L13 Thames Waters

Oxford has been ruined by the motor industry. The peace which Oxford once knew, and which a great university city should always have, has been swept ruthlessly away; and no benefactions and research endowments can make up for the change in character which the city has suffered. At six in the morning the old courts shake to the roar of buses taking the next shift to Cowley and Pressed Steel, great lorries with a double deck cargo of cars for export lumber past Magdalen and the University Church. Loads of motor-engines are hurried hither and thither and the streets are thronged with a population which has no interest in learning and knows no studies beyond servo-systems and distributors, compression ratios and camshafts.

Theoretically the marriage of an old seat of learning and tradition with a new and wealthy industry might be expected to produce some interesting children. It might have been thought that the culture of the university would radiate out and transform the lives of the workers. That this has not happened may be the fault of the university, for at both Oxford and Cambridge the colleges tend to live in an era which is certainly not of the twentieth century, and upon a planet which bears little resemblance to the war-torn Earth. Wherever the fault may lie the fact remains that it is the theatre at Oxford and not at Cambridge which is on the verge of extinction, and the only fruit of the combination of

industry and the rarefied atmosphere of learning is the dust in the streets, and a pathetic sense of being lost which hangs over some of the colleges.

Lesson73 The way to King Street Last week Mrs. Mills went to London. She does not know London very well, and she lost her way. Suddenly, she saw a man near a bus-shop. “ I can ask him the way.” She said to herself. “Excuse me,” she said. “Can you tell me the way to King Street please” The man smiled pleasantly. He did not understand English! He spoke German. He was a tourist. Then he put his hand into his pocket, and took out a phrase-book. He opened the book and found a phrase. He read the phrase slowly. “I am sorry,” he said. “ I do not speak English.” Lesson 75 Uncomfortable shoes LADY : Have you any shoes like these SALESMAN: What size Lady: Size five. Salesman: What colour Lady: Black. Salesman: I’m sorry. We haven’t any. Lady: But my sister bought this pair last month. Salesman: Did she buy them here Lady: No, she bought them in the . Salesman: We had some shoes like those a month ago, but we haven’t any now. Lady: Can you get a pair for me please Salesman: I’m afraid that I can’t. They were in fashion last year and the year before last. But they’re not in fashion this year. Salesman: These shoes are in fashion now. Lady: They look very uncomfortable. Salesman: They are very uncomfortable. But women always wear uncomfortable shoes!

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. 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 so the tools of long ago have remained when even the bones of the men who made them have disappeared without trace. 【New words and expressions 生词和短语】 fossil man adj. 化石人 recount v. 叙述 saga n. 英雄故事 legend n. 传说,传奇 migration n. 迁移,移居 anthropologist n. 人类学家 archaeologist n. 考古学家

Lesson 40 Food and talk进餐与交谈 Was Mrs. Rumbold a good companion at dinner? Last week at a dinner party, the hostess asked me to sit next to Mrs. Rumbold. Mrs. Rumbold was a large, unsmiling lady in a tight black dress. She did not even look up when I took my seat beside her. Her eyes were fixed on her plate and in a short time, she was busy eating. I tried to make conversation. 'A new play is coming to "The Globe" soon,' I said. 'Will you be seeing it?' 'No,' she answered. 'Will you be spending your holidays abroad this year?' I asked. 'No,' she answered. 'Will you be staying in England?' I asked. 'No,' she answered. In despair, I asked her whether she was enjoying her dinner. 'Young man,' she answered, 'if you ate more and talked less, we would both enjoy our dinner!" 参考译文 在上星期的一次宴会上,女主人安排我坐在兰伯尔德夫人的身旁。兰伯尔德夫人是一位身材高大、表情严肃的女人,穿一件紧身的黑衣服。当我在她身旁坐下来的时候,她甚至连头都没有抬一下。她的眼睛盯着自己的盘子,不一会儿就忙着吃起来了。我试图找个话题和她聊聊。 “一出新剧要来‘环球剧场’上演了,”我说,“您去看吗?” “不,”她回答。 “您今年去国外度假吗?”我又问。 “不,”她回答。 “您就呆在英国吗?”我问。 “不,”她回答。 失望之中我问她饭是否吃得满意。 “年轻人,”她回答说,“如果你多吃点,少说点,我们两个都会吃得好的!” —、单词讲解New words and expressions host 1)n.待客的主人 hostess 女主人 the host nation 东道国,主办国 例: China is the host nation of the 2008 0lympic Games. 中国时2008奥运会的主办国。

新概念英语第四册原文翻译详细笔记

The modern city 现代城市 In the organization of industrial life the in?uence of the factory upon the physiological and mental state of the workers has been completely neglected. Modern industry is based on the conception of the maximum production at lowest cost, in order that an individual or a group of individuals may earn as much money as possible. It has expanded without any idea of the true nature of the human beings who run the machines, and without giving any consideration to the effects produced on the individuals and on their descendants by the arti?cial mode of existence imposed by the factory. The great cities have been built with no regard for us. The shape and dimensions of the skyscrapers depend entirely on the necessity of obtaining the maximum income per square foot of ground, and of offering to the tenants of?ces and apartments that please them. This caused the construction of gigantic buildings where too large masses of human beings are crowded together. Civilized men like such a way of living. While they enjoy the comfort and banal luxury of their dwelling, they do not realize that they are deprived of the necessities of life. The modern city consists of monstrous edi?ces and of dark, narrow streets full of petrol fumes and toxic gases, torn by the noise of the taxicabs, lorries and buses, and thronged ceaselessly by great crowds. Obviously, it has not been planned for the good of its inhabitants. ?一理理的 代 ?人造的?生存?方式隺加规模 I 平庸的 ?一倒夺巨?大的?大厦南满拥塞without any idea of 完全忽视without giving any consideration to
