My mother used to ask me, “What is the most important part of the body?” When I was young, I thought   16   was very important to us, so I said, “My ears, Mommy.” She said, “No. Many people are deaf but still live a  17   life; keep thinking and I will ask you again.”
Several years   18  before she asked me again. This time I told her, “Mommy, sight is very important to everybody, so it must be our eyes.” She looked at me and told me, “You are  19   fast, but the answer is not correct. Many people are blind, but they still live happily.” Over the years, she asked me many times and always her answer was, “No. But you are getting   20   every year, my child.”
Then last year, my grandpa died. Everyone was crying. When it was our turn to  21   our final goodbye to him, my mother asked me, “Do you know the most important body part yet, my dear?” I was  22   when she asked me this. I always thought this was a game between her and me. I saw her eyes with tears. She said, “My dear, the most important body part is your shoulder (肩膀).” I asked, “Is it because it  23  up my head?”  She replied, “No. It is because it can hold the head of a friend or a relative (亲戚) when he or she  24 . Everybody needs a shoulder to cry on sometime in life, my dear. I only hope that you have enough love and friends, so you will  25  have a shoulder to cry on when you need it.” That was when I realized what the most important body part is.

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
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.   
【小题1】If ten people are playing musical chairs，you must begin with ________.
