听力原文：OK, as you all know, tomorrow we're be going to the museum to see a special exhibit of screemshore carvings. So today, I'd like to take a few minutes to talk about the article on screemshore you read for today’s class. Let me start by asking exactly what is screemshore？
Well, basically it's a kind of artwork that was done by sailors on whaling ships. When there weren't any whales around, there might not be much for the sailors to do and they often get pretty bored. So to entertain themselves, they started carving stuff on whale bones and whale teeth.
OK, so basically the term screemshore refers to the artwork that sailors created. Usually out of whale bones and whale teeth. Can you give me an example or something that sailors might have carved.
Well, for one thing, I remember reading that they carved things that could be used around house, you know, cooking and sowing utensils, that kind of stuff.
Good.
You know, I noticed from the pictures in the article that some of the carvings have really detailed images on them, like they have some pretty sophiscated pictures of famous people and historical themes and stuff like that. And I was wandering just how they did that.
That's a very good question and it brings us your assignment for tomorrow. While at the museum, I'd like each of you to take some notes on the various technique used in making screemshore. So that we can discuss them when we come back to class.
