All the flights having been canceled because of the snowstorm, we had to take the train instead.

請問老師，這是獨立主格吧，可以用had been canceled 嘛？

獨立主格結(jié)構(gòu)為分詞作狀語。假如用had been cancelled, 就成了謂語動詞了，要么用并列句，要么用主從復(fù)合句：

All the flights having been canceled because of the snowstorm, we had to take the train instead.獨立主格結(jié)構(gòu)作緣由狀語

Because all the flights had been canceled because of the snowstorm, we had to take the train instead.緣由狀語從句

All the flights had been canceled because of the snowstorm, so we had to take the train instead. so連接并列句
