16、調過去的事情對現(xiàn)在的影響,強調的是影響。 2)一般過去時常與具體的時間狀語連用,而現(xiàn)在完成時通常與模糊的時間狀語連用,或無時間狀語。 一般過去時的時間狀語:yesterday, last week,ago, in1980, in October, just now等,皆為具體的時間狀語。 現(xiàn)在完成時的時間狀語:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等,皆不確定的時間狀語。 共同的時間狀語:this morning, tonight, this April,
17、now, already, recently, lately 等。 3)現(xiàn)在完成時可表示持續(xù)到現(xiàn)在的動作或狀態(tài),動詞一般是延續(xù)性的,如live, teach, learn, work, study, know.。 一般過去時常用的非持續(xù)性動詞有come, go, leave, start, die, finish, become, get married等。例如: I saw this film yesterday.

(是團員的狀態(tài)可持續(xù)) 句子中如有過去時的時間副詞(如yesterday, last, week, in 1960)時,不能使用現(xiàn)在完成時,要用過去時。 (錯)Tom has written a letter to his parents last night. (

A. was B. have been C. came D. am coming 答案B. This is the first time 后面所加從句應為現(xiàn)在完成時,故選B。 (2) -Have you _ been to
21、 our town before? -No, it's the first time I _ here. A. even, come B. even, have come C. ever, come D. ever, have come 答案D. ever意為曾經(jīng)或無論何時,反意詞為never,此兩詞常用于完成時。 注意:非延續(xù)性動詞的否定形式可以與表示延續(xù)時間的狀語連用。即動作不發(fā)生的狀態(tài)是可以持續(xù)的。 (錯)I have received his letter for a month. (對)I haven't received his letter for almost
22、a month. 11.12 比較since和for Since 用來說明動作起始時間,for用來說明動作延續(xù)時間長度。例如: I have lived here for more than twenty years.我住在這兒二十多年了。 I have lived here since I was born. 我從出生起就住在這兒了。 注意:并非有for 作為時間狀語的句子都用現(xiàn)在完成時。 I worked here for more than twenty years. (我現(xiàn)在已不在這里工作。) I have worked here for many years.(現(xiàn)在我仍在這里工作。)
23、 注意:用句型轉換的方法,很容易排除非延續(xù)動詞在有for/since結構的完成時中的誤用。 1)(對) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now. 2)(錯) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now. 顯然,第二句不對,它

26、eted the work. 他已完成了那項工作。 (表結果) I've known him since then. 我從那時起就認識他了。(表經(jīng)歷) 2) 用于till / until從句的差異 延續(xù)動詞用于肯定句,表示"做直到" 瞬間動詞用于否定句,表示"到,才"。例如: He didn't come back until ten o'clock. 他到10 點才回來。 He slept until ten o'clock. 他一直睡到10點。 典型例題 1. You don't need to describ
27、e her. I _ her several times. A. had met B. have met C. met D. meet 答案B. 首先本題后句強調對現(xiàn)在的影響,我知道她的模樣,你不用描述。再次,several times告知為反復發(fā)生的動作,因此用現(xiàn)在完成時。 2. -I'm sorry to keep you waiting. -Oh, not at all. I _ here only a few minutes. A. have been B. had been C. was D. will be 答案A. 等待的動作由過去開始,持續(xù)到現(xiàn)在,應用現(xiàn)在完成時。 11

A. had written, left B,were
31、 writing, has left C. had written, had left D. were writing, had left 答案D. "把書忘在辦公室"發(fā)生在"去取書"這一過去的動作之前,因此"忘了書"這一動作發(fā)生在過去的過去,用過去完成時。句中when表示的是時間的一點,表示在"同學們正忙于"這一背景下,when所引導的動作發(fā)生。因此前一句應用過去進行時。 注意: had hardly when 還沒等 就。例如: I had hardly opened the door when I he hi
