主谓一致讲解和练习

Subject-Verb Agreement 主谓一致

**主谓一致是指谓语在人称和数上必须和主语的人称和数保持一致。 主谓一致有三大原则：

主语为单数形式，谓语动词也用单数形式；主语为复数形式，谓语动词也用复数形式。 1. and连接两个或两个以上单数名词或者代词作主语的时候,谓语动词有以下两种情况： He and I are students of this school. e.g.: The singer and dancer is going to give us a performance. ** 比较一下

The singer and dancer _is_ (be) going to give us a performance.

The singer and the dancer _are_ (be) going to give us a performance.

e.g.: The knife and fork is on the table.

A).表整体概念的并列结构：

bread and butter 黄油面包 knife and fork 刀叉 iron and steel 钢铁 law and order 治安 B).配套事物：

a watch and chain 一块带链的手表 a cart and horse 马车

a coat and tie 一件带领带的外套 a needle and thread 针线 2. 如果主语是不定式, 动词ing形式或主语从句的时候,谓语动词用单数。

What he is doing seems very important. Collecting stamps is his hobby.

To learn a foreign language well is not a difficult task. 3. 定语从句的关系代词who, which, that在从句中作主语时，要与先行词的人称和数保持一致。 Those who enjoy singing may join us. Tom, who is your friend, should help you.

4. with, along with, together with, as well as, besides, like, without, except, but, including, rather

than 如果句子中有这些连接词和主语连用,谓语动词的数随主语的变化而变化。 The teacher, together with his students, is planting trees in the street.

is_ (be) at school. 即谓语动词的单复数形式取决于最靠近它的主语。

1. 用连词or, either…or, neither…nor, not only…but also等连接并列主语时，谓语动词应与最近的主语保持一致。

Neither you nor I __am__wrong. (be) Neither I nor you __are__ wrong. (be)

Not only the students but also the teacher __enjoys_____ listening to the music. (enjoy) Not only the teacher but also the students ___enjoy___ listening to the music. (enjoy) 2. 由here, there等引导的倒装句中，若主语不止一个时，谓语动词与最近的主语保持一致。 Here comes the bus.

Here is a pen and two books for you. Here are two books and a pen for you.

3. 在表存在的there be 句式中，主语是两个或多个并列名词（短语），be的形式与最近的一个名词（短语）保持一致
