Lesson 1 A puma at large
Listen to the tape then answer the question below. Where must the puma have come from? Pumas are large, cat-like animals which are found in America. When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously. However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar. The hunt for the puma began in a small village where a woman picking blackberries saw 'a large cat' only five yards away from her. It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered.

逃遁的美洲狮
听录音，然后回答以下问题。 狮子从何而来？ 美洲狮是一种体形似猫的大动物，产于美洲。 当伦敦动物园接到报告说，在伦敦以南45英里处发现一只美洲狮时，这些报告并没有受到重视。 可是，随着证据越来越多，动物园的专家们感到有必要进行一番调查， 因为凡是声称见到过美洲狮的人们所描述的情况竟是出奇地相似。 搜寻美洲狮的工作是从一座小村庄开始的。那里的一位妇女在采摘黑莓时的看见“一只大猫”，离她仅5码远。 她刚看见它，它就立刻逃走了。专家证实，美洲狮非被逼得走投无路，是决不会伤人的。
