dare可以作實義動詞,也可以作情態(tài)動詞.
(1)實義動詞dare后面接動詞不定式to do.如:
I dare to swim across the river
I don't dare to say that.
Do you dare to go with me?(肯定回答:Yes, I do. 否定回答:No, I don't.)
(2)dare作情態(tài)動詞時后面接動詞原形(不帶to的動詞不定式).如:
I daren't say that.
Dare you go with me?(肯定回答:Yes, I dare. 否定回答:No, I dare not.)
How dare you say that?
If he dare break the rule , he will be punished .
注意:dare作情態(tài)動詞時主要用于疑問句,否定句和條件從句中,不用于肯定句(只有一個例外—I dare say,但那是一個固定短語,意思是“我相信, 可能, 我想是這樣”).
(3)在否定句或疑問句中,現(xiàn)代英語口語常用實義動詞的dare,但省略后面的to,直接接動詞原形.如:
I don't dare say that.
Do you dare go with me?
