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年大学英语六级阅读理解试题及答案(卷一)
2020年大学英语六级阅读理解试题及答案（卷一）A great deal ofattention is being paid today to the so-called digital divide—the divisionof the world into the info(information) rich and the info poor. And that dividedoes exist today. My wife and I lectured about this looming danger twenty yearsago. What was less visible then, however, were the new, positive forces thatwork against the digital divide. There are reasons to be optimistic。
There are technological reasons to hope the digital divide willnarrow. As the Internet becomes more and more commercialized, it is in theinterest of business to universalize access—after all, the morepeople online, the more potential customers there are. More and moregovernments, afraid their countries will be left behind, want to spreadInternet access. Within the next decade or two, one to two billion people onthe planet will be netted together. As a result, I now believe the digitaldivide will narrow rather than widen in the years ahead. And that is very goodnews because the Internet may well be the most powerful tool for combatingworld poverty that we've ever had。
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。
2020年6月英语六级阅读真题及答案(1)
2020年6月英语六级阅读真题及答案2020年6月英语六级阅读真题及答案Section ADirections： In this section, there is a short passagewith 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer Sheet 2.Questions 47 to 51 are based on the following passage.How good are you at saying "no"? For many, it'ssurprisingly difficult. This is especially true of editors, who by nature tend to be eager and engaged participants in everything they do. Consider these scenarios：It's late in the day. That front-page package you've been working on is nearly complete; one last edit and it's finished. Enter the executive editor, who makes a suggestion requiring a more-than-modest rearrangement of the design and the addition of an information box. You want to scream： "No! It's done!" What do you do?The first rule of saying no to the boss is don't say no. She probably has something in mind when she makes suggestions, and it's up to you to find out what. The second rule is don't raise the stakes by challenging her authority. That issue is already decided. The third rule is to be ready to citeoptions and consequences. The boss's suggestions might be appropriate, but there are always consequences. She might not know about the pages backing up that need attention, or aboutthe designer who had to go home sick. Tell her she can have what she wants, but explain the consequences. Understand what she's trying to accomplish and propose a Plan B that will make it happen without destroying what you've done so far.Here's another case. Your least-favorite reporter suggests a dumb story idea. This one should be easy, but it's not. If you say no, even politely, you risk inhibitingfurther ideas, not just from that reporter, but from others who heard that you turned down the idea. This scenario is common in newsrooms that lack a systematic way to filter story suggestions.Two steps are necessary. First, you need a system for how stories are proposed and reviewed. Reporters can tolerate rejection of their ideas if they believe they were given a fair hearing. Your gut reaction (本能反应) and dismissive rejection, even of a worthless idea, might not qualify as systematic or fair.Second, the people you work with need to negotiate a "What if ...?" agreement covering "What if my idea is turned down?" How are people expected to react? Is there an appeal process? Can they refine the idea and resubmit it? By anticipating "What if...?" situations before they happen, you can reach understanding that will help ease you out of confrontations.47. Instead of directly saying no to your boss, you should find out __________.48. The author's second warning is that we should avoid running a greater risk by __________.49. One way of responding to your boss's suggestion is to explain the __________ to her and offer an alternative solution.50. To ensure fairness to reporters, it is important toset up a system for stories to __________.51. People who learn to anticipate "What if...?"situations will be able to reach understanding and avoid__________.参考答案47. what is in your boss's mind48. challenging our boss's anthority49. possible consequences50. be proposed and reviewed51. feeling uneasy about the confrontationsSection 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 Sheet 2 with a single line through the centre.Passage OneQuestions 52 to 56 are based on the following passage.At the heart of the debate over illegal immigration lies one key question： are immigrants good or bad for the economy? The American public overwhelmingly thinks they're bad. Yetthe consensus among most economists is that immigration, both legal and illegal, provides a small net boost to the economy. Immigrants provide cheap labor, lower the prices ofeverything from farm produce to new homes, and leave consumers