    Today, roller skating (滑冰) is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the

idea of skating didn't exist. That changed because of a man named Joseph Merlin. Merlin's work was making

musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams.

People called him a dreamer.

    One day Merlin received an invitation to attend a fancy dress ball. He was very pleased and a little excited.

As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had

an idea. He thought he would get a lot of attention if he could skate into the room. 

    Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe.

These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party

on wheels while playing the violin.

    On the night of the party Merlin rolled into the room playing his violin. Everyone was astonished to see him.

There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he

ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot

Merlin's grand entrance for a long time!
