In American schools there is something called Homecoming Day. Many high schools and colleges with a football team have a homecoming game. This can be the most important thing of the year except graduation of commencement day(毕业典礼日).Students plan Homecoming Day for many weeks in advance(预先).

    Several days before Homecoming，students start to decorate the school. There are signs to wish luck to the team，and many other signs to welcome all the graduates. Many people still come to Homecoming twenty or thirty years after their graduation.

    The members of school clubs build booths(摊位)and sell lemonade，apples and sandwiches. Some clubs help to welcome the visitors.

    During the day people like to look for teachers that they remember from long ago. Often they see old friends and they talk together about those happy years in school.

    Everyone soon comes to watch the football game. When the game is half over，the band comes onto the field and plays school songs. Another important moment is when the Homecoming Queen or King appears. All the students vote a most popular student as Homecoming Queen or King. It is a great honor(荣誉)to be chosen.

    Homecoming is a happy day，but it is not perfect unless the football team wins the game. Even if the team loses，the students still enjoy Homecoming Day. Some stay at the school to dance，and others go to a party. For everyone it is a day worth remembering.

    Today, roller-skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, no one had any ideas of roller-skating. That changed because of a man named Joseph Merlin. He liked to make things and play the violin in his free time. He was a man of ideas and dreams. People called him a dreamer.

    One day Merlin was invited to a party. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make an amazing entrance at the party. He had an idea. He thought everyone at the party would show much interest if he could skate into the room. He 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 very surprised 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 mirror that was hanging on the wall. The mirror fell down, breaking into pieces. Merlin's idea was so good that nobody forgot his special entrance for a long time. But could he find out a way to stop his roller skates?
