雅思写作范文：动物实验

　　Perhaps no subject in the moral community is as controversial as animal testing. Animals, many people believe, merit more humane treatment. When animal-based experiments have long been the centre of criticism, I am of the opinion that such experiments are essential to both the well-being of human beings and that of animals.

　　There is little doubt, first of all, that most of the animal-based experiments are conducted for the development of technology and to date, there is little chance of finding satisfying substitutions for animals, Animals are used mainly because they bear a close resemblance to humans, either in behaviour or in cell structure. They respond to external disturbances (such as electrical shock) nearly in the same manner as humans do. There is much evidence that most of what people know about themselves, including pain, stress, reproduction and nutrition, is based on findings of animal-based experiments. Animal testing proves one of the main approaches to predict the risk when drugs or other products are used on humans.

　　Another fact to support animal-based experiment is that animals are not the equivalent of humans, and can be used as resources for human purposes. Animals have no capacity to recognize the rights of other species. Nor will they take in consideration the interests of other species. It is possibly one of the main reasons why animals feed on each other. Humans, by comparison, use animal experimentations not only for their own interests but also for the interests of animals. For example, some medical discoveries can be used by veterinary surgeons to give medical care and treatment to sick animals.

　　Despite the justifications given for vivisection, researchers have the obligation to reduce animal testing and animal suffering. There is a growing recognition that animal tests are mostly done for commercial purposes and most of them are avoidable. For instance, the cosmetic industry has been exploiting animal experimentation simply for diversifying products and maximizing profits. The fewer cosmetic products people use, the fewer animals they have to slaughter. When scientists are empowered to carry out cruel experiments like vivisection, such powers should not be abused.

　　To summarize, one can subscribe to the notion that animals can be taken as resources intended for the benefit of humans, although meanwhile it is certain that suffering should be controlled to the minimum during experimentation.
