(这个问题可以轻易解决。) The work must be finished today. (这项工作今天必须完成。) These flowers should be watered every day. (这些花应该每天浇水。) 2. 否定句 主语 + 情态动词 + not + be + 过去分词 This door cannot be opened. (这扇门打不开。) The machine must not be used by children. (儿童严禁使用这台机器。) The rules should not be broken. (规则不应该被破坏。) 3. 一般疑问句 情态动词 + 主语 + be + 过去分词 (+ ...)

(他可能会被要求发言。) might might do might be done It might be delayed by the rain. (它可能会因下雨而延误。) must must do must be done The law must be obeyed. (法律必须被遵守。) should should do should be done Children should be taught to be honest. (应该教孩子们诚实。) ought to ought to do ought to be done The environment ought to be protected. (环境应该得到保护。) have to have to do have to be done The windows have to be cleaned. (窗户不得不擦了。) 四、 注意事项 1. 保持"be"动词的原形 在情态动词被动语态中，be 永远保持原形，不能随主语的人称和数发生变化。 (正确) The book must be returned. (书必须被归还。) (正确) The books must be returned. (书必须被归还。) (错误) ~~The book must is returned.~~ (错误) ~~The books must are returned.~~ 2. 及物动词才有被动语态 只有及物动词（后面可以接宾语的动词）才能构成被动语态。不及物动词（如 happen, appear, die 等）没有被动语态。 (正确) The accident was seen by many people. (事故被许多人看到了。) (错误) ~~The accident was happened yesterday.~~ ( happen是不及物动词) 3. 短语动词的被动语态 许多"动词+介词/副词"构成的短语动词相当于一个及物动词，也可以用于被动语态，介词或副词不能省略。 主动： We should take good care of the children.
