Lesson1 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 world where even now people cannot write. The only way that they can preserve their history is to recount it as sagas--legends handed down from one generation of story-tellers to 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 Pacific 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 help them to find out where the first 'modern men' came from.

新概念英语第四册课文:Lesson4 【课文】 First listen and then answer the following question. 听录音,然后回答以下问题。 How did Vera discover she had this gift of second sight? Several cases have been reported in Russia recently of people who can read and detect colours with their fingers, and even see through solid doors and walls. One case concerns an 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 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 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 through 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 carpet. Other experiments showed that her knees and

最新新概念第四册Lesson46~48课文翻译及学习笔记

新概念第四册Lesson46课文翻译及学习笔记 【课文】 First listen and then answer the following question. 听录音,然后回答以下问题。 Who, according to the author, are 'Fortune's favoured children'? A gifted American psychologist has said, 'Worry is a spasm of the emotion; the mind catches hold of something and will not let it go.' It is useless to argue with the mind in this condition. The stronger the will, the more futile the task. One can only gently insinuate something else into its convulsive grasp. And if this something else is rightly chosen, if it really attended by the illumination of another field of interest, gradually, and often quite swiftly, the old undue grip relaxes and the process of recuperation and repair begins. The cultivation of a hobby and new forms of interest is therefore a policy of the first importance to a public man. But this is not a business that can be undertaken in a day or swiftly improvised by a mere command of the will. The growth of alternative mental interests is a long process. The seeds must be carefully chosen; they must fall on good ground; they must be sedulously tended, if the vivifying fruits are to be at hand when needed. To be really happy and really safe, one ought to have at least two or three hobbies, and they must all be real. It is no use starting late in life to say: 'I will take an interest in this or that.' Such an attempt only aggravates the strain of mental effort. A man may acquire great knowledge of topics unconnected with his daily work, and yet get hardly any benefit or relief. It is no use doing what you like; you have got to like what you do. Broadly speaking, human beings may be divided into three classes: those who are toiled to death, those who are worried to death, and those who are bored to death. It is no use offering the manual labourer, tired out with a hard week's sweat and effort, the chance of playing a game of football or baseball or Saturday afternoon. It is no use inviting the politician or the professional or business man, who has been working or worrying about serious things for six days, to work or worry about trifling things at the weekend. As for the unfortunate people who can command everything they want, who can gratify every caprice and lay their hands on almost every object

`课文1 发现化石人 1. We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. 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。 2. But there are some parts of the world where even now people cannot write. 但直到现在,世界上有些地方,人们还不会书写。 3. The only way that they can preserve their history is to recount it as sagas -- legends handed down from one generation of story tales to another. 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。 4. These legends are useful because they can tell us something about migrations of people who lived long ago, 这些传说是有用的,因为他们告诉我们很久以前生活在这里的移民的一些事情。 5. but none could write down what they did. 但是没有人能写下来。 6. Anthropologists wondered where the remote ancestors of the Polynesian peoples now living in the Pacific Islands came from. 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, 7. The sagas of these people explain that some of them came from Indonesia about 2,000 years ago. 当地人的传说却告诉人们:其中一部分是约在2,000年前从印度尼西亚迁来的。 8. But the first people who were like ourselves lived so long ago that even their sagas,if they had any, are forgotten. 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。 9. So archaeologists have neither history nor legends to help them to find out where the first 'modern men' came from. 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。 10. Fortunately, however, ancient men made tools of stone, especially flint, 然而,幸运的是,远古人用石头制作了工具,特别是用燧石, 11. because this is easier to shape than other kinds. 因为燧石较之其他石头更容易成形。 12. They may also have used wood and skins, but these have rotted away. 他们也可能用过木头和兽皮,但这类东西早已腐烂殆尽。 13. Stone does not decay, and so the tools of long ago have remained when even the bones of the men who made them have disappeared without trace. 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。 $课文2 不要伤害蜘蛛 14. Why, you may wonder, should spiders be our friends? 你可能会觉得奇怪,蜘蛛怎么会是我们的朋友呢? 15. Because they destroy so many insects, and insects include some of the greatest enemies of the human race. 因为它们能消灭那么多的昆虫,其中包括一些人类的大敌, 16. Insects would make it impossible for us to live in the world; 昆虫就会使我们无法在地球上生活下去, 17. they would devour all our crops and kill our flocks and herds, 昆虫会吞食我们的全部庄稼,杀死我们的成群的牛羊。 18. if it were not for the protection we get from insect-eating animals. 要不是人类受一些食虫动物的保护, 19. 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 dest royed by spiders. 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。 20. Moreover, unlike some of the other insect eaters, spiders never do the harm to us or our belongings. 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。 21. Spiders are not insects, as many people think, nor even nearly related to them. 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。 22. One can tell the difference almost at a glance, 人们几乎一眼就能看出二者的差异, 23. for a spider always has eight legs and insect never more than six. 因为蜘蛛都是8条腿,而昆虫的腿从不超过6条。 24. How many spiders are engaged in this work no our behalf? 有多少蜘蛛在为我们效力呢? 25. One authority on spiders made a census of the spiders in grass field in the south of England, 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。 26. and he estimated that there were more than 2,250,000 in one acre; 他估计每英亩草坪里有225万多只蜘蛛。 27. that is something like 6,000,000 spiders of different kinds on a football pitch. 这就是说,在一个足球场上约有600万只不同种类的蜘蛛。 28. Spiders are busy for at least half the year in killing insects. 蜘蛛至少有半年在忙于吃昆虫。 29. It is impossible to make more than the wildest guess at how many they kill, 它们一年中消灭了多少昆虫,我们简直无法猜测, 30. but they are hungry creatures, not content with only three meals a day. 它们是吃不饱的动物,不满意一日三餐。 31. 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. 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。 $课文3 马特霍恩山区人 32.

新概念英语第四册第十一单元课文原文

新概念英语第四册第十一单元课文原文 Lesson 11 How to grow old 如何安度晚年 Some old people are oppressed by the fear of death. In the young there is a justification for this feeling. Young men who have reason to fear that they will be killed in battle may justifiably feel bitter in the thought that they have been cheated of the best things that life has to offer. But in an old man who has known human joys and sorrows, and has achieved whatever work it was in him to do, the fear of death is somewhat abject and ignoble. The best way to overcome it so at least it seems to me----is to make your interests gradually wider and more impersonal, until bit by bit the walls of the ego recede, and your life becomes increasingly merged in the universal life. An individual human existence should be like a river--small at first, narrowly contained within its banks, and rushing passionately past boulders and over waterfalls. Gradually the river grows wider, the banks recede, the waters flow more quietly, and in the end, without any visible break, they become merged in the sea, and painlessly lose their individual being. The man who, in old age, can see his life in this way, will not suffer from the fear of death, since the things he cares for will continue. And it, with the decay of vitality, weariness increases, the thought of rest will be not unwelcome. I should wish to die while still at work, knowing that others will carry on what I can no longer do, and content in the thought that what was possible has been done. (NCE Book Four)
