- Passage 2 Question 6 to 10 are based on the fowling passage: Today’s students have grown up hearing more about Bill Gates than F.D.R.,and they live in a world where amazing innovations(革新)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 Harvard and they were entering high school. Having grown up digital(数字的),they are impatient to get on with life. The easiest way to find kids like these is to check in on entrepreneurship(企业家才能)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 50,000 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 school,and even in the liberal arts. “Our interest is 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 special laboratory,create wearable technologies. (78)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” What does Daniel S.Grennberg think of entrepreneurship education?

- Passage 1 Questions 1 to 5 are based on the following passage: The reflective towers of New York City, which is on the Atlantic migrating(迁徙的)route ,can be deadly for birds. “We live in an age of glass,” said Ms.Laurel, an architect.(76)“It can be a perfect mirror in certain lights,and the larger the glass,the more dangerous it is.” About 90,000 birds are killed by flying into building in the city each year. Often,they strike the lower levels of glass towers after searching for food in nearby parks. Such crashes are the second-leading cause of death for migrating birds,after habitat(栖息地)loss,with an estimated number of death ranging up to a billion a year. (77)As glass office and apartment towers have increased in the last decade,so,too,have calls to make them less deadly to birds. San Francisco adopted bird-safety standard for new building in July. The United States Green Building Council,a nonprofit industry group that encourages the creation of environmentally conscious buildings,will introduce a bird-safety credit this as part of its environmental certification process. There are no easy fixes,however. A few researchers are exploring glass designs that use ultraviolet(紫外线的)signals,but they are still in their infancy. Covers,dot patterns,shades and net are the main options available. Often,only one section of a building needs to be changed. “You don’t necessarily have to treat every window,” Ms.Laurel said. “It would be too expensive to do the whole building.” The Jacob Convention Center, which has been undergoing alterations,the most recent building to voluntarily correct the problem of bird crashes. The architects used less reflective glass and dot patterns. What is the number one cause of death for migrating birds?

- Passage 3 Question 11 to 15 are based on the following passage: Regret is as common an emotion as love or 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 surveys,Neal Rose,a psychologist and professor of marketing at the School of Management at Northwestern Universtiy,and Mike Morrison,a doctoral candidate in psychology at University of Illinois,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 something they did or didn’t do,and whether it was something that could still be fixed. The most commonly mentioned regret involved romance (浪漫的事)(18%)——lost loves or unfulfilled relationships. Family regrets came in second (16%),whit people still feeling badly about being unkind to their brothers or sisters in childhood. Other frequently reported regrets involved career (13%) ,education (12%),money(10%) and parenting(9%)。 Rose and Morrison’s study,which is to be published in social psychological and personality science,is significant in that it surveyed a wide range of the American public,including people of all ages and socio-economic and educational backgrounds. Previous studies on regret have focused largely on college students,who predictably tend to have education-focused regrets,like wishing they had studied harder or a different major. The new survey shows that in the larger population,a person’s major. The new survey shows that in the larger population,a person’s “life circumstances—accomplishments,shortcomings ,situation in life—inject considerable fuel into the fires of regret,”the authors write. (79)People with less education,for instance were more likely to report education regret. People with higher levels of education had the most career regrets. And those with no romantic partner tended to hold regrets regarding love. Broken down(分解、细分)by sex, more women(44%) than men (19%) had regrets about love and family——not surprising,since women “value social relationships more than men,” the authors write. In contrast ,men (34%)were more likely than women (27%)to mention work-related regrets,wishing they’d chosen a different career path,for instance ,or followed their passion.(80)Many participants also reported wishing they had worked less to spend more time with their children. There was an even split between regrets about inaction (not doing something)and action (do something you wish you didn’t).But,like previous studies,the current research found that some regrets are more likely than others to persist over time:people tend to hang on longer to the regret of inaction;meanwhile,regrets of action tend to be more recent. According to the passage ,college student participants mainly had regrets about their ______.

- Passage 1 Questions 1 to 5 are based on the following passage: The reflective towers of New York City, which is on the Atlantic migrating(迁徙的)route ,can be deadly for birds. “We live in an age of glass,” said Ms.Laurel, an architect.(76)“It can be a perfect mirror in certain lights,and the larger the glass,the more dangerous it is.” About 90,000 birds are killed by flying into building in the city each year. Often,they strike the lower levels of glass towers after searching for food in nearby parks. Such crashes are the second-leading cause of death for migrating birds,after habitat(栖息地)loss,with an estimated number of death ranging up to a billion a year. (77)As glass office and apartment towers have increased in the last decade,so,too,have calls to make them less deadly to birds. San Francisco adopted bird-safety standard for new building in July. The United States Green Building Council,a nonprofit industry group that encourages the creation of environmentally conscious buildings,will introduce a bird-safety credit this as part of its environmental certification process. There are no easy fixes,however. A few researchers are exploring glass designs that use ultraviolet(紫外线的)signals,but they are still in their infancy. Covers,dot patterns,shades and net are the main options available. Often,only one section of a building needs to be changed. “You don’t necessarily have to treat every window,” Ms.Laurel said. “It would be too expensive to do the whole building.” The Jacob Convention Center, which has been undergoing alterations,the most recent building to voluntarily correct the problem of bird crashes. The architects used less reflective glass and dot patterns. What is the main idea of the passage?

- Radiocarbon Dating Nowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), or carbon-14, dating. One key to understanding how and by something happened is to discover when it happened. Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at he University of Chicago. An atom of ordinary carbon, called carbon-12, has six protons(质子) and six neutrons (中子) in its nucleus(原子核). Carbon-14, or C-14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of he extra neutrons and energy from the nucleus. In Libby’s radiocarbon dating technique, the weak radioactive emissions (放射) from this decay process are counted by instruments such as a radiation detector and counter. The decay rate is used to determine the proportion of C-14 atoms in the sample being dated. Carbon-14 is produced in the Earth’s atmosphere when nitrogen (氮)-14, or N-14,interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the mount of nitrogen in the atmosphere has remained constant. Consequently, C-14 formation is thought to occur at a constant rate. Now the ratio of C-14 to other carbon toms in the atmosphere is known. Most scientists agree that this ratio is useful for dating items back to at least 50,000 years. All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C-14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, and the C-14 already present begins to decay. Over time the amount of C-14 in the material decreases, and the ratio of C-14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C-14 atoms in a sample, the older that sample is. The radiocarbon dating technique is only about 40 years old
