成都雷哥网托福之TOEFL十大题型之句子插入题
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.Where would the sentence best fit?分析：本题待插入句中含有明显的指代词This，并有伴随有名词词组new form of manufacturing，这样可以推断出This指代的内容则为”new form of manufacturing”。
托福培训丨托福阅读句子插入题解题要点
托福培训丨托福阅读句子插入题解题要点朗阁托福培训中心孙亚楠句子插入题是托福阅读中的一道必考题型，题量不多，每篇文章中出现一道。
句子插入题是给出一句话让我们来判断这句话应该加入1-2个段落中的四个黑方块的哪个部分，用鼠标点击所选的黑色方块即可。
做这类题目的关键首先是理解待插入的句子，寻找其中的衔接词，分析这个句子的特点和其在文中的作用，然后把这个句子带入原文中检验其是否合适。
下面朗阁托福培训中心的专家将就句子插入题的解题步骤做出详细的说明。
解题步骤与解题要点阅读并分析待插入的句子，找出其中的线索词；从第一个小黑方块前一句开始读，逐一代入进行验证；插入句必须满足前后两条线索，先前再后。
（先用前线索再看后线索）从此步骤中可以看出掌握线索词是解答此题的关键，那么线索词都有哪些？主要有两大类，指代线索和逻辑线索。
1. 指代线索(1). 指代词(they, it, them)必然有所指代；指代词(this, these, their, other, another, such)后面若有名词短语，则向前寻找此名词短语或其同义改写。
例题1:Paragraph 4: Regularly flowing rivers and streams that originate within arid lands are known as "endogenous." These are generally fed by groundwater springs, and many issue from limestone massifs, such as the Atlas Mountains in Morocco. Basaltic rocks also support springs, notably at the Jabal Al-Arab on the Jordan-Syria border. ■Endogenous rivers often do not reach the sea but drain into inland basins, where the water evaporates or is lost in the ground.■Most desert streambeds are normally dry, but they occasionally receive large flows of water and sediment.■Paragraph 5: Deserts contain large amounts of groundwater when compared to the amounts they hold in surface stores such as lakes and rivers. ■But only a small fraction of groundwater enters the hydrological cycle—feeding the flows of streams, maintaining lake levels, and being recharged (or refilled) through surface flows and rainwater. (TPO 16 Water in the Desert)12. Look at the four squares [■] that indicate where the following sentence could be added to the passage.These sudden floods provide important water supplies but can also be highly destructive.Where would the sentence best fit?解析：1. 分析黑体句，找到其中的线索词即为these sudden floods, 则要插入的方块前面必定要出现名词短语sudden floods或是其同义改写。

解决托福大难题中的句子插入题
解决托福大难题中的句子插入题很多考生都习惯把学习重点放在发现和研究各类备考资料、解题技巧和高分经验上，而对于托福考试基础的题型研究却有所忽视。
今天给大家带来了解决托福大难题中的句子插入题，希望能够帮助到大家，下面就和大家分享，来欣赏一下吧解决托福大难题中的句子插入题什么是句子插入题?在一个段落中，句子与句子间不是毫无关联的，而是通过一定的衔接手段联系起来，来实现整个段落内容上的统一和连贯。
而我们要做的就是通过寻找原文方块前后句子中和待插句中的衔接手段，通过这些衔接线索，确定待插句最好的位置。
如何解决句子插入题?句子间的衔接手段通常有以下三种：代词衔接代词衔接是句插题中最容易寻找的突破口。
代词衔接包括句子中出现的人称代词he, she, they, his, her, their和指示代词this, it, these, such等。
福阅读中考察的待插句通常会以代词+名词的形式出现。
代词通常指代前一句中提到过的东西。
按照这个思路，我们只需要根据待插句中代词后的名词回到原文中找到一样的名词或者该名词的同义改写，将待插句插到该句的后面即可。
举个例子：This economic reliance on livestock in certain regions makes large tracts of land susceptible to overgrazing.根据this后的名词短语economic reliance on livestock (对牲畜经济上的依赖)，回到原文对应段落，我们会发现段首第一句中就出现了相关内容the raising of livestock is a major economic activity(饲养牲畜是一个主要的经济活动)。
这两个短语构成了一个代词衔接。
所以，我们可以将待插句插到第一句后，即为第二个空处。
同时，当我们插入该空处通读这几句话后，我们会发现，第一句中的in semiarid lands和待插句中in certain regions构成呼应。
托福阅读烧脑题型句子插入题怎么做
托福阅读烧脑题型句子插入题怎么做托福阅读烧脑题型句子插入题怎么做?掌握方法就能轻松搞定。
今天给大家带来了托福阅读烧脑题型句子插入题怎么做,希望可以帮助到大家，下面就和大家分享，来欣赏一下吧。
托福阅读烧脑题型句子插入题怎么做?掌握方法就能轻松搞定托福阅读句子插入题常见错误原因分析1、验证时容易犯“只承上”或“只启下”的错误;2、不知道从插入句中提取什么线索;3、常规解法基本熟练，但不会灵活使用排除法。
