I sat down to read under an old tree in the park. I felt my life was   36  , because my whole world was dark.

A young   37   ran up to me, out of breath（氣喘吁吁）. He stood right before me with his head down and said   38  , “Look what I found!” In his hand was a flower, and what a poor sight! The flower was dry and   39 . I gave him a small smile and then turned my eyes away so that he could take his dry flower and go off to play.

  40 , he sat next to my side and placed the flower to his   41  and said in surprise, “It smells sweet and it’s beautiful, too. That’s   42  I picked it. Here, it’s for you.” The flower before me was dead. But I knew I must   43  it, or he might never leave. So I accepted(接受) the flower, and replied, “This is just what I   44 .” Just then, for the first time I noticed that the boy could not   45 －h(huán)e was blind.

Tears came down my face as I   46  him for picking the best one. “You’re welcome.” he smiled, and then ran off  to  47 . I sat there and wondered how he was able to learn about my pain.

I decided to see the beauty in life, and   50  every second of my life. And then I held that dry flower up to my nose and breathed in the smell of a beautiful rose.
