3. 使用- ing形式需注意的几个 问题。 分词 (短语) 作状语时, 其逻辑主语必 须与句子的主语一致。如果不一致， 必须用独立主格结构来表示，也就是 在分词前面加上它的逻辑主语。

My wife had a long talk with Sally, explaining why she didn’t want the children to play together. 我妻子与莎莉谈了很长时间, 解释 她为什么不想让孩子们在一起玩。

(现在分词explaining是句子主语my wife 做的动作,它们之间是主动关系, 即 explaining的逻辑主语

,就是句子的主 语my wife 。) The train having gone, we had to wait another day.(the train逻辑主语 + having gone 即为独立主格结构)

分词短语做状语时，前面可以加上连词 或介词，但是分词短语和句子之间不能 用并列连词(如but,and),因为并列连 词接的是两个并列成分，而分词短语只 是全句的一个状语部分，分词和主句之 间可用逗号。

例如: 误: Having been told many times, but he still couldn’t understand it. 正: He was told many times, but he still couldn’t understand it. 或 Having been told many times, he still couldn’t understand it.
