dare不仅可以做情态动词,也是一个动词,这是它与must之类的最大区别。
在做情态动词是可以不加to,做及物动词和系动词时要加to。这完全取决于说话者的心情,与要表达的意思没有什么关系。
dare:
n. 挑战,挑动
v. 敢,胆敢
词形变化:
名词:darer 动词过去式:dared 过去分词:dared 现在分词:daring 第三人称单数:dares
例句与用法:
1.情态动词用法:
How dare you say so?
你怎敢这样说?
2.动词用法:(这个例句中,dare同样是动词,但是和LZ给出的例句中的dare意思有差异)
He dared me to jump over the river.
他激我跳过河。
好了,以下是回答的补充:
dare
Function:verb 而作为动词仍有两种用法:
Inflected Form:dared ; daring ; dares or (auxiliary) dare
1.作为系动词:
verbal auxiliary : to be sufficiently courageous to *no one dared say a word* *she dare not let herself love G. B. Shaw*
intransitive senses : to have sufficient courage *try it if you dare*
2.作为及物动词:
transitive senses
(1) a : to challenge to perform an action especially as a proof of courage *dared him to jump*
b : to confront boldly : DEFY *dared the anger of his family*
(2)to have the courage to contend against, venture, or try *the actress dared a new interpretation of this classic role*
以上补充部分引自Webster,非常权威。(中文部分是我做的一点小小的说明……)
