1 . Many centuries ago, all people had to gather seeds and plants to eat. They did not know how to farm or raise animals for food. We call them the Stone Age people because they used stone tools and weapons.

You may feel surprised in the world today there are still people who live like the Stone Age people. They live in the places that are hard to reach. Because they have met few people from the outside world, they don’t know about modern inventions. They have not learned ways of doing things from others.

For 25,000 years, groups of people have lived alone in the middle of Australia. One of these groups is the Arunta tribe (部落). They do not know how to farm and how to raise sheep or cattle.

The Aruntas spend most of their time searching for food and water. The men hunt animals with stone-tipped spears. The women and children look for roots, seeds and nuts. They use sticks to dig up the roots. Several Arunta families live together. They have no house. At night, they sleep around small fires.

Now other people are moving into the center of Australia. Soon the Aruntas will no longer be a Stone Age people.
