Once upon a time, a big lion lived in a zoo. One day, he {#blank#}1{#/blank#} (be) very hungry. When Bill, the keeper, gave{#blank#}2{#/blank#}his dinner, he ate it up quickly. Quite by mistake he ate up the keeper too. {#blank#}3{#/blank#}it was time for lunch, Bill did not show up. The other keepers sat down to eat, still wondering {#blank#}4{#/blank#} young Bill was not there. {#blank#}5{#/blank#} (sudden) there came a loud sound from the Lion House. They went {#blank#}6{#/blank#} (see) what was the matter. There they saw the big lion {#blank#}7{#/blank#} (lie) on the ground. He looked{#blank#}8{#/blank#} (big) than before. The keepers looked at one another and all of them said at once, “Of course! The big lion has eaten poor Bill.” They got two {#blank#}9{#/blank#} (bottle) of medicine quickly, and then they made the big lion sleep for {#blank#}10{#/blank#}operation (手术). They cut up the front of his belly (肚子).Bill jumped out from it, looking quite all right.
