GRE范文：如何看待动物实验的利弊

［参考范文］ 　　Every year, millions of animals undergo painful suffering or deathas a result of scientific research into the effects of drugs, foodadditives, cosmetics and other chemical products. While most peoplethink animal testing is necessary, others are upset by what they see asneedless suffering. This essay looks at some of the positive andnegative aspects of animal testing.
　　Many medical treatments and procedures have been developed fromexperiments on animals. Since animals share many features with humans,scientists use animals to test the safety and effectiveness of newlydeveloped drugs before pilot testing on small groups of patients.Medical teams practice new operating techniques such as transplants onanimals. Without animal testing, many procedures or new drugs would beextremely unsafe.
　　However, many people are concerned that animals are sufferingunnecessarily and cruelly. They do not believe that every new drugneeds to be tested on animals, especially with the huge database ofknowledge and modern computer models. They also are worried that manyanimal tests are ineffective, pointing out that any drugs have had tobe withdrawn from the market despite extensive testing. Theyparticularly feel that animal testing should not be used fornon-essential products such as cosmetics, shampoos, soaps, and cleaningproducts. Furthermore, some campaigners would like to see certain testsreplaced and more humane methods used.
　　We need to make sure that the millions of animals who are used fortesting new products are treated with the minimum of suffering.Although some animal testing may be unavoidable at present,  treatingour fellow creatures as mercifully as possible will demonstrate ourhumanity. （ 267 words ）
