5)The windows in our classroom are cleaned once a week. BBAAA All the books were taken away.所有的书都被拿走了。动作的执行者是泛指或者不言自明时。被动语态的基本用法The toy is designed for children.在不知道动作的执行者是谁时。这款玩具是为孩子们设计的。需要强调动作的承受者时。My bike was repaired.我的自行车修好了。The problem was talked about just now.出于委婉或礼貌而避谈动作的执行者时。这个问题刚才被讨论过。Mr Wu is liked by all of his students.所有的学生都喜欢吴老师。在被动语态的句子中, 如果我们需要指出动作的执行者, 可以由by引出。有些动词常用于被动语态。如:
