A、Because you can try to practice your pronunciation with them. B、Because some of them may show you the wrong way. C、Because you

W: So Greg, you are quite a world traveler I hear.
M: Um, yeah, I love traveling. I’ve been to probably around, I don’t know, 20 different countries. I’ve lived in Thailand and South Korea and the United Arab Emirates (阿联酋), and four different parts of Japan.
W: Oh, that’s a lot.
M: And of course several different places in the US.
W: Well, for somebody who’s going to travel for the first time, what advice would you give him, in case he gets lost?
M: Ah, getting lost. Yeah, that happens all the time. You have to prepare for that. One of the first things I do whenever I get to an airport is I see if I can get a map from the information center, or when I go to a hotel, I ask if they have a map of the area.
W: That’s quite considerate (考虑周到的).
M: When I want to go somewhere, I ask them to write the destination in the local language, and also I practice my pronunciation with them, and sometimes I’ll get a business card from the hotel.
W: OK, well, let’s say that, um, you’re on business in a foreign country, and you’re really busy and you forget to get the business card, you don’t have the map, you’re trying to find a place and you’re completely lost, what should you do?
M: Well, of course, you’ve got to ask people. And it’s a good idea to ask a lot of different people because in some countries people don’t want to say no, and they don’t want to say "I don’t know," either. They may give you the wrong directions.
W: Well, so when you’re going down the street, and say you are lost, is there a certain person who is better at giving directions?
M: Um, well, if it’s a child, and you want to get to a business section or something, probably he doesn’t know. It’s a good idea to ask some adults who look as if they live in the area.
W: Right. So you’re talking about people who work in shops and things like that?
M: Yes, and also, delivery men are usually very good, because they have to go all over the city, so they know it well.
W: Right. So have you actually ever been lost?
M: Oh, I’ve been lost all the time. Once I got lost for a couple of hours in Bangkok, and it was terrible.
W: Well, that’s a densely populated city.
M: Yeah, so after that, it gave me the idea that I should always check for landmarks (地标). You know landmarks are really tall buildings, or a river, something I could always know, and I could see easily.
W: Well, it sounds like good advice. Thanks, Greg.
M: You’re welcome.
