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。

精选400句托福阅读长难句(OG & TPO)第一类1.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.2.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.3.But note that porosity is not the same aspermeability, 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.4.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.5.But the myths that have grown up around the rites may continue as part of the group’s oral tradition and may even come to be acted out under conditions divorced from these rites.6.Another, advanced in the twentieth century, suggests that humans have a gift for fantasy, through which they seek to reshape reality into more satisfying forms than those encountered in daily life.7.For example, one sign of this condition is theappearance of the comic vision, since comedy requires sufficient detachment to view some deviations from social norms as ridiculous rather than as serious threats to the welfare of the entire group.8.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.9.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.10.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.11.Wind velocity also increases with altitude and may cause serious stress for trees, as ismade evident by the deformed shapes at high altitudes.12.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.13.Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.14.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.15.In order for the structure to achieve thesize and strength necessary to meet its purpose, architecture employs methods of support that, because they are based on physical laws, have changed little since people first discovered them-even while building materials have changed dramatically.16.Some of the world’s finest stone architecture can be seen in the ruins of the ancient Inca city of Machu Picchu high in the eastern Andes Mountains of Peru.17.It works in compression to divert the weight above it out to the sides, where the weight is borne by the vertical elements on either side of the arch.18.The Ogallala aquifer is a sandstone formation that underlies some 583,000 square kilometers of land extending from northwestern Texas to southern South Dakota.19.Unfortunately, the cost of water obtained through any of these schemes wouldincrease pumping costs at least tenfold, making the cost of irrigated agricultural products from the region uncompetitive on the national and international markets. 20.Whatever the final answer to the water crisis may be, it is evident that within the High Plains, irrigation water will never again be the abundant, inexpensive resource it was during the agricultural boom years of the mid-twentieth century.21.To take an extreme example, farmlands dominated by a single crop are so unstable that one year of bad weather or the invasion of a single pest can destroy the entire crop.22.Ecologists are especially interested to know what factors contribute to the resilience of communities because climax communities all over the world are being severely damaged or destroyed by human activities.23.The destruction caused by the volcanic explosion of Mount St. Helens, in thenorthwestern United States, for example, pales in comparison to the destruction caused by humans.24.Many ecologists now think that the relative long-term stability of climax communities comes not from diversity but from the ―patchiness‖ of the environment, an environment that varies from place to place supports more kinds of organisms than an environment that is uniform.25.Similarly, a plant or animal cannot squander all its energy on growing a big body if none would be left over for reproduction, for this is the surest way to extinction.26.At the other extreme are ―competitors,‖ almost all of whose resources are invested in building a huge body, with a bare minimum allocated to reproduction.27. A new plant will spring up wherever a seed falls on a suitable soil surface, but because they do not build big bodies, theycannot compete with other plants for space, water, or sunlight.28.These plants are termed opportunists because they rely on their seeds’ falling into settings where competing plants have been removed by natural processes, such as along an eroding riverbank, on landslips, or where a tree falls and creates a gap in the forest canopy.29.Human landscapes of lawns, fields, or flowerbeds provide settings with bare soil and a lack of competitors that are perfect habitats for colonization by opportunists. 30. A massive oak claims its ground for 200 years or more, outcompeting all other would-be canopy trees by casting a dense shade and drawing up any free water in the soil.31.It should be noted, however, that the pure opportunist or pure competitor is rare in nature, as most species fall between the extremes of a continuum, exhibiting a blendof some opportunistic and some competitive characteristics.32.Because some paintings were made directly over others, obliterating them, it is probable that a painting’s value ended with the migration it pictured.33.One Lascaux narrative picture, which shows a man with a birdlike head and a wounded animal, would seem to lend credence to this third opinion, but there is still much that remains unexplained.34.Perhaps so much time has passed that there will never be satisfactory answers to the cave images, but their mystique only adds to their importance.35.In 1994 there were nearly 20,000 wind turbines worldwide, most grouped in clusters called wind farms that collectively produced 3,000 megawatts of electricity. 