Bonjour
past simple : pour une action passée terminée, une action courte
past continuous ; pour une action passée qui "était en train de se faire"
1- We lost all the power.
2- But it came on again after ten minutes.
3&4- Vicky: Rachel was coming down wen the lights went out.
5- She almost fell over.
6- Matthew and I were playing table tennis at the same time.
7->10- Andrew : I was working on my computer. I lost a whole hour's work but this morning I got up early and I did it again.
bonne journée ☺☺☺
