Robert wishes that he ________ business instead of history when he was in university.
I saw him ______ at desk, reading.
I used to drink a lot of tea but these days I ______ coffee.
--- Did he notice you enter the room? --- I don’t think so. He ______ to the radio with his eyes shut.
--- Alice came back home the day before yesterday.--- Really? Where ______?
--- I will come to attend your lecture at 10:00 tomorrow. --- I’m sorry, by then my lecture will have ended and I ______ my guests in my office.
