A poor traveler arrived at a small village. He had no food or money. He only had a cooking pot. He

made a small cooking fire, placed his pot on it, and poured in some water. When a few villagers asked 

what he was doing, he said that he was making stone soup which was a recipe passed down from his 

father. He then dropped (扔) a round stone into the pot.

Then the traveler told the villagers stories of his travels and the exciting things he’d seen. He tasted 

(品尝) his soup and said it was nice, but a bit of salt would be better. One villager went home and came

back with some salt for the soup.

A few more villagers stopped to see what was going on when they heard the traveler speaking. The 

traveler told more stories and said that some carrots or onions would be nice to the delicious soup. So
