Passage 3As the pace of life continues to increase, we are fast losing the art of relaxation. But relaxation is __1__ for a healthy mind and body.Stress is a natural part of everyday life and there is no way to __2__ it. In fact, it is not the bad thing as it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of __3__ that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such __4__ are obviously prime material for managerial responsibilities. Others lose heart at the first sight of __5__ difficulties. When exposed to stress, in whatever form, we react both physically and __6__. In fact we make choice between “flight or fight” and in more __7__ days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same __8__. It is when such a reaction lasts long, through continued __9__ to stress, that health becomes endangered. Since we cannot __10__ stress from our lives it would be unwise to do so even if we could, we need to find ways to deal with it.Passage 4As is known to all, the organization and management of wages and salaries are very complex. Generally speaking, the Accounts Department is __1__ for calculations of pay, while the Personnel Department is interested in discussions with the employees about pay.If a firm wants to __2__ a new wage and salary structure, it is essential that the firm should decide on a __3__ of job evaluation and ways of measuring the performance of its employees. In order to be __4__, that new pay structure will need agreement between Trade Unions and employers. In job evaluation, all of the requirements of each job are defined in a detailed job description. Each of thoserequirements is given a value, usually in “points”, which are __5__ together to give a total value for the job. For middle and higher management, a special method is used to evaluate managers on their knowledge of the job, their responsibility, and their __6__ to solve problems. Because of the difficulty in measuring management work, however, job grades for managers are often decided without __7__ to an evaluation system based on points.In attempting to design a pay system, the Personnel Department should __8__ the value of each job with these in the job market. __9__, payment for a job should vary with any differences in the way that the job is performed. Where it is simple to measure the work done, as in the works done with hands, monetary encouragement schemes are often chosen, for __10__ workers, where measurement is difficult, methods of additional payments are employed.Passage 5Americans are proud of their variety and individuality, yet they love and respect few things more than a uniform. Why are uniforms so __1__ in the United States?Among the arguments for uniforms, one of the first is that in the eyes of most people they look more __2__ than civilian（百姓的）clothes. People have become conditioned to __3__ superior quality from a man who wears a uniform.The television repairman who wears a uniform tends to __4__ more trust than one who appears in civilian clothes. Faith in the __5__ of a garage mechanic is increased by a uniform. What an easier way is there for a nurse, a policeman, a barber, or a waiter to __6__ professional identity（身份）than to step out of uniform? Uniforms also have many __7__ benefits. They save on other clothes. They save on laundry bills. They are often more comfortable and more durable than civilian clothes.Primary among the arguments against uniforms is their lack of variety and the consequent loss of __8__ experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it,without __9__, until retirement. When people look alike, they tend to think, speak, and act __10__, o n the job at le a st.Passage 6Britain is not just one country and one people; even if some of its inhabitants think so. Britain is, in fact, a nation which can be divided into several __1__ parts, each part being an individual country with its own language, character and cultural __2__. Thus Scotland, Northern Ireland and Wales do not claim to __3__ to “England” because their inhabitants are not __4__ “English”. They are Scottish, Irish or Welsh and many of them prefer to speak their own native tongue, which in turn is __5__ to the others.These cultural minorities(少数民族) have been Britain’s original inhabitants. In varying degrees they have managed to __6__ their national characteristics, and their particular customs and way of life. This is probably even truer of the __7__ areas where traditional life has not been so affected by the __8__ of industrialism as the border areas have been. The Celtic races are said to be more emotional by nature than the English. An Irish temper is legendary. The Scots could rather __9__ about their reputation for excessive thrift and prefer to be remembered for their folk songs and dances, while the Welsh are famous for their singing. The Celtic __10__ as a whole produces humorous writers and artists, such as the Irish Bernard Shaw, the ScottishPassage 8Psychologists take opposing views of how external rewards, from warm praise to cold cash, affect motivation and creativity. Behaviorists, who study the relation between actions and their consequences, argue that rewards can __1__ performance at work and school. Cognitive( 认识派的) researchers, who study various aspects of mental life, maintain that rewards often destroy creativity by encouraging dependence on __2__ and gifts from others.A coeducational(男女合校的) school offers children nothing less than a tree version of society in miniature(缩影). Boys and girls are given the 1 to get to know each other, to learn to live together from their earliest years. They are put in a position where they can compare themselves with each other in terms of 2 ability, athletic achievement and many of the extracurricular activities which are part of school life. What a practical 3 it is (to give just a small example) to be able to put on a school play in which the male parts will be taken by boys and the female parts by girls! What nonsense coeducation makes of the argument that boys are cleverer than girls or vice versa. When 4 , boys and girls are made to feel that they are a race apart. In a coeducational school, everything falls into its 5 place.The greatest contribution of coeducation is 6 the healthy attitude to life it encourages. Boys don’t grow up believing that women are 7 creatures. Girls don’t grow up imagining that men are romantic heroes. Years of living together at school remove illusions of this kind. The awkward stage of adolescence brings into sharp focus some of the physical and 8 problems involved in growing up. These can better be 9 in a coeducational environment. When the time comes for the pupils to leave school, they are fully prepared to 10 society as well-adjusted adults. They have already had years of experience in coping with many of the problems that face men and women.Passage 13The anthropologist (人类学家) Clifford Geertz defines culture as a “historically transmitted pattern of meanings embodied in symbols by 1 of which men can communicate, perpetuate and develop their own knowledge about and attitudes towards life.”Why is it important that you 2 about other cultures? There are a number of reasons. Some may do it 3 because they find fascinating the different ways that people think, speak, act, evaluate, and communicate. But let me assume that you are a more pragmatic sort of person, and are 4 in the “cash value” of a course like this — apart, that is, from the grade you will receive at the end of it. What is a class like this good for? Let me make a couple of suggestions on how what you learn in this class may prove 5 to you in the future:Business: Geert Hofstede’s excellent book on culture is 6 not primarily out of academic theory, but out of his study of the practical problems faced by one particular modern corporation (IBM), which exists across national and cultural 7 . In the world we live in, understanding 8 in general and also specific individual cultures in particular can make the difference between success and failure in the global market and economy.Politics and Diplomacy: If your career goal involves anything that relates to international politics and diplomacy, then understanding other cultures is 9 .Neighbors: If none of these previous factors 10 you, then you can just look at this class as a