Reading 阅读关于驯化动物的文章，了解动物是如何被驯化的。 The story of domestication Long ago, dogs, sheep and cows used to be wild animals. How did they turn into pets and farm animals? Let’s find out! Dogs The story of domestication started somewhere in Asia, about 15,000 to 23,000 years ago. Back then, people moved across the land. They hunted large animals and often left meat on the ground. This attracted wolves, and they probably began following the hunters. Some people started catching baby wolves. They trained these young wolves to hunt with them. With every generation, people kept wolves with “friendly” genes. Over thousands of years, these pet wolves turned into dogs. Sheep Around 13,000 years ago, people in West Asia began to domesticate animals like sheep. Sheep are small and not very dangerous, and they move in big groups and follow their leader. This makes them easy to domesticate. They became an important source of meat. Later, the farmers also learnt how to make clothes from their wool. Cows People in West Asia started to domesticate aurochs—a kind of wild ox—sometime after 8000 BCE. Aurochs are now extinct, but they used to live all over Europe and Asia. They provided people with milk and meat, and they were also good working animals. As with other animals, people chose to keep aurochs with “good” genes, and the animals slowly turned into the cows we see today. Over many thousands of years, pets and farm animals changed because of human efforts. The story of domestication still continues today. 1 Where can you read the article? a story book a science book a diary √ The article contains facts about how different wild animals were domesticated. 2 What is the article talking about? about 15,000—23,000 years ago somewhere in Asia with hunting/hunt around 13,000 years ago West Asia meat and wool sometime after 8000 BCE West Asia milk and meat good working animals 3 What makes sheep good farm animals?
