剑桥雅思8-第三套试题-阅读部分-PASSAGE 1-阅读真题原文部分:READING PASSAGE 1You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1 below.Striking Back at Lightning With LasersSeldom is the weather more dramatic than when thunderstorms strike. Their electrical fury inflicts death or serious injury on around 500 people each year in the United States alone. As the clouds roll in, a leisurely round of golf can become a terrifying dice with death - out in the open, a lone golfer may be a lightning bolt's most inviting target. And there is damage to property too. Lightning damage costs American power companies more than $100 million a year.But researchers in the United States and Japan are planning to hit back. Already in laboratory trials they have tested strategies for neutralising the power of thunderstorms, and this winter they will brave real storms, equipped with an armoury of lasers that they will be pointing towards the heavens to discharge thunderclouds before lightning can strike.The idea of forcing storm clouds to discharge their lightning on command is not new. In the early 1960s, researchers tried firing rockets trailing wires into thunderclouds to set up an easy discharge path for the huge electric charges that these clouds generate. The technique survives to this day at a test site in Florida run by the University of Florida, with support from the Electrical Power Research Institute (EPRI), based in California. EPRI, which is funded by power companies, is looking at ways to protect the United States' power grid from lightning strikes. 'We can cause the lightning to strike where we want it to using rockets, ' says Ralph Bernstein, manager of lightning projects at EPRI. The rocket site is providing precise measurements of lightning voltages and allowing engineers to check how electrical equipment bears up.Bad behaviourBut while rockets are fine for research, they cannot provide the protection from lightning strikes that everyone is looking for. The rockets cost around $1, 200 each, can only be fired at a limited frequency and their failure rate is about 40 per cent. And even when they do trigger lightning, things still do not always go according to plan. 'Lightning is not perfectly well behaved, 'says Bernstein. 'Occasionally, it will take a branch and go someplace it wasn't supposed to go. ' And anyway, who would want to fire streams of rockets in a populated area? 'What goes up must come down, ' points out Jean-Claude Diels of the University of New Mexico. Diels is leading a project, which is backed by EPRI, to try to use lasers to discharge lightning safely - and safety is a basic requirement since no one wants to put themselves or their expensive equipment at risk. With around $500, 000 invested so far, a promising system is just emerging from the laboratory.The idea began some 20 years ago, when high-powered lasers were revealing their ability to extract electrons out of atoms and create ions. If a laser could generate a line of ionisation in the air all the way up to a storm cloud, this conducting path could be used to guide lightning to Earth, before the electric field becomes strong enough to break down the air in an uncontrollable surge. To stop the laser itself being struck, it would not be pointed straight at the clouds. Instead it would be directed at a mirror, and from there into the sky. The mirror would be protected by placing lightning conductors close by. Ideally, the cloud-zapper (gun)would be cheap enough to be installed around all key power installations, and portable enough to be taken to international sporting events to beam up at brewing storm clouds.A stumbling blockHowever, there is still a big stumbling block. The laser is no nifty portable: it's a monster that takes up a whole room. Diels is trying to cut down the size and says that a laser around the size of a small table is in the offing. He plans to test this more manageable system on live thunderclouds next summer.Bernstein says that Diels's system is attracting lots of interest from the power companies. But they have not yet come up with the $5 million that EPRI says will be needed to develop a commercial system, by making the lasers yet smaller and cheaper. 'I cannot say I have money yet, but I'm working on it, ' says Bernstein. He reckons that the forthcoming field tests will be the turning point - and he's hoping for good news. Bernstein predicts 'an avalanche of interest and support' if all goes well. He expects to see cloud-zappers eventually costing 100, 000 each.Other scientists could also benefit. With a lightning 'switch' at their fingertips, materials scientists could find out what happens when mighty currents meet matter. Diels also hopes to see the birth of 'interactive meteorology' - not just forecasting the weather but controlling it. 'If we could discharge clouds, we might affect the weather, ' he says.And perhaps, says Diels, we'll be able to confront some other meteorological menaces. 'We think we could prevent hail by inducing lightning, ' he says. Thunder, the shock wave that comes from a lightning flash, is thought to be the trigger for the torrential rain that is typical of storms. A laser thunder factory could shake the moisture out of clouds, perhaps preventing the formation of the giant hailstones that threaten crops. With luck, as the storm clouds gather this winter, laser-toting researchers could, for the first time, strike back.Questions 1-3Choose the correct letter, A, B, C or D.Write the correct letter in boxes 1-3 on your answer sheet.1 The main topic discussed in the text isA the damage caused to US golf courses and golf players by lightning strikes.B the effect of lightning on power supplies in the US and in Japan.C a variety of methods used in trying to control lightning strikes.D a laser technique used in trying to control lightning strikes.2 According to the text, every year lightningA does considerable damage to buildings during thunderstorms.B kills or injures mainly golfers in the United States.C kills or injures around 500 people throughout the world.D damages more than 100 American power companies.3 Researchers at the University of Florida and at the University of New MexicoA receive funds from the same source.B are using the same techniques.C are employed by commercial companies.D are in opposition to each other.Questions 4-6Complete the sentences below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 4-6 on your answer sheet.4 EPRI receives financial support from………………………….5 The advantage of the technique being developed by Diels is that it can be used……………….6 The main difficulty associated with using the laser equipment is related to its……………….Questions 7-10Complete the summary using the list of words, A-I, below.Write the correct letter, A-I, in boxes 7-10 on your answer sheet.In this method, a laser is used to create a line of ionisation by removing electrons from 7 ………………………….

