2.根据短文内容,选择最佳答案。

    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 or commencement(颁授学位典礼) day. Students plan Homecoming Day for many weeks before the day.

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

    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 Homecoming Queen or King. It is a great honor 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. Some stay at the school to dance, and others go to a party. For everyone it is a day worth remembering.
