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(gè)或兩個(gè)以上的并列主語(yǔ)時(shí)，通常根據(jù)就近一致原則，謂語(yǔ)動(dòng)詞要與離它最近的主語(yǔ)在數(shù)上保持一致。

二、意義一致原則
1.謂語(yǔ)動(dòng)詞必須用單數(shù)的情況
(1)表示學(xué)科的名詞以及works(工廠)，news(消息)等作主語(yǔ)時(shí)，雖然本身為復(fù)數(shù)形式，但表示單數(shù)意義時(shí)，謂語(yǔ)動(dòng)詞仍用單數(shù)。

2.謂語(yǔ)動(dòng)詞必須用復(fù)數(shù)的情況

(1)集體名詞，如family，class，group，team，club，company，government，population等作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞的形式根據(jù)其在語(yǔ)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(shí)，謂語(yǔ)動(dòng)詞用單數(shù);當(dāng)其表示集體中各個(gè)組成部分，強(qiáng)調(diào)個(gè)體概念時(shí)，謂語(yǔ)動(dòng)詞用復(fù)數(shù)。

三、語(yǔ)法一致原則

2.表示時(shí)間、數(shù)量、長(zhǎng)度及價(jià)格的名詞，盡管有時(shí)是復(fù)數(shù)形式但常被看作是一個(gè)整體，謂語(yǔ)動(dòng)詞用單數(shù)形式。
Is fifty pounds enough?
3.“分?jǐn)?shù)/百分?jǐn)?shù)+of+名詞”作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞的形式根據(jù)of后的名詞的形式來(lái)定，如果名詞是可數(shù)名詞復(fù)數(shù)，謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式;如果名詞是單數(shù)可數(shù)名詞或不可數(shù)名詞，謂語(yǔ)動(dòng)詞用單數(shù)形式。
