外国语学院大学外语教学部2009年8月2009级《大学英语》分级考试试卷Part I. Reading Comprehension (40%)Directions:Read the following passages and choose the best answer to each of the questions or incomplete statements following the passage. You must read the four choicesmarked A, B, C and D, and decide which is the best answer. Then mark thecorresponding letter on the Answer Sheet with a single line through the center.(2’×20)Passage 1Questions 1 to 5 are based on the following passage.It has been a widespread belief that the American family is dying. But a new study reveals that the American family is stronger than ever. This study affords surprising evidence of the persistence of American commitments to family life.The American family is changing, not dying. It is becoming smaller, men and women are becoming more equal, and the divorce rate is higher. But despite the high divorce rate, marriage has never been more popular. The majority of divorced people remarry, but only 2% marry more than twice. Most marriages last a long time, and a large proportion of divorces are from teenage marriages. Depending on the specific situation, there’s often good reason for teenage marriages to break up.There is no evidence that children receive less attention from mothers who work outside the home than from mothers working inside the home. So far the amount of educational or development time hasn’t varied very much, whether or not the mother works outside the home. In fact, working mothers try to make up for it by setting aside time only for their children.The study shows that television is by far the most significant new childcare arrangement of this century. The most important activity for children up to age 14 is watching television.School is the second most time-consuming activity for children. They spend an average of about 19 hours a week in school. A larger proportion of children go to school earlier than ever before, and they stay in school longer. Another big change is that the proportion of very young children in daycare centers (日托站) has almost doubled in recent years. Compared with these two dramatic changes in child activity, the changes caused by mothers working outside the home appear very small.1 The main idea of this article is that _______.A. the American family is dyingB. young people today don’t want to get marriedC. the American family is changing, but it is stronger than everD. education has resulted in dramatic changes in the American family2 Which of the following statements is NOT true?A. Marriage is more popular than before.B. Many divorced people remarry.C. The majority of marriages last long.D. Working mothers devote less time to their children.3 The author of this article believes that ________.A. the American family is here to stayB. children should not watch so much televisionC. mothers should not work when their children are smallD. teenage marriages should be encouraged4 What is the most significant new childcare arrangement of this century?A. The daycare center.B. Television.C. The school.D. Development time.5 According to the writer, which two major factors have led to the belief that the Americanfamily is dying?A. The divorce rate is high and working mothers neglect their children.B. The divorce rate is high and children care more about television than anything else.C. Divorces are increasing and many teenage marriages break up.D. Children stay in school longer and mothers have little time to take care of them. Passage 2Questions 6 to 10 are based on the following passage.What you give your relatives, friends, husband, or wife can help you know yourself better. Also, what they give you can tell you something about their personality. Most gift-giving (and getting) shows nothing more than the spirit of love and friendship. But it is possible to form some associations between the kinds of things bought and the people who buy them. Here is a guide to who gives you wha t --- and why.The clothes you wear tell something about your personality. They tell the world not only how you want to be seen but how you see yourself as well. When someone gives you something to wear that agrees with your self-image, they’re saying, “I agree with you. I like you the way you are.” Such a gift should be taken as a form of compliment. On the other hand, a gift of clothing that does not match your personality could be an insult to your character.Making something by hand has become the exception in many countries toda y－so much so that giving a homemade gift is sometimes considered unusual. If you receive a homemade gift, you’re lucky. It may not be made perfectly, but it will show a certain quality of love. People who give homemade gifts may be said to be very generous. They are given time and emotion, two important characteristics of being creative.A person who thinks of food when thinking of a gift is good example of what human warmth means. Whether you give a box of chocolates, a bag of oranges, or a ball of cheese, all carry the same message of comfort and support.People who give books as gifts either like reading or would like everyone to think they do. If you happen to receive a large, heavy book, this giver may be much more interested in the way things appear than in the way they actually are. Of course, reading is a way of feeling the emotions of another person and of learning new things. Giving a book can be a way of