# 正文 75｜动物实验：按用途限定立场

## 本节题目

> 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.

### 参考回答

Animal testing has long been a common practice in medical research and product safety evaluations. While some argue that it is ethically unjustifiable and should be banned due to the suffering it causes to animals, others contend that the benefits to humanity outweigh the moral concerns. In this essay, I will discuss both perspectives and provide my own opinion on the issue.

On one hand, opponents of animal testing raise strong ethical arguments. The practice involves subjecting animals, such as laboratory mice, to painful procedures in order to test the effectiveness or safety of new drugs or products. Critics argue that animals, like humans, are sentient beings, and subjecting them to unnecessary suffering is morally wrong. They believe that humans do not have the right to inflict harm on animals for the sake of experimentation and that alternative methods of research, such as in-vitro testing or computer simulations, should be prioritized instead. In their view, the moral cost of animal testing is too high, regardless of the potential benefits to humans.

On the other hand, proponents of animal testing argue that it remains an essential tool for medical advancement. They contend that while animal experimentation is not ideal, it is necessary to ensure the safety and efficacy of new drugs and medical treatments. Given the complexity of human biology, alternatives like computer models are not always reliable or effective. In life-or-death situations, supporters claim, the suffering of a few animals can be justified if it leads to medical breakthroughs that save countless human lives. They also argue that those who oppose animal testing might change their views if a loved one’s life were saved by a treatment developed through animal research.

Personally, I believe that animal testing should be banned for non-medical products, where alternatives are available. However, when it comes to life-saving medical research, I think that animal testing may be a necessary evil, provided it is done with strict ethical guidelines to minimize animal suffering. In the future, as technology advances, I hope that more reliable alternatives will emerge, making animal testing obsolete.

In conclusion, while I understand the moral objections to animal testing, I believe that it should be allowed under controlled circumstances for essential medical research, until more effective alternatives are developed.

### 中文理解

动物实验长期以来一直是医学研究和产品安全评估中的常见做法。有人认为，这种做法让动物遭受痛苦，在伦理上无法成立，应该禁止；也有人认为，它为人类带来的好处超过了道德上的顾虑。下面我将讨论双方的看法，并说明自己的观点。

一方面，反对动物实验的人提出了有力的伦理理由。这种做法为了检验新药或产品的有效性与安全性，会让实验鼠等动物接受可能带来痛苦的操作。反对者认为，动物和人类一样能够感受痛苦，让它们承受不必要的伤害在道德上是不对的。他们认为，人类没有权利为了实验而伤害动物，应当优先采用体外实验或计算机模拟等替代研究方法。在他们看来，不管动物实验可能给人类带来什么好处，它付出的道德代价都太高。

另一方面，支持者认为，动物实验仍是推动医学进步的重要工具。他们承认动物实验并不理想，但认为，要确保新药和医疗手段的安全性与有效性，它仍有必要。人体生理十分复杂，因此计算机模型等替代方法并不总是可靠或有效。支持者认为，在生死攸关的情况下，如果少量动物承受的痛苦能够促成医学突破、挽救许多人的生命，这样的代价就有理由被接受。他们还认为，如果反对者的亲人因一种通过动物研究开发的治疗方法而得救，反对者可能会改变立场。

就我个人而言，如果已有替代方法，非医疗产品的动物实验就应该禁止。但对于能够挽救生命的医学研究，我认为动物实验可能仍是不得不接受的做法，前提是严格遵守伦理规范，尽量减少动物的痛苦。随着技术进步，我希望未来会出现更可靠的替代方法，使动物实验不再有必要。