lesson in good neighborliness in the global village.Passage 14A pioneering study into the effects of a mother’s fat intake during pregnancy on her child’s health when he or she grows up is being launched at the University of Southampton.The research will investigate whether the type and amount of fat a mother eats during pregnancy 1 the risk of heart disease, 2 high blood pressure, in her child when he or she reaches adulthood.Although the link between high fat diets and high blood pressure is well known, there has been 3 research into the connection between a woman’s diet and her child’s risk of hypertension (高血压).The study, which is 4 by the British Heart Foundation, is led by Dr Graham Burdge, British Heart Foundation Professor of Cardiovascular Science.The award of this 5 grant is part of a ￡3.5 million boost for heart research in the UK by the British Heart Foundation. The charity’s special grants are made to fund research into the causes, prevention, 6 and treatment of heart disease, the UK’s biggest killer.Dr Burdge says, “The type and amount of fat in our diet has 7 during the past 50 years. Pregnant women 8 the same diet as the rest of us, but we know very little about the 9 of these changes in dietary (饮食的) fat on the development and future health of their children. We hope that the 10 of this study will help to develop recommendations for pregnant women about how much fat they should eat and what types of fat they should avoid.”Passage 15Major retailers and car manufacturers have slashed (削减) their marketing budgets in the six months to October, 2008, as the financial crisis has taken its toll, while supermarkets have __1__advertising spending in a battle to prove that they offer the most ___2__ prices.According to new research undertaken for The Daily Telegraph by Nielsen Media Research, in the six months to September 30, 2008, Marks & Spencer’s advertising spend fell 20.3 pc to ￡25.3 m, __3___ with the same period in 2007.While the retailer has spent heavily on a campaign __4__ celebrities in the past two years, it is understood to be cutting back on celebrity spending in 2009. The retailer is, however, still the UK’s 25th largest spender on advertising, __5__ being at 17th place in the six months to September 30, 2007.Car manufacturers have also significantly ___6__ back on marketing spending, believed to be a result of the financial crisis. According to Nielsen, Ford spent ￡26.6m in the six months to September 30, 2008, down 21pc from the same period last year. Vauxhall also ___7__ spending by 15.6pc in the period to ￡26.5m.For supermarkets, however, a significant increase in advertising spending, it appears, is a ___8___ as they seek to woo (追求) increasingly price __9__ customers. The leading supermarkets have __10__ an aggressive price war in the past six months as consumers have been faced with news of higher food prices.Passage 16Teddy bears have been around since 1902. The teddy bear came to being when President Theodore Roosevelt refused to 1 a black bear held captive by his hunting party. Also worth noting is that President Roosevelt’s refusal to shoot this captive bear became a very popular political cartoon by Cliff Barryman.A Brooklyn shopkeeper was 2 by the cartoon. The shopkeeper then asked President Rosevelt for 3 to name a toy bear “Teddy”. Thus became the creation of the teddy bear.It is also worth 4 that the teddy bear was born in Germany between 1902 and 1903.The first teddy bears did not have cuddly faces or smiles, in fact, the first teddy bears had expressions which could best be described as 5 . Teddy bears were also quite stiff, the 6 arms and legs and soft, plush bodies came much later.Now teddy bears are still the number one item to give babies as their first toy, the prize to win your girl on your first date, and most 7 , the toy of choice for law enforcement to give to children in sad, unsafe situations to help them calm down and feel safe.The market for collectible teddy bears has seen significant 8 in the last several years. A collectible teddy bear is very different than the typical store bought teddy that you might give a child. The industry 9 collectible teddy bears as hard, not floppy, and fully jointed (meaning arms, legs, and head are moveable). The artists however, also determine collectibles. Steiff teddy bears and others have a very high collectible 10 .Passage 17Hungry prehistoric hunters, not climate change, drove elephants to extinction during the Pleistocene era, new research suggests.At least 12 kinds of elephants 1 to roam the African, Eurasian, and American continents. Today, only two 2 of elephants are left in South Asia and sub-Saharan Africa. One theory for this dramatic demise holds that rapid climate shifts at the end of the most recent major ice age, some 10,000 years ago, 3 vegetation and broke up habitats, causing the death of those unable to adapt to the new conditions. Another 4 blames prehistoric humans, whose improved weapons and hunting techniques allowed them to wipe out whole herds of elephants.To help 5 the debate, archaeologist Todd Surovell of the University of Wyoming, Laramie, and colleagues tested two assumptions. If humans caused the elephant and mammoth extinctions, Surovell reasoned, the timing of the die-offs in 6 regions should match human expansion into those regions. On the contrary, if the extinction was 7 to climate change, elephants should remain in regions 8 colonized by humans and would only begin to die off once climate change occurred.The team tested both theories by analyzing where and when elephants were killed. In all, the study included 41 archaeological sites on five continents. The researchers found that, as humans 9 out of Africa, they left a trail of dead elephants behind them. The creatures disappear from the fossil record of a region once it became colonized by humans. Modern elephants survived in refuges 10 to humans, such as tropical forests, says Surovell.Passage 18There have been claims that warming on Mars and Pluto are proof that the recent warming on Earth is caused by an increase in solar activity, and not by greenhouses gases. But we can say with 1 that, even if Mars, Pluto or any other planets have warmed in recent years, it is not due to 2 in solar activity.The Sun's energy output has not increased since direct 3 began in 1978. If increased solar output really was 4 , we should be seeing warming on all the planets and their moons, not just Mars and Pluto.Our solar system has eight planets, three dwarf planets and quite a few moons with at least a 5 atmosphere, and thus a climate of sorts. Their climates will be 6 by local factors such as orbital variations, changes in reflectance (反射率) and even 7 eruptions, so it would not be surprising if several planets and moons turn out to be warming at any one time.However, given that a year on Mars is 8 two Earth years long, and that a year on Pluto lasts for 248 Earth years, it is rather early to start 9 conclusions about long-term climate trends on the outer bodies of the Solar System.What do we know? Images of Mars suggest that between 1999 and 2005, some of the frozen carbon dioxide that 10 the south polar region turned into gas. This may be the result of the whole planet warming.。

