A man tried to catch monkeys to sell them to zoos. The monkeys were very clever and every kind of trick that he set wasn't successful.

    A young boy watched the man's {#blank#}1{#/blank#} (努力) and then took a pot with a small neck. He placed some corn around the pot and put much corn in it. He then tied the pot to a tree and he told the man, "We will {#blank#}2{#/blank#}(很可能) have a monkey in a few hours."

    Soon, many monkeys were happy {#blank#}3{#/blank#}(发现) the corn and the pot. One put his hand into the pot easily and got {#blank#}4{#/blank#}(大量；充足) of corn, but he couldn't take out his hand with corns out of the small opening of the pet. The monkey got {#blank#}5{#/blank#} (生气) and began to cry. Some of the other monkeys tried very hard, but before they {#blank#}6{#/blank#}  (做成) 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 a[l ran away {#blank#}7{#/blank#}(除了) the one with its hand in the pot. The boy put the monkey and the pot into the bag. The man was {#blank#}8{#/blank#}(惊讶的) and asked the boy the {#blank#}9{#/blank#} (秘密) of his monkey trick. "Why was it so easy for the monkey to get his hand in but so difficult to get it out?"

    “The monkey could get his hand back out if he let go of the corn in the pot, but he just didn't want to let go. So he {#blank#}10{#/blank#} (惩罚) because of that," the boy laughed and said.
