语法题中的非语法问题 《OG》第139题:The extraordinary diary of William Lyon Mackenzie King, prime minister of Canada for over twenty years, revealed that this most bland and circumspect of men was a mystic guided in both public and private life by omens, messages received at séances, and signs from heaven. 我想知道划线部分中的was的主语是什么?如果是this most bland and circumspect of men那么其中的of 怎么那么别扭, 我没有学到过,望高人指点一二。(I do not believe that ETS can make such a mistake! It is impossible)
