托福阅读长难句[答案]Which of the following best expresses the essential information in the highlighted sentence? Incorrect answer choices change the meaning in important ways or leave out essential information.1.○Functional applied-art objects cannot vary much from the basic patterns determined by the laws of physics.○The function of applied-art objects is determined by basic patterns in the laws of physics.○Since functional applied-art objects vary only within certain limits, arbitrary decisions cannot have determined their general form.○The general form of applied-art objects is limited by some arbitrary decision that is not determined by the laws of physics.2.The structure of the backbone shows, however, that Ambulocetus swam likemodern whales [by moving the rear portion of its body up and down], even though a fluke was missing.○Even though Ambulocetus swam by moving its body up and down, it did not have a backbone.○The backbone of Ambulocetus, which allowed it to swim, provides evidence of its missing fluke.○Although Ambulocetus had no fluke, its backbone structure shows that it swam like modern whales.○By moving the rear parts of their bodies up and down, modern whales swim in a different way from the wayAmbulocetus swam.3.○Desertification is a significant problem because it is so hard to reverse and affects large areas of land and great numbers of people.○Slowing down the process of desertification is difficult because of population growth that has spread over large areas of land.○The spread of deserts is considered a very serious problem that can be solved only if large numbers of people in various countries are involved in the effort.○Desertification is extre mely hard to reverse unless the population is reduced in the vast areas affected.4.○Edison was more interested in developing a variety of machines than in developing a technology based on only one.○Edison

托福长难句100句(一)
句子1In a countercurrent exchange system,the blood vessels carrying cooled blood from the flippers run close enough to the blood vessels carrying warm blood from the body to pick up some heat from the warmer blood vessels;thus,the heat is transferred from the outgoing to the ingoing vessels before it reaches the flipper itself.【难点解析】本句的难点在于复杂的后置定语干扰了阅读，给我们理解句子带来了影响。
在这个句子中就是现在分词短语carrying cooled blood…做了后置定语，造成了主语the blood vessels 和谓语run被分割，后面接着出现了另一个the blood vessels carrying warm blood……，进一步加大了理解难度，让我们一时无法理清句子结构。
找到这种后置定语，划分句子主干的时候直接忽视这种修饰性成分，句子的主要信息就变得非常清晰：In a countercurrent exchange system,the blood vessels carrying cooled blood from the flippers[定语]run close enough to the blood vessels carrying warm blood from the body[定语]to pick up some heat from the warmer blood vessels;thus,the heat is transferred from the outgoing to the ingoing vessels before it reaches the flipper itself.完成了句子主干划分之后，根据汉语的表述顺序，将后置定语往前放，这样整个句子的意思就出来了。

The expansion of desert-like 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.P2：Cause-1 erosion-windDesertification is accomplished primarily through the loss of stabilizing naturalIn other cases, the finer particles may be removed, while the sand-sized particles are accumulated to form mobile hills or ridges of sand.P3：Cause-1 erosion-watertiniest 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.P4：Cause-2 climate-global warmingIn some regions, the increase in desert areas is occurring largely as the result of a trend toward drier climatic conditions. Continued gradual global warming hasP5：Cause-3 peopleThere 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 areP6：Cause-3 people- overcultivationFour 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 failuresP7：Cause-3 people- overgrazingThe 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 of livestock grazing in an area are the reduction of the vegetation cover and the trampling and pulverization of the soil(9-D). This is usually followed by the drying of the soil and accelerated erosion.P8：Cause-3 people- firewood gatheringFirewood 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.P9：Cause-3 people- overirrigationThe final major human cause of desertification is soil salinization resulting from overirrigation. Excess water from irrigation sinks down into the water table. If noP10：conclusionThe 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(占据) approximately(大约)a fourth of the Earth's land surface, have in recent decades been increasing at an alarming pace(以惊人的速度). The expansion of desert-like conditions into areas where theydid not previously(以前) exist is called desertification(沙漠化). It has been that an additional one-fourth of the Earth's land surface is1. The word “threatened 威胁” in the passage is closest in meaning to 词汇题○ restricted 限制○ endangered danger 危险enlarge○ prevented 阻止○ rejected 拒绝Paragraph 3: Even in the areas