1. A: Last summer, Jane went to London with her class. They have ridden the London Eye, have enjoyed the Science Museum and have walked in Hyde Park. They have taken lots of pictures. Would you like to see her photos?
B: I've already seen them. They are wonderful!
2. A: Have you been to his concert?
B: Not yet. But I was lucky last Monday. I have bought the tickets for his next concert. Would you like to go with me?
A: With pleasure.
3. A: Julia, I have phoned you yesterday.
B: Sorry, I missed it.
A: Was you at home?
B: No, I took my niece to the funfair. We were on rides and, then, we had lunch in the café. It was such fun.
A: I see. I have been to the funfair last weekend. And I liked it, too.
