A Wonderful Discovery. Sarah had a son of ten, who was called Jack.A Wonderful Discovery.
Sarah had a son of ten, who was called Jack. He did not like studying, but loved watching television. Sarah used to drive at school at half past four in the afternoon, bring Jack back home and give him some tea, but as soon as he got home, he always rushed to the television set and turned it on. “Haven’t you got any homework, Jack?” his mother always asked him as she began to make tea.
“Eh? Oh, yes, I have got a little,” he used to answer. “I’ll do it later when there’s nothing interesting on the television.”
At first Sarah had allowed Jack to watch television instead of starting his homework first, but soon she discovered that he never had a little homework – it was always a great deal- and that there was never a time when there was nothing interesting on television, so that after putting off doing his homework for a couple of hours, Jack was too tired to do his homework properly, if at all.
Sarah then decided to make him do it first. This was always a battle, and often when Jack obeyed his mother, he did his work quickly and carelessly as he wanted to finish it quickly and get back to his beloved television.
The result was the same as when he left his homework until last; bad work, which he was punished for the next day at school by getting low marks, either because his homework was full of mistakes, or because he did not know the work he was supposed to have prepared the night before.
One evening Jack’s science homework was about famous inventors like Thomas Edison, who made important discoveries and inventions in the field of electricity. When he had homework that consisted of learning facts, his mother began to test him when he finished, to try to make sure that he had really done the work properly and not left anything out, and this was what she did this time. She did not let him stop until she was sure that he knew what was in his book.
But this time, it was less of a battle than usual to make Jack sit down and go over what he had learnt carefully, because it had strong connection with television.
In class the next day, the teacher said to Jack,” What are some of the things that Thomas Edison did for science?”
“Well,” Jack answered happily, “first of all, if it were not for Edison, we’d all be watching television by candlelight.”
