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：
In an effort to reduce their inventories, Italian vintners have cut prices; their wines have been priced to sell, and they are.
(A) have been priced to sell, and they are
(B) are priced to sell, and they have
(C) are priced to sell, and they do
(D) are being priced to sell, and have
(E) had been priced to sell, and they have
选项分析：
(A)have been priced to sell, and they are
【错误】 见(C)。
(B)are priced to sell, and they have
【错误】 见(C)。
(C)are priced to sell, and they do
【正确】 “they do”是“they do sell”省略后的结果。
【大意】 为了降低他们的库存，意大利酿酒商已经降价了;他们的酒被降价销售，且他们确实把酒卖了。
(D)are being priced to sell, and have
【错误】 见(C)。
(E)had been priced to sell, and they have
【错误】 见(C)。
解题思路：
本题只能靠句子意思的分析得出答案。分号之后的部分本意是“他们(意大利酿酒商)的酒被降价卖，并且他们确实卖。”。因此一般现在时的“are priced to sell”语义合理，而且“they do”是强调句“they do sell”唯一正确的省略方式，因此只能选择(C)。
