1、Lesson 1 Finding fossil man 发现化石人We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. But there are some parts of the word where even now people cannot write. The only way that they can preserve their history is to recount it as sagas - le
2、gends handed down from one generation of another. These legends are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesian peoples now living in the Pacifi
3、c Islands came from. The sagas of these people explain that some of them came from Indonesia about 2,000 years ago. But the first people who were like ourselves lived so long ago that even their sagas, if they had any, are forgotten. So archaeologists have neither history nor legends to
4、 help them to find out where the first 'modern men' came from. Fortunately, however, ancient men made tools of stone, especially flint, because this is easier to shape than other kinds. They may also have used wood and skins, but these have rotted away. Stone does not decay, and
5、 so the tools of long ago have remained when even the bones of the men who made them have disappeared without trace.参考译文 我们从书籍中可读到5,000 年前近东发生的事情，那里的人最早学会了写字。但直到现在,世界上有些地方，人们还不会书写。 他们保存历史的唯一办法是将历史当作传说讲述，由讲述人一代接一代地将史实描述为传奇故事口传下来。人类学家过去不清楚如今生活在太平洋诸岛上的波利尼西亚人的祖先来自何方，当地人的传说却告诉人们：其中一部分是约在2,00
6、0年前从印度尼西亚迁来的。 但是，和我们相似的原始人生活的年代太久远了，因此，有关他们的传说既使有如今也失传了。于是，考古学家们既缺乏历史记载，又无口头传说来帮助他们弄清最早的“现代人”是从哪里来的。 然而， 幸运的是，远古人用石头制作了工具，特别是用燧石，因为燧石较之其他石头更容易成形。他们也可能用过木头和兽皮，但这类东西早已腐烂殆尽。石头是不会腐烂的。因此，尽管制造这些工具的人的骨头早已荡然无存，但远古时代的石头工具却保存了下来。Lesson 2 Spare that spider 不要伤害蜘蛛 W
7、hy, you may wonder, should spiders be our friends? Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for
8、 the protection we get from insect-eating animals. We owe a lot to the birds and beasts who eat insects but all of them put together kill only a fraction of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, spiders never do the harm to us or our belongings. &n
9、bsp;Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always has eight legs and insect never more than six. How many spiders are engaged in this work no our behalf? One authority on spiders made a
10、 census of the spiders in grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre; that is something like 6,000,000 spiders of different kinds on a football pitch. Spiders are busy for at least half the year in killing insects. It is impossible to make m
11、ore than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country
12、.参考译文 你可能会觉得奇怪， 蜘蛛怎么会是我们的朋友呢？因为它们能消灭那么多的昆虫，其中包括一些人类的大敌，要不是人类受一些食虫动物的保护，昆虫就会使我们无法在地球上生活下去，昆虫会吞食我们的全部庄稼，杀死我们的成群的牛羊。我们要十分感谢那些吃昆虫的鸟和兽，然而把它们所杀死的昆虫全部加在一起也只相当于蜘蛛所消灭的一小部分。此外，蜘蛛不同于其他食虫动物，它们丝毫不危害我们和我们的财物。 许多人认为蜘蛛是昆虫，但它们不是昆虫，甚至与昆虫毫无关系。人们几乎一眼就能看出二者的差异，因为蜘蛛都是8条腿，而昆虫的腿从不超过6条。 &nbs
13、p;有多少蜘蛛在为我们效力呢？一位研究蜘蛛的权威对英国南部一块草坪上的蜘蛛作了一次调查。他估计每英亩草坪里有225万多只蜘蛛。这就是说，在一个足球场上约有600万只不同种类的蜘蛛。蜘蛛至少有半年在忙于吃昆虫。它们一年中消灭了多少昆虫，我们简直无法猜测，它们是吃不饱的动物，不满意一日三餐。据估计，在英国蜘蛛一年里所消灭昆虫的重量超过这个国家人口的总重量。Lesson 3 Matterhorn man 马特霍恩山区人 Modern alpinists try to climb mountains by a route which will give
14、 them good sport, and the more difficult it is, the more highly it is regarded. In the pioneering days, however, this was not the case at all. The early climbers were looking for the easiest way to the top, because the summit was the prize they sought, especially if it and never been attained before
