Less than atenth of the people are engaged in agriculture and forestry (林业) , and most of the rest live in oraround towns, small and large. Here the traditional picture is changing: every small town may stillbe very like other small towns, and the typical small town may represent a widely accepted viewof the country, but most Americans do not live in small towns any more. Half the population nowlives in some thirty metropolitan areas (large cities with their suburbs) of more than a millionpeople each ---- a larger proportion than in Germany or England, let alone France. The statistics(统计) of urban and rural population should be treated with caution because so many people wholive in areas classified as rural travel by car to work in a nearby town each day. As the rush to liveout of town continues, rural areas within reach of towns are gradually filled with houses, so that itis hard to say at what moment a piece of country becomes a suburb. But most and more the typicalAmerican lives in a metropolitan rather than a small town environment.1). If now America has 250 million people, how many of them are engaged in agriculture andforestry?A. About 25 million.B. More than 25 million.C. Less than 25 million.D. Less than 225 million.正确答案：C。

）1. New technology links the world as never before. Our planet has shrunk. It’s now a “global village” where countries are only seconds away by fax or phone or satellite link. And. of course, our ability to benefit from this high-tech communications equipment is greatly enhanced by foreign language skills.Deeply involved with this new technology is a breed of modern businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support domestic business efforts.Overseas assignments are becoming increasingly important to advancement within executive ranks. The精品executive stationed in another country no longer need fear being精品“out of sight and out of mind.” He or she can be sure that the overseas effort is central to the company’s plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to cope back in the United States where cross-cultural considerations and foreign language issues are becoming more and more prevalent (普遍的).Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets.精品English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn’t generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equalThe employee posted abroad who speaks the country’s principal language has an opportunity to fast-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign clients over the telephone or by fax machine is an obvious asset to the firm.1).What is the author’s attitude toward high-tech communications equipment精品A. Critical.B. Indifferent.C. Prejudiced.D. Positive.满分：2分2).With the increased use of high-tech communications equipment, businesspeople ______.A. have to get familiar with modern technologyB. are gaining more economic benefits from domestic operationsC. are attaching more importance to their overseas businessD. are eager to work overseas满分：2分3).In this passage, “out of sight and out of mind” (Lines 2-3, Para. 3) probably means ____.精品A. being unable to think properly for lack of insightB. being totally out of touch with business at homeC. missing opportunities for promotion when abroadD. leaving all care and worry behind满分：2分4).According to the passage, what is an important consideration of international corporations in employing people todayA. Connections with businesses overseas.B. Ability to speak the client’s language.C. Technical know-how.D. Business experience.满分：2分5).The advantage of employees having foreign language skills is that they can _______.A. better control the whole negotiation process精品B. easily find new approaches to meet market needsC. fast-forward their proposals to headquartersD. easily make friends with businesspeople abroad满分：2分2.Like most people, I was brought up to look upon life asa 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 often comes in an unexpected form. One Sunday morning the local post office delivered an important精品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 (无意中听到) our conversation.精品“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 but complaints.”精品1).From 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满分：2分2).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 give精品D. when you give away money, you will be rich满分：2分3).The author would make the suggestion to the storekeeper___________ .A. in writingB. in personC. in the window displayD. about the neighborhood满分：2分4).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 him精品D. he asked the postmaster to make one for him满分：2分5).In reply to the postmaster's question, the author said _________ .A. it was the special deliveryB. C. D.B. 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满分：2分3.Ask Steveland Morris and he’ll tell you that blindness is not necessarily disabling(残疾的). Steveland was born prematurely(早产) and totally without sight in 1950. He became Steve Wonder --- composer, singer, and pianist. The精品winner of ten Grammy Awards(格莱美奖), Steve is widely acclaimed for his outstanding contributions to the music world.精品As a child, Steve learned not to think about the things he could not do, but to concentrate on the things that he could do. His parents encouraged him to join his sighted brothers in as many activities as possible. They also helped him to sharpen his sense of hearing, the sense upon which the visually disabled are so dependent.Because sound was so important to him, Steve began at an early age to experiment with different kinds of sound. He would bang things together and then imitate(模仿) the sound with his voice. Often relying on sound for entertainment, he sang, beat on toy drums(鼓), played a toy harmonica(口琴), and listened to the radio.