An English padre（神父） wanted to become a member of a certain club in Africa. In order to become a member, each person had to   1  at least one lion. The padre had never shot an animal for his life. So, armed with a rifle and led by a young African boy, the padre set out one evening for a pool in the jungle where he was told a lion came each evening to   2  . He waited patiently for a few   3  until shortly before midnight when he heard a rustling(沙沙声) noise. Sure enough a few feet away the head of the lion appeared above a bush that separated the padre and the pool. He aimed and fired. The head of the lion   4  fell behind the bush but a moment later

   5  . So the padre aimed and   6  again. The head of the lion fell behind the bush and once more reappeared. The padre fired again: the same   7  . He remained calm because he   8  he had brought sixteen bullets with him. After his fourth try, his aim seemed to become more and more   9  : in fact, after his  10  

try the African boy had to  11  him: “This is your last chance. If you  12  this time, we are in trouble.” The padre then realized how  13  the situation was, so he took a deep breath, aimed very carefully and fired. They waited for a moment, and then slowly  14  up to twenty: the head of the lion did not reappear. The padre was certain that at last he had shot his lion. They  15  forward together to the spot behind the bush. And what do you think they found? Sixteen lions!
