A Years ago,many zoos kept all kinds of animals in small cages (笼子) .Small cages made it easy for people to see the animals,but a small cage is not a good place for an animal to live in.

Today,zoos keep animals in different kinds of cages. The cages are very big and open. They usually have plants and little lakes. The cages look like the animals' wild home. They make the animals feel as if they were at home in the wild.

Zoos help to protect all kinds of animals. They protect not only animals in the zoo but also animals in the wild. How do they do this? They teach people how animals live in the wild. Zoos also help people to protect the animals' wild home.
