been是指什么，为什么要加呢？
还有一个there hasn't been any futher information as to when the boarding time is.
其中been是指什么？as是指什么呢？

it's been delayed for thirty minutes now.这个句子中的it's been delayed= it has been delayed，是现在完成时态的被动语态。意思是：它一直被延迟了……there hasn't been any futher information as to when the boarding time is."as to"是至于或关于的意思。

是英语里的一种时态，现在完成时，当然还可以引申过去完成时，将来完成时

是be的过去分词。此处用于被动语态。
