例1 Above the tree line there is a zone that is generally called alpine tundra高山苔原. █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.█Some plants can even survive in favorable microhabitats above the snow line. The highest plants in the world occur at around

6,100 meters on Makalu in the Himalayas.█At this great height, rocks, warmed by the sun, melt small snowdrifts.█

Look at the four squares [█] that indicate where the following sentence could be added to the passage.

例2、█Modern architectural forms generally have three separate components comparable to elements of the human body; a supporting skeleton or frame, an outer skin enclosing the interior spaces, equipment, similar to the body’s vital organs and systems. █The equipment includes plumbing, electrical wiring, hot water, and

air-conditioning. █Of course in early architecture—such as igloos and adobe structures—there was no such equipment, and the skeleton骨架and skin were often one.█

Look at the four squares [█] that indicate where the following sentence could be added to the passage.

However, some modern architectural designs, such as those using folded plates of concreter or air-inflated structures, are again unifying skeleton and skin.

托福阅读错题总结

托福阅读错题总结： 改变计划——从第一套开始做！ TPO24：细节题做完之后，通读文章，了解全文的结构和主要内容层次 一、Lake Water 2、词汇题gains：这里是增量的概念所以应该是increase，而不是存量的概念savings 8、比较细节题：弄清A比B还是B比A，Lake Erie体积小，选择表述相反但正确。 11、解释现象题：定位前后句，前面一句是：Climatic change影响很大，后面一句是： Theslowing down of water renewal leads to a chain of further consequences，由further可以推知Theslowing down of water renewal也是前面现象的原因 14、概括多选题：太细节的不选，没有提到的不选，选项一般是文章几个层次的内容。 同一部分的内容不可能选两个答案。 二、Breathing During Sleep 7、注意题目中的限定during NREM，和文章中的比较转折（往后看） 13、归类题：要理解文章的主要内容，对各部分的内容都要熟悉 三、Moving into Pueblos 1、词汇题：traumatic，外力的，受迫的 3、理解推断题：要理解原文想要表达的意思，原来更加自由 5、细节题：定位对应段的内容，同义句的替换 14、概括多选题：表述过于绝对的选项是不正确的 TPO23：定位，理解，替换（分析定位句，转换含义），不要多想（文中没提到的绝对不选） 一、Urban Climates 11、词汇题：modified（改进的——changed）中性的改变，increased修饰不合理。 定位原句：Wind movements are also modified in cities because buildings increase the friction on air flowing around them. This friction tends to slow the speed of winds。 13、插入句子题：Another possibility is for the heat island to be stretched along the course of major rivers, since large waterways typically have a warming effect on the air directly above them. 原文环境：■The precise configuration of a heat island depends on several factors.■For example, the wind can make a heat island stretch in the direction it blows. ■When a heat island is well developed, variations can be extreme; in winter, busy streets in cities can be 1.7℃warmer than the side streets. ■ 通过标红的词，以及并列的语义：许多原因，例如XX，另一个XX，判断插入第三处。 14、多选题：分析文章的主要内容：城市热的一个现象——这个热是怎么造成的——形 成热岛效应及其特征——城市表面空气造成的其他现象 此题中其他三个选项都是文中没有提到的！ 二、Seventeenth-Century Dutch Agriculture 2、句子同意转述题：Importing the grain, （which would have been expensive and time consuming for the Dutch to have produced themselves）, kept the price of grain low and thus stimulated individual demand for other foodstuffs and consumer goods. 主干：Importing the grainkept the price of grain low and thus stimulated individual demand for other foodstuffs and consumer goods.虽然由and 连接，但其实是因果关系句！ Thus 一词体现出了因果关系！B. Because the Dutch were able to import inexpensive grain, they had money available to create a demand for other food products and consumer

托福阅读解题技巧-句子插入题(一)

托福阅读解题技巧-句子插入题（一） 托福阅读不同于传统阅读，其中包含了”句子插入题”这类特殊题型，这也是托福阅读中相对难得分的题型。此类题型中，题干中会给出一个新的句子，然后会在原文段落中给出四个黑框，考察新句子在文章中最合适的位置。针对于此类题型的解答，有很多实用的方法，今天我们要介绍的是在剩余时间不多的情况下，最简单最便捷的解决方法-语义指代匹配法。 在上下句的关联中，代词是最为紧密的一类词。当作者再次谈及上句相关话题时，为了避免重复，遵循语言学的最简单化原理，作者会用代词指代上文内容，常见指示代词this, that, these, those, 人称代词they, she, he, 或it ，还有their, such, another等。对于此类题型的具体解题步骤如下： ①确认指代对象：根据指代词找到其所指代的对象； ②定位指代对象：通过浏览扫描段落信息，确定指代对象位置； ③代入验证：把插入句代入含有指代对象所在句的后面进行验证即可。 接下来，我们通过具体实例来论证使用语义指代匹配法。 案例： Paragraph 1: Before 1815 manufacturing in the United States had been done in homes or shops by skilled artisans.■As master craft workers, they imparted the knowledge of their trades to apprentices and journeymen. ■In addition, women often worked in their homes part-time, making finished articles from raw material supplied by merchant capitalists. ■After 1815 this older form of manufacturing began to give way to factories with machinery tended by unskilled or semiskilled laborers. ■Cheap transportation networks, the rise of cities, and the availability of capital and credit all stimulated the shift to factory production. 11. Look at the four squares[■]that indicate where the following sentence can be added to the passage. This new form of manufacturing depended on the movement of goods to distant locations and a centralized source of laborers.

