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。
六级考试段落匹配训练题及答案
六级考试段落匹配训练题及答案六级考试段落匹配训练题原文A: Pizza Hut was started in 1958, by two brothers in Wichita, Kansas. Frank and Dan Carney had the idea to open a pizza parlor. They borrowed $600 from their mother, and opened the very first Pizza Hut. In 1959,the first franchise unit opened in Topeka, Kansas. Almost a decade later,Pizza Hut would be serving one million customers a week in their 310 locations. In 1970, Pizza Hut was put on the New York Stock Exchange under the ticker symbol PIZ.B: In 1986, Pizza Hut introduced delivery service, something no other restaurant was doing. By the 1990s Pizza Hut sales had reached $4 billion worldwide. In 1998, Pizza Hut celebrated their 40th anniversary,and launched their famous campaign "The Best Pizzas Under One Roof." In 1996, Pizza Hut sales in the United States were over $5 million. Out of all the existing pizza chains, Pizza Hut had the largest market share,46.4%. However, Pizza Huts market share has slowly eroded because of intense competition from their rivals Dominos, Little Caesars and newcomer Papa Johns. Home delivery was a driving force for success,especially for Pizza Hut and Dominos.C: However, this forced competitors to look for new methods of increasing their customer bases. Many pizza chains decided to diversify and offer new non-pizza items such as buffalo wings, and Italian cheesebread. The current trend in pizza chains today is the same. They all try to come up with some newer, bigger, better, pizza for a low price. Offering special promotions and new pizza variations are popular today as well. For example, chicken is now a common topping found on pizzas.D: In the past, Pizza Hut has always had the first mover advantage. Their marketing strategy in the past has always been to be first. One of their main strategies that they still follow today is the diversification of the products they offer. Pizza Hut is always adding something new to their menu, trying to reach new markets. For example, in 1992 the famous buffet was launched in Pizza Hut restaurants worldwide. They were trying to offer many different food items for customers who didnt necessarily want pizza.E: Another strategy they used in the past and are still using is the diversification of their pizzas. Pizza Hut is always trying to come up with some innovative way to make a pizza into something slightly different - different enough that customers will think its a whole new product. For example,lets look at some of the pizzas Pizza Hut has marketed in the past. In 1983, Pizza Hut introduced their Pan Pizza, which had a guarantee of being ready to eat in 5 minutes when dining at Pizza Hut restaurants. In 1993, they introduced the "BigFoot," which was two square feet of pizza cut into 21 slices. In 1995, they introduced "Stuffed Crust Pizza," where the crust would be filled with cheese. In 1997, they marketed "The Edge," which had cheese and toppings all the way to the edge of the pizza. Currently, they are marketing "The Big NewYorker," trying to bring the famous New York style pizza to the whole country.F: Another opportunity that Pizza Hut has is their new ordering online system. Anyone with Internet access can order whatever they wish and get it delivered to their house without even speaking to someone. This program has just been started, so we do not have any numbers to support whether or not it will be a success.G: Lastly, Pizza Hut has always valued customer service and satisfaction. In 1995, Pizza Hut began two customer satisfaction programs:a 1-800 number customer hotline, and a customer call-back program. These were implemented to make sure their customers were happy, and always wanted to return. In our plan, we will first give a situation analysis of current and relevant environmental conditions that affect our plan. Next, we will give a brief analysis of the current fast food industry,and any trends or changes that might occur in the future.H: However, the fact that Pizza Hut does have a restaurant to run is also a weakness. Pizza Hut has higher overhead costs, due to the restaurant that other competitors dont have to deal with. Another result of higher overhead costs is higher prices Pizza Hut must charge. Obviously,Pizza Hut is not the low cost producer. They rely on their quality pizza and good service to account for their higher prices.I: An indirect weakness that Pizza Hut has is that they have lost a lot of their customers and market share due to such intense competition with competitors. Pizza Huts opportunities are almost endless. They can increase revenue with their new innovative pizzas, and increase brand loyalty with good customer service.J: Pizza Huts number one threats are from their competitors. Currently, their closest competitor is Dominos Pizza. Dominos maincompetitive advantage over Pizza Hut is their price. It is generally lower than Pizza Hut. Also, Dominos was very profitable when they ran the promotional deal of delivering a pizza within 30 minutes. However, many lawsuits have been filed against Dominos in the past for reckless driving by their drivers, so Dominos withdrew the promotion. Little Caesars is another one of Pizza Huts competitors, right behind Dominos in market share. Little Caesars is famous for offering large quantities of pizza for less money. Other competitors include Papa Johns, Sbarro, and Pizza Inn.K: A problem facing all of the pizza chains is that each of their individual competitive advantages are pretty much everyones competitive advantages. Most if not all the top pizza chains offer free delivery,and always have some sort of promotional deal offering large pizzas at reduced prices. Other competitors to take into consideration are frozen pizzas and make-it-yourself pizzas that are purchased in grocery stores. Some examples of these are Tombstone Pizzas, Boboli, and DiGornio pizzas. 六级考试段落匹配训练题选项1. Pizza Hut expanded its business into many parts of the country by the time of 1969.2. Pizza Hut has not always dominated the market.3. buffalo wings, and Italian cheese bread are now commonly served at pizza restaurants.4. The diversification strategy is not to be the first mover.5. In Pizza Hut, a Pan Pizza was guaranteed to serve in 5 minutes.6. If you want a pizza from Pizza Hut delivered directly to your house,you have to have Internet access in the first place.7. In order to make sure their customers were happy, Pizza Hut introduced two customer satisfaction programs.8. The higher overhead costs of Pizza Hut obviously accounted for higher prices of their pizzas.9. The reason why Dominos withdrew their promotion was that they suffered legally from reckless driving by their drivers.10. Major pizza makers have to face the problem that their competitive advantages are the same.六级考试段落匹配训练题答案1. A2. B3. C4. D5. E6. F7. G8. H9. J10. K六级考试段落匹配训练题及答案相关。

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 1 to 10 are based on the following passage.Music and LanguageMusic and language are two different ---1--- that are often linked together. For example, they both involve a type of communication and have a ---2--- impact on our emotions. However, music and language are fundamentally different in a number of ways.Unlike language, which is composed of words and grammar, music is a ---3--- art form. It uses tones, melodies, rhythms, and harmonies to create emotional ---4---. Language, on the other hand, mainly conveys meaning through the use of words and sentences.Another difference between music and language is their development in humans. ---5--- learn language through exposure to conversations and practice, while music seems to be ---6---. We all have the ability torecognize and appreciate music, even without any formal training. This suggests that our musical abilities may be innate.Furthermore, music and language are processed in different areas of the brain. Language is mainly processed in the left hemisphere, whereas music is ---7--- in both the left and right hemispheres. Evidence has shown that certain ---8--- patients who have lost their ability to speak can still sing, indicating that music may be connected to different neural pathways (神经通路) than language.Despite their differences, music and language are closely related in some ways. Studies have shown that music can assist with language ---9---. For example, listening to music can help ESL students improve their pronunciation and intonation. Similarly, playing a musical instrument can enhance the linguistic abilities of children.In conclusion, while music and language share certain similarities in terms of communication and emotional impact, they also have distinct characteristics. Understanding the differences and connections between music and language can help us appreciate the beauty and uniqueness of each art form.1. [A] skills [B] forms [C] techniques [D] systems2.

