1、精選優質文檔-傾情為你奉上 現在完成進行時1 定義:現在完成進行時表示動作從過去某一時間開始，一直延續到現在，可能還要繼續下去。2 現在完成進行時的構成:現在完成進行時是由“have/has+been+動詞的現在分詞”構成3 現在完成進行時的基本句型肯定式 I/We have been working.疑問式 Have you been working？ 簡略回答 Yes，I/we have. No，I/we haven't.肯定式 He/She/It has been working.疑問式 Has he/she/it been working？ 簡略回答 Yes，he/she/it

2、 has. No，he/she/it hasn't.4.現在完成時的用法:其用法主要有三種 I.“已完成”用法 :表示一個過去發生并結束的動作對現在造成的影響或結果。這一類情況可以細致分為下述兩種情況。 1）表示開始于過去的動作剛剛結束。常和just，now，already，yet，notyet等不確定的時間狀語連用。 Li Ming has just turned off the light. 李明剛剛把燈關上。（說明現在燈關上了） I've finished my homework now. 現在我已經做

3、完作業了。（說明可以交作業或做別的了） 2）表示過去動作的結果，現在仍殘留著。一般不用時間狀語。 I have lost my pen. 我把筆丟了。 （說明過去某時丟的，現在我還沒找到這支筆）She has become a teacher. 她已經當了老師。（說明她現在仍是老師）  II.“未完成”用法。表示動作或狀態從過去某時開始，持續到現在，可能繼續下去，也可能剛剛結束。常和表示一段時間的狀語連用。如today，this week（month），lately，recently，these days，in the pa

6、ng here for ten years.We've lived here for ten years.我們在這兒已經住了十年了。2）在不用時間狀語的情況下，現在完成進行時表示動作仍在進行。而現在完成時則表示動作在過去已結束。如：The students have been preparing for the exam.（還在進行）學生們一直在準備考試。The students have prepared for the exam.（已經結束）學生們為考試作了準備。3）有些表示狀態，感情，感覺的動詞如：have，exist，like，hate，hear，know，sound等動詞不能

7、用于現在完成進行時，但可用于現在完成時。如：They've known each other since 1970.自從1970年起他們就相互認識了。三.現在完成時的時間狀語 I現在完成時屬于現在時范圍，故不能和過去的時間狀語連用。如：yesterday,last Sunday,in1990,three years ago等。但是，在強調動作產生的后果和影響時，可以和一些表示不確定的時間狀語連用。a. 用副詞already和yet。already一般用于肯定句中，yet一般用于否定句和疑問句中。如：We have already finished our homework.我

8、們已完成作業了。 They haven't finished their homework yet.他們還沒有完成作業。b. 用ever和never.多用于否定或疑問句中，表示“曾經”或“從未“等。 如： -Have you ever been to the Great Wall?你曾經去過長城嗎?-I have never been to the Great Wall.我從未去過長城。 c. 用表示到說話為止的過去時間狀語，如just, before, up to now, the past few years等。例如：I have seen her b

9、efore,but I can not remember where. 我以前見過她，但記不起在哪里見過。 He has been there three times the last few days. 近幾天他去過那里三次了。 d. 用包括“現在”在內的時間狀語，如now,today,this morning(month,year,term)等。例如：-Have you met him today?-No,I haven't. 今天你見過他嗎？我沒有。 How many times have you been there

10、this year? 今年你去過那里多少次？ II短暫性動詞不能和表一段時間的時間狀語連用。如：come, go, arrive, reach, hear, close, leave, begin, start, lose, buy, fall, join, die, get up等。但如果要保留表一段時間的時間狀語，必須將動詞改為延續性動詞。現歸納總結一下由非延續性動詞到延續性動詞的轉換如：  fall asleep (ill) be asleep (ill)        

11、0; get to know know  begin,(start) be on                     open be open   buy have

18、They have been to Beijing twice.他們去過北京兩次。 He has gone to Beijing . 他去北京了。 II.不可延續性動詞現在完成時的否定式，已變成一種可以延續的狀態，因此可以和表示一段時間的狀語連用。如： I haven't left here since 1997.自從1997年以來，我一直沒有離開過這兒。 （錯）I have received his letter for a month. （對）I haven't received his letter for almost
