Reading Comprehension (20 points)Passage OneQuestions 31 to 35 are based on the following passage.The iMOVE database (数据库) is a foreign-language information platform for persons interested in job opportunities offered by German companies. The information can be obtained in seven languages, German, English, French, Spanish, Chinese, Russian and Arabic.All programs in the area of professional training are carried out by German training providers. All these programs have a clear content to meet your special needs.Programs which take place in Germany are carried out in English. Many of the German training providers have started their training activities towards the international market. Therefore, they also offer courses abroad. These courses aretaught in English or the language of the target country. Providers will be .glad to supply you with additional information on these courses. You can contact the providers directly to find out more about a program and the training provider.To guarantee high standards in the database, iMOVE has developed quality standards for training providers and their service. All of the training facilities in the iMOVE database have to follow these quality criteria (标准). All training providers who publish their international training programs in the iMOVE database have recognized our General Terms and Conditions.31. The iMOVE database is intended for persons who ______.A. seek a job as a language translatorB. are interested in the German languageC. want to be employed by German companiesD. wish to work for professional training providers32. The iMOVE programs are carried out by ______.A. language training centersB. German training providersC. special service developersD. overseas employment advisers33. The training programs held in Germany are taught in ______.A. GermanB. EnglishC. FrenchD. Chinese34. Which of the following measure has iMOVE taken to guarantee its highstandards?A.

The purpose of the passage is to ______.A. advertise the iMOVE databaseB. make German companies more popularC. hire overseas employees to work in GermanyD. encourage people to learn more foreign languagesPassage TwoQuestions 36 to 40 are based on the following passage.In the United States, a person can take credit only for what he has accomplished by himself. Americans get no credit whatever for having been born into a rich or privileged family. (In the United States, that would be considered “an accident of birth.”) Americans pride themselves in having been born poor and, through their own hard work, having climbed the difficult ladder of success to whatever level they have achieved---all by themselves. The American social system has, of course, made it possible for Americans to move, relatively easily, up the social ladder, whereas this is impossible to do in many other countries. The “self-made man or woman” is still very much the ideal in present-day America.Americans believe that competition brings out the best in any individual. They claim that it challenges or forces each person to produce the very best that is humanly possible. Consequently, the foreign visitor will see competition being fostered in the American home and in the American classroom, even at the youngest age levels. You may find the value placed on competition disagreeable, especially, if you come from a society that promotes cooperation rather than competition among individuals. But Americans teaching in Third World countries find the lack of competitiveness in a classroom situation equally distressing(令人苦恼的). They soon learnt that what they had thought to be one of the universal human characteristics represented only a peculiarly American (or Western) value.Americans, valuing competition, have devised an economic system to go with it –free enterprise (自由企业制). Americans feel very strongly that a highly competitionwill progress most rapidly. If you look for it, you will see evidence in all areas – in all fields as diverse (不同的) as medicine, the arts, education, and sports –that free enterprise is the approach most often preferred in America.36. What does the author mean by saying “The …self-made man or woman‟ is still verymuch the ideal in present-day America”? ______A. Americans no longer respect those who are born rich as they used to.B. Americans still respect those who have climbed up the social ladder throughhard work.C. Americans think that an ideal man or woman should be born poor.D. Americans think that only the self-made man or woman is worthy of respect.37. What does the author think of the American social system ? ______A. It is a system that does not favor those who are born rich.B. It is a system that makes social climbing very difficult, if not impossible.C. It makes it comparatively easy for the poor to move up the social ladder.D. It is the best system possible in the world.38. Americans teaching in Third World countries found that ______.A. competition is a unique American (or Western) valueB. competition must be fostered in the classroom for success in businessC. cooperation is more important than competition in bringing about progressD. competition is one of the universal human characteristics39. We can infer from the passage that free enterprise is ______.A. an economic system allowing free competition among businessesB. a belief that competition brings out the best in any individualC. an attitude that values competition rather than cooperationD. a theory that advocates competition as the source of all progress40. Americans would most likely frown at you if you ______.A. tell them you were born poor and had to work with your hands.B. complain that you were born poor and had had no opportunitiesC. go around telling people that your father is a self-made manD. tell them that their social system is not necessarily the bestPart IV Translation (10 points)41.The noise in the streets________________________________________.(使我不能专心读书)42.This company has spent millions of dollars on advertising, tryingto_______________________________________________________________.
