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. On April 30, 1803, Louisiana became the possession of the United States.Three-fourths of the sum went to France, the balance was reserved to pay the claims of Americancitizens against France.1.

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。
英语六级阅读理解练习5篇(附答案)二
英语六级阅读理解练习6篇（附答案）二第一篇Pronouncing a language is a skill. Every normal person is expert in the skill of pronouncing his own language; but few people are even moderately proficient at pronouncing foreign languages. Now there are many reasons for this, some obvious, some perhaps not so obvious. But I suggest that the fundamental reason why people in general do not speak foreign languages very much better than they do is that they fail to grasp the true nature of the problem of learning to pronounce, and consequently never set about tackling it in the right way. Far too many people fail to realize that pronouncing a foreign language is a skill—one that needs careful training of a special kind, and one that cannot be acquired by just leaving it to take care of itself. I think even teachers of language, while recognizing the importance of a good accent, tend to neglect, in their practical teaching, the branch of study concerned with speaking the language. So the first point I want to make is that English pronunciation must be taught; the teacher should be prepared to devote some of the lesson time to this, and should get the student to feel that here is a matter worthy of receiving his close attention. So, there should be occasions when other aspects of English, such as grammar or spelling, are allowed for the moment to take second place.Apart from this question of the time given to pronunciation, there are two other requirements for the teacher: the first, knowledge; the second, technique.It is important that the teacher should be in possession of the necessary information. This can generally be obtained from books. It is possible to get from books some idea of the mechanics of speech, and of what we call general phonetic theory. It is also possible in this way to get a clear mental picture of the relationship between the sounds of different languages, between the speech habits of English people and those, say, of your students. Unless the teacher has such a picture, any comments he may make on his students' pronunciation are unlikely to be of much use, and lesson time spent on pronunciation may well be time wasted.1. What does the writer actually say about pronouncing foreign languages?A. Only a few people are really proficient.B. No one is really an expert in the skill.C. There aren't many people who are even fairly good.D. There are even some people who are moderately proficient.2. The writer argues that going about the problem of pronunciation in the wrong way isA. an obvious cause of not grasping the problem correctlyB. a fundamental consequence of not speaking wellC. a consequence of not grasping the problem correctlyD. not an obvious cause of speaking poorly3. The best way of learning to speak a foreign language, he suggests, is by_______.A. picking it up naturally as a childB. learning from a native speakerC. not concentrating on pronunciation as suchD. undertaking systematic work4. The value the student puts on correct speech habits depends upon_______.A. how closely he attends to the matterB. whether it is English that is being taughtC. his teacher's approach to pronunciationD. the importance normally given to grammar and spelling5. How might the teacher find himself wasting lesson time?A. By spending lesson time on pronunciation.B. By making ill-informed comments upon pronunciation.C. By not using books on phonetics in the classroom.D. By not giving students a clear mental picture of the difference between sounds.第二篇An industrial society, especially one as centralized and concentrated as that of Britain, is heavily dependant on certain essential services: for instance, electricity supply, water, rail and road transport, the harbors. The area of dependency has widened to include removing rubbish, hospital and ambulance services, and, as the economy develops, central computer and information services as well. If any of these services ceases to operate, the whole economic system is in danger.It is this interdependency of the economic system that makes the power of trade unions such an important issue. Single trade unions have the ability to cut off many economic blood supplies. This can happen more easily in Britain than in some other countries, in part because the labor force is highly organized. About 55 per cent of British workers belong to unions, compared to under a quarter in the United States. For historical reasons, Britain's unions have tended to develop along trade and occupational lines, rather than on an industry-by-industry basis, which makes wage policy, democracy in industry and the improvement of procedures for fixing wage levels difficult to achieve.There are considerable strains and tensions in the trade union movement, some of them arising from their outdated and inefficient structure. Some unions have lost many members because of industrial changes. Others are involved in arguments about who should represent workers in new trades. Unions for skilled trades are separate from general unions, which means that different levels of wages for certain jobs areoften a source of bad feeling between unions. In traditional trades which are being pushed out of existence by advancing technologies, unions can fight for their members' disappearing jobs to the point where the jobs of other union's members are threatened or destroyed. The printing of newspapers both in the United States and in Britain has frequently been halted by the efforts of printers to hold on to their traditional highly-paid jobs.1. Why is the question of trade union power important in Britain?A. The economy is very much interdependent.B. Unions have been established a long time.C. There are more unions in Britain than elsewhere.D. There are many essential services.2. Because of their out-of-date organization some unions find it difficult to______.A. change as industries changeB. get new members to join themC. learn new technologiesD. bargain for high enough wages3. Disagreements arise between unions because some of themA. try to win over members of other unionsB. ignore agreementsC. protect their own members at the expense of othersD. take over other union's jobs4. It is difficult to improve the procedures for fixing wage levels because______.A. some industries have no unionsB. unions are not organized according to industriesC. only 55 per cent of workers belong to unionsD. some unions are too powerful5. Which of the following is NOT TRUE?A. There are strains and tensions in the trade union movement.B. Some unions have lost many members.C. Some unions exist in the outdated structure.D. A higher percentage of American workers belong to unions than that of British workers.