Dr. Taylar, Professor of Sociology at University of Oxford, has written numerous articles and books on the topic of love, which is the most simple but important issue i ，everybody's life. Welcome, Dr. Taylor.Dr. Taylor:Good morning, everyone. I' m sure you all have got some deep feelings of lif e. And you may have tried different kinds of descriptions of your own lif e. What I want to tell you today is that life comes in a package. This package includes happiness and sorrow, success and failure, hope and despair. Life is a learning process . Experiences in life teach us new lessons and make us a better person. With each passing day we learn to handle various situations .First, let's talk about love.Love plays an important role in our life . Love makes you feel wanted. Without love a person could become cruel. In the early stage of our life, our parents are the ones who shower us with unconditional love and care. They teach us about what is right and wrong, good and bad. But we always tend to take this for granted. It is only after marriage and having kids that a person understands and becomes sensitive to others' feelings. Kids make a person responsible and mature and help us to understand life better.Second, do you think you are a happy person?Materialistic happiness is short-lived, but happiness achieved by bringing a smile on others' face gives a certain level of fulfillment. Peace of mind is the main link to happiness. No mind is happy without peace. We realize the true worth of happiness when we are in sorrow. Sorrow is basically due to death of a loved one, failure and despair. But these things are temporary and will easily pass away. Third, I' m sure you all have experienced success as well as failure.Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows us a specific way. Success brings in money, fame, pride and self-respect. Here it becomes very important to keep our head on our shoulder. The only way to show our gratitude to God for giving us success is by being humble, modest and respectful to the less fortunate ones.The last I want to share with you is about hope and despair.Hope is what keeps life going. Parents always hope their children do well. Hope makes us dream. Hope builds in patience. Life teaches us not to despair even in the darkest hour, because after every night there is a day. Nothing remains the same . We have only one choice : keep moving on in life and be hopeful. Life teaches us not to regret over yesterday, for it has passed and is beyond our control. Tomorrow is unknown, for it could either be bright or dull. So the only alternative is working hard today, so that we will enjoy a better tomorrow.After all of these, have you got a totally brand new feeling towards your own life? Or maybe you will have a different opinion about what you have experienced before? I do hope that you will understand life better. Thank you!What does the introduction say about the topic of love?［解析］主持人介绍说，''爱〃这个话题最为简单，但是却在每个人的生活中至关重要，故答案为Bo2、 A［听力原文］What is the main link to happiness according to Dr. Taylor? 29A. HeB. HeC. HeD. He 30、 A. It B. It［解析］根据定位句可知，泰勒博士认为精神上的安宁是与幸福最主要的联系，故答案为A。

大学英语六级分类模拟题450(总分：497.00，做题时间：90分钟)一、Reading Comprehension(总题数：0，分数：0.00)二、Section A(总题数：1，分数：71.00)The Uses of DifficultyThe brain likes a challenge - and putting a few obstacles in its way may well. boost its creativity.[A] Jack White, the former frontman of the White Stripes and an influential figure among fellow musicians, likes to make things difficult for himself. He uses cheap guitars that won"t stay in shape or in tune. When performing, he positions his instruments in a way that is deliberately inconvenient, so that switching from guitar to organ mid-song involves a mad dash across the stage. Why? Because he"s on the run from what he describes as a disease that preys on every artist: "ease of use". When making music gets too easy, says White, it becomes harder to make it sing. [B] It"s an odd thought. Why would anyone make their work more difficult than it already :is? Yet we know that difficulty can pay unexpected dividends. In 1966, soon after the Beatles had finished work on "Rubber Soul", Paul McCartney looked into the possibility of going to America to record their next album. The equipment in American studios was more advanced than anything in Britain. which had led the Beatles" great rivals, the Rolling Stones, to make their latest album, "Aftermath", in Los Angeles. McCartney found that EMI"s (百代唱片) contractual clauses made it prohibitively expensive to follow suit, and the Beatles had to make do with the primitive technology of Abbey Road.[C] Lucky for us. Over the next two years they made their most groundbreaking work, trolling the recording studio into a magical instrument of its own. Precisely because they were working with old-fashioned machines, George Martin and his team of engineers were forced to apply every ounce of their creativity to solve the problems posed to them by Lennon and McCartney. Songs like "Tomorrow Never Knows", "Strawberry Fields Forever", and "A Day in the Life" featured revolutionary sound effects that dazzled and mystified Martin"s American counterparts.