James Bender,in his book How to Talk Well tells the story of a farmer who grew award-winning corn.Each year he won a blue ribbon.One year a newspaper reporter interviewed him and learned something interesting about how he grew it.
The reporter discovered that the farmer shared his seed corn with his neighbors."How can you afford to share your best seed corn with your neighbors when they are entering corn in competition with yours each year?" the reporter asked."Why," said the farmer,"didn't you know?The wind picks up pollen（花粉） from the ripening corn and carries it from field to field.If my neighbors grow bad corn,cross-pollination（异花受粉） will slowly reduce the quality of my corn.If I am to grow good corn,I must help my neighbors grow good corn."
He is very much aware of the connectedness of life.His corn cannot improve unless his neighbors' corn also improves.The lesson for each of us is this：If we are to grow good corn,we must help our neighbors grow good corn.
