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.