that retain a soil cover, the reduction of vegetation(植被) typically(作为特色地) results in the loss of the soil's ability to absorb substantial(大量的) quantities of water. The impact(影响，效果) of raindrops on the loose soil tends to transfer fine clay particles(颗粒) into the tiniest soil spaces, sealing(密封) them and producing a surface that allows very little water penetration(渗透). Water absorption(吸收) is greatly reduced; consequently(因此，结果) runoff is increased, resulting in accelerated erosion(侵蚀) rates. The gradual drying of the soil caused by its diminished(减弱的) ability to absorb water results in the further loss of vegetation, so that a cycle of progressive surface deterioration(恶化) is established.2. According to paragraph 3, the loss of natural vegetation has which of the following consequences for soil? 细节题○ Increased stony content○ Reduced water absorption○ Increased numbers of spaces in the soil○ Reduced water runoffParagraph 5: There is little doubt, however, that desertification in most areas results primarily(主要地) from human activities rather thansemiarid(半干旱的) lands bordering the deserts exist in aecological balance and are limited in their potential toenvironmental 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 (超过) its diminished capacity, and desertification results.3. The word “delicate” in the passage is closest in meaning to 词汇题○ fragile○ predictable○ complex○ valuable4. According to paragraph 5, in dry periods, border areas have difficulty 细节题○ adjusting to stresses created by settlement○ retaining their fertility after desertification○ providing water for irrigating crops○ attracting populations in search of food and fuelParagraph 6: 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 natural vegetation,crop failures) of a plant cover and susceptible(易受影响的) to wind and water erosion.5. The word “progressively” in the passage is closest in meaning to 词汇题○ openly○ impressively○ objectively○ increasingly6.According to paragraph 6, which of the following is often associated with raising crops?细节题○ Lack of proper irrigation techniques○ Failure to plant crops suited to the particular area○ Removal of the original vegetation○ Excessive use of dried animal waste7. The phrase “devoid of” in the passage is closest in meaning to 词汇题○ consisting of○ hidden by○ except for○ lacking inParagraph 9: The final major human cause of desertification is soil salinization(盐碱化) 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 (蒸发) and the salts are left behind, creating a white crustal layer that prevents air and water from reaching the underlying soil.8. According to paragraph 9, the ground’s absorption of excess wate r is a factor in desertification because it can 细节题○ interfere with the irrigation of land○ limit the evaporation of water○ require more absorption of air by the soil○ bring salts to the surface9.All of the following are mentioned in the passage as contributing to desertification EXCEPT选非题○ soil erosion○ global warming○ insufficient irrigation○ the raising of livestockParagraph 10: 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(千年) will enable new soil to form. In areas where considerable soil still remains, though, a rigorously(严格地) enforced program of land protection and cover-crop planting may make it possible to reverse the present deterioration of the surface.10. 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. 句子简化题○ Desertification is a significant problem because it is so hard to reverse and affects large areas of land and great numbers of people.○ Slowing down the process of desertification is difficult because of population growth that has spread over large areas of land.○ The spread of deserts is considered a very serious problem that can be solved only if large numbers of people in various countries are involved in the effort.○ Desertification is extremely hard to reverse unless the population is reduced in the vast areas affected.11. It can be inferred from the passage that the author most likely believes which of the following about the future of desertification? 推断题○ Governments will act quickly to control further desertification.○ The factors influencing desertification occur in cycles and will change in the future. ○ Desertification will continue to increase.○ Desertification will soon occur in all areas of the world.Paragraph 7: ■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 of livestock 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. ■12. Look at the four squares [■] that indicate where the following sentence can be added to the passage.This economic reliance on livestock in certain regions makes large tracts of land susceptible to overgrazing.Where would the sentence best fit? 句子插入题13.Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage.

