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：
The report recommended that the hospital should eliminate unneeded beds, expensive services should be consolidated, and use space in other hospitals.
(A) should eliminate unneeded beds, expensive services should be consolidated, and use space in other hospitals
(B) should eliminate unneeded beds, expensive services should be consolidated, and other hospitals’ space be used
(C) should eliminate unneeded beds, expensive services should be consolidated, and to use space in other hospitals
(D) eliminate unneeded beds, consolidate expensive services, and other hospitals’ space used
(E) eliminate unneeded beds, consolidate expensive services, and use space in other hospitals
选项分析：
(A)should eliminate unneeded beds, expensive services should be consolidated, and use space in other hospitals
【错误】 见(E)。
(B)should eliminate unneeded beds, expensive services should be consolidated, and other hospitals' space be used
【错误】 见(E)。
(C)should eliminate unneeded beds, expensive services should be consolidated, and to use space in other hospitals
【错误】 见(E)。
(D)eliminate unneeded beds, consolidate expensive services, and other hospitals' space used
【错误】 见(E)。
(E)eliminate unneeded beds, consolidate expensive services, and use space in other hospitals
【正确】 “eliminate unneeded beds”、“consolidate expensive services”、“use space in other hospitals”三者正确地构成了“A，B，and C”的平行结构。
【大意】 报告建议医院较少不需要的床位、合并昂贵的服务、使用其他医院的空间。
解题思路：
只有(E)选项将“eliminate……”、“consolidate……”和“use……”用一个“and”并列在一起，形成了正确的“A，B，and C”平行结构。不仅如此，recommend属于“bossy words”之一，其后的从句应使用省略“should”的虚拟语气，在GMAT考察的标准书面语中“should”如果不省略则存在语义重复，因此(A)、(B)、(C)中的“should”是多余的。
