高中语法复习二、主谓一致
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。

寻其规律，大致可归纳为三个原则，即语法一致、逻辑意义
一致和就近一致原则。

（一）语法一致原则：语法上一致就是谓语动词和主语在单、复数形式上保持
一致。

1、以单数名词或代词、动词不定式短语、动名词短语或从句作主语时，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 .
注意：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。

如： 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 .
注意：① 若 and 所连接的两个词是指同一个人或物时，它后面的谓语动词就
应用单数形式。

如： The writer and ar tist has come .; / ② 由 and 连接的并列单数主语前如果分别有 no , each , every more than a ( an ) , many a ( an )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 .。