托福阅读题型解析之这三类错题原本可以避免

托福阅读题型解析之这三类错题原 本可以避免 托福阅读题型解析, 这三类错题原本可以避免,今天给大家带来了托福阅读题型解析，希望能够帮助到大家，下面就和大家分享，来欣赏一下吧。 托福阅读题型解析这三类错题原本可以避免 托福阅读题型解析一简化题 形成原因： 这种题型可能大家最常见的解决方法就是根据翻译来解题，但是你的翻译正确吗?这就是这种题型错误的主要原因了。 分析及解决方法： 这种题型的正确解题方法应该是利用对句子的理解来解题，而不是靠翻译，再说你的翻译也不一定是正确的。这类题型容易出错的主要原因在于考生往往先对原句进行翻译，然后从选项中找出和原句翻译类似的答案。这样的解题方式的弊端在于浪费时间，而且往往选项翻译都和原句出入不大，在选择时常常出错。

句子简化题的正确做法是利用逻辑解题。使用这种方式不容易出错，因为这种解题方法是从题型考察目的得来的。步骤是：首先看到句子之后的第一个反应是找句子内部的逻辑关系。常见的逻辑关系有两种转折或者因果。举例来说，若原句有转折的逻辑关系，第一步需要做的事情是排掉选项中逻辑关系不对的即不是表示转折的，若选项中还有两个以上逻辑关系都相符合，那么采用的原则是逻辑成分的对应。托福阅读*技巧：这是第一步有逻辑关系的时候采用的方法;如果原句中没有明显的逻辑关系需要采用第二步--提取原句中的主干信息，排掉选项中主干信息不符的选项。 托福阅读题型解析二词汇题 形成原因： 这是托福阅读考试当是出场率较高的一类题型，这种题型的易错原因主要是因为词汇量不足、忽略词汇语境的作用导致的。 分析及解决方法： 对于托福阅读考试当中出现频率较高的题型——词汇题，大部分原因是因为考生的词汇的不足，造成词汇不熟悉或者被选项词给难住了。考生需要知道的是，托福阅读考试词汇题一般考察的是英语六级以上的词汇水平，要想这类题型不出错，那么你的词汇基础就一定要打好。

托福(TOEFL)考试阅读模拟试题(4)

托福（TOEFL）考试阅读模拟试题（4） Questions 11-20 Philosophy in the second half of the 19th century was based more on biology and history than on mathematics and physics. Revolutionary thought drifted away from metaphysics and epistemology and shifted more towards ideologies in science, politics, and sociology. Pragmatism became the most vigorous school of thought in American philosophy during this time, and it continued the empiricist tradition of grounding knowledge on experience and stressing the inductive procedures of experimental science. The three most important pragmatists of this period were the American philosophers Charles Peirce (1839-1914), considered to be the first of the American pragmatists, William James (1842-1910), the first great American psychologist, and John Dewey (1859-1952), who further developed the pragmatic principles of Peirce and James into a comprehensive system of thought that he called “experimental naturalism”, or “instrumentalism”. Pragmatism was generally critical of traditional western philosophy, especially the notion that there are absolute truths and absolute values. In contrast, Josiah Royce (1855-1916), was a leading American exponent of idealism at this time, who believed in an absolute truth and held that human thought and the external world were unified. Pragmatism called for ideas and theories to be tested in practice, assessing whether they produced desirable or undesirable results. Although pragmatism was popular for a time in Europe, most agree that it epitomized the American faith in know-how and practicality, and the equally American distrust of abstract theories and ideologies. Pragmatism is best understood in its historical and cultural context. It arose during a period of rapid scientific advancement, industrialization, and material progress; a time when the theory of evolution suggested to many thinkers that humanity and society are in a perpetual state of progress. This period also saw a decline in traditional religious beliefs and values. As a result, it became necessary to rethink fundamental ideas about values, religion, science, community, and individuality. Pragmatists regarded all theories and institutions as tentative hypotheses and solutions.