第三篇Although credit cards are becoming a more acceptable part of the financial scene, they are still regarded with suspicion by many as being a major part of the "live now pay later" syndrome(^Jttt). Along with hire-purchase, rental and leasing schemes, they provide encouragement to spend more money. Of course, it is only the foolhardy who yield to the temptation to live, temporarily at least, beyond their means, and suchpeople would no doubt manage to do so even without credit cards.Advertising campaigns have, however, promoted a growing realization of the advantages of these small pieces of plastic. They obviate (避免) need to carry large amounts of cash and are always useful in emergencies.All the credit card organizations charge interest on a monthly basis which may work out as high as 25 per cent a year, yet judicious purchasing using a card can mean that you obtain up to seven weeks, interest-free credit. Using the card abroad, where items frequently take a long time to be included on your account, can extend this period even further.It is worthwhile shopping around before deciding on a particular credit card. It is necessary to consider the amount of credit granted; interest rates, which may vary slightly; the number and range of outlets, though most cards cover major garages, hotels, restaurants and department stores; and of course, what happens if your card is lost or stolen. A credit card thief may be sitting on a potential goldmine particularly if there is a delay in reporting the loss of the card.However, if used wisely, a credit card can cost nothing, or at least help to tide you over a period of financial difficulty.1. Which of the following can not make you spend more money?A. Credit cards.B. Hire-purchase.C. Rental and leasing schemes.D. None of the above is right.2. The foolhardy are people who_______.A. spend more money than they haveB. spend less money than other peopleC. save moneyD. make money3. The disadvantage of credit cards is_______.A. to enable you to buy things without carrying large amount of cashB. to encourage people to spend more moneyC. to be always useful in emergenciesD. to help people tide over a period of financial difficulty4. According to the passage, credit cards are made of_______.A. paperB. goldC. plasticD. tin5. Deciding on a particular credit, you do not have to consider______.A. the amount of credit grantedB. the number and range of outletsC. the possibility of loss of moneyD. the department stores where you are going to use your credit cards第四篇More attention was paid to the quality of production in France at the time of Rene Coty. Charles Deschanel was then the financial minister. He stressed that workmanship and quality were more important than quantity for industrial production. It would be necessary to produce quality goods for the international markets tocompete with those produced in other countries. The French economy needed a larger share of international market to balance its import and export trade.French industrial and agricultural production was still inadequate to meet the immediate needs of the people, let alone long-ranged developments. Essential imports had stretched the national credit to the breaking point. Rents were tightly controlled, but the extreme inflation affected general population most severely through the cost of food. Food costs took as much as 80 percent of the worker's income. Wages, it is true, had risen. Extensive family allowances and benefits were paid by the state, and there was fulltime and overtime employment. Taken together, these factors enabled the working class to exist but allowed them no sense of security. In this discouraging situation, workmen were willing to work overseas for higher wages.The government was unwilling to let workers leave the country. It was feared that migration of workers would reduce the labor force. The lack of qualified workers might hinder the improvement in the quality of industrial products produced. Qualified workers employed abroad would only increase the quantity of quality goods produced in foreign countries. Also the quantity of quality goods produced in France would not be able to increase as part of its ualified labor force moved to other countries.1. The purpose of the passage is to_______.A. explain the French government's emphasis on quality productsB. discuss Charles Deschanel's contribution to the French industrial developmentC. compare the quality of French goods with that of foreign goodsD. show French workmen's enthusiasm to seek well-paid jobs in foreign countries2. It can be inferred from the passage that at the time of Rene Coty .A. France was still at the first stage of industrial developmentB. French workers were better paid than the workers in any other European countriesC. the unemployment rate in France was comparatively higher than that in other European countriesD. French workers were able to live better with the increase in their wages3. It is implied in the passage that at that time_______.A. France had a very large share of international marketB. the import and export trade in France was making a successful advanceC. demand and supply in France was barely balancedD. France was experiencing economic depression4. Which of the following is the best indicator of the extreme inflation in France?A. Eighty percent increase in the prices of consumer goods.B. High cost of food.C. High rents for houses.D. Lack of agricultural products.5. Which of the following is NOT mentioned in the passage?A. Rents in France were tightly controlled.B. France was flooding the international market with inferior products.C. French workers were prohibited from going abroad to find jobs.D. The migration of French workers would hinder the improvement of quality in industrial production.第五篇As a company executive(总经理) who spent ten years in federal service, I am often asked what I regard as the biggest difference between working for the government and working for a private company. My invariable response is to say that I look back on my time in government as one of the most exciting and challenging experiences of my life. Furthermore, I never worked as hard as when I was a public servant.When I worked for the government, I worked with some of the finest, most competent and most committed people I have ever met. I was impressed by the overall quality of our career civil servants then, and I still am. But one of my greatest concerns now is that I will not be able to hold this same high opinion in the future.Career public servants are leaving government in alarming numbers, and qualified replacements are becoming harder and harder to find. Good people who leave career government service are striving for highly paid positions in private enterprises.We depend on government to keep this country safe in an uncertain world, to secure justice and domestic order and to solve a host of pressing problems. We need the best possible people performing and overseeing these vital tasks. A high-quality, professional federal service has been a source of national pride for more than a century. But what we have built up during a hundred years can be lost in less time than we imagine. We can't afford to let this happen. We must act now if this country is to be assured of the quality public service it deserves.1. Career public