大学英语六级真题试卷-(13)精选全文完整版
可编辑修改精选全文完整版大学英语六级真题试卷Questions 31 to 35 are based on the following passage.We all have offensive breath at one time or another. In most cases, offensive breath emanates from bacteria in the mouth, although there are other more causes.Until a few years ago, the most doctors could do was to counsel patients with bad breath about oral cleanliness. Now they are finding new ways to treat the usually curable condition.Bad breath can happen whenever the normal flow of saliva (唾液) slows. Our mouths are full of bacteria feeding on protein in bits of food and shed tissue. The bacteria emit evil smelling gases, the worst of which is hydrogen sulfide (硫化物).Mouth bacteria thrive in airless conditions. Oxygen rich saliva keeps their numbers down. When we sleep, for example, the saliva stream slows, and sulfur producing bacteria gain the upper hand, producing classic “morning breath”.Alcohol hunger, too much talking, breathing through the mouth during exercise anything that dries the mouth produces bad breath. So can stress, though it’s not understood why. Some people’s breath turns sour every time they go on a job interview.Saliva flow gradually slows with age, which explains why the elderly have more bad breath trouble than younger people do. Babies, however, who make plenty of saliva and whose mouths contain relatively few bacteria have characteristically sweet breath.For most of us, the simple, dry mouth variety of bad breath is easily cured. Eating or drinking starts saliva and sweeps away many of the bacteria. Breakfast often stops morning breath.Those with chronic dry mouth find that it helps to keep gum, hard candy, or a bottle of water or juice around. Brushing the teeth wipes out dry mouth bad breath because it clears away many of the offending bacteria.Surprisingly, one thing that rarely works is mouthwash. The liquid can mask bad breath odor with its own smell, but the effect lasts no more than an hour. Some mouthwashes claim to kill the bacteria responsible for bad breath. The trouble is, they don’t necessarily reach all offending germs. Most bacteria are well protected from mouthwash under thick layers of mucus (粘液). If the mouthwash contains alcohol-as most do-it can intensify the problem by drying out the mouth.31. The phrase “emanate from”in Paragraph 1 most probably means “________”.A) thrive onB) account forC) originate fromD) descend from32. Which of the following is mentioned as one of the causes of bad breath?A) Tooth trouble.B) Sulfur rich food.C) Too much exercise.D) Mental strain.33. According to the passage, alcohol has something to do with bad breath mainly because ________.A) it keeps offending bacteria from reproducingB) its smell adds to bad breathC) it kills some helpful bacteriaD) it affects the normal flow of saliva34. Mouthwashes are not an effective cure for bad breath mainly because ________.A) they can’t mask the bad odor long enoughB) they can’t get to all the offending bacteriaC) their strong smell mixes with bad breath and makes it worseD) they can’t cover the thick layers of mucus35. We can infer from this passage that ________.A) offensive breath can’t easily be curedB) elderly people are less offended by bad breathC) heavy drinkers are less affected by bad breathD) offensive breath is less affected by alcoholQuestions 36 to 40 are based on the following passage.“Welcome to the U.S.A.! Major Credit cards accepted!”By the millions they are coming no longer the tired, the poor, the wretched mass longing for a better living. These are the wealthy. “We don’t have a budget,”says a biologist from Brazil, as she walks with two companions through New York City’s South Street. “We just use our credit cards.”The U.S. has long been one of the world’s most popular tourist destinations, but this year has been exceptional. First there was the World Cup, which drew thousands from every corner of the globe; then came the weakening of the U.S. dollar against major currencies. Now the U.S., still the world’s superpower, can also claim to be the world’s bargain basement (廉价商品部). Nobody undersells America these days on just about everything, from consumer electronics to fashion clothes to tennis rackets. Bottom retail prices-anywhere from 30% to 70% lower than those in Europe and Asia-have attracted some 47 million visitors, who are expected to leave behind $79 billion in 1994. That’s up from $74 billion the year before.True, not everyone comes just for brains. There remains an undeniable fascination in the rest of the world with all things American, nourished by Hollywood films and U.S. television series. But shopping the U.S.A. is proving irresistible. Every week thousands arrive with empty suitcases ready to be filled; some even rent an additional hotel room to hold their purchases. The buying binge (无节制) has become as important as watching Old Faithful Fountains erupt in Yellowstone Park or sunbathing on a beach in Florida.The U.S. has come at last to appreciate what other countries learned long ago: the pouring in of foreign tourists may not always be convenient, but is does put money in the bank. And with a trade deficit at about $130 billion and growing for the past 12 months, the U.S. needs all the deposits it can get. Compared with American tourists abroad, visitors to the U.S. stay longer and spend more money at each stop; an average of 12.2 night and $1624 a traveller versus the American s’four nights and $298.36. From what the Brazilian biologist says, we know that tourists like her ________.A) are reluctant to carry cash with themB) simply don’t care how much they spendC) are not good at planning their expenditureD) often spend more money than they can afford37. The reason why 1994 was exceptional is that ________.A) it saw an unusually large number of tourists to the U.S.B) it witnessed a drop in the number of tourists to the U.S.C) tourism was hardly affected by the weakening of the U.S. dollar that yearD) tourists came to the U.S. for sightseeing rather than for bargains that year38. By saying “nobody undersells America”(Line 4, Para. 3), the author means that ________.A) no other country underestimates the competitiveness of American productsB) nobody expects the Americans to cut the prices of their commoditiesC) nobody restrains the selling of American goodsD) no other country sells at a lower price that America39. Why does the author assert that all things American are fascinating to foreigners?A) Because they have gained much publicity through the American media.B) Because they represent the world’s latest fashions.C) Because they embody the most sophisticated technology.D) Because they are available at all tourist destinations.40. From the passage we can conclude that the U.S. has come to realize ________.A) the weakening if the U.S. dollar can result in trade deficitsB) the lower the retail prices, the greater the profitsC) tourism can make great contributions to its economyD) visitors to the U.S. are wealthier than U.S. tourists abroadPart III Vocabulary (20 minutes)Directions: There are 30 incomplete sentences in this part.

