What is ozone? What does an orange alert mean? Why should you be concerned about it? In this article, we will examine what ozone is, how it is produced, what health hazards it poses and what you can do to reduce ozone pollution. B) Ozone is a molecule of three oxygen atoms bound together (O3). It is unstable and highly reactive. Ozone is used as a bleach, a deodorizing agent, and a sterilization agent for air and drinking water. At low concentrations, it is toxic. Ozone is found naturally in small concentrations in the stratosphere, a layer of Earth’s upper atmosphere. In this upper atmosphere, ozone is made when ultraviolet light from the sun splits an oxygen molecule (O2), forming two single oxygen atoms. If a freed atom collides with an oxygen molecule, it becomes ozone. Stratospheric ozone has been called “good” ozone because it protects the Earth’s surface from dangerous ultraviolet light. C) Ozone can also be found in the troposphere, the lowest layer of the atmosphere. Tropospheric ozone (often termed “bad ” ozone) is man - made, a result of air pollution from internal combustion engines and power plants. Automobile exhaust and industrial emissions release a family of nitrogen oxide gases (NOx) and volatile organic compounds (VOC), by-products of burning gasoline and coal. NOx and VOC combine chemically with oxygen to form ozone during sunny, high- temperature conditions of late spring, summer and early fall. High levels of ozone are usually formed in the heat of the afternoon and early evening, dissipating during the cooler nights. D) Although ozone pollution is formed mainly in urban and suburban areas, it ends up in rural areas as well, carried by prevailing winds or resulting from cars and trucks that travel into rural areas. Significant levels of ozone pollution can be detected in rural areas as far as 250 miles downwind from urban industrial zones. E) You can make ozone test strips to detect and monitor ozone levels in your own backyard or around your school. You will need corn starch, filter paper (coffee filters work well) and potassium iodide (can be ordered from a science education supplier such as Carolina Biological Supply or Fisher Scientific). Basically, you make a paste from water, corn starch and potassium-iodide, and you paint this paste on strips of filter paper. You then expose the strips to the air for eight hours. Ozone in the air will react with the potassium iodide to change the color of the strip. You will also need to know the relative humidity, which you can get from a newspaper, weather broadcast or home weather station. F) When you inhale ozone, it travels throughout your respiratory tract. Because ozone is very corrosive, it damages the bronchioles and alveoli in your lungs, air sacs that are important for gas exchange. Repeated exposure to ozone can inflame lung tissues and cause respiratory infections. G) Ozone exposure can aggravate existing respiratory conditions such as asthma, reduce your lung function and capacity for exercise and cause chest pains and coughing. Young children, adults who are active outdoors and people with respiratory diseases are most susceptible to the high levels of ozone encountered during the summer. In addition to effects on humans, the corrosive nature of ozone can damage plants and trees. High levels of ozone can destroy agricultural crops and forest vegetation. H) To protect yourself from ozone exposure, you should be aware of the Air Quality Index (AQI) in your area every day—you can usually find it in the newspaper or on a morning weather forecast on TV or radio. You should also be familiar with the U.S. Environmental Protection Agency (EPA) guide for ozone-alert values. I) What do the numbers in the AQI mean? The AQI measures concentrations of five air pollutants: ozone, sulfur dioxide, particulate matter, carbon monoxide and nitrogen dioxide. The EPA has chosen these pollutants as criteria pollutants, but these are not all of the pollutants in the air. These concentrations are compared to a standard set out in federal law. An index value of 100 means that all of the criteria pollutants are at the maximum level that is considered safe for the majority of the population. To reduce your exposure to ozone, you should avoid exercising during afternoon and early evening hours in the summer. J) There are several ways you can help to decrease ozone pollution. Limit using your automobile during afternoon and early evening hours in the late spring, summer and early fall. Do not use gasoline-powered lawn equipment during these times. Do not fuel your car during these times. Do not light fires or outdoor grills during these times. Keep the engine of your car or boat tuned. Make sure that your tires are properly inflated. Use environmentally safe paints, cleaning and office products (some of these chemicals are sources of VOC). K) Besides personal attempts to reduce ozone pollution, the EPA has initiated more stringent air-quality standards (such as the Clean Air Act and its modifications) to reduce air pollution. Compliance with these standards by industries, manufacturers and state and local governments has significantly reduced the levels of many common air pollutants. L) With continued conservation and reduction practices, adherence to ozone-pollution warnings, research and government regulation, ozone-pollution levels should continue to fall. Perhaps future generations will not be threatened by this environmental pollutant. M) The thing that determines whether ozone is good or bad is its location. Ozone is good，when it is in the stratosphere. The stratosphere is a layer of the atmosphere starting at the level of about 6 miles (about 10 kilometers) above sea level. The stratosphere naturally contains about six parts per million of ozone, and this ozone is very beneficial because it absorbs UV radiation and prevents it from reaching us. N) Ozone is “bad” when it is at ground level. Ozone is a very reactive gas that is hard on lung tissue. It also damages plants and buildings. Any ozone at ground level is a problem. Unfortunately, chemicals in car exhaust and chemicals produced by some industries react with light to produce lots of ozone at ground level. In cities, the ozone level can rise to a point where it becomes hazardous to our health. That’s when you hear about an ozone warning on the news. 1. When ultraviolet rays from the sun separate an oxygen molecule into two single oxygen atoms in the stratosphere, the combination of a single oxygen atom and an oxygen molec u l e f o r m s o z o n e . / p > p b d s f i d = " 1 2 6 " > 0 0 2 .

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.。

2020年六级长篇阅读练习及答案详解(3)

2020年六级长篇阅读练习及答案详解(3) Preparing for Computer DisastersA： Summary： When home office computers go down, many small businesses grind to a halt. Fortunately, taking stepsto recover from disasters and minimize their effects is quite straightforward.B： Fires, power surges, and floods, they're all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate over their bad luck. We also shake our heads atthe digital consequences—melted computers, system failures, destroyed data. Yet, somehow, many of us continue to live by that old mantra of denial： "It won't happen to me." Well,the truth is, at some point you'll probably have to deal with at least one disaster. That's just how it goes, and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disasterplans and run drills. But for some reason, computer disaster recovery is a blind spot for many of us. It shouldn't be. Home computers contain some of our most important information, both business and personal, and making certain our data survives a disaster should be a priority. Moreover, even the smallest disaster can be a serious disruption. Personal computers have become an integral part of the smooth-running household. We use them to communicate, shop, and do homework, and they're even more vital to home office users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. With a goodoffsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a major calamity strike, you can rest assured your data is safe.Offsite Storage： Major DisastersC： House fires and floods are among the most devastating causes of personal computer destruction. That's why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their house flood our burn. That's because they keep their backups 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 they're not nearly far enough away should a serious disaster strike. So, it's important to back up your system to a removable medium and to store it elsewhere.D： There are many ways to approach offsite storage. It starts with choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldn't add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in 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 backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.E： Once you select your tools and a suitable medium, you need 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, it's important to be prepared. As with physical disasters, regular backups are essential. However, some of these smaller issues require a responsethat's more nuanced than wholesale backup and restoration. To deal with less-than-total disaster, your tool set must be both powerful and agile. For example, when a small number of files are compromised, you may want to retrieve those files alone. Meanwhile, if just your settings are affected, you'll want a simple way to roll back to your preferred setup. Yet, should your operating system fail, you'll need a way to boot。