托福阅读分数对照表

常常有考友询问，为什么托福阅读明明有42个题，总分却只有30分，分数如何计算的呢？其实，每每看到这种问题，小编的内心是疼痛的。 大家准备一个考试，却不看考试指导手册，考得不太理想，简直太正常了。就算天生神勇，也应该有个作战纲领呀！ 打开OG，第一部分就是托福阅读的介绍，编者首先给出了评分标准的表格。 紧接着给出了各类题型的题型解析，这些就是托福阅读的考察内容，众位考友一定要反复研究，在准备考试时，下意识的按照出题者的思路去解题。 那么托福阅读有些什么考察类型？应该怎么解题？

在iBT阅读中，甚至可以扩展到ETS所有考试的阅读题目中，无论是题干还是正确选项，大都能在原文中找出一句话来与之相对应。即题目是原文的意译。这种意译是通过同义词来完成的。即题干中多用近义词来对原文中的句子进行替换，来达到提出问题或者提出正确答案的意思。准确把握意译，是多数题目中准确在原文中定位信息、或者在迷惑选项中选出正确的那个，都有着重要的作用。 1、词汇题 解题方法：若认识，直接解题，没得说；若不认识，就只能推断了。 但是备考阶段最重要的一点。背单词！首先，考托福没有一定的词汇量等于直接酱油了，所以词汇量是一切的基础。 2、指代题 考点：句子直接词之间的关系 解题方法： （1）代词 a. 从句的主语指代主句的主宾语(使用属性判断,不用含义) b. 关系代词指代先行词(插入结构不影响指代关系) c. 重复概念指代: Tom and his cat(就近原则) d. some 和 others （2）名词 a. 优先选择题干的上下意词 m is a kind of M, M是m的上意词 b. 若上下意词不唯一则当作代词指代处理 注意: a.被指代对象往往在代词之前出现 b. 从句开头往后找答案 c. 代词和被指代对象的数性和性质必须一致 d. 指代的传递现象 3、句子简化题 解题方法： （1）确定题干句子中的逻辑成分 逻辑成分主要包括：关联词，动词，状语 而托福最爱考的逻辑主要是：因果，比较、最高级，否定 （2）确定与逻辑相关的语义 要依据最简化原则，抓句子中的逻辑要素。 因果的逻辑要素是：原因结果 比较的逻辑要素是：比较三要素 最高级 否定的逻辑要素是：作用对象 （3）选择与题干逻辑语义一致的选项 先主后次，从逻辑到语义（千万要保证逻辑正确）

First, at least some of the observed differences between the enzymes of the Atlantic and Pacific fish populations were not random but were the result of evolutionary adaptation. Second, it appears that closely related populations of fishes on both sides of the isthmus are starting to genetically diverge from each other. Because Graves’s study of geographically isolated populations of isthmus fishes offers a glimpse of the beginning of a process of gradual accumulation of mutations that are neutral or adaptive, divergences here might be evidence of allopatric speciation in process. Q12 Which of the sentence 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. A.Graves’s study provides evidence that isthmus fishes are in the process of becoming geographically isolated. B.Graves’s study of mutating isthmus fishes yields results that differ from results of other studies involving allopatric speciation. C.Graves’s study of isolated populations of isthmus fishes provides some evidence that allopatric speciation might be beginning. D.Graves’s study indicates that when isolated, populations of isthmus fishes register neutral or adaptive mutations. 1. 首先确定句子核心信息 Because Graves’s study of geographically isolated populations of isthmus fishes offers a glimpse of the beginning of a process of gradual accumulation of mutations that are neutral or adaptive, 【divergences here might be evidence of allopatric speciation in process.】 词汇： A glimpse of 看见，瞥见 Mutation 突变，变种 Divergence 变化，变异 Allopatric speciation 异地物种形成 2. 理解大意 该句是由because引导的原因状语从句和方括号内的主句组成的嵌套句，从句的主谓宾已用绿色字体标出，大意为：因为G的研究让人们看到了突变的逐渐 1

2020年托福阅读模拟试题及答案(卷九)

2020年托福阅读模拟试题及答案（卷九） 托福阅读文本： The Native American peoples of the north Pacific Coast created a highly complex maritime culture as they invented modes of production unique to their special environment. In addition to their sophisticated technical culture, they also attained one of the most complex social organizations of any nonagricultural people in the world. In a division of labor similar to that of the hunting peoples in the interior and among foraging peoples throughout the world, the men did most of the fishing, and the women processed the catch. Women also specialized in the gathering of the abundant shellfish that lived closer to shore. They collected oysters, crabs, sea urchins, mussels, abalone, and clams, which they could gather while remaining close to their children. The maritime life harvested by the women not only provided food, but also supplied more of the raw materials for making tools than did fish gathered by the men. Of particular importance for the native tool kit before the introduction of metal was the wide knife made from the larger mussel shells, and a variety of cutting edges that could be made from other marine shells. The women used their tools to process all of the fish and marine mammals brought in by the men. They cleaned the fish, and dried vast quantities of them for the winter. They sun-dried fish when practical, but

