独立主格是一种特殊的语法结构，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、不定式或介词短语作为谓语构成。这种结构在句子中作状语，表示时间、原因、条件、伴随等。以下是一些独立主格的例句：
用作时间状语
The work done, we went home.
The test finished, we began our holiday.
After the meeting gone over, everyone tired to go home earlier.
用作条件状语
Weather permitting, they will go on an outing to the beach tomorrow.
If weather permits, we are going to visit you tomorrow.
The president assassinated, the whole country was in deep sorrow.
表示原因
Him being absent caused the delay.
Me being sick, I couldn't go to the party.
表示伴随
The little girl came in, her face red with anger.
The cat lay under the table, its eyes closed in sleep.
He came into the room, his ears red with cold.
She came in with a book in her hand.
表示状态
The man lay there, his hands trembling.
The weather being nice, we decided to have a picnic.
表示目的
They are studying in college, in order to find good jobs in the future.
这些例句展示了独立主格在不同语境下的应用，能够有效地表达时间、原因、条件、伴随等概念。在使用独立主格时，需要注意其逻辑主语与句子的主语不同，并且通常用逗号与主句分开。
