【简答题】
Do you know how to play a game called Musical Chairs"? It is easy to play and most people enjoy it. All you need are some chairs, some people and some ways of making music. You may use a piano or any other musical instrument if someone can play it. You may use a tape recorder. You can even use a radio. Put the chairs in a line. The chairs may be put in twos, back to back. A better way is to have the chairs in one row with each chair facing in the opposite direction to the chair next to it. The game is easy. When the music starts, the players walk around the chairs. Everyone goes in the same direction, of course, they should walk in time to the music. If the music is fast they should walk quickly. If the music is slow, they should walk slowly. The person playing music cannot see the people in the game. When the music stops, the players try to sit on the chairs. If a person cannot find a chair to sit on, he drops out. Then, before the music starts again, one chair must be taken away. When the music stops again, one more player will be out. At last, there will be two players and one chair. The one who sits on the chair when the music stops is the winner.
