M: Doctor Wilson, can I talk to you for a minute? ,F: Sure, Fred. What is it? ,M: I'm worried about my grade in your English Class. I really want an A, but. ,F: I see. Well, it might be hard for you to get an A. So far, you have a B average. You would need a 97 or 98 on your final exam to get an A. Do you think you can get that higher score? ,M: Probably not. The problem is that I have to have a B average in all the subjects to get the prize from our government. Otherwise, I'll have to find a part time job. I'm afraid it is difficult for me to put all my heart in my study if I have to work in my spare time. I'll probably get an A in history and a B in maths, but I'll get a C in chemistry.
(A) F: I am really sorry, I did not catch that. Would you slow down, please? (B) F: Sounds great that you can get A in history and maths. Happy for you! (C) F: You must have put in a lot of effort to get A in maths and chemistry! (D) F: Don' t be sad! At least you can get an A in history. Everything will be alright!

M: Excuse me. How can I get to the bank? Bank of America, I mean. I don't know the way. ,F: Well, go straight ahead till you see a supermarket. The bank is just on the other side of the street. ,M: Is it far from here? ,F: Let me see. Uh, it's 14 blocks away. Not very far, but not very close, either. ,M: Can I take a bus or something? ,F: You can take bus number 104, or streetcar B201. It's 4 stops away by bus and 3 stops away by streetcar. ,M: But where can I take the streetcar?
(A) F: I'm sorry, I didn't catch that. Would you mind speaking more slowly? (B) F: So you choose to take streetcar B102 because it is 4 stops away by streetcar, right? (C) F: So you choose to take streetcar B201 because it is 4 stops away by streetcar, right? (D) F: So you choose to take streetcar B201, don't you?
