Write your answers on your answer sheet.Passage OneAt some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you don't act on your impulse, but let it pass instead. You know that to commit the action is wrong in some way and that other people will not accept your behavior.Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject.One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is a topic that Americans talk about constantly. It's not taboo to talk about fat; it's taboo to be fat. The "in" look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their image as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In an image-conscious society like the U. S. , thin is "in", fat is "out".It's not surprising, then, that millions of Americans have become obsessed with staying slim and "in shape". The pursuit of a youthful physical appearance is not, however, the sole reason for America's obsession with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do by hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people's bodies can easily become weak and vulnerable to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising every day. 1. From the passage we can infer taboo is ______.A. a strong desire to do something strange or terribleB. a crime committed on impulseC. behavior considered unacceptable in society's eyesD. an unfavorable impression left on other people2. Based on the ideas presented in the passage we can conclude "being fat"_______.A. will always remain a tabooB. is not considered a taboo by most peopleC. has long been a tabooD. may no longer be a taboo some day3. The topic of fat is _______ many other taboo subjects.A. the same asB. different fromC. more popular thanD. less often talked about than4. In the U. S., thin is "in", fat is "out", this means _______.A. thin is "inside", fat is "outside"B. thin is "diligent", fat is "lazy"C. thin is "youthful", fat is "spiritless"D. thin is "fashionable", fat is "unfashionable"5. The main reason the passage gives for why so many Americans are exercising regularly is _______.A. their changed life-styleB. their eagerness to stay thin and youthfulC. their appreciation of the importance of exerciseD. the encouragement they have received from their companiesPassage TwoOpinion polls are now beginning to show that, whoever is to blame and whatever happens from now on, high unemployment is probably here to stay. This means we shall have to find ways of sharing the available employment more widely.But we need to go further. We must ask some fundamental questions about the future work. Should we continue to treat employment as the norm? Should we not rather encourage many ways for self-respecting people to work? Should we not create conditions in which many of us can work for ourselves, rather than for an employer? Should we not aim to revive the household and the neighborhood, as well as the factory and the office, as centers of production and work?The industrial age has been the only period of human history in which most people’s work has taken the form of jobs. The industrial age may now be coming to an end, and someof the changes in work patterns which it brought may have to be reversed. This seems a daunting thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history shows, has not meant economic freedom.Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by depriving them of the use of the land, and thus of the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people’s homes. Later, as transport improved first by rail and then by road, people commuted longer distances to their places of employment until, eventually, many people’s work lost all connection with their home lives and the places in which they live.Meanwhile, employment put women at a disadvantage. In preindustrial times, men and women had shared the productive work of the household and village community. Now it became customary for the husband to go out to paid employment, leaving the unpaid work of the home and families to his wife. Tax and benefit regulations still assume this norm today, and restrict more flexible sharing of work roles between the sexes.It was not only women whose work status suffered. As employment became the dominant form of work, young people and old people were excluded—a problem now, as more teenagers become frustrated at school and more retired people want to live active lives.All this may now have to change.The time has certainly come to switch some effort and resources away from the idealist goal creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs.6. What is the main idea of the passage?A. Employment became widespread in the 17th and 18th centuries.B. Unemployment will remain a major problem for industrialized nations.C. The industrial age may now be coming to an end.D. Some efforts and resources should be devoted to helping more people cope with theproblem of unemployment.7. Which of the following was NOT mentioned as a factor contributing to the spread of employment?A. The enclosures of the 17th and 18th centuries.B. The development of factories.C. Relief from housework on the part of women.D. Development of modern means of transportation.8. It can be inferred from the passage that____.A. most people who have been polled believe that the problem of unemployment maynot be solved within a short period of timeB. many farmers lost their land when new railways and factories were being constructedC. in preindustrial societies housework and community service were mainly carried outby womenD. some of the changes in work pattern that the industrial age brought have beenreversed9. What does the word “daunting” in the third paragraph mean?A. ShockingB. InterestingC. ConfusingD. Stimulating10. Which of the following is NOT suggested as a possible means to cope with the currentsituation?A. Create situations in which people work for themselves.B. Treat employment as the norm.C. Endeavor to revive the household and the neighborhood as centers of production.D. Encourage people to work in circumstances other than normal working conditions. Passage ThreeNo one should be forced to wear a uniform under any circumstances. Uniforms are demanding to the human spirit and totally unnecessary in a democratic society. Uniforms tell the world that the person who wears one has no value as an individual but only lives to function as a part of a whole.The individual in a uniform loses all self-worth. There are those who say that wearing a uniform gives a person a sense of identification with a larger, more important concept. What could be more important than the individual himself? If an organization is so weak that it must rely on cloth and buttons to inspire its members, that organization has no right to continue its existence. Others say that the practice of making persons wear uniforms, say in a school, eliminates all