托福TPO1-34阅读原文翻译:TPO-3-1：ArchitectureArchitecture is the art and science of designing structures that organize and enclose space for practical and symbolic purposes. Because architecture grows out of human needs and aspirations, it clearly communicates cultural values. Of all the visual arts, architecture affects our lives most directly for it determines the character of the human environment in major ways.Architecture is a three-dimensional form. It utilizes space, mass, texture, line, light, and color. To be architecture, a building must achieve a working harmony with a variety of elements. Humans instinctively seek structures that will shelter and enhance their way of life. It is the work of architects to create buildings that are not simply constructions but also offer inspiration and delight. Buildings contribute to human life when they provide shelter, enrich space, complement their site, suit the climate, and are economically feasible. The client who pays for the building and defines its function is an important member of the architectural team. The mediocre design of many contemporary buildings can be traced to both clients and architects.In order for the structure to achieve the size and strength necessary to meet its purpose, architecture employs methods of support that, because they are based on physical laws, have changed little since people first discovered them—even while building materials have changed dramatically. The world’s architectural structures have also been devised in relation to the objective limitations of materials. Structures can be analyzed in terms of how they deal with downward forces created by gravity. They are designed to withstand the forces of compression (pushing together), tension (pulling apart), bending, or a combination of these in different parts of the structure.Even development in architecture has been the result of major technological changes. Materials and methods of construction are integral parts of the design of architecture structures. In earlier times it was necessary to design structural systems suitable for the materials that were available, such as wood, stone, brick. Today technology has progressed to the point where it is possible to invent new building materials to suit the type of structure desired. Enormous changes in materials and techniques of construction within the last few generations have made it possible to enclose space with much greater ease and speed and with a minimum of material. Progress in this area can be measured by the difference in weight between buildings built now and those of comparable size built one hundred years ago.Modern architectural forms generally have three separate components comparable to elements of the human body:a supporting skeleton or frame, an outer skin enclosing the interior spaces, and equipment, similar to the body’s vital organs and systems. The equipment includes plumbing, electrical wiring, hot water, and air-conditioning. Of course in early architecture—such as igloos and adobe structures—there was no such equipment, and the skeleton and skin were often one.Much of the world’s great architecture has been constructed of stone because of its beauty, permanence, and availability. In the past, whole cities grew from the arduous task of cutting and piling stone upon. Some of the world’s finest stone architecture can be seen in the ruins of the ancient Inca city of Machu Picchu highin theeastern Andes Mountains of Peru. The doorways and windows are made possible by placing over the open spaces thick stone beams that support the weight from above. A structural invention had to be made before the physical limitations of stone could be overcome and new architectural forms could be created. That invention was the arch, a curved structure originally made of separate stone or brick segments. The arch was used by the early cultures of the Mediterranean area chiefly for underground drains, but it was the Romans who first developed and used the arch extensively in aboveground structures. Roman builders perfected the semicircular arch made of separate blocks of stone. As a method of spanning space, the arch can support greater weight than a horizontal beam. It works in compression to divert the weight above it out to the sides, where the weight is borne by the vertical elements on either side of the arch. The arch is among the many important structural breakthroughs that have characterized architecture throughout the centuries.译文：TPO-3-1 建筑物建筑是一门出于实用和象征的双重目的，通过组织和利用空间来实现设计结构的艺术和科学。

托福TPO1阅读真题原文Part3Timberline Vegetation on MountainsThe transition from forest to treeless tundra on a mountain slope is often a dramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line. In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.The upper timberline, like the snow line, is highest in the tropics and lowest in the Polar Regions. It ranges from sea level in the Polar Regions to 4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics. Timberline trees are normally evergreens, suggesting that these have some advantage over deciduous trees (those that lose their leaves) in the extreme environments of the upper timberline. There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach their greater heights in the valleys. This is because middle- and upper- latitude timberlinesare strongly influenced by the duration and depth of the snow cover. As the snow is deeper and lasts longer in the valleys, trees tend to attain greater heights on the ridges, even though they are more exposed to high-velocity winds and poor, thin soils there. In the tropics, the valleys appear to be more favorable because they are less prone to dry out, they have less frost, and they have deeper soils.There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline. Various environmental factors may play a role. Too much snow, for example, can smother trees, and avalanches and snow creep can damage or destroy them. Late-lying snow reduces the effective growing season to the point where seedlings cannot establish themselves. Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes. Some scientists have proposed that the presence of increasing levels of ultraviolet light with elevation may play a role, while browsing and grazing animals like the ibex may be another contributing factor. Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.Above the tree line there is a zone that is generally called alpine tundra. Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. Some plants can even survive in favorable microhabitats above the snow line. Thehighest plants in the world occur at around 6,100 meters on Makalu in the Himalayas. At this great height, rocks, warmed by the sun, melt small snowdrifts.The most striking characteristic of the plants of the alpine zone is their low growth form. This enables them to avoid the worst rigors of high winds and permits them to make use of the higher temperatures immediately adjacent to the ground surface. In an area where low temperatures are limiting to life, the importance of the additional heat near the surface is crucial. The low growth form can also permit the plants to take advantage of the insulation provided by a winter snow cover. In the equatorial mountains the low growth form is less prevalent.Paragraph 1: The transition from forest to treeless tundra on a mountain slope is often adramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line.

