    　　So the man sold his few belongs, bought some simple supplies, camped on the beach, and began 　　7　　 pebbles．He knew that if he picked up common pebbles and threw 　　8　　 down again, he might pick up the same pebble hundreds of times．So, when he felt one that was cold, he threw it into the sea．He spent a whole day 　　9　　 this, but none of them was the touchstone．Yet he went on and on this way．Pick up a pebble．Cold－throw; it into the sea．Pick up 　　10　　 Cold－throw it into the sea．

    　　The days stretched into weeks and the weeks into months and the months 　　11　　 years．One day, however, about mid-afternoon, he picked up a pebble and it was warm．He threw it into the sea 　　12　　 he realized what he had done．He had formed 　　13　　 a strong habit of throwing each pebble into the sea that when the one he wanted came along, he 　　14　　 threw it away．
