1.表示并列關(guān)系的連詞有：and，both…and…，not only… but also…和neither…nor…

1)and的特別用法：

祈使句后連接and，有條件句作用，此時and=if you…，you'll…

謂語動詞一般用復(fù)數(shù)。

3)neither…nor…：既不…也不…

neither…nor…連接兩個并列主語時，謂語動詞靠近哪個主語就與哪個主語保持“人稱”和“數(shù)”的一致，即采取就近原則。Neither I nor he has seen the play before.

4)not only…but also…：不但…而且…

not only…but also…連接兩個主語后的謂語動詞也遵循就近原則。

Not only the mother but also the children are ill.

2)either…or…：或者…或者…;不是…就是…;要么…要么…