servants are leaving government in alarming numbers. One of thereasons may be that______.A. they received lower payB. they deserved no fame and gloryC. they performed poorlyD. they worked harder than anyone else2. According to the author, _______, so I will not be able to hold this same high opiniontoward the public servants in the future.A. I never worked as hard as when I was a public servantB. I have become a company executiveC. there will not be so many competent and qualified servants in the government as we had beforeD. my time in government was not the most exciting experience in my life3. We depend on government to keep this country safe in an uncertain world, therefore,A. we should make greater contributions to the countryB. the best possible people are urgently needed to do important tasksC. we should show deep concern about the nation's futureD. we should become public servants4. If we neglect the serious problem and make no efforts, we will lose_______.A. national prideB. high-quality professional federal serviceC. good peopleD. private enterprise5. Which of the following is NOT TRUE?A. Those who work for companies are highly paid.B. More and more public servants have left the government.C. Career public servants are qualified.D. Many people of high qualities want to work in the government.According to the latest research in the' United States of America, men and women talk such different languages that it is like people from two different cultures trying to communicate. Professor Deborah Tannen of Georgetown University, has noticed the difference in the style of boy's and girl's conversations from an early age. She says that little girls' conversation is less definite than boys' and expresses more doubts. Little boys use conversation to establish status with their listeners.These differences continue into adult life, she says. In public conversations, men talk most and interrupt other speakers more. In private conversations, men and women speak in equal amounts—although they say things in a different style. Professor Tannen believes that, for woman, private talking is a way to establish and test intimacy. For men, private talking is a way to explore the power structure of a relationship.第六篇Teaching is one job where the differences between men's and women's ways of talking show. When a man teaches a woman, says Professor Tannen, he wants to show that he has more knowledge, and hence more power in conversation. When a woman teaches another woman, however, she is more likely to take a sharing approach and to encourage her student to join in.But Professor Tannen does not believe that women are naturally more helpful. She says women feel they achieve power by being able to help others. Although the research suggests men talk and interrupt people more than women, Professor Tannen says, women actually encourage this to happen because they believe it will lead to more intimacy and help to establish a relationship.Some scientists who are studying speech think that the brain is pre¬programmedfor language. As we are usually taught to speak by women, it seems likely that the brain must have a sexual bias(倾向性) in its programming,otherwise male speech patterns would not arise at all.1. In the opinion of the writer, women encourage men to talk becauseA. it will lead to more intimacy and help to establish a relationshipB. it will help to establish status with their listenersC. it will help to express more clearlyD. it will help to communicate better2. There are_______in little girls' conversation than in boys'.A. fewer doubtsB. more demandsC. more doubtsD. fewer uncertainties3. Some scientists believe that brain is pre-programmed for language. The word "pre programmed" means_______.A. programmed alreadyB. programmed before one is bornC. programmed earlyD. programmed by women4. In private conversation, women speakA. the same things as menB. less than menC. more than menD. as much as men5. The theme of this article is _______.A. women are naturally more helpfulB. men and women talk different languagesC. men talk most and interrupt other speakers moreD. little girls' conversation is less definite第一篇答案、1.

What defines an empire and what does the building of empire suggested? The regions of Mesopotamia, Egypt(the Nile Valley), and the Indus Valley are three rich areas for studying how people and ideas come together to create civilizations and empires. Imagine three spaces that are sparsely populated, yet well watered and fertile, in a time before written history. Two are river valleys, another lies between two rivers forming a rich plain. Imagine that humans settle in these regions and domesticate plants and animals. The domestication made possible by these river territories and the success of that domestication —farming and grazing —lure increasingly greater human and animal migration to these spaces. As these populations increase, so do their needs. These needs give rise to the social and political economic formations that characterize the ancient urban spaces and states of Mesopotamia, the Indus and Nile valleys. Mesopotamian, Egyptian, and Indus Valley civilizations are noted for their dense populations, urbanization processes, and cultural innovation. These elements are tied to the growth of commerce and broader cultural interaction. That is, as empires these civilizations can be thought of as collections of peoples, goods, and ideas whose existence and dynamism were built on movement and exchange. The initial formation of these civilizations is based on the movement of peoples into the river valleys and plains. They often described their environments as god-like and characterized their nearby rivers as life-giving. The transformation of these valleys and plains into places capable of physically nurturing the various peoples who moved into them was one of the first acts of cultural innovation and exchange. The use of these valleys’soil and water was signs of innovation and exchange. For the Mesopotamians, the key to making the land fertile was the technology of irrigation. In fact, irrigation became the key feature of the civilization. As a result of the need for irrigation, religious and legal codes in many Mesopotamian societies focused on water use. Egypt and the Nile Valley civilizations were defined by the rich alluvial soils(冲击土)that annual floods deposited along the Nile banks and in the delta and flood plains. The use of water and the timing of flood seasons gave rise to a number of technological innovations, such as the calendar. These cultural and technologicalinnovations also guaranteed the growth of large populations and increased the possibility that some of those populations would be located in central urban centers. These societies’agricultural and ecological technologies drew immigrants and travelers who often brought foods and ideas that contributed to the culture of these civilizations. The ability of these areas to sustain population —an ability that can be thought of as a richness—attracted more peoples. Some of these people entered the areas peaceably. Others used force to maintain or expand geographic and cultural