1. Even the kind of stability defined as simple lack of change is not always associated with maximum diversity.2. Even if the new population is of a different species, it can approximately fill the niche vacated by the extinct population and keep the food web intact.3. Their seed heads raised just high enough above the ground to catch the wind, the plants are no bigger than they need be, their stems are hollow, and all the rigidity comes from their water content.4. By contrast, in the United States an estimated 97 million birds are killed each year when they collide with buildings made of plate glass, 57 million are killed on highways each year; at least 3.8 million die annually from pollution and poisoning; and millions of birds are electrocuted each year by transmission and distribution lines carrying power produced by nuclear and coal power plants.5. 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."6. Scientists first identified this impact in 1980 from the worldwide layer of sediment deposited from the dust cloud that enveloped the planet after the impact.7. Only a few organisms especially tolerant of very salty conditions remained.8. Paleontologists have argued for a long time that the demise of the dinosaurs was caused by climatic alterations associated with slow changes in the positions of continents and seas resulting from plate tectonics.9. The answer may be that virtually all the water on Mars is now locked in the permafrost layer under the surface, with more contained in the planet’s polar caps.10. But belief in this ice-free corridor began to crumble when paleoecologist Glen MacDonald demonstrated that some of the most important radiocarbon dates used to support the existence of an ice-free corridor were incorrect.11. Spores light enough to float on the breezes were carried thousands of miles from more ancient lands and deposited at random across the bare mountain flanks.12. Interestingly enough, several of these hydrodynamic adaptations resemble features designed to improve the aerodynamics of high-speed aircraft.13.

Perceiving an apparent connection between certain actions performed by the group and the result it desires, the group repeats, refines and formalizes those actions into fixed ceremonies, or rituals.15. One, set forth by Aristotle in the fourth century B.C., sees humans as naturally imitative—as taking pleasure in imitating persons, things, and actions and in seeing such imitations.16. A more complicated system is, in general, more likely than a simple system to break down.17.

A third likely explanation for infantile amnesia involves incompatibilities between the ways in which infants encode information and the ways in which older children and adults retrieve it.21. Whether people can remember an event depends critically on the fit between the way in which they earlier encoded the information and the way in which they later attempt to retrieve it.22. Critics also point out that the shallow seaways had retreated from and advanced on the continents numerous times during the Mesozoic, so why did the dinosaurs survive the climatic changes associated with the earlier fluctuations but not with this one?23.

【托福阅读】精选阅读真题长难句50句1、 Later experiments in which researchers played recordings of songs to youngbirds showed just how precise this influence was, many of them would learnthe exact pattern of the recording they had heard.2、 The crude song of a bird reared in isolation gives some clues as to what thisrough idea may be the length, the frequency range and the breaking up intonotes are all aspects of chaffinch song shared between normal birds andthose reared in isolation.3、 Whatever the nature of the learning rules in a particular species, there is nodoubt that they are effective, it is very unusual to hear a wild bird singing asong which is not typical of its own species despite the many different songswhich often occur in a small patch of woodland.4、 Chemical analysis of bones enables archaeologists to determine theproportion of meat to vegetable foods in the diet by measuring the proportionof calcium to strontium in ancient bone because strontium in place of calciumin bones comes primarily from ingested plants.5、 Each dwelling had a different arrangement of the giant bones, which camefrom the skeletons of long-dead animals retrieved from the surrounding areaby occupants of the site, not from animals they had recently hunted.6、 In a precedent-setting decision, the Federal Energy Regulatory Commissionordered the dam removed after concluding that the environmental andeconomic benefits of a free-flowing river outweighed the electricity generatedby the dam.7、 Built nearly a century ago to provide power to lumber and paper mills in thetown of Port Angeles, these dams blocked access to upstream spawning bedsfor six species of salmon on what once was one of the most productivesalmon rivers in the world.8、 The Hetch Hetchy Dam in Yosemite National Park might be taken down toreveal what John Muir, the founder of the prestigious environmentalorganization Sierra Club, called a valley “just as beautiful and worthy ofpreservation as the maj estic Yosemite.”9、 A chance collision between two comets, or the gravitational influence of oneof the Jovian planets—Jupiter, Saturn, Uranus, and Neptune—mayoccasionally alter the orbit of a comet in these regions enough to send it tothe inner solar system and into our view.10、 These comets appear to be distributed in all directions from the Sun, forminga spherical