Lesson 42 Modern cavemen 现代洞穴人
Cave exploration, or pot-holing, as it has come to be known, is a relatively new sport. Perhaps it is the desire for solitude or the chance of making an unexpected discovery that lures people down to the depths of the earth. It is impossible to give a satisfactory explanation for a pot-holer's motives. For him, caves have the same peculiar fascination which high mountains have for the climber. They arouse instincts which can only be dimly understood. Exploring really deep caves is not a task for the Sunday afternoon rambler. Such undertakings require the precise planning and foresight of military operations. It can take as long as eight days to rig up rope ladders and to establish supply bases before a descent can be made into a very deep cave. Precautions of this sort are necessary, for it is impossible to foretell the exact nature of the difficulties which will confront the pot-holer. The deepest known cave in the world is the Gouffre Berger near Grenoble. It extends to a depth of 3,723 feet. This immense chasm has been formed by an underground stream which has tunneled a course through a flaw in the rocks. The entrance to the cave is on a plateau in the Dauphine Alps. As it is only six feet across, it is barely noticeable. The cave might never have been discovered had not the entrance been spotted by the distinguished French pot-holer, Berger. Since its discovery, it has become a sort of pot-holers' Everest(珠峰). Though a number of descents have been made, much of it still remains to be explored. A team of pot-holers recently went down the Gouffre Berger. After entering the narrow gap on the plateau, they climbed down the steep sides of the cave until they came to narrow corridor. They had to edge their way along this, sometimes wading across shallow streams, or swimming across deep pools. Suddenly they came to a waterfall which dropped into an underground lake at the bottom of the cave. They plunged into the lake, and after loading their gear on an inflatable rubber dinghy, let the current carry them to the other side. To protect themselves from the icy water, they had to wear special rubber suits. At the far end of the lake, they came to huge piles of rubble which had

been washed up by the water. In this part of the cave, they could hear an insistent booming sound which they found was caused by a small water-spout shooting down into a pool from the roof of the cave. Squeezing through a cleft in the rocks, the pot-holers arrived at an enormous cavern, the size of a huge concert hall. After switching on powerful arc lights, they saw great stalagmites -- some of them over forty feet high -- rising up like tree-trunks to meet the stalactites suspended from the roof. Round about, piles of limestone glistened in all the colours of the rainbow. In the eerie（可怕的） silence of the cavern, the only sound that could be heard was made by water which dripped continuously from the high dome above them.
洞穴勘查——或洞穴勘探——是一项比较新的体育活动。寻求独处的愿望或寻求意外发现的机会的欲望吸引人们来到地下深处。要想对洞穴探险者的动机作出满意的解释是不可能的。对洞穴探险者来说，洞穴有一种特殊的魅力，就像高山对登山者有特殊魅力一样。为什么洞空能引发人的那种探险本能，人们对此只能有一种模模糊糊的理解。
探测非常深的洞穴不是那些在星期日下午漫步的人所能胜任的。这种活动需要有军事行动般的周密布署和预见能力。有时需要花费整整8天时间来搭起绳梯，建立供应基地，然后才能到一个很深的洞穴里。作出这样的准备是必要的，因为无法预见到洞穴探险者究竟会遇到什么性质的困难。世界上最深的洞穴是格里诺布尔附近的高弗.伯杰洞，深达3,723英尺。这个深邃的洞穴是由一条地下暗泉冲刷岩石中的缝隙并使之慢慢变大而形成的。此洞的洞口在丹芬阿尔卑斯山的高原上，仅6英尺宽，很难被发现。若不是法国著名洞穴探险家伯杰由于偶然的机会发现了这个洞口的话，这个洞也许不会为人所知。自从被发现以后，这个洞成了洞穴探险者的珠穆朗玛峰，人们多次进入洞内探险，但至今尚有不少东西有待勘探。
最近，一队洞穴探险者下到了高弗.伯杰洞里。他们从高原上的窄缝进去，顺着笔直陡峭的洞壁往下爬。来到一条狭窄的走廊上。他们不得不侧着身子往前走，有时过浅溪，有时游过深潭。突然，他们来到一道瀑布前，那瀑布奔泻而下，注入洞底一处地下湖里。他们跳入湖中，把各种器具装上一只充气的橡皮艇，听任水流将他们带往对岸。湖水冰冷刺骨，他们必须穿上一种特制的橡皮服以保护自己。在湖的尽头，他们见到一大堆一大堆由湖水冲刷上岸的碎石。在这儿，他们可以听见一种连续不断的轰鸣声。后来他们发现这是由山洞顶部的一个小孔里喷出的水柱跌落到水潭中发出的声音。洞穴探险者从岩石缝里挤身过去，来到一个巨大的洞里，其大小相当于一个音乐厅。他们打开强力弧光灯，看见一株株巨大的石笋，有的高达40英尺，像树干似地向上长着，与洞顶悬挂下来的钟乳石相接。周围是一堆堆石灰石，像彩虹一样闪闪发光。洞里有一种可怕的寂静，唯一的可以听见的声响是高高的圆顶上不间断地滴水的嘀嗒声。
Lesson 43 Fully insured 全保险
Insurance companies are normally willing to insure anything. Insuring public or private property is a standard practice in most countries in the world. If, however, you were holding an open air garden party or a fete it would be equally possible to insure yourself in the event of bad weather. Needless to say, the bigger the risk an insurance company takes, the higher the premium you will have to pay. It is not uncommon to hear that a shipping company has made a claim for the cost of salvaging a sunken ship. But the claim made by a local authority to recover the cost of salvaging 第 14 页 共 52 页
