GMAT语法题是sentence correction(改进句子题型)，每道题的A选项与划线部分相同，采取择优选择的方式将划线部分的句子进行改进，如果没有比原句更好的选项则保留原句。下面带大家一起来看一下。
GMAT语法题目既可能是部分划线也可能是全部划线
主要考查三方面语法能力：语法结构、词汇表达、句子逻辑表达
主要考查两大原则：correctness & effectiveness
主要考查四方面语法错误：笨拙表达、模棱两可、冗余过剩、语法错误
选择的答案不一定是最完美的，但是是最优的
例题讲解：
Despite its attractiveness, investing abroad can still pose big risks, ranging from the potential for political instability in some countries to the shortage of regulations to protect investors and a serious lack of information about investments in others.
A.to the shortage of regulations to protect investors and a serious lack of information about investments in others
B.to the shortage of regulations to protect investors and in others a serious lack of information about investments
C.and the shortage of regulations to protect investors and a serious lack of information about investments in others
D.and the shortage of regulations to protect investors to a serious lack of information about investments in others
E. to the shortage of regulations to protect investors in others and a serious lack of information about investments
从句子结构分析：主语是investing abroad, 谓语动词时can pose，raging …是一个伴随状语，句子结构很完整。
从词汇表达来看 from …to…是固定搭配，不可改变选项 CD from..and 被排除
从句子的逻辑表达着手：原句与剩余其他选项相比表达清晰。
GMAT语法考试题型分析及考试攻略
1.题干与选项的阅读方法
1)题干的阅读方法
挑主干(包括从句主干，判断句子基本结构是否完整)
抛修饰(定语、状语、插入语、同位语)
识从句(从句类型，检查相关考点是否正确)
辩标志(平行比较等结构的标志词)
2)选项的阅读方法
选项的首部和尾部进行纵向比较差异寻找考点
选项剩余部分差异对比寻找考点
2. 语法语义层的检验
结合未划线句子部分再次检查绝对性错误
从语义层检验是否符合逻辑以及相对性错误

辨标志： from ….to …and