shell around the solar system, called the Oort cloud, after theDutch astronomer Jan Oort.11、 After the arrival of hunter-gatherers in the southwestern region of NorthAmerica, several alternative types of agriculture emerged, all involvingdifferent solutions to the Southwest’s fundamental problem: how to obtainenough water to grow crops in an environment in which rainfall is so low andunpredictable that little or no farming is practiced there today.12、 That fate actually befell the Mimbres, who started by farming the floodplainand then began to farm adjacent land above the floodplain as their population ca me to exceed the floodplain’s capacity to support it.13、 However, when drought conditions returned, that gamble left them with apopulation double what the floodplain could support, and Mimbres societycollapsed suddenly under the stress.14、 One more strategy was to plant crops at many sites even though rainfall waslocally unpredictable and then to harvest crops at whichever sites did getenough rain to produce a good harvest and to redistribute some of theharvest to the people still living at all the sites that did not happen to receiveenough rain that year.15、 Sanitation problems caused by larger, more sedentary populations wouldhave helped transmit diseases in human waste, as would the use of animaldung for fertilizer.16、 The increase in many of these came not only from the fact that fewer peoplewere dying from infectious disease and were living longer but also from theresults of modern lifestyles in developed countries and among the upperclasses of developing countries – a more sedentary life leading to lessphysical activity, more stress; environmental pollution, andhigh-fat diets.17、 This evolution may have been encouraged by what some authorities considerour overuse of antibiotics, giving microorganisms a greater chance to evolveresistance by exposing them to a constant barrage of selective challenges.18、 Therefore, on many reefs it is the fast-growing, branching corals thatultimately dominate at the upper, shallower portion of the reef, whereasmore massive forms dominate in deeper areas.19、 The fact that almost all small invertebrates on reefs are so well hidden orhighly camouflaged is another indicator of how prevalent predation is onreefs and its importance in determining reef structure.20、 Finally, they need reliable methods of storage because, where plant foodscannot provide a dietary safety net, planning has to be precise and detailedto ensure that there is enough to tide them over in periods of shortage.21、 Coins also provide a valuable source of written records: they can revealinformation about the location where they are found, which can provideevidence about trade practices there, and their inscriptions can beinformative about the issuing authority, whether they werecity-states (as inancient Greece) or sole rulers (as in Imperial Rome or in the kingdoms ofmedieval Europe).22、 The great risk with historical records is that they can impose their ownperspective so that they begin not only to supply the answers to ourquestions but subtly to determine the nature of those questions and even ourconcepts and terminology.23、 Not all botanists agree with an African-South American center for theevolution and dispersal of the angiosperms, pointing out that many of themost primitive forms of flowering plants are found in the South Pacific,including portions of Fiji, New Caledonia, New Guinea, eastern Australia, andthe Malay Archipelago.24、 To elaborate, before the eighth century, the elite marriage practice, whichwas an important instrument of political alliance making, had encouragedrulers to maintain multiple palaces: that of their own family and those of theirspouses, who commonly remained at or near their native family headquarters,at least for some years after marriage.25、 Nearly five billion years ago, some external influence, such asa shock wavetraveling from a catastrophic explosion (supernova), may have triggered thecollapse of this huge cloud of gases and minute grains of heavier elements,causing the cloud to begin to slowly contract due to the gravitationalinteractions among its particles.26、 Nearly five billion years ago, some external influence, such asa shock wavetraveling from a catastrophic explosion (supernova), may have triggered thecollapse of this huge cloud of gases and minute grains of heavier elements,causing the cloud to begin to slowly contract due to the gravitationalinteractions among its particles.27、 Steady overseas demand for colonial products created a prosperity thatenabled colonists to consume ever-larger amounts not only of clothing but ofdishware, home furnishings, tea, and a range of other items both produced inBritain and imported by British and colonial merchants from elsewhere.28、 Such materials as iron and nickel and the elements of which the rock-formingminerals are composed—silicon, calcium, sodium, and so forth—formedmetallic and rocky clumps that orbited the Sun.29、 This act was intended less to raise revenue than to serve as a protective tariff(tax) that would benefit British West Indian sugar producers at the expenseof their French rivals.30、 Parliament used British tax money to pay modest incentives to Americansproducing such items as silk, iron, dyes, hemp, and lumber, which Britainwould otherwise have had to import from other countries, and it raised theprice of commercial rivals’ imports by imposing protective tariffs on them.31、 The concept of chromatic adaptation was