[D] Sometimes it"s only when a difficulty is removed that we realise what it was doing for us. For more than two decades, starting in the 1960s, the poet Ted Hughes sat on the judging panel of an annual poetry competition for British schoolchildren. During the 1980s he noticed an increasing number of long poems among the submissions, with some running to 70 or 80 pages. These poems were verbally inventive and fluent, but also "strangely boring". After making inquiries Hughes discovered that they were being composed on computers, then just finding their way into British homes.[E] You might have thought any tool which enables a writer to get words on to the page would be an advantage. But there may be a cost to such facility. In an interview with the Paris Review Hughes speculated that when a person puts pen to paper, "you meet the terrible resistance of what happened your first year at it, when you couldn"t write at all". As the brain attempts to force the unsteady hand to do its bidding, the tension between the two results in a more compressed, psychologically denser expression. Remove that resistance and you are more likely to produce a 70-page ramble (不着边际的长篇大论).[F] Our brains respond better to difficulty than we imagine. In schools, teachers and pupils alike often assume that if a concept has been easy to learn, then the lesson has been successful. But numerous studies have now found that when classroom material is made harder to absorb, pupils retain more of it over the long term, and understand it on a deeper level.[G] As a poet, Ted Hughes had an acute sensitivity to the way in which constraints onself-expression, like the disciplines of metre and rhyme (韵律), spur creative thought. What applies to poets and musicians also applies to our daily lives. We tend to equate(等同) happiness with freedom, but, as the psychotherapist and writer Adam Phillips has observed, without obstacles to our desires it"s harder to know what we want, or where we"re heading. He tells the story of a patient, a first-time mother who complained that her young son was always clinging to her, wrapping himself around her legs wherever she went. She never had a moment to herself, she said, because her son was "always in the way". When Phillips asked her where she would go if he wasn"t in the way, she replied cheerfully, "Oh, I wouldn"t know where I was!"[H] Take another common obstacle: lack of money. People often assume that more money will make them happier. But economists who study the relationship between money and happiness have consistently found that, above a certain income, the two do not reliably correlate. Despite the ease with which the rich can acquire almost anything they desire, they are just as likely to be unhappy as the middle classes. In this regard at least, F. Scott Fitzgerald was wrong.[I] Indeed, ease of acquisition is the problem. The novelist Edward St Aubyn has a narrator remark of the very rich that, "not having to consider affordability, their desires rambled on like unstoppable bores, relentless (持续不断的) and whimsical (反复无常的) at the same time. " When Boston College, a private research university, wanted a better feel for its potential donors, it asked the psychologist Robert Kenny to investigate the mindset of the super-rich. He surveyed 165 households, most of which had a net worth of $25m or more. He found that many of his subjects were confused by the infinite options their money presented them with. They found it hard to know what to want, creating a kind of existential bafflement. One of them put it like this: "You know, Bob, you can just buy so much stuff, and when you get to the point where you can just buy so much stuff, now what are you going to do?"[J] The internet makes information billionaires out of all of us, and the architects of our online experiences are catching on to the need to make things creatively difficult. Twitter"s huge success is rooted in the simple but profound insight that in a medium with infinite space for self- expression, the most interesting thing we can do is restrict ourselves to 140 characters. The music service This Is My Jam helps people navigate the tens of millions of tracks now available instantly via Spotify and iTunes. Users pick their favourite song of the week to share with others. They only get to choose one. The service was only launched this year, but by the end of September 650,000 jams had been chosen. Its co-founder Matt Ogle explains its raison d"être (存在的理由) like this: "In an age of endless choice, we were missing a way to say: "This. This is the one you should listen to". "[K] Today"s world offers more opportunity than ever to follow the advice of the Walker Brothers and make it easy on ourselves. Compared with a hundred years ago, our lives are less tightly bound by social norms and physical constraints. Technology has cut out much of life"s donkeywork, and we have more freedoms than ever: we can wear what we like and communicate with hundreds of friends at once at the crick of a mouse. Obstacles are everywhere disappearing. Few of us wish to turn the clock back, but perhaps we need to remind ourselves how useful the right obstacles can be. Sometimes, the best route to fulfilment is the path of more resistance.（分数：71.00）(1).The rigorous requirements placed on the writing of poetry stimulate the poet"s creativity.（分数：7.10）解析：G [解析] [G]段第一句提到，作为诗人，特德·休斯对表达方式的禁忌及其敏感性，如韵律的规则，可促进其创造性思维。

