Formación

Afirmativo

Sujeto + should/would + have + past participle del verbo + ...

Para la primera persona del singular y plural se utilizan indistintamente "should" y "would" aunque la tendencia es a usar "would" para todas las personas.

En inglés americano normalmente no se usa "should".

En las formas afirmativas contraídas esta distinción no se nota ya que sólo queda la -d final.

Ejemplo:

Forma larga Forma corta
I should/would have worked I'd have worked
You would have worked You'd have worked
He would have worked He´d have worked
She would have worked She´d have worked
It would have worked It'd have worked
We should/would have worked We'd have worked
You would have worked You'd have worked
They would have worked They'd have worked

Negativo

 

Forma larga Sujeto + should /would + not + have + past participle del verbo + ...
Forma corta Sujeto + shouldn´t/ wouldn´t + have + past participle del verbo + ...
Forma larga Forma corta

You would not have worked You wouldn´t have worked
He would not have worked He wouldn´t have worked

It would not have worked It wouldn´t have worked
We should/would not have worked We shouldn´t/ wouldn´t have worked
