Knowledge is a treasure, but pra

We all hope to have plenty knowledge,for it will bring happiness and success.But only waiting for knowledge,it never comes.Actually, practice is the key to get knowledge.

It is disturbing to think that a number of people think we can get knowledge that it needn't practice.This idea will destroy our society.In my opinion,practice could help me really know one concept.When I was eight years old,I was requested to  write an article of baseball.I had never seen it before,then I became anxiously.At that time,I saw my friends were playing baseball,my face was light up.I immediately participated in them and spent five hours with them. Of course,I learned how to play baseball and the history of baseball,I finished my  article perfectly.