with a little more money in their pockets. So whyis there such a discrepancy between the perception of immigrants' impact on the economy and the reality?There are a number of familiar theories. Some argue that people are anxious and feel threatened by an inflow of new workers. Others highlight the strain that undocumented immigrants place on public services, like schools, hospitals, and jails. Still others emphasize the role of race, arguing that foreigners add to the nation's fears and insecurities. There's some truth to all these explanations, but they aren't quite sufficient.To get a better understanding of what's going on,consider the way immigration's impact is felt. Though its overall effect may be positive, its costs and benefits are distributed unevenly. David Card, an economist at UC Berkeley, notes that the ones who profit most directly from immigrants' low-cost labor are businesses and employers – meatpacking plants in Nebraska, for instance, or agricultural businessesin California. Granted, these producers' savings probably translate into lower prices at the grocery store, but howmany consumers make that mental connection at the checkout counter? As for the drawbacks of illegal immigration, these, too, are concentrated. Native low-skilled workers suffer mostfrom the competition of foreign labor. According to a study by George Borjas, a Harvard economist, immigration reduced the wages of American high-school dropouts by 9% between 1980-2000.Among high-skilled, better-educated employees, however, opposition was strongest in states with both high numbers of immigrants and relatively generous social services. What worried them most, in other words, was the fiscal (财政的)burden of immigration. That conclusion was reinforced by another finding： that their opposition appeared to soften when that fiscal burden decreased, as occurred with welfare reform in the 1990s, which curbed immigrants' access to certain benefits.The irony is that for all the overexcited debate, the net effect of immigration is minimal. Even for those most acutely affected – say, low-skilled workers, or California residents – the impact isn't all that dramatic. "The unpleasant voices have tended to dominate our perceptions," says Daniel Tichenor, a political science professor at the University of Oregon. "But when all those factors are put together and the economists calculate the numbers, it ends up being a net positive, but a small one." Too bad most people don't realize it.注意：此部分试题请在答题卡2上作答。

It is amost useful instinct, for the developing child mustlearn andmaster a vast repertoire1 of behavior inshort order.But while children have instinctive desire to imitate, they do not possessan instinct fordetermining whether a behavior ought to be imitated. They willimitate anything, includingbehavior that most adults regard as destructive andantisocial2. It may give pause forthought, then, to learn that infants as youngas fourteen months demonstrably observe andincorporate behavior seen ontelevision.The average American preschooler watches more than twenty-seven hours oftelevision perweek.

2020年大学英语六级阅读理解预测题及答案5
2020年大学英语六级阅读理解预测题及答案5The destruction of our natural resources and contamination of our food supply continue occur, largely because of the extreme difficulty in affixing (把…固定)legal responsibility on those who continue to treat our environment with reckless abandon (放任). Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been net by lawsuits, personal and industrial denial and long delays—not only in accepting responsibility, but more importantly, in doing something about it.It seems that only when government decides it can afford tax incentives or production sacrifices is there anyinitiative for change. Where is industry’s and our recognition that protecting mankind’s great treasure is the single most important responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now.We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change. However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge.We must recognize that environmental health issues do not stop at city limits, county lines, state or even federalboundaries. We can no longer afford to be tunnel-visioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion.I believe we have a three-part mission for the present. First, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can accomplish these three goals in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages.16. We can infer from the first two paragraphs that the industrialists disregard environmental protection chiefly because ________.A) they are unaware of the consequences of what they are doingB) they are reluctant to sacrifice their own economic interestsC) time has not yet come for them to put due emphasis on itD) it is difficult for them to take effective measures17. The main task now facing ecologists, environmental activists and conservationists is ________.A) to prevent pollution by legislation, economic