托福阅读句子插入题本质：插入句“可有可无”
本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.
(托福官方真题6-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。
