Question

Long long ago, there were only a few thousand people in the world. These people moved from one place to another place over the land, hunting (打猎) animals for food.

No one knows how or when these people learned about growing food. But when they did, their lives first changed. They did not have to look for food any more. They could stay in one place and grow it.

People began to live near one another. And so the first village grew. Many people came to work in the villages. These villages grew very big. When machines appeared, life in the villages changed again. Factories were built. More and more people lived near the factories. The cities grew very big.

Today some people are moving back to small towns. Can you tell why?
