I found out one time that day a favor(帮助) for someone could get you into a lot of trouble.

  I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me  36  something, but I didn’t understand. So I leaned(斜靠) over her way and  37  that she was trying to ask me if I had an extra pen. She showed me that hers was out of  38  and would not write. I happened to have an extra one,   39  I took it out of my pocket and put it on the desk.

  Later, after the test papers had been  40  , the teacher asked me to stay in the room when all the other students were dismissed（离开）. As soon as we were  41  , she began to talk to me about what it meant to grow up; she mentioned how  42  it was to stand on your own two feet and be  43  for your own acts. For a long time, she talked about  44  and emphasized(强调) the fact that when people do something dishonest, they are really  45  themselves. She made me promise that I would think  46  about all the things she had said, and then she told me I could  47  . I walked out of the room  48  why she had chosen to talk to me about all those things.

I tried to  51  about the pen, but all she could say was that it seemed  52  to her that I hadn’t mentioned anything about the pen the day she talked to me right after the test.  53  I tried to explain that was just doing the girl a  54  by letting her use my pen, I’m sure she continued to  55  that I had cheated on the test.
