scarcely had she fallen asleep when a knock at the door awakened her...为什么用had这个过去完成时

正“hardly(scarcely)…when(before)…”(或“no sooner…than…”)结构在英语中用得十分频繁.通常,此结构中主句的谓语动词用过去完成时,从句用一般过去时.正如Practical English Usage 中所说:“Hardly(and scarcely and no sooner)can be used to suggest that one thing happened very soon after another(usu-ally wi th the past perfect tense)”意为Hardly(and scarcely and no sooner)用于暗示一件事在另一件事发生的非常短的时间内发生了.
联系你的句子,意思是说,你才刚刚入睡（可以说几乎都没有睡着）就被敲门声惊醒了.
所以用had过去完成时是一般的惯用用法.但是你也可以从句子中做自己的理解,fallen asleep不管发生了多短的时间,那总之还是在awakened前边,那awakened都用过去式了,那么fallen asleep当然要更退一步用过去完成时了
