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：

Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were last year.

(A) Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were

(B) Heating-oil prices are expected to rise higher this year over last because refiners pay about $5 a barrel for crude oil more than they did

(C) Expectations are for heating-oil prices to be higher this year than last year’s because refiners are paying about $5 a barrel for crude oil more than they did

(D) It is the expectation that heating-oil prices will be higher for this year over last because refiners are paying about $5 a barrel more for crude oil now than what they were

(E) It is expected that heating-oil prices will rise higher this year than last year’s because refiners pay about $5 a barrel for crude oil more than they did

选项分析：

(A)Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were

【正确】 “last”和“this”是平行的，“last”是“last year”省略后的结果，将省略部分补齐之后，比较句式为“Heating-oil prices are expected to be higher this year than(it was)last(year)”，本质上是“Heating-oil prices are expected to be”和“it was”之间的比较，因此本选项正确使用了“more……than……”的比较句式。

【错误】供暖用油的价格预期今年会比去年更高，因为炼油厂为每桶原油在比上一年多支付5美元。

(B)Heating-oil prices are expected to rise higher this year over last because refiners pay about $5 a barrel for crude oil more than they did

【错误】比较结构：如果将两个对象进行比较，“more”应和“than”搭配使用，而不是和“over”。

(C)Expectations are for heating-oil prices to be higher this year than last year's because refiners are paying about $5 a barrel for crude oil more than they did

【错误】比较结构：比较结构中，比较对象须平行可比，本选项中“this year”(时间状语)和“last year's”(“去年的(油价)”，名词性结构)不平行，无法构成平行可比的比较句式。

(D)It is the expectation that heating-oil prices will be higher for this year over last because refiners are paying about $5 a barrel more for crude oil now than what they were

【错误】比较结构：本选项使用了“more……than……”引导的比较句式，比较句式的本质是两个平行可比的主谓结构。本选项中“ refiners are paying about $5 a barrel more for crude oil now than what they were”的两个主谓结构“refiners are paying”(一

般的主谓结构)和“what they were”(“what”引导的从句)语法结构不一致，无法平行可比。

(E)It is expected that heating-oil prices will rise higher this year than last year's because refiners pay about $5 a barrel for crude oil more than they did

【错误】比较结构：见(C)。

解题思路：

只有(A)选项使用了正确的比较结构，遵守了“比较对象平行可比”的原则，因此选择(A)。
