Bonjour,
Réponse :
2)- She have been travelling for the three months.
- She have visited six countries so far
3)-Jimmy has been wining the n.championship four times.
-he has started playing since he was 10
Pour le 3 tu peux essayer toi même.
Bonne chance, il te sufffit de rajouter "has been" "has" dans les phrases.
