托福阅读真题第191篇HabitatSelection（答案文章最后）
托福阅读真题第191篇HabitatSelection（答案文章最后）Habitat SelectionParagraph 1：Researchers who study habitat selection have proposed various models for the process. Marine biologist Peter F. Sale hypothesized the existence of a simple mechanism of habitat selection in fish that is based on levels of exploratory behavior. Sense organs monitor specific stimuli in the environment and send a summation of pertinent stimuli back to central-nervous-system centers, which regulate the amount of exploration. As the constellation of cues approaches some optimum level, exploratory behavior ceases and the animal stays where it is.1. According to paragraph 1, all of the following are processes that occur during exploratory behavior EXCEPT: O A favorable combination of cues are gathered.O Sense organs detect and record stimuli in the surrounding area.O Sense organs receive further directions from the central nervous system.O The central nervous system receives a summary of stimuli from the sense organs.Paragraph 2：An alternative hypothesis is that an animal has a cognitive map of the ideal habitat and that its behavior is goal directed. However, working with a species of surgeonfish, Sale tested juveniles in laboratory tanks with various water depths and bottom covers under which fish could hide. Exploration time was least in the tank with shallow water and bottom cover and highest in the tank with shallow water and no bottom cover. In choice tests and field observations, most fish preferred shallowareas with bottom cover. Thus, Sale concluded, there is no need to suggest the inheritance of complex cognitive maps and goal-directed behaviors; rather, the animal simply moves around more in an unsuitable habitat and less in a suitable one.2. In paragraph 2, why does the author discuss Sale’s research with a species of surgeonfish?O To demonstrate how animals distinguish suitable habitats from unsuitable onesO To give an example of an animal that shows little or no exploratory behavior during habitat selectionO To challenge the hypothesis that animals have complex cognitive maps of their ideal habitat that guide their habitat selectionO To provide evidence that fish prefer areas that are shallow and have covering under which to hideParagraph 3：Sale’s model still does not explain how the animal “knows” what is suitable and what is not, or how stimuli from multiple cues are integrated. Nor does it explain the role of photoperiod (the duration of the animal’s daily exposure to sunlight) in the response of dark-eyed juncos to photographs of their natural habitat. These wild-caught birds were presented a choice of viewing one of two 35-millimeter color slides showing different habitats. Birds kept in the lab under a winter photoperiod of nine hours of light and fifteen hours of darkness preferred (spent more time in front of) slides of their southern winter habitat. After day length was increased to fifteen hours of light and nine hours of darkness, the birds’ viewing preferences shifted to the northern summer habitat.3. According to paragraph 3, Sale’s model of habitat selection is unable to explain which of the following?O Why dark-eyed juncos’ interest in a particular habitat changes with the duration of daylight they are exposed to O Why the environment suitable for dark-eyed juncos in the winter differs from the environment suitable for them in the summerO Why only some species of animals respond to photographs of their natural habitatsO Why birds studied in the lab behave differently than birds in the wild do4. Paragraph 3 supports which of the following statements about dark-eyed juncos?O The habitat preference of dark-eyed juncos changes with the amount of daylight present.O Wild-caught dark-eyed juncos do not recognize photographs of their own habitat.O Dark-eyed juncos choose their habitat based on seasonal temperatures.O Artificial light affects dark-eyed juncos’ choice of habitat differently than does natural sunlight.Paragraph 4： Social cues may also affect choice of habitat. Large juncos (usually males) dominate smaller individuals (usually females and juveniles) in wintering flocks. Biologist Ellen Ketterson explained the finding that females usually migrate farther south than males by hypothesizing that subordinate birds are forced to migrate farther to avoid competing with dominants. In their lab study, researchers E. Roberts and Peter Weigl found that during the short days (stimulating winter), small subordinate juncos showed the strongest preference for winter scenes.5. According to paragraph 4, what reason has been suggested for why female juncos often migrate farther souththan do male juncos?O To avoid the colder temperatures farther northO To provide safer habitats for their juvenilesO To avoid having to compete with malesO To find habitats having the longest daysParagraph 5：Risk of predation and competition are other factors that may affect habitat use. Hairy-footed gerbils live in vegetated islands in a sea of sand in the Namib Desert of southern Africa. Habitat use was determined by tracks in the sand and by how quickly they gave up feeding at stations containing seeds mixed with sand. Gerbils preferred sites around bushes or grass clumps to open areas and were more active on new-Moon nights than on full-Moon nights. They also gave up feeding at seed trays sooner in open areas and on full-Moon nights. These differences were likely caused by greater risk of predation in open areas and when the Moon was full. When striped mice, a close competitor of the gerbil, were removed, gerbils increased foraging activity, especially in the grass clumps.6. According to paragraph 5, why do hairy-footed gerbils prefer to feed in bushes and grass clumps?O There is more food available there.O There is less competition there from striped mice.O There is more shade there from the heat of the desert.O There is less danger there of being harmed by a predator.Paragraph 6：The immediate cues to which animals respond when selecting a habitat may not be the same as the ultimate factors that have brought about the evolution of the response. For example, the blue tit, a European bird, lives in oak woodlands where most of its preferred food is found. But the blue tit establishes its territory each year before leaves and caterpillars(its staple food) have even appeared, so it must be using some other cue, such as the shape of the trees, to select its habitat. In fact, we know little about the signals that animals respond to when choosing their habitat. And in migratory species, it is not even clear when in the life cycle a choice of habitat is made. One study found that breeding sites may be selected in late summer or fall before migration, rather than in the spring, as is usually assumed.7. According to paragraph 6, which of the following is true about habitat selection by the blue tit?O It selects a habitat having the tallest trees.O It selects a habitat where there are no caterpillars to eat the leaves.O It selects its territory each year in spring.O It selects its habitat before its preferred food appears in the area.8. Paragraph 6 supports which of the following statements about scientists’ knowledge of habitat selection?O Scientists have successfully identified most of the immediate factors that animals respond to in choosing their habitats.O Scientists have determined the seasons in which most animal species choose their habitats.O Scientists know that evolution has led animals to ignore cues in their environment when choosing habitats.O Scientists still have much to learn about the cues to which animals respond in choosing their habitats.Paragraph 3：Sale’s model still does not explain how the animal “knows” what is suitable and what is not, or how stimuli from multiple cues are integrated. Nor does it explain the role ofphotoperiod (the duration of the animal’s daily exposure to sunlight) in the response of dark-eyed juncos to photographs of their natural habitat. These wild-caught birds were presented a choice of viewing one of two 35-millimeter color slides showing different habitats. Birds kept in the lab under a winter photoperiod of nine hours of light and fifteen hours of darkness preferred (spent more time in front of) slides of their southern winter habitat. ■After day length was increased to fifteen hours of light and nine hours of darkness, the birds’ viewing preferences shifted to the northern summer habitat.Paragraph 4：■Social cues may also affect choice of habitat. ■Large juncos (usually males) dominat e smaller individuals (usually females and juveniles) in wintering flocks. ■Biologist Ellen Ketterson explained the finding that females usually migrate farther south than males by hypothesizing that subordinate birds are forced to migrate farther to avoid competing with dominants.