For questions 1-7, choose the best answer from the fourchoices marked A), B), C) and D). For questions 8-10, complete the sentences with theinformation given in the passage.There's a price to be paid for our cheap foodThe big food companies should be taxed for the damage they cause to our bodies and the planet The world is throwing away a shocking amount of food. A report last week claimed that at least a third of the 4 billion tonnes of food the world produces each year never gets as far as our mouths. Between 30% and 50% of food purchased in Europe and the US is thrown away. The research is questioned, not least by the supermarkets, but it does echo the results of an exercise in Britain six years ago, when researchers for the government-funded Waste and Resources Action Programme (Wrap) went through the nation's rubbish bins. It concluded that we were throwing away 30% of the food we'd bought while it was still edible (可食用的).Britain – and much of the rich world – has got used to filling the fridge with what looks nice, not what it actually needs. The cost of that indulgence (放纵) is, says the Institute of Mechanical Engineers, £10bn annually. Globally, the cost, in money, energy and ever-scarcer water, is unquantifiable.Our future food security has been climbing the top 10 of current global worries. The prospect of feeding a mid-century planet of around 9 billion people looks impossible without major and potentially unattractive changes to farming and our diet. If you accept the United Nations Food and Agricultural Organisation's call for production to be increased by 70% to feed the population of 2050, most of the work will be achieved just by being a bit more thrifty (节俭的). All we have to do is to use better what is already there.However, throwing food out is easy. Using it sensibly, especially the less attractive bits, is not. The urge to bin and buy again, encouraged by multimillion pound advertising campaigns, is all the less resistible now because, despite recent price rises, for most of us, food is cheap. At Christmas, the average family spent just over £100 on the big meal, a quarter of what it spent on presents. Stopping the waste will take more than a few celebrity chefs telling us how to use the roast chicken leftovers or asking the supermarkets to relax a bit with buy one, get one free offers.Education of consumers and voluntary agreements with the retail industry have all been tried: Wrap is 13 years old this year and has not impressed. Its critics say that its expensive information campaigns under slogans such as "Love Food Hate Waste" lack targets and convincingly audited (审计) results. Like so many toothless quangos(半官方机构), it can only cajole (利诱) business rather than bring it firmly to heel. More households may be portion-planning and recycling now,because of Wrap's adverts, but the slight reduction in the tonnage of food estimated to have been thrown away in British households (from 8.3m in 2006/07 to 7.2m in 2010) is probably accounted for by the price rises and stall in incomes that followed the global economic crash of 2008.Here we come to the uncomfortable core of the problem. Price is the key factor in our behaviour with food and food may, simply, be too cheap. Certainly, in Britain it is cheaper than at any time in history: we spend less than 10% of household income on food and drink. In 1950, we spent around 25%. In the developing world, 50% or more of income is spent on food. Tellingly, Britain spends less than any other country in Europe. Worldwide, it seems that the lower a country's food/income ratio, the higher its incidence of obesity(肥胖). Presumably, the higher also the proportion of food it chucks out.Observers of food policy certainly believe that cheap food is a problem or, as Professor Tim Lang of City University tells it, that too much of the true cost of food is born not by the consumer or the retailer. The environmental and health damage caused by modern food production and its transport, as well as by excessive consumption, entails vast costs, often picked up by people far away from Tesco's catchments. But it is the supermarkets' eternal price wars –their one-track marketing philosophy where "value" trumps all other qualities in food – that have driven prices so low. Without restoring a sense of the real value of food, how will we stop all but the hungry wasting it?Food inflation is a key political indicator, yet no government is going to risk price rises for all the good it might do for our health or our environment, let alone the chance of stopping the landfill. Supermarkets, with their powerful lobbying arms and political donations, habitually wriggle away from legislation and Competition Commission criticism merely with the threat that any new regulation will raise prices. That has to stop. A far tougher position is required.The government's promise to abolish the use of "sell by" and "display until" labels has been parlayed into voluntary Food Standards Agency "advice". Because of industry resistance, Wrap has never fully measured waste caused upstream from the household, even though the retailers and manufacturers are certainly to blame for more of the tonnage that goes to landfill. It may always be easier to blame the consumer but what is required is far stricter regulation of the food giants.So how could we regulate? Producers complain that the major supermarket chains enslave them in very harsh contracts that set up a damaging chain reaction. Producers then pay low wages, which are in turn subsidised by taxpayers via tax credits. These boost incomes that are still so low that families are forced to buy inferior food. (Supermarket chains –hugely profitable –also pay risibly low wages to workers.) Ending this vicious cycle is not simply about food pricing, it's a far larger debate. Even in austerity, the profits of the "big food" companies continue to rise. This isabout more than pricing – it's about a sense of responsibility about what's fair.An alternative to voluntary change is to tax the food industry in just proportion to the damage it causes. Another idea gaining ground across Europe is for a sugar tax – the cheap processed foods and soft drinks that carry the largest profit margins (and which are a key cause of obesity) depend hugely on sugar for their appeal. Food price rises would result and the supermarkets' vast profits might have to take a hit. Those who would really suffer are the poor and their children and that is a challenge to be met fairly with a living wage, not by caps on benefits or food banks.There are lots of ideas around for the "zero-waste economy" that successive governments have repeatedly promised. But first and foremost, politicians have to conquer their fear of "big food".1. What did a research reveal last week?A) Nearly half of the food purchased is not edible.B) More than a third of the food is thrown away.C) There is a disguised increase in the food price.D) British households waste most food in the world.2. What does the author say about households in much of the rich world?A) They only purchase things to meet their basic needs.B) They have to spend more income on food and drinks.C) They are accustomed to buying food that looks nice.D) Few of them live a life of wealth and indulgence.3. According to the author, it is impossible to feed 9 billion people of 2050 unless ______.A) we make a fine adjustment to farmingB) the UN takes actions to curb wastingC) we now make big changes to our dietD) people accept genetically modified foods4. People find it hard to resist the urge to throw food away and buy again because ______.A) food is not expensive for themB) some food has a short shelf lifeC) the food price fluctuates sharplyD) there is an abundant supply of food5. What do we learn about Wrap’s information campaigns?A) They persuaded millions to be thrifty.B) They have achieved the original goals.C) They forced stores to give up free offers.D) They are criticized for lacking targets.6. Food waste was reduced slightly from 2010 to 2006 probably because of ______.A) the consumer educationB) Wrap’s advertisementsC) people’s recyclingD) the price increases7. What has driven food prices so low according to the author?A) The cheap raw materials imported.B) The supermarkets’ continuing price wars.C) The usage of intensive farming techniques.D) The poor consumer demand for food.8. The government is unwilling to __________________________ even though it might do the environment good.9.

