I don't know ____.
A which floor does he live on
B which floor he lives
C on which floor he lives
(请务必说明原因)
A which floor does he live on
B which floor he lives
C on which floor he lives
(请务必说明原因)
c.这是一个宾语从句，还原后为I don't know he lives on which floor.
a中的does应该去掉，b中少了介词on,c中将从句谓语部分的介词以后的部分倒装，这在从句为疑问句的宾语从句中是允许的。但有些词组是不能分开的，比如:look after。不能说：I don't know after whom he is looking .
只能说:I don't know whom he is looking after.
我选B ，直觉。。。呵呵，念着顺