sharing a feeling or a newly learned meaning. The giver is probably trying to say to you what the book said to him.6 The first paragraph is written to tell readers that ________.A. the gifts you give can help you understand yourself betterB. the gifts you receive are helpful for you to know the personality of those who give themC. gifts can show friendship and loveD. there is a certain relationship between the kinds of gifts and the people who give them7 A person who likes the self-image of another person will give the latter ________.A. clothesB. a homemade giftC. a gift that agrees with the personality of the receiverD. a gift that matches the character of the giver8 Which of the following statements is NOT true according to the passage?A. What you wear can tell something about your personality.B. Homemade gifts are not welcomed in some countries.C. People who give books as gifts either like reading or would like everyone to think they do.D. Reading books given to you as gifts can be a way of sharing a feeling with the giver.9 If you give a large, heavy book as a gift, it may show that _________.A. you are knowledgeableB. the receiver is interested in readingC. you dislike readingD. you are more interested in the appearance of the book than in its contents10 People who want to show their love towards others often give _______.A. homemade giftsB. delicious foodC. expensive clothesD. interesting booksPassage 3Questions 11 to 15 are based on the following passage.My love of nature goes right back to my childhood, to the times when I stayed on my grandparent’s f arm in Suffolk. I think it was my grandmother who encouraged me more than anyone: she taught me the names of wildflowers and got me interested in looking at the countryside, so it seemed obvious to go on to do zoology at university.I didn’t get my first camera until after I’d graduated, when I was due to go diving in Norway and needed a method of recording the sea creatures I would find there. My father didn’t know anything about photography, but he bought me an Exacta, which was really quite a good camera for the time, and I went off to take my first pictures of sea starfish. I became keen very quickly, and I learnt how to develop and print.I’ve tried from the beginning to produce pictures which are always biologically correct. There are people who will alter things deliberately: you don’t pick up sea creatures from the middle of the shore and take them down to attractive pools at the bottom of the shore without knowing you’re doing it.There can be a lot of ignorance in people’s behavior towards wild animals and it’s a problem that more and more people are going to wild places: while some animals may get used to cars, they won’t get used to people suddenly rushing up to them. The sheer pressure of people, coupled with the fact that there are increasingly few places where no one else has photographed, means that over the years, life has become much more difficult for the professional wildlife photographers.Nevertheless, wildlife photographers play a very important part in educating people about what is out there and what needs conserving. Although photography can be an enjoyable pastime, as it is to many people, it is also something that plays a very important part in educating young and old alike.11 The author decided to go to university and study zoology because _______________.A. she wanted to improve her life in the countrysideB. she was persuaded to do so by her grandmotherC. she was keen on the natural worldD. she wanted to stop moving around all the time12 How is the author different from some of the other wildlife photographers she meets?A. She tries to make her photographs as attractive as possible.B. She takes photographs which record accurate natural conditions.C. She likes to photograph plants as well as wildlife.D. She knows the best places to find wildlife.13 The author now finds it more difficult to photograph wild animals because ______________.A. there are fewer of themB. they have become more nervous of peopleC. it is harder to find suitable placesD. they have become frightened of cars14 According to the author, wildlife photography is important because it can make people realizethat ___________________.A. photography is an enjoyable hobbyB. we learn little about wildlife at schoolC. it is worthwhile visiting the countrysideD. it is important to look after wild animals15 Which of the following describes the author?A. Proud.B. Sensitive.C. Aggressive.D. Disappointed.Passage 4Questions 16 to 20 are based on the following passage.If you have been joining in chat room conversations, or trading e-mail with net pals, you have become one of the millions who write in a special, short form of English.Throughout the world, every night children and their elders are “talking”onlin e－many of them are talking at the same time.It is fast: trying talking to six people at once. It is convenient: three or four words per exchange. It takes cleverness, concentration and quick fingers.And it requires very simple language. There’s neither time nor space for explanations. Why waste precious key-strokes telling six friends you have to leave for a moment to take care of your little brother when BRB(= be right back) will do?Want to enter a conversation? Just type PMFJI (= pardon me for jumping in).Interested in whom you’re talking to? Type