可以Depending on its sense,the verbdare sometimes behaves like an auxiliary verb (such as can or may ) and sometimes like a main verb (such aswant or try ).When used as an auxiliary verb,dare does not agree with its subject:
從意義上來說,動(dòng)詞dare 有時(shí)相當(dāng)于助動(dòng)詞（如 can能 或 may可能 ),有時(shí)相當(dāng)于實(shí)義動(dòng)詞 （如want想 或 try試著 ).當(dāng)用作助動(dòng)詞時(shí),dare 不和主語一致：
Let him say that if he dare.
如果他敢的話讓他說,
It also does not combine withdo in questions,negations,or certain other constructions:
它也在疑問句、否定句和其他某些結(jié)構(gòu)中,不需和do 連用：
Dare we tell her the truth?
我們敢告訴她實(shí)情嗎?
I dare not mention their names.
我不敢提他們的名字.
Finally,it does not taketo before the complement verb that follows it:
最后,在緊跟其后的輔助動(dòng)詞前不用帶上to ：
If you dare breathe a word about it I'll never speak to you again.
如果你敢說出去一個(gè)字,就再不和你說話.
When used as a main verb,dare does agree with its subject (
當(dāng)用作實(shí)義動(dòng)詞時(shí),dare 一定要和主語一致(
If he dares to show up at her house I'll be surprised),
如果他敢出現(xiàn)在她的房子里,我會(huì)感到吃驚),
and it does combine withdo (
它必須和do 連用(
Did anyone dare to admit it?).
有人敢于承認(rèn)嗎?).
It may optionally taketo before the verb following it:
有可能選擇性地在緊跟其后的動(dòng)詞前加to ：
No one dares (or dares to ) speak freely about the political situation.
沒有人敢（或 dares to ) 自由地談?wù)撜涡问?.
The auxiliary forms are used primarily in present tense questions,negations,imperatives,and conditional clauses.These forms differ subtly in meaning from the main verb formsin that they emphasize the attitude or involvement of the speakerwhile the main verb forms present a more objective situation.ThusHow dare she take the exam without ever once coming to class?expresses indignation at the student's action,whereasHow did she dare to take the exam without ever once coming to class?is a genuine request for information.Whendare is used as a transitive verb meaning “challenge,” only main verb forms are possible andto is required:
助動(dòng)詞形式主要用于一般現(xiàn)在時(shí)疑問句、否定句、祈使句和條件從句中.這些形式和實(shí)義動(dòng)詞形式的意思有細(xì)微的差別,即他們強(qiáng)調(diào)說話者的態(tài)度和參與,而實(shí)義動(dòng)詞形式給出一個(gè)較客觀的形勢.因此她怎么敢從未上過課就參加考試呢?表示對(duì)該學(xué)生行為的憤怒,然而她從未上過課怎么敢參加考試呢?是一真實(shí)的信息需求,當(dāng)dare 用作及物動(dòng)詞意指“挑戰(zhàn)”時(shí),只能是實(shí)義動(dòng)詞形式而且要接to ：
Anyone who dares (not dare ) him to attempt (not just attempt ) it will be sorry.
任何敢于（不是 dare ) （不僅僅是 attempt ) 挑釁他去做的人會(huì)遺憾的
