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”。

今天，小编分享给大家的是关于TPO4Deer Populations of the Puget Sound的题目分析。
Deer Populations of the Puget Sound普吉特海湾的鹿群Paragraph1:Two 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.1.According to paragraph1,which of the following is true of the white-tailed deer of Puget Sound?○It is native to lowlands and marshes.○It is more closely related to the mule deer of eastern Washington than to other types of deer.○It has replaced the black-tailed deer in the open prairie.○It no longer lives in a particular type of habitat that it once occupied.解析：答案是(4)，事实信息题由the white-tailed deer of Puget Sound定位到The other species,the Columbianwhite-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.选项(1)和it is now restricted to the low,marshy islands矛盾；选项(2)是对另一种black-tailed deer的描述；选项(3)没有提到，文章是说“was common in the open prairie country”没有和the black-tailed deer对比；选项(4)正确。

分句1：The largest rose in five terraced stories，contained more than 800 rooms，and could have housed a population of 1，000 or more;分句2：later named Pueblo Bonito(Pretty Town)by the Spanish。
分句1嵌套了分句2，分句1的主语是the largest, 这是“the + 形容词”表示一个名词的结构，相当于“the largest one" 的省略的说法。
分句2是省略了“which was" 的定语从句，用来修饰分句1的主语the largest, 分句1内部是由三个并列的谓语构成的句子。

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.

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。
