今日话题：Should animal testing be legalized?

解题方案：观点+举例（实验研究报告）

Should animal testing be legalized?

Andy: Nope, definitely.

Why should it be banned?

Andy: ‘cause animal tests do not reliably predict results in human beings（无法可靠地在人体预测结果）.

Can you give me an example?

Andy: Well, for example, 94% of drugs that had passed animal tests failed in human clinical trials（临床试验）. According to neurologist （神经科医生）Aysha Akhtar, over 100 stroke drugs（治疗中风的药物） that were effective when tested on animals have failed in humans, and over 85 HIV vaccines（HIV疫苗） failed in humans after working well in primates（灵长类动物）like monkeys and chimpanzees(猩猩）. 

Do you have another reason?

Andy: Drugs that pass animal tests are not necessarily safe. 

What’s the example?

Andy: In 1950s, sleeping pill（安眠药）, thalidomide, caused 10,000 babies to be born with severe deformities（严重畸形）, but the drug had been tested on pregnant animal like guinea pigs（豚鼠）, cats, and hamsters （仓鼠）prior to its commercial release（在商业广告发布之前）.  Also, the arthritis（关节炎） drug Vioxx proved to have protective effect（保护作用） on the hearts of mice（老鼠的心脏️）, yet it ended up causing more than 27,000 heart attacks （心脏病突发）and sudden cardiac deaths（突发心脏病死亡）. 

示例答案

Nope, definitely, ‘cause animal tests do not reliably predict results in human beings. Well, for example, 94% of drugs that had passed animal tests failed in human clinical trials. According to neurologist Aysha Akhtar, over 100 stroke drugs that were effective when tested on animals have failed in humans, and over 85 HIV vaccines failed in humans after working well in primates like monkeys and chimpanzees. 

Also, drugs that pass animal tests are not necessarily safe. In 1950s, sleeping pill, thalidomide, caused 10,000 babies to be born with severe deformities, but the drug had been tested on pregnant animal like guinea pigs, cats, and hamsters prior to its commercial release.  Also, the arthritis drug Vioxx proved to have protective effect on the hearts of mice, yet it ended up causing more than 27,000 heart attacks and sudden cardiac deaths.