incentives and persuasionB) to arouse public awareness of the importance of environmental protectionC) to take radical measures to control environmental pollutionD) to improve the quality of life by enforcing environmental standards18. The word “tunnel-visioned (Line 2, Para. 4) most probably means “________”.A) narrow-mindedB) blind to the factsC) short-sightedD) able to see only one aspect19. Which of the following, according to the author, should play the leading role in the solution of environmental problems?A) Legislation and government intervention.B) The industry’s understanding and support.C) The efforts of environmental health professionals.D) The cooperation of ecologists, environmental activists and conservationists.20. Which of the following is true according to the last paragraph?A) Efforts should be exerted on pollution prevention instead of on remedial measures.B) More money should be spent in order to stop pollution.C) Ordinary citizens have no access to technical information on pollution.D) Environmental degradation will be stopped by the end of this decade.参考答案：BBDCC。

2020 年英语六级阅读理解预测题及答案10Which is safer-staying at home，traveling to work onpublic transport，or working in the office? Surprisingly，each of these carries the same risk，which is very low.However， what about flying compared to working in thechemical industry? Unfortunately，the former is 65 timesriskier than the latter! In fact，the accident rate ofworkers in the chemical industry is less than that of almostany of human activity，and almost as safe as staying at home.The trouble with the chemical industry is that when thingsgo wrong they often cause death to those living nearby. It is thiswhich makes chemical accidents so newsworthy. Fortunately ，they are extremely rare. The most famous oneshappened at Texas City (1947)，Flixborough (1974)，Seveso (1976) ， Pemex (1984) and Bhopal (1984)。
Some of these are always in the minds of the people eventhough the loss of life was small. No one died at Seveso ， and only28 workers at Flixborough. The worst accident of allwas Bhopal ， where up to 3 ，000 were killed. The Texas Cityexplosion of fertilizer killed 552. The Pemex fire at astorage plant for natural gas in the suburbs of Mexico Citytook 542 lives ， just a month before the unfortunate event atBhopal.Some experts have discussed these accidents and usedeach accident to illustrate a particular danger. Thus the TexasCity explosion was caused by tons of ammonium nitrate( 硝酸铵) ，which is safe unless stored in great quantity. TheFlixborough fireball was the fault of management ，which tookrisks to keep production going during essential repairs. TheSeveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep. When the poisonousgas drifted over the town ， local leaders were incapable oftaking effective action. The Pemex fire was made worse by anoverloaded site in an overcrowded suburb. The fire set off a chain，reaction os exploding storage tanks. Yet by a miracle ， the twolargest tanks did not explode. Had these caught fire ， then 3 ，000 strong rescue team and firefighters would all have died.1.Which of the following statements is true?A.Working at the office is safer than staying at home.B.Traverlling to work on public transport is saferthan working at the office.C.Staying at home is safer than working in thechemical industry.D.Working in the chemical industry is saferthan traveling by air.2.Chemical accidents are usually important enough to bereported as news because ____.A.they are very rareB.they often cause loss of lifeC.they always occur in big citiesD.they arouse the interest of all the readers3.According to passage ， the chemical accident that caused by the fault of management happened at ____.A.Texas cityB.FlixboroughC.SevesoD.Mexico City4.From the passage we know that ammonium nitrate is a kind of ____.A.natural gas，which can easily catch fireB.fertilizer， which can't be stored in a great quantityC.poisonous substance ， which can't be used in overcrowded areasD.fuel ， which is stored in large tanks5.From the discussion among some experts we may coclude that ____.A.to avoid any accidents we should not repair thefacilities in chemical industryB.the local authorities should not be concerned with the production of the chemical industryC.all these accidents could have been avoided or controlled if effective measure had been takenD.natural gas stored in very large tanks is always safe答案： DBABC。

2020年大学英语六级阅读理解试题及答案(卷五)
