示一个在过去完成的动作,但现在完成时强调的是与现在的关系,如对现在产生的结果或影响等,属于现在时范围,谈论的是现在的情况。而一般过去时只表示动作在过去某一时刻发生,不表示和现在的关系,现在情况可能已发生变化。Whoopenedthedoor?(“谁开的门?”只强调过去开门这一动作,门现在可能已关上。)Whohasopenedthedoor?(“谁把门开了?”强调门现在依然还开着。)2、现在完成时不能与明确的过去时间状语连用,如:threedaysago,lastyear,yesterday,lastSunday,in2008等等。如句中有以上这些明确的过去时间状语,应用一般过去时。再有,过去发生的一个动作,如果现在情况已经发生的变化,也应用一般过去时。☆特别提醒:如果这些过去时间状语前有since,表示“自过去某一时间一直延续到现在”,应用现在完成时。 Hefinishedreadingthebookthedaybeforeyesterday. Iputmyrulerinmypencil-box,butIcan’tfinditnow. MycousinhasbeeninNanjingsince2009.3、since引导的时间状语从句后面用一般过去时,只有前面的主句才用现在完成时。Wehaveknowneachothersincewecametotheschooltwoyearsago.4、现在完成时不与when引导的特殊疑问句连用,when后只用一般过去时表示已发生的动作。但现在完成时可与where,why等疑问词连用。如:Wherehaveyoubeen?(你去过哪里了?) ----Thetrainhasleft. ----Whendidthetrainleave? 5、有些时间状语,如thismorning,thismonth,tonight等,既可以与一般过去时连用,又可以与现在完成时连用,但内涵不同。与一般过去时连用时,表示与“现在”无关,时间已成为过去。而与现在完成时连用,则表示包括“现在”在内。Isawhimthismorning.(时间已不在上午了。)Ihaveseenhimthismorning.(说话时间还是上午。)HelivedinNewYorkforeightyears.(他现在已经不在纽约住了。)HehaslivedinNewYorkforeightyears.(他现在还在纽约居住。)一、动词填空:1.
