Basics: Used To - Past Habits and States: correct answers
Jump to answers ↓Basics: Used To - Past Habits and States
We use "used to" to talk about habits that happened regularly in the past or states that were once true but have since changed. For example, "I used to play the piano every day" (a past habit) or "He didn't use to like broccoli" (a past state). Notice how the negative form and questions drop the 'd' with the auxiliary verb "did", as in "Did she use to live here?".
This challenge covers how to correctly structure affirmative, negative, and interrogative sentences with this grammar pattern. You will explore past habits and states through a variety of fun scenarios, ranging from everyday topics like drinking coffee, eating habits, and using smartphones to imaginative situations involving time travel, superheroes, and aliens.
You'll work through 15 questions presented in single-choice, multi-choice, drop-down, and drag-and-drop formats.

Correct answers
Question 1
Before the radioactive spider bite, I used to wear thick glasses.
"Used to wear" shows a past state (wearing glasses) that has completely changed in the present.
I also didn't use to have any muscles at all.
For the negative form, we use "didn't use to" (without the "d" on "use"). It shows a past state that wasn't true before, but is true now!
Question 2
Complete the journalist's interview questions for our new alien visitor.
I am very curious, Zorg, did you use to fly a spaceship to school? Also, where exactly did they use to park all the UFOs on your home planet?
I am very curious, Zorg, did you use to fly a spaceship to school?
In questions, we use "did" + subject + "use to" (without the 'd' on 'use').
Also, where exactly did they use to park all the UFOs on your home planet?
Just like the first question, "did" already carries the past tense, so "use" stays in its base form.
Question 3
The correct answers are Did you use to ride a T-Rex to work? and Did people use to keep velociraptors as pets?
To ask a question about a past habit, we use Did + subject + use to + base verb.
Because "Did" already shows us that the sentence is in the past tense, we drop the "d" from "used" and simply write "use to".
Question 4
Complete the confession of a nostalgic older sister.
When we were kids, my brother ___ think that broccoli was made of tiny trees, and he would refuse to eat the "forest."
The correct answer is used to.
We use "used to" + base verb (think) to talk about past habits or states that are no longer true. "Use to" is only correct in questions (with did) or negative sentences (with didn't).
Question 5
"Grandpa, did you use to memorize all of your friends' phone numbers?"
To form a question about a past habit, we use Did + subject + use to + base verb. Because "did" handles the past tense, we use "use" without the "d".
"And where did you use to go for fun before the internet was invented?"
Even with question words like "where," the rule stays the same: Wh- word + did + subject + use to.
Question 6
Before college, I didn't use to drink coffee at all.
In negative sentences, we use "didn't" (did not). Because "did" is already in the past tense, the main verb drops the "d" and becomes "use to".
I also didn't use to care about getting enough sleep...
Remember the formula for negative past habits: Subject + didn't use to + base verb. Plausible-sounding options like "didn't used to" are grammatically incorrect in standard English!
Question 7
The correct answers are People used to believe a ghost lived in the attic. and The mansion used to belong to a wealthy pirate.
"Used to" is perfect for describing past states (like "believe" or "belong") that are no longer true.
We cannot use "would" for past states (only for past repeated actions). Additionally, "was used to" means "was accustomed to," which doesn't fit here and requires an -ing verb anyway!
Question 8
Before college, I didn't use to drink coffee at all.
In negative sentences, we use "didn't" (did not). Because "did" is already in the past tense, the main verb drops the "d" and becomes "use to".
I also didn't use to care about getting enough sleep...
Remember the formula for negative past habits: Subject + didn't use to + base verb. Plausible-sounding options like "didn't used to" are grammatically incorrect in standard English!
Question 9
When I was a little kid, I used to think that the moon followed my parents' car.
We use "used to" + base verb to talk about past states or habits that are no longer true. Notice that we spell it with a "d" in affirmative sentences!
My younger brother and I used to argue in the backseat about who the moon liked better.
Again, "used to" describes a repeated action in the past (arguing) that doesn't happen anymore.
Question 10
The correct answers are We used to practice in my parents' garage every Friday. and We practiced in my parents' garage every Friday.
Both used to + base verb and the Past Simple ("practiced") can be used to describe repeated past actions or habits.
"Are used to" is present tense and requires an -ing verb. "Used to practicing" is incorrect because "used to" for past habits needs the base verb, not an -ing verb.
Question 11
Help the famous food critic confess her childhood eating habits to her readers.
Believe it or not, I didn't use to like vegetables at all. In fact, I only used to eat plain pasta and cheese!
Believe it or not, I didn't use to like vegetables at all.
The negative form is "didn't use to" (without the 'd' on 'use' because "did" already shows the past tense).
In fact, I only used to eat plain pasta and cheese!
For affirmative statements, we use "used to" + bare infinitive.
Question 12
Choose the correct phrase to complete the teenager's interview with their grandfather.
Grandpa, ___ memorize everyone's phone numbers before smartphones were invented?
The correct answer is did you use to.
When asking a question about a past habit, we use the auxiliary verb did + subject + use to (base form). Remember, because did is already in the past tense, we drop the "d" from used!
Question 13
The correct answers are didn't use to eat and never used to eat.
For negative past habits, we use didn't use to + base verb or never used to + base verb.
Notice that after "didn't", we drop the "d" and just write "use to". "Didn't used to eating" mixes up different grammar rules, and "wasn't used to" means "wasn't accustomed to" and requires an -ing verb.
Question 14
Complete Grandpa Joe's slightly exaggerated memoir about his youth.
My grandfather used to be a famous magician. He used to pull rabbits out of his hat every single Sunday!
My grandfather used to be a famous magician.
We use "used to" + bare infinitive to talk about past states that are no longer true.
He used to pull rabbits out of his hat every single Sunday!
We also use "used to" + bare infinitive to describe past habits or repeated actions.
Question 15
Complete the local tour guide's dramatic story about the town's history.
Believe it or not, this boring dental clinic ___ a terrifying haunted mansion back in the 1980s!
The correct answer is used to be.
"Used to" shows that a state existed in the past but doesn't anymore. Because we need a main verb to connect the subject (clinic) to the noun phrase (a terrifying haunted mansion), we must include the verb "be."
