     Excuses!  Excuses !

     Harry was often late for school, and when the teacher asked him why he was late

he always had an excuse. " My alarm clock didn't go off,"  he said one morning. "The bus broke down, "he told her another morning. Usually he just didn't want to get out

of bed!

     When he didn't hand in his homework he had an excuse for this as well. "The dog ate it,"was one reason that he had forgotten to do it, or left it until he was too tired. He always thought of someone or something to blame for his mistakes.

     "Why are your grades so bad, Harry?" his mother asked him one afternoon.

      "It's not my fault (错误) , Mom,"Harry replied.

     "My teacher isn't very good. "

     "Then I will phone the school and talk to your headmaster, " his mother said.

      "No , no. " Harry said quickly. "That won't help. He doesn't like me."

      "Then we'll have to send you to a different school, " his father said, " You won't

see your friends anymore but your grades are more important. "

      Harry thought about this for a minute. He didn't want to change schools. Then he said, "I probably could try harder to get to school on time. "

      "That would help, " his  mother replied. "But what  about your homework?"

        "Well, "he said. "I suppose l could work harder to keep up with my homework

as well. I think I'll  go and do today's homework right now. "

     When Harry left the room, his father said to his mother , " That  wasn't  too  

difficult , was  it? "
