Hey there! As your school teacher, I'd be happy to help you with this exercise. Let's start by filling in the gaps in the text, step by step:

Last year I went (go) on holiday. I __went__ to the sea with my friend. On the first day we __looked__ at the beautiful buildings and __ate__ in lots of restaurants. The next day __it was__ very hot so we __drove__ to the sea. We __left__ our clothes in the car and __sunbathed__ and __swam__ all day. At six o’clock we __walked__ to our car, but the car __wasn't__ there. We __bought__ some clothes and __went__ to the Police Station. The police __were__ nice and we __slept__ in the police station.

Now, let's explain the choices we made:

1. "I went" - We changed the verb "go" to its past form "went" because it happened in the past.

2. "looked" - We also changed the verb "look" to its past form "looked" for the same reason.

3. "ate" - Again, we changed "eat" to its past form "ate" because it happened in the past.

4. "it was" - We changed "be" to "was" to match the past tense.

5. "drove" - Similar to the previous changes, we changed "drive" to its past form "drove" because it happened in the past.

6. "left" - We changed "leave" to its past form "left" to match the past tense.

7. "sunbathed" - This is also the past form of "sunbathe" since it happened in the past.

8. "swam" - Like "sunbathe," this is the past form of "swim."

9. "walked" - We changed "walk" to its past form "walked" for the same reason as the previous verbs.

10. "wasn't" - This is the past form of "be" in a negative sentence.

11. "bought" - We changed "buy" to its past form "bought" because it happened in the past.

12. "went" - Similar to previous changes, we changed "go" to its past form "went" because it happened in the past.

13. "were" - This is the past form of "be" when referring to multiple police officers.

14. "slept" - This is the past form of "sleep" because it happened in the past.

I hope that helps! If you have any other questions, feel free to ask.
