一、就近一致原则
1.由or，not only...but also...，neither...nor...，either...or...，whether...or...，not...but...等连接两个或两个以上的并列主语时，通常根据就近一致原则，谓语动词要与离它最近的主语在数上保持一致。

2.here/there引导一个句子而主语又不止一个时，通常根据就近原则，谓语动词要与离它最近的主语在数上保持一致。

二、意义一致原则
1.谓语动词必须用单数的情况
(1)表示学科的名词以及works(工厂)，news(消息)等作主语时，虽然本身为复数形式，但表示单数意义时，谓语动词仍用单数。
Politics is his favorite subject.
(2)表示某些组织机构的名词、书/报名、国名、地名等作主语时，虽然形式上是复数，但所表示的意义是单数，所以谓语动词用单数。

2.谓语动词必须用复数的情况
表示总称意义的名词，如people，police，public，cattle等作主语时，谓语动词用复数。

3.谓语动词的形式依据主语表示的意义而定
(1)集体名词，如family，class，group，team，club，company，government，population等作主语时，谓语动词的形式根据其在语境中表示的意义而定。当其表示集体意义，强调整体概念时，谓语动词用单数;当其表示集体中各个组成部分，强调个体概念时，谓语动词用复数。
As far as I know，his family is not very large but the family are all music lovers.
(2)“the+形容词/分词”表示“一类人”时，谓语动词用复数。

2.表示时间、数量、长度及价格的名词，尽管有时是复数形式但常被看作是一个整体，谓语动词用单数形式。
Is fifty pounds enough?
3.“分数/百分数+of+名词”作主语时，谓语动词的形式根据of后的名词的形式来定，如果名词是可数名词复数，谓语动词用复数形式;如果名词是单数可数名词或不可数名词，谓语动词用单数形式。
