托福阅读长难句(第2期)
托福阅读长难句（第2期）—实例分析1在托福阅读考试中，长难句一直是难点，也是让很多同学头疼的地方。
面对又长又复杂的句子时应该怎么办？以下是成萌老师总结的阅读实例，为各位同学详细的讲解。
阅读TPO32-1Plant Colonization植物移生1、Success in colonization depends to a great extent on there being a site available for colonization – a safe site where disturbance by fire or by cutting down of trees has either removed competing species or reduced levels of competition and other negative interactions to a level at which the invading species can become established.解析：这句话的难度在于连字符后的同位语句子，a site available for colonization 和a safe site是同位语，棋后的定语从句中主要动词是either removed…or reduced…to…，难点在于明确…or…，either…or…，…and…各自的并列成分。
连字符前的there being a site available for colonization做宾语。
to a great extent的搭配表示“在很大程度上”，作为副词性介词短语修饰动词depend，类似的表达有to some degree, in some measure, to some point, in some part. 生物学中的colonization不能翻译成“殖民”，而是指“ (动、植物)移植，移生，移地发育”。

托福备考托福阅读34套TPO样题+解析+译文TPO2--2 Desert Formation
托福考试 复习托福阅读TPO2(试题+答案+译文)第2篇:Desert Formation托福阅读原文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 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.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. Waterabsorption 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: over cultivation, overgrazing, firewood gathering, and over irrigation. 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 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.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 useof 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 over irrigation. 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.托福阅读试题1.

▉托福TPO2阅读Passage2原文文本： The Origins of Cetaceans It should be obvious that cetaceans-whales, porpoises, and dolphins-are mammals. They breathe through lungs, not through gills, and give birth to live young. Their streamlined bodies, the absence of hind legs, and the presence of a fluke and blowhole cannot disguise their affinities with land dwelling mammals. However, unlike the cases of sea otters and pinnipeds (seals, sea lions, and walruses, whose limbs are functional both on land and at sea), it is not easy to envision what the first whales looked like. Extinct but already fully marine cetaceans are known from the fossil record. How was the gap between a walking mammal and a swimming whale bridged? Missing until recently were fossils clearly intermediate, or transitional, between land mammals and cetaceans. Very exciting discoveries have finally allowed scientists to reconstruct the most likely origins of cetaceans. In 1979, a team looking for fossils in northern Pakistan found what proved to be the oldest fossil whale. The fossil was officially named Pakicetus in honor of the country where the discovery was made. Pakicetus was found embedded in rocks formed from river deposits that were 52 million years old. The river that formed these deposits was actually not far from an ancient ocean known as the Tethys Sea. The fossil consists of a complete skull of an archaeocyte, an extinct group of ancestors of modern cetaceans. Although limited to a skull, the Pakicetus fossil provides precious details on the origins of cetaceans. The skull is cetacean-like but its jawbones lack the enlarged space that is filled with fat or oil and used for receiving underwater sound in modern whales. Pakicetus probably detected sound through the ear opening as in land mammals. The skull also lacks a blowhole, another cetacean adaptation for diving. Other features, however, show experts that Pakicetus is a transitional form between a group of extinct flesh- eating mammals, the mesonychids, and cetaceans. It has been suggested that Pakicetus fed on fish in shallow water and was not yet adapted for life in the open ocean. It probably bred and gave birth on land. Another major discovery was made in Egypt in 1989. Several skeletons of another early whale, Basilosaurus, were found in sediments left by the Tethys Sea and now exposed in the Sahara desert. This whale lived around 40 million years ago, 12 million years after Pakicetus. Many incomplete skeletons were found but they included, for the first time in an archaeocyte, a complete hind leg that features a foot with three tiny toes. Such legs would have been far too small to have supported the 50-foot-longBasilosaurus on land. Basilosaurus was undoubtedly a fully marine whale with possibly nonfunctional, or vestigial, hind legs. An even more exciting find was reported in 1994, also from Pakistan. The now extinct whale Ambulocetus natans ("the walking whale that swam") lived in the Tethys Sea 49 million years ago. It lived around 3 million years after Pakicetus but 9 million before Basilosaurus. The fossil luckily includes a good portion of the hind legs. The legs were strong and ended in long feet very much like those of a modern pinniped. The legs were certainly functional both on land and at sea. The whale retained a tail and lacked a fluke, the major means of locomotion in modern cetaceans. The 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. The large hind legs were used for propulsion in water. On land, where it probably bred and gave birth, Ambulocetus may have moved around very much like a modern sea lion. It was undoubtedly a whale that linked life on land with life at sea. ▉托福TPO2阅读Passage2题目： Question 1 of 13 In paragraph 1, what does the author say about the presence of a blowhole in cetaceans? A.