A/S/L, the common request to know your pal’s age, sex and location. You may get 15/M/NY as a reply from your pal.If something makes you laugh, say you’re OTF (= on the floor), or LOL (= laughing out loud), or join the two into ROTFL (= rolling on the floor laughing).And when it’s time to get back to work or go to bed, you type GTG (= got to go) or TTYL (= talk to you later).People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital letters are left in the dust, except when expressing feelings, as it takes more time to hold down the “shift” key and use capitals. Punctuation is going, too.16 When people are online, they talk by_____.A. using body language.B. drawing some strange picturesC. making phone calls17 Internet makes many people in the world ______.A. talk at the same timeB. discover their friends and relativesC. pick out good things to buyD. find out about some problems in societyD. making use of an especially short form of English18 The underlined sentence “There’s neither time nor space for explanation”(L.1, para. 4)means that _____.A. people should use words properlyB. people should know what time it is when they are talkingC. people online have to express themselves in a simple wayD. people should communicate in a funny way19 If you get 19/M/HK as an answer to your A/S/L, it means ______.A. the person who is talking to you is 19 from Hong Kong and he is highB. you are talking to a boy 19 years old and he lives in Hong KongC. you are talking to 19 boys from Hong Kong at the same timeD. the boy from Hong Kong has been online for 19 minutes20 Which of the following is a way to save online time?A. People seldom use capital letters or punctuation marks.B. Many people draw pictures.C. People only use the mouse instead of the keyboard.D. People never use the “shift” key.Part II.

外国语学院大学外语教学部2009年8月2009级《大学英语》分级考试试卷Part I. Reading Comprehension (40%)irections: Read the following passages and choose the best answer to each of the questions or incomplete statements following the passage. You must read thefour choices marked A, B, C and D, and decide which is the best answer. Thenmark the corresponding letter on the Answer Sheet with a single line throughthe center.(2’×20)Passage 1Questions 1 to 5 are based on the following passage.It has been a widespread belief that the American family is dying. But a new study reveals that the American family is stronger than ever. This study affords surprising evidence of the persistence of American commitments to family life.The American family is changing, not dying. It is becoming smaller, men and women are becoming more equal, and the divorce rate is higher. But despite the high divorce rate, marriage has never been more popular. The majority of divorced people remarry, but only 2% marry more than twice. Most marriages last a long time, and a large proportion of divorces are from teenage marriages. Depending on the specific situation, there’s often good reason for teenage marriages to break up.There is no evidence that children receive less attention from mothers who work outside the home than from mothers working inside the home. So far the amount of educational or development time hasn’t varied very much, whether or not the mother works outside the home. In fact, working mothers try to make up for it by setting aside time only for their children.The study shows that television is by far the most significant new childcare arrangement of this century. The most important activity for children up to age 14 is watching television.School is the second most time-consuming activity for children. They spend an average of about 19 hours a week in school. A larger proportion of children go to school earlier than ever before, and they stay in school longer. Another big change is that the proportion of very young children in daycare centers (日托站) has almost doubled in recent years. Compared with these two dramatic changes in child activity, the changes caused by mothers working outside the home appear very small.1 The main idea of this article is that _______.A. the American family is dyingB. young people today don’t want to get marriedC. the American family is changing, but it is stronger than everD. education has resulted in dramatic changes in the American family2 Which of the following statements is NOT true?A. Marriage is more popular than before.B. Many divorced people remarry.C. The majority of marriages last long.D. Working mothers devote less time to their children.3 The author of this article believes that ________.A. the American family is here to stayB. children should not watch so much televisionC. mothers should not work when their children are smallD. teenage marriages should be encouraged4 What is the most significant new childcare arrangement of this century?A. The daycare center.B. Television.C. The school.D. Development time.5 According to the writer, which two major factors have led to the belief that the Americanfamily is dying?A. The divorce rate is high and working mothers neglect their children.B. The divorce rate is high and children care more about television than anything else.C. Divorces are increasing and many teenage marriages break up.D. Children stay in school longer and mothers have little time to take care of them. Passage 2Questions 6 to 10 are based on the following passage.What you give your relatives, friends, husband, or