提纲
1。 科学使人类进步，生活得更美好。
2。 科学有时也会带来负面效应，如原子能毁掉一切。
3。 就科学与人类的关系谈谈你的观点。
Science enables human beings to progress rapidly and lead a better life。 For example， Edison＇s invention of the light bulb brought our gloomy life to the end and created a bright world for us。 Another case in point is Watt＇s discovery of the steam engine， which triggered the industrial revolution in the western countries， and later all over the world。
Meanwhile， sometimes science does have some side effects。 A good illustration of this is atomic energy， which can destroy human beings completdy when used in nuclear weapons。
Anyhow， it is men who develop science。 And science， in turn， will do us good in general。 As for its side effects， I believe human beings will be rational enough to avoid them or keep them under control。
