Passage 1 Megafauna Extinctions in Ancient Australia古澳大利亚大型哺乳动物的灭绝（重复2018.12.01）话题重复2018.03.11 The Australian Megafauna Extinctions。

生物史上大型动物的灭绝在各个地方情况有所不同。

而究其灭绝原因，科学家提出了两种说法，一是climate，一是认为hunt。

Passage 2 The Formation of Early Earth早期地球的形成（首考新题）Passage 3 Colonial America and the Navigation Acts 殖民时期的美国和航海法案（重复2015.03.07）先讲了早期英国殖民者对美洲的殖民引起了一些不满，因为收税过高且限制他们的一些产品与英国竞争。

后面着重讲其实这种殖民统治也对美国经济有好处，如帮他们买产品到欧洲，有英国海军保护等。

最后说美国农民虽然参与市场经济，但前提还是满足自己，所以也会通过生产来和别人换。

Passage 4 Mexican Mural Art墨西哥壁画艺术（重复2015.09.19）第一段：壁画艺术出现及原因分析。

2019年5月26日托福阅读考试真题及解析最新一期的托福考试已经圆满结束，这次的考试引发了大家的热议。

今天就和一起看看2019年5月26日托福阅读考试真题及解析。

Passage1 Isolation and Diversification in the Tropical Rainforest热带雨林物种隔离与多样性（重复2016.07.10）热带雨林物种多，那里的植被超过1000种，欧洲有40种。

由于大平原的动物要走很久才能寻找到合适的生活地点，热带雨林的动物不能，他们被限制在有限的空间内，所以热带雨林物种很多。

热带雨林里的屏障阻碍动物们的扩散，描述了如何阻碍。

树冠（canopy）是热带雨树中浓密的树叶和枝干各种交织形成的，动物们很难突破这层canopy，只能在最高层的这层canopy之下活动，所以无法扩散到外界。

所以限制在内的植物们就多样化（diversify）。

50-70米是超级高的且喜阳光的树种们为了晒太阳浴而拼命生长突破最高canopy形成的。

因此有种s鸟就生活在这里，他们可以去任何地方，所以列举了三个州有这种鸟，而且种类较少，他们俯瞰着森林。

紧接着讲k这种树，因为突破canopy长得高，可以将种子散播更远，于是south American都有这种树。

Passage 2 The Theories of Megafauna Extinction大型动物灭绝理论（重复2018.08.26，2017.01.07）讲的是某一时期哺乳动物大范围灭绝的原因：先说可能是由于气候变化，但是文章后面进行了否定，因为之前也有气候变化，但是也没有灭绝。

然后猜测和人类捕杀有关，但澳洲等一些地方的考古证明一些灭绝的动物已经和人类和平共处了上千年，而且一些人类更爱捕杀的动物如reindeer反而没有灭绝。

最后说人类活动间接导致了这些动物的灭绝。

Passage 3 Flightless Bird不会飞的鸟（重复2019.01.26，2018.03.10）岛屿上退化掉飞行能力的鸟。

Memphis:United Egypt's First Capital[1]The city of Memphis,located on the Nile near the modern city of Cairo,was founded around 3100 B.C.as the first capital of a recently united Egypt.The choice of Memphis by Egypt's first kings reflects the site's strategic importance.■First,and most obvious,the apex of the Nile River delta was a politically opportune location for the state's administrative center,standing between the united lands of Upper and Lower Egypt and offering ready access to both parts of the country.The older predynastic(pre-3100BC)centers of power,This and Hierakonpolis,were too remote from the vast expanse of the delta,which had been incorporated into the united state.■Only a city within easy reach of both the Nile valley to the south and the more spread out,difficult terrain to the north could provide the necessary political control that the rulers of early dynastic Egypt(roughly 3000-2600 B.C.)required.■[2]The region of Memphis must have also served as an important node for transport and communications,even before the unification of Egypt.The region probably acted as a conduit for much,if not all,of the river-based trade between northern and southern Egypt.■Moreover,commodities(such as wine,precious oils,and metals)imported from the Near East by the royal courts of predynastic Upper Egypt would have been channeled through the Memphis region on their way south.In short,therefore,the site of Memphis offered the rulers of the Early Dynastic Period an ideal location for controlling internal trade within their realm,anessential requirement for a state-directed economy that depended on the movement of goods.[3]Equally important for the national administration was the ability to control communications within Egypt.The Nile provided the easiest and quickest artery of communication,and the national capital was,again,ideally located in this respect.Recent geological surveys of the Memphis region have revealed much about its topography in ancient times.It appears that the location of Memphis may have been even more advantageous for controlling trade,transport,and communications than was previously appreciated.Surveys and drill cores have shown that the level of the Nile floodplain has steadily risen over the last five millenniums.When the floodplain was much lower,as it would have been in predynastic and early dynastic times,the outwash fans(fan-shaped deposits of sediments)of various wadis(stream-beds or channels that carry water only during rainy periods)would have been much more prominent features on the east bank.The fan associated with the Wadi Hof extended a significant way into the Nile floodplain,forming a constriction in the vicinity of Memphis.The valley may have narrowed at this point to a mere three kilometers,making it the ideal place for controlling river traffic.[4]Furthermore,the Memphis region seems to have been favorably located for thecontrol not only of river-based trade but also of desert trade routes.The two outwash fans in the area gave access to the extensive wadi systems of the eastern desert.In predynastic times,the Wadi Digla may have served as a trade route between the Memphis region and the Near East,to judge from the unusual concentration of foreign artifacts found in the predynasticsettlement of Maadi.Access to,and control of,trade routes between Egypt and the Near East seems to have been a preoccupation of Egypt's rulers during the period of state formation.The desire to monopolize foreign trade may have been one of the primary factors behind the political unification of Egypt.The foundation of the national capital at the junction of an important trade route with the Nile valley is not likely to have been accidental.Moreover,the Wadis Hof and Digla provided the Memphis region with accessible desert pasturage.As was the case with the cities of Hierakonpolis and Elkab,the combination within the same area of both desert pasturage and alluvial arable land(land suitable for growing crops)was a particularly attractive one for early settlement;this combination no doubt contributed to the prosperity of the Memphis region from early predynastic times.1.The word"trivial"in the passage is closest in meaning toA.similarB.inaccurateC.smallD.significantParagraph 1 is marked with?答案：C选项正确解析：本题为词汇题，根据所给单词trivial定位到第一段More important than the amount of time Herodotus computed,which turns out to be trivial compared with the age of Earth,was the notion that one could estimate ages of geologic features by determining rates of the processes responsible for such features,and then assuming the rates to be roughly constant overtime.本句大致意思为：与地球的年龄相比，Herodotus这个人计算出来的时间量是trivial的，与其相比更重要的是一个概念，这个概念是一个人可以通过估计相应地理特征的某种过程的速度来估计地理特征的年龄……再以Herodotus为关键词定位这个time是什么，找到本段第三句，发现他是推测Nile Delta花了几千年形成的。

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. 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.托福TPO1阅读题目Part11. 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. 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.3. The word "out of sight" in the passage is closest in meaning to○far away○hidden○partly visible○discovered4. 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.

The fort had become the headquarters for the Hudson's Bay Company.B. Deer had begun populating the meadows around the fort.C. Deer populations near the fort had been destroyed.D. Crop yields in the area around the fort had decreased.Question 7 of 14Why does the author ask readers to recall “the fate of the Columbian white-tailed deer ” in the discussion of changes in the wilderness landscape?A. To provide support for the idea that habitat destruction would lead to population declineB. To compare how two species of deer caused biotic changes in the wilderness environmentC. To provide an example of a species of deer that has successfully adapted to human settlementD. To argue that some deer species must be given a protected statusQuestion 8 of 14The phrase “indefinite period ” in the passage is closest in meaning to periodA. whose end has not been determinedB. that does not begin when expectedC. that lasts only brieflyD. whose importance remains unknownQuestion 9 of 14Which of the following statements about deer populations is supported by the information in paragraph 4?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. Since the 1940s the winter populations of deer have fluctuated more than the summer populations have.Question 10 of 14The word “rebound ” in the passage is closest in meaning toA. declineB. recoveryC. exchangeD. movementQuestion 11 of 14Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?

