請告訴我 「我不知道」 的英語！

・I had no idea that.
・I had no knowledge about that.

「我不知道」（除了 I didn't know that. 之外）英語可以用 I had no idea that. 或 I had no knowledge about that. 來表達。

To be honest, I had no idea that the sport had changed so much in the last 10 years.
（說實話，我不知道這項運動在過去十年變化如此之大。）

Originally I was just a company employee and had no knowledge about space and physics.
（我原本只是個公司職員，對宇宙和物理一無所知。）

以上供你參考，希望有幫助到你。
