M: Thank you for calling the Hillside Gallery. How can I help you? ,F: Hello. Is there a photography exhibition this weekend? ,M: Yes, there is. ,F: How much is the ticket? ,M: Tickets for the gallery are 10 pounds and half price for children, but this includes the painting exhibitions, too. If you only want to see the photography exhibition, it's 7 pounds per person, with half price for children, too. ,F: The gallery's on Flower Street, isn't it? ,M: No, we moved to a different building last year. Our present address is 25 Gardenia Road. It's opposite to the Town Square. ,F: Oh, I see. Does the number 25 bus go by it? ,M: Yes, but I suggest you not take a bus or drive here. You will be stuck in a traffic jam at weekends on this street. The underground is easy and fast.
(A) F: Sure, I will take the bus there as you suggested since it's faster and cheaper. (B) F: I hate traffic jam. In that case, I shall take the underground to go to your gallery. (C) F: I'm sorry, I didn't catch that. Would you mind speaking more slowly? (D) F: So you think it's better driving there since neither bus nor subway goes there.

M: Hasn't it been hard for you without your sister and brother, mom? ,F: Yes, Sam, of course. We haven't seen each other for a long time. ,M: Mom, I have a surprise for you. I'll go on a business trip to Russia. I want you to come with me. You can meet them finally. ,F: No, Sam. It's very thoughtful of you, but I'm too old and sick to travel so far.
(A) M: Really? You don't think you are old and sick to travel? And you refuse my invitation because you haven't prepared for the trip? (B) M: OK, I see. You refuse my invitation because you are unsuitable for such a trip and you think you are too old and sick to travel so far. (C) M: I am sorry. You spoke so rapidly that I did not catch the meaning of what you said. Could you repeat that? (D) M: Really? You think you are not sick to travel but you refuse my invitation because you prefer to travel with your sister?

F: Oh, heavens, I look terrible. ,M: Come on. I'm sure it's not that bad. Can I come in and take a look, honey? ,F: Absolutely not. This shirt looked pretty nice on the shelf. But on my fat body, it looks terrible. ,M: I thought you like the styles from the eighties. ,F: I like good eighties styles. Not bad eighties styles. ,M: I never knew that you could divide it up like that. I just thought all eighties styles were good. ,F: Very funny. Look, can we just get out of here please? Let's just try to find a more modern store where they might actually have something that doesn't make me look like some huge cartoon animal from the zoo. ,M: It's all up to you.
(A) F: Thanks for coming in to get the shelf from me. (B) F: I am afraid I did not quite catch what you were saying. Please repeat it. (C) F: Thanks for coming in to give me some advice. (D) F: Thanks for coming in to give me some advice, dad.
