主谓一致详细讲解

1）某些集体名词，如family, team等作主语时，如果作为一个整体看待，谓语动词用单数形式，如果就其中一个个成员而言，谓语动词用复数形式。如：
His family is a happy one.
The whole family are watching TV.
这类名词有：audience，class，club，company，crew，enemy，crowd，government，group，party，public，team等。
2）某些集体名词，如people, police, cattle等，只当复数看待，谓语动词必须用复数。如：
The police are searching for the thief.
3）单、复数同形的名词主语时，谓语动词应根据意义决定单、复数。如：
A sheep is over there.
Some sheep are over there.
4）当名词词组中心词为表示度量、距离、金额、时间、书名等复数名词时，往往可以根据意义一致的原则，把这些复数名词看作一个整体，谓语用单数形式。如：
Three years has passed since then.
5）不定代词each, every, no所修饰的名词即使以and或逗号连接成多主语时，谓语动词仍用单数形式。如：
Each boy and each girl wants to go to the cinema.
6）如果主语有more than one很多 非常…或many a许多……构成，尽管从意义上看是复数内容，但它的谓语动词仍用单数形式。如：
More than one student has read the book.
Many a girl has been there.
但是，“more +复数名词+than one”结构之后，谓语动词一般多用复数形式。如：
More members than one are against your plan.
7）一些有两个部分构成的名词表示衣物或工具作主语时，谓语动词通常用复数形式，例如：glasses, clothes, trousers, shoes, compasses, chopsticks, scissors等。但如果主语用“a kind of, a pair of , a series of等加名词”构成时，谓语动词一般用单数形式。如：
A pair of shoes was on the desk.
8）this kind of book =a book of this kind（这种书），其谓语动词用单数；短语this kind of men =men of this kind =these kind of men(口语)（这一类人），但this kind of men的谓语动词用单数，men of this kind和these kind of men的谓语动词用复数，all kinds of后跟复数名词，谓语动词用复数形式。如：
This kind of men is dangerous.
Men of this kind are dangerous.
