篇1：IBT阅读中插入句子题的解决技巧
IBT阅读中插入句子题的解决技巧
插入句子题是IBT阅读中的新题性。这类题目是给出一句话让我们来判断这句话应加入一个段落中四个方块的哪个部分，用鼠标双击所选的黑色方块即可。做这类题目的关键首先是理解该句子，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。
掌握衔接词是解答插入句子题的关键
掌握衔接词对解答这类问题非常重要，因为它是理解上下文和这个句子的逻辑关系的核心。衔接词语主要包括代词（指示代词，例如this, these their, it, such, another ,这些通常是上文提到过的，所以可以采用就近原则来做。）；关键同义词，重复出现的形容词，副词和名词；表示因果，转折等关系的过渡词语：如，therefore, so, however, as a result, consequently, on the contrary, however 等；递进扩展词：如，furthermore, also, as well, too, in addition, moreover, besides, even, additionally等；结构配对词：如，on the one hand…. on the other hand，some…others，同时还要注意一些表示顺序的词，如first ,second ,third等。
我们来具体来一个例子：
1. But there is also another special kind of conversational flow among Southern women that contributed to their writing. 2. Some of their talk took the form of tales and vignettes told for their own sake.3. Sometimes humorous, sometimes sad; all were as bright as the figures in the fine needle point. 4.
Look at the four positions that indicate where the following sentences can be added to the …paragraph of the passage.
These tales included grotesque, comic, and poetic descriptions, character sketches, narratives, gusts of feeling, delicate ironies, and astute observations.
Click on a position to add the sentence to the passage.
A: position 1 B: Position 2 C: Position 3 D: Position 4
具体的解题步骤：
1. 理解要插入的'句子：These tales included grotesque, comic, and poetic descriptions, character sketches, and narratives, gusts of feeling, delicate ironies, and astute observations. 我们看这个句子是主、谓、宾结构，其中宾语为一些列的并列名词和短语。
2. 寻找衔接词：这个句子的衔接词为：These tales
3. 分析这个句子和上下文的关系：位置1 不可能，因为它后面的句子是一个主题型句子，即，提出论点，而我们要插入的句子为一个小点，属于论据。然后看位置2，这里出现了和我们要加入句子一样的信息点Some of their talk took the form of tales and vignettes told for their own sake。显然句子放在位置2是不行的；位置3后面的句子是对其前面句子for their own sake的进一步解释。所以最后只能是位置4了。
4. 把这个句带入各个位置。
5. 检查每个位置，位置4是最恰当的。
总之，把握这五大步骤是我们解决插入句子题的一个便利小窍门，具体的应用方法因人而议。理解需要插入句子的结构，找出衔接词是解题关键。同时要注意整个段落的结构以及上下文逻辑关系。

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 be seen 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 Cuvier made 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 virtually everywhere.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。所以我们需要去寻找原文段落中哪里出现了至少两个地质学家的发现，于是我们找到了如下的位置。
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 be seen 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 Cuvier made 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 virtually everywhere.It was actually a principle of floral succession as well, because plants showed the same transformation through time as did fauna.
所以我们可以判断这个句子最初应该放在红色句子之后，这是第三个黑盒子的位置。这时我们需要做最后的检查。那么我们如何在将句子插入问题的过程中对其进行测试呢?
