1、Unit 3 Language in use延續(xù)性動詞和終止性動詞延續(xù)性動詞和終止性動詞 (1)延續(xù)性動詞和終止性動詞的概念 英語中,動詞按其動作發(fā)生的方式、動作發(fā)生過程的長短,可分為延續(xù)性動詞和終止性動詞。延續(xù)性動詞表示能夠延續(xù)的動作,這種動作可以延續(xù)下去或產(chǎn)生持久影響。如:learn, work,stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。 終止性動詞也稱為非延續(xù)性動詞、瞬間動詞或短暫性動詞,表示不能延續(xù)的動作,這種動作發(fā)生后立即結(jié)束。如:open, close, finis
2、h, begin, come, go, arrive, reach, get to, leave, move, borrow, buy等。 (2)延續(xù)性動詞的用法特征 1)延續(xù)性動詞可以用于現(xiàn)在完成時,其完成時態(tài)可與表示一段時間的狀語連用。表示一段時間的短語有:for two years, during the past three years, since last year, how long等。如: I have learned English since I came here. 自從我來到這兒就學(xué)英語了。 2)延續(xù)性動詞不能與表示短暫時間的狀語連用。如: It rained at e
3、ight yesterday morning. (誤) rain為延續(xù)性動詞,而at eight表示時間點,前后顯然矛盾。如果用延續(xù)性動詞表示一瞬間的動作,可以借助come, begin, get等終止性動詞來表示。上句可改為: It began to rain at eight yesterday morning. 昨天早上八點開始下起了雨。 又如: When did you get to know Jack? Two years ago. Then youve known each other for more than two years. Thats right. (3)終止性動詞的用
4、法特征 1)終止性動詞可用來表示某一動作的完成,因 此可用于現(xiàn)在完成時。如: The train has arrived. 火車到了。 Have you joined the computer group? 你加入電腦小組了嗎? 2)終止性動詞表示的動作極其短暫,不能持續(xù)。因此,不可與表示一段時間的狀語連用(只限肯定式)。如: He has been dead for three years. =He died three years ago. =It is/has been three years since he died. =Three years has passed since he
5、 died. 他死了三年了。 He has been here for five days. =He came here five days ago. =It is/has been five days since he came here. =Five days has passed since he came here. 他來這兒五天了。 、句中的die和come均為終止性動詞,不能與表示一段時間的狀語連用。那么,應(yīng)如何正確表達呢?可以采用下面的四種方法: A. 將句中終止性動詞轉(zhuǎn)換為相應(yīng)的延續(xù)性動詞,如上面兩例中的第一種正確表達方式。下面列舉幾個常見的動詞轉(zhuǎn)換:leavebe away,
6、 borrowkeep, buyhave, begin/startbe on, diebe dead, move tolive in, finishbe over, joinbe in/be a member of, open sth.keep sth. open, fall illbe ill, get upbe up, catch a coldhave a cold。 B. 將句中表示一段時間的狀語改為表示過去確定時間的狀語,如以上兩例中的第二種正確表達方式。 C. 用句型It is+一段時間+since.表達原意,如上面兩例中的第三種正確表達方式。 D. 用句型“一段時間+has pas
7、sed+since.”表達原意,如上面兩例中的第四種正確表達方式。 3)終止性動詞可用于現(xiàn)在完成時的否定式中,變成可以延續(xù)的狀態(tài),此時可與表示一段時間的狀語連用。如: I havent heard from my father for two weeks. 我已有兩周沒收到我父親的來信了。 4)終止性動詞的否定式與until/till連用,構(gòu)成not+終止性動詞+until/till.的句型,意為“直到才”。如: You cant leave here until I arrive. 直到我到了,你才能離開這里。 I will not go to bed until I finish draw
8、ing the picture tonight. 今天晚上直到我畫完畫,我才上床睡覺。 5)終止性動詞可以用于when引導(dǎo)的時間狀語從句中,但不可以用于while引導(dǎo)的時間狀語從句中。when表示的是時間點(從句謂語動詞用終止性動詞),也可以是一段時間(從句謂語動詞用延續(xù)性動詞);而while表示的是一個較長的時間或過程,故從句謂語動詞用延續(xù)性動詞。如: When we reached London, it was twelve oclock. 我們到達倫敦那會兒是十二點。(reach為終止性動詞) Please look after my daughter while/when we are
9、 away. 我們離開時請照顧我女兒。(be away為延續(xù)性動詞短語) 6)終止性動詞的完成時不可與how long連用(只限于肯定式)。如: How long have you been here? 你在這兒有多久了? When did you come here? 你什么時候來這兒的?【話題呈現(xiàn)話題呈現(xiàn)】 本模塊圍繞“My future life”展開話題,要求學(xué)生寫一篇畢業(yè)晚會的演講稿或者寫一篇關(guān)于自己未來生活的文章?!炯丫渌C萃佳句薈萃】 Im very proud that you have chosen me to speak to you today. 我很榮幸今天你們選我給大家
