情态动词的被动语态

Question

如题所述

Answer 1

情态动词中，主语和谓语动词之间有关系：主动关系或被动关系。
当主语与谓语为被动
关系时，体现主语为动作的承受者时要用被动语态（the
Passive
Voice）。在被动结构为：主语+be
过去分词
+by+动作执行者。
常见的情态动词为：can
(could),
may
(might),
must,
have
to,
shall
(should）,
will
(would),
dare
(dared),
need
(needed),
ought
to等。此外，情态动词无人称和数的变化，所以不考虑主谓一致。但shall
(should）,
will
(would),
dare
(dared),
need
(needed)体现了原形与过去式的关系。
