题型:选择题

When Colonel Harland Sanders retired at the age of 65, he had little to show for himself, except an old Caddie roadster, a $105 monthly pension check ,and a recipe for chicken.

Knowing he couldn’t live on his pension, he took his chicken recipe in hand, got behind the wheel of his van (货车),and set out to make his fortune. His first plan was to sell his chicken recipe to restaurant  owners, who would in turn give him a residual (酬金)for every piece of chicken they sold—5 cents per chicken. The first restaurateur he called on turned him down.

So did the second.

So did the third.

In fact, the first 1,008 sales calls Colonel Sanders made ended in rejection. Still, he continued to call on owners as he traveled across the USA, sleeping in his car to save money. Prospect number 1,009 gave him first “yes”.

After two years of making daily sales he had signed up a total of five restaurants. Still the Colonel pressed on , knowing that he had a great chicken recipe and that someday the idea would catch on .

Of course, you know how the story ends. The idea did catch on. By 1963 the Colonel had 600 restaurants across the country selling his secret recipe of Kentucky Fried Chicken (with ll herbs and spices ).

In 1964 he was bought out by future Kentucky governor John Brown.Even though the sale made him a multi-millionaire, he continued to represent and promote KFC until his death in 1990.
