Some people think animal experiments should be stopped because they are toocruel. Others think they are necessary for the development of sciences. Discussboth 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(到北京来讲课了，但还是总收到长沙A类和G类同学们的来信，说拿到了好分数很高兴。我也很想念你们!)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Englishacademic writing的规则写英文八股文就成。

1 开头段(不少于4句);2 有一些动物实验确实cruel(五句);3 但是一些领域的研究又不能缺少动物实验(七句);4综合，得出结论(不少于3句)。创作全程使用IELTS作文cold storage冷处理+assemblyline装配法，给自己规定从开始写25分钟内要贴上Google。雅思考试费用

Animals were friends or foes of humanity at different times of the humanhistory. In modern times, experiments upon animals have long been a breedingground for spirited debate. Some animal activists argue that we should bananimal experiments altogether because subjecting animals to experimentation isunjustifiable on moral grounds. Yet some other people contend that theadvancement of science necessitates animal testing. Personally, I believe boththeir views have merit and demerit.

Granted, empirical evidence suggests that many animal experiments areperformed callously without any heed to the discomfort or pain that laboratorymammals endure. First and foremost, improper confinement of test animals such aslocking them up in cramped cages or poor veterinary is inhumane .It can gravelydisrupt natural biological functions of the test animal. Further, the effects ofvaccination and vivisection conducted on live rodents, primates and other labmammals can be gruesome and chilling. They may, in some cases, even constitutesheer torture of live animals.

However, from a more pragmatic perspective, evidence is mounting thatanimal experimentation is still largely a necessary evil and there is nopractical alternative for it at this point. In the first place, it is manifestthat drug experimentation on live mammals is far more effectual thanexperimentation on bacteria or on other lower species in testing drug safety.Drugs that have severe potential side effects on homo sapiens must be tested bypharmaceutical companies on live mammals first to ascertain their toxicity. Inthe second place, in space research, live animals are still the only viablealternative to humans in testing living creature reaction to outer-spaceexperience on a flight not considered to be sufficiently safe for humanastronauts. 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 geneticstudies.

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