《延续性和非延续性动词.docVIP

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 将非延续性动词转化成延续性动词 Leave-be away Borrow-keep Buy- have Begin,start-be on Die- be dead Finish/end/stop-be over Join-be in+组织机构 Open/close-keep sth open/closed Fall ill- be ill Get up- be up Catch/get a cold-have a cold Fall asleep-be asleep Become-be Come back-be back Get to/arrive at/reach-be in Put on-wear Lose one’s job/work-be out of work/a job 1.