36.Most were in Denmark (which got 3 percent of its electricity from wind turbines) and California (where 17,000 machinesproduced 1 percent of the state’s electricity, enough to meet the residential needs of a city as large as San Francisco).37.In the long run, electricity from large wind farms in remote areas might be used to make hydrogen gas from water during periods when there is less than peak demand for electricity.rge wind farms might also interfere with the flight patterns of migratory birds in certain areas, and they have killed large birds of prey (especially hawks, falcons, and eagles) that prefer to hunt along the same ridge lines that are ideal for wind turbines.39.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 1832.40.The researchers Peter Ucko and Andree Rosenfeld identified three principal locationsof paintings in the caves of western Europe: (1) in obviously inhabited rock shelters and cave entrances; (2) in galleries immediately off the inhabited areas of caves; and (3) in the inner reaches of caves, whose difficulty of access has been interpreted by some as a sign that magical-religious activities were performed there.41.Perhaps, like many contemporary peoples, Upper Paleolithic men and women believed that the drawing of a human image could cause death or injury, and if that were indeed their belief, it might explain why human figures are rarely depicted in cave art.42.For example, wild cattle (bovines) and horses are portrayed more often than we would expect by chance, probably because they were larger and heavier (meatier) than other animals in the environment.43.Consistent with this idea, according to the investigators, is the fact that the art of thecultural period that followed the Upper Paleolithic also seems to reflect how people got their food.44.But in that period, when getting food no longer depended on hunting large game animals (because they were becoming extinct), the art ceased to focus on portrayals of animals.45.When the well reaches a pool, oil usually rises up the well because of its density difference with water beneath it or because of the pressure of expanding gas trapped above it.46.More than one-quarter of the world’s oil and almost one-fifth of the world’s natural gas come from offshore, even though offshore drilling is six to seven times more expensive than drilling on land.47.While there are a dozen or more mass extinctions in the geological record, the Cretaceous mass extinction has always intrigued paleontologists because it marksthe end of the age of the dinosaurs.48.The explosion lifted about 100 trillion tons of dust into the atmosphere, as can be determined by measuring the thickness of the sediment layer formed when this dust settled to the surface.49.Such a quantity of material would have blocked the sunlight completely from reaching the surface, plunging Earth into a period of cold and darkness that lasted at least several months.50.The explosion is also calculated to have produced vast quantities of nitric acid and melted rock that sprayed out over much of Earth, starting widespread fires that must have consumed most terrestrial forests and grassland.51.Following each mass extinction, there is a sudden evolutionary burst as new species develop to fill the ecological niches opened by the event.52.Earth is a target in a cosmic shootinggallery, subject to random violent events that were unsuspected a few decades ago.53.Early in the century, a pump had come into use in which expanding steam raised a piston in a cylinder，and atmospheric pressure brought it down again when the steam condensed inside the cylinder to forma vacuum．54.The final step came when steam was introduced into the cylinder to drive the piston backward as well as forward thereby increasing the speed of the engine and cutting its fuel consumption.55.Iron manufacturers which had starved for fuel while depending on charcoal also benefited from ever-increasing supplies of coal; blast furnaces with steam- powered bellows turned out more iron and steel for the new machinery.56.He received rudimentary village schooling but mostly he roamed his uncle's farm collecting the fossils that were so abundantin the rocks of the Cotswold hills．57.The companies building the canals to transport coal needed surveyors to help them find the coal deposits worth mining as well as to determine the best courses for the canals.58.In 1831 when Smith was finally recognized by the Geological Society of London a s the ―father of English geology‖, it was not only for his maps but also for something even more important．59.Maturation of the frontal lobes of the brain continues throughout early childhood, and this part of the brain may be critical for remembering particular episodes in ways that can be retrieved later.60.Demonstrations of infants’ and toddlers' long-term memory have involved their repeating motor activities that they had seen or done earlier，such as reaching in the dark for objects, putting a bottle in a d oll’s mouth, or pulling apart two pieces of a toy.61.Through hearing stories with a clear beginning，middle, and ending children may learn to extract the gist of events in ways that they will be able to describe many years later.62.The world looks very different to a person whose head is only two or three feet above the ground than to one whose head is five or six feet above it, 0lder children and adults often try to retrieve the names of things they saw, but infants would not have encoded the information verbally．63.General knowledge of categories of events such as a birthday party or a visit to the doctor's office helps older individuals encode their experiences, but again, infants and toddlers are unlikely to encode many experiences within such knowledge structures．