Some Fun and Interesting Facts
　　Do you think what colour oranges are The common answer to this question is “Orange”. However, the first oranges from south east Asia were actually green. Up to now, oranges in warmer areas like Vietnam and Thailand still stay green when they are fully grown.
　　There was a man named John Chapman who planted thousands of apple trees. But the apples on those trees were much more bitter(苦的) than the ones you'd find in the supermarket today. John didn't expect his apples to be eaten whole, but rather made into hard apple cider(苹果酒).
　　Like most four legged animals, cats have five toes on the front paws(脚爪), but their back paws only have four toes. Scientists think the four toe back paws might help them run faster. Do you know any other fun facts about cats？
　　Walt Disney might have been the first to put gloves on his characters, as the star Mickey Mouse in 1929's The Opry House (《奥普里之屋》). Besides being easier to interest people，there's another reason why Disney did so. “We didn't want him to have mouse hands because he was supposed to be more human，” Disney once said.
