大学英语六级（阅读）模拟试卷5(题后含答案及解析)题型有：1. Perhaps the most challenging consideration for the future is security. Smartphones and PDAs are already popular among many corporate executives, who often use their phones to transmit confidential information. Smartphones may be vulnerable to security breaches such as an Evil Twin attack. In an evil twin attack, a hacker sets a server’s service identifier(标识符)to that of a legitimate hotspot or network while simultaneously blocking traffic to the real server. When a user connects with the hacker’s server, information can be tapped and security is compromised. One downside to the openness and configurability(可配置性)of smartphones is that it also makes them susceptible to viruses. Hackers have written viruses that attack SymbianOS(操作系统)phones. The viruses can do things like turning off anti-virus software, locking the phone completely or deleting all applications stored on the phone. On the other side, some critics argue that anti-virus software manufacturers greatly exaggerate the risks, harms and scope of phone viruses in order to help sell their software. The incredible diversity in smartphone hardware, software and network protocols restrain practical, broad security measures. Most security considerations either focus on particular operating systems or have more to do with user behavior than network security. With data transmission rates reaching fast speeds and the incorporation of WiFi(无线局域网)technology, the sky is the limit on what smartphones can do. Possibly the most exciting thing about smartphone technology is mat the field is still wide open. It’s an idea that probably hasn’t found its perfect, real-world implementation yet. Every crop of phones brings new designs and new interface ideas. No one developer or manufacturer has come up with the perfect shape or size yet. The next generation smartphone could look like a flip phone, a tablet PC, a candy bar or something no one has conceived of yet.1．Nokia 6131i is in the trial phase of development in the function of acting as a______.A．call receiverB．PIMC．wireless credit cardD．PDA正确答案：C解析：文中说诺基亚613li有无线信用卡的功能，但尚在实验阶段，选[C]。
英语六级阅读理解模拟练习附答案
英语六级阅读理解模拟练习附答案六级阅读理解模拟练习一：Which is safer-staying at home， traveling towork on public transport，or working in the office?Surprisingly， each of these carries the same risk，which is very low. However， what about flyingcompared to working in the chemical industry?Unfortunately， the former is 65 times riskier thanthe latter! In fact， the accident rate of workers inthe chemical industry is less than that of almost anyof 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 deathto 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 wasBhopal， where up to 3，000 were killed. The Texas City explosion of fertilizer killed 552. ThePemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives， justa month before the unfortunate event at Bhopal.Some experts have discussed these accidents and used each accident to illustrate aparticular 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 ofmanagement， which tookrisks to keep production going during essential repairs. The Sevesoaccident shows what happens if the local authorities lack knowledge of the danger on theirdoorstep. When the poisonous gas drifted over the town， local leaders were incapable oftaking effective action. The Pemex fire was made worse by an overloaded site in anovercrowded suburb. The fire set off a chain reaction os exploding storage tanks. Yet， by amiracle， the two largest tanks did not explode. Had these caught fire，then 3，000 strongrescue 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 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 managementhappened 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 cant be stored in a great quantityC.poisonous substance， which cant 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 the facilities in chemical industryB.the local authorities should not be concerned with the production of the chemicalindustryC.all these accidents could have been avoided or controlled if effective measure hadbeen takenD.natural gas stored in very large tanks is always safe参考答案：DBABC六级阅读理解模拟练习二：40 years ago the idea of disabled people doingsport was never heard of. But when the annualgames for the disabled were started atStokeMandeville, England in 1948 by Sir LudwigGuttmann, the situation began to change.Sir Ludwig Guttmann, who had been driven toEngland in 1939 from Nazi Germany, had been askedby the British government to set up an injuriescenter at Stoke Mandeville Hospital near London. His ideas about treating injuries includedsport for the disabled.In the first games just two teams of injured soldiers took part. The next year, 1949, fiveteams took part. From those beginnings, things have developed fast. Teams now come fromabroad to Stoke Mandeville every year. In 1960 the first Olympics for the Disabled were held inRome, in the same place as the normal Olympic Games. Now, every four years the OlympicGames for the Disabled are held, if possible, in the same place as the normal Olympic Games,although they are organized separately. In other years Games for the Disabled are still held atStoke Mandeville. In the 1984 wheelchair Olympic Games, 1064 wheelchair athletes from about40 countries took part. Unfortunately, they were held at Stoke Mandeville and not in LosAngeles, along with the other Olympics.The Games have been a great success in promoting international friendship andunderstanding, and in proving that being disabled does not mean you cant enjoy sport. Onesmall source of disappointment for those who organize and take part in the games,however, has been the unwillingness of the International Olympic Committee to includedisabled events at Olympic Games for the able-bodied. Perhaps a few more years are stillneeded to convince those fortunate enough not to be disabled that their disabled fellowathletes should not be excluded.21. The first games for the disabled were held______after Sir Ludwig Guttmann arrived inEngland.A. 40 yearsB. 