64.Physiological immaturity may be part of why infants and toddlers do not form extremely enduring memories, even whenthey hear stories that promote such remembering in preschoolers.65.In 1947 Norwegian adventurer Thor Heyerdahl drifted on a balsa-log raft westward with the winds and currents across the Pacific from South America to prove his theory that Pacific islanders were Native Americans (also called American Indians).66.Contrary to the arguments of some that much of the pacific was settled by Polynesians accidentally marooned after being lost and adrift, it seems reasonable that this feat was accomplished by deliberate colonization expeditions that set out fully stocked with food and domesticated plants and animals.67.The undisputed pre-Columbian presence in Oceania of the sweet potato, which is a New World domesticate, has sometimes been used to support Heyerdahl’s ―American Indians in the Pacific‖ theories.68.As Patrick Kirch, an American anthropologist, points out, rather than being brought by rafting South Americans, sweet potatoes might just have easily been brought back by returning Polynesian navigators who could have reached the west coast of South America.69.Conditions that promote fossilization of soft-bodied animals include very rapid covering by sediments that create an environment that discourages decomposition.70.This 700-million-year-old formation gives few clues to the origins of modern animals, however, because paleontologists believe it represents an evolutionary experiment that failed.71.At one time, the animals present in these fossil beds were assigned to various modern animal groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms that arose inthe early Cambrian period and disappeared before the end of the period, leaving no descendants in modern animal groups. 72.These fossil beds provide evidence of about 32 modern animal groups, plus about 20 other animal body forms that are so different from any modern animals that they cannot be assigned to any one of the modern groups.73.With question such as these clearly before them, the scientists aboard the Glomar Challenger processed to the Mediterranean to search for the answers.74.In all probability it was the fertile plain of Latium, where the Latins who founded Rome originated, that created the habits and skills of landed settlement, landed property, landed economy, landed administration, and a land-based society.75.Agriculture seems to have reached these people from the Near East, since the first domesticated crops were millets andsorghums whose origins are not African but west Asian.76.Most of Africa presents a curious case in which societies moved directly from a technology of stone to iron without passing through the intermediate stage of copper or bronze metallurgy, although some early copper-working sites have been found in West Africa.77.They spoke a language, prior-Bantu (―Bantu‖ means ―the people‖), which is the parent tongue of a language of a large number of Bantu languages still spoken throughout sub-Sahara Africa.78.Why and how these people spread out into central and southern Africa remains a mystery, but archaeologists believe that their iron weapons allowed them to conquer their hunting-gathering opponents, who still used stone implements.79.With Cuicuilco eliminated as a potential rival, any one of a number of relativelymodest towns might have emerged as a leading economic and political power in Central Mexico.80.The hard volcanic stone was a resource that had been in great demand for many years, at least since the rise of the Olmecs (a people who flourished between 1200 and 400 B.C.), and it apparently had a secure market.81.Moreover, recent research on obsidian tools found at Olmecs sites has shown that some of the obsidian obtained by the Olmecs originated near Teotihuacán.82.The growing power of the elite, who controlled the economy, would give them the means to physically coerce people to move to Teotihuacán and serve as additions to the labor force.83.By measuring how many of these meteorites fall to Earth over a given period of time, scientists can estimate how long it might have taken to deposit the observedamount of lr in the boundary clay.84.They bear a strong resemblance to river systems on Earth, and geologists think that they are dried-up beds of long-gone rivers that once carried rainfall on Mars from the mountains down into the valleys.85.Runoff channels on Mars speak of a time 4 billion years ago (the age of the Martian highlands), when the atmosphere was thicker, the surface warmer, and liquid water widespread.86.The onrushing water arising from these flash floods likely also formed the odd teardrop-shaped ―islands‖ (resembling the miniature versions seen in the wet sand of our beaches at low tide) that have been found on the plains close to the ends of the outflow channels.87.Judging from the width and depth of the channels, the flow rates must have been truly enormous―perhaps as much as a hundred times greater than the 105 tonsper second carried by the great Amazon river.88. A computer-generated view of the Martian north polar region shows the extent of what may have been an ancient ocean covering much of the northern lowlands. 