2015年GMAT句子改错练习题及详细解析汇总
43. Laos has a land area about the same as Great Britain but only four million in population, where many are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.
(A) about the same as Great Britain but only four million in population, where many
(B) of about the same size as Great Britain is, but in Laos there is a population of only four million, and many
(C) that is about the same size as Great Britain’s land area, but in Laos with a population of only four million people, many of them
(D) comparable to the size of Great Britain, but only four million in population, and many
(E) comparable to that of Great Britain but a population of only four million people, many of whom
答案解析如下：
(A)about the same as Great Britain but only four million in population, where many
【错误1】 比较结构：“about the same as”比较的是“Great Britain”和“land area”，并不可比。
【错误2】 修饰成分：在GMAT考察的标准书面英语中，“where”用来修饰具体或抽象的方位，但“population”并非是一个方位的概念。
(B)of about the same size as Great Britain is, but in Laos there is a population of only four million, and many
【错误1】 比较结构：类似地，见(A)。
【错误2】 句子意思：根据日常逻辑，“many”本意指“很多老挝人”，相比(E)用“many of whom”修饰“people”但本选项的并不能明确地表达这个本意。
【错误3】 简洁明了：“there be”结构在GMAT考察的标准书面英语中不具有简洁性。
(C)that is about the same size as Great Britain\'s land area, but in Laos with a population of only four million people, many of them
【错误1】 句子意思：“but in Laos with a population of only four million people, many of them……”大意为“但是在有一个400万人口的老挝中，他们中许多……”，含义逊于(E)中“many of whom……”与“four million people”之间的修饰关系。
【错误2】 简洁明了：“that is”、“who is”、“which is”等结构不具有简洁性。
(D)comparable to the size of Great Britain, but only four million in population, and many
【错误】 句子意思：见(B)中【错误2】。
(E)comparable to that of Great Britain but a population of only four million people, many of whom
【正确】 “that of Great Britain”中的“that”指代“land area”，因此可与“Laos has a land area”中的“a land area”进行比较。“many of whom”引导的定语从句明确地修饰了“four million people”。
【最优解题思路推荐】
老挝的土地面积应与英国的土地面积比较，因此(D)和(E)比较对象平行可比。
(E)中后半句中“many of whom”和“four million people”的修饰关系，优于(D)中“and many……”的平行结构。因此选择(E)。
