主谓一致

1、以单数名词或代词、动词不定式短语作主语时，谓语动词要用单数;主语为复数时，谓语用复数。

2、由and或both……and连接的并列成分作主语时，谓语动词用复数

但并列主语如果指的是同一人、同一事物或同一概念，谓语动词用单数。例如：

The poet and writer has come.

3、一些只有复数形式的名词，如people, police, cattle, clothes等作主语时，谓语动词要用复数。

4、集体名词family, class, team, group 等看作整体时，谓语动词用单数;看作每一个成员时，谓语动词用复数。

5、表时间、距离、价格、度量衡等的名词作主语时，谓语动词通常用单数。

6、由连词not……but……, or, either……or, neither……nor, not only…but also,等连接的并列主语，如果一个是单数，一个是复数，则谓语动词按就近一致原则，与最靠近它的主语一致。

7、There be句型、以here,there开头的句子,谓语动词和靠近的主语一致。

8、 many a +单数名词 (许多……) ;作主语，尽管意思是复数，但谓语动词还是用单数。

Many a ship has been damaged in the storm.

考查主谓一致的常见题型有单项选择，完型填空。做这类题时，必须找出句子的真正主语，然后根据记忆的知识作出判断。同时，要遵循三个原则：语法一致、意义一致和就近原则。
