注意:动词ing 形式作状语时,其逻辑主语必须与句子的主语一致,且必须与句子的主语是逻辑上的主谓关系,动词ing 形式表示的动作是次要动作。(一个主语多个动作。)
四、独立成分
(1) 有些分词短语可以作独立成分,用来解释这个句子,不受句子主语的限制。
常见分词短语有:
generally speaking(一般说来), supposing(假设), judging from / by (从...判断)...
Generally speaking, girls are more careful than boys.
Supposing you lose, what will you do?
Judging from his accent, he must be from the south.
(2) 分词短语作状语时,它的逻辑主语一般需与句子的主语一致。但有时它也可以有自己独立的逻辑主语,这种结构称为独立主格结构。独立主格结构通常用来表示伴随的动作或情况,有时还可以表示时间、原因或条件。如:
Night coming on(=When night came on), we started for home.
So many people being absent (=___________), they decided to put off the meeting.
这么多人没来,他们决定会议延期举行。
如果天气允许的话,我们就步行到那里。______________________________
