Some People Think It Is Necessary to Use Animals for Testing Medicines Intended for Human Use.
1. 动物实验的合理性是一个极具争议的话题。 The rationality of animals experiment is one of the most debatable topics nowadays.
2. 有些人认为，用动物做医疗实验是很有必要的，目的是为人类所用；然而其他人认为此事很残忍。
There are some people who argue it is essential to test medicines by using animals for human use, while others claim that it is bloody to perform that.
3. 这两种观点各有利弊。
There are advantages and disadvantages for both of the arguments.

1. 用动物做医疗实验是很重要的一项医药研究方法。
Experiment on animals is an essential medicines research approach.
2. 人类可以获得大量的[临床]数据，因为这种实验更有效。
Human could obtain a great quantity of clinical data as the experiment seems to be more effective.
3. 比如说，医学家经常用小白鼠做实验，研究治疗癌症药物的有效性。Remedy
For example, medicines scientists always use mice to conduct experiments, researching medicine’s usefulness.
4. 如果让癌症病人尝试新药，风险很大，容易产生医疗事故。medical negligence
If cancer patients are allowed to try new medicines, risking significantly and easily causing/leading to medical negligence.
5. 进一步说，用白鼠做实验，可以降低实验成本，因为它们繁殖快，饲养方便。Multiply
Furthermore, testing on white mice may contribute to the decline of cost, as they multiply quickly as well as being raised conveniently.
6. 可见，用动物于医药研究可提高效率、降低风险和成本。
Generally, using animals to test medicines may significantly increase efficiency and reduce risks and costs.
