Friend: Hi, Dave, it's me. I'm ringing to ask you about the sports day.
Dave: It was fantastic! I had a great time.
Friend: Did you take part in anything?
Dave: I was in lots of things.
Friend: Did you win anything?
Dave: Yes, I did. I was the 100 metres champion.
Friend: Great! And what about swimming?
Dave: Imagine, Keith set a new school record!
Friend: Really?!
Dave: Yes. And he was the second in the volleyball competition.
Friend: My congratulations!
Dave: Thanks. Well, it was a real pity you couldn't come. You know you can swim so well. You can easily win a medal for us.
Friend: And who won the football game?
Dave: Er, I can't remember. Oh, no, I think someone from class 5. Andy tried really hard. Well, but he was just able to come third.
Feel free to ask if you need any more help!