spaces, indicating imperial activity. An interesting pattern emerging here in some urban centers was constructed to protect against invading forces, and seen in the walled settlements of the Indus Valley and early Mesopotamia. However, as much as these walled settlements repelled invaders, they also attracted them. The river valleys and the plains, and their agricultural richness, supported the formation of cities. The cities became emblems of their respective empires and either allowed for the extension of the empire or resisted the threats of other powers. The historical activities of the Indus Valley, Mesopotamia, and Egypt indicate that various peoples moved in and out, contested the regions’ spaces, and sought to control other peoples, their goods and their resources. This interaction had profound consequences on how those involved thought about themselves and each other. Their ideas were tested, challenged, and in many instances, changed. These regions’ cities probably were seen as symbols of wealth; therefore, groups in and outside of the region often sought to control them. Richness is understood as the population’s ability to produce goods and services in quantity not just agriculture, but skills such as metal working, pottery, or commerce. Thus, richness in population meant surpluses allowed the cities and the areas they controlled to support a ruling and administrative class, and maybe an army. Frequently, product surpluses were exchanged, providing wealth for the area and drawing other peoples to it. The Indus Valley, Mesopotamia, and Egypt all experienced the results of a rich and productive population. New language patterns, such as the early substitution of the Akkadian tongue for Sumerian, demonstrate the innovations encouraged by movement and exchange. The gathering of peoples, languages, and cultures was part of the creation of a world view, though, a limited one. By 700 BC, the extent of the Assyrian Empire literally limited it to the activities of the Egyptian quest for empire status. That linkage can be expressed as interaction and exchange. Diplomatic exchange as well as military struggle resolved conflict over the empires’boundaries and areas of control. Marriage was a highly visible form of diplomacy and amounted to an exchange between ruling families that linked them politically and economically. These arrangements often resulted in the cessation of hostilities, greater regional stability, and greater economic exchange. Marriages across the ruling classes of these societies offer one way to conceptualize the world. Political marriages and royal hostages both provided for the sharing of culture across religious and ethnic divisions and differences that may well have contributed to humankind’s history. Movement and interaction also are seen in the clash of armies, which may have meant technological and cultural innovation. For instance, many historians believe that the clash between the Hyksos and Egyptians resulted in the exchange of important military innovations for the Egyptians. Throughthis conflict, the Egyptians discovered the advantages of iron weaponry over bronze and the superiority of the chariot(二轮战车)as an assault weapon. Within the movement and exchange that epitomized(集中体现)the Indus, Meso-potamian, and Nile civilizations, rising empires imposed a stability that occasionally resulted in greater interaction between states and peoples because of the inherent security of the empire. The most striking example of this greater interaction is trade. Many scholars argue that the collection of peoples in certain areas and changes in demographic(人口的)concentration are related to patterns of trade. Urban growth can be explained by looking at the spaces where trade was possible and the ways in which that trade might have drawn together people and their goods or services. Those spaces necessitated some authority to provide order and security. The goods and security offered by these urban spaces lured the merchants not only to travel from place to place carrying goods and ideas but also often to become residents in distant places, establishing new communities within communities. At times, some of these merchants served as ambassadors. They presented information that was important to maintaining good relations between their home societies and those they adopted through trade. We might select any of the remarkable points of these three areas and see them replicated in some form across the others. The reason for this replication, and its differences, reiterates(重申)that the establishment of empires, and the civilizations they represented, was not the creation of discrete imperial space so much as a way of ordering interaction between possible discrete spaces. The structures of these civilizations—these empires, states, cities —did not stop the interaction and the flow of goods, people, and ideas. On the contrary, they encouraged it. That encouragement resulted in the earliest formations of what has been called the Afro-Eurasian Old World —the interaction between the Indus, Mesopotamian, and Nile river systems.1．Which of the following is a remarkable feature of Mesopotamian, Egyptian, and Indus Valley civilizations?A．Fertile soil and abundant water resources.B．Sparse population.C．Broader cultural interaction.D．Cultural innovation.正确答案：D解析：第一句说这三大文明以其人口密集、城市化进程和文化创新而闻名。

大学英语六级阅读理解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，希望对大家的学习有所帮助!英语六级长篇阅读模拟练习：Daylight Saving Time (DST) How and When Did Daylight Saving Time Start?A. Benjamin Franklin--of "early to bed and early to rise"fame--was apparently the first person to suggest the concept of daylight savings. While serving as U.S. ambassador to France in Pads, Franklin wrote of being awakened at 6 a.m. and realizing, to his surprise, that the sun would rise far earlier than he usually did. Imagine the resources that might be saved if he and others rose before noon and burned less midnight oil, Franklin, tongue half in cheek, wrote to a newspaper.B. It wasnt until World War I that daylight savings were realized on a grand scale. Germany was the first state to adopt the time changes, to reduce artificial lighting and thereby save coal for the war effort. Friends and foes soon followed suit. In the U.S.a federal law standardized the yearly start and end of daylight saving time in 1918--for the states that chose to observe it.C. During World War II the U.S. made daylight saving time mandatory(强制的) for the whole country, as a way to save wartime resources. Between February 9, 1942, and September 30, 1945, the government took it a step further. During this period daylight saving time was observed year-round, essentially making it the new standard time, if only for a few years. Many years later, the Energy Policy Act of 2005 was enacted, mandating a controversial month-long extension of daylight saving time, starting in 2007.Daylight Saving Time: Energy Saver or Just Time Sucker?D. In recent years several studies have suggested that daylight saving time doesnt actually save energy--and might even result in a net loss. Environmental economist Hendrik Wolff, of the University