示过去发生或已经完成的某一动作对现在造成的影响或结果，或从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，常用for禾口since表示一段时间的状语或sofar，noJ，today，thisweek(month，year)等表示包括现在时间在内的状语。不能和表示过去的时间状语连用(如：in1990,lastSunday等)。例如：HehasstudiedEnglishfor5years.HehasstudiedEnglishsince2001.NowIhavefinishedthework.注意：表过去某一时间发生的动作或状态一直延续到现在（强调现在），动作或状态一般是延续性的，因此要用表延续性的动词或表状态的动词。表示短暂时间动作的词，如：come，go，die，marry，buy等的完成时不能与for，sinee等表示一段时间的词连用。也不能用于howlong引导的疑问句中。如不能说：Hehasborrowedthebookfortwomonths.(x)但可以说：Hehaskeptthebookfor2months.或：Ithasbeen2monthssinceheborrowedthebook.或：Twomonthshaspassedsinceheborrowedthebook.这些瞬间动词常与它对应的可以表示时间段的词语进行互换。become—bebegin(start)—beonleave--beawayborrow—keepbuy—haveopen—beopendie—bedeadcome--behere/ingoout—beoutjoin--beamember/beinbegintostudy-study注明：非延续性动词在否定结构中可用于现在完成时态:Ihaven'ugotanythingfortwodays.2、现在完成时的结构：have/has+过去分词否定结构：haven't/hasn't+过去分词一般疑问句中:Have/Has+主语+动词的过去分词3、一般过去时：一般过去时只表示过去的动作或状态，和现在不发生关系（即动作或状态在现在已经结束），它可以和表示过去的时间状语连用。现在完成时与一般过去时的区别：现在完成时用来表示之前已发生或完成的动作或状态，其结果的确和现在有联系。动作或状态发生在过去，但它的影响现在还存在；而一般过去时表示过去的事实，不表示和现在的关系。IhavejustbeentoLondon.Iwenttherelastmonth.我刚去过伦敦，是上个月去的。过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。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,具体的时间状语共同的时间状语:thismorning,tonight,thisApril,now,once，before,already,recently,lately现在完成时的时间状语for,since,sofar,ever,never,just,yet,till/until,uptonow,inpastyears,always,3•现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live,teach,learn,work,study,know.过去时常用的非持续性动词有come,go,leave,start,die,finish,become,getmarried等。举例：Isawthisfilmyesterday.（强调看的动作发生过了。）Ihaveseenthisfilm.（强调对现在的影响，电影的内容已经知道了。Whydidyougetupsoearly?（强调起床的动作已发生过了。）Whohasn'thandedinhispaper?（强调有卷子，可能为不公平竞争。）ShehasreturnedfromParis.她已从巴黎回来了。Shereturnedyesterday.她是昨天回来了。HehasbeenintheLeagueforthreeyears.（在团内的状态可延续）HehasbeenaLeaguememberforthreeyears.（是团员的状态可持续）HejoinedtheLeaguethreeyearsago.（三年前入团，joined为短暂行为。）Ihavefinishedmyhomeworknow.---WillsomebodygoandgetDr.White?---He'salreadybeensentfor.句子中如有过去时的时间副词（如yesterday,last,week,in1960时，不能使用现在完成时，要用过去时。（错）Tomhaswrittenalettertohisparentslastnight.（对）Tomwrotealettertohisparentslastnight.二、动词的过去分词的
