按动作发生的方式,发生过程的长短,可把动词分为延续性动词和非延续性动词。
延续性动词:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等,可与一段时间连用,如:for 2 years, since he came here, since last year.
非延续性动词:open, close, die, begin, start, finish, come, go, borrow, lend, buy等,不能与一段时间连用。但其否定式可以与一段时间连用。
He has lived here for 2 years. 正确
He hasn’t received her letter for almost a month. 正确
He has left for 2 years. 错误
