一、時態講解：現在完成時（1）構成：現在完成時由助動詞have+過去分詞構成，助動詞have有人稱和數的變化。第三人稱單數用has，其余用have.現在完成時的否定式直接在助動詞后面加上not、疑問式是把助動詞提到主語之前。以study為例，其否定式、疑問式和簡單回答形式如下：否定式疑問式Ihavenot(haven't)studied..HaveIstudied.?Youhavenot(haven't)studied..Haveyoustudied.?Hehasnot(hasn't)studied..Hashestudied.?否定疑問式簡單回答（肯定/否定）HaveInot(Haven'tI)studied.?Yes,youhave.No,youhaven't.Haveyounot(Haven'tyou)studied.?Yes,Ihave.No,Ihaven't.Hashenot(Hasn'the)studied.?Yes,hehas.No,hehasn't.2）用法：現在完成時通常表示在說話之前已經完成的動作或存在的狀態。說話人強調的是該動作或狀態對現在的結果或影響。Mydaughterhasjustgoneout.我女兒剛出去。I'msurewe'vemetbefore.我肯定我們以前見過面。Shehasarrived.她到了。表示持續到現在的動作或狀態，往往和包括現在在內的表示一段時間的狀語連用，如recently,already,just,lately,for..since...,yet等。如：Ihaven'theardfromherthesedays.這些日子我沒有收到她的信。Wehaven'tseenyourecently.最近我們沒有見到你。Theyhavebeenawayfortwoyears.他們離開已經兩年了。ShehasbeenwithussinceMonday.★注意：a)since和for的區別since后接時間點，如1993，lastterm,yesterday,thetimeIgottherefor后接一段時間，表示“長達多久”，如tenyears,awhile,twodays等。Exercise:用since和for填空JimhasbeeninIrelandMonday.JillhasbeeninIrelandthreedays.HisaunthaslivedinAustralia15days.Maryisinheroffice.Shehasbeenthere7o'clock.Indiahasbeenanindependentcountry1974.Thebusislate.They'vebeenwaiting20minutes.Nobodylivesinthosehouses.Theyhavebeenemptymanyyears.Mikehasbeenillalongtime.HehasbeeninhospitalOctober.2)表示短暫意義的動詞如arrive,leave,borrow,buy,begin,start,die等，在完成時當中不能和表示一段時間的狀語連用，因為它們表示的動作不可能持續。因此，不能說：Hehascomeherefor2weeks.xTheoldmanhasdiedfor4months.xTheyhaveleftonlyfor5minutes.x以上三句話可以改為：Hehasbeenherefor2weeks.Theoldmanhasfor4months.Theyhaveonlyfor5minuteshave(has)been和have(has)gone的區別：表示“曾到過某地”要用“have(has)been”;表示“已經去某地”要用“have(has)gone”。試比較：Wherehashebeen?他剛才到哪里去了？(已經回來了)Wherehashegone?他上哪兒去了？(人不在)TheyhavebeentoCanada.他們到過加拿大。(現在已經不在加拿大)TheyhavegonetoCanada.他們到加拿大去了。(可能在路上和已經到加拿大).現在完成時不能和表示過去的時間狀語連用，如yesterday,lastyear,in1976,twodaysago,justnow,whenIcamein,但可以和already,yet,sometimes,always,often,before,lately,recently,once,twice,ever,never等連用。例如：Shehasalreadycome.她已經來了。Ihaven'treadityet.我還沒讀過這個。Ihavemethimbefore.我從前曾見過他。MaHonghasalwaysbeenagoodstudent.馬紅一直是個好學生。Ihaveoftenseenhiminthestreet.我經常在街上看見他。TheyhaveneverbeentoYan'an.他們從未去過延安。Ihaven'tseenhimlately.我近來沒看到他。irreguiarVerbsBaseFormPastFormPastParticiplebearborebornbeatbeatbeatenbecomebecamebecomeblowblewblownbringbroughtbroughtbuildbuiltbuiltbuyboughtboughtcatchcaughtcaughtchoosechosechosencomecamecomedodiddonedrinkdrankdrunkdrivedrovedriven