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.Questions 11 to 15 are based on the following passage.Do You Prefer to Stay Single?A. It’s often said that a woman who puts a high priority on her career ends up lying alone on a Saturday night. However, my research on this subject shows that it is basically a myth. In fact, in my surveys I found that highly educated career women are just as likely to form successful marriages as other women, and actually more likely to make a good choice the second time around. By contrast, women who don’t care quite so much about their career and are more willing to settle for less than Mr. Right are more likely to end up single.B. Is marrying for love a good or bad thing? Most of us, it seems, would say, “Good, of course!” But are we really thinking? In reality, marrying purely for love may be less likely to lead to a satisfying marriage. Many psychologists now believe that people who expect marriage to provide happiness are often disappointed. Marrying who we fall in love with is a romantic idea. But psychologists have found it often means falling in love with someone like ourselves and who is familiar to us. Love and passion are often considered separate from friendship and companionship (交往、友谊).C. According to the latest research, newlyweds who feel good abouttheir marriage are healthier than those who don’t. The work is one of thefirst of its kind to show how much influence someone’s thoughts can haveon their health. Researchers measured the heart rate, blood pressure, and cholesterol (胆固醇) levels of 28 married women as they argued with their husbands and measured the levels of a chemical (化学物质) linked to heart disease. The women were asked before having a disagreement if they were happy in their marriages. When the researchers reviewed the results, they discovered that the women who said they had happier marriages also had lower levels of the chemical than those who said their marriages weren’t going well.D. It is a cultural stereotype that young women like to date older men. In a study of 18 to 24-year-old college students, researchers found that about 80% of men were interested in dating women who were significantly younger, while 85% of women were keen on dating older men. Many participants explained this interest in terms of desire for maturity, not money.E. In the past, people routinely built relationships with neighbors, families, and communities. Now, however, only two in 10 Americans indicate that they regularly spend time with their neighbors, and only one-third of Americans report regularly spending time with their families. Loneliness, experts now suggest, is twice as deadly as obesity (肥胖) and is as harmful as smoking 15 cigarettes a day. Additionally, loneliness can have a long-term impact on both physical and emotional health, increasing the risk for heart disease, depression, and premature death.F. In a research team studying married couples, researchers asked couples whether they felt close to their partners and if they had thought about separating from them. When the researchers reviewed the magnetic resonance imaging (磁共振成像) scans of the participants’ brains, they found that those who had thought about leaving their partners showed activity in the brain regions associated with a variety of negative emotions, such as anger and sadness. On the other hand, couples who felt close and secure with their partners showed greater activation in areas of the brain associated with reward and attachment.11. Couples who feel happy about their marriage have better health.12. Men tend to be interested in dating younger women, while women prefer older men.13. Good family relationships are becoming less common nowadays.14. Love marriages may not always lead to satisfactory marriages.15. People who put a high priority on their careers are less likely to end up single.答案1. B2. A3. C4. A5. D6. B7. C8. C9. A10. B11. C12. D13. E14. B15. A以上是关于大学英语六级阅读理解题目及答案的内容。
2021年6月英语六级阅读真题及答案 第2套 段落匹配_2
2021年6月英语六级阅读真题及答案第2套段落匹配Grow Plants Without Water[A]Ever since humanity began to farm our own food, we've faced the unpredictable rain that is both friend and enemy. It comes and goes without much warning, and a field of lush (茂盛的) leafy greens one year can dry up and blow away the next. Food security and fortunes depend on sufficient rain, and nowhere more so than in Africa, where 96% of farmland depends on rain instead of the irrigation common in more developed places. It has consequences: South Africa's ongoing drought-the worst in three decades-will cost at least a quarter of its corn crop this year.[B]Biologist Jill Farrant of the University of Cape Town in South Africa says that nature has plenty of answers for people who want to grow crops in places with unpredictable rainfall. She is hard at work finding a way to take traits from rare wild plants that adapt to extreme dry weather and use them in food crops. As the earth's climate changes and rainfallbecomes even less predictable in some places, those answers will grow even more valuable. "The type of farming I'm aiming for is literally so that people can survive as it's going to get more and more dry," Farrant says.[C]Extreme conditions produce extremely tough plants. In the rusty red deserts of South Africa, steep-sided rocky hills called inselbergs rear up from the plains like the bones of the earth. The hills are remnants of an earlier geological era, scraped bare of most soil and exposed to the elements. Yet on these and similar formations in deserts around the world, a few fierce plants have adapted to endure under ever-changing conditions.[D]Farrant calls them resurrection plants (复苏植物). During months without water under a harsh sun, they wither, shrink and contract until they look like a pile of dead gray leaves. But rainfall can revive them in a matter of hours. Her time-lapse (间歇性拍摄的) videos of the revivals look like someone playing a tape of the plant's death in reverse.[E]The big difference between "drought-tolerant" plants and these tough plants: metabolism. Many different kinds of plants have developed tactics to weather dry spells. Some plants store reserves of water to see them through a drought;others send roots deep down to subsurface water supplies. But once these plants use up their stored reserve or tap out the underground supply, they cease growing and start to die. They may be able to handle a drought of some length, and many people use the term "drought tolerant" to describe such plants, but they never actually stop needing to consume water, so Farrant prefers to call them drought resistant.[F]Resurrection plants, defined as those capable of recovering from holding less than 0.1 grams of water per gram of dry mass, are different. They lack water-storing structures, and their existence on rock faces prevents them from tapping groundwater, so they have instead developed the ability to change their metabolism. When they detect an extended dry period, they divert their metabolisms, producing sugars and certain stress-associated proteins and other materials in their tissues. As the plant dries, these resources take on first the properties of honey, then rubber, and finally enter a glass-like state that is "the most stable state that the plant can maintain," Farrant says. That slows the plant's metabolism and protects its dried-out tissues. The plants also change shape, shrinking to minimize the surface area through which their remaining water might evaporate. They can recover frommonths and years without water, depending on the species.[G]What else can do this dry-out-and-revive trick? Seeds-almost all of them. At the start of her career, Farrant studied "recalcitrant seeds (顽拗性种子)," such as avocados, coffee and lychee. While tasty, such seeds are delicate-they cannot bud and grow if they dry out (as you may know if you've ever tried to grow a tree from an avocado pit). In the seed world, that makes them rare, because most seeds from flowering plants are quite robust. Most seeds can wait out the dry, unwelcoming seasons until conditions are right and they sprout (发芽). Yet once they start growing, such plants seem not to retain the ability to hit the pause button on metabolism in their stems or leaves.[H]After completing her Ph. D. on seeds, Farrant began investigating whether it might be possible to isolate the properties that make most seeds so resilient (迅速恢复活力的) and transfer them to other plant tissues. What Farrant and others have found over the past two decades is that there are many genes involved in resurrection plants' response to dryness. Many of them are .the same that regulate how seeds become dryness-tolerant while still attached to their parent plants. Now they are trying to figure out what molecular signalingprocesses activate those seed-building genes in resurrection plants-and how to reproduce them in crops. "Most genes are regulated by a master set of genes," Farrant says, "We're looking at gene promoters and what would be their master switch."[I]Once Farrant and her colleagues feel they have a better sense of which switches to throw, they will have to find the best-way to do so in useful crops. "I'm trying three methods of breeding," Farrant says: conventional, genetic modification and gene editing. She says she is aware that plenty of people do not want to eat genetically modified crops, but she is pushing ahead with every available tool until one works. Farmers and consumers alike can choose whether or not to use whichever version prevails: "I'm giving people an option."[J]Farrant and others in the resurrection business got together last year to discuss the best species of resurrection plant to use as a lab model. Just like medical researchers use rats to test ideas for human medical treatments, botanists use plants that are relatively easy to grow in a lab or greenhouse setting to test their ideas for related species. The Queensland rock violet is one of the best studied resurrection plants so far, with a draft genome (基因图谱) published last year bya Chinese team. Also last year, Farrant and colleagues published a detailed molecular study of another candidate, Xerophyta viscosa, a tough-as-nail South African plant with lily-like flowers, and she says that a genome is on the way. One or both of these models will help researchers test their ideas-so far mostly done in the lab-on test plots.[K]Understanding the basic science first is key. There are good reasons why crop plants do not use dryness defenses already. For instance, there's a high energy cost in switching from a regular metabolism to an almost-no-water metabolism. It will also be necessary to understand what sort of yield farmers might expect and to establish the plant's safety. "The yield is never going to be high," Farrant says, so these plants will be targeted not at Iowa farmers trying to squeeze more cash out of high-yield fields, but subsistence farmers who need help to survive a drought like the present one in South Africa. "My vision is for the subsistence farmer," Farrant says. "I'm targeting crops that are of African value."36. There are a couple of plants tough and adaptable enough to survive on bare rocky hills and in deserts.37. Farrant is trying to isolate genes in resurrection plants and reproduce them in crops.38. Farmers in South Africa are more at the mercy of nature, especially inconsistent rainfall.39. Resurrection crops are most likely to be the choice of subsistence farmers.40. Even though many plants have developed various tactics to cope with dry weather, they cannot survive a prolonged drought.41. Despite consumer resistance, researchers are pushing ahead with genetic modification of crops.42. Most seeds can pull through dry spells and begin growing when conditions are ripe, but once this process starts, it cannot be held back.43. Farrant is working hard to cultivate food crops that can survive extreme dryness by studying the traits of rare wild plants.44. By adjusting their metabolism, resurrection plants can recover from an extended period of drought.45. Resurrection plants can come back to life in a short time after a rainfall.36.C37.H38.A39.K40.E41.I42.G43.B44.F45.D。