0308 托福试题阅读（ 55minutes）Question 1-11If food is allowed to stand for some time, itputrefies .When the putrefied materialis examined microscopically ,it is found to be teeming withbacteria. Where do thesebacteria come from , since they are not seen in fresh food? Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 ) generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structurespresent in air closely resemble the microorganisms seen in putrefying materials .He did(10)this by passing air through guncotton filters, the fibers of which stop solid particles. Afterthe guncotton was dissolved in a mixture of alcohol and ether,the particles that it hadtrapped fell to the bottom of the liquid and were examined ona microscope slide .Pasteurfound that in ordinary air these exists a variety of solidstructures ranging in size from0.01 mm to more than 1.0 mm .Many of these bodies resembledthe reproductive(15)s tructures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedfrom the organized bodies present in the air .He postulated thatthese bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary forspontaneous generation and that the air inside the sealed flaskwas affected in some way(25)by heating so that it would no longer support spontaneousgeneration. Pasteur constructed a swan-necked flask in which putrefying materials could he heated to boiling, but aircould reenter. The bends in the neck preventedmicroorganisms from getting in the flask.. Material sterilized insuch a flask did not putrefy.1,What does the passage mainly discuss?(a)Pasteur’ s influence on the development of the microscope.(b)The origin of the theory of spontaneous generation .(c)The effects of pasteurization on food.(d)Pasteur’ s argumentnstagaithe theory of spontaneous generation . 2,The phrase “ teeming with ” in line 2 is closest in meaning to (a)full of(b)developing into(c)resistant to(d)hurt by3,Which of the following questions did the theory of spontaneous generation attempt to answer?(a)What is the origin of the living organisms are seen on some food?(b)How many types of organisms can be found on food?(c)What is the most effective way to prepare living organisms for microscopic examination?(d)How long can food stand before it putrefies?4,The word“ resemble” in line 9 is closest in meaning to(a)benefit from(b)appear similar to(c)join together with(d)grow from5,The purpose of the“ guncotton” mentioned in paragraph 2 was to (a)trap particles for analysis (b)slow theprocess of putrefaction (c)increase the airflowto the microscopic slide (d)aid the mixing ofalcohol and ether6,The author mention “ 1.0mm” in line 14 in describing the(a)thickness of a layer of organisms that was deposited on an object(b)diameter of the fibers that were in the guncotton filters(c)thickness of the microscope slides that were used(d)size of the particles that that were collected7.The word “ postulated ” in line 19 is closest in meaning to(a)analyzed(b)doubted(c)persuaded(d)suggested8.The objects that Pasteut removed from the air in his experimentwere remarkable because they were(a)primarily single-celled organisms(b)no different from objects found in putrefyingmaterials (c)fairly rare(d)able to live in a mixture of alcohol and ether9.The word“ it” in line 22 refers to(a)a nutrient solution(b)a glass flask(c)boiling(d)spontaneous generation10.According to paragraph 3,proponents of spontaneous generation believed that which of the following was important forthe process to succeed ?(a)A sealed container(b)Fresh air(d)The presence of nutrients11.It can be inferred from paragraph 3 that Pasteur employed a swam-necked flask to(a)store sterilized liquids for use in futureexperiments (b)prevent heat from building up in asolution (c)disprove a criticism of his conclusions(d)estimate the number of organisms in a liter of airQuestions 12-20In the early decades of the United States ,the agrarian movement promoted the farmeras society ’heros. In the minds of agrarian thinkers andwriters ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,whichended in 1865 ,was the age of(5 )the farmer in the United States .Agrarianphilosophers ,represented most eloquently byThomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a goodsociety, their political virtue ,and their Superior morality .Andvirtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10)all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15)launched exploring expeditions into prospective farmlands in the West .In addition ,government trade policies facilitated the exporting of agriculturalFor their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20)more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops andpure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunningrapidity .But farmers responded(25)less to the expectations of agrarians and governmentinducements than to growing market opportunities .European demand for food from the United States seemed insatiable .

In general, the realm ’ s soils also reflect the broad environmental partitioninginto “ humid America ”and “ arid America. ”Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher in acid content) noralkaline(higher in salt content).fertilization is necessary to achieve the desired level of neutrality between the```two. Arid America ’soils are typically alkaline and must be fertilized back towardneutrality by adding acidic compounds. Although many of these dryland soils, particularlyin the Great Plains, are quite fertile, European settlers learned over a century ago that(10)water is the main missing ingredient in achieving their agricultural potential. In the1970’ s,certain irrigation methods were perfected and finally provided a real opportunityto expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15)and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but theenormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20)the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as one crosses the(25)border into the Northeast United States. As one proceedstoward the Southeast, broadleaf vegetation becomes dominant.Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.```21 What aspect of North America does the passage mainly discuss?(A)The wide variety of climates(B)Soil types and vegetation patterns(C)Improved irrigation methods and the expansion of agriculture(D)The change in precipitation patterns22 The word“ spawn” in line 1 is closest in meaning to(A)distinguish(B)eliminate(C)protect(D)create23 The word“ partitioning” in line 2 is closest in meaning to(A)division(B)modification(C)opening(D)circulating24 According to the passage, acidic soils tent to be associated with(A) a high salt content(B)an increase in farming(C)large amounts of rain(D)glacial meltwater25 The word“ enhanced” in line 13 is closest in meaning to(A)implied(B)increased(C)indicated(D)informed26 How did glacial meltdown affect the soil in North America?(A)It redistributed the soil types(B)It added salt to the soil(C)It made the soil more neutral in content(D)It added minerals to the soil27 The phrase“regionalizationthis scheme” in line 19 refers to the(A)movements of glacial deposits```(B)patterns of natural vegetation(C)human modification of the North American environment(D)distinction between humid America and arid America28 The word“ transition” in line 23 is closest in meaning to(A)elevation(B)change(C)advantage(D)condition29 The passage supports which of the following statements?(A)Arid America is not necessarily characterized by the presenceof deserts(B)Most of Canada and the northeastern United States consists ofshort-grass prairies wherever natural vegetation has not been modified by humans(C)The accumulation of loess is primarily the result of irrigation(D)Glaciation removed the fertile layer of soil from much of theMississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second),the human eye will not reactin time to see the object. A photographic emulsion---that is, alight-sensitive coating on photographic film, paper, or glass--- will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used to capture high-speed movement on film as wellas to correct deficiencies of the normal surrounding lighting.Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When thebag was ignited, the metal burned with an intense flash. A contemporary observer reported(10)that “ this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd poses. ”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of beingignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’arliest.Inthetype, the metal (15)was separated from the oxygen by a thin glass bulb. Theflash was fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignitedspontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygendifluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to a white-hot emissionof visible light. The smoke particles are so small that they cool rapidly; but since they are white, theycontribute to the brilliance by reflecting the light from their still-glowing neighbors. A slightly bigger form of the metal will burn for a longer time.30 What does the passage mainly discuss?(A)The history of the photoflash(B)Theories about how the eye reacts to light(C)The technology of modern photography(D)The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A)recording of an image on film(B)generation of artificial light(C)creation of a photographic emulsion(D)human eye to react to light32 According to the passage, an advantage of using a photoflash is that it(A)can produce repeated bursts of light(B)intensities colors in photographs(C)is short enough not to bother human eyes(D)supplements existing lighting33 The word“ ignited” in line 9 is closestniingmeato(A)set on fire(B)cut into(C)opened(D)shaken34 Which of the following phrases is defined in paragraph 1?(A) ” appreciable period” (line 1)(B) ” photographic emulsion” (line 3)(C)” high-speed movement” (line 5)(D)” odd poses” (line 11)35 The word“ evolution” in line 12 is closest in meaning to(A)publicity(B)adoption(C)development(D)manufacture36 The function of the glass in the first flashbulbs was to(A)produce the spark that initiated the flash(B)magnify the light produced by the flash(C)protect the photographer from the heat of the flash(D)keep the metal and oxygen apart before the flash37 The word“ it” in line 18 refers to(A)oxygen(B)battery(C)wire(D)current38 The word“ momentarily” in line 20 is closest iningmeanto(A)effortlessly(B)briefly(C)electronically(D)gradually39 According to the passage, the white color of the smokeparticles generated by a flashbulb contributes to(A)rapid cooling(B)bright illumination(C)electrical conductivity(D)intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A)thicker wire(B)more oxygen(C)thinner glass(D)continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’ sThe. Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. Theyconcentrated onthe play of light over objects, people, and nature, breaking up seemingly solid surfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected lightin all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and thenmoving indoorsto complete the work form memory.(10) Some of the Impressionists painting’ methods were affected by technologicaladvances. For example, the shift from the studio to the openair was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finishtheir paintings on the spot.(15)Impressionism acquired its name not from supporters but from angry art lovers whofelt threatened by the new painting. The term “ Impressionism ” was born in 1874,whena group of artists who had been working together organizedan exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintingsexhibited was one called(20)Impression:Sunrise, by Claude Monet(1840-1926),Viewedthrough hostile eyes,Monet ’ spainting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet s title, art critics’extended the term “ Impressionism to”the entire exhibit. Inresponse, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25)From then until 1886 Impressionism had all the zeal of a“ church” , as the painter Renoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A)The impact of some artists’ resistance to the fast pace of life(B)The differences between two major styles of art(C)A technological advance in the materials used by artists(D) A group of artists with a new technique and approach to art42 The word“ depict” in line 2 is closest in meaning to(A)reorganize(B)deform(C)represent(D)justify43 According to the passage, which of the following was one ofthe distinguishing characteristics of Impressionist painting?(A)The emphasis on people rather than nature scenes(B)The way the subjects were presented from multiple angles(C)The focus on small solid objects(D)The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A)They began by making sketches of their subjects(B)They painted their subjects out-of-doors(C)They preferred to paint from memory(D)They used subjects drawn from modern life45 The word“ advent” in line 12 is closest in meaning to(A)achievement(B)acceptance(C)arrival(D)advantage46 The exhibition of paintings organized in 1874 resulted in allof the following EXCEPT(A)attracting attention from the public(B)a negative reaction from the press(C)an immediate demand for the paintings exhibited(D)creating a name for a new style of painting47 The word“ affront” in line 22 is closest in meaning to(A)insult(B)encouragement(C)return(D)credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A)The small number of paintings on display(B)Lack of interest in exhibitions by young artists(C)The similarity between all the paintings exhibited(D)Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example ofan artist who(A)became as famous as Monet(B)was consistently praised by art critics(C)described the enthusiasm of the Impressionists for their work(D)was in favor of a traditional style of painting50 The word“ others” in line 27 refers to(A)art critics(B)fellow artists(C)individual differences(D)new styles0308 答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABACACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB。

