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

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

inthefactoryfortwentyyears.
