(1)This is one of the rarest questions that have ever been raised at such a meeting.
(2)There was a knock at the door. It was the second time someone had interrupted me that evening。
比较一般过去时与现在完成时

I have lived here since I was born.我从出生起就住在这儿了。
注意:并非有for作为时间状语的句子都用现在完成时。
I worked here for more than twenty years.(我现在已不在这里工作。)
I have worked here for many years.(现在我仍在这里工作。)
