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.

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.

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.

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.

托福阅读和gre阅读难度比较
托福阅读和gre阅读难度比较托福和gre常常被人纳爱作比较，那么托福阅读和gre阅读哪个难度比较高?下面小编就给大家分享一下!托福阅读和gre阅读难度比较不少同学诉苦GRE阅读很难，因为生词很多。
但其实，GRE阅读难度高，并不主要体现在生词上，而是在行文的转折上。
相对TOEFL阅读的“顺风顺水”，一条主线通到底。
比如前文说小A是好人，后文会分三种情况讨论小A是好人。
而GRE阅读内容会出现转折。
比如前半部分说小鸣是好人，画风一转，提到“尽管小鸣是好人，但一些评论家给出了不同的意见”，开始讨论不好的事儿了。
这样的转换其实才是最影响我们判断的地方。
很多时候，GRE短阅读比长阅读更难，不是因为短阅读的单词难，而是因为短阅读的转折有时会更隐蔽，更“委婉”;不知不觉，文章的正态度就变成负态度了，就会严重影响我们的思路。
GRE阅读为什么比TOEFL阅读难这么多?下面我们来看一看这2段节选自一道逻辑单题的内容，同学们在阅读的时候可以思考一下两段文字之间的态度关系。
In the country of Seligia, the use of asbestos is about to be banned, because the exposure of construction workers to asbestos can cause cancer. We can predict that the ban will result in reducing cancer in Seligia by as much as 50 percent.It is true that less than 30 percent of the death certificates of Seligians who have died of cancer have “construction” listed as the occupation . The cancer takes about 20 years after exposure to develop, however, and Seligians who have worked in construction turn to other occupations as they age. Seligian death certificates indicate only the deceased’s last occupation.第二段第一句的"True" 看起来是正态度，只有第二句"However"构成取反，于是有同学会认为第二段反驳第一段。
托福阅读长难句核心技巧之分词定语
托福阅读长难句核心技巧之分词定语长难句是托福阅读的一大特色，虽说我们在考试时不用每句都读懂，但很多时候长难句本身就是出题信息点，这就要求考生必须具备破解它们的能力。
下面，我给大家介绍一个破解长难句的关键技巧“分词定语”。
分词是ETS 最喜欢的定语修饰成分，它一共分两类，现在分词doing和过去分词done，根本区别在于doing 表示主动和进行，done 表示被动和完成。
它们做定语时的共同特点是单个的现在和过去分词做定语都放在所修饰词的前面，而短语的现在和过去分词则放在所修饰词的后面。
区别是doing 表示主动和进行，done 表示被动和完成。
分词定语的核心是两个阅读技巧，请大家牢记。
第一个是一个固定结构：A done 介词B, 凡是在文中看到后我们要马上意识到这是一个修饰A 的过去分词定语，也就是后面修饰前面，从后往前读。
第二个技巧是：一个名词后直接加上 doing , 是现在分词定语，同样是后面修饰前面，从后往前读。
例如在TPO24 中有这样一个句子：The environmental changes associated with this transition are not fully understood, but people living closest to the San Juan Mountains, to the northeast of Mesa Verde, were affected first.根据我们之前两条技巧不难看出，其中The environmental changes associated with this transition 是A done 介词B 的过去分词定语，从后往前修饰，意思是与这个转变相关的环境变化。
而people living closest to the San Juan Mountains 属于名词后直接加上doing 的现在分词定语，意思是住在离San Juan Mountains, 最近的人。
托福阅读paraphrase题型解题思路技巧实例分析通用4篇
托福阅读paraphrase题型解题思路技巧实例分析通用4篇托福考试阅读长难句解析篇一Their competition and collaboration werecreating the broadcasting industry in the United States, beginning with theintroduction of commercial radio programming in the early 1920s.记忆单词：competition n.比赛competitor n.参赛者competent adj.有能力的competence n.能力collaboration n.合作collaborate v.合作commercial adj.商业的commodity n.商品理解句子：此句结构清晰，划线部分为分词作状语。
托福阅读paraphrase题型解题思路技巧实例分析篇二托福阅读中的paraphrase问题如何应对？在托福阅读中，还有一类题型经常出现，那就是paraphrase。
这类问题需要大家在给出的选项选择与文章中的长难句意义相近的一句话。
这类问题还是有一定难度的，因为选项中存在一些干扰项。
那么这类问题有哪些解题技巧呢？Strategies to answer this question：1、划分句子主谓宾，充分理解句子意思；2、将句子大意用自己的话复述一遍，简化句子成分；3、看问题选项中有没有跟刚复述的句子意义相似的句子；4、选出正确答案后，看一下其他错误选项。
这些错误选项有的意思跟原文不同，有的漏掉了原文中的重要内容。
找出这些错误，确保万无一失。
Example:大家先来看一个例子：Rather than sell the painting, which is most likely worthmillions of dollars, the Jesuits decided to make it available to the nation of Ireland for viewing. Thus, the painting is on “indefinite loan” to the National Gallery of Ireland. Nevertheless, the painting continues its travels as it features in exhibitions around the world, from the United States to Amsterdam.Which of the sentences below best expresses the essential information in the highlighted sentence?a. The National Gallery of Ireland now owns the painting.b. The National Gallery of Ireland bought the painting from the Jesuits.c. The National Gallery of Ireland can display the painting, but the Jesuits still own it.d. The National Gallery of Ireland can display the painting as long as they allow it to travel.想要回答正确，就要准确理解文中indefinite loan的意思。
