Can zoos ever be animal-friendly?

    The topic of our last class discussion was “How can zoos provide animals with a good life?” Everyone believed it was impossible for zoos to give animals a caring environment. Our teacher suggested that visiting a modern zoo might give us a new point of view.

    ____ In our discussion, many people said that zoos were full of smelly cages with unhappy animals living in. Cleveland Metroparks Zoo, however, was set in an attractive, open environment. Trees and flowers had been planted around the park. ____

    At school, some people accused(指责)zoos of exploiting(剥削)animals for money but at Cleveland Metroparks Zoo, as I see it, nothing could be further from the truth. ____

    Before I visited Cleveland Metroparks Zoo, I wasn't sure about the rights and wrongs of zoos. ____ I feel that, although zoos can't provide the freedom of the wild, they can be animal-friendly by giving animals a safe and caring environment. As long as they do this well, to my mind they make a good contribution(贡献)to animal health. They also play an important part in educating us about wildlife. ____

    On the bus back to school, we all agreed that what we liked most was the zoo's environment and we would recommend(推荐)it for next year's group.

A. It is difficult for the zoo to raise animals.

B. More and more animals enjoy their wild homes.

C. I think lots of my friends changed their minds, too.

D. Most of the money is used to improve conditions at the zoo.

E. I went to the zoo and was pleasantly surprised by what I found.

F. In my opinion, the animals, rather than seeming upset, were pleased.

G. It was difficult to say how a zoo could really make up for animals' loss of freedom.
