The Present Perfect

A brief note on the expressions we found yesterday (Jan 13th) on the exercises. They're used in British English!!
They've made it! (=They've succeeded)
I've had enough (I'm fed up. I don't want to do it any more)
You've had it! (You're in trouble)
That's torn it! (You, we, they... have done something that someone else will strongly complain about)
Now you've done it! (You've done something seriously wrong)
She's arrived (She's achieved fame success, acceptance, etc, at last)
He's lost it (He's lost his patience or self-control)
You've got me there! (Good point: I've no idea what the solution is)
