托福阅读一定要读完全文吗？

托福阅读考试的过程中，不少考生反映阅读材料根本来不及读完，时间就没有了，怎么解决这个问题呢?今天小编就教你托福阅读的套路。

题目1：

A symbiotic relationship is an interaction between two or more species in
which one species lives in or on another species. There are three main types of
symbiotic relationships: parasitism, commensalism, and mutualism. The first and
the third can be key factors in the structure of a biological community; that
is, all the populations of organisms living together and potentially interacting
in a particular area.

1. Which of the following statements about commensalism can be inferredfrom
paragraph 1?

○It excludes interactions betweenmore than two species.

○It makes it less likely for specieswithin a community to survive.

○Its significance to the organizationof biological communities is
small.

○Its role in the structure ofbiological populations is a disruptive
one.

✔解法1：

初学者在看到这样题目的时候，会先把文章看完甚至翻译一遍，认为理解了自然就能选对答案。这是正确率靠谱的做法，但*大的缺陷是考试时无法在短时间内理解文章并且做完题目。所以在阅读能力不是很强的时候，尽量不要使用看完理解再做题的方法。

✔解法2：定位规律

• 题干关键词：commensalism

• 文中定位点：There are three main types ofsymbiotic relationships: parasitism,
commensalism,and mutualism.有三种共生关系：寄生、共生、互利共栖。说的是题干关键词本身的内容，无法对应选项。

• 再往后读啊读啊读啊……理论上来说看到这里应该能得到答案了，但是……但是……看看选项?

○共生关系不包括超过两个物种之间的相互作用

○共生关系使得物种在生物团体中难以生存

○共生关系在生物群体中的重要性是小的

○共生关系在生物结构中的角色是引起混乱的

选哪个?!正确答案是哪个啊?这里我们要学的是一个小套路，我们把文中内容和选项都理解后得到这样的一个逻辑：

文章：*个和第三个在一个生物团体结构中是重要的;意思是，所有的有机体居住在一起并且在特定的区域相互作用。

推理模式：*个(寄生)和第三个(互利共栖)在一个生物团体结构中是重要的→第二个(共生)是不重要的

☞所以选C

这个切入点你发现了吗?

但这样分析题目，对我们来说有什么实际的意义呢?同学们，这篇文章的核心就是希望大家能高效的发现题目的切入点并且解决问题。于是，对于这道题来说发现一个能够广泛使用的规律，比起选出正确答案更有意义：让我们聊聊刚才在题目中的推理模式：*个(寄生)和第三个(互利共栖)在一个生物团体结构中是重要的→第二个(共生)是不重要的。

这个推理模式我叫做反义推理(有些老师也叫做反向推理、取非，意思一致)，是托福阅读推理题常用的推理模式，并且在细节题、否定事实信息题(NOTEXCEPT)和判断其他题型错误选项的时候经常使用，也是*常见的一种思维模式。反义推理的核心来自于归约(reduction)，意思是当未知量与已知量看上去无法匹配的时候，在二者之间搭上一个桥梁来使得找答案变得更简单。

题目2：

With question such as these clearly before them, the scientists aboard the
Glomar Challenger processed to the Mediterranean to search for the answers.On
August 23, 1970, they recovered a sample. The sample consisted of pebbles of
hardened sediment that had once been soft, deep-sea mud, as well as granules of
gypsum and fragments of volcanic rock. Not a single pebble was found that
mighthave indicated that the pebbles came from the nearby continent. In the days
following, samples of solid gypsum were repeatedly brought on deck as drilling
operations penetrated the seafloor. Furthermore, the gypsum was found to possess
peculiarities of composition and structure that suggested it had formed on
desert flats. Sediment above and below the gypsum layer contained tiny marine
fossils, indicating open-ocean conditions. As they drilled into the central and
deepest part of the Mediterranean basin, the scientists took solid,shiny,
crystalline salt from the core barrel. Interbedded with the salt were thin
layers of what appeared to be wind blown silt.

4.Which of the following can beinferred from paragraph 3 about the solid
gypsum layer?

○It did not contain any marine fossil.

○It had formed in open-ocean conditions.

○It had once been soft, deep-sea mud.

○It contained sediment from nearby deserts.

✔解析：这道题很容易，和上一题是同样的套路

• 题干关键词：the solid gypsum layer

• 文中定位点：Sediment above and below the gypsumlayer contained tiny marine
fossils, indicating open-ocean conditions.

• 利用反义推理：在石膏层上面和下面的沉积层中包含小海洋化石→石膏层不包含海洋化石

☞所以选A

而在我们熟练了在一个完整概念下不同因素之间的反义推理后(例如整体是【A,B,C】,
文中说AB重要则C不重要，AB有东西则C没有)，将完整概念拓展到时间点前后区分概念会使得做题变得更加的简单。

题目3:

【Paragraph 2】Yet this most fundamental standard of historical periodization
concealsa host of paradoxes. Nearly every movie theater, however modest, had a
piano ororgan to provide musical accompaniment to silent pictures. In many
instances,spectators in the era before recorded sound experienced elaborate
auralpresentations alongside movies' visual images, from the Japanese
benshi(narrators) crafting multivoiced dialogue narratives to original
musicalcompositions performed by symphony-size orchestras in Europe and the
UnitedStates. In Berlin, for the premiere performance outside the Soviet Union
of TheBattleship Potemkin, film director Sergei Eisenstein worked with
Austriancomposer Edmund Meisel (1874-1930) on a musical score matching sound to
image;the Berlin screenings with live music helped to bring the film its
wideinternational fame.

5. Paragraph 2 suggests which of the following about Eisenstein’s film The
Battleship Potemkirf?

○The film was not accompanied by sound before its Berlin screening.

○The film was unpopular in the Soviet Union before it was screened in
Berlin.

○Eisenstein’s film was the first instance of collaboration between a
director and a composer.

○Eisenstein believed that the musical score in a film was as important as
dialogue.

✔解析：

• 题干关键词：Eisenstein’s film The Battleship Potemkirf，大写字母很容易找

• 文中定位点：In Berlin, for the premiereperformance outside the Soviet Union of
The Battleship Potemkin, film directorSergei Eisenstein worked with Austrian
composer Edmund Meisel (1874-1930) on amusical score matching sound to image;
the Berlin screenings with live musichelped to bring the film its wide
international fame.

• 利用反义推理：在柏林首次公演→在柏林之前没有演过

☞所以选A