托福阅读句子插入题包含逻辑线索一览句子插入题中所提取的线索基本有三种：1、并列或递进关系(如again/also/another等);2、指代关系(如this/that/the/such等);3、逻辑关系(如因果/转折等)提取线索的主要目的是预判上下文的内容/情感色彩等，给后面的验证过程提供参考信息。
托福阅读句子插入题解题排除法步骤讲解1、把插入句带入选项进行一一比对;2、看选项的前后两句是否本身已有联系，如果有便不能再插入一句把该联系断开。
“承上启下”是完美标准，但有些正确选项并不一定吻合既“承上”又“启下”的特点(比如段落最前的A或段落最后的D),所以考生在验证选项时需要“瞻前顾后”，能够衔接上文并同时引导下文的选项才是最佳选项。
托福阅读背景材料：美国城市-费城费城是美国第四大都市，随同岁月的飞逝，与工业化的进展，费城所拥有的历史性遗产，已逐渐褪色。
但是在十八世纪中叶，费城却是起草与通过独立宣言的地方。
而且，美利坚合众国宪法草案也在费城起草与答署。
贝茜·罗斯在这里升起了合众国国旗。
华盛顿以总统身分，在这里也流过了许多岁月。
这里乃是美利坚合众国的诞生地。
独立纪念馆IndependenceHall建立于1732年，原为州政府，后于1776年7月，在该处发表独立宣言。
其后，又在该处起草合众国宪法，从而诞生了美利坚合众国。
议事厅CongressHall与独立纪念馆连接的建筑物。
1790年到1800年为止，该处为联邦议事厅。
托福阅读句子插入题如何衔接
托福阅读句子插入题——如何做到无缝衔接朗阁海外考试研究中心郑虹句子插入题(Insert Text Questions)是托福阅读考试必考题型，出现在每一篇文章倒数第二题，大部分考生在做此题时遇到模棱两可的答案情况较多，容易选错。
朗阁海外考试研究中心的专家将针对这个问题，具体分析句子插入题的考试特点及解题技巧。
一、题型特点句子插入题顾名思义就是给一句新的句子，要求考生们把这个句子插入到相应的位置，指定位置是文章中四个黑色方块的地方。
这些方块分布在句首或句末，四个方框有时都出现在一个段落里，有时分布在一段的末尾和下一段的开头。
考题形式如下：Look at the four squares [■] that indicate where the following sentence could beadded to the passage.[…………………］Where would the sentence best fit?同学们要做的是点击其中的一个方块并将这个句子插入文章。
句子插入题考查的内容是句子与句子间的逻辑关系，即所插入句子必须和前后句子在逻辑关系上保持一致。
其实和我们写作一样，同学们不能把两句毫无关系的句子放在一起。
那么在英语里为了体现句与句之间的逻辑关系，会采用各种衔接手段将句子连接起来，所以我们只要熟悉各种句子衔接手段，我们就能立即判断出来句子所插入的相应位置。
以下，我们将对考试中经常出现的几种衔接手段进行详细分析。
二、解题方法1. 词重复适用这种衔接方法简单粗暴明了，无需花费大量脑细胞，完全是送分题。
后面一个句子里重复使用前面句子提到的同一个词（通常是名词），使用此方法，我们可以清楚知道作者仍然在谈论同一主题，因为前后句子在意义上关系密切，互相连贯。
Their competition and collaboration were creating the broadcasting industryin the United States, beginning with the introduction of commercial radio programming in the early 1920s. ■With financial assets considerably greaterthan those in the motion picture industry, and perhaps a wider vision of the relationships among entertainment and communications media, they revitalizedresearch into recording sound for motion pictures. ■In 1929 the United States motion picture industry released more than 300 sound films—a rough figure, since a number were silent films with music tracks, or films prepared in dualversions, to take account of the many cinemas not yet wired for sound. ■At the production level, in the United States the conversion was virtually complete by1930. ■In Europe it took a little longer, mainly because there were more small producers for whom the costs of sound were prohibitive…Look at the four squares [■] that indicate where the following sentence could beadded to the passage.When this research resulted in the development of vastly improved sound techniques, film studios became convinced of the importance ofconverting to sound.前面一句话已经提及到了research, 第二次出现用this research, 所以答案选第二个选项。
托福阅读难点易错题型解题思路实例解析之句子插入题
托福阅读难点易错题型解题思路实例解析之句子插入题托福阅读不同题型在解题思路上是有很大区别的，今天我给大家带来了托福阅读难点易错题型解题思路实例解析之句子插入题。
希望能够帮助到大家，下面我就和大家分享，来欣赏一下吧。
托福阅读难点易错题型解题思路实例解析：句子插入题托福阅读句子插入题解题基本思路介绍在做题的时候，我们需要先读句子插入题中出现的句子，再看原文。
这样做的好处是比较省时间，可以较快的找到被插入句子的主语。
而且重点把握该句的动词和名词，从而为读原文做好准备。
托福阅读句子插入题解题思路实例分析举个例子，比如TPO34中Passage 3 Protection of Plants by Insects里的第13题：Look at the four squares [] that indicate where the following sentence could be added to the passage.Sometimes they capture the insects to feed their protein-hungry larvae.Where does the sentence best fit?通过这句话，我们可以发现they是该句的主语，动词capture 是谓语，而insects是句子中的宾语，那么抓住这个句子的主干再去做题，就明确了回原文阅读的目的了。