envy and competition in the matter of dress, such that a poor person who cannot afford good quality clothing is not to be belittled by a wealthy person who wears expensive quality clothing. Those persons conveniently ignore such critical concepts as freedom of choice, motivation, and individuality. If all persons were to wear the same clothing, why would anyone strive to be better? It is only a short step from forcing everyone to drive the same car, have the same type of food. When this happens, all incentive to improve one’s life is removed. Why would parents bother to work hard so that their children could have a better life than they had when they know that their children are going to be forced to have exactly the same life that they had?Uniforms also hurt the economy. Right now, billions of dollars are spent on the fashion industry yearly. Thousands of persons are employed in designing, creating and marketing different types of clothing. If everyone were forced to wear uniforms, artistic personnel would be unnecessary. Sales person would be superfluous as well; why bother to sell the only items that are available? The wearing of uniforms would destroy the fashion industry, which in turn would have a ripple effect on such industries as advertising and promotion. Without advertising, newspapers, magazines, and television would not be able to remain in business. The entire information and entertainment industry would collapse.11.The author’s primary purpose in writing this passage is to __________ .A. plead for the abolition of uniformsB. show that uniforms are not possible in a democratic societyC. advocate stronger government controls on the wearing of uniformsD. convince the reader that uniforms have more disadvantages than advantages12.Why does the author discuss forcing everyone to buy the same car or eat the same food?A. To show that freedom of choice is absolute.B. To show that the government has interfered too much in the lives of individual.C. To suggest what would happen if uniforms became compulsory.D. To predict the way the society will be in the next few generations.13.Which of the following statements is the opinion of those who support uniforms?A. The person who wears a uniform has no self-worth.B. Wearing a uniform gives a person a sense of identification with a larger concept.C. Uniforms will hurt the entire information and entertainment industry.D. Envy and competition are incentive to improve one’s life.14.The word “superfluous” (Line 4, Para. 3) most probably means __________ .A. surplusB. indispensableC. availableD. supplementary15.The next paragraph in this passage might discuss __________ .A. the positive effects of wearing uniformsB. more negative effects of wearing uniformsC. an alternative to wearing uniformsD. The legal rights of those not wishing to wear uniformsPassage FourWhy the inductive and mathematical sciences, after their first rapid development at the culmination of Greek civilization, advanced so slowly for two thousand years—and why in the following two hundred years a knowledge of natural and mathematical science has accumulated, which so vastly exceeds all that was previously known that these sciences may be justly regarded as the products of our own times—are questions which have interested the modern philosopher no less than the objects with which these sciences are more immediately conversant. Was it the employment of a new method of research, or in the exercise of greater virtue in the use of the old methods, that this singular modern phenomenon had its origin? Was the long period one of arrested development, and is the modern era one of normal growth? Or should we ascribe the characteristics of both periods to so-called historical accidents—to the influence of conjunctions in circumstances of which no explanation is possible, save in the omnipotence and wisdom of a guiding Providence?The explanation which has become commonplace, that the ancients employed deduction chiefly in their scientific inquiries, while the moderns employ induction, proves to be too narrow, and fails upon close examination to point with sufficient distinctness the contrast that is evident between ancient and modern scientific doctrines and inquiries. For all knowledge is founded on observation, and proceeds from this by analysis, by synthesis and analysis, by induction and deduction, and if possible by verification, or by new appeals to observation under the guidance of deduction—by steps which are indeed correlative parts of one method; and the ancient sciences afford examples of every one of these methods, or parts of one method, which have been generalized from the examples of science.A failure to employ or to employ adequately any one of these partial methods, an imperfection in the arts and resources of observation and experiment, carelessness in observation, neglect of relevant facts, by appeal to experiment and observation—these are the faults which cause all failures to ascertain truth, whether among the ancients or the moderns; but this statement does not explain why the modern is possessed of a greater virtue, and by what means he attained his superiority. Much less does it explain the sudden growth of science in recent times.The attempt to discover the explanation of this phenomenon in the antithesis of “facts” and “theories” or “facts” and “ideas”—in the neglect among the ancients of the former, and their too exclusive attention to the latter—proves also to be too narrow, as well as open to the charge of vagueness. For in the first place, the antithesis is not complete. Facts and theories are not coordinate species. Theories, if true, are facts—a particular class of facts indeed, generally complex, and if a logical connection subsists between their constituents, have all the positive attributes of theories.Nevertheless, this distinction, however inadequate it may be to explain the source of true method in science, is well founded, and connotes an important character in true method. A fact is a proposition of simple. A theory, on the other hand, if true has all the characteristics of a fact, except that its verification is possible only by indirect, remote, and difficult means. To convert theories into facts is to add simple verification, and the theory thus acquires the full characteristics of a fact.16. The title that best expresses the ideas of this passage isA. Philosophy of mathematics.B. The Recent Growth in Science.C. The Verification of Facts.D. Methods of Scientific Inquiry.17. According to the author, one possible reason for the growth of science during the days ofthe ancient Greeks and in modern times is_________________.A. the similarity between the two periodsB. that it was an act of GodC. that both tried to develop the inductive methodD. due to the decline of the deductive method18. The difference between “fact” and “theory”A. is that the latter needs confirmation.B. rests on the simplicity of the former.C. is the difference between the modern scientists and the ancient Greeks.D. helps us to understand the deductive method.19. According to the author, mathematics is __________________.A. an inductive scienceB. in need of simple verificationC. a deductive scienceD. based on fact and theory20. The statement “Theories are facts” may be called_______________.A. a metaphorB. a paradoxC. an appraisal of the inductive and deductive methodsD. a punPart II Translation from English to Chinese (20 points)Directions:Put the following passage into Chinese. Write your answer on your answer sheet.Why is cross-cultural knowledge and understanding so important? The American statesman and inventor Benjamin Franklin wrote that time is money. Globe-trotting businesspeople would add that being aware of cultural differences and sensitivities is money, too. Failing to grasp the subtleties that lie beyond such public cultural displays like greeting rituals and seating arrangements can make the difference between a truly successful international business transaction and one that fails to connect. Culture affects the most basic forms of personal and business interaction from decision making to management style. National culture, in turn, determines corporate culture, affecting a firm’s internal structure, its marketing behavior and its view of foreign business partners and contracts. The business world is littered with “international” projects that failed to overcome cultural barriers. If you have doubts that cultural insensitivity can translate into business problems on a megascale. Part III Translation from Chinese into English (20 points)Directions: Put the following Chinese into English. Write your answer on your answer sheet.掌握英语不仅可以改进你的思维方式，它还给你信心，令你自信，带给你鲜明的个性，使你更受欢迎。

Our team is to design a smart balancing vehicle with a camera. The principle of our balancing vehicle is a kind of symmetrical layout, using accelerometers and gyroscopes in collabo ration with each other before and after the tilt angle and angular velo city detection , while taking advantage of the sliding rheostat for test ing self-balancing vehicle steering control lever tilt angle , and the informatio n output to the microcontroller, by appropriate control algorithm to c alculate the amount of control , drive motor , and completed self-balancing vehicle forward, backward and turning such action . Ther e is a camera at the top of the balancing vehicle, which can observe the surrounding environment ,so it can avoid the obstacles ahead and choose the best way by analysis of image ahead.(III) BackgroundAt present, balancing vehicle has widely spread to people's life bothin domestic and foreign and development in the field of publictransport. At the 2008 Olympics, the segway electric smart balancingcar won the attention of many people. But this propose introducesthe automatic obstacle avoidance based on vision sensors and imageanalysis of the balancing vehicle is more similar to a kind ofintelligent robots. Although the obstacle avoidance of intelligentvehicle research at home and abroad are early, but mainly based oninfrared sensor, detection radar and other navigation systems withcomplex system , big volume and high cost. Vision as an importantmeans of robots for environment information, to the information characteristics of the mobile robot navigation is of importanttheoretical significance and practical application value. Compared toother active measures, the information by stereo vision is fast andaccurate, commonly used to detect suspicious barrier height anddistance.(IV) MethodologyWe are ready to develop the smart balancing vehicle which is based onmature platform, integrated vision sensor. Namely separating obstaclesfrom the back-ground by typical image processing method, andperforming the stereo matching of the extracted contour features in combination with the binocular vision calibration results to get the spatialpoint of 3D reconstruction. The obstacle avoidance rule and controlleraccording to the fuzzy principle were designed to avoid collision and by pass the enroute obstacles. The whole running performance of smart balancing vehicle firstly depends on the power supply and motor driver module. The vehicle 's drive not only requires the motor drive system torque weight than high, wide speed range, high reliability, and because the torque - speed characteristic easily affected by power, which requires the driver has the efficient area as wide as possible.(V)Potential conclusionIf each part of our plan can be successfully finished, we expect that we can product the smart balancing vehicle in 6 months as planned(VI)Schedule▪Prepare proposal and theoretical knowledge by 1 November ▪The overall system design by 15 November▪Select and lap hardware circuit by 15 January▪Algorithm design and programming by 15 February▪Test the motor on March▪Complete the balancing vehicle on May(VII)References[1] LI Y.

44 Quality in Manufacturing
• The lesson learned by manufacturing in the 1970s is that technology alone cannot improve business performance, and a new emphasis on quality and development of the workforce was required. The move to quality has two major elements： a new philosophy on how the business must function and the use of quality tools to achieve the desired results．This broader view of quality is included in a process called total quality management (TQM). TQM has two components: principles and tools. The principles allow an organization to overcome the traditional barriers that prevented the management group from utilizing the potential, skills, and knowledge of every employee．The tools permit quantitative and qualitative measurement of the system to determine how well the process is meeting organizational goals.

44 Quality in Manufacturing
44 Quality in Manufacturing
• The definition of TQM has three dominant themes: (1) participative management for everyone in the enterprise, (2) implementation of a successful continuous improvement process, and (3) efficient use of multifunctional teams. The six important principles that must be considered in a TQM implementation include (1) a focus on customer needs and satisfaction; (2) a focus on the process used to produce a product as opposed to a result or product focus; (3) a focus on the prevention of problems in areas such as quality, production，machine operation，and engineering design changes; (4) a focus on using the brain power of every employee in the organization; (5) a focus on basing decisions on facts about manufacturing and design without blame when problems occur；and (6) a focus on developing an enterprise where communication channels are always open so that product data and process information flow freely among all levels and all employees.