当插入句子放在黑盒子位置时，我们可以注意插入句子和后面句子之间的含义和逻辑是否也是真的。我们的感叹句的意思是这些地质学家的发现激励了世界各地的人们检查当地的化石和岩石记录。我们的第三个黑匣子背后的句子是人们很快发现，这种动物进化论不仅建立在英国和法国(前面提到过)，而且几乎遍布世界各地。因此我们可以发现，在我们的句子中提到的测试当地化石岩石的各个地方的人是最终结论的前提条件，也就是说，插入句必须出现在短语的前面，以便我们可以确定我们的题。您应该选择将其放在第三个黑框中。
通过这个典型的简单难度问题，我们对句子插入问题的测试点和解决问题的想法有所了解，因此我们会发现有时我们不需要完全理解每个单词，如果我们可以捕获如果使用关键字判断它与前一句之间的逻辑关系，然后我们也可以知道它的位置。
当然，引用逻辑只是可以在句子插入问题中采用的几种逻辑关系之一。我希望我们将有机会继续了解有关此类主题的更多信息。
托福阅读影响速度的因素
影响托福阅读速度的6大恶习：
1、逐字阅读 ---应该采用意群阅读法。
2、回读 ----阅读讲究一气呵成，不要遇到生词，难点就又从头读。容易割裂句子之间的语义关系。
3、指读。 用手，笔指着书一行行读。
4、出声阅读。
5、晃头读。
6、心译。
提高托福阅读速度的4大方法：
方法一：快速泛读(fastextensivereading)
这里讲的泛读是指广泛阅读大量涉及不同领域的文章，要求读得快，理解和掌握文中的主要内容就可以。要确定一个明确的阅读定额，定额要结合自己的实际，可多可少，例如每天读20页。
方法二：计时阅读(timedreading)
计时阅读每次进行5～10分钟即可，不宜太长。因为计时快速阅读，精力高度集中，时间一长，容易疲劳，精力分散反而乏味。
方法三：寻读(Scanning)
寻读又称查读，同略读一样，寻读也是一种快速阅读技巧。
寻读是一种从大量的资料中迅速查找某一项具体事实或某一项特定信息，如人物、事件、时间、地点、数字等，而对其它无关部分略去不读的快速阅读方法。
方法四：略读(skimming)
略读又称跳读(readingandskipping)或浏览(glancing)，是一种专门的，非常实用的快速阅读技能。
略读有下列几个特点：
A.以极快的速度阅读文章，寻找字面上或事实上的主要信息和少量的阐述信息。
B.可以跳过某个部分或某些部分不读。
C.理解水平可以稍低一些，但也不能太低。
另外，提醒大家，提高托福阅读速度的同时，考生还需要重视阅读段落中的开头句，结尾句和转折句。托福阅读中的段落都有严密的逻辑关系，读懂了这三个点，托福阅读段的大概意思就比较明确了。
托福阅读备考新手常见的4个问题答疑
1、托福阅读如何使用技巧?
参加托福考试的考试一般集中在高中生、大学生，词汇量在四五千左右，他们在接触托福阅读的时候会遇到很多生词，尤其是分门别类的学科词汇，分为地理、天文、生物学、动物学四大块，学员就会有很多的误解，到底应该掌握多少词汇才能做好托福阅读。其实只要确定好中心词汇和构架词汇的区别，对学科词汇只需要认知，对构架词汇需要熟知。在技巧中只需要通过分解句型，由于托福阅读特别长，每个都是长连句分析，把它按照逻辑分解之后，按照关键词，找到重点部分，最后找到简洁的出题主干，就很容易理解了。
2、读托福阅读文章应该使用哪种顺序方法?
读文章一般都是先看题目再读文章。看题目的话，托福和雅思的区别就在于要我们自己去定位，因为每个题目都是按照文章的顺序顺延下来的，只是在最后一个小结题目的时候需要翻开前面的文章，重点读每一段的首末句找到它。
3、托福阅读做题时有哪些常见误区?
大多数同学的问题都在于对句子的理解，尤其是复合句，考生无法理解整个句子，而是会按照个别的单次来分散，造成句子理解的中断。因此考生备考阅读时需要学会把句子分解，去看句子的构架，这样去找主干的话就会容易的多了。由于托福阅读中，一长段的内容实际上有效信息并不多，要从中找出有效信息就需要对句型有了解，只看独立的词就无法理解意思。
4、托福阅读词汇量过大学六级就能拿高分吗?