Left or right?An overview of some research into liberalization: the dominance of one side of the body over the otherACreatures across the animal kingdom have a preference for one foot, eye or even antenna. The cause of this trait, called liberalization, is fairly simple: one side of the brain, which generally controls the opposite side of the body, is more dominant than the other when processing certain tasks. This does, on some occasions, let the animal down: such as when a toad fails to escape from a snake approaching from the right, just because its right eye is worse at spotting danger than its left. So why would animals evolve a characteristic that seems to endanger them?BFor many years it was assumed that liberalization was a uniquely human trait, but this notion rapidly fell apart as researchers started uncovering evidence of liberalization in all sorts of animals. For example, in the 1970s, Lesley Rogers, now at the University of New England in Australia, was studying memory and learning in chicks. She had been injecting a chemical into chicks brains to stop them learning how to spot grains of food among distracting pebbles, and was surprised to observe that the chemical only worked when applied to the left hemisphere of the brain. That strongly suggested that the right side of the chicks brain played little or no role in the learning of such behaviours. Similar evidence appeared in songbirds and rats around the same time, and since then, researchers have built up an impressive catalogue of animal liberalization.CIn some animals, liberalization is simply a preference for a single paw or foot, while in others it appears in more general patterns of behaviour. The left side of most vertebrate brains, for example, seems to process and control feeding. Since the left hemisphere processes input from the right side of the body, that means animals as diverse as fish, toads and birds are more likely to attack prey or food items viewed with their right eye. Even humpback whales prefer to use the right side of their jaws to scrape sand eels from the ocean floor.DGenetics plays a part in determining liberalization, but environmental factors have an impact too. Rogers found that a chick's liberalization depends on whether it is exposed to light before hatching from its egg - if it is kept in the dark during this period, neither hemisphere becomes dominant. In 2004, Rogers used this observation to test the advantages of brain bias in chicks faced with the challenge of multitasking. She hatched chicks with either strong or weak liberalization, then presented the two groups with food hidden among small pebbles and the threatening shape of a fake predator flying overhead. As predicted, the birds incubated in the light looked for foodmainly with their right eye, while using the other to check out the predator. The weakly-lateralized chicks, meanwhile, had difficulty performing these two activities simultaneously.ESimilar results probably hold true for many other animals. In 2006, Angelo Bisazza at the University of Padua set out to observe the differences in feeding behaviour between strongly-lateralized and weakly-lateralized fish. He found that strongly-lateralized individuals were able to feed twice as fast as weakly-lateralized ones when there was a threat of a predator looming above them. Assigning different jobs to different brain halves may be especially advantageous for animals such as birds or fish, whose eyes are placed on the sides of their heads. This enables them to process input from each side separately, with different tasks in mind.FAnd what of those animals who favour a specific side for almost all tasks? In 2009, Maria Magat and Culum Brown at Macquarie University in Australia wanted to see if there was general cognitive advantage in liberalization. To investigate, they turned to parrots, which can be either strongly right- or left-footed, or ambidextrous (without dominance). The parrots were given the intellectually demanding task of pulling a snack on a string up to their beaks, using a co-ordinated combination of claws and beak. The results showed that the parrots with the strongest foot preferences worked out the puzzle far more quickly than their ambidextrous peers.GA further puzzle is why are there always a few exceptions, like left-handed humans, who are wired differently from the majority of the population? Giorgio Vallortigara and Stefano Ghirlanda of Stockholm University seem to have found the answer via mathematical models. These have shown that a group of fish is likely to survive a shark attack with the fewest casualties if the majority turn together in one direction while a very small proportion of the group escape in the direction that the predator is not expecting.HThis imbalance of liberalization within populations may also have advantages for individuals. Whereas most co-operative interactions require participants to react similarly, there are some situations - such as aggressive interactions - where it can benefit an individual to launch an attack from an unexpected quarter. Perhaps this can partly explain the existence of left-handers in human societies. It has been suggested that when it comes tohand-to-hand fighting, left-handers may have the advantage over the right-handed majority. Where survival depends on the element of surprise, it may indeed pay to be different.Questions 27-30Complete each sentence with