Read the passage carefully. Then answer the questions or complete the statements in the fewestpossible words. Please write your answers on Answer Sheet 2.Questions 47 to 51 are based on the following passage.When students arrive on campus with their parents, both parties often assume that the school will function in loco parentis (代替父母), watching over its young charges, providing assistance when needed. Colleges and universities present themselves as supportive learning communities —as extended families, in a way. And indeed, for many students they become a home away from home. This is why graduates often use another Latin term, alma mater, meaning "nourishing mother." Ideally, the school nurtures its students, guiding them toward adulthood. Lifelong friendships are formed, teachers become mentors, and the academic experience is complemented by rich social interaction. For some students, however, the picture is less rosy. For a significant number, the challenges can become overwhelming.In reality, administrators at American colleges and universities are often obliged to focus as much on the generation of revenue as on the new generation of students. Public institutions in particular are often faced with tough choices about which student support services to fund, and how to manage such things as soaring health-care costs for faculty and staff. Private schools are feeling the pinch as well. Ironically, although tuition and fees can increase as much as 6.6 percent in a single year, the high cost of doing business at public and private institutions means that students are not necessarily receiving more support in return for increased tuition and fees. To compound the problem, students may bereluctant to seek help even when they desperately need it.Just as colleges are sometimes ill equipped to respond to the challenges being posed by today's students, so students themselves are sometimes ill equipped to respond to the challenges posed by college life. Although they arrive on campus with high expectations, some students struggle with chronic shyness or perfectionism, learning disabilities, addiction, or eating disorders. Still others may have an unreliable moral compass, and some go wild when they realize that the only real prohibition against things like alcohol, drugs, and sex is their own willpower. Most experience failed relationships; some suffer from acute loneliness, mental illness, or even rage.Unfortunately, higher education is sometimes more of an information delivery system than a responsive, collaborative process. We have created cities of youth in which students can pass through unnoticed, their voices rarely heard, their faces rarely seen. As class size grows in response to budget cuts, it becomes even less likely that troubled students, or even severely disturbed students, will be noticed. When they're not, the results can be tragic.47. Schools are expected to protect the students and _____________________ when their students need help.48. Both public and private schools have to focus on _____________________ besides looking aftertheir students.49. Students’ _____________________ to seek help may exaggerate sch ools’ inability to help them.50. S ome of today’s students are sometimes _____________________ in face of overwhelmingchallenges in college.51. Higher education should be responsive and _____________________ to avoid students beingrarely heard and seen during their college life.Section BDirections: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 Sheet2 with a single line through the centre.Passage OneQuestions 52 to 56 are based on the following passage.Higher education institutions are predictably cool to President Obama’s proposal to shift fe deral aid away from colleges that fail to control rising tuition. Even though the details of his plan, which would require Congressional approval, will not be fleshed out until later this month, the idea behind it is sound.The federal government must do more to rein in tuition costs at the public colleges that educate more than 70 percent of the nation’s students. By one estimate, the cost of four-year public college tuition has tripled since the 1980s, outpacing both inflation and family income. The increase in the tuition burden is largely caused by declining state support for higher education in the past three decades. In both good times and bad, state governments have pushed more of the costs onto students, forcing many to take out big loans or be priced out of once affordable public colleges at a time when a college education is critical in the new economy.While financial aid is available to some low-income students, many are driven away by tuition sticker shock. At the same time, many colleges have failed to find more cost-effective ways to deliver education and get the average student to graduation in four years. President Obama was on the mark when he said that this needs to change.An analysis by State Higher Education Executive Officers, a nonprofit group, shows clearly what has happened in public higher education since 1985. In Michigan, for example, the net tuition paid per student after financial aid rose from about $3,900 in 1985 to nearly $9,000 in 2010, in inflation adjusted dollars. In response, students have turned to loans. In the last decade, federal college loan debt has more than doubled from $41 million to $103 million, according to the College Board.President Obama’s proposed reform plan would require colleges that receive federal aid to create ―a scoreboard‖ that gives actual costs, graduation rates and potential earnings for graduates. His idea for establishing a $1 billion fund to provide grants to states that improve graduation rates and reduce costs is a good one. He also calls for expanding campus-based aid — mainly loans and work-study programs —to more than $10 billion from the current $2.7 billion. And, for the first time, the government would punish colleges that failed to control tuition or that did not provide good value by shifting money to other schools that do a better job.Determining what amounts to good value will be difficult, and persuading Congress to move forward on any of these ideas will be hard. But Mr. Obama is right that the federal government should begin leveraging (利用) its sizable investment in higher education for reform.52. Obama’s proposal about federal aid intends to ______.A) impel colleges to attach importance to their finance managementB) withdraw federal aid from collegesC) urge colleges to bring down the tuition costsD) reduce the number of colleges53. What mainly led to the rising of students’ tuition burden in the past three decades?A) The lack of state support.B) The higher inflation.C) The shrinking of family income.D) The weakening of loan support.54. The analysis by State Higher Education Executive Officers further shows that ______.A) financial aid doesn’t efficiently help poor students receive higher educationB) the development of higher education lags behind the growth of economyC) the tuition has been going up faster than inflationD) higher education institutions are turning into profit-making organizations55. The initiative of Obama’s reform plan is reflected in ______.A) increasing the funding in educationB) creating campus-based aidC) making the use of federal aid transparentD) linking federal aid to the value provided by colleges56. What’s the author’s attitude towards Obama’s reform plan?A) Positive. B) Negative. C) Skeptical. D) Indifferent.Passage TwoQuestions 57 to 61 are based on the following passage.Compared with elderly parents and adult children in five other industrialized nations, Americans are twice as likely to have ―disharmonious‖ relationships, a new multinational study has found. And we’re correspondingly less likely to have ―friendly‖ relationships marked by strong affection and relatively free of conflict. The study of nearly 2,700 parents over age 65, published recently in The Journal of Marriage and Family, turned up significant national differences. German and Spanish parents described relationships with their adult children as more detached. The English reported the most friendly families. Israelis operated with a high degree of ambivalence (正反感情并存), meaning they indicated strong positive and negative emotions. Norwegians placed somewhere in the middle.。

2020年大学英语六级考试阅读冲刺模拟训练(3)Scholars and students have always been great travelers. The official case for “academic mobility” is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold.Mobility of this kind meant also mobility of ideas, their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have no interest in being credited with a starling discovery, or a new technique. It must also have been reassuring to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect.In the twentieth century, and particularly in the last 20 years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aeroplane, making contact between scholars even in the most distant places immediately feasible, and providing for the very rapid transmission of knowledge.Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention： there are far more centres of learning, and a far greater number of scholars and students.In addition one must recognize the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests are precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries.Questions 1 to 5 are based on the passage above.1.It can be concluded from the passage that"academic mobility"_____.A.means the friendship formed by scholars on the tripB.is a program initiated by governmentsC.has been put great emphasis on in the worldD.means going abroad in search of the best teacher2.The word "eccentric" in the second paragraph most probably means_____.A.a rather strange personB.a person of no exceptional abilityC.an ambitious personD.peculiar or unusual3.In the eyes of the author,what happens to a scholar who shares his ideas with his colleagues?A.He risks his ideas being stolen.B.He gains recognition for his achievementC.He is considered as an eccentric.D.He is credited with a startling discovery.4.According to the passage,the recent growth in airtravel has meant that_____.A.travel around the world becomes realistic and affordableB.more students from remote areas can attend universitiesC.all kinds of information can be shared by more peopleD.scholars can meet each other more easily5.The author thinks that it's important for scholars to be able to travel because_____.A.their laboratories ate in remote placesB.there is too much stress at universitiesC.their fellow experts are scattered around the worldD.there are so many people working in similar fields文章摘要议论文。

2020年大学英语六级阅读理解预测题及答案(3)

2020年大学英语六级阅读理解预测题及答案(3)The "standard of living" of any country means the average person's share of the goods and services which the country produces. A country's standard of living, therefore, depends first and foremost on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy： "goods" such as food and clothing, and "services" such as transport and entertainment.A country's capacity to produce wealth depends upon many factors, most of which have an effect on one another. Wealth depends to a great extent upon a country's natural resources, such as coal, gold, and other minerals, water supply and so on. Some regions of the world are well supplied with coal and minerals, and have a fertile soil and a favorable climate; other regions possess perhaps only one of these things, and some regions possess none of them. The U. S. A is one of the wealthiest regions of the world because she has vast natural resources within her borders, her soil is fertile, and her climate is varied. The Sahara Desert, on the other hand, is one of the least wealthy.Next to natural resources comes the ability to turn them to use. China is perhaps as well off as the U. S. A. in natural resources, but suffered for many years from civil and external wars, and for this and other reasons was. unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasion, enable a country to develop its natural resources peacefully and steadily, and to produce more wealth than another country equally well servedby nature but less well ordered. Another important factor is the technical efficiency of a country's people. Old countries that have, through many centuries, trained up numerousskilled craftsmen and technicians are better placed to produce wealth than countries whose workers are largely unskilled. Wealth also produces wealth. As a country becomes wealthier, its people have a large margin for saving, and can put their savings into factories and machines which will help workers to turn out more goods in their working day.1. A country's wealth depends upon______. ,A. its standard of livingB. its moneyC. its ability to provide goods and servicesD. its ability to provide transport and entertainment2. The word "foremost" means______.A. most importantlyB. firstlyC. largelyD. for the most part3. The main idea of the second paragraph is that______.A. a country's wealth depends on many factorsB. the U. S. A. is one of the wealthiest countries in the worldC. the Sahara Desert is a very poor regionD. natural resources are an important factor in the wealth or poverty of a country4. The third paragraph mentions some of the advantages which one country may have over another in making use of its resources. How many such advantages are mentioned in this paragraph?A. 2B. 3C. 4D. 5参考答案：1. C 2. A 3. A 4. B。

