Immanuel Nobel invented landmines and made a lot of money from the government during the Crimean War(克里米亚战争), but went bankrupt soon after.

He spent much time and money working on how to end the wars, and the peace between nations, until he died in Italy in 1896. His famous last will, in which he left money to provide prizes for outstanding work in physics, chemistry, physiology or medicine, literature and peace, is a memorial to his interests and ideas.

    Many years ago, there lived an old man with his three sons, Dharma, Harrison and Keith, in a village. The man worked hard when he was young, so he had the largest farmyard and the most beautiful house in the village. However, his sons were all born to be lazy, which made him disappointed. He was worried that his sons would use up his money and starve to death.

    One day, the old man came up with a plan. He called his sons and said to them, "Look, my dear sons. There is lots of hidden gold in the land at the farmyard. If you work together, you may find it."

    In a wish to find out the gold, his sons worked hard from the morning to the evening digging and digging all through the land. Three days had passed, but they didn't find what they were looking for. They got frustrated and angry. They decided to give up and returned to ask their father.

    "There is no gold in the land. We are cheated."

    "Since the land has been dug soft, why don't you plant some crops there?" was the reply of the father to the sons.

    Off went the sons. Soon the whole once useless land was rich crops.

    "This is the real gold, my sons," said the proud father.
