20、構(gòu)成1)現(xiàn)在完成時的肯定句句型 主語（第一、二人稱單 /復數(shù)） +have+過去分詞主語（第三人稱復數(shù)） +have +過去分詞主語（第三人稱單數(shù)） +has+過去分詞have (has) 為助動詞e.g. he has already had his lunch. e.g. i have just finished my homework. 2)現(xiàn)在完成時的否定句句型主語+have/has not(havent/hasnt)+ 過去分詞e.g. i have not seen the movie yet. e.g. she hasn t eaten it.3)現(xiàn)在完成時的一般疑問句have/

21、has+主語+過去分詞 +？e.g. have you finished the work? e.g. has she arrived here? e.g. have they eaten supper? 三、過去分詞的構(gòu)成a .規(guī)則動詞的過去分詞（參照動詞的過去式變化規(guī)則）b .不規(guī)則動詞的過去分詞（書p122-123）四、用法1：表示過去開始的動作或狀態(tài)已經(jīng)結(jié)束，但是對現(xiàn)在有影響。這種用法常與 already, just, yet, ever, never, times (次數(shù) ) 等連用 .e.g. look! the blackboard is so clean now. he has

22、 already cleaned the blackboard. 這句話所表示強調(diào)的結(jié)果是黑板現(xiàn)在是干凈的。(他已經(jīng)擦過黑板了。 ) 現(xiàn)在完成時的時間副詞和時間短語: 1)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。e.g. we have already finished our homework. 8 2)副詞 ever 和 never。多用于否定或疑問句中，表示“ 曾經(jīng)” 或“ 從未“ 等。e.g. have you ever been to the great wall? 你曾經(jīng)去過長城嗎 ? 3)用 just 表示到說話時為

23、止的時間狀語, e.g. i have just seen her, but i dont know where she is now .注意：當在肯定陳述句中含有already 或 just 時，在轉(zhuǎn)換成否定句或疑問句時，要把句中的 already 或 just 去掉，在句末加上yet. e.g. i have done my homework already. i havent done my homework yet. 用法 2.:表示過去的動作一直持續(xù)到現(xiàn)在甚至未來時間狀語: since, for 過去的時間點 since 1990, since last year 現(xiàn)在完成時 + s

24、ince + 時間段 +agosince three years ago 句子（一般過去時）since i went to school e.g. he has gone to beijing since 3 years ago. 現(xiàn)在完成時 + for +一段時間for three years e.g. i have studied english for ten years. 【疑難題導析 】1)he has never _ a pen before. a. lose b. to lose c. lost d. losing 解析答案為 c。 本題主要考查現(xiàn)在完成時態(tài)對謂語動詞的要求。現(xiàn)在

25、完成時態(tài)謂語動詞的結(jié)構(gòu)是have (has)+ 過去分詞。 本題空白處需要過去分詞， 這樣 a、b、d 都不對。2) 誤：the twins have not got home already. 正：the twins have not got home yet. 解析：本題主要考查yet 與 already的用法區(qū)別，兩個詞都是副詞，常與完成時態(tài)連用。 yet 用于否定句和疑問句，提通常置于句尾；already 常用于肯定句，當用于疑問句時， 表示驚訝或希望得到肯定的答復，不用于否定句中， 它可以在主要動詞之前，也可置于句末。3)jim has been at the factory_ tw

26、o years ago. a. for b. since c. before d. after 解析：答案為 b。 本題主要考查時間狀語與謂語的關(guān)系。for 后跟時間段表示一9 段時間 ,since 后跟時間段 +ago，表示一段時間 ,before 表示在什么時間之前,after則表示在什么時間之后。本句是完成時態(tài)，指自兩年前以來如何，且兩年前是個時間的（起）點，因此，此處應(yīng)用since. 4)誤:i saw the film twice already. 正:i ve seen the film twice already. 解析； 本題主要是一般過去時態(tài)與現(xiàn)在完成時態(tài)的概念錯誤。這電影我

27、已看過兩遍，說明我現(xiàn)在對電影內(nèi)容很了解，故要用現(xiàn)在完成時態(tài)。5)_you _ your watch? - no,_. a. did, find out, i didn t b. have, found, not yet c. have, looked for, i haven t d. did, find, not yet 答案選“b” 。全句應(yīng)用現(xiàn)在完成時， 強調(diào)到現(xiàn)在為止的情況 “是否找到了手表”，答語； not yet 相當于說i havent found it yet. 6)i have never seen the film _. a. ago b. just now c. befo

28、re d. later 答案選“c” 。 動詞時態(tài)為現(xiàn)在完成時， 與之搭配的詞必須是ever, never, already, yet, before, recently 等詞。而ago, just now 等只能用于一般過去時句子中，用later 意思不通【專項練習 】一、單項選擇題1. how long have you _ here? a. come b. got c. arrived d. been 2.i have finished my homework _. have you finished your homework _? a. yet, yet b. yet, alread