全国英语六级考试阅读临考冲刺题全国英语六级考试阅读临考冲刺题Cunning proceeds from want of capacity.以下是店铺为大家搜索整理的全国英语六级考试阅读临考冲刺题，希望能给大家带来帮助!We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist (免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could mot. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don’t develop sleep disturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can control. Such findings reinforce psychologists’ suspicions that the experience or perception of helplessness is one of the most harmful factors in depression.One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975psychologist Robert Ader at the University of Rochester School of Medicine conditioned (使形成条件反射) mice to avoid saccharin (糖精) by simultaneously feeding them the sweetener and injecting them with a drug that while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader reexposed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlier conditioning died. He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.11. Laudenslager’s experiment showed that the immune system of those rats who could turn off the electricity ________.A) was strengthenedB) was not affectedC) was alteredD) was weakened12. According to the passage, the experience of helplessness causes rats to ________.A) try to control unpleasant stimuliB) turn off the electricityC) behave passively in controllable situationsD) become abnormally suspicious13. The reason why the mice in Ader’s experiment avoided saccharin was that ________.A) they disliked its tasteB) it affected their immune systemsC) it led to stomach painsD) they associated it with stomachaches14. The passage tells us that the most probable reason for the death of the mice in Ader’s experiment was that ________.A) they had been weakened psychologically by the saccharinB) the sweetener was poisonous to themC) their immune systems had been altered by the mindD) they had taken too much sweetener during earlier conditioning15. It can be concluded from the passage that the immune systems of animals ________.A) can be weakened by conditioningB) can be suppressed by drug injectionsC) can be affected by frequent doses of saccharinD) can be altered by electric shocks参考答案：BCDCA。

2020年英语六级长篇阅读冲刺练习及解析(3)Preparing for Computer DisastersA： Summary： When home office computers go down, many small businesses grind to a halt. Fortunately, taking stepsto recover from disasters and minimize their effects is quite straightforward.B： Fires, power surges, and floods, they're all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate over their bad luck. We also shake our heads atthe digital consequences—melted computers, system failures, destroyed data. Yet, somehow, many of us continue to live by that old mantra of denial： "It won't happen to me." Well,the truth is, at some point you'll probably have to deal with at least one disaster. That's just how it goes, and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disasterplans and run drills. But for some reason, computer disaster recovery is a blind spot for many of us. It shouldn't be. Home computers contain some of our most important information, both business and personal, and making certain our data survives a disaster should be a priority. Moreover, even the smallest disaster can be a serious disruption. Personal computers have become an integral part of the smooth-running household. We use them to communicate, shop, and do homework, and they're even more vital to home office users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. With a goodoffsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a major calamity strike, you can rest assured your data is safe.Offsite Storage： Major DisastersC： House fires and floods are among the most devastating causes of personal computer destruction. That's why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their house flood our burn. That's because they keep their backups 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 they're not nearly far enough away should a serious disaster strike. So, it's important to back up your system to a removable medium and to store it elsewhere.D： There are many ways to approach offsite storage. It starts with choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldn't add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in 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 backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.E： Once you select your tools and a suitable medium, you need 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, it's important to be prepared. As with physical disasters, regular backups are essential. However, some of these smaller issues require a responsethat's more nuanced than wholesale backup and restoration. To deal with less-than-total disaster, your tool set must be both powerful and agile. For example, when a small number of files are compromised, you may want to retrieve those files alone. Meanwhile, if just your settings are affected, you'll want a simple way to roll back to your preferred setup. Yet, should your operating system fail, you'll need a way to boot。

It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods.

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，下面是给大家提供的阅读理解范文供参考，以下是小编给大家整理的英语六级长篇阅读真题-3，希望可以帮到大家who's 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. it's a common complaint these days. Asteady stream of similar headlines accuse the net and its offspring apps, socialmedia sites and online games of addicting us to distractionB. There's little doubt that nearly everyone who comes in contact with the nethas difficulty concentration than it takes to post a status update. as one person ironically put it in the comments section of Schwartz's online article, "As I wasreading this very excellent article.I stopped at least half a dozen times to cheek my email.C.There's something different about this technology: it is both invasive and persuasive. but who's at fault for its overuse? To find solutions, it's important to understand what we’re 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 is doing 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 can't 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.It’s no winder these companies employ teams of people focused on engineering their services to be as engaging as possible. these products aren't habit-forming by chance; it's by design. they have an incentiveto keep us hooked.F.However, as good as these services are, there are simple steps we can taketo 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 notification setlings--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 it's 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 couldn't 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 the day--we're obsessed, but why? Because that's what the boss wants.For almost all white-collar jobs, A slow Response 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. there's 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 don’t 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 one's 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 to do 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 (or overusing )these gadgets. but there's 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.I'm online far more than I'd 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. that's when i discovered an uncomfortable truth. i use technology as an escape. when I'm doing something I'd rather not do, or when I'm someplace I'd 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-called"research. "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.it's easy to blame technology for being so distracting, but distraction is nothing new. Ar istotle and Socrates dehated nature of “akrasia”--our tendency to do things agninst our interests. If we're honest with ourselves, tech is just another way to occupy our time and minds,if we weren’t on our devices. We’d likely do similarly unproductive.N.personal technology is indeed more engaging than ever, and there's 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. that's not necessarily a problem, that's progress.O.These improvements don't mean we shouldn't attempt to control our use of technology. In order to make sure it doesn't control us, we should come to terms with the fact that it's mor e than the technology itself that’s 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 it is 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.