15、. It is true that during their explorations they often faced difficulties and dangers of the most perilous nature, equipped in a manner with would make a modern climber shudder at the thought, but they did not go out of their way to court such excitement. They had a single aim, a solitary goal - the
16、 top! It is hard for us to realize nowadays how difficult it was for the pioneers. Except for one or two places such as Zermatt and Chamonix, which had rapidly become popular, Alpine village tended to be impoverished settlements cut off from civilization by the high mountains. Such inns
17、 as there were generally dirty and flea-ridden; the food simply local cheese accompanied by bread often twelve months old, all washed down with coarse wine. Often a valley boasted no inn at all, and climbers found shelter wherever they could - sometimes with the local priest (who was usually as poor
18、 as his parishioners), sometimes with shepherds or cheese-makers. Invariably the background was the same: dirt and poverty, and very uncomfortable. For men accustomed to eating seven-course dinners and sleeping between fine linen sheets at home, the change to the Alps must have very hard indeed.参考译文
19、 现代登山运动员总想找一条能够给他们带来运动乐趣的路线来攀登山峰。他们认为， 道路愈艰险愈带劲儿。然而，在登山运动的初期，全然不是这种情况。早期登山者所寻找的是通往山顶的最方便的途径，因为顶峰特别是前人未曾到过的顶峰 - 才是他们寻求的目标。确实，在探险中他们经常遇到惊心动魄的困难和危险，而他们装备之简陋足以使现代登山者一想起来就胆战心惊。但是，他们并非故意寻求这种刺激，他们只有一个目标，唯一的目标 - 顶峰！ 我们今天很难想像昔日的登山先驱们是多么艰苦。除了泽曼特和夏蒙尼等一两个很快出了名的地方外，阿尔卑斯山山区的小村几乎全是高山环抱、与世
20、隔绝的穷乡僻壤。那里的小客栈一般都很肮脏，而且跳蚤猖獗。 食物是当地的干酪和通常存放了一年之久的面包，人们就着劣酒吞下这种食物。山谷里常常没有小客栈，登山者只好随遇而安。有时同当地牧师 （他通常和他的教民一样穷）住在一起，有时同牧羊人或制乳酪的人住在一起。无论住在哪儿，情况都一样：肮脏、贫穷，极其不舒适。对于过惯了一顿饭吃7道菜、睡亚麻细布床单的人来说，变换一下生活环境来到阿尔卑斯山山区，那一定是很艰难的。 Lesson 4 Seeing hands能看见东西的手 Several cases have been reported
21、in Russia recently of people who can detect colours with their fingers, and even see through solid and walls. One case concerns and eleven-year-old schoolgirl, Vera Petrova, who has normal vision but who can also perceive things with different parts of her skin, and through solid walls. This ability
22、 was first noticed by her father. One day she came into his office and happened to put her hands on the door of a locked safe. Suddenly she asked her father why he kept so many old newspapers locked away there, and even described the way they were done up in bundles. Vera's curious
23、talent was brought to the notice of a scientific research institute in the town of Ulyanovsk, near where she lives, and in April she was given a series of tests by a special commission of the Ministry of Health of the Russian Federal Republic. During these tests she was able to read a newspaper thro
24、ugh an opaque screen and, stranger still, by moving her elbow over a child's game of Lotto she was able to describe the figures and colours printed on it; and, in another instance, wearing stockings and slippers, to make out with her foot the outlines and colours of a picture hidden under a carp
