Bonjour,
Réponse :
1)
I have already done babysitting for my little brother. I have often fed him, and I have also changed his nappies. I have often put my brother to bed when my parents are out, so I have read him stories many times or sung him lullabies. I have also worked for my neighbors. They have always been satisfied with me.
2)
a- I have never worked as a dogwalker.
b- She has done many odd jobs in her life.
c- I have never worked in a supermarket.
d- My sister has done babysitting twice.
e- We have not had a lot of experience. ( = We haven't had )
