2 While everyone was sleeping, Paul watched TV
3 I was dreaming of a long vacation when the alarm clock went off
4 While I was practicing the piano late last night, I heard strange noise
5 The sheep were grazing in the field when they were scared by the noise
6 What were you doing when the earthquake happened yesterday
7 I was running to catch the bus when I saw him
8 When you met James last night, what was he wearing
9 Some people were chatting while the others were playing games at the party last night
10 It was raining at this time yesterday so we cancelled the barbecue
