[speaker001:] It's wonderful to be in the mountains after a hustle bustle week.
[speaker002:] Indeed. I love the smell of the grass and trees. They certainly refresh my mind.
[speaker001:] Can we stop here for a while? My backpack is very heavy.
[speaker002:] Sure. Did you hear anything? Look! An eagle is hovering in the sky.
[speaker001:] Let me see. It's not an eagle. I think it's a vulture.
[speaker002:] Yes. Will it hurt us?
[speaker001:] I don't think so. Let's walk by the stream. I am sure we can find the waterfall on the map.
[speaker002:] OK. I have a good pair of hiking boots. It should not be a big problem.
[speaker001:] I also brought a bottle of water and some provisions. If you are hungry, you can let me know.
[speaker002:] You are kind. Look there is a big tree over there, it looks like a thousand-year-old tree.
[speaker001:] Well, it is a birch tree.It is not as old as you think.
[speaker002:] How do you know?
[speaker001:] Because its trunk is not thick enough to be like a thousand-year-old tree.
