不懂化学的人都认为化学是有害的,对人类的生存形成了威胁,给人们的生活带来了灾难。其实,这样讲也并不全对。我们在承认化学带给人类危害的同时,我们更应该意识到化学带给我们生活的好处。没有化学,我们的衣服将只能是棉麻或者是动物的皮毛,而且没有化学物质动物的皮毛也不能得到处理,就相当于披了一张动物的皮。所以,我们应该意识到学习化学的重要性,化学课堂正式开设于初中阶段,这也是学生们初次正式接受化学的开始。学习好化学,对化学有一个正确的认识,让它成为服务于我们生活的一种工具。
People who do not understand chemistry think that chemistry is harmful, threatening the survival of human beings and bringing disasters to people’s lives. In fact, this is not all right. While acknowledging the dangers that chemistry brings to humanity, we should recognize the benefits that chemistry brings to our lives. Without chemistry, our clothes will only be cotton or animal skins, and without chemicals the animal’s fur can not be processed, which equates to the skin of an animal. Therefore, we should realize that the importance of learning chemistry, chemistry class was officially opened in junior high school, which is the first time students formally accepted the beginning of chemistry. Learn chemistry, have a correct understanding of chemistry, making it a service to our lives as a tool.