托福阅读原文【1】A heated debate has enlivened recent studies of evolution. Darwin's original thesis, and the viewpoint supported by evolutionary gradualists, is that species change continuously but slowly and in small increments. Such changes are all but invisible over the short time scale of modern observations, and, it is argued, they are usually obscured by innumerable gaps in the imperfect fossil record. Gradualism, with its stress on the slow pace of change, is a comforting position, repeated over and over again in generations of textbooks. By the early twentieth century, the question about the rate of evolution had been answered in favor of gradualism to most biologists' satisfaction.【2】Sometimes a closed question must be reopened as new evidence or new arguments based on old evidence come to light. In 1972 paleontologist Stephen Jay Gould and Niles Eldredge challenged conventional wisdom with an opposing viewpoint, the punctuated equilibrium hypothesis, which posits that species give rise to new species in relatively sudden bursts, without a lengthy transition period. These episodes of rapid evolution are separated by relatively long static spans during which a species may hardly change at all.【3】The punctuated equilibrium hypothesis attempts to explain a curious feature of the fossil record—one that has been familiar to paleontologist for more than a century but has usuallybeen ignored. Many species appear to remain unchanged in the fossil record for millions of years—a situation that seems to be at odds with Darwin's model of continuous change. Intermediated fossil forms, predicted by gradualism, are typically lacking. In most localities a given species of clam or coral persists essentially unchanged throughout a thick formation of rock, only to be replaced suddenly by a new and different species.【4】The evolution of North American horse, which was once presented as a classic textbook example of gradual evolution, is now providing equally compelling evidence for punctuated equilibrium. A convincing 50-million-year sequence of modern horse ancestors—each slightly larger, with more complex teeth, a longer face, and a more prominent central toe—seemed to provide strong support for Darwin's contention that species evolve gradually. But close examination of those fossil deposits now reveals a somewhat different story. Horses evolved in discrete steps, each of which persisted almost unchanged for millions of years and was eventually replaced by a distinctive newer model. The four-toed Eohippus preceded the three-toed Miohippus, for example, but North American fossil evidence suggests a jerky, uneven transition between the two. If evolution had been a continuous, gradual process, one might expect that almost every fossil specimen would be slightly different from every year.【5】If it seems difficult to conceive how major changes could occur rapidly, consider this: an alteration of a single gene in files is enough to turn a normal fly with a single pair of wings into one that has two pairs of wings.【6】The question about the rate of evolution must now be turned around: does evolution ever proceed gradually, or does italways occur in short bursts? Detailed field studies of thick rock formations containing fossils provide the best potential tests of the competing theories.【7】Occasionally, a sequence of fossil-rich layers of rock permits a comprehensive look at one type of organism over a long period of time. For example, Peter Sheldon's studies of trilobites, a now extinct marine animal with a segmented body, offer a detailed glimpse into three million years of evolution in one marine environment. In that study, each of eight different trilobite species was observed to undergo a gradual change in the number of segments—typically an increase of one or two segments over the whole time interval. No significant discontinuous were observed, leading Sheldon to conclude that environmental conditions were quite stable during the period he examined.【8】Similar exhaustive studies are required for many different kinds of organisms from many different periods. Most researchers expect to find that both modes of transition from one species to another are at work in evolution. Slow, continuous change may be the norm during periods of environmental stability, while rapid evolution of new species occurs during periods of environment stress.

By the mid-nieenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use.This had bee possible because a new household convenience, the icebox, a precursor of the modern refrigerator, hadbeen invented.Making an efficient icebox was not as easy as we might now suppose. In the early nieenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The monsense notion thatthe best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the icethat performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nieenth century did inventors achieve the delicate balance of insulation and circulation needed for anefficient icebox.But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up therapidly melting stuff in the tubs of his petitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.1. What does the passage mainly discuss?(A) The influence of ice on the diet(B) The development of refrigeration(C) The transportation of goods to market(D) Sources of ice in the nieenth century2. Aording to the passage , when did the word "icebox" bee part of the language of the United States?(A) in 1803(B) sometime before 1850(C) during the civil war(D) near the end of the nieenth century3. The phrase "forward-looking" in line 4 is closest in meaning to(A) progressive(B) popular(C) thrifty(D) well-established4. The author mentions fish in line 4 because(A) many fish dealers also sold ice(B) fish was shipped in refrigerated freight cars(C) fish dealers were among the early mercial users of ice(D) fish was not part of the ordinary person's diet before the invention of the icebox5. The word "it" in line 5 refers to(A) fresh meat(B) the Civil War(C) ice(D) a refrigerator6. Aording to the passage , which of the following was an obstacle to the development of the icebox?(A) Competition among the owners of refrigeratedfreight cars(B) The lack of a work for the distribution of ice(C) The use of insufficient insulation(D) Inadequate understanding of physics7. The word "rudimentary" in line 12 is closest in meaning to(A) growing(B) undeveloped(C) necessary(D) uninteresting8. Aording to the information in the second paragraph, an ideal icebox would(A) pletely prevent ice from melting(B) stop air from circulating(C) allow ice to melt slowly(D) use blankets to conserve ice9. The author describes Thomas Moore as having been "on the right track" (lines 18-19) to indicate that(A) the road to the market passed close to Moore's farm(B) Moore was an honest merchant(C) Moore was a prosperous farmer(D) Moore's design was fairly suessful10. Aording to the passage , Moore's icebox allowed him to(A) charge more for his butter(B) travel to market at night(C) manufacture butter more quickly(D) produce ice all year round11.

In the minds of agrarian thinkers and writers ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,which ended in 1865 ,was the age of(5 )the farmer in the United States .Agrarian philosophers ,represented most eloquently by Thomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a good society, their political virtue ,and their Superior morality .And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10) all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15) launched exploring expeditions into prospectivefarmlands in the West .In addition ,government trade policies facilitated the exporting of agricultural products.For their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20) more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops and pure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunning rapidity .But farmers responded (25) less to the expectations of agrarians andgovernment inducements than to growing market opportunities .European demand for food from the United States seemed insatiable .

