Where does he come from?中的 when是不是宾语?

介词短语＂from + 地点名词＂作句子的状语,这里就是对这个＂地点名词＂进行提问 补充：问地点就是用wherre来提问
eg:１． I go to school by bus every day.(对school 提问）
２．He has been there for three years.(对there提问）
Where has he been for three years?追问：where 可以作宾语?回答：副词ad.
1.(用作疑问副词)在哪里;往哪里;从哪里;在哪一点上

2.(用作关系副词,引导关系从句)在那里;往那里
