TPO50阅读-1American Railroads原文 (1)译文 (2)题目 (3)答案 (8)背景知识 (9)原文American Railroads①In the United States,railroads spearheaded the second phase of the transportation revolution by overtaking the previous importance of canals.The mid-1800s saw a great expansion of American railroads.The major cities east of the Mississippi River were linked by a spiderweb of railroad tracks.Chicago's growth illustrates the impact of these rail links.In1849Chicago was a village of a few hundred people with virtually no rail service.By1860it had become a city of 100,000,served by eleven railroads.Farmers to the north and west of Chicago no longer had to ship their grain,livestock,and dairy products down the Mississippi River to New Orleans;they could now ship their products directly east.Chicago supplanted New Orleans as the interior of America's main commercial hub.②The east-west rail lines stimulated the settlement and agricultural development of the Midwest.By1860Illinois,Indiana,and Wisconsin had replaced Ohio, Pennsylvania,and New York as the leading wheat-growing states.Enabling farmers to speed their products to the East,railroads increased the value of farmland and promoted additional settlement.In turn,population growth in agricultural areas triggered industrial development in cities such as Chicago,Davenport(Iowa),and Minneapolis,for the new settlers needed lumber for fences and houses and mills to grind wheat into flour.③Railroads also propelled the growth of small towns along their routes.The Illinois Central Railroad,which had more track than any other railroad in1855, made money not only from its traffic but also from real estate speculation. Purchasing land for stations along its path,the Illinois Central then laid out towns around the stations.The selection of Manteno,Illinois,as a stop of the Illinois Central,for example,transformed the site from a crossroads without a single house in1854into a bustling town of nearly a thousand in1860,replete with hotels,lumberyards,grain elevators,and gristmills.By the Civil War(1861-1865), few thought of the railroad-linked Midwest as a frontier region or viewed its inhabitants as pioneers.④As the nation's first big business,the railroads transformed the conduct ofbusiness.During the early1830s,railroads,like canals,depended on financial aid from state governments.With the onset of economic depression in the late1830s, however,state governments scrapped overly ambitious railroad projects. Convinced that railroads burdened them with high taxes and blasted hopes,voters turned against state aid,and in the early1840s,several states amended their constitutions to bar state funding for railroads and canals.The federal government took up some of the slack,but federal aid did not provide a major stimulus to railroads before1860.Rather,part of the burden of finance passed to city and county governments in agricultural areas that wanted to attract railroads.Such municipal governments,for example,often gave railroads rights-of-way,grants of land for stations,and public funds.⑤The dramatic expansion of the railroad network in the1850s,however,strained the financing capacity of local governments and required a turn toward private investment,which had never been absent from the picture.Well aware of the economic benefits of railroads,individuals living near them had long purchased railroad stock issued by governments and had directly bought stock in railroads, often paying by contributing their labor to building the railroads.But the large railroads of the1850s needed more capital than such small investors could generate.Gradually,the center of railroad financing shifted to New York City,and in fact,it was the railroad boom of the1850s that helped make Wall Street in New York City the nation's greatest capital market.The stocks of all the leading railroads were traded on the floor of the New York Stock Exchange during the1850s.In addition,the growth of railroads turned New York City into the center of modern investment firms.The investment firms evaluated the stock of railroads in the smaller American cities and then found purchasers for these stocks in New York City,Philadelphia,Paris,London,Amsterdam,and Hamburg.Controlling the flow of funds to railroads,the investment bankers began to exert influence over the railroads'internal affairs by supervising administrative reorganizations in times of trouble.译文美国铁路①在美国，铁路超越了运河从前的重要性，成为运输革命第二阶段的先锋。

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.