(c)The growing settlement of the West led to a decrease in agricultural production.(d)Farmers were influenced more by government policies than by market opportunities.Question 21-29The wide variety of climates in North America has helped spawn a complex pattern ofsoil regions. In general, the realm’s soils also reflect the broad environmental partitioninginto “humid America” and “arid America.” Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher inacid content) nor alkaline(higher in salt content).fertilization is necessary to achieve the desired level of neutrality between thetwo. Arid America’s soils are typically alkaline and must be fertilized back towardneutrality by adding acidic compounds. Although many of these dryland soils, particularly in the Great Plains, are quite fertile, European settlers learned over a century ago that(10) water is the main missing ingredient in achieving their agricultural potential. In the1970’s, certain irrigation methods were perfected and finally provided a real opportunity to expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15) and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but the enormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20) the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as one crosses the (25) border into the Northeast United States. As oneproceeds toward the Southeast, broadleafvegetation becomes dominant. Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.21 What aspect of North America does the passage mainly discuss?(A)The wide variety of climates(B)Soil types and vegetation patterns(C)Improved irrigation methods and the expansion of agriculture(D)The change in precipitation patterns22 The word “spawn ” in line 1 is closest in meaning to(A)distinguish(B)eliminate(C)protect(D)create23 The word “partitioning” in line 2 is closest in meaning to(A)division(B)modification(C)opening(D)circulating24 According to the passage, acidic soils tent to be associated with(A)a high salt content(B)an increase in farming(C)large amounts of rain(D)glacial meltwater25 The word “enhanced” in line 13 is closest in meaning to(A)implied(B)increased(C)indicated(D)informed26 How did glacial meltdown affect the soil in North America?(A)It redistributed the soil types(B)It added salt to the soil(C)It made the soil more neutral in content(D)It added minerals to the soil27 The phrase “this regionalization scheme” in line 19 refers to the(A)movements of glacial deposits(B)patterns of natural vegetation(C)human modification of the North American environment(D)distinction between humid America and arid America28 The word “transition” in line 23 is closest inmeaning to(A)elevation(B)change(C)advantage(D)condition29 The passage supports which of the following statements?(A)Arid America is not necessarily characterized by the presence of deserts(B)Most of Canada and the northeastern United States consists of short-grass prairies wherever natural vegetation has not been modified by humans(C)The accumulation of loess is primarily the result of irrigation(D)Glaciation removed the fertile layer of soil from much of the Mississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second), the human eye will not reactin time to see the object. A photographic emulsion---that is, a light-sensitive coating on photographic film, paper, or glass---will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used tocapture high-speed movement on film as well as to correct deficiencies of the normal surrounding lighting. Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When the bag was ignited, the metal burned with an intense flash. A contemporary observer reported (10) that “this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd poses.”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’s. In the earliest type, the metal (15) was separated from the oxygen by a thin glass bulb. The flash was fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignitedspontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygen difluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to awhite-hot emission of visible light. The smoke particles are so small that they cool rapidly; butsince they are white, they contribute to thebrilliance by reflecting the light from their still-glowing neighbors. A slightly bigger formof the metal will burn for a longer time.30 What does the passage mainly discuss?(A)The history of the photoflash(B)Theories about how the eye reacts to light(C)The technology of modern photography(D)The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A)recording of an image on film(B)generation of artificial light(C)creation of a photographic emulsion(D)human eye to react to light32 According to the passage, an advantage of usinga photoflash is that it(A)can produce repeated bursts of light(B)intensities colors in photographs(C)is short enough not to bother human eyes(D)supplements existing lighting33 The word “ignited” in line 9 is closest inmeaning to(A)set on fire(B)cut into(C)opened(D)shaken34 Which of the following phrases is defined in paragraph 1?(A)”appreciable period”(line 1)(B)”photographic emulsion”(line 3)(C)”high-speed movement”(line 5)(D)”odd poses”(line 11)35 The word “evolution” in line 12 is closest in meaning to(A)publicity(B)adoption(C)development(D)manufacture36 The function of the glass in the first flashbulbs was to(A)produce the spark that initiated the flash(B)magnify the light produced by the flash(C)protect the photographer from the heat of the flash(D)keep the metal and oxygen apart before the flash37 The word “it” in line 18 refers to(A)oxygen(B)battery(C)wire(D)current38 The word “momentarily” in line 20 is closest in meaning to(A)effortlessly(B)briefly(C)electronically(D)gradually39 According to the passage, the white color of the smoke particles generated by a flashbulb contributes to(A)rapid cooling(B)bright illumination(C)electrical conductivity(D)intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A)thicker wire(B)more oxygen(C)thinner glass(D)continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’s. The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated onthe play of light over objects, people, and nature, breaking up seemingly solid surfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected light in all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoorsto complete the work form memory.(10) Some of the Impressionists’ painting methods were affected by technologicaladvances. For example, the shift from the studio to the open air was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finish their paintings on the spot.(15) Impressionism acquired its name not fromsupporters but from angry art lovers whofelt threatened by the new painting. The term “Impressionism” was born in 1874,whena group of artists who had been working together organized an exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintings exhibited was one called(20)Impression: Sunrise, by Claude Monet(1840-1926),Viewed through hostile eyes,Monet’s painting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet’s title, art critics extended the term “Impressionism” to the entire exhibit. In response, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25) From then until 1886 Impressionism had all the zeal of a “church”, as the painter Renoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A)The impact of some artists’ resistance to the fast pace of life(B)The differences between two major styles of art(C) A technological advance in the materials used by artists(D) A group of artists with a new technique and approach to art42 The word “depict” in line 2 is closest in meaning to(A)reorganize(B)deform(C)represent(D)justify43 According to the passage, which of the following was one of the distinguishing characteristics of Impressionist painting?(A)The emphasis on people rather than nature scenes(B)The way the subjects were presented from multiple angles(C)The focus on small solid objects(D)The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A)They began by making sketches of their subjects(B)They painted their subjects out-of-doors(C)They preferred to paint from memory(D)They used subjects drawn from modern life45 The word “advent” in line 12 is closest in meaning to(A)achievement(B)acceptance(C)arrival(D)advantage46 The exhibition of paintings organized in 1874 resulted in all of the following EXCEPT(A)attracting attention from the public(B) a negative reaction from the press(C)an immediate demand for the paintings exhibited(D)creating a name for a new style of painting47 The word “affront” in line 22 is closest in meaning to(A)insult(B)encouragement(C)return(D)credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A)The small number of paintings on display(B)Lack of interest in exhibitions by young artists(C)The similarity between all the paintingsexhibited(D)Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example of an artist who(A)became as famous as Monet(B)was consistently praised by art critics(C)described the enthusiasm of the Impressionists for their work(D)was in favor of a traditional style of painting50 The word “others” in line 27 refers to(A)art critics(B)fellow artists(C)individual differences(D)new styles0308答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABACACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB。

Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 )generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structurespresent in air closely resemble the microorganisms seen in putrefying materials .He did(10)this by passing air through guncotton filters, the fibers of which stop solid particles. Afterthe guncotton was dissolved in a mixture of alcohol and ether, the particles that it hadtrapped fell to the bottom of the liquid and were examined on a microscope slide .Pasteurfound that in ordinary air these exists a variety of solid structures ranging in size from0.01 mm to more than 1.0 mm .Many of these bodies resembled the reproductive (15)structures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedfrom the organized bodies present in the air .He postulated that these bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary for spontaneous generation and that the air inside the sealed flask was affected in some way(25)by heating so that it would no longer support spontaneous generation. Pasteurconstructed a swan-necked flask in which putrefying materials could he heated to boiling, but aircould reenter. The bends in the neck prevented microorganisms from getting in the flask.. Material sterilized in such a flask did not putrefy.1,What does the passage mainly discuss?(a)Pasteur’s influence on the development of the microscope.(b)The origin of the theory of spontaneous generation .(c)The effects of pasteurization on food.(d)Pasteur’s argument against the theory of spontaneous generation .2,The phrase “teeming with ”in line 2 is closest in meaning to(a)full of(b)developing into(c)resistant to(d)hurt by3,Which of the following questions did the theory of spontaneous generation attempt to answer?(a)What is the origin of the living organisms are seen on some food?(b)How many types of organisms can be found on food?(c)What is the most effective way to prepare living organisms for microscopic examination?(d)How long can food stand before it putrefies?4,The word “resemble” in line 9 is closest in meaning to(a)benefit from(b)appear similar to(c)join together with(d)grow from5,The purpose of the “guncotton” mentioned in paragraph 2 was to(a)trap particles for analysis(b)slow the process of putrefaction(c)increase the airflow to the microscopic slide(d)aid the mixing of alcohol and ether6,The author mention “1.0mm”in line 14 in describing the(a)thickness of a layer of organisms that was deposited on an object(b)diameter of the fibers that were in the guncotton filters(c)thickness of the microscope slides that were used(d)size of the particles that that were collected7.The word “postulated”in line 19 is closest in meaning to(a)analyzed(b)doubted(c)persuaded(d)suggested8.The objects that Pasteut removed from the air in his experiment were remarkable because they were(a)primarily single-celled organisms(b)no different from objects found in putrefying materials(c)fairly rare(d)able to live in a mixture of alcohol and ether9.The word “it” in line 22 refers to(a)a nutrient solution(b)a glass flask(c)boiling(d)spontaneous generation10.According to paragraph 3,proponents of spontaneous generation believed thatwhich of the following was important for the process to succeed ?(a)A sealed container(b)Fresh air(c)Heat(d)The presence of nutrients11.It can be inferred from paragraph 3 that Pasteur employed a swam-necked flask to(a)store sterilized liquids for use in future experiments(b)prevent heat from building up in a solution(c)disprove a criticism of his conclusions(d)estimate the number of organisms in a liter of airQuestions 12-20In the early decades of the United States ,the agrarian movement promoted the farmeras society’s hero. In the minds of agrarian thinkers and writers ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,which ended in 1865 ,was the age of(5 )the farmer in the United States .Agrarian philosophers ,represented most eloquently byThomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a goodsociety, their political virtue ,and their Superior morality .And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10)all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15) launched exploring expeditions into prospective farmlands in the West .In addition ,government trade policies facilitated the exporting of agricultural products.For their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20)more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops andpure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunning rapidity .But farmers responded(25)less to the expectations of agrarians and government inducements than togrowing market opportunities .European demand for food from the United States seemed insatiable . War, industrialization , and urbanization all kept demand high in Europe . United States citiesand industries grew as well; even industries not directly related to farming thrived becauseof the market, money ,and labor that agriculture provided .12.What does the passage mainly discuss?(a)The agrarian philosophy of Thomas Jefferson(b)The role of the national government in the development of agriculture(c)Improvements in farming techniques(d)The impact of the increased importance of the farmer13.The word “depended” in line 3 is closest in meaning to(a)improved(b)relied(c)demanded(d)explained14.The author mentions Thomas Jefferson in paragraph 1 as an example of(a)a leader during the Revolution(b)an inventor of new farming techniques(c)a philosopher who believed farmers were essential to the creation of a good society(d)a farmer who guided the agrarian movement toward an emphasis on economic development15.The phrase “subscribed to” in line 8 is closest in meaning to(a)contributed to(b)agreed with(c)thought about(d)expanded on16.Which of the following statements is supported by the information in paragraph 1?(a)All government policy makers accepted Jefferson’s views of agriculture and farmers.(b)Agricultural production declined between 1783 and 1861.(c)The majority of farmers worked for the government.(d)Agriculture was a vital part of the nation’s economy.17.According to the passage , the national and state governments did all of the following EXCEPT(a)build roads(b)import new plant varieties(c)give farmers money for their crops(d)develop policies that helped farmers export their products18.All of the following are mentioned as examples of farmers’ meeting the expectations of agrarian philosophers EXCEPT(a)obtaining information from farm newspapers(b)accumulating personal wealth(c)planting new crops(d)becoming more scientific19.The word “stunning” in line 24 is closest in meaning to(a)predictable(b)impressive(c)famous(d)gradual20.Which of the following statements is best supported by paragraph 4?(a)Agricultural development contributed to development in other parts of the economy.(b)European agricultural products were of a higher quality than those produced in the United States.(c)The growing settlement of the West led to a decrease in agricultural production.(d)Farmers were influenced more by government policies than by market opportunities.Question 21-29The wide variety of climates in North America has helped spawn a complex pattern ofsoil regions. In general, the realm’s soils also reflect the broad environmental partitioninginto “humid America” and “arid America.” Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher in acid content) nor alkaline(higher insalt content).fertilization is necessary to achieve the desired level of neutrality between thetwo. Arid America’s soils are typically alkaline and must be fertilized back toward neutrality by adding acidic compounds. Although many of these dryland soils, particularlyin the Great Plains, are quite fertile, European settlers learned over a century ago that(10) water is the main missing ingredient in achieving their agricultural potential. In the1970’s, certain irrigation methods were perfected and finally provided a real opportunityto expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15)and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but theenormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20)the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as onecrosses the(25) border into the Northeast United States. As one proceeds toward the Southeast,broadleaf vegetation becomes dominant. Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.21 What aspect of North America does the passage mainly discuss?(A) The wide variety of climates(B) Soil types and vegetation patterns(C) Improved irrigation methods and the expansion of agriculture(D) The change in precipitation patterns22 The word “spawn ” in line 1 is closest in meaning to(A) distinguish(B) eliminate(C) protect(D) create23 The word “partitioning” in line 2 is closest in meaning to(A) division(B) modification(C) opening(D) circulating24 According to the passage, acidic soils tent to be associated with(A) a high salt content(B) an increase in farming(C) large amounts of rain(D) glacial meltwater25 The word “enhanced” in line 13 is closest in meaning to(A) implied(B) increased(C) indicated(D) informed26 How did glacial meltdown affect the soil in North America?(A) It redistributed the soil types(B) It added salt to the soil(C) It made the soil more neutral in content(D) It added minerals to the soil27 The phrase “this regionalization scheme” in line 19 refers to the(A) movements of glacial deposits(B) patterns of natural vegetation(C) human modification of the North American environment(D) distinction between humid America and arid America28 Th e word “transition” in line 23 is closest in meaning to(A) elevation(B) change(C) advantage(D) condition29 The passage supports which of the following statements?(A) Arid America is not necessarily characterized by the presence of deserts(B) Most of Canada and the northeastern United States consists of short-grassprairies wherever natural vegetation has not been modified by humans(C) The accumulation of loess is primarily the result of irrigation(D) Glaciation removed the fertile layer of soil from much of the Mississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second), the human eye will not reactin time to see the object. A photographic emulsion---that is, a light-sensitive coating on photographic film, paper, or glass---will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used to capture high-speed movement on film as wellas to correct deficiencies of the normal surrounding lighting. Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When thebag was ignited, the metal burned with an intense flash. A contemporary observer reported(10) that “this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd poses.”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’s. In the earliest type, the metal(15) was separated from the oxygen by a thin glass bulb. The flash was fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignited spontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygendifluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to a white-hot emission of visible light. Thesmoke particles are so small that they cool rapidly; but since they are white, they contribute to the brilliance by reflecting the light from their still-glowing neighbors. A slightly bigger formof the metal will burn for a longer time.30 What does the passage mainly discuss?(A) The history of the photoflash(B) Theories about how the eye reacts to light(C) The technology of modern photography(D) The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A) recording of an image on film(B) generation of artificial light(C) creation of a photographic emulsion(D) human eye to react to light32 According to the passage, an advantage of using a photoflash is that it(A) can produce repeated bursts of light(B) intensities colors in photographs(C) is short enough not to bother human eyes(D) supplements existing lighting33 The word “ignited” in line 9 is closest in meaning to(A) set on fire(B) cut into(C) opened(D) shaken34 Which of the following phrases is defined in paragraph 1?(A)”appreciable period”(line 1)(B)”photographic emulsion”(line 3)(C)”high-speed movement”(line 5)(D)”odd poses”(line 11)35 The word “evolution” in line 12 is closest in meaning to(A) publicity(B) adoption(C) development(D) manufacture36 The function of the glass in the first flashbulbs was to(A) produce the spark that initiated the flash(B) magnify the light produced by the flash(C) protect the photographer from the heat of the flash(D) keep the metal and oxygen apart before the flash37 The word “it” in line 18 refers to(A) oxygen(B) battery(C) wire(D) current38 The word “momentarily” in line 20 is closest in meaning to(A) effortlessly(B) briefly(C) electronically(D) gradually39 According to the passage, the white color of the smoke particles generated by a flashbulb contributes to(A) rapid cooling(B) bright illumination(C) electrical conductivity(D) intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A) thicker wire(B) more oxygen(C) thinner glass(D) continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’s.The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated onthe play of light over objects, people, and nature, breaking up seemingly solidsurfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected lightin all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoorsto complete the work form memory.(10) Some of the Impressionists’ painting methods were affected by technologicaladvances. For example, the shift from the studio to the open air was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finish their paintings on the spot.(15)Impressionism acquired its name not from supporters but from angry art lovers whofelt threatened by the new painting. The term “Impressionism” was born in 1874,whena group of artists who had been working together organized an exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintings exhibited was one called(20)Impression: Sunrise, by Claude Monet(1840-1926),Viewed through hostile eyes,Monet’s painting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet’s title, art critics extended the term “Impressionism” to the entire exhibit. In response, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25)From then until 1886 Impressionism had all the zeal of a “church”, as the painter Renoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A) The impact of some artists’ resistance to the fast pace of life(B) The differences between two major styles of art(C) A technological advance in the materials used by artists(D) A group of artists with a new technique and approach to art42 The word “depict” in line 2 is closest in meaning to(A) reorganize(B) deform(C) represent(D) justify43 According to the passage, which of the following was one of the distinguishing characteristics of Impressionist painting?(A) The emphasis on people rather than nature scenes(B) The way the subjects were presented from multiple angles(C) The focus on small solid objects(D) The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A) They began by making sketches of their subjects(B) They painted their subjects out-of-doors(C) They preferred to paint from memory(D) They used subjects drawn from modern life45 The word “advent” in line 12 is closest in meaning to(A) achievement(B) acceptance(C) arrival(D) advantage46 The exhibition of paintings organized in 1874 resulted in all of the following EXCEPT(A) attracting attention from the public(B) a negative reaction from the press(C) an immediate demand for the paintings exhibited(D) creating a name for a new style of painting47 The word “affront” in line 22 is closest in meaning to(A) insult(B) encouragement(C) return(D) credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A) The small number of paintings on display(B) Lack of interest in exhibitions by young artists(C) The similarity between all the paintings exhibited(D) Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example of an artist who(A) became as famous as Monet(B) was consistently praised by art critics(C) described the enthusiasm of the Impressionists for their work(D) was in favor of a traditional style of painting50 The word “others” in line 27 refers to(A) art critics(B) fellow artists(C) individual differences(D) new styles0308答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABA CACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB。

