The note read，"Call Margaret at 555-6167．"As a car instructor （教员），I often got calls from people to repair their cars．I dialed．A voice answered，"I have something to tell you．"

"All right，"I answered，looking at the clock．I only had a few minutes before I went back to class．"Yesterday I was driving when my car started acting up （出故障）．It was late at night．I was so afraid to stop the car to the side of the rode，but finally my car just broke down．I sat there wondering what to do．"

I really needed to get back to class．"Would you like me to look at your car？"I asked．

"Let me finish．Suddenly，two young men came．I didn't know what they were going to do．I was so scared．"

"They asked me what happened and said they might be able to get the car running again．I sat in the car hoping that these men weren't doing something bad．A few minutes later，they started the car．It started right up!They told me the car would be fine but that I should get it checked out．"

"And you'd like me to look at it，right？"I asked．

"No，"the woman went on．"I was so thankful．I offered them money，but they wouldn't take it．Then they told me they were former （以前的） students of yours．"

"What？"I asked in surprise．"Who were they？"

"They didn't tell me．They just gave me your name and the school's name and made me call to thank you．I hope you know how thankful I am．"

I didn't know what to say．I always tried to teach students to be honest and other things about life-use what you know to help others．My students helped someone because of what I had taught them in my classroom．I had just got the greatest reward a teacher could ever get．
