1、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。,主谓一致,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. Th
2、e 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：Luc
3、y 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. Going to bed early and getting up early is a good habit. （2）由and连接的并列单
4、数主语前如果分别有no， each， every more than a （an）/one ， 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
5、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 u

8、ority of + 名词”构成的短语以及由“分数或百分数+名词”构成的短语作主语，其谓语动词的数要根据短语中后面名词的数而定。 如：There are a lot of people in the classroom. The rest of the lecture is wonderful. 50% of the students in our class are girls. 注意：a number of“许多”，作定语修饰复数名词，谓语用复数；the number of“的数量”，主语是number，谓语用单数。,8. 在倒装句中，谓语动词的数应与其后的主语一致。 如：There co
9、mes the bus. On the wall are many pictures. Such is the result. Such are the facts.,二、逻辑意义一致原则 逻辑意义一致就是谓语动词的数必须和主语的意义一致（因有时主语形式为单数，但意义为复数；有时形式为复数，但意义为单数）。 1. what， who， which， any， more， all等代词可以是单数，也可是复数，主要靠意思来决定。 如：Which is your bag？ Which are your bags？ All is going well. All have gone to Beijing

I think physics isnt easy to study. 7. trousers，
12、glasses， clothes， shoes，jeans 等词作主语时，谓语用复数，但如果这些名词前有a （the） pair of等量词修饰时，谓语动词用单数。 如：My glasses are broken. The pair of shoes under the bed is his. 8. “定冠词the + 形容词或分词”，表示某一类人时，动词用复数。 9.aircraft，deer ， fish ，means ，species ，series ，works ，sheep 作主语时根据意义决定 如：The sheep is big. The sheep are eating gra

15、 ， not only but also连接时，谓语动词和邻近的主语一致。 如：Either the teacher or the students are our friends. Neither they nor he is wholly right. Is neither he nor they wholly right？,2. there be句型的be动词单复数取决于其后的主语。如果其后是由and连接的两个主语，则应与靠近的那个主语保持一致。 如：There are two chairs and a desk in the room. 注意：Here引导的句子用法同上。 如：Here
