在英语中什么是延续性动作和非延续性动作?

不一定.有些要跟延续性动词:I have been Beijing for three years.这个句子中时间是for three years.for +一段时间一般和现在完成时的延续性非常动词连用.非延续性动词可用来表示某一动作完成,因此可用于现在完成时。The bus has arrived.火车到了。 又如:He has been dead for three years. 延续性He died three years ago. 非延续性,一般过去时It is three years since he died. 前延续性,后非延续性Three years has passed since he died. 非延续性终止性动词可用于现在完成时否定式中,成为可以延续的状态,因而可与表示一段时间的状语连用。如: He hasn't left here since 1986. I haven't heard from my father for two weeks.
