1、独立主格结构I. 独立主格结构的基本概念由一个名词或代词作为逻辑主语,加上一个分词、形容词、副词、动词不定式或介词短语作为逻辑谓语构成,这种结构在形式上与主句没有关系,通常被称为独立主格结构。II. 独立主格结构的基本构成形式及功能独立主格结构主要起状语作用,相当于一个状语从句,多用来表示行为、方式、伴随等情况,有时也可用来表示时间、原因、条件等情况。1、名词或代词主格 + 分词The experiment done, the students went on to take notes in the experiment report. 实验做完了,同学们继续在实验报告上做记录。Time p
