        現在完成時是由助動詞 have(has)+動詞的過去分詞done構成。助動詞have說明該謂語是屬于現在時范圍。它與主語的人稱、數要保持一致。過去分詞done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與結果。常與just、already、yet 等副詞連用。如:
        ---Have you had dinner yet?你(已經)吃晚飯了嗎?
        ---Yes,I have. I''ve just had it. 我剛剛吃過。(強調現在我不餓了)
        如:He has livedin ShangHai since 2001.
        (3)表示說話前發生過一次或多次的動作,現在成為一種經驗,一般譯為漢語“過”,常帶有ever,never,twice,three times等時間狀語。
        如: I have been to Shanghai three times.我去過上海三次。
        1)陳述句結構:主語+have/has(not)+過去分詞+其它。have not=haven''t  has not=hasn''t.
        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。
        例如:She has already seen the film.
        She hasn’t seen the film yet.
        Has she seen the film yet?
        Yes,she has./ No,she hasn''t.
        現在完成時屬于現在時范圍,故不能與過去的時間狀語連用。但是,在強調動作產生的后果與影響時,可以與一些表示不確定的時間狀語連用。有  already,yet,since,for,ever,never,just,before,up to now等。
        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。
        I have never been to the Great Wall.我從未去過長城。
        We have studied English for three years. 我們(開始)學英語已三年了。
        (1)have 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,后者則不能。如:They have been to Beijing twice.他們去過上海兩次。
        He has gone to Beijing . 他去上海了。
        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。
        如:I haven''t left here since 1997.自從1997年以來,我一直沒有離開過這兒?! 【氁痪殻?br /> 一、用since與for填空。
