dåtid uttryckt med did + infinitiv

Ett vanligt sätt att uttrycka dåtid på engelska är att använda preteritum (imperfekt/igår-formen).
Ex. 1: I watched the movie Grease.
Ex. 2: He played the guitar very well.
Ex. 3: Aron said that he went to school every day but his parents thought he was lying.

Dock ersätts preteritum med did + infinitiv...
...i frågor: Did you watch the movie Grease?
...i negativa satser: He did not play the guitar very well.
...för att betona: No, you are wrong! I did go to school yesterday!
