处理主谓一致一般有以下三条原则：
1、语法一致，即在语法形式上取得一致，例如主语为单数形式，谓语也用单数形式，主语用复数形式，谓语也用复数形式。
The number of mistakes was surprising.
Li Ping and her twin sister naturally look a lot alike.
2、意义一致，即从意义上着眼处理一致关系。例如，主语形式虽为单数但意义为复数，谓语动词也采取复数形式。
The crowed were fighting for their lives.
或者主语形式虽为复数但意义上视为单数，谓语动词也用单数形式。
Three years in a strange land see***ike a long time.
3、就近原则，即谓语动词的单复数取决于最靠近它的主语。
There is a teacher and some students in our classroom

【5】由some, any, no, every构成的复合代词，都作单数看待，因此谓动都采取单数形式。
Is everyone here?
There is nothing but a card in the box.
【6】如果主语由each(either, neither)+of+n复数或代词结构担任时，谓动采用单数
Has either of them told you?
Each of the Ss in our class likes reading.
【7】如果主语由“many a/ more than one +单数”构成，尽管从意义上看是复数，谓动仍采用单数。

【8】在“each …… and each” “`every ……and every” “No …… and no” 连接两个或两个以上的单数n等结构之后，谓语动词通常采用单数形式Each man and each woman was asked to help.


【9】如果主语是人名、国名、书名或组织机构名称时，即使是复数形式，谓动通常采用单数形式。

【10】成对的名词作主语时，谓语动词采用单数形式如：

复数
【1】有些指多数人或物的n（如people, police, cattle）单数形式，具有复数意义，谓动采用复数形式。
The police are looking for the lost boy.
【2】不可数n前面如有表数量的名词，后面常跟复数动词作谓语。

Three million tons of coal were exported last year.
【3】one or two +名复作主语，谓动采用复数形式。

【6】在It is +n或代词 +that/who …的强调句，谓语动词要与所强调的n或代词一致，如：

【8】两个主语用and连接时，谓动一般用复数

但当and连接的两个词是指一个观念或同一个人时，谓动v则用单数：

His end and aim is clear to all of us.
【9】集体n: group, class, family, enemy, team, army, crowd, company, government等作主语时，如果视为整体谓动就用单数，视为其中的个体成员，就用复数

由there或here引导的句子，主语不止一个，谓语v通常和邻近的那个主语一致。
