Some people like working with people. However, others prefer jobs which mainly involve objects or machines.Those people who have the first preference believe working with people usually makes one feel interesting and efficient. In addition, they maintain people can be inspired to bring forward new ideas by communicating or consulting with those around them. However, still others have different preferences. In their opinions, working with objects or machines can make one enjoy more peace and quiet. Besides, they argue, under such peaceful conditions, one can do more practical work, improve his skill and make technical renovations.Weighing up these two kinds of work, I prefer working with people. For one thing, I like to cooperate with others and work in a team. For another, although there are competition and rivalry, we can learn something from other people. Considering these, I think, working with people is beneficial to our career development.【大学英语四级写作模拟题二】1.当前，社会上有很多私立学校和培训学校;2.私立学校的利与弊3.你的看法【范文】It can be noticed that a large number of private schools or training organizations become a new landscape in education.

There areprivate schools mainly dealing with foreign languages, computers, music and sports.However, is it a good or bad thing to have so many private schools? As a coin has two sides, so are the private schools. On the one hand, private schools can meet the special needs of the society or the particular requirements of people. On the other hand, they often bring people extra burden because of comparison and competition.When asked to decide whether we should have a society without private schools or a society with private schools, I will not hesitate a moment to prefer the latter. Although attending a training course will result in the extra cost or burden, it is of tremendous merits in preparing my work and cultivating my skills.【大学英语四级写作模拟题三】Directions: For this part, you are allowed 30minutes to write a short essay entitled OnVolunteering activities.

大学英语四级模拟试题一(附含答案解析)

