I first met Lisa three years ago. She ________ at a radio shop at the time. 

 I enjoy       around the lake when I go to that park every time.

—Can you tell me if Tom has finished his homework?—I've no idea. He ________ it this morning.

He was hoping to go abroad but his parents ________ that they won’t support him unless he   can borrow money from the bank.

I saw him in the library yesterday.  He ________ a book at that moment.