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. The Great Charter TryoutA． Long before Sci Academy, a charter school in New Orleans, had graduated its first senior class, the school was being heaped with accolades ( 称赞). In September 2020, when Sci Academy was just two years old, its 200 excited students--then all freshmen and sophomores--filed into Greater St. Stephen Baptist church, next door to the school. Together with local dignitaries ( 显要人物 ), journalists, and a brass band, the students watched on huge screens as the leaders of six charter schools from around the country appeared on The Oprah Winfrey Show. At the end of the show, they watched as Oprah handed each charter-school leader—including Ben Marcovitz, Sci Academy's founder—a $1 million check.B． Sci Academy is a flagship charter school and a model of the new data-driven, business-infused approach to education that has won its worship in New Orleans. After Hurricane Katrina in 2005, education reformers swept awaywhat remained of the traditional public schools in what had been one of the nation's lowest- performing districts. In their place, charters promised choice and increased accountability( 负责制 ). More than 75 percent of New Orleans kids landed in schools controlled by the so-called Recovery School District, which was heavily dominated by charter schools.C． "This transformation of the New Orleans educational system may turn out to be the most significant national development in education since desegregation," wrote Neerav Kingsland, the CEO of New Schools for New Orleans, the city's leading venture-philanthropy group incubating local charter schools, a year ago. "New Orleans students have access to educational opportunities that are far superior to any in recent memory."D． But eight years after Hurricane Katrina, there is evidence that the picture is far more complicated. Seventy- nine percent of RSD charters are still rated D or F by the Louisiana Department of Education. Sci is one of two RSD high schools to earn a B; there are no A-rated open-admission schools. In a school system with about 42,000 mostly poor African-American kids, every year thousands are out of school at any given time-- because they are on suspension, have dropped out, or are incarcerated. Even at successful schools, such as the highly regarded Sci Academy, large numbers of students never make it to graduation, and others are unlikely to make it through college.E． Figuring out what has taken place in the New Orleans schools is not just a matter of interest to local residents.From cities like New York to towns like Muskegon Heights, Michigan, market-style reforms have been widely considered as the answer to America's educational woes. New Orleans tellsus a lot about what these reforms look like in practice. And the current reality of the city's schools should be enough to give pause to even the most passionate charter supporters.F． With its chain-link fence and campus of module-like buildings--the result of a continuing post-Hurricane Katrina building shortage--Sci Academy doesn't look much like a model school. Freshmen, wearing the polo shirts and khakis of the school uniform, are required to walk along straight red lines that snake through the school's breezeways. Placards bearing slogans, such as "No Short Cuts; No Excuses" and "Go Aboveand Beyond," hang overhead.G． Everything at Sci Academy is carefully designed to maintain discipline and focus on the school's principal mission, which is to get every student into college. Each morning, at 8 a.m., the teachers, almost all white and intheir 20s, gather for a rousing thigh-slapping, hand-clapping, rap-chanting staff revival meeting, the beginning of whatwill be, for most, a 14- to 16-hour workday. Students arrivea half hour later, and if asked "Why are you here?" and "What will it take?" are expected to respond "To learn" followed by a recitation of the school's six core values： "achievement, respect, responsibility, perseverance, teamwork, and enthusiasm."H． Both curriculum and behavior are elaborately arranged. As kids file into class, a teacher hands them their "entry ticket," a survey that helps determine how much studentsretained from the previous class. An "exit ticket"distributed at the end of each class establishes how much kids have absorbed. Information from the exit tickets, as well as attendance, demerits for bad behavior, and "Sci bucks" for good behavior, are keyed into the Sci software system by teachers every night to help monitor both student and teacher performance.I． After the storm, the state fired the city's unionized teachers, who were mostly middle-aged African- Americans, an action that has been challenged in court. While a few schools have hired back teachers who worked in the pre-Katrina schools, the city now relies heavily on inexperienced educators--mostly young, white, and from out of town--who are willing, at least in the short run, to put in exhausting hours. But at many schools, including Sci Academy, plenty of teachers last for less than two years.J． In New Orleans, teachers with certifications from Teach for America number close to 400, five times the level a few years ago. Within the RSD, in 2020, 42 percent of teachers had less than three years of experience; 22 percent have spent just one year or less in the classroom, according to "The State of Public Education in New Orleans," a 2020 report by the pro-charter Cowen Institute at Tulane University.K． In part to help with this lack of experience, charter schools train teachers in highly regimented routines that help them keep control of their classrooms. The city's charter-school advocates argue that in the aftermath of the storm, when charter operators had to scale up quickly, theyneeded to start with basics： first order and security, then skill building. "Kids expect high school to be dangerous. They come to school with their backs up," explains Sci Academy's Marcovitz, a graduate of the elite Maret school in Washington, D.C., and Yale University. He says the routines--which are borrowed from methods pioneered by KIPP, a national charter chain that also operates schools in New Orleans--are intended to keep students focused and feeling safe.L． In one English class last fall, a teacher who had been at Sci for about a year held forth on the fine points of grammar, including the subtle difference between modal and auxiliary verbs. As a few heads drifted downward, she employed a popular charter-school management routine to hold the class's attention. "SPARK check! " she called. The acronym stands for sit straight; pencil to paper (or place hands folded in front); ask and answer questions; respect; and keep tracking the speaker.M． "Heads up, sit straight--15 seconds to go," she said, trying to get her students' attention. "All scholars please raise your homework in THREE, TWO, ONE. We need to set a goal around homework completion. I only see about one third complete homework."N． It's a long way from the city's charter school roots. In the 1990s, the city's first charter school, New Orleans Charter Middle School, was built on a progressive curriculum that used experiential projects and electives, such asbicycle repair and African dance, to foster a love of learning. The school became the most highly rated nonselective school in the city before it was devastatedduring Hurricane Katrina. But while its founders went on to create FirstLine, now one of the leading charter operators in New Orleans, the progressive roots of the charter movement have been swamped by the new realities of a competitive charter marketplace.O． Now, driven by both government policy and charitable funding--which rewards schools for preparing students for college and penalizes those that don't--most charter high schools in New Orleans describe themselves as "college prep." This may seem an admirable goal. But in a school system where the number of eighth graders who passed the end-of-course tests required to get into high school has, according to the Cowen Institute, virtually stagnated at about 60 percent, the push toward college leaves behind many of the most disadvantaged kids, who already face enormous hurdles because of poverty, parental abandonment, and one of the highest rates of gun violence in the nation. For some of these students, college is not necessarily a realistic goal.46. Teachers in charter schools are trained in strict and rigid ways since most of them are inexperienced.47. Instead of carrying on its tradition of being advanced, New Orleans Charter Middle School has to follow market rules to survive and compete with other schools.48. Students in New Orleans have got the best education opportunity they have ever had in recent years.49. Many charter high schools in New Orleans are to help students enter college, which is supported by government policy and attracts funds.50. Traditional public schools have been completely reformed in areas with worst reputation on education quality in 2005.51. Even schools like Sci Academy cannot keep teachers for long.52. Several years ago, there were only about 80 teachers with qualified certifications in New Orleans.53.Even Sci Academy, which enjoys a high reputation, fails to help a lot of students graduate.54. Various information on students can be tracked down in Sci Academy's computer systems to ensure the teaching quality.55. To solve the problem of American education, many people turn to the function of market as the key.更多推荐：。

In fact, one in four workers is dissatisfied with their current job, according to the recent “Plans for 2004 ”survey. Their career path may be financially rewarding, but it doesn 't meet their emotional, social or creative needs. They're stuck, unhappy, and have no idea what to do about it, except move to another job.Mary Lyn Miller, veteran career consultant and founder of the Life and Career Clinic, says that when most people are unhappy abouttheir work, their first thought is to get a different job. Instead, Miller suggests looking at the possibility of a different life. Through her book, 8 Myths of Making a Living, as well as workshops, seminars and personal coaching and consulting, she has helped thousands of dissatisfied workers reassess life and work.Like the way of Zen, which includes understanding of oneself as one really is, Miller encourages job seekers and those dissatisfied with work or life to examine their beliefs about work and recognize that “in many cases your beliefsare what brought you to where you are today. ” You may have been raised to think that women were best at nurturing and caring and, therefore, should be teachers and nurses. So that 's what you did. Or, perhaps you were brought up to believe that you should do what your father did, so you have taken over the family business, or become a dentist “justlike dad. ” If this sounds familiar, it 's probably time tolook at the new possibilities for your future.Miller developed a 7-step process to help potential job seekers assess their current situation and beliefs, identify their real passion, and start on a journey that allows them to pursue their passion through work.Step 1 ： Willingness to do something different.Breaking the cycle of doing what you have always done is one of the most difficult tasks for job seekers. Many find it difficult to steer away from a career path or make a change, even if it doesn 't feel right. Miller urges job seekers to open their minds to other possibilities beyond what they are currently doing.Step 2 ： Commitment to being who you are, not who or what someone wants you to be.Look at the \gifts and talents you have and make a commitment to pursue those things that you love most. If you love the social aspects of your job, but are stuck inside an office or “chained to your desk ” most of the time, vow to follow your instinct and investigate alternative careers and work that allow you more time to interact with others. Dawn worked as a manager for a large retail clothing store for several years. Though she had advanced within the company, she felt frustrated and longed to be involved with nature and the outdoors. She decided to go to school nights and weekends to pursue her true passion by earning her master 's degree in forestry. She now works in the biotech forestry division of a major paper company.Step 3 ： Self-definitionMiller suggests that once job seekers know who they are, they need to know how to sell themselves. “In the job market, you are a product. And just like a product, you most know the features and benefits that you have to offer a potential client, or employer. ” Examine the skills and knowledge thatyou have identify how they can apply to your desired occupation. Your qualities will exhibit to employers why they should hire you over other candidates.Step 4 ： Attain a level of self-honoring.Self-honoring or self-love may seem like an odd step for job hunters, but being able to accept yourself, without judgment, helps eliminate insecurities and will make you more self-assured. By acce pti ng who you are — all your emotio ns, hopes and dreams, your personality, and your unique way of being - you' ll p roject more con fide nee whe n n etwork ing and talking with potential employers. The power of self-honoring can help to break all the falsehoods you were programmed to believe - those that made you feel that you were not good enough, or strong enough, or intelligent enough to do what you truly desire.Step 5 ： Vision.Miller suggests that job seekers develop a vision that embraces the answer to “What do I really want to do?” one should create a solid statement in a dozen or so sentencesthat describe in detail how they see their life related to work. For instance, the secretary who longs to be an actress describes a life that allows her to express her love of Shakespeare on stage. A real estate agent, attracted to his current job because her loves fixing up old homes, describes buying properties that need a little tender loving care to make them more saleable.Step 6 ： Appropriate risk.Some philosophers believe that the way to enlightenment comes through facing obstacles and difficulties. Once people discover their passion, many are too scared to do anything about it. Instead, they do nothing. With this step, job seekers should assess what they are willing to give up, or risk, in pursuit of their dream. For one working mom, that meant taking night classes to learn new computer-aided design skills, while still earning a salary and keeping her day job.For someone else, it may mean quitting his or her job, taking out loan and going back to school full time. You 'll move one step closer to your ideal work life if you identify how much risk you are willing to take and the sacrifices you are willing to make.Step 7 ： Action.Some teachers of philosophy describe action in this way, “If one wants to get to the top of a mountain, just sitting at the foot thinking about it will not bring one there. It is by making theeffort of climbing up the mountain, step by step, that eventu ally the summit is reached. ” All too often,it is the lack of action that ultimately holds people back from attaining their ideals. Creating a plan and taking it one step at a time can lead to new and different job opportunities. Job-hunting tasks gain added meaning as you sense their importance in your quest for a more meaningful work life. The plan can include researching industries and occupations, talking to people who are in your desired area of work, taking classes, or accepting volunteer work in your targeted field.Each of these steps will lead you on a journey to a happier and more rewarding work life. After all, it is the journey, not the destination, that is most important.1. According to the recent “Plans for 2004 ” survey,most people are unhappy with their current jobs.2.

