英语句子中，主语的“人称”和“数”要限制、决定谓语动词的形式变化，这就叫“主谓一致”关系。它通常依据三项原则：1）语法一致；2）意义一致；3）就近一致主谓一致主要有以下几种情况： 语法一致是指句子的主语和谓语在语法形式上一致，即谓语动词的单复数形式依主语的单复数形式而定。主语为单数时谓语动词用单数，主语为复数时谓语动词也用复数。语法一致原则1. and连接两个或两个以上单数名词或者代词作主语的时候, 谓语动词有以下两种情况：
(1)如果指两个或两个以上不同的人或事物的时候, 谓语动词用复数。
He and I ____ both students of this school. 我和他都是这个学校的学生。 areThe singer and dancer _____ on the stage.is(2) 如果连接两个以上的名词指的是同一个人或物, 或者指同一概念的时候, 谓语要用单数。 2. 如果主语是不定式，动词ing形式或主语从句的时候,谓语动词用单数。
　他正在做的事情看起来很重要。
What he is doing seems very important.
收集邮票是他的爱好。
Collecting stamps is his hobby. 3、当主语后面跟有as well as, as much as, no less than, along with, with ,like, rather than, together with , but ,except, besides, ,including等引导的词组时，其谓语动词的单、复数由主语的单、复数而定。1）The teacher with two students ______ at the meeting . (was / were)
was2）E-mail, as well as the telephones, ________ an important
part in daily communication.A. is playing B. have played
C. are playing D. play A4. 用连接的并列主语被each, every, no或 many a 修饰时，谓语动词 用单数。
Every desk and every chair is made of wood.
Many a boy and (many a ) girl has made the same mistake. 邻近一致是指谓语动词的人称和数与它最邻近的名词或代词保持一致。
either ... or; neither ... nor; not only ... but also, whether...or在句子中连接主语的时候或者在there be句型中, 谓语动词要和就近的主语保持一致。就近原则　 Not only the students but also the teacher wishes for a holiday. Neither you nor I am wrong.
There is a cup of tea and some apples
on the table. 所谓概念一致原则是指谓语动词和主语一致不是取决于主语的语法形式, 而是其实际意义。有的主语名词在形式上是单数, 但在意义上却是复数；有的主语名词在形式上是复数, 但在意义上却是单数。概念一致原则1. 不定代词all, more, some, any, none作主语, 谓语动词视情况而定。All of the apples ____ rotten.
