托福阅读句子插入题详细解析
托福阅读考试中的题型比较多，因此大家在复习的时候，难度也比较大。今天我们整理到的是关于句子插入题的解题方法，希望通过本篇文章的学习，帮助大家更好地理解这部分的内容。
句子插入题，也叫插入文本题，就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。
问题的形式是：
Look at the four squares [■] that indicate where the following sentence can be added to the passage.
[You will see a sentence in bold.]
Where would the sentence best fit?
Click on a square [■] to add the sentence to the passage.
做题步骤：
1)看选项，抓线索
先仔细阅读待插入的句子，弄清其含义，找出其中包含的衔接手段，根据词汇、逻辑、语法等衔接手段先对待插入句可能的前后句内容先做出适当预判。
2)观前后，找特征
看四个方块前后的句子，寻找其中的核心词，即如上述与待插入句子中的衔接手段相匹配的线索。
3)插句子，定答案
将句子插入到确定的位置，然后阅读上下句与插入句，从逻辑和语义上判断它和上下句之间是否连贯。
做题思路：
根据词汇、逻辑、语法等衔接手段可总结出四种最常见的做题思路，分别为：重复暗示、指代暗示、概述暗示和逻辑暗示。
即：拿到被插入句，先找出句中信息点所给的暗示，通常我们能找出上述四种中的至少一种暗示，然后根据这一种或多种暗示，判断前后句是否在逻辑和语义上都衔接恰当，选出答案。
下面来看例子。

▇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。
This economic reliance on livestock in certain regions makes large tracts of land susceptible to overgrazing。
Where would the sentence best fit?
我们先读给出的这句话--This economic reliance on livestock in certain regions makes large tracts of land susceptible to overgrazing. 这个句子使用的衔接手法(cohesive device)属于代词指代前文话题词。this后面的名词economic reliance on livestock一定在上一句里出现。于是，搜索段落，答案锁定在第二个方框前的那一句The raising of livestock is a major economic activity in semiarid lands, where grasses are general the dominant type of natural vegetation。这句话与被插入的句子话题一致，都是在讲"经济上依赖牲口"这件事，所以应插入第二个方框。

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。
