Read and listen to the dialogue. Why does Mason change from feeling anxious to feeling terrified?
Ruby: So, this is your first school show, Mason. Are you excited about it?
Mason: Yes, I am. But I'm anxious too. There's going to be a big audience!
Ruby: Don't worry. They’re friendly!
Mason: I hope so. Where’s Alex? He isn't here yet.
Ruby: That's strange. He's usually very punctual.
Mason: Maybe he's too frightened to come.
Ruby: Alex? No, it can't be that. He's a really confident person.
Miss Hart: Hello, Mason. I had a message from Alex. He’s ill and can't perform tonight. He's very upset about it. Can you sing this song in the second half?
Mason: I know the song well, so maybe…
Miss Hart: Thanks, Mason. That's brave of you. Don't worry, you’ll be great.
Ruby: You've got your own song now. How exciting!
Mason: I know. But I'm terrified!
Because Alex can’t come, and she has to sing his song before a lot of audiences without practicing before.
(Bởi vì Alex không thể đến, và cô ấy phải hát bài hát của anh ấy trước nhiều khán giả mà không có sự luyện tập trước đó.)
