M: Good morning, Miss Smith. I'm sorry to trouble you.
W: Good morning, not at all. Please be seated. What can I do for you?
M: It's about my son.
W: He isn't in trouble. I hope he's doing well in all his lessons. He'll do well in the exams.
M: Except in Chinese, I'm afraid. He says that he is a little weak in Chinese.
W: Is he? I'm sorry to hear that.
M: That's why I've come to see you. I'm worried about his Chinese. He may fall the others when he comes back.
W: What do you mean?
M: We'll go back to London for a holiday for two months. We haven't been back for three years.
M: I see. I think that maybe his Chinese teacher can give him some homework to do during the holiday. He won't fall behind the others when he comes back.
