Lesson 1A Puma at large逃遁的美洲狮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 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.

Most of us have formed an unrealistic picture of life on a desert island. We sometimes imagine a desert island to be a sort of paradise where the sun always shines. Life there is simple and good. Ripe fruit falls from the trees and you never have to work. The other side of the picture is quite the opposite. Life on a desert island is wretched. You either starve to death or live like Robinson Crusoe, Waiting for a boat which never comes. Perhaps there is an element of truth in both these pictures, but few us have had the opportunity to find out. Two men who recently spent five days on a coral island wished they had stayed there longer. They were taking a badly damaged boat from the Virgin Islands to Miami to have it repaired. During the journey, their boat began to sink. They quickly loaded a small rubber dinghy with food, matches, and cans of beer and rowed for a few miles across the Caribbean until they arrived at a tiny coral island. There were hardly any trees on the island and there was no water, but this did not prove to be a problem. The men collected rainwater in the rubber dinghy. As they had brought a spear gun with them, they had plenty to eat. They caught lobster and fish every day，and, as one of them put it ate like kings. When a passing tanker rescued them five days later, both men were genuinely sorry that they had to leave.New words and expressions 生词和短语desert island荒岛 unrealistic adj. 不真实paradisen. 天堂，乐士 wretched adj. 可怜的，艰苦的starvev. 挨饿 element n. 成分opportunityn. 机会 coral n. 珊瑚Virgin Islands维尔京群岛 Miami n. 迈阿密（美国最南的城市）dinghyn. 救生筏，小船 Caribbean n. 加勒比海spear gun捕鱼枪 lobster n. 龙虾tankern. 油轮 genuinely adv. 由衷地Robinson Crusoe鲁滨孙.克鲁索（小说鲁滨孙漂流记主人公） 参考译文 我们许多人对于荒岛生活有一种不切实际的想法。我们有时想象荒岛是阳光终日普照的天堂。在那里，生活简单又美好。成熟的水果从树上掉下来，人们根本无需劳动。另一种想法恰恰相反，认为荒岛生活很可怕，要么饿死，要么像鲁滨孙那样，天天盼船来，却总没见船影。也许，这两种都像都有可信之处。但很少有人能有机会去弄个究竟。 最近有两个人在一座珊瑚岛上呆了 5 天，他们真希望在那儿再多呆一些日子。他们驾着一条严重损坏的小船从维尔京群岛阿密修理。途中，船开始下沉，他们迅速把食物、火柴、罐装啤酒往一只救生筏上装。然后在加勒比海上划行了几英里，到了一座珊瑚岛上。岛上几乎没有一颗树，也没有淡水，但这不算什么问题。他们用像皮艇蓄积雨水。由于他们随身带了一支捕鱼枪，因此，吃饭不愁。他们天天捕捉龙虾和鱼，正如其中一位所说，吃得“像国王一样好”。5 天后，一条油轮从那儿路过，搭救了他们。这二位不得不离开那个荒岛时，还真的感到遗憾呢！Lesson 22By heart熟记台词Listen to the tape then answer the question below.听录音，然后回答以下问题。 Which actor read the letter in the end, the aristocrat or the gaoler?Some plays are so successful that they run for years on end, In many ways, this is unfortunate for the poor actors who are required to go on repeati
