普通過去時被動語態(tài)表示過去經(jīng)常性、習慣性被動動作或過去某一時刻發(fā)生被動性動作。其結構為：主語(動作承受者)+was/were+過去分詞(+by+動作發(fā)出者)組成,其否定形式was/were后加not。如：IwastaughtbyMissZhaolastyear.

Thoseletterswerewrittenbyafamouswriter.

14/25【注意】被動語態(tài)還可用于：強調動作承受者，而不強調動作執(zhí)行者。如：ThewindowwasbrokenbyMike.

Thisbookwaswrittenbyhim.二、主動語態(tài)變被動語態(tài)方法(1)把主動語態(tài)賓語變?yōu)楸粍诱Z態(tài)主語。(2)把謂語變成被動結構(be＋過去分詞)(依據(jù)被動語態(tài)句子里主語人稱和數(shù)，以及原來主動語態(tài)句子中動詞時態(tài)來決定be形式)。15/25語法復習(3)把主動語態(tài)中主語放在介詞by之后作賓語,將主格改為賓格。

waslaughedatbyallthepeople.(主語：動作發(fā)出者)（賓語：動作承受者）.（主語：動作發(fā)出者）（賓語：動作承受者）16/25一、寫出以下短語英文表示。1.錯誤地
