14. Read the telephone conversation between Marcus and his dad. Then put the verbs in brackets into the past simple or the present perfect. Listen and check.

Here's the solution to the conversation between Marcus and his dad: Dad: 1) Have you been (you/be) to the Valley of the Kings yet? Marcus: No, I haven't. But I 2) have already visited (already/visit) the Great Pyramids. They were beautiful! Dad: What else 3) have you done (you/do) so far? Marcus: Hmm..let's see. I 4) walked (walk) around the local Egyptian markets three days ago and I 5) went (go) on a Nile River cruise last night. Dad: Great! How's the food there? Marcus: I 6) have already tried (already/try) the traditional Egyptian food and it was very good. Dad: What are your plans for the rest of the week? Marcus: I 7) haven't seen (not/see) the Sphinx and I 8) am not visiting (not visit) the Egyptian Museum yet, so I would really like to do those things by the end of the week. Dad: Sounds good. Well, I have to go now, Marcus. Call me again soon. Marcus: OK, Dad! Bye! Translation and explanation: * Present Perfect vs. Past Simple: The exercise focuses on using the Present Perfect and Past Simple tenses correctly. The Present Perfect (e.g., "Have you been") is used for experiences within a time frame that isn't finished yet or when the exact time isn't important. The Past Simple (e.g., "walked") is used for completed actions at a specific time in the past. * Dad's questions: Dad uses the Present Perfect to ask about Marcus's experiences so far in Egypt. * Marcus's answers: Marcus uses both tenses. He uses Past Simple for specific completed actions like "walked" and "went" because he mentions specific times ("three days ago," "last night"). He uses the Present Perfect when referring to experiences up to the present moment, like "I have already tried."
