谓语受主语支配，须和主语在人称、数上保持一致，叫主谓一致。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。

由and连接的并列单数主语的前边如果分别有each, every, 或no修饰时，其谓语要用单数形式
例：In our country every boy and every girl has the right to education.
No teacher and no student is going to take part in such a boring game.

主语是单数，其后尽管有as well as, no less than, rather than, more than, but, except, besides, with, along with, together with, like, including, in addition to等起连接作用的词语带其他名词，谓语动词仍用单数。

某些不定代词，如either, neither, each, one, the other, another, anybody, anyone, anything, somebody, someone, something, every body, every one, everything, nobody, no one, nothing.等，当它们作主语时，通常用单数。

many a +单名，谓语用单数。
例：Many a student is coming.

the number of+复数名词，谓语用单数，中心词是number

以ics结尾的学科名称，如mathematics, physics, politics, news, works等都属形复意单名词，谓语用单数。
例：Mathematics seems to be difficult to me.
The glass works was rebuilt in 1959.

用作书名、剧名、报纸名、国名等复数名词作主语时，谓语用单数。
例： “The Arabian Nights” is a very interesting story book.
The United States is a capitalist country.

主语为复数，谓语用复数。
例：They are doing their homework now.

用and或both… and连接并列主语时，谓语用复数。
例：Plastics and rubber never rot.
He and I are classmates when we were at college.
Both bread and butter were sold out in that shop.
What he says and what he does do not agree.
但是：并列主语如果指的是同一人、同一事物或同一概念其谓语要用单数形式，这时and后面的名词没有冠词。
例： In this hotel, the bread and butter (= the bread with butter on it) is served for breakfast.
A cart and horse was seen in the distance.
The girl’s teacher and friend is a young doctor.
Truth and honesty is the best policy.

一些只有复数形式的名词如clothes, scissors, trousers, shorts, scales, glasses等，它们作主语时，谓语要用复数。
例：The scales are mine.
My trousers are being washed.
但：如果成双的东西前有a pair of来修饰时，谓语要用单数。
例：This pair of scissors belongs to the tailor.

表总称意义的名词public, police, cattle, people（人们、人民）作主语时，谓语动词用复数。
例：The police have not made any arrests.
People are talking about the news.
