Section 2: Animal - Zoo
1. To what extent is the use of animals in scientific research acceptable? Should we use animals in scientific experiments? Animal 2.doc
- Most scientific research has to rely on the results of animal experiments. Other alternatives, such as computer modeling, that could replace animals are very limited. Some people think that using animals in scientific experiments is immoral and cruel.
- In my point of view, only animals can fulfill the requirements of scientific experiments in a real world. For example, some medical universities use dogs as a substitute to allow students to be trained in their surgical techniques. Most people understand that we cannot use humans in experiments because it may be harmful and dangerous for humans. In other laboratory experiments, scientist often use animals like rats, frogs and rabbits to observe the results because only these animals have a similar organs as humans. Therefore, we can not deny that animals contribute a lot to the development of science.
- Although it seems impossible to replace animals in scientific experiments, we should not give up on these matter. Furthermore, we should try our best to reduce the use of animals in scientific experiments. In addition, we should try to reduce pain and distress of the animals during the experiments. For example, we can anaesthetize them before doing any experiments.
- To summarize, we should put more effort into finding the better alternatives than using animals in experiments. In the mean time, we could improve our abilities to reduce the suffering of the animals in the experiments.

3. Some people think that human needs for farmland, housing, and industry are more important than saving land for endangered animals. Do you agree or disagree with this point of view? Why or why not? Use specific reasons and examples to support your answer. TOEFL45
Disagree:
- there is a delicate balance of nature. Of one small part is removed, it will effect all the other parts.
- Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies which migrate from CAnada to Mexico. Some of the breeding grounds of these butterflies was destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.