六级英语考试段落匹配试题一A We are surrounded by so much paper and card that it is easy to forget just how plex it is. There are many varieties and grades of paper materials, and whilst it is fairly easy to stthe varieties, it is far re difficult to st the grades.B It needs to be understood that st paper and card is manufactured for a specific purse, so that whilst the corn-flake packet may look art, it is clearly not something destined for thearchives. 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 alst 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 theword "paper". Many of these are very specialized,but the prenderance 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 werful machinery and then boiled with strong alkalies such as caustic soda,until a fine pulp ofcellulose 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 all nutshell, is the essenceof paper making from wood. However, the reality is rather re plicated. In order to give us our white paper and card, the makers will add bleach and other materials such as china clay andadditional chemicals.E A further problem with wood is that it contains a material that is not cellulose. Something called lign. This is essential for the tree since it holds the cellulose fibres together, butif it is incorrated into the manufactured paper it presents archivists with a problem. Lign eventually breaks down and releases acid products into the paper. This will weaken the bondbetween the cellulose fibers and the paper will bee brittle and look rather brown and careworn. We he all seen this in old newspapers and cheap paperback books. It has been estimated thatst paper back books will he a life of not greater than fifty years. Not what we need for our archives.F Since the lign can be reved from the paper pulp during manufacture, the obvious uestion is "why is it left in the paper?" The answer liesin the fact that lign makes up aconsiderable part of thetree. By leing the lign in the pulp a papermaker can increase his paper yield from a tree to some 95%. Reving it means a yield of only 35%. It is clearlyuneconomic to reve the lign for many paper and card applications.G It also means, of course, that lign-free paper is going to be re expensive, but that is nevertheless what the archivist must look for in his supplies. There is no int whatsoever incarefully 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 casessimply vash!H So, how do we tell a piXX of suitable paper or card from one that is unsuitable? You cannot do it by simply looking, and rather dXXpintingly,you cannot always rely on the label."Acid-free" might be true inauch as a test on the paper may indicate that it is a neutral material at this time. But lign can take years before it starts the inevitable process of breakingdown,and in the right conditions it will speed up enorusly.I Added to this, as I he indicated earlier, paper may also contain other materials added during manufacture such as bleach, china clay, chemical whiteners and size. This looks like a bleakpicture, and it would be but for thefact that there are suppliers XX will guarantee the material that they sell. If you t to be absolutely surethat you are storing in, or printing on, thecorrect material then this is probably the only way.JIncidentally, acids can migrate from material to material. Ling old shoe boxes with good uality acid-free paper will do little to guard the contents. The acid will get there in the end.Paper from RagK Paper is also nly made from cotton and rag waste. This has the advantage of being lign-free,but bXXuse there is much less cotton and rag than trees,it also tends to be much reexpensive than wood pulp paper. You will still need to purse from a reliable source though, since even rag paper and card can contain undesirable additives.L A reliable source for uality rag papers is a recogzed art stockiest. Many water colorartists insist on using only fine uality rag paper and board.M The main lesson to learn from this information is that you cannot rely on pursing archival materials from the high street. The only safe solution is to purse from specialistsuppliers. It may cost rather re, but in the end you will know that your imrtant and valuable data and images he the best home ssible.1.

以下是店铺为大家搜索整理的2017年大学英语六级阅读段落匹配真题及答案,希望能给大家带来帮助!Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage oneQuestions 46 to 50 are based on the following passage.Any veteran nicotine addict will testify that fancy packaging plays no role in the decision to keep smoking. So, it is argued, stripping cartons of their branding will trigger no mass movement to quit.But that isn’t why the government—under pressure from cancer charities, health workers and the Labour party—has agreed to legislate for standardized packaging. The theory is that smoking should be stripped of any appeal to discourage new generations from starting in the first place. Plain packaging would be another step in the reclassification of cigarettes from inviting consumer products to narcotics(麻醉剂).Naturally, the tobacco industry is violently opposed. No business likes to admit that it sells addictive poison as a lifestyle choice. That is why government has historically intervened,banning advertising, imposing health warnings and punitive (惩罚性的) duties. This approach has led over time to a fall in smoking with numbers having roughly halved since the 1970s. Evidence from Australia suggests plain packaging pushes society further along that road. Since tobacco as one of the biggest causes of premature death in the UK, a measure that tames the habit even by a fraction is worth trying.So why has it taken so long? The Department of Health declared its intention to consider the move in November 2010 and consulted through 2012. But the plan was suspended in July 2013. It did not escape notice that a lobbying firm set up by Lynton Crosby, David Cameron’s election campaign director, had previously acted for Philip Morris International. (The prime minister denied there was a connection between his news adviser’s outside interests and the change in legislative programme.) In November 2013, after an unnecessary round of additional consultation, health minister Jane Ellison said the government was minded to proceed after all. Now we are told Members of Parliament (MPs) will have a free voice before parliament is dissolved in March.Parliament has in fact already authorised the government to tame the tobacco trade. MPs voted overwhelmingly in favour of Labour amendments to the children and families bill last February that included the power to regulate for plain packaging. With sufficient will in Downing Street this would have been done already. But strength of will is the missing ingredient where Mr. Cameron and public health are concerned. His attitude to state intervention has looked confused ever since his bizarre 2006lament (叹息) that chocolate oranges placed seductively at supermarket check-outs fueled obesity.The government has moved reluctantly into a sensible public health policy, but with such obvious over-cautiousness that any political credit due belongs to the opposition. Without sustained external pressure it seems certain Mr. Cameron would still be hooked on the interests of big tobacco companies.46. What do chain smokers think of cigarette packaging?A) Fancy packaging can help to engage new smokers.B) It has little to do with the quality or taste of cigarettes.C) Plain packaging discourages non-smokers from taking up smoking.D) It has little impact on their decision whether or not to quit smoking.47. What has the UK government agreed to do concerning tobacco packaging?A) Pass a law to standardise cigarette packaging.B) Rid cigarette cartons of all advertisements.C) Subsidise companies to adopt plain packaging.D) Reclassify cigarettes according to packaging.48. What has happened in Australia where plain packaging is implemented?A) Premature death rates resulting from smoking have declined.B) The number of smokers has dropped more sharply than in the UK.C) The sales of tobacco substitutes have increased considerably.D) Cigarette sales have been falling far more quickly than in the UK.49. Why it taken so long for the UK government to consider plain packaging?A) Prime Minister Cameron has been reluctant to take action.B) There is strong opposition from veteran nicotine addicts.C) Many Members of Parliament are addicted to smoking.D) Pressure from tobacco manufacturers remains strong.50. What did Cameron say about chocolate oranges at supermarket checkouts?A) They fueled a lot of controversy.B) They made more British people obese.C) They attracted a lot of smokers.D) They had certain ingredients missing.Passage TwoQuestions 51 to 55 are based on the following passage.What a waste of money!In return for an averageof£44,000 of debt,students get an average of only 14 hours of lecture and tutorial time a week in Britain. Annual fees have risen from£1,000 to $9,000 in the last decade. But contact time at university has barely risen at all. And graduating doesn’t even provide any guarantee of a decent job:sixin ten graduates today are in non-graduate jobs.No wonder it has become fashionable to denounce many universities as little more that elaboratecom-tricks(骗术). There’s a lotfor students to complain about the repayment threshold for paying back loans will be frozen for five years, meaning that lower-paid graduals have to start repaying their loans, and maintenance grants have been replaced by loans meaning that students from poorer backgrounds face higher debt than those with wealthier parents.Yet it still pays to go to university. If going to university doesn’t work out, students pay very little—if any—of their tuition fees back, you only start repaying when you are earning£21, 000 a year. Almost half of graduates—those who go on to earn less—will have a portion of their debt written off. It’s not just the lectures and tutorials that are important. Education is the sum of what students teach each other in between lectures and seminars. Students do not merely benefit while at university, studies show they go on to be healthier and happier than non-graduates, and also far more likely to vote.Whatever your talents, it is extraordinarily difficult to get a leading job in most fields without having been to university. Recruiters circle elite universities like vulturous(兀鹰). Many top firms will not even look at applications from those who lack a 2.1, i.e., an upper-second class degree, from an elite university. Students at university also meet those likely to be in leading jobs in the future, forming contacts for life. This might not be right, but school-leavers who fail to acknowledge as much risk making the wrong decision about going to university.Perhaps the reason why so many universities offer their students so little is they know studying at a top university remains a brilliant investment even if you don’t learn anything .Studying at university will only become less attractive if employers shift their focus away from where someone went to university—and there is no sign of that happening anytime soon. School-leavers may moan, but they have little choice but to embrace university and the student debt that comes with it.51. What is the author’s opinion of going to university?A) It is worthwhile after all.B) It is simply a waste of time.C) It is hard to say whether it is good or bad.D) It is too expensive for most young people.52. What does the author say about the employmentsituation of British university graduates?A) Few of them are satisfied with the jobs they are offered.B) It usually takes a long time for them to find a decent job.C) Graduates from elite universities usually can get decent jobs.D) Most of them take jobs which don’t require a college degree.53. What does the author say is important for university students besides classroom instruction?A) Making sure to obtain an upper-second class degree.B) Practical skills they will need in their future careers.C) Interactions among themselves outside the classroom.D) Developing independent and creative thinking abilities.54. What is said to be an advantage of going to university?A) Learning how to take risks in an ever-changing world.B) Meeting people who will be helpful to you in the future.C) Having opportunities of playing a leading role in society.D) Gaining up-to-date knowledge in science and technology.55. What can we infer from the last paragraph?A) It is natural for students to make complaints about university education.B) Few students are willing to bear the burden of debt incurred at university.C) University education is becoming attractive to students who can afford it.D) The prestige of the university influences employers’ recruitment decisions.Section Cpassage one46.

