F: Hey, Paul, you're still having Thanksgiving dinner at my house on Thursday, right? ,M: Yeah, thanks again for the invitation. I was worried I'd have to spend it alone after my parents announced they'd be in Finland. ,F: I think it's strange that you're not going with them. Is it because of the cold weather in Northern Europe? ,M: Not exactly. I have a lot of work to do next week. ,F: Well, I'm glad you won't be alone on a holiday. It'll be great to have you celebrate with us. The more the merrier! ,M: Exactly, how many people will be there? ,F: Let's see, my parents, my grandpa, my sister, my brother-in-law, my niece and my two cousins, plus us.

F: Sam, where's the closest ATM? ,M: It's not that far. Do you see that yellow building over there? It's next to it, on the right. ,F: Oh, I see. Do you know if there's a convenient store around here? ,M: Well, you could go down to twenty second street. There are a lot of stores down there that are open 24 hours a day. ,F: Can I take the subway to get there? ,M: Yes, but that will probably take about half an hour. You should just take a taix. ,F: Won't that be expensive? ,M: No. From here I think it's only about $5. ,F: OK, I will go there by taix.
(A) M: I’m sorry, I didn’t understand. Could you repeat a little louder, please? (B) M: So you decide to go to the store by subway? Fine. It needs only ten minutes. (C) M: Tell the taxi driver to find the store. There's only one store on the 21nd Street. (D) M: Good choice. You'll find taxi very convenient and you can pay in cash or card.
