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：
Spanning more than 50 years, Friedrich Müller began his career in an unpromising apprenticeship as a Sanskrit scholar and culminated in virtually every honor that European governments and learned societies could bestow.
(A) Müller began his career in an unpromising apprenticeship as
(B) Müller’s career began in an unpromising apprenticeship as
(C) Müller’s career began with the unpromising apprenticeship of being
(D) Müller had begun his career with the unpromising apprenticeship of being
(E) the career of Müller has begun with an unpromising apprenticeship of
选项分析：
(A)Muller began his career in an unpromising apprenticeship as
【错误】 修饰成分：语法上讲，“Spanning more than 50 years(横跨50年)”的逻辑主语是“Muller”，但这并不合理。本意上其逻辑主语应为“Muller’s career(Muller的事业)”，因此本应“Muller’s career”做主语，与伴随状语“Spanning more than 50 years”形成逻辑上的主谓关系。
(B)Muller's career began in an unpromising apprenticeship as
【正确】 “Muller's career”做主语使得状语“ Spanning more than 50 years”搭配上合理的逻辑主语。“began in”和“culminated in”用“and”平行在一起形成了既正确又工整的平行结构。
【大意】 跨越50余年，Friedrich Muller的职业生涯从一个不起眼的Sanskrit学者的学徒开始并在每一个政府和学术社团能授予的荣誉中达到巅峰。
(C)Muller's career began with the unpromising apprenticeship of being
【错误】 固定搭配：“apprenticeship as”表意为“作为(某种身份)的学徒工作”，“apprenticeship of being”不能表达这一含义。
(D)Muller had begun his career with the unpromising apprenticeship of being
【错误1】 修饰成分：见(A)。
【错误2】 固定搭配：见(C)。
(E)the career of Muller has begun with an unpromising apprenticeship of
【错误1】 动词时态：现在完成时的“has begun”的使用并不合理，“Muller”的“career”已经结束，因此“开始”并不是一个过去发生且对现在仍然有影响的动作。
【错误2】 固定搭配：类似地，见(C)。
解题思路：
通过判断“Spanning more than 50 years”的逻辑主语，可以排除(A)、(D)。
(E)误用了现在完成时，排除。
(C)中即便不知道“apprenticeship of”的用法有问题，“of being”也是不具有简洁性的表达方式，因为动名词“being”表达不出任何增量的信息，排除。
因此选择(B)。