There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.4. Paragraph 2 supports which of the following statements about deciduous trees?○They cannot grow in cold climates.○They do not exist at the upper timberline.○They are less likely than evergreens to survive at the upper timberline.○They do not require as much moisture as evergreens do.Paragraph 3: At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach theirgreater heights in the valleys. This is because middle- and upper- latitude timberlines are strongly influenced by the duration and depth of the snow cover.

Which of the sentences below best express the essential information in the highlighted sentence in the passage? In correct choices change the meaning in important ways or leave out essential information.○Because of their deformed shapes at high altitudes, trees are not likely to be seriously harmed by the strong winds typical of those altitudes.○As altitude increases, the velocity of winds increase, leading to a serious decrease in the number of trees found at high altitudes.○The deformed shapes of trees at high altitu des show that wind velocity, which increase with altitude, can cause serious hardship for trees.○Increased wind velocity at high altitudes deforms the shapes of trees, and this may cause serious stress for trees.10. In paragraph 4, what is the author's main purpose in the discussion of the dramatic cessation of tree growth at the upper timberline?○To argue that none of several environment factors that are believed to contribute to that phenomenon do in fact play a role in causing it.○To argue in support of one particular explanation of that phenomenon against several competing explanations ○To explain why the primary environmental factor responsible for that phenomenon has not yet been identified ○To present several environmental factors that may contribute to a satisfactory explanation of that phenomenon Paragraph 6: The most striking characteristic of the plants of the alpine zone is their low growth form.

▉托福TPO1阅读Passage3原文文本： Groundwater Groundwater 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 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. 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. ▉托福TPO1阅读Passage3题目： Question 1 of 14 Which of the following can be inferred from paragraph 1 about the ground that we walk on? A. It cannot hold rainwater for long periods of time. B. It prevents most groundwater from circulating. C. It has the capacity to store large amounts of water. D. It absorbs most of the water it contains from rivers. Question 2 of 14 The word “incredible ” in the passage is closest in meaning to。

In earlier times it was necessary to design structural systems suitable for the materials that were available, such as wood, stone, brick. Today technology has progressed to the point where it is possible to invent new building materials to suit the type of structure desired. Enormous changes in materials and techniques of construction within the last few generations have made it possible to enclose space with much greater ease and speed and with a minimum of material. Progress in this area can be measured by the difference in weight between buildings built now and those of comparable size built one hundred years ago.Modern architectural forms generally have three separate components comparable to elements of the human body: a supporting skeleton or frame, an outer skin enclosing the interior spaces, and equipment, similar to the body's vital organs and systems. The equipment includes plumbing, electrical wiring, hot water, and air-conditioning. Of course in early architecture-such as igloos and adobe structures-there was no such equipment, and the skeleton and skin were often one.Much of the world's great architecture has been constructedof stone because of its beauty, permanence, and availability. In the past, whole cities grew from the arduous task of cutting and piling stone upon. Some of the world's finest stone architecture can be seen in the ruins of the ancient Inca city of Machu Picchu high in the eastern Andes Mountains of Peru. The doorways and windows are made possible by placing over the open spaces thick stone beams that support the weight from above. A structural invention had to be made before the physical limitations of stone could be overcome and new architectural forms could be created. That invention was the arch, a curved structure originally made of separate stone or brick segments. The arch was used by the early cultures of the Mediterranean area chiefly for underground drains, but it was the Romans who first developed and used the arch extensively in aboveground structures. Roman builders perfected the semicircular arch made of separate blocks of stone. As a method of spanning space, the arch can support greater weight than a horizontal beam. It works in compression to divert the weight above it out to the sides, where the weight is borne by the vertical elements on either side of the arch. The arch is among the many important structural breakthroughs that have characterized architecture throughout the centuries.Paragraph 1: Architecture is the art and science of designing structures that organize and enclose space for practical and symbolic purposes. Because architecture grows out of human needs and aspirations, it clearly communicates cultural values. Of all the visual arts, architecture affects our lives most directly for it determines the character of the human environment in major ways.托福TPO3阅读真题Part1题目1. According to paragraph 1, all of the following statements about architecture are true EXCEPT:○Architecture is visual art.○Architecture reflects the cultural values of its creators.