes a work-study allotment (勤工俭学助学金), this isn't enough to cover his college costs outside of tuition. "If my company limited my hours to my work-study allotment I wouldn't be able to attend school because I wouldn't have enough money. I get the same work-study allotment as some of my friends who live in much cheaper states where the cost of living is much less than it is in California," Rose says.K. Rose considered the high cost of living in Los Angeles while choosing colleges, but he ultimately decided theeducational benefits of a private school in an expensive city would outweigh the costs. "I was offered enough aid to be paid at state universities, but the educational appeal of USC will give me more money in the long run," Rose says.L. So how does the number of hours students work to pay for school change their college experience? Mary Tomlinson graduated from the University of Florida's College of Journalism and Communications in 1984. With no funding from her family and just a small grant from the school, she had to work her way through college. But her experience was very different from Rose's. "I went off to college with no moneyin the bank, but I was able to cover all my costs by working because the cost wasn't as high as it is today," Tomlinson says.M. Tomlinson worked in the mathematics department throughout college but she also picked up another job at the local television station during her junior year. She took unpaid jobs at the school radio station and televisionstation to gain experience in her field. "There wasn't as much pressure to be well-rounded ... you didn't need community involvement and leadership and all those things, so that allowed me to solely focus on working," she says.N. As a current student, Rose agrees that work candetract from his ability to be involved in extracurricular activities. "I can't be involved in other things because of how much I work. There are times when I see my friends who are involved in clubs and I think I wish I had time for that; but I'm happy that I have my job because I'm gaining things they could never gain," Rose says.O. As a marketing director who looks at several graduating students' resumes, Tomlinson believes current students need to make time for both work and school. "Working a few hours is a good thing because it broadens your knowledge base.., the danger is when it becomes so many hours that it impacts your schoolwork," she says. "It's ideal to have a healthy balance in between." But with the rising cost of tuition, this healthy balance seems to present challenges for modern students.46. Olson's study is limited since it only incorporates the data on the cost of tuition in public universities in the U.S.47. To some students like Ryan Rose, working part-time cannot cover all the cost of school.48. Mary Tomlinson suggests that current students should deal with the relationship between work and study in a better way.49. Ryan Rose supposes that studying in some state universities will yield less rewards than in such private universities as USC.50. Mary Tomlinson believes that there was less demandfor developments in all aspects thirty years ago.51. The rise of minimum wage is limited compared to the continuous and nationwide increase in the cost of tuition.52. Ryan Rose holds the idea that his work can compensate for what he has lost in campus activities.53. To Ryan Rose, study sometimes has to give way to work because his work can impact the USC's image.54. Ryan Rose's work-study allotment is less helpful to him than his friends' due to regional differences in the cost of living.55. Courtney Williams believes that the high cost of school makes her college life different from others'.。

2020年大学英语六级长篇阅读匹配练习题(2)Genetically Modified Foods--Feed the World?[A] If you want to spark a heated debate at a dinner party, bring up the topic about genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions--and vocal green lobbies--the idea seems against nature.[B] In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the U. S. last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the U. S. this year. The genetic is out of the bottle.[C] Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from--and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations; the issue is simpler and much more urgent： Do the benefits of biotech outweigh the risks?[D] The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. And by 2050, the UN estimates, it will be probablynear 9 billion. Almost all that growth will occur in developing countries. At the same time, the world's available cultivable land per person is declining. Arable land has declined steadily since 1960 and will decrease by half over the next 50 years, according to the International Service for the Acquisition of Agri-Biotech Applications ( ISAAA).How can biotech help?[E] Biotechnologists have developed genetically modified rice that is fortified with beta-carotene(胡萝卜素)--which the body converts into vitamin A--and additional iron, and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attribution to pests, drought, poor soil and crop viruses, bacteria or fungi ( 真菌 ).[F] Damage caused by pests is incredible. The European corn borer, for example, destroys 40 million tons of the-world's corn crops annually, about 7% of the total. Incorporating pest-resistant genes into seeds can help restore the balance. In trials of pest-resistant cotton in Africa, yields have increased significantly. So far, fears that genetically modified, pest-resistant crops might kill good insects as well as bad appear unfounded.[G] Viruses often cause massive failure in staple cropsin developing countries. Two years ago, Africa lost more than half its cassava (树薯) crop--a key source of calories-to the mosaic virus (花叶病毒).Genetically modified, virus-resistant crops can reduce that damage, as can drought-tolerant seedsin regions where water shortages limit the amount of landunder cultivation. Biotech can also help solve the problem of soil that contains excess aluminum, which can damage roots and cause many staple-crop failures. A gene that helps neutralize aluminum toxicity (毒性) in rice has been identified. Many scientists believe biotech could raise overall crop productivity in developing countries as much as 25% and help prevent the loss of those crops after they are harvested.[H]Yet for all that promise, biotech is far from being the whole answer. In developing countries, lost crops are only one cause ofhunger. Poverty plays the largest role. Today more than 1 billion people around the globe live on less than 1 dollar a day. Making genetically modified crops available will not reduce hunger if farmers cannot afford to grow them or if the local population cannot afford to buy the food those farmers produce.[I] Biotech has its own "distribution" problems. Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops. Their products are often too costly for poor farmers in the developing world, and many of those products won't even reach the regions where they are most needed. Biotech firms have a strong financial incentive to target rich markets first in order to help them rapidly recoup the high costs of product development. But some of these companies are responding to needs of poor countries.[J] More and more biotech research is being carried outin developing countries. But to increase the impact of genetic research on the food production of those countries,。

