今天澎博英语的老师就为大家讲解一下GMAT语法比较结构的这四大题型是哪些，希望通过澎博英语的讲解大家能够对GMAT语法有一个整体了解。

　　一、GMAT语法比较结构的概念

　　GMAT语法中的比较结构是指一个人、事、物与另一个人、事、物或几个人事物之间就行为、性质、特征进行比较，也可以是数量上的比较和对比。比较对象之间如果要能够可比的话，他们首先是概念必须对等，就是说要术语同一个类型的。

　　二、GMAT语法比较结构常考四大题型。

　　1、GMAT语法比较题之like与unlike结构。

　　2、GMAT语法比较题之more than结构。

　　3、GMAT语法比较题之as…as…结构。

　　4、GMAT语法比较题之as作联词的结构。

　　三、GMAT语法比较结构四大题型的考法。

　　1、like与unlike结构考点解析。

　　比较对象对等，且形式对称。这种考点我们可见到四种题型。常见考题结构是：Like A, B+谓语+宾语;Unlike A, B+谓语+宾语。其中A是一个名词，B是主语，like和unlike是一个介词，且like/unlike在GMAT语法比较题中仅表比较不表比喻，其前后的对象应该是同一种类的。一般来说，句首使用like，句尾使用as。

　　2、more than结构考点解析。

　　more than结构的考点也符合比较对象对等，且形式对称的原则，通常我们以than为分割点看前后比较的结构，也就是说than后面的结构在前面一定出现过。如“The diameter of the earth is much longer than the moon.”中，把地球的直径和月亮比是错误的。

　　3、as…as…结构考点解析。

　　在as…as…结构中，第二个as比较重要，第二个as后才给出了比较对象。第二个as后的结构前面一定出现过，且同一结构中的相同单词可以省略，不同结构中的相同单词不可省略。

　　4、as作联词的结构考点解析。

　　此考点有一个重要的要求，就是as后动词取决于与主句的谓语动词，应与主句的谓语动词保持时态与情态的一致性。例如，You have a book as have I./You have a book as do I.(两句都是错的)因为时态不一致，正确的句子应该是：You had have a book as have I./You had have a book as do I.