○Architecture has both artistic and scientific dimensions.○Architecture has an indirect effect on life.Paragraph 2: Architecture is a three-dimensional form. It utilizes space, mass, texture, line, light, and color. To be architecture, a building must achieve a working harmony with a variety of elements. Humans instinctively seek structures that will shelter and enhance their way of life. It is the work of architects to create buildings that are not simply constructions but also offer inspiration and delight. Buildings contribute to human life when they provide shelter, enrich space, complement their site, suit the climate, and are economically feasible. The client who pays for the building and defines its function is an important member of the architectural team. The mediocre design of many contemporary buildings can be traced to both clients and architects.2.The word "feasible" in the passage is closest in meaning to○in existence○without question○achievable○most likely3. The word "enhance" in the passage is closest in meaning to○protect○improve○organize○matchParagraph 3: In order for the structure to achieve the size and strength necessary to meet its purpose, architecture employs methods of support that, because they are based on physical laws, have changed little since people first discovered them-even while building materials have changed dramatically. The world's architectural structures have also been devised in relation to the objective limitations of materials. Structures can be analyzed in terms of how they deal with downward forces created by gravity. They are designed to withstand the forces of compression (pushing together), tension (pulling apart), bending, or a combination of these in different parts of the structure.4. 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.○Unchanging physical laws have limited the size and strength of buildings that can be made with materials discovered long ago.○Building materials have changed in order to increase architectural size and strength, but physical laws of structure have not changed.○When people first started to build, the structural methods used to provide strength and size were inadequate because they were not based on physical laws.○Unlike building materials, the methods of support used in architecture have not changed over time because they are based on physical laws.5. The word "devised" in the passage is closest in meaning to○combined○created○introduced○suggestedParagraph 4: Even development in architecture has been the result of major technological changes. Materials and methods of construction are integral parts of the design of architecture structures. In earlier times it was necessary to design structural systems suitable for the materials that were available, such as wood, stone, brick. Today technology has progressed to the point where it is possible to invent new building materials to suit the type of structure desired. Enormous changes in materials and techniques of construction within the last few generations have made it possible to enclose space with much greater ease and speed and with a minimum of material. Progress in this area can be measured by the difference in weight between buildings built now and those of comparable size built one hundred years ago.6. The word "integral" is closest in meaning to○essential○variable○practical○independent7. According to paragraph 4, which of the following is true about materials used in the construction of buildings?○Because new building materials are hard to find, construction techniques have changed very little from past generations.○The availability of suitable building materials no longer limits the types of structures that may be built.○The primary building materials that are available today are wood, stone, and brick.○Architects in earlier times did not have enough buildingmaterials to enclose large spaces.8. In paragraph 4, what does the author imply about modern buildings?○They occupy much less space than buildings constructed one hundred years ago.○They are not very different from the building of a few generations ago.○They weigh less in relation to their size than buildings constructed one hundred years ago.○They take a long time to build as a result of their complex construction methods.Paragraph 5: Modern architectural forms generally have three separate components comparable to elements of the human body: a supporting skeleton or frame, an outer skin enclosing the interior spaces, and equipment, similar to the body's vital organs and systems. The equipment includes plumbing, electrical wiring, hot water, and air-conditioning. Of course in early architecture-such as igloos and adobe structures-there was no such equipment, and the skeleton and skin were often one.9. Which of the following correctly characterizes the relationship between the human body and architecture that is described in paragraph 5?○Complex equipment inside buildings is the one element in modern architecture that resembles a component of the human body.○The components in ea rly buildings were similar to three particular elements of the human body.○Modern buildings have components that are as likely to change as the human body is.○In general, modern buildings more closely resemble the human body than earlier buildings do.Paragraph 6: Much of the world's great architecture has been constructed of stone because of its beauty, permanence, and availability. In the past, whole cities grew from the arduous task of cutting and piling stone upon. Some of the world's finest stone architecture can be seen in the ruins of the ancient Inca city of Machu Picchu high in the eastern Andes Mountains of Peru.

