九年级U1语法被动语态

Grammar英语有两种语态：主动语态和被动语态。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。1.被动语态基本结构：be+及物动词的过去分词（如果是不及物动词，其过去分词应带有相应的介词）2.一般现在时的被动语态为：am/is/are+过去分词

一般过去时的被动语态为：was/were+过去分词

3.与情态动词连用的被动语态：

can/should/must/will+be+过去分词4.被动语态中动作的发出者或执行者做介词by的宾语，放在句末，by表示“由，被”的意思。

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.English

isspokenallovertheworld.

全世界都在说英语。2.需要突出或强调动作的承受者。

e.g.Thisdictionaryisusedbymost

students.这本字典是大多数学生在用的。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.Theyputoffthemeetingbecauseoftheweather.→Themeetingwasputoffbecauseoftheweather.会议因天气的缘故被推迟了。三、主动语态变被动语态应注意的问题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.

Myauntgavemeane-dictionaryyesterday.

I

wasgivenane-dictionaryyesterday.

Ane-dictionarywasgiven

tomeyesterday.3.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.

Aheavymanwasseentoenterthehouse.4.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.WhathappenedtoMr.Brown?