六级阅读-段落匹配
Waste Not, Want NotFeeding the 9 Billion: The Tragedy of Waste[A] By 2075, the United Nations' mid-range projection for global population is about 9.5 billion. This means thatthere could be an extra three billion mouths to feed by the end of the century, a period in which substantial changes are anticipated in the wealth, calorie intake and dietary preferences of people in developing countries across the world. Such a projection presents mankind with wide-ranging social, economic, environmental and political issues that need to be addressed today to ensure a sustainable future for all. One key issue is how to produce more food in a world of finite resources.[B] Today, we produce about four billion metric tonnes of food per year. Yet due to poor practices in harvesting,storage and transportation, as well as market and consumer wastage, it is estimated that 30-50% of all food produced never reaches a human stomach. Furthermore, this figure does not reflect the fact that large amounts of land, energy, fertilisers and water have also been lost in the production of foodstuffs which simply end up as waste. This level of wastage is a tragedy that cannot continue if we are to succeed in the challenge of sustainably meeting our future food demands. |Where Food Waste Happens[C] In 2010,the Institution of Mechanical Engineers identified three principal emerging population groups acrossthe world, based on characteristics associated with their current and projected stage of economic development.• Fully developed, m ature, post-industrial societies, such as those in Europe, characterised by stable or declining populations which are increasing in age.• Late-stage developing nations that are currently industrialising rapidly, for example China, which will experience declining rates of population growth, coupled with increasing affluence (富裕)and age profile.• Newly developing countries that are beginning to industrialise, primarily in Africa, with high to very high population growth rates, and characterised by a predominantly young age profile.[D] Each group over the coming decades will need to address different issues surrounding food production, storageand transportation, as well as consumer expectations, if we are to continue to feed all our people.[E] In less-developed countries, such as those of sub-Saharan Africa and South-East Asia, wastage tends to occurprimarily at the farmer-producer end of the supply chain. Inefficient harvesting, inadequate local transportation and poor infrastructure (基础设施)mean that produce is frequently handled inappropriately and stored under unsuitable farm site conditions.[F] In mature, fully developed countries such as the UK, more-efficient farming practices and better transport,storage and processing facilities ensure that a larger proportion of the food produced reaches markets and consumers. However, characteristics associated with modern consumer culture mean produce is often wasted through retail and customer behaviour.[G] Major supermarkets, in meeting consumer expectations, will often reject entire crops of perfectly edible fruitand vegetables at the farm because they do not meet exacting marketing standards for their physical characteristics, such as size and appearance.[H] Of the produce that does appear in the supermarket, commonly used sales promotions frequently encouragecustomers to purchase excessive quantities which, in the case of perishable foodstuffs, inevitably generate wastage in the home. Overall between 30% and 50% of what has been bought in developed countries is thrown away by the purchaser.Better Use of Our Finite Resources[I] Wasting food means losing not only life-supporting nutrition but also precious resources, including land, waterand energy. As a global society, therefore, tackling food waste will help contribute towards addressing a number of key resource issues.[J] Land Usage: Over the last five decades, improved farming techniques and technologies have helped to significantly increase crop yields along with a 12% expansion of farmed land use. However, a further increase in farming area without impacting unfavourably on what remains of the world's natural ecosystems appears unlikely. The challenge is that an increase in animal-based production will require more land and resources, as livestock (牲畜)farming demands extensive land use.[K] Water Usage: Over the past century, human use of fresh water has increased at more than double the rate of population growth. Currently about 3.8 trillion m3of water is used by humans per year. About 70% of this is consumed by the global agriculture sector, and the level of use will continue to rise over the coming decades. [L] Better irrigation can dramatically improve crop yield and about 40% of the world's food supply is currently derived from irrigated land. However, water used in irrigation is often sourcedunsustainably.In processing foods after the agricultural stage, there are large additional uses of water that need to be tackled in a world of growing demand. This is particularly crucial inthe case of meat production, where beef uses about 50 times more water than vegetables. In the future, more effective washing techniques, management procedures, and recycling and purification of water will be needed to reduce wastage.[M]Energy Usage: Energy is an essential resource across the entire food production cycle, with estimates showing an average of 7-10 calories of input being required in the production of one calorie of food. This varies dramatically depending on crop, from three calories for plant crops to 35 calories in the production of beef.Since much of this energy comes from the utilisation of fossil fuels, wastage of food potentially contributes to unnecessary global warming as well as inefficient resource utilisation.[N] In the modem industrialised agricultural process—which developing nations are movingtowards in order to increase future yields—energy usage in the making and application of fertilisersand pesticides represents the single biggest component. Wheat production takes 50% of its energy input for these two items alone. Indeed, on a global scale, fertilisermanufacturing consumes about 3-5% of the world's annual natural gas supply. With production anticipated to increase by 25% between now and 2030, sustainable energy sourcing will become an increasingly major issue. Energy to power machinery, both on the farm and in the storage and processing facilities, adds to the energy total, which currently represents about 3.1% of annual global energy consumption.Recommendations[O] Rising population combined with improved nutrition standards and shifting dietary preferences will exert pressure for increases in global food supply. Engineers, scientists and agriculturalists have the knowledge, tools and systems that will assist in achieving productivity increases. However, pressure will grow on finite resources of land, energy and water. The potential to provide 60-100% more food by simply eliminating losses, while simultaneously freeing up land, energy and water resources for other uses, is an opportunity that should not be ignored. In order to begin tackling the challenge, the Institution recommends that:•The UN Food and Agriculture Organisation work with the international engineering community to ensure governments of developed nations put in place programmes that transferengineering knowledge, design know-how, and suitable technology to newly developing countries. This will help improve produce handling in the harvest, and immediate post-harvest stages of food production.•Governments of rapidly developing countries incorporate waste minimisation thinking into the transport infrastructure and storage facilities currently being planned, engineered and built.• Governments in developed nations devise and implement policy that changes consum er expectations. These should discourage retailers from wasteful practices that lead to the rejection of food on the basis of cosmetic characteristics, and losses in the home due to excessive purchasing by consumers.46. Elimination of waste alone can potentially provide over sixty percent more food for the growing worldpopulation.47. The production and application of fertilisers and pesticides account for the largest part of energy use in themodernindustrialised agricultural process.48. Consumers in developed countries throw away nearly half of their food purchases because they tend to buy inexcessive quantities.49. It is recommended that engineering knowledge and suitable technology in developed countries be introduced todeveloping countries to improve produce handling in the harvest.50. The predicted global population growth means that ways have to be found to produce more food with finiteresources.51. A further expansion of farming area will adversely impact on the world's natural ecosystems.52. Perfectly eatable fruit and vegetable crops often fail to reach supermarkets due to their size or physicalappearance.53. Poor practices in harvesting, storage and transportation have resulted in a waste of much of the food we produceand thus a waste of land and resources.54. Food waste in less-developed countries happens mainly at the producers' end.55. Beef consumes far more water to produce than vegetables.。
2021年12月英语六级阅读真题及答案 第2套 段落匹配_3
