求翻译：在还未开始听演讲之前,我们都以为这只是一个和以前差不多的枯燥的英语知识讲座，可是当纪教授刚刚走上台张开口向大家问好的那一刻，就让我们有了与之前截然不同的看法。是什么意思？

Before the speech has not yet begun to listen, we all thought it was just a boring and almost before the English lectures, but when Professor Ji took the stage to open your mouth just to say hello at the moment, let us have very different with the previous views.