wife can help you know yourself better. Also, what they give you can tell you something about their personality. Most gift-giving (and getting) shows nothing more than the spirit of love and friendship. But it is possible to form some associations between the kinds of things bought and the people who buy them. Here is a guide to who gives you wha t --- and why.The clothes you wear tell something about your personality. They tell the world not only how you want to be seen but how you see yourself as well. When someone gives you something to wear that agrees with your self-image, they’re saying, “I agree with you. I like you the way you are.” Such a gift should be taken as a form of compliment. On the other hand, a gift of clothing that does not match your personality could be an insult to your character.Making something by hand has become the exception in many countries toda y－so much so that giving a homemade gift is sometimes considered unusual. If you receive a homemade gift, you’re lucky. It may not be made perfectly, but it will show a certain quality of love. People who give homemade gifts may be said to be very generous. They are given time and emotion, two important characteristics of being creative.A person who thinks of food when thinking of a gift is good example of what human warmth means. Whether you give a box of chocolates, a bag of oranges, or a ball of cheese, all carry the same message of comfort and support.People who give books as gifts either like reading or would like everyone to think they do. If you happen to receive a large, heavy book, this giver may be much more interested in the way things appear than in the way they actually are. Of course, reading is a way of feeling the emotions of another person and of learning new things. Giving a book can be a way of sharinga feeling or a newly learned meaning. The giver is probably trying to say to you what the book said to him.6 The first paragraph is written to tell readers that ________.A. the gifts you give can help you understand yourself betterB. the gifts you receive are helpful for you to know the personality of those who givethemC. gifts can show friendship and loveD. there is a certain relationship between the kinds of gifts and the people who givethem7 A person who likes the self-image of another person will give the latter ________.A. clothesB. a homemade giftC. a gift that agrees with the personality of the receiverD. a gift that matches the character of the giver8 Which of the following statements is NOT true according to the passage?A. What you wear can tell something about your personality.B. Homemade gifts are not welcomed in some countries.C. People who give books as gifts either like reading or would like everyone to thinkthey do.D. Reading books given to you as gifts can be a way of sharing a feeling with the giver.9 If you give a large, heavy book as a gift, it may show that _________.A. you are knowledgeableB. the receiver is interested in readingC. you dislike readingD. you are more interested in the appearance of the book than in its contents10 People who want to show their love towards others often give _______.A. homemade giftsB. delicious foodC. expensive clothesD. interesting booksPassage 3Questions 11 to 15 are based on the following passage.My love of nature goes right back to my childhood, to the times when I stayed on my grandparent’s farm in Suffolk. I think it was my grandmother who encouraged me more thananyone: she taught me the names of wildflowers and got me interested in looking at the countryside, so it seemed obvious to go on to do zoology at university.I didn’t get my first camera until after I’d graduated, when I was due to go diving in Norway and needed a method of recording the sea creatures I would find there. My father didn’t know anything about photography, but he bought me an Exac ta, which was really quite a good camera for the time, and I went off to take my first pictures of sea starfish. I became keen very quickly, and I learnt how to develop and print.I’ve tried from the beginning to produce pictures which are always biologic ally correct. There are people who will alter things deliberately: you don’t pick up sea creatures from the middle of the shore and take them down to attractive pools at the bottom of the shore without knowing you’re doing it.There can be a lot of ignora nce in people’s behavior towards wild animals and it’s a problem that more and more people are going to wild places: while some animals may get used to cars, they won’t get used to people suddenly rushing up to them. The sheer pressure of people, coupled with the fact that there are increasingly few places where no one else has photographed, means that over the years, life has become much more difficult for the professional wildlife photographers.Nevertheless, wildlife photographers play a very important part in educating people about what is out there and what needs conserving. Although photography can be an enjoyable pastime, as it is to many people, it is also something that plays a very important part in educating young and old alike.11 The author decided to go to university and study zoology because _______________.A. she wanted to improve her life in the countrysideB. she was persuaded to do so by her grandmotherC. she was keen on the natural worldD. she wanted to stop moving around all the