1. 分词短语作状语时,若分词的逻辑主语与句子的主语不一致,分词前须加上自己的逻辑主语(名词或主格代词),这个结构叫分词的独立主格结构。如:
Supper finished (=After supper was finished), we started to discuss the picnic. 吃完晚饭,我们开始讨论野餐的事。
All things considered(If all things are considered), your article is of greater value than hers. 全面考虑起来,你的文章比她的文章更有价值。
2.“There being+主语”也是分词独立主格结构的一种。例如:
There being no danger, the police went back to their police office. 既然没有危险,警察们又回到警察局。
There having been no rain, the crops were dying. 因为没有下雨,庄稼就要旱死了。
3. 分词独立主格结构有时可以改成“with+名词词组+分词”结构。如:
The problem settled(= With the problem settled), they were happy and relaxed. 问题解决了,他们又高兴又轻松。
4. 有些惯用的分词短语在句子里可以没有逻辑上的主语而独立存在,它们往往作为句子的独立成分来修饰全句。如:
generally/strictly/roughly/broadly/narrowly speaking, judging from/by, considering, supposing, providing, provided等。如:
Talking of the computer, I like it very much.谈到电脑,我非常喜欢。
Considering the time, we have decided to start early tomorrow morning.考虑到时间,我们已经决定明早一早出发。
