定语从句of which,of whom,whose的用法
—How did you get in touch with the travel agent,Robin?
—Oh,that’s easy.I surfed the Internet and then called one ________ the telephone number is provided.
这里填of which,为什么不用of whom?指人不是要用whom吗?
答
of which,先行词是事、物；你说的题的先行词是one,即the travel agent（旅行社）,是物.
of whom,先行词是人
whose先行词和定语从句中的名词有所属关系,
