Can we say 你明天晚上想干什么？
I agree. The previous exercises could not distinguish when time was mentioned before he subject, and only accepted when it was before the verb. Now it's not accepting when we out time before the verb.
It is correct. i've tried it
Has been accepted for me, although I think in.chinese time specifications.usually come.first
We can and it is accepted.
Yes, you can
Time point (when the action happens) can go either before or after the subject. The emphasis is a bit different in each case.
What's the difference between 干 and 做?
They both mean "to do", but 干 also means "fu_k," or "what the f_ck are you doing?" so at least in 臺灣 most people say "做"
