dare 该如何使用?

　　关于dare这个词的词性一直是一个疑惑，普遍认为它可以作为情态动词。但是牛津词典上似乎也没有说明它可以做情态动词。但无论词性如何，用法是一定的。

　　你说的那两句的用法是一样的，dare在否定句中后面加带to或者不带to的动词不定式。第一句是不带to的动词不定式，第二句是带to的动词不定式。两种用法无区别，都可以。

　　参见《牛津用于用法指南 Practical English Usage》第151条 第2项 第1款：

　　当然也可以看到还有其他用法，比如常用的搭配 dare say，表示：认为很可能，以及donot you dare,how dare you等固定搭配，记住就好。特别地，有一个dare sb to do sth.，表示鼓动对方做吓人的事情，类似于中文的“谅你也不敢”。还有对于不敢可以用“daren't”加不带to的动词不定式，其三单形式依然是“daren't”。这些固定用法很少，其他情况下现代英语一般不用dare。

　　所以不用太过纠结dare这个词的词性，知道这几个常见固定的用法就行。希望对你有帮助