TPO51托福阅读passage1：Origins of the Megaliths原文文本+真题答案
TPO51托福阅读passage1：Origins of the Megaliths原文文本+真题答案第一篇：考古类Origins of the MegalithsSince the days of the earliest antiquarians, scholars have been puzzled by the many Neolithic (~4000 B.C.~2200 B.C.) communal tombs known as megaliths alongEurope's Atlantic seaboard. Although considerable variations are found in the architectural form of these impressive monuments, there is a general overriding similarity in design and, particularly, in the use of massive stones.The construction of such large and architecturally complex tombs by European barbarians struck early prehistorians as unlikely. The Bronze Age seafaring civilizations that lived in the region of the Aegean Sea (~ 3000 B.C.~ 1000 B.C.), among whom collective burial and a diversity of stone-built tombs were known, seemed a probable source of inspiration. It was suggested that Aegean people had visited Iberia in southwestern Europe in search of metal ores and had introduced the idea of collective burial in massive tombs, which then spread northward to Brittany, Britain, North Germany, and Scandinavia.Radiocarbon dates for a fortified settlement of megalith builders at Los Millares in Spain appeared to confirm this picture, though dates for megaliths in Brittany seemed too early. When calibrated, however, it became clear that radiocarbon dates were universally too early to support a Bronze Age Aegean origin. It is now clear that the megaliths are a western and northern European invention, not an introduced idea. Even so, they are still a subject of speculation and inquiry. What induced their builders to invest massive efforts in erecting such monumental tombs? How was the necessary labor force assembled? What underliestheir striking similarities?One answer to the last question was proposed by Professor Grahame Clark, one ofBritain's greatest prehistorians. Investigating the megaliths of southern Sweden, he noted that one group was concentrated in coastal locations from which deep-sea fish such as cod, haddock, and ling could have been caught in winter. Historically, much of the Atlantic was linked by the travels of people who fished, and this could well have provided a mechanism by which the megalith idea and fashions in the style of tomb architecture spread between coastal Iberia, Brittany, Ireland, western England and Scotland, and Scandinavia. The high concentrations of megaliths on coasts and the surprising number of megaliths found on small islands may support a connection with fishing.Professor Colin Renfrew of the University of Cambridge, England, however, views the similarities as similar responses to similar needs. At the structural level, the passage that forms a major element of many graves could have been devised independently in different areas to meet the need for repeated access to the interior of these communal tombs. Other structural resemblances could be due to similarities in the raw materials available. In answer to the question of why the idea of building monumental tombs should arise independently in a number of areas, he cites the similarities in their backgrounds.Most megaliths occur in areas inhabited in the postglacial period by Mesolithic hunter-gatherers (~20000 B.C. ~ 18000 B.C. ). Their adoption of agriculture through contact with Neolithic farmers, Renfrew argues, led to a population explosion in the region and consequent competition for farmland between neighboring groups. Inthe face of potential conflict, the groups may have found it desirable to define their territories and emphasize their boundaries. The construction of megaliths could have arisen in response to this need.Renfrew has studied two circumscribed areas, the Scottish islands of Arran and Rousay, to examine this hypothesis more closely. He found that a division of the arable land into territories, each containing onemegalith, results in units that correspond in size to the individual farming communities of recent times in the same area. 【】Each unit supported between 10 and 50 people. 【】The labor needed to put up a megalith would probably be beyond the capabilities of a community this size. 【】But Renfrew argues that the cooperation of other communities could be secured by some form of recognized social incentive perhaps a period of feasting at which communal building was one of several activities. 【】Most megaliths contain collective burials. Different tombs used different arrangements, but there seems to have been an underlying theme: people placed in these tombs were representative of their society, but their identity as individuals was not important. The tombs belonged to the ancestors, through whom the living society laid claim to their land. This interpretation reinforces Renfrew’s view of the megaliths as territorial markers.题目1.The word "collective"in the passage is closest in meaning toA.above groundB.publicC.elaborateD.group2.According to paragraph 2, early prehistorians thought the Aegean people of the Bronze Age might have influenced megalith building along the Atlantic seaboard because theyA.had established commercial routes along the Atlantic seaboardB.had been in Iberia, where they introduced the idea of burial in very large tombsC.were thought to have found megaliths in Iberia when searching for metalsD.were thought to have passed along the concept of burial inmonumental tombs as they explored Brittany, Britain, North Germany, and ScandinaviaParagraph 2 is marked with3.In paragraph 3, why does the author discuss the results of radiocarbon dates?A.To support the idea that megaliths spread rapidly during the Bronze AgeB.To question the idea that megaliths have a religious originC.To provide evidence against the theory that Bronze Age Aegean inspired the megalithsD.To argue that the megaliths in Brittany are older than the megaliths in Los MillaresParagraph 3 is marked with4.The word "erecting" in the passage is closest in meaning toA.designingB.constructingC.protectingD.decorating5.According to paragraph 4, what did Professor Clark propose as a result of studying the megaliths of southern Sweden?A.Swedish megaliths are nearly identical to megaliths elsewhere.B.People who traveled for fishing may have been responsible for the spread of megaliths