词条 | 非延续性动词 |
释义 | 非延续性动词这类动词也可称为终止性动词、瞬间动词、点动词,表示的动作不能延续,即动作发生后立即结束。 这类动词有: arrive/reach 到达 buy 买 close 关 post 邮寄 fall 落下 die 死 leave 离开 go 去 break 打破 lose 丢失 give 给 join 加入 receive 接收 borrow 借 move搬 hear 听到 hear from 收到来信 become 成为 begin/start 开始 finish 结束 marry 娶、嫁 come 来 happen 发生 非延续性动词的用法特征1.非延续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.非延续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状语连用(只限肯定式)。如: (1)他已经死了三年了。 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为非延续性动词,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)将句中非延续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:leave→been 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.非延续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.非延续性动词的否定式与until/till连用,构成"not+终止性动词+until/till ..."的句型,意为"直到……才……"。如: You can't leave here until I arrive.直到我到了,你才能离开这里。 I will not go to bed until I finish drawing the picture tonight.今天晚上直到我画完画,我才上床睡觉。 5.非延续性动词可以用于when引导的时间状语从句中,但不可以用于while引导的时间状语从句中。when表示的时间是"点时间"(从句谓语动词用终止性动词),也可以是"段时间"(从句谓语动词用延续性动词)。而while表示的是一个较长的时间或过程,从句谓语动词用延续性动词。如: When we reached London, it was twelve o'clock. (reach为非延续性动词) Please look after my daughter while/when we are away. (be away为延续性动词短语) 6.非延续性动词完成时不可与how long连用(只限于肯定式)。如: 误:How long have you come here? 正:How long have you been here? 正:When did you come here? |
