In the past, I always thought that being a teacher was an easy job. But I changed my_21__when I became a part-time teacher.  About four years ago, Richard asked me   __22___I could help teach his students how to make a website about themselves.

I__23_because computer is what I do well and I didn't think teaching computer would be that__24__．

      But when I taught Richard's class, some of the students___25__ with their friends while I was explaining how to do something.  At first I just got angry with them, ____26__ Richard taught me to think why they were doing this.  He said that if he was   27   a lesson and the students were not listening, then he was angry with   28   for not making the lesson clear or interesting for them.  I told him that I didn't _29__ his idea.  He then asked me if I had ever 30___ the same thing.  That made me stop. Of course I had!

     If any of my past teachers are__31__this, I want to say sorry if I sometimes played around in the class__32__ you were teaching. I didn't think how that would make you feel. I promise I will do my best to be a good __33__ in the future. Please help us when we don't understand and most__34__don't be quick to be angry when we fail.__35__0f us are perfect but with your help we can be successful.
