過去完成時的被動語態(tài)過去完成時的被動語態(tài)由“had been+及物動詞的過去分詞”構(gòu)成，表示在過去某一時刻或某一動作之前“被”，句中常用by，before，until，when等詞引導(dǎo)時間狀語。
過去完成時的被動語態(tài)有以下三種形式：(1)肯定結(jié)構(gòu)：主語+ had been done +其他成分(2)否定結(jié)構(gòu)：主語+ had not been done +其他成分(3)疑問句結(jié)構(gòu)： had +主語+ been done +其他成分;疑問詞+ had +主語+ been done +其他成分
2.過去完成時的被動語態(tài)的用法(1)表示在過去某-時間或動作之前已經(jīng)完成的被動動作，常與by，before等 引導(dǎo)的時間狀語連用。By the time we got there, all the tickets had been sold out.我們到達那里時，所有的票都賣完了。
(2)表示從過去某一時間開始，延續(xù)到過去另一時間的被動動作，常與for，since引導(dǎo)的時間狀語連用。It was reported that the new toothpaste had been advertised for several weeks.據(jù)報道，這種新牙膏已經(jīng)做了好幾個星期的廣告了。
(3)用在賓語從句中， 常放在said, told， thought， wondered等動詞過去式的后面，表示在這些動作之前已經(jīng)發(fā)生的被動動作。He told us that the experiment had been completed.他告訴我們實驗已經(jīng)完成了。
