While cleaning the room yesterday, I _______ an old photo of my mother.
It’s nearly seven o’clock. Jack _____ be here at any moment.
They must have finished the work, ______?
-Is there a fog in the evening? -There ______ be. I’ll make a phone call to find it out.
-The door was open. -It ______ open. I had locked it myself and the key was in my pocket.
.-Mum, I climbed to get the Teddy Bear from the top of the shelf. -My goodness! You ______ yourself. You ______ do that next time.
