英语独立主格是个怎么回事呢?
英语独立主格是个怎么回事呢?
“独立主格结构”在句中的功能就相当于一个带有自己主语的非限制性状语从句.众所周知非限制性从句通常以主句的某一成分作为自己的逻辑主语,从而依附于主句.而有些非限制性从句和无动词从句带有自己的主语,在结构上与主句不发生关系,因此成为独立主格结构.其实,虽然叫做独立主格结构,并不是真正的独立,它还是一种从属分句,在句中有多种作用.如:表原因、表条件、表方式、表伴随、表时间等,在句中通常起状语作用.有时还可以做定语 .
  独立主格结构主要用于描绘性文字中,其作用相当于一个状语从句,常用来表示时间、原因、条件、行为方式或伴随情况等.例如:
  1) 表示时间
  The meeting being over,all of us went home.开完会后我们都回家了.the meeting being over相当于when the meeting was over
  Her work done,she sat down for a cup of tea.她干完了活,坐下来喝茶.her work done相当于when her work was done
  2) 表示条件
  The condition being favorable,he may succeed.若条件有利,他或许能成功.If the condition is favorable
  3) 表示原因
  There being no taxis,we had to walk.没有出租车,我们只好步行.Since there was no taxis,
  He wrapped her up with great care,the night being dark and frosty.夜又黑又冷,所以他把她裹得严严实实的.as the night was dark and frosty
  4) 表示伴随情况  
Almost all metals are good conductors,silver being the best of all.几乎所有的金属都是良导体,而银则是最好的导体.(=Almost all metals are good conductors,and silver is the best of all.)
  5) 表示补充说明
  We redoubled our efforts,each man working like two.我们加倍努力,一个人干两个人的活.
  *注:独立主格结构表示时间、条件或原因时,相当于一个状语从句,一般放在句首,表示原因时还可放在句末;表伴随状况或补充说明时,相当于一个并列句,通常放于句末.
