3、示到現(xiàn)在為止已經(jīng)完成或仍在持續(xù)的動(dòng)作、狀態(tài)；強(qiáng)調(diào)對(duì)現(xiàn)在的影響或聯(lián)系2、基本結(jié)構(gòu)助動(dòng)詞have/has+過去分詞(done) 3、句型 否定句： 主語+have/has+not+過去分詞+其他. 一般疑問句： Have/Has+主語+過去分詞+其他. 簡(jiǎn)略答語： Yes, 主語 + have/has.(肯定) No, 主語 + havent/hasnt.(否定) 4、用法：1）動(dòng)作發(fā)生在過去，強(qiáng)調(diào)對(duì)現(xiàn)在的影響。與一般過去時(shí)的區(qū)別：強(qiáng)調(diào)過去一般過去式強(qiáng)調(diào)對(duì)現(xiàn)在的影響-現(xiàn)在完成時(shí)。 試比較： I have lost my new book. 我把新書丟了。（現(xiàn)在還未 找到） I lost my ne

4、w book yesterday. 我昨天把新書丟了。（昨天丟的，現(xiàn)在找到與否沒說明）My mother went to Shanghai. Where is your mother? -She has gone to Shanghai. . I didnt have breakfast. I havent have breakfast yet. 2）動(dòng)作發(fā)生在過去某個(gè)不確定的時(shí)間，但對(duì)現(xiàn)在有某種影響和結(jié)果。常被just、already、 yet 等副詞修飾。如： -Have you had lunch yet? -Yes, I have. Ive just had it. 你（已經(jīng)）吃午飯了

5、嗎？ 我剛剛吃過。（現(xiàn)在我不餓了）3）現(xiàn)在完成時(shí)表示未完成。動(dòng)作從過去延續(xù)到現(xiàn)在，還可能以后繼續(xù)。通常和帶有for和since等表示一段時(shí)間的狀語。 He has been in the army for ten years.I have studied English since 1980. 4）表示說話前發(fā)生過一次或多次的動(dòng)作，現(xiàn)在成為一種經(jīng)驗(yàn)，一般譯為漢語“過”，表示次數(shù)：一次once; 二次: twice, 三次：three times, ever, never等時(shí)間狀語。 如： I have been to Beijing twice.我去過北京二次、I have been to S

6、hanghai twice.She has watched this film three times.I have never seen more beautiful girl than she. 5、現(xiàn)在完成時(shí)常與一些詞、詞組連用 :1）、ever（曾）、never（未曾）、already（已經(jīng)） 、 yet（仍、還）、just （剛剛）、before（以前)2）、for +一段時(shí)間 : for two days 有兩天了3、. in the past/last一段時(shí)間 : in the past ten years 在剛過去的十年里4）、. since + 過去某一個(gè)時(shí)間: since

11、/get to-be go out-be out leave -be away begin-be on finish-be over open-be open close -be closed die-be dead(死) 1、have代替buy ： My brother has had(不能用has bought) this bike for almost four years. 2、用keep或have代替borrow： I have kept(不能用have borrowed) the book for quite a few days. 3、用be替代become： How long

12、has your sister been a teacher? 4、用have a cold代替catch a cold： Tom has had a cold since the day before yesterday. 5、用wear代替put on b)用“be+形容詞”代終止性動(dòng)詞 1、be married代marry 2、be ill代fall (get) ill 3、be dead代die 4、be asleep代fall (get) asleep 5、be awake代wake/wake up 6、be gone代lose,die,sell,leave 7、be open代op