Arthur Einarsen’s longtime family with the Pacif ic Northwest helped him discover areas where deer had an increase in suitable browse.B. Arthur Einarsen found that deforested feeding grounds provided deer with more and better food.C. Biologist like Einarsen believe it is important to findadditional open areas with suitable browse for deer to inhabit.D. According to Einarsen, huckleberry and vine maple are examples of vegetation that may someday improve the nutrition of deer in the open areas of the Pacific Northwest.Question 12 of 14Which of the following is NOT mentioned in paragraph 5 as a factor that has increased deer populations?A. A reduction in the number of predatorsB. Restrictions on huntingC. The effects of logging and fireD. Laws that protected feeding grounds of deerQuestion 13 of 14Look at the four squares [■] that indicate where the following sentence could be added to the passage. Where would the sentence best fit?There food is available and accessible throughout the winter..Question 14 of 14Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that not presented in the passage or are minor ideas in the passage. This question is worth 2 points. Deer in the Puget Sound area eat a wide variety of foods and migrate seasonally to find food.A.The balance of deer species in the Puget Sound region has changed over time, with the Columbian white-tailed deer now outnumbering other types of deer.B.Deer populations naturally fluctuate, but early settlers in the Puget Sound environment caused an overall decline in thedeer populations of the areas at that time.C.In the long term, black-tailed deer in the Puget Sound area have benefitted from human activities through the elimination of their natural predators, and more and better food in deforested areas.D.Because Puget Sound deer migrate, it was and still remains difficult to determine accurately how many deer are living at any one time in the western United States.E.Although it was believed that human settlement of the American West would cause the total number of deer to decrease permanently, the opposite has occurred for certain types of deer.F.Wildlife biologists have long been concerned that the loss of forests may create nutritional deficiencies for deer.官方真题Official4托福阅读Passage1解析Question 1 of 14正确答案：D题目解析：以White-tailed deer做关键词定位至最后一句：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.说白尾鹿过去是什么什么地方的，现在是什么什么地方的，也就是它们的生活环境发生了变化，所以D不再在原来的地方生活正确。

2012年11月10日托福阅读真题解析

2012年11月10日托福阅读真题解析第一篇：EARTH AGE第一篇是讲的早期科学家们估计地球寿命。

首先说人们很早就在预估地球寿命了；之后一段讲的近代一位科学家采用生物一代代进化速度的方式预估了三叠纪的长度，但基于的假设是进化速率基本相同，其估计已经有一定准确度了。

后来讲科学家利用这种方式预估地球寿命，其弱点是有部分化石找不到而且更基本的错误是地球在生物诞生之前那段时间无法估计。

（这里有插空题）之后讲了科学家用其他方式预估，有种是采用测算地壳沉积岩石厚度的方法，但问题是没有考虑板块运动以及腐蚀。

另一种是计算海水盐度发，理想地认为一开始地球海洋是淡水，不断地填充盐才有了现在这样子，但这也忽略了盐分与海底大陆架之间的复杂作用以及其他（这里会考题问科学家忽略了什么）。

但作者对于科学家基于盐度推出的几千万年的寿命还是给予肯定的。

因为这已经验证了地球寿命远比原先预计的几百万年要多得多。

而且也有一批科学家从其他领域验证了这个结果。

The age of the Earth is 4.54 ± 0.05 billion years.This age is based on evidence from radiometric age dating of meteorite material and is consistent with the ages of theoldest-known terrestrial and lunarsamples. Following the scientific revolution and the development of radiometric age dating, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old.Because the exact accretion time of Earth is not yet known, and the predictions from different accretion models range from a few millions up to about 100 million years, the exact age of Earth is difficult to determine. It is also difficult to determine the exact age of the oldest rocks on Earth, exposed at the surface, as they are aggregates of minerals of possibly different ages.【岩层研究法】Studies of strata, the layering of rocks and earth, gave naturalists an appreciation that Earth may have been through many changes during its existence. These layers often contained fossilized remains of unknown creatures, leading some to interpret a progression of organisms from layer to layer.In the 1790s, the British naturalist William Smith hypothesized that if two layers of rock at widely differing locations contained similar fossils, then it was very plausible thatthe layers were the same age. William Smith's nephew and student, John Phillips, later calculated by such means that Earth was about 96 million years old.The naturalist Mikhail Lomonosov, regarded as the founder of Russian science, suggested in the mid-18th century that Earth had been created separately from the rest of the universe, several hundred thousand years before. Lomonosov's ideas were mostly speculative, but in 1779, the French naturalist the Comte du Buffon tried to obtain a value for the age of Earth using an experiment: He created a small globe that resembled Earth in composition and then measured its rate of cooling. This led him to estimate that Earth was about 75,000 years oldIn 1862, the physicist William Thomson （who later became Lord Kelvin）of Glasgow published calculations that fixed the age of Earth at between 20 million and 400 million years. He assumed that Earth had formed as a completely molten object, and determined the amount of time it would take for the near-surface to cool to its present temperature. His calculations did not account for heat produced via radioactive decay （a process then unknown to science）or convection inside the Earth, which allows more heat to escape from the interior to warm rocks near the surface.【生物进化方法】Geologists had trouble accepting such a short age for Earth. Biologists could accept that Earth might have a finite age, but even 100 million years seemed much too short to be plausible. Charles Darwin, who had studied Lyell's work, had proposed his theory of the evolution of organisms by natural selection, a process whose combination of random heritable variation and cumulative selection implies great expanses of time. （Geneticists have subsequently measured the rate of genetic divergence of species, using the molecular clock, to date the last universal ancestor of all living organisms no later than 3.5 to 3.8 billion years ago）。

