阅读理解。 Do you know about Dolly, a famous sheep? She was created by cloning more than ten years ago in Scotland. Cloning is famous throughout the world. It is an experiment to make an animal that is exactly like its parent. So far, scientists have cloned rabbits, sheep, cows, mice, pigs and some other animals.
