GMAT语法的难度体现在每道题目的选项都包含多个语法考点，所以考生是否能够在较短时间尽可能多地排除错误选项缩小考虑范围成为了衡量语法能力和得分的重要标准。下面小编就来具体介绍从一致性考点入手快速排除GMAT语法错误选项的技巧。
GMAT语法一致性考点是什么？
所谓语法一致性就是谓语动词和主语在单、复数形式上保持一致。这个考点光从字面上来看貌似十分简单，但涉及到具体题目中却往往会成为突破关键。具体来说，在GMAT语法中有关一致性的具体考点主要有以下8种：
1. 主语谓语单复数一致
以单数名词或代词、动词不定式短语、动名词短语或从句作主语时，谓语动词一般用单数形式;主语为复数时，谓语动词用复数形式。
如：His father is working on the farm. / To study English well is not easy. /
What he said is very important for us all. / The children were in the classroom
two hours ago. / Reading in the sun is bad for your eyes.
注意：由what引导的主语从句，后面的谓语动词多数情况用单数形式，但若表语是复数或what从句是一个带有复数意义的并列结构时，主句的谓语动词用复数形式。如：What
I bought were three English books. / What I say and do is (are) helpful to
you.
2. 合成主语用复数
由连接词and或both …… and连接起来的合成主语后面，要用复数形式的谓语动词。
如：Lucy and Lily are twins. / She and I are classmates. / The boy and the girl
were surprised when they heard the news. / Both she and he are Young
Pioneers.
注意：(1)若and所连接的两个词是指同一个人或物时，它后面的谓语动词就应用单数形式。如：The writer and artist has come.
(2)由and连接的并列单数主语前如果分别有no， each， every more than a (an) ， many a
(an)修饰时，其谓语动词要用单数形式。如：Every student and every teacher was in the room. / No boy
and no girl likes it.
3. 短语不影响单复数形式
主语为单数名词或代词，尽管后面跟有with， together with， except， but， like， as well as， rather
than， more than， no less than， besides，
including等引起的短语，谓语动词仍用单数形式;若主语为复数，谓语用复数形式。
如：Mr. Green， together with his wife and children， has come to China. / Nobody
but Jim and Mike was on the playground. / She， like you and Tom， is very
tall.
4. 复合不定代词的单复数判定
either， neither， each， every 或no +单数名词和由some， any， no，
every构成的复合不定代词，都作单数看待。
如：Each of us has a new book. / Everything around us is matter.
注意：(1)在口语中当either或neither后跟有“of+复数名词(或代词)”作主语时，其谓语动词也可用复数。如：Neither of the
texts is (are) interesting. (2)若none
of后面的名词是不可数名词，它的谓语动词就要用单数;若它后面的名词是复数，它的谓语动词用单数或复数都可以。如：None of us has (have)
been to America.
5. 关系代词做主语的单复数一致
在定语从句时，关系代词that， who， which等作主语时，其谓语动词的数应与句中先行词的数一致。
如：He is one of my friends who are working hard. / He is the only one of my
friends who is working hard.
6. 集体名词单复数使用区别
如果集体名词指的是整个集体，它的谓语动词用单数;如果它指集体的成员，其谓语动词就用复数形式。这些词有family， class， crowd，
committee， population， audience等。
如：Class Four is on the third floor. / Class Four are unable to agree upon a
monitor.
注意：people， police， cattle等名词一般都用作复数。如：The police are looking for the lost
child.
7. 数量词构成短语注意单复数用法
由“a lot of， lots of， plenty of， the rest of， the majority of +
名词”构成的短语以及由“分数或百分数+名词”构成的短语作主语，其谓语动词的数要根据短语中后面名词的数而定。
如：There are a lot of people in the classroom. / The rest of the lecture is
wonderful. / 50% of the students in our class are girls.
注意：a number of“许多”，作定语修饰复数名词，谓语用复数;the number of“……的数量”，主语是number，谓语用单数。
8. 倒装句中动词单复数问题
在倒装句中，谓语动词的数应与其后的主语一致。如：There comes the bus. / On the wall are many pictures.
/ Such is the result. / Such are the facts.
假如考生能够对上文提到的这8种涉及到GMAT语法一致性的具体问题有充分了解和掌握，那么想要迅速解决一些语法难题或者缩小选项范围排除大部分错误选项就不会太过困难了。