2021年12月英语六级阅读真题及答案第2套段落匹配A Pioneering Woman of Science Re-Emerges after 300 YearsA) Maria Sibylla Merian, like many European women of the 17th century, stayed busy managing a household and rearing children. But on top of that, Merian, a German-born woman who lived in the Netherlands, also managed a successful career as an artist, botanist, naturalist and entomologist (昆虫学家).B) "She was a scientist on the level with a lot of people we spend a lot of time talking about," said Kay Etheridge, a biologist at Gettysburg College in Pennsylvania who has been studying the scientific history of Merian's work. "She didn't do as much to change biology as Charles Darwin, but she was significant. "C) At a time when natural history was a valuable tool for discovery, Merian discovered facts about plants and insects that were not previously known. Her observations helped dismiss the popular belief that insects spontaneously emerged from mud. The knowledge she collected over decades didn't just satisfy those curious about nature, but also provided valuable insights into medicine and science. She was the first to bring togetherinsects and their habitats, including food they ate, into a single ecological composition.D) After years of pleasing a fascinated audience across Europe with books of detailed descriptions and life-size paintings of familiar insects, in 1699 she sailed with her daughter nearly 5, 000 miles from the Netherlands to South America to study insects in the jungles of what is now known as Suriname. She was 52 years old. The result was her masterpiece, Metamorphosis Insectorum Surinamensium.E) In her work, she revealed a side of nature so exotic, dramatic and valuable to Europeans of the time that she received much acclaim. But a century later, her findings came under scientific criticism. Shoddy(粗糙的)reproductions of her work along with setbacks to women's roles in 18th- and 19th- century Europe resulted in her efforts being largely forgotten. "It was kind of stunning when she sort of dropped off into oblivion (遗忘)," said Dr. Etheridge. "Victorians started putting women in a box, and they're still trying to crawl out of it."F) Today, the pioneering woman of the sciences has re-emerged. In recent years, feminists,historians and artists have all praised Merian's tenacity(坚韧), talent and inspirational artistic compositions. And now biologists likeDr. Etheridge are digging into the scientific texts that accompanied her art. Three hundred years after her death, Merian will be celebrated at an international symposium in Amsterdam this June.G) And last month, Metamorphosis Insectorum Surinamensium was republished. It contains 60 plates (插图)and original descriptions, along with stories about Merian's life and updated scientific descriptions. Before writing Metamorphosis, Merian spent decades documenting European plants and insects that she published in a series of books. She began in her 20s, making textless, decorative paintings of flowers with insects. "Then she got really serious," Dr. Etheridge said. Merian started raising insects at home, mostly butterflies and caterpillars. "She would sit up all night until they came out of the pupa (桶)so she could draw them," she said.H) The results of her decades' worth of careful observations were detailed paintings and descriptions of European insects, followed by unconventional visuals and stories of insects and animals from a land that most at the time could only imagine. It's possible Merian used a magnifying glass to capture the detail of the split tongues of sphinx moths (斯芬克斯飞蛾)depicted in the painting. She wrote that the twotongues combine to form one tube for drinking nectar (花蜜). Some criticized this detail later, saying there was just one tongue, but Merian wasn't wrong. She may have observed the adult moth just as it emerged from its pupa. For a brief moment during that stage of its life cycle, the tongue consists of two tiny half-tubes before merging into one.I) It may not have been ladylike to depict a giant spider devouring a hummingbird, but when Merian did it at the turn of the 18th century, surprisingly, nobody objected. Dr. Etheridge called it revolutionary. The image, which also contained novel descriptions of ants, fascinated a European audience that was more concerned with the exotic story unfolding before them than the gender of the person who painted it.J) "All of these things shook up their nice, neat little view," Dr. Etheridge said. But later, people of the Victorian era thought differently. Her work had been reproduced, sometimes incorrectly. A few observations were deemed impossible. "She'd been called a silly woman for saying that a spider could eat a bird," Dr. Etheridge said. But Henry Walter Bates, a friend of Charles Darwin, observed it and put it in book in 1863, proving Merian was correct.K) In the same plate, Merian depicted and describedleaf-cutter ants for the first time. "In America there are large ants which can eat whole trees bare as a broom handle in a single night, she wrote in the description. Merian noted how the ants took the leaves below ground to their young. And she wouldn't have known this at the time, but the ants use the leaves to farm fungi (菌类)underground to feed their developing babies.L) Merian was correct about the giant bird-eating spiders, ants building bridges with their bodies and other details. But in the same drawing, she incorrectly lumped together army and leaf-cutter ants. And instead of showing just the typical pair of eggs in a hummingbird nest, she painted four. She made other mistakes in Metamorphosis Insectorum Surinamensium as well: not every caterpillar and butterfly matched.M) Perhaps one explanation for her mistakes is that she cut short her Suriname trip after getting sick, and completed the book at home in Amsterdam. And errors are common among some of history's most- celebrated scientific minds, too. "These errors no more invalidate Ms. Merian's work than do well- known misconceptions published by Charles Darwin or Isaac Newton, " Dr. Etheridge wrote in a paper that argued that too many have wrongly focused on the mistakes of her work.N) Merian's paintings inspired artists and ecologists. Inan 1801 drawing from his book, General Zoology Amphibia, George Shaw, an English botanist and zoologist, credited Merian for describing a frog in the account of her South American expedition, and named the young tree frog after her in his portrayal of it. It wouldn't be fair to give Merian all the credit. She received assistance naming plants, making sketches and referencing the work of others. Her daughters helped her color her drawings.O) Merian also made note of the help she received from the natives of Suriname, as well as slaves or servants that assisted her. In some instances she wrote moving passages that included her helpers in descriptions. As she wrote in her description of the peacock flower, "The Indians, who are not treated well by their Dutch masters, use the seeds to abort their children, so that they will not become slaves like themselves. The black slaves from Guinea and Angola have demanded to be well treated, threatening to refuse to have children. In fact, they sometimes take their own lives because they are treated so badly, and because they believe they will be born again, free and living in their own land. They told me this themselves. "P) Londa Schiebinger, a professor of the history of science at Stanford University, called this passage rather astonishing.It's particularly striking centuries later when these issues are still prominent in public discussions about social justice and women's rights. "She was ahead of her time," Dr. Etheridge said.36. Merian was the first scientist to study a type of American ant.37. The European audience was more interested in Merian's drawings than her gender.38. Merian's masterpiece came under attack a century after its publication.39. Merian's mistakes in her drawings may be attributed to her shortened stay in South America.40. Merian often sat up the whole night through to observe and draw insects.41. Merian acknowledged the help she got from natives of South America.42. Merian contributed greatly to people's better understanding of medicine and science.43. Merian occasionally made mistakes in her drawings of insects and birds.44. Now, Merian's role as a female forerunner in sciences has been re-established.45. Merian made a long voyage to South America to study jungle insects over three centuries ago.36.K37.I38.E39.M40.G41.O42.C43.L44.F45.D。
大学英语六级阅读理解练习和参考答案
大学英语六级阅读理解练习和参考答案大学英语六级阅读理解练习和参考答案:Once youre prepared for a situation, youre 50 percent of the way toward overcoming nervousness. The other 50 percent is the physical and mental control of nervousness; adjusting your attitude so you have confidence, and control of yourself and your audience.I was in the theater for many years and always went to work with terrible stage fright—until I was in "The King and I". While waiting offstage one night, I saw Yul Brynner, the shows star, pushing in a lunging position against a wall. It looked as though he wanted to knock it down. "This helps me control my nervousness," he explained.I tried it and, sure enough, freed myself from stage fright. Not only that, but pushing the wall seemed to give me a whole new kind of physical energy. Later I discovered that when you push against a wall you contract the muscles that lie just below where your ribs begin to splay (展开).I call this area the "vital triangle".To understand how these muscles work, try this: sit in astraight-backed chair and lean slightly forward. Put your palms together in front of you, your elbows pointing out the sides, your fingertips pointing upward, and push so that you feel pressure in the heels of your palms and under your arms.Say ssssssss, like a hiss. As youre exhaling the s, contract those muscles in the vital triangle as though you were rowing a boat, pulling the oars back and up. The vital triangle should tighten. Relax the muscles at the end of your exhalation, then inhale gently.You can also adjust your attitude to prevent nervousness. What you say to yourself sends a message to your audience. If you tell yourself youre afraid, thats the message your listener receives. So select the attitude you want to communicate. Attitude adjusting is your mental suit of armor against nervousness. If you entertain only positive thoughts, you will be giving out these words: joy and ease, enthusiasm, sincerity and concern, and authority.21. To overcome nervousness, one should_______.A. adjust his attitude as well as make preparation for a gatheringB. ask the audience to give him confidenceC. try not to be knocked down by stage frightD. wait offstage22. "The King and I" should be_______.A. a filmB. a novelC. a playD. a song23. The writer cites examples in Paragraphs 4 and 5 to support his statement that_______.A. you will have a positive effect by putting energy into your voiceB. youre 50 percent of the way towards overcoming nervousness once you are prepared for a situationC. you will have a whole new kind of physical energy by pushing against a wallD. if you master the techniques informed by the author your will never be nervous again24. Yul Brynner pushed the wall in order to_______.A. show the writer how to overcome nervousnessB. pull down the wallC. get physical energyD. overcome his own nervousness25. If you have active thoughts, your audience will detect ______.A. that you are full of fear and depressionB. that you are tightening your vital triangleC. that you are joyful and easy-goingD. that you are relaxing your muscles21.

