關(guān)系代詞who與whom 的用法區(qū)別 兩者均只用于人,從理論上說,who 為主格,whom為賓格.如：Where’s the girl who sells the tickets?賣票的女孩在哪里?The author whom you criticized in your view has written a letter in reply.你在評論中批評的那個作者已寫了一封回信.但實際上,除非在正式文體中,賓格關(guān)系代詞 whom 往往省略不用,或用who或that代之.如：The man (that,who,whom) you met just now is called Jim.你剛遇見的那個人叫吉姆.不過,在以下幾種情況值得注意.如：(1) 直接跟在介詞后面作賓語時,只能用 whom,而且不能省略.如：She brought with her three friends,none of whom I had ever met before.她帶了brought with her three friends,none of whom I had ever met before.3個朋友來,我以前都沒見過.(2) 引導(dǎo)非限制性定語從句且作賓語時,who 和 whom均可用,但以用 whom 為佳,此時也不能省略.如：This is Jack,who [whom] you haven’t met before.這是杰克,你以前沒見過
從形式上來看,who(ever)是人稱代詞的主格形式,一般在句子中作主語；
whom(ever)是人稱代詞的賓格形式,故一般作賓語.一般說來,whomever不能做句子的主語.