of Washington, co- authored a paper that studied Australian power-use data when parts of the country extended daylight saving time for the 2000 Sydney Olympics and others did not. The researchers found that the practice reduced lighting and electricityconsumption in the evening but increased energy use in the now dark mornings-- wiping out the evening gains. Thats because the extra hour that daylight saving time adds in the evening is a hotter hour. "So if people get home an hour earlier in a wanner house, they turn on their air conditioning," the University of Washingtons Wolff said.E. But other studies do show energy gains. In an October 2008 daylight saving time report to Congress, mandated by the same 2005 energy act that extended daylight saving time, the U.S. Department of Energy asserted that springing forward does save energy. Extended daylight saving time saved 1.3 terawatt ( 太瓦 ) hours of electricity. That figure suggests that daylight saving time reduces annual U.S. electricity consumption by 0.03 percent and overall energy consumption by 0.02 percent. While those percentages seem small, they could represent significant savings because of the nations enormous total energy use.F. Whats more, savings in some regions are apparently greater than in others. California, for instance, appears to benefit most from daylight saving time--perhaps because its relatively mild weather encourages people to stay outdoors later. The Energy Department report found that daylight saving time resulted in an energy savings of one percent daily in the state.G. But Wolff, one of many scholars who contributed to the federal report, suggested that the numbers were subject to statistical variability ( 变化) and shouldnt be taken as hard facts. And daylight savings energy gains in the U.S. largely depend on your location in relation to the Mason-Dixon Line, Wolff said."The North might be a slight winner, because the North doesnt have as much air conditioning," he said. "But the South is a definite loser in terms of energy consumption. The South has more energy consumption under daylight saving."Daylight Saving Time: Healthy or Harmful?H. For decades advocates of daylight savings have argued that, energy savings or no, daylight saving time boosts health by encouraging active lifestyles--a claim Wolff and colleagues are currently putting to the test. "In a nationwide American time-use study, were clearly seeing that, at the time of daylight saving time extension in the spring, television watching is substantially reduced and outdoor behaviors like jogging, walking, or going to the park are substantially increased," Wolff said. "Thats remarkable, because of course the total amount of daylight in a given day is the same. "I. But others warn of ill effects. Till Roenneberg, a university professor in Munich (慕尼黑), Germany, said his studies show thatour circadian (生理节奏的 ) body clocks--set by light and darkness--never adjust to gaining an "extra" hour of sunlight to the end of the day during daylight saving time.J. One reason so many people in the developed world are chronically (长期地) overtired, he said, is that they suffer from"social jet lag. "In other words, their optimal circadian sleep periods dont accord with their actual sleep schedules. Shifting daylight from morning to evening only increases this lag, he said. "Light doesnt do the same things to the body in the morning and the evening. More light in the morning would advance the body clock, and that would be good. But more light in the evening would even further delay the body clock. "K. Other research hints at even more serious health risks. A 2008 study concluded that, at least in Sweden, heart attack risks go up in the days just after the spring time change. "The most likely explanation to our findings is disturbed sleep and disruption of biological rhythms," One expert told National Geographic News via email.Daylight Savings Lovers and HatersL. With verdicts (定论) on the benefits, or costs, of daylight savings so split, it may be no surprise that the yearly time changes inspire polarized reactions. In the U.K., for instance, the LighterLater movement--part of 10:10,a group advocating cutting carbon emissions--argues for a sort of extreme daylight savings. First, they say,move standard time forward an hour, then keep observing daylight saving time as usual--adding two hours ofevening daylight to what we currently consider standard time. The folks behind Standardtime, on the other hand, want to abolish daylight saving time altogether, calling energy-efficiency claims "unproven. "M. National telephone surveys by Rasmussen Reports from spring 2010 and fall 2009 deliver the same answer.Most people just "dont think the time change is worth the hassle (麻烦的事 ). " Forty-seven percent agreedwith that statement, while only 40 percent disagreed. But Seize the Daylight author David Prerau said his research on daylight saving time suggests most people are fond of it."I think if you ask most people if they enjoy having an extra hour of daylight in the evening eight months a year, the response would be pretty positive."46. Daylight savings energy gains might be various due to different climates.47. Disturbed sleep and disruption of biological rhythms may be the best explanation to higher heart attack risks in the days after the spring time change.48. A research indicated that DST might not save energy byincreasing energy use in the dark mornings, though it reduced lighting and electricity consumption in the evening.49. Germany took the lead in saving wardme resources by adopting the time changes and reducing artificiallighting.50. A university professor studied the effect of daylight saving time and sounded the alarm of its negative effects.51. Social jet lag can partly account for peoples chronic fatigue syndrome in developed countries.52. The figure of a study in the U.S. suggested that DST could save a lot of energy nationally.53. Supporters of daylight savings have long considered daylight saving time does good to peoples health.54. A group advocating cutting carbon emissions launches the Lighter Later movement to back a kind of extreme daylight savings.55. A scholar contributing to a federal report suggested that the amount of saved energy had something to do with geographic position.【参考译文】夏令时夏令时是如何开始的?何时开始的?A.享有"早睡早起"声誉的本杰明富兰克林显然是提出夏令时这一理念的第一人。