大学英语四级模拟题一Part I Reading Comprehension (Skimming and Scanning) (10%) Directions:In this part, you will have 15 minutes to go over the passage quickly and answer the questions on the Answer Sheet.For questions 1-7, choose the best answer from the four choices marked A, B, C and D. For question 8-10, complete the sentences with the information given in the passage.Media Selection for AdvertisementsAfter determining the target audience for a product or service, advertising agencies must select the appropriate media for the advertisement. We discuss here the major types of media used in advertising. We focus our attention on seven types of advertising: television, newspapers, radio, magazines, out-of-home, Internet, and direct mail.TelevisionTelevision is an attractive medium for advertising because it delivers mass audiences to advertisers. When you consider that nearly three out of four Americans have seen the game show Who Wants to Be a Millionaire? You can understand the power of television to communicate with a large audience. When advertisers create a brand, for example, they want to impress consumers with the brand and its image. Television provides an ideal vehicle for this type of communication. But television is an expensive medium, and not all advertisers can afford to use it.Television’s influence on advertising is fourfold. First, narrowcasting means that television channels are seen by an increasingly narrow segment of the audience. The Golf Channel, for instance, is watched by people who play golf. Home and Garden Television is seen by those interested in household improvement projects. Thus, audiences are smaller and more homogeneous（具有共同特点的）than they have been in the past. Second, there is an increase in the number of television channels available to viewers, and thus, advertisers. This has also resulted in an increase in the sheer number of advertisements to which audiences are exposed. Third, digital recording devices allow audience members more control over which commercials they watch. Fourth, control over programming is being passed from the networks to local cable operators and satellite programmers.NewspapersAfter television, the medium attracting the next largest annual ad revenue is newspapers. The New York Times, which reaches a national audience, accounts for $1 billion in ad revenue annually. It has increased its national circulation（发行量）by 40% and is now available for home delivery in 168 cities. Locally, newspapers are the largest advertising medium.Newspapers are a less expensive advertising medium than television and providea way for advertisers to communicate a longer, more detailed message to their audience than they can through television. Given new production techniques, advertisements can be printed in newspapers in about 48 hours, meaning newspapers are also a quick way of getting the message out. Newspapers are often the most important form of news for a local community, and they develop a high degree of loyalty from local readers.RadioAdvertising on radio continues to grow. Radio is often used in conjunction with outdoor billboards（广告牌）and the Internet to reach even more customers than television. Advertisers are likely to use radio because it is a less expensive medium than television, which means advertisers can afford to repeat their ads often. Internet companies are also turning to radio advertising. Radio provides a way for advertisers to communicate with audience members at all times of the day. Consumers listen to radio on their way to school or work, at work, on the way home, and in the evening hours.Two major changes---satellite and Internet radio---will force radio advertisers to adapt their methods. Both of these radio forms allow listeners to tune in stations that are more distant than the local stations they could receive in the past. As a result, radio will increasingly attract target audiences who live many miles apart.MagazinesNewsweeklies, women’s titles, and business magazines have all seen increases in advertising because they attract the high-end market. Magazines are popular with advertisers because of the narrow market that they deliver. A broadcast medium such as network television attracts all types of audience members, but magazine audiences are more homogeneous. If you read Sports Illustrated, for example, you have much in common with the magazine’s othe r readers. Advertisers see magazines as an efficient way of reaching target audience members.Advertisers using the print media---magazines and newspapers---will need to adapt to two main changes. First, the Internet will bring larger audiences to local newspapers. These