0308托福试题阅读（55minutes）Question 1-11If food is allowed to stand for some time, it putrefies .When the putrefied materialis examined microscopically ,it is found to be teeming with bacteria. Where do thesebacteria come from , since they are not seen in fresh food? Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 )generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structures present in air closely resemble the microorganisms seen in putrefying materials .He did(10)this by passing air through guncotton filters, the fibers of which stop solid particles. Afterthe guncotton was dissolved in a mixture of alcohol and ether, the particles that it hadtrapped fell to the bottom of the liquid and were examined on a microscope slide .Pasteurfound that in ordinary air these exists a variety of solid structures ranging in size from0.01 mm to more than 1.0 mm .Many of these bodiesresembled the reproductive(15)structures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedfrom the organized bodies present in the air .He postulated that these bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary forspontaneous generation and that the air inside the sealed flask was affected in some way(25)by heating so that it would no longer supportspontaneous generation. Pasteur constructed a swan-necked flask in which putrefying materials could he heated to boiling, but aircould reenter. The bends in the neck prevented microorganisms from getting in the flask.. Material sterilized in such a flask did not putrefy.1,What does the passage mainly discuss?(a)Pasteur’s influence on the development of the microscope.(b)The origin of the theory of spontaneous generation .(c)The effects of pasteurization on food.(d)Pasteur’s argument against the theory of spontaneous generation .2,The phrase “teeming with ”in line 2 is closest in meaning to(a)full of(b)developing into(c)resistant to(d)hurt by3,Which of the following questions did the theory of spontaneous generation attempt to answer?(a)What is the origin of the living organisms are seen onsome food?(b)How many types of organisms can be found on food?(c)What is the most effective way to prepare living organisms for microscopic examination?(d)How long can food stand before it putrefies?4,The word “resemble” in line 9 is closest in meaning to(a)benefit from(b)appear similar to(c)join together with(d)grow from5,The purpose of the “guncotton” mentioned in paragraph 2 was to(a)trap particles for analysis(b)slow the process of putrefaction(c)increase the airflow to the microscopic slide(d)aid the mixing of alcohol and ether6,The author mention “1.0mm”in line 14 in describing the (a)thickness of a layer of organisms that was deposited on an object(b)diameter of the fibers that were in the guncotton filters(c)thickness of the microscope slides that were used(d)size of the particles that that were collected7.The word “postulated”in line 19 is closest in meaning to(a)analyzed(b)doubted(c)persuaded(d)suggested8.The objects that Pasteut removed from the air in his experiment were remarkable because they were(a)primarily single-celled organisms(b)no different from objects found in putrefying materials(c)fairly rare(d)able to live in a mixture of alcohol and ether9.The word “it” in line 22 refers to(a)a nutrient solution(b)a glass flask(c)boiling(d)spontaneous generation10.According to paragraph 3,proponents of spontaneous generation believed that which of the following was important for the process to succeed ?(a)A sealed container(b)Fresh air(c)Heat(d)The presence of nutrients11.It can be inferred from paragraph 3 that Pasteur employeda swam-necked flask to(a)store sterilized liquids for use in future experiments(b)prevent heat from building up in a solution(c)disprove a criticism of his conclusions(d)estimate the number of organisms in a liter of air Questions 12-20In the early decades of the United States ,the agrarian movement promoted the farmeras society’s hero. In the minds of agrarian thinkers and writers ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,which ended in 1865 ,was the age of(5 )the farmer in the United States .Agrarian philosophers ,represented most eloquently byThomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a goodsociety, their political virtue ,and their Superior morality .And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10)all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15) launched exploring expeditions into prospective farmlands in the West .In addition ,government trade policies facilitated the exporting of agricultural products.For their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20)more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops andpure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunning rapidity .But farmers responded(25)less to the expectations of agrarians and governmentinducements than to growing market opportunities .European demand for food from the United States seemed insatiable . War, industrialization , and urbanization all kept demand high in Europe . United States citiesand industries grew as well; even industries not directly related to farming thrived becauseof the market, money ,and labor that agriculture provided .12.What does the passage mainly discuss?(a)The agrarian philosophy of Thomas Jefferson(b)The role of the national government in the development of agriculture(c)Improvements in farming techniques(d)The impact of the increased importance of the farmer13.The word “depended” in line 3 is closest in meaning to(a)improved(b)relied(c)demanded(d)explained14.The author mentions Thomas Jefferson in paragraph 1 as an example of(a)a leader during the Revolution(b)an inventor of new farming techniques(c)a philosopher who believed farmers were essential to the creation of a good society(d)a farmer who guided the agrarian movement toward an emphasis on economic development15.The phrase “subscribed to” in line 8 is closest in meaning to(a)contributed to(b)agreed with(c)thought about(d)expanded on16.Which of the following statements is supported by the information in paragraph 1?(a)All government policy makers accepted Jefferson’s views of agriculture and farmers.(b)Agricultural production declined between 1783 and 1861.(c)The majority of farmers worked for the government.(d)Agricult ure was a vital part of the nation’s economy.17.According to the passage , the national and state governments did all of the following EXCEPT(a)build roads(b)import new plant varieties(c)give farmers money for their crops(d)develop policies that helped farmers export their products18.All of the following are mentioned as examples of farmers’ meeting the expectations of agrarian philosophers EXCEPT(a)obtaining information from farm newspapers(b)accumulating personal wealth(c)planting new crops(d)becoming more scientific19.The word “stunning” in line 24 is closest in meaning to(a)predictable(b)impressive(c)famous(d)gradual20.Which of the following statements is best supported by paragraph 4?(a)Agricultural development contributed to development in other parts of the economy.(b)European agricultural products were of a higher quality than those produced in the United States.(c)The growing settlement of the West led to a decrease in agricultural production.(d)Farmers were influenced more by government policies than by market opportunities.Question 21-29The wide variety of climates in North America has helped spawn a complex pattern ofsoil regions. In general, the realm’s soils also reflect the broad environmental partitioninginto “humid America” and “arid America.” Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher in acidcontent) nor alkaline(higher in saltcontent).fertilization is necessary to achieve the desired level of neutrality between thetwo. Arid America’s soils are typically alkaline and must be fertilized back towardneutrality by adding acidic compounds. Although many of these dryland soils, particularlyin the Great Plains, are quite fertile, European settlers learned over a century ago that(10) water is the main missing ingredient in achieving their agricultural potential. In the1970’s, certain irrigation methods were perfected and finally provided a real opportunityto expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15)and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but theenormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20)the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleafdeciduous trees as one crosses the(25)border into the Northeast United States. As oneproceeds toward the Southeast, broadleaf vegetation becomes dominant. Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.21 What aspect of North America does the passage mainly discuss?(A) The wide variety of climates(B) Soil types and vegetation patterns(C) Improved irrigation methods and the expansion ofagriculture(D) The change in precipitation patterns22 The word “spawn ” in line 1 is clo sest in meaning to(A) distinguish(B) eliminate(C) protect(D) create23 The word “partitioning” in line 2 is closest in meaning to(A) division(B) modification(C) opening(D) circulating24 According to the passage, acidic soils tent to be associated with(A) a high salt content(B) an increase in farming(C) large amounts of rain(D) glacial meltwater25 The word “enhanced” in line 13 is closest in meaning to(A) implied(B) increased(C) indicated(D) informed26 How did glacial meltdown affect the soil in North America?(A) It redistributed the soil types(B) It added salt to the soil(C) It made the soil more neutral in content(D) It added minerals to the soil27 The phrase “this regionalization scheme” in line 19 refers to the(A) movements of glacial deposits(B) patterns of natural vegetation(C) human modification of the North American environment(D) distinction between humid America and arid America28 The word “transition” in line 23 is closest in meaning to(A) elevation(B) change(C) advantage(D) condition29 The passage supports which of the following statements?(A) Arid America is not necessarily characterized by thepresence of deserts(B) Most of Canada and the northeastern United Statesconsists of short-grass prairies wherever natural vegetation has not been modified by humans(C) The accumulation of loess is primarily the result ofirrigation(D) Glaciation removed the fertile layer of soil from muchof the Mississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second), the human eye will not reactin time to see the object. A photographic emulsion---that is, a light-sensitive coating on photographic film, paper, or glass---will, however, record much shorter bursts of light. A(5 )photographic flash can therefore be used to capturehigh-speed movement on film as wellas to correct deficiencies of the normal surroundinglighting. Photoflash is now generated electronically, butthe earliest form, first used in 1864, was a paper bagcontainingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When thebag was ignited, the metal burned with an intense flash.A contemporary observer reported(10) that “this quite unsafe device seems to have donenothing worse that engulf the room indense smoke and lead to pictures of dubious quality andodd poses.”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of being ignited in an atmosphere of pure oxygen at low pressure,were introduced only in the 1920’s. In the earliest type,the metal(15) was separated from the oxygen by a thin glass bulb. Theflash was fired by piercing thebulb and allowing the oxygen to come into contact withthe metal, which ignitedspontaneously. Later bulbs were fired by an electricbattery, which heated the wire bypassing a small current through it. Other combinations,such as the pairing of oxygendifluoride with zirconium, have also been used. In eachcase enough energy is given out to(20)heat the oxidizable metal momentarily to a white-hotemission of visible light. The smoke particles are so small that they cool rapidly; but sincethey are white, they contribute to the brilliance byreflecting the light from their still-glowing neighbors.A slightly bigger formof the metal will burn for a longer time.30 What does the passage mainly discuss?(A) The history of the photoflash(B) Theories about how the eye reacts to light(C) The technology of modern photography(D) The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A) recording of an image on film(B) generation of artificial light(C) creation of a photographic emulsion(D) human eye to react to light32 According to the passage, an advantage of using a photoflash is that it(A) can produce repeated bursts of light(B) intensities colors in photographs(C) is short enough not to bother human eyes(D) supplements existing lighting33 The w ord “ignited” in line 9 is closest in meaning to(A) set on fire(B) cut into(C) opened(D) shaken34 Which of the following phrases is defined in paragraph 1?(A)”appreciable period”(line 1)(B)”photographic emulsion”(line 3)(C)”high-speed movement”(li ne 5)(D)”odd poses”(line 11)35 The word “evolution” in line 12 is closest in meaning to(A) publicity(B) adoption(C) development(D) manufacture36 The function of the glass in the first flashbulbs was to(A) produce the spark that initiated the flash(B) magnify the light produced by the flash(C) protect the photographer from the heat of the flash(D) keep the metal and oxygen apart before the flash37 The word “it” in line 18 refers to(A) oxygen(B) battery(C) wire(D) current38 The word “momentarily” in line 20 is closest in meaning to(A) effortlessly(B) briefly(C) electronically(D) gradually39 According to the passage, the white color of the smoke particles generated by a flashbulb contributes to(A) rapid cooling(B) bright illumination(C) electrical conductivity(D) intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A) thicker wire(B) more oxygen(C) thinner glass(D) continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’s. The Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. They concentrated onthe play of light over objects, people, and nature, breaking up seemingly solid surfaces,(5 ) stressing vivid contrast between colors in sunlight andshade, and depiction reflected lightin all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and then moving indoorsto complete the work form memory.(10) Some of the Impressionists’ painting methods were affected by technologicaladvances. For example, the shift from the studio to the open air was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finish their paintings on the spot.(15) Impressionism acquired its name not from supporters but from angry art lovers whofelt threatened by the new painting. The term “Impressionism” was born in 1874,whena group of artists who had been working together organized an exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintings exhibited was one called(20)Impression: Sunrise, by Claude Monet(1840-1926),Viewedthrough hostile eyes,Monet’s painting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste. Borrowing Monet’s title, art critics extended the term “Impressionism” to the entire exhibit. In response, Monet and his 29 fellow artists inthe exhibit adopted the same name as a badge of their unity, despite individual differences.(25) From then until 1886 Impressionism had all the zeal ofa “church”, as the painter Renoirput it. Monet was faithful to the Impressionist creed until his death, although many of theothers moved on to new styles.41 What aspect of painting in the nineteenth century does the passage mainly discuss?(A) The impact of some artists’ resistance to the fastpace of life(B) The differences between two major styles of art(C) A technological advance in the materials used byartists(D) A group of artists with a new technique and approach toart42 The word “depict” in line 2 is closest in meaning to(A) reorganize(B) deform(C) represent(D) justify43 According to the passage, which of the following was one of the distinguishing characteristics of Impressionist painting?(A) The emphasis on people rather than nature scenes(B) The way the subjects were presented from multipleangles(C) The focus on small solid objects(D) The depiction of the effects of light and color44 Which of the following is a significant way in which Impressionists were different from the artists that preceded them?(A) They began by making sketches of their subjects(B) They painted their subjects out-of-doors(C) They preferred to paint from memory(D) They used subjects drawn from modern life45 The word “advent” in line 12 is closest in meaning to(A) achievement(B) acceptance(C) arrival(D) advantage46 The exhibition of paintings organized in 1874 resulted in all of the following EXCEPT(A) attracting attention from the public(B) a negative reaction from the press(C) an immediate demand for the paintings exhibited(D) creating a name for a new style of painting47 The word “affront” in line 22 is closest in meaning to(A) insult(B) encouragement(C) return(D) credit48 The rejection of the Impressionist exhibition by critics was caused by which of the following?(A) The small number of paintings on display(B) Lack of interest in exhibitions by young artists(C) The similarity between all the paintings exhibited(D) Anger about seemingly poorly painted art49 The author mentions Renoir in line 25 to give an example of an artist who(A) became as famous as Monet(B) was consistently praised by art critics(C) described the enthusiasm of the Impressionists fortheir work(D) was in favor of a traditional style of painting50 The word “others” in line 27 refers to(A) art critics(B) fellow artists(C) individual differences(D) new styles0308答案ABADB CCCBA BDDCC DCDBA DACCB DBCAC DACBA BABDC BCAAD CDABA CACCB CDBCB DACCC ABCDA CDCDC BDCDC BCDDC DBACBDAABA DDBAB CDBCB DCBBA BDACB DDBAA DDABC DCBBA DCDBC CADCB。

