1、主谓一致谓语受主语支配，须和主语在人称和数上保持一致，这叫做主谓一致。主谓一致一般遵循三条原则：语法一致原则，意义一致原则和就近一致原则。在英语中，谓语动词必须和主语在人称和数上同主语保持一致，叫做主谓一致。通常采用下列三个原则来处理，即：语法形式一致的原则、逻辑意义一致的原则、就近（或毗邻）一致的原则。一、语法形式一致的原则，即在语法形式上取得一致。如：主语为单数形式，谓语动词用单数；主语为复数形式，谓语动词也采用复数形式。但须注意下列几种情况：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，谓语动词用单数。 例如： Much land has been deserted i

4、动。He and I were classmates when we were at college.他和我在上大学时是同学。Both John and Ann have got pen-friends.约翰和安都有笔友。Both Zhou Lan and Yang Pei like sports.周兰和杨蓓都爱好体育。注意1）但是，并列主语如果表示同一个人、同一事物或同一概念时，谓语动词用单数形式（这时and后的名词前没有冠词）。例如：The manager and secretary was absent at the meeting.经理兼书记没有出席会议。The manager and
5、 the secretary are busy now.经理和书记现在都很忙。Their teacher and friend is Mr. Li.他们的老师和朋友是李先生。2)由and连接的并列单数主语前如果分别被no, each, every或many a ，more than one修饰时，其谓语动词用单数形式。 例如：In our country every boy and every girl has the right to receive education.在我们国家里，每个男孩和女孩都有权利受教育。Each man and each woman is asked to hel

10、one 以及由none/either/neitherof复数合词(或代词)构成的短语作主语时，谓语用单复数均可，这取决于说话人的意思。当说话人着眼于“每一个都不.”或“两个中的任何一个都不.”时，谓语动词用单数；当说话者着眼于“所有的都不.”或“两个中的全部都不.”时，谓语动词用复数。例如： None know when that was.

28、n film True Lies was directed by a world-famous director.美国影片真实的谎言是由一位世界著名的导演导演的。7、如果主语由“the+形容词（分词）”担任时，往往根据意义一致原则，来决定谓语动词的单、复数形式。如果表示一类人时，谓语动用复数形式；如果指个人或抽象概念时，则谓语动词用单数形式。例如：The old is taken good care of in our country. 在我们国家老人受到很好的照顾。The sick is one of the students in our class. 那位病人是我们班的一个学生。The
29、beautiful lives forever. 美是永存的。8、名词所有格之后的名词被省略的情况，一般只指商店、公共建筑物、住宅等，作主语时，谓语动词一般用单数。例如：The bakers is on the side of the street.理发馆在街道的另一边。My uncles is not very far from here.我叔叔的家离这儿不太远。9、数词作主语时，谓语用单数，但有四则运算中，谓语单、复数均可。如：Ten is a round number. 十是个整数。Ten times five is / are fifty. 十乘五等于五十。Three hundred
30、and forty plus six hundred and sixty is / are one thousand.340 加660等于1000。10.疑问代词who, what, which作主语时，谓语动词的形式取决于它产本身的含义。如： Who teaches you English? 谁教你们英语?Who have gone there? 谁都已经去那儿了?Which is your room? 哪一间是你的房子?Which are your rooms? 哪几间是你的房子?11、表示数量的短语“one and a half名词复数”及“a单数名词anda half”作主语时，谓语用
