There was once a lonely girl who wanted love very much. One day she was walking in the forests, she found two dying birds. She took them home and put them in a small . She was happy to have two “friends”. She them with love and the birds grew strong. One day the girl happened to the door of the cage open. The larger and the of the two flew out of the cage. The girl was that it would fly away. She caught it quickly. She felt glad that she caught the bird before it could fly away. Suddenly she couldn’t a sound from the bird. When she opened her , the bird was already dead. Her killed the bird！Then she noticed bird jumping up and down inside the cage. She could feel great need for freedom. It wanted to fly into the clear, blue . So she lifted it from the cage and let it fly away . The bird circled once, twice, and three times. The girl watched as the bird flew. She didn’t care about the bird any more. She wanted it to be happy. Suddenly the bird flew closer and landed softly on her shoulder. It sang the song she had ever heard. The fastest way to lose love is to hold on it too tightly, and the best way to keep love is to give it wings(翅膀).
