多年前我在斯坦福医院做志愿者时,认识了一个叫利兹的小姑娘,她得了一种很罕见、很严重的疾病。她获救的唯一机会就是让她五岁的弟弟给她输血。他也患过同样的病,却奇迹般地活了下来,并且体内有了这种疾病的抗体。医生向她的弟弟解释了这个情况,问他是否愿意把血输给姐姐。我看见他犹豫了片刻,然后深深吸了一口气,说:“如果那样做能救利兹,我愿意。” When I was a volunteer at Stanford Hospital many years ago, I met a girl named Leeds and she had a very rare and serious disease. Her only chance of rescuing was to have her five-year-old brother give her a blood transfusion. He also suffered from the same disease, but miraculously survived, and the body has antibodies to this disease. The doctor explained the situation to her younger brother and asked if he was willing to lose the blood to her sister. I saw hesitating for a moment, and then took a deep breath and said: “If that would save Leeds, I would.”
