Решение:

• 1. Philip was washing the car when the fire started. (Используется 'when' для обозначения действия, которое прервалось другим действием.)
• 2. Neil was studying when his sister was listening to music. (Используется Past Continuous для обозначения двух одновременных длительных действий.)
• 3. Harriet was opening the door and opened it and walked into the house. (После 'and' следует действие, которое произошло сразу после открытия двери, поэтому используется Past Simple.)
• 4. We were having lunch at a lovely restaurant every day when we went on holiday. (Глагол 'having' здесь подразумевает разовое действие, а не регулярное, поэтому используется Past Simple.)
• 5. Brian drank tea at five o'clock yesterday afternoon. (Действие в Past Simple, так как оно завершено в прошлом.)
• 6. Dad was repairing the TV while Mum was cooking dinner. (Два одновременных длительных действия в прошлом.)
• 7. I went to the cinema last Saturday. (Действие в Past Simple, так как оно произошло в определенное время в прошлом.)
• 8. I was buying a new dress for my party yesterday. (Действие в Past Continuous, указывающее на длительность процесса покупки.)
• 9. While Jeff was building the garden shed, he hurt himself. (Действие 'built' было прервано, поэтому используется Past Continuous.)
• 10. While the teacher was speaking, the students were listening to him. (Два одновременных длительных действия в прошлом.)