89.Proponents point to features such as the terraced ―beaches‖ shown in one image, which could conceivably have been left behind as a lake or ocean evaporated and the shoreline receded.90.But detractors maintain that the terraces could also have been created by geological activity, perhaps related to the geologic forces that depressed the Northern Hemisphere far below the level of the south, in which case they have nothing whatever to do with Martian water.91.It has long been accepted that the Americas were colonized by a migration of peoples from Asia, slowly traveling across a land bridge called Beringia (now the BeringStrait between northeastern Asia and Alaska) during the last Ice Age.92.The first water craft theory about the migration was that around 11,000-12,000 years ago there was an ice-free corridor stretching from eastern Beringia to the areas of North America south of the great northern glaciers.93.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.94.He theorized that with the use of watercraft, people gradually colonized unglaciated refuges and areas along the continental shelf exposed by the lower sea level.95.Fladmark's hypothesis received additional support from the fact that the greatest diversity in Native Americanlanguages occurs along the west coast of the Americans, suggesting that this region has been settled the longest.96.Vast areas along the coast may have been deglaciated beginning around 16,000 years ago, possibly providing a coastal corridor for the movement of plants, animals, and humans sometime between 13,000 and 14,000 years ago.97.The coastal hypothesis has gained increasing support in recent years because the remains of large land animals, such as caribou and brown bears, have been found in southeastern Alaska dating between 10,000 and 12,500 years ago.98.Fladmark and others believe that the first human colonization of America occurred by boat along the Northwest Coast during the very late Ice Age, possibly as early as 14,000 years ago.99.The most recent geologic evidence indicates that it may have been possible forpeople to colonize ice-free regions along the continental shelf that were still exposed by the lower sea level between 13,000 and 14,000 ago.100.T hey were concerned that many would be drawn to these new, refreshing conceptions of teaching only to find that the void between the abstractions and the realities of teacher reflection is too great to bridge. 101.F urther observation revealed the tendency of teachers to evaluate events rather than review the contributory factors in a considered manner by, in effect, standing outside the situation.102.T he researchers estimate that the initial training of the same teachers to view events objectively took between 20 and 30 hours, with the same number of hours again being required to practice the skills of reflection. 103.T he teachers in the program described how they found it difficult to put aside the immediate demands of others in order togive themselves the time they needed to develop their reflective skills.104.S upport and encouragement were also required to help teachers in the program cope with aspects of their professional life with which they were not comfortable. 105.T he fungi absorb moisture and mineral salts from the rocks, passing these on in waste products that nourish algae.106.L ichens helped to speed the decomposition of the hard rock surfaces, preparing a soft bed of soil that was abundantly supplied with minerals that had been carried in the molten rock from the bowels of Earth.107.By means of these seeds, plants spread more widely to new locations, even to isolated islands like the Hawaiian archipelago, which lies more than 2,000 miles west of California and 3,500 miles east of Japan.108.A lthough we now tend to refer to thevarious crafts according to the materials used to construct them-clay, glass, wood, fiber, and metal-it was once common to think of crafts in terms of function, which led to their being known as the "applied arts." 109.Since the laws of physics, not some arbitrary decision, have determined the general form of applied-art objects, they follow basic patterns, so much so that functional forms can vary only within certain limits.110.T hat this device was a necessary structural compromise is clear from the fact that the cannonball quickly disappeared when sculptors learned how to strengthen the internal structure of a statue with iron braces (iron being much stronger than bronze).111.E ven though the fine arts in the twentieth century often treat materials in new ways, the basic difference in attitude of artists in relation to their materials in the fine artsand the applied arts remains relatively constant.112.P akicetus was found embedded in rocks formed from river deposits that were 52 million years old.113.T he structure of the backbone shows, however, that Ambulocetus swam like modern whales by moving the rear portion of its body up and down, even though a fluke was missing.114.T he 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.115.T he 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.116.D uring 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.117.T he 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.118.T he 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.119.I n 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.120.T he cinema did not emerge as a form of mass consumption until its technology evolved from the initial "peepshow" format to the point where images were projectedon a screen in a darkened theater.121.I t was designed for use in Kinetoscope parlors, or arcades, which contained only a few individual machines and permitted only one customer to view a short, 50-foot film at any one time.122.I n the phonograph parlors, customers listened to recordings through individual ear tubes, moving from one machine to the next to hear different recorded speeches or pieces of music.123.H e refused to develop projection technology, reasoning that if he made and sold projectors, then exhibitors would purchase only one machine-a projector-from him instead of several. 