21 yearsC. 10 yearsD. 9 years22. Besides Stoke Mandeville, surely the games for the disabled were once held in______.A. New YorkB. LondonC. RomeD. Los Angeles23. In Paragraph 3, the word "athletes" means______.A. people who support the gamesB. people who watch the gamesC. people who organize the gamesD. people who compete in the games24. Which of the following statements is NOT true?A. Sir Ludwig Guttmann is an early organizer of the games for the disabled.B. Sir Ludwig Guttmann is an injured soldier.C. Sir Ludwig Guttmann is from Germany.D. Sir Ludwig Guttmann is welcomed by the British government.25. From the passage, we may conclude that the writer is ______.A. one of the organizers of the game for the disabledB. a disabled person who once took part in the gamesC. against holding the games for the disabledD. in favor of holding the games for the disabled 参考答案：21.

But without fire,life on earth was very difficult.Food had to be eaten raw;houses could not be kept warm.Tools had to be of stone,because there was no fire for working metal.Athena,daughter of Zeus,had been watching over Prometheus and had helped him in his work.Now,because Prometheus was kind and wanted man to be comfortable on earth,he called upon Athena to help him get fire from Mount Olympus.She knew that Zeus was away and promised to lead Prometheus to Mount Olympus by a secret path...Just as he arrived Apollo came back from his day’s journey in his chariot of the sun.Prometheus lit a torch from the chariot and put the fire in a hollow stalk that he concealed under his cloak.Then he stole away without being seen by any of the gods,and brought his fire to earth.When Prometheus lit the first campfire on earth,the people were afraid of it.But they trusted him,and so they came closer and closer and enjoyed the fire’s pleasant warmth and beautiful glow.Prometheus knew that he would not have much time before Zeus discovered that he had been disobedient.But he also knew that,powerful as Zeus was,once a god had given a gift it could not be taken away.So he quickly taught the mortals how to use the gift of fire.Ⅰ.Fill in each blank with word or phrase in the p as sage:1.Zeus told Prometheus to teach the_______（人类）anything they needed to know in order to live.2.Prometheus was so happy to_______（帮助）to man that he taught people how to make their own tools and how to build homes for themselves.3.Athena,daughter of Zeus,had been_______（监督）Prometheus and had helped him in his work.4.Prometheus knew that he would not have much time before Zeus discovered that he had been_____（违命）.Ⅱ.Question:When the first campfire was lit on earth,how did human react to it?参考答案Ⅰ. 1.mortals2.be of service3.watching over4.disobedientⅡ.When the first campfire was lit on earth,the people were afraid of it.As they trusted Prometheus,they came closer and closer and enjoyed the fire’s pleasant warmth and beautiful glow.。
英语六级阅读模拟练习题和答案
英语六级阅读模拟练习题和答案Eat more, Play more—Weigh LessIn the United States, 20 to 40 percent of the adult population has a "weight problem. " To many people, the cause seems obvious; we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they consumed more food. In those days people worked harder physically, walked more, used machines much less, didnt watch television.Several modern studies, moreover ? have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3454 London office workers, reveal that, on balance, fat people eat less than slimmer people.Studies show that slim people are more active than fat people. Measurement of calorie intake in slim, active populations compared with moderately overweight, inactive groups routinely shows striking differences. A study by my research group at Stanford University School of Medicine found that among slim, tennis-playing women (ages 32 to 45;11 hours per week) average daily calorie intake was 2417, while among sedentary (坐着的), moderately overweight women of the same age it was 1490. Here were slim women remaining slim on 62 percent more calories than overweight women. The critical difference; physical activity.In another Stanford study, 48 sedentary men ages 30 to 55 started on a one-year jogging program. We observed these changes after the training period:The more the men ran, the greater their loss of body fat.The more they ran, the greater their increase in food intake.Thus, those who ran the most ate the most, yet lost the greatest amount of body fat!I believe that this illustrates the evolution of moderately overweight people to relatively slim individuals via a progressive program of regular exercise. The crucial ingredient is regular, enjoyable activity.Use of energy (calories) by the body falls into two categories. The first is energy used for essential bodily functions—digestion, heart beat, breathing—and is known as the basal metabolic rate, or BMR. In an average-sized adult, BMR requires about 1400 calories per day.The second category is energy used for physical activity—standing, walking and all other movements. Together with the BMR, it makes up total calorie use, which