Read each passage carefully, and then do the questions that follow. Choose the best answer from the four choices given and mark the corresponding letter with a single bar across the square brackets on your machine-scoring Answer Sheet.Passage OneAs many people hit middle age, they often start to notice that their memory and mental clarity are not what they used to be. We suddenly can't remember where we put the keys just a moment ago or an old acquaintance’s name. As the brain fades, we refer to these occurrences as “senior moments.” While seemingly innocent, this loss of mental focus can potentially have a detrimental impact on our professional, social, and personal well-being.Neuroscientists are increasingly showing that there’s actually a lot that can be done. It turns out that the brain needs exercise in much the same way our muscles do, and the right mental workouts can significantly improve our basic cognitive functions. Thinking is essentially a process of making neural connections in the brain. Because these connections are made through effort and practice, scientists believe that intelligence can expand and fluctuate according to mental effort.A new company has taken it a step further and developed the first “brain training program”, called Lumosity, to actually help people improve and regain their mental sharpness. Lumosity is far more than an online place to exercise your mental skills. That’s because they have integrated these exercises into a Web-based program that allows you to systematically improve your memory and attention skills. The program keeps track of your progress and provides detailed feedback on your performance and improvement. Most importantly, it constantly modifies and enhances the games you play to build on the strengths you are developing - much like an effective exercise routine requires you to increase resistance and vary your muscle use.Apparently it works. In randomized, controlled clinical trials Lumosity was shown to significantly improve basic cognitive functions. One study showed students improved their scores on math tests by 34 percent after using Lumosity for six weeks. The company says its users have reported clearer and quicker thinking, improved memory, increased alertness and awareness, elevated mood, and better concentration at work or while driving.While many of the games at Lumosity are free, a modest subscription fee is required to use the full program over the long term. However, Lumosity is currently offering a free trial of their program to new users so that you can see how well it works before you decide to subscribe. The company believes the results will speak for themselves.51.What can we learn about “senior moments”?A. They are nothing to be worried about.B. They happen to each middle-aged person.C. They mostly happen to the elders.D. They are signs of declining memory.52. Neuroscientists are beginning to find that ________.A. cognitive functions can be improved by mental effortB. intelligence varies with the amount of physical exerciseC. “senior moments” are quite useful at workD. our brain and muscles should be trained differently53. From Paragraph 3, it can be concluded that Lumosity ________.A. is just an online place to exercise your mental skillsB. requires the users to keep doing the same gamesC. is a set of exercises intended for the mentally-retardedD. can help users make improvement in the brain54. Clinical trials have proved that Lumosity ________.A. is better than reportedB. is highly effective and beneficialC. should be under strict controlD. leaves much to be desired55. Which of the following statements is true about Lumosity?A. Access to these games is quite expensive.B. Chronic users have to pay for the access to the games.C. All the games at Lumosity are free of charge.D. Access to the games is limited to subscribers.56. The main purpose in writing this passage is to ________.A. present the new findings of neuroscientistsB. remind the middle-aged to take physical exerciseC. describe how Lumosity came into beingD. introduce how braining training makes you smarterPassage TwoAccording to psychology pr ofessor Carol Dweck of Stanford University, “Praising children for being smart can backfire.”If this doesn't get the attention of Millennium parents, I’m not sure what will. It is my observation that so many parents today believe that if their child appears to be the least bit “advanced” for his age, he’s destined to be the next Albert Einstein, Tiger Woods, or Bill Gates.It’s human nature for mom and dad to show much admiration for their child and dish out praise for accomplishments achieved. The problem is, according to this study, parents may not be doing the best thing by praising their child for his intelligence.Dweck’s research involved junior high students in New York and concluded that “classroom performance improved when her study subjects believed the brain is like a muscle that can grow.”Students who “focused on the learning process (effort, concentration or strategies used) asked for feedback and did better in all subjects.” Feedback such as, ‘You did well because you worked so hard’ or ‘You used so many descriptive words to make this story interesting’ can encourage children to try new things, as they are being rewarded for their effort. When the ‘time and effort’ strategy is being positively reinforced, the child will probably use the same strategy next time they are learning something. Over time new strategies can be introduced, so the child’s repertoire of strategies is broadened.Dweck goes on to say that “they (students who improved) performed better because their success was being measured by effort, not by test scores or grades.” Parents should praise effort, not just results. Children who received praise about their innate abilities (talents or strengths) had less chance of trying new things and became anxious and under performed as things became more difficult. That is one of the greatest dangers to continually praising children for whatever they do in order to falsely raise a child’s self-esteem.What are mom and dad to do? Offer genuine praise and encouragement for effort and successes, butbalance this with setting appropriate expectations and following up with consequences when the child falls short due to laziness. Don’t make excuses. Your child will better face the challenges life has to offer in the future when you as a parent recognize the efforts he is making today.57. The underlined word “backfire” in the first paragraph probably means ________.A. create some miraclesB. produce an undesirable resultC. be negligible to some extentD. be motivating and inspiring58. Which of the following can be considered proper feedback?A. You did really well on this spelling test, you must have spent hours practising your words.B. Oh, honey, you’re so smart—that failing grade won’t matter anyway.C. This is a wonderful painting. What a great artist you are!D. You did really well on this spelling test, you are very clever.59. A child who is praised for his effort and strategy is likely to ________.A. have his learning strategies increasedB. feel inferior to the smart childrenC. have falsely high self-esteemD. expect more praise and encouragement60. Praising a child for his talent may _______.A. encourage him to try new thingsB. motivate him to greater