the correct ending, A-F, below.Write the correct letter, A-F, in boxes 27-30 on your answer sheet.27 In the 1970s, Lesley Rogers discovered that28 Angelo Bisazza’s experiments revealed that29 Magat and Brown’s studies show that30 Vallortigara and Ghirlanda’s research findings suggest thatA liberalization is more common in some species than in others.B it benefits a population if some members have a different liberalization than the majority.C liberalization helps animals do two things at the same time.D liberalization is not confined to human beings.E the greater an animal’s liberalization, the better it is at problem-solving.F strong liberalization may sometimes put groups of animals in danger.Questions 31-35 Complete the summary below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in boxes 31-35 on your answer sheet.Lesley Rogers’ 2004 Experimentliberalization is determined by both genetic and 31__________ influences.

雅思考试模拟试题及答案（阅读部分雅思考试模拟试题及答案(阅读部分）以下是应届毕业生网店铺为同学们收集雅思考试模拟试题及答案(阅读部分)，供大家参考!1.Everyone in a particular society recognizes social roles: father, mother, child, teacher, student, police officer, store clerk, doctor, judge, political leader, and so on. Every culture expects certain types of behavior from people who play certain social roles. Anyone occupying a given position is expected to adopt a specific attitude. A store clerk is expected to take care of customers patiently and politely, and a judge is expected to make wise and fair decisions about laws.Informal social roles are not always easy to recognize, but can be identified with careful research. They are key indicators of a group's health and happiness. Within the family, one informal role is the family hero, the person who defines integrity and upholds family morality. Others are the family arbitrator, the person who keeps the peace, and the family historian, often a grandparent, who relays valuable cultural information that maintains both the family and the larger society. And finally, there is the family friend, the person who provides comfort and companionship to the family members with emotional needs.1.Why does the author mention a store clerk and a judge in paragraph 1?A. To give examples of people who hold positions of respects.B. To explain why social roles are important to a society.C. To illustrate the behavior required of certain social roles.D. To compare the responsibilities of two different occupations.2.Why does the author use the term key indicators in discussing informal social roles?A.To identify the most important type of social roles.B.To explain how to identify informal social rolesC.To point out that informal roles are unique to familiesD.To emphasize the value of informal roles to a group答案:1.C2.D2.The many part of the earth’s atmosphere are linked with the various parts of the earth’s surface to produce a whole---the climate system. Different par ts of the earth’s surface react to the energy of the sun in different ways. For example, ice and snow reflect much of it. Land surfaces absorb solar energy and heat up rapidly. Oceans store the energy without experiencing a significant temperature rise. Thus, the different types of surfaces transfer heat into the atmosphere at different rates.We can view climate as existing in three domains: space, time, and human perception. In the domain of space, we can study local, regional, and global climates. In time, we can look at the climate for a year, a decade, a millennium, and so forth. Finally, we depend on our perceptions of the data, so we must include our own human perception into our model. Human perception must be included if our understanding of climatic processes is to be translated into societal actions. As a society, we make informed choices about how to use the beneficial effects of climate, such as deciding when and where to plant crops. We also make choices about how to minimize the harmful effects of climate---storms, blizzards, and droughts.1.Why does the author discuss different parts of the earth’s surface in paragraph 1?A.To explain why humans live in some parts but not in othersB.To show that the entire earth is made of the same materialsC.To compare how various surfaces transfer heat into the atmosphereD.To describe changes in the earth’s appearance throughout the year.2.According to the author, why must we include human perception in our study of climate?A.We must interpret data and take actions related to climateB.We must create an interesting model of the climate systemC.We must develop an understanding of our environmentD.We must change our traditional ways of studying climate.(思考)3. Read the sentence below and write an essay which will have a minimum of 100 words.Our understanding of climatic processes is to be translated into societal actions.