A、Taught her English herself. B、Went to talk with her teacher. C、Signed up for a language training class for her. D、Talked with

M: Hi, Sally! It’s been ages since we met last time. How are you getting along with everything?
W: It’s all right! And OK with you?
M: Yeah, but you look a little upset today. Anything wrong?
W: (19) Oh, I’ve got a problem with my daughter Christina. She’s seventeen now. And next year she’ll go to college. (20) But all in her mind are only fashions and boys but learning.
M: Sally, it’s quite normal for girls of Christina’s age to focus on the opposite sex and fashions alike. We used to be young, right?
W: But her grades slipped sharply. Without good grades, you’ll never enter a top university. Without college degree, how can you get a job, let alone a good job in the future?
M: Then I think what you need is to sit down and have a talk with her.
W: Talk about what? She knows everything.  Her father gets some money to send her abroad after graduation. Christina is surely clear about that!
M: But even if she will go abroad someday, she has to learn English well anyway, right?
W: That’s the headache! (21) I’ve signed up for a language training session for her already. Anyway, she has to work hard by herself.
M: (22) Why not talk everything with her teacher in school? It will help!
W: Great idea! I’ve never thought about that. I’ll take it to her teacher tomorrow. Thank you!
M: My pleasure. I did it for my son last time!