长篇阅读一：Paper--More than Meets the EyeA) We are surrounded by so much paper and card that it is easy to forget just how complex it is. There are many varieties and grades of paper materials, and whilst it is fairly easy to spot the varieties, it is far more difficult to spot the grades.B) It needs to be understood that most paper and card is manufactured for a specific purpose, so that whilst the corn-flake packet may look smart, it is clearly not something destined for the archives. It is made to look good, but only needs a limited life span. It is also much cheaper to manufacture than high grade card.C) Paper can be made from an almost endless variety of cellulose-based material which will include many woods, cottons and grasses or which papyrus is an example and from where we get the word "paper". Many of these are very specialized, but the preponderance of paper making has been from soft wood and cotton or rags, with the bulk being wood-based.Paper from WoodD) In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery and then boiled with strong alkalies such as caustic soda, until a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made, relying on the bonding together of the cellulose into layers. That, in a very small nutshell, is the essence of paper making from wood. However, the reality is rather more complicated. In order to give us our white paper and card, the makers will add bleach and other materials such as china clay and additional chemicals.E) A further problem with wood is that it contains a material that is not cellulose. Something called lignin. This is essential for the tree since it holds the cellulose fibres together, but if it is incorporated into the manufactured paper it presents archivists with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look rather brown and careworn. We have all seen this in old newspapers and cheap paperback books. It has beenestimated that most paper back books will have a life of not greater than fifty years. Not what we need for our archives.F) Since the lignin can be removed from the paper pulp during manufacture, the obvious question is "why is it left in the paper?" The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tree to some 95%. Removing it means a yield of only 35%. It is clearly uneconomic to remove the lignin for many paper and card applications.G) It also means, of course, that lignin-free paper is going to be more expensive, but that is nevertheless what the archivist must look for in his supplies. There is no point whatsoever in carefully placing our valuable artifacts in paper or card that is going to hasten their demise. Acid is particularly harmful to photographic materials, causing them to fade and is some cases simply vanish!H) So, how do we tell a piece of suitable paper or card from one that is unsuitable? You cannot do it by simply looking, and rather disappointingly, you cannot always rely on the label. "Acid-free" might be true inasmuch as a test on the paper may indicate that it is a neutral material at this time. But lignin can take years before it starts the inevitable process of breaking down, and in the right conditions it will speed up enormously.I) Added to this, as I have indicated earlier, paper may also contain other materials added during manufacture such as bleach, china clay, chemical whiteners and size. This looks like a bleak picture, and it would be but for the fact that there are suppliers who will guarantee the material that they sell. If you want to be absolutely sure that you are storing in, or printing on, the correct material then this is probably the only way.J) Incidentally, acids can migrate from material to material. Lining old shoe boxes with good quality acid-free paper will do little to guard the contents. The acid will get there in the end.Paper from RagK) Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free, but because there is much less cotton and rag than trees, it also tends to be much more expensive than wood pulp paper. You will still need to purchase from a reliable source though, since even rag paperand card can contain undesirable additives.L) A reliable source for quality rag papers is a recognized art stockiest. Many water color artists insist on using only fine quality rag paper and board.M) The main lesson to learn from this information is that you cannot rely on purchasing archival materials from the high street. The only safe solution is to purchase from specialist suppliers. It may cost rather more, but in the end you will know that your important and valuable data and images have the best home possible.1. The corn-flake packet is cheaper than high grade card.2. There are a lot of materials which can be used for making paper, but the superiority ones are soft wood, cotton and rags.3. During the whole manufacturing process, the final product is made from a pulp of cellulose fibres.4. In order to make white paper and card, the makers will add bleach.5. Liguin is essential for the tree but it will make paper easy to break.6. Many paper producers will preserve lignin during manufacture, because leaving the lignin will make more paper from a tree.7. Acid is particularly harmful to photographic materials.8. If the lignin is removed from the paper, the paper will be more expensive.9. Although free of lignin, paper made from cotton and rag waste can also cost more money than wood pulp paper because there is much less cotton and rag than trees.10. What we can learn from "Paper from Rag" is that you had better buy archival materials from specialist suppliers.长篇阅读二：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 makingmore 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 a dark-colored background and use any light color for text. Minimize the use of “bells and whistles”such as sound effects, “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 flash and motion can distract and annoy viewers. Do not rely too heavily 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 alwaysopen 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 laser 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.

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 bloodglucose 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 in lower 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 a smoker 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 the treatment 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.
