小伙伴们，GMAT考试复习的怎么样了呢？下面帮考网带来了语法部分的复习资料，一起来看看吧！

修饰(占比：60% 难度：中等)。

修饰包含四种修饰关系：定语、状语、同位语和插入语。

在修饰当中，经常作为出题点的比如说：短语在句首;逗号doing在结尾，表结果或伴随。

举个例子：

By sucking sap from the young twigs of the hemlock tree, tree growth is retarded by the woolly adelgid, causing needles to change color from deep green to grayish green and to drop prematurely.

A.tree growth is retarded by the woolly adelgid, causing needles to change color from deep green to grayish green and to drop

B.tree growth is retarded by the woolly adelgid, and this causes the color of needles to change from deep green to grayish green, and their dropping

C.the woolly adelgid retards tree growth, which causes needles to change color from deep green to grayish green, and dropping

D.the woolly adelgid retards tree growth, causing needles to change color from deep green to grayish green and to drop

E.the woolly adelgid retards tree growth, and this causes the color of needles to change from deep green to grayish green, and then their dropping

题目分析：

介词短语放句首做状语，要跟主句的逻辑主语形成合理的逻辑关系，根据语义是adelgid suck sap,所以主句主语因该是adelgid;定语从句修饰名词，doing放句末可做伴随状语或结果状语，修饰句子;

选项分析：

A选项。主语是tree growth不能发出suck sap这个动作，语义不合理;

B选项。同A，逻辑主语错误;添加连词and改变原句语义重心;

C选项。which引导非限制性定语从句修饰tree growth不合理;to change and dropping不平行;

D选项。正确，causing做结果状语;

E选项添加and改变原句语义重心。

3、逻辑

(占比：50% 难度：中高等)

逻辑是一种关系，在SC中体现的是句子的关系，句子与句子间的相互关系，一个句子内部的搭配关系和修饰关系。

举个例子：

Turning away from literary realism to write romantic stories about the peasant life and landscape of northern Sweden, in 1909 Selma Lagerl?f was the novelist who became the first woman and was also the first Swedish writer to win the Nobel Prize for Literature.

A.Turning away from literary realism to write romantic stories about the peasant life and landscape of northern Sweden, in 1909 Selma Lagerl?f was the novelist who became the first woman and was also the first Swedish writer to win

B.She turned away from literary realism and wrote romantic stories about the peasant life and landscape of northern Sweden, and novelist Selma Lagerl?f in 1909 became the first woman as well as the first Swedish writer that won

C.Selma Lagerl?f was a novelist who turned away from literary realism to write romantic stories about the peasant life and landscape of northern Sweden, and in 1909 she became the first woman in addition to the first Swedish writer winning

D.A novelist who turned away from literary realism to write romantic stories about the peasant life and landscape of northern Sweden, Selma Lagerl?f became in 1909 the first woman and also the first Swedish writer to win

E.As a novelist, Selma Lagerl?f turned away from literary realism and wrote romantic stories about the peasant life and landscape of northern Sweden, in 1909 becoming the first woman and also the first Swedish writer that won

选项分析：

A选项：分词短语在句首，逻辑主语要立马给出，Selma Lagerl?f逻辑主语前家里时间状语不符合表达习惯。状语in 1909修饰其身后的句子Selma Lagerl?f was the novelist，这是不正确的。不能说SL这个人在1909年才成为小说家，而是SL一直是小说家，到了1909年才获奖。因此，1909应该修饰 Selma Lagerl?f became the first woman。且主干是SL是小说家，获奖做成了修饰，这个句子之间的主次关系不对，主干和修饰互换。

B选项：as well as虽然可以是连词，但其连接两者的后者在地位上要弱于前者，这点和and不同，and是纯粹的并列。在本题中，两个角色显然没有强弱区别，因此as well as需改为and。另外，She turned away from…and Selma Lagerl?f became…，and增加句子关系。

C选项：副词in addition to需改为并列连词and，became the first woman和was also the first Swedish write应具有并列关系。另外，and增加句子关系，该错误原理同(B)。

D选项：Correct. 本选项在语法和逻辑上均是正确的。

E选项：主次颠倒，逻辑语义变。
