雅思写作指导：范文汇总-Animal Testing
Topic：Animal testing may be necessary， but we need to be be mercifulEvery year， millions of animals undergo painful suffering or death as a
result of scientific research into the effects of drugs， food additives，
cosmetics and other chemical products. While most people think animal testing is
necessary， others are upset by what they see as needless suffering. This essay
looks at some of the positive and negative aspects of animal testing.
Many medical treatments and procedures have been developed from experiments
on animals. Since animals share many features with humans， scientists use
animals to test the safety and effectiveness of newly developed drugs before
pilot testing on small groups of patients. Medical teams practice new operating
techniques such as transplants on animals. Without animal testing， many
procedures or new drugs would be extremely unsafe.
However， many people are concerned that animals are suffering unnecessarily
and cruelly. They do not believe that every new drug needs to be tested on
animals， especially with the huge database of knowledge and modern computer
models. They also are worried that many animal tests are ineffective， pointing
out that any drugs have had to be withdrawn from the market despite extensive
testing. They particularly feel that animal testing should not be used for
non-essential products such as cosmetics， shampoos， soaps， and cleaning
products. Furthermore， some campaigners would like to see certain tests replaced
and more humane methods used.
We need to make sure that the millions of animals who are used for testing
new products are treated with the minimum of suffering. Although some animal
testing may be unavoidable at present， treating our fellow creatures as
mercifully as possible will demonstrate our humanity.
