题目内容：

I don't know which channel in CCTV my favourite program is
具体点,
可是答案是I don't know which channel in CCTV my favourite program is on

优质解答

对的
含义：我不知道中央台中我最喜欢那个频道.
which channel in CCTV my favourite program is 是宾语从句,in CCTV 是状语,也可以放在后面；主语是my favourite program
换个语序会更容易理解一些：
my favourite program is which channel in CCTV
当然,I don't know 就是主句了.
