法語(yǔ)Wordsandexpressions?現(xiàn)在完成時(shí)(一)1．現(xiàn)在完成時(shí)的構(gòu)成現(xiàn)在完成時(shí)由“助動(dòng)詞have/has＋動(dòng)詞的過(guò)去分詞”構(gòu)成。規(guī)則動(dòng)詞的過(guò)去分詞構(gòu)成與動(dòng)詞過(guò)去式相同，如：finish—finished；不規(guī)則動(dòng)詞需要特殊記憶。2．現(xiàn)在完成時(shí)的句型結(jié)構(gòu)①肯定句：主語(yǔ)＋have/has＋過(guò)去分詞＋其他．②否定句：主語(yǔ)＋have/has＋not＋過(guò)去分詞＋其他．③一般疑問(wèn)句：Have/Has＋主語(yǔ)＋過(guò)去分詞＋其他？肯定回答：Yes，主語(yǔ)＋have/has.否定回答：No，主語(yǔ)＋haven't/hasn't.我完成了/還沒(méi)有完成家庭作業(yè)Ihave/haven'tfinishedmyhomework.你已經(jīng)做完這項(xiàng)工作了嗎？—Haveyoufinishedthework？是的，我已經(jīng)做完了。/不，我還沒(méi)有做完?！猋es，Ihave./No，Ihaven't.3．現(xiàn)在完成時(shí)的用法①現(xiàn)在完成時(shí)通常表示在說(shuō)話之前已經(jīng)完成的動(dòng)作或存在的狀態(tài)。說(shuō)話人強(qiáng)調(diào)的是該動(dòng)作或狀態(tài)對(duì)現(xiàn)在造成的結(jié)果或影響。eg：Mydaughterhasjustgoneout.我的女兒剛出去。I'msurewe'vemetbefore.我肯定我們以前見(jiàn)過(guò)面。Ididn'tfindmyIDcard.IthinkIhavelostit.我沒(méi)找到我的身份證。我想我已經(jīng)遺失了它。②表示持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)，往往和包括現(xiàn)在在內(nèi)的表示一段時(shí)間的狀語(yǔ)連用，如recently，already，just，lately，for...，since...，yet等。eg：Ihaven'theardfromherthesedays.這些日子我沒(méi)有收到她的信。Theyhavebeenawayfortwoyears.他們離開(kāi)已經(jīng)兩年了。IhavelivedheresinceIwasfive.自我五歲起我就住在這里了。4．現(xiàn)在完成時(shí)的標(biāo)志詞現(xiàn)在完成時(shí)常與already，yet，never，ever，before，just等連用。其中，already一般用于肯定句，yet常用于否定句和疑問(wèn)句中。含有already的肯定句變否定句或疑問(wèn)句時(shí)，要將already變?yōu)閥et，并置于句末。eg：Therainhasalreadystopped.雨已經(jīng)停了?！鶷herainhasn'tstoppedyet.雨還沒(méi)停。(否定句)→Hastherainstoppedyet？雨已經(jīng)停了嗎？(疑問(wèn)句)規(guī)則變化：Infinitive動(dòng)詞原形PastTense過(guò)去式變化規(guī)則looklooklookmovemovemovecarrycarrcarrstopstopstop一般動(dòng)詞，加ed以不發(fā)音的e結(jié)尾的動(dòng)詞，加d以“輔音+y”結(jié)尾的動(dòng)詞，變y為i，再加ed以一個(gè)輔音字母結(jié)尾的重讀閉音節(jié)動(dòng)詞，雙寫(xiě)詞尾輔音字母，再加ed動(dòng)詞過(guò)去分詞的變化規(guī)則示例ededddPastParticiple過(guò)去分詞ededppedyiedyi現(xiàn)在完成時(shí)：①Shehas

alreadycleaned

thefloor.

②Shecleanedtheflooryesterday.

現(xiàn)在完成時(shí)與一般過(guò)去時(shí)一、構(gòu)成不同她已經(jīng)打掃了地板。她昨天打掃了地板。一般過(guò)去時(shí)：主語(yǔ)+have/has+過(guò)去分詞主語(yǔ)+動(dòng)詞過(guò)去式Ihavealreadyfinished

myhomework.Ifinisheditanhourago.現(xiàn)在完成時(shí)表示該事件是在現(xiàn)在之前的某一個(gè)時(shí)間里發(fā)生的，重點(diǎn)在于強(qiáng)調(diào)已完成動(dòng)作對(duì)現(xiàn)在的影響。二、用法不同一般過(guò)去時(shí)表示在過(guò)去某一具體時(shí)間發(fā)生的事情。我已經(jīng)完成家庭作業(yè)了，一小時(shí)前完成的。現(xiàn)在完成時(shí)可以和表示延續(xù)的時(shí)間狀語(yǔ)連用。表示持續(xù)動(dòng)作或狀態(tài)的動(dòng)詞多是延續(xù)性動(dòng)詞。①I(mǎi)haven’tseenherthesedays.②I’vebeenatthisschoolforovertwoyears.