大学英语六级（阅读）模拟试卷18(题后含答案及解析) 题型有： 4. Reading Comprehension (Reading in Depth)Part IV Reading Comprehension (Reading in Depth) (25 minutes)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.The news about the world’s oceans in 2003 wasn’t that they’re in trouble —that much was already clear —but that the scale of devastation is far greater than anyone had realized. A shocking study revealed that a full 90 percent of the species most desirable to fishmongers(鱼商)—tuna, halibut, sharks, swordfish, grouper —has been wiped out in the past half century. But there was hopeful news as well. An alternative to conventional fishing practices, while not a cure-all(万灵药), could significantly restore ravaged fish populations. The chilling centerpiece of last year’s marine research: just 50 years of industrial fishing has decimated(大批杀害)the world’s large predator(食肉动物)fish species, according to a report published in Nature in May. Irresponsible fishing practices have resulted severe casualties: Shrimp trawling(拖网捕捞)in the Gulf of Mexico, for example, a reckless process in which, for every ton of shrimp obtained, three tons of fin-fish(长须鲸)are destroyed and discarded —has shrunk large fish stocks a thousandfold. “Across the board we’ve removed everything bigger than a bicycle from the o-cean,”says Steve Palumbi, a Stanford University biologist, “and that has almost certainly changed the ocean in fundamental ways. “But the urgent need for large-scale conservation efforts is on a collision course with economic pressures to expand fishing even further, according to a 2003 report by the Pew Oceans Commission, an independent expert panel, as well as preliminary reports from members of the Bush-appointed U. S. commission on Ocean Policy. Americans are eating more seafood than ever: Consumption was up 7 percent in 2002, to 4. 5 billion pounds. Worldwide, more than 130 billion pounds of marine species are caught annually, and that doesn’t include the huge amount of sea life destroyed as by-catch. More than a billion people rely on fish for protein. “ We need to change the whole ethic of how we are viewing the oceans,”says Andrew Rosenberg, a member of the Commission on Ocean Policy, “ from a place that we use to a place we care for. “In September marine biologists Fiona Gell and Callum Roberts of the University of York in England offered a solution, boldly asserting that at least 30 percent of the world’s ocean habitat had to become safe zones for marine life. It’s a practical, not a sentimental matter, they contend. After studying 60 no-fishing zones around the world, Gell and Roberts discovered that the fish there live longer, grow larger, and produce more young than those in unprotected areas. Significantly, as populations growing, many fish head into less crowded areas outside the reserve, where fishermen reap the benefits indefinitely. “It’s a no-brainer(无需用脑的事), really, isn’t it?”Roberts observes. “Like money in the bank producing interest. “1．What’s the news about the oceans in 2003?A．People ignore what the oceans are suffering.B．The scale of the ocean devastation is out of our expectation.C．The fishmongers are making effort to improve their fishing practices.D．The oceans are losing many rare species.正确答案：B解析：事实细节题。

英语六级阅读理解模拟练习附参考答案
英语六级阅读理解模拟练习附参考答案六级阅读理解模拟练习一：The Look Younger DietIs the Fountain of Youth a myth? Not entirely,many experts in nutrition now believe, "Age fast, orage slow—it's up to you. " declares Dr. KennethCooper, president and founder of the Aerobics Centerin Dallas. Jeffrey Blumberg, associate director ofthe U. S. Department of Agriculture's HumanNutrition Research Center on Aging at TuftsUniversity in Boston, agrees, " Research shows that many so-called age-related declines inphysiological function seem to have less to do with aging than with environmental factors likediet and exercise. "Obesity 过度肥胖 is one of the leading causes of accelerated aging, according to Cooper, "Ifyou lose weight, stop smoking, and exercise," he says, "you can slow the aging process—andmake dramatic changes in your looks in a relatively short period of time. "A 37-year-old sales director for a Boston computer-distribution company is a primeexample. Over six feet tall, he had been considerably overweight most of his like. Then hebegan to worry that his appearance could be hurting his career. "I got tired of people thinkingI was the same age as my brother, who's nearly nine years older," he says, "When you're fat,people in the business world assume you're out of control. "Determined to change, the sales director entered a hospital-based diet program anddropped over 70 pounds. "I feel—and look—ten years younger. " he says.At 82, Clarice R. Mc Williams, a retired business owner in Dallas, has the appearance, skintone 肤色 and mental agility of someone many years younger. "Most people think I'm in my60s. " she boasts.Mc Williams admits genes play some role in the way she looks, but believes diet is animportant factor. "It doesn't matter how good the genes are if you don't eat properly and takecare of yourself," she says. "If you want to look good, get plenty of rest, exercise every day, eatmostly raw fruits and vegetables—and quit worrying. "Says Blumberg, "There's certainly a link between good nutrition, apositive attitude andimproved quality of life. People can have a say in what's going on with their bodies by selectinga healthful diet. "Skin. Nowhere do the signs of aging manifest themselves more clearly than in thecondition of the skin. When your weight fluctuates, the skin stretches with each up cycle, but itmay not completely shrink back to its original size in the down cycle. As a result, the skin maysag松弛下垂.A severely deficient diet can lead to skin disorders, dramatically affecting one'sappearance. By the same token, a well-balanced diet with ample supplies of nutrients isthought by many experts to produce a glowing, younger look.Zinc and vitamin A are important for normal, healthy skin. Zinc helps the skin repair itself,and vitamin A aids in keeping skin supple, preventing dryness and helping shed dead cells.Good sources of zinc are beef, eggs and seafood, while many dark-green leafy vegetables arerich in beta carotene, which the body converts to vitamin A. Other foods containing ampleamounts of beta carotene include carrots, cantaloupe, winter squash, sweet potatoes, sweet redpeppers, apricots and mangoes.Vitamin C helps improve the blood supply to the skin and aids in forming collagen胶原 ,the fibrous protein that lies beneath the skin's surface and gives it a smooth appearance.Good sources of vitamin C include citrus fruits and juices, Brussels sprouts, cauliflower, snowpeas, red and green peppers, broccoli, white and sweet potatoes, tomatoes, watermelon,honeydew melon and cantaloupe.Greens are excellent sources of skin-preserving nutrients and, generally, the darker theleaves, the more nutritious. Romaine lettuce, for example has about six times as muchvitamin C and eight times as much beta carotene as iceberg lettuce.How food is prepared matters too. The longer vegetables cook, the greater the loss ofvitamins and texture. Don't soak vegetables when washing them, since water-soluble vitaminssuch as C will be lost.Blumberg also recommends drinking six to eight glasses of water or other fluids each day tohelp keep skin and other tissues hydrated. "That'sespecially important for older people," hesays, "who are at risk for dehydration because their thirst drive becomes blunted with age. "Coffee,colas and tea aren't the best sources, since they contain caffeine, a diuretic thatinduces water loss.Hair. Healthy, shining hair is second only to vibrant skin for making one look younger. Yetmany people unwittingly mistreat their hair by eating an unbalanced diet.When a 33-year-old employee at a Texas corporation decided to lose weight quickly, shewent on a fad diet, high in fiber and bulk, but low in protein. Over three