effortsC. leave him less prepared for challengesD. put his life at risk in case of failure61. The author’s advice to parents is________.A. to expose the child to greater challengesB. not to expect too much of a childC. to forbid the child to make any excusesD. to combine praise with constructive criticism62. Which of the following can be a proper title for this passage?A. Never Praise Your Child for Any of His AchievementsB. Praise Your Child, But Not for Being SmartC. How to Reward a Child for His EffortD. Praise –a Must for the Child’s FuturePassage ThreeAs a new matchmaker, internet dating sites promise two cutting edges: a vastly greater choice of potential partners and scientifically proven way of matching suitable people together.The greater choice is unarguable. But does it lead to better outcomes? And do the “scientifically tested methods” actually work? These are the questions asked by a team of psychologists led by Eli Finkel.The researchers’ first observation is how any of the muc h-boasted partner-matching methods actually works. Many firms preserve their intellectual property as trade secrets, and there is no reason why internet dating sites should not be among them. But this renders claims of effectiveness impossible to test objectively. There is thus no independent scientific evidence that any of these methods does enhance the chance of their hitting it off when they meet.It is possible to test the value of a claim that they match people with compatible personality traits. However, Dr Dyrenforth asked more than 20,000 people about their relationships and assessed their personalities. Members of couples with similar personalities were indeed happier than those without. But the difference was just 0.5%.Surely, the chances of finding that magic other are increased by the second thing internet dating brings: a multitude of choice. But here, too, things are not as simple as they might seem.An assumption behind all consumer decisions is that what people think they want is what they actually need. And the data suggest people are not good at knowing what they want. One of Dr Finkel’s own studies showed that when they are engaged in speed dating, people’s stated preferences at the beginning of the process do not well match the characters of the individuals they actually like. When faced with abundant choices, people pay less attention to characteristics that require thinking and conversation to evaluate and more to matters physical. Choice, in other words, dulls the critical faculties.Fi nkel’s conclusion is that love is as hard to find on the internet as elsewhere. You may be just as likely to luck out in the local café, or by acting on the impulse to stop and talk to that stranger on the street whose glance you caught, as you are by clicking away with a mouse and hoping that, one day, Cupid’s arrow will strike.63. The effectiveness of the dating sites is difficult to verify scientifically because they ________.A. keep their intellectual property secretB. have two cutting edgesC. adopt strange matching methodsD. are good at deception as evidenced64. The expression “hit it off” in Paragraph 3 probably means _______.A. say goodbyeB. get along wellC. get hurtD. dislike each other65. Dr. Dyrenforth found that couples with different personalities ________.A. were much less happy than those with similar personalitiesB. were more likely to divorce than those with similar personalitiesC. were almost as happy as those with similar personalitiesD. were much happier than those with similar personalities66. According to Paragraph 6, the abundance of choices offered by the dating sites ________.A. can increase the chance of finding ideal partnersB. helps people to become better aware of what they wantC. diverts attention from other mental qualitiesD. leads to exclusive concern with one’s appearance67. Finkel’s conclusion is that _______.A. it is impossible to find true love on the Internet wherever you areB. you are as likely to find love through chance encounters as via the InternetC. you are more likely to find love through these online dating sitesD. you can find love more easily by talking to a stranger on the street68. The researchers’ attitude towards thes e Internet dating sites is ________.A. suspicionB. confidenceC. objectionD. recommendationPassage FourMany countries have made it illegal to talk into a hand-held mobile phone while driving. But the latest research provides further confir mation that the danger lies less in what a motorist’s hands do when he takes a call than in what the conversation does to his brain. Even using a “hands-free” device can impair a driver’s attention to an alarming extent.Melina Kunar of the University of Warwick and Todd Horowitz of the Harvard Medical School ran a series of experiments in which two groups of volunteers had to pay attention and respond to a series of moving tasks on a computer screen that were reckoned equivalent in difficulty to driving. One group was left undistracted while the other had to engage in a conversation about their hobbies using a speakerphone. As Dr Kunar and Dr Horowitz report in Psychonomic Bulletin & Review, those who were making the equivalent of a hands-free call had an average reaction time 212 milliseconds slower than those who were not. That, they calculate, would add 5.7 meters to the braking distance of a car traveling at 100kph. They found that the group using the hands-free kit made 83 percent more errors in their tasks than those who were not talking.They also explored the effect of simply listening to something—such as a radio programme. For this they played a recording of the first chapter of Bram Stoker’s “Dracula”. Even though the test subjects were told to pay attention because they would be asked questions about the story afterwards, it had little effect on their reaction times. The research led by Frank Drews of the University of Utah suggests the same thing is true of the idle chatter of a passenger. Dr Kunar reckons that having to think about responses during a phone conversation competes for the brain’s resources in a way that listening to a monologue does not.Punishing people for using hand-held gadgets while driving is difficult enough, even though they can be seen from outside the car. Stopping people making hands-free calls would probably be impossible—especially because more and more vehicles are now being fitted with the necessary equipment as standard. Persuading people to switch their phones off altogether when they get behind the wheel might be the only answer. Who knows, they might even come to enjoy not having to take calls. And they’ll be likelier to arrive in one piece.69. Which body part is most affected by talking into a cell phone when driving?A. Hands.B. Feet.C. Eyes.D. The brain.70. In Kunar and Horowitz’s experiments, the subjects who performed tasks while talking ________.A. reacted more quickly and made fewer mistakesB. reacted more quickly, but made more mistakesC. reacted more slowly, but made fewer mistakesD. reacted more slowly and made more mistakes71. According to Frank Drews, a chat with passengers ________.A. affects drivers more than a phone conversationB. affects drivers more than listening to a storyC. has less effect on the drivers than a phone conversationD. has less effect on the drivers than listening to a story72.

