Once in Japan there lived two frogs, one of whom made his home near the town of Osaka, while the other lived in Kyoto. 36 , they didn’t know each other. Bothof them liked to see a little of the world: the Kyoto frog wanted to visit Osaka, and the Osaka frog wished to go to Kyoto.
So one morning they 37. However, the journey was more 38 than they had expected, for they didn’t know much about traveling. Half-way between the two towns, at the top of a mountain, the two frogs 39 each other! Soon they fell into 40 .
“What a(n) 41 we are too small, ” said the Osaka frog. “Otherwise, we could see both towns from here, and 42 if it is worth our going on.”
“Oh, that is easily 43 ,” replied the Kyoto frog. “We have only got to stand up on our hind (后面的) legs, and hold on to each other 44 we won’t fall down, and then we can both look at the towns we are 45 to.”
This idea 46 the Osaka frog; he stood up and put his front paws on the 47 of the other frog, who had risen also. There they both stood, stretching themselves as 48 as they could. The Kyoto frog turned his nose towards Osaka, and the Osaka frog, towards Kyoto, but the 49 frogs forgot that when they stood up, their eyes were in the backs of their heads, and that 50 their noses pointed to their destinations, yet their eyes looked at the places 51 which they had come.
“Dear me!” cried the Osaka frog. “Kyoto is 52 like Osaka. It is certainly not worth such a long journey.”
“If I had known that Osaka was only a 53 of Kyoto I should never have traveled all this way,” 54 the frog from Kyoto. Then they started off for their 55 again.
