Comment former le conditionnel passe en anglais ?

Comment exprimer un regret en anglais au passe ?
Utilisez 'should have' ou 'shouldn't have' + participe passe : I should have called earlier. She shouldn't have made that mistake. You could have warned me. Ces formules expriment ce qu'on aurait du faire differemment.
'Would of' ou 'would have' : lequel est correct ?
'Would HAVE' est la seule forme correcte. 'Would of' est une erreur tres frequente, probablement due a la contraction orale 'would've'. A l'ecrit, toujours ecrire 'would have' en toutes lettres ou 'would've'.

Inversez le sujet et WOULD : Would you have accepted the offer? Would she have known the answer? What would you have done in my place? Where would they have gone?