答案：1.C2.A3. veral men have been responsible for promoting forestry asa profession. Foremost was Gifford Pinchot, the father of the professional forestry in America. He was chief of the Forest Service from 1898 until 1910, working with President Theodore Roosevelt to instigate sound conservation practices in forests. Later he was professor of forestry and founder of the Pinchot School of Forestry at Yale University. Another great forester was Dr. Bernard E. Fernow, the first head of the U.S. Forest Service. He organized the first American school of professional forestry at Cornell University.The foresters of today, like Pinchot and Fernow in the past, plan and supervise the growth, protection, and utilization of trees.They make maps of forest areas, estimate the amount of standing timber and future growth, and manage timber sales. They also protect the trees from fire, harmful insects, and disease. Some foresters may be responsible for other duties, ranging from wildlife protection and watershed management to the development and supervision of camps, parks, and grazing lands. Others do research, provide information to forest owners and to the general public, and teach in colleges and universities.1.Why does the author compare Pinchot and Fernow to the foresters of today?A.To describe different philosophies of forestry managementB.To show how the field of forestry has changed in 100 yearsC.To argue for the expansion of university forestry programsD.To introduce the type of work done by professional foresters2.All of the following are mentioned in the passage EXCEPTA.what foresters do besides protecting treesB.how to select a good school of forestryC.people who promoted forestry as a careerD.management of timber and timber sales3. Think about how professors can contribute their wisdom to the public affairs. Write down your contemplations in a essay which have a minimum of 100 words.答案 :1.D2.B4. clothing to declare their membership in a particular social group; however, the rules for what is acceptable dress for that group may change. In affluent societies, this changing of the rules is the driving force behind fashions. By keeping up with fashions, that is, by changing their clothing style frequently butsimultaneously, members of a group both satisfy their desire for novelty and obey the rules, thus demonstrating their membership in the group.There are some interesting variations regarding individual status. Some people, particularly in the West, consider themselves of such high status that they do not need to display it with their clothing. For example, many wealthy people in the entertainment industry appear in very casual clothes, such as the worn jeans and work boots of a manual laborer. However, it is likely that a subtle but important signal, such as an expensive wristwatch, will prevail over the message of the casual dress. Such an inverted status display is most likely to occur where the person’s high status is conveyed in ways other than with clothing, such as having a famous face.1.According to the author, fashions serve all the following purposes EXCEPTA.satisfying an interest in noveltyB.signaling a change in personal beliefsC.displaying membership in a social groupD.following traditional rules2.Why does the author discuss individual status in paragraph 2?A.To state that individuals status is not important in the WestB.To argue that individuals need not obey every fashion ruleC.To contrast the status of entertainers with that of manual laborersD.To explain how high status may involve an inverted status display3. with the booming economy and rising status, Chinese people are beginning to remember the clothing belonging to ourown nation which is called “han fu”(汉服)，and some youth have worn them in some traditional festivals. Please write an essay to express your own thinking.答案：1.B2.DThe war for independence from Britain was a long and economically costly conflict. The New England fishing industry was temporarily destroyed, and the tobacco colonies in the South were also hard hit. The trade in imports was severely affected, since the war was fought against the country that had previously monopolized the colonies’ supply of manufactured goods. The most serious consequences were felt in the cities, whose existence depended on commercial activity. Boston, New York, Philadelphia, and Charleston were all occupied for a time by British troops. Even when the troops had left, British ships lurked in the harbors and continued to disrupt trade.American income from shipbuilding and commerce declined abruptly, undermining the entire economy of the urban areas. The decline in trade brought a fall in the American standard of living. Unemployed shipwrights, dock laborers, and coopers drifted off to find work on farms and in small villages. Some of them joined the Continental army, or if they were loyal to Britain, they departed with the British forces. The population of the New York City declined from 21,000 in 1774 to less than half that number only nine years later in 1783.The disruptions produced by the fighting of the war, by the loss of established markets for manufactured goods, by the loss of sources of credit, and by the lack of new investment all created a period of economic stagnation that lasted for the next twenty years.1.Why does the author mention the fishing industry and the tobacoo colonies?A. to show how the war for independence affected the economyB. to compare the economic power of two different regionsC. to identify the two largest commercial enterprises in AmericaD. to give examples of industries controlled by British forces2. Why does the author mention the population of New York City in paragraph 2?A. to show that half of New York remained loyal to BritainB. to compare New York with other cities occupied during the warC. to emphasize the great short-term cost of the war for New YorkD. to illustrate the percentage of homeless people in New York3. Chinese people had fought for independence from foreign countries for more than 100 years; we had lost lands, powers, resources and lives during that period. Today, China faces a new challenge that how the development can maintain, in other words, how China doesn’t lag behind. Please write an essay to express your ideas.