has\havebeendoing2.用法1)叙述某一动作从过去开始一直继续到现在仍在继续之中或刚刚停止。经常与for,since,allmorning/day/week用在一起。Youhavebeenstudyingforfourstraighthours.Whydon’tyoutakeabreak?Thetelephonehasbeenringingforalmostaminute.Whydoesn’tsomeoneanswerit?2)叙述“最近”一直从事的工作或活动。

lately,recentlyWhat’sthematter?Youreyesareredandpuffy.Have

you

been

crying?你是不是一直在哭?3)表示重复动作。有时现在完成进行时所表示的动作并不是在一直不停地进行,而是在断断续续地重复。Ihavebeenknocking.Idon’tthinkanybody’sin.我一直在敲门,我想没人在里面。You’ve

been

sayingyoucansucceedforfiveyears.5年来你一直在说你能成功。Ihavebeenwritingletterssincebreakfast.我从早餐起就一直在写信。4)表示“刚才、近来”发生的动作,一般不再继续。此时一般通过上下文的语境进行判断。Myhandsaredirty.I’vebeenpaintingthedoor.我的手很脏,我一直在漆门。Whathaveyoubeen

我找了你老半天。现在完成进行时与现在完成时的区别现在完成时表示结果,其动作发生在过去，但对现在有影响;而且现在完成时也可表示动作的持续。而现在完成时表示比较长久的动作和状态,而现在完成进行时表示较短暂的动作和状态,而且强调持续性或未暂停性。Hehasn’tworkedforyears.他多年来一直没有工作。Ihaven’t

been

workingverywellrecently.我最近工作不太顺利。Theyhave