TPO53托福阅读Passage1原文文本Questions About A Drama ClassListen to a conversation between a student and his drama professor.Professor: Hi Robert. So how's your paper going?Robert: Pretty well. It's a lot of work, but I’m getting into it, so I don't mind. I’ll probably have some questions for you in the next week or so.Professor: Okay. Glad to hear you’re progressing so well.Robert: Um… There was something you said at the end of the lecture on Tuesday, something about there not really being any original plays.Professor: There’s no such thing as an origi nal play. Yes. That's the direct quote from Charles Mee.Robert: Mee… that's with two “e”s, right?Professor: Yep. M-E-E. You'll probably be hearing a lot about him. He's becoming a pretty famous playwright.Robert: Yeah，well, I’ve been thinking about his quote. I mean there must be some original plays out there.Professor: I’ll grant that he's overstating things somewhat. But the theater does have a long tradition of borrowing. Take Shakespeare. Like most writers of his day, he borrowed plots from other sources unabashedly. And the ancient Greeks, all the plays they wrote were based on earlier plays, poems and myths.Robert: And borrowing applies to plays being written nowadays, too?Professor: T o some extent, yes. Mee, for example, he's made a career out o f remaking plays, one of which we’ll be studying soon. It’s called Full Circle and Mee based it on an earlier play by a German playwright.Robert: Oh Full Circle… Wasn't that based on the Caucasian Chalk Circle?Professor: That's right.Robert: I remember hearing about that play from my acting coach.Professor: Okay. Well, the Caucasian Chalk Circle was based on a play by yet another German playwright, someone who was fascinated by the ancient literatures of China, India and Persia, and many of his works were adapted from those literatures, including his version of the Chalk Circle which was based on an early Chinese play.Robert: So this Full Circle play, by Charles Mee, the one we're going to study, it's like the third or fourth remake. Wow… And we complain that Hollywood keeps making the same movies over and over again.Professor: Well, part of what Mee’s trying to do is drive home the point that: One, theater’s always a collaborative effort.Robert: Well, yeah, the playwright, the director, the actors, people have to work together to produce a play.Professor: Yes, of course. But Mee means historically. The dramatic literature of early periods is hugely influential in shaping later dramatic works.Robert: So it's like when the playwright bases a play on a previous playwright's theme or message.It's like they're talking toeach other, collaborating. Uh, just not at the same time right?Professor: Exactly. And the second point Mee's trying to make, I think, is that it's legitimate to retell an old story in a new way, in a way that’s, uh… more in line with contemporary concerns. So when playwrights reinvent or update an earlier play, it shouldn't be construed as a lack of imagination or an artistic failure.TPO53托福阅读Passage1题目Question 1 of 5Why does the man go to see the professor?A. To discuss a play he heard aboutB. To get feedback on a paper he is writingC. To ask about a point made in classD. To get information about an acting coachQuestion 2 of 5Why does the professor mention Shakespeare and the ancient Greek playwrights?A. To support her statement that some original plays do existB. To show that playwrights historically have used themes from earlier playsC. To point out that Shakespeare was greatly influenced by ancient Greek playsD. To give examples of playwrights whose plays have inspired later playwrightsQuestion 3 of 5What does the professor imply about the play Full Circle by Charles Mee?A. It served as the basis for a Hollywood film.B. It is indirectly based on a Chinese play.C. It has influenced a more recent play.D. It uses themes from ancient Greek literature.Question 4 of 5What two points does Charles Mee make about playwriting? Click on 2 answersA. Rewriting old plays to deal with modern issues is a respectable practice.B. Playwrights should preserve as much of the original as possible when updating an older play.C. Older plays tend to show more imagination than newer plays.D. In a way, modern playwrights work with playwrights of the past.Question 5 of 5What does the man imply when he says this:A. He thinks the professor misunderstood his point.B. He has written some original plays himself.C. He doubts that what Charles Mee said is true.D. He has read some original plays by Charles Mee.TPO53托福阅读Passage1解析正确答案：C题目解析：本题定位到原文：Robert: Um… There was something you said at the end of the lecture on Tuesday, something about there're not really being any original plays. 此处原文的大意是：学生提到教授上节课说其实没有完全原创的戏剧。

▉托福TPO24阅读Passage1原文文本：Lake WaterWhere does the water in a lake come from,and how does water leave it?Water enters a lake from inflowing rivers,from underwater seeps and springs,from overland flow off the surrounding land,and from rain falling directly on the lake surface.Water leaves a lake via outflowing rivers,by soaking into the bed of the lake,and by evaporation.So much is obvious.The questions become more complicated when actual volumes of water are considered:how much water enters and leaves by each route?Discovering the inputs and outputs of rivers is a matter of measuring the discharges of every inflowing and outflowing stream and river.Then exchanges with the atmosphere are calculated by finding the difference between the gains from rain,as measured(rather roughly)by rain gauges,and the losses by evaporation,measured with models that correct for the other sources of water loss.For the majority of lakes,certainly those surrounded by forests,input from overland flow is too small to have a noticeable effect.Changes in lake level not explained by river flows plus exchanges with the atmosphere must be due to the net difference between what seeps into the lake from the groundwater and what leaks into the groundwater.Note the word"net":measuring the actual amounts of groundwater seepage into the lake and out of the lake is a much more complicated matter than merely inferring their difference.Once all this information has been gathered,it becomespossible to judge whether a lake’s flow is mainly due to its surface inputs and outputs or to its underground inputs and outputs.If the former are greater,the lake is a surface-water-dominated lake;if the latter,it is a seepage-dominated lake.Occasionally,common sense tells you which of these two possibilities applies.For example,a pond in hilly country that maintains a steady water level all through a dry summer in spite of having no streams flowing into it must obviously be seepage dominated.Conversely,a pond with a stream flowing in one end and out the other,which dries up when the stream dries up,is clearly surface water dominated.By whatever means,a lake is constantly gaining water and losing water:its water does not just sit there,or,anyway,not for long.This raises the matter of a lake’s residence time.The residence time is the average length of time that any particular molecule of water remains in the lake,and it is calculated by dividing the volume of water in the lake by the rate at which water leaves the lake.The residence time is an average;the time spent in the lake by a given molecule(if we could follow its fate)would depend on the route it took:it might flow through as part of thefastest,most direct current,or it might circle in a backwater for an indefinitely long time.Residence times vary enormously.They range from a few days for small lakes up to several hundred years for large ones;Lake Tahoe,in California,has a residence time of 700 years.The residence times for the Great Lakes of North America,namely,Lakes Superior,Michigan,Huron,Erie,and Ontario,are,respectively,190,100,22,2.5,and 6 /doc/7b4002097.html,ke Erie’s is th elowest:although its area is larger than Lake Ontario’s,its volume is less than one-third as great because it is so shallow-less than20 meters on average.A given lake’s residence time is by no means a fixed quantity.It depends on the rate at which water enters the lake,and that depends on the rainfall and the evaporation rate.Climatic change(the result of global warming?)is dramatically affecting the residence times of some lakes in northwestern Ontario,Canada.In the period 1970 to 1986,rainfall in the area decreased from 1,000 millimeters to 650 millimeters per annum,while above-average temperatures speeded up the evapotranspiration rate(the rate at which water is lost to the atmosphere through evaporation and the processes of plant life).The result has been that the residence time of one of the lakes increased from 5 to 18 years during the study period.The slowing down of water renewal leads to a chain of further consequences;it causes dissolved chemicals to become increasingly concentrated,and this,in turn,has a marked effect on all living things in the lake.paragraph1:Where does the water in a lake come from,and how does water leave it?Water enters a lake from inflowing rivers,from underwater seeps and springs,from overland flow off the surrounding land,and from rain falling directly on the lake surface.Water leaves a lake via outflowing rivers,by soaking into the bed of the lake,and by evaporation.So much is obvious.▉托福TPO24阅读Passage1题目：1.The phrase So much in the passage refers to○the negative eff ects of overland flow,rain,and evaporation on river water levels○water that a lake loses to outflowing rivers,to the lakebed,and to evaporation○the importance of rivers to the maintenance of lake water levels○the information given about ways that water can enter or exit a lake。

