一般過去時被動語態(tài)表達過去經(jīng)常性、習(xí)慣性被動動作或過去某一時刻發(fā)生被動性動作。其構(gòu)造為：主語(動作承受者)+was/were+過去分詞(+by+動作發(fā)出者)組成,其否認(rèn)形式was/were后加not。如：IwastaughtbyMissZhaolastyear.

Thoseletterswerewrittenbyafamouswriter.

第14頁【注意】被動語態(tài)還可用于：強調(diào)動作承受者，而不強調(diào)動作執(zhí)行者。如：ThewindowwasbrokenbyMike.

Thisbookwaswrittenbyhim.二、積極語態(tài)變被動語態(tài)辦法(1)把積極語態(tài)賓語變?yōu)楸粍诱Z態(tài)主語。(2)把謂語變成被動構(gòu)造(be＋過去分詞)(根據(jù)被動語態(tài)句子里主語人稱和數(shù)，以及本來積極語態(tài)句子中動詞時態(tài)來決定be形式)。第15頁語法復(fù)習(xí)(3)把積極語態(tài)中主語放在介詞by之后作賓語,將主格改為賓格。

Allthepeoplelaughedat