Passage OnePop means popular, and a pop singer is supposed to work very hard to become popular. He must either give the public what they already want, or he must find a new way of singing that will H(attract) their attention. Even when he has succeeded, and his G(record) are sold everywhere, he cannot E(relax) _. Then he must work harder than ever to _B(remain)_ popular, because there are always younger singers trying to become famous and to steal some of the popularity.The life of a successful pop singer isn't at all easy. He can only relax when he is A(alone) , because everything he does is watched and reported in the special newspaper, written for the fans. The fans are the most D(important) people in the world for the singer. They buy his records, they go to his conceits, and they make him rich and famous. But they can be very L(annoying) too. Sometimes the tans become so crazy that they do anything to get a "souvenir". They steal handkerchiefs, they tear off buttons, and they even cut off pieces of the unfortunate singer's hair. Many singers have been forced to hide, and some have not been so I(lucky) as to escape being stripped(剥夺)practically C (naked)(裸体) by their fans. A pop singer has to spend a lot of money on clothes, because he must always look smart, or, at any rate, M(different)_. He must have an expensive car. And--most important –he must always keep smiling for the benefit of his public.Passage TwoThe United States is full of A(automobiles汽车). There are still many families without cars, but some families have two or even more. However, cars are used for more than pleasure. They are _H(necessary)_ part of life.Cars are used for B(business) . They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their I(products) . Farmers have to drive into the city in order to get supplies.Sometimes small children must be driven to school. In some cities school F(BUSES) are used only when children live more than a mile from the school. When the children are too young to walk that J(far)_, their mothers _G(take)_ turns driving them to school. One mother drives on Mondays, taking her own children and neighbors’ children as well. Another drives on Tuesdays, another on Wednesdays, and so on. This is called forming a car pool(联盟). Men also _C(form) car pools, with three or four men taking turns driving to the place where they all work.More car pools should be formed in order to put fewer automobiles on the road and to use less D(gasoline)_. Parking is a great problem, and so is the _E（traffic）_ in and around cities. Too many cars are being driven. Something will have to be done about the use of cars.Passage ThreeDon't try kicking the tires(轮胎) on a very modem and strange car developed by students at Coventry University. Not only does the car have no tires, it has no B(steering掌舵) wheel（车轮，方向盘）, either.The Coventry Concept(概念) Car, as it is called is a __C (completely)__ new design that looks more like a snail(蜗牛) than an automobile. No working model（模型）, or functional（功能的）form of the _D(vehicle车辆) exists yet, but its designers recently introduced a life-sized model and explained how a real one would work.Electric motors would move rapidly undulating pad (形成波浪状气垫) A（underneath底层的）the car; moving the vehicle in any direction at speeds up to 480 km per hour. The motion would be a much faster way of L （crawling速率）, the way snails move. (Muscles in the bottom of a snail's flat foot _K(contract)__ in waves that push the snail along the ground.)Steering of the snail car would be _H(handled有把柄的) automatically by an onboard computer, which would receive signals from orbiting satellites. Those signals would help guide the snail car along a preprogrammed _ J(_route)_,Even the car's color could be computer-controlled, the student designer suggested. Instead of a painted-out _I(appearance)_, the snail car would sport (显示) an electronically sensitive film that changes color according to its _G(surroundinf)_ .Passage FourNot all language is verbal. Some of our J(communication) occurs(发生) without words. We often use our entire(全部) bodies for communication. We may raise our eyebrows to C(indicate) surprise. Perhaps we nod our heads to show that we agree with something. There are hundreds of nonverbal(非口头) H(signals信号，标志) that can be used to communicate. These signals are part of language, and they are G(governed管理支配) by rules in the same way that our spoken language is. For this reason, people who speak different languages often use different nonverbal signals as well.In addition to verbal communication and the type of nonverbal communication discussed above, there are other message I(systems) that we use to communicate. When we speak to some people, we may stand very A(close)them, while we may stand far away from other people. Use of space, then, is a way we can communicate(B(relationship) another person. The way we _D(dress)so communicate for us. The person who wears dirty jeans and a T-shirt communicates a different E(attitude) from a person who wears neat trousers and an attractive shirt. We can even use time to communicate. The person who is on time for an F(appointment) shows a different attitude from the person who is an hour late does. Can you think of other message systems we use in communication?Passage FiveHow can English teachers accelerate(加快|) the language teaming of their students? One way is to teach students how to learn more effectively and efficiently. Learning strategies(策略) are ―procedures or _A(techniques)_ that learners can use to facilitate(促进) a learning task.‖ B(instructing指导) students of English in learning strategies can help them become better learners. In addition, skill in using learning strategies assists students in becoming G(independent) , confident learners. Finally, students become more I(motivated) as they begin to understand the relationship between their use of strategies and success in learning English.Students need to develop an awareness of the learning process and strategies that lead to success. Students who C(reflect反映) on their own thinking are more likely to engage in planning how to proceed with a learning task, monitoring their own performance on an ongoing basis, finding solutions to problems _F(encountered遇到)_, and evaluating themselves upon task completion. These activities may be difficult for students __J(accustomed使习惯)_ to having a teacher who solves all their learning problems and is the O (sole基础，触底，唯一)_ judge of their progress.Teachers need to encourage students to rely more on themselves. Because learning strategies are mental N(processes)__ with few observable manifestations, teachers need to find ways to make the strategies as concrete as possible. When students are able to use the strategies their teachers have taught them, and to do so without prompting, then they need to _ M(explore) new strategies, new applications, and new opportunities for self-regulated learning.Passage SixAn unusual cooperation(合作) between the local university and other education providers in East Anglia has seen the C (establishment) of Norwich's new Learning Shop. At the city center shop, local people can look through booklets and leaflets to find out about learning opportunities G(ranging)__ from evening classes to postgraduates degrees. Skilled staff is on hand to give _I(accurate)_ information about courses and training in the region.More than 11,000 people have visited the shop since it opened in 1997. The majority of inquiries have been about courses in further education, but 17 percent have _ H(related)__ to higher education in general. Customer feedback J(confirms)_ how valuable the resource is. A woman’s F(comment评论，意见) is typical: ―It's a brilliant idea—less daunting than going to the different institutions.‖ A seller told us: ―This really gives you hope you can get back into something.‖Fellow _E(institutions体系) are welcome to set up exhibitions and events at the shop: to date, these have included poetry readings, a recorder concert and D(numerous许多的) exhibitions and displays. The shop is staffed by two advisers and other colleagues from the fellow institutions in the region. Speaking at the "Norwich as a Learning City" _B(conference会议，协商) . Prof. Mike Campell at the local university, said the first barrier to learning was lack of information. The Learning Shop aims to break down that _ A(barrier)) .There is a popular belief among parents that schools are no longer interested in spelling. No school I have taught in has ever K(ignored) spelling or considered it unimportant as a basic skill. There are, however, vastly different ideas about how to teach it, or how much G(priority优先) it must be given over general language development and _F(writing)_ability. The problem is how to encourage a child to express himself freely and E(tend) in writing without holding him back with the complexities of spelling.If spelling becomes the only focal point of his teacher's interest, clearly a bright child will be likely to "play safe". He will A(confidently)_ to write only words within his spelling range, choosing to B(avoid) adventurous(危险) language. That's why teachers often encourage the early use of dictionaries and pay attention to C(content内容目录满足) rather than technical ability.I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling errors and your writing is illegible（难于辨认的）." It may have been