should be balanced by food intake for weight to remain stable.An inactive person might add only 300 calories a day to his BMR, for an average total of 1700. But a marathon runner might add 2300, for a total of 3700. For endurance athletes in training, 4000- to 5000-calorie intakes are not uncommon.We can see from such figures that the sedentary person has aBMR-dominated total calorie expenditure, so that anything he does to increase his BMR will help burn fat, whereas anything he does to decrease his BMR will compound his overweight problem.For years now, we have known that dieting—especially severe dieting(400 calories per day, for instance)—decreases BMR. This is the bodys defense mechanism to conserve energy when food supply is reduced. Unfortunately, it tends to undermine the diets effects by enabling the body to "get by" on fewer calories. For this reason, I believe that severe dieting should be used sparingly, and all dieting should be seen as a temporary measure.A fascinating concept that has emerged in recent years has been the apparent effect of vigorous exercise in temporarily increasing BMR. A jogger returning from a five-mile run may have a higher BMR. While this effect probably lasts only a few hours, the jogger who runs every day should maintain an increased BMR.We can see, then, that the sedentary, overweight person who diets severely without exercise decreases his BMR; does not increase calorie expenditure; has an initially rapid rate of weight loss that soon becomes disappointingly slow; and does not enjoy the experience.On the other hand, the sedentary, overweight person who diets moderately and adopts a slowly progressive exercise program tends to increase his BMR; increases calorie expenditure; has a moderate rate of weight loss that does not slow down after a few weeks; and often enjoys the experience.In addition to facilitating weight loss and continued weight control, regular exercise has many other features to recommend it. While weight loss by dieting alone results in some loss of muscle as well as fat, weight loss by exercise and moderate dieting leads to an increased proportion of muscle mass. The regular exerciser has good heart function too. He is physically fit and can perform betterthan the unfit dieter when it comes to hiking, furniture moving, even making love.Regular exercise helps to raise blood levels of high-density lipoprotein (HDL), the "good" cholesterol (胆固醇) that may work to prevent coronary heart disease, while it reduces levels of low-density lipoprotein (LDL) , the "bad" cholesterol. Since the results of a ten-year study on 3806 middle-aged men were announced in January 1984 by the National Heart, Lung, and Blood Institute, we can say that lowering LDL levels will definitely reduce the number of heart attacks and save lives.Exercise also slow mineral loss from bones, and improves ones mental outlook. A study of 17,000 Harvard alumni (男校友) from 1962 to 1978 provided the first substantial evidence that physical activity maintained through adulthood leads to longer life.The benefits of eating more because of an increase in physical activity are not widely appreciated. Many people in this country, by actual measurement, have remarkably low calorie intake. Often the amount is so low (1200 to 1800 calories a day) that nutritionists worry about the adequacy of their vitamin and mineral intake. And too little food, with inadequate fiber content, leads in the older sedentary population to chronic constipation(长期便秘).Increased exercise leads to increased food intake and thus to increased intake of critical nutrients. So robust eating is no sin. It is the way we were designed to function, the complement to an active life-style.There are some interesting social consequences of a move toward more exercise, with robust eating. Most people like eating and can learn (as most runners have) that uninhibited social eating is more enjoyable than a sedentary life accompanied by cautious nibbling.To sum up: Most Americans still get too little regular exercise, and it is within this group that almost all obesity (肥胖) is found. Severe dieting is not a good way to lose weight. It is unpleasant and tends to be self-defeating. Moderate dieting combined with regular exercise is much more effective and enjoyable. Eventually, the overweight person becomes transformed into a slim person—more active, fitter, with a reduced risk of chronic disease and earlier death, and often able to eat substantially more than when fat.The choice is yours: life on the sofa, nibbling celery-or the active, robust-eating, healthful way.1. According to several studies, overweight people, many of whom think they eat too 198much, generally eat less than thinner people.2. If you want to keep your weight stable, you should get a balance between food intake and BMR.3. The sensible path to slimness and good health is an enjoyable combination of regular exercise and robust eating.4. Mere dieting will never have a good effect because there is no increase of calorie expenditure.5. A person who regularly jogs eats a lot, burns many calories, and loses much weight.6. It should be accepted that eating more will not make people overweight but will provide them with more nutrients.7. Weight loss by exercise should proceed slowly and gradually witha short rest at regular intervals.8. BMR stands for______.9. Exercise helps to raise blood levels of high-density lipoprotein, which may______.10. In America, about a third of the adult population has a______.I. Y 2. N 3. Y 4. Y 5. N 6. N 7.