考生考过六级之后不一定能在托福上获得高分，六级和托福的考试还是有非常大的区别。六级的词汇量是考托福起码的一个基础。因为六级背诵的大多数是构架词汇，这些是需要熟练的。如果有六级词汇的基础，后续学习中基础提高也会比较快。
托福阅读快速提升技巧：速读和扫描
Skimming是只看主要大意的速读。一篇文章的大意是有重点的。比如，当出现first second的这种归类总结的地方，或because，as a result这样的因果关系，或是 but，however的语意转折处，都需要格外留心。托福文章讲述主要观点之后通常会有for example来佐证，如果看懂了主要观点，那么对示例所用的时间和精力就不需要太多了。Skimming的技巧在第一遍阅读文章意图抓住文章大意时是非常重要的。
托福的文章长度大多在300-400字之间。以平均每篇读10分钟计算，按照每分钟阅读150字的速度，一篇文章从头到尾通读，至少需2-3分钟。这 可了解文章的大意，但不一定保证读得透彻。在第一遍通读的过程中，考生不要期望每个字都一定要理解，遇到不懂的字不必多逗留或苦思冥想可能的意思，这样会 浪费时间的。只需一直往下看，用前面介绍到的skimming原则，掌握文章的主旨即可。这个过程中，文章的第一段，尤其是每段的第一句话往往起着提纲挈 领或起承转合的作用，是阅读时要多留心的地方。
Scanning是“扫描”，但具体到阅读中，大家最熟悉的莫过于查词典时。在有意识地去查某个生词的时候，我们不会去把它所在的页上每一个字都看一遍才找到想要的。几乎眼睛对词典中的一页扫一下，脑中只有要找的字，看到它，其他的地方都像没有看到一样。在托福的阅读中，scanning的技巧在回答问题时，根据题干中问到的内容，在文章中scan，可以帮助考生准确地定位，找到答案。
托福阅读备考之句子插入题答题技巧
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
(C) Methods ants use to identify food sources
(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
(C) delicate balance
(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.
(C) It informs workers of possible danger.
(D) It encourages the ants to gather together.
4. The word cluster in line 4 is closest in meaning to
(A) organ
(B) activity
(C) group
(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
(C) distinguish foreign ants from resident 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
(C) warn
(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.
(C) Pheromones control the speed at which ants move from one location to another.
(D) Pheromones enable scouts to identify suitable areas for establishing a new nest.

(B) appearing
(C) competing
(D) rushing
9. The word others in line 21 refers to

篇4：深入解析托福阅读句子插入题
深入解析托福阅读句子插入题
句子插入题是托福阅读十大题型之一，从句子层面考察考生对句间逻辑关系、段落大意的理解和把握。这类题目是给出一句话让我们来判断这句话应加入一个段落中四个方块的哪个部分,用鼠标双击所选的黑色方块即可。做这类题目的关键首先是理解该句子，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。
掌握衔接词对解答这类问题非常重要，因为它是理解上下文和这个句子的逻辑关系的核心。衔接词语主要包括代词(指示代词，例如this, these their, it, such, another ，这些通常是上文提到过的，所以可以采用就近原则来做。);关键同义词，重复出现的形容词，副词和名词;表示因果，转折等关系的过渡词语：如，therefore, so, however, as a result, consequently, on the contrary, however 等;递进扩展词：如，furthermore, also, as well, too, in addition, moreover, besides, even, additionally等;结构配对词：如，on the one hand…. on the other hand，some…others，同时还要注意一些表示顺序的词，如first ,second ,third等。
我们来具体来一个例子：1. But there is also another special kind of conversational flow among Southern women that contributed to their writing. 2. Some of their talk took the form of tales and vignettes told for their own sake.3. Sometimes humorous, sometimes sad; all were as bright as the figures in the fine needlepoint. 4.
Look at the four positions that indicate where the following sentences can be added to the …paragraph of the passage.
These tales included grotesque, comic, and poetic descriptions, character sketches, narratives, gusts of feeling, delicate ironies, and astute observations.
Click on a position to add the sentence to the passage.
