主谓一致

一、主谓一致及其意义
英语句子的主要组成部分是主语和谓语, 其中谓语动词是其核心。谓语动词在人称和数上要跟主语保持一致, 即主谓一致。主谓一致一般遵循以下三个原则:
(一)语法一致原则,即谓语动词同主语在单复数形式上保持一致。如:
She is a clever girl.
We come from Dongying.
He goes to school on foot every day.

(二)概念一致原则,即谓语动词的单复数取决于主语表达的概念。如:
My family are all well.
Bread and milk are both good for our health.
(三)就近原则,即谓语动词的单复数与最靠近它的主语保持一致。如:
Either you or I am right.
Neither we nor she comes on time.

(四) 动名词、动词不定时或从句作主语时,谓语动词用单数。如:
Watching TV too much is bad for our eyes.
To give is better than to receive.
That they didn’t go there is a pity. (一般用it 作形式主语)
(五) 表示时间、金钱、度量、重量、距离等的复数名词作主语时,通常看作整体,谓语动词用单数。如:
Two months is quite a long time。
Five dollars isn’t enough to pay for the book.
Five thousand kilometers is a long way.

The speaker and writer is going to give us a talk tomorrow.
A fork and knife is on the table.
(七)用and 连接的单数主语前有each,every,no等修饰时,谓语动词用单数。如:

Twenty minus three is seventeen.
Forty divided by eighty is two.
(九)none of 跟可数名词作主语时,谓语动词可以用单数,也可以用复数;most of,half of,some of,a lot of,part of,the rest of或分数等作主语时,谓语动词与of后的名词、代词的数保持一致。如:
None of us has/have heard from them.
Some of the workers are making machines.
Two thirds of the teachers are women.

(十一)有些名词如people,police,public(民众),cattle(牛,牲畜)等形式上是单数,意义上却是复数,故谓语动词用复数形式;而有些名词,如politics,maths,physics,news等形式上是复数,实为单数或不可数名词,其谓语动词用单数。如:
Maths is more difficult than Chinese.
The police are searching for the robber.
No news is good news.
