托福阅读找逻辑提升词秒解句子插入题技巧实例精讲

托福阅读句子插入题简介

句子插入题是考察句子与句子关系的题目。句子之间连接常见的线索有四项：指代、连接性副词、句子打头的并列连词FANBOYS(for, and, nor, but, or, yet, so)，以及观点与事实。其中前三项是可见线索，最后一项是不可见线索。这里主要介绍连接性的副词。

实例讲解托福阅读插入题的逻辑关系词运用

Paragraph 1: The city of Teotihuacán, which lay about 50 kilometers northeast of modern-day Mexico City, began its growth by 200-100 B.C. At its height, between about A.D. 150 and 700, it probably had a population of more than 125,000 people and covered at least 20 square kilometers. A. █ It had over 2,000 apartment complexes, a great market, a large number of industrial workshops, an administrative center, a number of massive religious edifices, and a regular grid pattern of streets and buildings. B. █ Clearly, much planning and central control were involve d in the expansion and ordering of this great metropolis. C. █ Moreover, the city had economic and perhaps religious contacts with most parts of Mesoamerica (modern Central America and Mexico). D. █

In fact, artifacts and pottery from Teotihuacán have been discovered in sites as far away as the Mayan lowlands, the Guatemalan highlands, northern Mexico, and the Gulf Coast of Mexico.

我们要考虑什么地方能把两句话之间联系在一起。当你看到in fact的时候，大家来猜想句与句之间是什么逻辑关系呢?在英文中，in fact前后其实是并列、递进的关系，并不像我们中文中“事实上”是前后的转折。在托福阅读中，有in fact的地方，其实都是一个并列、递进的关系。

也就是，前后两句的意思基本上是取同的。如果你认为in fact的前后不一样，你会发现再也找不到答案了。这个真的不是开玩笑。在整个官方真题Official中我们能找到6、7道题由in fact开头的句子插入题。明确了句间的关系，我们进一步来看这句话具体的内容。它说，事实上来自Teotihuacán的陶器和工艺品能够在很远的地方被发现，然后是地点的举例。在阅读中，我们碰到并列的内容求同不求异，所以后面打包处理为很远的地方。

这些陶器和艺术品能够在别的地方被发现意味着什么呢?意味着它跟别的地方应该是有联系的。那么我们来一一判断每个空前有没有提到它跟别的地方是有联系的。

读完可以发现，A、B、C三个选项前面都没有讲到它跟别的地方的联系。再看D选项，它说这个城市或许有和中美洲的经济和宗教的联系，这里才出现联系。所以唯一能够跟前面匹配起来的就是D选项。前面说这个地方跟别地方有宗教和经济的联系，之后举个事实来支持它的工艺品能够在别的地方被发现，说明它果然有联系，所以用in fact来支持前面的观点。

在考虑句与句之间的关系的时候，一定要去注意这些表示句间逻辑关系的词，这些就体现了作者讲话的意图。

托福阅读材料练习：爱走神的孩子更聪明

Children whose minds wander might have sharper brains, research suggests.

A study has found that people who appear to be constantly distracted have more “working memory”, giving them the ability to hold a lot of information in their heads and manipulate it mentally.

Children at school need this type of memory on a daily basis for a variety of tasks, such as following teachers’ instructions or remembering dictated sentences.

During the study, volunteers were asked to perform one of two simple tasks during which researchers checked to ask if the participants’ minds were wandering.

At the end, participants measured their working memory capacity by their ability to remember a series of letters interspersed with simple maths questions.

Daniel Levinson, a psychologist at the University of Wisconsin-Madison in the United States, said that those with higher working memory capacity reported “more mind wandering during these simple tasks”, but their performance did not suffer.

The results, published online in the journal Psychological Science, appear to confirm previous research that found working memory allows humans to juggle multiple thoughts simultaneously.

Dr Jonathan Smallwood, of the Max Planck Institute for Human Cognitive and Brain Science in Leipzig, Germany, said: “What this study seems to suggest is that, when circumstances for the task aren’t very difficult, people who have additional working memory resources deploy them to think about things other than what they’re doing.”

Working memory capacity is also associated with general measures of intelligence, such as reading comprehension and IQ scores, and also offers a window into the widespread, but not well understood, realm of internally driven thoughts.