It has been estimated that an additional one-fourth of the Earth's land surface is threatened by this process.Desertification is accomplished primarily through the loss of stabilizing natural vegetation and the subsequent accelerated erosion of the soil by wind and water. In some cases the loose soil is blown completely away, leaving a stony surface. In other cases, the finer particles may be removed, while the sand-sized particles are accumulated to form mobile hills or ridges of sand.Even in the areas that retain a soil cover, the reduction of vegetation typically results in the loss of the soil's ability to absorb substantial quantities of water. The impact of raindrops on the loose soil tends to transfer fine clay particles into the tiniest soil spaces, sealing them and producing a surface that allows very little water penetration. Water absorption is greatly reduced; consequently runoff is increased, resulting in accelerated erosion rates. The gradual drying of the soil caused by its diminished ability to absorb water results in the further loss of vegetation, so that a cycle of progressive surface deterioration is established.In some regions, the increase in desert areas is occurring largely as the result of a trend toward drier climatic conditions. Continued gradual global warming has produced an increase in aridity for some areas over the past few thousand years. The process may be accelerated in subsequent decades if global warming resulting from air pollution seriously increases.There is little doubt, however, that desertification in most areas results primarily from human activities rather than natural processes. The semiarid lands bordering the deserts exist in a delicate ecological balance and are limited in their potential to adjust to increased environmental pressures. Expanding populations are subjecting the land to increasing pressures to provide them with food and fuel. In wet periods, the land may be able to respond to these stresses. During the dry periods that are common phenomena along the desert margins, though, the pressure on the land is often far in excess of its diminished capacity, and desertification results.Four specific activities have been identified as major contributors to the desertification processes: overcultivation, overgrazing, firewood gathering, and overirrigation. The cultivation of crops has expanded into progressively drier regions as population densities have grown. These regions are especially likely to have periods of severe dryness, so that crop failures are common. Since the raising of most crops necessitates the prior removal of the natural vegetation, crop failures leave extensive tracts of land devoid of a plant cover and susceptible to wind and water erosion.The raising of livestock is a major economic activity in semiarid lands, where grasses are generally the dominant type of natural vegetation. The consequences of an excessive number oflivestock grazing in an area are the reduction of the vegetation cover and the trampling and pulverization of the soil. This is usually followed by the drying of the soil and accelerated erosion.Firewood is the chief fuel used for cooking and heating in many countries. The increased pressures of expanding populations have led to the removal of woody plants so that many cities and towns are surrounded by large areas completely lacking in trees and shrubs. The increasing use of dried animal waste as a substitute fuel has also hurt the soil because this valuable soil conditioner and source of plant nutrients is no longer being returned to the land.The final major human cause of desertification is soil salinization resulting from overirrigation. Excess water from irrigation sinks down into the water table. If no drainage system exists, the water table rises, bringing dissolved salts to the surface. The water evaporates and the salts are left behind, creating a white crustal layer that prevents air and water from reaching the underlying soil.The extreme seriousness of desertification results from the vast areas of land and the tremendous numbers of people affected, as well as from the great difficulty of reversing or even slowing the process. Once the soil has been removed by erosion, only the passage of centuries or millennia will enable new soil to form. In areas where considerable soil still remains, though, a rigorously enforced program of land protection and cover-crop planting may make it possible to reverse the present deterioration of the surface.Paragraph 1: The deserts, which already occupy approximately a fourth of the Earth's land surface, have in recent decades been increasing at an alarming pace. The expansion ofdesertlike conditions into areas where they did not previously exist is called desertification. It has been estimated that an additional one-fourth of the Earth's land surface is threatened by this process.托福TPO2阅读真题题目Part11.