audiences will be more diverse and geographically dispersed（分散）than in the past. Second, advertisers will have to understand how to use an increasing number of magazines for their target audiences. Although some magazines will maintain national audiences, a large number of magazines will entertain narrower audiences.Out-of-home advertisingOut-of-home advertising, also called place-based advertising, has become an increasingly effective way of reaching consumers, who are more active than ever before. Many consumers today do not sit at home and watch television. Using billboards, newsstands, and bus shelters for advertising is an effective way of reaching these on-the-go consumers. More consumers travel longer distances to and from work, which also makes out-of-home advertising effective. Technology has changed the nature of the billboard business, making it a more effective medium than in the past. Using digital printing, billboard companies can print a billboard in 2 hours, compared with 6 days previously. This allows advertisers more variety inthe types of messages they create because they can change their messages more quickly.InternetAs consumers become more comfortable with online shopping, advertisers will seek to reach this market. As consumers get more of their news and information from the Internet, the ability of television and radio to get the word out to consumers will decrease. The challenge to Internet advertisers is to create ads that audience members remember.Internet advertising will play a more prominent role in organizations’ advertising in the near future. Internet audiences tend to be quite homogeneous, but small. Advertisers will have to adjust their methods to reach these audiences and will have to adapt their persuasive strategies to the online medium as well.Direct mailA final advertising medium is direct mail, which uses mailings to consumers to communicate a client’s message. Direct mail includes newsletters, postcards and special promotions. Direct mailis an effective way to build relationships with consumers. For many businesses, direct mail is the most effective form of advertising.1. Television is attractive advertising medium in that ________.A. it has large audiencesB. it appeals to housewivesC. it helps build up a company’s reputationD. it is affordable to most advertisers2. With the increase in the number of TV channels, ________.A. the cost of TV advertising has decreasedB. the number of TV viewers has increasedC. advertisers’ interest in other media has decreasedD. the number of TV ads people can see has increased3. Compared with television, newspaper as an advertising medium ________.A. earn a larger annual ad revenueB. convey more detailed messagesC. use more production techniquesD. get messages out more effectively4. Advertising on radio continues to grow because ________.A. more local radio stations have been set upB. modern technology makes it more entertainingC. it provides easy access to consumersD. it has been revolutionized by Internet radio5. Magazines are seen by advertisers as an efficient way to ________.A. reach target audiencesB. appeal to educated peopleC. attract diverse audiencesD. convey all kinds of messages6. Out-of-home advertising has become more effective because ________.A. billboards can be replaced within two hoursB. consumers travel more now than ever beforeC. such ads have been made much more attractiveD. the pace of urban life is much faster nowadays7.

It is common for students to practice their salesmanship when they have free time. However, I was extremely shocked when I learned one of our teachers had also joined in the profit-making business.She is our physical education teacher. The other day she publicly commented on the pimples (丘疹) on a student’s face and then presented the girl with a sample bottle of nameless face cream.According to the teacher, the face cream was produced in France. Each small bottle costs more than 40 yuan. From my viewpoint, it is a complete waste of money to buy such thing. “Why don’t you decline and refuse to buy it?” I suggested to the girl. She signed, “If I do that, I am afraid that my teacher may give me a lower mark in PE.” In other words, as long as she made a good deal with the teacher, an “excellent” on her PE course would follow.I was depressed. The teacher abused her social role. Her priority should be to give us proper education and training. Instead, she is trying to make a profit from us. She is unfit to be a good “engineer in cultivat ing the spirit of mankind”.47. The idea for students to do part-time jobs is _________.A. unheardB. uncommonC. surprisingD. not fresh48.

