we have borrowed the book for one week.
we have kept the book for one week.
we have lend it to you for one week.
which is right?
I think mabye we only can say ,"we borrowed the book one week ago."
we can't say,:we have borrowed the book for one week." right?
We borrowed the book a week ago
We have kept the book since last week
We have kept the book for a week
We are going to lend the book to someone else next week
We borrowed the book last week
Thank you. Now I understand it.
