dare的3種用法

　　dare可以作實(shí)義動(dòng)詞,也可以作情態(tài)動(dòng)詞.

　　(1)dare作情態(tài)動(dòng)詞時(shí)后面接動(dòng)詞原形(不帶to的動(dòng)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(dòng)詞時(shí)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(gè)例外—I dare say,但那是一個(gè)固定短語,意思是“我相信, 可能, 我想是這樣”).

　　(2)實(shí)義動(dòng)詞dare后面接動(dòng)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.)

　　(3)在否定句或疑問句中,現(xiàn)代英語口語常用實(shí)義動(dòng)詞的dare,但省略后面的to,直接接動(dòng)詞原形.如：

　　I don't dare say that.

　　Do you dare go with me?