in Europe.C.Swedish megaliths were probably built after other European megaliths were built.D.Megaliths in Europe were usually located near sites for deep-sea fishing in winter.Paragraph 4 is marked with6.What is the purpose of discussing the passage that forms a major element of many graves?A.To provide an example of a commonly occurring feature of megaliths that might be related to a similar needB.To argue that similarities in raw materials were responsible for the similarity of passagesC.To explain how repeated access to the interior of the communal tombs was possibleD.To provide evidence that the builders of the megaliths had similar backgrounds Paragraph 5 is marked with7.The word "consequent" in the passage is closest in meaning toA.intenseB.increasingC.resultingD.continual8.According to paragraph 6, Professor Renfrew has argued that one factor leading to the rise of megaliths in Europe wasA.the adoption of farming by Mesolithic hunter-gatherersB.the transition from a glacial to a postglacial climateC.the relocation of Mesolithic populations from one region to anotherD.the conflict over whether areas inhabited by Mesolithic peoples would be used for farmingParagraph 6 is marked with9.The phrase style "this hypothesis" in the passage refers to the idea thatA.there was competition for territory between Mesolithic hunter-gathers and invading Neolithic farmersB.a population explosion brought about a division of the region's Neolithicfarmers into neighboring groupsC.the need of neighboring groups to define their territories led to the construction of megalithsD.the construction of megaliths was a way of competing for farmland10.According to paragraph 7, what did Renfrew conclude about the megaliths of Arran and Rousay?A.Each megalith was associated with a specific agricultural community.B.Each megalith was built by between 10 and 50 people.C.Some megaliths were built using stones quarried at other places.D.Some megaliths were built gradually over time rather than all at once.

托福TPO1阅读文本Part1TPO1 GroundwaterGroundwater is the word used to describe water that saturates the ground, filling all the available spaces. By far the most abundant type of groundwater is meteoric water; this is the groundwater that circulates as part of the water cycle. Ordinary meteoric water is water that has soaked into the ground from the surface, from precipitation (rain and snow) and from lakes and streams. There it remains, sometimes for long periods, before emerging at the surface again. At first thought it seems incredible that there can be enough space in the "solid" ground underfoot to hold all this water.The necessary space is there, however, in many forms. The commonest spaces are those among the particles-sand grains and tiny pebbles-of loose, unconsolidated sand and gravel. Beds of this material, out of sight beneath the soil, are common. They are found wherever fast rivers carrying loads of coarse sediment once flowed. For example, as the great ice sheets that covered North America during the last ice age steadily melted away, huge volumes of water flowed from them. The water was always laden with pebbles, gravel, and sand, known as glacial outwash, that was deposited as the flow slowed down.The same thing happens to this day, though on a smaller scale, wherever a sediment-laden river or stream emerges from a mountain valley onto relatively flat land, dropping its load as thecurrent slows: the water usually spreads out fanwise, depositing the sediment in the form of a smooth, fan-shaped slope. Sediments are also dropped where a river slows on entering a lake or the sea, the deposited sediments are on a lake floor or the seafloor at first, but will be located inland at some future date, when the sea level falls or the land rises; such beds are sometimes thousands of meters thick.In lowland country almost any spot on the ground may overlie what was once the bed of a river that has since become buried by soil; if they are now below the water's upper surface (the water table), the gravels and sands of the former riverbed, and its sandbars, will be saturated with groundwater.So much for unconsolidated sediments. Consolidated (or cemented) sediments, too, contain millions of minute water-holding pores. This is because the gaps among the original grains are often not totally plugged with cementing chemicals; also, parts of the original grains may become dissolved by percolating groundwater, either while consolidation is taking place or at any time afterwards. The result is that sandstone, for example, can be as porous as the loose sand from which it was formed.Thus a proportion of the total volume of any sediment, loose or cemented, consists of empty space. Most crystalline rocks are much more solid; a common exception is basalt, a form of solidified volcanic lava, which is sometimes full of tiny bubbles that make it very porous.The proportion of empty space in a rock is known as its porosity. But note that porosity is not the same as permeability, which measures the ease with which water can flow through a material; this depends on the sizes of the individual cavities and the crevices linking them.Much of the water in a sample of water-saturated sediment or rock will drain from it if the sample is put in a suitable dry place. But some will remain, clinging to all solid surfaces. It is held there by the force of surface tension without which water would drain instantly from any wet surface, leaving it totally dry. The total volume of water in the saturated sample must therefore be thought of as consisting of water that can, and water that cannot, drain away.The relative amount of these two kinds of water varies greatly from one kind of rock or sediment to another, even though their porosities may be the same. What happens depends on pore size. If the pores are large, the water in them will exist as drops too heavy for surface tension to hold, and it will drain away; but if the pores are small enough, the water in them will exist as thin films, too light to overcome the force of surface tension holding them in place; then the water will be firmly held.Paragraph 1: Groundwater is the word used to describe water that saturates the ground, filling all the available spaces.

