一、词语用法：

conj. (连词)

1、unless所引导的条件状语从句常用一般现在时表示将来意义,主句多用一般将来时。

unless在表示“除非”时,如其引导的从句谓语是be,而从句的主语跟主句的主语相同时,从句的主语和be就可省略。有时从句中主语为it时,也可省略it或从句中的有关成分。

2、在unless引导的肯定形式的条件从句中通常用肯定词,如:already, still, some, too。在unless引导的否定形式的条件从句中通常用否定词。

3、unless表示条件时后可接现在分词短语。

二、词汇搭配：

1、unless and until 直到 ... 才

2、unless otherwise stated 除非另作说明...

3、unless otherwise specified 除非另作说明，如无特...

三、词义辨析：

conj. (连词)

二者均可表示“如果不…”。unless不可引导虚拟语气从句; if...not...可用于虚拟语气结构。
