Past Tenses

They left after they ___________ the problem.

Last summer, some friends and I _____________ to go camping.

Bill ________________ the front door when the telephone rang.

Sally ________________ to the ballet club three times a week.

I _________________ for days before you phoned me.

Last Friday, I ________________ in the park when I saw my old friend.

He was so tired yesterday. He _____________________ on this project for 4 hours.

Charlie _______________ home before Ann finished cooking.

When I came home, I saw nobody. It seemed that everyone ________________ not less than an hour before
