悬垂结构是怎么回事?

悬垂结构是怎么回事?

如果分词的逻辑主语既不是所在句子中的主语或宾语,又不是独立主格结构,那就成了“垂悬分词”,是一种病句,应该避免.
比较:
我们站在海岸上,看到船在远处航行.
Standing on the seashore,the ship was sailing in the distance.(误)
(standing的逻辑主语不可能是the ship)
Standing on the seashore,we saw the ship sailing in the distance.(正)
Being very wide,we can't swim across the river.(误)(being的逻辑主语不可能是we)
The river being very wide,we can't swim across it.(正)河很宽,我们游不过去.
