Some people think animal experiments should be stopped because they are too cruel. Others think they are necessary for the development of sciences. Discuss both views and give your own opinion.

题目讲评:

果然又是老题换个形式之后再出,题目考前给同学讲解过的这类文章想素材当然用咱们思考素材四类方法当中的综合法,相加得出观点:动物实验应该继续,但是要尽可能减小动物的痛苦。相应的写四段,大正小负,当然还是小的放在前面写。还是那句话,考IELTS学术类写作想拿高分或者满分永远只要按照English academic writing的规则写英文八股文就成。

1 开头段;2 有一些动物实验确实cruel;3 但是一些领域的研究又不能缺少动物实验;4 综合,得出结论。创作全程使用IELTS作文cold storage冷处理+assembly line装配法,给自己规定从开始写25分钟内要贴上Google。

Animals were friends or foes of humanity at different times of the human history. In modern times, experiments upon animals have long been a breeding ground for spirited debate. Some animal activists argue that we should ban animal experiments altogether because subjecting animals to experimentation is unjustifiable on moral grounds. Yet some other people contend that the advancement of science necessitates animal testing. Personally, I believe both their views have merit and demerit.

Granted, empirical evidence suggests that many animal experiments are performed callously without any heed to the discomfort or pain that laboratory mammals endure. First and foremost, improper confinement of test animals such as locking them up in cramped cages or poor veterinary is inhumane .It can gravely disrupt natural biological functions of the test animal. Further, the effects of vaccination and vivisection conducted on live rodents, primates and other lab mammals can be gruesome and chilling. They may, in some cases, even constitute sheer torture of live animals.

However, from a more pragmatic perspective, evidence is mounting that animal experimentation is still largely a necessary evil and there is no practical alternative for it at this point. In the first place, it is manifest that drug experimentation on live mammals is far more effectual than experimentation on bacteria or on other lower species in testing drug safety. Drugs that have severe potential side effects on homo sapiens must be tested by pharmaceutical companies on live mammals first to ascertain their toxicity. In the second place, in space research, live animals are still the only viable alternative to humans in testing living creature reaction to outer-space experience on a flight not considered to be sufficiently safe for human astronauts. Lastly, lab research about the behavioral tendencies of chimpanzees, gorillas, orangutans and other members of the primate group is also necessary. It produces valuable outcomes consistently advancing anthropological and genetic studies.

To conclude, I concede that experiments upon animals may induce suffering to the test animals. However, I am convinced that there are no feasible alternatives to this methodology at the current stage of scientific development. On balance , I think that we should allow animals testing to be continued but at the same time use techniques such as analgesic, anesthetic and tranquilizing drugs to minimize the pain inflicted upon the test animal and augment the general welfare of these animals.