Dr Smallwood added: “Our results suggest the sorts of planning that people do quite often in daily life — when they are on the bus, when they are cycling to work, when they are in the shower — are probably supported by working memory.

“Their brains are trying to allocate resources to the most pressing problems.”

托福阅读材料练习：性格决定外表

If you exhibit positive traits such as honesty and helpfulness, the chances are that you will be perceived as a good looking person, for a new study has found that the perception of physical attractiveness is influenced by a person's personality.

The study, led by Gary W. Lewandowski, Jr, found that people who exhibit negative traits, such as unfairness and rudeness, appear to be less physically attractive to observers.

In the study, the participants viewed photographs of opposite-sex individuals and rated them for attractiveness before and after being provided with information on personality traits.

After personality information was received, participants also rated the desirability of each individual as a friend and as a dating partner.

Information on personality was found to significantly alter perceived desirability, showing that cognitive processes modify judgments of attractiveness.

“Perceiving a person as having a desirable personality makes the person more suitable in general as a close relationship partner of any kind,” said Lewandowski.

The findings show that a positive personality leads to greater desirability as a friend, which leads to greater desirability as a romantic partner and, ultimately, to being viewed as more physically attractive.

The findings remained consistent regardless of how “attractive” the individual was initially perceived to be, or of the participants' current relationship status or commitment level with a partner.

What would you think of this lady's physical attractiveness if she exhibited bad personal traits?

“This research provides a more positive alternative by reminding people that personality goes a long way toward determining your attractiveness; it can even change people's impressions of how good looking you are,” said Lewandowski.

托福阅读材料译文

如果你表现出诚实和乐于助人等美好品质，那么别人会觉得你的外表也很迷人。一项最新研究发现，一个人的性格会影响别人对他或她的外表吸引力的看法。

该项由盖里 W 勒万多维斯基负责的研究发现，人们认为，表现出不诚实和粗鲁等恶劣品质的人外表也不够吸引人。

研究对象首先观看了一组异性的照片，随后分别在得知照片中人物的性格特点之前和之后给他们的外表评分。

研究对象在得知照片中人物的性格特点后，还对与其中每个人交朋友或做恋人的期望值进行了评分。

研究人员发现，有关人物性格特点的信息大大改变了之前的喜好度评分，研究对象的认知过程改变了他们对照片中人物外表的评价。

勒万多维斯基说：“总的来说，如果人们认为一个人的性格较好，那么他们会觉得无论与这个人做朋友还是做恋人都更合适。”

研究结果表明，人们更期望与性格较好的人交朋友、成为恋人，从而会认为他们的外表更迷人。

无论照片中人物给人的“第一印象”怎样、或者研究对象目前的情感关系状况以及与伴侣的亲密程度如何，研究结果都是一致的。

托福阅读中的重要语法

一.级及绝对性词汇

文章中若出现 must ， all ， only ， anyone ， always ， never 等绝对性词汇或 first ， most beautiful 等级词汇，往往是考题要点，一般出“细节性题目”。这是因为它们都有一个共同的特点，那就是概念绝对，答案，无论是出题还是做题，不会产出歧义和疑问，因此很容易出题，答案绝对正确。

相反地，如果文章中出现相对性的词汇、例如 Some of the people chose red hats,some chose green hats,and others blue ones. 其中 some 为相对性词汇，如果我们出这样一道题： What color hats did some people choose? 那么就没有正确的答案，因为有可能为 red,green 或 blue ，给评卷带来困难。

二.同位语及插入语

文章中带有由 that is ，i.e. ，or 等词汇引导的名词词组，放在一个名词后面，为同位语;插入语是指副词、不定式、分词、从句等结构故在句首，句中或句尾，不做句子成分，但修饰整个句子、表达作者感情的语法结构。这些用逗号隔开的持殊结构往往也是考查的重点，一般会出“细节性题目”。

三.因果句

句中若有如下结构或词汇的称为因果句：

(1) 因果连词：because，since，for，as，therefore，so，consequently 等

(2)表示因果的动词：cause ，result in ，originate from 等;

