2020年6月大学英语六级长篇阅读练习题(1)10 Ways Obama Could Fight Climate Change[A] One of the biggest surprises of President Barack Obama's inaugural address,on Monday was how much he focused on fighting climate change, spending more time on that issue than any other. "We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," Obama said. The President pointed out that recent severe weather supplied an urgent impetus for energy innovation and staked the nation's economic future on responding to a changing climate. "We cannot cede to other nations the technology that will power new jobs and new industries--we must claim its promise," Obama said. '" That's how we will maintain our economic vitality and our national treasure--our forests and waterways; our croplands and snowcapped (山顶积雪的) peaks. That is how we will preserve our planet, commanded to our care by God. " so what could the President reasonably do to deliver on that vow? Here are ten of their suggestions:Sunset coal with new incentives and regulations.[B] "Provide incentives to phase out the oldest, most polluting power plants," said Robert Jackson, a climate scientist at Duke University. It's already happening, to some degree, as more of the nation transitions to natural gas. Earth scientist Bill Chameides, dean of Duke's Nicholas School of the Environment and a former chief scientist at the Environmental Defense Fund, urges the administration to use its Clean, Air Act authority to promulgate (颁布)carbon regulations for existing power plants like it has for new ones: "Doing that will force fuel switching from coal to natural gas. "Invest federal stimulus money in nuclear power.[C] It's hardly a perfect fuel, as accidents like Japan's Fukushima fallout have shown, but with safety precautions new nuclear plants can meaningfully offset dirtier types of energy, supporters say."Nuclear is the only short-to medium-term way to really get away from fossil fuels," said Peter Raven. President emeritus of the Missouri Botanical Garden. He said the damage done by relentless global warming will far exceed the damage done by faults in the nuclear system.Kill the Keystone pipeline.[D] The controversial Keystone XL oil pipeline is up for review again by the White House this year. "The font thing he should do to set the tone to a lowercarbon economy is to reject the Keystone pipeline, “said Raymond Pierrehum Bert, a geophysical scientist at the University of Chicago. The pipeline was never going to be a major driver of global emissions, but Pierre humbert and some other environmentalists say that by killing it the President would send a clear message about America's intent to ramp down fossil fuels.Protect the oceans by executive order.[E] Land use is complicated, but large swaths of oceans can be protected by executive order. Just as President George W. Bush designated the world's largest marine monument northwest of Hawaii in 2006. Obama could single-handedly protect other areas. National Geographic Explorer-in-Residence Sylvia Earle said the President should focus on parts of the Arctic that are under U. S. control, putting them off limits to energy production, commercial fishing, and mineral exploration. Marine sanctuaries (禁捕区) won't stop climate change, but they can give marine species a better chance of adapting to it by reducing the other man-made threats the animals face.Experiment with capturing carbon.[F] Huge untapped reserves of natural gas and oil make it unlikely that the U. S. will transition away from fossil fuels in the immediate future. Instead, said Wallace Broecker, geology professor at Columbia University's Lamont-Doherty Earth Observatory, we should attack the atmosphere's carbon surplus directly. "Obama could make available funds to build and test prototype air capture units" to capture and store CO2, said Broecker. Removing some carbon from the atmosphere could buy valuable time as policy makers and scientists explore more permanent solutions.Grow government research for new energy sources.[G] The Department of Energy has a nimble program that's tasked with innovative energy research—the Advanced Research Projects Agency-Energy. The ARPA-E funds research in biofuels, transmission,and battery storage, with an annual budget of $ 275 million. Last year, DOE officials requested at least $ 75 million more. Increasing funding for ARPA-E, said Rare Pomerance, former deputy assistant secretary of state for environment and development and currently an environmental consultant, "you get new technologies that undercut coal, oil, and gas. " Plus, he said, yon get a competitive advantage if American researchersuncover the next big idea in new energy.Tax carbon.[H] Congress would have to agree, but many climate experts say that the most meaningful way to tackle emissions is to set a price on carbon. "We should be asking people to pay the cost of putting carbon into the atmosphere as they buy the fuel," said Josh Willis, climate scientist and oceanographer at NASA's Jet Propulsion Laboratory. To gain political support for the idea, Obama would probably have to show that the tax wonld help accelerate technology, grow new industries, and pay down the deficit.Dial back the federal government's energy use.[I] With more than I. 8 million employees, $ 500 billion in annual purchasing power, and 500,000 buildings to operate, the federal government has been a leader in reducing energy use since Obama signed a 2009 executive order to cut waste. "I would urge him to keep using the power of government to promote energy conservation," said Syndonia Bret-Harte, an Arctic biologist who studies climate change at the University of Alaska, Fairbanks.Build a scientific clearinghouse for climate information.[J] "I advocate for building a better information system on what is happening and why," said Kevin Tren berth, head of the Climate Analysis Section at the U. S. National Center for Atmospheric Research. That involves compiling observations related to climate change from around the world and using the data to refine climate modeling. Think of it as a one-stop, user-friendly website that clearly demonstrates how weather data from around the globe are influenced by broader shifts in the planet's climate.Keep talking. Despite a consensus among top scientists, the world still needs some convincing on climate change.[K] A CNN poll last week found that just 49 percent of Americans agree that global warming is real and is due to human activities. "The most important thing the President can do is to build on his inaugural comments to heighten the sense of urgency about rapid climate destabilization and clarify its connection to virtually every other issue on the national agenda," said David Orr, environmental studies professor at Oberlin College. That means using the bully clergymen to show how a more volatile climate affects everything from agriculture totransportation to 21st-century warfare.46. The urge to promulgate carbon regulations is aimed at pushing power plants to replace coal by natural gas.47. Marine sanctuaries should be preserved because they help sea species adapt to climate alteration.48. The government should take the responsibility to raise Americans' awareness about climate change.49. Many climate experts believe that the most effective way to lower emission is to tax on carbon.50. Nuclear supporters argue that nuclear system failures are less challenging than global warming.51. Recent extreme weather made President Obama feel it is urgent to address climate change.52. Keystone pipeline should be rejected because it is a signal to reduce fossil fuels.53. Since Obama signed a 2009 executive order to cut waste, the federal government has taken the lead in saving energy.54. Lower carbon emission will be most likely to happen if research in new energy resources succeeds.55. Compared with turning to new energy, America prefers carbon capture and store as a temporary measure.2020年6月大学英语六级长篇阅读练习题(2)How to Make Attractive and Effective PowerPoint PresentationsA) Microsoft PowerPoint has dramatically changed the way in which academic and business presentations are made. This article outlines few tips on making more effective and attractive PowerPoint presentations.The TextB) Keep the wording clear and simple. Use active, visual language. Cut unnecessary words—a good rule of thumb is to cut paragraphs down to sentences, sentences into phrases, and phrases into key words.Limit the number of words and lines per slide. Try the Rule of Five-five words per line, five lines per slide. If too much text appears on one slide, use the AutoFit feature to split it between two slides. Click within the placeholder to display the AutoFit Options button (its symbol is two horizontal lines with arrows above and below), then click on the button and choose Split Text between Two Slides from the submenu.C) Font size for titles should be at least 36 to 40, while the text body should not be smaller than e only two font styles per slide—one for the title and the other for the text. Choose two fonts that visually contrast with each other. Garamond Medium Condensed and Impact are good for titles, while Garamond or Tempus Sans can be used for the text body.D) Embed the fonts in your presentation, if you are not sure whether the fonts used in the presentation are present in the computer that will be used for the presentation. To embed the fonts: (1) On the File menu, click Save As. (2) On the toolbar, click Tools, click Save Options, select the Embed TrueType Fonts check box, and then select Embed characters in use only.E) Use colors sparingly; two to three at most. You may use one color for all the titles and another for the text body. Be consistent from slide to slide. Choose a font color that contrasts well with the background.F) Capitalizing the first letter of each word is good for the title of slides and suggests a more formal situation than having just the first letter of the first word capitalized. In bullet point lines, capitalize the first word and no other words unless they normally appear capped. Upper and lower case lettering is more readable than all capital letters. Moreover, current styles indicate that using allcapital letters means you are shouting. If you have text that is in the wrong case, select the text, and then click Shift+F3 until it changes to the case style that you like. Clicking Shift+F3 toggles the text case between ALL CAPS, lower case, and Initial Capital styles.G) Use bold or italic typeface for emphasis. Avoid underlining, it clutters up the presentation.Don’t center bulleted lists or text. It is confusing to read. Left align unless you have a good reason not to. Run “spell check” on your show when finished.The BackgroundH) Keep the background consistent. Simple, light textured backgrounds work well. Complicated textures make the content hard to read. If you are planning to use many clips in your slides, select a white background. If the venue of your presentation is not adequately light-proof, select a dark-colored background and use any light color for text. Minimize the use of “bells and whistles” such as sound effects, “flying words” and multiple transitions. Don’t use red in any fonts or backgrounds. It is an emotionally overwhelming color that is difficult to see and read.The ClipsI) Animations are best used subtly; too much flash and motion can distract and annoy viewers. Do not rely too heavily on those images that were originally loaded on your computer with the rest of Office. You can easily find appropriate clips on any topic through Google Images. While searching for images, do not use long search phrases as is usually done while searching the web-use specific words.J) When importing pictures, make sure that they are smaller than two megabytes and are in a .jpg format. Larger files can slow down your show. Keep graphs, charts and diagrams simple, if possible. Use bar graphs and pie charts instead of tables of data. The audience can then immediately pick up the relationships.The PresentationK) If you want your presentation to directly open in the slide show view, save it as a slide show file using the following steps. Open the presentation you want to save as a slide show. On the File menu, click Save As. In the Save astype list, click PowerPoint Show. Your slide show file will be saved with a ppt file extension. When you double-click on this file, it will automatically start your presentation in slide show view. When you’re done, PowerPoint automatically closes and you return to the desktop. If you want to edit the slide show file, you can always open it from PowerPoint by clicking Open on the File menu.L) Look at the audience, not at the slides, whenever possible. If using a laser pointer, don’t move it too fast. For examp le, if circling a number on the slide, do it slowly. Never point the laser at the audience. Black out the screen (use “B” on the keyboard) after the point has been made, to put the focus on you. Press the key again to continue your presentation.M) You can use the shortcut command [Ctrl]P to access the Pen tool during a slide show. Click with your mouse and drag to use the Pen tool to draw during your slide show. To erase everything you’ve drawn, press the E key. To turn off the Pen tool, press [Esc] once.MiscellaneousN) Master Slide Set-Up: The “master slide” will allow you to make changes that are reflected