25、et. Other experiments showed that her knees and shoulders had a similar sensitivity. During all these tests Vera was blindfold; and, indeed, except when blindfold she lacked the ability to perceive things with her skin. It was also found that although she could perceive things with her fingers this
26、ability ceased the moment her hands were wet.参考译文 俄罗斯最近报导了几个事例，有人能用手指看书识字和辨认颜色，甚至能透过厚实的门和墙看到东西。 其中有一例谈到有一个名叫维拉.彼托洛娃的11岁学生。她的视力与常人一样，但她还能用皮肤的不同部位辨认东西，甚至看穿坚实的墙壁。是她父亲首先发现她这一功能的。一天，维拉走进父亲的办公室，偶然把手放在一个锁着的保险柜的门上，她突然问父亲为什么把这么多的旧报纸锁在柜子里，还说了报纸捆扎的情况。 维拉的特异功能引起了她家附近乌里扬诺夫斯克城一个科研单位的注意。4
27、月里，俄罗斯卫生部一个特别委员会对她进行了一系列的测试。在这些测试中，她能隔着不透明的屏幕读报纸。更为奇怪的是，她把肘部在儿童玩的“罗托”纸牌上移动一下，便能说出印在纸牌上的数字和颜色。还有一次，她穿着长筒袜子和拖鞋，能用脚步识别出藏在地毯下面的一幅画的轮廓和颜色。其他实验表明，她的膝盖和双肩有类似的感觉能力，在所有这些实验中，维拉的双眼都是蒙着的。如果不蒙上双眼她的皮肤就不再具有识别物体的能力。这是千真万确的。同时还发现，尽管她能用手指识别东西，但她的手一旦弄湿，这种功能便会立即消失。Lesson 5 Youth 青年 People are always
28、 talking about 'the problem of youth'. If there is one - which I take leave to doubt - then it is older people who create it, not the young themselves. Let us get down to fundamentals and agree that the young are after all human beings - people just like their elders. There is only one diffe
29、rence between an old man and a young one: the young man has a glorious future before him and the old one has a splendid future behind him: and maybe that is where the rub is. When I was a teenager, I felt that I was just young and uncertain - that I was a new boy in a huge school, and I
30、 would have been very pleased to be regarded as something so interesting as a problem. For one thing, being a problem gives you a certain identity, and that is one of the things the young are busily engaged in seeking. I find young people exciting. They have an air of freedom, and they
31、not a dreary commitment to mean ambitions or love of comfort. They are not anxious social climbers, and they have no devotion to material things. All this seems to me to link them with life, and the origins of things. It's as if they were, in some sense, cosmic beings in violent and lovely contr
32、ast with us suburban creatures. All that is in my mind when I meet a young person. He may be conceited, ill-mannered, presumptuous or fatuous, but I do not turn for protection to dreary cliches about respect of elders - as if mere age were a reason for respect. I accept that we are equals, and I wil
33、l argue with him, as an equal, if I think he is wrong.参考译文 人们总是在谈论“青年问题”。如果这个问题存在的话 - 请允许我对此持怀疑态度 - 那么，这个问题是由老年人而不是青年人造成的。让我们来认真研究一些基本事实：承认青年人和他们的长辈一样也是人。老年人和青年人只有一个区别：青年人有光辉灿烂的前景，而老年人的辉煌已成为过去。 问题的症结恐怕就在这里。 我十几岁时，总感到自己年轻，有些事拿不准 - 我是一所大学里的一名新生，如果我当时真的被看成像一个问题那样有趣，我会感到很得意的。因为
34、这至少使我得到了某种承认，这正是年轻人所热衷追求的。 我觉得年轻人令人振奋，无拘无束。他们既不追逐卑鄙的名利，也不贪图生活的舒适。他们不热衷于向上爬，也不一味追求物质享受。在我看来，所有这些使他们与生命和万物之源联系在了一起。从某种意义上讲，他们似乎是宇宙人，同我们这些凡夫俗子形成了强烈而鲜明的对照。每逢我遇到年轻人，脑子里就想到这些年轻人也许狂妄自负，举止无理，傲慢放肆，愚昧无知，但我不会用应当尊重长者这一套陈词滥调来为我自己辨护，似乎年长就是受人尊敬的理由。我认为我和他们是平等的。如果我认为他们错了，我就以平等的身份和他们争个明白。 Lesson 6
35、 The sporting spirit 体育的精神 I am always amazed when I hear people saying that sport creates goodwill between the nations, and that if only the common peoples of the would could meet one another at football or cricket, they would have no inclination to meet on the hattlefield.
