主语+was/were+及物动词的过去分词+其他.e.g.Paperwasinvented

byChinesepeopletwothousandyearsago.纸是中国人在二千多年前发明的。

2.

否定句：

主语+was/werenot+及物动词的过

去分词+其他.e.g.

Womenwerenotallowedtotakepartinthegamesatfirst.

开始妇女不允许参加奥运会。e.g.Wasthispicturedrawnbyyoursister?这幅画是你妹妹画的吗？

3.一般疑问句：

Was/Were+主语+及物动词的过去分

词+其他?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.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.Thisdictionaryisusedbymoststudents.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

tome

yesterday.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.e.g.WhathappenedtoMr.Brown?

布朗先生发生了什么事？将下列句子变为被动语态。1.Hechosesixstorybookstheotherday. Sixstorybooks____________byhimthe otherday.2.UncleLeegaveJackalargecakeforhe paintedthewallwonderfully.
