By the time I got to the doctor, the bee had already stung me on my arm.When the police arrived, the criminal had already shot two bullets into the air.The car accident had hurt my back so badly that I had to go to the hospital.By the time I returned the book to the library, it had already been lent out to someone else.The picture had hung crookedly on the wall for weeks before I finally straightened it.The window had been broken by the strong wind during the storm last night.