Jacob Bjerknes pointed out over 20 years ago how winds might create either abnormally warm or abnormally cold water in the eastern equatorial Pacific. Nonetheless, until the development of the models no one could explain why conditions should regularly shift from one to the other, as happens in the periodic oscillations between appearances of the warm EI Nino and the cold so-called anti-El Nino. The answer, at least if the current model that links the behavior of the ocean to that of the atmosphere is correct, is to be found in the ocean.It has long been known that during an El Nino, two conditions exist: unusually warm water extends along the eastern Pacific, principally along the coasts of Ecuador and Peru, and winds blow from the west into the warmer air rising over the warm water in the east. These winds tend to create a feedback mechanism by driving the warmer surface water into a "pile" that blocks the normal upwelling of deeper, cold water in the east and further warms the eastern water, thus strengthening the wind still more. The contribution of the model is to show that the winds of an El Nino, which raise sea level in the cast, simultaneously send a signal to the west lowering sea level. According to the model, that signal is generated as a negative Rossby wave, a wave of depressed, or negative, sea level, that moves westward parallel to the equator at 25 to 85 kilometers per day. Taking months to traverse the Pacific, Rossby waves march to the western boundary of the Pacific basin, which is modeled as a smooth wall but in reality consists of quite irregular island chains, such as, the Philippines and Indonesia.When the waves meet the western boundary, they are reflected, and the model predicts that Rossby waves will be broken into numerous coastal Kelvin waves carrying the same negative sea-level signal. These eventually shoot toward the equator, and then head eastward along the equator propelled by the rotation of the Earth at a speed of about 250 kilometers per day. When enough Kelvin waves of sufficient amplitude arrive from the western Pacific, their negative sea-level signal overcomes the feedback mechanism tending to raise the sea level, and they begin to drive the system into the opposite cold mode. This produces a gradual shift in winds, one that will eventually send positive sea-level Rossby waves westward, waves that will eventually return as cold cycle-ending positive Kelvin waves, beginning another warming cycle.（分数：20.00）(1).Which of the following best describes the organization of the first paragraph?（分数：4.00）A.A model is described and its value assessed.B.A result is reported and its importance explained. √C.A phenomenon is noted and its significance debated.D.A hypothesis is introduced and contrary evidence presented.解析：[解析] 推断题。

大学英语六级分类模拟题372(总分100, 做题时间90分钟)Reading ComprehensionLargely for "spiritual reasons," Nancy Manos started home-schooling her children five years ago and has studiously avoided public schools ever since. Yet last week, she was enthusiastically enrolling her 8-year-old daughter, Olivia, in sign language and modern dance classes at Eagleridge Enrichment—a program run by the Mesa, Ariz, public schools are taught by district teachers. Manos still wants to handle the basics, but likes that Eagleridge offers the extras, "things I couldn"t teach." One doubt, though, lingers in her mind: why wouldthe public school system want to offer home-school families anything?A big part of the answer is economics. The number of home-schooled kids nationwide has risen to as many as 1.9 million from an estimated 345,000 in 1994, and school districts that get state and localdollars per child are beginning to suffer. In Maricopa County, which includes Mesa, the number of home-schooled kids has more than doubled during that period to 7,526; at about $4,500 a child, that"s nearly $34 million a year in lost revenue.Not everyone"s happy with these innovations. Some states have taken the opposite tack. Like about half of the states, West Virginia refuses to allow home-schooled kids to play public-school sports. And in Arizona, **plain that their tax dollars are being used to create programs for families who, essentially, eschew participation inpublic life. "That makes my teeth grit," says Daphne Atkeson, whose10-year-old son attends public school in Paradise Valley. Even**mitted home-schoolers question the new programs, given theircentral irony: they turn home-schoolers into public-school students, says Bob Parsons, president of the Alaska Private and Home Educators Association. "We"ve lost about one third of our members to those programs. They"re so enticing,"Mesa started Eagleridge four years ago, when it saw how much money it was losing from home-schoolers, and how unprepared some students were when they re-entered the schools. Since it began, the program"s enrolment has nearly doubled to 397, and last year the district moved Eagleridge to a strip mall (between a pizza joint and a laser-tag arcade). Parents typically drop off their kids once a week; because most of the children qualify as quarter-time students, the district collects $911 per child. "It"s like getting a taste of what real school is like," says 10-year-old Chad Lucas, who"s **puter animation and creative writing.Other school districts are also experimenting with novel ways