William Shakespeare said，“The web of our life is of a mingled yarn (紗線)，good and ill together.”The above brief review of the application of only one part of human activities—science seems to prove what Shakespeare said.But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war? 【個性思考】 Does scientific development have great effect on your life? Give some examples. My view: 人生啟迪 　　隨著社會的發(fā)展，人們越來越重視人與自然的問題，越來越強調(diào)人與自然和諧發(fā)展。其中，人與動物的關系問題也越來越引起人們的重視。我們應該對動物采取什么態(tài)度呢？ 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（噩夢）. However，to get a fuller view of such a controversial issue（矛盾的問題），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（適者生存）. 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（和諧） that existing in the nature world. 111
