一.题型特点
句子插入题也叫连贯性问题，检验的是考生将一句话插入到文章中最合适的位置的能力。这类题目的出题方式一般是Look at the four squares [█] that indicate where the following sentence could be added to the passage. Where would the sentence best fit?
二.解题方法
在做这类题目的时候，考生首要遵循以下步骤
1.分析要插入的句子。
因为我们要通过插入句寻找与上下文联系的纽带，通过逻辑纽带和语法纽带帮助自己答题。
①逻辑纽带
因果关系：because, consequently, as a result, accordingly;
并列：also, other, another, as well as;
转折：however，but, although
举例：for example, such as, including, for instance
②语法纽带
时态：插入句子的时态与前后文的时态要保持一致;
代词：插入句子的代词与其所指代的名词保持一致。
2.带着纽带回原文
3.代入原文检验
三.例题分析
1.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?
①分析要插入的句子
This economic reliance on(依赖) livestock(牲畜) in certain regions makes<隐含的因果关系> large tracts(大片土地) of land susceptible to(易受…影响的;对…敏感的)overgrazing(过度放牧).<结果>
②带着纽带回原文
This economic reliance on livestock
■The raising of livestock is a major economic activity(主要经济活动) in semiarid lands, where grasses arc generally the dominant type of natural vegetation.<定语从句> ■ 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.■
因为在句子中有所指代，前面应该有信息出现，所以第一个空那里是错误的。第三个空中已经说明了结果，所以放在第三个空汇总不合适。通过联系上下文我们会发现放在第二个空中是合适的。
2. 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?
①查看插入的这句话
This<表示指代关系>new form of manufacturing depended on<隐含的因果关系> the movement of goods to distant locations and a centralized source of laborers.
②带着纽带回原文
This new form of manufacturing
Before 1815 manufacturing in the United States had been done in homes or shops by skilled artisans. ■ As master croft 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(给…让路) 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.
第一个空之前的句子表达的是之前大部分都是在家中或者是手工作坊完成的，但是在这里并没有体现new，所以我们可以接着往下找，第二句说的是，师傅会将自己的工艺传授给土地。读到这个地方我们依然找不到相应的答案。第三句表达的是妇女也会在家做一些兼职工作。第四局表达是1815年之后，began to是一个动态的过程，而且结合需要插入句子的内容可以推测出，放在这个部分是正确的。
3. Look at the four squares [■] that indicate where the following sentence can be added to the passage. All three of them have strengths and weaknesses but none adequately answers all of the questions the paintings present. Where would the sentence best fit?
①查看插入的这句话
All three of them(指代) have strengths and weaknesses but (转折关系)none (指的是all three of them)adequately answers all of the questions the paintings present.
①查看插入的这句话
■Unfortunately, this explanation fails to explain the hidden locations, unless the migrations were celebrated with secret ceremonies. ■很多考生在看到all three of them的时候都会习惯性的从后面看起，但是从这个地方来看，这句话放在最后一个并不合适。
■ Because some paintings were made directly over others, obliterating them, it is probable that o painting's value ended with the migration it pictured. ■ Unfortunately, this explanation fails to explain the hidden locations, unless the migrations were celebrated with secret ceremonies.在这个过程中，我们并不能找到三种情况，所以也是不对的。
我们接着往前看，Scholars offer three related but different opinions about this puzzle.(在这里明确的指出了三种相关的理由，所以这句话填在这里是对的) ■ One opinion is that the paintings were a record of the seasonal migrations mode by herds. (在这里只是指出了一种，所以并不符合。)■ Because some paintings were made directly over others, obliterating them, it is probable that a painting's value ended with the migration it pictured.
从这个题目中考生应该注意，all three of them不一定是在作总结，也可能是在总起。
托福阅读考试中的句子插入题并不像考生想象的那么困难，所以小编建议考生在掌握以上技巧和方法的基础上，要学会利用历年真题进行练习，提升对于托福阅读解题技巧的使用能力，争取在考试中取得高分。
