从形式上来看，who(ever)是人称代词的主格形式，一般在句子中作主语； whom(ever)是人称代词的宾格形式，故一般作宾语。一般说来，whomever不能做句子的主语。 偶在书上曾翻到一小规律： whoever=人称宾格+人称主格 whomever= 人称宾格+人称宾格 验证一下： 1. Give it to _____ asks for it first. Give it to him. He asks for it first. Give it to whoever asks for it first. (whoever= him+ he) 2. We will hire_______ is most qualified. We will hire her. She is most qualified. We will hire whoever is most qualified. (whoever= her+ she) 3. We will hire_____ you recommend. We will hire them. You recommend them. Therefore, We will hire whomever you recommend. ( whomever= them + them) 本文来源：https://www.wddqw.com/doc/c503cf81240c844769eaeebc.html
