6、l in 1876.,invented,was invented by,Grammar,一般现在时的被动语态中讲到的“被动语态的用法”和“如何将主动语态(含“主+谓+宾”句型的句子)变为被动语态”同样适用于一般过去时的被动语态，不同的只是这两种时态的被动语态的“构成”，所以这里我们重点讲解一般过去时的被动语态的构成(was / were +及物动词的过去分词)及在各种句式中的运用。,1. 肯定句： 主语+was / were+及物动词的过去分词+其他.,e.g. The bridge was built three years ago. 这座桥是三年前修建的。,2. 否定句：主语+ was/w
7、ere not+及物动词的过 去分词+其他.,e.g. Women were not allowed to take part in the games at first. 开始妇女不允许参加奥运会。,e.g. Was this picture drawn by your sister? 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?,4. 特殊疑问句：疑问词（不作主语） + was / were +主语 + 及物动词的过去分词(+ by短语) + 其他? e.g. When was the bridge built?,1. 有些短语动词相当
8、于及物动词，变为被动结构时介词或副词不能去掉。,e.g. They put off the meeting because of the weather. The meeting was put off because of the weather.,【拓展】,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. My aunt gave me an e-dictionary yesterday. I was given an e-dictionary yesterd
9、ay. An e-dictionary was given to me 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. I saw a heavy man enter the house. A heavy man was seen to enter the house.,4. 系动词、不及物动词或某些短语动词（happen, take place, come true, fall asleep）没有被动语态。,e.g. What
10、 happened to Mr. Brown? 布朗先生发生了什么事？,5. 含复合宾语(宾语 + 宾语补足语)的主动结 构变被动结构时，通常把主动结构中的宾 语改为被动结构中的主语，而宾语补足语 保留在谓语动词后面成为主语补足语。 如： 主动结构：I found him lying on the floor. 被动结构：He was found lying on the floor by me.,I. 根据各题后括号内的要求完成下列各题，每 空一词（含缩略形式）。1.
