过去分词短语作状语相当于一个状语从句。上句中过去分词作条件状语可以和条件状语从句转换，条件状语从句的主语与主句的主语一致的情况下，可去掉连词及从句的主语，如是被动语态，只保留过去分词作状语，在过去分词前无需有being。

Considered from this point of view, the question will be of great importance.

= If it is considered from this point of view, the question will be of great importance.

例1 If we are given more time, we'll do the work better.

作这类状语的分词有时前面可加连词if/unless。

= He will not come to the lecture unless invited.

例3 _____ from the top of the hill, the lake is just like a mirror. (时间状语)
