The office was cleaned yesterday. Compare active and passive 动作的接受者the office成了句子的主语，就应当用被动语态。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（bear） －When were you born －I was born in 1989. 假如要特殊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. 公园旁边在建一些房子。 （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.
