這題牽涉到非謂,AC不敢確定,我覺(jué)得都可以.因?yàn)閐are做主動(dòng)詞的時(shí)候,后加不定式可帶to也可不帶to.親愛(ài)的好人，你能給我講解一下這道題嗎？關(guān)于非謂語(yǔ)和dare的用法這兩點(diǎn)Seeing that his father was in a gray mood, the little boy主語(yǔ) sat 謂語(yǔ)quietly, not ____ tell him his failure in the exam. 首先要找到一個(gè)句子的主語(yǔ)和謂語(yǔ)。另外在看這個(gè)句子有沒(méi)有連詞，比如and ，but。該句沒(méi)有。Seeing that his father was in a gray mood, =because he saw that his father was in a grey mood,非謂語(yǔ)就是沒(méi)有主動(dòng)詞，該句的because he 都可以省略，而省略后，saw就要改成seeing。后面這半句，仍然我們找不到連詞，所以要用非謂，用daring to。我現(xiàn)在覺(jué)得應(yīng)該選這個(gè)而不是daring。做實(shí)義動(dòng)詞用。dare做情態(tài)動(dòng)詞的時(shí)候過(guò)去式形式dared。沒(méi)有daring的形式。常用于否定句，疑問(wèn)句。做實(shí)義動(dòng)詞的時(shí)候，也常用于否定句和疑問(wèn)句，后加不定式可帶to也可不帶to。 she didn't dare (to) say anything about it.
