一、就近一致原則
1.由or，not only...but also...，neither...nor...，either...or...，whether...or...，not...but...等連接兩個或兩個以上的并列主語時，通常根據(jù)就近一致原則，謂語動詞要與離它最近的主語在數(shù)上保持一致。

2.here/there引導(dǎo)一個句子而主語又不止一個時，通常根據(jù)就近原則，謂語動詞要與離它最近的主語在數(shù)上保持一致。

(2)表示某些組織機(jī)構(gòu)的名詞、書/報名、國名、地名等作主語時，雖然形式上是復(fù)數(shù)，但所表示的意義是單數(shù)，所以謂語動詞用單數(shù)。

(1)集體名詞，如family，class，group，team，club，company，government，population等作主語時，謂語動詞的形式根據(jù)其在語境中表示的意義而定。當(dāng)其表示集體意義，強(qiáng)調(diào)整體概念時，謂語動詞用單數(shù);當(dāng)其表示集體中各個組成部分，強(qiáng)調(diào)個體概念時，謂語動詞用復(fù)數(shù)。

(2)“the+形容詞/分詞”表示“一類人”時，謂語動詞用復(fù)數(shù)。

三、語法一致原則
