在GMAT语法考试中，主谓一致基本在每个试题中都会出现，判断主谓一致还能为分析好句子结构有帮助。本文就给大家介绍下GMAT句子改错之主谓一致的考试内容。
什么样的句子能够达到主谓一致的要求呢?
首先每个句子都必须有一个主谓结构，其次主语和谓语要在单复数形式和逻辑意义上达到一致。
例如：
The dog with the gray ears runs out of the house.
一、一个完整的句子必须主语谓语同时存在，缺少任何一个都是不完整的。
GMAT句子改错常见错误现象一：把非谓语动词当做谓语。
例：
The electron named in 1894.错误
改正1：Stoney named the electron in 1894.正确。(named作为一般过去时)
改正2：The electron was named in 1894.正确。(named作为被动语态)
因为electron只能被命名，所以named 这单个词不是谓语。
GMAT句子改错常见错误现象二：只有连词引导的从句，无主句。
例：
because the dog was never mine.错误
(在这里because是一个连接词,连接的是一个原因状语从句,很明显这里没有主句)
改正：I don`t like the dog because the dog was never mine.正确 (加上主句)
例：which will be approved tomorrow.错误
(which是个代词也是个连接词，引导的从句，没有主句，是错误的)
改正：The plan will be approved tomorrow.(把which指代的内容写出来)

二、主语和谓语逻辑意思要合理
例：The development of a hydrogen car based on expected performance parameters will be able to travel hundreds of miles without refueling.
本句子主语是development (抽象名词)谓语是will be ，句子意思大概是development 拥有了(be able )了某种能力……这明显在逻辑意思上是错误的。
改正：可以把主语改成具体名词，所以位置换成a hydrogen CAR。
Once developed, a hydrogen CAR based on expected performance parameters WILL BE able to travel hundreds of miles without refueling.

三、主语和谓语单复数要一致(GMAT考试重点考查内容)
例：
The discovery of new medicines (was/were) vital to the company`s growth.
判断方法：根据逻辑意思或者看主语形式。
分析：discovery是抽象名词，抽象名词发出某个具体动作的时候大家要注意这个动作发出得是否合适。根据逻辑意思，discovery是句子的主语，所以谓语选择was.
考点1：由and并列的主语，谓语用复数
例1：Ann and her friend are going to the beach.
And并列的两个人共同作主语，谓语复数。
例2：Mathematics,history,and science are mandatory high-school subject.
And并列的三个做主语，谓语用复数。
考点2：以下结构，谓语动词看A的单复数来决定
A with B;A as well as B; A along with B;A, together with B;A,including B;
A in addition to B;A,accompanied by B.
例1：Joe,as well as his friends, is going to the beach.
例2：History ,in addition to Math and science ,is a required subject.
考点3：or;either……or……;neither……nor……谓语与靠近它的主语单复数就近一致。
例1：Neither the coach nor the players are going to the beach.
例2：Neither the players nor the coach is going to the beach.
细节补充：
1、集合名词作主语，谓语一般用单数。
People：agency，army，audience，class，committee，crowd,orchestra ,team.
Items :baggage,citrus(柑橘类水果的总称),equipment,fleet,fruit,furniture.
例1:The crowd in the stands is cheering loudly as the home team takes the field.
例2：Our army of a hundred thousand soldiers is attacking the enemy.
2、不定代词做主语，谓语一般用单数
以-one，-body，或者-thing结尾的不定代词
Each ，every Whatever ,Whoever either,neither (不加or/nor)
例1：Neither answer is correct.
例2：Everybody is here.
3、特殊的不定代词：some.any,none,all，more/most +of +名词(由该名词单复数决定)
例1：Some of the money was stolen from my wallet.
例2：Some of the documents were stolen from the bank.
4、短语或从句作主语，谓语一般用单数
例1：Having good friends is a wonderful thing.
例2：whatever they want to do is fine with me.
5、倒装结构：还原之后看主语
例1：There is a young man and an older woman at the bus stop.(错误)
还原之后看主语：A young man and an older woman are at the bus stop.
改正：There are a young man and an older woman at the bus stop.(正确)
例2：Near those buildings sit a lonely house.(错误)
还原之后看主语：A lonely house sits near those buildings.
改正：Near those buildings sits a lonely house.(错误)
小技巧：犹豫不决时选择单数。
