法语Wordsandexpressions►现在完成时(一)1．现在完成时的构成现在完成时由“助动词have/has＋动词的过去分词”构成。规则动词的过去分词构成与动词过去式相同，如：finish—finished；不规则动词需要特殊记忆。2．现在完成时的句型结构①肯定句：主语＋have/has＋过去分词＋其他．②否定句：主语＋have/has＋not＋过去分词＋其他．③一般疑问句：Have/Has＋主语＋过去分词＋其他？肯定回答：Yes，主语＋have/has.否定回答：No，主语＋haven't/hasn't.我完成了/还没有完成家庭作业Ihave/haven'tfinishedmyhomework.你已经做完这项工作了吗？—Haveyoufinishedthework？是的，我已经做完了。/不，我还没有做完。—Yes，Ihave./No，Ihaven't.3．现在完成时的用法①现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在造成的结果或影响。eg：Mydaughterhasjustgoneout.我的女儿刚出去。I'msurewe'vemetbefore.我肯定我们以前见过面。Ididn'tfindmyIDcard.IthinkIhavelostit.我没找到我的身份证。我想我已经遗失了它。②表示持续到现在的动作或状态，往往和包括现在在内的表示一段时间的状语连用，如recently，already，just，lately，for...，since...，yet等。eg：Ihaven'theardfromherthesedays.这些日子我没有收到她的信。Theyhavebeenawayfortwoyears.他们离开已经两年了。IhavelivedheresinceIwasfive.自我五岁起我就住在这里了。4．现在完成时的标志词现在完成时常与already，yet，never，ever，before，just等连用。其中，already一般用于肯定句，yet常用于否定句和疑问句中。含有already的肯定句变否定句或疑问句时，要将already变为yet，并置于句末。eg：Therainhasalreadystopped.雨已经停了。→Therainhasn'tstoppedyet.雨还没停。(否定句)→Hastherainstoppedyet？雨已经停了吗？(疑问句)规则变化：Infinitive动词原形PastTense过去式变化规则looklooklookmovemovemovecarrycarrcarrstopstopstop一般动词，加ed以不发音的e结尾的动词，加d以“辅音+y”结尾的动词，变y为i，再加ed以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加ed动词过去分词的变化规则示例ededddPastParticiple过去分词ededppedyiedyi现在完成时：①Shehas

alreadycleaned

thefloor.

②Shecleanedtheflooryesterday.

现在完成时与一般过去时一、构成不同她已经打扫了地板。她昨天打扫了地板。一般过去时：主语+have/has+过去分词主语+动词过去式Ihavealreadyfinished

myhomework.Ifinisheditanhourago.现在完成时表示该事件是在现在之前的某一个时间里发生的，重点在于强调已完成动作对现在的影响。二、用法不同一般过去时表示在过去某一具体时间发生的事情。我已经完成家庭作业了，一小时前完成的。现在完成时可以和表示延续的时间状语连用。表示持续动作或状态的动词多是延续性动词。①Ihaven’tseenherthesedays.②I’vebeenatthisschoolforovertwoyears.

②Didyouwatchthatfilmlastweek

③Shecamebackyesterday.三、时间状语不同我这些天没见过她。你上周看那部电影了吗？她是昨天回来的。一般过去时常与表过去的具体的时间状语连用。我已经在这个学校呆了两年多了。当A问对方把自己的书放在何处时，他强调的是现在找不到了，故用现在完成时。但B的回答只是说明当时放的位置，故用一般过去时。A:WherehaveyouputmybookIcan'tfindit.B:Iputitonyourdeskyesterday.当没有明确的过去时间状语时，判断该用现在完成时还是一般过去时的标准是：看该行为是否对现在有影响，即该句所强调的是什么。A:WouldyouliketogoandseethefilmwithmetonightB:Sorry,Ihaveseenitalready.此时的现在完成时表示对结果的强调：“电影看过了，所以不想再看了”。二、用所给单词的适当形式填空。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、语法选择。Onceuponatime，therewasamaninChinacalledLordYe.__11__inthetownknewheloveddragons.Hehadbeautiful__12__ofdragonseverywhereinhishouse.Hehaddragonscarvedonthestonefloors.There__13__evendragonspaintedonthe__14__tablesandchairs，andonhiscupsandbowls.Also，dragons__15__onhisfavoritesilkrobe(长袍).Oneday，thedragoninheavenheardofLordYeandhislovefordragons.Thedragonwas__16__movedthathedecidedtothankLordYe，sothedragonleftheaven__17__avisittohim.(
