1. Listen and act out in a group of four.

Lilly: That was an interesting lesson! I really like History — it's my favourite subject. After English, of course.
Mary: As for me, I don't like memorising the dates. I got a really bad mark for the History test.
Chris: Never mind, Mary. You might have a good mark next time. Anyway, you can ask your teacher to improve the situation.
Lilly: Well, we decided to visit Terry on Saturday, didn't we?
Chris: We did. Let's meet at four.
Mary: OK.

Lilly: Hi, Terry. We thought you might be lonely without John, so we came by to cheer you up.
Terry: Thanks.
Chris: Have you had any news from John? You said that he and his parents had gone to Lviv for a few days.
Terry: Yes, he phoned me last night.
Mary: What did he say?
Terry: He said that he really liked Lviv. He told me that he was having a great time.
Chris: Why did they go there?
Terry: He said that his parents had studied at Lviv University. They were visiting their old university friends.
Lilly: When are they coming back to Kyiv?
Terry: I'm not sure, but John said that he would see us at school on Wednesday. Maybe he'll bring us souvenirs.
Mary:
I hope so. Listen, why don't you come to my house on Monday? We can
talk about the theme of the following Radio Discussion Club programme.
Lilly: Great! I guess that's better than staying in the classroom after the lessons.
