     I found out one time that doing a favor 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

whispered something, but I didn't understand. So I leaned over her way and found out that she was

trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I

happened to have an extra one, so I took it out of my pocket and put it on her desk.

     Later, after the test papers had been turned in, the teacher asked me to remain in the room when all

the other students were dismissed. As soon as we were alone she began to talk to me about what it

meant to grow up; she talked about how important it was to stand on your own two feet and be

responsible for your own acts. For a long time, she talked about honesty and emphasized the fact that

when people do something dishonest, they are really cheating themselves. She made me promise that I

would think seriously about all the things she had said, and then she told me I could leave. I walked out

of the room wondering why she had chosen to talk to me about all those things.

     Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk

to the girl next to me, it looked as if I was copying answers from the girl's test paper. I tried to explain

about the pen, but all she could say was that it seemed very strange to her that I hadn't talked of anything

about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing

the girl a favor by letting her use my pen, I am sure she continued to believe that I had cheated on the test.

1. Form the passage, we knew the story appeared_______.

A. in a teacher's office

B. in a language lab

C. in a school playground

D. in an exam room

2.What did the girl want me to do?

D. sit next to me.

3. When the teacher saw this, she asked the boy_____.

A. to stay behind after the exam

B. to stop to take the exam

C. to leave the room at once

D. to continue writing his paper

4. Why was I puzzled after my teacher talked to me at that time?

A. because I didn't understand what she said.

B. because I doubted if what she said was right.

C. because I didn't know she was joking with me.

D. because I doubted if she was complaining to me.

5. From the third paragraph we can infer that my attitude to my teacher is ______.
