不!它指的是人類歷史上特定時期之前的時期。因為gluten直到最近才成為人們會感興趣的眾所周知且重要的東西。在此之前,這根本不是問題。示例: For the previous entirety of my work life, I never considered changing careers until now. = Until now, I never considered changing careers. (我從沒想過換工作。) 例子: For the previous entirety of human history, we weren't nearly as concerned with the environment as we are now. (在整個人類歷史的前一個時期,我們很少像現在這樣關注環境。)