精品Steve soon graduated from toy instruments to real instruments. He first learned to play the drums. He then mastered the harmonica and the piano. He became a member of the junior church choir and a lead singer. In the evenings and on weekends, Steve would play different instruments and sing popular rhythm and blues (布鲁斯音乐)tunes on the front porches of neighbors’ homes. One of Steve’s sessions was overheard by Ronnie white, a member of a popular singing group called The Miracles. Ronnie immediately recognized Steve’s talent(才华) and took him to audition (试演) for Berry Gordy, the president of Hitsville USA, a large recording company now known as Motown. Steve recorded his first smash hit(极为轰动的)精品“fingertips” in 1962 at age twelve, and the rest of Steve’s story is music history.1).This passage can be entitled (取名为)______ .A. The Music WorldB. Steve WonderC. Great MusiciansD. Blind People满分：2分2).By saying “Steve soon graduated from toy instruments to real instruments”, the author means that ______ .A. Steve finished his study at a toy instrument school.B. Steve began to study in a real instrument school.C. Steve gave up all his toy instruments and began to buy many real instruments.精品D. Steve started to play real instruments.满分：2分3).Which of the following statements is NOT true about Steve’s childhoodA. Steve often tells people that a blind person is not necessarily disabled.B. He learned to concentrate on things that he could do.C. He played as often as possible with his brothers, who had normal sight.D. He tried very hard to train his sense of hearing.满分：2分4).The author mentions all the following facts EXCEPT that ______ .A. Steve’s neighbors could often enjoy his playing and singing.精品B. It was Ronnie White that recognized Steve’s talent and led him to a successful career.C. Berry Gordy helped him set up his own recording company.D. Steve’s parents played a very important role in training his sense of hearing.满分：2分5).The “Fingertips” ________ .A. recorded Steve’s musical performance that won him instant fameB. was a record that turned out to be a great successC. carried the message that the blind could work miracles with their fingertipsD. all of the above满分：2分精品4. People living on parts of the south coast of England face a serious problem. In 1993, the owners of a large hotel and of several houses discovered, to their horror, that their gardens had disappeared overnight. The sea had eaten into the soft limestone cliffs on which they had been built. While experts were studying the problem, the hotel and several houses disappeared altogether, sliding down the cliff and into the sea.Erosion（侵蚀）of the white cliffs along the south coast of England has always been a problem but it has become more serious in recent years. Dozens of homes have had to be abandoned as the sea has crept farther and farther inland. Experts have studied the areas most affected and have drawn up a map for local people, forecasting the year in which their homes will be swallowed up by the hungry sea.精品Angry owners have called on the Government to erect sea defenses to protect their homes. Government surveyors have pointed out that in most cases, this is impossible. New sea walls would cost hundreds of millions of pounds and would merely make the waves and currents go further along the coast, shifting the problem from one area to another. The danger is likely to continue, they say, until the waves reach an inland area of hard rock which will not be eaten as limestone is. Meanwhile, if you want to buy a cheap house with an uncertain future, apply to a house agent in one of the threatened areas on the south coast of England. You can get a house for a knockdown price but it may turn out to be a knockdown home.1).What is the cause of the problem that people living on parts of the south coast of England face精品A. The rising of the sea level.B. The experts’ lack of knowledge.C. The washing-away of limestone cliffsD. The disappearance of hotels, houses and gardens.满分：2分2).The erosion of the white cliffs in the south of England __________.A. will soon become a problem for people living in central EnglandB. has now become a threat to the local residentsC. can be stopped if proper measures are takenD. is quickly changing the map of England满分：2分3).The experts’study on the problem of erosion to __________.精品A. warn people whose homes are in dangerB. provide an effective way to slow it downC. head to its eventual solutionD. lead to its eventual solution满分：2分4).It is not feasible to build sea defenses to protect against erosion because __________.A. house agents along the coast do not support the ideaB. it is too costly and will endanger neighbouring areasC. the government is too slow in taking actionD. they will be easily knocked down by waves and currents 满分：2分5).According to the author, when buying a house along the south coast of England, people should _________.精品A. take the quality of the house into considerationB. guard against being cheated by the house agentC. examine the house carefully before making a decisionD. be aware of the potential danger involved满分：2分二、单选题（共15道试题，共45分。