tocourt home schoolers. The town of Galena, Alaska, (pop. 600) has just 178 students. But in 1997, its school administrators figured they could reach beyond their borders. Under the program, the district gives home-schooling families **puters and Internet service for correspondence classes. In return, the district gets $3,100 per student enrolled in the program—S9.6 million a year, which it has used partly for a new vocational school. Such alternatives just might appeal to other districts. Ernest Felty, head of Hardin County schools in southern Illinois, has 10 home-schooled pupils. That may not sound like much—except that he has a staff of 68, and at $4,500 a child, "that"s probably a teacher"s salary," Felty says. With the right robotics or art class, though, he could take the home out of home schooling.SSS_SINGLE_SEL1.What changes will Olivia face in the future?A She will face her mother"s punishment.B She will start to learn some knowledge in the public school.C Her mother Nancy Manos are likely to teach in the school.D Her home-learning is forbidden by government.分值: 4答案:B[解析] 细节题。

大学英语六级分类模拟题468(总分：270.50，做题时间：90分钟)一、Part Ⅰ Reading Comprehension(总题数：0，分数：0.00)二、Section A(总题数：1，分数：25.00)Norman Borlaug: Father of the "Green Revolution"A. Few people have quietly changed the world for the better more than this rural lad from the midwestern state of Iowa in the United States. The man in focus is Norman Borlaug, the Father of the " Green Revolution" , who died on September 12, 2009 at age 95. Norman Borlaug spent most of his 60 working years in the farmlands of Mexico, South Asia and later in Africa, fighting world hunger, and saving by some estimates up to a billion lives in the process. An achievement, fit for a Nobel Peace Prize.Early YearsB. "I"m a product of the great depression" is how Borlaug described himself. A great-grandson of Norwegian immigrants to the United States, Borlaug was born in 1914 and grew up on a small farm in the northeastern comer of Iowa in a town called Cresco. His family had a 40-hectare(公顷) farm on which they grew wheat, maize (玉米) and hay and raised pigs and cattle. Norman spent most of his time from age 7-17 on the farm, even as he attended a one-room, one-teacher school at New Oregon in Howard County.C. Borlaug didn"t have money to go to college. But through a Great Depression era programme, known as the National Youth Administration, Borlaug was able to enroll in the University of Minnesota at Minneapolis to study forestry. He excelled in studies and received his Ph.D. in plant pathology (病理学) and genetics in 1942. From 1942 to 1944, Borlaug was employed as a microbiologist at DuPont in Wilmington. However, following the December 7, 1941 attack on Pearl Harbor, Borlaug tried to join the military, but was rejected under wartime labour regulations.In MexicoD. In 1944, many experts warned of mass starvation in developing nations where populations were expanding faster than crop production. Borlaug began work at a Rockefeller Foundation-funded project in Mexico to increase wheat production by developing higher-yielding varieties of the crop. It involved research in genetics, plant breeding, plant pathology, entomology (昆虫学), agronomy (农艺学), soil science, and cereal technology. The goal of the project was to boost wheat production in Mexico, which at the time was importing a large portion of its grain. Borlaug said that his first couple of years in Mexico were difficult. He lacked trained scientists and equipment. Native farmers were hostile towards the wheat programme because of serious crop losses from 1939 to 1941 due to stem rust.E. Wheat varieties that Borlaug worked with had tall, thin stalks. While taller wheat competed better for sunlight, they had a tendency to collapse under the weight of extra grain—a trait called lodging. To overcome this, Borlaug worked on breeding wheat with shorter and stronger stalks, which could hold on larger seed heads. Borlaug"s new semi-dwarf, disease-resistant varieties, called Pitic 62 and Penjamo 62, changed the potential yield of Mexican wheat dramatically. By 1963 wheat production in Mexico stood six times more than that of 1944.Green Revolution in IndiaF. During the 1960s, South Asia experienced severe drought condition and India had been importing wheat on a large scale from the United States. Borlaug came to India in 1963 along with Dr. Robert Anderson to duplicate his Mexican success in the sub-continent. The experiments began with planting a few of the high-yielding variety strains in the fields of the Indian AgriculturalResearch Institute at Pusa in New Delhi, under the supervision of Dr. M. S. Swaminathan. These strains were subsequently planted in test plots at Ludhiana, Pantnagar, Kanpur, Pune and Indore. The results were promising, but large-scale success, however, was not instant. Cultural opposition to new agricultural techniques initially prevented Borlaug from going ahead with planting of new wheat strains in India. By 1965, when the drought situation turned alarming, the Government took the lead and allowed wheat revolution to move forward. By employing agricultural techniques he developed in Mexico, Borlaug was able to nearly double South Asian wheat harvests between 1965 and 1970.G. India subsequently made a huge commitment to Mexican wheat, importing