The power of smile
A smile is as tiny as a sand,while it may show you a new world.
A smile is as infirm as a daisy,while it may lighten the whole garden for you.
A smile is as peanut as a little drop of springwater,while it may water your eyes and illume your life.
This is the power of smile,which enables us to embrace our beautiful life.
We were well fascinated with Audrey Hepburn’s elegance and nobleness,with the charming and simplehearted expressions in her eyes.
Gradually,you may surprisingly find that the most beauteous thing is the pure smile on her face.
We were broken-hearted by Princess Diana’s misfortune.
When the whole world burst into tears for the passing of england's rose,people memorized her graceful smile and moving face when she was offering warm help to penniless children.
She let us realize that the most affecting expression is smile.
The beuaty of smile doesn’t lie in a simple act from eyes and mouth.It depends on the sincere passion to the world.
Have you ever experienced sadness?When it seems that the sunlight is faint and everything is likely to have been covered with thick snow.You feel tired and languid,lack of strength.
Just then,you see a pair of genuine eyes and a warm smile.The frozen ghyll seems to be awake again.There is some newborn burgeons on the treetops again.You know,the spring is approaching.You start to imagine the animation in the mountains ,the bright color in the fields and the first breath of spring in the forests.
Finally,you smile,for the happy and gorgeous life.
You might also have gone through worries and predicaments.You are down and dispirited,just like standing in the boundless desert,and everything around you seems to be swallowed up by the sand and time.Just then,a friend places his hand on the shoulder of yours and gives you a comforting smile.All of a sudden,you spots a little green in the vast desert.In your pleasant surprise,you see an oasis!
Finally,you smile,thinking of the braveness and obstinacy of life.
Giving an encouraging smile,a considerate smile or a laudatory smile to others,they may respond with an equally nice expression,or there has already been a new hope in their heart.
How extrodinary is the power of smile?No one knows.
When the sun is shining,please smile to him,as he is giving you warm love.
When there is lightening,please smile to the sky,as he is snapping a photo for you.
Just smile!Use the most beautiful language in the world to gain a pair of wings for your soul to fly in our real life.
