________________,the film began.
A Having been seated
B All of us having taken the seats
C Having seated
D After we have sat down

英语 英语 (26 11:12:58)________________,the film began.A Having been seatedB All of us having taken the seatsC Having seatedD After we have sat down
Answer：D
A：Having been seated 的主语不是the film
B：主语不能直接加进行时,这不是非谓语
C：跟A一样
D：对

B
选D的话应该是After we had sat down，原本是个状语从句，但时态不符合，根据分词主语与句子主语一致所以A、C也不能选

选B这里是一个独立主格结构，前面的句子和后面的分局不是一个主语，前面是，所以只能用独立主格结构。电影开始的时候，我们都坐好了。

我觉得是D
首先AC缺少主语，be seated =sit
having done 不可以作状语，只可以作主语
不太确定啊

这是独立主格结构，简言之主语不相等，状语用非谓语动词。句子主语是the film,排除ACD,选B
