There're different kinds of animals in the zoo. We see the zoo keepers give them         to eat. They don't have to        food by themselves. They just eat, walk and        all day. So many of        may think that the animals there        happy and lucky. But most        them are sad. Why? They're        free.
Animals like elephants, monkeys and tigers        live freely and happily in        or mountains. Tigers,        example, run, jump, play with their children        catch small animals for food. But now they have to stay in        rooms in the zoo. Their life in the zoo is       different from their life in the forests.
Now many of us think        animals should go back to forests and mountains so that        earth will become better.