One night after a match, he was offered a whisky bottle on the ride home. Tod felt he had to accept,or he would seem like a sissy. He took a swallow, and every time the bottle was passed back to him, he took another swallow. After seven swallows, he passed out. His terrified teammates carried him into his home, and his mother then rushed to the hospital. After his stomach was pumped, Tod learned that his blood alcohol level had been so high that he was lucky not to be in a coma or dead.Although alcohol sometimes causes rapid poisoning, frequently leads to long-term addiction, and always threatens self-control, our society encourages drinking. Many parents, by their example, give children the impression that alcohol is an essential ingredient of social gatherings. Peer pressure turns bachelor parties, fraternity initiations (同仁联谊会入会) , and spring-semester beach vacations into competitions in "getting trashed. " In soap operas, charming characters pour Scotch whiskey from crystal bottle as readily as most people turn on the faucet for tap water. In films and rock videos, trend-setters party in nightclubs and bars. And who can recall a televised baseball or basketball game without a beer commercial? By the age of 21, the average American has been drinking on TV about 75, 000 times. Alcohol ads appear with pounding frequency—in magazines, on billboards, in college newspapers—contributing to a harmful myth about drinking.Part of the myth is that liquor signals professional success. In a mens magazine, one full-page ad for Scotch whiskey shows two men seated in an elegant restaurant. Both are in their thirties, perfectly groomed, and wearing expensive grey suits. The windowsare draped (悬挂) with velvet (天鹅绒) the table with spotless white linen. Each place-setting consists of a long-stemmed water goblet, silver utensils and thick silver plates. On each plate is half-empty cocktail glass. The two men are grinning andshaking hands, as if theyve just concluded a business deal. The caption reads, "The taste of success. "Contrary to what the liquor company would have us believe, drinking is more closely related to lack of success than to achievement. Among students, the heaviest drinkers have the lowest grades. In the work force, alcoholics are frequently late or absent, tend to perform poorly, and often get fired. Although, alcohol abuse occurs in all economic classes, it remains most severe among the poor.Another part of the alcohol myth is that drinking makes you more attractive to the opposite sex. "Hot, hot, hot," one commercials soundtrack(电影配乐) begins, as the camera scans a crowd of college-age beachgoers. Next it follows the curve of a womans leg up to her bare hip and lingers there. She is young, beautiful, wearing a bikini. A young guy, carrying an ice chest (箱子), positions himself near to where she sits. He is tan, muscular. She doesnt show much interest—until he opens the chest and takes out a beer. Now she smiles over at him. He raises his eyebrows and, invitingly, holds up another can. She joins him. This beer, the song concludes, "attracts like no other. "Beer doesnt make anyone sexier. Like all alcohol, it lowers the levels of male hormones in men and of female hormones in women—even when taken in small amounts. In substantial amounts, alcohol can causeinfertility(不生育) in women and impotence (阳萎|) in men. Some alcoholic men develop enlarged breasts, from their increased female hormones.The alcohol myth also creates the illusion that beer and athletics are a perfect combination. One billboard features three high-action images: a baseball player running at top speed, a surfer riding a wave,and a basketball player leaping to make a dunk shot. A particular light beer, the billboard promises, "wont slow you down. "。

大学英语CET6阅读精选试题及答案According to the latest research in the United States of America, men and women talk such different languages that it is like people from two different cultures trying to municate、Professor Deborah Tannen of Georgetown University, has noticed the difference in the style of boys and girls conversations from an early age、She says that little girls conversation is less definite than boys and expresses more doubts、Little boys use conversation to establish status with their listeners.These differences continue into adult life, she says、In public conversations, men talk most and interrupt other speakers more、In private conversations, men and women speak in equal amounts—although they say things in a different style、Professor Tannen believes that, for woman, private talking is a way to establish and test intimacy、For men, private talking is a way to explore the power structure of a relationship.Teaching is one job where the differences between mens and womens ways of talking show、When a man teaches a woman, says Professor Tannen, he wants to show that he has more knowledge, and hence more power in conversation、When a woman teaches another woman, however, she is more likely to take a sharing approach and to encourage her student to join in、But Professor Tannen does not believe that women are naturally more helpful、She says women feel they achieve power by being able to help others、Although the research suggests men talk and interrupt people more than women, Professor Tannen says, women actually encourage this to happen because they believe it will lead to more intimacy and help to establish a relationship.Some scientists who are studying speech think that the brain is preprogrammed for language、As we are usually taught to speak by women, it seems likely that the brain must have a sexual bias(倾向性) in its programming,otherwise male speech patterns would not arise at all.1、In the opinion of the writer, women encourage men to talk becauseA、it will lead to more intimacy and help to establish a relationshipB、it will help to establish status with their listenersC、it will help to express more clearlyD、it will help to municate better2、There are_______in little girls conversation than in boys.A、fewer doubtsB、more demandsC、more doubtsD、fewer uncertainties3、Some scientists believe that brain is pre-programmed for language、The word "pre programmed" means_______.A、programmed alreadyB、programmed before one is bornC、programmed earlyD、programmed by women4、In private conversation, women speakA、the same things as menB、less than menC、more than menD、as much as men5、The theme of this article is _______.A、women are naturally more helpfulB、men and women talk different languagesC、men talk most and interrupt other speakers moreD、little girls conversation is less definite参考答案:1、A 2、C 3、B 4、D 5、B试题及答案Women are also underrepresented in the administration and this is because there are so few women full professors、In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging University was rated among the lowest for the a 1987 ,Milburn mended the progress that was made and called for even more improvement、One of the positive results from her study was a System-wide program to inform women of available administrative jobs、College of munication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it esto relocating if they want to rise in the ranks、Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work、Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist、"Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said、"If they do that will be successful in this they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1、According to Spirduso,women need to ____a report on sexual discriminationfor further improvement in their working conditionstheir energies and time fighting against sexual discriminationmore time and energy doing scholarly activities2、From this passage ,we know that _____.are many women full professors in the University of Texasplay an important part in adminitrating the Universityweather on the campus is chillymake up a small percentage of the senior positions in the University3、Which of the following statements is true?number of women professors in the University in 1987 was greater than that of 1985number of women professors in the University in 1987 was smaller than that of 1985number of women professors was the same as that of 1985and more women professors thought that sexual discrimination did exit in the University4、One of the positive results from Milburns study was that _____were told to con centrate on teir workwere given information about available administrative jobswere encouraged to take on all the administrative jobs in the Unversity were encouraged to do more scholarly activities5、The title for this passage should be _______.University of TexasReportProfessorsDiscrimination in Academia答案:1、d,2、d,3、a,4、b,5、d。
2021年6月英语六级阅读真题及答案 第2套 段落匹配
2021年6月英语六级阅读真题及答案第2套段落匹配Companies Are Working with Consumers to Reduce WasteA) As consumers, we are very wasteful. Annually, the world generates 1.3 billion tons of solid waste. This is expected to go up to 2.2 billion by 2025. The developed countries are responsible for 44% of waste, and in the U. S. alone, the average person throws away their body weight in rubbish every month.B) Conventional wisdom would seem to suggest that companies have no incentive to lengthen the life cycle of their products and reduce the revenue they would get from selling new goods. Yet, more and more businesses are thinking about how to reduce consumer waste. This is partly driven by the rising price of raw materials and metals. It is also partly due to both consumers and companies becoming more aware of the need to protect our environment.C) When choosing what products to buy and which brands to buy from, more and more consumers are looking into sustainability. This is opposed to just price and performance they were concerned about in the past. In a survey of 54 of the world's leading brands, almost all of them reported thatconsumers are showing increasing care about sustainable lifestyles. At the same time, surveys on consumers in the U.S. and the U. K. show that they also care about minimizing energy use and reducing waste.D) For the most part, consumers control what happens to a product. But some companies are realizing that placing the burden of recycling entirely on the consumer is not an effective strategy, especially when tossing something away seems like the easiest and most convenient option.E) Some retailers and manufacturers in the clothing, footwear, and electronics industries have launched environmental programs. . They want to make their customers interested in preserving their products and preventing things that still have value from going to the garbage dump. By offering services to help expand the longevity of their products, they're promising quality and durability to consumers, and receiving the reputational gains for being environmentally friendly.F) For example, the Swedish jeans company Nudie Jeans offers free repair at twenty of their shops. Instead of