I．单数主语：

1．当 every-, some-, any-, no- 等构成的不定代词及 each, either, neither 作主语时，谓语动词为单数。 Someone has told me about it.

Neither of us likes the film.

2．当 every 或 each 位于两个由连接词连接的单数主语前，谓语动词用单数。（必记之要点！）

Each girl and boy has a nickname.

Every man and woman is welcome.

3．位于主谓之间的介词短语不影响谓语动词的数，谓语动词须和主语一致。常见介词短语有：in addition to, together with, as well as, along with, but, except, etc.

（这是一几乎所有考试都不愿放过的重点。）

The teacher along with his students is going to the party.

His parents as well as his elder sister have come to see him.

II．复数主语：

1．当主语由 and 或 both ... and 连接，通常采用复数谓语动词。

● Both thegirl and the boyare his friends.

2．如主语是both, few或主语前有both, few, several, many 等限定词时，谓语动词须用复数。 liuxuepaper.com
