分词的独立结构是由逻辑主语和+分词构成,可以表示时间,条件,方式或伴随状况,那么下面这两个句子转换成状语从句是什么?1.She walked along the path,her daughters following close behind.2.He returned three days later,his face covered with mud.

1.She walked along the path,her daughters following close behind.
She walked along the path while her daughters were following close behind.(时间状语从句)
2.He returned three days later,his face covered with mud.
He returned three days later with his face covered with mud.(伴随状语)
在分词作状语时,其逻辑主语一般应与句子的主语一致.如果不一致的话,分词前面可以带有自己的逻辑主语(名词或代词),构成分词的独立结构(或称为带逻辑主语的分词结构).分词独立结构可表示伴随情况、陪衬动作、附加说明以及表示时间、原因、条件等.
【例如】
The moon has no light of its own,only sunlight shining on it.
(附加说明)
She rushed out the room,the little baby carried in her arms.
(伴随动作)
Maggie ran back to the kitchen,eggs held carefully in her hand.
(伴随动作)
They being blind men,how could they see the elephants?( =As they were blind men...)
(表示原因)
Circumstances changed,it is necessary for you to make a new plan.
(表示原因)
A force acting through a distance,work is done.(表示条件)
Both bright side and dark side considered,you will have the confidence to overcome this difficulty.(表示条件)
All flightsshavingsbeen cancelled because of the snowstorm,many passengers could do nothing but take the train.
there be句型和it也能引出分词独立结构,作状语修饰主句,there和it相当于分词的逻辑主语.