a sharp criticism批评of the pupil's technical abilities in writing, but it was also a sad reflection on the teacher who had omitted遗漏省去to read the essay, which contained some beautiful expressions of the child's deep feelings. The teacher was not wrong to draw attention to the D(errors) , but if his priorities had M (centered居中的) on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more motivation to seek _N(improvement) .Passage EightJust like children, deer often cross British roads to get to the other side. But the cost is the deer's life. At night, _ E(speeding)_ cars hit and kill the animals. Now foresters are using natural animal D(instinct本能)_ to prevent dangerous crossings.In England, the British Forestry Commission has B(installed(安装) thousands of glowing red ―wolf eyes‖ along woodland roads. The eyes are actually reflectors (反射镜), _C(plastic)__ bars like the red reflectors on your bike. The ten-centimeter long bars are fixed on top of posts, with only these signs directed towards the woods rather than the roads.When cars speed by, light rays from car headlights reflect off the reflectors' shining surface and I(flash) into the woods. Deer are instantly(马上) _A(scared) by the wolf eyes—even though wolves haven't _J(hunt) deer in Britain or even lived there for a hundred years!Scientists think the glowing(灼热的) light K(imitate模仿) the "eye shine" of nightly beasts. (Y ou've probably seen eye shine on cats. Mirror-like cells in the eyes N(reflect) some light that hits them.) The deer must not have ―forgotten‖ that a wolf can run up to 72 km per hour in M(hot) pursuit, or can sniff deer out from 2.4 km away.Passage NineIt was once believed that being overweight was healthy, but nowadays few people subscribe to this viewpoint. While many people are fighting the battle to reduce weight studies are being conducted concerning the _A(appetite食欲)__ and how it is controlled by both emotional and biochemical factors. Some of the _B(conclusion))__ of these studies may give insights into how to deal with weight problems. For example, when severe hundred people were asked about their eating habits in times of stress, 44 percent said they reacted to stressful situations by eating. Further investigations with both humans and animals indicated that it is not food which F（relieves）tension but rather the act of C(chewing) .A test in which subjects were blindfolded showed that obese (肥胖的)people have a keener sense of taste and crave (渴望) more flavorful food than non-obese people. When deprived of the variety and _D(intensity强度强烈) of tastes, obese people are not satisfied and consequently eat more to E(fulfill) this need. Blood G(samples)__ taken from people after they were shown a picture of food revealed that overweight people reacted with an increase in blood insulin (胰岛素), a chemical (associate) J with appetite. This did not happen to average-weight people.Exercise has been (recommended)I as an important part of a weight-loss program. However, it has been found that mild exercise, such as using the stairs instead of the H(elevator)电梯, is better in the long run than taking on a strenuous program, such as jogging, which many people find difficult to continue over long periods of time and which also increases appetite.Passage T enThe first practical pen with reservoir is credited to Lewis Edson Waterman, a 45-year-old American insurance broker in 1884. The story goes that he was getting ready to sign a E(vital与..竞争)_ contract on a building site and had bought a new pen for the (occasion)K feeling that it would _ L(create) a good impression and be more convenient for the circumstances than the more usual dip nib pen. The C(contract) was on the table, and the pen was in fee client's hand. Once, twice and even a third time the pen refused to write and then it made an ink blot on the important paperwork. Mr. Waterman returned to his office in all M(haste赶快)_, obtained a fresh contract and returned to the site—a (rival比得上)A_ broker had beaten him to it and the client had signed a contract with the competitor.Waterman refused to be caught out again in like fashion and having an inventive mind designed his own pen and commenced to produce them in his brother's （workshop车间）O_. His design was based upon the physical force of capillarity where air replace the ink used giving a smooth, even, blot free flow. His idea was patented in 1884 but he continued to sell insurance while B（manufacturing）just a few hundreds pens per year. However, Waterman saw the _D(benefits) of advertising and sales increased rapidly. Gold nibs were H(obtains获得) from New Y ork and in 1900 a factory was built in Montreal, Canada to make the pens.。

Turkish authorities have just sunk something a little different than a ship, and it wouldn't normally ever touch water, an Airbus A300. The hollowed-out A300 was __27__ of everything potentially harmful to the environment and sunk off the Aegean coast today. Not only will the sunken plane __28__ the perfect skeleton for artificial reef growth, but authorities hope this new underwater attraction will bring tourists to the area.The plane __29__ a total length of 54 meters, where experienced scuba divers will __30__ be able to venture through the cabin and around the plane's __31__ Aydin Municipality bought the plane from a private company for just under US $ 100, 000, but they hope to see a return on that __32__ through the tourism industry. Tourism throughout Turkey is expected to fall this year as the country has been the __33__ of several deadly terrorist attacks. As far as sunken planes go, this Airbus A300 is the largest __34__ sunk aircraft ever.Taking a trip underwater and __35__ the inside of a sunken A300 would be quite an adventure, and that is exactly what Turkish authorities are hoping this attraction will make people think. Drawing in adventure seekers and experienced divers, this new artificial Airbus reef will be a scuba diver's paradise （天堂）.（二）A.acquiredB.adaptationsC.brutalD.deliberatelyE.expressedF.extendsG.habitats H.humble I.imageJ.literally K.refined L.revolvesM.speculate N.structure O.thriveJust because they can't sing opera or ride a bicycle doesn't mean that animals don't have culture. There's no better example of this than killer whales. As one of the most __26__ predators （食肉动物）, killer whales may not fit the __27__ of a cultured creature. However, these beasts of the sea do display a vast range of highly __28__ behaviors that appear to be driving their genetic development.The word "culture" comes from the Latin "colere," which __29__ means "to cultivate." In other words, it refers to anything that is __30__ or learnt, rather than instinctive or natural. Among human populations, culture not only affects the way we live, but also writes itself into our genes, affecting who we are. For instance, having spent many generations hunting the fat marine mammals of the Arctic, the Eskimos of Greenland have developed certain genetic __31__ that help them digest and utilize this fat- rich diet, thereby allowing them to __32__ in their cold climate.Like humans, killer whales have colonized a range of different __33__ across the globe, occupying every ocean basin on the planet with an empire that __34__ from pole to pole. As such, different populations of killer whales have had to learn different hunting techniques in order to gain the upper hand over their local prey （猎物）. This, in turn, has a major effect on their diet, leading scientists to __35__ that the ability to learn population-specific hunting methods could be driving the animals, genetic development.（三）A.bidB.contrastC.deputyD.dominanceE.fleetsF.knotsG.legislation H.migrated I.replaceJ.represent K.restrictive L.rewardM.significant N.sponsor O.transmittedThe center of American automobile innovation has in the past decade moved 2,000 miles away. It has __26__ from Detroit to Silicon Valley, where self-driving vehicles are coming to life.In a __27__ to take production back to Detroit, Michigan lawmakers have introduced __28__ that could make their state the best place in the country, if not the world, to develop self-driving vehicles and put them on the road."Michigan's __29__ in auto research and development is under attack from several states and countries which desire to __30__ our leadership in transportation.