）1. Our child’s behavior is greatly influenced by the way we react to what he has done. Our reactions help to determine whether our child will repeat his behavior or whether he will do something different. This statement is a very important part of a principle of behavioral psychology.The principle states that a behavior is influenced or affected by how the environment---people, places and things---immediately responds to the behavior. Perhaps without realizing it, you have used this principle many times. On the occasion when you told your child what a good boy he was after he cleaned up his room, you used the principle. When you sent your child to his room for fighting with his brother, you used the principle. In these examples, a particular behavior occurred first---cleaning up a room and fighting.In addition, there was a reaction to each behavior---the childwas praised, sent to his room. By these actions, we have influenced the previous behaviors and have helped to determine whether those behaviors will occur again in the future.1). What is the passage mainly about?A. Children and environment.B. Children’s behavior and fighting.C. Children’s behavior and people’s response.D. Children and principles.正确答案：C2). On what kind of principle is this passage based?A. A principle in chemistry.B. A principle in behavioral psychology.C. A principle in physics.D. A principle in social psychology.正确答案：B3). Who do you think the readers of the passage might be?A. Teachers.B. Doctors.C. Students.D. Parents.正确答案：D4). According to the passage, why was the child sent to his room?A. As a kind of punishment.B. As a kind of reward.C. As an experiment on the principle.D. As an example of the principle.正确答案：A5). What does the writer mean by “environment”?A. Rooms.B. Water and air.C. People, places and things.D. Family and friends.正确答案：C2.At the European Commission in Brussels, they have a joke aboutthe work interpreters do –“languages”, they say, “have nothing to do with interpretation,” which helps to know them. Anyone thinking of becoming an interpreter would bear this so well in mind. Translating languages, especially in a political context, involves far more than mere linguistic ability.To work in an international organization, such as the United Nations, you need to be approved by one of the various international translators’ or interpreters’ associations. To achieve this, you must experience rigorous and lengthy training, either at an authorized organization’s own school, or on a postgraduate course at university. But a qualification in languages is not the only route into the job. At London’s University of Westminster, candidates get offered a place on the interpreter’s course if they can show that they have “lived a bit”, in the words of one lecture. Young people who have just left university often lack adequate experience of life.The university also looks for candidates who have lived for long time in the countries where their acquired languages arespoken. They are also expected to have wide cultural interests and a good knowledge of current affairs. This broad range of interests are essential in a job which can require interpreting discussions of disarmament (裁军) on Monday, international fishing rights on Tuesday, multinational finance on Wednesday, and the building and construction industry on Thursday. Interpreters also rely on adrenaline (肾上腺素) —which is caused by the stress and challenges of the job — to keep them going through their demanding schedules. Many admit that they enjoy the buzz of adrenaline they get from the job, and it’s known that their heart rates speed up while they are working. It’s also a job with its own risks and excitement. Interpreters are needed in war zones as well as in centers of international diplomacy, like the UN.1). What does “have lived a bit” mean?A. To be older than others.B. To travel to more countries.C. To have abundant life experience.D. To have longer training in interpreting.正确答案：C2). Candidates for the training course in London’s University of Westminster need the following qualifications EXCEPT ______.A. having wide cultural interestsB. having a good knowledge of current affairsC. being familiar with the languages they translateD. being eloquent lectures正确答案：D3). The interpreters rely on adrenaline because ______.A. it can help finish their work quicklyB. it can make them excitedC. it can prevent them from heart diseaseD. it can make them work harder正确答案：B4). According to the passage, we can infer that ______.A. language has nothing to do with interpretingB. only those postgraduates from the foreign languageuniversities can work as interpretersC. interpreters must live in the country where the required language is spokenD. interpreters build the bridge for international communication 正确答案：D5). The job as interpreter has the following characteristics EXCEPT ______.A. funnyB. daringC. dangerous sometimesD. exciting正确答案：A3.Almost every family buys as least one copy of a newspaper every day. Some people subscribe to as many as two or three different newspapers. But why do people read newspapers?Five hundred years ago, news of important happenings--battles lost and won, kings or rulers overthrown(推翻) or killed took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important events that occur in far away countries on the same day they happen.Apart from supplying news from all over the world, newspapers give us a lot of other useful information. There are weather reports, radio, television and film guides, book reviews, stories, and of course, advertisements. The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for the advertising space, but it is worth the money for news of their products goes into almost every home in the country. For those who produce newspapers, advertisements are also very important. Money earned from advertisements makes it possible for them to sell their newspapers at a low price and still make a profit.1). The phrase "subscribe to" in the first paragraph means" _________".A. go to the newspaper stand and buyB. send their own news stories