托福备考经验：阅读推理题解题策略
1、一般对比推理：根据两个事情的对比特征，问其中一个事物的特征，只要将与之形成对比的另外一个事情的特征否定掉就可以。
2、时间对比推理：在这种推理中，一般有两个形成对比的时间段，它们所具有的特征一般相反。当题干问一个时间段的特征时，只要将与之相反的时间段的特征否定掉就可以了。
3、集合概念推理 ：一个大的集合的两个方面形成对比，两者之间存在着互补性关系，也就是一个的增加意味着另一个的减少。反之，相同。这个比较抽象，我们来看一个例子：
例如：Both the number and the percentage of people in the United States involved in nonagricultural pursuits expanded rapidly during the half century following the civil war, with some of the most dramatic increases occurring in the domains of transportation, manufacturing, and trade and distribution.
What can be inferred from the passage about the agricultural sector of the economy after the Civil War?
(A) New technological developments had little effect on farmers.
(B) The percentage of the total population working in agriculture declined.
(C) Many farms destroyed in the war were rebuilt after the war.
(D) Farmers achieved new prosperity because of better rural transportation.
文中指出：非农业人口的数量和比例都增加了。由此可知农业人口的数量和比例下降，所以(B)为正确答案。

托福阅读：浅谈推理题中的类比逻辑关系
很多同学最近一直和我抱怨，托福阅读中的推理题好难啊，很多题目的正确选项在文中都找不到，说好的忠于原文，说好的不用多想，不用为作者分忧解难呢?这时候我会偷笑，因为你们碰到的是细节题的升级版本—─推理题!我们平时在阅读教学中一直和同学强调，阅读要忠于原文，不要大开脑洞，所有答案均出现在原文中。唯独有一种题目即推理题，需要学生不仅在文中找到相关依据，还要根据这个依据走一步推理的过程，才能得出答案。
今天就想和大家分享一下阅读推理题中涉及到的一种逻辑推理关系 — 类比关系，此类逻辑关系一般出现在对比类的文段中。即文章中出现A,B两个比较对象， A与B有相同特征，于是我们可以根据A的特证来推断B也有相同的特征。举个例子：像小明一样，小红爱吃西瓜，于是乎我们可以从这句话里推断出不仅小红爱吃西瓜，小明也爱吃。接下去，我们就来看看这种逻辑关系在推理题中的应用。
Paragraph 1: When it comes to physiology, the leatherback turtle is, in some ways, more like a reptilian whale than a turtle. It swims farther into the cold of the northern and southern oceans than any other sea turtle, and it deals with the chilly waters in a way unique among reptiles.
What can be inferred about whales from paragraph 1?
A . They are considered by some to be reptiles.
B. Their bodies are built in a way that helps them manage extremely cold temperatures.
C .They are distantly related to leatherback turtles.
D .They can swim farther than leatherback turtles.
这道题目，题干问我们根据第二段的内容我们可以对鲸鱼作出何种推断，于是乎我们根据解题技巧快速回到文中搜索定位词whales, 找到以下这句话 ”the leatherback turtle is, in some ways, more like a reptilian whale than a turtle.” 这句话告诉我们leatherback turtle更像爬行的whales, 虽然此句没有直接提到whales的特征，但我们可以根据刚刚提到的类比关系做一步逻辑推断啊。既然leatherback turtle很像whales, 那么leatherback turtle的特征也应该就是whales的特征，因此我们只要找到leatherback turtle的描述信息即可发现whales的特征。原文最后一句话提到， leatherback turtle会游到寒冷的南北海洋并且有特殊的处理冰水的能力。于是乎我们可以得出whales也有相同特征。答案对应B选项。
再来看一道稍难的题目吧
Buck rubs also have a scent. These odors make buck rubs an important means of olfactory communication. Forehead rubbing by male deer on buck rubs presumably sends a great deal of information to other members of the same species. The presence of many well-marked rubs is indicative of older, higher-status males being in the general vicinity rather than simply being a crude measure of relative deer abundance in a given area. The information conveyed by the olfactory signals on a buck rub make it the social equivalent of some auditory signals in other deer species, such as trumpeting by bull elk.