Americans view five hours of TV each day, and while we know that spending so much time sitting 36 can lead to obesity (肥胖症) and other diseases, researchers have now quantified just how 37 being a couch potato can be.In an analysis of data from eight large 38 published studies, a Harvard-led group reported in the Journal of the American Medical Association that for every two hours per day spent channel 39 , the risk of developing Type 2 diabetes(糖尿病) rose 20% over 8.5 years, the risk of heart disease increased 15% over a 40 , and the odds of dying prematurely 41 13% during a seven-year follow-up. All of these 42 are linked to a lack of physical exercise. But compared with other sedentary(久坐的) activities, like knitting, viewing TV may be especially 43 at promoting unhealthy habits. For one, the sheer number of hours we pass watching TV dwarfs the time we spend on anything else. And other studies have found that watching ads for beer and popcorn may make you more likely to 44 them.Even so, the authors admit that they didn’t compare different sedentary activities to 45 whether TV watching was linked to a greater risk of diabetes, heart disease or early death compared with, say, reading.（五）A.announcingB.beneficialC.challengesmitmentponentF.contestsG.critically H.develop I.distributingJ.enhance K.entitled L.potentialM.properly N.qualified O.retainThe U.S. Department of Education is making efforts to ensure that all students have equal access to a quality education.

Kids with more than one older autistic sibling had an even higher risk of the disorder: 32%.The 39 suggest that genes play a key role in autism risk. But they also hint that other environmental factors 40 by siblings, like influences in the womb（子宫）, may be important as well.On the 41 of the findings, the researchers recommend that doctors closely 42 younger siblings of autistic children to pick up any early signs of the disorder, 43 an unusually large head or delayed language development and communication skills.

大学英语四级_选词填空_技巧篇
大学英语四级选词填空技巧篇1）阅读选项，词性分类仍然要―先题后文在定位‖，但这里―先题‖不是要找关键词，而是要先对15个选项―辨性‖仔细阅读选项，根据词性把每个单词进行分类归纳。
如名词、动词、形容词、副词、介词、连词各有几个选项。
动词归类要细分为v，ved, ving。
因为一个空可以填动词，但填原形还是过去式还是ing形式要自己根据语法判断。
2）细读首句，抓住中心首先要抓住文章首句，迅速找到文章的主题词或主题。
和完型填空一样，一般文章第一句不设空格，以便让读者知道本文的相关主题词或主题。
3）瞻前顾后，谨慎选择根据文章前后的语法关系判断应填入的词性，大大缩小选择范围。
当一个空可以填入好几个相同词性的词时，则根据上下文逻辑意义；如果均能说得通时，要注意近义辨析。
或留到最后，等范围缩小到最小时再轻松收尾。
即传统阅读所说的，首遍不行无所谓，文章看完再收尾。
解题技巧1）首先要辨性（辨别词性）a. 不认识的单词看词缀（见后面附表）b. 认识的单词要注意词性的单一性和多样性比如：must，most均可做名词do the most you canc. 动词归类要细分为v，ved, ving。
因为一个空可以填动词，但填原形还是过去式还是ing 形式要自己根据语法判断。
甚至动词分词形式还可以做定语。
2）一个单词有多个词性时，要在不同分类中都标出。
3）如果选项中出现一组近义词或反义词时，往往有一个是干扰选项，它注重考察的是词汇的精确理解，要求考生分析清楚其细微的区别。
4）如何判断原文空缺处所需单词的词性：①动词：a）前后都是名词短语，中间一般为动词（时态看前后文）。
b) 一个句子有且只有一个谓语动词c）一个完整的句子之后再跟逗号，后面一般是非谓语动词短语。
②名词：a. 名词主要做主语、宾语。
b. 形容词或名词都可以修饰名词例：The hot, humid (潮湿的) air over the ocean causes severe ___49___ thunderstorms.（49可能是形容词，也可能是名词修饰thunderstorms）c. 限定词（the, this, that, a, my之类）后必有名词d. 谓语动词前必有名词或名词性质的主语e. 介词后面必有名词③. 副词修饰形容词或动词附录：四级常用后缀1. 名词后缀1)-or/er/ess/crat/cis:做某件事情或职业的人或物：worker, debtor2)-acy, 表示―性质，状态，境遇‖ democracy, accuracy, diplomacy3)-ance, -ence表示―性质，状况，行为，过程，总量，程度‖ importance, diligence, difference, obedience4)-ancy, -ency, 表示―性质，状态，行为，过程‖ frequency, urgency, efficiency,5)-bility, 表示―动作，性质，状态‖ possibility, flexibility, feasibility,6)-dom, 表示―等级，领域，状态‖ freedom, kingdom, wisdom7)-hood, 表示"资格，身份, 年纪，状态" childhood, manhood, falsehood8)-ion, -sion, -tion, -ation, -ition, 表示―行为的过程，结果，状况‖ action, solution, conclusion, destruction, expression_r, correction9)-ism, 表示―制度，主义，学说，信仰，行为‖ socialism, criticism, colloquialism, heroism10)-ity, 表示―性质，状态，程度‖ purity, reality, ability, calamity11)-ment, 表示―行为，状态，过程，手段及其结果‖ treatment, movement, judgment, punishment, argument12)-ness, 表示―性质，状态，程度‖四级选词填空解题技巧发表于：2009-6-12 浏览：112 次来源：华浦华浦（Chinatop）教育集团是中国首家致力于提供升学、求职、晋升的教育培训、就业推荐的大型综合性现代教育培训集团，秉承―一站成就梦想‖的办学理念，更以其培养出众多出色的学员而成为全国著名培训机构。

大学英语四级选词填空专项练习Passage 1What is it about Americans and food? We love to eat, but we feel 1 about it afterward. We say we want only the best, but we strangely enjoy junk food. We’re 2 with health and weight loss but face an unprecedented epidemic of obesity(肥胖). Perhaps the 3 to this ambivalence(矛盾情结) lies in our history. The first Europeans came to this continent searching for new spices but went in vain. The first cash crop(经济作物) wasn’t eaten but smoked. Then there was Prohibition, intended to prohibit drinking but actually encouraging more 4 ways of doing it.The immigrant experience, too, has been one of inharmony. Do as Romans do means eating what “real Americans” eat, but our nation’s food has come to be 5 by imports—pizza, say, or hot dogs. And some of the country’s most treasured cooking comes from people who arrived here in shackles.Perhaps it should come as no surprise then that food has been a medium for the nation’s defining struggles, whether at the Boston Tea Party or the sit ins at southern lunch counters. It is integral to our concepts of health and even morality whether one refrains from alcohol for religious reasons or evades meat for political 6 But strong opinions have not brought 7 . Americans are ambivalent about what they put in their mouths. We have become 8 of our foods, especially as we learn more about what they contain.The 9 in food is still prosperous in the American consciousness. It’s no coincidence, then, that the first Thanksgiving holds the American imagination in such bondage(束缚). It’s what we eat—and how we 10 it with friends, family, and strangers—that help define America as a community today.A. answerB. resultC. shareD. guiltyE. constantF. definedG. vanishH. adaptedI. creativeJ. beliefK. suspicious L. certainty M. obsessed N. identify O. ideals Passage 2After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll(死亡人数) could have been much worse. More than 60 people died in this earthquake. By comparison, and earthquake of similar __1__ that shook America in 1998 claimed 25,000 victims.Injuries and deaths were __2__ less in Los Angeles because the quake occurred at 4:31 a.m. On a holid ay, when traffic was light on the city’s highway. In addition, __3__ made to the construction codes in Los Angeles during the last 20 years have strengthened the city’s buildings and highways, making them more __4__ to quakes.In the past, making structures quake-resist-ant meant firm yet __5__ materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to __6__ the impact of ground vibrations. The most __7__ designs givebuildings brains as well as concrete and steel supports, called smart buildings, the structures respond like living organisms to an earthquake’s vibrations. When ground shakes and the building tips forward, the computer would __8__ the building to shift in the opposite direction.