下面我们来看原文：Ants are probably the most frequent and certainly the most persistent defenders of plants.[A] Since the highly active worker ants require a great deal of energy, plants exploit this need by providing extrafloral nectar that supplies ants with abundant energy.[B]To return this favor, ants guard the nectaries, driving away or killing intruding insects that might compete with ants for nectar.[C]Many of these intruders are herbivorous and would eat the leaves of the plants.[D] 此时我们需要注意的，将句子插入原文后，插入后的句子不能改变原文间的内在逻辑关系。
托福阅读句子插入题解题技巧
托福阅读句子插入题解题技巧托福阅读考试中有10大类题型，针对这个题型的多样性，考生在备考托福阅读考试的时候就要对每一种题型进行总结。
这里小编为大家整理了托福阅读句子插入题的解题方法，希望对大家轻松应对托福阅读考试。
这里有8个解题步骤，大家一起来学习一下吧。
托福阅读句子插入题解题策略1、如果是段落之前的空，那么错误率高达百分之九十九，因为每个段的第一句往往是段落的中心句，如果把第一句内容改变了，同样也是改变了整个句子甚至段落的意思。
但两段式的插入句子。
第二个段落前面或者第一个段落后面的空格往往最容易是正确的。
2、空格后面出现代词"this, these, that, those, he, she,they, it, such, each, other, one, another, both, each,anybody, none, some, any"等，一般都是错的，因为代词不能跨距，如果在代词的前面加入了一句话，那么就会改变代词的指代对象。
但也并不绝对，如果概念只有一个主语，其他格局出现连续指代前句，就无法排除后又代词的选项，这就是例外情况。
3、被插入的句子中如果存在指代关系，如"this, these, that, those, he, she, they, it, such, each, other, one,another, both, each, anybody, none, some, any"等，建议不选择整段最前面的空格，主要是因为插入句本身无足轻重的地位，一般不会考察段落之间的承接关系。
但要明确一点，两段式插入句子除外。
4、正确的答案优先考虑段落最后的空，并不是最后一个空格，而是空格在段落的最后。
因为是放在段尾的，本身对文章没有过多的印象，所以优先考虑。
5、如果空格后出现时间点，而句子又不是在强调某件事，所以一般不建议选择，时间一般和前句所发生的时间衔接较为紧密，不可拆分。
toefl阅读句子插入题
toefl阅读句子插入题托福阅读部分中的句子插入题相对于词汇题、句子简化题、事实信息题，它在每篇文章都会出现一道题，而且位置是固定的，一定在最后一题内容小结题之前的倒数第二题，如此一来若是答错了也不影响考生对文章的理解和做题。
那么如何应对该类考题呢?店铺接下来就跟大家分享toefl阅读句子插入题的解法。
既然这句插入的话对文章本身是没有影响的，那么插入的句子插在某段段首的几率大么?答案明显是否定的。
原因呢?因为外国人的思维模式比较直截了当，不会像中国人那样藏着掖着，抛砖引玉或是画龙点睛。
所以往往在某段第一句的句子在该段都起着至关重要的角色：主题句，它会总结上文，而更多的情况是引领下文。
我们排除了一个答案：就是段首的位置，但是还有三个干扰选项啊句子插入题到底在考察什么呢?答案是：上下文的衔接。
插入的句子一定要和上下文衔接得当。
下面环球托福老师就带广大的托儿们了解句子插入题解题方法。
步骤一：先阅读要插入的句子。
步骤二：关注插入的句子主语部分，要在该插入句子之前得以重复。
以TPO4 Deer Population of the Puget Sound的句子插入题为例。
Paragraph 2-3: Nearly any kind of plant of the forest understory can be part of a deer'sdiet, where the forest inhibits the growth of grass and other meadow plants,the black-tailed deer browses on huckleberry, salad, dogwood, and almost any other shrubor herb. But this is fair-weather feeding. What keeps the black-tailed deer alive in the harsher seasons of plant decay anddormancy? Onecompensation for not hibernating is the built-in urge to migrate. Deer may move from high-elevation browse areas in summer down to the lowland areas in late fall.Even with snow on the ground, the high bushy understory is exposed;also snow and wind bring down leafy branches of cedar, hemlock, red alder,and other arboreal fodder.The numbers of deer have fluctuated markedly since the entry of Europeansinto Puget Sound country. The early explorers and settlers told of abundantdeer in the early 1800s and yet almost in the same breath bemoaned the lack ofthis succulent game animal.Look at the four squares [] that indicate where the following sentence couldbe added to the passage.There food is available and accessible throughout the winter.Where would the sentence best fit?插入的句子主语部分出现两个单词there 和food, there是地点状语，说明插入的位置之前出现了地点和食物。