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.

```0308 托福试题阅读（ 55minutes）Question 1-11If food is allowed to stand for some time, itputrefies .When the putrefied materialis examined microscopically ,it is found to be teeming withbacteria. Where do thesebacteria come from , since they are not seen in fresh food? Even until the mid-nineteenthcentury, many people believed that such microorganisms originated by spontaneous(5 ) generation ,a hypothetical process by which living organisms develop from nonlivingmatter.The most powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structurespresent in air closely resemble the microorganisms seen in putrefying materials .He did(10)this by passing air through guncotton filters, the fibers of which stop solid particles. Afterthe guncotton was dissolved in a mixture of alcohol and ether,the particles that it hadtrapped fell to the bottom of the liquid and were examined ona microscope slide .Pasteurfound that in ordinary air these exists a variety of solidstructures ranging in size from0.01 mm to more than 1.0 mm .Many of these bodies resembledthe reproductive(15)s tructures of common molds, single-celled animals, and various other microbial cells .As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they couldnot be distinguished from the organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originatedthese bodies are constantly(20)being deposited on all objects.Pasteur showed that if a nutrient solution was sealed in a glass flask and heated toboiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary forspontaneous generation and that the air inside the sealed flaskwas affected in some way(25)by heating so that it would no longer support spontaneousgeneration. Pasteur constructed a swan-necked flask in which putrefying materials could he heated to boiling, but aircould reenter. The bends in the neck preventedmicroorganisms from getting in the flask.. Material sterilized insuch a flask did not putrefy.1,What does the passage mainly discuss?(a)Pasteur’ s influence on the development of the microscope.(b)The origin of the theory of spontaneous generation .(c)The effects of pasteurization on food.(d)Pasteur’ s argumentnstagaithe theory of spontaneous generation . 2,The phrase “ teeming with ” in line 2 is closest in meaning to (a)full of(b)developing into(c)resistant to(d)hurt by3,Which of the following questions did the theory of spontaneous generation attempt to answer?(a)What is the origin of the living organisms are seen on some food?(b)How many types of organisms can be found on food?(c)What is the most effective way to prepare living organisms for microscopic examination?(d)How long can food stand before it putrefies?4,The word“ resemble” in line 9 is closest in meaning to(a)benefit from(b)appear similar to(c)join together with(d)grow from5,The purpose of the“ guncotton” mentioned in paragraph 2 was to (a)trap particles for analysis (b)slow theprocess of putrefaction (c)increase the airflowto the microscopic slide (d)aid the mixing ofalcohol and ether6,The author mention “” in line 14 in describing the (a)thickness of alayer of organisms that was deposited on an object (b)diameter ofthe fibers that were in the guncotton filters (c)thickness of themicroscope slides that were used(d)size of the particles that that were collected7.The word “ postulated ” in line 19 is closest in meaning to(a)analyzed(b)doubted(c)persuaded(d)suggested8.The objects that Pasteut removed from the air in his experimentwere remarkable because they were(a)primarily single-celled organisms(b)no different from objects found in putrefyingmaterials (c)fairly rare(d)able to live in a mixture of alcohol and ether9.The word“ it” in line 22 refers to(a)a nutrient solution(b)a glass flask(c)boiling(d)spontaneous generation10.According to paragraph 3,proponents of spontaneous generation believed that which of the following was important forthe process to succeed ?(a)A sealed container(b)Fresh air(d)The presence of nutrients11.It can be inferred from paragraph 3 that Pasteur employed a swam-necked flask to(a)store sterilized liquids for use in futureexperiments (b)prevent heat from building up in asolution (c)disprove a criticism of his conclusions(d)estimate the number of organisms in a liter of airQuestions 12-20In the early decades of the United States ,the agrarian movement promoted the farmeras society ’heros. In the minds of agrarian thinkers andwriters ,the farmer was a person on whose well-being the health of the new country depended .The period between theRevolution, which ended in 1783,and the Civil War ,whichended in 1865 ,was the age of(5 )the farmer in the United States .Agrarianphilosophers ,represented most eloquently byThomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a goodsociety, their political virtue ,and their Superior morality .Andvirtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy .Consequently ,government at(10)all levels worked to encourage farmers as a social group and agriculture as economicenterprise.Both the national and state governments developed transportation infrastructure,building canals, roads, bridges, and railroads ,deepening harbors ,and removing obstructions from navigable streams .The national government imported plant and animal varieties and(15)launched exploring expeditions into prospective farmlands in the West .In addition ,government trade policies facilitated the exporting of agriculturalFor their part ,farmers seemed to meet the social expectations agrarian philosophershad for them ,as their broader horizons and greater self-respect, both products of the Revolution ,were reflected to some degree in their behavior .Farmers seemed to become(20)more scientific ,joining agricultural societies and reading the farm newspapers that sprangup throughout the country .They began using improved implements, tried new crops andpure animal breeds , and became more receptive to modern theories of soil improvement .They also responded to inducements by national and state governments .Farmersstreamed to the West ,filling frontier lands with stunningrapidity .But farmers responded(25)less to the expectations of agrarians and governmentinducements than to growing market opportunities .European demand for food from the United States seemed insatiable . War, industrialization , and urbanization all kept demand high in Europe . United States citiesand industries grew as well; even industries not directlyrelated to farming thrived becauseof the market, money ,and labor that agriculture provided .12.What does the passage mainly discuss?(a)The agrarian philosophy of Thomas Jefferson(b)The role of the national government in the development of agriculture(c)Improvements in farming techniques(d)The impact of the increased importance of the farmer13.The word “ depended ” in line 3 is closest in meaning to(a)improved(b)relied(c)demanded(d)explained14.The author mentions Thomas Jefferson in paragraph 1 as an(a)a leader during the Revolution(b)an inventor of new farming techniques(c)a philosopher who believed farmers were essential to thecreation of a good society(d)a farmer who guided the agrarian movement toward an emphasison economic development15.The phrase“ subscribed to” incloslinest8 inis meaning to(a)contributed to(b)agreed with(c)thought about(d)expanded on16.Which of the following statements is supported by the information in paragraph 1?(a)All government policy makers accepted Jefferson’views of agriculture and farmers.(b)Agricultural production declined between 1783 and 1861.(c)The majority of farmers worked for the government.(d)Agriculture was a vital part of the nation’ s economy.17.According to the passage , the national and state governmentsdid all of the following EXCEPT(a)build roads(b)import new plant varieties(c)give farmers money for their crops(d)develop policies that helped farmers export their products18.All of the following are mentioned as examples of farmers ’ meeting the expectations of agrarian philosophers EXCEPT (a)obtaining information from farm newspapers(b)accumulating personal wealth(c)planting new crops(d)becoming more scientific19.The word“ stunning” in line 24 is closest in meaning to(a)predictable(b)impressive历年托福考试阅读真题汇总包括答案```(c)famous(d)gradual20.Which of the following statements is best supported by paragraph 4?(a)Agricultural development contributed to development in other parts of the economy.(b)European agricultural products were of a higher quality than those produced in the United States.(c)The growing settlement of the West led to a decrease in agricultural production.(d)Farmers were influenced more by government policies than by market opportunities.Question 21-29The wide variety of climates in North America has helped spawn a complex pattern ofsoil regions. In general, the realm ’ s soils also reflect the broad environmental partitioninginto “ humid America ”and “ arid America. ”Where annual precipitation exceeds 20 inches(50 centimeters),soils in humid areas tend to be acidic in chemical content, Since crops(5 ) do best in soils that are neither acidic(higher in acid content) noralkaline(higher in salt content).fertilization is necessary to achieve the desired level of neutrality between the```two. Arid America ’soils are typically alkaline and must be fertilized back towardneutrality by adding acidic compounds. Although many ofthese dryland soils, particularlyin the Great Plains, are quite fertile, European settlers learned over a century ago that(10)water is the main missing ingredient in achieving their agricultural potential. In the1970’ s,certain irrigation methods were perfected and finally provided a real opportunityto expand more intensive farming west from the Central Lowland into the drier portionsof the Great Plains. Glaciation also enhanced the rich legacy of fertile soils in the centralUnited States,both from the deposition of mineral-rich glacial debris left by meltwater(15)and from thick layers of fine wind-blown glacial material, called loess, in and around themiddle Mississippi Valley.Natural vegetation patterns could be displayed on a map of North America, but theenormous human modification of the North American environment in modern times hasall but reduced this regionalization scheme to the level of the hypothetical. Nonetheless,(20)the humid America-arid America dichotomy is still a valid generalization: the naturalvegetation of areas receiving more than 20 inches of water yearly is forest, whereas thedrier climates give rise to a grassland cover. The forests of North America tent to makea broad transition by latitude. In the Canadian North, needle-leaf forests dominate, butthese coniferous trees become mixed with broadleaf deciduous trees as one crosses the(25)border into the Northeast United States. As one proceedstoward the Southeast, broadleaf vegetation becomes dominant.Arid America mostly consists of short-grass prairies orstepper. The only areas of true desert are in the Southwest.```21 What aspect of North America does the passage mainly discuss?(A)The wide variety of climates(B)Soil types and vegetation patterns(C)Improved irrigation methods and the expansion of agriculture(D)The change in precipitation patterns22 The word“ spawn” in line 1 is closest in meaning to(A)distinguish(B)eliminate(C)protect(D)create23 The word“ partitioning” in line 2 is closest in meaning to(A)division(B)modification(C)opening(D)circulating24 According to the passage, acidic soils tent to be associated with(A) a high salt content(B)an increase in farming(C)large amounts of rain(D)glacial meltwater25 The word“ enhanced” in line 13 is closest in meaning to(A)implied(B)increased(C)indicated(D)informed26 How did glacial meltdown affect the soil in North America?(A)It redistributed the soil types(B)It added salt to the soil(C)It made the soil more neutral in content(D)It added minerals to the soil27 The phrase“regionalizationthis scheme” in line 19 refers to the(A)movements of glacial deposits```(B)patterns of natural vegetation(C)human modification of the North American environment(D)distinction between humid America and arid America28 The word“ transition” in line 23 is closest in meaning to(A)elevation(B)change(C)advantage(D)condition29 The passage supports which of the following statements?