It was a very hot afternoon. The old man was pulling grass in his field when he felt a pain in his left hand. He at once realized that he had been bitten by a poisonous snake. In no time, he wrapped a cloth tightly around his arm to stop the poison spreading to the heart. Rushing home he shouted ‘Bring me the knife’. Minutes later the man lost his arm forever.”“The sad story touched me so much that I decided to devote myself to helping people bitten by snakes,” Shu said.52.

英语四级模拟试题及答案1Part I Reading Comprehension (共20小题，每小题2分，共40分)Directions: In this part there are four passages. Each passage is followed by four comprehension questions. Read the passage and answer the questions. Then mark your answer on the Answer Sheet.Passage 1Questions 1 to 5 are based on the following passage:In Washington D.C., 1600 Pennsylvania Avenue is a very special address. It is the address of the White House, the home of the president of the United States.Originally the White House was gray and was called the Presidential Palace. It was built from 1792 to 1800. at this time, the city of Washington itself was being built; it was to be the nation’s new capital city. George Washington, the first president, and Pierre Charles L’Enfant, a French engineer, chose the place for the new city. L’Enfant then planned they city. The presid ent’s home was an important part of the plan.A contest was held to pick a design for the president’s home. An architect named James Hoban won. He designed a large three-story house of gray stone.President Washington never lived in the President Palace. The first president to live there was John Adams, the secondpresident of the United States, and his wife Mrs. Adams did not really like hew new house. In her letters, she often complained about the cold. Fifty fireplaces were not enough to keep the house warm!In 1812 the United States and Britain went to war. In 1814 the British invaded Washington. Theu burned many buildings, including the Presidential Palace.After the war James Hoban, the original architect, partially rebuilt the president’s homes. To co ver the marks of the fire, the building was painted white. Before long it became known as the White House.The White House is one of the most popular tourist attractions in the United States. Every year more than 1.5 million visitors go through the five rooms that are open to the public.1. The White House was built in Washington .A. because a French engineer was invited to design itB. because President George Washington liked to live in itC. because the British invaders lived in it in 1812-1814D. because it was to be the nation’s capital city2. The Presidential Palace was .A. painted gray and whiteB. made of gray stoneC. made of white stoneD. made very warm in winter3. The president’s home and the city of Washington were .A. built by the American armyB. built by the British troopsC. planned by George WashingtonD. planned by the French4. The original home of the president needed to be rebuilt .A. because John Adam’s wife did not like itB. because it was cold in winter even with 50 fireplacesC. because it had burned down during the warD. because George Washington was not willing to live in it5. The new presidential home was painted white to .A. cover the marks of fireB. attract tourist from FranceC. to please Mrs. John AdamsD. keep it warm in winterPassage 2Questions 6 to 10 are based on the following passage:There are two kinds of memory: shot-term and long-term. Information in long-term memory can be remembered at a later time when it is needed. The information may be kept for days or weeks. However, information over and over. The following experiment shows how short-term memory has been studied.Henning studied how students who are learning English as a second language remember vocabulary. The subjects in his experiment were 75 college students. They represented all levels of ability in English: beginning, intermediate, and native-speaking students.To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered, each question had four choices. The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words that sound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning. Finally the subjects took a language proficiency test.Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning’s resultssuggest that beginning students hold the sound of words in their short-term memory, and advanced students hold the meaning of words in their short-term memory.6. Henning made the experiment in order to study .A. how students remember English vocabulary by short-term memoryB. how students learn English vocabularyC. how to develop students’ ability in EnglishD. how long information in short-term memory is kept7. Which of the following statements is TRUE according to the passage?A. Information in short-term memory is different from that in long-term memory.B. Long-term memory can be achieved only by training.C. It is easier to test short-term memory than long-term memory.D. Henning gave a separate test on vocabulary to his students.8. From Henning’s result we can see that .A. beginners have difficulty distinguishing the pronunciation of wordsB. advanced students remember words by their meaningC. it is difficult to remember words that sound alikeD. it is difficult to remember words that have the same meaning9. The word “subjects” in the passage means .A. memoryB. the theme of listening materialC. a branch of knowledge studiedD. the students experimented onPassage 3Questions 11 to 15 are based on the following passage:The cowboy is the hero of many movies,. He is, even today, a symbol of courage and adventure. But what was the life of the cowboy really like?The cowboy’s job is clear from the word cowboy. Cowboy were men who took care of cows and other cattle. The cattle were in the West and in Texas. People in the cities of the East wanted beef these cattle. Trains could take the cattle east. But first the cattle had to get to the trains. Part of the cowboy’s job was to take the cattle hundreds of miles to the railroad town. The trips were called cattle drivers. A cattle drive usually took several months. Cowboys rode for sixteen hours a day. Because they rode so much, each cowboy brought along about eight horses. A cowboy changed horses several times each day.The cowboys had to make sure that cattle arrived safely. Before starting on a drive, the cowboys branded the cattle. They burned a mark on the cattle to show who they belonged to. But these marks didn’t stop rustlers, or cattle thieves. Cowboys had to protect the cattle from rustlers. Rustlers made the dangerous trip even more dangerous.Even though their work was very difficult and dangerous, cowboys did not earn much money. They were paid badly. Yet cowboys liked their way of life. They lived in a wild and open country. They lived a life of adventure and freedom.11. A cowboy is a symbol of .A. courage and adventureB. a hard life and big payC. movies in the pastD. cows and other cattle12. The cowboys’ job was .A. to be a hero in real lifeB. to be a hero of the movieC. to take care of cattleD. to be a dangerous rustler13.

