现在完成时通常和表示一段时间的时间状语连用。这样的时间状语有“for＋时间段”“since＋过去的时间点”以及“since＋表示过去的从句”。[探究]e.g.Myunclehasworkedatthisfactoryfortenyears.=Myunclehasworkedatthisfactorysincetenyearago.I’ve

lived

here

since

1990．自从1990年以来我就住在这里。

I

haven’t

seen

him

for

three

years.

我三年没有看见他了。

瞬间动词的肯定式不能和时间段连用。但其否定式可以和时间段连用。因为，其否定式表示的是一种状态，而状态总是可以延续的。如：Ihaven’tseenhimforalongtime.

我很久没见到他了。

Hehasn’tcomehereforsometime.

他有段时间没来了。

Ihaven’theardfromhersincesheleft.

自她离开以后，我一直没收到她的来信。[拓展]

短暂性动词在肯定句、疑问句中不能与时间段连用，如become,begin,buy,borrow,arrive,come,die,fall,finish,go,join,leave,marry等。为了表述这种意思，我们常用相应的延续性动词have,keep等来代替非延续性动词。如：我买这本书一周了。Ihaveboughtthebookforaweek.(×)Ihavehadthebookforaweek.(√)Themoviehasbeenonfortenminutes.Ihavehadthecarforthreemonths.Shehaskeptmystorybooksincelastweek.例:下面是句子的同义句转换,将原句一般过去时改成现在完成时Hewenttoschooltwohoursago.(一般过去时)Iborrowedthebookfivedaysago.getto/arrivein(at)\reach-bein+地点Hehasbeeninschoolfortwohours.(现在完成时，将gotoschool变为beinschool,for+时间段)Hehasbeeninschoolsincetwohoursago.(现在完成时，since跟过去的时间点)borrow借(短暂)-keep保存(延续)Ihavekeptthebookforfivedays.Ihavekeptthebooksincefivedaysago.Heboughtthebikethreeyearsago.2.Shefellasleeponehourago.3.Mysisterbecameanurseoneyearago.Hehashadthebikeforthreeyears.buy买(短暂)—have\own拥有(延续)Hehashadthebikesincethreeyearsago.fallasleep入睡(短暂)—beasleep睡着的(状态)Shehasbeenasleepforonehour.Shehasbeenasleepsinceonehourago.become变成(短暂)—be+名词(延续)Mysisterhasbeenanurseforoneyear.Mysisterhasbeenanursesinceoneyearago.JimisinJapan.Hearrivedtherethreedaysago.