(A)Arid America is not necessarily characterized by the presenceof deserts(B)Most of Canada and the northeastern United States consists ofshort-grass prairies wherever natural vegetation has not been modified by humans(C)The accumulation of loess is primarily the result of irrigation(D)Glaciation removed the fertile layer of soil from much of theMississippi ValleyQuestions 30-40Most sources of illumination generate light over an appreciable period, and indeed ifan object is lit for a very brief time(less that 1/25 second),the human eye will not reactin time to see the object. A photographic emulsion---that is, alight-sensitive coating on photographic film, paper, or glass--- will, however, record much shorter bursts of light. A(5 ) photographic flash can therefore be used to capture high-speed movement on film as wellas to correct deficiencies of the normal surrounding lighting.Photoflash is now generated electronically, but the earliest form, first used in 1864, was a paper bag containingmagnesium wire and some oxygen-rich substance, such as potassium chlorate. When thebag was ignited, the metal burned with an intense flash. A contemporary observer reported(10)that “ this quite unsafe device seems to have done nothing worse that engulf the room indense smoke and lead to pictures of dubious quality and odd poses. ”The evolution of the photoflash was slow, flashbulbs, containing fine wire made of ametal, such as magnesium or aluminum, capable of beingignited in an atmosphere of pure oxygen at low pressure, were introduced only in the 1920’arliest.Inthetype, the metal (15)was separated from the oxygen by a thin glass bulb. Theflash was fired by piercing thebulb and allowing the oxygen to come into contact with the metal, which ignitedspontaneously. Later bulbs were fired by an electric battery, which heated the wire bypassing a small current through it. Other combinations, such as the pairing of oxygendifluoride with zirconium, have also been used. In each case enough energy is given out to(20) heat the oxidizable metal momentarily to a white-hot emissionof visible light. The smoke particles are so small that they cool rapidly; but since they are white, theycontribute to the brilliance by reflecting the light from their still-glowing neighbors. A slightly bigger form of the metal will burn for a longer time.30 What does the passage mainly discuss?(A)The history of the photoflash(B)Theories about how the eye reacts to light(C)The technology of modern photography(D)The dangers of using the early photoflash31 According to the passage,1/25 second is the minimum amount of time required for the(A)recording of an image on film(B)generation of artificial light(C)creation of a photographic emulsion(D)human eye to react to light32 According to the passage, an advantage of using a photoflash is that it(A)can produce repeated bursts of light(B)intensities colors in photographs(C)is short enough not to bother human eyes(D)supplements existing lighting33 The word“ ignited” in line 9 is closestniingmeato(A)set on fire(B)cut into(C)opened(D)shaken34 Which of the following phrases is defined in paragraph 1?(A) ” appreciable period” (line 1)(B) ” photographic emulsion” (line 3)(C)” high-speed movement” (line 5)(D)” odd poses” (line 11)35 The word“ evolution” in line 12 is closest in meaning to(A)publicity(B)adoption(C)development(D)manufacture36 The function of the glass in the first flashbulbs was to(A)produce the spark that initiated the flash(B)magnify the light produced by the flash(C)protect the photographer from the heat of the flash(D)keep the metal and oxygen apart before the flash37 The word“ it” in line 18 refers to(A)oxygen(B)battery(C)wire(D)current38 The word“ momentarily” in line 20 is closest iningmeanto(A)effortlessly(B)briefly(C)electronically(D)gradually39 According to the passage, the white color of the smokeparticles generated by a flashbulb contributes to(A)rapid cooling(B)bright illumination(C)electrical conductivity(D)intense heat40 According to the passage, a flashbulb can be made to burn longer by using(A)thicker wire(B)more oxygen(C)thinner glass(D)continuous electricityQuestions 41-50The stylistic innovation in paining known as Impressionism began in the 1870’ sThe. Impressionists wanted to depict what they saw in nature, but they were inspired to portray fragmentary moments by the increasingly fast pace of modern life. Theyconcentrated onthe play of light over objects, people, and nature, breaking up seemingly solid surfaces,(5 ) stressing vivid contrast between colors in sunlight and shade, and depiction reflected lightin all of its possibilities. Unlike earlier artists, they did not want to observe the world from indoors. They abandoned the studio, painting in the open air and recording spontaneous Impressions of their subjects instead of making outside sketches and thenmoving indoorsto complete the work form memory.(10) Some of the Impressionists painting’ methods were affected by technologicaladvances. For example, the shift from the studio to the openair was made possible inpart by the advent of cheap rail travel, which permitted easy and quick access to thecountryside or seashore, as well as by newly developed chemical dyes and oils that ledto collapsible paint tubes, which enabled artists to finishtheir paintings on the spot.(15)Impressionism acquired its name not from supporters but from angry art lovers whofelt threatened by the new painting. The term “ Impressionism ” was born in 1874,whena group of artists who had been working together organizedan exhibition of theirpaintings in order to draw public attention to their work. Reaction from the public andpress was immediate, and derisive. Among the 165 paintingsexhibited was one called(20)Impression:Sunrise, by Claude Monet(1840-1926),Viewedthrough hostile eyes,Monet ’ spainting of a rising sun over a misty, watery scene seemed messy, slapdash,and an affront to good taste.

托福阅读TPO1答案解析

托福阅读答案1.dramatic剧烈的，戏剧化的，就单词本身能够想到drama戏剧，所以这个应该是戏剧的形容词，原文后句说在几十米的垂直距离内，树木完全被低矮的灌木和草取代了，所以变化非常剧烈，A渐渐B复杂C可见的都不靠谱2.以lower timberline做关键词定位至本段最后一句，说有lower timberline是因为a lack of moisture，缺乏湿度，等于A选项中的没有水3.分别以upper timberline和lower timberline为关键词定位至本段倒数两句，不管是upper timberline还是lower timberline都是快速的过渡带，树还是有的，只是在向草原等等过渡，所以A错，既然是过渡，也就是边界了，B对，C没说，只有lower timberline缺水，所以D说both错4.以deciduous trees做关键词定位至原文的第三句和第四句，根据第四句说有的地方的timberline是由落叶树构成的，所以timberline上还是有落叶树的，所以选项A和B说反，D项moisture原文没说，第三句说timberline 通常是常绿树构成的，第四句说有的时候也出现落叶树，所以常绿树比落叶树出现的概率大，所以C正确5.attain获得，想到相似的obtain和retain，原文说中高纬度的树木会变形，在山脊处怎么样更高，后半句的whereas所在句与之并列，其中reach greater heights应该和考的那部分是并列的，所以attain也是reach 之意，答案是achieve，A要求B反对抵抗D忍耐都不对6.并列句，往前找，找主语，trees是正确答案，此外，被暴露在大风之下的应该是树，山谷山脊和高度都不靠谱7.prone可能，倾向于。

原文说热带地区山谷是更有利于生长的地方因为那里怎么样干涸，比较有利生长当然不容易干涸，C和D的意思都是能干涸，所以都不对，A适应不靠谱，所以B正确8..以middle and upper latitudes做关键词定位至原文第三四两句，说中高纬度地区树木在很大程度上受到积雪覆盖的时长和深度的影响，山谷地区积雪深，时间长，所以树长得不好，所以是negatively affected，选项B 和C与原文相反，D违反常识9.原句说风速增加而且会给树木很大压力，已经被blablabla证实。

▉托福TPO1阅读Passage1原文文本： Timberline Vegetation on Mountains 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. 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 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 cannotmature 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. ▉托福TPO1阅读Passage1题目：第1题：The word"dramatic"in the passage is closest in meaning to A.Gradual plex C.Visible D.Striking Paragraph 1 is marked with 第2题：Where is the lower timberline mentioned in paragraph 1 likely to be found?

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

According to the passage, fairs in Philadelphia were held(A) on the same day as market says (B) as often as possible(C) a couple of times a year (D) whenever the government allowed it7. It can be inferred that the author mentions "Linens and stockings" in line 12 to show that they were items that(A) retail merchants were not willing to sell(B) were not available in the stores in Philadelphia(C) were more popular in Germantown man in Philadelphia(D) could easily be transported8. The word "eradicate" in line 16 is closest in meaning to(A) eliminate (B) exploit (C) organize (D) operate9. What does the author mean by stating in line 17 that "economic development was on the merchants' side "?(A) Merchants had a strong impact on economic expansion.(B) Economic forces allowed merchants to prosper.(C) Merchants had to work together to achieve economic independence(D) Specialty shops near large markets were more likely to be economically successful.10. The word "undergoing" in line 22 is closest in meaning to(A) requesting (B) experiencing (C) repeating (D) includingQuestions 11-22Avicolturists, people who raise birds for commercial sale, have not yet learned how to simulate the natural incubation of parrot eggs in the wild. They continue to look for better ways to increase egg production and to improve chick survival rates.When parrots incubate their eggs in the wild, the temperature and humidity of the nest are controlled naturally. Heat is transferred from the bird's skin to the top portion of the eggshell, leaving the sides and bottom of the egg at a cooler temperature. This temperature gradient may be vital to successful hatching. Nest construction can contribute to this temperature gradient Nests of loosely arranged sticks, rocks, or dirt are cooler in temperature at the bottom where the egg contacts the nesting material.Such nests also act as humidity regulators by allowing rain to drain into the bottom sections of the nest so that the eggs are not in direct contact with the water. As the water that collects in the bottom of the nest evaporates, the water vapor rises and is heated by the incubating bird, which adds significant humidity to the incubation environmentIn artificial incubation programs, aviculturists remove eggs from the nests of parrots and incubate them under laboratory conditions. Most commercial incubators heat the eggs fairly evenly from top to bottom, thus ignoring the bird's method of natural incubation, and perhaps reducing the viability and survivability of the hatching chicks.When incubators are not used, aviculturists sometimes suspend wooden boxes outdoors to use as nests in which to place eggs. In areas where weather can become cold after eggs are laid, it is very important to maintain a deep foundation of nesting material to act as insulator against the cold bottom of the box. If eggs rest against the wooden bottom in extremely cold weather conditions, they can become chilled to a point where the embryo can no longer survive. Similarly, these boxes should be protected from direct sunlight to avoid high temperatures that are also fatal to the growing embryo.Nesting material should be added in sufficient amounts to avoid both extreme temperature situations mentioned above and assure that the eggs have a soft, secure place to rest.11. What is the main idea of the passage?(A) Nesting material varies according to the parrots' environment.(B) Humidity is an important factor in incubating parrots' eggs.(C) Aviculturists have constructed the ideal nest box for parrots.(D) Wild parrots' nests provide information useful for artificial incubation.12. The word "They" in line 2 refers to(A) aviculturists (B)birds (C)eggs (D) rates13. According to paragraph 2, when the temperature of the sides and bottom of the egg are cooler than the top, then(A) there may be a good chance for successful incubation(B) the embryo will not develop normally(C) the incubating parent moves the egg to a new position.(D) the incubation process is slowed down14. According to paragraph 2, sticks, rocks, or dirt are used to(A) soften the bottom of the nest for the newly hatched chick(B) hold the nest together(C) help lower the temperature at the bottom of the nest(D) make the nest bigger15. According to paragraph 2, the construction of the nest allows water to(A) provide a beneficial source of humidity in the nest(B) loosen the materials at the bottom of the nest(C) keep the nest in a clean condition(D) touch the bottom of the eggs16. All of the following are part of a parrot's incubation method EXCEPT(A) heating the water vapor as it rises from the bottom of the nest(B) arranging nesting material at the bottom of the nest(C) transferring heat from the parent to the top of the eggshell(D) maintaining a constant temperature on the eggshell17. The word "suspend" in line 19 is closest in meaning to(A) build (B) paint (C)hang (D) move18. The word "fatal" in line 25 is closest in meaning to(A) close (B) deadly (C) natural (D) hot19. The word "secure" in line 27 is closest in meaning to(A) fiesh (B)diy (C)safe (D)warm20. According to paragraph 3, a deep foundation of nesting material provides(A) a constant source of humidity (B) a strong nest box(C) more room for newly hatched chicks (D) protection against cold weather21. Which of the following is a problem with commercial incubators?(A) They lack the natural temperature changes of the outdoors.(B) They are unable to heat the eggs evenly(C) They do not transfer heat to the egg in the same way the parent bird does.