The best hope of stopping people using hands-free phones lies with ________.A. the lawmakersB. car manufacturersC. drivers themselvesD. new technology74. The purpose of the passage is to ________.A. inform people of the danger of using phones while drivingB. call on lawmakers to make new road laws on the use of cell phonesC. offer suggestions for drivers who use cell phones while drivingD. weigh the benefits and harms of using phones when drivingPassage FiveIn these times of fast media and ever-growing Internet, we are under so many external influences that it is anything but easy to think for ourselves. Unless you are a cunning, very aware person, you most likely don't even know when your thinking is not your own.Not that all outside influence is bad to forming your own views, but being unable to think for yourself can make you miserable at best, or a puppe t of someone else’s programming, at worst.Admittedly, we are all born into societies or cultures where the norms and customs are already established. We have little choice but to conform to what is already in place. This is not necessarily a bad thing, however, it can be confining and controlling if we accept everything blindly and never question the status quo.Does this mean all of your ideas can be original and unlike everyone else’s? Not at all!Nor does it require being contrary and argumentative just to be defiant or stand out. To think for yourself means that whatever opinions you hold will be well thought out and arise from。

You should write at least 150 words but no more than 200 words.The Impact of the Internet on Interpersonal CommunicationPart Ⅱ Reading Comprehension (Skimming and Scanning)(15minutes)Directions: In this part. You will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked A)、B)、C)and D). For questions 8-10, complete the sentences with the information given in the passage.The Three-Year SolutionHartwick College, a small liberal-arts school in upstate New York, makes New York, makes this offer to well prepared students: earn your undergraduate degree in three years instead of four, and save about 543,000—the amount of one year’s tuition and fees. A number of innovative colleges are making the same offer to students anxious about saving time and money. That’s both an opportunity and a warning for the best higher-education system in the world.The United States has almost all of the world’s best universities. A recent Chinese survey ranks 35 American universities among the top 50, eight among the top 10. Our research universities have been the key to developing the competitiveadvan tages that help Americans produce 25% of all the world’s wealth. In 2007, 623,805 of the world’s brightest students were attracted to American universities.Yet, there are signs of peril (危险)within American higher education. U.S. colleges have to compete in the marketplace. Students may choose among 6,000 public, private, nonprofit, for profit, or religious institutions of higher learning. In addition, almost all of the 532 billion the federal government provides for university research is awarded competitively.But many colleges and universities are stuck in the past. For instance, the idea of the fall-to-spring“school year”hasn’t changed much since before the American Revolution, when we were a summer stretch no longer makes sense. Former George Washington University president Stephen Trachtenberg estimates that a typical college uses its facilities for academic purposes a little more than half the calendar year.“While college facilities sit idle, they continue to generate maintenance expenses that cont ribute to the high cost of running a college,” he has written.Within academic departments, tenure(终身职位),combined withage-discrimination laws, makes faculty turnover—critical for a university to remain current in changing times—difficult. Instead of protecting speech and encouraging diversity and innovative thinking, the tenure system often stifles(压制)them: younger professors must win the approval of established colleagues for tenure, encouraging like-mindedness and sometimes inhibiting the free flow of ideas.Meanwhile, tuition has soared, leaving graduating students with unprecedented loan debt. Strong campus presidents to manage these problems are becoming harder to find, and to keep. In fact, students now stay on campus almost as long as their presidents. The average amount of time students now take to complete an undergraduate degree has stretched to six years and seven months as students interrupted by work, inconvenienced by unavailable classes, or lured by one more football season find it hard to graduate.Congress has tried to help students with college costs through Pell Grants and other forms of tuition support. But some of their fixes have made the problem worse. The stack of congressional regulations governing federal student grants and loans now stands twice as tall as I do. Filling out these forms consumes 7% of every tuition dollar.For all of these reasons, some colleges like Hartwick are rethinking the old way of doing things and questioning decades-old assumptions about what a college degree means. For instance, why does it have to take four years to earn a diploma? This fall, 16 first-year students and four second-year students at Hartwick enrolled in the school’s new three year degree program. According to the college, the plan is designed for high-ability, highly motivated student who wish to save money or to move along more rapidly toward advanced degrees.By eliminating that extra year, there year degree students save 25% in costs. Instead of taking 30 credits a year, these students take 40. During January, Hartwick runs a four week course during which students may earn three to four credits on or off campus, including a number of international sites. Summer courses are not required, but a student may enroll in them—and pay extra. Three year students get first crack at course registration. There are no changes in the number of courses professors teach or in their pay.The three-year degree isn’t a new idea. Geniuses have always breezed through. Judson College, a 350-student institution in