答案：1.A2.CThe discovery of freezing has changed our eating habits more than any other related invention. Because many foods contain large amounts of water, they freeze solidly at or just below 32 degrees Fahrenheit. When we lower the temperature to well below the freezing point and prevent air from penetratingthe food, we retard the natural process of decay that causes food to spoil. Freezing preserves the flavor and nutrients of food better than any other preservation method. When properly prepared and packed, foods and vegetables can be stored in the freezer for one year.Most vegetables and some fruits need blanching before they are frozen, and to avoid this step would be an expensive mistake. The result would be a product largely devoid of vitamins and minerals. Proper blanching curtails the enzyme action, which vegetables require during their growth and ripening but which continues after maturation and will lead to decay unless it is almost entirely stopped by blanching. This process is done in two ways, either by plunging vegetables in a large amount of rapidly boiling water for a few minutes or by steaming them. For steam blanching, it is important that timing begin when the water at the bottom of the pot is boiling. Different vegetables require different blanching times, and specified times for each vegetable must be observed. Under-blanching is like no blanching at all, and over-blanching, while stopping the enzyme action, will produce soggy, discolored vegetables.1.Why does the author mention 32 degrees Fahrenheit?A.To suggest the storage temperature for most foodsB.To identify the freezing point of waterC.To state the correct setting for a freezerD.To give the temperature for blanching2.Why does the author use the term expensive mistake in discussing blanching?A.To state that blanching is expensive but very effectiveB.To warn that not blanching will harm the food’s nutritional valueC.To emphasize the importance of blanching only a few items at a timeD.To show that many people waste food by blanching improperly3. In our daily life, there are a lot of traditional and scientific methods to maintain the foods’ nutrients, please write an essay to introduce the process of one way.答案：1.B2.BThe house style that dominated American housing during the 1880s and 1890s was known as Queen Anne, a curious name for an American style. The name was, in fact, a historical accident, originating with fashionable architects in Victorian England who coined it with apparently no reason other than its pleasing sound. The Queen Anne style was loosely based on medieval structures built long before 1702, the beginning year of Queen Anne’s reign.A distinctive characteristic found in most Queen Anne houses is the unusual roof shape --- a steeply pitched, hipped central portion with protruding lower front and side extensions that end in gables. It is often possible to spot these distinctive roof forms from several blocks away. Another feature of this style is the detailing, shown in the wood shingle siding cut into fanciful decorative patterns of scallops, curves, diamonds, or triangles. Queen Anne houses are almost always asymmetrical. If you draw an imaginary line down the middle of one, you will see how drastically different the right and left sides are, all the way from ground level to roof peak. A final characteristic is the inviting wraparound porch that includes the front door area and then extends around to either the right or left side of the house.Queen Anne houses faded from fashion early in the twentieth century as the public’s taste shifted toward the more modern Prairie and Craftsman style houses. Today, however, Queen Anne houses are favorite symbols of the past, painstakingly and lovingly restored by old-house buffs and reproduced by builders who give faithful attention to the distinctive shapes and detailing that were first popularized more than one hundred years ago.1. Why does the author use the word curious in describing the name of an American style?A.The style was invented before Queen Anne’s reign.B.The name was accidentally misspelled.C.The style was more popular in Victorian England.D.The name did not originate in American.2. The word it in paragraph 1 refers toA. styleB. nameC. accidentD. England3. Which of the following is NOT mentioned as a characteristic feature of Queen Anne houses?A. decorative windowsB. wood shingle exterior wallsC. large porchD. steeply pitched roof4. Which of the following can be inferred from paragraph 2 about the Queen Anne style?A. the Queen Anne style combined several other styles.B. the Queen Anne style had to be built in the city.C. the Queen Anne style was elaborate and ornate.D. the Queen Anne style was not very popular.5. The word buffs in paragraph 3 is closest in meaning toA. expertsB. sellersC. criticsD. painters6. Can you predict the main element which the architects will concern for next generation of house style? Write an essay to give your opinions.