语法复习二、主谓一致

发布时间:2019-11-09

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 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 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,谓语动词仍用单数形式;若主语为复数,谓语用复数形式。如:mr green, together with his wife and children, has come to china. / nobody but jim and mike was on the playground. / she, like you and tom, is very tall.
 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 of us has a new book. / everything around us is matter.
 注意:① 在口语中当either或neither后跟有“of+复数名词(或代词)”作主语时,其谓语动词也可用复数。如:neither of the texts is (are) interesting. ② 若none of后面的名词是不可数名词,它的谓语动词就要用单数;若它后面的名词是复数,它的谓语动词用单数或复数都可以。如:none of us has (have) been to america.
 5、在定语从句时,关系代词that, who, which等作主语时,其谓语动词的数应与句中先行词的数一致。如:he is one of my friends who are working hard. / he is the only one of my friends who is working hard.
 6、如果集体名词指的是整个集体,它的谓语动词用单数;如果它指集体的成员,其谓语动词就用复数形式。这些词有family, class, crowd, committee, population, audience等。如:class four is on the third floor. / class four are unable to agree upon a monitor.
