first draft -Introduction

 Will you marry me? You are my best freind. All the words and sentences we speak everyday and everytime, all the words that we writes on the papers, all the sayings we hear everywhere is natural things for us. We take for granted our language ability and usually do not think about it deeply. If there is no language in our life, people may be equivalent with robots: can not understand common sense, can not express feelings, can not read books, may be no books, no beautiful lyrics, difficult in communicaiton. This human's wonderful ability, it is wonderous how people cook their language taht is totally important part of human life. Think of when you are a baby, especially when you could speak language and understand it. Most of people may can not remember then and forgot how they became genius of language. I have a cousin who is three years old. One day my sister was playing with her and she, a little baby, said to my sister "So what?". All family in that place was shocked and my sister asked a baby with surprising "Where did you learn that?' then she replied "From kindergarden." Seeing this, we can know babies influenced by the environment in their language learning. Babies leran language by repetitive practice, not by innate ability.
