beforeTinareachedthestation.過去完成時的構成：過去完成時的謂語由“助動詞had+過去分詞”構成。否定式為“hadnot+過去分詞”,hadnot縮寫為hadn't。過去完成時的用法：1)表示一個動作或狀態(tài)在過去某一時間或動作之前已經完成，發(fā)生在“過去的過去”。這個過去的時間可以用by，before等介詞短語或者一個時間狀語從句來表示。e.g.WhenIwokeup,ithadstoppedraining.

我醒來時，雨已經停了。2)表示某一動作或狀態(tài)在過去某時之前已經開始，一直延續(xù)到這一過去的時間。常用表延續(xù)的時間狀語如：bytheendof+過去的時間點，bythetime+從句等。e.g.Bytheendoflastyear,shehadworked

inthefactoryfortwentyyears.

到去年年底，她已經在這家工廠工作20年了。PastPerfectTense1.過去完成時的構成：_____+___________2.過去完成時表示：________________________________________________________________________3.過去完成時常與______________________等引導的時間狀語連用。had過去分詞when,before,bythetime過去某一時刻或動作之前已經發(fā)生或完成的動作?，F在完成時與過去完成時的區(qū)別(一)：現在完成時表示的動作發(fā)生在說話之前某個沒有明確說出的過去時間，側重過去發(fā)生的動作對現在產生的影響或造成的結果,與現在有關；過去完成時的動作發(fā)生在“過去的過去”,它是一個相對的時態(tài),不能離開過去的時間而獨立存在?，F在完成時與過去完成時的區(qū)別(二)：現在完成時常用時間狀語：sofar,lately,recently,bytheendof,sincethen/1990,fortenyears,eversince,uptonow,inthepast/lastfewyears/days,already,yet.現在完成時與過去完成時的區(qū)別：過去完成時常用時間狀語：bythen,bythattime,already,yet,until,bytheendof,before2000,bythetime,nosooner...than/hardly...when...一就1.Wehavelearnedover800Englishwordsbytheendofthisterm.2.Wehadlearnedover800Englishwordsbytheendoflastterm.1.Wehavecollected1000stampssofar.2.Wehadcollected1000stampsbythen.1.SincewebegantousetheInternet,ourlives_______alot.A.change
