GMAT语法改错的难度一方面来自题干，另一方面来自选项，因为我们要依靠选项之间的差别来获得信息、寻求提示，其实这就反映了GMAT语法改错答案的特点--永远只有相对正确而不存在绝对正确。接下来小编就给大家介绍一下GMAT语法题，希望对大家备考GMAT语法考试有帮助。
93. 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
答案解析如下：
(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)。
【最优解题思路推荐】
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)。
