1、延续性动词和终止性动词一、延续性动词和终止性动词的概念 英语中,动词按其动作发生的方式、动作发生过程的长短,可分为延续性动词和终止性动词。延续性动词表示能够延续的动作,这种动作可以延续下去或产生持久影响。如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。 终止性动词也称非延续性动词、瞬间动词或短暂性动词,表示不能延续的动作,这种动作发生后立即结束。如open,
2、 close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。 二、延续性动词的用法特征 1.延续性动词可以用于现在完成时,其完成时态可与表示"段时间"的状语连用。表示"段时间"的短语有:for two years, during the past three years, since last year, how long等。如:I have learned English since I cam
3、e here.自从我来到这儿就学英语了。 2.延续性动词不能与表示短暂时间的"点时间"状语连用。如:It raind at eight yesterday morning.(误) rain为延续性动词,而at eight表示"点时间",前后显然矛盾。如果用延续性动词表示一瞬间的动作,可以借助come, begin, get等终止性动词来表示。上句可改为:It began to rain at eight yesterday morning.(正)又如: -When did you get to k
4、now Jack? -Two years ago. -Then you've known each other for more than two years. -That's right. 三、终止性动词的用法特征 1.终止性动词可用来表示某一动作完成,因此可用于现在完成时。如: The train has arrived.火车到了。 Have you joined the computer group?你加入电脑小组了吗? 2.终止性动词表示的动作极其短暂,不能持续。因此,不可与表示一段时间的
5、状语连用(只限肯定式)。如: (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 b
6、een 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,如上面两例中的第一种正确表达方式。下面列举几例:lea
7、ve→be away, borrow→keep, buy→have, begin/start→be on, die→be dead, move to→live in, finish→be over, join→be in/be a member of, open sth.→keep sth. open, fall ill→be ill, get up→be up, catch a cold→have a cold。 (2)将句中表示"段时间"的状语改为表示过去确定时间的状语,如下面两例中的第二种正
8、确表达方式。 (3)用句型"It is+段时间+since..."表达原意,如上面两例中的第三种正确表达方式。 (4)用句型"时间+has passed+since..."表达原意,如上面两例中的第四种正确表达方式。 3.终止性动词可用于现在完成时否定式中,成为可以延续的状态,因而可与表示一段时间的状语连用。如: He hasn't left here since 1986. I haven't heard from my father for two weeks. 4.终止性动词
