hi!
1) I have worked all day, I'm so tired!
2) Alison has never worked in a supermarket before.
3) I have already done lots of odd jobs.
4) Jerry has not finished working yet.
5) I have been a dog walker since April.
6) Paul has worked as a delivery boy for three weeks.
7) Have you ever taken care of a dog before?
j'espère t'avoir aidé et bonne journée !
