This is the first time that I have posted thread in here. I would appreciate it if anyone helped me. And I'd like to share with you what I see and hear.
Here is the excerpt from our textbook:
I'm Peter Penguin...In summer the sun shines all the time. We have no night at all. Then comes our winter. It is at night all the time...
I wonder if it is correct to say "it is AT night all the time."
