On my first day of the sixth grade, I noticed one little girl called Amy on the school bus. “Don’t __26__ her,” Lauren said, who sat beside me. “Or they will make fun of you.”

Amy had many __27__ differences — lots of reasons for other kids to make fun of her. Her eyes weren’t straight. Her glasses were an inch thick. And she had really ugly teeth.

Every day __28__ we drove to and from school, kids would shout insults (侮辱) at Amy. “God, what a (n) __29__ face! Stop looking at me!” “Mr. Rolland (the driver)! Amy took off her __30__, and now her eyes are __31__ me! Make her put them back on!” For a while I shouted my share of insults, just so I’d fit in (合群). __32__, I didn’t want them to treat me the same way they treated Amy.

But while I was insulting her, my heart __33__ for the girl. I could see that the insults were making her look __34__, because she was so ashamed (羞愧) and alone. Then I wanted to __35__ her. I just didn’t know how to stop my schoolmates __36__ the night of our class roller-skating party.

Our whole class was there, including Amy. Amy didn’t know how to __37__, but I could see how much she wanted to __38__ like the rest of us. So I skated over to her and took her by the hand; we began the journey together around the skating rink (溜冰场). She just smiled, and sometimes she would laugh in __39__.

On the school bus the next morning there was much news about Amy and me __40__ together, __41__ nobody insulted her or me. And they didn’t do that for the rest of the year.

After graduation, I never __42__ Amy again. However, I never forget her and I’ve always __43__ if I changed her life for the better. But I know for sure she changed my __44__. After becoming her friend, I no longer tried to impress (给……留下印象) people by trying to __45__ like them. I became myself.