英语六级冲刺阅读训练及答案篇.docx

一The Earth comprises three principal layers: the dense, iron-rich core, the mantle made of silicate (硅酸盐) that are semi-molten at depth, and the thin, solid-surface crust There are two kinds of crust, a lowerand denser oceanic crust and an upper ， lighter continental crust found over only about 40 percent ofthe Earth's surface. The rocks of the crust are of very different ages. Some continental rocks are over3,000 million years old, while those of the ocean floor are less than 200 million years old. The crustsand the top, solid part of the mantle, totaling about 70 to 100 kilometers in thickness, at present appearto consist of about 15 rigid plates, 7 of which are very large. These plates move over the semi-moltenlower mantleto produce all of the major topographical( 地形学的 )features of the Earth. Active zoneswhere intense deformation occur are confined to the narrow, interconnecting boundaries of contact ofthe plates.There are three main types of zones of contact: spreading contacts where plates move apart, converging contacts where plates move towards each other, and transform contacts where plates slidepast each other. Newoceanic crust is formed along one or more margins of each plate by materialissuing from deeper layers of the Earth' s crust, for example, by volcanic eruptions (爆发) of lava (火山熔岩 ) at mid-ocean ridges. If at such a spreading contact the two plates support continents， a rift(裂缝)is formed that will gradually widen and become flooded by the tea. The Atlantic Ocean formed likethis as the American and Afro-European plates moved in opposite directions. When two platescarrying continents collide, the continental blocks,too light to be drawn down, continue to float and therefore buckle ( 起褶皱 ) to form a mountain chain along the length of the margin of the plates.练习题：Choose correct answers to the question:1.The Earth ’ s crust______.A.can be classified into two typesB.is formed along the margins of the platesC.consists of semi-molten rocksD.is about 70 to 100 kilometers thick2.The 15 plates of the Earth are formed from ___.A.the oceanic crusts and continental crustsB.the crusts and the mantleC.the crusts and the top and solid part of the mantleD.the continental crusts and the solid part of the mantle3.Seriously-deformed zones appear _______A.whenever the crusts move over mantleB.when the plates move towards each otherC.in the narrow boundaries where two plates meetD.to be the major topographical feature of the Earth4.According to the second paragraph, the formation of the Atlantic Ocean is theexample of_______.A.spreading contactsB.the influence of volcanic eruptionsC.converging contactsD.transform contacts5.This passage is probably_______.A.a newspaper advertisementB.a chapter of a novelC.an excerpt from a textbookD.a scientific report of new findings二A remarkable variety of insects live in this planet More species of insects exist than all other animal species together. Insects have survived on earth for more than 300 million years,and may possess the ability to survive for millions more.Insects can be found almost everywhere -- on the highest mountains and on the bottom of rushing streams, in the cold South Pole and in bubbling hot springs. They dig through the ground, jump and sing in the trees,and run and dance in the air. They come in many different colors and various shapes. Insects are extremely useful to humans, pollinating ( 授粉 )our crops as well as flowers in meadows, forests, deserts and other areas. But licks and some insects, such as mosquitoes and fleas, can transmit disease.There are many reasons why insects are so successful at surviving. Their amazing ability to adapt permits them to live in extreme ranges of temperatures and environments. The one place they have not yet been found to any major extent is in the open oceans. Insects can survive on a wide range, of natural and artificial foods —paint, pepper, glue, books, grain, cotton ， other insects, plants and animals Because they are small they can hide in tiny spaces.A strong, hard but flexible shell covers their soft organs and is resistant to chemicals, water and physical impact. Their wings give them the option of flying away from dangerous situations or toward food or males. Also, insects have an enormous reproductive capacity: An African ant queencan lay as many as 43,000 eggs a day.Another reason for their success is the strategy of protective color. An insect may be right before our eyes, but nearly invisible because it is cleverly disguised like a green leaf, lump of brown soil, gray lichen ( 青苔 ),a seed or some other natural object Some insects use bright, bold colors to send warning signals that they taste bad,sting or are poison.Others have wing patterns that look like the eyes of a huge predator, bitter-tasting insects; hungry enemies are fooled into avoiding them.练习题：Choose correct answers to the question:1.Insects can be found in large amounts in the following places EXCEPT _____.A.on the mountains with little airB.in the cold polar areasC.in the hot desert areasD.in the open oceans2.Insects protect themselves from chemicals by _______A.hiding in tiny spacesB.having a strong shellC.flying away when necessaryD.changing colors or shapes3.Some insects disguise like natural objects so as to ______A.frighten away their enemiesB.avoid being discoveredC.send warning signalsD.look bitter-tasting4.The passage mentions that insects ______.A.can be found in any extreme environmentsB.have survived longer than any other creaturesC.can be fed on any natural or man-made foodsD.are important for the growth of crops and flowers5.The passage is mainly about ______A.how insects survive in different placesB.why insects can survive so successfullyC.what insects can do to the environmentD.where insects can be found in quantity三The fridge is considered necessary. It has been so since the 1960s when packaged food list appeared with the label: "Store in the refrigerator."In my fridge less Fifties childhood, 1 was fed well and healthy. The milkman came every day, the grocer, the butcher ( 肉商 ), the baker, and the ice-cream man delivered two or three times each week. The Sunday meat would last until Wednesday and surplus(剩余的) bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on food deliveries have ceased, fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. Many well-tried techniques already existed -- natural cooling, drying, smoking, salting, sugaring, bottling...What refrigeration did promote was marketing --- marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the world in search of a good price.Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the rich countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house -- while outside, nature provides the desired temperature free of charge.The fridge's effect upon the environment has been evident, while its contribution to human happiness has been not important. If you don't believe me, try it yourself, invest in a food cabinet and mm off your fridge next winter. You may not eat the hamburgers( 汉堡包 ), but at least you'll get rid of that terrible hum.练习题：Choose correct answers to the question:1.The statement "In my fridgeless fifties childhood, I was fed well and healthily." suggests that______.A.the author was well-fed and healthy even without a fridge in his fifties.B.the author was not accustomed to fridges even in his fifties.C.there was no fridge in the author's home in the 1950s.D.the fridge was in its early stage of development in the 1950s.2.Why does the author say that nothing was wasted before the invention of fridges?A.People would not buy more food than was necessary.B.Food was delivered to people two or three times a week.C.Food was sold fresh and did not get rotten easily.D.People had effective ways to preserve their food.3.Who benefited the least from fridges according to the author?A.Inventors.B.Consumers.C.Manufacturers.D.Travelling salesmen.4.Which of the following phrases in the fifth paragraph indicates the fridge's negative effect on the environment?5.What is the author's overall attitude toward fridges?A.Neutral.B.Critical.C.Objective.promising.四Moreover, insofar as any interpretation of its author can be made from the five or six plays attributed to him, the Wake field Master is uniformly considered to be a man of sharp contemporary observation. He was, formally, perhaps clerically educated, as his Latin and music, his Biblical and patristic lore indicate. He is, still, celebrated mainly for his quick sympathy for the oppressed and forgotten man, his sharp eye for character, a ready ear for colloquial vernacular turns of speech and a humor alternately rude and boisterous, coarse and happy. Hence despite his conscious artistry as manifest in his feeling for intricate metrical and stanza forms, he is looked upon as a kind of medieval Steinbeck, indignantly angry at, uncompromisingly and even brutally realistic in presenting the plightof the agricultural poor.Thus taking the play and the author together, it is mow fairly conventional to regard the former as a kind of ultimate point in the secularization of the medieval drama. Hence much emphasison it as depicting realistically humble manners and pastoral life in the bleak hills of the West Riding of Yorkshire on a typically cold bight of December 24th. After what are often regarded as almost “documentaries ” given in the three successive monologues of the three shepherds, critics go on to affirm that the realism is then intensified into a burlesque mock-treatment of the Nativity. Finally as asort of epilogue or after-thought in deference to the Biblical origins of the materials, the play slidesback into an atavistic mood of early innocent reverence. Actually, as we shall see, the final scene isnot only the culminating scene but perhaps the raisond ’ etre of introductory “ realism. ”There is much on the surface of the present play to support the conventional view of itsmood of secular realism. All the same, the“ realism” of the Wake field Master is of a paradoxical turn. His wide knowledge of people, as well as books indicates no cloistered contemplative but one in close relation to his times. Still, that life was after all a predominantly religious one, a time which never neglected the belief that man was a rebellious and sinful creature in need of redemption, So deeply (onecan hardly say “ naively ” of so sophisticated a writer) and implicitly religious is the Master that he is less able (or less willing) to present actual history realistically than is the author of the Brome“ Abraham and Isaac ” . His historical sense is even less realistic than that of Chaucer who just a fewyears before had done for his own time costume romances, such as The Knight ’ s Tale, Troilus and Cressida, etc. Moreover Chaucer had the excuse of highly romantic materials for taking liberties with history.1. Which of the following statements about the Wake field Master is NOT True?[A].He was Chaucer ’ s contemporary.[B].He is remembered as the author of five or six realistic plays.[C].He write like John Steinbeck.[D].HE was an accomplished artist.2.By “ patristic ” , the author means[A]. realistic. [B]. patriotic[C]. superstitious. [C]. pertaining to the Christian Fathers.3.The statement about the “ secularization of the medieval drama ” refers to the[A]. introduction of mundane matters in religious plays.[B]. presentation of erudite material.[C].use of contemporary introduction of religious themes in the early days.4. In subsequent paragraphs, we may expect the writer of this passage to[A].justify his comparison with Steinbeck.[B].present a point of view which attack the thought of the second paragraph.[C].point out the anachronisms in the play.[D].discuss the works of Chaucer.五The earliest controversies about the relationship between photography and art centered on whether photograph ’ s fidelity to appearances and dependence on a machine allowed it to be a fineart as distinct from merely a practical art. Throughout the nineteenth century, the defence of photography was identical with the struggle to establish it as a fine art. Against the charge that photography was a soulless, mechanical copying of reality, photographers asserted that it was instead a privileged way of seeing, a revolt against commonplace vision, and no less worthy an art than painting.Ironically, now that photography is securely established as a fine art, many photographers find it pretentious or irrelevant to label it as such. Serious photographers variously claim to be finding, recording, impartially observing, witnessing events, exploring themselves—anything but making works of art. They are no longer willing to debate whether photography is or is not a fine art, except to proclaim that their own work is not involved with art. It shows the extent to which they simply takefor granted the concept of art imposed by the triumph of Modernism: the better the art, the more subversive it is of the traditional aims of art.Photographers’ disclaimers of any interest in making art tell us more about the harriedstatus of the contemporary notion of art than about whether photography is or is not art. For example,those photographers who suppose that, by taking pictures, they are getting away from the pretensions ofart as exemplified by painting remind us of those Abstract Expression ist painters who imagined theywere getting away from the intellectual austerity of classical Modernist painting by concentratingon the physical act of painting. Much of photography ’s prestige today derives from the convergence of its aims with those of recent art, particularly with the dismissal of abstract art implicit in thephenomenon of Pop painting during the1960 ’ s. Appreciating photographs is a relief to sensibilities tired of the mental exertions demanded by abstract art. Classical Modernist painting — that is, abstract art as developed indifferent ways by Picasso, Kandinsky, and Matisse — presupposes highly developed skills of looking and a familiarity with other paintings and the history of art. Photography, like Pop painting, reassures viewers that art is not hard; photography seems to be more about its subjects than about art.Photography, however, has developed all the anxieties and self-consciousness of a classic Modernist art. Many professionals privately have begun to worry that the promotion of photography asan activity subversive of the traditional pretensions of art has gone so far that the public will forget that photography is a distinctive and exalted activity — in short, an art.1.What is the author mainly concerned with? The author is concernedwith [A]. defining the Modernist attitude toward art.[B]. explaining how photography emerged as a fine art.[C]. explaining the attitude of serious contemporary photographers toward photography asart and placing those attitudes in their historical context.[D]. defining the various approaches that serious contemporary photographers taketoward their art and assessing the value of each of those approaches.2. Which of the following adjectives best describes “ the concept of art imposed by the triumph of Modernism ” as the author represents it in lines 12 —13?[A]. Objective [B]. Mechanical. [C]. Superficial. [D]. Paradoxical.3. Why does the author introduce Abstract Expressionist painter?[A]. He wants to provide an example of artists who, like serious contemporary photographers, disavowed traditionally accepted aims of modern art.[B]. He wants to set forth an analogy between the Abstract Expressionist paintersand classical Modernist painters.[C].He wants to provide a contrast to Pop artist and others.[D].He wants to provide an explanation of why serious photography, like other contemporary visual forms, is not and should not pretend to be an art.4.How did the nineteenth-century defenders of photography stress the photography?[A]. They stressed photography was a means of making people happy.[B].It was art for recording the world.[C].It was a device for observing the world impartially.[D].It was an art comparable to painting.六The past ages of man have all been carefully labeled by anthropologists. Descriptions like‘ Palaeolithic Man ’, ‘ Neolithic Man ’, etc., neatly sum up whole periods. When the time comes for anthropologists to turn their attention to the twentieth century, they will surely choose the label‘Legless Man ’. Histories of the time will go something like this: ‘ in the twentieth century, people forgot how to use their legs. Men and women moved about in cars, buses and trains from a very early age. There were lifts and escalators in all large buildings to prevent people from walking. This situation was forced upon earth dwellers of that time because of miles each day. But the surprising thing is that they didn ’ t use their legs even when they went on holiday. They built cable railways, ski-lifts and roads to the top of every huge mountain. All the beauty spots on earth were marred by the presence of large car parks. ’The future history books might also record that we were deprived of the use of our eyes. In our hurry to get from one place to another, we failed to see anything on the way. Air travel gives you a bird ’ s-eye view of the world – or even less if the wing of the aircraft happens to get in your way.When you travel by car or train a blurred image of the countryside constantly smears the windows. Car drivers, in particular, are forever obsessed with the urge to go on and on: they never want to stop. Is it the lure of the great motorways, or what? And as for sea travel, it hardly deserves mention. It is perfectly summed up in the words of the old song:‘ I joined the navy to see the world, and what did I see? I saw the sea.’ The typical twentieth-century traveler is the man who always says ‘ I’ ve been there. ’ You mention the remotest, most evocative place-names in the world like El Dorado, Kabul, Irkutsk and someone is bound to say ‘ I ’ve been there’ – meaning, ‘ I drove through it at 100 miles an hour on the way to somewhere else. ’When you travel at high speeds, the present means nothing: you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend all experience; the present ceases to be a reality: you might just as well be dead. The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving are one and the same thing: he arrives somewhere with every step he makes. He experiences the present moment with his eyes, his ears and the whole of his body.

