主谓一致的核心考点
1.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,即谓语动词要与离它最近的主语在数上保持一致。
Neither his parents nor I am able to persuade him to change his mind.
(2)here/there引导一个句子而主语又不止一个时,通常根据“就近一致”原则,即谓语动词要与离它最近的主语在数上保持一致。
Here is a ruler,a few pencils and two copybooks.
2.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,谓语动词用单数。
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。
