Talk about;1 Have you played basketball?2 Have you finished your homework?3 Have you been to England?寫出下列動詞的過去分詞 work ( ) arrive( ) start ( ) live ( ) study ( ) stop ( ) carry ( ) plan ( ) Have ( ) keep ( )現(xiàn)在完成時的構(gòu)成: “have / has +動詞的過去分詞”,在人稱代詞后,have 和has??s為ve ,s ,否定縮寫 have not = havent ,has not = hasntworkedstartedarrivedlivedstudiedcarriedstoppedplannedhadkept1 現(xiàn)在完成時的主要用法及常用時間狀語 a 表示過去發(fā)生或已經(jīng)完成的某一動作對現(xiàn)在產(chǎn)生的影響或結(jié)果,常與already、never、ever、just、yet等時間狀語連用。 Then make your own sentences like this : eg :I have already done my exercise.b 表示過去已經(jīng)開始,持續(xù)到現(xiàn)在的動作或狀態(tài),可以和表示過去某一時刻延續(xù)到現(xiàn)在(含“現(xiàn)在”)的一段時間的狀語。如:today、these days、for two years、since 1984、since he came here等連用。2 巧記現(xiàn)在完成時的用法巧記現(xiàn)在完成時的用法 學(xué)習(xí)現(xiàn)在完成時,謂語結(jié)構(gòu)要記住學(xué)習(xí)現(xiàn)在完成時,謂語結(jié)構(gòu)要記住“have / has +過去分詞過去分詞”主要用法有兩個:過去發(fā)生的動作對現(xiàn)在產(chǎn)生的影響或結(jié)果,主要用法有兩個:過去發(fā)生的動作對現(xiàn)在產(chǎn)生的影響或結(jié)果,just,already常用著,過去動作或狀態(tài),一直延續(xù)到現(xiàn)在,常用著,過去動作或狀態(tài),一直延續(xù)到現(xiàn)在,for和和since把時間帶。如:把時間帶。如:I have known Lilei for three years.Now ,boys and girls,tell us your sentences like this- 現(xiàn)在完成時/The Present Perfect Tense試一試,用所給詞的正確形式填空1 I (live)here since I was ten years old. 2 I (live)here in 1998.3 - you your breakfast?-Yes,I have. -When you it?- 30 minutes ago.注意現(xiàn)在完成時的幾個特殊方面:(一)現(xiàn)在完成時與一般現(xiàn)在時的區(qū)別have livedlivedHave haddid have 現(xiàn)在完成時表示過去發(fā)生或已經(jīng)完成的某一動作對現(xiàn)在產(chǎn)生現(xiàn)在完成時表示過去發(fā)生或已經(jīng)完成的某一動作對現(xiàn)在產(chǎn)生的影響或結(jié)果,強(qiáng)調(diào)的是現(xiàn)在的情況。所以它不能和表示過去時的影響或結(jié)果,強(qiáng)調(diào)的是現(xiàn)在的情況。所以它不能和表示過去時間狀語連用;而一般過去時只單純表示過去的動作或狀態(tài),和現(xiàn)間狀語連用;而一般過去時只單純表示過去的動作或狀態(tài),和現(xiàn)在不發(fā)生關(guān)系,可以和表示過去的時間狀語連用。在不發(fā)生關(guān)系,可以和表示過去的時間狀語連用。一)現(xiàn)在完成時與一般現(xiàn)在時的句型轉(zhuǎn)換eg:I have studied English for three years -I studied English three years ago -It is three years since I studied English(二)表示短暫動作的瞬間性動詞,如come、go、buy等的完成時態(tài)就不能與for、 since 等表示一段時間的狀語連用,但可以與這類詞相應(yīng)的延續(xù)性動詞或短語連用。試一試,改錯 1 I have come to Jianyang for ten years . ( ) 2 His father has died since he was five years old . ( )have been inhas been dead 瞬間動詞的用法口訣;現(xiàn)在完成在瞬間,非延只連時間點(diǎn), 終止 須轉(zhuǎn)換,否定方可碰一段說明:1 瞬間動詞又叫非延續(xù)性動詞或終止性動詞,它可以有現(xiàn)在完成時態(tài),但不可以接一段時間;如果要接一段時間,就必須把它轉(zhuǎn)換成相應(yīng)的延續(xù)性動詞。2 瞬間動詞在完成時態(tài)中的否定式中可以接一段時間。 類似的轉(zhuǎn)換還有:fall asleepbe asleep move therebe there open be open 等 巧記巧記10個瞬間性動詞的轉(zhuǎn)換個瞬間性動詞的轉(zhuǎn)換 “開始離去借來還,出生入死買到家開始離去借來還,出生入死買到家”1 beginbe on6 returnbe back2 leavebe away from7 joinbe in3 gobe off8 diebe dead4 borrowkeep9 buyhave5 comebe here10 arrivebe herehave /has been to和和have / has gone to 的用法區(qū)別的用法區(qū)別 1 “ Have /has been to+地名地名 ”表示曾經(jīng)去過某地,說話時已經(jīng)回到說話地點(diǎn), 常與once 、twice、ever、never 等時間連用。2 “have / has gone to +地名地名 ”表示去某地了,現(xiàn)在沒有回答,人不在說話地點(diǎn)。 巧記巧記: been to been to ,gone togone to 意不同,兩者用法要記清;意不同,兩者用法要記清; have been tohave been to + 地名,曾經(jīng)到過某地行;地名,曾經(jīng)到過某地行; have gone tohave gone to + 地點(diǎn),到某地去了一走遠(yuǎn)。地點(diǎn),到某地去了一走遠(yuǎn)。用have /has been to和和have / has gone to填空 Hi,Lucy, you ever Beijing? No,I . What about your sister,Lily? Oh,she Chengdu, she will come back next week. Ok,thanks. Youre welcome.have been to haventhas gone toChoose the best answer1 What a nice watch !How long you it?
