Could the use of animals in scientific experiments be justified?Well you may get totally different answers when you are in different positions．

　　Suppose you are a pet owner．When someone asks to take away your lovely dog for a scientific experiment, certainly you will cry out and claim that he or she is a devil．This is just the reaction we are expecting for it is love and concern for others that make human beings human, and this kind of love and care are not only existing among ourselves, but also between us and the nature．Can you imagine living in a world where people kill animals for any purpose they like?Can you expect people loving each other in that kind of world?It must be a nightmare(噩梦)．

　　However, to get a fuller view of such a controversial issue(矛盾的问题)，you should put yourself in another position．Scientific experiments using animals have contributed a lot in medical development．Thanks to that, cures for many kinds of disease, which have killed thousands of people in the past few decades, have been found now and many lives are saved．If you are one of those with that kind of disease, will you support using animals in scientific experiments that can save you or will you give up your hope of life?The majority chooses the former and it is reflecting(反映)the rule of the nature－the fittest survives(适者生存)．

　　Every creature on the earth is a gift．We should love and protect them while at the same time make good use of them, since it is not only for our own sake(原因)but also for the sake of the harmony(和谐)that existing in the nature world．

问题导入：随着社会的发展，人们越来越重视人与自然的问题，越来越强调人与自然和谐发展的问题。其中，人与动物的关系问题也越来越引起人们的重视。但科学试验又离不开动物，这的确是一个矛盾的问题。对于科学家用动物做试验，你的态度如何？

A student from a college：I think, it is OK．Without using animals in scientific experiment, how can we develop our society?How can we find some very important medicine to cure the fatal diseases?How can we develop our science?And how can we develop our society?It is very necessary to do experiment with animals．It is the rule of the nature．

A farmer：No, absolutely not．I love animals very much, I raise some pigs and some chickens．It is a waste of money to use animals in scientific experiment．Any use?I don’t think so．

A woman teacher from a city：I understand it but don’t support it．We should respect animals．They are also a part of the nature．They are equal to our human beings．We shouldn’t deprive(剥夺)their rights to survive．On the other hand, I think it is OK．For the development of our society, every one should make a contribution to our society, sometimes, we may give our lives to it, let alone animals．

An official：It is very necessary to use animals in our scientific experiments．It can promote the development of our society．Also it will make our country stronger and stronger if we find some advanced substances by experiments using animals．Compared with this, the lives of animals are trivial．
