托福阅读插入问题答题分析

　　句子插入问题最初属于10种托福阅读问题中相对简单的类型，但许多学生会因为缺乏对问题类型的理解和忽视句子插入问题的本质和原则而失去很多分数。今天新航道沈阳托福培训的小编给大家简单介绍一下！

　　托福阅读语句插入题实质：插入句“无关紧要”

　　问题的位置我们很清楚，一般在倒数第二个问题的位置，用于问题段落是我们应该看到之前的主题，在主题和文章之前，因为我们理解没有大障碍，这意味着插入句子是一个无关紧要的词。这需要从两个方面来理解。

　　什么是“会有”？

　　由于插入句可以放入文本中，这意味着它与原文有一定的关系，所以它被称为“会有”，这意味着插入句的部分含义是在文本中重复的。所以我们的关键是回到文本中找到重复句子的意思。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?

　　在上述问题中，“liberated industry from dependence on running water”和“The factories did not have to go to the streams“句子的意思是重叠的。所以我们可以肯定，文中第二句的前后应该是我们可以选择的范围。

　　什么是“可无”？

　　这是一个经常被忽视的地方。既然这句话可以省略，那么这个插入句应该具备哪些特点呢？或者以上名为例，我们发现“liberated industry from dependence on running water”和“The factories didnot have to go to the streams“句子的意思是重叠的，那么应该把插入的句子放到第二个还是第三个呢？这时就需要分情况讨论了:

　　状况1：第二，也就是说，我们认为插入句与下面有关。既然要符合“可无”的本质，插入句必须总结或引出下面的句子。

　　状况2：第三，也就是说，我们认为插入句与上述有关。既然要符合“可无”的本质，插入句必须进一步解释上述内容。

　　基于以上两种情况，我们会发现插入句要么总结引出以下内容，要么进一步解释上述内容。因此，我们会发现，在插入题中，前一句的叙述范围应该比后一句大。

　　根据以上内容，也引出了我们需要注意的一个非常重要的原则：

　　托福阅读语句插入原则介绍

　　在插入问题中，句子的叙述顺序遵循从大到小、从抽象到具体的原则。找到重复句子的意思后，按大小顺序放置插入句子的位置。

　　在上述问题中，“liberated industry from dependence on running water“这意味着解放工厂对水流的依赖。”The factories did not have to go to the streams“这意味着工厂不必去河流的位置。显然，前者更具归纳性和抽象性，后者更具体，所以根据从大到小的顺序，选择第二个。

One of the most far-reaching e-xamples is the impact of thefine ninth-century AD. Chinese porcelain ware-s imported into the Arab world.
