Explications:
Bonjour,
1. Our cats don't eat tinned food.
2. I don't text my friends during class.
3. Paul doesn't his homework late at night.
4. Jerry don't post a lot of photos on Facebook.
5. My mum doesn't go to the supermarket on Saturdays.
Après, si tu veux écrire l'auxiliaire do en forme longue, tu vas dire " do not" pour don't et "does not" pour doesn't.
J'espère t'avoir aidé.