36、Even if one didn't know from concrete examples (the 1936 Olympic Games, for instance) that international sporting contests lead to orgies of hatred, one could deduce if from general principles. Nearly all the sports practised nowadays are competitive. You play to win, and the game h
37、as little meaning unless you do your utmost to win. On the village green, where you pick up sides and no feeling of local patriotism is involved, it is possible to play simply for the fun and exercise: but as soon as a the question of prestige arises, as soon as you feel that you and some larger uni
38、t will be disgraced if you lose, the most savage combative instincts are aroused. Anyone who has played even in a school football match knows this. At the international level, sport is frankly mimic warfare. But the significant thing is not the behaviour of the players but the attitude of the specta
39、tors: and, behind the spectators, of the nations who work themselves into furies over these absurd contests, and seriously believe - at any rate for short periods - that running, jumping and kicking a ball are tests of national virtue.参考译文 当我听人们说体育运动可创造国家之间的友谊，还说各国民众若在足球场或板球场上交锋，就不愿在战场上
40、残杀的时候，我总是惊愕不已。一个人即使不能从具体的事例（例如1936年的奥林匹克运动会）了解到国际运动比赛会导致疯狂的仇恨，也可以从常理中推断出结论。 现在开展的体育运动几乎都是竞争性的。参加比赛就是为了取胜。如果不拚命去赢，比赛就没有什么意义了。 在乡间的草坪上，当你随意组成两个队，并且不涉及任何地方情绪时，那才可能是单纯的为了娱乐和锻炼而进行比赛。可是一量涉及到荣誉问题，一旦你想到你和某一团体会因为你输而丢脸时，那么最野蛮的争斗天性便会激发起来。即使是仅仅参加过学校足球赛的人也有种体会。在国际比赛中，体育简直是一场模拟战争。但是，要紧的还不是运动员的行为，而是观众
41、的态度，以及观众身后各个国家的态度。面对着这些荒唐的比赛，参赛的各个国家会如痴如狂，甚至煞有介事地相信 - 至少在短期内如此 - 跑跑、跳跳、踢踢球是对一个民族品德素质的检验。Lesson 7 Bats 蝙蝠Not all sounds made by animals serve as language, and we have only to turn to that extraordinary discovery of echo-location in bats to see a case in which the voice plays a strictly utilitar
42、ian role. To get a full appreciation of what this means we must turn first to some recent human inventions. Everyone knows that if he shouts in the vicinity of a wall or a mountainside, an echo will come back. The further off this solid obstruction, the longer time will elapse for the r
43、eturn of the echo. A sound made by tapping on the hull of a ship will be reflected from the sea bottom, and by measuring the time interval between the taps and the receipt of the echoes, the depth of the sea at that point can be calculated. So was born the echo-sounding apparatus, now in general use
44、 in ships. Every solid object will reflect a sound, varying according to the size and nature of the object. A shoal of fish will do this. So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish. With experience, and with improved apparatus, it is now possible no
45、t only to locate a shoal but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo. It has been found that certain bats emit squeaks and by receiving the echoes, they can locate and steer clear of obstacles - or locate flying insects on which they feed. Thi
46、s echo-location in bats is often compared with radar, the principle of which is similar.参考译文 动物发出的声音不都是用作语言交际。我们只要看一看蝙蝠回声定位这一极不寻常的发现，就可以探究一下声音在什么情况下有绝对的实用价值。 要透彻理解这句话的意义，我们应先回顾一下人类最近的几项发明。大家都知道，在墙壁或山腰附近发出的喊声，就会听到回声。固体障碍物越远。回声返回所用时间就越长。敲打船体所发了的声音会从海底传回来，测出回声间隔的时间，便可算出该处海洋的深度
47、。这样就产生了目前各种船舶上普遍应用的回声探测仪。任何固体者反射声音，反射的声音因物体的大小和性质的不同而不同。鱼群也反射声音。从测定海深到测定鱼群，这一进展比较容易。根据经验和改进了的仪器，不仅能够确定鱼群的位置，而且可以根据鱼群回声的特点分辨出是鲱鱼、鳕鱼，这是人们所熟悉的其他鱼。 人们发现，某些蝙蝠能发出尖叫声，并能通过回声来确定并躲开障碍物，或找到它们赖以为生的昆虫。蝙蝠这种回声定位常常可与雷达相比较，其原理是相似的。Lesson 8 Trading standards 贸易标准 Chickens slaughtered
48、in the United States, claim officials in Brussels, are not fit to grace European tables. No, say the American: our fowl are fine, we simply clean them in a different way. These days, it is differences in national regulations, far more than tariffs, that put sand in the wheels of trade between rich c
49、ountries. It is not just farmers who are complaining. An electric razor that meets the European Union's safety standards must be approved by American testers before it can be sold in the United States, and an American-made dialysis machine needs the EU's okay before is hits the market in Eur
50、ope. As it happens, a razor that is safe in Europe is unlikely to electrocute Americans. So, ask businesses on both sides of the Atlantic, why have two lots of tests where one would do? Politicians agree, in principle, so America and the EU have been trying to reach a deal which would e
51、liminate the need to double-test many products. They hope to finish in time for a trade summit between America and the EU on May 28TH. Although negotiators are optimistic, the details are complex enough that they may be hard-pressed to get a deal at all. Why? One difficulty is to construct the agreements. The Americans
