/hu:m ||; hum/pronoun (
formal 正式) used instead of ‘who’ as the object of a verb or preposition (代替who, 用作动词或介词的宾语):
Whom did you meet there? 你在那儿碰见了谁?He asked me whom I had met. 他问我碰见了谁。To whom am I speaking? 请问尊姓大名? The use of whom instead of who is very formal. We usually express a sentence such as: He asked me with whom I had discussed it.’ as ‘He asked me who I had discussed it with.’ (Note the position of the preposition at the end.) 以whom代替who是很正式的用法。He asked me with whom I had discussed it通常都写成He asked me who I had discussed it with。(注意,介词放在句末。)
