多么美麗的一天啊，大家好，歡迎回來，收聽并學習《Faith口語課堂-天天學》，我是Faith老師。在這個網上英語口語課堂里，每天教大家一點口語用法，日積月累，你的口語進步可真的會很大哦！ 
首先來認識一下這個詞：stumble, vi.絆腳，跌跌撞撞地走，(說話、演奏等)出錯

She stumbled on a stone. 她被一塊石頭絆了一腳。

He chugged the rest of his beer and stumbled over to the two girls. 他把杯中的啤酒一飲而盡，然后跌跌撞撞地向那兩個女孩走去。

He stumbled over every sentence. 他講每句話都結結巴巴。

I'm stumbling at this step and can't make a move. 我對這一步驟躊躇不決，沒能往前邁。 

Have/has absolutely no idea…“完全沒概念，完全沒頭續”，后面接一個句子（可以以特殊疑問詞引導：how, what, when, why, where, who, how much, how many…，也可以以that引導，等等）

I had absolutely no idea what to do so I just replied in English, "hey, your Japanese is pretty good". 我完全傻了眼，所以，只好用英語回答說：“嗨，你日語講得真好。”

I have absolutely no idea where I’ve met him. 我完全傻了眼，不記得在哪兒見過他。

I just think you should be on your guard. You have absolutely no idea who this Jed guy is. 我只是覺得你最好提高警覺。畢竟你完全不知道這個叫杰德的家伙究竟是個什么樣的人。

I was embarrassed, because I had absolutely no idea. 我因為沒有主意而不知如何是好。

I had absolutely no idea what she referred to. 我根本不知道她指的是什么。

同時，Have/has absolutely no idea…后面還可以接一個由“of”引導的短語： I had absolutely no idea of his age. 我完全不知道他多大歲數了。 I have absolutely no idea how you like my class, will you tell me?
