A teacher to his students a story: One entomologist and his business friends in the park, walking, talking. Suddenly, he stopped in, as if to hear something. "How is it?" He asked his businessman friend. Surprise entomologist cried: "hear me? A cricket chirping, and certainly is a top grade of major cricket." Businessman friend to struggle to pricking up her hearing for a long time, no alternative but to reply: "I do not hear anything!" "You wait." Entomologist spoke, he trotted to the nearby forests of the past. Soon, he found a big head of cricket, come back and tell his friends: "see? A big white teeth purple wings of crickets, this is a general class cricket yo! How, I heard right ? " "Yes, you heard him correctly." Businessman inexplicably asked entomologist: "You not only hear the crickets chirping, and hear the crickets of the species - how can you hear out of it?" Entomologist replied: "tall big cricket sounds slow, sometimes called two or three hours of sound. Small crickets call frequency in fast, scream also ground. Black, purple, red, yellow and other colors of cricket called sound is different, for example, crickets chirping sound in yellow with a metal sound. all of their calls is only very slight, or even words can not describe the difference, you must do to distinguish it. " They spoke, he left the park, walking in the busy side of the road pavement. Suddenly, the pace of business has stopped, bent down picked up a coin dropped on the floor. The entomologist is still great strides walked, did not hear the voice of the coin landing. "This story illustrates the rationale?" Lu asked my teacher. Everybody is thinking, no one answered. So for a while, Lu teacher has given the answer: "an entomologist's heart, where the worms, so he could hear crickets chirping. Merchants heart is in the money there, so he could hear the sound of coins. This story illustrates, your heart where your happiness lies. Your heart is under the direction of the direction of happiness, happiness needs careful to water. http://www.puma-shoes1.com puma store
