Om een ontkenning te maken in de past simple heb je het hulpwerkwoord 'did' nodig, je zet namelijk altijd
did not of de afkorting
didn't voor het
hele werkwoord (zonder -ed dus):
I did not / didn't watch tv last night.
You did not / didn't watch tv last night.
He did not / didn't watch tv last night.
We did not / didn't watch tv last night.
You did not / didn't watch tv last night.
They did not / didn't watch tv last night.
