探究点3 动词-ing形式与过去分词作状语的区别
动词-ing形式与过去分词作状语的最主要的区别在于两者与其逻辑主语的主谓与动宾关系。
1.动词-ing形式作状语时,动词-ing形式的动作就是句子主语发出的动作,它们之间是逻辑上的主谓关系。动词-ing形式的动作与谓语动作同时发生用一般式doing;如果动词-ing形式的动作发生在谓语动作之前,表示已经完成,表示主动就用having done,表示被动就用having been done。
Walking along the street, I met a friend of mine.
沿着大街走时,我碰到了我的一个朋友。
Having finished their work,they went home to have a rest.
完成工作后,他们回家休息了。
2.过去分词作状语时,过去分词表示的动作是句子主语承受的动作,它们之间的关系是逻辑上的动宾关系。
Given more attention,the tree could have grown better.
如果给予更多的关注,小树本来能够长得更好一些。
Grown in rich soil, these seeds can grow fast.