18、呆的地方） eg：My father has been in Shanghai for two months/since two months ago. (三) 比較過去時(shí)與現(xiàn)在完成時(shí) 1）過去時(shí)表示過去某時(shí)發(fā)生的動(dòng)作或單純敘述過去的事情，強(qiáng)調(diào)動(dòng)作；現(xiàn)在完成時(shí)為過去發(fā)生的，強(qiáng)調(diào)過去的事情對(duì)現(xiàn)在的影響，強(qiáng)調(diào)的是影響。 2）過去時(shí)常與具體的時(shí)間狀語連用，而現(xiàn)在完成時(shí)通常與模糊的時(shí)間狀語連用，或無時(shí)間狀語。一般過去時(shí)的時(shí)間狀語:yesterday, last week，ago, in1980, in October, just now, 具體的時(shí)間狀語共同的時(shí)間狀語:this morning, to

19、night,this April, now, once，before, already, recently，lately現(xiàn)在完成時(shí)的時(shí)間狀語for, since, so far, ever, never, just, yet,till / until, up to now, in past years, always,不確定的時(shí)間狀語 3）現(xiàn)在完成時(shí)可表示持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)，動(dòng)詞一般是延續(xù)性的，如live, teach, learn, work, study, know. 過去時(shí)常用的非持續(xù)性動(dòng)詞有come, go, leave, start, die, finish, become, g

20、et married等。舉例： I saw this film yesterday.（強(qiáng)調(diào)看的動(dòng)作發(fā)生過了。） I have seen this film. （強(qiáng)調(diào)對(duì)現(xiàn)在的影響，電影的內(nèi)容已經(jīng)知道了。） Why did you get up so early?（強(qiáng)調(diào)起床的動(dòng)作已發(fā)生過了。） Who hasnt handed in his paper?（強(qiáng)調(diào)有卷子，可能為不公平競(jìng)爭(zhēng)。） She has returned from Paris. 她已從巴黎回來了。 She returned yesterday. 她是昨天回來了。 He has been in the League for thre

21、e years.(在團(tuán)內(nèi)的狀態(tài)可延續(xù)) He has been a League member for three years.(是團(tuán)員的狀態(tài)可持續(xù)) He joined the League three years ago. ( 三年前入團(tuán)，joined為短暫行為。) I have finished my homework now. -Will somebody go and get Dr. White? -Hes already been sent for. 句子中如有過去時(shí)的時(shí)間副詞（如 yesterday, last, week, in 1960）時(shí)，不能使用現(xiàn)在完成時(shí)，要用過去時(shí)。

22、（錯(cuò)）Tom has written a letter to his parents last night. （對(duì)）Tom wrote a letter to his parents last night. （四）做題時(shí)常見錯(cuò)誤如下：1、易丟掉have/has例：He taken (take) the medicine before. 答案：has taken 解析：have/has 為助動(dòng)詞，起構(gòu)成時(shí)態(tài)的作用，是不能省略的。我們可以這樣記：“現(xiàn)在完成時(shí)態(tài)中，have/has 不可缺?！?、have與has易用混 例：I has never heard (hear) of that befor

23、e. 答案：have heard解析：現(xiàn)在完成時(shí)與一般現(xiàn)在時(shí)一樣也有單三人稱的變化，當(dāng)單三人稱作主語時(shí)用 has, 一般人稱作主語時(shí)用have3、延續(xù)性動(dòng)詞與短暫性動(dòng)詞易弄錯(cuò) 例：She has left (離開) for 2 hours.答案：has been away 解析：在肯定句中，與since或for引出的時(shí)間狀語連用的是延續(xù)性動(dòng)詞，不能是短暫性動(dòng)詞，但在否定句中短暫性動(dòng)詞也是可以的。E.g. I havent bought clothes for one year. 在此題中l(wèi)eave是短暫性動(dòng)詞，不能與for+時(shí)間段連用，須把它改成相應(yīng)的延續(xù)性動(dòng)詞。如stop be over等。

24、此題中l(wèi)eave要改成be away。這兩種詞的轉(zhuǎn)換是學(xué)習(xí)現(xiàn)在完成時(shí)需要注意的。(五)習(xí)題練習(xí)單項(xiàng)選擇。（前10個(gè)作為例題，共同完成，后10個(gè)為課后作業(yè)）1、Both his parents look sad .
