James Watt was an English boy. He was very clever and liked to ask questions.

One day, the boy was sitting in his grandmother’s kitchen. Above the fire an old-fashioned teakettle was hanging. The water within it was beginning to bubble. A thin cloud of steam was rising from the spout(壶嘴). Soon the lid(盖子)began to rattle and shake. The hot vapor puffed(冒出)out at a fast rate. Yet when the boy glanced under the lid he could see nothing.

“Grandma, what’s in the kettle?” little Watt asked. “Water, my child-nothing but water.” his grandma answered.” But I know there is something else. There is something under the lid and makes it rattle.” Grandmother laughed. “Oh, that is only steam,” she said. “You can see it coming out of the spout and puffing up under the lid.” “But you said there was nothing but water in the kettle. How did the steam get under the lid?” “Why, my dear, it comes out of the hot water. The hot water makes it.”

James lifted the lid and glanced inside again. He could see nothing but the bubbling water. The steam was not visible until it was fairly out of the kettle. “How strange!” he said. “The steam must be very strong to lift the heavy iron lid. Grandma, how much water did you put into the kettle?” “About a quart, James.” “Well, if the steam from so little water is so strong, why would not the steam from a great deal of water be a great deal stronger? Why couldn’t it be made to lift a much greater weight? Why couldn’t it be made to turn wheels?” Grandmother made no reply. These questions were more puzzling than profitable, she thought. She went about her work silently, and James sat still in his place and studied the teakettle.

So many years later, James Watt tried hard to make steam work for people. Finally he became very famous because he invented the first steam engine.
