I have met many interesting people. I'll tell you about one of them. Many years ago, when I worked 16 a volunteer at Stanford Hospital, I got to know a little girl 17 (name) Liza who was suffering from a rare and serious disease. Her only chance of _18 (recover) appeared to be a blood transfusion from 19 five-year-old brother, 20_ had survived the same disease and developed the antibodies needed to bat the illness. The doctor explained the situation to her little brother, and asked the boy 21 he would be willing to give his blood to his sister. I saw him hesitate for a moment before taking a deep breath and saying, Yes, I'll do it if it will save Liza.
As the transfusion progressed, he lay in a bed next to his sister, 22 (smile). 23_ then his face grew pale and his smile faded. He looked at the doctor and asked with 24 trembling voice, Will I start to die right away?
Being young, the boy had misunderstood the doctor. He thought he was going to have to give her 25_ his blood.
