Question

quiero saber como se formula una pregunta de presente progresivo y pasado progresivo

Answer 1

Si quieres formular preguntas en Presente progresivo solo tienes que colocar el pronombre entre el verbo auxiliar y el gerundio 

Ej:

Is HE Playing football? 
Are they cooking lasagna? 

Lo mismo haces con el pasado solo que en vez de colocar el verbo en presente lo cambias por su forma en pasado

Was he playing football? 
Were they cooking food?  

No sé si te sirva. 

Answer 2

presente progresivo:
Are you watching tv?
(estas viendo tv?)
recuerda que va así
am I...
is he
is she
is it
are we
are they
are you
pasado progresivo:
were you watching tv?
(estabas viendo tv?)
recuerda que va así
was I
was she
was he
was it
were we
were you
were they..
NO PUEDES OLVIDAR QUE LOS VERBOS VAN CON ING (GERUNDIO) AL FINAL, SIEMPRE!.