大学英语六级阅读理解模拟题及答案
大学英语六级阅读理解模拟题及答案英语六级阅读理解模拟题一：If the old maxim that the customer is always right still has meaning, then the airlines that ply the world’s busiest air route between London and Paris have a flight on their hands.The Eurostar train service linking the UK and French capitals via the Channel Tunnel is winning customers in increasing numbers. In late May, it carried its one millionth passenger, havingrun only a limited service between London, Paris and Brussels since November 1994, starting with two trains a day in each direction to Paris and Brussels. By 1997, the company believes that itwill be carrying ten million passengers a year, and continue to grow from there.From July, Eurostar steps its service to nine trains each way between London and Paris, and five between London and Brussels. Each train carries almost 800 passengers, 210 of them in firstclass.The airlines estimate that they will initially lose around 15%-20% oftheir London-Paris traffic to the railways once Eurostar starts a full service later this year 1995, with 15 trains aday each way. A similar service will start to Brussels. The damage will be limited, however, the airlines believe, with passenger numbers returning to previous levels within two to three years.In the short term, the damage caused by the 1 million people-levels traveling between London and Paris and Brussels on Eurostar trains means that some air services are already suffering. Someof the major carriers say that their passenger numbers are down by less than 5% and point to their rivals-Particularly Air France-as having suffered the problems. On the Brussels route, therailway company had less success, and the airlines report anything from around a 5% drop to no visible decline in traffic.The airlines’ optimism on returning traffic levels is based on historical precedent. British Midland, for example, points to its experience on Heathrow Leeds Bradford service which sawpassenger numbers fold by 15% when British Rail electrified and modernized the railway line between London and Yorkshire. Two years later, travel had risen between the two destinations to thepoint where the airline was carrying record numbers of passengers.1.British airlines confide in the fact that__.A.they are more powerful than other European airlines.B.their total loss won’t go beyond a drop of 5% passengers.C.their traffic levels will return in 2-3 years.D.traveling by rail can never catch up with traveling by air.2.The author’s attitude towards the drop of passengers may be described as__.A.worried.B.delightedC.puzzled.D.unrivaled.3.In the passage, British Rail Para 6 is mentioned to__.A.provide a comparison with Eurostar.B.support the airlines’ optimism.C.prove the inevitable drop of air passengers.D.call for electrification and modernization of the railway.4.The railway’s Brussels route is brought forth to show that__.A.the Eurostar train service is not doing good business.B.the airlines can well compete with the railway.C.the Eurostar train service only caused little damage.D.only some airlines, such as Air France, are suffering.5.The passage is taken from the first of an essay, from which we may well predict that in the following part the author is going to__.A.praise the airlines’ clear-mindedness.B.warn the airlines of high-speed rail services.C.propose a reduction of London/Paris flights.D.advise the airlines to follow British Midland as their model.答案：CABCB英语六级阅读理解模拟题二：Without regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify moods and actions, ourinclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help todetermine the development of bodily form and may even determine an individual’s behavioral capacities. Later in life the changing outputs of some endocrine glands and the body’s changingsensitivity to some hormones are essential aspects of the phenomena of aging.Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergenceof endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substanceis secreted from cells in the intestinalwalls when food enters the stomach; it travels through the bloodstream and stimulates the pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secretchemical agents that are conveyed by the bloodstream and regulatedistant target organs or tissues. Bayliss and starling demonstrated that chemical integration could occur without participationof the nervous system.The term “hormone” was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning “to excite or set in motion. T he term “endocrine” was introducedshortly thereafter “Endocrine” is used to refer to glands that secret products into the bloodstream. The term “endocrine” contrasts with “exocrine”, which is applied to glands that secret theirproducts though ducts to the site of action. Examples of exocrine glandsare the tear glands, the sweat glands, and the pancreas, which secrets pancreatic juice through a duct into theintestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless.1.What is the author’s main purpose in the passage?A.To explain the specific functions of various hormones.B.To provide general information about hormones.C.To explain how the term “hormone” evolved.D.To report on experiments in endocrinology.2.The passage supports which of the following conclusions?A.The human body requires large amounts of most hormones.B.Synthetic hormones can replace a person’s natural supply of hormones if necessary.C.The quantity of hormones produced and their effects on the body are related to a person’s age.D.The short child of tall parents very likely had a hormone deficiency early in life.3.It can be inferred from the passage that before the Bayliss and Starling experiments, most people believed that chemical integration occurred only___.A.during sleep.B.in the endocrine glands.C.under control of the nervous system.D.during strenuous exercise.4.The word “liberate” could best be replaced by which of the following?A.EmancipateB.DischargeC.SurrenderD.Save5.According to the passage another term for exocrine glands is___.A.duct glandsB.endocrine glandsC.ductless glandsD.intestinal glands.答案：BDCBA感谢您的阅读，祝您生活愉快。

Until that time, UnitedStates territory had extended from the Atlantic Ocean to the banks of the Mississippi and from theGreat Lakes and the St. Lawrence River to the thirty-first parallel. The national land now wasexpanded westward to include practically all of the area between the Mississippi River and the RockyMountains and between the Gulf of Mexico and the Canadian border. On that day, for fifteen milliondollars, the United States purchased from France 875,000 square miles of territory. After Robert R.Livingston, an American who represented President Jefferson in France, signed his name to thetreaty, he rose, shook hands with James Monroe and Marbois, the Frenchman representingNapoleon and remarked, "We have lived long, but this is the noblest work of our lives. " As weglance backward upon this important event in history, we must agree that the signing of the treatyfor the purchase of Louisiana was probably the most important event in Thomas Jeffersonsadministration. Without the acquisition of this territory, the United States would most probablyhave not developed into the powerful nation which it is today.What Causes Led to Purchase of the Louisiana TerritoryUntil 1763, Louisiana had been a possession of France, but in that year it was given to Spain torepay an old debt. Twenty years later in Paris, the treaty ending the American Revolution wassigned between the United States and Great Britain. One of the terms of this treaty was that thewestern border of the United States was to stretch to the Mississippi River. Immediately settlersand pioneers crossed westward over the Allegheny Mountains to clear the territory and establishfarms. Since roads were scarce and difficult to travel, the products of these farmers had to beshipped on the waterways leading to the Mississippi River and then down this great stream to NewOrleans. At this port city, the produce was transferred to larger ocean-going vessels andtransported to markets on the Eastern Seaboard or to Europe. However, Spains ownership ofboth shores of the river for at least two hundred miles north of New Orleans permitted this foreignnation to control the trade moving on the Mississippi. As a monarchy (君主政体) ，the Spanishgovernment distrusted the rising spirit of democracy in the United States, especially the much freerexpression of democracy that existed among the western farmers. This distrust of democracyresulted in the desire of the Spanish to deny the use of the great river to any Americans. Thereaction was instantaneous (瞬间的 ) and furious, western farmers raised their voices to protestand the United states sent John Jay