     These two letters appeared in a newspaper. Both writers have their own ideas on zoos.
                                                                 Zoos Do a Good Job
    It is good to keep animals in zoos. I know a lot of people think it is wrong to keep animals in zoos.
 However, I believe that zoos have many good points.
    Firstly, zoos are places for people to see different animals from all over the world. Without the zoos,
 most people would never see a real bear or tiger.
       Secondly, zoos look after the animals very well. The animals are always given food and cleaned
 regularly (定期的). In the wild, it is not always possible for an animal to find food, so sometimes it goes
  hungry. But animals kept in zoos never go hungry.
     Thirdly, zoos protect the animals they look after. They offer them safe places to live in. In the wild,
 some kinds of animals are in danger of becoming extinct (灭绝的). But zoos give these animals a chance
 to live. Without zoos. There would be fewer kinds of animals in the world.

                                                                      Zoos are Unnatural
     In Maria's letter, she says that zoos are good for animals. I am afraid that zoos are not good for
 animals, they are only good for people.
      It is unnatural and unfair to keep wild animals in cages. Most animals are kept in cages that are too
 small for them. In the wild, these animals would travel freely In zoos. They can't do this. This is why the
 bears and tigers always look so sad.
        Most cages are not very clean, either. It is true that zoos give the animals food regularly, but this is
 not natural. Wild animals are used to looking for their own food. We should treat animals in the same
 way that we treat other people with respect.
       Would anyone be happy if you don't let them go outside his home? Would Maria like to have lots of
 people stand out side her flat looking at her? No, she wouldn't. And animals don't like it, either.
