独立主格结构
一、什么是独立主格结构？
一种说法：由一个相当于主语的名词或代词加上非谓语动词、
形容词（副）词、或介词短语构成的一种独立成分。
另一种说法：非谓语动词连同自己的逻辑主语做状语。

独立主格结构怎么来的？
Homework was finished, he went out to play.

Homework was finished, he went out to play.
and
（加连词 and 并列句）
第一种改法
homework was finished, he went out to play.
Because
(加连词because 原因状语从句）
第二种改法
第三种改法：去掉was ，破坏其中一个分句的谓语，一个句子 只有一个谓语。
Homework finished, he went out to play.
独立主格结构新定义：
把一个分句或者一个从句破坏了谓语之后，去掉连词剩余更简练的部分， 就称为独立主格结构,这个结构有它自己的主语。

1、独立主格结构不是句子，也不是从句，所以
它内部的动词不能考虑其时态、人称和数的变化;
2、它与其主句之间既不能通过并列连词连接也
不能有从句引导词引导，常用逗号与其主句隔开;
