1、現在完成時講解與練習1.構成 現在完成時是由助動詞 have(has)+動詞的過去分詞構成。助動詞說明該謂語是屬于現在時范圍。它和主語的人稱、數要保持一致。過去分詞是主要的謂語動詞，說明句子的意義。 1表示動作發生在過去某個不確定的時間，但對現在留下了某種影響和結果。常被just、already、yet 等副詞修飾。如： -Have you had lunch yet? -Yes,I have. I've just had it. 你已經吃午飯了嗎？ 我剛剛吃過。現在我不餓了 2表示從過去某一時刻開始一直持續到現在的動作或狀態。這個動作可能剛停止，可能仍然在進行。常帶有for和sinc

2、e等表示一段時間的狀語。 如：He has taught here since 1981 他自1981年就在這兒教書。可能還要繼續教I have't seen her for four years. 我有四年沒見到她了。3結構1 陳述句結構：主語have( has)not+過去分詞其它。have not=havent has not=hasnt.2 一般疑問句結構：Have( Has )主語過去分詞其它？3 特殊疑問句：特殊疑問詞have(has) +主語+ 過去分詞其它？eg. He has already finished his homework. He hasnt finish

3、ed his homework yet. Has he finished his homework yet? -Yes, he has./ No, he hasnt./ No, not yet.3表示說話前發生過一次或屢次的動作，現在成為一種經驗，一般譯為漢語“過，常帶有twice, ever, never, three times等時間狀語。 如： I have been to Beijing twice.我去過北京二次。 1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

4、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一般用于否認句和 疑問句中。如：We have already finished our homework.我們已完成作業了。 They haven't finished their homework yet.他們還沒有完成作業。 b.用ever 和never。多用于否認或疑問句中，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 G

5、reat 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 before, 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.近幾年他去過那里三次了。“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?

6、-No,I haven't.今天你見過他嗎？我 沒有。 How many times have you been there this year? 今年你去過那里多少次？ 2現在完成時可以和帶有since或for等表示“一段時間的狀語連用,表示動作或狀態從某一時刻開始，一直持續到現在。如：I haven't seen him for two years. 但是，像come, arrive, buy等終止性動詞不能與表示“一段時間的狀語連用。要用，必須改為“be在等延續性動詞來表述。現歸納總結一下由非延續性動詞到延續性動詞的轉換： arrivebe here begin(star

7、t)be on die be dead come backbe back leave be away fall ill(sick,asleep)be ill(sick,asleep) get upbe up go out be out finish be over put on wear 或be on open be open join be in或 be a member of close be closed go to schoolbe a student borrow keep buy have catch(a cold) have(a cold) get to know know be

8、gin to studystudy come to workwork等如：He has been a soldier for three years.他參軍三年了。 His father has been dead for two years.他父親去世二年了。 The film has been on for ten minutes.電影已開始十分鐘了。 We have studied English for three years. 我們開始學英語已三年了。 現在完成時和一般過去時都表示在過去完成的動作。但現在完成時強調的是這一動作與現在的關系。如對現在產生的結果或影響等，而一般過去時只表

9、示動作在過去某一時刻發生，不表示和現在的關系。試比擬： I have lost my new book. 我把新書丟了。現在還未找到 I lost my new book yesterday. 我昨天把新書丟了。昨天丟的，現在找到與否沒說明 1have been(to)與have gone( to)的區別：have been(to)表示“去過某地現在已經回來了，可用于各人稱；have gone(to)表示“去某地了說話時某人不在當地，常用于第三人稱，前者可與once ,never,several times等連用，后者那么不能。如：They have been to Beijing twice

10、.他們去過北京兩次。 He has gone to Beijing . 他去北京了。 2如單純表示一段時間，或強調一段時間，雖有since一詞，也不必用完成時。如：It is two years since his father died. =His father has been dead for two years.他父親去世已有三年了。 3終止性動詞現在完成時的否認式，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。 現在完成時練習A 用have(has) b