on every slide in your presentation. You can change fonts, colors, backgrounds, headers, and footers at the “master slide” level. First, go to the “View” menu. Pull down the “Master” menu. Select the “slide master” menu. You may now make changes at this level that meet your presentation needs.1. The ways in which academic and business presentations are made have been changed by Microsoft PowerPoint.2. When making the PowerPoint, the wording of the text should not be complicated.3. In each slide, the font styles for the title and the text should contrast with each other.4. A more formal situation is capitalizing the first letter of the first word.5. Centering bulleted lists or text can not help to read.6. Sound effects should be used as less frequently as possible.7. When importing pictures, make sure that they are smaller than two megabytes.8. When making the presentation, you should look at the audience as possible as you can.9. Pressing the E key can help you to erase everything you've drawn.10. In order to meet your presentation needs, you can make changes at the “slide master”level.2020年6月大学英语六级长篇阅读练习题(3)Paper--More than Meets the EyeA) We are surrounded by so much paper and card that it is easy to forget just how complex it is. There are many varieties and grades of paper materials, and whilst it is fairly easy to spot the varieties, it is far more difficult to spot the grades.B) It needs to be understood that most paper and card is manufactured for a specific purpose, so that whilst the corn-flake packet may look smart, it is clearly not something destined for the archives. It is made to look good, but only needs a limited life span. It is also much cheaper to manufacture than high grade card.C) Paper can be made from an almost endless variety of cellulose-based material which will include many woods, cottons and grasses or which papyrus is an example and from where we get the word "paper". Many of these are very specialized, but the preponderance of paper making has been from soft wood and cotton or rags, with the bulk being wood-based.Paper from WoodD) In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery and then boiled with strong alkalies such as caustic soda, until a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made, relying on the bonding together of the cellulose into layers. That, in a very small nutshell, is the essence of paper making from wood. However, the reality is rather more complicated. In order to give us our white paper and card, the makers will add bleach and other materials such as china clay and additional chemicals.E) A further problem with wood is that it contains a material that is not cellulose. Something called lignin. This is essential for the tree since it holds the cellulose fibres together, but if it is incorporated into the manufactured paper it presents archivists with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look rather brown and careworn. We have all seen this in old newspapers and cheap paperback books. It has been estimated that most paper back books will have a life of not greaterthan fifty years. Not what we need for our archives.F) Since the lignin can be removed from the paper pulp during manufacture, the obvious question is "why is it left in the paper?" The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tree to some 95%. Removing it means a yield of only 35%. It is clearly uneconomic to remove the lignin for many paper and card applications.G) It also means, of course, that lignin-free paper is going to be more expensive, but that is nevertheless what the archivist must look for in his supplies. There is no point whatsoever in carefully placing our valuable artifacts in paper or card that is going to hasten their demise. Acid is particularly harmful to photographic materials, causing them to fade and is some cases simply vanish!H) So, how do we tell a piece of suitable paper or card from one that is unsuitable? You cannot do it by simply looking, and rather disappointingly, you cannot always rely on the label. "Acid-free" might be true inasmuch as a test on the paper may indicate that it is a neutral material at this time. But lignin can take years before it starts the inevitable process of breaking down, and in the right conditions it will speed up enormously.I) Added to this, as I have indicated earlier, paper may also contain other materials added during manufacture such as bleach, china clay, chemical whiteners and size. This looks like a bleak picture, and it would be but for the fact that there are suppliers who will guarantee the material that they sell. If you want to be absolutely sure that you are storing in, or printing on, the correct material then this is probably the only way.J) Incidentally, acids can migrate from material to material. Lining old shoe boxes with good quality acid-free paper will do little to guard the contents. The acid will get there in the end.Paper from RagK) Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free, but because there is much less cotton and rag than trees, it also tends to be much more expensive than wood pulp paper. You will still need to purchase from a reliable source though, since even rag paperand card can contain undesirable additives.L) A reliable source for quality rag papers is a recognized art stockiest. Many water color artists insist on using only fine quality rag paper and board.M) The main lesson to learn from this information is that you cannot rely on purchasing archival materials from the high street. The only safe solution is to purchase from specialist suppliers. It may cost rather more, but in the end you will know that your important and valuable data and images have the best home possible.1. The corn-flake packet is cheaper than high grade card.2. There are a lot of materials which can be used for making paper, but the superiority ones are soft wood, cotton and rags.3. During the whole manufacturing process, the final product is made froma pulp of cellulose fibres.4. In order to make white paper and card, the makers will add bleach.5. Liguin is essential for the tree but it will make paper easy to break.6. Many paper producers will preserve lignin during manufacture, because leaving the lignin will make more paper from a tree.7. Acid is particularly harmful to photographic materials.8. If the lignin is removed from the paper, the paper will be more expensive.9. Although free of lignin, paper made from cotton and rag waste can also cost more money than wood pulp paper because there is much less cotton and rag than trees.10. What we can learn from "Paper from Rag" is that you had better buy archival materials from specialist suppliers.2020年6月大学英语六级长篇阅读练习题(4)Definitions of ObesityA: How does one define when a person is considered to be obese and not just somewhat overweight? Height-weight tables give an approximate guideline as to whether one is simply overweight or has passed into the obese stage.B: The World Health Organization recommends using a formula that takes into account a person's height and weight. The "Body Mass Index" (BMI) is calculated by dividing the person's weight in kilograms by the square of their height in meters, and is thus given in units of kg/m2. A BMI of 18.5-24.9 is considered to be the healthiest. A BMI of between 25 and 29.9 is considered to be overweight, while a BMI of over 30 is considered to be obese.C: However, it is recognized that this definition is limited as it does not take into account such variables as age, gender and ethnic origin, the latter being important as different ethnic groups have very different fat distributions. Another shortcoming is that it is not applicable to certain very muscular people such as athletes and bodybuilders, who can also have artificially high BMIs. Agencies such as the National Cholesterol Education Program (NCEP) in the USA and the International Diabetes Foundation (IDF) are starting to define obesity in adults simply in terms of waist circumference.Health Effects of ObesityD: Over 2000 years ago, the Greek physician Hippocrates wrote that "persons who are naturally very fat are apt to die earlier than those who are slender". This observation remains very true today. Obesity has a major impact on a person's physical, social and emotional well-being. It increases the risk of developing diabetes mellitus type 2 ("mature onset diabetes") and also makes Type 2 diabetes more difficult to control. Thus weight loss improves the levels of blood glucose and blood fats, and reduces blood pressure. The association between obesity and coronary heart disease is also well-known.CancerE: Furthermore, in 2001 medical researchers established a link between being overweight and certain forms of cancer, and estimated that nearly 10,000 Britons per year develop cancer as a result of being overweight. This figure was made up of 5,893 women and 3,220 men, with the strongest associations beingwith breast and colon cancers. However, it is thought that being overweight may also increase the risk of cancer in the reproductive organs for women and in the prostate gland for men.F: The link between breast cancer and nutritional status is thought to be due to the steroid hormones oestrogen and progesterone, which are produced by the ovaries, and govern a woman's menstrual cycle. Researchers have found that the more a woman eats, or the more sedentary her lifestyle, the higher are the concentrations of progesterone. This link could explain why women from less affluent countries have lower rates of breast cancer. Women from less affluent nations tend to eat less food and to lead lifestyles which involve more daily movement. This lowers their progesterone level, resulting in lower predisposition to breast cancer.G: The Times newspaper, in 2002 reported that obesity was the main avoidable cause of cancer among non-smokers in the Western world!AgingH: Research published by St Thomas' Hospital, London, UK in 2005 showed a correlation between body fat and aging, to the extent that being obese added 8.8 years to a woman's biological age. The effect was exacerbated by smoking, and a non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to their biological age. The combination of being obese and a smoker added at least ten years to a woman’s biological age, and although the study only involved women, the lead researcher Professor Tim Spector believes the finding would also apply to men.I: The aging effect was determined by measuring the length of telomeres, tiny "caps" on the ends of chromosomes, which help protect the DNA from the ageing process. Indeed, telomeres have been dubbed the "chromosomal clock" because, as an organism ages, they become progressively shorter, and can be used to determine the age of the organism. Beyond a certain point, the telomere becomes so short that it is no longer able to prevent the DNA of the chromosome from falling apart. It is believed that excess body fat, and the chemicals present in tobacco smoke release free radicals which trigger inflammation. Inflammation causes the production of white blood cells which increases the rate of erosion of telomeres.DementiaJ: Recent research (2005) conducted in the USA shows that obesity in middle age is linked to an increased risk of dementia, with obese people in their40s being 74% more likely to develop dementia compared to those of normal weight. For those who are merely overweight, the lifetime risk of dementia risk was 35% higher.K: Scientists from the Aging Research Centre at the Karolinska Institute in Sweden have been able to take information such as age, number of years in education, gender, body mass index, blood pressure level, physical activity and genetic factors, assigning each a risk score. They then used this information to devise a predictive test for dementia. This test will enable people at risk, for the first time, to be able to affect lifestyle changes which will reduce their risk ofcontracting dementia.Other ProblemsL: The world-wide upsurge in obesity, particularly in children, is of major economic concern, liable to drain economies. Of further concern is that research conducted in Australia and published in 2006, shows that up to one third of breech pregnancies were undetected by the traditional "palpation" examination, the danger being greatest for those women who are overweight or obese—a growing proportion of mothers. This means that such women are not getting the treatment required to turn the baby around in time for the birth, and in many cases require an emergency Caesarean section.M: This is a true health-care crisis, far bigger than Severe Acute Respiratory Syndrome (SARS) and ultimately, even bigger than AIDS.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 a person's weight ideal is limited, because it does not takes into account many variables such as age, gender and ethnic origin.3. A person's emotional 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 have much less breast cancer.6. A non-overweight woman who smokes 20 cigarettes a day for 20 years added7.4 years to her biological age.7. The excess body fat, like the chemicals present in tobacco smoke, 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 changes that will reduce their risk of contracting dementia.10. The world-wide upsurge in obesity, particularly in children, will possibly drain economies.。

