The answer to reading Angel's Wings! Urgent request!

A long time ago, there was a little boy who felt very inferior because he had two obvious scars on his back. These two wounds extended from his neck to his waist, and were covered with twisted muscles. Therefore, the little boy hated himself very much and was very afraid of changing clothes, especially during physical education classes. When the other students happily took off their sticky and uncomfortable clothes and changed into casual pants and vests, the little boy would only secretly hide in a corner, sticking his back against the wall and changing clothes as quickly as possible, afraid that others would find out that he had some terrible flaws. However, as time passed, the scar on his back was still discovered by his classmates. "So scary!" "You are a monster!" "Your back is so scary!" Innocent words from innocent students hurt the most. The little boy cried and ran out of the classroom. From then on, he did not dare to change his clothes in the classroom and never went to physical education class again. After this incident, the little boy's mother specially held his hand and went to find the class teacher. The little boy's class teacher was a very kind female teacher. She listened carefully to her mother's story about the little boy." This child was seriously ill when he was born. At that time, we were about to give up, but we couldn't bear to do so. How can we abandon such a cute little life so easily?" The mother's eyes turned red." So, my husband and I decided to save the child. Fortunately, there was a very skilled doctor who was willing to try to save the child's life through surgery. After several operations, he finally managed to save his life, but there are two clear scars on his back, which are proof that he fought for his life." The next day, during physical education class, the little boy timidly hid in a corner and took off his shirt. At this moment, all the children revealed surprised and disgusted voices. "There are two big worms on his back." The little boy's eyes couldn't help but become moist, and tears flowed down his face. At this moment, the teacher appeared unexpectedly. A few students immediately ran to the teacher and gestured at the boy's back. The teacher slowly walked toward the little boy and then showed a surprised expression. "Teacher has heard a story before. I really want to tell it to you now!" The students loved to listen to stories, so they quickly gathered around. The teacher pointed at the two obvious wounds on the boy's back and said vividly," This is a legend. Every child is transformed from an angel in the sky. When some angels turned into children, they quickly took off their wings. Some little angels moved slower and couldn't take off their wings in time! At this time, the child that the angel turned into will leave two scars on his back." "So these are the wings of an angel!" The students pointed at the little boy's back and exclaimed. "Yeah!" A mysterious smile appeared on the teacher's face. The little boy stood there in a daze. His originally teary eyes had stopped crying at this moment. Suddenly, a little girl said innocently,"Teacher, can we touch the little angel's wings?" "We have to ask the little angel if she's willing to do this." The teacher smiled and winked at the little boy. The little boy mustered up his courage and said shyly,"Okay!" The girl gently touched the scar on his back and shouted happily,"Ah, that's great!" I feel the wings of an angel!" "I want to touch the little angel's wings too!" All the children shouted desperately. Later, the little boy gradually grew up. He was deeply grateful to this teacher who had restored his confidence. In high school, he even participated in the city-wide swimming competition and won the second place. He bravely chose to swim because he believed that the two scars on his back were the " angel's wings " blessed by his teacher's love. He summarized the content of the article in one sentence.