124.B ut the movies differed significantly from these other forms of entertainment, which depended on either live performance or (in the case of the slide-and-lantern shows) the active involvement of a master of ceremonies who assembled the finalprogram.125.A lthough early exhibitors regularly accompanied movies with live acts, the substance of the movies themselves is mass-produced, prerecorded material that can easily be reproduced by theaters with little or no active participation by the exhibitor.126.E ven though early exhibitors shaped their film programs by mixing films and other entertainments together in whichever way they thought would be most attractive to audiences or by accompanying them with lectures, their creative control remained limited.127.W ith the advent of projection, the viewer's relationship with the image was no longer private, as it had been with earlier peepshow devices such as the Kinetoscope and the Mutoscope, which was a similar machine that reproduced motion by means of successive images on individualphotographic cards instead of on strips of celluloid.128.A t the same time, the image that the spectator looked at expanded from the minuscule peepshow dimensions of 1 or 2 inches (in height) to the life-size proportions of 6 or 9 feet.129.T hose individuals who possess characteristics that provide them with an advantage in the struggle for existence are more likely to survive and contribute their genes to the next generation.130.B ecause aggressive individuals are more likely to survive and reproduce, whatever genes are linked to aggressive behavior are more likely to be transmitted to subsequent generations.131.C hildren normally desire to vent aggressive impulses on other people, including their parents, because even the most attentive parents cannot gratify all of their demands immediately.。

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。
【参考翻译】在逆流交换系统中，携带着来自脚蹼冷却血液的血管与携带着来自身体温暖血液的血管足够靠近，这样就可以从更温暖的血管中吸收一些热量；因此，在热量到达脚蹼之前，其从流出身体的血管转移到了流入身体的血管。
【成分划分】并列句一In a countercurrent exchange system,[状语]the blood vessels[主语]carrying cooled blood from the flippers[定语]run[谓语]close enough to the blood vessels [状语]carrying warm blood from the body[定语]to pick up some heat[状语]from the warmer blood vessels.[状语]并列句二The heat[主语]is transferred[谓语]from the outgoing to the ingoing vessels.[状语]状语从句It[主语]reaches[谓语]the flipper[宾语]itself.[状语]句子2If 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.【难点解析】本句的难点是定语（例如too heavy for surface tension to hold）放在了被修饰词（例如drops）的后面，与汉语表述习惯不一致，给我们理解的带来了一定的困难。
另外，后置定语中嵌套了另一个后置定语，更加增加了难度（too light to overcome the force of surface tension[定语]holding them in place.[定语]）。
根据定语的特点（限定或者修饰名词性成分），遇到后置定语，先忽略这些修饰性的定语，找到句子主干，再按照自己的理解，将英语句子切分成一小段一小段来翻译，最后再组合成一句话，这样整句话意思就清晰了。
If the pores are large,the water in them will exist as drops too heavy for surface tension to hold[定语],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[定语]holding them in place[定语];then the water will be firmly held.【参考翻译】如果孔隙很大，其中的水分会以水滴的形态而存在，水滴的重量足以克服表面张力的束缚，随后水分就会渐渐流失；但是，如果孔隙足够小，其中的水会以薄膜形态而存在，薄膜太轻无法克服表面张力的束缚，因此，这种形态的水会稳稳地附着在孔隙表面上。
【成分划分】状语从句The pores[主语]are[系动词]large.[表语]并列句The water[主语]in them[定语]will exist[谓语]as drops[状语]too heavy for surface tension to hold.[定语]并列句It[主语]will drain away.[谓语]状语从句The pores[主语]are[系动词]small enough.[表语]并列句The water[主语]in them[定语]will exist[谓语]as thin films,[状语]too light to overcome the force of surface tension[定语]holding them in place.[定语]并列句The water[主语]will be firmly held.[谓语]句子3The images produced by the camera obscura,a boxlike device that used a pinhole or lens to throw an image onto a ground-glass screen or a piece of white paper, were already familiar—the device had been much employed by topographical artists like the Italian painter Canaletto in his detailed views of the city of Venice.【难点解析】本句的难点是定语（produced by the camera obscura）放在了被修饰词（the images）的后面，与汉语表述习惯不一致，另外，出现同位语（a boxlike device）修饰定语中的名词性部分（the camera obscura），而又有一个定语从句（that used a……）又修饰改同位语（a boxlike device），使得主语和谓语被很多成分隔开，给我们理解的带来了一定的困难。
找到那些修饰性成分，先忽略它们，再看句子主干就清楚了。
The images produced by the camera obscura[定语],a boxlike device[同位语]that used a pinhole or lens to throw an image onto a ground-glass screen or a piece of white paper[定语从句],were already familiar—the device had been much employedby topographical artists like the Italian painter Canaletto in his detailed views of the city of Venice.【参考翻译】针孔照相机（一种盒状的装置）产生的影像已经为大家所熟知，它是一种使用小孔或透镜将影像投射到毛玻璃屏或一张白纸上的盒状装置——这种装置已经为很多地貌风景画家所用，例如意大利画家Canaletto在他所创作的威尼斯精致风景画中（使用了这种装置）。
【成分划分】并列句The images[主语]produced by the camera obscura,[定语]a boxlike device,[同位语] were[系动词]already familiar.[表语]并列句The device[主语]had been much employed[谓语]by topographical artists[状语] like the Italian painter Canaletto in his detailed views of the city of Venice.[同位语]定语从句A boxlike device[主语]used[谓语]a pinhole or lens[宾语]to throw an image onto a ground-glass screen or a piece of white paper.[宾语补足语]句子4A maritime code known as the Consulate of the Sea which originated in the western Mediterranean region in the fourteenth century,won acceptance by a majority of sea goers as the normative code for maritime conduct;it defined such matters as the authority of a ship's officers,protocols of command,pay structures,the rights of sailors,and the rules of engagement when ships met one another on the sea-lanes.【难点解析】本句的难点一是后置定语和定语从句分割了句子主干，造成了理解问题。