discarding their old worn-out jeans, customers bring them in to be renewed. The company even provides mail-order repair kitsand online videos, so that customers can learn how to fix a pair of jeans at home. Their philosophy is that extending the life of a pair of jeans is not only great for the environment, but allows the consumer to get more value out of their product. When customers do want to toss their pair, they can give them back to the store ,which will repurpose and resell them. Another clothing company, Patagonia, a high-end outdoor clothing store, follows the same principle. It has partnered with DIY website iFixit to teach consumers how to repair their clothing, such as waterproof outerwear,' at home. The company also offers a repair program for their customers for a modest fee. Currently, Patagonia repairs about 40,000 garments a year in their Reno, Nevada, service center. According to the company's CEO, Rose Marcario, this is about building a company that cares about the environment. At the same time, offering repair supports the perceived quality of its products.G) In Brazil, the multinational corporation Adidas has been running a shoe-recycling program called “Sustainable Footprint” since 2021. Customers can bring shoes of any brand into an Adidas store to be shredded and turned into alternative fuels for energy creation instead of being burned as trash, They are used to fuel cement ovens. To motivate visitors to bringin more old shoes, Adidas Brazil promotes the program in stores by showing videos to educate customers, and it even offers a discount each time a customer brings in an old pair of shoes. This boosts the reputation and image of Adidas by making people more aware of the company's values.H) Enormous opportunities also lie with e-waste. It is estimated that in 2021 the world produced some 42 million metric tons of e-waste (discarded electrical and electronic equipment and its parts) with North America and Europe accounting for 8 and 12 million metric tons respectively. The materials from e-waste include iron, copper, gold, silver, and aluminum- materials that could be reused, resold, salvaged, or recycled. Together, the value of these metals is estimated to be about $ 52 billion. Electronics giants like Best Buy and Samsung have provided e-waste take-back programs over the past few years, which aim to refurbish (翻新) old electronic components and parts into new products.I) For other companies interested in reducing waste, helping the environment, and providing the sustainable lifestyles that consumers seek, here are some first steps for building a relationship with customers that focuses on recycling and restoring value to products :J) Find partners. If you are a manufacturer who relies on outside distributors, then retailers are the ideal partner for collecting old products. Power tool maker DeWalt partners with companies, such as Lowes and Napa Auto Parts, to collect old tools at their stores for recycling. The partnership benefits both sides by allowing unconventional partners (for example, two companies from two different industries) to work together on a specific aspect of the value chain, like, in this example, an engine firm with an accessory one.K) Create incentives. Environmental conscientiousness isn't always enough to make customers recycle old goods. For instance, DeWalt discovered that many contractors were holding on to their old tools , even f they no longer worked, because they were expensive purchases and it was hard to justify bringing them in to recycle. By offering instant discounts worth as much as $ 100, DeWalt launched a trade-in program to encourage people to bring back tools. As a result, DeWalt now reuses those materials to create new products.L) Start with a trial program, and expect to change the details as you go. Any take-back program will likely change over time, depending on what works for your customers and company goals. Maybe you see low customer participation at first, orconversely, so much success that the cost of recycling becomes too high. Best Buy, for instance, has been bearing the lion's share of e-waste volume since two of its largest competitors, Amazon and Wal-mart, do not have their own recycling programs. Since the launch of its program, Best Buy changed its policy to add a $ 25 fee for recycling old televisions in order to keep the program going.M) Build a culture of collective values with customers. A stronger relationship between the retailer/producer and the consumer isn't just about financial incentives. By creating more awareness around your efforts to reduce waste, and by developing a culture of responsibility, repair, and reuse, you can build customer loyalty based on shared values and responsibilities.N) These examples are just the tip of the iceberg, but they demonstrate how helping customers get more use of their materials can transform value chains and operations. Reducing waste by incorporating used materials into production can cut costs and decrease the price of procurement (采购): less to be procured from the outside and more to be re-utilized from the inside.O) Companies play a big role in creating a circular economy,in which value is generating less from extracting new resources and more from getting better use out of the resources we already have——but they must also get customers engaged in the process.36. Some companies believe that products' prolonged lifespan benefits both the environment and customers.37. A survey shows shoppers today are getting more concerned about energy conservation and environmental protection when deciding what to buy.38. Companies can build customer loyalty by creating a positive culture of environmental awareness.39. When companies launch environmental programs, they will have their brand reputation enhanced.40. One multinational company offers discounts to customers who bring in old footwear to be used as fuel.41. Recycling used products can help manufacturers reduce production costs.42. Electronic products contain valuable metals that could be recovered.43. It seems commonly believed that companies are not motivated to prolong their products' ifespan.44. It is advisable for companies to partner with each other in product recycling.45. Some businesses have begun to realize it may not be effective to let consumers take full responsibility for recycling.36.F37.C38.M39.E40.G41.N42.H43.B44.J45.D。
六级段落匹配练习题带答案
六级段落匹配练习题带答案六级段落匹配练习题:A. Benjamin Franklin--of "early to bed and early to rise" fame--was apparently the first person to suggest the concept of daylight savings. While serving as U.S. ambassador to France in Pads,Franklin wrote of being awakened at 6 a.m. and realizing, to his surprise, that the sun would rise far earlier than he usually did. Imagine the resources that might be saved if he and othersrose before noon and burned less midnight oil, Franklin, tongue half in cheek, wrote to a newspaper.B. It wasn't until World War I that daylight savings were realized on a grand scale. Germany was the first state to adopt the time changes, to reduce artificial lighting and thereby save coalfor the war effort. Friends and foes soon followed suit. In the U.S. a federal law standardized the yearly start and end of daylight saving time in 1918--for the states that chose to observeit.C. During World War II the U.S. made daylight saving time mandatory强制的for the whole country, as a way to save wartime resources. Between February 9, 1942, and September 30, 1945, thegovernment took it a step further. During this period daylight saving time was observed year-round, essentially making it the new standard time, if only for a few years. Many years later, theEnergy Policy Act of 2021 was enacted, mandating a controversial month-long extension of daylight saving time, starting in 2021.Daylight Saving Time: Energy Saver or Just Time Sucker?D. In recent years several studies have suggested that daylight saving time doesn't actually save energy--and might even result in a net loss. Environmental economist Hendrik Wolff, of theUniversity of Washington, co- authored a paper that studied Australian power-use data when parts of the country extended daylight saving time for the 2000 Sydney Olympics and others did not.The researchers found that the practice reduced lighting and electricity consumption in the evening but increased energy use in the now dark mornings-- wiping out the evening gains. That'sbecause the extra hour that daylight saving time adds in the evening isa hotter hour. "So if people get home an hour earlier in a wanner house, they turn on their air conditioning," theUniversity of Washington's Wolff said.E. But other studies do show energy gains. In an October 2021 daylight saving time report to Congress, mandated by the same 2021 energy act that extended daylight saving time, the U.S.Department of Energy asserted that springing forward does save energy. Extended daylight saving time saved 1.3 terawatt 太瓦 hours of electricity. That figure suggests that daylight savingtime reduces annual U.S. electricity consumption by 0.03 percent and overall energy consumption by 0.02 percent. While those percentages seem small, they could represent significant savingsbecause of the nation's enormous total energy use.F. What's more, savings in some regions are apparently greater than in others. California, for instance, appears to benefit most from daylight saving time--perhaps because its relatively mildweather encourages people to stay outdoors later. The Energy Department report found that daylight saving time resulted in an energy savings of one percent daily in the state.G. But Wolff, one of many scholars who contributed to the federal report, suggested that the numbers were subject to statistical variability 变化 and shouldn't be taken as hard facts. Anddaylight savings' energy gains in the U.S. largely depend on yourlocation in relation to the Mason-Dixon Line, Wolff said."The North might be a slight winner, because the North doesn't have asmuch air conditioning," he said. "But the South is a definite loser in terms of energy consumption. The South has more energy consumption under daylight saving."Daylight Saving Time: Healthy or Harmful?H. For decades advocates of daylight savings have argued that, energy savings or no, daylight saving time boosts health by encouraging active lifestyles--a claim Wolff and colleagues arecurrently putting to the test. "In a nationwide American time-use study, we're clearly seeing that, at the time of daylight saving time extension inthe spring, television watching issubstantially reduced and outdoor behaviors like jogging, walking, orgoing to the park are substantially increased," Wolff said. "That's remarkable, because of course the total amount ofdaylight in a given day is the same. "I. But others warn of ill effects. Till Roenneberg, a university professor in Munich 