  GMAT语法题，又称句子改错题(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，想要做好语法题难度极高。怎样做好GMAT语法题?下面小编就通过一些经典真题的实例解析，为大家全面讲解GMAT语法题的解题思路和方法技巧。
  实例题目：
  It is called a sea, but the landlocked Caspian is actually the largest lake on Earth, which covers more than four times the surface area of its closest rival in size, North America’s Lake Superior.
  (A) It is called a sea, but the landlocked Caspian is actually the largest lake on Earth, which covers
  (B) Although it is called a sea, actually the landlocked Caspian is the largest lake on Earth, which covers
  (C) Though called a sea, the landlocked Caspian is actually the largest lake on Earth, covering
  (D) Though called a sea but it actually is the largest lake on Earth, the landlocked Caspian covers
  (E) Despite being called a sea, the largest lake on Earth is actually the landlocked Caspian, covering
  选项分析：
  (A)It is called a sea, but the landlocked Caspian is actually the largest lake on Earth, which covers
  【错误】 修饰成分：定语从句“which covers……”本意上修饰“the largest lake”或“Caspian”，因此构成了跳跃修饰(与“which”就近的是“Earth”)，正确选项应尽量避免跳跃修饰，因此本选项逊于(C)——“，covering”是“is actually the largest lake”
  的伴随状语(只有针对定语才讨论是否存在跳跃修饰的问题)，与其同(逻辑)主语“Caspian”。
  (B)Although it is called a sea, actually the landlocked Caspian is the largest lake on Earth, which covers
  【错误】 修饰成分：类似地，见(A)。
  (C)Though called a sea, the landlocked Caspian is actually the largest lake on Earth, covering
  【正确】 “Though called a sea” 属于从句省略，根据从句省略的语法要求，被“called a sea”的是主句的主语“landlocked Caspian”，表意合理。“covering……”是“is actually the largest lake on Earth”的伴随状语，两者(逻辑)主语同为“landlocked Caspian”，表意合理。
  【大意】 尽管被称作海，内陆湖里海实际上是地球上最大的湖，覆盖面积是仅次之的北美五大湖之Superior湖的四倍。
  (D)Though called a sea but it actually is the largest lake on Earth, the landlocked Caspian covers
  【错误】 句子结构：“though”和“but”，在一对转折关系中只用其一，不得同时使用。
  (E)Despite being called a sea, the largest lake on Earth is actually the landlocked Caspian, covering
  【错误1】 句子意思：“Despite being called a sea, the largest lake on Earth is actually the landlocked Caspian”中“被称作海”与“地球上最大的内陆湖是里海”是一对转折关系，但这种转折关系并不合理。
  【错误2】 简洁明了：动名词“being”在GMAT考察的标准书面英语中不具有简洁性。
  解题思路：
  “though”和“but”不应放在同一个转折关系里，立即排除(D)。
  (A)、(B)存在正确选项应尽量避免的结构——跳跃修饰，(E)中“being”不具有简洁性，因此选择(C)。