托福阅读备考之句子插入题技巧
托福阅读备考之句子插入题技巧托福阅读备考之句子插入题答题技巧句子插入问题很多学生会花很长时间在这个话题上，或者花太多时间。
主要原因是每个人都没有想出这个主题背后的核心测试点。
如果每个人都关注的是使用这句话的意思来判断应该出现在原始段落中的正确位置，那么将会有一半的情况。
接下来，让我们讨论解决此类问题的重要思想。
在分析解决问题的思想之前，首先要明确的是，本课题着重于学生对句子与句子之间逻辑关系的掌握和判断。
所以这提醒我们的同学，除了注意这句话的意思之外，我们还试图判断这句话与其前后句子之间的逻辑关系，以帮助每个人确定正确的位置。
然后，在我们的句子插入问题中，将在测试中测试什么逻辑关系，这里是对其中一个的简单分析。
参考逻辑在我们的插入问题中，我们经常会遇到这种类型的句子。
在句子的前半部分，将出现代词+名词结构。
这意味着在前一句中提到代词后面的名词。
而且，我们所能做的就是回到最初的段落来找到该术语中出现的句子。
但是，这里需要强调的是，在原始段落中很难找到术语本身，因为一般来说，插入句子中代词之后的名词不会复制原始词，但会使用更一般性。
名词或同义词，所以我们在原始文本中寻找的是名词的特定内容。
找到包含这样一个词汇表的句子，那么你最初可以假设我们的插入应该放在它之后。
我们可以看一下典型参考逻辑的以下示例。
The findings of these geologists inspired others to examine the rock and fossil records in different parts of the world.Not only could Smith identify rock strata by the fossils they contained, he could also see a pattern emerging: certain fossils always appear in more ancient sediments, while others begin to beseen as the strata become more recent. By following the fossils. Smith was able to put all the strata of England's earth into relative temporal sequence. About the same time, Georges Cuviermade the same discovery while studying the rocks around Paris. Soon it was realized that this principle of faunal animal succession was valid not only in England or France but virtuallyeverywhere.It was actually a principle of floral succession as well, because plants showed the same transformation through time as did fauna.根据我们前面的分析我们在这句插入句中找到了两个代词后的名词，这意味着在这句话前面已经提到过了一些地质学家的发现，而且我们需要注意的是这两个名词都是复数。

成都雷哥网托福之TOEFL十大题型之句子插入题Insert Text question，属于托福阅读十大题型中难度比较大的一种。
除了需要对全文有良好的把握之外，有一定读懂长难句的能力。
句子插入题顾名思义就是给一句新的句子，要求考生们把这个句子插入指定位置，文章中四个黑色方块的地方。
这些方块分布在句首或句末，四个方框有时都出现在一个段落里，有时分布在一段的末尾和下一段的开头。
句子插入题考察的具体是什么内容呢？类似于写作，当我们把2个句子写在一起的时候，这个两个句子不可能没有任何关系，那么当我们做题时，决定在某2个句子之间插入一个新句子，很可能是应为觉得他们连接关系不精密，反之，当我们拒绝在某2个句子中插入第3个句子时，即认为这2个句子间的联系非常紧密，不需要再补充。
换言之，句子插入题需要我们判断句子与句子间的逻辑关系，插入的句子后必须和前后句子在逻辑关系上保持一致。
所以我们只要熟悉各种句子衔接手段，我们就能立即判断出来句子所插入的相应位置。
以下，我们将对考试中经常出现的几种衔接手段进行详细分析。
1.词指代同义替换1.Earth's internal heat,fueled by radioactivity,provides the energy for plate tectonics and continental drift,mountain building,and earthquakes.It can also be harnessed to drive electric generators and heat homes.Geothermal energy becomes available in a practical form when underground heat is transferred by water that is heated as it passes through a subsurface region of hot rocks(a heat reservoir)that may be hundreds or thousands of feet deep.■The water is usually naturally occurring groundwater that seeps down along fractures in the rock; less typically,the water is artificially introduced by being pumped down from the surface.■The water is brought to the surface,as a liquid or steam,throughholes drilled for the purpose.■By far the most abundant form of geothermal energy occurs at the relatively low temperatures of80°to180°centigrade.