My mother used to ask me what was the most important part of the body. Through the years I would believe         I thought was the correct answer. When I was younger, I thought         was very important to us as humans, so I said, “My ears, Mommy”. She said, “No. Many people are       . But you keep thinking about it and I will ask you again soon,”
Several years passed         she asked me again. For I had often thought of the correct answer, so this time I told her, “Mommy, sight is very important to everybody, so it         be our eyes”. She looked at me and told me, “You are learning fast, but the answer is not correct because there are many people who are blind.”
Over the years, Mother asked me a couple more        and always her answer was, “No, but you are getting        every year, my child.” Then last year, my grandpa died. Everybody was crying when it was our         to say our final good-bye to Grandpa. Mom asked me, “Do you know the most important body part yet, my dear?”
I was         when she asked me this now. I always thought this was a        between her and me. She saw the puzzlement (疑惑)on my face and told me, “This question is very important. It          that you have really lived your life.” I saw her eyes well up with tears. She said, “My dear, the most important body part is your       ”. I asked, “Is it because it        your head?” She replied, “No, it is because a crying friend or loved one can rest his head on it. I only hope that you have enough friends that you will have a shoulder to cry       when you need it.” Then and there I knew the most important body part is not a selfish (自私的）one. It is sympathetic (同情）to the pain of       .
