→现在完成时 动词的被动形式：has/have been done 例句：The house has been built. →过去完成时 动词的被动形式：had been done 例句：They said that their work had been finished. 含有情态动词的被动语态:情态动词+be+ done Your homework must be handed in today. 其它几种特殊句型： It is said that …….. It is well known that ……. It is reported that…… 例： ①History is made by the people. (一般现在时) ②The cars were made in Tianjin in 1995. (一般过去时) ③The tree will be cut down next year.(一般将来时) ④The room must be kept clean.（含有情态动词的被动语态） ⑤The door is being opened.（现在进行时） ⑥The film has been seen by me.（现在完成时） 注：☆不同时态的被动语态的差异主要体现在助动词be的变化上,同时助动词be还要在人称和数上与主语保持一致。 ③应用情况 行为的执行者不明确或不必说出来。 Eg: A stranger was killed last night. 用于强调动作的承受者而不是执行者。 Eg: The story is told everywhere in the city.
