1. My father was watching an interesting programme on TV, while I was reading for the examination. 2. We were playing the chess when the telephone rang. 3. My parents were having an unpleasant conversation when I came into their room. 4. Yesterday I was trying to beat the computer at chess all evening. 5. In the zoo the lions were being fed from 8.00 till 8.30 in the morning. 6. While we were having a swim in the lake, Mary was preparing a pleasant surprise for us. 7. When we were playing football, I suddenly broke my leg.