It works in compression to divert the weight above it out to the sides, where the weight is borne by the vertical elements on either side of the arch. The arch is among the many important structural breakthroughs that have characterized architecture throughout the centuries.10. The word "arduous" in the passage is closest in meaning to○difficult○necessary○skilled○shared11. Why does the author include a description of how the "doorways and windows" of Machu Picchu were constructed?○To indicate that the combined skeletons and skins of the stone buildings of Machu Picchu were similar to igloos and adobe structures○To indicate the different kinds of stones that had to be cut to build Machu Picchu○To provide an illustration of the kind of construction that was required before arches were invented○To explain how ancient builders reduced the amount of time necessary to construct buildings from stone12.According to paragraph 6, which of the following statements is true of the arch?○The Romans were the first people to use the stone arch.○The invention of the arch allowed new architectural forms to be developed.○The arch worked by distributing the structural load of a building toward the center of the arch.○The Romans followed earlier practices in their use of arches.Paragraph 5: █Modern architectural forms generally have three separate components comparable to elements of the human body; a supporting skeleton or frame, an outer skin enclosing the interior spaces, and equipment, similar to the body's vital organs and systems. █The equipment includes plumbing, electrical wiring, hot water, and air-conditioning. █Of course in early architecture-such as igloos and adobe structures-there was no such equipment, and the skeleton and skin were often one. █13.Look at the four squares [█] that indicate where thefollowing sentence could be added to the passage.However, some modern architectural designs, such as those using folded plates of concreter or air-inflated structures, are again unifying skeleton and skin.Where would the sentence best fit?14.Directions: An introductory sentence for a brief summary of the passage is provided below.

托福TPO1口语Task3阅读文本： Letter in the Centerville College News The administration has plans to acquire a new sculpture for campus. We should all oppose this plan. The university's poor financial condition led it to increase the price for campus housing and tuition by 15% this past year. Surely then it is no financial position to purchase such an expensive sculpture. Moreover, just look at the sculpture: several 60-foot ling steel plates, jutting out of the earth at odd angles! It's so large, it'll take up all the green space in front of the campus center! This is public space that should be reserved for students to use. 托福TPO1口语Task3听力文本： Now listen to two students discussing the opinion expressed in the letter.(man) Did you see Paul's letter in the paper about the new sculpture?(woman) Yeah, but it was totally unconvincing. His reasons for opposing the plan are just totally off.I am glad that we'll finally have some nice art on campus. I'd like to shake the donor's hand and say “thank you.”(man) What do you mean the donor?(woman) You didn't know? An anonymous donor is paying the bill for most of the sculpture.(man) Not the university?(woman) No! His assumptions about who's paying are all wrong!(man) Still, I wonder if he has a point about the space it'll take up?(woman) Well, you know why Paul is upset. He and his friends are always out there on the lawn right where the sculpture will be, kicking around the soccer ball. Now they'll just have to use another part of the campus to play.(man) Oh! So he just doesn't want to have to move.(woman) Yeah! For him, it's sculpture versus convenience. 托福TPO1口语Task3题目： Explain why the woman disagrees with the reasons expressed in the letter. 托福TPO1口语Task3满分范文： Well, the woman disagrees with the reasons and points made in the letter for some reasons. First of all, the woman believes that the money wouldn't be a problem and the assumption in the letter is totally wrong, since an anonymous donor is paying the bill for most of the sculptures instead of the university. And she disagrees with the advice made in the letter because she thinks that the lawn taken for the sculptures will only upset Paul alone instead of other students, simply because Paul has to move to other places of the campus for his ball-playing. In a word, the woman disagrees with the letter for the reasons stated above. (116 words) 以上是给大家整理的托福TPO1口语Task3阅读文本+听力文本+题目+满分范文，希望对你有所帮助!。
托福阅读tpo 1 Timberline Vegetation on Mountains原题解析
阅读原文：The transition from forest to treeless tundra on a mountain slope is often a dramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line. In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.通常从山坡上的森林到没有树的苔原是一种非常戏剧化的转变。
在一个垂直距离只有几十米的地方，树木这种生命形式就消失了，取而代之的是低矮的灌木、草本植物和牧草。
这种快速过渡的区域被称为上行树带界线或林木线。
在许多干旱的地区存在着下行树带界线，在这里由于缺乏水分森林变成干草原，甚至在最下端会出现沙漠。
The upper timberline, like the snow line, is highest in the tropics and lowest in the Polar Regions. It ranges from sea level in the Polar Regions to 4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics. Timberline trees are normally evergreens, suggesting that these have some advantage over deciduous trees (those that lose their leaves) in the extreme environments of the upper timberline. There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.上行树带界线，和雪线一样，在热带最高，在极地最低。

