in the tomorrow afternoon对吗?

不对，可根据需要改说：
in the afternoon tomorrow
tomorrow in the afternoon
tomorrow afternoon

不对.直接说tmr afternoon

不用加介词了 直接说tomorrow afternoon

例如：
Tell him that he shall have the book tomorrow afternoon
告诉他他将会在明天下午拿到那本书

Do you have any time tomorrow afternoon?
明天下午有空吗？

直接说tmr afternoon就可以了

外语真的好难呀

不用in
tomorrow afternoon,后面加sentence就好了
