Why 指原因,在定语从句中作原因状语。先行词为reason 时,可用for which指代;当关系词在从句中作主语或宾语时,则用which或that 引导。如:
1. The reason why / for which / (that) he didn't attend the meeting was that he was ill.(作状语)
2. I don't believe the reason (that/which) he gave me. (作宾语)
Have you asked him the reason that may explain his success? (作主语)
