Tina was a seventeen-year-old girl who always wore a bright smile. She suffered from a disease and had to use a walker most of the time. People didn't speak to her very often. Maybe it was because she looked1 and people didn't know how to come near to her. Tina usually broke the ice with people she met with a big “2.”
In one class, I gave the students an assignment (作业) to recite(背诵) a poem. I only made the assignment worth a very small part of their total grade since I knew most of my students would not do it anyway. In the class, one by one each student 3 to correctly recite the poem. Finally, angry and half joking, I said that the next student who 4 recite the poem had to do three push-up (俯卧撑). To my surprise Tina was next. She used her walker to move to the front of the class. 5 she recited, she made a mistake. Before I could say a word, she 6 her walker and started doing push-ups. I wanted to say, “Tina, I was just joking!” But she7 , continued the poem and she finished the rest perfectly.
When she finished, a student asked, “Tina, why did you do that? It's not an important assignment!” “Because I want to be like you guys! To be 8 .” Tina said.
Silence fell on the whole room when another student cried out, “Tina, we're not normal! We are teenagers! We get in 9 all the time.” “I know,” Tina said as a big 10 spread across her face. The rest of the students laughed, too.
Tina got only a few points that day, but she got the love and respect of her classmates. To her, that was worth a lot more than a grade.