Ordinary meteoric water is water that has soaked into the ground from the surface, from precipitation (rain and snow) and from lakes and streams.

Which of the following can be inferred from paragraph 1 about the ground that we walk on?○It cannot hold rainwater for long periods of time.○It prevents most groundwater from circulating.○It has the capacity to store large amounts of water.○It absorbs most of the water it contains from rivers.2. The word "incredible" in the passage is closest in meaning to○confusing○comforting○unbelievable○interestingParagraph 2: The necessary space is there, however, in many forms. The commonest spaces are those among the particles-sand grains and tiny pebbles-of loose, unconsolidated sand and gravel. Beds of this material, out of sight beneath the soil, are common.

According to paragraph 2, where is groundwater usually found?○Inside pieces of sand and gravel○On top of beds of rock○In fast rivers that are flowing beneath the soil○In spaces between pieces of sediment5. The phrase "glacial outwash" in the passage refers to○fast rivers○glaciers○the huge volumes of w ater created by glacial melting○the particles carried in water from melting glaciersParagraph 3: The same thing happens to this day, though on a smaller scale, wherever a sediment-laden river or stream emerges from a mountain valley onto relatively flat land, dropping its load as the current slows: the water usually spreads out fanwise, depositing the sediment in the form of a smooth, fan-shaped slope. Sediments are also dropped where a river slows on entering a lake or the sea, the deposited sediments are on a lake floor or the seafloor at first, but will be located inland at some future date, when the sea level falls or the land rises; such beds are sometimes thousands of meters thick.6. All of the following are mentioned in paragraph 3 as places that sediment-laden rivers can deposit their sediments EXCEPT ○A mountain valley○Flat land○A lake floor○The seafloorParagraph 4: In lowland country almost any spot on the ground may overlie what was once the bed of a river that has since become buried by soil; if they are now below the water's upper surface (the water table), the gravels and sands of the former riverbed, and its sandbars, will be saturated with groundwater.7. The word "overlie" in the passage is closest in meaning to○ cover○ change○ se parate○ surroundParagraph 5: So much for unconsolidated sediments. Consolidated (or cemented) sediments, too, contain millions of minute water-holding pores. This is because the gaps among the original grains are often not totally plugged with cementing chemicals; also, parts of the original grains may become dissolved by percolating groundwater, either while consolidation is taking place or at any time afterwards. The result is that sandstone, for example, can be as porous as the loose sand from which it was formed.8. The phrase "So much for" in the passage is closest in meaning to○that is enough about○now let us turn to○of greater concern are○this is related to9. The word "plugged" in the passage is closet in meaning to○washed○dragged○filled up○soaked throughParagraph 6: Thus a proportion of the total volume of any sediment, loose or cemented, consists of empty space. Most crystalline rocks are much more solid; a common exception is basalt, a form of solidified volcanic lava, which is sometimes full of tiny bubbles that make it very porous.Paragraph 7: The proportion of empty space in a rock isknown as its porosity. But note that porosity is not the same as permeability, which measures the ease with which water can flow through a material; this depends on the sizes of the individual cavities and the crevices linking them.10. According to paragraphs 6 and 7, why is basalt unlike most crystalline forms of rock?○It is unusually solid.○It often has high porosity.○It has a low proportion of empty space.○It is highly permeable.11. What is the main purpose of paragraph 7?○To explain why water can flow through rock○To emphasize the large amount of empty space in all rock ○To point out that a rock cannot be both porous and permeable○To distinguish between two related properties of rockParagraph 9: The relative amount of these two kinds of water varies greatly from one kind of rock or sediment to another, even though their porosities may be the same. What happens depends on pore size. If the pores are large, the water in them will exist as drops too heavy for surface tension to hold, and it will drain away; but if the pores are small enough, the water in them will exist as thin films, too light to overcome the force of surface tension holding them in place; then the water will be firmly held.12. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.○Surface tension is not strong enough to retain drops of water in rocks with large pores but it strong enough to hold onto thin films of water in rocks with small pores.○Water in rocks is held in place by large pores and drains away from small size pores through surface tension.○Small pores and large pores both interact with surface tension to determine whether a rock will hold water as heavy drops or as a thin film.○If the force of surface tension is too weak to hold water in place as heavy drops, the water will continue to be held firmly in place as a thin film when large pores exist.Paragraph 8: Much of the water in a sample of water-saturated sediment or rock will drain from it if the sample is put in a suitable dry place. But some will remain, clinging to all solid surfaces. It is held there by the force of surface tension without which water would drain instantly from any wet surface, leaving it totally dry. The total volume of water in the saturated sample must therefore be thought of as consisting of water that can, and water that cannot, drain away.13. Look at the four squares [] that indicate where the following sentence could be added to the passage.What, then, determines what proportion of the water stays and what proportion drains away?Where would the sentence best fit?14.

