Saying goodbye to childhood,we step into another important time in the pace of young,facing new situations,dealing with different problems…… 　　everyone has his ownunderstanding of young,it is a period of time of beauty and wonders,only after you have 　　experienced the sour ,sweet ,bitter and salty can you really become a person of significance.thre time of young is limitted,it may pass by without your attention,and when you discover what has happened ,it is always too late.grasping the young well means a better time is waiting for you in the near future,or the situation may be opposite . 　　having a view on these great men in the history of hunmanbeing,they all made full use of their youth time ,to do things that are useful to society,to the whole mankind,and as a cosquence ,they are remembered by later 　　generations,admired by everyone.so do something in the time of young,although you may not get achievements as these greatmen did ,though not for the whole word,just for youeself,for those around! 　　the young is just like blooming flowers,they are so beautiful when blooming,they make people feel happy,but with time passing by,after they withers ,moet people think they are ugly.and so it is the same with young,we are enthusiastic when we are young,then we may lose our passion when getting older and older.so we must treasure it ,don't let the limitted time pass by ,leaving nothing of significance.
