仔细阅读待插入的句子，找出其中包含的衔接手段，根据词汇、核心词、逻辑等衔接手段，对待插入句可能的前后句内容做出预判。
看四个方块前后的句子，寻找线索，即如上述与待插入句子中的衔接手段相匹配的线索。
将句子插入到确定的位置，阅读上下句与插入句，从逻辑和语义上判断句间是否连贯和衔接。
代词衔接，重复核心词和逻辑衔接。
代词衔接是句插题中最容易寻找的突破口。
代词，包括指示代词和人称代词。托福阅读中考察的待插句通常会以代词+名词的形式出现。
a.指示代词：this, these, it, such, another, that, these, those
b. 人称代词：he, she, one, they, his, her, one’s, their
c. 定冠词：the
d. such, either, same等
根据代词后指代前的思路，即后面的代词一定是指代前面提到的内容。我们只需要根据待插句中代词后的名词回到原文中找到原词或者其同义改写，将待插句插到该句的后面即可。
▇The raising of livestock is a major economic activity in semiarid lands, where grasses are general 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. ▇ Look at the four squares ▇ that indicate where the following sentence can be added to the passage。 Where would the sentence best fit? This economic reliance on livestock in certain regions makes large tracts of land susceptible to overgrazing.
根据 this 这个代词，我们找到线索：这种经济依赖（economic reliance），回到原文对应段落，我们会发现第一句中economic activity(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，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。另外，第二句中的an excessive number of livestock grazing又以核心词改写的方式重现了待插句中的overgrazing。通过以上的衔接，这三个句子在意思上实现了连贯。
核心衔接就是通过待插句子和方块附近的句子中的核心名词重复或者同义改写方式来实现句子间的连贯。我们首先需要根据待插句的核心词，找到原段中的重复或者改写词，然后用逻辑判断这两个句子的前后顺序。
Paragraph 3: Film analysis of the infant's responses, heart and respiration rate monitors, and non-nutritive sucking devices are used as effective tools in understanding infant perception.■Film analysis permits researchers to carefully study the infant's responses over and over and in slow motion. ■Precise measurements can be made of the length and frequency of the infant's attention between two stimuli. ■Heart and respiration monitors provide the investigator with the number of heartbeats or breaths taken when a new stimulus is presented. ■Numerical increases are used as quantifiable indicators of heightened interest in the new stimulus. Increases in non-nutritive sucking were first used as an assessment measure by researchers in1969
Look at the four squares [■] that indicate where the following sentence could be added to the passage.
The repetition allows researchers to observe the infant's behavior until they reach agreement about the presence and the degree of the infant's response.
Where would the sentence best fit?
解析：分析待插入的句子，我们找到核心词the repetition, 根据规则，前文中应出现repetition这个词或者其同义替换，从第一个小黑方块前一句开始分析，发现第二个黑方块前面出现了…over and over and in slow motion, 识别出是repetition的同义改写，则答案即为第二个小黑方块位置B。
大家平时读待插句时，一定要多思考逻辑关系，根据逻辑关系预测该句前后可能提到的内容。比如，给出的待插入句子是个例子，那我们应该将其放在相关的分论点之后。
逻辑衔接关键词：
A. 因果: because, therefore, thus, consequently, so, as a result
B. 对比: however, on the contrary, nevertheless, unlike, in contrast, while, although, but
C. 递进: furthermore, also, as well, too, other, in addition, moreover, besides, even, additionally
D. 顺序: for one thing…for another, then, finally
E. 举例：for example， a case in point, to illustrate
Paragraph 6: ■Because they are always swimming, tunas simply have to open their mouths and water is forced in and over their gills. ■Accordingly, they have lost most of the 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 keep from sinking, since most have largely or completely lost the swim bladder, the gas-filled sac that helps most other fish remain buoyant. Look at the four squares [■l that indicate where the following sentence can be added to the passage. Consequently, tunas do not need to suck in water. Where would the sentence best fit?
先看待插入的句子，Consequently这个单词表结果。按照逻辑词的逻辑关系，先排除第一个空，因为上段中并没有表述问题的原因。然后看到第一句有because，认为第二个空可能对。再往后看，发现第二，第四空之后都有they，排除了选第三个，根据前后句逻辑关系，选择B。意思是：因为金枪鱼的经常游动，它们必须张着嘴使水流经它们的腮。因此，它们不需要吸水。
因此，句子插入题的做法是借助代词，核心词和逻辑词，实现逻辑和语义的衔接。如果不确定，可以使用排除法一一排除不合适的选项，即前后两句话联系紧密不能插入句子，直到选出适合的选项。
