1） dare用作實(shí)義動詞,此時(shí)其后的動詞不定式可帶to也可不帶to,且dare有人稱和數(shù)以及時(shí)態(tài)的變化.例如：
I dare to jump down from the top of the wall. 我敢從那墻頭上跳下來.
She doesn\'t dare (to) meet her teacher\'s eyes. 她不敢與老師對視.
2） dare用作情態(tài)動詞,后跟動詞原形,主要用于疑問句、否定句和條件句中.例如：
How dare she do things like that to me? 她怎么敢對我做那種事?
-Dare you catch the mouse? 你敢去抓那只老鼠嗎?
-I daren\'t do that. 我不敢抓.
If you dare say that to our teacher, I would vote for you. 如果你敢向我們的老師說那件事,我就投你一票.拜托，好好回答問題，不要從哪里截了一段了事