托福阅读TPO2答案解析
托福阅读TPO2(试题+答案+译文)第3篇:Early Cinema托福阅读答案1-6.CBCBCD7-12.ADBAAD13.CEF托福阅读译文电影院的播放技术从最初的西洋镜形式演变为将影像投影到幽暗的影院屏幕，这一转变使得电影院大众化消费成为可能。
在通过西洋镜播放电影的年代里，人们只能通过播放仪器的一个专门设置的小窗口来看电影。
到了1894 年，托马斯•爱迪生发明的活动电影放映机公布于众，这种放映机仅适用于活动电影放映室或电影娱乐城。
它里面仅包含少量的独立播放器，每次仅允许一个顾客观看一部50 张胶卷的小短片。
第一个电影放映厅的放映机中有五台播放器。
价格是25 美分/次，（每台播放器观看价格是5 美分）。
观众们从一个播放器换到下一个播放器依次观看不同的影片（就像有名的职业拳击赛，每场都要连续进行好几轮比赛）。
这些电影播放厅是仿照留声机播放厅设计的，这也证明了爱迪生前几年的设计非常成功。
在留声机播放厅中，顾客们通过独立的耳管听取已经录制好的声音，从一台机器换到另一台听取不同演讲或音乐的录音。
电影放映室的功能与之类似。
相比之下，爱迪生对这些电影放映机（每台一千美元）的销售更感兴趣，而不是那些需要放映的电影（每部10-15 美元）。
他不愿研究投影技术，因为他认为如果研发并且销售投影机，电影放映者就只会买一台投影机而不是几台。
然而，电影放映者们期望将自己的收益最大化，他们希望能更简易地将少量电影同时放映给几百个顾客（而不是每次为一个顾客播放一次电影），每次收费25到50 美分。
在1894 年电影放映机公布的一年之后，摄影师如Louis 和Auguste Lumiere，Thomas Armat 和Charles Francis Jenkins，Orville 和WoodvilleLatham 以及爱迪生先前的助手William Dickson 将投影设备变得更加完善。
这些早期的投影机在众多场合为大众观众播放电影，如：杂技剧团、正当的影院、当地镇上的礼堂、临时的影院店面、露天游乐场和游乐园等。

请分析下面这个例句：>I ti si mp or ta nt tha t st ud en ts un de rst a nd th ei mp or ta nce o ft im em a na ge me nt if th eyw a nt to su cc ee d.这个句子的主句是“I t is im po rt an t”，从句是“t ha ts tu de nt su nd e rs ta nd th ei mp ort a nc eo ft im em an age m en ti ft he y wa nt to su cc ee d”，注意从句中的主谓一致现象。
1.3长难句例题3有时候，长难句会通过添加让步状语从句来增加句子的复杂度和意义。
请分析下面这个例句：>D es pi te be in gt ire d,I de ci de dt og ofo r ar un.这个句子中，“D esp i t e be in gt ir ed”是一个让步状语从句，它表达了尽管疲倦，但我还是决定去跑步的意思。