Reading ComprehensionAdvertising follows us everywhere. Whenever we turn on the television, listen to the radio or open a newspaper or a magazine, we are bombarded, with advertisements. They invite us to try a new type of orange juice, wear X-brand jeans or watch the latest film. They beg us to notice the difference and discover the advantages. They exist to make us want what they are selling. Strangely, the more we are exposed to advertising, the less we notice it. We get so used to seeing advertisements everywhere that they become largely invisible, as if they were another part of our everyday lives. But does that mean that we are no longer affected by them? One advertising expert believes that the special power of advertisinglies in the fact that we do not pay much attention to it. Dr. Krugman, who was head of research for a major **pany for many years, says that the less we notice ads, the more we are affected by them. Dr. Krugman believes that when we stop noticing advertisements, we lower our defenses, allowing the messages of the advertisements to be taken in and stored, ready to be triggered into action at the right moment. He says that the effects of advertising on the individual are small, but over a period of time they have a powerful effect on the masses. A market analyst says that all advertising, no matter how innocent, is misleading in some way. When asked about the power of advertising in research surveys, most people agree that it works, but not on them. Almost everyone believes that they **plete control over how thousands of ads they see every day affect them.SSS_SINGLE_SEL1.Ads exist to make people want ( ).A a new type of orange juiceB X-brand jeansC to watch the latest filmD what they advertise该题您未回答:х该问题分值: 2答案:DSSS_SINGLE_SEL2.The more we see ads, the less we ( ).A pay attention to themB feel tired of themC neglect themD put up with them该题您未回答:х该问题分值: 2答案:ASSS_SINGLE_SEL3.Although we may think we are not Affected by them, Dr. Krugman believes that advertisements affect ( ).A all of usB most of usC some of usD a few individuals该题您未回答:х该问题分值: 2SSS_SINGLE_SEL4.Dr. Krugman believes that when we stop noticing ads, we begin to ( ).A like themB be on guard against themC accept themD dislike them该题您未回答:х该问题分值: 2答案:CSSS_SINGLE_SEL5.When asked about the power of ads, most people agree that ads are ineffective on ( ).A individualsB massesC othersD them该题您未回答:х该问题分值: 2答案:DLike most people, I was brought up to look upon life as a process of getting. It was not until in my late thirties that I made this important discovery: giving away makes life so much more exciting. You need not worry if you lack money. This is how I experimented with giving away. If an idea for improving the window display of a neighborhood store flashes to me, I step in and make the suggestion to the storekeeper. One discovery I made about giving away is that it is almost impossible to give away anything in this world without getting something back, though the return **es in an unexpected form. One Sunday morning the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation." Wasn't it you that wrote us that letter a year ago about delivering a special delivery to your home?" I said yes. "Well, you certainly are going to have a box in this post office if we have to make one for you. You don't know what a letter like that means to us. We usually get nothing **plaints."SSS_SINGLE_SELFrom the passage, we understand that ( ).A the author did not understand the importance of giving until he was in late thirtiesB the author was like most people who were mostly receivers rather than giversC the author received the same education as most people during his childhoodD the author liked most people as they looked upon life as a process of getting该题您未回答:х该问题分值: 2答案:ASSS_SINGLE_SEL7.According to the author ( ).A giving means you will lack moneyB the excitement of giving can bring you moneyC you don't have to be rich in order to giveD when you give away money, you will be rich该题您未回答:х该问题分值: 2答案:CSSS_SINGLE_SEL8.The author wrote a note of appreciation to the post office because ( ).A he knew what such a note would mean to the post officeB he had discovered giving-away made life more excitingC he believed he would get something back by doing soD the postman delivered an important letter in time该题您未回答:х该问题分值: 2答案:DSSS_SINGLE_SEL9.When the author needed a post office box, ( ).A he had to put his name on a waiting listB he wrote the postmaster a note of appreciationC many people had applied for post-office boxes before himD he asked the postmaster to make one for him该题您未回答:х该问题分值: 2SSS_SINGLE_SEL10.In reply to the postmaster's question, the author said ( ).A it was the special deliveryB it was the post-office boxC it was the note of appreciation he wroteD it was he who wrote him a letter a year ago该题您未回答:х该问题分值: 2答案:DGenerations of Americans have been brought up to believe that a good breakfast is one of life's essentials. Eating breakfast at the start of the day, we have all been told, is as necessary as putting gasoline in the family car before starting a trip. But for many