独立主格结构是一种特殊的语法结构，它由一个名词（或代词）和一个分词、形容词、副词、不定式或介词短语组成，用来表示时间、原因、条件、伴随状况等。独立主格结构在句中作状语，与主句之间通常用逗号隔开。以下是一些独立主格结构的例句：

时间状语

The test finished, we began our holiday.

After class was over, the students soon left the classroom.

With the exam coming up, Jane spent all her time studying.

原因状语

Weather permitting, we are going to visit you tomorrow.

The president assassinated, the whole country was in deep sorrow.

Seeing the opportunity, she decided to take the job.

条件状语

If weather permits, we will have a picnic tomorrow.

Unless the rain stops, we won't be able to go hiking. [未提供具体例句]

伴随状况

He came into the room, his ears red with cold.

She came out of the library, a large book under her arm.

They sat there, talking and laughing, enjoying the warm sun. [未提供具体例句]

原因状语（与主句主语不同）

Her being sick, she couldn't attend the meeting.

His being late, the meeting had to be rescheduled. [未提供具体例句]

补充说明

The weather being nice, we decided to have a picnic.

They were tired, so they decided to go to bed early. [未提供具体例句]

在使用独立主格结构时，需要注意以下几点：

独立主格结构的逻辑主语与句子的主语不同，它独立存在。

名词或代词与后面的分词、形容词、副词、不定式、介词等是主谓关系或动宾关系。

独立主格结构一般有逗号与主句分开。

有时可以在独立主格结构前加上介词，如“with”、“without”等。

希望这些例句能帮助你更好地理解和掌握独立主格结构的用法。
