现在完成时 通常使用现在完成时的几种情况 1表示发生在过去对现在仍有影响的动作 ihavereadthebook 2表示过去发生一次或多次的动作 wehaveallplayedfootball 3表示过去开始的动作一直延续到现在 只能用于某些带有延续意义的动词 常与for since sofar等连用 hehastaughtheresincetenyearsago

现在完成时则强调某一发生在过去的动作与现在的关系 如对现在产生的结果或影响等 he work inthecityfortenyears worked hasworked 完成下列句子 i see thisfilmyesterday 强调看的动作发生过了 i see thisfilm 强调对现在的影响 电影的内容已经知道了 he be intheleagueforthreeyears 在团内的状态可延续 he join theleaguethreeyearsago 强调加入的动作发生在过去 saw haveseen hasbeen joined 一般过去时还是现在完成时 1they move tothesouthin1990and live theresincethen 2eric leave homelastyearand justcome back 3justin be awayfromhomeforseveraldays he disappear lastfriday 4they buy thishousethreeyearsagoandthey live heresincethen 5mybrother go toseemygrandpalastweek he visit himthreetimesthismonth moved havelived left hasjustcome hasbeen disappeared bought havelived went hasvisited 现在完成时与一般过去时常用的时间状语 一般过去时常与具体的时间状语连用 而现在完成时通常与模糊的时间状语连用 或无时间状语 一般过去时的时间状语 yesterday lastweek ago in1980 inoctober justnow inthepast等 皆为具体的时间状语 现在完成时的时间状语 for since already yet sofar uptonow ever never recently lately just inthepast years 等 皆不确定的时间状语 延续性与非延续性动词 判断正误 延续性动词常与for howlong since等引导的表示一段时间的状语或状语从句连用 一些非延续性动词如come go leave die join marry等如用于现在完成时 一般不可以与表示一段时间的时间状语连用 此时应改为意义相近的延续性动词来表达 1hehasdiedfor3years 2hehasbeendeadfor3years 3hedied3yearsago 4ithasbeen3yearssincehedied t f f f 注意 非延续性动词的否定形式可以与表示延续时间的状语连用 即动作不发生的状态是可以持续的 判断正误 ihavereceivedhisletterforamonth ireceivedthisletteramonthago ihaven treceivedhisletterforalmostamonth 错 对 对 比较since和for since用来说明动作起始时间 for用来说明动作延续时间长度 例如 ihavelivedhereformorethantwentyyears ihavelivedheresinceiwasborn 注意 并非有for时间状语的句子都用现在完成时 比较 i work hereformorethantwentyyears 我现在已不在这里工作 i work hereformanyyears 现在我仍在这里工作 注意 用句型转换的方法 很容易排除非延续动词在有for since结构的完成时中的误用 1 tomhasstudiedrussianforthreeyears tombegantostudyrussianthreeyearsago andisstillstudyingitnow 2 harryhasgotmarriedforsixyears harrybegantogetmarriedsixyearsago andisstillgettingmarriednow 第二句应改为harrygotmarriedsixyearsago 或harryhasbeenmarriedforsixyears worked haveworked 对 错 用于现在完成时的特殊句型1 itisthefirst secondtime that 结构中的从句部分 用现在完成时 例如 itisthefirsttimethati visit thecity thisisthefirsttime that i hear himsing 注意 itwasthethirdtimethattheboy be late 2 thisis 形容词最高级 that 结构 that从句要用现在完成时 例如 thisisthebestfilmthati ever see 典型例题 1 doyouknowourtownatall no thisisthefirsttimei here a wasb havebeenc camed amcoming 2 haveyou beentoourtownbefore no it sthefirsttimei here a even comeb even havecomec ever comed ever havecome havevisited haveheard hadbeen have