people the thought of food first thing in the morning is by no means a pleasure. So despite all the efforts, they still take no breakfast. Between 1977 and 1983, the latest years for which figures are available, the number of people who didn't have breakfast increased by 33 percent—from 8.8 million to 11.7 million—according to the Chicago-based Market Research Corporation of America. For those who feel pain or guilt about not eating breakfast, however, there is some good news. Several studies in the last few years indicate that, for adults especially, there may be nothing wrong with omitting breakfast. "Going without breakfast does not affect performance." said Arnold E. Bender, the former professor of nutrition at Queen Elizabeth College in London, " nor does giving people breakfast improve performance." Scientific evidence linking breakfast to better health or better performance is surprisingly inadequate, and most of the recent work involves children, not adults. "The literature, "says one researcher, Dr. Ernesto Pollitt at the University of Texas, "is poor".SSS_SINGLE_SEL11.The passage is mainly concerned with ( ).A a study of the Chicago-based Market Research CorporationB one of life's essentialsC latest figures of people who don't eat breakfastD breakfast and human health该题您未回答:х该问题分值: 2答案:DSSS_SINGLE_SEL12.For those who do not take breakfast, the good news is that ( ) .A several studies have been done in the past few yearsB not eating breakfast does no harm to one's healthC adults have especially made studies in this fieldD eating little in the morning may be good for health该题您未回答:х该问题分值: 2答案:BSSS_SINGLE_SEL13.In the third paragraph, "nor does giving people breakfast improve performance." means ( ) .A anyone without breakfast does improve his performanceB not giving people breakfast improves performanceC people having breakfast do improve their performanceD having breakfast does not improve performance, either该题您未回答:х该问题分值: 2答案:DSSS_SINGLE_SEL14.The word "literature" in the last sentence refers to ( ).A stories about breakfastB written works on a particular subjectC any printed materialsD the modern novels of American该题您未回答:х该问题分值: 2答案:ASSS_SINGLE_SEL15.What is implied but not stated by the author is that ( ).A not eating breakfast might affect the health of childrenB breakfast does not affect performanceC Professor Bender once taught college courses in nutrition in LondonD People who don't eat breakfast have increased该题您未回答:х该问题分值: 2答案:AEach day, computers help millions of people do their jobs more effectively. For example, they can help managers decide on a future course of action, and they can then help with the follow-up checks onperformance to see if planned goals are being achieved. By using accurate and timely facts supplied by data base management software,a manager can do a better job of identifying problems and opportunities. And managers may not need to spend as much time in controlling when a computer can respond with a triggered report if actual performance varies from what was planned. The time saved in controlling may allow managers to give more attention to employees' concerns, and this, in turn, may result in improved morale (土气) . But employment benefits certainly aren't restricted to managers. Healthcare researchers and other scientists also **puters to conduct research **plex problem areas that couldn't otherwise be studied. Lawyers use online legal data banks to locate precedent (先前的)cases in order to serve clients better. Salespeople can receive more timely information about products in stock, can promise customersthat their sales orders will be handled promptly, and can thus improve their sales performance because of **puter system. And thejob duties of some office and factory workers have changed from routine, repetitive operations to more varied and appealing tasks**puter usage. For example, office workers who understand text processing, computing, and **munication usually have vital roles and are given critical office functions to perform.SSS_SINGLE_SEL16.Which of the following examples shows the controlling function of a computer?A Helping managers decide on a future course of actionB Helping managers check if planned goals are reachedC Helping managers save time in writing a reportD Helping managers design a spreadsheet package该题您未回答:х该问题分值: 2答案:BSSS_SINGLE_SEL17.Employees may have better morale if ( ).A they have more time to restB a computer is used in their workC the manager spends more time with themD the managers pay more attention to them该题您未回答:х该问题分值: 2答案:DSSS_SINGLE_SEL18.Which of the following is the most essential to a successful businessman?A He can **puters in his work.B He can handle orders promptly.C He can get timely information.D He can improve his sales performance该题您未回答:х该问题分值: 2答案:CSSS_SINGLE_SEL19.The office duties used to be ( ).A difficultB boringC heavyD appealing该题您未回答:х该问题分值: 2答案:BSSS_SINGLE_SEL20.Which of the following is the best suggested title?A Computers and ManagementB Computer FunctionsC Computer and Work PerformanceD Employment Benefits by a Computer该题您未回答:х该问题分值: 2答案:D3.