Alabama, has offered students athree-year option for 40 years. Students attend “short terms” in May and June to earnthe credits required for graduation. Bates College in Maine and Ball State University in Indiana are among other colleges offering three-year options.Changes at the high-school level are also helping to make it easier for many students to earn their undergraduate degrees in less time. One of five students arrives at college today with Advanced Placement (AP) credits amounting to a semester or more of college level work. Many universities, including large schools like the University of Texas, make it easy for these AP students to graduate faster.For students who don’t plan to stop with an undergraduate degree, the three-year plan may have an even greater appeal. Dr. John Sergent, head of Vanderbilt University Medical School’s residency (住院医生) program, enrolled in Vanderbilt’s undergraduate college in 1959. He entered medical school after only three years as did four or five of his classmates.” My first year of medical school counted as my senior year, which meant I had to take three to four labs a week to get all my sciences in. I basically skipped my senior year,” says Sergent. He still had time to be a student senator and meet his wife.There are, however, drawbacks to moving through school at such a brisk pace. For one, it deprives students of the luxury of time to roam (遨游) intellectually. Compressing everything into three years also leaves less time for growing up, engaging in extracurricular activities, and studying abroad. On crowded campuses it could mean fewer opportunities to get into a prized professor’s class. Iowa’s Waldorf College has graduated several hundred students in its three-year degree program, but it now phasing out the option. Most Waldorf students wanted the full four-year experience—academically, socially, and athletically. And faculty members will be wary of any change that threatens the core curriculum in the name of moving students into the workforce.“Most high governmental officials seem to conceive of education in this light—as a way to ensure economic competitiveness and continued economic growth,” Derek Bok, former president of Harvard, told The Washington Post. “I strongly disagree with this ap proach.” Another risk: the new campus schedules mighteventually produce less revenue for the institution and longer working hours for faculty members.Adopting a three-year option will not come easily to most school. Those that wish to tackle tradition and make American campus more cost-conscious may find it easier to take Trachtenberg’s advice: open campuses year-round.“You could run two complete colleges, with two complete faculties,”he says.“That’s without cutting the length of students’ vacations, in creasing class sizes, or requiring faculty to teach more.”Whether they experiment with three-year degrees, offer year-round classes, challenge the tenure system—or all of the above—universities are slowly realizing that to stay competitive and relevant they must adapt to a rapidly changing world.Expanding the three-year option may be difficult, but it may be less difficult than asking Congress for additional financial help, asking legislators for more state support, or asking students even higher tuition payments. Campuses willing to adopt convenient schedules along with more focused, less-expensive degrees may find that they have a competitive advantage in attracting bright, motivated students. These sorts of innovations can help American universities avoid the perils of success.注意:此部分试题请在答题卡1上作答。

Instead of answering directly, the daughter tells her father to read her blog. It is common that youngsters nowadays incline to communicate with others on internet increasingly, and lack communication with people around them. With the development of Internet, it has influenced our society to a large extent, especially interpersonal communication. To begin with, we can communicate with others anytime via internet. Otherwise, we would have to arrange our schedules strictly in advance. Also, interpersonal communication through the internet is not restricted by space. For example, in most multinational corporations, instant messages and video conferences help colleagues solve problems timely and efficiently. Last but not least, the internet can greatly speed up our interpersonal communication. Whereas, there are also disadvantages that the internet brings to us. More and more people complained that they have lost face-to-face communicating skills. As a result, people become more and more indifferent to each other in real life. Some netizens who are immersed in virtual world even have difficulty in making friends in reality.In conclusion, communication through the internet could bring us both convenience and inconvenience. We should strike a balance between them and make the best of the internet.作文高分版The Impact of the Internet on Interpersonal CommunicationToday I saw an interesting cartoon, in which a father asked his daughter about her school performance of the day, and the daughter replied that he could go to her blog to check it. This small cartoon indicates a big change in our life, especially the way people communicate.Internet enables people to break though the limitations of distance, strengthening social network. Unlike post offices, Internet service with its convenience helps people engage and converse real time with their parents, soul mates, friends though emails, IRC, micro blog anytime, anywhere with a network terminal, without suffering the long and painful wait for a reply.Besides, such online communities as Twitter, Facebook are well under way and becoming the most dominating platforms for on-line social activities. These communities offer great opportunities for us to follow and interactwith those we like and even those celebrities. It is also a platform for us to share and update information of each other, and learn the outside world.Internet today and tomorrow is a virtual space where we live, where we learn, where we speak, and where we communicate.Part II Reading Comprehension (Skimming and Scanning) (15 minutes)1.

