独立主格结构”是由名词或代词作为逻辑主语，加上分词、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， 通常称为“独立主格结构”。
独立主格结构的特点：
☞没有连接词，独立主格部分用“ ，”与主句分开。 ☞两个句子分别有自己的主语和谓语，即独立主格结构的逻辑主语与主 句 的主语不同。
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。
要求：可以使用连词，请将句子合并为复合句。 ☞ Because it rained yesterday, I stayed at home.
要求：不适用连词，将两个句子合并为一个句子。 ☞ It raining, I stayed at home.
比较三句：
☞ It rain so/and I stayed at home. ☞ Because it rained yesterday, I stayed at home. ☞ It raining, I stayed at home.