官方真题Official4托福阅读Passage1原文文本Deer Populations of the Puget SoundTwo species of deer have been prevalent in the Puget Sound area of Washington State in the Pacific Northwest of the United States. The black-tailed deer, a lowland, west-side cousin of the mule deer of eastern Washington, is now the most common. The other species, the Columbian white-tailed deer, in earlier times was common in the open prairie country; it is now restricted to the low, marshy islands and flood plains along the lower Columbia River.Nearly any kind of plant of the forest understory can be part of a deer's diet. Where the forest inhibits the growth of grass and other meadow plants, the black-tailed deer browses on huckleberry, salal, dogwood, and almost any other shrub or herb. But this is fair-weather feeding. What keeps the black-tailed deer alive in the harsher seasons of plant decay and dormancy? One compensationfor not hibernating is the built-in urge to migrate. Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall. Even with snow on the ground, the high bushy understory is exposed; also snow and wind bring down leafy branches of cedar, hemlock, red alder, andother arboreal fodder.The numbers of deer have fluctuated markedly since the entry of Europeans into Puget Sound country. The early explorers and settlers told of abundant deer in the early 1800s and yet almost in the same breath bemoaned the lack of this succulent game animal. Famous explorers of the north American frontier, Lewis and Clark arrived at the mouth of the Columbia River on November 14, 1805, in nearly starved circumstances. They had experienced great difficulty finding game west of the Rockies and not until the second of December did they kill their first elk. T o keep 40 people alive that winter, they consumed approximately 150 elk and 20 deer. And when game moved out of the lowlands in early spring, the expedition decided to return east rather than face possible starvation. Later on in the early years of the nineteenth century, when Fort Vancouver became the headquarters of the Hudson's Bay Company, deer populations continued to fluctuate. David Douglas, Scottish botanical explorer of the 1830s, found a disturbing change in the animal life around the fort during the period between his first visit in 1825 and his final contact with the fort in 1832. A recent Douglas biographer states:" The deer which once picturesquely dotted the meadows around the fort were gone [in 1832], hunted to extermination in order to protect the crops.Reduction in numbers of game should have boded ill for their survival in later times. A worsening of the plight of deer was to be expected as settlers encroached on the land, logging, burning, and clearing, eventually replacing a wilderness landscape with roads, cities, towns, and factories. No doubt the numbers of deer declined still further. Recall the fate of the Columbian white-tailed deer, now in a protected status. But forthe black-tailed deer, human pressure has had just the opposite effect. Wildlife zoologist Helmut Buechner(1953), in reviewing the nature of biotic changes in Washington through recorded time, says that "since the early 1940s, the state has had more deer than at any other time in its history, the winter population fluctuating around approximately 320,000 deer (mule and black-tailed deer), which will yield about 65,000 of either sex and any age annually for an indefinite period."The causes of this population rebound are consequences of other human actions. First, the major predators of deer—wolves, cougar, and lynx—have been greatly reduced in numbers. Second, conservation has been insured by limiting times for and types of hunting. But the most profoundreason for the restoration of high population numbers has been the fate of the forests. Great tracts of lowland country deforested by logging, fire, or both have become ideal feeding grounds of deer.In addition to finding an increase of suitable browse, like huckleberry and vine maple, Arthur Einarsen, longtime game biologist in the Pacific Northwest, found quality of browse in the open areas to be substantially more nutritive. The protein content of shade-grown vegetation, for example, was much lower than that for plants grown in clearings.官方真题Official4托福阅读Passage1题目Question 1 of 14According to paragraph 1, which of the following is true of the white-tailed deer of Puget Sound?A.

Deer populations reached their highest point during the 1940s and then began to decline.B. The activities of settlers contributed in unexpected ways to the growth of some deer populations in later times.C. The cleaning of wilderness land for construction caused biotic changes from which the black-tailed deer population has never recovered.D.