The way you go about purchasing an article or a service can actually 1 you money or can add to the cost. Take the 2 example of a hairdryer. If you are buying a hairdryer, you might think that you are making the 3 buy if you choose one whose look you like and which is also the cheapest 4 price. But when you get it home you may find that it takes twice as long as a more expensive 5 to dry your hair.The cost of the electricity plus the cost of your time could well make your hairdryer the most expensive one of all.So what principles should you 6 when you go out shopping? If you keep your home, your car or any valuable 7 in excellent condition, y ou’ll be saving money in the long run. Before you buy a new 8 , talk to someone who owns one .If you can, use it or borrow it to check it suits your particular purpose.

The real questions are: How much of the warming is our fault, and are we 1 to slow the devastation by controlling our insatiable 2 for fossil fuels?Global warming can seem too 3 to worry about, or too uncertain-something projected by the same computer 4 that often can’t get next week’s weather right. On a raw winter day you might think that a few degrees of warming wouldn’t be such a bad thing anyway. And no doubt about it: Warnings about 5 change can sound like an environmentalist scare tactic, meant to force us out of our cars and restrict our lifestyles.Comforting thoughts, perhaps. Unfortunately, however, the Earth has some discomforting news. From Alaska to the snowy peaks of the Andes the world isheating up right now, and fast. Globally, the 6 is up 1°F over the past century, but some of the coldest, most remote spots have warmed much more. The results aren’t pretty. Ice is 7 , rivers are running dry, and coasts are 8 , threatening communities.The 9 are happening largely out of sight.

They have developed a hitlist of our main fears: natural resources are 1 out? the population is ever growing, leaving less and less to eat? species are becoming 2 in vast numbers, and the planet’s air and water are becoming ever more polluted.But a quick look at the facts shows a different picture. First, energy and other natural resources have become more 3 n ot less so, since the book ‘The Limits to Growth’ was published in 1972 by a group of scientists. Second, more food is now produced per 4 of the world’s population than at any time in history. Fewer people are 5 . Third, although species are indeed becoming extinct, only about 0.7% of them areexpected to disappear in the next 50 years, not 25~50%, as has so often been 6 . And finally, most forms of environmental pollution either appear to have been 7 , or are transient –associated with the early stages of industrialization and therefore best cured not by restricting economic growth, but by 8 it. One form of pollution –the release of greenhouse gases that causes global warming –does appear to be a phenomenon that is going to extend well into our future, but its total impact is unlikely to 9 a devastating (令人心神不安的) problem. A bigger problem may well turn out to be an inappropriate response to it.Yet opinion polls suggest that many people nurture the belief that environmental standards are declining and some factors seem to cause this disjunction between 10 and reality.A) pose B) exaggerated C) accelerating D) extinct E) existF) perception G) wealthy H) magnified I) starving J) headK) running L) predicted M) abundant N) conception O) reducing Passage 7EI NIno is name given to the masterious and often unpredictable change in the climate of the world.This strange ___1_____happens every five to eight years.It starts in the PAacific Ocean and is thought to be caused by a failure in the trade winds(信风)，which affects the ocean currents driven by these winds.

英语四级真题之选词填空1Part III Reading Comprehension (40 minutes)Section ADirections：In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.For decades, Americans have taken for granted the XXXX development of new technologies. The innovations(创新)XXXX opment during World War II and afterwards were(36)_____ to the prosperity of the nation in the second half of the 20th century. Those innovations, upon which virtually all aspects of(37)_____ society now depend, were possible because the United States then(38)_____ the world in mathematics and science education. Today, however, despite increasing demand for workers with strong skills in mathematics and science, the(39)_____ of degrees awarded in science, math, and engineering are decreasing.The deeling in degree production in what are called the STEM disciplines(science, technology, engineering, andmath.)seems to be(40)_____related to the comparatively weak performance by U.S. schoolchildren on international assessments of math and science. Many students entering college have weak skills in mathematics. According to the 2005 report of the Business Higher Education Forum, 22 percent of college freshmen must take remediat(补习的)math(41)_____, and less than half of the students who plan to major in science or engineering(42)_____complete a major in those fields.The result has been a decrease in the number of American college graduates who have the skills, (43)_____ in mathematics, to power a workforce that can keep the country at the forefront(前言)of innovation and maintain its standard of living. With the(44)_____ performance of American students in math and science has come increased competition from students from other countries that have strongly supported education in these areas.

