Each passage is followed by some questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. You should decide on the best choice.Today's students have grown up hearing more about Bill Gates than F. D. R., and they live in a world where amazing innovations are common. The current 18-year-olds, after all, were 8 when Google was founded by two students at Stanford; Mark Zuckerberg founded Facebook in 2004 while he was at Harvard and they were entering high school. Having grown up digital, they are impatient to get on with life.The easiest way to foster kids like these is to check in on entrepreneurship education, in which colleges and universities try to prepare their students to recognize opportunities and seize them.A report published last year by the Kauffman Foundation, which finances programs to promote innovation on campuses, noted that more than 5,000 entrepreneurship programs are offered on two- and four-year campuses-up from just 250 courses in 1985. Lesa Mitchell, a Kauffman vice president, says that the foundation is extending the reach of its academic influence, which used to be found only in business schools. Now, the concept of entrepreneurship is blooming in engineering programs and medical schools, and even in the liberal arts. “Our interest is in all the programs,” she says.“We need to spread out from the business school.”Either as class projects or on their own, students in a variety of majors are coming up with ideas, writing business plans and seeing them through to prototype and, often, market. In their spare time, students in agricultural economics at Purdue invent new uses for bean; industrial design majors at Syracuse, in a special laboratory, create wearable technologies.The entrepreneurship movement has its critics' especially among those who see college as a time for extensive academic exploration. “I just don't think that entrepreneurship ranks so high in terms of national: need,”says Daniel S. Greenberg, author of Science for Sale: The Perils, Rewards and Delusions of Campus Capitalism.Leonard A. Schlesinger, Babson College's president, says that the question of whether innovation can really be taught is“an age-old argument.”1. When Google and Facebook were established, the founders were still_______.A、in high schoolB、in the armyC、in primary schoolD、at college答案：D2. According to the passage, what is the main purpose of entrepreneurship education? _______A、To prepare students for future academic life.B、To prepare students to find opportunities and seize them.C、To prepare students for overseas career.D、To prepare students to develop interpersonal skills.答案：B3. The word “prototype” in the fourth paragraph is most likely to mean_______A、modelB、strategyC、methodD、stage答案：A4. What does Daniel S. Greenberg think of entrepreneurship education? _______A、Entrepreneurship, or at least certain elements of it, can be taught.B、An entrepreneurship program can help students find what they really like and entrepreneurship isn't all about business.C、Entrepreneurship should be spread across different fields.D、Colleges shouldn't put too much emphasis on entrepreneurship programs.答案：DPart III. Translate English into Chinese.Regret is as common an emotion as love for fear, and it can be nearly as powerful. So, in a new paper, two researchers set about trying to find out what the typical American regrets most. In telephone survey, Neal Rosese, a psychologist and professor of marketing at the School of management at Northwestern University asked 370 Americans, aged 19 to 103, to talk about their most notable regret. Participants were asked what the regret was, when it happened, whether it was a result of sth they did or didn’t do, and whether it was sth that could still be fixed.主观题无标准答案。

He believed that language is a system of sings. To communicate ideas，signs must be part of a system of signs，called conventions. He held that the sign is the union of the signifier and the signified. He made clear the object of study for linguistics as a science. His ideas on the arbitrary nature of sign，on the relational nature of linguistic units，on the distinction of langue and parole and of synchronic and diachronic linguistics，etc. pushed linguistics into a brand new stage.9) （3.5 points）Conceptual meaning；connotative meaning；social meaning；affective meaning；reflected meaning；collocative meaning；thematic meaning；10) （4 points）Linguistics can contribute to the research in language learning by providing more accurate information about what language is in the first place. Language learning researchers are concerned with how teachers should teach and learner should learn. But the questions of “what to teach” and “what to learn” should be answered first. Linguistics certainly has an important role in answering these questions. Besides，applying linguisticanalysis to the description of the language produced by language learners can also facilitate out understanding of how learners actually learn language.。