托福阅读真题1Cities develop as a result of functions that they can perform. Some functions result directly from the ingenuity of the citizenry, but most functions result from the needs of the local area and of the surrounding hinterland (the region that supplies goods to the city and to which the city furnishes services and other goods). Geographers often make a distinction between the situation and the site of a city. Situation refers to the general position in relation to the surrounding region, whereas site involves physical characteristics of the specific location. Situation is normally much more important to the continuing prosperity of a city. If a city is well situated in regard to its hinterland, its development is much more likely to continue. Chicago, for example, possesses an almost unparalleled situation: it is located at the southern end of a huge lake that forces east-west transportation lines to be compressed into its vicinity, and at a meeting of significant land and water transport routes. It also overlooks what is one of the worlds finest large farming regions. These factors ensured that Chicago would become a great city regardless of the disadvantageous characteristics of the available site, such as being prone to flooding during thunderstorm activity.Similarly, it can be argued that much of New York Citys importance stems from its early and continuing advantage of situation. Philadelphia and Boston both originated at about the same time as New York and shared New Yorks location at the western end of one of the worlds most important oceanic trade routes, but only New York possesses aneasy-access functional connection (the Hudson-Mohawk lowland) to the vast Midwestern hinterland. This account does not alone explain New Yorks primacy, but it does include several important factors. Among the many aspects of situation that help to explain why some cities grow and others do not, original location on a navigable waterway seems particularly applicable. Of course, such characteristic as slope, drainage, power resources, river crossings, coastal shapes, and other physical characteristics help to determine city location, but such factors are normally more significant in early stages of city development than later.1. What does the passage mainly discuss?(A) The development of trade routes through United States cities(B) Contrasts in settlement patterns in United States(C) Historical differences among three large United States cities(D) The importance of geographical situation in the growth of United States cities2. The word ingenuity in line 2. is closest in meaning to(A) wealth(B) resourcefulness(C) traditions(D) organization3.

According to the passage , a citys situation is more important than its site in regard to thecitys(A) long-term growth and prosperity(B) ability to protect its citizenry(C) possession of favorable weather conditions(D) need to import food supplies5. The author mentions each of the following as an advantage of Chicagos location EXCEPT its(A) hinterland(B) nearness to a large lake(C) position in regard to transport routes(D) flat terrain6. The word characteristics in line 14 is closest in meaning to(B) attitudes(C) qualities(D) inhabitants7. The primary purpose of paragraph 1 is to(A) summarize past research and introduce a new study(B) describe a historical period(C) emphasize the advantages of one theory over another(D) define a term and illustrate it with an example8.

The philosophy of the movement combined realism, ethnic consciousness, and Americanism. Encouraged by the example of certain Americans ofEuropean descent such as Thomas Eakins, Robert Henri, and George Luks, who had included persons of African descent in their paintings as serious studies rather than as trivial or sentimental stereotypes, African American artists of this period set about creating a new portrayal of themselves and their lives in the United States. As they began to strive for social and cultural independence. Their attitudes toward themselves changed, and, to some extent, other segments of American society began to change their attitudes toward them. Thus, though the Harlem Renaissance was a short-lived movement, its impact on American art and culture continues to the present.The district in New York City known as Harlem was the capital of the movement. In 1925 an issue of Survey Graphic magazine devoted exclusively to Harlem and edited by philosopher Alain Locke became the manifesto of the African American artistic movement. Locke strongly suggested that individuals, while accepting their Americanism, take pride in their African ancestral arts and urged artists to look to Africa for substance and inspiration. Far from advocating a withdrawal from American culture, as did some of his contemporaries, Locke recommended a cultural pluralism through which artists could enrich the culture of America. African Americans were urged by Locke to be collaborators and participators with other Americans in art, literature, and music; and at the same time to preserve, enhance, and promote their own cultural heritage.Artists and intellectuals from many parts of the United States and the Caribbean had been attracted to Harlem by the pulse and beat of its unique and dynamic culture. From this unity created by the convergence of artists from various social and geographical backgrounds came a new spirit, which, particularly in densely populated Harlem, was to result in greater group awareness and self-determination. African American graphic artists took their place beside the poets and writers of the Harlem Renaissance and carried on efforts to increase and promote the visual arts.1. What does the passage mainly discuss?