However, the answers provided by Japanese preschools are not the ones Americans expected to find. In most Japanese preschools, surprisingly little emphasis is put on academic instruction. In one investigation, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents (答问卷者)listed “to give children a good start academically”as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese schools do not teach reading, writing, and mathematics, but rather skills such as persistence, concentration, and the ability to function as a member of a group. The vast majority of young Japanese children are taught to read at home by their parents.In the recent comparison of Japanese and American preschool education, 91 percent of Japanese respondents chose providing children with a group experience as one of their top three reasons for a society to have preschools. Sixty-two percent of the more individually oriented (强调个性发展的)Americans listed group experience as one of their top three choices. An emphasis on the importance of the group seen in Japanese early childhood education continues into elementary school education.Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools. Some Japanese parents believe that if their young children attend a university-based program, it will increase the children‘s chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens.16.We learn from the first paragraph that many Americans believe ________.A) Japanese parents are more involved in preschool education than American parentsB) Japan‘s economic success is a result of its scientific achievementsC) Japanese preschool education emphasizes academic instructionD) Japan‘s higher education is superior to theirs17.Most Americans surveyed believe that preschools should also attach importance to ________.A) problem solvingB) group experienceC) parental guidanceD) individually-oriented development18.In Japan‘s preschool education, the focus is on ________.A) preparing children academicallyB) developing children‘s artistic interestsC) tapping children‘s potentialD) shaping children‘s character19.Free play has been introduced in some Japanese kindergartens in order to ________.A) broaden children‘s horizonB) cultivate children‘s creativityC) lighten children‘s study loadD) enrich children‘s knowledge20.Why do some Japanese parents send their children to university -based kindergartens?A) They can do better in their future studies.B) They can accumulate more group experience there.C) They can be individually oriented when they grow up.D) They can have better chances of getting a first-rate education.英语四级真题之选词填空3Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Resilience Is About How You Recharge, Not How You Endure[A] As constant travelers and parents of a 2-year-old, we sometimes fantasize about how much work we can do when one of us gets on a plane, undistracted by phones, friends, or movies. We race to get all our ground work done: packing, going through security, doing a last-minute work call, calling each other, then boarding the plane. Then, when we try to have that amazing worksession in flight, we get nothing done. Even worse, after refreshing our email or reading the same studies over and over, we are too exhausted when we land to soldier on with (继续处理) the emails that have inevitably still piled up.[B] Why should flying deplete us? We’re just sitting there doing nothing. Why can’t we be tougher, more resilient (有复原力的) and determined in our work so we can accomplish all of the goals we set for ourselves? Based on our current research, we have come to realize that the problem is not our hectic schedule or the plane travel itself; the problem comes from a misconception of what it means to be resilient, and the resulting impact of overworking.[C] We often take a militaristic, “tough” approach to resilience and determination like a Marine pulling himself through the mud, a boxer going one more round, or a football player picking himself up off the ground for one more play. We believe that the longer we tough it out, the tougher we are, and therefore the more successful we will be. However, this entire conception is scientifically inaccurate.[D] The very lack of a recovery period is dramatically holding back our collective ability to be resilient and successful. Research has found that there is a direct correlation between lack of recovery and increased incidence of health and safety problems. And lack of recovery—whether by disrupting sleep with thoughts of work or having continuous cognitive arousal by watching our phones—is costing our companies $62 billion a year in lost productivity.[E] And just because work stops, it doesn’t mean we are recovering. We “stop” work sometimes at 5pm, but then we spend the night wrestling with solutions to work problems,talking about our work over dinner, and falling asleep thinking about how much work we’ll do tomorrow. In a study just released, researchers from Norway found that 7.8% of Norwegians have become workaholics(工作狂). The scientists cite a definition of “workaholism” as “being overly concerned about work, driven by an uncontrollable work motivation, and investing so much time and effort in work that it impairs other important life areas.”[F] We believe that the number of people who fit that definition includes the majority of American workers, which prompted us to begin a study of workaholism in the U.S. Our study will use a large corporate dataset from a major medical company to examine how technology extends our working hours and thus interferes with necessary cognitive recovery, resulting in huge health care costs and turnover costs for employers.[G] The misconception of resilience is often bred from an early age. Parents trying to teach their children resilience might celebrate a high school student staying up until 3am to finish a science fair project. What a distortion of resilience! A resilient child is a well-rested one. When an exhausted student goes to school, he risks hurting everyone on the road with his impaired driving; he doesn’t have th e cognitive resources to do well on his English test; he has lower self-control with his friends; and at home, he is moody with his parents. Overwork and exhaustion are the opposite of resilience and the bad habits we acquire when we’re young only magnify when we hit the workforce.[H] As Jim Loehr and Tony Schwartz have written, if you have too much time in the performance zone, you need more time in the recovery zone, otherwise you risk burnout. Gathering your resources to “try hard” requires burning ener gy in order toovercome your currently low arousal level. It also worsens exhaustion. Thus the more imbalanced we become due to overworking, the more value there is in activities that allow us to return to a state of balance. The value of a recovery period rises in proportion to the amount of work required of us.[I] So how do we recover and build resilience? Most people assume that if you stop doing a task like answering emails or writing a paper, your brain will naturally recover, so that when you start a gain later in the day or the next morning, you’ll have your energy back. But surely everyone reading this has had times when you lie in bed for hours, unable to fall asleep because your brain is thinking about work. If you lie in bed for eight hours, you may have rested, but you can still feel exhausted the next day. That’s because rest and recovery are not the same thing.[J] If you’re trying to build resilience at work, you need adequate internal and external recovery periods. As researchers Zijlstra, Cro pley and Rydstedt write in their 2014 paper: “Internal recovery refers to the shorter periods of relaxation that take place within the frames of the work day or the work setting in the form of short scheduled or unscheduled breaks, by shifting attention or changing to other work tasks when the mental or physical resources required for the initial task are temporarily depleted or exhausted. External recovery refers to actions that take place outside of work—e.g. in the free time between the work days, and du ring weekends, holidays or vacations.” If after work you lie around on your bed and get irritated by political commentary on your phone or get stressed thinking about decisions about how to renovate your home, your brain has not received a break from high mental arousal states. Our brains need a rest as much as our bodies do.