(1)以單數(shù)名詞或代詞，動(dòng)詞不定式短語作主語時(shí)，謂語動(dòng)詞要用單數(shù);主語為復(fù)數(shù)時(shí)，謂語用復(fù)數(shù)，例如：

但并列主語如果指的是同一人，同一事物或同一概念，謂語動(dòng)詞用單數(shù)。例如：

The poet and writer has come.

(3)由and連接的并列單數(shù)主語之前如果分別由each,every修飾時(shí)，其謂語動(dòng)詞要用單數(shù)形式。例如：

Each man and each woman is asked to help.

(4)主語是單數(shù)時(shí)，盡管后面跟有but,except,besides,with等介詞短語，謂語動(dòng)詞仍用單數(shù)。例如：

The teacher with his students is going to visit the museum.

Nobody but two boys was late for class.

Bread and butter is a daily food in the west.

(5)一些只有復(fù)數(shù)形式的名詞，如people,police,cattle,clothes等作主語時(shí)，謂語動(dòng)詞要用復(fù)數(shù)。例如：

(7)有兩部分構(gòu)成的物體的名詞，如glasses,shoes,trousers,chopsticks,scissors等作主語時(shí)，謂語動(dòng)詞用復(fù)數(shù)。例如：

Your trousers are dirty.You’d better change them.

如果這類名詞前用了a pair of等，則往往用作單數(shù)，謂語動(dòng)詞的單復(fù)數(shù)形式往往取決于pair的單復(fù)數(shù)形式。例如：

Here are some new pairs of shoes.

My new pair of socks is on the bed.
