　　 Years ago, many zoos kept all kinds of animals in small cages (笼子). Small cages made it e 51　 for people to see the animals, but a small cage is not a good place for an animal to l　 52　 in.

　　 Today zoos keep animals in d　 53 　kinds of cages. The cages are very b　 54 　and open. They usually have plants and a little lake. The c　 55　 　look like the animals’ wild habitats (栖息地).

　　 Zoos help to p　 56 　all kinds of animals. They protect animals in the zoo and they protect animals in the wild. How do they do this? Zoos show people h　 57 　animals live in the wild.