总之，我理解人们对动物实验的道德反对，但在更有效的替代方法出现之前，我认为可以在严格控制的条件下，允许必要医学研究中的动物实验。

### 逻辑链

* 引言｜交代伦理与医学效益的争议：动物受苦的道德问题 ↔ 对人类的医学收益 → 双方都要解释。

* 主体一｜说明反对者的伦理理由：动物能感受痛苦 → 不应承受不必要伤害 → 优先探索替代研究。

* 主体二｜说明支持者的医学理由：需要检验治疗安全有效 → 替代方法有限 → 挽救生命的收益被认为能支持例外。

* 个人判断｜按用途与条件区分：非医疗用途且有替代 → 禁止；必要医学研究 → 严格伦理限制；等待更可靠替代方法。

* 结论｜重申有条件的例外：理解伦理反对 → 只在控制条件下保留必要医学研究，不突然扩大许可范围。

### 本题词伙

* **medical research**：医学研究；conduct / fund medical research，注意 research 通常不可数。

* **inflict harm**：造成伤害；inflict harm on animals，表达伤害的对象。

* **medical breakthroughs**：医学突破；lead to medical breakthroughs，不用把 breakthrough 当一般改进。

* **ethical guidelines**：伦理规范；follow / apply ethical guidelines，说明约束条件。

* **alternative methods**：替代方法；develop alternative methods of research，交代替代什么。

### 替换与拓展

* **minimise suffering**：尽量减少痛苦

  Research rules should aim to minimise suffering.

* **assess potential risks**：评估潜在风险

  New testing methods need to assess potential risks.

* **place strict limits on**：对……施加严格限制

  Authorities could place strict limits on unnecessary testing.

### 句型语法

* **用 provided 限定允许的条件**：provided 相当于 only if；it is done 是被动，强调实验必须怎样进行。写有条件支持时，条件应实际约束主张。

  原句：However, when it comes to life-saving medical research, I think that animal testing may be a necessary evil, provided it is done with strict ethical guidelines to minimize animal suffering.

  结构：… may be necessary, provided + 从句.

  迁移：Public funding may be useful, provided it is allocated transparently.

  公共资助可能有用，前提是资金分配公开透明。

* **用 where 限定适用情境**：这里 where 不仅指地点，也指存在替代方法的情况。避免把针对某种用途的判断扩大到全部实验。

  原句：Personally, I believe that animal testing should be banned for non-medical products, where alternatives are available.

  结构：… should…, where + 适用情况.

  迁移：Online services should be offered where travel is difficult.

  在出行不便的情况下，应该提供线上服务。

* **用假设情境说明立场可能变化**：if 从句的 were saved 表示假设中的被救情境，并非报道过去事件；主句 might change 保留可能性。不要把假设例子写成已经发生的研究事实。

  原句：They also argue that those who oppose animal testing might change their views if a loved one’s life were saved by a treatment developed through animal research.

  结构：… might change… if + 主语 + were + 过去分词.

  迁移：Residents might support a new service if their daily journeys were made easier.

  如果日常出行变得更方便，居民可能会支持一项新服务。

## 选择与组织 · 为什么这样写

### 把题目要求拆清楚

讨论伦理反对与医疗支持；个人判断可区分用途和替代方法。

### 怎样组织段落

动物痛苦与替代方法→必要医疗研究→非医疗与医疗不同条件。

### 为什么这样选择

条件立场需要明确界线：必要性、可替代性与伦理控制，不能只写视情况而定。

## 语言与精度 · 本节重点

not all experiments are necessary；avoid unsupported medical claims or invented studies。

## 最后练一练 · 先组织，再写

读熟后，可以先遮住参考，回忆本节最有用的两三句。想动笔时再打开下方写作台，不需要首次学习就完成全文。

### 定点练习

把“It depends.”写成可理解的判断。

::: details 写完后看一种参考处理

> I would oppose non-essential testing where reliable alternatives exist, while allowing necessary medical research under strict ethical controls.

检查它修正了什么意义或关系。可以使用不同措辞，但信息需要准确。

### 换题使用

**本站自编迁移题**

自编题：Should animals be used for entertainment and conservation programmes? 按目的区分，不复制医疗实验理由。

先试一段，再视需要写全文。将新内容写在写作台的“迁移”中；原稿留在“初稿”，修订另存到“修改”。图表题需要重新识别特征，书信与议论文需要重新回应任务。

::: details 打开写作台 · 短练、全文与复盘

全文练习至少250词，约40分钟；本节短练可以先写一个主体段。

**留一个复盘**：我能回忆哪组表达？换了内容后，哪一句还不熟？下一次先检查这个问题。