months, she lost a lotof weight. She also lost a good deal of her hair.Dermatologist 皮肤病学家 David Alkek, a clinical professor at the University of TexasSouthwest Medical Center at Dallas, sees too many caseslike this woman's. When diets don'tcontain enough amino acids, the building blocks of protein, there's dramatic increase in hairloss as the body breaks down its own protein.Hair and skin cells are constantly reproducing and are, therefore, very sensitive tonutritional deficiencies, explains Dr. Alkek. Foods high in amino acids include meats, eggs, milk,grains and legumes. Just remember that the body cannot store protein. So foods high inprotein must be ingested daily. Under Alkek's care, the woman began eating nutritionallybalanced meals, and her hair was restored in about eight months.Immune system. Vitamins E and C and beta carotene, known as antioxidants 抗氧化剂 ,are considered powerful disease-fighters, capable of slowing down or preventing a number ofailments typically associated with aging.A growing body of evidence suggests that aging and decline in immune function mayresult in part from accumulated damage to cells caused by certain toxic compounds called freeradicals 自由基. Antioxidants seem to counteract or impair the ability of these substances toattack healthy cells, thus avoiding at least some of the damage. Foods containing thesenutrients are being linked—by science rather than myth—to the control and prevention ofheart disease and cancer, stroke, cataracts and to the body's ability to ward off infectiousdiseases.Good general nutrition is essential to maintaining a healthy, youthful appearance. Andthe key to good general nutrition is balance. Proteins should make up roughly ten percent ofyour daily calorie intake; no more than 30percent should come from fats; and the remainingcalories should come mostly from complex carbohydrates.1. The passage primarily tells us how to lose weight so as to improveone's appearance.2. Dark-green leafy vegetables are good sources of beta carotene.3. When one gains weight, the skin becomes loose.4. It is particularly important for the old to drink 6 to 8 glasses of water to help keep skinand other tissues hydrated.5. Food low in protein is harmful to hair.6. Free radicals play an important role in immune function.7. In order to look younger, one should cut back on fats.8. Amino acids are the building blocks of______.9. Genes are______than diet in determining one's looks.10. The body changes______into vitamin A.参考答案：1. N2. Y3. N4. Y5. Y6. N7. NG8. protein9.less important 10. beta carotene六级阅读理解模拟练习二：As we know, it is very important that a firmshould pay attention to the training of its staff asthere exist many weak parts in its variousdepartments. Staff training must have a purpose,which is defined when a firm considers its trainingneeds, which are in turn based on job descriptionsand job specifications.A job description should give details of theperformance that is requiredfor a particular job, and a job specification should giveinformation about the behavior, knowledge and skills that are expected of an employee whoworks in it. When all of this has been collected, it is possible to make a training specification.This specifies what the Training Department must teach for the successful performance of thejob, and also the best methods to use in the training period.There are many different training methods, and there are advantages and disadvantages ofall of them. Successful training programmes depend on an understanding of the differencebetween learning about skills and training in using them. It is frequently said that learningabout skills takes place "off the job" in the classroom, but training in using these skills takesplace "on the job", by means of such activities as practice in the workshop.It is always difficult to evaluate the costs and savings of a training programme. Thesuccess of such a programme depends not only on the methods used but also on the quality ofthe staff who do the training. A company can often check oh savings in time and cost byexamining the work performed by the workers and technicians who have completed a trainingprogramme. The evaluation of management training is much more complex than that.21. To be successful in our training programmes, we must understand the differencebetween______.A. a job description and a job specificationB. what is taught and how it is taughtC. learning about skills and training in using themD. the savings in time and the savings in cost22. The success of a training programme depends on_________.A. the places where the training takes placeB. the correct evaluation of the costs and savings of the programmeC. the performance of the workers and technicians trained in the programmeD. the training methods and the quality of the training staff23. A training specification specifies_______.A. the performance required for a certain jobB. the behavior, knowledge, and skills expected of an employeeC. the training contents and methodsD. the costs and savings of the programme24. According to the passage, which of the following statements is NOT true?A. As there exist weak parts in different departments of a firm, the training of its staff ishighly necessary.B. A training specification is based on the information collected from a job descriptionand a job specification.C. Training in using skills and learning about skills usually do not happen at the same place.D. It is easier to evaluate management training than to evaluate the training of workersand technicians.25. The best title for this passage might be_______.A. A Successful Training ProgrammeB. How to Describe and Specify a JobC. Staff TrainingD. The Importance of Training Workers and Technicians参考答案：21.

We live in a consumer society where there is an enormous demandfor commercial products of all kinds. Moreover. an increase in industrialproduction is considered to be one solution to the problem of mass unemployment. Such an increase presumes an abundant and cheap energysupply. Many people believe that nuclear energy provides an inexhaustibleand economical source of power and chat it is therefore essential for anindustrially developing society. There are a number of other advantages inthe use of nuclear energy. Firstly, nuclear power. except for accidents, isclean. A further advantage is that a nuclear power station can be run andmaintained by relatively few technical and administrative staff. The nuclearreactor represents an enormous step in our scientific evolution and, whateverthe anti-nuclear group says, it is wrong to expect a return to more primitivesources of fuel. However, opponents of nuclear energy point out that nuclearpower stations bring a direct threat not only to the environment but also tocivil liberties.Furthermore, it is questionable whether ultimately nuclear power is acheap source of energy. There have. for example. been very costly accidents。