toC. agree to buy for a specific period of timeD. become faithful readers of正确答案：C2). The habit of reading newspapers is _________ .A. widespreadB. found among a few familiesC. not popularD. uncommon正确答案：A3). Before the time of the newspaper, __________ .A. bad news traveled quickly and good news slowlyB. few people cared about events that took place in far away countriesC. kings and rulers were often overthrown or killedD. news was passed from one person to another正确答案：D4). The author seems to agree that money spent on advertisements is _________ .A. wastedB. not muchC. well spentD. of no use to anyone正确答案：C5). which of the following statements is TRUE?A. Five hundred years ago it took a long time for news to reach other countries.B. Newspaper advertisements turn people's attention away from their productsC. The news that we read in newspapers is mainly about new products.D. When newspapers are sold at a low price, the newspaper producers will lose money.正确答案：A4. When Mrs. Joseph Groeger died recently in Vienna, Austria, people asked the obvious, “Why did she live to be 107?” Answers were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100. Somewhat surprising was the fact that the majority had lived most of their lives in cities. In spite of the city’s image as an unhealthy place, city living often provides benefits that county living can lack. One factor seems to be important to the longevity (长寿) of those interviewed.This factor is exercise. In the cities it is often faster to walk short distances than to wait for a bus. Even taking publictransportation often requires some walking. Smaller apartment houses have no elevators (电梯), and so people must climb stairs. City people can usually walk to local supermarkets. Since parking spaces are hard to find, there is often no alternative to walking.On the other hand, those who live in the country and suburbs do not have to walk every day. In fact, the opposite is often true. To go to school, work, or almost anywhere else, they must ride in cars.1). The Vienna survey may help to explain _______.A. the complaints of people in apartment housesB. the cause of Mrs. Groeger’s deathC. the longevity of people like Mrs. GroegerD. the image of cities in general正确答案：C2). The purpose of the second paragraph is to list some _______.A. benefits of walkingB. occasions for walking in city lifeC. comments made by city peopleD. problems of city living正确答案：B3). To reach the third floor of a building, it would probably be most healthful ____.A. to take the elevatorB. to walk up the stairsC. to ride in a carD. to find an alternative to walking正确答案：B4). People who live in the country probably do more driving than walking because _______.A. they don’t live near business areasB. they don’t need the exerciseC. they never have parking problemsD. they can’t afford to take the bus正确答案：A5). A conclusion that can be drawn from this passage is that _______.A. air pollution is not seriousB. anyone can live to be 107C. country people should move to the cityD. walking is a healthful exercise正确答案：D15春学期《大学英语(三)》在线作业1阅读理解完型填空二、单选题（共15 道试题，共45 分。

Its first use was as a shade (遮光物)against the sun! Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the 11 century BC.We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And therewas a strange thing connected with its use: it became asymbol of honour and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those inhigh office.In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrellawas in common use in ancient Greece. But it is believed that thefirst persons in Europe to use the umbrella as protection against the rain were the ancient Romans.During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late 16th century. And again it was considered a symbol of power and authority. By 1680, the umbrella appeared in France, and later on in England.By the 18th century, the umbrella was used against rain throughout most of Europe. Umbrella have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the 20th century that women's umbrellas began to be made, in a whole variety of colours.6.According to this passage, the umbrella was probably firstinvented ______ .答案:in ancient China7.Which of the following statements is not true about the umbrella?答案:The umbrella changed much in style in the 18th century.8.A strange feature of the umbrella's use is that it was used as________ .答案:a symbol of honour and power9.In Europe, the umbrella was first used against the rain ______.答案:in Rome10.This passage talks mainly about______ .答案:the history and use of the umbrellaPassage 2In the United States, 30 percent of the grown-up population has a" weight problem". To manypeople, the cause is clear: we eat too much. But scientific experiments do little to support this idea. Going back to the America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines muchless, and didn't watch television.Several modern studies, besides, have shown that fatter people donot eat more on average than thinner people. In fact, some research work, such as the 1979 study of 3,545 London office workers, reports that fat people eat less than thinner people on average. Studies show that thin people are more active than fat people.A study by the research group at Standford University School of Medicine found the following fact: the more the man ran, the greater body fat he lost.The more he ran, the greater was his need for food. Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.11.What kind of physical problem do many grown-up Americans have?答案:They are too fat.12.Based on the information given in this article, suppose there are 500 grown-up Americans,about how many of them have a weight problem?