初中英语现在完成时与一般过去时的区别.docx

1、现在完成时与一般过去时的区别1.共同点：现在完成时和一般过去时都表示一个在过去完成的动作。2.区别：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。Who opened the door? (“谁开的门？”只强调过去开门这一动作，门现在可能已关上。)Who has opened the door? (“谁把门开了？”强调门现在依然还开着。)现在完成时不能与明确的过去时间状语连用，如：three days ago, last year, yesterday, la

2、st Sunday, 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。 He finished reading the book the day before yesterday. I put my ruler in my pencil-box, but I cant find it now. My cousin has been in Nanjing since 2009.现在完成时不与when引导的特

3、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：Where have you been? (你去过哪里了？) -The train has left. -When did the train leave?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。We have known each other since we came to the school two years ago.有些时间状语，如this morning, this month, tonight等，既可以与一般过去时连用，又可以与现在完

4、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。I saw him this morning. (时间已不在上午了。)I have seen him this morning. (说话时间还是上午。)He lived in New York for eight years. (他现在已经不在纽约住了。)He has lived in New York for eight years. (他现在还在纽约居住。)同步练习动词填空：1. I _(see)Tom last Friday.2. _you _(go)to the G
