     One day a lonely girl found two weak birds while she was walking in the woods (树林). She took them

home and put them in a small cage. She fed them with love and the birds grew strong. Every morning they

greeted her with a beautiful song. The girl loved them very much and wanted their singing to last forever.

     One day the girl left the cage's door open. The larger and stronger of the two birds flew out of the cage.

The girl watched worriedly as it circled (盘旋) high above her. She was afraid that it would fly away and she

would never see it again. So when it flew close, she grasped (抓) at it wildly. She was very happy that she

held it tightly within her hand! Suddenly, she felt something had happened to the bird. She opened her hand

and was surprised to find the bird was dead. Her love for the bird killed it.

    She noticed the other bird jumping in the cage. She could feel that it wanted to be free. It hoped to fly into

the clear, blue sky. She lifted (举起) it from the cage and flew it into the air. The bird circled once, twice,

three times…

    When the bird was flying happily in the sky, she was so glad. Just then the bird flew closer and sat softly

on her shoulder. It sang the sweetest song she had ever heard.

    The fastest way to lose love is to hold it tight; the best way to keep love is to let it fly!
