情态动词复习
情态动词(Modal verbs)的含义:
情态动词是一种表示语气的单词,用来丰富说话人对这一动作或状态的看法和情感。不能单独做谓语,总是用在动词原形之前。
情态动词有can (could), may (might), must, have to, shall (should), will (would), need (needed),等
情态动词
must
have to
can
could
may
might
shall
should
will
would
情态动词复习
口诀:
情态动词要记牢,动词原型来跟梢,
不分人称和数量, 不同情感要看好。
Can表能力和许可,也许、可能may来,
表一定必须must,should应该来报道。
否定变化也不难,情态后把not添。
疑问变化往前跑,Must回答要记好。
特殊用法:must…
Must I do my homework now (做否定回答)
________________________
No, you needn’t.
