GMAT句子改错题(sentence

correction)，是整个GMAT考试中对考生英语语法能力考查要求最高的题型，也往往是中国学生最为头疼的一类题目。没有扎实的语法基础和一定的逻辑分析能力，想要做好句子改错题难度极高。如何提升GMAT句子改错题的解题能力?下面小编就为大家整理了一些经典例题，结合实例分析为大家讲解GMAT句子改错题的解题思路和方法技巧。

实例题目：

Nobody knows exactly how many languages there are in the world, partly

because of the difficulty of distinguishing between a language and the

sublanguages or dialects within it, but those who have tried to count typically

have found about five thousand.

(A) and the sublanguages or dialects within it, but those who have tried to

count typically have found

(B) and the sublanguages or dialects within them, with those who have tried

counting typically finding

(C) and the sublanguages or dialects within it, but those who have tried

counting it typically find

(D) or the sublanguages or dialects within them, but those who tried to count

them typically found

(E) or the sublanguages or dialects within them, with those who have tried to

count typically finding

选项分析：

(A)and the sublanguages or dialects within it, but those who have tried to

count typically have found

【正确】 “it”正确地指代“a language”。

【大意】 没人确切地指代世界上有多少语言，一部分由于区分一种语言及这种语言下属的亚语言和方言的难度，但那些已经数过的人已经大约发现了5000种。

(B)and the sublanguages or dialects within them, with those who have tried

counting typically finding

【错误】

代词指代：GMAT语法中，代词应指代句中已经出现的且与代词数量一致形式的名词性结构，“them”本应指代“language”，但两者数量形式不一致，无法指代。

(C)and the sublanguages or dialects within it, but those who have tried

counting it typically find

【错误】 代词指代：“counting

it”中的“it”语法上只能指代单数的“language”，但语义上，一种“language”是不需要“数”的，因此“it”本意上想指代“languages”，但GMAT语法中代词应指代句中已经出现的且与代词数量一致形式的名词性结构，而此处“it”无所指代。

(D)or the sublanguages or dialects within them, but those who tried to count

them typically found

【错误】 代词指代：见(B)。

(E)or the sublanguages or dialects Within them, with those who have tried to

count typically finding

【错误】 代词指代：见(B)。

解题思路：

除了(A)之外，其他选项均犯了“无法指代”或“无所指代”的代词错误，这类错误在GMAT语法中属于代词的绝对错误，应立即排除(指代不明属于相对错误，需要对比其他选项后选择)，因此只能选择(A)。
