One day, my English teacher asked me to help her save back-up（备份） copies of her work in the computer. I then realized I was able to know the grades of all of her students. I       her how to copy files（文件）from one disk to another and she thanked me.
A few days later, she asked me to help her again, because she        how to do it. When I showed it to her, some students in my class noticed   and began to talk among themselves       .Later that day, at lunch time, several of them came up to me.
"Hey, could you help us change our grades? We'll         for it."
I could not believe what I heard. I could get paid for something very       . "All right. I'll do it." The next day, my English teacher asked me to help him out again. When he was not paying attention, I changed their grades from Fs to As.
I soon became very popular among my friends. They began to treat me like God who could do        . Word spread quickly and I became very rich.
Everything was going fine         I was called into the headmaster's office. When I got there, both of my teacher and the headmaster were very angry. "I don't want to        what your teacher said, but I have to. She has too much evidence(证据)," the headmaster said. "Do you have anything to say for yourself?"
"No," I said finally. I didn't realize how        my behavior had been. I had disappointed my teacher and the headmaster. And there was no way      . I had to leave my school. That was a good lesson for me.
