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
5、 built three years ago.这座桥是三年前修建的。2 .否定句：主语+ was/were 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。3 . 一般疑问句：Was/Were+主语+及物动词的过去分词+其他?e.g. Were these pictures drawn by your sister?这些图片是由你妹妹画的吗？肯定回答Yes,主语 + was / were.Yes, it was.否定回答No,主语 + was / were
6、+ not.No, it wasnt.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?【拓展】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. They put off the meeting because of the weather.The meeting was put off because of the weather.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”
7、的直接宾语变为主语，则在间接宾语前加to 或 fOFoe.g. My aunt gave me an e-dictionary yesterday.I was given an e-dictionary yesterday.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 e
8、nter 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 happened to Mr. Brown?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。主动结构：I found him lying on the floor.被动结构：He was found lying on the floor by me.IV. ExercisesI.根据各题后括号内的要求

11、he sentences in 4a and rewrite the sentences using the passive voice.2 .做题方法点拨示例：点拨：原句为一般过去时态，原句的谓语动词为sold,宾语为the fridge；改为被动语态时，应将the fridge作主语，谓语动词用was sold的形式。They sold the fridge at a low price. 一The fridge was sold at a low price.点拨：分析原句的句子结构可知，stole是谓语动词，my camera是句子的宾 语；改为被动语态句时，应将my camera作句
12、子主语，谓语动词用was stolen的 形式。Somebody stole my camera from my hotel room. 一My camera was stolen from my hotel room.学生们自主将其他三个句子变成被动语态。3 .最后，教师与同学们一起校对答案，并对学生们有疑问的地方进行解释，或做 出合理的分析点拨。Where were these photos taken?We were advised not to go out alone.The book was translated into different languages by differ
