This tutorial is focusing on the auxiliary “did” past simple, and how to use it in negative and question forms.
Peter answers the door. Sara and her friend Jeanne are on the doorstep. How are you Sara and how are you, Jeanne?
Sara is an English language teacher and Jeanne teaches French. They teach in the same school.

They leave their things in the hall. They take the bottle of fizzy water and go to the kitchen.
What did you do this week Sara? I did the usual things. You did your work then? Did it take a long time?
It did, Jeanne did you enjoy your week? Yes, I did. I love London and Sara helps me such a lot with my English.
What did she teach you? We did the auxiliary verb do. That’s funny, did you learn a lot? Is it easy.
“What do you do?” is in the present and “What did you do?” is in the past.
I did, you did, he, she, it did, we did, you did, they did. It doesn’t vary. It didn’t take long to learn, did it Sara?
No, it didn’t. You did very well, didn’t you? Yes, I did, thank you so much.
Let’s learn how to form the simple past negative and question forms!
We use the auxiliary “to do” in the past simple: “did” to create the negative and question forms of regular verbs:
I did, you did, he did, she did, it did, we did, you did, they did
I did not, you did not, he did not, she did not, it did not, we did not, you did not, they did not
I didn’t, you didn’t, he didn’t, she didn’t, it didn’t, we didn’t, you didn’t, they didn’t
I did not laugh. I didn’t laugh.
Did you laugh? Didn’t you laugh? Did you not laugh?
Simple past forms:
S + did not / didn’t + bare infinitive (infinitive without “to”) + O.