慕尼黑, Germany, said his studies show that our circadian 生理节奏的body clocks--set by light anddarkness--never adjust to gaining an "extra" hour of sunlight to the end of the day during daylight saving time.J. One reason so many people in the developed world are chronically 长期地overtired, he said, is that they suffer from"social jet lag. "In other words, their optimal circadian sleep periodsdon't accord with their actual sleep schedules. Shifting daylight from morning to evening only increases this lag, he said. "Light doesn't do the same things to the body in the morning and theevening. More light in the morning would advance the body clock, andthat would be good. But more light in the evening would even further delay the body clock. "K. Other research hints at even more serious health risks. A 2021 study concluded that, at least in Sweden, heart attack risks go up in the days just after the spring time change. "The mostlikely explanation to our findings is disturbed sleep and disruption of biological rhythms," One expert told National Geographic News via email.Daylight Savings' Lovers and HatersL. With verdicts 定论 on the benefits, or costs, of daylight savings so split, it may be no surprise that the yearly time changes inspire polarized reactions. In the U.K., for instance, theLighter Later movement--part of 10:10,a group advocating cutting carbon emissions--argues for a sort of extreme daylight savings. First, they say,move standard time forward an hour, then keepobserving daylight saving time as usual--adding two hours ofevening daylight to what we currently consider standard time. The folks behind Standardtime, on the other hand, want to abolishdaylight saving time altogether, calling energy-efficiency claims "unproven. "M. National telephone surveys by Rasmussen Reports from spring 2021 and fall 2021 deliver the same answer.Most people just "don't think the time change is worth the hassle 麻烦的事 . "Forty-seven percent agreedwith that statement, while only 40 percent disagreed. But Seize the Daylight author David Prerau said his research on daylight saving time suggests most people arefond of it."I think if you ask most people if they enjoy having an extra hour of daylight in the evening eight months a year, the response would be pretty positive."段落匹配练习题选项:46. Daylight savings' energy gains might be various due to different climates.47. Disturbed sleep and disruption of biological rhythms may be the best explanation to higher heart attack risks in the days after the spring time change.48. A research indicated that DST might not save energy by increasing energy use in the dark mornings, though it reduced lighting and electricity consumption in the evening.49. Germany took the lead in saving wardme resources by adopting the time changes and reducing artificiallighting.50. A university professor studied the effect of daylight saving time and sounded the alarm of its negative effects.51. Social jet lag can partly account for people's chronic fatigue syndrome in developed countries.52. The figure of a study in the U.S. suggested that DST could save a lot of energy nationally.53. Supporters of daylight savings have long considered daylight saving time does good to people's health.54. A group advocating cutting carbon emissions launches the Lighter Later movement to back a kind of extreme daylight savings.55. A scholar contributing to a federal report suggested that the amount of saved energy had something to do with geographic position.段落匹配练习题答案:46.F解析:题干意为,夏令时带来的能源收益可能会因为不同的气候而有差异。

英语六级阅读段落匹配练习题及答案英语六级阅读段落匹配练习题原文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 other for the text. Choose two fonts that visually contrast with each other. Garamond Medium Condensed and Impactare 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.Dont 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. Dont 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, clickSave 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 youre done, PowerPoint automatically closes and you return to the desktop. If you want to edit the slide show file, you can always open it from PowerPoint by clicking Open on the File menu.L) Look at the audience, not at the slides, whenever possible. If using a laser pointer, dont 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 youve 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.英语六级阅读段落匹配练习题目1. The ways in which academic and business presentations are made have been changed by Microsoft PowerPoint.2. When making the PowerPoint, the wording of the text should not be complicated.3. In each slide, the font styles for the title and the text should contrast with each other.4.

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 to plant 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 of 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 vonBellingshausen, a high-ranking officer in the Imperial Russian Navy who explored the Antarctic coast in 1820.G) Antarcticas mineral, oil and gas wealth are a longer-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 on King 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.

英语六级段落匹配题及答案英语六级段落匹配题原文Preparing for Computer DisastersA: Summary: When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward.B: Fires, power surges, and floods, theyre all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate over their bad luck. We also shake our heads at the digital consequences—melted computers, system failures, destroyed data. Yet, somehow, many of us continue to live by that old mantra of denial: "It wont happen to me." Well, the truth is, at some point youll probably have to deal with at least one disaster. Thats just how it goes, and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disaster plans and run drills. But for some reason, computer disaster recovery is a blind spot for many of us. It shouldnt be. Home computers contain some of our most important information, both business and personal, and making certain our data survives a disaster should be a priority. Moreover, even the smallest disaster can be a serious disruption. Personal computers have become an integral part of the smooth-running household. We use them to communicate, shop, and do homework, and theyre even more vital to homeoffice users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. With a good offsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a major calamity strike, you can rest assured your data is safe.Offsite Storage: Major DisastersC: House fires and floods are among the most devastating causes of personal computer destruction. Thats why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their house flood our burn. Thats because they keep their backups in relatively close to their computers. Their backup disks might not be in the same room as their computers—tucked away in a closet or even the garage—but theyre not nearly far enough away should a serious disaster strike. So, its important to back up your system to a removable medium and to store it elsewhere.D: There are many ways to approach offsite storage. It starts with choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldnt add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in a pinch. They must also be compatible with your choice of backup medium. Depending on your tools, you can back up to a variety of durable disk types—from CDs to Jaz drives to remote network servers. Although many of these storage media have high capacity, a backuptool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.E: Once you select your tools and a suitable medium, you need to find a remote place to store your backups. The options are endless. However, no matter where you choose, be sure the site is secure, easily accessible, and a good distance away from your home. You may also want to consider using an Internet-based backup service. More and more service providers are offering storage space on their servers, and uploading files to a remote location has become an attractive alternative to conventional offsite storage. Of course, before using one of these services, make certain you completely trust the service provider and its security methods. Whatever you do, schedule backups regularly and store them far away from your home.Come What May: Handling the Garden Variety Computer CrisisF: Not all home computer damage results from physical disaster. Many less menacing problems can also hobble your PC or destroy your information. Systems crash, kids "rearrange" data, adults inadvertently delete files. Although these events might not seem calamitous, they can have serious implications. So, once again, its important to be prepared. As with physical disasters, regular backups are essential. However, some of these smaller issues require a response thats more nuanced than wholesale backup and restoration. To deal with less-than-total disaster, your tool set must be both powerful and agile. For example, when a small number of files are compromised, you may want to retrieve those files alone. Meanwhile, if just your settings are affected, youll want a simple way to roll back to your preferred setup. Yet, should your operating system fail, youll needa way to boot your computer and perform large-scale recovery. Computer crises come in all shapes and sizes, and your backup and recovery tools must be flexible enough to meet each challenge.The Right Tools for the Right Job: Gearing up for DisasterG: When disaster strikes, the quality of your backup tools can make the difference between utter frustration and peace of mind. Symantec understands this and offers a range of top quality backup and recovery solutions. Norton GoBack is the perfect tool for random system crashes, failed installations, and inadvertent deletions. With this powerful and convenient solution, its simple to retrieve overwritten files or to bring your system back to its pre-crash state. Norton Ghost is a time-tested home office solution. Equipped to handle full-scale backups, its also handy for cloning hard drives and facilitating system upgrades. A favorite choice for IT professionals, its the ideal tool for the burgeoning home office. You can buy Norton Ghost and Norton GoBack separately, or get them both when you purchase Norton System Works.H: Lifes disasters, large and small, often catch us by surprise. However, with a little planning and the right tools, you can reduce those disasters to bumps in the road. So, dont wait another day. Buy a good set of disaster recovery tools, set up an automatic backup schedule, and perform a dry run every now and again. Then, rest easy.英语六级段落匹配题题目1.

大学英语六级阅读段落匹配真题及答案因考试政策、内容不断变化与调整,下面给大家整理的高校阅读理解真题供参考,以下是我给大家整理的高校英语六级阅读段落匹配真题及答案,期望可以帮到大家Section ADirections: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.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.

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.
