Input: F: Hello, Sam. How are your exam preparations coming along? ,M: Good, Miss Swift. I've been working hard for it recently, I'm sure that the exam won't cause much trouble. ,F: Excellent. So are you working at the weekends now to get some pocket money? ,M: Yes, I'm very grateful to Mr. Lam, he really helped me with my problem. ,F: Mr. Lam said that your problem was that you had no pocket money. Is that right? ,M: Yeah, I couldn't go out with my friends. Because I didn't have the money for the bus fare. But I'm OK now with a part-time job. ,F: So you think the student's welfare club really helped you? ,M: Oh, yes, I have no complaints about the club. I think you are fantastic. ,F: Thank you, any suggestions as to how we can be even more fantastic? ,M: Why don't you have a ladder box outside the club's room, that way we can keep in touch with you even if we don't get to see you? ,F: That's a great idea. It won't cost anything to put a letter box outside. OK. Thank you for your time, Sam.
(A) M: Yeah, it won't cost anything to put a letter box outside. That's why I offer the advice of putting a letter box outside the club's room. (B) M: Yeah, it will cost something to put a letter box outside. So, my advice is to put up notices in the campus. How do you think about it? (C) M: Really? You mean you think that's a bad idea? Okay, I see. But I think the advice of opening more club rooms is useful. (D) M: I’m sorry, I didn’t catch that. Would you mind speaking more slowly?