(D) They are expensive to operate.22. Which of the following terms is defined in the passage?(A) Aviculturists (line I) (B) Gradient (line 8)(C) Incubation (line 15) (D) Embryo (line 24)Questions 23-33The mineral particles found in soil range in size from microscopic clay particles to large boulders. The most abundant particles—sand, silt, and clay—are the focus of examination in studies of soil texture. Texture is the term used to describe the composite sizes of particles in a soil sample, typically several representative handfuls.To measure soil texture, the sand, silt, and clay particles are sorted out by size and weight. The weights of each size are then expressed as a percentage of the sample weight.In the field, soil texture can be estimated by extracting a handful of sod and squeezing the damp soil into three basic shapes; (1) cast, a lump formed by squeezing a sample in a clenched fist; (2) thread, a pencil shape formed by rolling soil between the palms; and (3) ribbon, a flatfish shape formed by squeezing a small sample between the thumb and index finger. The behavioral characteristics of the soil when molded into each of these shapes, if they can be formed at all, provides the basis for a general textural classification. The behavior of the soil in the hand test is determined by the amount of clay in the sample. Clay particles are highly cohesive, and when dampened, behave as a plastic. Therefore the higher the clay content in a sample, the more refined and durable the shapes into which it can be molded.Another method of determining soil texture involves the use of devices called sediment sieves, screens built with a specified mesh size. When the soil is filtered through a group of sieves, each with a different mesh size, the particles become grouped in corresponding size categories. Each category can be weighed to make a textural determination. Although sieves work well for silt, sand, and larger particles, they are not appropriate for clay particles. Clay is far too small to sieve accurately; therefore, in soils with a high proportion of clay, the fine particles are measured on the basis of their settling velocity when suspended in water .Since clays settle so slowly, they are easily segregated from sand and silt. The water can be drawn off andevaporated, leaving a residue of clay, which can be weighed.23. What does the passage mainly discuss?(A) Characteristics of high quality soil(B) Particles typically found in most soils(C) How a high clay content affects the texture of soil(D) Ways to determine the texture of soil24. The author mentions "several representative handrals" in line 4 in order to show(A) the range of soil samples(B) the process by which soil is weighed(C) the requirements for an adequate soil sample(D) how small soil particles are25. The phrase "sorted out" in line 5 is closest in meaning to(A) mixed (B) replaced (C) carried (D) separated26. It can be inferred mat the names of the three basic shapes mentioned in paragraph 2 reflect(A) the way the soil is extracted (B) the results of squeezing the soil(C) the need to check more than one handful (D) the difficulty of forming different shapes27. The word "dampened" in line 15 is closest in meaning to(A) damaged (B) stretched (C) moistened (D) examined28. Which of the following can be inferred from the passage about a soil sample with little or no clay in it?(A) It is not very heavy. (B) It may not hold its shape when molded.(C) Its shape is durable (D) Its texture cannot be classified29. The word "they" in line 23 refers to(A) categories (B) sieves (C) larger particles (D) clay particles30.

During the procedure described in paragraph 3, when clay particles are placed into water they(A) stick to the sides of the water container (B) take some time to sink to the bottom(C) separate into different sizes (D) dissolve quickly32. The word "fine" in line 24 is closest in meaning to(A) tiny (B) many (C) excellent (D) various33. All of the following words are defined in the passage EXCEPT(A) texture (line 3) (B) ribbon (line 11) (C) sediment sieves (line 19) (D) evaporated (line 27)Questions 34-43A number of factors related to the voice reveal the personality of the speaker. The first is the broad area of communication, which includes imparting information by use of language, communicating with a group or an individual and specialized line communication through performance. A person conveys thoughts and ideas through choice of words, by a tone of voice that is pleasant or unpleasant, gentle or harsh, by the rhythm that is inherent within the language itself, and by speech rhythms that are flowing and regular or uneven and hesitant, and finally, by the pitch and melody of the utterance. When speaking before a group, a person's tone may indicate unsureness or fright, confidence or calm. At interpersonal levels, the tone may reflect ideas and feelings over and above the words chosen, or may belie them. Here the conversant's tone can consciously or unconsciously reflect intuitive sympathy or antipathy, lack of concern or interest, fatigue, anxiety, enthusiasm or excitement, all of which are .usually discernible by the acute listener. Public performance is a manner of communication that is highly specialized with its own techniques for obtaining effects by voice and /or gesture. The motivation derived from the text, and in the case of singing, the music, in combination with the performer's skills, personality, and ability to create empathy will determine the success of artistic, political, or pedagogic communication.Second, the voice gives psychological clues to a person's self-image, perception of others, and emotional health. Self-image can be indicated by a tone of voice that is confident, pretentious, shy, aggressive, outgoing, or exuberant, to name only a few personality traits. Also the sound may give a clue to the facade or mask of that person, for example, a shy person hiding behind an overconfident front. How a speaker perceives the listener's receptiveness, interest, or sympathyin any given conversation can drastically alter the tone of presentation, by encouraging or discouraging the speaker. Emotional health is evidenced in the voice by free and melodic soundsof the happy, by constricted and harsh sound of the angry, and by dull and lethargic qualities of the depressed34. What does the passage mainly discuss?(A) The function of the voice in performance (B) The connection between voice and personality(C) Communication styles (D) The production of speech35. What does the author mean by staring that, "At interpersonal levels, tone may reflect ideas and feelings over and above the words chosen" (lines 9-10)?(A) Feelings are expressed with different words than ideas are.(B) The tone of voice can cany information beyond the meaning of words.(C) A high tone of voice reflects an emotional communication.(D) Feelings are more difficult to express than ideas.36. The word "Here" in line 10 refers to(A) interpersonal interactions (B) the tone (C) ideas and feelings (D) words chosen37. The word "derived" in line 15 is closest in meaning to(A) discussed (B) prepared (C) registered (D) obtained38. Why does the author mention "artistic, political, or pedagogic communication" in line 17?(A) As examples of public performance (B) As examples of basic styles of communication(C) To contrast them to singing (D) To introduce the idea of self-image39. According to the passage, an exuberant tone of voice, may be an indication of a person's(A) general physical health (B) personality (C) ability to communicate (D) vocal quality40. According to the passage, an overconfident front may hide(A) hostility (B) shyness (C) friendliness (D) strength41. The word "drastically" in line 24 is closest in meaning to(A) frequently (B) exactly (C) severely (D) easily42. The word "evidenced" in line 25 is closest in meaning to(A) questioned (B) repeated (C) indicated (D) exaggerated43. According to the passage, what does a constricted and harsh voice indicate?(A) Lethargy (B) Depression (C) Boredom (D) AngerQuestions 44-50As the twentieth century began, the importance of formal education in the United States increased. The frontier had mostly disappeared and by 1910 most Americans lived in towns and cities. Industrialization and the bureaucratization of economic line life combined with a new emphasis upon credentials and expertise to make schooling increasingly important for economic and social mobility. Increasingly, too, schools were viewed as the most important means of integrating immigrants into American society.The arrival of a great wave of southern and eastern European immigrants at the turn of the century and contributed to an enormous expansion of formal schooling. By 1920 schooling to age fourteen or beyond was compulsory in most states, and the school year was greatly lengthened. Kindergartens, vacation schools, extracurricular activities, and vocational education and counseling extended the influence of public schools over the lives of students, many of whom in the larger industrial cities were the children of immigrants. Classes for adult immigrants were sponsored by public schools, corporations, unions, churches, settlement houses, and other agencies.Reformers early in the twentieth century suggested that education programs should suit the needs of specific populations. Immigrant women were one such population.Schools tried to educate young women so they could occupy productive places in the urban industrial economy, and one place many educators considered appropriate for women was the home.Although looking after the house and family was familiar to immigrant women, American education gave homemaking a new definition. In preindustrial economies, homemaking had meant the production as well as the consumption of goods, and it commonly included income-producing activities both inside and outside the home, in the highly industrialized early-twentieth-century United States, however, overproduction rather than scarcity was becoming a problem. Thus, the ideal American homemaker was viewed as a consumer rather than a producer. Schools trained women to be consumer homemakers cooking, shopping, decorating, and caring for children "efficiently" in their own homes, or if economic necessitydemanded, as employees in the homes of others. Subsequent reforms have made these notions seem quite out-of-date.44. It can be inferred from paragraph 1 that one important factor in the increasing importance of education in the United States was(A) the growing number of schools in frontier communities(B) an increase in the number of trained teachers(C) the expanding economic problems of schools(D) the increased urbanization of the entire country45. The word "means" in line 6 is closest in meaning to(A) advantages (B) probability (C) method (D) qualifications46. The phrase "coincided with" in line 9 is closest in meaning to(A) was influenced by (B) happened at the same time as(C) began to grow rapidly (D) ensured the success of47. According to the passage, one important change in United States education by the 1920's was that(A) most places required children to attend school(B) the amount of time spent on formal education was limited(C) new regulations were imposed on nontraditional education(D) adults and children studied in the same classes48. Vacation schools and extracurricular activities are mentioned in lines 11-12 to illustrate(A) alternatives to formal education provided by public schools(B) the importance of educational changes(C) activities that competed to attract new immigrants to their programs.(D) the increased impact of public schools on students.49. According to the passage, early-twentieth century education reformers believed that(A) different groups needed different kinds of education(B) special programs should be set up in frontier communities to modernize them(C) corporations and other organizations damaged educational progress(D) more women should be involved in education and industry50. The word "it" in line 24 refers to(A) consumption (B) production (C) homemaking (D) education。

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

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 become possible because a new household convenience, the icebox, a precursor of the modern refrigerator, had been invented.Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that 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 nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm abouttwenty 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 the rapidly melting stuff in the tubs of his competitors 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.
