英语笑话：假如在学校看书，牛顿就不会发现万有引力

　　The teacher was vividly describing the discovery of the law of gravitation. He tried to make the children impressed with its importance.

　　He said, "Isaac Newton was sitting on the ground looking at the tree. An apple suddenly fell on his head. It led him discover gravitation." And he added, "Isn't that wonderful?"

　　The "smart boy" in the class replied in a high voice: "Yes, teacher, and he was very fortunate. If looking at his books, he wouldn't have discovered anything."

　　教师很生动地描述万有引力定律的发现，他想让学生对它的`重要性留下深刻的印象。

　　他说：“艾萨克·牛顿坐在地上，望着那棵树。忽然又一个苹果掉下来落到他的头上。这就促使他发现了万有引力。”他还接着说：“这不是很奇妙吗?”

　　这时班上那个被叫做“精仔”的男孩尖着嗓子回答说：“是的，老师，而且还很幸运。如果他是坐在学校里看着书本，就什么也不会发现了。”
