BART : Hey Lisa, what did you do last weed-end ?


LISA : On Saturday morning, I was at home with Mummy and Maggie. We watched “ Krusty the clown ” on TV… Then, Milhouse telephoned and we talked for 45 minutes. We decided to go to the shopping center in the afternoon.
When we were in the Shopping center, we went to a “karaoke café”. We sang lots of sangs and we drank orange juice. It was very funny. Then, we went to “Ben and Jerry’s” and I ate chocolate ice-cream.
In the evening, I stated at home and I read a super detective book.

What about you ? What did you do last week-end, Bart ?


BART : Whit Dad, we were in the forest and it was really cool. We went for a walk, we fished and I swan in the river. We played cards and we talked a lot. I liked being with Dad. We a fire and cooked the fishes. At night, we played the guitar and we sang, then we slept in a tent.

Bonjour !

Je ne suis pas une super experte en anglais, mais je dirais que l'expression "last week end" montre bien que cela se passe dans le passé.

Bonne chance !
