作為情態(tài)動(dòng)詞表示“膽敢”，dare通常只用于否定陳述句和疑問句。例如：

I dare not go there.

How dare he say such rude things about me?

dare作為情態(tài)助動(dòng)詞沒有過去式形式，其否定式為daren't，既可指現(xiàn)在時(shí)間，也可指過去時(shí)間。例如：

Tom wanted to come, but he daren't.

dare還可用主動(dòng)詞，隨后的不定式可帶to,也可不帶to.例如：

He does not dare (to) answer.

Does she dare (to) go there alone?
