指的是谓语动词在人称和数上必须与主语保持一致。处理主谓一致问题，可依据三项原则：语法上一致、意义上一致和就近一致。根据这些原则，总结如下：
一.谓语动词用单数
(1)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，谓语动词一般要用单数动词。

(5)有些名词形式是复数，意义为单数，作主语时，要求单数动词。
例如：The chaos was stopped by the police.混乱被警察阻止了。

(7)某些不定代词，如：either,neither,each,one,other,another,anybody,anyone, anything,somebody,someone,something,everybody,everyone,everything,nobody,no one,nothing 等，当他们作主语时，其谓语动词通常用单数形式。

三.谓语动词可用单数也可以用复数
1.就近一致
有时谓语动词的人称和数与最近的主语保持一致，主要有以下两种情况：
(1)用连词either...or,neither...nor,whether...or,not only...but(also),or等连接的并列主语，如果一个是单数，一个是复数，则谓语动词按就近一致原则，与最靠近它的主语一致。
例如：What he does or what he says does not concern me.他做什么或是他说什么与我无关。

例如：Where is your mother and younger sisters?你的母亲和妹妹们在哪里?

(3)主语带有（together/along）with, such as, accompanied by, as well as, no less than, except, besides, with, combined with, in addition to , including, together with 等等附加成分，谓语的数不受附加成分的影响仍然与主语保持一致.如:
Professor Taylor , with six of his students ,is attending a conference in Boston organized to compare current practice in the United States with those of other nations. The president of the college, together with the deans, is planning a conference for the purpose of laying down certain regulations.
2.集体名词作主语时，谓语动词的数取决于主语表示的意思和数，当表示整体时候，谓语动词就用单数，当强调集体中的个体时候，谓语动词就用复数。这些集体名词如：army, audience, band ,government ,group ,flock, police, public ,staff ,team ,troop. Crowd, firm, family 等等
例如：The family is the basic unit of our society.家庭是社会的基本单元。

The audience were greatly moved at the words.听了这话听众都很感动。
3.一些表示数量的短语与名词连用时，谓语动词的数取决于名词的数。名词是复数，谓语动词用复数，反之就用单数。
这些短语有：a lot of(lots of),plenty of,a heap of (heaps of),half of,two thirds of,ninety percent of,part of,rest of,some of,none of等。
例如：Lots of damage was caused by the fire.火灾造成了很大的损失。

Each of us who are his classmates is willing to help him.我们这些他的同班同学都乐意帮助他。
5.代词的一致
代词一致是指句中代词应在数、性、人称等方面彼此保持一致，或者与它所照应的名词词组在某些方面保持一致。
例如：He is devoted to his aged mother.他全心全意地照顾他的年迈的母亲。
The city is proud of its parks.这座城市为它所拥有的公园而自豪。
You will be late for your appointment.你约会要迟到了。

(1) 由and连接两个先行词时，代词用复数。
例如：The tourist and businessmen lost their luggage in the accident.在事故中旅游者和商人丢失了行李。
(2) 由either...or,neither...nor,not only...but (also),or连接先行词，如果两个先行词在数和性上是一致的，就用其相应的一致的人称代词；如果两个先行词在数或性上不一致，人称代词一般与邻近的先行词在数、性上保持一致。
例如：Neither Mary nor Alice has her key with her.玛丽和爱丽丝都没带钥匙。
Neither the package nor the letters have reached their destination.包裹和信都未到达目的地。
Did Andrew or Alice lose herself confidence?是安德鲁还是艾丽斯失去了信心?

在正式语体中，如果两个先行词在性或数上不一致，则用两个不同的人称代词。如：
If either David or Janet comes,he or she will want a drink.
如果是大卫或珍妮特来，他或她是要喝点儿的。
(3) 当each,everyone,everybody,no one,none,nobody,anyone,anybody,someone,somebody 用作主语或主语的限定词时，其相应的代词一般按照语法一致原则，采取单数形式。
例如：Everybody talked at the top of his voice.每个人使劲扯着嗓门讲话。
None of the boys can do it,can he?没人能做这件事，他行吗?
Nobody wants to go there,does he?没人愿意去那儿，他愿意吗?
在非正式文体中，也可根据意义一致原则用复数代词。
例如：Everybody knows what they have to do.每个人都知道他们必须做什么。
(4) everything,anything,something,nothing之类的不定代词作主语时，句中相应的代词，一般只按语法一致的原则，用其单数的形式。
例如：Everything is ready,isn’t it?一切都准备好了，对吧?
Something strange happened,didn’t it?不是吗?某种奇怪的事情发生了。
(5) 当主语为复数形式，后跟each作同位语时，如果each位于动词之前，其后的代词或相应的限定词用复数形式；如果each位于动词之后，其后的代词或相应的限定词用单数形式。
例如：They each have two coats.他们每人两件外衣。
We are each responsible for his own family.我们各自负责自己的家
6.某些固定结构中主语与谓语的数：
