There is a black box in Lisa's house that has been locked for a long time. Lisa has always been curious about what was inside the box.

  One day when she opened the box, she saw a golden light flashing. Then the light slowly disappeared. Lisa found a magic wand which looked like the one in the "Harry Potter" movies. She examined the box carefully and saw a book. She took out the book and started reading it hastily. Then Lisa waved the magic wand and uttered some words from the book. Then the magic wand flashed and her messy room became tidy in an instant. Lisa was delighted and amazed.

Then Lisa thought that since she had a magic wand, she wanted to put it to more meaningful use. She left her home and started her journey. While she was walking along the riverside, she saw black smoke emerging from a factory chimney, polluting the clear blue sky. What an eyesore.

 Suddenly Lisa had an idea. She waved the magic wand and uttered a spell. In a second, a storm came and blew away the smoke. Then the air was clean and fresh again! People who were choked by the smoke could breathe the air without fear.

No one except for Lisa knew what really brought about the change. Lisa joyously went home. After going home, she put the magic wand and the book into the box and locked the box. She wanted to keep the secret and continue to do more good with her magic wand.
