Lions are big and strong animals. They have grey or yellow fur. Their teeth are very sharp. Lions are good at running and hunting other animals. They mainly live on grassland. They are meat-eating animals. They usually look lazy because they don’t move around often. Now there aren’t many lions in the wild. People sometimes hunt them for fun. And people keep changing grassland into grazing land. They are losing their living areas.
If everyone plays a role in the protection of wild life, we are sure man will be a good friend of animal rather than their enemy.Can you promise to recite this passage?Can you guess what the hidden treasure is ?千里之行,始于足下.

They live in the sea and eat small fish and other sea life. One interesting fact is whales can jump high out of water. Some kinds of whales are in danger because humans catch them for meat, fat, and oil, and use whale parts to make candles and soap. Whales are also in danger from water pollution. We should protect whales by making rules on whale protection and by not putting rubbish into the sea. I think people should learn more about whales.谢谢21世纪教育网（www.21cnjy.com) 中小学教育资源网站 有大把高质量资料？一线教师？一线教研员？