(A) African American paintings in the 1920s(B) An arts movement of the 1920s(C) The influence of Alain Locke on African American art(D) Some ways in which African culture inspired American literature, art and music2. According to the passage , Tomas Eakins, Robert Henri, and George Luks were important because of(A) the philosophical contributions they made to the Harlem Renaissance(B) their development of a new style of African American art(C) they way in which they depicted African Americans in their paintings(D) their independence from European artistic traditions3. The word them in line 11 refers to(A) Americans of European descent(B) paintings(C) African American artists(D) attitudes4. According to the passage , African American artists of the 1920s differed from earlier AfricanAmerican artists in terms of their feelings about(A) themselves(B) other artists(C) their impact on American art(D) stereotypes5. The word urged in line 17 is closest in meaning to(A) prepared(B) defined(C) permitted(D) encouraged6. Alain Locke believed all of the following to be important to the African American artisticmovement EXCEPT(A) pride in African art(B) cultural pluralism(C) collaboration with other artists(D) withdrawal from American culture7. In mentioning the pulse and beat (line 25) of Harlem during the 1920s, the author ischaracterizing the district as one that(A) depended greatly on its interaction with other parts of the city(B) grew economically in a short period of time(C) was an exciting place to be(D) was in danger of losing population8. The word convergence in line 26 is closest in meaning to(A) gathering(B) promotion(C) expression(D) influence9. According to the passage , all of the following were true of Harlem in the 1920s EXCEPT:(A) Some Caribbean artists and intellectuals lived there.(B) It attracted people from various regions of United States.(C) It was one of the most expensive neighborhoods in New York City.(D) It was a unique cultural center.10. The phrase carried on in line 30 is closest in meaning to(A) continued(B) praised(C) transformed(D) connectedPASSAGE 72 BCCAD DCACA托福阅读真题3ffeterd spanning in line 18d- The interrelationship of science, technology, and industry is taken for granted today — summed up, not altogether accurately, as research and development. Yet historically this widespread faith in the economic virtues of science is a relatively recent phenomenon, dating back in the United States about 150 years, and in the Western world as a whole not over 300 years at most. Even in this current era of large scale, intensive research and development, the interrelationships involved in this process are frequently misunderstood. Until the coming of the Industrial Revolution, science and technology evolved for the most part independently of each other. Then as industrialization became increasingly complicated, the craft techniques of preindustrial society gradually gave way to a technology based on the systematic application of scientific knowledge and scientific methods. This changeover started slowly and progressed unevenly. Until late in the nineteenth century, only a few industries could use scientific techniques or cared about using them. The list expanded noticeably after 1870, but even then much of what passed for the application of science wasengineering science rather than basic science.Nevertheless, by the middle of the nineteenth century, the rapid expansion of scientific knowledge and of public awareness — if not understanding — of it had created a belief that the advance of science would in some unspecified manner automatically generate economic benefits. The widespread and usually uncritical acceptance of this thesis led in turn to the assumption that the application of science to industrial purposes was a linear process, starting with fundamental science, then proceeding to applied science or technology, and through them to industrial use. This is probably the most common pattern, but it is not invariable. New areas of science have been opened up and fundamental discoveries made as a result of attempts to solve a specific technical or economic problem. Conversely, scientists who mainly do basic research also serve as consultants on projects that apply research in practical ways.In sum, the science-technology-industry relationship may flow in several different ways, and the particular channel it will follow depends on the individual situation. It may at times even be multidirectional.1. What is the authors main purpose in the passage ?(A) To show how technology influenced basic science(B) To describe the scientific base of nineteenth-century American industries(C) To correct misunderstandings about the connections between science, technology, and industry(D) To argue that basic science has no practical application2. The word altogether in line 2 is closest in meaning to(A) completely(B) realistically(C) individually(D) understandably3. The word intensive in line 5 is closest in meaning to(A) decreased(B) concentrated(C) creative(D) advanced4. The list mentioned in line 13 refers to(A) types of scientific knowledge(B) changes brought by technology(C) industries that used scientific techniques(D) applications of engineering science5. The understanding of research and development in the late nineteenth century is based onwhich of the following?(A) Engineering science is not very important.(B) Fundamental science naturally leads to economic benefits.(C) The relationship between research and development should be criticized.(D) Industrial needs should determine what areas fundamental science focuses on.6. The word it in line 16 refers to(A) understanding(B) public awareness(C) scientific knowledge(D) expansion7. The word assumption in line 19 is closest in meaning to(A) regulation(B) belief(C) contract(D) confusion8. Why does the author mention consultants in line 25?(A) To show how new areas of science have given rise to new professions(B) To distinguish between scientists who work in industry and those who do not(C) To explain the ways in which scientists find financial support for their work(D) To show how scientists who work in basic research contribute to applied science9. Which of the following statements does the passage support?