2020年大学英语六级阅读理解试题及答案（卷五）Certainly no creature in the sea is odder than the common sea cucumber. All living creature，especially human beings，have their peculiarities，but everything about the little sea cucumber seems unusual. What else can be said about a bizarre animal that，among other eccentricities，eats mud，feeds almost continuously day and night but can live without eating for long periods，and can be poisonous but is considered supremely edible by gourmets?For some fifty million years，despite all its eccentricities，the sea cucumber has subsisted on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet，under rocks in shallow water，or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores，it has the ability to suck up mud or sand and digest whatever nutrients are present.Sea cucumbers come in a variety of colors，ranging from black to reddish brown to sand color and nearly white. One form even has vivid purple tentacles. Usually the creatures are cucumber shaped-hence their name-and because they are typically rock inhabitants，this shape，combined with flexibility，enables them to squeeze into crevices where they are safe from predators and ocean currents.Although they have voracious appetites，eating day and night，sea cucumbers have the capacity to become quiescent and live at a lowmetabolic rate-feeding sparingly or not at all for long periods，so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty，they would devour all the food available in a short time and would probably starve themselves out of existence.But the most spectacular thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs，when attacked，it squirts all its internal organs into water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself if it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.?1. According to the passage，why is the shape of sea cucumbers important??A. It helps them to digest their food.?B. It helps them to protect themselves from danger.?C. It makes it easier for them to move through the mud.?D. It makes them attractive to fish. ?2. The fourth paragraph of the passage primarily discusses______.?A. the reproduction of sea cucumbers?B. the food sources of sea cucumbers?C. the eating habits of sea cucumbers?D. threats to sea cucumbers' existence ?3. What can be inferred about the defence mechanisms of the sea cucumber??A. They are very sensitive to surrounding stimuli.?B. They are almost useless.?C. They require group cooperation.?D. They are similar to those of most sea creatures. ?4. Which of the following would NOT cause a sea cucumber to release its internal organs into the water??A. A touchB. Food?C. Unusually warm waterD. Pollution.【答案】1. B) 通过阅读文章可以排除选项A、C、D，因为文中没有提及，故选项B为正确答案。
2020年英语六级阅读理解预测题及答案（2）
2020年英语六级阅读理解预测题及答案（2）2020年英语六级阅读理解预测题及答案(2)In the last two hundred years there have been great changes in the method of production of goods. This is nowalso true of the building industry; for mechanization hasbeen introduced. System building can save both time and money. The principle of system building is that the building is made from a set of standard units. These are either made at the building-site or at a factory. Some designers, in fact, are standardizing the dimensions of rooms. They are made in multiples of a single fixed length, usually ten centimeters. This is called a modular (标准件的) system, and it means that manufactures can produce standardized fittings at a lower cost. The most important fact about system building is its speed. A ten-storey flat, for example, can be completed infour months.There are several new methods of system building. One is the panel method. In this case, the construction company sometimes erects a factory on the site. The walls and floorsof the building, called panels, are cast in a horizontal or vertical position. Conduits for electrical wires and sleeves for pipes are cast in the panels when they are being made.The moulds for making these castings are situated all around the building.After the concrete panels are cast, they are allowed toset and harden for a week. Next they are lifted by a tower crane on to any section of the building. There the panels are cemented together at their joints and the floor covering is laid.After the panels have been cemented together, the crane liftsa case into the area. It contains all the fittings to be installed, such as wash-basins, radiators and pipes. Finishing tradesmen, such as plumbers, plasterers, painters and electricians, follow behind to complete the work.In some building developments, in some countries, whole flats with internal features like their bathrooms, bedrooms and connecting stairs, and weighing as much as twenty tons, are carried to the building-site ready-made. A giant overhead crane is used to lift them into position. In the future, this method may become more widespread.1. The main difference between panel method and the method discussed in the last paragraph is_______.A. the latter uses ready-made internal featuresB. panels are cast in a level positionC. the former is used to build walls and floors while the latter to construct bathrooms or bedroomsD. the former is more expensive than the latter2. Which of these statements is TRUE of system building?A. It employs more men.B. It is difficult and dangerous.C. It can save both time and money.D. It means less mechanization.3. According to the passage, the principle of system building is that_______.A. construction methods are saferB. buildings are made from a set of standardized unitsC. similar buildings can be producedD. all units are produced on the site4. The usual fixed length in the modular system is_______.A. twenty centimetersB. ten millimetersC. fifty centimetersD. ten centimeters5. What lifts the concrete panels onto the building?A. Cranes.B. Man-power.C. Pulleys.D. Hydraulic jacks.参考答案： 1. A 2. C 3. B 4. D 5. A。
