At the meeting, other people were impressed by the kindness and natural beauty of his mother , but the little boy felt embarrassed(尴尬的) for his mom's looks ,and hid himself from everyone. However ,he heard the conversation between his mother and his teacher.
“How did you get the scar on your face?” the teacher asked.
The mother replied,“②When my son was a baby ,his room caught fire one day.Everyone was too afraid to get into the room, but I rushed into it. While I was running towards his bed ,a beam(横梁)fell down and I placed myself over him trying to protect him. I was knocked unconscious(失去知觉).③幸运的是,有人救了我们 。” She touched the burned side of her face . “But I have never regretted doing what I did ,”she added.
Having heard that, the little boy was so moved(受感动的) that he ran towards his mother with tears in his eyes. He hugged (拥抱)her and held her right hand tightly for the rest of the day.
