M: I'm really bored at the moment. ,F: Let's play a game. I'll describe someone and you try to guess who it is. OK, this man is tall and thin, he has blue eyes and curly brown hair. ,M: Does he have a mustache or a beard? ,F: Good question, yes, he has a mustache, but no beard. ,M: Sounds like Mike, doesn't it? ,F: Yes, you're right. Now, you describe someone we both know. ,M: OK, she's not very tall, but she is a little heavy, she has blonde hair. ,F: I don't think I know anyone like that. ,M: And she wears fashionable shoes, in fact, she wears fashionable clothes too. ,F: This doesn't sound like anyone I know. I give up, tell me who she is. ,M: She's your mother. ,F: Huh, that's actually a pretty good description, but it's embarrassing that I couldn't figure that out, my own mother. Do you think appearance is the most important thing about a person? ,M: No, but it's more important than a person's character in the game we're playing.
(A) F: Right, person's appearance is more vital, so we mentioned Lucy and your father, who's next we are going to talk about? (B) F: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (C) F: Yes, we should focus on more the character of person, for example, you should tell me more when you mentioned Mike's mother just now. (D) F: Well, a person's career is really important, so we should talk more about the person you mentioned a few minutes ago, that's Alice, right?