to Madrid to discuss this matter. In 1795 this conflict wassettled. Spain consented to allow citizens of the United States the right to use the lower MississippiRiver and also the "right of deposit" at New Orleans, the right of deposit permitted Americanfarmers, without a duty charge, to remove their products from smaller boats at New Orleans afterhaving navigated down the Mississippi, and then to transfer the agricultural commodities to largerocean-going vessels.For the succeeding five years this agreement was observed and little conflict existed. OnOctober 1, 1800, however, Spain signed a treaty giving the ownership of the Louisiana territoryback to France. The news of this treaty did not reach Jefferson until May of the following year. Assoon as he became aware of the change in ownership of the territory, Jefferson realized that thiswas part of a plan by which Napoleon hoped to establish France as a great power in the New World.Although Napoleon still permitted Spain to remain in control of the port of New Orleans, the futurethreat to the navigation rights of the western farmers still remained. At any moment, Napoleonmight send troops to the "Gateway" and forbid Americans to use it for navigation. This wouldaffect almost forty per cent of the total export trade of the United States. By April 1802 Jeffersonsconcerns in this matter became even more intense. Napoleon had shipped armed forces to SantoDomingo to suppress the uprising. Once this had been accomplished, the troops were underorders to take possession of Louisiana with its key port city of New Orleans. On the eighteenth ofthat month the President wrote his now-famous letter to the American Minister to France, Robert R.Livingston.There is one place on the globe, one single spot, the possessor of which is our natural andhabitual enemy. It is New Orleans through which the produce of three eighths of our territorymust pass to market. . . it seals the union of two nations who in conjunction can maintainexclusive possession of the ocean. From that moment we must marry ourselves to the Britishfleet and nation.Seven months later Jefferson learned that the Spanish officials at New Orleans hadsuspended(暂不实行) the right of deposit. Immediately westernfarmers protested. Many demanded immediate action. Others pressed for a declaration ofwar. The Federalists in the East who opposed Jefferson sided with those who wished to declarewar, in order to split the ranks of his followers. In January 1803, Congress appropriated two milliondollars "to defray (支付) expenses to help improve relations between the United States and foreignnations. " Jefferson asked James Monroe to sail for France to resolve the difficulty. Monroe wasinstructed to negotiate for the purchase of New Orleans and Florida. He was permitted to offer50,000,000 francs for this concession of territory. If this offer were refused, then an alternativeoffer of 37,500,000 francs was to be made for New Orleans alone. A third alternative to be used inthe negotiation was to insist upon the permanent right of deposit at New Orleans and navigationalong the lower Mississippi. If all three offers were rejected by Napoleon, Monroe and Livingstonwere instructed to negotiate an alliance with the British Government "not to make any peace withFrance. "Why Napoleon Sold LouisianaEvents favored the United States. Napoleon had transported 35,000 troops to wipe out therebellion in Santo Domingo, but yellow fever and the rebels did away with most of the Frenchtroops. With this disaster Napoleons visions of expanding in the mainland at New Orleansvanished. He also recognized he inevitability of a conflict with Great Britain. How could he hope tokeep Louisiana, thousands of miles away across the Atlantic, as long as Britain was "Empress of theSeas"? The revenue that the sale of Louisiana would bring to.France was a temptation to Napoleon, whose treasury was almost depleted (消耗).Confronted with so many problems Napoleon quickly arrived at a decision.On April 11, 1803, evenbefore the arrival of Monroe in Paris, Talleyrand proposed that the United States purchase all of theLouisiana territory.Livingstons first offer for this "bargain" was 20, 000, 000 francs, but Talleyrandcountered with a demand for 125,000,000. In a brief negotiation both finally compromised on80,000,000 francs, equivalent to $ 15,000,000 inAmerican money.

