GMAT句子改错-倒装结构

2016-07-21 15:18:27 发布 来源:GMAT备考资讯

在GMAT句子改错中,常常会碰到倒装的结构,有时是全句倒装,有时是部分倒装。那什么情况才会使用倒装结构呢?考生又该如何识别倒装呢?雷哥GMAT总结如下:

一、全句倒装

1.表语放句首,要用全句倒装结构

介词短语/分词短语/形容词性短语+系动词+主语

介词短语放句首

Among the people was the woman named Sarah.

分词短语放句首

Visiting the Forbidden City were the college students.

形容词性短语放句首

Present at the meeting is our director.

PS:全句倒装需要注意谓语动词的单复数一定要和后面的主语保持一致。

 

2.为了使句子结构平行,用全句倒装。

Eg:The students arrived at a palace, in front of which sat a little girl.

 

实战演练

On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow, as seen in the rings visible in the cross sections of their trunks.

A. On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow  

B. On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth  

C. On Earth, the rate at which trees grow is believed to be among the surest indications of sunspot cycles  

D. Among the surest indications on Earth of sunspot cycles, believed to be the tree growth rate  

E. Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow

窗体底端

    雷哥GMAT解析:among the surest indications of sunspot cycles是介词短语放句首,是全句倒装结构,主语是the rate,根据主谓一致可以排除AB选项,D选项主句无谓语排除。未划线部分的as seen.....这个状语从句是修饰at which trees grow, 修饰成分要靠近被修饰对象,排除C,答案E.

 

触类旁通

 The Achaemenid empire of Persia reached the Indus Valley in the fifth century B.C.,bringing the Aramaic script with it, from which was derived both northern and southern Indian alphabets.

A. the Aramaic script with it, from which was derived both northern and

B. the Aramaic script with it, and from which deriving both the northern and the

C. with it the Aramaic script, from which derive both the northern and the

D. with it the Aramaic script, from which derives both northern and

E. with it the Aramaic script, and deriving from it both the northern and

雷哥GMAT解析:from which也是介词短语,所以是倒装结构,根据判断从句中的主语是alphabets,因此谓语动词要用复数,排除AD选项,原句没有平行关系,加上and改变语义,排除BE.答案C.

 

二、部分倒装

1.if引导的虚拟条件句,省略if时需要把助动词(had/were)提前,形成部分倒装。

Were I a bird, I could fly.

2.so/such引导的倒装结构

So lucky is she that she succeeds in the competition.

 

实战演练

Were it not for the fusion-powered heat and radiation that rush from its core, instead its own weight would cause a star to collapse.

A. instead its own weight would cause a star to collapse  

B. instead a star would have collapsed under its own weight  

C. a star would have to be collapsing under its own weight  

D. a star would collapse under its own weight  

E. its own weight would have caused a star's collapse

雷哥GMAT解析:were it是if的省略结构,补充完整是if it were....,主句用情态动词+动词原形。并且主句要立马给出主语,排除ABE,C选项表达太啰嗦,答案D.

 

触类旁通

An array of tax incentives has led to a boom in the construction of new office buildings; so abundant has capital been for commercial real estate that investors regularly scour the country for areas in which to build.

A. so abundant has capital been for commercial real estate that  

B. capital has been so abundant for commercial real estate, so that  

C. the abundance of capital for commercial real estate has been such,  

D. such has the abundance of capital been for commercial real estate that  

E. such has been an abundance of capital for commercial real estate,  

雷哥GMAT解析:

原句中so abundant是部分倒装结构,还原为capital has been so abundant for....that....;

B选项so...so that用法错误;C选项such后需要that;D选项such has 用法错误;                     

E选项such has用法错误;答案A.
