将被动语态改成一般疑问句，主要需要调整的是谓语动词的位置，将be动词提前到主语之前。下面是具体的步骤：

一般现在时

被动语态结构：`am/is/are + 过去分词`

一般疑问句结构：`Is/Are + 主语 + 过去分词`

例句：`Most paper work is now done by computer.` 改为 `Is most paper work done by computer now？`

一般过去时

被动语态结构：`was/were + 过去分词`

一般疑问句结构：`Was/Were + 主语 + 过去分词`

例句：`His grandpa is gone to see by him.` 改为 `Was his grandpa gone to see by him？`

一般将来时

被动语态结构：`will/shall + be + 过去分词`

一般疑问句结构：`Will/Shall + 主语 + be + 过去分词`

例句：`More trees will be planed in and aroud our village.` 改为 `Will more trees be planed in and aroud our village？`

现在进行时

被动语态结构：`am/is/are + being + 过去分词`

一般疑问句结构：`Is/Are + 主语 + being + 过去分词`

例句：`The accident is now being looked into.` 改为 `Is the accident now being looked into？`

过去进行时

被动语态结构：`was/were + being + 过去分词`

一般疑问句结构：`Was/Were + 主语 + being + 过去分词`

例句：`The hall was being built last year.` 改为 `Was the hall being built last year？`

现在完成时

被动语态结构：`have/has + been + 过去分词`

一般疑问句结构：`Have/Has + 主语 + been + 过去分词`

例句：`The experiment has been done successfully.` 改为 `Has the experiment been done successfully？`

含有情态动词的被动语态

一般疑问句结构：`情态动词 + 主语 + be + 过去分词`

例句：`The work must be finished before ten o'clock.` 改为 `Must the work be finished before ten o'clock？`

通过以上步骤，你可以将被动语态轻松转换为一般疑问句。总结起来就是将be动词提前到主语之前，并根据时态进行相应的调整。希望这些信息对你有所帮助!