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. The passage suggests that a geographer would consider a citys soil type part of its(B) situation(C) site(D) function4. 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. According to the passage , Philadelphia and Boston are similar to New York City in(A) size of population(B) age(C) site(D) availability of rail transportation9. The word functional in line 20 is closest in meaning to(A) alternate(B) unknown(C) original(D) usable10. The word it in line 21 refers to(A) account(B) primacy(C) connection(D) hinterland11. The word significant in line 26 is closest in meaning to(A) threatening(B) meaningful(C) obvious(D) availablePASSAGE 71 DBCAD CDCDA B托福阅读真题2The Harlem Renaissance, a movement of the 1920s, marked the twentieth centurys first period of intense activity by African Americans in the field of literature, art, and music in the United States. 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.

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.

托福TPO1阅读真题原文Part3Timberline Vegetation on MountainsThe transition from forest to treeless tundra on a mountain slope is often a dramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line. In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.The upper timberline, like the snow line, is highest in the tropics and lowest in the Polar Regions. It ranges from sea level in the Polar Regions to 4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics. Timberline trees are normally evergreens, suggesting that these have some advantage over deciduous trees (those that lose their leaves) in the extreme environments of the upper timberline. There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach their greater heights in the valleys. This is because middle- and upper- latitude timberlines are strongly influenced by the duration and depth of the snow cover. As the snow is deeper and lasts longer in the valleys, trees tend to attain greater heights on the ridges, even though they are more exposed to high-velocity winds and poor, thin soils there. In the tropics, the valleys appear to be more favorable because they are less prone to dry out, they have less frost, and they have deeper soils.There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline. Various environmental factors may play a role. Too much snow, for example, can smother trees, and avalanches and snow creep can damage or destroy them. Late-lying snow reducesthe effective growing season to the point where seedlings cannot establish themselves. Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes. Some scientists have proposed that the presence of increasing levels of ultraviolet light with elevation may play a role, while browsing and grazing animals like the ibex may be another contributing factor. Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.Above the tree line there is a zone that is generally called alpine tundra. Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. Some plants can even survive in favorable microhabitats above the snow line. The highest plants in the world occur at around 6,100 meters on Makalu in the Himalayas. At this great height, rocks, warmed by the sun, melt small snowdrifts.The most striking characteristic of the plants of the alpine zone is their low growth form. This enables them to avoid the worst rigors of high winds and permits them to make use of the higher temperatures immediately adjacent to the ground surface. In an area where low temperatures are limiting to life, the importance of the additional heat near the surface is crucial. The low growth form can also permit the plants to take advantage of the insulation provided by a winter snow cover. In the equatorial mountains the low growth form is less prevalent.Paragraph 1: The transition from forest to treeless tundra on a mountain slope is often adramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line. In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.托福TPO1阅读真题题目Part31. The word "dramatic" in the passage is closest in meaning to○gradual○complex○visible○striking2. Where is the lower timberline mentioned in paragraph 1 likely to be found?○In an area that has little water○In an area that has little sunlight○Above a transition area○On a mountain that has on upper timberline.3. Which of the following can be inferred from paragraph 1 about both the upper and lower timberlines?○Both are treeless zones.○Both mark forest boundaries.○Both are surrounded by desert areas.○Both suffer from a lack of moisture.Paragraph 2: The upper timberline, like the snow line, is highest in the tropics and lowest in the Polar Regions. It ranges from sea level in the Polar Regions to4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics. Timberline trees are normally evergreens, suggesting that these have some advantage over deciduous trees (those that lose their leaves) in the extreme environments of the upper timberline. There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.4. Paragraph 2 supports which of the following statements about deciduous trees?