Cowboys enjoyed themselves because .A. they liked their way of lifeB. they made a lot of moneyC. they had a vary difficult jobD. they were heroes in moviesPassage 4Questions 16 to 20 are based on the following passage:Successful innovations have driven many older technologies to extinction and have resulted in higher productivity, greater consumption of energy, increased demand of raw materials, accelerated flow of materials through the economy and increased quantities of metals and other substances in use each person. The history of industrial development abounds with examples.In 1870, horses and mules were the prime source of power on U.S. farms. One horse or mule was required to support four human beings a ratio that remained almost constant for many decades. At that time, had a national commission been asked to forecast the population for 1970, its answer probably would have depended on whether its consultants were of an economic or technological turn of mind. Had they been “economists”, theywould probably have projected the 1970 horses or mule population to be more than 50 million. Had they been “technologists”, they would have recognized that the power of steam had already been harnessed to industry and to learn and ocean transport. They would have recognized further that it would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.16. According to the passage, what supplied most of the power on U.S. farms in 1870?A. AnimalsB. HumansC. EnginesD. Water17. Which of the following is NOT mentioned by the author as a consequence of new technological developments?A. Older technologies die away.B. The quality of life is Improved.C.

It can be inferred from the passage that by 1870 .A. technology began to be more economicalB. the steam engine had been inventedC. the U.S. horse population was about 10 millionD. a national commission was about 10 million19. In the second paragraph, the author suggests that “economists” would .A. plan the economy through yearly forecastsB. fail to consider the influence of technological innovationC. value the economic contribution of farm animalsD. consult the national commission on the economy20. What is the author’s attitude toward changes brought on by technological innovations?A. He is excited about them.B. He accept them as natural.C. He is disturbed by them.D. He questions their usefulness.Questions 16 to 20 are based on the following passage:This semester I began to have a series of teacher nightmares, something that had not happened to me for years, not since my first year of teaching when I was in a perpetual state of dread. I would be rushing to get to class on time, trying to gather up notes from a maelstrom of papers on my desk, not certain what subject we were covering today, indeed not even certain what course I was teaching. My heart was pounding. I was late. I would not find my notes. A hundred people were waiting for me in the classroom, their pens poised to take down my every syllable, and I had nothing to say. Them Mr. Winthrop’s big blonde face with those dark eyes would loom at the door of my office, and with that mocking grin, he would say, “Pro fessor, the class is waiting for you,” and I would faint dead onto the floor. Or sometimes in my dream I would make it to the podium (讲台), start to lecture on some aspect of criminal law or causation, only to have Mr. Winthrop raise his hand, and without even waiting to be called upon, presumably ask a question. Presumably because I could not make out his words. I could see his mouth moving underneath his baseball cap, and muffled sounds resounded in my ears, but I could not understand him. All eyes in the classroom were on me, and my students began to laugh, but not Mr. Winthrop. He continued to move his mouth, and I felt as if I was watching TV with the sound off except that my head was all a buzz with the laughter and the shuffling of feet as my students exited in disgust. Again, I ended the nightmare by fainting dead away onto the floor, and then I would wake up, my sheets damp from desperation. It was enough to make a man get out of bedand mix a drink at four in the morning even if he had the eight o’cl ock class.16. From this passage, it is indicated that .A. the first year of teaching is unforgettable and frightening for me foreverB. nightmares have happened to me more often than not since my first year of teachingC. in my first year of teaching, I was always full of fearsD. as a teacher, I feel uneasy all the time17. Which of the following statements is TRUE?A. I was quite clear about the subject I was to deal with before class.B. I would give the lectures on time.C. I prepared the notes carefully before class. However, I forgot to take them with me to the classroom.D. My heart was beating faster and faster before class.18. Mr. Winthrop is .A. a presumable studentB. a baseball loverC. the student who often teases the teacherD. the student who answers the teacher’s question in a humorous way19. In my nightmare, it would happen to me except that .A. I sometimes was very calm to see that my students were in disguiseB. when I gave the lecture, Mr. Minthrop was the only student to ask a questionC. I often fall down to the floor losing my consciousness before I woke upD. I would rather wake up to have a good drink in the earlymorning than have the nightmare20. The tone of this passage is .A. provokingB. sensationalC. desperateD. profoundPart II Vocabulary and Structure (共40小题，每小题1分，共40分)Directions: In this part there are forty incomplete sentences.

大学英语四级阅读理解模拟试题及答案

大学英语四级阅读理解模拟试题及答案大学英语四级阅读理解模拟试题及答案「篇一」1. C 细节题。

因为Leadville可以为Tabor带来巨富。

这一点不是Leadville得名的原因，因为在文章第二段中，讲到这一点时，提及三个原因：A.因为Tabor成为当地的居民代表人物，B.因为在Leadville有丰富的铅的储藏量。

D.因为Leadville是因为Tabor重要而起的名。

2. D 词汇题。

第二段中grubstake的词义与D所述内容是相同的，即“供给探矿者资金，衣物，食品以及其他物品”。

3. A 细节题。

Tabor第一次真正发财是他为两名矿工提供资助，为此他获得他们矿资源三分之一的股份。

见文章第三段4-9行内容：两名开矿者从Tabor那儿借走价值17美元的物品，作为回报，Tabor获得他们矿资源三分之一股份。

于是两位开矿者在一座山旁的不毛之地开始挖掘，九天之后，发现了银的富矿，于是Tabor又将两人的.股份全买下，这样，银矿属于Tabor一个人所有，这个矿就是后来著名的“匹兹堡”矿。

Tabor用17美元的投资换来了130万美元的收获。

4. B 推断题。

由原文可知泰勃的财产来源是有一定偶然性的，但是毕竟也是基于他开创“grubstake”模式，因为A、D都不对，C更是没有根据，因为他还没有娶第二位夫人这一切就发生了。

分析泰勃的做法，会得出B选项所示的结论。

5. B 推断题。

如果本文是一篇文章的第一部分，那么在文章的第二部分将介绍谁呢?可以从文章第一句分析出来，在Leadville的黄金年代，其多彩的特点当中，Tabor及其第二任妻子Elizabeth McCourt是值得大书特书的，接着，文章都在讲述有关H.A.W.Tabor发家致富的历史，如先买下匹兹堡矿，后又买下Matchless矿，最后成为市长，代理州长，等等，所以涉及到的全是男主人公，因此下边再讲的话，应成为女主人公即Elizabeth McCourt的天地了，她是Tabor的第二任妻子。
