"We have to be at the school by nine o'clock sharp."
"我们九点整要到学校." is also a right answer, yet it is marked as wrong here. Please fix.
exactly, and the clause that indicates time is even more common after the subject than in the beginning in a daily speech
我们要九点整到学校。that was marked as incorrect and now my shortcut test has failed...
I said "我们九点钟需要在学校到。” Which I think would be "We need to arrive at the school at (exactly) 9 o'clock." Am I wrong?