(3) 表示因果的名词： base, basis, result,consequence 等，这些因果句都是指明某两个事件之间因果关系的，尤为出题者所青陈。因为通过出题可以考查文中两个事件内在的因果关系。此种句型一般出“推断性问题”。

四.段落句

文章各段第一句( 段首句 )和末段员后一句( 文尾句 )都是十分重要的地方，往往是文章作者表达中思想，进行总结综述的地方，因此常出(1)主题性问题，(2)细节性问题(3)结构性问题。

五.特殊标点

有一些特殊标点的含义也属于考查范围，它们是：

(1) 破折号，表示解释。考细节性问题;

(2) 括号，表示解释。考细节性问题;

(3) 冒号，一股同上，有时冒号也表示列举，则考“ EXCEPT ”题目;

(4) 引号。表示引用，考细节性问题：

(5) 惊叹号，表示作者感情，考态度性问题。

六.列举和并列句

列举指的是： First,... Second,... Third,...等逐条列出。并列句是指：A ，B and C，即逐项列出。它们共同的特征是列出二点或三点以上的条目。该类型语言点常考的题型是“细节性问题”，主要有两种：

1. Which 题型

该题型只要求从并列的三顶中选一项作为答案，其它条目与题目无关。在这种情况下，往往题目的答案出自最后一个选项。

2 . EXCEPT 题型

该题型俗称“三缺一”题型，即题目 4 个选项中有三个符合文章内容，剩下一个不符合，题目便是要求选出这个不符合文章内容的选项。例如： All of the following are mentioned as types of evidence concerning handedness EXCEPT ??? 这种题型只适合于考并列、列举句，这是因为它要求其三个选项一定是文章中出现的，也就是并列或列举之处。利用这一特点。我们在读文章的时候就可多留意，如看到并列、列举句，可预想其有可能被考到;如发现题目中有“三缺一”题型，则应到并列、列举处找答案。

七.否定及转折句

否定句是指带有 NO 或 NOT ， NEVER 等否定词的句子，而转折句则指带有 HOWEVER ， BUT 或RATHER 等关联词引导的句子，它们可以用下面的句型说明： A is not B ， as C ， but is D 。对于以上的句型常出“推断性问题”。

八.举例句

句中由 as 或 such as ， for example 等引导的短语或句子为举例句，常考“推断性问题”和“细节性问题”。上面句型中的 as C 为插入的举例句。

九.数字与年代

文中的数字、年代、日期等常常是出题者注意的考题点，如年 10 月第 48 题。

十.比较级及比喻

如果文中含有 more than 或 as... as ...，like ( a fly )等句型，则为比较级或比喻句结构，往往也是考题点，一般出“推断性题目”。

篇3：托福阅读句子插入题核心技巧解读

句子插入题解题核心就在于要把待插入句子放在方框内，使得它能和上下文衔接得当。如何做到上下文衔接得当?其一：句意。其二：逻辑。如果待插入句子中出现代词加名词短语，我们一定在原文中找到这个代词的指代;如果文中只有一处合适，答案就是那句话的后面;如果有两处以上符合，那么我们就观察一下这句话中有没有逻辑关系词，我们一定要确定这句话和上文逻辑关系正确。

托福阅读插入题实例介绍

Paragraph 6:■Because they are always swimming, tunas simply have to open their mouths andwater is forced in and over their gills. ■Accordingly, they have lost most ofthe muscles that other fishes use to suck in water and push it past the gills.■In fact, tunas must swim to breathe. ■They must also keep swimming to keepfrom sinking, since most have largely or completely lost the swim bladder, thegas-filled sac that helps most other fish remain buoyant.

Look at the foursquares [■] that indicate where the following sentence could be added to thepassage.

Consequently,tunas do not need to suck in water.

Where would the sentence best fit?

待插入句子中出现名词：tuna，我们不难发现，这段就是围绕tuna来写的，所以考虑逻辑关系词：consequently，表明上文提到了原因，下文应该是吞拿鱼不吸水的后果。我们在第二个方框后看到accordingly，这个词也是表示结果，后面说到“它们丢失了大部分用于吸水的肌肉”，所以这道题很好做了，逻辑简单，肯定是不吸水在先，然后才会丢失肌肉，所以答案是B。

托福阅读真题原题+题目

Tulips are Old World, rather than New World, plants, with the origins of the species lying in Central Asia. They became an integral part of the gardens of the Ottoman Empire from the sixteenth century onward, and, soon after, part of European life as well. Holland, in particular, became famous for its cultivation of the flower.