新托福阅读之文本插入题解析 朗阁海外考试研究中心 南昌朗阁英语培训中心 文本插入题（Insert Text Questions）是新托福每次必考题型，每次题量不是很多，通常每篇文章0-1个左右。 问题形式： 在这类问题中，题目中给出一个新的句子，然后要求考生们利用文章的逻辑和句子之间的语法联系（比如代词的指代）来确定此句子在文章中最合适的位置。 注意：在文章中会出现四个黑色的方块，这些方块分布在句首或句末。四个方块有时都出现在一个段落中，有时分布在一段的末尾和下一段的开头。 Look at the four squares (■) that indicate where the following sentences could be added to the passage. （考生会看到一个黑体的句子） Where would the sentence best fit? 考生要做的是点击其中的一个方块，将这个句子插入文章。 解题步骤： 1. 读被插入的句子，找出句首或句尾的关键词或关键意思 2. 阅读可以插入方块前后的信息，寻找与插入句相关的意思 3. 选择与插入句最相关的方块 注意：如果出现以下情况，答案都可能是错误的：

★打乱了相邻句子之间的逻辑性 ★影响了转折语的正确使用 ★打乱了代词与其指代对象之间的逻辑关系 ★隔开了本是相邻的两句话 解题技巧： 1. 利用一些过渡词（如某些逻辑关系词或短语等）帮助确定插入句子的位置，或者帮助确定排除不适合的位置。 Much of the water in a sample of water-saturated sediment or rock will drain from it if the sample is put in a suitable dry place.█But some will remain, clinging to all solid surfaces.█It is held there by the force of surface tension without which water would drain instantly from any wet surface, leaving it totally dry.█ The total volume of water in the saturated sample must therefore be thought of as consisting of water that can, and water that cannot, drain away.█ Look at the four squares [█] that indicate where the following sentence could be added to the passage. What, then, determines what proportion of the water stays and what proportion drains away? Where would the sentence best fit? Click on a square to add the sentence to the passage. 技巧分析：首先读被插入的句子，它能给出的线索就是，该句子后面的信息应该是讲述“决定流干的水和不能流干的水的含量的因素”。读文中四个方块前后的信息，第一个方块前面的句子和后面的句子用关系逻辑词“but”连接，形成转折关系，不可插入其他内容；第二个方块后面的句子中出现“it”, 指代方块前面句子中的“some”, 插入其他内容会导致指代混乱，因此不可插入句子；第三个方块前后的信息用逻辑关系词“therefore”衔接，形成因果关系，也不可以插入其他内容，因此我们可以把被插入句子放在第四个方块那儿。如果考生们不确定，可以进一步读下一段中第一句

A.Surface tension is not strong enough to retain drops of water in rocks with large pores but it strong enough to hold on to thin films of water in rocks with small pores. B.Water in rocks is held in place by large pores and drains away from small size pores through surface tension. C.Small pores and large pores both interact with surface tension to determine whether a rock will hold water as heavy drops or as a thin film. D.If the force of surface tension is too weak to hold water in place as heavy drops, the water will continue to be held firmly in place as a thin film when large pores exist. 解题： 1看原句是否有逻辑关系，初步浏览了一下，看到了but这个表转折的连接词，这是一个有逻辑关系的句子。 2 看选项，找到表转折的连接词，只有A选项符合。 原句的大意是： 如果孔很大，那么里面的水就大如水滴，表面的张力不能将其托住，里面的水很快就会流尽;但是如果孔足够小，孔里的水

2019托福阅读：模拟试题及答案解析（6） 【托福】 Although only 1 person in 20 in the Colonial period lived in a city, the cities had a disproportionate influence on the development of North America. They were at the cutting edge of social change. It was in the cities that the elements that can be associated with modern capitalism first appeared — the use of money and commercial paper in place of barter, open competition in place of social deference and hierarchy, with an attendant rise in social disorder, and the appearance of factories using coat or water power in place of independent craftspeople working with hand tools. "The cities predicted the future," wrote historian Gary. B. Nash, "even though they were but overgrown villages compared to the great urban centers of Europe, the Middle East and China." Except for Boston, whose population stabilized at about 16,000 in 1760, cities grew by exponential leaps through the eighteenth century. In the fifteen years prior to the outbreak of the War for independence in 1775, more than 200,000 immigrants arrived on North American shores. This meant that a population the size of Boston was arriving every year, and most of it flowed into the port cities in the Northeast. Philadelphia's population nearly doubted in those years, reaching about 30,000 in 1774, New York grew at almost the same rate, reaching about 25,000 by 1775. The quality of the hinterland dictated the pace of growth of the cities. The land surrounding Boston had always been poor farm country, and by the mid-eighteenth century it