答案:15013.Are there scientific facts to support that eating too much is the cause of the" weightproblem"?答案:There are hardly any scientific facts to support this./doc/828910399.html,pared with the grown-up Americans today, The Americans of1910_______.答案:ate more food and had more physical activities15.What have some modern medical and scientific researchers reported to us?答案:Fat people eat less food and are less active.第三部分:词汇与结构(共5小题;每小题3分，满分15分)16.The client may win in court, but at the_______of destroying the business relationship, hesays.答案:expense17.When I got home, the house was a complete _______.答案:mess18.We usually eat lunch at home, why don't we make a _______ to eat at the restaurant.答案:change19._______ you turn in your homework, you'd better check your answer carefully答案:Before20.When I take a train home, I usually read novels to _______the time.第四部分:完形填空(共10小题;每小题1分，满分10分)Most children with healthy appetites are ready to eat almost anything that is offered to them.

东大15秋学期《大学英语(三)》在线作业2满分答案阅读理解单选题完型填空一、阅读理解（共 4 道试题，共 40 分。

）1.Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employees and the self-employed. Labor is one of the country’s resources which can be combined with other resources to produce the goods and services required by the community.Though the size of the workforce relies on the size of the total population, there are several other aspects which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population has a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were an evenly spread age distribution. If the population grows rapidly from natural increase, i.e. the number of births greatly exceeds the number of deaths, then as a total population increases the proportion in the workforce declines.Sometimes a population is described as aging, which means the birth rate is either falling or growing very slowly, and as people retire from the workforce there are inadequate numbers of young people entering it to take the place of those who are leaving it. The population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate.The age distribution of population has several important influences on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonable level of social services for the retired group. If the aged are to be cared for in special homes or hotels, finance must be available for that purpose. If the size of the workforce is little relative to the total population, then the government tax receipts are relatively low and either the government has less money available to it or the workforce members have to be taxed more heavily.1). Labor force is composed of ______.大学英语视听说2答案A. people who are available to work and earn incomeB. self-employed people onlyC. only those who are looking for an employmentD. only the employees-----------------选择：A2). The factor which does NOT influence the size of the workforce is ______.A. the size of populationB. age distribution of the populationC. national economyD. natural increase-----------------选择：C3). The conclusion which can be drawn safely from the second paragraph is that ______.A. a population growth from natural increase leads to a greater proportion of the workforceB. a large population does not necessarily mean a higher proportion of workforceC. the larger the number of the aged in a population, the higher the proportion of the workforceD. if the population has an evenly spread age distribution, the work force will be lower-----------------选择：B4). When a population is said to be aging, ______.A. more people are retiring than people entering the workforceB. the birth rate is growingC. there is an oversupply of workforceD. young people outnumber old people-----------------选择：A5). The population which is top-heavy with older people poses a problem to ______.A. the governmentB. the economyC. the workforceD. all of the above-----------------选择：D2. April Fool’s Day is traditi onally a day to play practical jokes on others, send people on fool’s errands（差事）, and fool the unsuspecting. No one knows how this holiday began but it was thought to have originated in France. The closest point in time that can be identified as the beginning of this tradition was in 1582, in France. New Year was celebrated on March 25 and celebrations lasted until April 1st. When New Year’s Day as changed from March 25 to January 1st in the mid-1560’s by King Charles IX, there were some people who still celebrated it on April 1st and those people were called April Fools.Tricks performed on April Fool’s Day range from the simple to the elaborate. Setting a roommate’s alarm clock back an hour is common. The news media even gets involved. For instance, a Br itish short film once shown on April Fool’s Day was a fairly detailed documentary about “spaghetti farmers” and how they harvest their crop from the spaghetti trees. Whatever the prank, the trickster usually ends it by yelling to his victim, “April Fool!” April Fool’s Day is a “for-fun-only” observance. Nobody is expected to buy gifts or to take their “significant other” out to eat in a fancy restaurant. Nobody gets off work or school. It’s simply a fun little holiday, but a holiday on which one must remain forever vigilant（警惕的）, for he may be the next April Fool!Each country celebrates April Fool’s differently. In France, the April Fool’s is called “April Fish”. The French fool their friends by taping a paper fish to their friends’ backs. In England, tric ks can be played only in the morning. If a trickis played on you, you are a “noodle”.1). April Fool’s Day was first celebrated in_________.A. EnglandB. AmericaC. FranceD. Rome-----------------选择：C2).

