在做GMAT句子改错的时候,我们强调逻辑语义优先,首先分析原句的逻辑语言是否合理,如果原句逻辑语义合理,那么我们不能改变原句合理语义,那怎么靠逻辑语义来排除不合理选项,得出最终答案,今天雷哥GMAT老师举几个例子来分析,希望对大家有所帮助。



【OG18-P708-805题】

Although she was considered among her contemporaries to be the better poet than her husband, later Elizabeth Barrett Browning was overshadowed by his success.

 

A.Although she was considered among her contemporaries to be the better poet than her husband, later Elizabeth Barrett Browning was overshadowed by his success.

 

B.Although Elizabeth Barrett Browning was considered among her contemporaries as a better poet than her husband, she was later overshadowed by his success.

 

C.Later overshadowed by the success of her husband, Elizabeth Barrett Browning’s poetry had been considered among her contemporaries to be better than that of her husband.

 

D.Although Elizabeth Barrett Browning’s success was later overshadowed by that of her husband, among her contemporaries she was considered the better poet.

 

E.Elizabeth Barrett Browning’s poetry was considered among her contemporaries as better than her husband, but her success was later overshadowed by his.

这道题正确答案是D选项。下面我们从逻辑语义的角度来进行分析:

首先,这道题全部划线,考察逻辑语义,原句说的是尽管在同代人中她比她丈夫好,但EBB被 his success overshadowed,人被success overshadow逻辑语义错,排除AB;

C选项overshadowed 的逻辑主语是poetry,语义错;

E选项用poetry和her husband比较,逻辑上作评和人不能比较,错。

 


【OG18-P699-762题】

A mutual fund having billions of dollars in assets will typically invest that money in hundreds of companies, rarely holding more than one percent of the shares of any particular corporation.

 

A.companies, rarely holding more than one percent

 

B.companies, and it is rare to hold at least one percent or more

 

C.companies and rarely do they hold more than one percent

 

D.companies, so that they rarely hold more than one percent

 

E.companies; rarely do they hold one percent or more

这道题正确选项是A选项。下面我们从逻辑语义的角度来进行分析:

分析下来,A选项逻辑语义没毛病,主语是fund,谓语will invest,holding做invest的伴随状语,逻辑主语是fund,原句是SVO, doing的结构;

BC选项多了and,句子关系改变,变成了SVO and 的结构;

D so that和E ;也改变了句子的合理语义。原句是doing伴随结构来修饰fund,BCDE的休书关系均改变了。



【OG18-P696-747题】

Researchers studying the brain scans of volunteers who pondered ethical dilemmas have found that the basis for making tough moral judgments is emotion, not logic or analytical reasoning.

 

A.the brain scans of volunteers who pondered ethical dilemmas have found that the basis for making tough moral judgments is

 

B.the brain scans of volunteers who pondered ethical dilemmas and found the basis to make tough moral decisions to be

 

C.the brain scans of volunteers pondering ethical dilemmas and found that the basis for making tough moral decisions is

 

D.volunteers’ brain scans while pondering ethical dilemmas have found the basis to make tough moral judgments to be

 

E.volunteers’ brain scans while they pondered ethical dilemmas have found that the basis for making tough moral judgments is

这道题的正确选项是A选项。下面我们从逻辑语义的角度来进行分析:

原句SVO齐全,语义上没毛病,A选项暂时保留。

BC选项加了and 改变逻辑语义;

D选项pondering的逻辑主语不应该是volunteers’ brain,而应该是volunteers;

E选项代词they指代有语义错误。

 

GMAT SC部分的题,我们要遵循逻辑语义优先,上面的三题只是一个实例,希望大家在做题目和分析题目的时候,首先从语义的角度去思考是否合理,这才是做SC题目的关键所在。