proposed in 1883; and thehypothesis was accepted for about 100 years, until it was realized that suchzonation did not necessarily occur and that the distribution of seaweedsdepended more on herbivory (the consumption of plant material),competition, varying concentration of the specialized pigments, and the abilityof seaweeds to alter their forms of growth.32、First, demand for news increased as Europe’s commercial and politicalinterests spread around the globe—merchants in London, Liverpool, orGlasgow, for example, came to depend on early news of Caribbean harvestsand gains and losses in colonial wars.33、 Industries with high concentrations of employment in urban areas, where aworker’s change of employer does not necessarily require investing in achange of residence, appear to have higher rates of job turnover thanindustries concentrated in nonmetropolitan areas do.34、 Some researchers, for example, have argued that a particular kind of pottery,called Ramey incised (which is incised with figures of eyes, fish, arrows, andabstract objects and was used by the people in the area of present-dayMissouri and Illinois at about A.D 900), was primarily used to distribute foodbut was also used to communicate the idea that the society’s elite, for whomthe pots were made, were mediators of cosmic forces.35、 There are several limiting factors, but results from a recent experimentsuggest that in areas of the ocean where other nutrients are plentiful, ironmay be one of the most important and, until recently, unrecognized variablescontrolling phytoplankton production.36、 In 1894, C. Lloyd Morgan, an early comparative behaviorist, insisted thatanimal behavior be explained as simply as possible without reference toemotions or motivations since these could not be observed or measured.37、 Assuming that in the early 1770s at least half of the demand for grain fromfarmers with surpluses was satisfied through long-distance channels, theproportion of grain produced for consumption beyond the local marketprobably accounted for about a quarter of total grain production consumedby humans.38、Sea turtles’ eggs are laid at night to minimize the likelihood of their discoveryby predators, and the offspring, when ready to emerge from their eggshellsand dig their way out of the sand, hatch at night for the same reason.39、 In short, therefore, the site Memphis offered the rulers of the Early DynasticPeriod an ideal location for controlling internal trade within their realm, anessential requirement for a state-directed economy that depended on themovement of goods.40、 In particular, research has focused on determining why such an apparentlyinhospitable place as Chaco, which today is extremely arid and has very shortgrowing seasons, should have favored the concentration of labor that musthave been required for such massive construction projects over brief periodsof time.41、 In one case, seeds of the arctic lupine, a member of the pea family recoveredfrom ancient lemming burrows in the Arctic, germinated in three days eventhough they were carbon-dated at more than 10,000years old!42、 In fact, unpredictability is probably a greater problem than is the severity ofthe unfavorable period.43、 Similar reasoning suggested that one could estimate total elapsed geologictime by dividing the average thickness of sediment transported annually tothe oceans into the total thickness of sedimentary rock that had ever beendeposited in the past.44、 The process that marine creatures use to create light is like that of thecommon firefly and similar to that which creates the luminous green colorseen in plastic glow sticks, often used as children’s toys or for illuminationduring nighttime events.45、 But its appearance under a microscope is even more spectacular, the livingcopepod appears as if constructed of delicately handcrafted, multicoloredpieces of stained glass.46、 Cleared lands would more likely have been worked by hand tilling, with littledirect help from animals, and the vast forests natural to Northern Europeremained either untouched, or perhaps cleared in small sections by fire, andthe land probably used only so long as the ash-enriched soil yielded goodcrops and then abandoned for some other similarly cleared field.47、 Because nests at the edges of breeding colonies are more vulnerable topredators than those in the centers, the preference for advantageous centralsites promotes dense centralized packing of nests.48、 In discussing the growth of cities in the United States in the nineteenthcentury, one cannot really use the term “urban planning,” as it suggestsmodern concerns for spatial and service organization which, in most instances,did not exist before the planning revolution called the City BeautifulMovement that began in the 1890s.49、 There the limits that topography imposed on production have been tightenedby climate, with the result that agricultural output has been more modest andless reliable, making the risk of crop failure and hardship commensuratelygreater.50、 Because liquid water was present, self-replicating molecules of carbon,hydrogen, and oxygen developed life early in Earth’s history and haveradically modified its surface, blanketing huge parts of the continents withgreenery.。

From north or south in the Yucatan Peninsula, where the Maya lived, rainfall ranges from 18 to 100 inches (457 to 2, 540 millimeters) per year, and the soils become thicker, so that the southern peninsular was agriculturally more productively and supported denser populations.