英语六级阅读真题训练1Some futurologists have assumed thatthe vast upsurge (剧增) of women in the workforce mayportend a rejection ofmarriage. Many women, according to this hypothesis, would ratherwork thanmarry. The converse (反面) of this concern is that the prospects of becomingamulti-paycheck household could encourage marriages. In the past, only theearnings andfinancial prospects of the man counted in the marriage decision.Now, however, the earningability of a woman can make her more attractiveas a marriage partner. Data show thateconomic downturns tend to postponemarriage because the parties cannot afford to establisha family or areconcerned about rainy days ahead. As the economy rebounds, the numberofmarriages also rises.Coincident with the increase in women working outside the home isthe increase in divorcerates. Yet, it may be wrong to jump to any simplecause-and-effect conclusions. The impact ofa wife’s work on divorce is noless cloudy than its impact on marriage decisions. The realizationthat she canbe a good provider may increase the chances that a working wife willchoosedivorce over an unsatisfactory marriage. But the reverse is equallyplausible. Tensionsgrounded in financial problems often play a key role inending a marriage. Given highunemployment, inflationary problems, andslow growth in real earnings, a working wife canincrease household incomeand relieve some of these pressing financial burdens. By raising afamily’s。

大学英语六级阅读精选试题及答案All things are difficult before they are easy.以下是为大家搜索的大学阅读精选试题及答案,希望能给大家带来帮助!更多精彩内容请及时关注我们!The destruction of our natural resources and contamination of our food supply continue our, largely because of the extreme difficulty in affixing (把…固定) legal responsibility on those who continue to treat our environment with reckless abandon (放任). Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been by lawsuits, personal and industrial denial and long delays—not only in aepting responsibility, but more importantly, in doing something about it.It seems that only when government decides it canafford tax incentives or production sacrifices is there any initiative for change. Where is industry’s a nd our recognition that protecting mankind’s great treasure is the single most important responsibility? If ever therewill be time for environmental health professionals to e to the frontlines and provide leadership to solve environmental problems, that time is now.We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health tomake the difference. Yes, the ecologists, the environmental activists and the conservationists serve to municate, stimulate thinking and promote behavioral change. However,it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge.We must recognize that environmental health issues donot stop at city limits, county lines, state or evenfederal boundaries. We can no longer afford to be tunnel-visioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion.I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to municate technical information in a form that citizens can understand. If we can aomplish these three goals in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages.16. We can infer from the first two paragraphs that the industrialists disregard environmental protection chiefly because .A) they are unaware of the consequences of what they are doingB) they are reluctant to sacrifice their own economic interestsC) time has not yet e for them to put due emphasis on itD) it is difficult for them to take effective measures17. The main task now facing ecologists, environmental activists and conservationists is .A) to prevent pollution by legislation, economic incentives and persuasionB) to arouse public awareness of the importance of environmental protectionC) to take radical measures to control environmental pollutionD) to improve the quality of life by enforcing environmental standards18. The word “tunnel-visioned (Line 2, Para. 4) most probably means “”.A) narrow-mindedB) blind to the factsC) short-sightedD) able to see only one aspect19. Which of the following, aording to the author, should play the leading role in the solution of environmental problems?A) Legislation and government intervention.B) The industr y’s understanding and support.C) The efforts of environmental health professionals.D) The cooperation of ecologists, environmental activists and conservationists.20. Which of the following is true aording to the last paragraph?A) Efforts should be exerted on pollution prevention instead of on remedial measures.B) More money should be spent in order to stop pollution.C) Ordinary citizens have no aess to technical information on pollution.D) Environmental degradation will be stopped by the end of this decade.。

