这是澳大利亚土著词语，听Aaron解释一下吧。
Todd: Aaron, sometimes I hear from Australians, the term, have a walk-about, or walk-about!
Aaron: A walk-about is an aboriginal word. It basically, means an aboriginal boy, when he is growing up goes for a long walk, maybe for twelve months, and he doesn't see his family and he has to live off the land. He can't, he doesn't have money so he can't buy food, he can't buy anything, and he just hunts for food. It's not so common now, and I've never had to do it, but it's more of an old story from the aborigines who tell you about a walk-about.
Todd: Do you know anybody who's ever done it?
Aaron: No, I've never know anybody to do it, but I don't know if it's a true story or, I don't think it's common now, but maybe in the old days, maybe a hundred years ago, it was common for them to do it, but now they don't.
Todd: So, there's lots of different aboriginal people in Australia. Where does, which aboriginal tribe does this come from, or group?
Aaron: OK, I'm not sure what tribe it comes from but the aboriginals in the Northern Territories, which is all desert are probably the most famous for it, near Darwin and the top end we way, the north of Australia, where it's very mountainous, and you could walk for a year, and never find your way anywhere.
