B.who在定語從句中可以作主語或賓語;而在句子中mention是及物動詞,所以mention后可以直接加賓語,即選who.
太荒唐了,樓上的即使是從句卻狀語,who又怎么能夠作狀語?
he introduced me to a friend from America------he had often mentioned.
he introduced me to a friend from America------he had often mentioned.
a about whom b who c which d about which 為什么選b,who在從句中有不是作主語,
a about whom b who c which d about which 為什么選b,who在從句中有不是作主語,
