一般现在时
Do you like tigers I think a tiger is one of the most favorite animals that people like to see in the zoos. But now there are only about 3,200 tigers in the world, and the amount of them is smaller and smaller. That is because many trees are cut down and the tigers have no place to live in. In order to protect them we must build many natural reserves. And we must stop people from hunting.

佳作欣赏
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 world. People sometimes hunt them for fun. And people keep changing grassland into grazing land. They are losing their living areas.
