　　参考答案

　　Animals have always been the sources of human food, clothes, medicine or other products since human civilization began. Some people, however, claim that human use of animals is no more necessary in modern time. Even as an animal lover, I am against this view myself.

　　On the one hand, animal meat, by providing necessary nutrition (protein , fat) and energy, is essential to human health. Living in this competitive modern world, our energy consumption doubles with the increasing living pressure. When we are exhausted after a long day`s work, a wonderful meal of steak or chicken may be the best way to revive our vigor.

　　On the other hand, for human survival, it is crucial to extract valuable substance from animals for medical purpose. Only certain animals can provide a cure for some fatal disease, say, cancer, and it is common sense that a man’s life is of more importance than that of an animal in extreme situations.

　　Exploiting animals for clothes, however, is unnecessary. It is extremely cruel to slaughter minks or seals to make fur coats. Fashion means torture for defenseless animals. In modern society, high-tech materials can replace fur to keep human warm in cold winter.

　　In spite of the fact that we have every reason to use animals for food and pills out of necessity, we should always keep in mind that no wild or endangered animals are to be harmed for human interest. As the most powerful creature on the earth, we should be grateful for the sacrifice of animals we herd.

　　关于动物类话题解决思路：

　　个人和政府如何应对环境问题，以及人类保护动物的重要性是解题核心。

　　在应对环境恶化的时候，政府比个人有更多优势，第一，有钱。政府可以给开发清洁能源的企业提供财政补贴(financial support)。第二，有权。政府可以制定法律(make environmental laws)来对破坏环境的行为进行惩罚。第三，有号召力。政府可以在中小学设立环境教育课程(environment-protection programs)，提供青少年保护环境的意识(increase children’s environmental awareness)。

　　保护动物的重要性：动物实验是否可行?支持动物实验的原因：1. 医学技术(medical technologies)的发展依赖动物实验，比如新药物的研发需要动物实验来确保药物的安全性(safety)。2. 人类现有生物技术(bio-technology)尚无法找到动物的替代品(substitutes)来进行科学研究和实验。不支持动物实验的原因除了太残忍(merciless)，我们不能剥夺动物的生存权(the right of survival)之外，还有：1. 动物实验成果是在实验室环境下完成的，没有人能确保这些成果同样可以适用于人类身上。2. 动物实验容易让一些私人企业为了牟利，通过非法途径获得动物，其中包括野生动物，甚至稀有物种。
