情态动词后边要求动词原型，因而，be永远为be，
结构：情态动词＋be＋过去分词
注：原来带to的情态动词变成被动语态后”to“仍要保留
e.g.: We can repair this watch in two days.
This watch can be repaired in two days.
They should do it at once.
It should be done at once.
考点一
情态动词的被动语态（九年级Unit3）
无宾语的动词不可以变为被动语态
如：主语 + 系动词 + 表语
主语 + 不及物动词 + 介词 + 宾语
中考考察典型动词 take place, happen, change 等
e.g.: He _______ (feel) better.
考点二
feels
被动语态妙 无宾不能要 主宾打颠倒 格变不能少
介宾可不要 助be往出跳 去把动原叫 时语兼顾到
人数把主照 若是有助动 助be则不照 动原过分现
变be后边站 这是基本变 考点往下看 双宾均可变
人变顺序变 物变to/for现 复宾补不变 对于省to案
还原to来办 含情语态变 不必be来换 情后be +p.p站
主动语态变被动语态的方法口诀：
