1、托福阅读逻辑推理题3个高效解题思路实例精讲托福阅读 推理题需要针对性解题技巧来提升答题效率和正确率,那么这种考察思维能力的题型应该如何解答呢?今天给大家带来了托福阅读逻辑推理题3个高效解题思路实例精讲,希望能够帮助到大家在托福考试中拿高分，下面的书本网上资源非常多，大家只要百度书名.mobi就可以搜到Kindle上可以阅读的书本了。托福阅读：我们都是柯南，详解推断题推断题，顾名思义，就是要做一定的推理，于是，同学们沸腾了，推理啊!谁不会啊!毛利小五郎上身!神探夏洛克附体!我就是柯南!五花八门，无奇不有，无孔不入，似乎每个选项都很有道理!于是，陷入死循环，等到再遇到这样的题型，只能凭感觉，看到哪

2、个选项顺眼，就选择哪个选项。然后，你就错了。那么，今天我们从一个最简单的角度来攻破推断题，即反向推理。反向推理，指当事物A和事物B特征相反，现在已知事物A特征，问B特征时，那么B等于A的反向特征。而其中，最为明显的在于时间前后的推理。我们先看一道非常简单的真题。【Paragraph 1】The story of the westward movement of population in the United States is, in the main, the story of the expansion of American agricultureof the development

3、of new areas for the raising of livestock and the cultivation of wheat, corn, tobacco, and cotton. After 1815 improved transportation enabled more and more western farmers to escape a self-sufficient way of life and enter a national market economy. During periods when commodity prices were high, the

4、 rate of westward migration increased spectacularly. Old America seemed to be breaking up and moving westward, observed an English visitor in 1817,during the first great wave of migration. Emigration to the West reached a peak in the 1830 s. Whereas in 1810 only a seventh of the American people live

5、d west of the Appalachian Mountains, by 1840 more than a third lived there.1.What can be inferred from paragraph 1 about western farmers prior to 1815?A.They had limited their crop production to wheat, corn, tobacco, and cotton.B. They were able to sell their produce at high prices.C. They had not b

6、een successful in raising cattle.D. They did not operate in a national market economy.本题中有非常明显的信息可以帮助我们定位，即年份数字“1815”，定位到原文After 1815 improved transportation enabled more and more western farmers to escape a self-sufficient way of life and enter a national market economy. 在1815年之后，改进的交通方式使得越来越多的西部弄明

7、逃开了自给自足的生活方式，进入了国家市场经济。这是讲在1815年之后的事情，而题干中问的是“prior 1815”，即在1815年之前，那么根据反向推理原理，直接对1815年之后的事情取反，即“在1815年之前，交通方式还未改进，人们是自给自足的生活方式，还未进入国家市场经济”，直接对应D选项。所以本题选择D选项。在托福阅读考试当中，时间上的反向推理题还有很多很多，难度也可能会更高，比如，我们再来一道题。【Paragraph 1】It was not until the Cambrian period, beginning about 600 million years ago, that a

8、 great proliferation of macroscopic species occurred on Earth and produced a fossil record that allows us to track the rise and fall of biodiversity. Since the Cambrian period, biodiversity has generally risen, but there have been some notable exceptions. Biodiversity collapsed dramatically during a

9、t least five periods because of mass extinctions around the globe. The five major mass extinctions receive most of the attention, but they are only one end of a spectrum of extinction events. Collectively, more species went extinct during smaller events that were less dramatic but more frequent. The

10、 best known of the five major extinction events, the one that saw the demise of the dinosaurs, is the Cretaceous-Tertiary extinction.2. Paragraph 1 supports which of the following statements about life on Earth before the Cambrian period?A. Biodiversity levels were steady, as indicated by the fossil

11、 record.B. Levels of biodiversity could not be tracked.C. The most dramatic extinction episode occurred.D. Few microscopic species existed.本题中我们可以根据专业词汇“Cambrian period”定位到It was not until the Cambrian period, beginning about 600 million years ago, that a great proliferation of macroscopic species o

12、ccurred on Earth and produced a fossil record that allows us to track the rise and fall of biodiversity. 直到六亿年前的寒武纪时期，肉眼可见的生物才在地球上大量出现并产生可以让我们了解物种多样性兴衰的化石。可是题干中用的是“before the Cambrian period”，即寒武纪之前，那么只要将原文中寒武纪之后的内容取反，即“在寒武纪之前，肉眼可见的生物还没有大量出现，我们还不能了解物种的多样性”，对应B选项。所以，当问题或原句信息中出现了明确的在某种时间前后发生的事件时，大家要注意

13、作者已经在给出一定的提示了，我们可以通过前后的信息进行推断。从这个角度看来，其实，阅读的推断题，很可爱对吗?只要我们了解它的出题原理和作者的出题意图，明确原文中句子间的逻辑关系，其实推断题并不是为难广大考生的绊脚石，而是帮助我们取得阅读高分、提升阅读理解能力的好工具!考托福雅思GRE对不出国的人有什么意义 考托福和雅思仅仅是为了出国么?如果你这样想就大错特错了!今天小编给大家带来了考托福 雅思VS托福、GREVSGMAT究竟哪个更好考 雅思 VS 托福、GRE VS GMAT究竟哪个更好考?今天小编给大家带来了雅思 VS 托福、GRE VS 托福考试评分标准 认真了解这些托福评分标准，高效备考是王道!小编给大家带来了TOEFL托福阅读的评分标准 托福复考8月最新考点、考试日期全知道 托福复考!8月最新考点、考试日期全知道,今天小编给大家带来托福复考 ，希望能够帮助到 第 6 页 共 6 页