time12 How is the author different from some of the other wildlife photographers she meets?A. She tries to make her photographs as attractive as possible.B. She takes photographs which record accurate natural conditions.C. She likes to photograph plants as well as wildlife.D. She knows the best places to find wildlife.13 The author now finds it more difficult to photograph wild animals because______________.A. there are fewer of themB. they have become more nervous of peopleC. it is harder to find suitable placesD. they have become frightened of cars14 According to the author, wildlife photography is important because it can make peoplerealize that ___________________.A. photography is an enjoyable hobbyB. we learn little about wildlife at schoolC. it is worthwhile visiting the countrysideD. it is important to look after wild animals15 Which of the following describes the author?A. Proud.B. Sensitive.C. Aggressive.D. Disappointed.Passage 4Questions 16 to 20 are based on the following passage.If you have been joining in chat room conversations, or trading e-mail with net pals, you have become one of the millions who write in a special, short form of English.Throughout the world, every night children and their elders are “talking” onlin e－many of them are talking at the same time.It is fast: trying talking to six people at once. It is convenient: three or four words per exchange. It takes cleverness, concentration and quick fingers.And it requires very simple language. There’s neither time nor space for explanations. Why waste precious key-strokes telling six friends you have to leave for a moment to take care of your little brother when BRB(= be right back) will do?Want to enter a conversation? Just type PMFJI (= pardon me for jumping in).Interested in whom you’re talking to? Type A/S/L, the common request to know your pal’s age, sex and location. You may get 15/M/NY as a reply from your pal.If something makes you laugh, say you’re OTF (= on the floor), or LOL (= laughing out loud), or join the two into ROTFL (= rolling on the floor laughing).And when it’s time to get back to work or go to bed, you type GTG (= got to go) or TTYL (= talk to you later).People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital letters are left in the dust, except when expressing feelings, as it takes more time to hold down the “shift” key and use capitals. Punctuation is going, too.16 When people are online, they talk by_____.A. using body language.B. drawing some strange picturesC. making phone callsD. making use of an especially short form of English17 Internet makes many people in the world ______.A. talk at the same timeB. discover their friends and relativesC. pick out good things to buyD. find out about some problems in society18 The underlined sentence “There’s neither time nor space for explanation”(L.1, para. 4)means that _____.A. people should use words properlyB. people should know what time it is when they are talkingC. people online have to express themselves in a simple wayD. people should communicate in a funny way19 If you get 19/M/HK as an answer to your A/S/L, it means ______.A. the person who is talking to you is 19 from Hong Kong and he is highB. you are talking to a boy 19 years old and he lives in Hong KongC. you are talking to 19 boys from Hong Kong at the same timeD. the boy from Hong Kong has been online for 19 minutes20 Which of the following is a way to save online time?A. People seldom use capital letters or punctuation marks.B. Many people draw pictures.C. People only use the mouse instead of the keyboard.D. People never use the “shift” key.Part II.

C. Manufacturing Cells (Group Technology)(Familyof Parts Concept)The use of manufacturing cells represents a particular kind of factory layout for manufacturing equipment. The essence of the concept is that, when manufacturing a particular part or family of similar parts in substantial quantities, the equipment for successive operations on the part should be grouped together. The operator - or team of operators who make that part (or the family of parts) - operate all the equipment in the cell. This arrangement is in contrast to a more traditional factory layout that groups like equipment together in departments. Then parts move from departmentto department for each operation. The advantage of the cell layout is that lines of communication and transportation are made very short. The factory's through-put rate is speeded; work-in-process inventory is greatly reduced; when problems arise at one operation, their effect on subsequent operations is immediately recognized. Route sheets to control movement of parts through the factory are greatly simplified or not needed. Operators learn what is needed at each operation to avoid problems at subsequent operations and have the satisfaction of seeing the results of their efforts.Quality tends to improve. The dis-advantage is that C.制造单元（成组技术）（零件族概念）制造单元的使用代表生产设备一种特殊的工厂布局方式。

A few years ago it was common to speak of a generation gap between young people and their elders. Parents said that children did not respect and listen to them, while children said that their parents did not understand them at all. What had gone wrong? Why had the generation gap suddenly appeared? Actually, the generation gap has been around for a long time. Many people argue that it is built into every part of our society.

