外國(guó)人日常短語(yǔ) 第277期:not know the first thing about
釋義：
not know the first thing about 對(duì)……一無所知
這是強(qiáng)調(diào)“對(duì)某事一無所知”的表達(dá)。about 后面接上要表達(dá)的事實(shí)就可以了。相似的句型有 not know the half of，not know a thing about 等。只不過 know a thing or two about 表示“對(duì)某事非常了解”。
例句：
I don't know the first thing about how to use it.
我完全不知道這個(gè)東西的使用方法。
You don't know the half of it.
你根本就不知道事態(tài)有多么嚴(yán)重。
I know a thing or two about playing computer games.
我非常了解電腦游戲。
對(duì)話：
A: Mary needs help with her computer.
瑪麗的電腦壞了，需要幫助。
B: I don't know the first thing about computers.
我對(duì)電腦一無所知。
