Yesterday I met Jim. We ____________ each other since we _________ middle school.

---Pardon? I _____ quite catch you.--- I said I ______ the song before. 

---What’s wrong with Sally？  ---She was ill. She ______in the rain yesterday.

We won’t go to the park if it   ________ tomorrow.

—I phoned you at 7:00 this morning. But there was no answer.—Well, maybe I _________ morning exercises at that time.