A tenuous line marked the advance of the tulip to the New World, where it was unknown in the wild. The first Dutch colonies in North America had been established in New Netherlands by the Dutch West India Company in 1624, and one individual who settled in New Amsterdam (today's Manhattan section of New York City) in 1642 described the flowers that bravely colonized the settlers' gardens. They were the same flowers seen in Dutch still-life paintings of the time: crown imperials, roses, carnations, and of course tulips. They flourished in Pennsylvania too, where in 1698 William Penn received a report of John Tateham's Great and Stately Palace, its garden full of tulips. By 1760, Boston newspapers were advertising 50 different kinds of mixed tulip roots. But the length of the journey between Europe and North America created many difficulties. Thomas Hancock, an English settler, wrote thanking his plant supplier for a gift of some tulip bulbs from England, but his letter the following year grumbled that they were all dead.

Tulips arrived in Holland, Michigan, with a later wave of early nineteenth-century Dutch immigrants who quickly colonized the plains of Michigan. Together with many other Dutch settlements, such as the one at Pella, Iowa, they established a regular demand for European plants. The demand was bravely met by a new kind of tulip entrepreneur, the traveling salesperson. One Dutchman, Hendrick van der Schoot, spent six months in 1849 traveling through the United States taking orders for tulip bulbs. While tulip bulbs were traveling from Europe to the United States to satisfy the nostalgic longings of homesick English and Dutch settlers, North American plants were traveling in the opposite direction. In England, the enthusiasm for American plants was one reason why tulips dropped out of fashion in the gardens of the rich and famous.

PASSAGE 85 CBADC CDCCB

托福阅读真题原题+题目

The smooth operation of an ant colony depends on ten to twenty different signals, most of which are pheromones (chemical signals triggering behavioral responses). It is estimated that red fire ants employ at least twelve different chemical signals. The simplest of these is the carbon dioxide from the respiration of an ant cluster, a chemical that acts as a pheromone to promote aggregation. Workers move toward a source of carbon dioxide, resulting in solitary ants moving to join a group. At the other extreme, the most complex of the fire ants' signals is probably colony odor, by which the workers of a particular colony or nest identify another worker as local or foreign. Each ant nest has its own odor as a result of its location, history, and local food supply. The resident ants pick up this odor on their bodies, so that ants of the same species, but from different nests, have different colony odors. This allows ants to identify intruders and maintain colony integrity.

Fire ants also make use of an alarm pheromone to alert workers to an emergency, and their scouts lay down a trail pheromone as a guide during mass migrations. A fire ant queen emits a chemical signal that identifies her to the colony's workers. They respond by scurrying to gather around her. The decomposing corpse of a dead ant also generates a signal, to which workers respond by eliminating the corpse from the nest.

Ants provide examples of both public (accessible to other species) and private messages. One of their most important private messages concerns food, for a food source is worth keeping secret. Each species marks its trails with signals that are meaningless to others, so that an ant crossing a trail left by another ant species typically notices nothing. On the other hand, a secret signal to mark a dead body is unnecessary. Many kinds of ants perceive a natural decomposition product of dead insects as a signal to remove a corpse. If an outsider recognizes this message and moves the body, no harm is done.

1. What aspect of ants does the passage mainly discuss?

(A) The relationship between the queen and the worker ants

(B) Ways in which ants use chemical signals

(D) The importance of respiration in the production of ant pheromones

2. The phrase smooth operation in line 1 is closest in meaning to

(A) daily activity

(B) effective functioning

(D) permanent location

3. According to the passage , carbon dioxide serves which of the following functions for fire ants?

(A) It protects the queen.

(B) It attracts other ant species.

(D) It encourages the ants to gather together.

