    Musical Chairs
    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 way 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 row.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 round 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 play-ers 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.

    The chairs should be put______.
    A: with the desks
    B: before the winner
    C: all over the room
    D: in a line

    答案：D
    解析：
    因为在第四段有这样一句If a person cannot find a chair to sit on , he drops out.那么肯定是椅子比人数少，这样才会有人没地方坐，故选A。

    第二段的 Put the chairs in a row就是“把椅子排成一排”之意。故选D。


    由第三段中的句子When the music starts, the players walk round the chairs．故选C。


    本题可用排除法，由第一段第二句It is easy to play,A项正确；由最后一句The one who sits on the chair when the music stops is the winner. C项正确；由第四段的句子The person playing music cannot see the people in the game. D项正确。故选B。
