F: I'm surprised to see you here. Jeremy told me that you were on vacation. ,M: Yeah. We were visiting some relatives in Sydney, but we return last night. ,F: Oh, I've wanted to go to Australia ever since I was little. Tell me what it was like. ,M: It was wonderful. We fed kangaroos, walkthrough rainforests and swam in the ocean. What was really great was when we took a train to Brisbane to see the Great Barrier Reef.
(A) F: I went to Australia when I was a child, but I didn't expect that the most impressive thing for you was to feed kangaroos. (B) F: Why is walking through the rainforest the most impressive thing for you? I've lived in Australia since I was a child, and I don't think the rainforests are impressive. (C) F: So visiting the Great Barrier Reef is the most impressive thing for you? (D) F: I am really sorry, I did not catch that. Would you slow down, please?

F: Uh, where do you think you're going? ,M: We're going to the new club, right? Oh, Man. I can't wait to get out on the dance floor and... ,F: Ha! You're not seriously going out like that, are you? ,M: Hey, you're just messing around with me, aren't you? Yeah, I know I look good. Just let me get my jacket. ,F: Jason, you look ridiculous. Your jeans are too tight, and they look like they were washed too many times, back in the 80s. And why are you wearing that funny hat? ,M: What? You've never heard of the New York Yankees? ,F: I'm a huge baseball fan. I know who the Yankees are, but why are you wearing that hat backwards? What are you 10 years old? And that jacket looks like a dead animal.
(A) M: I am afraid I did not quite catch what you were saying. Please repeat it. (B) M: I know you are crazy about baseball, but let's go to my parent's home first, OK? (C) M: Yes, I am crazy about baseball, too. Next time let's watch a baseball game together. (D) M: You are really crazy about fancy clothing brands. How about the Clippers hat I am wearing?
