雅思大作文范文解析：该不该用动物做实验

## 题目 Nowadays animal experiments are widely used to develop new medicines and to test the safety of other products. Some people argue that these experiments should be banned because it is morally wrong to cause animals to suffer, while others are in favour of them because of their benefits to humanity. Discuss **both** views and give your own opinion. 题型：双边讨论 翻译：如今动物实验被广泛应用于研发新药物和测试其他产品安全性。有些人觉得这种动物实验应该被禁，因为实验会给动物带来痛苦，从道德上讲是错误的；其他人支持进行动物实验，因为这些实验会造福于人类。讨论这两种观点，并给出自己看法。 ## 写作结构 开头段：背景介绍 + 个人立场 主体段1：（阐述反方立场）理由 + 论证 主体段2：（阐述正方立场 + 个人观点）理由 + 论证 结尾段：重申立场 ## 范文分析 ### 开头段 交代背景：“医药产品会先用动物做实验以确保适合人类使用”，以及个人立场：“虽然做动物实验在道德上是错的，但鉴于医学发展我支持限量的动物实验。” 背景句：It is true that medicines and other products are routinely tested on animals before they are cleared for human use. 个人观点： While I tend towards the viewpoint that animal testing is morally wrong, I would have to support a limited amount of animal experimentation for the development of medicines. ### 主体段 1 （阐述反方立场）以老鼠实验验证药物作用为例，反对者认为所有生物应被尊重，人类无权给动物造成这种伤害，而且这种行为带来的利益不足以证明它造成伤害的合理性，所以科学家应使用其他研究方法。 主题句：On the one hand, there are clear ethical arguments against animal experimentation. 举例 + 递进解释：To use **a common example** of this practice, laboratory mice may be given an illness so that the effectiveness of a new drug can be measured. Opponents of such research argue that humans have no right to subject animals to this kind of trauma, and that the lives of all creatures should be respected. They believe that the benefits to humans do not justify the suffering caused, and that scientists should use alternative methods of research. ### 主体段 2 （阐述反方立场）以老鼠实验验证药物作用为例，反对者认为所有生物应被尊重，人类无权给动物造成这种伤害，而且这种行为带来的利益不足以证明它造成伤害的合理性，所以科学家应使用其他研究方法。 主题句：On the other hand, reliable alternatives to animal experimentation may not always be available. 举例 + 递进解释：Supporters of the use of animals in medical research believe that a certain amount of suffering on the part of mice or rats can be justified if human lives are saved. They argue that opponents of such research might feel differently if a member of their own families needed a medical treatment that had been developed through the use of animal experimentation. **Personally, I agree with** the banning of animal testing for non-medical products, **but I feel** that it may be a necessary evil where new drugs and medical procedures are concerned. ### 结尾段 重申立场 ”在同等效力的方法发明之前，不该禁止以医学研究为目的的动物实验“： In conclusion, it seems to me that it would be wrong to ban testing on animals for vital medical research until equally effective alternatives have been developed. ## 重点表达 be cleared for 通过，确保无误 tend towards 趋向于 a limited amount of 有限数量的 ethical argument 道德伦理争议 subject sb to sth 让某人遭受某事 justify sth 为某事辩解 alternative methods 其他方法 a necessary evil 必要之恶，无法避免的灾难 equally effective alternatives 同等效力的其他方案
