动物试验的争议雅思口语范文
动物试验的争议雅思口语范文Should experiments be conducted on animals for the benefit of human beings?Every day, thousands of people are saved from painful diseases and death by powerful medical drugs and treatments. This incredible gift of medicine would not be possible without animal testing. Despite these overwhelming benefits, however, some people are calling for animal testing to be banned because of alleged cruelty. This essay will examine arguments for and against animal testing.Those against the use of animal testing claim that itis inhumane to use animals in experiments. I disagree pletely. It would be much more inhumane to test new drugson children or adults. Even if it were possible, it would also take much longer to see potential effects, because of the length of time we live pared to laboratory animals such as rats or rabbits.Opponents of animal testing also claim that the results are not applicable to humans. This may be partly true. Some drugs have had to be withdrawn, despite testing. However,we simply do not have alternative methods of testing. Computer models are not advanced enough, and testing on plants is much less applicable to humans than tests on animals such as monkeys. Until we have a better system, we must use animal testing.A further point often raised against animal testing is that it is cruel. Some of the tests certainly seem painful, but the great majority of people on this pla eat meat or wear leather without any guilt. Where is their sympathy for animals? Furthermore, animals clearly do not feel the same way as humans, and scientists are careful to minimize stress in the animals, since this would damage their research.。

动物作用于医学实验你对此看英语作文English: Animal testing has long been a controversial topic in the field of medicine. While some argue that it is necessary for the advancement of medical research and the development of new treatments and cures, others believe that it is unethical to use animals in this way. Those in favor of animal testing argue that it is crucial for understanding the effects of new drugs and treatments, as well as for ensuring their safety before they are tested on humans. Without animal testing, they argue, many important medical advancements would not have been possible. However, opponents of animal testing argue that it is cruel and inhumane to subject animals to unnecessary suffering, especially when there are alternative methods available. They also point out that animals may not always be good models for human diseases and that there are ethical concerns about using living beings for experimentation. Despite these arguments, animal testing remains a common practice in the medical field, with regulations in place to ensure that it is done in a humane and ethical manner.中文翻译: 动物实验长久以来一直是医学领域的一个争论话题。
科学家用动物做药物研究的英文作文
科学家用动物做药物研究的英文作文Title: The Use of Animals in Drug Research by ScientistsIntroductionDrug development and research are integral parts of the healthcare industry. Scientists have been utilizing animals for decades to study the effectiveness and safety of potential treatments. This practice has been met with ethical concerns and debates, but it remains a crucial aspect of modern medical advancements. In this essay, we will explore the reasons behind scientists using animals in drug research and the ethical implications of this practice.Why do scientists use animals in drug research?Scientists use animals in drug research for several reasons:1. Similar biological responses: Animals have similar biological systems to humans, making them suitable models for studying how drugs may react in the human body. This allows scientists to predict potential side effects and efficacy of new drugs.2. Controlled experiments: Animals can be bred and raised in controlled environments, allowing scientists to manipulatevariables and closely monitor the effects of drugs. This controlled setting is essential for accurate data collection and analysis.3. Ethical considerations: While using animals in research raises ethical concerns, it is often seen as a necessary sacrifice to ensure the safety and effectiveness of new drugs for human use. Animal testing helps to prevent potential harm to humans during clinical trials.4. Regulatory requirements: Many regulatory bodies, including the FDA and EMA, require animal testing as part of the drug approval process. This ensures that new drugs meet safety and efficacy standards before being tested on humans.Ethical considerationsDespite the benefits of using animals in drug research, there are ethical considerations that must be taken into account:1. Animal welfare: Animals used in research may experience pain and suffering, which raises ethical concerns about their treatment. Scientists must adhere to strict guidelines to ensure that animals are treated humanely and their welfare is prioritized.2. Alternatives to animal testing: With advancements in technology, there are alternative methods to animal testing, such as cell cultures and computer modeling. These methods aremore humane and may provide more accurate results in some cases.3. Transparency and accountability: Scientists must be transparent about their use of animals in research and be held accountable for their actions. This includes reporting on the methods used and the welfare of the animals involved.ConclusionIn conclusion, the use of animals in drug research by scientists is a controversial practice that raises ethical considerations. While the benefits of using animals as models for human disease research are clear, it is essential to prioritize animal welfare and explore alternative methods where possible. Scientists must balance the need for accurate data with the ethical implications of using animals in research to ensure that new drugs are safe and effective for human use.。
英语作文用不用动物做实验
