Do you agree or disagree with the following statement ?A zoo has no useful purpose. Use specific reasons and examples to explain your answer.
Zoos are often controversial because many people believe they are necessary or even harmful .If properly managed, I feel that zoos have a lot of value. In fact, I believe zoos are useful in two main ways: educating the general public and advancing scientific research.
动物园经常引起争议，因为许多人认为它们是必要的，甚至是有害的。如果管理得当，我觉得动物园有很大的价值。事实上，我相信动物园在两个方面是有用的：教育大众和促进科学研究。
Zoos can be wonderfully educational places. They provide a safe, controlled environment to learn about a specific species. Children can feel safe exploring the world of the chimpanzee there, and adults can learn about and see types of birds they've never seen before . Unlike in the wild , there's no worry of being physically harmed by an animal.
动物园可以是非常有教育意义的地方。它们提供了一个安全、可控的环境来了解特定的物种。孩子们可以在那里安全地探索黑猩猩的世界，成年人可以了解和看到他们以前从未见过的鸟类。与野生动物不同，动物园不必担心受到动物的身体伤害。
Zoos are also important for the research opportunities they provide. Research is safer and easier to conduct than in the wild. Scientists can feel secure in the confined area of the Zoo. For example, while conducting a medical experiment in an open field ,scientists have to worry about both the animal they have to worked with, and also other animals nearby .In zoos, however ,they need only worry about the research subject.
动物园对它们提供的研究机会也很重要。研究比在野外更安全、更容易进行。科学家们可以在动物园的禁区里感到安全。例如，在野外进行医学实验时，科学家们既要担心必须与之合作的动物，也要担心附近的其他动物。然而，在动物园里，他们只需要担心研究对象就行了。
In the wilderness, animals are also much harder to track and monitor. Zoos make research less time-consuming and expensive. Long term follows-ups are easier too, since even with monitors, wild animals often are killed and disappear. In zoos, researchers can observe an animal's entire life span.
在野外，动物也很难被跟踪和监控。动物园可以减少研究的时间和费用。长期的跟踪也比较容易，因为即使有监视器，野生动物也经常被杀死和消失。在动物园里，研究人员可以观察动物的整个生命周期。
Overall , I feel that properly managed zoos provide excellent opportunities for education and research, and are therefore very useful .
总的来说，我觉得管理得当的动物园为教育和研究提供了极好的机会，因此非常有用
