文档介绍: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。主谓一致一般遵循语法一致、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 sister is working in the office. / To study English well is not easy. / What he said is very important to us all. / The people were in the stadium three hours ago. / Reading in bed 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 some apples, a few oranges and many pears. / 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:Jack and Tom are brothers. / The boy and the girl were surprised when they heard the news. / Both she and he are doctors.
 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 artist 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 boy and every girl was in the room. / No man and no woman 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,谓语动词仍用单数形式;若主语为复数,谓语用复数形式。如:Mr. Peter, together with his wife and children, has come to China. / Nobody but Jim and Mike was on the playground. / He, like you and Tom, is very handsome.
 4. either, neither, each, every 或no +单数名词和由some, any, no, every构成的复合不定代词,都作单数看待。如:Each