You should write at least 150 words but no more than 200 words.The Impact of the Internet on Interpersonal CommunicationPart ⅡReading Comprehension (Skimming and Scanning)(15minutes)Directions: In this part. You will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked A)、B)、C)and D). For questions 8-10, complete the sentences with the information given in the passage.The Three-Year SolutionHartwick College, a small liberal-arts school in upstate New York, makes New York, makes this offer to well prepared students: earn your undergraduate degree in three years instead of four, and save about 543,000—the amount of one year’s tuition and fees. A number of innovative colleges are making the same o ffer to students anxious about saving time and money. That’s both an opportunity and a warning for the best higher-education system in the world.The United States has almost all of the world’s best universities. A recent Chinese survey ranks 35 American universities among the top 50, eight among the top 10. Our research universities have been the key to developing the competitive advantages that help Americans produce 25% of all the world’s wealth. In 2007, 623,805 of the world’s brightest students were attracted to American universities.Yet, there are signs of peril (危险)within American higher education. U.S. colleges have to compete in the marketplace. Students may choose among 6,000 public, private, nonprofit, for profit, or religious institutions of higher learning. In addition, almost all of the 532 billion the federal government provides for university research is awarded competitively.But many colleges and universities are stuck in the past. For instance, the idea of thefall-to-spring“school year”hasn’t changed much since before the American Revolution, when we were a summer stretch no longer makes sense. Former George Washington University president Stephen Trachtenberg estimates that a typical college uses its facilities for academic purposes a little more than half the calendar year.“While college facilities sit idle, they continue to generate maintenance expenses that contribute to the high cost of running a college,” he has written.Within academic departments, tenure(终身职位),combined with age-discrimination laws, makes faculty turnover—critical for a university to remain current in changing times—difficult. Instead of protecting speech and encouraging diversity and innovative thinking, the tenure system often stifles(压制)them: younger professors must win the approval of established colleagues for tenure, encouraging like-mindedness and sometimes inhibiting the free flow of ideas.Meanwhile, tuition has soared, leaving graduating students with unprecedented loan debt. Strong campus presidents to manage these problems are becoming harder to find, and to keep. In fact, students now stay on campus almost as long as their presidents. The average amount of timestudents now take to complete an undergraduate degree has stretched to six years and seven months as students interrupted by work, inconvenienced by unavailable classes, or lured by one more football season find it hard to graduate.Congress has tried to help students with college costs through Pell Grants and other forms of tuition support. But some of their fixes have made the problem worse. The stack of congressional regulations governing federal student grants and loans now stands twice as tall as I do. Filling out these forms consumes 7% of every tuition dollar.For all of these reasons, some colleges like Hartwick are rethinking the old way of doing things and questioning decades-old assumptions about what a college degree means. For instance, why does it have to take four years to earn a diploma? This fall, 16 first-year students and four second-year students at Hartwick enrolled in the school’s new three year degree program. According to the college, the plan is designed for high-ability, highly motivated student who wish to save money or to move along more rapidly toward advanced degrees.By eliminating that extra year, there year degree students save 25% in costs. Instead of taking 30 credits a year, these students take 40. During January, Hartwick runs a four week course during which students may earn three to four credits on or off campus, including a number of international sites. Summer courses are not required, but a student may enroll in them—and pay extra. Three year students get first crack at course registration. There are no changes in the number of courses professors teach or in their pay.The three-year degree isn’t a new idea. Geniuses have always breezed through. Judson College, a 350-student institution in Alabama, has offered students a three-year option for 40 years. Students attend “short terms” in May and June to earn the credits r equired for graduation. Bates College in Maine and Ball State University in Indiana are among other colleges offeringthree-year options.Changes at the high-school level are also helping to make it easier for many students to earn their undergraduate degrees in less time. One of five students arrives at college today with Advanced Placement (AP) credits amounting to a semester or more of college level work. Many universities, including large schools like the University of Texas, make it easy for these AP students to graduate faster.For students who don’t plan to stop with an undergraduate degree, the three-year plan may have an even greater appeal. Dr. John Sergent, head of Vanderbilt University Medical School’s residency (住院医生) program, enrolled in Vanderbilt’s undergraduate colle ge in 1959. He entered medical school after only three years as did four or five of his classmates.” My first yearof medical school counted as my senior year, which meant I had to take three to four labs a week to get all my sciences in. I basically skipp ed my senior year,” says Sergent. He still had time to be a student senator and meet his wife.There are, however, drawbacks to moving through school at such a brisk pace. For one, it deprives students of the luxury of time to roam (遨游) intellectually. Compressing everything into three years also leaves less time for growing up, engaging in extracurricular activities, and studying abroad. On crowded campuses it could mean fewer opportunities to get into a prized professor’s class. Iowa’s Waldorf College has graduated several hundred students in its three-year degree program, but it now phasing out the option. Most Waldorf students wanted the fullfour-year experience—academically, socially, and athletically. And faculty members will be waryof any change that threatens the core curriculum in the name of moving students into the workforce.“Most high governmental officials seem to conceive of education in this light—as a way to ensure economic competitiveness and continued economic growth,” Derek Bok, former president of Harvard, told The Washington Post. “I strongly disagree with this approach.” Another risk: the new campus schedules might eventually produce less revenue for the institution and longer working hours for faculty members.Adopting a three-year option will not come easily to most school.

