Complete the dialogue by filling in the blanks with the correct form of "used to" and the appropriate verb form from the words in brackets. Let's look at each sentence one by one:
A: My grandparents used to live in a small village.
- Here, "used to live" is used to indicate that living in a small village was a habitual action in the past.
B: What did they use to do in their free time?
- In this question, "did they use to do" asks about habitual actions in the past. Note that when forming questions in the past, "use to" is paired with "did."
A: They read a lot. They didn't use to have a TV. Once a week, they used to go to the cinema.
- "Didn't use to have" is the negative form, indicating that not having a TV was true in the past.
- "Used to go" shows a regular past activity, going to the cinema every week.
B: Did they use to go anywhere after that?
- Again, this is a question form asking about past habits, so it uses "did they use to go."
A: No. There didn't use to be any clubs or discos in the village.
- "Didn't use to be" is a negative past habitual form indicating the absence of clubs or discos in the past.
This dialogue uses the construct "used to" to talk about habits or states that were true in the past but are no longer the case. The negative form is "didn't use to," and when asking questions, we use "did" as the auxiliary verb.
