初中英语情态动词的用法归纳定义情态动词表示说话人对某一动作或状态的态度,表示“可能”,“可以”,“需要”,“必须”,“应当”等意思。

情态动词的种类:初中英语情态动词的用法归纳,情态动词用法有哪些情态动词的常见用法:1.can和could的用法(1)can/could 表示“能力;许可;可能性”等。

could 为 can 的过去式。

如:Can I use your book?我可以用你的书吗?(2)can 用在疑问句中,表示征求意见、请求许可,答语仍用can; could 用在疑问句中,比can 更委婉、客气,是一种礼貌的说法,并不表示过去时态,答语用can,而不能用could。

Eg: -Could you tell me the way to the park?你能告诉我去公园的路吗?-Sorry. I can't. I'm new here。

不好意思,我不知道。

我是新来的。

[注意]①can 和could 只能用于现在时和过去时两种时态。

②另外, can't 可表示否定推测。

2.may和might的用法may/might 意为“可以”,表示同意、许可或请求对方许可,也可表示祝愿。

might 是may 的过去式,有两种用法:一种表示过去式;一种表示虚拟语气,使语气更加委婉、客气,或表示可能性更小。

以may开头的一般疑问句,其否定回答用mustn't。

Eg: MayI use your book? 我可以用你用的书吗?He might be alive. 他可能还活着。

【注意】can和may都可以用来表示请求或允许,但may比can更正式,更客气。