答案：1.D2.B3.A4.C5.AOne of the most interesting and distinctive of all uses of language is commentary. An oral reporting of ongoing activity, commentary is used in such public arenas as political ceremonies, parades, funerals, fashion shows and cooking demonstrations. The most frequently occurring type of commentary may be that connected with sports and games. In sports there are two kinds of commentary, and both are often used for the same sporting event. “play-by-play” commentary narrates the sports event, while “color –adding” or “color” commentary provides the audience with pre-event background, during-event interpretation, and post-event evaluation. Color commentary is usually conversational in style and can be a dialogue with two or more commentators.Play-by-play commentary is of interest to linguists because it is unlike other kinds of narrative, which are typically reported in past tense. Play-by-play commentary is reported in present tense. Some examples are “he takes the lead by four” and “she’s in position.” One linguist characterizes radio play-by-play commentary as “a monologue directed at an unknown,unseen mass audience who voluntarily choose to listen…and provide no feedback to the speaker.” It is these characteristics that make this kind of commentary unlike any other type of speech situation.The chief feature of play-by-play commentary is a highly formulaic style of presentation. There is distinctive grammar not only in the use of the present tense but also in the omission of certain element s of sentence structure. For example “Smith in close” eliminates the verb, as some newspaper headlines do. Another example is inverted word order, as in “over at third is Johnson.” Play-by-play commentary is very fluent, keeping up with the pace of the action. The rate is steady and there is little silence. The structure of the commentary is cyclical, reflecting the way most games consist of recurring sequences of short activities---as in tennis and baseball---or a limited number of activity options---as in the various kinds of football. In racing, the structure is even simpler, with the commentator informing the listener of the varying order of the competitors in a “state of play” summary, which is crucial for listeners or viewers who have just tuned in.1.Which of the following statements is true of color commentary?A.It narrates the action of the event in real time, using the present tense.B.It is a monologue given to an audience that does not respond to the speaker.C.It is steady and fluent because it must keep up with the action of the event.D.It gives background on the event, and interprets and evaluates the event.2.Why does the author quote a linguist in paragraph 2?A.To describe the uniqueness of radio play-by-playB.To show how technical sports commentary isC.To give examples of play-by-play commentaryD.To criticize past trends in sports commentary3.It can be inferred from the passage that the author most likely agrees with which of the following statements about sports commentary?A.Color commentary is more important than play-by-play commentaryB.Sports commentators do not need special knowledge of the sport.mentary enhances the excitement and enjoyment of sports.D.Sports commentators should work hard to improve their grammar.答案:1. D2. A3.C。

2021年雅思阅读模拟题精选及答案(卷八)
2021年雅思阅读模拟题精选及答案（卷八）雅思阅读文本：The spectacular aurora light displays that appear in Earth's atmosphere around the north and south magnetic poles were once mysterious phenomena. Now, scientists have data from sat ellites and ground-based observations from which we know that the aurora brilliance is an immense electrical discharge similar to that occurring in a neon sign.To understand the cause of auroras, first picture the Earth enclosed by its magnetosphere, a huge region created by the Earth's magnetic field. Outside the magnetosphere, blasting toward the earth is the solar wind, a swiftly moving plasma of ionized gases with its own magnetic filed.Charged particles in this solar wind speed earthward along the solar wind's magnetic lines of force with a spiraling motion. The Earth's magnetosphere is a barrier to the solar winds, and forces the charged particles of the solar wind to flow around the magnetosphere itself. But in the polar regions, the magnetic lines of force of the Earth and of the solar wind bunch together. Here many of the solar wind's charged particles break through the magnetosphere and enter Earth's magnetic field. They then spiral back and forth between the Earth's magnetic poles very rapidly. In the polar regions, electrons from the solar wind ionizeand excite the atoms and molecules of the upper atmosphere, causing them to emit aurora radiations of visible light.The colors of an aurora depend on the atoms emitting them. The dominant greenish white light comes from low energy excitation of oxygen atoms. During huge magnetic storms oxygen atoms also undergo high energy excitation and emit crimson light. Excited nitrogen atoms contribute bands of color varying from blue to violet. Viewed from outer space, auroras can be seen as dimly glowing belts wrapped around each of the Earth's magnetic poles. Each aurora hangs like a curtain of light stretching over the polar regions and into the higher latitudes. When the solar flares that result in magnetic storms and aurora activity are very intense, aurora displays may extend as far as the southern regions of the United States.Studies of auroras have given physicists new information about the behavior of plasmas,which has helped to explain the nature of outer space and is being applied in attempts to harness energy from the fusion of atoms.雅思阅读题目：1.