[K] If you really want to build resilience, you can start by strategically stopping. Give yourself the resources to be tough by creating internal and external recovery periods. Amy Blankson describes how to strategically stop during the day by using technology to control overworking. She suggests downloading the Instant or Moment apps to see how many times you turn on your phone each day. You can also use apps like Offtime or Unplugged to create tech free zones by strategically scheduling automatic airplane modes. The average person turns on their phone 150 times every day. If every distraction took only 1 minute, that would account for 2.5 hours a day.[L] In addition, you can take a cognitive break every 90 minutes to charge your batteries. Try to not have lunch at your desk, but instead spend time outside or with your friends—not talking about work. Take all of your paid time off, which not only gives you recovery periods, but raises your productivity and likelihood of promotion.[M] As for us, we’ve started using our plane time as a work-free zone, and thus time to dip into the recovery phase. The results have been fantastic. We are usually tired already by the time we get on a plane, and the crowded space and unstable internet connection make work more challenging. Now, instead of swimming upstream, we relax, sleep, watch movies, or listen to music. And when we get off the plane, instead of being depleted, we feel recovered and ready to return to the performance zone.36. It has been found that inadequate recovery often leads to poor health and accidents.37. Mental relaxation is much needed, just as physical relaxation is.38. Adequate rest not only helps one recover, but alsoincre ases one’s work efficiency.39. The author always has a hectic time before taking a flight.40. Recovery may not take place even if one seems to have stopped working.41. It is advised that technology be used to prevent people from overworking.42. Contrary to popular belief, rest does not equal recovery.43. The author has come to see that his problem results froma misunderstanding of the meaning of resilience.44. People’s distorted view about resilience may have developed from their upbringing.45. People tend to think the more determined they are, the greater their success will be.英语四级真题之选词填空4Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold orflu (流感)may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That‘s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. Although theflu and common cold have many similarities, there are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症)， a rare but serious condition of the liver and central nervous system.There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.11.According to the author, knowing the cause of the misery will help ________.A) shorten the duration of the illnessB) the patient buy medicine over the counterC) the patient obtain cheaper prescription drugsD) prevent people from catching colds and the flu12.We learn from the passage that ________.A) one doesn‘t need to take any medicine if he has a cold or the fluB) aspirin should not be included in over-the-counter medicines for the fluC) delayed treatment of the flu will harm the liver and central nervous systemD) over-the-counter drugs can be taken to ease the misery caused by a cold or the flu13.According to the passage, to combat the flu effectively, ________.A) one should identify the virus which causes itB) one should consult a doctor as soon as possibleC) one should take medicine upon catching the diseaseD) one should remain alert when the disease is spreading14.Which of the following symptoms will distinguish the flu from a cold?A) A stuffy nose.B) A high temperature.C) A sore throat.D) A dry cough15.If children have flu-like symptoms, their parents ________.A) are advised not to give them aspirinB) should watch out for signs of Reye syndromeC) are encouraged to take them to hospital for vaccinationD) should prevent them from mixing with people running a fever英语四级真题之选词填空5Lead deposits, which accumulated in soil and snow during the 1960‘s and 70‘s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly.A study published recently in the journal Nature shows thatair-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的)snow were declining.In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分)the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline.Many scientists had believed that the lead would stay in soil and snow for a longer period.The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990 The forest environment processed and redistributed the lead faster than the scientists had expected.Scientists say both studies demonstrate that certain parts of the ecosystem (生态系统)respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.21.The study published in the journal Nature indicates that ________.A) the Clean Air Act has not produced the desired resultsB) lead deposits in arctic snow are on the increaseC) lead will stay in soil and snow longer than expectedD) the US is the major source of lead pollution in arctic snow22.Lead accumulation worldwide decreased significantly after the use of unleaded gas in the US ________.A) was discouragedB) was enforced by lawC) was prohibited by lawD) was introduced23.How did scientists discover the source of lead pollution in Greenland?A) By analyzing the data published in journals like Nature and Ambio.B) By observing the lead accumulations in different parts of the arctic area.C) By studying the chemical elements of soil and snow in Northeastern America.D) By comparing the chemical compositions of leaded gasoline used in various countries.24.The authors of the Ambio study have found that ________.A) forests get rid of lead pollution faster than expectedB) lead accumulations in forests are more difficult to deal withC) lead deposits are widely distributed in the forests of the USD) the upper layers of soil in forests are easily polluted by lead emissions25.It can be inferred from the last paragraph that scientists ________.A) are puzzled by the mystery of forest pollutionB) feel relieved by the use of unleaded gasolineC) still consider lead pollution a problemD) lack sufficient means to combat lead pollution 下载全文。

第一篇关于减肥Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line throughthe center. You may not use any of the words in the bank more than once.Questions 47 to 56 are based on the following passage.Perhaps like most Americans you have some extra pounds to 47 . You may even have tried a fad diet or two, but found yourself right back where you started. The key to weight loss isregular 48 activity. And surprisingly, you don't have to give up eating or make the gym your second home to see long-term, 49 effects.You body needs a certain amount of energy to maintain basic 50 such as breathing, blood circulation and digestion. The energy required to keep your organs functioning is referred to as the resting or basal metabolic rate.Any time you are active, 51 energy is required. It is obtained from glycogen and fat stored in the blood, liver, and muscles. The key to losing weight is to draw on the fat rather than on the carbohydrate reserves.Which of the two energy sources you use depends on the intensity and 52 of your activity. The higher the intensity, the more your body will pull from the stored carbohydrates. The lowerthe intensity, the more your body will 53 on fat as its fuel.Aerobic exercise is most 54 for weight loss. When you perform aerobic activities you 55 contract large muscle groups such as your legs and arms. Walking, running, rollerblading, swimming, dancing, and jumping jacks are all forms of aerobic activity.Surprisingly, if your aerobic activity is low to moderately intense and of long duration, youwill burn more fat than if you had 56 in a short burst of high-intensity exercise. In short, a brisk 30-minute walk will burn fat while a 100-yard sprint will burn glycogen.[A] positive [B]additional [C] duration [D]effective [E] shed[F] physical [G] food [H] functions [I]participated [J] rely[K] cut [L] repeatedly [M] uses [N] little [O] obvious47.