What can be inferred from paragraph 4 about the trumpeting of bull elk?
A.Trumpeting by higher-status bull elk signals their presence to other members of their species.
B.Bull elk need to combine trumpeting with olfactory signals to covey information about their identity.
C.Trumpeting alerts white-tailed deer to the presence of bull elk in their vicinity.
D.Trumpeting provides a better measure of deer presence in a given area than buck rubs do.
此题问我们，根据第四段我们可以对trumpeting of bull elk做出怎样的推断。根据关键词trumpeting of bull elk我们快速找到原文最后一个单词。既然是出现在文章的最后位置，那我们只好去往前推了。而前句又提到了一个我们非常熟悉的逻辑关系—─类比关系。来看这句话 The information conveyed by the olfactory signals on a buck rub make it the social equivalent of some auditory signals in other deer species, such as trumpeting by bull elk.这句话告诉我们buck rub发出的olfactory signal和trumpeting of bull elk发出的auditory signal有相同的社会作用。根据前文我们知道buck rub可以反映年长雄鹿在鹿群里的社会地位。于是乎我们便可以做进一步推理，即trumpeting of bull elk也应该有相似地功能。
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 agriculture—of the development 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 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 lived 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 been 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 to 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 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 at 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 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 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 occurred 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。
托福备考之阅读技巧与方法介绍
一、 托福阅读方法
1. 精读的方法
精读是指认真地阅读文章中的每一句话，掌握句子的含义，弄清句子间的逻辑关系，从而理解整段话甚至全文的内容。精读的基础主要是词汇量和语法。在阅读理解中主要体现在长难句的理解上。如果这些句子影响对文章的理解，就必须要花费较长的时间认真阅读，以求获得准确的理解。
2. 意群阅读法
语言是用来传递信息的，阅读的目的就是为了获取信息，因此只要能够准确地把握信息即可。要想在比较短的时间内掌握足够多的信息，我们就必须学会意群阅读法。这就要求我们在阅读的时候不要把注意力放在每一个单词上，而是要以意群(主要包括词组、固定搭配和完整的句意组合)为单位，将注意力放在关键词上，从而掌握该句所表达的含义。
二、托福阅读技巧
1. 把握词义
阅读过程中我们不免会遇到生词，有些考生在阅读中一遇到生词就停下来查字典，这种方法是不正确的。有些词确实会影响到理解，查字典当然是一种办法，但是频繁地查字典不仅会影响阅读速度，还会影响对文章整体内容的理解。所以，考生在平时要学会处理阅读中的生词，掌握猜测生词的方法。
2. 理清结构
阅读时，要先辨别清楚文章的体裁，理清文章的结构，把握主旨大意，找出文章的主题句。理清文章结构有助于考生从整篇文章考虑，选出正确答案，避免因考虑不周或考虑片面而造成理解上的偏差。阅读文章后的问题一般也是按照文章结构顺序提出的，所以理清文章结构还有助于考生在尽量短的时间内找到问题的答案。
3. 分析选项
学会分析选项对于提高阅读分数有着重要的意义。阅读选项的干扰项可能是下面几种情况：1)与文章细节部分相同、部分相悖;2)选项本身是正确的，但不是问题的答案，不符合题干的要求;3)与常识相符合，但在文章中没有提及;4)明显与文章信息不符等等。掌握题目选项特点有助于考生在较短的时间里做出准确的选择。
4. 扩大知识面
扩大知识面对于提高阅读题目正确率来说十分重要。如果考生对阅读文章的话题一无所知，在做题的时候必然会感到很迷茫，理解文章大意时也会很困难。如果考生平时注意扩大知识面，多了解各方面的知识，那么在阅读时就会感到很轻松。