Which of the following terms is defined in the passage ?(A) "magnetosphere" (line 6)(B) "electrons" (line 15)(C) "ionize" (line 15)(D) "fusion" (line 29)雅思阅读答案：BCBBCADABAAEconomic EvolutionA Living along the Orinoco River that borders Brazil and Venezuela are the Yanomam people, hunter-gatherers whose average annual income has been estimated at the equivalent of $90 per person per year. Living along the Hudson River that borders New York State and New Jersey are the Manhattan people, consumer traders whose average annual income has been estimated at $36,000 per person per year. That dramatic difference of 400 times, however, pales in comparison to the differences in Stock Keeping Units (SKUs, a measure of the number of types of retail products available), which has been estimated at 300 for the Yanomam and 10 billion for the Manhattans, a difference of 33 million times.B How did this happen? According to economist Eric D. Beinhocker, who published these calculations in his revelatory work The Origin of Wealth (Harvard Business School Press, 2006), the explanation is to be found in complexity theory. Evolution and economics are not just analogous to each other, but they are actually two forms of a larger phenomenon called complex adaptive systems, in which individual elements, parts or agents interact, then process information and adapt their behavior to changing conditions. Immune systems, ecosystems, language, the law and the Internet are all examples of complex adaptive systems.C In biological evolution, nature selects from the variation producedby random genetic mutations and the mixing of parental genes. Out of that process of cumulative selection emerges complexity and diversity. In economic evolution, our material economy proceeds through the production and selection of numerous permutations of countless products. Those 10 billion products in the Manhattan village represent only those variations that made it to market, after which there is a cumulative selection by consumers in the marketplace for those deemed most useful:VHS over Betamax, DVDs over VHS, CDs over vinyl records, flip phones over brick phones, computers over typewriters, Google over Altavista, SUVs over station wagons, paper books over e-books (still), and Internet news over network news (soon).Those that are purchased “survive”and "reproduce" into the future through repetitive use and remanufacturing.D As with living organisms and ecosystems, the economy looks designed—so just as humans naturally deduce the existence of a top-down intelligent designer, humans also (understandably) infer that a top-down government designer is needed in nearly every aspect of the economy. But just as living organisms are shaped from the bottom up by natural selection, the economy is molded from the bottom up by the invisible hand. The correspondence between evolution and economics is not perfect, because some top-down institutional rules and laws are needed to provide a structure within which free and fair trade can occur.But too much top-down interference into the marketplace makes trade neither free nor fair. When such attempts have been made in the past they have failed—because markets are far too complex, interactive and autocatalytic to be designed from the top down. In his 1922 book, Socialism, Ludwig Von Mises spelled out the reasons why, most notably the problem of “economic calculation”in a planned socialist economy. In capitalism, prices are in constant and rapid flux and are determined from below by individuals freely exchanging in the marketplace. Money is a means of exchange, and prices are the information people use to guide their choices. Von Mises demonstrated that socialist economies depend on capitalist economies to determine what prices should be assigned to goods and services. And they do so cumbersomely and inefficiently. Relatively free markets are, ultimately, the only way to find out what buyers are willing to pay and what sellers are willing to accept.E Economics helps to explain how Yanomam-like hunter-gatherers evolved into Manhattan-like consumer-traders. In the Nineteenth century French economist Frederic Bastiat well captured the principle: “Where goods do not cross frontiers, armies will." In addition to being fierce warriors, the Yanomam are also sophisticated traders, and the more they trade the less they fight. The reason is that trade is a powerful social adhesive that creates political alliances. One village cannot go to another village and announce that they are worried about beingconquered by a third, more powerful village—that would reveal weakness. Instead they mask the real motives for alliance through trade and reciprocal feasting. And, as a result, not only gain military protection but also initiate a system of trade that—in the long run—leads to an increase in both wealth and SKUs.F Free and fair trade occurs in societies where most individuals interact in ways that provide mutual benefit. The necessary rules weren't generated by wise men in a sacred temple, or lawmakers in congress, but rather evolved over generations and were widely accepted and practiced before the law