got200picturesfromthespaceship.2.Ihadbeenatthebusstopfor20minuteswhenabusfinallycame.3.Hesaidhehadworkedinthatfactorysince1949.4.Thetrainhadn'tleft

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

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