我从去年开始学习英语。2)ShehaslivedinBeijingforfiveyears.

她住在北京已经五年了。注意:come,go,leave,arrive,buy,lose,receive,join,die,bury和marry等动词所表示的动作是一时的,不能延续的,

故不能与for…,since…等开头的表示一段时间的状语连用。不过,这些词用于否定句则可以与表示持续的时间状语连用，即动作的不发生是可以持续的。不能说:

*Hehascome

toBeijingfor

two

years.*Hehasboughtthatbookfor

three

weeks.*HehasjoinedtheArmyforoneandahalfyears.*Hisgrandmahasdied

for

nine

months.*Ihavereceivedhisletterforamonth.可以说:HehasbeeninBeijingfortwoyears.Hehashadthatbookforthreeweeks.Hehasbeeninthearmyforoneandahalfyears.Hisgrandmahasbeen

deadforninemonths.Ihaven't

receivedhisletterforalmostamonth.或者说：ItistwoyearssincehecametoBeijing.Itisthreeweekssinceheboughtthatbook.ItisoneandahalfyearssincehejoinedtheArmy.Itisninemonthssincehisgrandmadied.注意:

现在完成时不能和明确指出时间的状语(如:yesterday,last,year,in1976,twodaysago,justnow,whenshecamein等)连用，但可以和不明确指出时间的状语(如:already,yet,ever,never,sometimes,always,often,before,once,twice,recently,lately等)连用；也可以和表示包括现在在内的时间状语(如：today,thismorning,thisweek,thisyear等)连用。everjustalreadyyete.g.Haveyou_____beentoJapan?Ihave_____finishedmyhomework.Ihavefinishedmyhomework______.

Ihaven’tfinishedmyhomework____.B.just,already,yet,before/ever,never有此类副词时,常强调动作完成,不强调动作的持续.Shehasalreadyfinishedherwork.她已经把工作做完了。Ihaven’treadthestoryyet.我还没读过这个故事。Haveyoumethimbefore?你从前曾见过他吗？Lilyhas

alwaysbeenagoodstudent.Lily一直是个好学生。比较：Ihaveseenhimthismorning.我上午看见他了。(说话时在上午)Isawhimthismorning.今天上午我遇见了他。(说话时可能是下午或者晚上)Ithasbeencoldthiswinter.今天冬天一直很冷。(说话时仍是冬天)4.现在完成进行时和现在完成时都可以表示“从过去开始一直持续到现在”这一概念,有时两者可以互相代用,但前者多用于口语。在含义上如着重表示动作的结果时,多用现在完成时;如着重表示动作一直在进行,即动作的延续性时,则多用现在完成进行时。一般不能用于进行时的动词也不能用于现在完成时行时。

现在完成时：表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，不能和表示过去的时间状语连用（如：in1990，lastSunday等）。

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：have/has+V过去分词Ihavewaitedforhimformanytimes.我等他等了好几次了。Ihave

been

waiting

forhimforanhour.我等他等了一小时。Hehas

drunksixcupsofcoffee.

他喝了六杯咖啡。Hehas

been

drinkingcoffee.他一直在喝咖啡。改写句子1.Myfathercamebackfromthebookshopjustnow.Myfather______just______________thebookshop.2.HebegantolearnChinesein2001.He____________Chinesesince2001.3.Thefilmbegantwominutesago.Thefilm_________________sincetwominutesago.4.Hehashadthemotorbikefortwoyears.It’stwoyears______he________themotorbike.He________themotorbiketwoyears______.Twoyears____________sincehe______themotorbike.hasreturnedfromhaslearnedhasbeenon