英语六级阅读理解真题卷及答案-3因考试政策、内容不断变化与调整,下面是给大家供应的阅读理解范文供参考,以下是我给大家整理的英语六级长篇阅读真题-3,期望可以帮到大家whos really addicting you to Technology?A.Nearly everyone i know is addicted in some measure to the internet, wrote tony Schwartz in The New York Times. its a common complaint these days. A steady stream of similar headlines accuse the net and its offspring apps, social media sites and online games of addicting us to distractionB. Theres little doubt that nearly everyone who comes in contact with the net has difficulty concentration than it takes to post a status update. as one person ironically put it in the comments section of Schwartzs online article, As I was reading this very excellent article.I stopped at least half a dozen times to cheek my email.C.Theres something different about this technology: it is both invasive and persuasive. but whos at fault for its overuse? To find solutions, its important to understand what were dealing with.There are four parties conspiring to keep you connected the tech, your boss, your friends and you.D.The technologies themselves and their makers, are the easiest suspects to blame for our diminishing attention spans. Nicholas Carr,author of The Shallows: what the internet isdoing Our brains, wrote, The net is designed to be an interruption system, a machine geared to dividing attention.E.Online services like Facebook, twitter and the like, are called out of manipula-tion--making,products so good that people cant stop using them. after studying these products for several years, I wrote a book about how they do it. I learned it all starts with the business model. since these services rely on advertising revenue, The more frequently you use money they make.Its no winder these companies employ teams of people focused on engineering their services to be as engaging as possible. these products arent habit-forming by chance; its by design. they have an incentive to keep us hooked.F.However, as good as these services are, there are simple steps we can take to keep them at bay.For example, we can change how often we receive the distracting notifications that trigger our urge to check.According to adam marchick, ceo of mobile marketing company kahuna, less than 15 percent of smartphone users ever bother to adjust their notificationsetlings--meaning the remaining 85 percent of us default to the app makers every preset trigger.Google and Apple have made it far too difficult to adjust these settings so its up to us to take steps ensure we set these triggers to suit our own needs, not the needs of the app makers.G.While companies like Facebook harvest attention to generate revenue from advertisers, other technologies have no such agenda. take email, for example. this system couldnt care less how often you use it. Yet to many, email is the most habit-forming medium of all.We check email at all hours of theday--were obsessed, but why? Because thats what the boss wants.For almost all white-collar jobs, A slowResponse to a message could hurt not only your reputation but also your livelihood.H.Your friends are also responsible.Think about this familiar scene.People gathered around a table, enjoying food and each others company. theres laughter and a bit of kidding. Then, during an interval in the conversation, someone takes out their phone to check who knows what.Barely anyone notices and no one says a thing.I.Now imagine the same dinner,but instead of checking their phone, the person belches(打嗝)-loudly.Everyone notices. unless the meal takes place in a beer house, this is considered bad manners. The impolite act violates the basic rules of etiquette. one has to wonder why dont we apply the same social norms to checking phones during meals, meetings and conversations as we do to other antisocial behaviors somehow, we accept it and say nothing when someone offends.J.The reality is taking ones phone out at the wrong time is worse than belching because, unlike other minor offense, checking tech is contagious. once one person looks at their phone,other people feel compelled to do the same, starting a chain reaction. the more people are on their phones, the fewer people are talking until finally you are the only one left not reading email or checking twitter. from a societal perspective, phone checking is less like belching in public and more like another bad habit. our phones are like cigarettes-something todo when were bored or when our fingers need something to toy with seeing others enjoy a smoke,or sneak a quick glance, is too tempting to resist and soon everyone is doing it.K.The technology, your boss, and your friends, all influence how often you find yourself using (oroverusing )these gadgets. but theres still someone who deserves scrutiny--the person holding the phone.L. I have a confession. even though i study habit-forming technology for a living, disconnecting is not easy for me.Im online far more than Id like like Schwartz and so many others, I often find myself distracted and off tack.I wanted to know why so i began self-monitoring to try to understand my behavior. thats when i discovered an uncomfortable truth. i use technology as an escape. when Im doing something Id rather not do, or when Im someplace Id rather not attention was often a good thing, like when passing time on public transportation, but frequently my tech use was not so benign. when i faced difficult work, like thinking through an article idea or editing the same draft for the hundredth time, for example, a more sinister screen would draw me in. i could easily escape discomfort.temporarlly.by answering email or browsing ing the web under the pretense of so-calledresearch. though I desperately wanted to lay blame elsewhere, i finally had to admit that my bad habits had less to do with new-age.technology and more to do with old-fashioned procrastination(拖延)M.its easy to blame technology for being so distracting, but distraction is nothing new. Aristotle and Socrates dehated nature of “akrasia”--our tendency to do things agninst ourinterests. If were honest with ourselves, tech is just another way to occupy our time and minds,if we werent on our devices. Wed likely do similarly unproductive.N.personal technology is indeed more engaging than ever, and theres no doubt companies are engineering their products and services to be more compelling and attractive but would want it any other way the intended result of making something better is that people use it more. thats not necessarily a problem, thats progress.O.These improvements dont mean we shouldnt attempt to control our use of technology. In order to make sure it doesnt control us, we should come to terms with the fact that its more than the technology itself thats responsible for our habits. our workplace culture, social norns and individual behaviors all play a part to put technology in its place, we must be conscious not only of how technology is changing, but also of how it is changing us.36.Online services are so designed that the more they are used, the more profit they generate.37. The author admits using technology as an escape from the task at hand.38. Checking phones at dinners is now accepted as normal but not belching39. To make proper use of technology, we should not only increase our awareness of how it is changing but also how itis impacting us.40. Most of us find it hard to focus on our immediate tasks because of internet distractions41. when one person starts checking their phone, the others will follow suit.42.The great majority of smartphone users don t take the trouble to adjust their settings to suit their own purposes.43.The internet is regarded by some as designed to distract our attention.44.

