现在完成与过去式的区别课件

现在完成时态的用法及与一般过去时态的区别知识讲解--知识点：现在完成时的构成：助动词have（has）+过去分词，1．表示过去发生或完成的某一动作对现在造成的影响或结果。例如：Ihavejustcleanedmyclothes.我刚洗过衣服。（“洗衣服”是发生在过去的动作，对现在造成的结果是“衣服干净了”）现在完成时常用的时间状语有：already（”已经”用于肯定句的中间和末尾处）never(“从不”用于中间处)ever（”曾经”用于疑问句和肯定句的中间处）just (“刚刚”用于中间处)yet(“已经”用于疑问句的末尾处/“还”用于否定句的末尾处)或不加任何的时间状语，但不能和表示过去的时间状语连用.现在完成时与一般过去时的用法比较现在完成时表示过去的动作一直延续到现在甚至会继续下去或表示过去的动作对现在造成的影响；一般过去时表示动作发生的时间在过去。试比较：Theplanehasarrived.飞机已经来了。（说明现在的情况：飞机在这儿）Theplanearrivedaquarterago.飞机是一刻中以前来的。（强调动作发生的时间在过去）Ihavetaughthereforfifteenyears.我在这儿已经教了十五年。（表示十五年前的动作一直延续到现在，还可能会继续。）Itaughthereforayear.我过去在这儿教过一年。（表示“我“现在已经不在这儿任教了）用过去时或现在完成时填空：1.“_________you__________(have)lunch?”“Yes.”“When________you__________(have)it?”“I____________(have)itat12:00.”2.“_________you__________(write)alettertoyourauntyet?”“Yes,I___________.I________________(write)onelastweek.”3.“_________he___________(finish)hishomework?”“Notyet.”4.“_________theyever__________(be)abroad?”“Yes,justonce.”5.Yourfather_________just___________(finish)hiswork.6.Yourfather_________(finish)hisworkjustnow.7.LasttermI__________(learn)manyEnglishwords.8.They____________(notread)theinterestingbooksyet.9.He_____________never____________(go)tothesciencemuseum.10.____________youever____________(drink)coke?11.“____________you_____________(buy)adictionary?““Yes,I__________.”“Where__________you_____________(buy)it?”“I___________(buy)itinabookstore.”“When___________you_____________(buy)it?”“Yesterday.”HavehaddidhavehadHavewrittenhavewtoteHavebeenhasfinishedfinishedLearnt/dhavenotreadhasbeenHavedrunkHavehadhavedidbuyboughtdidbuyHavefinished练习：用since和for填空1)______twoyears 2)_______twoyearsago3)_______lastmonth 4)______1999 5)_______yesterday 6)_______4o’clock7)______4hours 8)_______anhourago 9)_______wewerechildren10)_____lunchtime 11)______shelefthere1.HehaslivedinNanjing________theyearbeforelast.2.I’veknownhim__________wewerechildren.3.OurteacherhasstudiedJapanese_________threeyears.4.Shehasbeenawayfromthecity___________abouttenyears.5.It’sabouttenyears__________sheleftthecity.sinceforsincesincesincesinceforsincesinceforsincesincesinceforforsince短暂性转换延续性arriveat/insw.→beinsw./atschool/athome/onthefarmgetto/reachsw.→beherecome/go/movetosw.→bethere1)