Crown of Thorns Starfish and Coral Reefs冠状棘海星，话题重复2011.01.08珊瑚的消失和一种海星的数量猛增有关系，主要说的是导致猛增的原因(环境+人)词汇题补充：outbreak = sudden increaseaccompany = occur along withconverge = come togetherseverity = seriousness原题重现：The crown of thorns starfish, Acanthaster Tlanci, is large, twenty-five to thirty-five centimeters in diameter, and has seven to twenty-one arms that are covered in spines. It feeds primarily on coral and is found from the Indian Ocean to the west coast of Central America, usually at quite low population densities. Sincethe mid-1950s, population outbreaks at densities four to six times greater than normal have occurred at the same time in places such as Hawaii, Tahiti, Panama, and the Great Barrier Reef. The result has often been the loss of a fifty percent to nearly one hundred percent of the coral cover over large areas.A single Acanthaster can consume five to six square meters of coral polyps per year, and dense populations can destroy up to six square kilometers per year and move on rapidly. Acanthasters show a preference for branching corals, especially Acroporids. After an outbreak in a particular area, it is common to find that Acroporids have been selectively removed, leaving a mosaic of living and dead corals. In places where Acroporids previously dominated the community devastation can be almost complete, and local areas of reefs have collapsed.Areas of dead coral are usually colonized rapidly by algae and often are later colonized by sponges and soft corals. Increases in abundance of plant-eating fish and decreases in abundance of coral-feeding fish accompany these changes. Coral larvae settle among the algae and eventually establish flourishing coral colonies. In ten to fifteen years the reefs often return to about the same percentage of coral cover as before. Development of a four-species diversity takes about twenty years.Two schools of thought exist concerning the cause of these outbreaks. One group holds that they are natural phenomena that have occurred many times in the past, citing old men's recollections of earlier outbreaks and evidence from traditional cultures. The other group maintains that recent human activities ranging from physical coral destruction through pollution to predator removal have triggered these events.One theory, the adult aggregation hypothesis, maintains thatmost species is more abundant than we realize when a storm destroys coral and causes a food shortage. The adult Acanthasters converge on remaining portions of healthy coral and feed hungrily. Certainly there have been outbreaks of Acanthaster following large storms, but there is little evidence that the storms have caused the enough reef damage to create a food shortage for these starfish.Two other hypotheses attempt to explain the increased abundance of Acanthaster after episodes of high terrestrial runoff following storms. The first hypothesis is that low salinity and high temperatures favor the survival of the starfish larvae. The second hypothesis emphasizes the food web aspect, suggesting that strong fresh water runoff brings additional nutrients to the coastal waters, stimulating phytoplankton production and promoting more rapid development and better survival of the starfish larvae.Those favoring anthropogenic (human influenced) causes have pointed to the large proportion of outbreaks that have been near centers of human populations. It has been suggested that coral polyps are the main predators of the starfish larvae. Destruction of coral by blasting and other bad land use practices would reduce predation on the starfish larvae and cause a feedback in which increases in Acanthaster populations cause still further coral destruction. Unfortunately, there are too few documented instances of physical destruction of coral being followed by outbreaks of Acanthaster for these hypotheses to be fully supported.Another group of hypothesis focuses on removal of Acanthaster's predators. Some have suggested that the predators might have been killed off by pollution whereas othershave suggested that the harvesting of vertebrate and invertebrate predators of Acanthaster could have reduced mortality and caused increased abundance of adults. The problem with this group of hypothesis is that it is difficult to understand how reduced predation would lead to sudden increases in Acanthaster numbers in several places at the same time in specific years. It seems probable that there is no single explanation but that there are elements of the truth in several of the hypotheses. That is there are natural processes that have led to outbreaks in the past, but human impact has increased the frequency and severity of the outbreaks.3.Dorset Culture格林兰岛Dorset Culture的起源，首先是由于气候变冷，一部分人迁走了，另一部分留下来的人创立了文明。

11月15日托福阅读真题(新东方版)
11月15日托福阅读真题（新东方版）第一篇考生回忆：本文属讲的是热带雨林树木的种类。
先讲了在温带地区树的种类非常好区分，但是在热带去不是这个样子。
接下来说开花的情况不一样。
在干湿分明的雨林中，花是随着雨季开放的。
在很多雨林一直都有雨，那么它们如何授粉?应该是一起同时开花。
接下来说叶子难以区分，大部分叶子要进化成很厚的样子，而且叶尖会滴水。
所以都长得很像。
另外一种辨别的方法是看树干。
虽然树干也很像。
接下来说在温带地区，树种没有那么难以辨别。
数量不会超过半打，但是热带的确是难以辨别。
第二篇考生回忆：主要讨论的是地球与宇宙年份的测定。
先说地球年份的测算。
一开始说可以通过陨石的年份来推测。
但是因为地球上面有水、火山和地壳运动，所以岩石的成分无法分析。
进一步的分析方法是岩石的辐射衰变。
得出来的结论是46亿年，这个测算的结果和月球上测算的结果是一样的。
因为月球上没有地球上的这些侵蚀，所以月球的测算数据相对准确。
接下来是宇宙年份的测算。
宇宙的年份重要是通过红移(red shift)来测量。
测算的结果发现宇宙一直在不断地膨胀。
第三篇考生回忆：讨论恐龙灭绝的原因。
首先说尝试解释恐龙灭绝的假说是在太多。
分析了6亿5千万年之前的底层，发现很好含钙的化石，其中就有恐龙的。
超过这个时间之后恐龙化石就再也找不到了，也就是认为恐龙灭绝了。
接下来提出一个假说，认为是辐射所导致恐龙基因变异导致恐龙灭绝。
恰好是每隔几百万年地球的南北磁极就会发生倒置，地磁场太弱，所以恐龙灭绝了。
后来又认为是陨石撞击地球，但是恐龙并没有立马就全部死绝，而是通过破坏全球的气候，通过影响底层生物链的生物最终使得恐龙饿死。
这个理论认为这些间接因素也很关键。
最后说火山运动也可能导致恐龙灭绝。
举了印度的例子，长时间的火山爆发导致了大片新火山岩的形成。
火山爆发喷出的灰烬遮盖了太阳，使得全球温带骤降。
但也有温室气体的排放会导致温度提高。
后来说这样的结果导致了新物种的大爆发。

20XX年11月份托福阅读真题及答案Questions 1-10As Philadelphia grew from a small town into a city in the first half of the eighteenthcentury, it became an increasingly important marketing center for a vast and growing agricultural hinterland. Market days saw the crowded city even more crowded, as line fanners from within a radius of 24 or more kilometers brought their sheep, cows,pigs, vegetables, cider, and other products for direct sale to the townspeople. The High Street Market was continuously enlarged throughout the period until 1736, when it reached from Front Street to Third. By 1745 New Market was opened on Second Street between Pine and Cedar. The next year the Callowhill Market began operation.Along with market days, the institution of twice-yearly fairs persisted in Philadelphia even after similar trading days had been discontinued in other colonial cities. The fairs provided a means of bringing handmade goods from outlying places towould-be buyers in the city. Linens and stockings from Germantown, for example,were popular items.Auctions were another popular form of occasional trade. Because of the petition, retail merchants opposed these as well as the fairs. Althoughgovernmental attempts to eradicate fairs and auctions were less than successful, the ordinary course of economic development was on the merchants' side, as increasing business specialization became the order of the day. Export merchants became differentiated from their importing counterparts, and specialty shops began to appear in addition to general stores selling a variety of goods. One of the reasons Philadelphia's merchants generally prospered was because thesurrounding area was undergoing tremendous economic and demographic growth.They did their business, after all, in the capital city of the province. Not only did theycater to the governor and his circle, but citizens from all over the colony came to the capital for legislative sessions of the assembly and council and the meetings of thecourts of justice.1. What does the passage mainly discuss?(A) Philadelphia's agriculture importance(B) Philadelphia's development as a marketing center(C) The sale of imported goods in Philadelphia(D) The administration of the city of Philadelphia2. It can be inferred from the passage that new markets opened in Philadelphia because(A) they provided more modem facilities than older markets(B) the High Street Market was forced to close(C) existing markets were unable to serve the growing population(D) farmers wanted markets that were closer to the farms.3. The word "hinterland " in line 3 is closest in meaning to(A) tradition(B) association(C) produce(D) region4.

According to the passage, fairs in Philadelphia were held(A) on the same day as market says(B) as often as possible(C) a couple of times a year(D) whenever the government allowed it7. It can be inferred that the author mentions "Linens and stockings" in line 12 to show that they were items that(A) retail merchants were not willing to sell(B) were not available in the stores in Philadelphia(C) were more popular in Germantown man in Philadelphia(D) could easily be transported8. The word "eradicate" in line 16 is closest in meaning to(A) eliminate(B) exploit(C) organize(D) operate9.

