Tom: How are you, Mr. Green?

Green: Fine, thanks. And you?

Tom: Very well, thank you.

Green: Do you know Mr. Lee?

Tom: Sorry, I don't know him.

Green: This is Mr. Lee. He is a teacher. This is Tom.

Lee: How do you do, Tom?

Tom: How do you do, Mr. Lee? Are you from America?

Lee: No, I'm from England. Are you a teacher, too?

Tom: No, I'm a student here. I'm in Grade Two.

Lee: But you speak Chinese very well. Welcome to China!

Tom: Thank you. Oh, it's time for class. See you later!

Lee: See you!