2020年英语六级阅读理解预测题及答案(4)
2020年英语六级阅读理解预测题及答案(4)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’ suspici ons 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 1975 psychologist Robert Ader at the University of RochesterSchool 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 reasonfor 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年英语六级阅读理解预测题及答案(6)
2020年英语六级阅读理解预测题及答案(6)阅读文章：I live in the land of Disney， Hollywood and year-round sun. You may think people in such a glamorous， fun-filled place are happier than others. If so， you have some mistaken ideas about the nature of happiness.Many intelligent people still equate happiness with fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper， moreabiding emotion.Going to an amusement park or ball game， watching amovie or television， are fun activities that help us relax，temporarily forget our problems and maybe even laugh. Butthey do not bring happiness， because their positive effects end when the fun ends.I have often thought that if Hollywood stars have a roleto play， it is to teach us that happiness has nothing to do with fun. These rich， beautiful individuals have constant access to glamorous parties， fancy cars， expensive homes，everything that spells “happiness”。

2020年6月英语六级阅读理解模拟题及答案
2020年6月英语六级阅读理解模拟题及答案
Which is safer-staying at home， traveling to work on public transport， or working in the office? Surprisingly，each of these carries the same risk， which is very low. However， what about flying compared to working in the chemical industry? Unfortunately， the former is 65 times riskier than the latter! In fact， the accident rate of workers in the chemical industry is less than that of almost any of human activity， and almost as safe as staying at home.
The trouble with the chemical industry is that when
things go wrong they often cause death to those living nearby. It is this which makes chemical accidents so newsworthy. Fortunately， they are extremely rare. The most famous ones happened at Texas City (1947)，Flixborough (1974)， Seveso (1976)， Pemex (1984) and Bhopal (1984)。
Some of these are always in the minds of the people even though the loss of life was small. No one died at Seveso，
and only 28 workers at Flixborough. The worst accident of all was Bhopal， where up to 3，000 were killed. The Texas City explosion of fertilizer killed 552. The Pemex fire at a
storage plant for natural gas in the suburbs of Mexico City took 542 lives， just a month before the unfortunate event at Bhopal.
Some experts have discussed these accidents and used each accident to illustrate a particular danger. Thus the Texas
City explosion was caused by tons of ammonium nitrate(硝酸铵)，which is safe unless stored in great quantity. The
Flixborough fireball was the fault of management， which took risks to keep production going during essential repairs. The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep. When the poisonous gas drifted over the town， local leaders were incapable of taking effective action. The Pemex fire was made worse by an overloaded site in an overcrowded suburb. The
fire set off a chain reaction os exploding storage tanks. Yet，by a miracle， the two largest tanks did not explode. Had
these caught fire， then 3，000 strong rescue team and fire fighters would all have died.
1.Which of the following statements is true?
A.Working at the office is safer than staying at home.
B.Traverlling to work on public transport is safer than working at the office.
C.Staying at home is safer than working in the chemical industry.
D.Working in the chemical industry is safer than
traveling by air.
2.Chemical accidents are usually important enough to be reported as news because ____.
A.they are very rare
B.they often cause loss of life
C.they always occur in big cities
D.they arouse the interest of all the readers
3.According to passage， the chemical accident that caused by the fault of management happened at ____.
A.Texas city
B.Flixborough
C.Seveso
D.Mexico City
4.From the passage we know that ammonium nitrate is a kind of ____.
A.natural gas， which can easily catch fire
B.fertilizer， which can't be stored in a great quantity
C.poisonous substance， which can't be used in overcrowded areas
D.fuel， which is stored in large tanks
5.From the discussion among some experts we may coclude that ____.
A.to avoid any accidents we should not repair the facilities in chemical industry
B.the local authorities should not be concerned with the production of the chemical industry
C.all these accidents could have been avoided or controlled if effective measure had been taken
D.natural gas stored in very large tanks is always safe