a sunken pie dish must surely be unique. Admittedly it was an unusual pie dish, for it was eighteen feet long and six feet wide. It had been purchased by a local authority so that an enormous pie could be baked for an annual fair. The pie committee decided that the best way to transport the dish would be by canal, so they insured it for the trip. Shortly after it was launched, the pie committee went to a local inn to celebrate. At the same time, a number of teenagers climbed on to the dish and held a little party of their own. Dancing proved to be more than the dish could bear, for during the party it capsized and sank in seven feet of water. The pie committee telephoned a local garage owner who arrived in a recovery truck to salvage the pie dish. Shivering in their wet clothes, the teenagers looked on while three men dived repeatedly into the water to locate the dish. They had little difficulty in finding it, but hauling it out of the water proved to be a serious problem. The sides of the dish were so smooth that it was almost impossible to attach hawsers and chains to the rim without damaging it. Eventually chains were fixed to one end of the dish and a powerful winch was put into operation. The dish rose to the surface and was gently drawn towards the canal bank. For one agonizing moment, the dish was perched precariously on the bank of the canal, but it suddenly overbalanced and slid back into the water. The men were now obliged to try once more. This time they fixed heavy metal clamps to both sides of the dish so that they could fasten the chains. The dish now had to be lifted vertically because one edge was resting against the side of the canal. The winch was again put into operation and one of the men started up the truck. Several minutes later, the dish was successfully hauled above the surface of the water. Water streamed in torrents over its sides with such force that it set up a huge wave in the canal. There was a danger that the wave would rebound off the other side of the bank and send the dish plunging into the water again. By working at tremendous speed, the

men managed to get the dish on to dry land before the wave returned.
保险公司一般说来愿意承保一切东西。承办公共财产或私人财产保险是世界上大部分国家的正常业务。如果你要举办一次露天游园会或盛宴，为避免碰上不好的天气而遭受损失也同样可以保险。不用说，保险公司承担风险越大，你付的保险费也就越高。航运公司为打捞沉船而提出索赔，这是常有的事，但某地当局为打捞一只焙制馅饼的盘子提出索赔，倒是件新鲜事儿。
这个馅饼盘子确实少见，有18英尺长，6英尺宽。某地方当局买下它用来焙制一个巨大的馅饼为一年一度交易会助兴。馅饼委员会确认运输这只盘子的最佳方案是通过运河水运。于是，他们对这只盘子的运输安全投了保。盘子下水后不久，馅饼委员会成员们来到当地一家小酒店庆贺。就在这个时候，许多十几岁的孩子爬上盘子举行他们自己的集会。他们跳起了舞，盘子难以承受。舞会进行过程中，盘子倾覆，沉入了7英尺深的水中。
馅饼委员会给当地汽车修理库老板打电话，他闻讯后开着一辆急修车前来打捞盘子。那些孩子们穿着湿衣服哆嗦，看着3个工人轮番潜入水中以确定盘子的位置。他们没费多大事儿就找到了盘子，可是把盘子捞出却是一个很大的难题。盘子四边十分光滑，要在盘边拴上绳索或链条而同时又不损坏它是很难办到的。不过，他们终于将链条固定在盘子的一端，一台大功率的绞车开动起来。盘子慢慢浮出水面，被轻轻地拽向运河岸边。在令人忐忑不安的瞬间，盘子晃晃悠悠地上了岸，但它突然失去了平衡，又跌回水中。工人们只得再来一次。这次，他们用沉重的金属夹子把盘子夹住，以便往盘子上安装铁链。这次，盘子必须垂直吊出水面，因为盘子的一边紧靠着运河河岸。绞盘机再次启动，一位工人发动了急修车的引擎。几分钟后，盘子被成功地拽出了水面。波浪从盘子两侧急涌而出，在运河里掀起一股大浪。但是当波浪从河对岸折回来时，就有再次把盘子拖进水里的危险。工人们动作迅速，终于赶在那股大浪返回之前把盘子拽到了岸上。
Lesson 44 Speed and comfort 又快捷又舒适
People, traveling long distances frequently have to decide whether they would prefer to go by land, sea, or air. Hardly anyone can positively enjoy sitting in a train for more than a few hours. Train compartments soon get cramped and stuffy. It is almost impossible to take your mind off the journey. Reading is only a partial solution, for the monotonous rhythm of the wheels clicking on the rails soon lulls you to sleep. During the day, sleep comes in snatches. At night, when you really wish to go to sleep, you rarely manage to do so. If you are lucky enough to get a sleeper, you spend half the night staring at the small blue light in the ceiling, or fumbling to find your ticket for inspection. Inevitably you arrive at your destination almost exhausted. Long car journeys are even less pleasant, for it is quite impossible even to read. On motorways you can, at least, travel fairly safely at high speeds, but more often than not, the greater part of the journey is spent on roads with few service stations and too much traffic. By comparison, ferry trips or cruises offer a great variety of civilized comforts. You can stretch your legs on the spacious decks, play games, meet interesting people and enjoy good food----always assuming, of course, that the sea is calm. If it is not, and you are likely to get sea-sick, no form of transport could be worse. Even if you travel in