out today’s teenagers aren’t so scary after all.Results of USA WEEKEND’s Teens&Parents survey reveal a generation of young people who get along well with their parents and approve of the way they’re being raised.They think of their parents with affection and respect.They speak with Mom or Dad when they have a problem.Most feel that their parents understand them.and they believe their family is the No.1 priority in their parents’lives.Many even think their parents are cool!Although more than a third have an object in their rooms they would like to keep secret from their parents.rarely is it anything more alarming than a diary or off-color(低俗的) book or CD.[B] Such results may seem surprising against the background of shocking incidents that color the way the mass media portray the young.In October 2000,the same month the survey was taken,the Washington. based Center for Media and Public Affairs wrote in its publication Media Monitor that,in a recent month of TV news coverage of American youth,just 2%of teens were shown at home,and just 1%were portrayed in a work setting.In contrast,the criminal justice system accounted for nearly one out of every lave visual backgrounds.No wonder parents worry their own kids might spin out of control once they hit the turbulent waters of adolescence.[C] The overall facts ought to reassure us.The survey shows us that today’s teens are affectionate.sensible and tar h appier than the angry and tortured souls that have been painted for us by stereotypes.From other sources,we also know teenage crime,drug abuse and premarital sex are in general decline.We of course,need to pay attention to youngsters who are filled with discontent and hostility,but we should not allow these extreme cases to distort our view of most young people.[D] My own research at the Stanford Center on Adolescence uses in.depth interviews with small samples of youngsters rather than large ‘scale survey s.Still,in my studies and others I have read,I find the same patterns as in USA WEEKEND’s survey.Today’s teenagers admire their parents and welcome parental guidance about important matters such as career choice—though certainly not Morn and Dad’s advice o n matters of personal taste,such as music or fashion.When we ask teens to choose a hero,they usually select an older family member rather than a remote public figure.Most teens say they enjoy the company of both parents and friends.[E] Contrary to some stereotypes,most adolescents believe they must be tolerant of differences among individuals(though they do not always find this easy in the cliquish(拉帮结派的)environment of highschool).Many of them volunteer for community service with disadvantaged people.One prevalent quality we have round in teens’statements about themselves,their friends and their families is a strikingly positive emotional tone.By and large,these are very nice kids,and as the band The Who used to sing,“The kids are alright.”[F] How much is today’s sprat of harmony a change fromour more turbulent past?A mere generation ago,parent。

