听力原文:M: Hey, Jane. What's so interesting?
W: What? Oh, hi, Tom. I'm reading this fascinating article on the societies of the Ice Age.
M: The Ice Age? There weren't any societies then, just groups of cave people.
W: That's what people used to think. But a new exhibition at the American Museum of National History shows that Ice Age people were surprisingly advanced.
M: Oh, really? In what way?
W: Well, Ice Age people were the inventors of languages, art and music as we know it. And they didn't live in caves. They built their own shelters.
M: What did they use to build them? The cold weather would have killed almost all of the trees, so they couldn't have used wood.
W: In some warmer climates, they did build houses of wood. In other places, they used animal bones and skins or lived in natural stone shelters.
M: How did they stay warm? Animal skin walls don't sound very sturdy.
W: Well, it says here, that in the early Ice Age, they often faced their homes towards the south to take advantage of the sun.
M: Hey, that's pretty smart! I guess I spoke too soon. Can I read that magazine article 'after you're done?
W: No problem.
