for a long time, we have been pursuing the nature of human being, the essence of our life.   however, have you drawn a conclusion?  if not , then, let me give you some hint.   what has been neglected is usually the most valuable to a person.   just like the lyrics in that song: the eternal pursuit of my life.  what i have lost is just what i once gained.  ok, now let's embark on the main topic: language.  everyday, every moment, we enjoy ourselves through chatting with others, singing to ourselves and so on.  we just take it for granted to speak fluently a kind of language.   however, have you imagined that you have lost the ability of speaking.  then what about human beings who have been deprived of language?  it is incredible,right?  so just cherish our language, cherish our mother tongue.
