dare作实义动词和dare作情态动词分别是什么意思？

都是“敢”的意思，只是用法不同，语气不同。情态动词所表达的感情色彩更强，实意动词更强调客观，当然，这只是细微的差别，主要还是用法不同

dare用作情态动词时，表示“敢于”这个意思，主要用于疑问句、否定句及条件从句。

【例如】

Dare you go home alone?

Tom dare not gosintosthe haunted house.

How dare you say such a thing to your father!

I won't allow you to swim across the river, even if you dare do it. The current is too swift.

但在现代英语中dare, need一样用作及物动词的时候更多一些，后面可以跟不定式，用于各种结构中。

【例如】

Does Tom dare to gosintosthe haunted house?

I have never dared to tell him about it.

She stopped at door, not daring to enter.

If you dare to say"No", I will beat you.

He didn't dare to do it because he was under inspection.

dare用作情态动词时，表示“敢于”这个意思，主要用于疑问句、否定句及条件从句。
