Some people were steaming peas under a tree in order to make a meal for their horses. Up in the branches sat a monkey,  36 what they were doing.
"Aha" thought the monkey. “I spot my  37 !” So when the men had finished steaming the peas and 38 for a moment to look after the horses,  39 ,the monkey let himself down from the tree. He snatched (抓) the peas and filled his  40 and both hands as full as they could 41 . Then he climbed up the tree and sat there, eating happily.
Suddenly one pea fell.
"Oh dear! Oh my pea!" cried the monkey. The other peas  42 to drop out of his mouth. He 43 his hands in despair(绝望地), and the peas fell out of his hands too, but he took no  44 . All he thought of was that one pea was gone,__45__ he climbed down the trunk to hunt for his lost pea on the ground. At this time, the men came back. When they saw a monkey  46 with their pots, they all  47 their arms and shouted, "Shoo! Shoo!" Then they picked up stones and began to 48 the monkey with them. The monkey was so 49 that he gave one jump to the nearest 50 , and swung himself up to the top of the tree.
