Listen to the tape then answer the question below. 听录音，然后回答以下问题。 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 de<I>script</I>ions 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. The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening. Wherever it went, it left behind it a trail of dead deer and small animals like rabbits. Paw prints were seen in a number of places and puma fur was found clinging to bushes. Several people complained of "cat-like noises' at night and a businessman on a fishing trip saw the puma up a tree. The experts were now fully convinced that the animal was a puma, but where had it come from? As no pumas had been reported missing from any zoo in the country, this one must have been in the possession of a private collector and somehow managed to escape. The hunt went on for several weeks, but the puma was not caught. It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside.

一般来讲定语从句和同位语从句紧随在被修缮名词后面，但为了保持句子平衡，也可以把谓语动词放到从句之前
定语从句只是对于被修缮词的补充说明、修缮； 同位语从句则是讲述被修饰名词的内容 定语从句的引导词： 指人：主语who; 宾语who/whom; 定语 whose 表达事物：that（也可以指人）/which 时间状语：when; 地点状语：where; 原因状语：why 同位语从句：名词做主语、宾语等，关系词用that而不是which 时间－when； 地点－where An idea came to her that she might do the experiment in another way. I have no idea what has happened to him。 定语从句中没有what这个关系词，但它可以引导同位语从句
take sth.seriously :deal with sth.seriously take sth.lightly
as: 随着 过去分词做定语 声称曾经做过某事：claim to have done sth.
I still remember the school where I studied English.
confirm: be sure,be certain
