2、
A little British boy was looking at a teakettle above fire.
The water within it began to bubble(冒泡).The steam rose from the spout(壶嘴) and soon the lid(盖子) was moved up.But when he looked under the lid, he could see nothing but water.He asked his grandma what moved the lid up.She replied that the water made steam and the steam moved up the lid.
However, he further asked, "If the steam from so little water is so strong, why wouldn't the steam from a great deal of water be a great deal stronger? Why couldn't it be made to move up a much greater weight? Why couldn't it be made to turn wheels?"
With no answers to these questions, his grandma made no reply.She went about her work quietly and the boy kept studying the teakettle in his place.
As the boy grew up, he never gave up looking for answers to those questions.Finally, he succeeded in finding them.The little boy is James Watt, the world-famous inventor of the first successful form of the steam engine.
