　　There is a zoo in our city. My parents often take me there on holidays. I like animals. I have a lot of toy animals in my room. In the zoo I can see tigers, elephants, monkeys, pandas, bears, snakes and marry other animals. Some animals are friendly, but some are not. Tigers, bears and some snakes are dangerous. That is why they have to stay in cages. But I do not think it is good for animals to stay in cages. They should be free. The animals in cages cannot be happy.

　　Tigers usually live in forests and mountains. They can run very fast. They catch and eat small animals like rabbits and deer, but now they live in small rooms. They have nothing to do every day. So they walk round and round in the cages, and they want to get out. When they are tired, they sleep. I feel sorry for them.

　　I think the most interesting animal in the zoo is the dolphin. I like watching them swim and jump. They swim fast and they jump very high. They can play with a ball. They can stand up and “walk” on water! They are very friendly to people. If you fall into the water and can't swim, they may come up to help you.