was ever written. Laws that fail this test are ignored. If enforcement becomes too onerous, there is rebellion. Yet the concept that human interaction must, and can be controlled by a higher force is universal. Interestingly, there is no widespread agreement on who the "higher force" is. Religious people ascribe good behavior to god's law. They cannot conceive of an orderly society of atheists. Secular people credit the government. They consider anarchy to be synonymous with barbarity. Everyone seems to agree on the concept that orderly society requires an omnipotent force. Yet, everywhere there is evidence that this is not so. An important distinction between spontaneous social order and social anarchy is that the former is developed by work and investment, under the rule of law and with a set of evolved morals while the latter is chaos. The classical liberal tradition of von Mises and Hayeknever makes the claim that the complete absence of top-down rules leads to the optimal social order. It simply says we should be skeptical about our ability to manage them in the name of social justice, equality, or progress.Questions 1-5Do the following statements agree with the information given in Reading Passage 1?In boxes 1-5 on your answer sheet, writeTRUE if the statement is trueFALSE if the statement if falseNOT GIVEN if the information is not given in the passageSKUs is a more precise measurement to demonstrate the economic level of a community.No concrete examples are presented when the author makes the statement concerning economic evolution.Evolution and economics show a defective homolog.Martial actions might be taken to cross the borders if trades do not work.Profit is the invisible hand to guide the market.Questions 6-8Choose the correct letter, A, B, C or D.Write your answers in boxes 6-8 on your answer sheet.6 What ought to play a vital role in each field the economy?A a strict ruleB a smart strategyC a tightly managed authorityD a powerful legislation7-8 Which two of the following tools are used to pretend to ask for union according to one explanation from the perspective of economicsA an official announcementB a diplomatic eventC the exchange of goodsD certain written correspondenceE some enjoyable treatment in a win-win situationQuestions 9-13SummaryComplete the following summary of the paragraphs of Reading Passage, using no more than three words from the Reading Passage for each answer.

雅思考试阅读模拟试题8含答案
雅思考试阅读模拟试题(含答案)
1 There's a dimmer switch inside the sun that causes its brightness to rise and fall on timescales of around 100,000 years—exactly the same period as between ice ages on Earth. So says a physicist who has created a computer model of our star's core.
2 Robert Ehrlich of
George Mason University in Fairfax, Virginia, modelled the effect
of temperature fluctuations in the sun's interior. According to the standard view, the temperature of the sun's core is held constant by the opposing pressures
of gravity and nuclear fusion. However, Ehrlich believed
that slight variations should be possible.
3 He took as his starting point the work of Attila Grandpierre of the
Konkoly Observatory of the Hungarian Academy of Sciences. In , Grandpierre and a collaborator,
Gábor
ágoston,calculated that magnetic fie lds in the
sun's core could produce small instabilities in the solar plasma. These instabilities
would induce localised oscillations
in temperature.
4 Ehrlich's model shows that whilst most of these oscillations cancel each other out,
some reinforce one another and become
long-lived temperature variations. The favoured frequencies allow the sun's core temperature to oscillate a round its average temperature of 13.6 million kelvin in
cycles lasting either 100,000 or
41,000 years. Ehrlich says
that random interactions within the sun's magnetic field could flip the fluctuations from one cycle length to the other.
5 These two timescales are instantly recognisable to anyone familiar with Earth's ice ages: for the past million years, ice ages have occurred roughly every 100,000 years. Before that, they occurred roughly every 41,000 years.
6 Most scientists believe that the ice ages are the result
of subtle changes in Earth's orbit, known as the Milankovitch cycles. One such cycle describes the way Earth's orbit gradually changes shape from a circle to
a slight ellipse and back again roughly every 100,000 years. The theory says this alters the amount of
solar radiation that Earth receives, triggering the ice ages. However,
a persistent problem with this theory has been its inability to explain why the ice ages changed frequency a million years ago.
7 "In Milankovitch, there is certainly no good idea why
the frequency should change from one to another," says Neil Edwards, a climatologist at the Open University in Milton Keynes, UK. Nor is
the transition problem the only one the Milankovitch theory faces. Ehrlich and other critics claim that the temperature variations caused by Milankovitch cycles are simply not big enough to drive ice ages.
8 However, Edwards believes the small changes in solar heating produced by Milankovitch cycles are then amplified by feedback。
