Here is the correct transformation of the verbs in brackets into the Past Simple tense. Below, I'll also provide an explanation of why each verb is conjugated the way it is:
Pamela: What did you do (you/do) last weekend?
Explanation: Since the question is in the Past Simple, we use the auxiliary verb "did" + the base form of the main verb "do."
Tony: I went (go) to my cousin's house.
Explanation: The verb "go" is irregular, and its Past Simple form is "went."
Pamela: Was (be) it far?
Explanation: The verb "be" in the Past Simple changes to "was" (for singular subjects like "it").
Tony: No, it only took (take) us 30 minutes.
Explanation: The verb "take" is irregular, and its Past Simple form is "took."
Pamela: Did you stay (you/stay) there long?
Explanation: When forming a question in the Past Simple, we use "did" + the base form of the main verb "stay."
Tony: We stayed (stay) only for the weekend.
Explanation: The verb "stay" is regular, so we simply add "-ed" to form the Past Simple ("stayed").
Pamela: What did you do (you/do) last weekend?
Explanation: Similar to the first question, we use "did" + the base form of "do" to form a Past Simple question.
Pamela: My family and I took (take) the dog and we had (have) a picnic on the beach.
Explanation: The verb "take" is irregular, and its Past Simple form is "took." Similarly, "have" is also irregular, and its Past Simple form is "had."
Tony: Was (be) it sunny?
Explanation: The verb "be" in the Past Simple changes to "was" (for singular subjects like "it").
Pamela: Yes, the sun shone (shine) all day.
Explanation: The verb "shine" is irregular, and its Past Simple form is "shone."
