Toate verbele (cu exceptia auxiliarelor si modelelor) formeaza interogativ si negativ cu ajutorul lui TO DO.
Iata cum se intampla la PREZENT, exemplu verbul TO SEE
Do I see? I do not see. [vad eu? Nu vad]
Do you see? You do not see. [vezi tu? Nu vezi]
Does he (she)(it) see? He (she) (it) does not see. [vede el/ea/? Nu vede] etc...
Do we see? We do not see.
Do they see? They do not see.
Acelasi lucru se intampla la TRECUT. Forma de trecut a verbului "to do" este DID.
Exemple:
Did I see? I did not see. [am vazut eu? Nu am vazut] etc....
Did you see? You did not see
Did he (she) (it) see? He (she) (it) did not see...
etc....
