托福阅读同义词替换

第一种:单词替换

这一类型替换其实是语言中最容易辨别的,也就是单词会以原形进行不同的变化。总共有两种不同的变化;

1. 同义词/近义词

原文:The first steps toward change were taken by Solon in594B.C.,when he broke the aristocracy's strangle hold on elected offices by establishing wealth rather than birth as the basis of office holding...

题目:According to paragraph3,an important effect of making wealth the basis of office holding was to

[A]make fewer people qualified to be members of the assembly

[B]make it possible for non-aristocrats to hold office

[C]help the aristocrats maintain power

[D]Increase economic opportunities for all Athenian citizens

原句中的broke the aristocracy’s strangle hold on elected offices 这句话中的broke 为否定词,替换成近义词否定,成为否定前缀non-, 而aristocracy 则替换成同义词,替换成aristocrats。

TPO40 P1T9中也考察了类似变化

原文:Cleisthenes' principal contribution to the creation of democracy at Athens was to complete the long process of weakening family and clan structures...

题目:According to Paragraph 4, one effect of making the demes the point of entry for civic life was to

[A]ensure that every region had the same number of commissioners

[B]distribute the population more equally throughout the Athens region

[C]limit the number of aristocratic clans

[D]reduce the importance of family connections

不难发现原文中的weakening 同义替换成D选项中的reduce,近义词变化,因此答案选D。

这一类型同义替换最主要是考察对于单词的认知,最常见就是相近相似单词的变化,所以在辨识度上面比较容易,对于这样的同义替换现象,其实只要针对固定的单词进行背诵,也就是托福常考的单词类型背诵,其实就可以大大避免错误量。

2. 词组同义替换

TPO40P1T8

原文:By the end of the century,the time was ripe for more change: the tyrants were driven out,andin508B.C.a new reformer, Cleisthenes gave final form to the developments reducing aristocratic control already underway.

题目:The tyrants were driven out, and in 508B.C. Cleisthenes put in place the structures that completed the weakening of the aristocracy

本题中出现的同义替换是词组的同义替换,gave final form替换成completed the weakening , 虽然单词不是特别的难,但是重点在于阅读时不能只阅读单词,而是要以意群式阅读,以词组或者是短语为阅读单位,这样就不容易被此类干扰项混淆。

第二种:逻辑关系词变化

这一种同义替换经常出现在逻辑关系的句子中,也就是句子主语和宾语在单词上并不会有很大的变化,但是关系词变化比较明显,一般在平行结构【and, but,or 】或者在因果关系上最为明显。

如:TPO33P3T3

原文:However, no group or species can maintain its dominance indefinitely, and when, after over 200 million years, the age of dinosaurs came to a dramatic end about 65 million years ago, mammals began to flourish, evolving from relatively few types of small terrestrial animals into the myriad of diverse species, including bats and whales, that we know today.

题目:3.Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?

A.The dominance of dinosaurs came to an end 65 million years ago, at which time mammals began to flourish and diversify.

B.Because no group of species can remain dominant forever, mammals became the dominant group when dinosaurs became extinct.

C.After being the dominant group for more than 200 million years, the age of dinosaurs came to a dramatic end 65 million years ago.

D.The diverse group of mammals that we know today, including bats and whales, evolved from small terrestrial forms that had been dominated by dinosaurs.

该长句其实是2个长句的并列;主要分成2个意思:第一是没有任何一种生物能永远地统治,第二是恐龙灭亡之后,哺乳动物开始发展统治,且两层意思之间可以构成因果关系。所以只有B选项满足所有条件。从此题不难发现在备考过程中一定要熟悉句子内部的逻辑关系,如让步,转折,对比还有因果等关系等。

这一类型的同义替换最重要是能判别出前后二者的关系为何,一旦明确关系后就可以根据逻辑连接词进行干扰项的排除,快速解题。

第三种:句子信息概括

这一类型的同义替换是所有变形中最难也是托福阅读中最难的一部分,大多数情况下这类型句子原文会比较长,甚至有可能是两句话, 而答案会稍短一些,将两句话中的内容综合就可以得出答案。

举例说明:

TPO 40 P1T1

原文:One of the most important changes in Greece during the period from 800B.C.to500B.C.was the rise of the polis, or city-state,and each polis developed a system of government that was appropriate to its circumstances.

题目: Paragraph 1 supports which of the following statements about the Greek city-states?

A. Most city-states followed the model provided by Athens.

B. Most city-states were based on aristocratic rule.

C. Different types of government and organization were used by different city-states.

D. By 500B.C.the city-states were no longer powerful.

题目中的句子是针对原文中那么长的一句内容进行概括, 每一个城邦有一种适应其特征的政权概括起来就是不同的城邦有不同的政权,因此答案应该为C。

本题的概括性其实并没有很难,重点在于了解句意, 并且知道该句的重点内容究竟在何。

如果遇到更长一点的句子,那么重点就在反复讨论的内容和重点细节为何,这一点在TPO31P3T3上特别明显:

原文:In many characteristics, savanna soils are similar to those of some rain forests, though more extreme. For example, savanna soils, like many rain forest soils, are typically oxisols 【dominated by certain oxide minerals】 and ultisols 【soils containing no calcium carbonate】, with a high acidity notably low concentrations of such minerals as phosphorus, calcium, magnesium, and potassium, while aluminum levels are high. Some savannas occur on wet, waterlogged soils; other dry, sandy, well-drained soils. This many seem contradictory, but it only means that extreme soil conditions, either too wet or too dry for forests, are satisfactory for savannas. More moderate conditions support moist forests.

