摘要： 被动语态的构成 (1)请大家看图 The office is cleaned every day. The office was cleaned yesterday. Compare active and passive: 动作的接受者the office成了句子的主语.就应该用被动语态.从上面的例句我们可以总结: 一般现在时的被动语态为:主+am / is / are (not)+过去分词 一般过去时的被动语态为:主+was / were+过去分词 如:Butter is made from milk. This house was built 100 years ago. 以前我们学过的was / were born生于.就是一个被动语态 born是个过去分词 -When were you born? -I was born in 1989. 如果要特别强调动作或行为的执行者.句子后面需接by~.译为“被(由)- 如:We were woken up by a loud noise. 我们被嘈杂的声音吵醒. (2)请看图: 从上面例子.我们可以看出现在进行时被动语态的构成为 主语+is / am / are +being +过去分词 再如:My car is being repaired now Some new houses are being built near the park. 公园附近在建一些房子. (3)请看图 BEFORE NOW 从上面例子.我们可以看出现在完成时被动语态的构成为: 主语+have / has +been+过去分词 如: My key has been stolen. My keys have been stolen. I am not going to the party, I haven’t been invited. 含有情态动词的被动语态 情态动词+be+过去分词 A note had better be left to him. Teenagers should be allowed to wear their own clothes. 这里我们列举了几个主要时态.那么其它时态呢? 一般将来时 主语+will+be+过去分词 过去将来时 主语+would / should + be +过去分词 过去进行时 主语+was / were +being +过去分词 过去完成时 主语+had+been+过去分词 被动语态的时态是由be的时态决定的.be是什么时态.全句就是什么时态.be动词后面的过去分词不变. 归纳: 肯定句:主语+be+过去分词+(by~) 否定句:主语+be not+过去分词+ 一般疑问句:Be +主语+过去分词+? 特殊疑问句:疑问词+be+主语+过去分词+?