Dr. Helen Adam from Edith Cowan University’s School of Education 26 the cultural diversity of children’s books. She examined the books 27 in the kindergarten rooms of four day-care centers in Western Australia. Just 18 percentof 2,413 books in the total collection contained any 28 of non-white people. Minority cultures were often featured in stereotypical or tokenistic ways, for example, by 29 Asian culture with chopsticks and traditional dress. Characters that did represent a minority culture usually had 30 roles in the books. The main characters were mostly Caucasian. This causes concern as it can lead to an impression that whiteness is of greater value.Dr. Adam said children formed impressions about “difference” and identity from a very young age. Evidence has shown they develop own-race 31 from as young as three months of age. The books we share with young children can be a valuable opportunity to develop children’s understanding of themselves and others. Books can also allow children to see diversity.

英语六级阅读理解专练题(一)In the United States, where“casualness”is considereda great virtue, people often sit with feet on chairs oreven desks. They sometimes sit with their backsides( buttocks) on tables and desks as a way ofexpressing their individuality or career attitude.They feel comfortable crossing their legs and sittingwith one ankle on the other knee . Poor posture —slumping oneself over while sitting in a chair and placing feet on whatever object is around — isa common U. S. behavior. It is designed to show that the perso n is casual, honest, sincere,and“ just one of the folks ”. In the United States, even millionaires, corporation presidents,government leaders, and movie stars try to pretend they are ordinary people by using“the U.S. slouch ”and“ the feet-on-the -furniture”maneuver.Unfortunately, other countries interpret this behavior as being sloppy and as reflecting ageneral lack of alertness, interest, and respect. People from the United States do not usuallyrealize that what they regard as casualness is viewed very differently and very negatively bymany people around the world.People in many cultures are expected to sit erect. Such cultures include many countriesin LatinAmerica, Asia, Europe, and the Middle East. In the United States, slouching is acceptable and isa positive sign of being casual and friendly. In the United States, crossing legs is a sign of goodetiquette . Many cultures say thatcrossing legs is okay, but placing the ankle on the kneewhilecrossing one’s legs is totally unacceptable .One reason for not putting the ankle on the knee is that when you do so, one foot or the soleof the shoe is usually pointing at someone . This is a very severe insult in many countriesaround the world, especially Muslim countries. Under few circumstances should you point yourfoot at anyone , because the foot is cons idered the least sacred part of the body in manysocieties. In some countries such as Nepal, pointing the foot at a cow is an outrage , becausethe cow is a sacred animal. In Buddhist countries, pointing the foot at statue of the Buddha isa severe offense. Moving objects with the feet is very rude in Thailand, Nepal, and Taiwan. InBangladesh, you should not touch books with a foot or shoe; if you do, you must make anelaborate apology.As you can tell, posture is a very strong messenger. It conveys much about a particu larperson. Posture ( in many cultures) says something about the person’s honesty, alertness,intelligence, religiousness, respect, and overall decency — or the opposite of all of these !Posture tells people whether they want to get to know a stranger, and it also tells what to thinkabout the people already known.阅读自测Translate the sentences into English with the words in parentheses :1. 这座纪念碑是为内战中牺牲的烈士们而建立的。

2021年6月大学英语六级仔细阅读练习题附答案及解析(4)

