Good morning, dear teachers (and judges), do you know the most previous difference between animals and plants? It’s not because most plants end to be eaten by animalsthat makes them in the lower place of the biological chain, it’s just because they are even not aware of their death. It’s not because human beings can walk with two legs that make them master the initiative of changing the world, it’s just because the power of thinking.
Common people can tell the difference between beauty and ugliness to decide how to dress themselves and how to build inner beauty by thinking. Great scientists change the hardware of the world with their mind, which makes our life more comfortable. Great thinkers change inner world of us humans, which will build more and more civilization.
Therefore, everyone should follow the old saying, think twice before you do.
