TreasureIslandyet?Yes,shehas.Shethinksit’sfantastic.Haveyoudecidedwhichbooktowriteaboutyet?Yes,Ihave.I’vealreadyfinishedreadingit.Itwasreallygood.一、现在完成时的基本结构现在完成时由“助动词have/has+过去分词”构成，其基本句式结构为：①肯定句：主语+have/has+过去分词+其他.Ihaveseenthisfilm.②否定句：主语+have/hasnot+过去分词+其他.Ihavenotseenthisfilm.现在完成时态（1）和主语一致have/has常可缩略为-’ve/-’sPresentation③一般疑问句：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.—Haveyouseenthefilm?—Yes,Ihave./No,Ihaven’t.havenot=haven’t;hasnot=hasn’t二、过去分词的变化1.规则变化（与动词过去式规则一样，此类称作规则动词）一般在词尾直接加-ed以不发音的e结尾的，加-d以“辅音字母+y”结尾的变y为i加-ed重读闭音节以一个辅音字母结尾的，双写这个辅音字母后加-edwork→workedslice→slicedstudy→studiedstop→stopped2.

不规则变化（此类称作不规则动词，有很多）原形过去式过去分词bewas/werebeenhavehadhadchoosechosechosenputputputrunranrun参看课本P136-137IrregularVerbs（不规则动词表）三、现在完成时的用法1.表示过去发生或已经完成的动作对现在造成的影响或结果。常和just（刚刚）、already（已经）、yet（还，仍然）、ever（曾经）、never（从未）、before（以前）、so

far（到目前为止）等连用。—Haveyouhadyourbreakfastyet?—Yes,Ihave.I’vejusthadit.—Haveyoueverheardofthissong?—No.I’veneverheardofitbefore.Juliahascollectedover100beautifulhairclipssofar.现在完成时用法1：表示过去发生或已经完成的动作对现在造成的影响或结果；pastIhadbreakfast.I’mnothungrynow.

presentIhavealreadyhadbreakfast.（早餐过去吃的，现在不饿。）图示法表示2.现在完成时还可以表示过去某一时间开始并一直持续到现在的动作或状态，常与“for+时间段”或“since+时间点/从句”连用，这时要用延续性动词。Theyhaveworkedinthiscompanyfor30years.Hehasbeeninthearmysince2016.（错：Hehasjoinedthearmysince2016.）【特别提醒】如果要对for或since短语提问，疑问词用howlong。—Howlonghaveyoulivedinthisarea?—Foratleast10years.现在完成时用法2：表示过去某一时间开始并一直持续到现在的动作或状态。图示法表示pastImovedherein1990.Istilllivehere.presentIhave

livedherefor30years.（30年来一直生活在这里）四、already与yet在现在完成时中的用法辨析yet常用于否定句或疑问句句末。用于表示某事尚未发生或某情形尚未出现，或用于询问某事是否已经发生。Hehasn’tfinishedthebookyet.Haveyouseenhimyet?already常用于肯定句中，用于强调某事已经开始出现；也可用于疑问句中，表示因某事的发生早于预料而感到吃惊。Theyhavealreadyknowneachother.Haveyoueatenallthatfoodalready?五、现在完成时

VS.

一般过去时现在完成时表示过去发生的某一动作对现在造成的影响或结果，强调的是现在的情况，因此不能和表示过去的时间状语连用。Ihavealreadydonemyhomework.（不能用lastnight等）I’vebeentoParisbefore.（不能用lastyear等）2.一般过去时只表示过去的动作和状态，与现在无关。可以和表示过去的时间状语连用。Ididmyhomeworklastnight.WhendidyougotoParis?（when一定不要和现在完成时连用）3.

日常对话中通常两种时态配合使用，开始提到一件事做没做或发生过时用现在完成时，说起这件事具体情形时用一般过去时。—HaveyoubeentoJapan?—Yes,Ihave.Iwenttherelastyear.—Whodidyougowith?—…1.A:Wouldyoulikesomethingtodrink?B:No,thanks.________________________.(just/drinksometea)2.A:Iheardyoulostyourkey._______________________?(find)B：No,notyet.4aUsethewordsinbracketstocompletetheconversations.Tip:Findthekeywordstoidentifywhichtensetouse.I’vejustdrunksometeaHaveyoufoundityet3.A:DoyouknowwhenTomisleaving?B:________________________________.(already/leave)A:When_____________________?(leave)B:Thismorning.4.A:Isyoursistergoingtothemovieswithustonight?B:No.___________________________.(already/seethefilm)HehasalreadyleftdidheleaveShehasalreadyseenthefilm5.A:Whatdoyourparentsthinkaboutourplan?B:I_____________________________.(not/tellthem/yet)havenot/haven’ttoldthemyet4bFillintheblankswiththecorrectformsofthewordsinbrackets.Sally______(love)reading.Inthemorning,shereadsthenewspaperandintheeveningshereadsbooks.She______already_______(read)morethan100differentbooks!Herfavoritekindofbooksissciencefiction.Shefictionn.小说sciencefiction科幻小说（或影片等）loveshasreadTip:Findthekeywordstoidentifywhichtensetouse.isinterestedinscienceandtechnologyandlovestoimaginewhattheworld_________(be)likein50years.She________(finish)readingabookaboutrobotslastweek