南京邮电大学通达学院 2011/2012学年第一学期《专业英语（自学）》期末大作业专业班级学号姓名Writing（100分）You will find several topics in the following lists. Please choose one of them and write a short paper to explain your own opinion.Requirements:(1) Name the paper by yourself;(2) Your own opinion should be clearly put forward.(3)Try to find some articles via the internet or journals as references.(4) More than 1200 words.Topics:0．“People often complain that products are not made to last. They feel that making products that wear out fairly quickly wastes both natural and human resources. What they fail to see, however, is that such manufacturing practices keep costs down for the co nsumer and stimulate demand.”Which do you find more compelling: the complaint about products that do not last or the response to it? Explain your position using relevant reasons and/or examples drawn from your own experience, observations, or reading.1．“Manufacturers are responsible for ensuring that their products are safe. If a product injures someone, for whatever reason, the manufacturer should be held legally and financially accountable for the injury.” Discuss the extent to which you agree or disagree with the opinion expressed above. Support your point of view with reasons and/or examples from your own experience, observations, or reading.2．Analysis of Issue Questions: “Studies have found that employees of not-for-profit organizations and charities are often more highly motivated than employees of for-profit corporations to perform well at work when their performance is not being monitored or evaluated. Interviews with employees of not-for-profit organizations suggest that the reason fortheir greater motivation is the belief that their work helps to improve society. Because they believe in the importance of their work, they have personal reasons to perform well, even when no financial reward is present. Thus, if our corporation began donating a significant portion of its profits to humanitarian causes, our employees’ motivation and productivity would increase substantially and our overall pr ofits would increase as well.” What do you think about this point? Explain why?3．“All companies should invest heavily in advertising because high-quality advertising can sell almost any product or service.”Discuss the extent to which you agree or disagree with the opinion expressed above. Support your point of view with reasons and/or examples from your own experience, observations, or reading.4．Analysis of Issue Questions: “Employers should have no right to obtain information about their employees’ health or other aspects of their personal lives without the employees’permission.” Which opinion do you prefer? Explain why?5．Analysis of Issue Questions: “Businesses and other organizations have overemphasized the importance of working as a team. Clearly, in any human group, it is the strong individual, the person with the most commitment and energy, who gets things done.” Which opinion do you prefer? Explain why?6．“Instead of relying on the advice of outside experts, organizations should place greater val ue on the advice that can come only from their own highly experienced employees.” Discuss the extent to which you agree or disagree with the opinion stated above. Support your views with reasons and/or examples from your own experience, observations, or reading.7．“When judging the qualifications of potential employees, business employers should rely solely on objective information, such as a candidate’s résumé and education. Personal interviews are much too subjective and are therefore not a valid basis on which to judge a person’s qualifications for a job.”Discuss the extent to which you agree or disagree with the opinion stated above. Support your views with reasons and/or examples from your own experience, observations, or reading.8．“Most people today place t oo much emphasis on satisfying their immediate desires. The overall quality of life would be greatly improved if we all focused instead on meeting our long-term needs.”Discuss the extent to which you agree or disagree with the opinion stated above. Support your views with reasons and/or examples from your own experience, observations, or reading.9．Analysis of Issue Questions: “If the primary duty and concern of a corporation is to make money, then conflict is inevitable when the corporation must also acknowledge a duty to serve society.” Which opinion do you prefer? Explain why?Teamwork Is Most ImportantToday's society, with the knowledge economy era, all kinds of knowledge and technology continued to emerge, competition is increasingly intense. More diverse needs of the community, so that people face in work and study in the circumstances and environment is extremely complex. In many cases, individual ability alone is very difficult to completely deal with complex issues and take effective and efficient operations. All of these require people to form groups and ask each other to rely on further between members, interrelated and work together to establish cooperative teams to solve complex problems, and coordinate the necessary actions. The development team's response capabilities and sustained innovation rely on the power of teamwork to create a miracle..Ordering by the first wolf and other wolves in its place. The facilities of its staff, howling sound of the ups and downs and interactive, with the tacit understanding, are orderly and not chaotic Wolfs' head snarl. The main who courageously forward and feint, and then were evasive action, those who snapped back and howl with its strong . Lone wolf is not strong, but the collective