2、可能刚停止，可能仍继续进行下去，常与延续动词连用。并常接带有表示动作起迄时间的状语，如since last week, since 1997等或由since引导的时间状语从句，也可以带有表示时间长短的状语，如for an hour, for a few days, these days等。例如：He has been living there since 1970. 他从1970年以来就住在这里。（试与He has lived there since 1970. 比较。）I have been writing letters.我一直在写信。（试与I have written two lette
