现在分词作状语的用法

现在分词作状语：

①现在分词doing所代表的动作或状态与谓语动词是同时或几乎是同时发生的，可以作时间、原因、方式、条件、结果、目的、让步、伴随等状语。分词的逻辑主语就是句子的主语。如：

Rushing out of the house, he was knocked down by a car.

他一冲出屋子就被一辆车撞倒了。

②有些分词作状语，没有逻辑上的主语，已成为习惯用法：considering, judging from, talking of, allowing for(考虑到), generally/frankly/honestly/roughly/strictly speaking, assuming that(假设)等。如：

Talking of this film, it’s wonderful.

说到这部电影，好极了。

假定那是真的, 我们现在该怎麽办?
