Which floor does he live on?live后面为什么要加介词on Where does he li which floor does he live on 的同义句 where does he live 为什么不是 where does he lives? which floor does each of them live on? where does he live还是where does he live in where does he live?翻译 Where does he live?为什么用does 不用is Which floor does your uncle_______?里面是填live,live on,lives还是l where does he live?不加in 为什么he lives in Japan.就要加in? where does he live(变同义句） which piace does he ( ) ( ) Which floor does your best friend live on?She lives on the s Where does he/she live?这里为什么要放does 不放is啊