For questions 8-10, complete the sentences with the information given in the passage.The Three-Year SolutionHartwick College, a small liberal-arts school in upstate New York, makes New York, makes this offer to well prepared students: earn your undergraduate degree in three years instead of four, and save about 543,000—the amount of one year’s tuition and fees. A number of innovative colleges are making the same offer to students anxious about saving time and money. That’s both an opportunity and a warning for the best higher-education system in the world.The United States has almost all of the world’s best universities. A recent Chinese survey ranks 35 American universities among the top 50, eight among the top 10. Our research universities have been the key to developing the competitive advantages that help Americans produce 25% of all the world’s wealth. In 2007, 623,805 of the world’s brightest students were attracted to American universities.Yet, there are signs of peril (危险)within American higher education. U.S. colleges have to compete in the marketplace. Students may choose among 6,000 public, private, nonprofit, for profit, or religious institutions of higher learning. In addition, almost all of the 532 billion the federal government provides for university research is awarded competitively.But many colleges and universities are stuck in the past. For instance, the idea of the fall-to-spring“school year”hasn’t changed much since before the American Revolution, when we were a summer stretch no longer makes sense. Former George Washington University president Stephen Trachtenberg estimates that a typical college uses its facilities for academic purposes a little more than half the calendar year.“While collegefacilities sit idle, they continue to generate maintenance expenses that contribute to the high cost of running a college,” he has written.Within academic departments, tenure(终身职位),combined with age-discrimination laws, makes faculty turnover—critical for a university to remain current in changing times—difficult. Instead of protecting speech and encouraging diversity and innovative thinking, the tenure system often stifles(压制)them: younger professors must win the approval of established colleagues for tenure, encouraging like-mindedness and sometimes inhibiting the free flow of ideas.Meanwhile, tuition has soared, leaving graduating students with unprecedented loan debt. Strong campus presidents to manage these problems are becoming harder to find, and to keep. In fact, students now stay on campus almost as long as their presidents. The average amount of time students now take to complete an undergraduate degree has stretched to six years and seven months as students interrupted by work, inconvenienced by unavailable classes, or lured by one more football season find it hard to graduate.Congress has tried to help students with college costs through Pell Grants and other forms of tuition support. But some of their fixes have made the problem worse. The stack of congressional regulations governing federal student grants and loans now stands twice as tall as I do. Filling out these forms consumes 7% of every tuition dollar.For all of these reasons, some colleges like Hartwick are rethinking the old way of doing things and questioning decades-old assumptions about what a college degree means. For instance, why does it have to take four years to earn a diploma? This fall, 16 first-year students and four second-year students at Hartwick enrolled in the school’s new three year degree program. According to the college, the plan is designed for high-ability,highly motivated student who wish to save money or to move along more rapidly toward advanced degrees.By eliminating that extra year, there year degree students save 25% in costs. Instead of taking 30 credits a year, these students take 40. During January, Hartwick runs a four week course during which students may earn three to four credits on or off campus, including a number of international sites. Summer courses are not required, but a student may enroll in them—and pay extra. Three year students get first crack at course registration. There are no changes in the number of courses professors teach or in their pay.The three-year degree isn’t a new idea. Geniuses have always breezed through. Judson College, a 350-student institution in Alabama, has offered students a three-year option for 40 years. Students attend “short terms” in May and June to earn the credits required for graduation. Bates College in Maine and Ball State University in Indiana are among other colleges offering three-year options.Changes at the high-school level are also helping to make it easier for many students to earn their undergraduate degrees in less time. One of five students arrives at college today with Advanced Placement (AP) credits amounting to a semester or more of college level work. Many universities, including large schools like the University of Texas, make it easy for these AP students to graduate faster.For students who don’t plan to stop with an undergraduate degree, the three-year plan may have an even greater appeal. Dr. John Sergent, head of Vanderbilt University Medical School’s residency (住院医生) program, enrolled in Vanderbilt’s undergraduate college in 1959. He entered medical school after only three years as did four or five of hisclassmates.” My first year of medical school counted as my senior year, which meant I had to take three to four labs a week to get all my sciences in. I basically skipped my senior year,” says Sergent. He still had time to be a student senator and meet his wife.There are, however, drawbacks to moving through school at such a brisk pace. For one, it deprives students of the luxury of time to roam (遨游) intellectually. Compressing everything into three years also leaves less time for growing up, engaging in extracurricular activities, and studying abroad. On crowded campuses it could mean fewer opportunities to get into a prized professor’s class. Iowa’s Waldorf College has graduated several hundred students in its three-year degree program, but it now phasing out the option. Most Waldorf students wanted the full four-year experience—academically, socially, and athletically. And faculty members will be wary of any change that threatens the core curriculum in the name of moving students into the workforce.“Most high governmental officials seem to conceive of education in this light—as a way to ensure economic competitiveness and continued economic growth,” Derek Bok, former president of Harvard, told The Washington Post. “I strongly disagree with this approach.” Another risk: the new campus schedules might eventually produce less revenue for the institution and longer working hours for faculty members.Adopting a three-year option will not come easily to most school. Those that wish to tackle tradition and make American campus more cost-conscious may find it easier to take Trachtenberg’s advice: open campuses year-round.“You could run two complete colleges, with two complete faculties,”he says.“That’s without cutting the length of students’vacations, increasing class sizes, or requiring faculty to teach more.”Whether they experiment with three-year degrees, offer year-round classes, challenge the tenure system—or all of the above—universities are slowly realizing that to stay competitive and relevant they must adapt to a rapidly changing world.Expanding the three-year option may be difficult, but it may be less difficult than asking Congress for additional financial help, asking legislators for more state support, or asking students even higher tuition payments. Campuses willing to adopt convenient schedules along with more focused, less-expensive degrees may find that they have a competitive advantage in attracting bright, motivated students. These sorts of innovations can help American universities avoid the perils of success.注意:此部分试题请在答题卡1上作答。

