主谓一致指的是句子的谓语动词与其主语在数上必必须保持一致。句子的主语是第三人称单数时其位语动词需用单数形大,主语是复数时、其谓语动词用复数形式。主谓一致要遵循三个基本最则、即语法一致、意义一致和就近一致。
语法一致
1. 单数主语+单数谓语;复数主语+复数谓语
句子的谓语动词与主语的中心词保持一致,不受主语修饰语的影响。
The manager is going to take a diner party tonight.
My wages are low, but my taxes are high.
2. 并列结构作主语
(1) and和both and连接的并列成分作主语
and, both... and连接的并列成分作主语.谓语动词通常用复数。但并列成分如果指同一个人、事物或者概念时,谓语动词要用单数形式。
Mr. Black and Mrs. Black have a son called Tom.
Both he and I are right.
(2)each..and each... , every..and every..及no...and no...类
此类结构作主语时,谓语动词用单数。
Each man and each woman is asked to help.
In our country every boy and every girl has the right to receive education.
No boy and no girl is admitted in.
3. 复数意义的集体名词作主语
表示复数意义的集体名词如people, police, cattle等作主语时,谓语动词总是用复数形式。
Many people make it a habit to take regular exercise.
Cattle provide us with milk and beef.
4. glasses/trousers/pants/shoes等+复数谓语
一些由两部分构成的名词作主语时,谓语动词通常用复数。
The trousers are all right. Now please try on the shirt.
My gloves are torn, so I need to buy a new pair.
5. A+with/along with/as well as等短语+B
主语后带有with, together with, as well as, no less than, along with等短语时,谓语动词不受这些短语的影响,仍然与主语保持致。
The teacher together with some students is visiting the factory.
He as well as I wants to go boating.
意义一致

(1)表示时间距离价值重量等的名词作主语

Two hours is too short for the visit. 两个小时的参观太短了。
(2) a number of/the number of +复数可数名词+复数谓语/单数谓语
“a number of ”复数可数名词表示“许多......”,作主语时,谓语动中用复数;the number of+复数可数名词表示“......的数目”。作主语时谓语动词用单数。
A number of cars are parked in front of my house. 许多小汽车停在我家门前。
The number of the students has increased recently. 学生的数目最近有所上升。
(3)数量词+of+单数可数名词/不可数名词/复数可数名词+单数谓语/复数谓语

2. 不定式动名词/从句作主语
不定式动名词或从句作主语谓语动词一般用单数形式,但and连接的两个或多个不定式动名词或从向作主语表示不同概念时,谓语动词用复数形式。

3. “the+形容词/分词” 作主语

就近一致
1. there be句型的就近一致

2.部分连词句型的主谓一致