strength of the wolf to appear before the target, but the performance of a powerful attack. The success of wolf hunting process in a number of factors, the strict order of collective organization and efficient teamwork is one of the most obvious and important factor. This shows the importance of teamwork.Team not only emphasizes the individual's work, more emphasis on the team's overall performance. Team is not only relies on the collective discussion and decision-making but also strengthen information sharing and standards. which emphasizes the contributions by members to gain real collective results, the team is greater than the parts sum. The core team is a common devotion. This requires a common dedication to convince members to whom the target. Only a practical and a challenging target in order to stimulate the team's motivation and dedication, boundless energy into the work. So the team is to achieve the objectives set by the apparent voluntary cooperation and concerted efforts of the spirit. It can mobilize all the resources of team members and intelligence, and will automatically get rid of all the discord and injustice, and it will give those sincere and selfless dedication by an appropriate return. If the team is out voluntarily, it will produce a powerful and enduring force.Teamwork describes both qualitative and functional characteristics when two or more people begin to act like a team. The qualitative meaning of the team is apparent in such everyday expressions as :'we worked closely together', 'we always helped each other', 'we were all focused on a common goal', 'it was a team effort, everyone contributed', and the like. The qualitative meaning of teamwork is that it describes two or more people who are closely knit around a common purpose, whowork easily together, who exhibit a good bit of trust toward each other who respect each other and who have positive work relationships. The functional meaning of teamwork is that it describes that condition in which no one person can produce a specified result or perform a specified task. Teamwork here means only that two or more people worked together and produced something that could not be achieved by one person alone. It does not describe how well they worked together, but only that they co-operated sufficiently to perform their work.Through teamwork, you can create a working atmosphere, so that each team has a sense of belonging, help to improve team members' enthusiasm and efficiency. The so-called men and women are not tired with work, the first Leaving aside the men and women, even men and male cooperation, not because a man in combat and have a sense of loneliness. As the team has a goal of consistency, resulting in an overall sense of belonging. It is this sense of belonging so that each member feels for the team effort but also for their own goals, as well as other members together for this goal to stimulate a stronger incentive to work, so the target initiative will contribute with their own wells, which makes the efficiency higher than when the individual alone.Through teamwork, team members will help to stimulate the motivation to help improve the team's overall capacity. Most people's heart has hope others respect their desire to have unyielding psychological and have the desire to keep improving. These psychological factors are unconsciously motivated to enhance the members, so that members are not conscious of the demands on themselves to progress and strive to be the best team to win the respect of other employees. When there is no best time to do the above that psychological factors can promote competition between members and strive with the best team members in line in order to achieve the incentive function. In this constantly motivate them to help improve the team's overall capacity. Team members are internal competition. There is a certain degree of excitation , and this comes from the psychological desire among team members, but this desire to control, among team members to avoid personal heroism affect the team's overall combat capability.The model does not view team development and performance as finally dependent on such variable as the nature of the task and quality of the environment. The model communicates the view that team development and performance are largely a function of a work unit's decision to be a team regardless of such variables as task and environment. The model couples development with performance. The issues for team environment are the same. Team development and team performance occur together. The more highly developed the team becomes, the better the team performance.Team will help generate new ideas. That everyone has their own strengths and weaknesses. Each person has their own unique ideas. Team members help togenerate different kinds of diverse ideas and thus help in brainstorming and decision-making when you can produce a better solution.Teamwork can be constrained by the team members to regulate and control behavior. When a person is not the same with others, this formed within the team concept that power will impose a visible and invisible pressures , would have led him to produce a depression in the psychological sense of urgency . Under this pressure, along with members of the public unknowingly in the sense judgments and actions on the show and the team's most consistent in order to bind to regulate and control the behavior of individual purpose. Regulate and control the behavior of individual actions contribute to the standardization organizations.It can help to improve team efficiency.Teamwork can help to improve