They continueto look for better ways to increase egg production and to improve chick survival rates.line When parrots incubate their eggs in the wild, the temperature and humidity of the(5) nest are controlled naturally. Heat is transferred from the bird's skin to the top portionof the eggshell, leaving the sides and bottom of the egg at a cooler temperature. Thistemperature gradient may be vital to successful hatching. Nest construction cancontribute to this temperature gradient Nests of loosely arranged sticks, rocks, or dirtare cooler in temperature at the bottom where the egg contacts the nesting material.(10) Such nests also act as humidity regulators by allowing rain to drain into the bottomsections of the nest so that the eggs are not in direct contact with the water. As thewater that collects in the bottom of the nest evaporates, the watervapor rises and isheated by the incubating bird, which adds significant humidity to the incubationenvironment(15) In artificial incubation programs, aviculturists remove eggs from the nests of parrotsand incubate them under laboratory conditions. Most mercial incubators heat theeggs fairly evenly from top to bottom, thus ignoring the bird's method of naturalincubation, and perhaps reducing the viability and survivability of the hatching chicks.When incubators are not used, aviculturists sometimes suspend wooden boxes outdoors(20) to use as nests in which to place eggs. In areas where weather can bee cold aftereggs are laid, it is very important to maintain a deep foundation of nesting material toact as insulator against the cold bottom of the box. If eggs rest against the woodenbottom in extremely cold weather conditions, they can bee chilled to a point wherethe embryo can no longer survive. Similarly, these boxes should be protected from(25) direct sunlight to avoid high temperatures that are also fatal to the growing embryo.Nesting material should be added in sufficient amounts to avoid both extremetemperature situations mentioned above and assure that the eggs have a soft, secureplace to rest.11. What is the main idea of the passage?(A) Nesting material varies according to theparrots' environment.(B) Humidity is an important factor inincubating parrots' eggs.(C) Aviculturists have constructed the idealnest box for parrots.(D) Wild parrots' nests provide informationuseful for artificial incubation.12. The word "They" in line 2 refers to(A) aviculturists(B)birds(C)eggs(D) rates13. According to paragraph 2, when thetemperature of the sides and bottom of the eggare cooler than the top, then(A) there may be a good chance forsuccessful incubation(B) the embryo will not develop normally(C) the incubating parent moves the egg toa new position.(D) the incubation process is slowed down14. According to paragraph 2, sticks, rocks, or dirt are used to(A) soften the bottom of the nest for the newlyhatched chick(B) hold the nest together(C) help lower the temperature at the bottom ofthe nest(D) make the nest bigger15. According to paragraph 2, the construction of the nest allows water to(A) provide a beneficial source of humidityin the nest(B) loosen the materials at the bottom of thenest(C) keep the nest in a clean condition(D) touch the bottom of the eggs16. All of the following are part of a parrot'sincubation method EXCEPT(A) heating the water vapor as it rises from thebottom of the nest(B) arranging nesting material at the bottom ofthe nest(C) transferring heat from the parent to the topof the eggshell(D) maintaining a constant temperature on theeggshell17. The word "suspend" in line 19 is closest inmeaning to(A) build(B) paint(C)hang(D) move18. The word "fatal" in line 25 is closest inmeaning to(A) close(B) deadly(C) natural(D) hot19. The word "secure" in line 27 is closest inmeaning to(A) fiesh(B)diy(C)safe(D)warm20. According to paragraph 3, a deep foundation of nesting material provides(A) a constant source of humidity(B) a strong nest box(C) more room for newly hatched chicks(D) protection against cold weather21. Which of the following is a problem withmercial incubators?(A) They lack the natural temperature changesof the outdoors.(B) They are unable to heat the eggs evenly(C) They do not transfer heat to the egg in thesame way the parent bird does.(D) They are expensive to operate.22. Which of the following terms is defined in thepassage?(A) Aviculturists (line I)(B) Gradient (line 8)(C) Incubation (line 15)(D) Embryo (line 24)Questions 23-33The mineral particles found in soil range in size from microscopic clay particlesto large boulders. The most abundant particles—sand, silt, and clay—are the focusof examination in studies of soil texture. Texture is the term used to describe theline posite sizes of particles in a soil sample, typically several representative handfuls.(5) To measure soil texture, the sand, silt, and clay particles are sorted out by size andweight. The weights of each size are then expressed as a percentage of the sampleweight.In the field, soil texture can be estimated by extracting a handful of sod andsqueezing the damp soil into three basic shapes; (1) cast, a lump formed by squeezing(10) a sample in a clenched fist; (2) thread, a pencil shape formed by rolling soil betweenthe palms; and (3) ribbon, a flatfish shape formed by squeezing a small sample betweenthe thumb and index finger. The behavioral characteristics of the soil when molded intoeach of these shapes, if they can be formed at all, provides the basis for a generaltextural classification. The behavior of the soil in the hand test is determined by the(15) amount of clay in the sample. Clay particles are highly cohesive, and when dampened,behave as a plastic. Therefore the higher the clay content in a sample, the more refinedand durable the shapes into which it can be molded.Another method of determining soil texture involves the use of devices calledsediment sieves, screens built with a specified mesh size. When the soil is filtered(20) through a group of sieves, each with a different mesh size, the particles beegrouped in corresponding size categories. Each category can be weighed to make atextural determination. Although sieves work well for silt, sand, and larger particles,they are not appropriate for clay particles. Clay is far too small to sieve accurately;therefore, in soils with a high proportion of clay, the fine particles are measured on the(25) basis of their settling velocity when suspended inwater .Since clays settle so slowly,they are easily segregated from sand and silt. The water can be drawn off andevaporated, leaving a residue of clay, which can be weighed.23. What does the passage mainly discuss?(A) Characteristics of high quality soil(B) Particles typically found in most soils(C) How a high clay content affects thetexture of soil(D) Ways to determine the texture of soil24. The author mentions "several representativehandrals" in line 4 in order to show(A) the range of soil samples(B) the process by which soil is weighed(C) the requirements for an adequate soilsample(D) how small soil particles are25. The phrase "sorted out" in line 5 is closest inmeaning to(A) mixed(B) replaced(C) carried(D) separated26. It can be inferred mat the names of the threebasic shapes mentioned in paragraph 2 reflect(A) the way the soil is extracted(B) the results of squeezing the soil(C) the need to check more than onehandful(D) the difficulty of forming differentshapes27. The word "dampened" in line 15 is closest in meaning to(A) damaged(B) stretched(C) moistened(D) examined28. Which of the following can be inferred from the passage about a soil sample with little or no clay in it?(A) It is not very heavy.(B) It may not hold its shape when molded.(C) Its shape is durable(D) Its texture cannot be classified29. The word "they" in line 23 refers to(A) categories(B) sieves(C) larger particles(D) clay particles30. It can be inferred from the passage that the sediment sieve has an advantage over the hand test in determining soil texture because(A) using the sieve takes less time(B) the sieve can measure clay(C) less training is required to use the sieve(D) the sieve allows for a more exactmeasure31. During the procedure described in paragraph 3, when clay particles are placed into water they(A) stick to the sides of the water container(B) take some time to sink to the bottom(C) separate into different sizes(D) dissolve quickly32. The word "fine" in line 24 is closest inmeaning to(A) tiny(B) many(C) excellent(D) various33. All of the following words are defined in thepassage EXCEPT(A) texture (line 3)(B) ribbon (line 11)(C) sediment sieves (line 19)(D) evaporated (line 27)Questions 34-43A number of factors related to the voice reveal the personality of the speaker.The first is the broad area of munication, which includes imparting informationby use of language, municating with a group or an individual, and specializedline munication through performance. A person conveys thoughts and ideas through(5) choice of words, by a tone of voice that is pleasant or unpleasant, gentle or harsh, bythe rhythm that is inherent within the language itself, and by speech rhythms that areflowing and regular or uneven and hesitant, and finally, by the pitch and melody of theutterance. When speaking before a group, a person's tone may indicate unsureness orfright, confidence or calm. At interpersonal levels, the tone may reflect ideas and(10) feelings over and above the words chosen, or may belie them. Here the conversant'stone can consciously or unconsciously reflect intuitive sympathy or antipathy, lack ofconcern or interest, fatigue, anxiety, enthusiasm or excitement, all of which are .usuallydiscernible by the acute listener. Public performance is a manner of municationthat is highly specialized with its own techniques for obtaining effects by voice and /or(15) gesture. The motivation derived from the text, and in the case of singing, the music, inbination with the performer's skills, personality, and ability to create empathy willdetermine the success of artistic, political, or pedagogic munication.Second, the voice gives psychological clues to a person'sself-image, perception ofothers, and emotional health. Self-image can be indicated by a tone of voice that is(20) confident, pretentious, shy, aggressive, outgoing, or exuberant, to name only a fewpersonality traits. Also the sound may give a clue to the facade or mask of that person,for example, a shy person hiding behind an overconfident front. How a speakerperceives the listener's receptiveness, interest, or sympathy in any given conversationcan drastically alter the tone of presentation, by encouraging or discouraging the(25) speaker. Emotional health is evidenced in the voice by free and melodic sounds of thehappy, by constricted and harsh sound of the angry, and by dull and lethargic qualitiesof the depressed34. What does the passage mainly discuss?(A) The function of the voice in performance(B) The connection between voice andpersonality(C) munication styles(D) The production of speech35. What does the author mean by staring that, "At interpersonal levels, tone may reflect ideas and feelings over and above the words chosen"(lines 9-10)?(A) Feelings are expressed with different wordsthan ideas are.(B) The tone of voice can cany informationbeyond the meaning of words.(C) A high tone of voice reflects an emotionalmunication.(D) Feelings are more difficult to express thanideas.36. The word "Here" in line 10 refers to(A) interpersonal interactions(B) the tone(C) ideas and feelings(D) words chosen37. The word "derived" in line 15 is closest inmeaning to(A) discussed(B) prepared(C) registered(D) obtained38. Why does the author mention "artistic,political, or pedagogic munication" in line17?(A) As examples of public performance(B) As examples of basic styles ofmunication(C) To contrast them to singing(D) To introduce the idea of self-image39. According to the passage, an exuberant tone of voice, may be an indication of a person's(A) general physical health(B) personality(C) ability to municate(D) vocal quality40. According to the passage, an overconfidentfront may hide(A) hostility(B) shyness(C) friendliness(D) strength41. The word "drastically" in line 24 is closest inmeaning to(A) frequently(B) exactly(C) severely(D) easily42. The word "evidenced" in line 25 is closest inmeaning to(A) questioned(B) repeated(C) indicated(D) exaggerated43. According to the passage, what does aconstricted and harsh voice indicate?(A) Lethargy(B) Depression(C) Boredom(D) AngerQuestions 44-50As the twentieth century began, the importance of formal education in the UnitedStates increased The frontier had mostly disappeared and by 1910 most Americanslived in towns and cities. Industrialization and the bureaucratization of economicline life bined with a new emphasis upon credentials and expertise to make schooling(5) increasingly important for economic and social mobility. Increasingly, too, schoolswere viewed as the most important means of integrating immigrants into Americansociety.The arrival of a great wave of southern and eastern European immigrants at the turnof the century coincided with and contributed to an enormous expansion of formal(10) schooling. By 1920 schooling to age fourteen or beyond waspulsory in moststates, and the school year was greatly lengthened. Kindergartens, vacation schools,extracurricular activities, and vocational education and counseling extended theinfluence of public schools over the lives of students, many of whom in the largerindustrial cities were the children of immigrants. Classes for adult immigrants were(15) sponsored by public schools, corporations, unions, churches, settlement houses, andother agencies.Reformers early in the twentieth century suggested that education programs shouldsuit the needs of specific populations. Immigrant women were one such population.Schools tried to educate young women so they could occupy productive places in the(20) urban industrial economy, and one place many educators considered appropriate forwomen was the home.Although looking after the house and family was familiar to immigrant women,American education gave homemaking a new definition. In preindustrial economies,homemaking had meant the production as well as the consumption of goods, and it(25) monly included ine-producing activities both inside and outside the home,in the highly industrialized early-twentieth-century United States, however,overproduction rather than scarcity was being a problem. Thus, the ideal Americanhomemaker was viewed as a consumer rather than a producer. Schools trained womento be consumer homemakers cooking, shopping, decorating, and caring for children(30) "efficiently" in their own homes, or if economic necessity demanded, as employeesin the homes of others. Subsequent reforms have made these notions seem quiteout-of-date.44. It can be inferred from paragraph 1 that one important factor in the increasing importanceof education in the United States was(A) the growing number of schools in frontier munities(B) an increase in the number of trainedteachers(C) the expanding economic problems ofschools(D) the increased urbanization of the entire country45. The word "means" in line 6 is closest in meaning to(A) advantages(B) probability(C) method(D) qualifications46. The phrase "coincided with" in line 9 is closest in meaning to(A) was influenced by(B) happened at the same time as(C) began to grow rapidly(D) ensured the success of47. According to the passage, one importantchange in United States education by the1920's was that(A) most places required children to attendschool(B) the amount of time spent on formaleducation was limited(C) new regulations were imposed onnontraditional education(D) adults and children studied in the sameclasses48. Vacation schools and extracurricular activities are mentioned in lines 11-12 to illustrate(A) alternatives to formal educationprovided by public schools(B) the importance of educational changes(C) activities that peted to attract newimmigrants to their programs.(D) the increased impact of public schools onstudents.49.

