11.11 用于現在完成時(shí)的句型 1)It is the first / second time.... that…結構中的從句部分,用現在完成時(shí)。例如: It is the first time that I have visited the city. 這是我第一次訪(fǎng)問(wèn)這城市。 This is the first time (that) I‘ve heard him sing. 這是我第一次聽(tīng)他唱歌。 注意:It was the third time that the boy had been late. 2)This is 形容詞最高級 that…結構,that 從句要用現在完成時(shí)。例如: This is the best film that I‘ve (ever) seen. 這是我看過(guò)的最好的電影。 典型例題 (1) ---Do you know our town at all? ---No, this is the first time I ___ here. 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在完成時(shí),故選B。 (2) ---Have you ____ been to 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(wú)論何時(shí),反意詞為never,此兩詞常用于完成時(shí)。 注意:非延續性動(dòng)詞的否定形式可以與表示延續時(shí)間的狀語(yǔ)連用。即動(dòng)作不發(fā)生的狀態(tài)是可以持續的。 (錯)I have received his letter for a month. (對)I haven‘t received his letter for almost a month. 11.12 比較since和for Since 用來(lái)說(shuō)明動(dòng)作起始時(shí)間,for用來(lái)說(shuō)明動(dòng)作延續時(shí)間長(cháng)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(shí)間狀語(yǔ)的句子都用現在完成時(shí)。 I worked here for more than twenty years. (我現在已不在這里工作。) I have worked here for many years.(現在我仍在這里工作。) 注意:用句型轉換的方法,很容易排除非延續動(dòng)詞在有for/since結構的完成時(shí)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,它應改為 Harry got married six years ago. 或 Harry has been married for six years.
11.13 since的四種用法 1) since 過(guò)去一個(gè)時(shí)間點(diǎn)(如具體的年、月、日期、鐘點(diǎn)、1980, last month, half past six)。例如: I have been here since 1989. 1989起,我一直在這兒。 2) since 一段時(shí)間 ago。例如: I have been here since five months ago. 我在這兒,已經(jīng)有五個(gè)月了。 3) since 從句。例如: Great changes have taken place since you left. 你走后,變化可大了。 Great changes have taken place since we were here. 我們走后,變化可大了。 4) It is 一段時(shí)間 since從句。例如: It is two years since I became a postgraduate student. 我考上研究生有兩年了。 11.14 延續動(dòng)詞與瞬間動(dòng)詞 1) 用于完成時(shí)的區別 延續動(dòng)詞表示經(jīng)驗、經(jīng)歷; 瞬間動(dòng)詞表示行為的結果,不能與表示段的時(shí)間狀語(yǔ)連用。例如: He has completed the work. 他已完成了那項工作。 (表結果) I‘ve known him since then. 我從那時(shí)起就認識他了。(表經(jīng)歷) 2) 用于till / until從句的差異 延續動(dòng)詞用于肯定句,表示”做……直到……” 瞬間動(dòng)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(diǎn)才回來(lái)。 He slept until ten o‘clock. 他一直睡到10點(diǎn)。 典型例題 1. You don‘t need to describe 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(dòng)作,因此用現在完成時(shí)。 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(dòng)作由過(guò)去開(kāi)始,持續到現在,應用現在完成時(shí)。 #p#分頁(yè)標題#e#