托福阅读长难句精选为了让大家更好的准备托福考试，给大家整理托福阅读长难句，下面就和大家分享，来欣赏一下吧。
托福阅读长难句1一般情况下，句子主语、宾语和句子中其他部分的名词可能因包含大量前置或后置定语成分而变得非常复杂，而整句的谓语动词，其前后最多有副词作修饰，所以相对容易判断。
我们一旦找到整句谓语动词，它的施动者-主语、受动者-谓语以及主干也自然容易进一步识别。
例句1：A desire to throw over reality a lightthat never was might give away abruptly to the desire on the part of what wemight consider a novelist-scientistto record exactly and concretely thestructure and texture of a flower.这个句子里出现的动词有throw, was, might give, mightconsider和record等。
首先，动词不定式不能作谓语，去掉throw和record;was 后不能紧跟情态动词，所以was和might give应属不同的句子，往前看我们发现that never was形成S+V格式，且紧跟着名词light后，再根据句意判断可知that never was 为a light的后置定语从句;稍作判断可知to throw over reality a light 为不定式做A desire的后置定语，此时吧它的不定式后置定语及alight的后置定语拿掉可得到简化结构：A desire might give awayabruptly to thedesire…。
Abruptly显然修饰动词短语give away。
至此我们得到a desire(S)+might giveaway(V)+thedesire(O), 经过这样的简化，整句主干已经得到;至于might consider, 明显和它前面的we组成S+V格式，这个从句跟在on the part of 后面做整句宾语thedesire的后置定语从句纵观整句，主语谓语后都跟了较长的定语成分，造成我们判断它们终结位置的困难。
而动词的修饰成分一般较短，由它们入手更容易理清句子的各个部分。
例句2：(提示：作语法分析前请排除生词)Thus, what in contrast to the Puritancolonies appears to Davis to be peculiarly Southern- acquisitiveness, a stronginterest in politics and the law,and a tendency to cultivate metropolitancultural models- was not only moretypically English than the cultural patternsexhibited by Puritan Massachusettsand Connecticut, but also almost certainlycharacteristic of most other earlymodern British colonies from Barbados northto Rhode Island and New Hampshire.这个句子较长，但从动词入手可我们迅速提取到主干。
首先忽略不定式(tobe , to cultivate)，这个句子里出现的动词仅有appears,was, exhibited;appears前的in contrast to the Puritancolonies是较易识别的比较状语，所以这部分可以还原成whatappears to be peculiarly Southern to Davis incontrast to the Puritan colonies,这样what appears 形成S+V结构;was not only ...butalso可以看成是系表结构，其中两组表语并列;exhibited 后面有介词by，而前面没有小级别be动词(稍作分析可知was非exhibited的be动词)，于是exhibitedby Massachusetts and Connecticut 为过去分词作thecultural patterns的后置定语。
这时我们可确定was为全句谓语动词。
注意到butalso后的of most other early modernBritishcolonies…and New Hampshire作characteristic的后置定语，其中fromBarbados north to RhodeIsland and New Hampshire作colonies的后置定语;最后，我们来看主语。
whatin contrast to the Puritan colonies appears to Davis to bepeculiarly Southern 中包含了S+V格式，为明显的主语从句。
acquisitiveness,a strong interest inpolitics and the law, and a tendency to cultivatemetropolitan cultural models三个并列的结构形成了主语从句的三个同位语。
这一点很罕见，我们见到的大多数同位语跟在名词后。
这个句子稍繁杂之处在于我们的阅读过程被主语后的连续三个同位语打断，且表语部分有稍多的修饰成分。
