     When I learned that my 71-year-old mother was playing Scrabble-a word game-against herself, I

knew I had to do something. My husband suggested we give her a computer to play against. I wasn't

sure my mother was ready for it After all, it had taken 15 years to persuade her to buy an electric cooker.

Even so, we packed up our old computer and delivered it to my parents' home. And so began my mother's

adventure in the world of computers.

     It also marked the beginning of an unusual teaching task for me. I've taught people of all ages, but I

never thought I would be teaching my mother how to do anything. She has been the one teaching me all

my life: to cook and sew: to enjoy the good times and put up with the bad. Now it was my turn to give

something back.

     It wasn't easy at the beginning. There was so much to explain and to introduce. Slowly but surely, my

mother caught on, making notes in a little notebook. After a few months of Scrabble and other games, I

decided it was time to introduce her to word processing (文字处理) This proved to be a bigger challenge

(挑战) to her, so I gave her some homework I asked her to write me a letter, using different letter types,

colors and spaces.

     "Are you this demanding with your kindergarten pupils?" she asked. 

     "No, of course not," I said. "They already know how to use a computer."

    My mother isn't the only one experiencing a fast personal growth period. Thanks to the computer, my

father has finally got over his phone allergy (过敏反应). For as long as I can remember, any time I called,

my mother would answer. Dad and I have had more phone conversations in the last two months than we've

had in the past 20 years.