○They cannot grow in cold climates.○They do not exist at the upper timberline.○They are less likely than evergreens to survive at the upper timberline.○They do no t require as much moisture as evergreens do.Paragraph 3: At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach their greater heights in the valleys. This is because middle- and upper- latitude timberlines are strongly influenced by the duration and depth of the snow cover. As the snow is deeper and lasts longer in the valleys, trees tend to attain greater heights on the ridges, even though they are more exposed to high-velocity winds and poor, thinsoils there. In the tropics, the valleys appear to be more favorable because they are less prone to dry out, they have less frost, and they have deeper soils.5. The word "attain" in the passage is closest in meaning to○require○resist○achieve○endure6. The word "they" in the passage refers to○valleys○trees○heights○ridges7. The word "prone" in the passage is closest in meaning to○adapted○likely○difficult○resistant8. According to paragraph 3, which of the following is true of trees in the middle and upper latitudes?○Tree growth is negatively affected by the snow cover in valleys○Tree growth is greater in valleys than on ridges.○Tree growth on ridges is not affected by high-velocity winds.○Tree growth lasts longer in those latitudes than it does in the tropics.Paragraph 4：There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline. Various environmental factors may play a role. Too much snow, for example, can smother trees, and avalanches and snow creep can damage or destroy them. Late-lying snow reduces the effective growing season to the point where seedlings cannot establish themselves. Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes. Some scientists have proposed that the presence of increasing levels of ultraviolet light with elevation may play a role, while browsing and grazing animals like the ibex may be another contributing factor. Probably the most important environmental factoris temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.9. Which of the sentences below best express the essential information in the highlighted sentence in the passage? In correct choices change the meaning in important ways or leave out essential information.○Because of their deformed shapes at high altitudes, trees are not likely to be seriously harmed by the strong winds typical of those altitudes.○As altitude increases, the velocity of winds increase, leading to a serious decrease in the number of trees found at high altitudes.○The deformed shapes of trees at high altitudes show that wind velocity, which increase with altitude, can cause serious hardship for trees.○Increased wind velocity at high altitudes deforms the shapes of trees, and this may cause serious stress for trees.10. In paragraph 4, what is the author's main purpose in the discussion of the dramatic cessation of tree growth at the upper timberline?○To argue that none of several environment factors that are believed to contribute to that phenomenon do in fact play a role in causing it.○To argue in support of one particular explanation of that phenomenon against several competing explanations○To explain why the primary environmental factor responsible for that phenomenon has not yet been identified○To present several environmental factors that may contribute to a satisfactory explanation of that phenomenonParagraph 6: The most striking characteristic of the plants of the alpine zone is their low growth form. This enables them to avoid the worst rigors of high winds and permits them to make use of the higher temperatures immediately adjacent to the ground surface. In an area where low temperatures are limiting to life, the importance of the additional heat near the surface is crucial. The low growth form can also permit the plants to take advantage of the insulation provided by a winter snow cover. In the equatorial mountains the low growth form is lessprevalent.11. The word "prevalent" in the passage is closest in meaning to○predictable○widespread○successful○developed12. According to paragraph 6, all of the following statements are true of plants in the alpine zone EXCEPT:○Because they are low, they are less exposed to strong winds.○Because they are low, the winter snow cover gives them more protection from the extreme cold.○In the equatorial mountains, they tend to be lower than in mountai ns elsewhere.○Their low growth form keeps them closer to the ground, where there is more heat than further up.Paragraph 5: Above the tree line there is a zone that is generally called alpine tundra. █Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. █Some plants ca n even survive in favorable microhabitats above the snow line. The highest plants in the world occur at around 6,100 meters on Makalu in the Himalayas. █At this great height, rocks, warmed by the sun, melt small snowdrifts. █13. Look at the four squares [█] that indicate where the following sentence could be added to the passage.This explains how, for example, alpine cushion plants have been found growing at an altitude of 6,180 meters.Where would the sentence best fit?14.