2021年6月大学英语六级仔细阅读练习题附答案及解析(4)Passage OneQuestions 56 to 60 are based on the following passage.They're still kids, and although there's a lot that the experts don't yet know about them, one thing they do agree on is that what kids use and expect from their world has changed rapidly. And it's all because of technology.To the psychologists, sociologists, and generational and media experts who study them, their digital gear sets this new group apart, even from their tech-savvy (懂技术的) Millennial elders. They want to be constantly connected and available in a way even their older siblings don't quite get. These differences may appear slight, but they signal an all-encompassing sensibility that some say marks the dawning of a new generation.The contrast between Millennials and this younger group was so evident to psychologist Larry Rosen of California State University that he has declared the birth of a new generation in a new book, Rewired: Understanding the ingeneration and the Way They Learn, out next month. Rosen says the tech-dominatedlife experience of those born since the early 1990s is so different from the Millennials he wrote about in his 2021 book, Me, MySpace and I: Parenting the Net Generation, that they warrant the distinction of a new generation, which he has dubbed the "ingeneration"."The technology is the easiest way to see it, but it's also a mind-set, and the mind-set goes with the little ‘i', which I'm talking to stand for 'individualized'," Rosen says. "Everything is defined and individualized to ‘me'. My music choices are defined to ' me'. What I watch on TV any instant is defined to ‘me'. " He says the iGeneration includes today's teens and middle-school ers, but it's too soon to tell about elementary-school ages and younger.Rosen says the iGeneration believes anything is possible. "If they can think of it, somebody probably has or will invent it," he says. "They expect innovation."They have high expectations that whatever they want or can use "will be able to be tailored to their own needs and wishes and desires."Rosen says portability is key. They are inseparable from their wireless devices, which allow them to text as well as talk, so they can be constantly connected-even in class, where cellphones are supposedly banned.Many researchers are trying t6 determine whether technology somehow causes the brains of young people to be wired differently. "They should be distracted and should perform more poorly than they do," Rosen says. "But findings show teens survive distractions much better than we would predict by their age and their brain development. "Because these kids are more immersed and at younger ages, Rosen says, the educational system has to change significantly."The growth curve on the use of technology with children is exponential(指数的), and we run the risk of being out of step with this generation as far as how they learn and how they think," Rosen says."We have to give them options because they want their world individualized. "56. Compared with their Millennial elders, the iGeneration kidsA.communicate with others by high-tech methods continually B.prefer to live a virtual life than a real oneC.are equipped with more modem digital techniquesD.know more on technology than their elders57. Why did Larry Rosen name the new generation asiGeneration?A.Because this generation is featured by the use of personal high-tech devices.B.Because this generation stresses on an individualized style of life.C.Because it is the author himself who has discovered the new generation.D.Because it's a mind-set generation instead of an age-set one.58. Which of the following is true about the iGeneration according to Rosen?A.This generation is crazy about inventing and creating new things.B.Everything must be adapted to the peculiar need of the generation.C.This generation catches up with the development of technology.D.High-tech such as wireless devices goes with the generation.59. Rosen's findings suggest that technologyA.has an obvious effect on the function of iGeneration's brain developmentB.has greatly affected the iGeneration's behaviors and academic performanceC.has no significantly negative effect on iGeneration's mental and intellectual developmentD.has caused distraction problems on iGeneration which affect their daily performance60. According to the passage, education has to __A.adapt its system to the need of the new generationB.use more technologies to cater for the iGenerationC.risk its system to certain extent for the iGeneration D.be conducted online for iGeneration's individualized needPassage TwoQuestions 61 to 65 are based on the following passage.Small increases in temperature found to add power to storms in the Atlantic.Hurricanes that form in the Atlantic Ocean are expected to gain considerable strength as the global temperature continues to rise, a new study has found.Using modeling data focused on the conditions in which hurricanes form, a group of international researchers based at Beijing Normal University found that for every 1.8°F( 1℃)rise of the Earth's temperature, the number of hurricanes in the Atlantic that are as strong or stronger than Hurricane Katrina will increase twofold to sevenfold.Hurricane strength is directly related to the heat of the water where the storm forms. More water vapor in the air from evaporating ocean water adds fuel to hurricanes that build strength and head toward land.Hurricane Katrina is widely considered the measure for a destructive storm, holding the maximum Category 5 designation for a full 24 hours in late August 2005. It lost strength as it passed over the Florida peninsula, but gained destructive power fight before colliding with New Orleans, killing more than 200 people and causing $ 80 billion in damage.The study points to a gradual increase of Katrina-like events. The warming experienced over the 20th century doubled the number of such debilitating(将人类摧垮的)storms. But the ongoing warming of the planet into the 21st century could increase the frequency of the worst kinds of storms by 700 percent, threatening coastlines along the Atlantic Ocean with muitiple Category 5 storms every year."Our results support the idea that changes in regional sea surface temperatures is the primary cause of hurricanevariability," said Aslak Girnstead, a researcher with the Center for Ice and Climate at the University of Copenhagen. The large impact of small sea-surface temperature increases was more than Girustead and his colleagues had anticipated. The entire study was published in the Proceedings of the National Academy of Sciences.Global temperatures have steadily increased, making the past decade the warmest on record. Earlier this year, climate researchers reported that the Earth's temperatures have risen faster in the last century than at any point since the last ice age, 11,300 years ago. The primary cause, a couseusus of scientists has said, is the rising emissions of greenhouse gases like carbon dioxide and methane.Past hurricanes have supported the study's finding that global temperature rise is linked to more destructive storms. According to the National Center for Atmospheric Research, while the frequency of storms doesn't appear to have increased, the percentage of strong ones has risen sharply over the past few decades. The trend may be similar further back in time, but comprehensive hurricane data doesn't exist.61. According to the team of international researchers based at Beijing Normal University, the rise of the Earth'stemperature is likely to causeA.the coming of ice ageC.more Katrina-like or worse hurricanesB.less intense hurricanesD.more greenhouse gases in the atmosphere62. The ocean water in the region where the storm formsA.is heating the hurricanesB.evaporates and becomes fuelC.heads toward landD.turns into water vapor that makes hurricanes stronger63. Which of the following statement is TRUE about Hurricane Katrina?A.It did not lose its strength as it moved.B.It claimed over 200 people's lives.C.It caused 80 billion dollars loss for Florida peninsula.D.It lasted for full 24 hours.64. What result can regional sea surface temperature changes produce?A.Hurricane changes.C.Global warming.B.Increasing greenhouse gas emissions.D.Destructive hurricanes.65. It can be inferred from the passage thatA.there is no link between greenhouse gas emissions and destructive stormsB.reduction of greenhouse gas emissions may reduce destructive stormsC.the higher percentage of strong ones rose as more hurricanes appearedD.past records on hurricanes included everything needed 答案解析:56.A)。

六级英语阅读理解练习题1A controversy erupted in the scientific community in early 1998 over the use of DNA(deoxyribonucleic acid ) fingerprinting in criminal investigations. DNA fingerprinting wasintroduced in 1987 as a method to identify individuals based on a pattern seen in their DNA,the molecule of which genes are made. DNA is present in every cell of the body except redblood cells. DNA fingerprinting has been used successfully in various ways, such as todetermine paternity where it is not clear who the father of a particular child is. However, it isin the area of criminal investigations that DNA fingerprinting has potentially powerful andcontroversial uses.DNA fingerprinting and other DNA analysis techniques have revolutionized criminalinvestigations by giving investigators powerful new tools in the attempt to trove guilt, not justestablishinnocence. When used in criminal investigations, a DNA fingerprint pattern from asuspect is compared with a DNA fingerprint pattern obtained from such material as hairs orblood found at the scene of a crime. A match between the two DNA samples can be used asevidence to convict a suspect.The controversy in 1998 stemmed form a report published in December 1991 bypopulation geneticists Richard C. Lewontin of Harvard University in Cambridge, Mass., andDaniel L. Hartl called into question the methods to calculate how likely it is that a matchbetween two DNA fingerprints might occur by chance alone. In particular, they argued that thecurrent method cannot properly determine the likelihood that two DNA samples will matchbecause they came from the same individual rather than simply from two different individualswho are members of the same ethnic group. Lewontin and Hartl called for better surveys of DNApatterns methods are adequate. In response to their criticisms, population geneticists Ranajit Chakraborty of theUniversity of Texas in Dallas and Kenneth K.Kidd of Yale University in New Haven, Conn.,argued that enough data are already available to show that the methods currently being usedare adequate.