但只要我们从分析动词入手，挑出整句谓语动词，整句的主谓以及主干就会清晰显现。
托福阅读长难句2我们知道一个句子的主干(主谓宾)相当于它的骨架，识别了主干相当于抓住了句子的主要信息;而句子的其他修饰、说明及补充的部分(定状补同等)则相当于句子的血肉，血肉中往往包含了大量的附加信息。
很多时候这些附加的信息对整句的理解起着辅助、加强甚至不可或缺的作用。
教学中笔者发现下面这个句子常常困扰一些语法功底不错的考生：The physicist rightly dreads preciseargument, since an argument that isconvincing only if it is precise loses all its force if theassumptions on whichit is based are slightly changed, whereas an argument thatis convincingthoughimprecise may well be stable under small perturbations ofits underlying assumptions.本句since之前的部分含有标准的S(Thephysicist)+V(dreads)+O(argument)结构，而since之后明显应该是原因状语(从句)的部分，所以句首的SVO就是整句的主句。
下面我们来仔细分析since后面的部分：第一行末尾的that紧跟an argument之后，显然做an argument的后置定语从句。
that is convincing是一个完整的主系表结构，only if 则引导了这个定语从句自身的(即小级别)条件状语从句it is precise (仍是一个完整的主系表结构);接下来我们遇到了loses，since到loses之间是两个主系表从句，有各自的系动词，于是loses不属于这两个从句，只能与an argument对应，这一点也可从单复数上佐证。
loses 与后面的all its force 形成动宾结构，其中it 指代前文的anargument;接下来的if引导了条件状语从句theassumptions on which it is based are slightlychanged。
其中on which it is based 做theassumptions的后置定语从句，同样的,it指前文的anargument。
忽略定语从句，我们得到ifthe assumptions are slightly changed;whereas后thatis convincing thoughimprecise紧跟着anargument后做它的后置定语从句。
忽略掉它我们得到whereas anargument may well be stableunder small perturbations of its underlyingassumptions.至此since直到结尾我们已拆解完毕。
即since后是个由whereas 分割连接的并列句，这个并列句前一个子句的主语argument后跟了定语从句，且这个定语从句有自己的小一个级别的条件状语从句onlyifit is precise。
同时第一个子句本身也有自己的条件状语从句ifthe assumptions on which it is based areslightly changed;whereas后出现了第二个子句，这个子句的主语anargument同样带了自己的后置定语从句。
从since到结尾的大级别原因状语从句包含了两个并列子句、两个后置定语从句和两个条件状语从句(不同级别)。
多个从句的层层嵌套增加了我们读懂整句的难度，但只要我们仔细梳理和分解，层层展开，理清各个从句、成分的作用，最终，这种难度的长句还是可以攻克的。
托福阅读长难句3依然记得科比最经典那段对话：记者问：“你为什么能如此成功呢?”科比反问道：“你知道洛杉矶凌晨四点钟是什么样子吗?”记者摇摇头：“不知道，那你说说洛杉矶每天早上四点钟究竟什么样儿?”科比挠挠头，说：“满天星星，寥落的灯光，行人很少。
”科比本周四将会引来最后一场比赛，这是一个时代的结束。
科比、麦迪、卡特、艾佛森、皮尔斯、邓肯、帕克、吉诺比利……谢谢他们带我们青春的记忆。
同学们，第二十四句来了。
世界本没有长难句，修饰成分多了，便有了长难句。
——老邪阅读速度大部分来于短时间内理解长难句的能力。
大家在看长难句的时候，多思考，一个句子为什么这么长，常见的修饰成分到底有哪些?其实不多，连词、非谓语动词、介词以及同位语或插入语，上过课的同学懂得。
大家别急，把一句一句弄明白，弄懂一个句子胜过模糊看懂十个句子。
希望大家认真看我的分析。
今天我们来看这样一个句子：Over long periods of time, substances whose physical and chemical properties change with the ambient climate at the time can be deposited in asystematic way to provide a continuous record of changes in those propertiesovertime, sometimes for hundreds or thousands of years. (TPO10, 44) property /pr?p?t?/ n. 财产，资产;特质，性质;ambient /?mb??nt/ adj. (指空气等)环绕四周的, 周围的我是分界线，大家先自己分析哦。
