Simple Past (Yes / No Questions)

When you want to ask about something in the past. We make past simple questions using DID.

Did + Subject + Verb infinitive

Did you eat? Yes, I did / No, I didn´t

We use WAS / WERE to ask Yes / no questions when the verb is BE.

Form:

Was + I, he, she, it

Were + You, we, they

Yes, she was / No, she wasn´t

Were you at the park on Sunday?