2012年6月全国大学英语六级考试试卷PartⅣReading Comprehension(Reading in Depth) (25minutes)Section ADirections: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer Sheet 2Questions 47 to 51 are based on the following passage.In face of global warming, much effort has been focused on reducing greenhouse gas emissions through a variety of strategies. But while much of the research and innovation has concentrated on finding less-polluting energy alternatives, it may be decades before clean technologies like wind and solar meet a significant portion of our energy needs.In the meantime, the amount of CO2 in the air is rapidly approaching the limits proposed by the Intergovernmental Panel on Climate Change (IPCC). “As long as we’re consuming fossil fuels, we’re putting out CO2,”says Klaus Lackner, a geophysicist at Columbia, University” We cannot let the CO2 in the atmosphere rise indefinitely.”That sense of urgency has increased interest in capturing and storing CO2, which the IPCC says could provide the more than 50% reduction in emissions thought needed to reduce global warming.“We see the potential for capture and storage to play an integra l role in reducing emissions,” says Kim Corley, Shell’s senior advisor of CO2 and environmental affairs. That forward thinking strategy is gaining support. The U.S. Department of Energy recently proposed putting $1 billion into a new $2.4 billion coal-burn ing energy plant. The plant’s carbon-capture technologies would serve as a pilot project for other new coal-burning plants.But what do you do with the gas once you’ve captured it? One option is to put it to new uses. Dakota Gasification of North Dakota captures CO2 at a plant that converts coal into synthetic natural gas. It then ships the gas 200 miles by pipeline to Canada, where it is pumped underground in oil recovery operations. In the Netherlands, Shell delivers CO2 to farmers who pipe it into their greenhouses, increasing their yield of fruits and vegetables.However, scientists say that the scale of CO2 emissions will require vast amounts of long-term storage. Some propose storing the CO2 in coal mines or liquid storage in the ocean, Shell favors storing CO2 in deep geological structures such as saline(盐的) formations and exhausted oil and gas fields that exist throughout the world.注意:此部分试题请在答题卡2上作答。

The problem, Schweitzer says, is the actual trades were not profitable. Other studies have shown that saddling employees with unrealistic goals can compel them to lie, cheat or steal. Such was the case in the early 1990s when Sears imposed a sales quota on its auto repair staff. staff. It It It prompted prompted prompted employees employees employees to to to overcharge overcharge overcharge for for for work work work and and and to to to complete complete complete unnecessary unnecessary unnecessary repairs repairs repairs on on on a a companywide basis. Schweitzer concedes his research runs counter to a very large body of literature that commends the many benefits of goal-setting. Advocates of the practice have taken issue with his team’s use of such evidence as news accounts to support his conclusion that goal-setting is widely over-prescribed In a rebuttal (反驳) paper, Dr. Edwin Locke writes:“Goal-setting is not going away. Organizations cannot thrive without being focused on their desired end results any more than an individual can thrive without goals to provide a sense of purpose.”But Schweitzer contends the “mounting causal evidence” linking goal -setting and harmful behavior sh should ould ould be be be studied studied studied to to to help help help spotlight spotlight spotlight issues issues issues that that that merit merit merit caution caution caution and and and further further further investigation. investigation. investigation. “Even “Even “Even a a a few few negative effects could be so large that they outweigh many positive effects,” he says.“Goal “Goal-setting does help -setting does help coordinate and motivate people. My idea would be to combine that with careful oversight, a strong organizational culture, and make sure the goals that you use are going to be constructive and not significantly harm the organization,” Schweitzer says.52. What message does the author try to convey about goal-setting? A) Its negative effects have long been neglected. B) The goal increase people’s work efficiency.C) Its role has been largely underestimated. D) The goals most people set are unrealistic. 53.

Directions:For this part,you are allowed30minutes to write a composition on the topic The Impact of the Internet on Interpersonal Communication.You should write at least150words but no more than200words.The Certificate CrazePart II Reading Comprehension(Skimming and Scanning)(15minutes) Directions:In this part,you will have15minutes to go over the passage quickly and answer the questions on Answer Sheet1.For questions1-7,choose the best answer from the fourchoices marked A),B),C)and D).For questions8-10,complete the seen tenses withthe information given in the passage.The Three-Year SolutionHartwick College,a small liberal-arts school in upstate New York,makes New York,makes this offer to well prepared students:earn your undergraduate degree in three years instead of four, and save about543,000—the amount of one year’s tuition and fees.A number of innovative colleges are making the same offer to students anxious about saving time and money.That’s both an opportunity and a warning for the best higher-education system in the world.The United States has almost all of the world’s best universities.A recent Chinese survey ranks35American universities among the top50,eight among the top10.Our research universities have been the key to developing the competitive advantages that help Americans produce25%of all the world’s wealth.In2007,623,805of the world’s brightest students were attracted to American universities.Yet,there are signs of peril(危险)within American higher education.U.S.colleges have to compete in the marketplace.Students may choose among6,000public,private,nonprofit,for profit, or religious institutions of higher learning.In addition,almost all of the532billion the federal government provides for university research is awarded competitively.But many colleges and universities are stuck in the past.For instance,the idea of thefall-to-spring“school year”hasn’t changed much since before the American Revolution,when we were a summer stretch no longer makes sense.Former George Washington University president Stephen Trachtenberg estimates that a typical college uses its facilities for academic purposes a little more than half the calendar year.