谁能帮我做一下新概念英语第三册第一课A PUMA AT LARGE 的课文分析啊，不是语法和词汇欧，谢谢欧

Question

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. 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.
就是讲讲怎样行文的啊 Development of the text

Answer 1

美洲狮是大型猫类是在美国发现的动物。当伦敦动物园接到报告，一只野生的美洲狮在被发现四五英里以南的伦敦，他们并没有受到重视。然而，随着证据越来越多，动物园的专家们感到有必要进行调查，因为人们谁声称见到过美洲狮所描述的，出奇地相似。
为美洲狮狩猎开始在一个小村庄，一位妇女在采摘黑莓时的看见从她的'一只大猫'只有五码远。它就立刻逃走了，当她看见了，专家证实，美洲狮不会攻击人，除非是走投无路。事实上搜寻工作很困难，因为美洲狮往往是在一个上午进行观察，在另一个地方在20英里外的夜晚。无论它走哪儿，留下一串死鹿及死兔子之类的小动物。爪子印在许多地方和美洲狮皮毛被发现，灌木丛看到抱住。有人抱怨“猫的叫声在夜晚;一位商人去钓鱼，看见那只美洲狮在树上。专家们如今已经完全肯定那只动物就是美洲狮，但它来自哪儿？由于没有了美洲狮据报道，从全国动物园中的任何缺失，这其中一定是在一个私人收藏豢养的，不知怎么设法逃出来了。搜寻工作进行了好几个星期，但始终未能逮住那只美洲狮。令人不安的是认为一个危险的野生动物仍然在宁静的乡村大。

美洲狮是一种体型似猫的大动物，产于美洲。当伦敦动物园接到报告说，在伦敦以南四十五英里处发现一头野生美洲狮，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，因为事实上上见到过美洲狮人们所描述的情况竟是出奇的相似。
搜寻美洲狮的工作是从一座小村庄开始。那里的一位妇女在采摘黑莓看见＂一只大猫＂离她仅五码远，她刚看见它，它就立刻逃走了。专家证实，美洲狮除非被逼得走投无路，否则是绝不会伤人的。事实上搜寻工作很困难因为，常常是早晨在甲地发现那只美洲狮，晚上却在二十英里外的异地发现它的踪迹。
