1．a(chǎn)nd連接的二個名詞作主語時，主語與謂語動詞的一致
一般情況下，and連接的兩個名詞作主語時，謂語動詞用復(fù)數(shù)形式。但有些情況下，and連接的兩個名詞意指同一人物、同一事物、同一概念時，謂語動詞要用單數(shù)形式。通常，如果兩個名詞只有一個限定詞或無限定詞修飾時，它們常常表示一個概念，如果兩個名詞分別有兩個限定詞修飾時，它們往往表示兩個不同的概念。另外，如果and連接的兩個單數(shù)名詞均有each, every, many a, no等詞修飾時，謂語動詞用單數(shù)形式。例如：
War and peace is a constant theme in history.
The wear and tear on the machine is obvious.
The secretary and manager was present at the meeting.
Every hour and every minute is vital to me now.
Many a boy and many a girl has been to the exhibition.
2．連詞or等連續(xù)兩個名詞（或代詞）作主語時，主語與謂語動詞的一致
連詞or, either…or…, neither…nor…, not only…but also…連接兩個名詞或代詞作主語時，謂語動詞必須和靠它較近的一個名詞或代詞取得一致，這就是就近一致原則。例如：
Either I or they are responsible for it.
Neither your unkind words nor you unfriendly attitude has caused me any distress.
Not only he but also his family members are interested in football match.
3． none本身作主語時或它修飾的名詞或代詞作主語時，如代表不可數(shù)名詞，謂語動詞用單數(shù)形式，如代表可數(shù)名詞，謂語動詞既可用單數(shù)形式也可用復(fù)數(shù)形式。
4．one and a half 后接的名詞應(yīng)是復(fù)數(shù)形式，但謂語動詞用單數(shù)形式。如：
One and a half years has passed.
5． more than one 后接單數(shù)可數(shù)名詞作主語時，謂語動詞用單數(shù)形式，但如果more than one本身作主語，謂語動詞則用復(fù)數(shù)形式。
6．either, neither作主語時，謂語動詞用單數(shù)形式。
7．one or two后接復(fù)數(shù)名詞作主語時，謂語動詞用復(fù)數(shù)形式。
8．one of后接復(fù)數(shù)名詞作主語時，謂語動詞用單數(shù)形式。
9．動詞不定式、動名詞短語、名詞性從句等作主語時，謂語動詞用單數(shù)形式。例如：
Seeing is believing.