英语作文用不用动物做实验Should Animals be Used for Scientific Experiments?Animal testing has been a controversial issue for many years. While some people believe that animal testing is necessary for scientific research, others argue that it is cruel and inhumane. In my opinion, animal testing should not be used for scientific experiments.Firstly, animal testing is cruel and inhumane. Animals are often subjected to painful experiments that can cause physical and emotional suffering. For example, mice andrats are commonly used in experiments that involve force-feeding, drug injections, and other invasive procedures. These experiments can cause the animals to experience pain, stress, and even death. Moreover, animals are often kept in small cages and deprived of food and water, which can lead to further suffering.Secondly, animal testing is not always reliable.Animals are not the same as humans, and the results of experiments on animals may not be applicable to humans. For example, a drug that works on a mouse may not work on a human, or may have different side effects. This means that animal testing can be a waste of time and resources, and can lead to false conclusions.Thirdly, there are alternative methods of scientific research that do not involve animal testing. For example, computer modeling and cell cultures can be used to simulate the effects of drugs and other substances on human cells. These methods are more accurate and reliable than animal testing, and do not involve any harm to animals.In conclusion, animal testing should not be used for scientific experiments. It is cruel and inhumane, not always reliable, and there are alternative methods of scientific research that do not involve animal testing. As a society, we should strive to find more ethical and effective ways of advancing scientific knowledge without harming animals.。

2018-06-30: Task 2 (India)Some people think it is necessary to use animals for testing medicine which are intended for human, while others say animals should not be treated this way of use animals for testing a medicine.Discuss both your views and give your opinion.范文1：Since the existence of humanity, animals have been good companions to us. Some people hold the view that animal testing is an inevitable procedure for the sake of humans. In my part, animal experimentation should be banned as they have the same rights as human beings.The advocators claim that scientists should make a good use of animals, such as test medicines in order to help human beings to combat more deadly diseases. The supporters of this view believe that animals bear a resemblance to humans, such as cell structure, as a result, animal experimentation is still regarded as a reliable and feasible method. It is undeniable that in some case is cruel. For instance, mice are sometimes injected with cancer cell for the medical researches. But it would be more brutal to use humans themselves as the testing objects, because humans cannot take any risk to lose their lives. Some one might argue that animal test will break the biological balance. However, some animals like rabbits or rats can be bred quickly in laboratories. In other words, it has a large number of supplies in the laboratories. Therefore, the animals testing will not break the biological ecosystem.An alternative opinion is that animals have the equal rights as human beings. Treating them so brutally will leave a negative impression on our next generation. Over thousands of years, animals have been always considered as the best friends to us. It can often been seen on the news that the old who live alone and abandoned by their children, accompanied by their loyal dogs. This is something positive we need convey to our young generation rather than maltreating animals. The harvesting of bear bile for traditional medicine is an unbelievable evidence of maltreatment, which would exert a bad influence on children. If it is inevitable to use animals to do some tests, as there is no other alternative way to replace them in some circumstances, humans should take the responsibility to reduce the pain for those animals. We need treat animals as humane as possible.In conclusion, animals, human beings’ friends, should be treated as equal right as humans. Once we have no choice to sacrifice their interests, humanity should be considered as the least option for medical testing.范文2：Whether nor not it is absolutely crucial for people using animals to test some medicines has been a hotly debated issue. There are those who argue that testing somemedicines on animals is essential. Some others do not completely agree with this viewpoint. In this essay, these views will be discussed and my view will be also presented.With regard to people who believe that it is necessary to use animals for testing some medicines. With the social-economic development, there are a variety of strange diseases to be being done research and scientists have to perform their obligations to test some new medicine on animals before doctor take prescriptions for patients. It is likely to be a right solution because life and well-being of human must be respected and safe. Therefore, scientists should be allowed to continue using this measure in the long term.As for those who do not completely agree to use animals to test new medicines. Animals need protecting and behaving like human beings. Moreover, animals also have the right to live as well as to have other basic rights and testing on animals is a serious violation of humanity. In other words, this has been considered as a cruel action against animals.As far as I am concerned, using animals to meet requirements of doing experiment is acceptable. In some cases, if patients take new medicines without testing before that, some unexpected consequences may occur to patients. What is more, via these tests, scientists find out more breakthroughs to limit counter-productiveness of the medicines because these drawbacks can cause people’s health more seriously, event leading to the deaths.It seems to me that it is important to maintain and develop to use animals for testing some medicines because it is rewarding for patients. Obviously, negatives of this method are outweighed by much larger positives.。
