状语从句中的省略
在表示时间、地点、条件、方式(比较)或让步等的状语从句中,如果谓语动词含有动词be,主语又和主句的主语一致,或其主语是it,那么从句中的主语和谓语的一部分(尤其是be动词)往往可以省略。
(1)从属连词+名词

novels.

例句:When (he was) still was a boy of six, Bob was sent away from
home.

例句:He stared at me as if seeing me for the first time.

(8)其他形式
a)省略式的条件状语从句句型为if necessary、if possible、if true、if so、if not、if anyone、unless、once、as long as等词或短语后也运用省略形式。这种省略式的状语运用频繁,有的已经成了习惯表达法,被人们所熟知,而对于其完整的状语从句用的越来越少。

例句:If (it is) true, this will cause us a lot of trouble.
如果是真的,这会给我们带来很多麻烦。
b)状语从句中的主语尽管与主句的主语不同,但如果是根据主、从句的对应关系判断,意思比较明确,同时,从句的谓语又含有动词“be”的某种形式,则可省略从句中的“主语+be”部分
例句:There are a few simple safety measures to follow while (you
are) training.
