         独立主格结构是由名词或代词加上其他成分(分词、不定式、名词、代词、形容词、副词或介词短语)构成。        

 

特点

 

在语法上是一个独立的短语,不是句子,在意思上依附于整个句子,具有以下特点:

 

1、独立主格结构的作用相当于状语从句。可表示时间、原因、条件、行为或者伴随情况。

 

2、独立主格结构可置于句首,也可以放在句尾。

 

3、独立主格主要用于书面语。4独立主格结构的逻辑主语与语法主语不同,不能指同一个人或者同一事物。

 

若名词/代词与非谓语构成主动关系,用doing或having done;若名词/代词与非谓语构成被动关系,用done或having been done。having done与having been done 强调非谓语发生在主句谓语之前。
