1.They have been married for three years.是完成时的被动语态吗?
如果不是,要怎么分辨?还有这句 2.I have been asleep for 2 hours.3.He has been away from Beijing for three years.非延续性动词常用有哪些?非延续性动词转化为延续性要怎么转化?4.They were married last year.这句是被动语态吗?

1,2,3句都是现在完成时而非完成时被动语态.判断句子是主动还是被动可以根据句意或者动词形式,如果是被动been后面一定跟的是过去分词.
"非延续性动词也称终止性动词、瞬间动词　　表示不能延续的动作,这种动作发生后立即结束.如:open,die,close,begin,finish,come,go,move,borrow,lend,buy,arrive等.
非延续性动词在肯定句中与表示时间点的状语连用,如：two years ago; at 5 o'clock;
例:He died 5 years ago.
否定的终止性动词可以与表示时间段的时间状语连用.例:I haven't left here for 3 years.I haven't heard from him for 3 weeks.