But noise is more than just a nuisance. It constitutes a real and presentdanger to peoples health. Day and night, at home, at work, and at play, noise can produceserious physical and psychological stress. No one is immune to this stress. Though we seemto adjust to noise by ignoring it, the ear, in fact, never closes and the body still responds—sometimes with extreme tension, as to a strange sound in the night.The annoyance we feel when faced with noise is the most common outward symptom ofthe stress building up inside us. Indeed, because irritability is so apparent, legislators havemade public annoyance the basis of many noise abatement programs. The more subtle andmore serious health hazards associated with stress caused by noise traditionally have beengiven much less attention. Nevertheless, when we are annoyed or made irritable by noise, weshould consider these symptoms fair warning that other thing may be happening to us, some ofwhich may be damaging to our health.Of many health hazards to noise, hearing loss is the most clearly observable andmeasurable by health professionals. The other hazardsare harder to pin down. For many of us,there may be a risk that exposure to the stress of noise increases susceptibility to diseaseand infection. The more susceptible among us may experience noise as a complicating factorin heart problems and other diseases. Noise that causes annoyance and irritability in healthpersons may have serious consequences for these already ill in mind or body. Noise affects us throughout our lives. For example, there are indications of effects on theunborn child when mothers are exposed to industrial and environmental noise. During infancyand childhood, youngsters exposed to high noise levels may have trouble falling asleep andobtaining necessary amounts of rest.Why, then, is there not greater alarm about these dangers? Perhaps it is because the linkbetween noise and many disabilities or diseases has not yet been conclusively demonstrated.Perhaps it is because we tend to dismiss annoyance as a price to pay for living in the modernworld. It may also be because we still think of hearing loss as only an occupational hazard.六级英语阅读理解练习题1.In Paragraph 1, the phrase "immune to" are used to mean ___.A.unaffected byB.hurt byC.unlikely to be seen byD.unknown by2.The authors attitude toward noise would best be described as ___.A.unrealisticB.traditionalC.concernedD.hysterical3.Which of the following best states the main idea of the passage?A.Noise is a major problem; most people recognize its importance.B.Although noise can be annoying, it is not a major problem.C.Noise is a major problem and has not yet been recognized as such.D.Noise is a major problem about which nothing can be done.4.The author condemns noise essentially because it ___.A.is against the lawB.can make some people irritableC.is a nuisanceD.in a ganger to peoples health5.The author would probably consider research about the effects noise has onpeople to be ___.A.unimportantB.impossible.C.a waste of moneyD.essential六级英语阅读理解练习题答案 ACCDD。

Pursuing a career is an essential part of adolescent development.“The adolescent becomes an adult when he_26_a real job.”To cognitive researchers like Piaget,adulthood meant the beginning of
an_27_.
Piaget argued that once adolescents enter the world of
work,their newly acquired ability to form hypotheses allows them to create representations that are too ideal.The_28_of such ideals,without the tempering of the reality of a job or profession,rapidly leads adolescents to become _29_ of the non-idealistic world and to press for reform in a characteristically adolescent way.Piaget said:“True adaptation to society comes_30_when the adolescent reformer attempts to put his ideas to work.”
Of course,youthful idealism is often courageous,and no one likes to give up dream s.Perhaps,taken_31_out of context,Piaget’s statement seems harsh.What he was_32_,however,is the way reality can modify idealistic views.Some people refer to such modification as
maturity.Piaget argued that attaining and accepting a vocation is one of the best ways to modify idealized views and to mature.
As careers and vocations become less available during times of _33_,adolescents may be especially hard hit.Such difficult economic times may leave many adolescents_34_about their roles in society.For

英语六级阅读理解解题技巧
一、事实细节题
识别:题目往往会以wh-疑问词(如what, who, which, when, where, why, how)提问。

常考考点:转折、因果、列举、指代等
破解技巧:事实细节题的解题关键在于定位。

建议考生先快速浏览题目并划出题干中的关键词,然后回原文找相应的关键词,进行段落定位,之后回到题目和选项,看哪个选项符合题干要求且与原文对应信息表述一致。

注意:正确选项往往是原文对应信息的同义转述,而照抄原文内容的选项往往是干扰项;除此之外,常见的干扰项还包括与原文描述相悖、与原文内容部分相符、原文没有提及的信息等。

二、推理判断题
识别:题干中含有infer, imply, learn from和 conclude等词。

常考考点:对细节、段落或全文进行推断
破解技巧:先扫读题干,判读题目要求是对细节、段落还是全文进行推断。

如果是对细节和段落进行推断,则后面的做法与事实细节题相同;如果要求对全文进行推断,则文章主题和中心思想是解题的主要依据,所以需要考生浏览全文掌握文章主题,正确答案往往是对原文描述的总结,或换个角度表述与原文相同的意义。

三、主旨大意题
识别:题干中含有the main idea, the best title和the main purpose of the passage等词。

破题技巧:该题型考查考生综合概括能力,需要先考生回到原文,重点关注首尾段和各段首尾句,这些句子一般为各段主题句,综合起来即可得出文章主旨;然后回到题目,排除干扰项(如文章局部信息、与原文无关信息以及与原文相悖选项等),挑出正确选项。

四、观点态度题
识别:题目中有opinion, attitude以及feel about等词。

常考考点:文中某人或作者的观点
破题技巧:如果题目考查文中某人的观点或作者对文中提及某一事物的观点,则需要考生利用题干关键词进行定位,解题方法与事实细节题相同。

但是,如果题目考查作者对全文主题的观点态度,则需要考生综合全文信息,体会作者在文章中的写作措辞和语气,进而得出作者的观点态度。

英语六级阅读理解的技巧
1 详略得当
对于大学英语四六级阅读来说,根据题目的“题眼”快速在文章中找到答案是最关键的,这样我们就要在阅读时注意详略得当。

克服精读精益求精的习惯,做到有信息处精读,无信息处略读,略读处一扫而过。

题目中数字、人名等信息(题眼)在原文中对应的部分必须详读。

而对所要解释或证明的观点的细节举例处或者通常有数个名词的.并列项,它们不是完整的主谓宾的句子,因此无法与问题对应的详细列举处,都可以略读。

2 显性信息
查读的信息通常是显性信息,只要将问题在原文中进行准确定位就能得到正确答案,一般不需要做推理。

特别提示:考生对于以下一些显性信息也应注意
(1) 表示因果关系的词或词组:because, reason, due to, since,so that, therefore等
(2) 表示目的关系的词或词组:in order to, so as to, by等
(3) 表示转折关系的词或词组:but, however, yet等
(4) 表示对比关系的词或词组:contrary to, unlike, like等
3 题文同序
英语四六级考试的阅读部分,问题顺序与原文顺序一致(有时顺序不一致),这就要求考生应该按照题目的顺序依次做题。

4 分解对应
分解对应四分法:快速将问题分解成4个部分(主A 谓B宾C+其他D),与原文进行对比。

5 选小不选大
四六级阅读中,问题的范围必须小于原文范围,反之则不选。

不能选的选项为:
(1) 选项的信息与原文内容相反
(2) 选项将原文的意思张冠李戴
(3) 将原文中的不确定因素转化为确定因素
(4) 改变原文中的条件、范围等。
