　　Many years ago,lots of zoos kept many kinds of animals in small cages．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 a little lake．The cages look like the animals' habitats(栖息地)．

　　Zoos help to protect animals in the wild．How do they do this?Zoos teach people how animals live in the wild．Zoos want people to protect the animals' wild habitats．