It only goes to show how muchprofit the big companies are making. Why don ’ t they stop advertising and reduce the price of their goods? After all, it ’ s the consumer who pays ⋯’The poor old consumer! He ’ d have to pay a great deal more if advertising didn ’ t create mass markets for products. It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods. Another equally important function is to inform. A great deal of the knowledge we have about household goods derives largely from the advertisements we read. Advertisements introduce us to new products or remind us of the existence of ones we already know about. Supposing you wanted to buy a washing machine, it is more than likely you would obtain details regarding performance, price, etc., from an advertisement.Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would youenjoy gazing at a blank wall or reading railway bye laws while waiting for a train? Would you like toread only closely printed columns of news in your daily paper? A cheerful, witty advertisement makes such a difference to a drab wall or a newspaper full of the daily ration of calamities.We must not forget, either, that advertising makes a positive contribution to our pockets. Newspapers, commercial radio and television companies could not subsist without this source of revenue. The fact that we pay so little for our daily paper, or can enjoy so many broadcast programmes is due entirely to the money spent by advertisers. Just think what a newspaper would cost if wehad to pay its full price!Another thing we mustn ’t forget is the ‘ small ads. ’ which are in virtually every newspaper and magazine. What a tremendously useful service they perform for the community! Just about anythingcan be accomplished through these columns. For instance, you can find a job, buy or sell a house, announce a birth, marriage or death in what used to be called the ‘ hatch, match and dispatch ’ column but by far the most fascinating section is the personal or ‘ agony ’ column. No other item in a newspaper provides such entertaining reading or offers such a deep insight into human nature. It ’ s the best advertisement for advertising there is!1.What is main idea of this passage?A.

