主动语态表示主语是动作的执行者，而被动语态则表示主语是动作的承受者。

如：一、一般过去时被动语态一般过去时被动语态的结构为“主语+was/were+及物动词的过去分词

(+by+动作的执行者).”。如：

Trees

lastspring.去年春天种了树。wereplanted

二、被动语态的用法：1.不知道谁是动作的执行者，或没有必要指出谁是动作的执行者。e.g.

allovertheworld.全世界都在说英语。2.需要突出或强调动作的承受者。e.g.

Thisdictionary

moststudents.这本字典是大多数学生在用的。Englishisspokenisusedby三、主动语态变被动语态应注意的问题

1.有些短语动词相当于及物动词，变为被动句时介词或副词不能去掉。e.g.

Theyputoffthemeetingbecauseofthe

weather.→Themeeting

becauseofthe

weather.会议因天气的缘故被推迟了。wasputoff

2.含有双宾语的主动句变为被动句时，通常把指“人”的间接宾语变为主语，指“物”的直接宾语保留不变；如果把指“物”的直接宾语变为主语，则在间接宾语前加to或for。e.g.

Myauntgavemea

dictionary

yesterday.

I

a

dictionaryyesterday.

A

dictionary

yesterday.wasgiven

wasgiventome3.主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to的动词不定式，变为被动语态时应加上不定式符号to。e.g.

Isawaheavymanenterthehouse.

Aheavyman

thehouse.

wasseentoenter4.系动词、不及物动词或某些短语动词（happen,takeplace,cometrue,fallasleep…）没有被动语态。e.g.

toMr.Brown?布朗先生发生了什么事？Whathappened4aPracticeRewritethesentencesusingthepassivevoice.原句为一般过去时态，谓语动词为sold，改为被动语态时，应将thefridge作主语，谓语动词用wassold的形式。1.Theysoldthefridgeatalowprice._____________________________Thefridgewassoldatalowprice.

stole是谓语动词，mycamera是句子的宾语；改为被动语态句时，应将mycamera作句子主语，谓语动词用wasstolen的形式。2.Somebodystolemycamerafrommyhotelroom.__________________________________________________________________Mycamerawasstolen(bysomebody)
