有一年,法国西部农场种植出一种清脆、爽口的高山苹果,但由于风沙和冰雪袭击,苹果周身斑点密集,不耐看,数千万美元的苹果滞销。农民在走投无路之际,请高手设计了这样一条广告: “高山苹果特别爽口好吃,周身斑点正是它区别于其它苹果的最佳辨别标识。” In one year, a crisp, refreshing alpine apple was planted on the farms in western France. However, due to the sandstorm and ice and snow attacks, the apple was densely spotted and impassible, and tens of millions of dollars of apples were unmarketable. When the peasants are desperate, they ask the master to design such an advertisement: “Alpine apples are particularly refreshing and delicious, and the whole body is the best distinguishing mark from other apples.”