■Water circulated through heat reservoirs in this temperature range is able to extract enough heat to warm residential,commercial,and industrial spaces.More than20,000apartments in France are now heated by warm underground water drawn from a heat reservoir in a geologic structure near Paris called the Paris Basin.Iceland sits on a volcanic structure known as the Mid-Atlantic Ridge.Reykjavik,the capital of Iceland,is entirely heated by geothermal energy derived from volcanic heat.Look at the four squares[■]that indicate where the following sentence could be added to the passage.In either case,the heated water will usually be under considerable pressure, and so may have a temperature that is well above its sea--level boiling point of100°centigrade.找到过渡词either case，两种情况中的任何一种，当作者仍在谈论同一主题时，句子在意义上关系密切，一般会重复使用前面句子提到的同一个词(通常是名词)，或者使用代词替代，新句子说到两种情况中的任何一种，拿在本句之前的句子应该已经出现了两种情况。
Where would the sentence best fit?Click on a square to add the sentence to the passage.2.How did it come about that farming developed independently in a number of world centers(the Southeast Asian mainland,Southwest Asia,Central America,lowland and highland South America,and equatorial Africa)at more or less the same time?Agriculture developed slowly among populations that had an extensive knowledge of plants and animals.■Changing from hunting and gathering to agriculture had no immediate advantages.■To start with,it forced the population to abandon the nomad's life and became sedentary,todevelop methods of storage and,often,systems of irrigation.■While hunter-gatherers always had the option of moving elsewhere when the resources were exhausted,this became more difficult with farming.■Furthermore,as the archaeological record shows,the state of health of agriculturalists was worse than that of their contemporary hunter-gatherers.Look at the four squares[■]that indicate where the following sentence could be added to the passage.Because humans had built up this knowledge as hunter-gatherers,it is logical to conclude that over time they would have become extremely efficient.同上，找到过渡词this knowledge，出现指代词，重复指代上句出现的内容。
Where would the sentence best fit?Click on a square to add the sentence to the passage.2.连接词衔接4.Leatherbacks keep their body heat in three different ways.The first,and simplest,is size.The bigger the animal is,the lower its surface-to-volume ratio; for every ounce of body mass,there is proportionately less surface through which heat can escape.An adult leatherback is twice the size of the biggest cheloniid sea turtles and will therefore take longer to cool off.Maintaining a high body temperature through sheer bulk is called gigantothermy.■It works for elephants,for whales,and,perhaps,it worked for many of the larger dinosaurs.■It apparently works,in a smaller way,for some other sea turtles.■Large loggerhead and green turtles can maintain their body temperature at a degree or two above that of the surrounding water,and gigantothermy is probably the way they do it.■Muscular activity helps,too,and an actively swimming green turtle may be7°C(12.6°F)warmer than the waters it swims through.Look at the four squares[■]that indicate where the following sentence could be added to the passage.However,these animals have additional means of staying warm.找到过渡词However，在英语中，表达句与句之间的逻辑关系通常会用到连接词，常考连接词有表转折，原因，结果，递进等。
