四、-ed分词在复合结构中

Don't get your schedule changed; stay with us in this class.

Peter had his gas and electricity turned on when he moved into his new apartment last month.

He kept his mouth shut and stayed where he was.(他闭口不言，呆在原地不动。)

They are talking about the experiment made in the new lab.

五、独立结构

如果-ed分词短语与-ing短语带有与句子主语不同的主语，即本短语自己本身带有主语，这就构成了独立结构(也叫独立主格结构或垂悬结构)，这种结构也可作状语表示时间，原因等。有时在独立结构前还可加介词with 或 without。

Her eyes filled with tears, she did not notice his coming.

18) This ________, we went out to play.

[A] was done

[B] did

[C] was dong

[D] done

解析：D为正确答案。A是不对的，如果we前加上and，才能选A。

19) _______ all his followers dead, the commander was taken by his enemy.

[A] For

[B] As

[C] Because of

[D] With

解析：D为正确答案。