②Didyouwatchthatfilmlastweek

③Shecamebackyesterday.三、時(shí)間狀語(yǔ)不同我這些天沒(méi)見(jiàn)過(guò)她。你上周看那部電影了嗎？她是昨天回來(lái)的。一般過(guò)去時(shí)常與表過(guò)去的具體的時(shí)間狀語(yǔ)連用。我已經(jīng)在這個(gè)學(xué)校呆了兩年多了。當(dāng)A問(wèn)對(duì)方把自己的書(shū)放在何處時(shí)，他強(qiáng)調(diào)的是現(xiàn)在找不到了，故用現(xiàn)在完成時(shí)。但B的回答只是說(shuō)明當(dāng)時(shí)放的位置，故用一般過(guò)去時(shí)。A:WherehaveyouputmybookIcan'tfindit.B:Iputitonyourdeskyesterday.當(dāng)沒(méi)有明確的過(guò)去時(shí)間狀語(yǔ)時(shí)，判斷該用現(xiàn)在完成時(shí)還是一般過(guò)去時(shí)的標(biāo)準(zhǔn)是：看該行為是否對(duì)現(xiàn)在有影響，即該句所強(qiáng)調(diào)的是什么。A:WouldyouliketogoandseethefilmwithmetonightB:Sorry,Ihaveseenitalready.此時(shí)的現(xiàn)在完成時(shí)表示對(duì)結(jié)果的強(qiáng)調(diào)：“電影看過(guò)了，所以不想再看了”。二、用所給單詞的適當(dāng)形式填空。6．We___________(hear)ofthatplacebutwehaven'tbeenthere.7．I'msogladthatIhave________(finish)nearlyhalfofthetestnow.8．Mycousin_____________(notdecide)wheretogoonholidayyet.9．—DoesMr.Whitestilllivehere—No，hehas________(move)toParisalready.10．William___________(write)sixbooksalready，andallofthemarebestsellers.haveheardfinishedhasn'tdecidedmovedhaswrittenUsethewordsinbracketstocompletetheconversations.4a1.A:WouldyoulikesomethingtodrinkB:No,thanks._______________________.(just/drinksometea)2.A:Iheardyoulostyourkey._________________(find)B:No,notyet.3.A:DoyouknowwhenTomisleavingB:_________________.(already/leave)A:When____________(leave)B:Thismorning.4.A:IsyoursistergoingtothemovieswithustonightB:No.__________.(already/seethefilm)5.A:WhatdoyourparentsthinkaboutourplanB:I___________________.(not/tellthem/yet)I’vejustdrunksometeaP602.A:Iheardyoulostyourkey.____________________(find)B:No,notyet.3.A:DoyouknowwhenTomisleavingB:_________________.(already/leave)A:When____________(leave)B:Thismorning.4.A:IsyoursistergoingtothemovieswithustonightB:No.__________________________.(already/seethefilm)5.A:WhatdoyourparentsthinkaboutourplanB:I___________________.(not/tellthem/yet)HehasalreadyleftdidheleaveShehasalreadyseenthefilmhaven’ttoldthemyetHaveyoufoundityetCheckyouranswers.Fillintheblankswiththecorrectformsofthewordsinbrackets.4bSally_____(love)reading.Inthemorning,shereadsthenewspaperandintheeveningshereadsbooks.She___already____(read)morethan100differentbooks!Herfavoritekindofbooksissciencefiction.Sheisinterestedinscienceandtechnologyandlovestoimaginewhattheworld_______(be)likein50years.She_______(finish)readingabookaboutrobotslastweekand_________(write)abookreportaboutitnextweekforherFrenchclass.Everytimesheisinthelibrary,Sallylooksatthemanybooksshe__________(notread)yetandshecan’twaittoreadthem!loveshasreadwillbefinishedwillwritehasn’treadP60三、語(yǔ)法選擇。Onceuponatime，therewasamaninChinacalledLordYe.__11__inthetownknewheloveddragons.Hehadbeautiful__12__ofdragonseverywhereinhishouse.Hehaddragonscarvedonthestonefloors.There__13__evendragonspaintedonthe__14__tablesandchairs，andonhiscupsandbowls.Also，dragons__15__onhisfavoritesilkrobe(長(zhǎng)袍).Oneday，thedragoninheavenheardofLordYeandhislovefordragons.Thedragonwas__16__movedthathedecidedtothankLordYe，sothedragonleftheaven__17__avisittohim.(
