Lesson 1 A puma at large

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.

解析：

1 When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.

这句话中spot做了动词，表示看到，如在很多物品题中gift, book, clothes等，甚至看到一个地点如park，swimming pool 等，甚至人物题neighbour，famous person等

When she spotted the gift, she picked it up.当她看到这本书时，她把它拿起来了。

When I spotted this book, I couldn't help walking towards it and had a good read.我看到这本书时，忍不住走过去研读了一番。

When I spotted this piece of clothes, I was deeply impressed by it. 当我看见这件衣服时，我被它深深地吸引了。

2 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.

这里的feel obliged to do sth. 表示感到不得不做某事，大家可以用在weather话题，表示天气糟糕，不得不做某事，V-T If you are obliged to do something, a situation, rule, or law makes it necessary for you to do that thing. 迫使例The storm got worse and worse. Finally, I was obliged to abandon the car and continue on foot.暴风雨越来越猛烈。最终，我被迫弃车徒步前行。

也可以在交通话题，public transport 如果说堵车，那就是不得不等上很久

We were struck in thick traffic, so we felt obliged to wait for ages.我们堵在拥堵的交通里了，不得不等很久。

或者在等待这种话题A time you waited for something special   大家可以说自己在等成绩，不得不在门口等之类的。

3 It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered.

这里的corner很棒，是个动词，表示v.使走投无路，使陷入困境

V-T If you corner a person or animal, you force them into a place they cannot escape from. 使走投无路

例A police motorcycle chased his car twelve miles, and cornered him near Gainsborough.一辆警车追踪他的汽车12英里，在盖恩斯堡附近把他逼得走投无路。

（大家可以在电影，书等话题中描述情节可以用哦，或者在动物类话题）

4 Wherever it went, it left behind it a trail of dead deer and small animals like rabbits.

这里的a trail of 很棒，后面接可数和不可数都行，如：a trail of blood 一串血迹 （action movie 话题，动物话题）, a trail of mud 一串泥迹（countryside话题，rainy day 话题），a trail of destruction 一系列破坏 （动物话题）, a trail of broken promises 一系列实现不了的承诺（government相关话题）

5 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.

这里的somehow值得学习哦

ADV You use somehow to say that you do not know or cannot say how something was done or will be done. 不知怎地; 不知以什么方式

例We'll manage somehow, you and me. I know we will.

我们总会应付过去的，你和我。我知道我们会的。（聪明的人这个话题）

Somehow Karin managed to cope with the demands of her career.

不知怎么地，卡林设法应付了那些来自工作的要求。（work话题）