A: position 1 B: Position 2 C: Position 3 D: Position 4
接下来再来看看如何解答这道题。理解要插入的句子，These tales included grotesque, comic, and poetic descriptions, character sketches, and narratives, gusts of feeling, delicate ironies, and astute observations. 我们看这个句子是主、谓、宾结构，其中宾语为一些列的并列名词和短语。寻找衔接词，这个句子的衔接词为：These tales。分析这个句子和上下文的关系：位置1 不可能，因为它后面的句子是一个主题型句子，即，提出论点，而我们要插入的句子为一个小点，属于论据。然后看位置2，这里出现了和我们要加入句子一样的信息点Some of their talk took the form of tales and vignettes told for their own sake。显然句子放在位置2是不行的;位置3后面的句子是对其前面句子for their own sake的进一步解释。所以最后只能是位置4了。把这个句带入各个位置。检查每个位置，位置4是最恰当的。
句子插入题的一个本质和一个原则往往被大家忽略，导致失分很多。一个本质---插入句是一句“可有可无”的话。题的出题位置大家比较清楚，一般处于倒数第二题的位置，并且用来出题的段落是大家应该在前面的题目中已经见到过，而之前的题目和文章既然大家理解起来没有出现大的障碍，就说明插入进来的句子是一句可有可无的话。这就要从两个方面来理解了。
何为“可有”?既然插入句能放进原文中去，就说明它和原文是有一定关系的，所以叫“可有”，这也就意味着，插入句的部分含义是在原文中有所重复的。所以我们的重点是回到文中找那部分被重复的句意。例如：
█Watt's steam engine soon showed what it could do. █It liberated industry fromdependence on running water. █The engine eliminated water in the mines by drivingefficient pumps, which m-ade possible deeper and deeper mining. █The ready availability ofcoal inspired William Murdoch during the 1790s to develop the first new form of nighttimeillumination to be discovered in a mill-ennium and a half. Coal gas rivaled smoky oil lamps andflickering candles, a-nd early in the new century, well-to-do Londoners grew accustomed togaslit houses and even streets. Iron manufacturers, which had starved for fuel while dependingon charcoal, also benefited from ever-increasing supplies of coal: b-last furnaces with steam-powered bellows turned out more iron and steel for the new machinery. Steam became themotive force of the Industrial Revolu-tion as coal and iron ore were the raw materials.
(官方真题Official6-Powering the Industrial Revolution)
Look at the four squares [█] that indicate where the following sentence coul-d be added tothe passage.
The factories did not have to go to the streams when power could come to th-e factories.
Where would the sentence best fit?
在上题中，“liberated industry from dependence on running water”和 “The factories did not have to go to the streams”句意便发生了重合。所以我们可以确定，文中第二句话的前后应该是我们可以选择的范围。
何为“可无”?这个便是经常被大家忽略的地方。既然这句话，可以省略，那么这个插入句究竟要符合什么特点呢?还是以上题为例，我们发现 “liberated industry from dependence on running water”和 “The factories didnot have to go to the streams”句意发生了重合，那究竟应该把插入句放在第二个█还是第三个█呢?这时就需要分情况讨论了：
情况1：放在第二个█，也就是说我们认为插入句是和下文有关系，既然要符合“可无”这个本质，所以说插入句必须是对下文概括或者引出。
情况2：放在第三个█，也就是说我们认为插入句是和上文有关系，既然要符合“可无”这个本质，所以说插入句必须是对上文进一步解释。
综合以上两种情况，我们会发现，插入句要么总结引出下文，要么进一步解释上文。所以我们会发现，在插入题中，前一句的叙述范围应该总比后一句大。 根据上述内容，也就引出了我们需要注意的一个非常重要的做题原则。
一个原则。在插入题中，句子的叙述顺序遵循从大到小，从抽象到具体的原则。找到重复的句意后，按照大小顺序安置插入句的位置。在上题中，“liberated industry from dependence on running water”的意思是解放了工厂对水流的依赖。 “The factories did not have to go to the streams”的意思是工厂不用去往河流的位置。显然前者说得更概括和抽象，后者更具体，所以按照从大到小的顺序，应该选择第二个█。
怎样Hold住托福阅读中的生词
在托福阅读中遇到生词，对理解无大碍者可一跃而过。只有难以推测的生词才借助词典。但过多依赖词典会打断托福阅读思路，影响速度及理解，这就需要学生会猜词。本文小编将告诉大家如何应对托福阅读生词。
可这不是说平时阅读一涉及到托福阅读生词便去猜测，如有条件使用词典，同学们还是应该将不会的生词一一查明，并加以记忆。只有这样才能扩充我们的词汇量，提高阅读理解能力。猜词可有多种方法，下面介绍几种常用且准确性高的方法，同样也适合在托福阅读考试中。
一、托福 阅读利用上下文线索猜测词义
1、根据同义、反义关系猜词
Today' s teenagers seem to be more liberal in their ideas than their _______ grandparents.
