For questions and negative statements in the Simple Past, the Simple Past of the auxiliary to do is used. The Simple Past of to do is conjugated as follows:
I did |
you did |
he did |
she did |
it did |
we did |
they did |
In order to change an affirmative statement into a question, did is placed before the subject, and the form of the verb is changed from the Simple Past to the bare infinitive. In the following example, the regular verb to work is used. The verb to work has the Simple Past worked, and the bare infinitive work.
Affirmative Statement | Question |
I worked. | Did I work? |
You worked. | Did you work? |
He worked. | Did he work? |
She worked. | Did she work? |
It worked. | Did it work? |
We worked. | Did we work? |
They worked. | Did they work? |
Exercise:
Paying attention to the correct forms of the bare infinitives, change the following affirmative statements into questions. For example:
He lifted the suitcase.
Did he lift the suitcase?
I paid the rent.