4. The word cluster in line 4 is closest in meaning to

(A) organ

(B) activity

(D) cycle

5. According to the passage , each nest has a distinct odor that allows its inhabitants to

(A) find the location of the nest in the dark

(B) distinguish worker ants from other ants

(D) signal other inhabitants when foreign ants attack

6. The word alert in line 13 is closest in meaning to

(A) allow

(B) transport

(D) provide

7. What is the role of pheromones in the mass migrations of ants?

(A) Pheromones are used to create a trail that directs the ants during migrations.

(B) Pheromones signal the ants that the nest has been invaded and must be abandoned.

(D) Pheromones enable scouts to identify suitable areas for establishing a new nest.

8. The word scurrying in line 16 is closest in meaning to

(A) agreeing

(B) appearing

(D) rushing

9. The word others in line 21 refers to

(A) private messages

(B) species

(D) signals

10. Why does the author mention dead insects in line 23?

(A) To compare the social behaviors of ants with those of other insects

(B) To emphasize the dangers that all insects encounter

(D) To indicate a behavior that is common among various kinds of ants

11. Which of the following terms is defined in the passage ?

(A) pheromones (line 2)

Although指示转折关系，所以前、后半句是相反的含义，前面是limited，所以猜测词汇是limit负面的词，我们可以知道exact表示准确的意思，scarce是指稀有的，和limit属于类似的含义，initial开始的，词义不相干。所以选择C。

(1)Between 1900 and 1920 nearly 7.5 million new urban dwellings were added to aturn-of-the-century total of 10 million. (2)In the 1920s another 5.7 million were occupied. (3)Thus by 1930 a majority of urban homes had been built within the past thirty years.

托福阅读长难句解析：难点在于对地道表达和句间关系的理解。

第(1)句，从1900到1920，有7.5百万新住房被增入世纪之初(即1900年)的10百万总量住房中。

第(2)句，从1920-1929，另外的5.7百万新住房被居住。

第(3)句，因此，截止到1929，大多数的城市住房是在过去的30年(1900-1930)建的。为什么呢?因为7.5+5.7=13.2>10，已经超过1900前所有原住房数量了。即(7.5+5.7)/(7.5+5.7+10)>50%。

【待插入句子】One of the major effects was the rapid growth of the human population itself.

【待插入段落】Paragraph 1: The universal global warming at the end of the Ice Age had dramatic effects on temperate regions of Asia, Europe, and North America. Ice sheets retreated and sea levels rose. ■The climatic changes in southwestern Asia were more subtle, in that they involved shifts in mountain snow lines, rainfall patterns, and vegetation cover. ■However, these same cycles of change had momentous impacts on the sparse human populations of the region. ■At the end of the Ice Age, no more than a few thousand foragers lived along the eastern Mediterranean coast, in the Jordan and Euphrates valleys. Within 2,000 years, the human population of the region numbered in the tens of thousands, all as a result of village life and farming. ■Thanks to new environmental and archaeological discoveries, we now know something about this remarkable change in local life.

正确答案为3rd square;

2.插入句子说重大影响中的一个是：快速增长的人口。那么一定要跟在major effects后面，而我们看到了段落中的momentous impacts;完美的paraphrase，所以毫无疑问就是这里了。

再看段落，组成也很明确：1st为TS主旨句——全球变暖对于各洲的温带(temperate)区域有dramatic effcts。2nd: 西南亚的气候变化更细微。 3rd: 但是，同样的变化循环对人口稀少(sparse)的区域有巨大的影响。4th:在冰河世界末期，只有数千人。2000年间，人口成千上万的增长，都是因为乡村生活和农耕。5th：多亏了新发现，我们知道这种当地生活的剧烈变化。

【待插入句子】One example of such tropical abundance is found in Panama, which has 667 species of breeding birds一three times the number found in Alaska.

【待插入段落】 When we look at the way in which biodiversity (biological diversity) is distributed over the land surface of the planet, we find that it is far from even. The tropics contain many more species overall than an equivalent area at the higher latitudes. This seems to be true for many different groups of animals and plants. [■]

Why is it that higher latitudes have lower diversities than the tropics? [■] Perhaps it is simply a matter of land area. [■] The tropics contain a larger surface area of land than higher latitudes—a fact that is not always evident when we examine commonly used projections of Earth’s curved surface, since this tends to exaggerate the areas of land in the higher latitudes—and some biogeographers regard the differences in diversity as a reflection of this effect. [■] But an analysis of the data by biologist Klaus Rohde does not support this explanation. Although area may contribute to biodiversity, it is certainly not the whole story; otherwise, large landmasses would always be richer in species.