六级阅读理解模拟练习附答案
六级阅读理解模拟练习附答案六级阅读理解模拟练习1：Recent research has claimed that an excess of positive ions in the air can have an ill effect on peoples physical or psychological health. What are positive ions? Well， the air is full of ions， electrically charged particles， and generally there is a rough balance between the positive and the negative charged. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm， earthquakes when winds such as the Mistral， Hamsin or Sharav are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing made of man-made fibres， or from TV sets， duplicators or computer display screens.When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches， fatigue， irritability，and some particularly sensitive people suffer nausea or even mental disturbance. Animals are also affected， particularly before earthquakes，snakes have been observed to come out of hibernation， rats to flee from their burrows， dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California.Conversely， when large numbers of negative ions are present， then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea， close to waterfalls or fountains， or in any place where water is sprayed， or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea， or in the mountains with tumbling streams or waterfalls.To increase the supply of negative ions indoors， some scientists recommend the use of ionisers： small portable machines， which generate negative ions. They claim that ionisers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course， there are the detractors， other scientists， who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves， or on others， of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.1.What effect does exceeding positive ionization have on some people?A.They think they are insane.B.They feel rather bad-tempered and short-fussed.C.They become violently sick.D.They are too tired to do anything.2.In accordance with the passage， static electricity can be caused by___.ing home-made electrical goods.B.wearing clothes made of natural materials.C.walking on artificial floor coverings.D.copying TV programs on a computer.3.A high negative ion count is likely to be found___.A.near a pound with a water pump.B.close to a slow-flowing river.C.high in some barren mountains.D.by a rotating water sprinkler.4.What kind of machine can generate negative ions indoors?A.Ionisers.B.Air-conditioners.C.Exhaust-fansD.Vacuum pumps.5.Some scientists believe that___.A.watching animals to anticipate earthquakes is more effective than depending on seismography.B.the unusual behavior of animals cannot be trusted.C.neither watching nor using seismographs is reliable.D.earthquake答案：BCDAA六级阅读理解模拟练习2：Once it was possible to define male and female roles easily by the division of labor. Men worked outside the home and earned the income to support their families， while women cooked the meals and took care of the home and the children. These roles were firmly fixed for most people，and there was not much opportunity for women to exchange their roles. But by the middle of this century， mens and womens roles were becoming less firmly fixed.In the 1950s， economic and social success was the goal of the typical American. But in the 1960s a new force developed called the counterculture. The people involved in this movement did not value the middle-class American goals. The counterculture presented men and women with new role choices. Taking more interest in childcare， men began to sharechild-raising tasks with their wives. In fact， some young men and women moved to communal homes or farms where the economic and childcare responsibilities were shared equally by both sexes. In addition， many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam.In terms of numbers， the counterculture was not a very large group of people. But its influence spread to many parts of American society. Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on “overtime” work so that they could spend more leisure time with theirfamilies. Some doctors， lawyers， and teachers turned away from high paying situations to practice their professions in poorer neighborhoods.In the 1970s， the feminist movement， or womens liberation， produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional womens jobs as public school teaching， nursing，and secretarial work. But some women began to enter traditionally male occupations： police work， banking， dentistry， and construction work. Women were asking for equal work， and equal opportunities for promotion.Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally， there are difficulties in adjusting to these transformations.1.Which of the following best express the main idea of Paragraph 1?A.Women usually worked outside the home for wages.B.Men and womens roles were easily exchanged in the past.C.Mens roles at home were more firmly fixed than womens.D.Men and womens roles were usually quite separated in the past.2.Which sentence best expresses the main idea of Paragraph 2?A.The first sentence.B.The second and the third sentences.C.The fourth sentence.D.The last sentence.3.In the passage the author proposes that the counterculture___.A.destroyed the United States.B.transformed some American values.C.was not important in the United States.D.brought people more leisure time with their families.4.It could be inferred from the passage that___.A.men and women will never share the same goals.B.some men will be willing to exchange their traditional male roles.C.most men will be happy to share some of the household responsibilities with their wives.D.more American households are headed by women than ever before.5.The best title for the passage may be ___.A.Results of Feminist MovementsB.New influence in American LifeC.Counterculture and Its consequenceD.Traditional Division of Male and Female Roles.答案：DCBCB。

大学英语六级阅读试题是试卷中分值最重的题型，为了提高大家的阅读水平，下面是我为大家带来英语六级阅读理解模拟练习，希望对大家的学习有所帮助!英语六级阅读理解模拟练习：能源问题It is often claimed that nuclear energy is something we cannot do without. We live in a consumer society where there is an enormous demand for commercial products of all kinds. Moreover. an increase in industrial production is considered to be one solution to the problem of mass unemployment. Such an increase presumes an abundant and cheap energy supply. Many people believe that nuclear energy provides an inexhaustible and economical source of power and chat it is therefore essential for an industrially developing society. There are a number of other advantages in the use of nuclear energy.Firstly, nuclear power. except for accidents, is clean. A further advantage is that a nuclear power station can be run and maintained by relatively few technical and administrative staff. The nuclear reactor represents an enormous step in our scientific evolution and, whatever the anti-nuclear group says, it is wrong to expect a return to more primitive sources of fuel. However, opponents of nuclear energy point out that nuclear power stations bring a direct threat not only to the environment but also to civil liberties.Furthermore, it is questionable whether ultimately nuclear power is a cheap source of energy. There have. for example. been very costly accidents in America, in Britain and, of course. in Russia. The possibility of increases in the cost of uranium(铀) in addition to the cost of greater safety provisions could price nuclear power out of the market. In the long run, environmentalists argue, nuclear energy wastes valuable resources and disturbs the ecology to an extent which could bring about the destruction of the human race. Thus, if we wish to survive. we cannot afford nuclear energy. In spice of the case against nuclear energy outlined above. nuclear energy programmes are expanding. Such an expansion assumes a continual growth in industrial production and consumer demands. However, it is doubtful whether this growth will or can continue Having weighed up the arguments on both sides, it seems there aregood economic and ecological reasons for sources of energy other than nuclear power.测试题1. The writers attitude toward nuclear energy is______________.A) indifferent B) tolerant C) favorable D) negative2. According to the opponents of nuclear energy, nuclear energy is________________.A) primitive B) cheap C) exhaustible D) unsafe3. Some people claim that nuclear energy is essentialbecause____________________.A) it provides a perfect solution to mass unemploymentB) it represents an enormous step forward in our scientific evolutionC) it can meet the growing demand of an industrially developing societyD) nuclear power stations can be run and maintained by relatively few technical and administrative staff4. Which of the following statements does the writer support?A) The demand for commercial products will not necessarily keep increasing.B) Nuclear energy is something we cannot do without.C) Uranium is a good source of energy for economic and ecologicalreasons.D) Greater safety provisions can bring about the expansion of nuclear energy programmes.5. The function of the last sentence is to___________________.A) advance the final argumentB) reflect the writers attitudeC) reverse previously expressed thoughtsD) show the disadvantages of nuclear power答案详解1.作者对于核能的看法是____。
A)漠然的 B)容忍的 C)赞成的 D)否定的[D]从文章首段第1句、第2段第1句，尤其是第2段末句，可以看出，作者对核能持否定的态度，D正确。
2.反对核能的人认为核能是________________。
A)原始的 B)便宜的 C)会枯竭的 D)不安全的[D]首段末句提到，核能反对者认为核电站不仅对环境，而且对公民自由都是一种直接的威胁，即核能不安全，D正确。
B是支持使用核能者的观点，而非作者的观点。
3.一些人声称核能是很重要的，因为_______________。
A)它为大规模失业问题提供了一个完美的解决方案B)它代表了科学革命迈向前方的一大步C)它可以满足工业发展社会不断增加的需求D)核电站可以由相对少量的技求人员和管理人员所控制和维护[C]首段第5句提到，许多人认为核能报重要，因为它是社会工业发展所必需的，可以提供取之不尽且便宜的能源，C正确。
解决大规模失业问题的一个途径是提高工业生产，而不是核能，因此A错。
C、D是支持使用核能者认为的核能的优点，与题干不构成因果关系，由此可排除。
4.作者会支持下列哪一种说法?A)对商业产品的需求不一定会不断上升。
B)核能是我们一定需要的东西。
C)铀是一种很好的能源，有着经济和生态价值。
D)更好的安全条款可以带来更多的核能项目。
[A]第2段倒数第2、3句提到，核能开发计划的扩大以工业生产和消费需求的继续增长为前提。
但是，这种增长是否能够持续，这令人怀疑，可见A正确。
B是支持使用核能者的观点。
第2段提到，铀的成本有可能提高，加上安全防范设施需要投入巨大成本，会使核能的价格超出市场承受能力，由此可同时排除C、D。
5.最后一句话的作用是______________。
A)推进最后的论点 B)反应了作者的态度C)推翻了之前的想法 D)显示出核能的弊端[B]文章最后一句表明了作者的观点，即作者认为从经济和生态环境方面来考虑。