“While college facilities sit idle,they continue to generate maintenance expenses that contribute to the high cost of running a college,”he has written.Within academic departments,tenure(终身职位),combined with age-discrimination laws, makes faculty turnover—critical for a university to remain current in changing times—difficult. Instead of protecting speech and encouraging diversity and innovative thinking,the tenure system often stifles(压制)them:younger professors must win the approval of established colleagues for tenure,encouraging like-mindedness and sometimes inhibiting the free flow of ideas.Meanwhile,tuition has soared,leaving graduating students with unprecedented loan debt. Strong campus presidents to manage these problems are becoming harder to find,and to keep.Infact,students now stay on campus almost as long as their presidents.The average amount of time students now take to complete an undergraduate degree has stretched to six years and seven months as students interrupted by work,inconvenienced by unavailable classes,or lured by one more football season find it hard to graduate.Congress has tried to help students with college costs through Pell Grants and other forms of tuition support.But some of their fixes have made the problem worse.The stack of congressional regulations governing federal student grants and loans now stands twice as tall as I do.Filling out these forms consumes7%of every tuition dollar.For all of these reasons,some colleges like Hartwick are rethinking the old way of doing things and questioning decades-old assumptions about what a college degree means.For instance, why does it have to take four years to earn a diploma?This fall,16first-year students and four second-year students at Hartwick enrolled in the school’s new three year degree program. According to the college,the plan is designed for high-ability,highly motivated student who wish to save money or to move along more rapidly toward advanced degrees.By eliminating that extra year,there year degree students save25%in costs.Instead of taking 30credits a year,these students take40.During January,Hartwick runs a four week course during which students may earn three to four credits on or off campus,including a number of international sites.Summer courses are not required,but a student may enroll in them—and pay extra.Three year students get first crack at course registration.There are no changes in the number of courses professors teach or in their pay.The three-year degree isn’t a new idea.Geniuses have always breezed through.Judson College, a350-student institution in Alabama,has offered students a three-year option for40years.Students attend“short terms”in May and June to earn the credits required for graduation.Bates College in Maine and Ball State University in Indiana are among other colleges offering three-year options.Changes at the high-school level are also helping to make it easier for many students to earn their undergraduate degrees in less time.One of five students arrives at college today with Advanced Placement(AP)credits amounting to a semester or more of college level work.Many universities,including large schools like the University of Texas,make it easy for these AP students to graduate faster.For students who don’t plan to stop with an undergraduate degree,the three-year plan may have an even greater appeal.Dr.John Sergent,head of Vanderbilt University Medical School’s residency(住院医生)program,enrolled in Vanderbilt’s undergraduate college in1959.He entered medical school after only three years as did four or five of his classmates.”My first year of medical school counted as my senior year,which meant I had to take three to four labs a week to get all my sciences in.I basically skipped my senior year,”says Sergent.He still had time to be a student senator and meet his wife.There are,however,drawbacks to moving through school at such a brisk pace.For one,it deprives students of the luxury of time to roam(遨游)pressing everything into three years also leaves less time for growing up,engaging in extracurricular activities,and studying abroad.On crowded campuses it could mean fewer opportunities to get into a prized professor’s class.Iowa’s Waldorf College has graduated several hundred students in its three-year degree program,but it now phasing out the option.Most Waldorf students wanted the full four-year experience—academically,socially,and athletically.And faculty members will be wary of any change that threatens the core curriculum in the name of moving students into the workforce.“Most high governmental officials seem to conceive of education in this light—as a way to ensure economic competitiveness and continued economic growth,”Derek Bok,former president of Harvard,told The Washington Post.“I strongly disagree with this approach.”Another risk:the new campus schedules might eventually produce less revenue for the institution and longer working hours for faculty members.Adopting a three-year option will not come easily to most school.Those that wish to tackle tradition and make American campus more cost-conscious may find it easier to take Trachtenberg’s advice:open campuses year-round.“You could run two complete colleges,with two complete faculties,”he says.“That’s without cutting the length of students’vacations,increasing class sizes,or requiring faculty to teach more.”Whether they experiment with three-year degrees,offer year-round classes,challenge the tenure system—or all of the above—universities are slowly realizing that to stay competitive and relevant they must adapt to a rapidly changing world.Expanding the three-year option may be difficult,but it may be less difficult than asking Congress for additional financial help,asking legislators for more state support,or asking studentseven higher tuition payments.Campuses willing to adopt convenient schedules along with more focused,less-expensive degrees may find that they have a competitive advantage in attracting bright, motivated students.These sorts of innovations can help American universities avoid the perils of success.注意:此部分试题请在答题卡1上作答。

Conversation 1 W: One of the most interesting experiments with dolphins must be one done by Doctor Jarvis Bastian. What he tried to do was to teach a male dolphin called Bass and a female called Doris to communicate with each other across a solid barrier. M: So how did he do it exactly? W: Well, first of all, he kept the two dolphins together in the same tank and taught them to press levers whenever they saw a light. The levers were fitted to the side of the tank next to each other. If the light flashed on and off several times, the dolphins were supposed to press the left-hand lever followed by the right-hand one. If the light was kept steady, the dolphins were supposed to press the levers in reverse order. Whenever they responded correctly, they were rewarded with fish. M: Sounds terribly complicated. W: Well, that was the first stage. In the second stage, Doctor Bastian separated the dolphins into two tanks. They could still hear one another, but they couldn’t actually see each other. The levers and light were set up in exactly the same way except that this time it was only Doris who could see the light indicating which lever to press first. But in order to get their fish, both dolphins had to press the levers in the correct order. This meant of course that Doris had to tell Bass whether it was a flashing light or whether it was a steady light. M: So did it work? W: Well, amazingly enough, the dolphins achieved a 100 % success rate. Questions 19-21 are based on the conversation you have just heard. Q19. What is the purpose of Doctor Jarvis Bastian’s experiment? Q20. What were the dolphins supposed to do when they saw a steady light? Q21. How did the second stage of the experiment differ from the first stage? 答案: 19. D) to see if dolphins can communicate with each other. 20. A) Press the right-hand lever first. 21. C) Only one dolphin was able to see the light. 【解析】 这篇长对话主要围绕巴斯蒂安博⼠关于海豚的实验⽽展开,实验的⽬的是要教会海豚学会互相沟通和交流讯息。
