普通过去时被动语态表示过去经常性、习惯性被动动作或过去某一时刻发生被动性动作。其结构为：主语(动作承受者)+was/were+过去分词(+by+动作发出者)组成,其否定形式was/were后加not。如：IwastaughtbyMissZhaolastyear.

Thoseletterswerewrittenbyafamouswriter.

14/25【注意】被动语态还可用于：强调动作承受者，而不强调动作执行者。如：ThewindowwasbrokenbyMike.

Thisbookwaswrittenbyhim.二、主动语态变被动语态方法(1)把主动语态宾语变为被动语态主语。(2)把谓语变成被动结构(be＋过去分词)(依据被动语态句子里主语人称和数，以及原来主动语态句子中动词时态来决定be形式)。15/25语法复习(3)把主动语态中主语放在介词by之后作宾语,将主格改为宾格。

Allthepeoplelaughedat

him.

He

waslaughedatbyallthepeople.(主语：动作发出者)（宾语：动作承受者）.（主语：动作发出者）（宾语：动作承受者）16/25一、写出以下短语英文表示。1.错误地
