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

請(qǐng)問(wèn)老師，這是獨(dú)立主格吧，可以用had been canceled 嘛？

獨(dú)立主格結(jié)構(gòu)為分詞作狀語(yǔ)。假如用had been cancelled, 就成了謂語(yǔ)動(dòng)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(dú)立主格結(jié)構(gòu)作緣由狀語(yǔ)

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