According to paragraph 3, rain forests and savannas differ in that

A.the soils in rain forests contain fewer minerals than savanna soils do.

B.savannas affect soil conditions more than rain forests do.

C.unlike rain forests, savannas prefer sandy, well-drained soils to soils that are very wet.

D.unlike rain forests, savannas may develop under both very dry and very wet soil conditions.

本题的答案其实就是根据该段中的for example一句内容进行概括后得出,不难发现原句句子很长且单词比较具体,而答案中信息则是简洁明了。这就是典型的概括性同义替换,同时题目难度也增加了。应对这一类型题目,需要了解句子中的相关关系,摈弃过于细节的内容,抓主干即可。

托福阅读复杂句的解题技巧

托福阅读的文章中,复杂句也是难道很多同学的地方。其实复杂句看似很难,只要大家掌握到了解答的技巧,一样能够轻松搞定这类句子。为大家整理了相关的技巧,供大家参考。

1简单句即基本句,就是英语在最简单句子中的基本格局、也是千变万化的句子结构的雏形。基本句型主要有五种:

主-动-补【动词就是我们所说的系动词】

主-动【动词就是我们所说的不及物动词】

主-动-宾【动词也就是我们所说的及物动词】

主-动-宾-宾【第三种类型的引申】

主-动-宾-补【这个复杂一点,但是我们经常看到的动词固定表达就是属于这一种】

2复杂句也就是我们经常说的“从句”。从句的目的也是英语语言逻辑的精髓就是“修饰关系”,也就是在一个句子里表达更多的内容和信息。

比如“跟别人告别的时候用力一点,因为你多说一句,可能就是最后一句,多看一眼,可能就是最后一眼…”这是属于原因状语从句、主句却还是一个“祈使句”。再如“在这个忧伤而明媚的三月,我从我单薄的青春里打马而过,穿过紫堇,穿过木棉,穿过时隐时现的悲喜和无常。”这个句子,明明就是一个单句,虽然有“在”、但是后面却接的是一个“三月”,整个句子的主语是“我”。

我们再来看几个托福TPO里的句子你会发现其实并不难。

The transition from forest to treeless tundra on a mountain slop isoften a dramatic one.

肢解开开分析起来简单多了,大家能不能一眼看到句子的核心呢?这句话的核心含义是:过渡带很剧烈。

Within a ver tical distance of just a few tens of meters, treesdisappear as a life-form and are replaced by low shrubs, herbs, and grasses.这句话的意思是:在…,树消失…和被…代替。

This rapid zone of transition is called the upper timberline or tree line.这句话的意思是:这个什么XX的“地带”叫...。

In many semiarid areas there is also a lower timberline where the forest passes into steppe or dese rt at its lower edge, usually because of a lack of moisture.这句话里有了where引导的定语从句,但是把它找出来也就不难理解句子了。这句话的意思为:在…, 有timberline,【一堆东西修饰了timberline】。

托福阅读学术类文章及段落结构解析

托福阅读考试的文章题材种类比较多,来源广泛,因此也增加了大家的考试难度。其实针对不同类型的阅读文章,也有一定的技巧。今天我们重点来讲解的是托福阅读中的学术类文章的结构解析。

1.托福阅读文章之学术篇的结构

在托福阅读学术性文章中,一般需要具备三个组成部分:

【1】Topic 话题:即文章的主角是什么。比如讲解某个科学理论、研究某种社会现象,探讨某个历史事件;

在托福文章中,这种导入性信息往往出现在篇首位置。考生可以根据篇首段信息对整篇文章所要讨论的核心内容有所了解;

【2】Aspects 方面:即将篇首的话题延伸拓展为若干个方面进行阐述说明。若话题为某个科学论点,则方面可能分为若干个支持论据;若话题为某种自然现象,则方面可能分为若干个内外成因;若话题为某个历史事件,则方面为几段发展时期;

在这种托福阅读题材中,往往依照各个方面之间的层次关系,将各个方面拆分为若干个独立的自然段落,共同组成行文主体;

【3】Attitude态度:即文章的作者对于所讨论话题持怎样的态度。或是积极肯定,或是消极否定,或是保持中立。

在托福文章中,态度往往是被较多的淡化甚至有可能省略不提。Topic话题 + Aspects方面 + Attitude态度,这三要素加起来就是标准学术论文体的"T+A+A篇章结构"。托福文章大都遵循这种结构,考生通过篇首段落信息来把控整个文章话题及大致讨论方向,再抓住文章的各个段落主旨,便可洞悉整个文章脉络和逻辑结构。

2.托福阅读学术性文章的段落结构

托福阅读学术性文章的自然段落,一般需要具备两个组成部分:【1】 Topic Sentence

主旨句:表达段落的主旨,即本段想要表达的核心内容是什么;

【2】 Detail 细节:为了详细说明段落中心含义,所罗列的相关支持内容,即本段通过哪些例证来阐明主旨句。

Topic Sentence主旨句 + Detail细节,这两个要素加起来就是标准学术论文体的"TS+D段落结构"。托福文章段落大都遵循这种结构,考生通过段落主旨句就可以把握该段的中心含义。

总结:当考生们了解了这种TAA篇章结构和TS+D段落结构的行文规律后,对文章框架的把握就会做到心里有数,更有利于提高托福阅读速度和定位有效信息的准确度。
