延续性动词与非延续性动词 动词按其动作发生的方式、发生过程的长短可分为延续性动词与非延续性动词。 一.延续性动词表示能够延续的动作,如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。延续性动词可以与表示时间段的状语连用。 表示时间段的短语有: 1.for+一段时间, eg: for 2 years; for a long time 等 2.since 从句,since he came here; 3.since+时间点+ago,eg：since last year, since 5 days ago; 4. how long; 二.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等。 如果要与for+ 时间段，since+年份，since+时间段+ago，how long 连用时，瞬间性动词要变延续性动词。 三.延续性动词与非延续性动词之间的转换： 非延续性动词 延续性动词 leave be away(from) borrow keep buy have begin/start be on die be dead finish be over join be in+组织机构;be a member of+组织机构 open sth. keep sth. open come here be here go there be there become be come back be back come to/get to/ arrive(in/at)/reach/ move to be (in)/stay(in/at) go (get) out be out put on wear fall ill be ill get up be up catch a cold have a cold fall asleep be asleep get to know know wake up be up close be closed 例：（1）他死了三年了。 误：He has died for three years. 正：He has been dead for three years. 正：He died three years ago. 正：It is three years since he died. 正：Three years has passed since he died. (2) 他来这儿五天了。 误：He has come here for five days. 正：He has been here for five days. 正：He came here five days ago. 正：It is five days since he came here. 正：Five days has passed since he came here. (1)、(2)句中的 die、come 为终止性动词，不能与表示"段时间"的状语连用。那么，应如何正确表达呢？可以采用下面的四种方法： (1) 将句中终止性动词转换为相应的延 续性动词,...
