现在完成时和一般过去时的区别
现在完成时和一般过去时都表示过去完成的动作，但现在完成时强调与现在的关系，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，不表示与现在的关系，现在情况可能已发生变化。例如，“谁开的门？”只强调过去开门这一动作，门现在可能已关上。而“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“三天前”，“去年”，“昨天”，“上周日”，“在2008年”等等。如果句中有以上这些明确的过去时间状语，应用一般过去时。另外，如果过去发生的一个动作，现在情况已经发生了变化，也应用一般过去时。但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。例如，他前天读完了这本书。我把尺子放在铅笔盒里，但现在不到了。我表弟自2009年以来一直在南京。
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。例如，“你去过哪里了？”——“火车已经
开走了。”——“火车什么时候开的？”
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。例如，我们自两年前来到这所学校就认识了彼此。
有些时间状语，如“今天早上”，“这个月”，“今晚”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。
