The  day  without  friends is really  very  lonely,which  was once objected by  me .I used to  believe that the beautiful scenery can made   me cultivated ,while human beings can just make it worse .Now I still believe in myself ,but I can not deny that men is actually very important ,and no one can live away from others .On the other hand ,I always feel men too hard to understand absultly--how they can pollute the environment without thoughts.Seeing the blue and vast sky with sea,the lovely and wild  animals ,the green and fresh trees .....I wonder what they will feel,and how they can do anything to hurt it.I can not but feel lonely,is there people who love the nature heart and soul?