It can be concluded that ______.A. those who are mentally slow are called April FoolsB. people have been celebrating April Fool’s Day for well over five centuriesC. the celebration of April Fool’s Day is more or less the same.D. the celebration of April F ool’s Day varies from country to country-----------------选择：D3. The resources of the library can be helpful even when we are doing something very informal, such as trying to devise a better way to measure attitudes toward music or looking for a better way to teach mathematics. The library can be equally helpful when we are doing something very formal, such as writing a dissertation (学位论文) or preparing an article for publication in a professional journal. In either case, our goal should be to use the library as a useful tool to help us understand and solve our problem.The following sections of this chapter will describe specific resources available in many libraries. In some cases you may already be aware of a resource and may use it frequently and successfully. In other cases you may be completely unfamiliar with a resource. Your goal should be to become aware of what is available and to know how to use each of these resources to help you solve the problem they are designed to solve.When educators have a piece of information that they want to share with their colleagues, they often make this information available in professional journals or at professional meetings. It would often be useful to have access to such information, and this chapter will describe the special services that enable us to locate such information.1). The library resources can be helpful when we _______.A. want to find a better way to measure attitudes toward musicB. are preparing a paper for a professional journalC. are writing a dissertationD. All of the above-----------------选择：D2).

When educators wish to share some information with their colleagues, they often _______.A. publish it in a professional journalB. attend professional meetingsC. get access to it in the libraryD. make use of some library services-----------------选择：A5). The chapter in question _______.A. mainly deals with the ways of dissertation writingB. presents information on publishing papers in professional journalsC. introduces some library servicesD. describes some professional meetings-----------------选择：C4. When Mrs. Joseph Groeger died recently in Vienna, Austria, people asked the obvious, “Why did she live to be 107?” Answers were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100. Somewhat surprising was the fact that the majority had lived most of their lives in cities. In spite of the city’s image as an unhealthy place, city living ofte n provides benefits that county living can lack. One factor seems to be important to the longevity (长寿) of those interviewed.This factor is exercise. In the cities it is often faster to walk short distancesthan to wait for a bus. Even taking public transportation often requires some walking. Smaller apartment houses have no elevators (电梯), and so people must climb stairs. City people can usually walk to local supermarkets. Since parking spaces are hard to find, there is often no alternative to walking.On the other hand, those who live in the country and suburbs do not have to walk every day. In fact, the opposite is often true. To go to school, work, or almost anywhere else, they must ride in cars.1). The Vienna survey may help to explain _______.A. the complaints of people in apartment housesB. the cause of Mrs. Groeger’s deathC. the longevity of people like Mrs. GroegerD. the image of cities in general-----------------选择：C2). The purpose of the second paragraph is to list some _______.A. benefits of walkingB. occasions for walking in city lifeC. comments made by city peopleD. problems of city living-----------------选择：B3).

People who live in the country probably do more driving than walking because _______.A. they don’t live near business areasB. they don’t n eed the exerciseC. they never have parking problemsD. they can’t afford to take the bus-----------------选择：A5). A conclusion that can be drawn from this passage is that _______.A. air pollution is not seriousB. anyone can live to be 107C. country people should move to the cityD. walking is a healthful exercise-----------------选择：D15秋学期《大学英语(三)》在线作业2阅读理解单选题完型填空二、单选题（共 15 道试题，共 45 分。