decision-making efficiency. Team and general groups, the relatively small number of teams, which will help reduce the information transfer process in the absence of conducive to communication between team members, help to improve the team members involved in the decision-making initiative. The concept of leadership also relatively strong in the teams. Team members is relatively flat, which is conducive to the formation of democratic decision-making.Everyone has their own into the collective in order to give full play to the role of individuals. In short, the team spirit of any organization is indispensable in terms of the essence. Otherwise, just like a mess; A chopstick is easy to break, the ten chopsticks is difficult to break . This is the power of teamwork importance of visual expression, and this is my understanding of teamwork. Team spirit is important rules.。

飞动专业英语阅读大作业班级：0906102学号：090610223姓名：马康康日期：2012年4月5日ENERGY TRANSFER FROM GAS FLOW TO TURBINE6. From the description contained in para. 1, it will be seen that the turbine depends for its operation on the transfer of energy between the combustion gases and the turbine. This transfer is never 100 percent because of thermodynamic and mechanical losses, (para. 11).7. When the gas is expanded by the combustion process (Part 4), it forces its way into the discharge nozzles of the turbine where, because of their convergent shape, it is accelerated to about the speed of sound which, at the gas temperature, is about 2,500 feet per second. At the same time the gas flow is given a 'spin' or 'whirl' in the direction of rotation of the turbine blades by the nozzle guide vanes. On impact with the blades and during the subsequent reaction through the blades, energy is absorbed, causing the turbine to rotate at high speed and so provide the power for driving the turbine shaft and compressor.8. The torque or turning power applied to the turbine is governed by the rate of gas flow and the energy change of the gas between the inlet and the outlet of the turbine blades, The design of the turbine is such that the whirl will be removed from the gas stream so that the flow at exit from the turbine will be substantially 'straightened out' to give an axial flow into the exhaust system (Part 6). Excessive residual whirl reduces the efficiency of the exhaust system and also tends to produce jet pipe vibration which has a detrimental effect on the exhaust cone supports and struts.9. It will be seen that the nozzle guide vanes and blades of the turbine are 'twisted', the blades having a stagger angle that is greater at the tip than at the root (fig. 5-6). The reason for the twist is to make the gas flow from the combustion system do equal work at all positions along the length of the blade and to ensure that the flow enters the exhaust system with a uniform axial velocity. This results in certain changes in velocity, pressure and temperature occurring through the turbine, as shown diagram-matically in fig. 5-7.10. The 'degree of reaction' varies from root to tip, being least at the root and highest at the tip, with the mean section having the chosen value of about 50 percent.11. The losses which prevent the turbine from being 100 per cent efficient are due to a number of reasons. A typical uncooled three-stage turbine would suffer a 3.5 per cent loss because of aerodynamic losses in the turbine blades. A further 4.5 per cent loss would be incurred by aerodynamic losses in the nozzle guide vanes, gas leakage over the turbine blade tips and exhaust system losses; these losses are of approximately equal proportions. The total losses result in anoverall efficiency of approximately 92 percent.从燃气流向涡轮的能量转移6 有第一段的描述我们可知，涡轮的工作在与然气流和涡轮之间的能量转移。

But there is also a deeper level to our uneasiness. For we grew up to think with Emerson that America is the country of young men. That was part of our heritage of optimism, of our faith in progress. A society that believed in inevitable improvement that judged tomorrow always better than yesterday, necessarily ascribed a special virtue to youth, less constricted by the errors of the past, more responsive to the opportunities of the future. It was proper that the young should rise up against the old; experience would always justify the rebellion In fact, the old rather expected that this would happen and could enjoy the burden of progress. Perhaps we in our group resent this present generation so much because we fear they are stealing from us the leisure of our conservatism. How can we sit by if they too accept the status quo ante(原状) and if no one pushes forward?1. The reader may most safely conclude that the authorA. was a contemporary of Emerson.B. rebelled against authority when he was young.C. looks forward to having more leisure.D. considers himself a member of the older genera-tion.2. The main idea of the passage isA. a review of the American heritage of optimism.B. a praise of the young people's virtue.C. a deep concern about whether the young people will keep up the traditional pioneering spiritD. a defense of conservatism3. According to the passage, Emerson was esteemed(尊敬) for hisA. love of America as a country for younger generation.B. justification of the errors made by the old generation in the past.C. upholding of American heritage.D. confidence in the following generations on whom the future of the U.S relies.4. The young people, according to the passage, are now actuallyA. rising up against the oldB. by pushing forward to a brighter tomorrow.C. responsive to the opportunities of the future.D. satisfied with the present state of affairs.5.
