A man tried to catch monkeys to sell them to zoos. The monkeys, however, were very c1. and every kind of trap(计谋) that he set failed.

A young boy watched the man’s efforts and then took a pot (壶) with a narrow neck(瓶颈). He placed a few peanuts around the pot and put lots of peanuts i2. it. He then tied the pot to a tree and he told the man, “We should have a m3.in a few hours.”

Some monkeys soon found the peanuts and the pot. One put his hand into the pot e4. and got a handful of peanuts, but he couldn’t pull his h5. with peanuts out of the narrow neck of the pot. The monkey was a6. and began to cry. Some of the other monkeys tried unsuccessfully to pull the pot off his hand.

The boy and the man heard the noise. As the boy came near to the monkeys with a bag, the monkeys all ran away e7. the one with its hand in the pot. The boy packed the monkey and the pot into the bag. The man was s8. and asked the boy the secret of his monkey trap(圈套). “Why was it so easy for the monkey to get his hand in but so h9. to get it out?”

The boy laughed and said, “The monkey could get his hand back out if he let go of the peanuts in the pot, but he just wasn’t w10. to let go. They never are.