(A) The development of science and of industry is now interdependent.(B) Basic scientific research cannot generate practical applications.(C) Industries should spend less money on research and development.(D) Science and technology are becoming more separate.PASSAGE 73 CABCB CBDA托福阅读真题4Glaciers are large masses of ice on land that show evidence of past or present movement. They grow by the gradual transformation of snow into glacier ice.A fresh snowfall is a fluffy mass of loosely packed snowflakes, small delicate ice crystals grown in the atmosphere. As the snow ages on the ground for weeks or months, the crystals shrink and become more compact, and the whole mass becomes squeezed together into a more dense form, granular snow. As new snow falls and buries the older snow,the layers of granular snow further compact to form firm, a much denser kind of snow, usually a year or more old, which has little pore space. Further burial and slow cementation — a process by which crystals become bound together in a mosaic of intergrown ice crystals — finally produce solid glacial ice. In this process of recrystallization, the growth of new crystals at the expense of old ones, the percentage of air is reduced from about 90 percent for snowflakes to less than 20 percent for glacier ice. The whole process may take as little as a few years, but more likely ten or twenty years or longer. The snow is usually many meters deep by the time the lower layers are converted into ice.In cold glaciers those formed in the coldest regions of the Earth, the entire mass of ice is at temperatures below the melting point and no free water exists. In temperate glaciers, the ice is at the melting point at every pressure level within the glacier, and free water is present as small drops or as larger accumulations in tunnels within or beneath the ice.Formation of a glacier is complete when ice has accumulated to a thickness (and thus weight) sufficient to make it move slowly under pressure, in much the same way that solid rock deep within the Earth can change shape without breaking. Once that point is reached, the ice flows downhill, either as a tongue of ice filling a valley or as thick ice cap that flows out in directions from the highest central area where the most snow accumulates. The trip down leads to the eventual melting of ice.1. Which of the following does the passage mainly discuss?(A) The effect of glaciers on climate(B) Damage from glaciers(C) Glacier formation(D) The location of glaciers2. Which of the following will cause density within the glacier to increase?(A) Increased water and air content(B) Pressure from the weight of new snow(C) Long periods of darkness and temperature variations(D) Movement of the glacier3. The word bound in line 9 is closest in meaning to(A) covered(B) chosen(C) planned(D) held4. Which of the following will be lost is a glacier forms?(A) Air(B) Pressure(C) Weight(D) Rocks5. According to the passage , which of the following is the LEAST amount of time necessary forglacial ice to form?(A) several months(B) several years(C) at least fifty years(D) a century6. The word converted in line 15 is closest in meaning to(A) changed(B) delayed(C) promoted(D) dissolved7. What is the purpose of the material in paragraph three?(A) To define two types of glaciers(B) To contrast glacier ice with non-glacier ice(C) To present theories of glacier formation(D) To discuss the similarities between glacial types8. In temperate glaciers, where is water found?(A) Only near the surface(B) In pools of various depths(C) In a thin layer below the firm(D) In tunnels9.

托福阅读文本：Throughout the nineteenth century and into the twentieth, citizens of the United States maintained a bias against big cities. Most lived on farms and in small towns and believed cities to be centers of corruption, crime, poverty, and moral degradation. Their distrust was caused, in part,by a national ideology that proclaimed farming the greatest occupation and rural living superior to urban living. This attitude prevailed even as the number of urban dwellers increased and cities became an essential feature of the national landscape. Gradually, economic reality overcame ideology. Thousands abandoned the precarious life on the farm for more secure and better paying jobs in the city. But when these people migrated from the countryside, they carried their fears and suspicious with them. These new urbanities, already convinced that cities were overwhelmed with great problems, eagerly embraced the progressive reforms that promised to bring order out of the chaos of the city.One of many reforms came in the area of public utilities. Water and sewerage systems were usually operated by municipal governments, but the gas and electric networks were privately owned. Reformers feared that the privately owned utility companies would charge exorbitant rates for these essential services and deliver them only to people who could afford them. Some city and state governments responded by regulating the utility companies, but a number of cities began to supply these services themselves. Proponents of these reforms argued that public ownership and regulation would insure widespread access to these utilities and guarantee a fair price.While some reforms focused on government and public behavior, others looked at the cities as a whole. Civic leaders, convinced that physical environment influenced human behavior, argued that cities should develop master plans to guide their future growth and development. City planning was nothing new, but the rapid industrialization and urban growth of the late nineteenth century took place without any consideration for order. Urban renewal in the twentieth century followed several courses. Some cities introduced plans to completely rebuild the city core. Most other cities contented themselves with zoning plans for regulating future growth. Certain parts of town were restricted to residential use, while others were set aside for industrial or commercial development.托福阅读题目：1.
