1） dare用作實(shí)義動(dòng)詞,此時(shí)其后的動(dòng)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(duì)視.
2） dare用作情態(tài)動(dòng)詞,后跟動(dòng)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(duì)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.