大学英语六级（阅读）模拟试卷10(题后含答案及解析) 题型有： 4. Reading Comprehension (Reading in Depth)Part IV Reading Comprehension (Reading in Depth) (25 minutes)Section ADirections: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.Over a century ago, Alfred Russell Wallace wrote that “we live in a zoologically poor world, from which all the hugest, fiercest and strangest forms have recently disappeared. “Researchers seeking to explain this “marvelous fact”, as Wallace called it, fall into two camps, one invoking global climatic change and the other human hunting as the cause. Over the past few decades, the debate has become deadlocked, in part because most researchers have focused their attention on the Americas and northern Eurasia, where the extinction of the huge, fierce, and strange creatures, such as mammoths, and giant sloths(大树懒), occurred between 12, 500 and about 11, 000 years ago. This was a time of rapid climatic change, but it was also when humans first arrived in these regions, making it difficult to discern causality. Australia provides the only separate, continent-sized natural laboratory in which dramatic Quaternary extinctions occurred. It is thus of exceptional importance as a testing ground for extinction theories, but until now problems with dating have limited its potential. Miller and some people have now documented the extinction of the gigantic Australian bird and so have broken new ground in dating huge creatures extinction in Australia. At the same time, these authors have broken the current deadlock in the great huge creature extinction debate. It has long been appreciated that the intensity of Quaternary extinctions varied greatly around the world. In the oceans, Africa, and Southeast Asia, they were nonexistent or mild. Europe experienced moderate extinction rates, whereas the Americas, Australia, Madagascar, and many Oceanic islands suffered dramatic extinctions. North America lost 73% of all forms weighing more than 44 kg, but Australia suffered the most severely of all the continents, losing every terrestrial vertebrate(脊椎动物)species larger than a human, as well as many smaller mammals, reptiles, and flightless birds, the latter down to about a kilogram in weight. In all, about 60 vertebrate species were lost, including bizarre marsupials(有袋类动物)that resembled giant sloths, kangaroos, and a terrestrial horned tortoise that approached the size of a V olkswagen Beetle car. Establishing just when this bizarre array of creatures last trod Australia’s outback has been an intricate business, with many false leads and sites that are difficult to interpret. For decades, it was believed that the huge creatures survived until close to the time of the glacial maximum, some 20, 000 years ago, when temperatures were up to 9t cooler than at present and the continent was extremely arid. Conditions were so extreme that trees virtually disappeared from the inland, and 40% of Australia wastransformed into a vast active dune field.1．Alfred Russell Wallace thought our world is zoologically poor because of______.正确答案：the disappearing of the hugest, fiercest and strangest forms解析：根据线索词zoologically poor定位在第一段第一句话上，文中说我们生活在一个物种数量减少的时代，所有那些最大、最凶猛、最奇怪的物种近来都从世界上消失了…，本题将原文中的from which…非限制性定语从句转化成一个原因状语，需用disappear的动名词形式。

大学英语六级（阅读）模拟试卷19(题后含答案及解析) 题型有： 4. Reading Comprehension (Reading in Depth)Part IV Reading Comprehension (Reading in Depth) (25 minutes)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.Traffic statistics paint a gloomy picture. To help solve their traffic woes(苦恼), some rapidly growing U. S. cities have simply built more roads. But traffic experts say building more roads is a quick-fix solution that will not alleviate the traffic problem in the long run. Soaring land costs, increasing concern over social and environmental disruptions caused by road-building, and the likelihood that more roads can only lead to more cars and traffic are powerful factors bearing down on a 1950s-style constructions program. The goal of smart-highway technology is to make traffic systems work at optimum efficiency(最佳效率)by treating the road and the vehicles traveling on them as an integral transportation system. Proponents of this advanced technology say electronic detection systems, closed-circuit television radio communication, ramp(斜坡)metering, variable message signing, and other smart-highway technology can now be used at a reasonable cost to improve communication between drivers and the people who monitor traffic. Pathfinder, a Santa Monica, California-based smart-highway project in which a 14-mile stretch of the Santa Monica Freeway makes up what is called a “smart corridor”, is being instrumented with buried loops in the pavement. Closed-circuit television cameras survey the flow of traffic, while communications linked to properly equipped automobiles advise motorists of the least congested routes or detours(便道). Not all traffic experts, however, look to smart-highway technology as the ultimate solution to serious traffic jam. Some say the high-tech approach is limited and can only offer temporary solutions to a serious problem. “Electronics on the highway addresses just one aspect of the problem: how to regulate traffic more efficiently,”explains Michael Renner, senior researcher at the World-watch Institute. “It doesn’t deal with the central problem of too many cars for roads that can’t be built fast enough. It sends people the wrong message. They start thinking ‘Yes, there used to be a traffic congestion problem, but that’s been solved now because we have an advanced high-tech system in place. ‘“ Barson agrees and adds, “Smart highways is just one of the tools that we will use to deal with our traffic problems. It’s not the solution itself, just part of the package. There are different strategies. “Other traffic problem-solving options being studied and experimented with include car pooling, rapid mass transit systems, staggered or flexible work hours, and road pricing, a system whereby motorists pay a certain amount for the time they use a highway. It seems that we need a new, major thrust to deal with the traffic problems of the next20 years. There has to be a big change.1．What is the appropriate title for the passage?A．Smart Highway Projects —The Ultimate Solution to Traffic CongestionB．A Quick Fix Solution to the Traffic ProblemsC．A Venture to Remedy Traffic WoesD．Highways Get Smart —Part of the Package to Relieve Traffic Gridlock正确答案：D解析：主旨大意题。
英语六级考试阅读理解模拟题及答案（2）
英语六级考试阅读理解模拟题及答案（2）文章精要文章指出，目前美国大学在录取新生时，仍然比较看重分数。
在一些学校里由于奖学金政策的执行，学生的分数迅速攀升。
考试的拥护者指出，考试有必要存在，因为它给学生提供了展示自我的平台，而这也无疑会给学生带来巨大的压力。
答案解析1. E 本题的出题点在E段的最后一句话，属于数字题。
从原文可以看出，申请者的人数为47,317，而获得4.0或者4.0以上分数者的人数接近23,000，由此可知比例接近50%。
2. F 本题是F段的总结。
原文提到，对学生的选拔最为严格的学校也越来越难以参与到降低标准考试的影响的活动中来，也就是说，这些学校很难降低标准考试的影响。
3. K 本题的出题点在K段的最后两句话，属于数字题。
More than 30 years ago可推测应该是上世纪七八十年代，对应原文的1975年;从原文可以看出，在大一新生中，2005年在高中取得A或者更好成绩的人数差不多是总人数的!%%，而在1975年时此比例减半，大约为11.5%。
4. H 本题的出题点在H段。
原文提到最近标准考试有一些负面影响，许多学校已经停止要求用考试分数来评判学生。
题干的negative effects转述了原文的bad publicity。
5. D 本题是对D段前两句话的同义转述。
原文提到：有些人把Zalasky的努力这种现象称为“分数膨胀”，暗示他的这种进步不值得接受，而其他人认为那些学生真正赢得了好的评价，题干中的win the praise for him同义转述了原文中的earning their better marks。
6. B 本题的出题点在B段的第一句和第五句。
原文提到even Zalasky is nervous about his prospects。
接着在第五句中提到了原因：It’s that so many of his classmates are so good.由此可知题目是这两句的总结。

国内的各类英语考试中几乎都有阅读理解题型，大学英语六级考试也不例外。
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。