Narration.B.Description.C.Criticism.D.Argumentation.八Science is a dominant theme in our culture. Since it touches almost every facet of our life, educated people need at least some acquaintance with its structure and operation. They shouldalso have an understanding of the subculture in which scientists live and the kinds of people theyare. An understanding of general characteristics of science as well as specific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist.This book is written for the intelligent student or lay person whose acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse of dried facts; for the person who sees the chief objective of science as the production of gadgets; and for the person who views the scientists as some sort of magician. The book can be used to supplement a course in any science, to accompany any course that attempts to give an understanding of the modern world, or –independently of any course – simply to provide a better understanding of science. We hope this book will lead readers to a broader perspective on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an awareness and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. In addition, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies that are pervasive in our culture.We have tried to present in this book an accurate and up-to-date picture of the scientific community and the people who populate it. That population has in recent years come to comprise more and more women. This increasing role of women in the scientific subculture is not an unique incident but, rather, part of the trend evident in all segments of society as more women enter traditionally male-dominated fields and make significant contributions. In discussing these changes and contribution, however, we are faced with a language that is implicitly sexist, one that uses male nouns or pronouns in referring to unspecified individuals. To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when absolutely necessary, alternating he and she. This policy is far form being ideal, but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally.We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as do many other scientists, that we shouldn ’ t take ourselves too seriously.As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earn a living.1. According to the passage,‘ scientific subculture’means _____.[A]cultural groups that are formed by scientists.[B]people whose knowledge of science is very limited.[C]the scientific community.[D]people who make good contribution to science.2.We need to know something about the structure and operation of science because_____.[A] it is not easy to understand the things that excite and frustrate scientists.[B] Science affects almost every aspect of our life.[C]Scientists live in a specific subculture.[D]It is easier to understand general characteristics of science.3. The book mentioned in this passage is written for readers who_____.[A]are intelligent college students and lay person who do not know much about science.[B]are good at producing various gadgets.[C]work in a storehouse of dried facts.[D]want to have a superficial understanding of science.4.According to this passage,_____.[A] English is a sexist language.[B] only in the scientific world is the role of women increasing rapidly.[C] women are making significant contributions to eliminating the inadequacy of our language.[D]male nouns or pronouns should not be used to refer to scientists.5. This passage most probably is_____.[A]a book review.[B]the preface of a book.[C]the postscript of a book.[D]the concluding part of a book.九Educators are seriously concerned about the high rate of dropouts among the doctor of philosophy candidates and the consequent loss of talent to a nation in need of Ph. D. s. Some have placed the dropouts loss as high as 50 percent. The extent of the loss was, however, largely a matterof expert guessing. Last week a well-rounded study was published. It was published. It was based on 22,000 questionnaires sent to former graduate students who were enrolled in 24 universities and it seemed to show many past fears to be groundless.The dropouts rate was found to be 31 per cent, and in most cases the dropouts, while not completing the Ph. D. requirement, went on to productive work. They are not only doing well financially, but, according to the report, are not far below the income levels of those who went on to complete their doctorates.Discussing the study last week, Dr. Tucker said the project was initiated ‘ because of the concern frequently expressed by graduate faculties and administrators that some of the individuals who dropped out of Ph. D. programs were capable of competing the requirement for the degree. Attrition at the Ph. D. level is also thought to be a waste of precious faculty time and a drain on university resources already being used to capacity. Some people expressed the opinion that the shortage of。

六级英语冲刺阅读练习附答案解析六级英语冲刺阅读练习原文Every year television stations receive hundreds of complaints about the loudness ofadvertisements. However. federal rules forbid the practice of making ads louder than theprogramming. In addition, television stations always operate at the highest sound levelallowed for reasons of efficiency. According to one NBC executive. no difference exists in thepeak sound level of ads and programming. Given this information. whydo commercials sound soloud?The sensation of sound involves a variety of factors in addition to its peak level. Advertisersare skilful at creating the impression of loudness through their expert use of such factors. Onemajor contributor to the perceived loudness of commercials is that much less variation insound level occurs during a commercial. In regular programming the intensity of sound variesover a large range. However, sound levels in commercials tend to stay at or near peak levels.Other "tricks of the trade" are also used. Because low-frequency sounds can mask higherfrequency sounds. advertisers filter out any noises that may drown out the primary message.In addition, the human voice hasmore auditory (听觉的) impact in che middle frequencyranges. Advertisers electronically vary voice sounds so that they stay within such afrequency band. Another approach is to write the script so that lots ofconsonants(辅音) areused, because people are more aware of consonants than vowel (元音) sounds. Finally,advertisers try to begin commercials with sounds that are highly different from those of theprogramming within which the commercial is buried. Because people become adapted to thetype of sounds coming from programming. a dramatic change in sound quality draws viewerattention. For example. notice how many commercials begin with a cheerful song of some type.The attention-getting property of commercials can be seen by observing one-to-two-year-oldchildren who happen to be playing around a television set. They may totally ignore theprogramming. However. when a commercial comes on.their attention is immediately drawn toit because of its dramatic sound quality.六级英语冲刺阅读练习题目1.

六级长篇阅读冲刺练习及参考答案六级长篇阅读冲刺练习1：How to Make Attractive and Effective PowerPoint PresentationsA Microsoft PowerPoint has dramatically changed the way in which academic and business presentations are made. This article outlines few tips on making more effective and attractive PowerPoint presentations.The TextB Keep the wording clear and simple. Use active, visual language. Cut unnecessary words—a good rule of thumb is to cut paragraphs down to sentences, sentences into phrases, and phrases into key words.Limit the number of words and lines per slide. Try the Rule of Five-five words per line, five lines per slide. If too much text appears on one slide, use the AutoFit feature to split it between two slides. Click within the placeholder to display the AutoFit Options button its symbol is two horizontal lines with arrows above and below, then click on the button and choose Split Text between Two Slides from the submenu.C Font size for titles should be at least 36 to 40, while the text body should not be smaller than 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 usedfor 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 forall 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 ofslides and suggests a more formal situation than having just the first letterof the first word capitalized. In bullet point lines, capitalize the firstword and no other words unless they normally appear capped. Upper and lowercase lettering is more readable than all capital letters. Moreover, current styles indicate that using all capital letters means you are shouting. If you have text that is in the wrong case, select the text, and then click Shift+F3 until it changes to the case style that you like. Clicking Shift+F3 toggles the text case between ALL CAPS, lower case, and Initial Capital styles.G Use bold or italic typeface for emphasis. Avoid underlining, it clutters up the presentation.Don’t center bulleted lists or text. It is confusing to read. Left align unless you have a good reason not to. Run “spell check” on your show when finished.The BackgroundH Keep the background consistent. Simple, light textured backgrounds work well. Complicated textures make the content hard to read. If you are planning to use many clips in your slides, select a white background. If the venue of your presentation is not adequately light-proof, select a dark-colored backgroun d 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 wereoriginally loaded on your computer with the rest of Office. You can easilyfind 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 Saveas type list, click PowerPoint Show. Your slide show file will be saved with a ppt file extension. When you double-click on this file, it will automatically start your presentation in slide show view. When you’re done, PowerPoint automatically closes and you return to the desktop. If you want to edit the slide show file, you can always open it from PowerPoint by clicking Open onthe File menu.L Look at the audience, not at the slides, whenever possible. If using a laser pointer, don’t move it too fast. For example, if circling a num ber onthe 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 turnoff 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 havebeen changed by Microsoft PowerPoint.2.