some 18,000 tonnes of seed. By 1968, it was clear that the Indian wheat harvest was nothing short of revolutionary. It was so productive that there was a shortage of labour to harvest it, of bull carts to haul it to the threshing floor (打谷场), of jute (黄麻) bags to store it. Local governments in some areas were forced to shut down schools temporarily to use them as store houses.H. United Nation"s Food and Agriculture Organization(FAO) observed that in 40 years between 1961 and 2001, "India more than doubled its population, from 452 million to more than 1 billion. At the same time, it nearly tripled its grain production from 87 million tonnes to 231 million tonnes. It accomplished this feat while increasing cultivated grain acreage (土地面积) a mere 8 percent." It was in India that Norman Borlaug"s work was described as the "Green Revolution".In AfricaI. Africa suffered widespread hunger and starvation through the 70s and 80s. Food and aid poured in from most developed countries into the continent, but thanks to the absence of efficient distribution system, the hungry remained empty-stomach. The then Chairman of the Nippon Foundation, Ryoichi Sasakawa wondered why the methods used in Mexico and India were not extended to Africa. He called up Norman Borlaug, now leading a semi-retired life, for help. He managed to convince Borlaug to help with his new effort and subsequently founded the Sasakawa Africa Association. Borlaug later recalled, "but after I saw the terrible circumstances there, I said, "Let"s just start growing." "J. The success in Africa was not as spectacular as it was in India or Mexico. Those elements that allowed Borlaug"s projects to succeed, such as well-organized economies and transportation and irrigation systems, were severely lacking throughout Africa. Because of this, Borlaug"s initial projects were restricted to developed regions of the continent. Nevertheless, yields of maize, sorghum (高粱) and wheat doubled between 1983 and 1985.Nobel PrizeK. For his contributions to the world food supply, Borlaug was awarded the Nobel Peace Prize in 1970. Norwegian officials notified his wife in Mexico City at 4:00 a. m., but Borlaug had already left for the test fields in the Toluca valley, about 65 km west of Mexico City. A chauffeur (司机) took her to the fields to inform her husband. In his acceptance speech, Borlaug said, "the first essential component of social justice is adequate food for all mankind. Food is the moral right of all who are born into this world. Yet, 50 percent of the world population goes hungry." Green Revolution vs EnvironmentalistsL. Borlaug"s advocacy of intensive high-yield agriculture came under severe criticism from environmentalists in recent years. His work faced environmental and socio-economic criticisms including charges that his methods have created dependence on monoculture crops, unsustainable farming practices, heavy indebtedness among subsistence farmers, and high levels of cancer among those who work with agriculture chemicals. There are also concerns about the long-term sustainability of farming practices encouraged by the Green Revolution in both the developed and the developing world.M. In India, the Green Revolution is blamed for the destruction of Indian crop diversity, drought vulnerability, dependence on agro-chemicals that poison soils but reap large-scale benefitsmostly to the American multi-national corporations. What these critics overwhelmingly advocate is a global movement towards "organic" or "sustainable" fanning practices that avoid using chemicals and high technology in favour of natural fertilizers, cultivation and pest-control programmes.（分数：25.00）(1).Borlaug"s new varieties of wheat have shorter stems and stronger resistance to disease.（分数：2.50）解析：E[解析] 细节辨认题。

I've heard that you and your team have just completed a report on old age.W: That's right. Well, the report basically looks into the various beliefs that people hold about old age and tries to verify them.M: And what do you think your report can achieve?W: We hope that it will somehow help people to change their feelings about old age.The problem is that far too many of us believe that most old people are poor, lonely, and unhappy. As a result, we tend to find old people, as a group, unattractive. And this is very dangerous for our society.M: But surely we cannot escape the fact that many old people are lonely and many are sick.W: No, we can't. But we must also remember that the proportion of such people is no greater among the 60-70 age group than among the 50-60 age group.M: In other words, there is no more mental illness, for example, among the 60s-70s than among the50s-60s.W: Right!M: Are people's mental abilities affected by old age?W: Certain changes do take place as we grow older, but this happens throughout life. These changes are very gradual and happen at different times with different people, but, in general, if you know a person well in his middle age and have seen how he deals with events and problems, you will easily recognize him in an old age.M: So that someone who enjoys new experiences, travel, education, and so on in his middle years will usually continue to do so into old age?W: Exactly.According to the conversation, what do we know about the report?[解析] 对话中女士回答说报告主要调查了人们对老龄期的不同观点，并试图加以验证。