1.首先公布答案：1st square;

2.看到待插入句子中有one example…，这是个典型的论点+论据的结构! 给我们的是论据，那么前面一定要出现论点，这样才能和举例子对应起来。之后，看看举的是什么样的例子——这样的热带多样性被发现在Panama，有667个鸟类物种，是Alaska的三倍。

3.最后让我们来看一下待插入段落的各个句子：

P1:1st:当我们来看生物多样性(biodiversity)在地表分布的方式时，我们会发现这种分布(it)不是(far from)均匀的(even)。2nd:热带(tropics)比同样(equivalent)面积的高纬度(higher latitudes)地区包含了更多地物种。 3rd:这种现象对许多不同种类的动植物都是正确的。

P2: 1st: 为什么高纬度有(比热带)更低的多样性?

2nd: 可能只是陆地面积的缘故。(托福中经典的自问自答!)

3rd:热带(比高纬度区域)包含了更大的地表面积，有些生物地理学家把这种多样性的差异(differnece in diversity)当成是(regard...as)这种结果(this effect, 只带前半句的热带面积更大)的反射——面积的事实(a fact)在我们看地球曲面投影图的时候并不总是明显的，因为投影(this)会夸大(exaggerate)高纬度地区的陆地面积。(这一句也考到了句子简化题，注意”先大后小”的原则，破折号留到后面读)

4th: 但是KR的数据分析并不支持这个解释。

5th:尽管面积可能导致(contribute to…)生物多样性，它当然不是全部的理由(not the whole story);否则(otherwise),大的地表面积就应该总是有更丰富的物种。 (言外之意是并非如此。——考察常识)

看完之后就很清楚了，第一个段落讲现象，第二个段落讲原因。而待插入的句子说的是现象，所以放在第一段关于生物多样性的论点后面，perfect。

【待插入句子】 Indeed, at the height of Athenian democracy there was no government separate from its citizenry.

Where would the sentence best fit? Click on square [■] to add the sentence to the passage.

【待插入段落】 During the fifth century B. C. the council of 500 was extremely influential in shaping policy. [■] In the next century, however, it was the mature assembly that took on decision-making responsibility. [■] By any measure other than that of the aristocrats, who had been upstaged by the supposedly inferior “people,” the Athenian democracy was a stunning success. Never before, or since, have so many people been involved in the serious business of self-governance. [■] It was precisely this opportunity to participate in public life that provided a stimulus for the brilliant unfolding of classical Greek culture.[■]

1.首先公布答案：3rd square;

2.然后我们来看一下待插入的句子：Indeed表示强调，翻译成“确实”;at the height of… 在...的巅峰;还有一个there was no… 用否定来表示强调：没有政府是跟全体市民分隔开的，言外之意就是说雅典的民主程度非常之高。既然是强调，那前面一定要出现过相应的信息。

3.最后让我们来看一下这一段的各个句子：

1st: 议会(council)在制定(shape)政策上非常有影响力。 2nd: 但在下个世纪，成熟的立法机构(assemby)承担了做决定的职责。3rd: (以除了贵族之外的衡量标准看来，贵族被本应是下等人的人民抢去了风头)雅典的民主是一个巨大的成功. 4th: 空前绝后，从未有这么多人民参与到自我管理的严肃事业中来。 5th: 正是有了参与到公众生活的机会，才刺激了古典希腊文化的发展(unfolding,展开)。

看完之后就很清楚了，整个段落一句话总结——雅典民主很成功。1st承接上文;2nd～4th讲民主如何成功;5th讲民主带来的影响。而我们要插入的地方在民主程度高的后面，所以是在self-governance后面。放进去之后跟后面也能搭配起来，perfect.

知识小补丁

语法积累：

it was… that… 强调句的固定搭配;

other than… 表示否定，除了... 不是...

decision-making n+ v-ing; 理解的时候就按照v+n来理解，making decision;做决策。

never before, or since 前无古人，后无来者。