托福TPO1-6阅读长难句整理智课⽹TOEFL备考资料托福TPO1-6阅读长难句整理摘要：托福TPO是考⽣备考托福的必备材料。
想要提⾼托福阅读能⼒，很多考⽣会选择托福TPO作为练习材料。
⽽TPO阅读中常常出现长难句，解析困难，成为阅读障碍。
因此集中决绝TPO中的长难句就成为迫在眉睫的问题。
⼏乎所有考⽣都会采⽤TPO来练习托福阅读，在TPO阅读中⼀直困扰考⽣的难题⽆⾮就是⽣词和长难句，对于⽣词我们可以通过提⾼词汇量来解决，⽽对于长难句除了不断练习分析外并没有什么特别好的办法。
TPO1：Groundwater1. The same thing happens to this day, though on a smaller scale, wherever asediment-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, depositingthe sediment in the form of a smooth, fan-shaped slope.2. Sediments are also dropped where a river slows on entering a lake or the sea, thedeposited sediments are on a lake floor or the seafloor at first, but will be located inlandat some future date, when the sea level falls or the land rises; such beds are sometimesthousands of meters thick.3. In lowland country almost any spot on the ground may overlie what was once the bedof a river that has since become buried by soil; if they are now below the water's uppersurface (the water table)， the gravels and sands of the former riverbed, and its sandbars,will be saturated with groundwater.4. This is because the gaps among the original grains are often not totally plugged withcementing chemicals; also, parts of the original grains may become dissolved bypercolating groundwater, either while consolidation is taking place or at any timeafterwards.5. But note that porosity is not the same as permeability, which measures the ease withwhich water can flow througha material; this depends on the sizes of the individualcavities and the crevices linking them.6. If the pores are large, the water in them will exist as drops too heavy for surface tensionto hold, and it will drain away; but if the pores are small enough, the water in them willexist as thin films, too light to overcome the force of surface tension holding them inplace; then the water will be firmly held.TPO2：Desert Formation1. 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.2. In areas where considerable soil still remains, though, a rigorously enforced programof land protection and cover-crop planting may make it possible to reverse the present deterioration of the surface.TPO2：The Origins of Cetaceans1. However, unlike the cases of sea otters and pinnipeds (seals, sea lions, and walruses, whose limbs are functionalboth on land and at sea)， it is not easy to envision what the first whales looked like.2. The 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.TPO3：Architecture1. In order for the structure to achieve the size and strength necessary to meet its purpose, architecture employs methods of support that, because they are based on physical laws,have changed little since people first discovered them—even while building materials have changed dramatically.2. The arch was used by the early cultures of the Mediterranean area chiefly for underground drains, but it was the Romans who first developed and used the arch extensively in aboveground structures.TPO3：Depletion of the Ogallala Aquifer1. Estimates indicate that the aquifer contains enough water to fill Lake Huron, but unfortunately, under the semiarid climatic conditions that presently exist in the region, rates of addition to the aquifer are minimal, amounting to about half a centimetera year.2. This unprecedented development of a finite groundwater resource with an almost negligible natural recharge rate—that is, virtually no natural water source to replenish the water supply—has caused water tables in the region to fall drastically.3. The incentive of the farmers who wish to conserve water is reduced by their knowledge that many of their neighbors are profiting by using great amounts of water, and in the process are drawing down the entire region's water supplies.TPO4：Cave Art in Europe1. The researchers Peter Ucko and Andree Rosenfeld identified three principal locations of 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.2. 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.3. Consistent with this idea, according to the investigators, is the fact that the art of the cultural period that followed the Upper Paleolithic also seems to reflect how people got their food.TPO4：Deer Populations of the Puget Sound1. 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。

【必备资料】托福TPO阅读长难句解析及专项训练（二）
在以下的内容中为大家整理了具有代表意义的托福阅读长难句，给出了专业的语法解析、原句翻译及意群训练，作为托福备考的重要资料。
考生可以通过这些长难句的专项训练，迅速掌握阅读长难句的理解方法和做题技巧。
In order for the structure to achieve the size and strength necessary to meet
its purpose, architecture employs methods of support that, because they are
based on physical laws, have changed little since people first discovered
them—even while building materials have changed dramatically.
托福阅读长难句类型：复杂状语+复杂句子结构+插入成分+不明显的倒装+抽象名词
虽然表面看来这个句子没有什么生词，但是这个句子理解起来并不容易，因为这个句子中出现的单词都是比较抽象的单词，例如 structure, achieve,
size, strength, purpose, method,
所以读句子的时候让人觉得不舒服。
句子开头就是一个目的状语，但是这个状语很长，让同学们搞不清楚谁是为了实现谁。
主句结构是 architecture employs
methods of support，但是随后作者又用 that 引导了一个定语从句来修饰 method,并且在定语从句一开始，that
后面直接用because 引导了一个插入的句子，割裂了定语从句。
所以完整的复合句是这样的：architecture employs methods of
support that have changed little since people first discovered them，到此处作者仍不肯收手，用
even while 引导了最后一个从句和定语从句做对比。
于是整个句子的结构就变的十分混乱了。
实际上because they are based on
physical laws 在句子中位置稍作调整，同学们就可以比较清楚的理解这句话了：architecture employs methods of
support that have changed little since people first discovered them, because
they are based on physical laws.
所以本句意思是“建筑学上采用了一些支撑的方法，这些支撑的方法自它们被人类发现以来就鲜有变化，因为它们是建立在物理定律上的”。
作者隐含的意思是物理定律不变，所以这些方法不变。
译文：
建筑结构必须达到大小和强度的要求，以实现必要的建筑目的，因此建筑学上采用一些支撑的方法，这些方法都是以物理定律为基础的，尽管建筑材料已经发生了翻天覆地的变化，这些支撑的方法却自人们发现它们以来就鲜有变化。
