7. 在绝大数情况下,句子的逻辑主语是句子的主语,但有时前可有一个名词或代词表示逻辑上的主语,这种带逻辑主语的称为独立主格结构。
独立主格,首先它是一个“格”,而不是一个“句子”,在英语中任何一个句子都要有主谓结构,而在这个结构中,没有真正的主语和谓语动词,但又在逻辑上构成主谓或主表关系。

The meeting being over, we all left the
room and drove home.
会议结束后,我们都离开房间开车走了。
It being a holiday, all the shops were shut.
由于今天是假日,所有商店都关门了。
独立主格结构是由“主格人称代词或通格+V-ing”构成.
Time permitting, we'll go outing. 如果时间允许,我们就去效游.
独立格结构在句中作状语,表示伴随时间,条件,原因,让步,相当于状语从句或并列句.
He hearing the news, tears of joy came into his eyes.
As soon as he heard the news, tears of joy came into his eyes.
8. 有少数并不表示句子主语的动作,而是表示说话人的态度。
Generally speaking, the novel is not very inspiring.
总的来说,这部小说并不感人。

Judging from what you say, he ought to
succeed.
从你说的情况看,他应能成功。
