unit 9 現(xiàn)在完成時

1、 現(xiàn)在完成時 現(xiàn)在完成時（一）含義和標(biāo)志性詞語現(xiàn)在完成時的意義： 現(xiàn)在完成時表示過去發(fā)生或完成的某一動作對現(xiàn)在造成的影響或結(jié)果。（過去時強(qiáng)調(diào)過去某個特定的時間發(fā)生的動作或存在的狀態(tài)；現(xiàn)在完成時表示過去不確定的時間里發(fā)生的動作對現(xiàn)在造成的影響和結(jié)果，這個動作也許到現(xiàn)在結(jié)束，也許還要繼續(xù)下去。）如： Have you read that story？你讀過那個故事嗎？（“讀”這一動作發(fā)生在過去，對現(xiàn)在造成的影響是：是否知道故事的內(nèi)容） 現(xiàn)在完成時的標(biāo)志性詞：時間狀語：before，lately，recently, till now，so far， in the past few years/mon

2、ths/weeks/days，over the past few years，during the last three months，for the last few centuries For + 時間段 、since + 時間點（短語/從句）常與現(xiàn)在完成時連用的幾個重要副詞：already，just，yet，ever，never等。already 多用于肯定句中中或末尾， just 用在肯定句中，ever 多用于疑問句中yet 用在否定句和一般疑問句末。 Never 用在肯定句中表否定。如：I hav e already finished my homework我已經(jīng)做完家庭作業(yè)了。 H

3、e has just had his meal他剛吃過飯。 Have you ever sung this English song？你曾唱過這首英文歌嗎？ They haven't started yet他們還沒有動身。 We have never heard of it我們從來沒有聽說過這件事。 動詞形式：過去分詞的變化規(guī)則形式和發(fā)音規(guī)則與過去式是一樣的，除了一些不規(guī)則變化。 現(xiàn)在完成時（二）結(jié)構(gòu)1現(xiàn)在完成時的基本句式是“have（has）過去分詞”。如：I have seen that film我已經(jīng)看過那部影片了。 We have just finished our homew

4、ork我們剛剛做完家庭作業(yè)。 She has gone home她回家去了。 注意：1）該句式中的have或has是助動詞，has用于第三人稱單數(shù)，其它人稱一律用have。2）該句式中have（has）和過去分詞之間可用just插入。3）把該句式譯成漢語時，往往用“已經(jīng)”、“剛剛”、“過”或“了”等。 2現(xiàn)在完成時的一般疑問句式是把助動詞have或has提到主語之前。如： Have you read this story book yet？你讀過這本故事書嗎？ Has he eaten that apple yet？他吃那個蘋果了嗎？ 注意：1）現(xiàn)在完成時的一般疑問句往往在句末加yet。2）把

5、現(xiàn)在完成時的一般疑問句譯成漢語時，往往譯成“過嗎？”、“還有嗎？”。3）其肯定回答用：Yes，have（has）否定回答用：No，haven't（hasn't）有時用：No，not yet或No，never 3現(xiàn)在完成時的否定句式是“have（has）not + 過去分詞”。如： We haven't studied Unit 2 yet我們還沒學(xué)習(xí)第二單元。 The train hasn't stopped yet火車還沒有停下來。 注意區(qū)別：Has/have been to Has/have been in Has/have gone toHave been

6、 in 表示“去了某地并正在某地”have been(to)表示“去過某地（現(xiàn)在已經(jīng)回來了）”，可用于各人稱；have gone(to)表示“去某地了（說話時某人不在當(dāng)?shù)兀?，常用于第三人稱，前者可與once ,never, several times等連用，后者則不能。如：They have been to Beijing twice.他們?nèi)ミ^北京兩次。He has gone to Beijing .  他去北京了。He has been in Beijing for two weeks. (has been in 后接for/since時間狀語) 現(xiàn)在完成時（三）與過去時的區(qū)別&

7、amp;短暫性動詞的轉(zhuǎn)換1現(xiàn)在完成時態(tài)既涉及過去，又聯(lián)系現(xiàn)在，它可表示動作或狀態(tài)過去已經(jīng)開始一直延續(xù)到現(xiàn)在，和由for或since引導(dǎo)的時間狀語連用。例如： We have lived here for five years我們在這里住了五年了。 I have known him since he was a boy我從他還是個孩子的時候就認(rèn)識他了。 注意：現(xiàn)在完成時與一般過去時的區(qū)別：現(xiàn)在完成時強(qiáng)調(diào)過去發(fā)生的事對現(xiàn)在造成的影響；一般過去時指過去發(fā)生的事實。請看下面對話中一般過去時和現(xiàn)在完成時的不同。 A：Have you seen the film？ B：Yes，I have A：When

8、did you see it？ B：I saw it a year ago 2延續(xù)性動詞與非延續(xù)性動詞在現(xiàn)在完成時中的使用。 （1）延續(xù)性動詞：be，have，know，live， work，study，learn，teach，speak，talk，draw， wait，wear，walk，sleep等，這些動詞可以和表示一段時間的狀語連用。例如： Uncle Wang has worked in this factory for ten years王伯伯在這家工廠工作十年了。 （2）非延續(xù)性動詞：come，go，arrive， reach，see，hear，close，leave，begin

9、，start，lose， buy，fall，join，die等，這些動詞可用于完成時態(tài)，說明某個動作的結(jié)果還存在，但不能和表示一段時間的狀語連用。例如： 【正】The play has begun戲開演了。（戲正在演著） 【誤】The play has begun for half an hour戲開演半小時了。 【正】The play has on for half an hour. 戲上演半個小時了。3非延續(xù)性動詞的轉(zhuǎn)換常見的非延續(xù)性動詞與延續(xù)性動詞轉(zhuǎn)換如下：(一般過去時變現(xiàn)在完成時動詞及動詞詞組的變化方法)comebe， come tobe in at， arrivebe here, g
