M: Hey, Liu Mei. I didn't see you at lunchtime, where were you?
W: I didn't feel like eating anything for lunch, so I just stayed in the classroom.
M: How about feeling now?
W; I'm much better, thank you.
M: We have been in this new school for several days, but we haven't seen our English teacher yet.
W: I hear she will be here tomorrow.
M: Really? Do you know anything about her?
W: Not much except that her father is a professor in Beijing University.
M: Is she married?
W: I have no idea.
M: What do you think of our new class?
W: Well, all our classmates are quite friendly. What do you think, Lin Tao?
M: There shouldn't be so many students in a class.
W: But that's the average size of a class in a high school.
W: You'll have to get used to it.
M: I guess so.
