The Fitting-in of Suzy Khan
The first time I saw Suzy Khan, I knew I had to help her. She was really small for her age of 12. The boy in my class often          about her and laughed their heads off. She would open a book, pretending to read, with tears dropping on the open page.
All I knew was that she was an orphan (孤儿) from Africa. She had just been adopted by a family in town who           that the best way for her to learn American ways of life was to be with american kids. I looked down at this           girl and promised myself that somehow I would help her.
But how could I help her            in with us? There had to be a           .
One day, when I went into the classroom, I saw that Suzy had            her geography book to a picture of a train, and in her notebook, she had made a(n)           copy.
I was surprised and thought that she could do something in the coming          show. So, I took her to see the art teacher, Miss Parker, and showed her what Suzy had          . “why, it’s wonderful,” said Miss Parker, who then showed us a poster she had painted          the talent show. “I need more of these, but I just don’t have enough          . Could you help me, Suzy?”
On the day of the talent show, Suzy’s             were everywhere ---- all over the hall and all over the school, each one different.
“And finally,” said Mr Brown, the schoolmaster, at the end of the show, “we have a (n) award. I’m sure you’ve all noticed the wonderful posters.” Everyone nodded. “One of our own students            them.”
I could hear everyone whispering. “Who in our school could draw          well?”
Mr. Brown waited a while before saying, “           this student worked so hard on the posters, she deserves a             ,too. Our mystery(神秘) artist is our new student ---- Suzy Khan!”
Mr. Brown thanked her for all the wonderful posters and gave her a professional artist’s set. “Thank you,” she cried.
I            , at that time when I was looking at her excited face, she’d probably never          anything in her whole life.
Everyone started to            their hands. Suzy Khan gave them a shy smile and the applause was defening. I knew then Suzy was going to ne all right.