If eggs rest against the woodenbottom in extremely cold weather conditions, they can become chilled to a point wherethe embryo can no longer survive. Similarly, these boxes should be protected from(25) direct sunlight to avoid high temperatures that are also fatal to the growing embryo.Nesting material should be added in sufficient amounts to avoid both extremetemperature situations mentioned above and assure that the eggs have a soft, secureplace to rest.11.

Which of the following terms is defined in thepassage?(A) Aviculturists (line I)(B) Gradient (line 8)(C) Incubation (line 15)(D) Embryo (line 24)Questions 23-33The mineral particles found in soil range in size from microscopic clay particlesto large boulders. The most abundant particles—sand, silt, and clay—are the focusof examination in studies of soil texture. Texture is the term used to describe theline composite sizes of particles in a soil sample, typically several representative handfuls.(5) To measure soil texture, the sand, silt, and clay particles are sorted out by size andweight. The weights of each size are then expressed as a percentage of the sampleweight.In the field, soil texture can be estimated by extracting a handful of sod andsqueezing the damp soil into three basic shapes; (1) cast, a lump formed by squeezing(10) a sample in a clenched fist; (2) thread, a pencil shape formed by rolling soil betweenthe palms; and (3) ribbon, a flatfish shape formed by squeezing a small sample betweenthe thumb and index finger. The behavioral characteristics of the soil when molded intoeach of these shapes, if they can be formed at all, provides the basis for a generaltextural classification. The behavior of the soil in the hand test is determined by the(15) amount of clay in the sample. Clay particles are highly cohesive, and when dampened,behave as a plastic. Therefore the higher the clay content in a sample, the more refinedand durable the shapes into which it can be molded.Another method of determining soil texture involves the use of devices calledsediment sieves, screens built with a specified mesh size. When the soil is filtered(20) through a group of sieves, each with a different mesh size, the particles becomegrouped in corresponding size categories. Each category can beweighed to make atextural determination. Although sieves work well for silt, sand, and larger particles,they are not appropriate for clay particles. Clay is far too small to sieve accurately;therefore, in soils with a high proportion of clay, the fine particles are measured on the(25) basis of their settling velocity when suspended inwater .Since clays settle so slowly,they are easily segregated from sand and silt. The water can be drawn off andevaporated, leaving a residue of clay, which can be weighed.23. What does the passage mainly discuss?(A) Characteristics of high quality soil(B) Particles typically found in most soils(C) How a high clay content affects thetexture of soil(D) Ways to determine the texture of soil24.

A person conveys thoughts and ideas through(5) choice of words, by a tone of voice that is pleasant or unpleasant, gentle or harsh, bythe rhythm that is inherent within the language itself, and by speech rhythms that areflowing and regular or uneven and hesitant, and finally, by the pitch and melody of theutterance. When speaking before a group, a person's tone may indicate unsureness orfright, confidence or calm. At interpersonal levels, the tone may reflect ideas and(10) feelings over and above the words chosen, or may belie them. Here the conversant'stone can consciously or unconsciously reflect intuitive sympathy or antipathy, lack ofconcern or interest, fatigue, anxiety, enthusiasm or excitement, all of which are .usuallydiscernible by the acute listener. Public performance is a manner of communicationthat is highly specialized with its own techniques for obtainingeffects by voice and /or(15) gesture. The motivation derived from the text, and in the case of singing, the music, incombination with the performer's skills, personality, and ability to create empathy willdetermine the success of artistic, political, or pedagogic communication.Second, the voice gives psychological clues to a person'sself-image, perception ofothers, and emotional health. Self-image can be indicated by a tone of voice that is(20) confident, pretentious, shy, aggressive, outgoing, or exuberant, to name only a fewpersonality traits. Also the sound may give a clue to the facade or mask of that person,for example, a shy person hiding behind an overconfident front. How a speakerperceives the listener's receptiveness, interest, or sympathy in any given conversationcan drastically alter the tone of presentation, by encouraging or discouraging the(25) speaker. Emotional health is evidenced in the voice by free and melodic sounds of thehappy, by constricted and harsh sound of the angry, and by dull and lethargic qualitiesof the depressed34. What does the passage mainly discuss?(A) The function of the voice in performance(B) The connection between voice andpersonality(C) Communication styles(D) The production of speech35.

Industrialization and the bureaucratization of economicline life combined with a new emphasis upon credentials and expertise to make schooling(5) increasingly important for economic and social mobility. Increasingly, too, schoolswere viewed as the most important means of integrating immigrants into Americansociety.The arrival of a great wave of southern and eastern European immigrants at the turnof the century coincided with and contributed to an enormous expansion of formal(10) schooling. By 1920 schooling to age fourteen or beyond was compulsory in moststates, and the school year was greatly lengthened. Kindergartens, vacation schools,extracurricular activities, and vocational education and counseling extended theinfluence of public schools over the lives of students, many of whom in the largerindustrial cities were the children of immigrants. Classes for adult immigrants were(15) sponsored by public schools, corporations, unions, churches, settlement houses, andother agencies.Reformers early in the twentieth century suggested that education programs shouldsuit the needs of specific populations. Immigrant women were one such population.Schools tried to educate young women so they could occupy productive places in the(20) urban industrial economy, and one place many educators considered appropriate forwomen was the home.Although looking after the house and family was familiar to immigrant women,American education gave homemaking a new definition. In preindustrial economies,homemaking had meant the production as well as the consumption of goods, and it(25) commonly included income-producing activities both inside and outside the home,in the highly industrialized early-twentieth-century United States, however,overproduction rather than scarcity was becoming a problem. Thus, the ideal Americanhomemaker was viewed as a consumer rather than a producer. Schools trained womento be consumer homemakers cooking, shopping, decorating, and caring for children(30) "efficiently" in their own homes, or if economic necessity demanded, as employeesin the homes of others. Subsequent reforms have made these notions seem quiteout-of-date.44.