A. freethinking B. traditional C. old D. happy
traditional与liberal意思相反，故选B。
[推荐：英美主要报刊杂志资站大全篇]
2、根据句意或段落文章的上、下文猜测词义
Klebold and Harris felt _______ and wanted to revenge against those who disliked playing
together with them or laughed at them.
A. discouraged B. ashamed C. tired D. separated
根据下文的disliked playing together with them判断此处应为“感到孤立”，故选D。
托福阅读真题训练1
The most thoroughly studied cases of deception strategies employed by ground-nesting birds involve plovers, small birds that typically nest on beaches or in open fields, their nests merely scrapes in the sand or earth. Plovers also have an effective repertoire of tricks for distracting potential nest predators from their exposed and defenseless eggs or chicks.
The ever-watchful plover can detect a possible threat at a considerable distance. When she does, the nesting bird moves inconspicuously off the nest to a spot well away from eggs or chicks. At this point she may use one of several ploys. One technique involves first moving quietly toward an approaching animal and then setting off noisily through the grass or brush in a low, crouching run away from the nest, while emitting rodent like squeaks. The effect mimics a scurrying mouse or vole, and the behavior rivets the attention of the type of predators that would also be interested in eggs and chicks.
Another deception begins with quiet movement to an exposed and visible location well away from the nest. Once there, the bird pretends to incubate a brood. When the predator approaches, the parent flees, leaving the false nest to be searched. The direction in which the plover escapes is such that if the predator chooses to follow, it will be led still further away from the true nest.
The plover's most famous stratagem is the broken-wing display, actually a continuum of injury-mimicking behaviors spanning the range from slight disability to near-complete helplessness. One or both wings are held in an abnormal position, suggesting injury. The bird appears to be attempting escape along an irregular route that indicates panic. In the most extreme version of the display, the bird flaps one wing in an apparent attempt to take to the air, flops over helplessly, struggles back to its feet, runs away a short distance, seemingly attempts once more to take off, flops over again as the useless wing fails to provide any lift, and so on. Few predators fail to pursue such obviously vulnerable prey. Needless to say, each short run between flight attempts is directed away from the nest.

5. In the deception technique described in paragraph 2, the plover tries to
(A) stay close to her nest
(B) attract the predator's attention
(C) warn other plovers of danger
(D) frighten the approaching predator
6. The word spanning in line 19 is closest in meaning to

What unusual or unique biological trait led to the remarkable diversification and unchallenged success of the ants for ever 50 million years? The answer appears to be that they were the first group of predatory eusocial insects that both lived and foraged primarily in the soil and in rotting vegetation on the ground. Eusocial refers to a form of insect society characterized by specialization of tasks and cooperative care of the young; it is rare among insects. Richly organized colonies of the land made possible by eusociality enjoy several key advantages over solitary individuals.
Under most circumstances groups of workers are better able to forage for food and defend the nest, because they can switch from individual to group response and back again swiftly and according to need. When a food object or nest intruder is too large for one individual to handle, nestmates can be quickly assembled by alarm or recruitment signals. Equally important is the fact that the execution of multiple-step tasks is accomplished in a series-parallel sequence. That is, individual ants can specialize in particular steps, moving from one object (such as a larva to be fed) to another (a second larva to be fed). They do not need to carry each task to completion from start to finish — for example, to check the larva first, then collect the food, then feed the larva. Hence, if each link in the chain has many workers in attendance, a series directed at any particular object is less likely to fail. Moreover, ants specializing in particular labor categories typically constitute a caste specialized by age or body form or both. There has been some documentation of the superiority in performance and net energetic yield of various castes for their modal tasks, although careful experimental studies are still relatively few.
What makes ants unusual in the company of eusocial insects is the fact that they are the only eusocial predators (predators are animals that capture and feed on other animals) occupying the soil and ground litter. The eusocial termites live in the same places as ants and also have wingless workers, but they feed almost exclusively on dead vegetation.
