在英语句子里，谓语受主语支配，其动词必须和主语在人称和数上保持一致，这就叫主谓一致。

1、 以单数名词或代词、动词不定式短语、动名词短语或从句做主语时，谓语动词一般用单

数形式；主语为复数时，谓语动词用复数形式。如：His father is working on the farm. To study English well is not easy. / What he said is very important for us all.

The children were in the classroom two hours ago. / Reading in the sun is bad for your eyes.

注：Δ由what引导的主语从句，后面的谓语动词多数情况用单数形式，但若表语是复数或what从句是一个带有复数意义的并列结构时，主句的谓语动词用复数形式。 如：What I bought were three English books. / What I say and do is (are) helpful to you.

2、 由连接词and或both … and连接起来的合成主语后面，要用复数形式的谓语动词。

…… 此处隐藏0字 ……

Lucy and Lily are twins. / She and I are classmates.

The boy and the girl were surprised when they heard the news.

Both she and he are Young Pioneers.

注：Δ① 若and所连接的两个词是指同一个人，物或同一概念时，它后面的谓语动词就应

用单数形式。如：The writer and artist has come.

Trial and error is the source of our knowledge.

② 由and连接的并列单数主语前如果分别有no, each, every ,many a等修饰时，其谓语动词要用单数形式。如：Every student and every teacher was in the room.. / No boy and no girl likes it.

3、主语为单数名词或代词，尽管后面跟有with, together with, except, but, like, as well as, rather than, more than, no less than, besides, including等引起的短语，谓语动词仍用单
