完形填空。 One day, when I was in high school, I saw a kid named Kyle from my class walking home from school with all his books, I thought to myself, ' 1 would anyone bring home all his books for the weekend? He must really be 2 .' As I was walking, I saw several kids running toward him. They ran at him, 3 all his books out of his arms and he fell down in the dirt. His glasses went 4 and landed in the grass. He looked up and I saw this terrible sadness in his eyes. My 5 went out to him. So, I ran over to him. 6 I handed him his glasses, he looked at me and said, 'Hey, thanks!' There was a big smile on his face. I helped him pick up his books, and asked him where he lived. As it 7 , he lived near me. We talked all the way home. I didn't see him before as he had gone to a private school. Over the next four years, Kyle and I became best friends.

On the graduation day, I could see that he was 11 . So, I patted him on the back and said, 'Hey, big guy, you'll be 12 !' He looked at me and smiled. He cleared his throat, and began. 'Graduation is a time to 13 those who helped you make it through those 14 years. Your parents, your teachers… but mostly your friends. I am here to tell all of you that being a friend to someone is the best 15 you can give him.' I just looked at my friend with 16 as he told the story of the first day we met. He had planned to 17 himself over the weekend and was carrying his books home. 'Thankfully, nothing happened. My friend 18 me from doing the unspeakable.'
