全新版大学英语综合教程第二册第7单元课文详解篇1Part I Pre-Reading TaskListen to the recording two or three times and then think over the following questions:1. What is the passage about?2. What's your impression of the English language?3. Can you give one or two examples to illustrate(说明)the messiness of the English language?4. Can you guess what the texts in this unit are going to be about?The following words in the recording may be new to you:eggplantn. 茄子pineapplen. 菠萝hamburgern. 汉堡牛肉饼，汉堡包Part IITextSome languages resist the introduction of new words. Others, like English, seem to welcome them. Robert MacNeil looks at the history of English and comes to the conclusion that its tolerance for change represents deeply rooted ideas of freedom.THE GLORIOUS MESSINESS OF ENGLISHRobert MacNeilThe story of our English language is typically one of massive stealing from other languages. That is why English today has an estimated vocabulary of over one million words, while other major languages have far fewer.French, for example, has only about 75,000 words, and that includes English expressions like snack bar and hit parade. The French, however, do not like borrowing foreign words because they think it corrupts their language. The government tries to ban words from English and declares that walkman is not desirable; so they invent a word, balladeur, which French kids are supposed to say instead — but they don't.Walkman is fascinating because it isn't even English. Strictly speaking, it was invented by the Japanese manufacturers who put two simple English words together to name their product. That doesn't bother us, but it does bother the French. Such is the glorious messiness of English. That happy tolerance, that willingness to accept words from anywhere, explains the richness of English and why it has become, to a very real extent, the first truly globallanguage.How did the language of a small island off the coast of Europe become the language of the planet —more widely spoken and written than any other has ever been? The history of English is present in the first words a child learns about identity (I, me, you); possession (mine, yours); the body (eye, nose, mouth); size (tall, short); and necessities (food, water). These words all come from Old English or Anglo-Saxon English, the core of our language. Usually short and direct, these are words we still use today for the things that really matter to us.Great speakers often use Old English to arouse our emotions. For example, during World War II, Winston Churchill made thisspeech, stirring the courage of his people against Hitler's armies positioned to cross the English Channel: "We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills. We shall never surrender."Virtually every one of those words came from Old English, except the last — surrender, which came from Norman French. Churchill could have said, "We shall never give in," but it is one of the lovely — and powerful — opportunities of English that a writer can mix, for effect, different words from different backgrounds. Yet there is something direct to the heart that speaks to us from the earliest words in our language.When Julius Caesar invaded Britain in 55 B.C., English did not exist. The Celts, who inhabited the land, spoke languages that survive today mainly as Welsh. Where those languages came from is still a mystery, but there is a theory.Two centuries ago an English judge in India noticed that several words in Sanskrit closely resembled some words in Greek and Latin. A systematic study revealed that many modern languages descended from a commonparent language, lost to us because nothing was written down.Identifying similar words, linguists have come up with what they call an Indo-European parent language, spoken until 3500 to 2000 B.C. These people had common words for snow, bee and wolf but no word for sea. So some scholars assume they lived somewhere in north-central Europe, where it was cold. Traveling east, some established the languages of India and Pakistan, and others drifted west toward the gentler climates of Europe, Some who made the earliest move westward became known as the Celts, whom Caesar's armies found in Britain.New words came with the Germanic tribes — the Angles, the Saxons, etc. —that slipped across the North Sea to settle in Britain in the 5th century. Together they formed what we call Anglo-Saxon society.The Anglo-Saxons passed on to us their farming vocabulary, including sheep, ox, earth, wood, field and work. They must have also enjoyed themselves because they gave us the word laughter.The next big influence on English was Christianity. It enriched the Anglo-Saxon vocabulary with some 400 to 500 words from Greek and Latin, including angel, disciple and martyr.Then into this relatively peaceful land came the Vikings from Scandinavia. They also brought to English many words that begin with sk, like sky and skirt. But Old Norse and English both survived, and so you can rear a child (English) or raise a child (Norse). Other such pairs survive: wish and want, craft and skill, hide and skin. Each such addition gave English more richness, more variety.Another flood of new vocabulary occurred in 1066, when the Normans conquered England. The country now had three languages: French for the nobles, Latin for the churches and English for the common people. With three languages competing, there were sometimes different terms for the same thing. For example, Anglo-Saxons had the word kingly, but after the Normans, royal and sovereign entered the language as alternatives. The extraordinary thing was that French did not replace English. Over three centuries English gradually swallowed French, and by the end of the 15th century what had developed was a modified, greatly enriched language — Middle English —with about 10,000 "borrowed" French words.Around 1476 William Caxton set up a printing press inEngland and started a communications revolution. Printing brought into English the wealth of new thinking that sprang from the European Renaissance. Translations of Greek and Roman classics were poured onto the printed page, and with them thousands of Latin words like capsule and habitual, and Greek words like catastrophe and thermometer. Today we still borrow from Latin and Greek to name new inventions, like video, television and cyberspace.As settlers landed in North America and established the United States, English found itself with two sources — American and British. Scholars in Britain worried that the language was out of control, and some wanted to set up an academy to decide which words were proper and which were not. Fortunately their idea has never been put into practice.That tolerance for change also represents deeply rooted ideas of freedom. Danish scholar Otto Jespersen wrote in 1905, "The English language would not have been what it is if the English had not been for centuries great respecters of the liberties of each individual and if everybody had not been free to strike out new paths for himself."I like that idea. Consider that the same cultural soil producing the English language also nourished the great principles of freedom and rights of man in the modern world. The first shoots sprang up in England, and they grew stronger in America. The English-speaking peoples have defeated all efforts to build fences around their language.Indeed, the English language is not the special preserve of grammarians, language police, teachers, writers or the intellectual elite. English is, and always has been, the tongue of the common man.全新版大学英语综合教程第二册第7单元课文详解篇2 Robert MacNeil罗伯特·麦克尼尔Winston Churchill温斯顿·丘吉尔(1874 — 1965，英国政治家、首相)Hitler希特勒(1889 — 1945，纳粹德国元首)Julius Caesar尤利乌斯·凯撒(100 — 44BC，古罗马将军、政治家)Britain英国India印度Pakistan巴基斯坦Viking(8 — 10世纪时劫掠欧洲西北海岸的)北欧海盗Scandinavia斯堪的纳维亚England英格兰William Caxton威廉·卡克斯顿(英国印刷商、翻译家)Otto Jespersen奥托·叶斯柏森(1860 — 1943)全新版大学英语综合教程第二册第7单元课文详解篇31.

”人的一生就是不断学习、不断丰富和充实自己的过程。
青少年阶段，尤其是中学阶段，无疑是学习的最佳时期。
中学教育的重点应放在什么地方？美国著名科学家和科普作家萨根批评中学只抓各个学科具体内容的做法，他认为中学要注重对青少年的宏观教育，使他们建立起唯物的世界观和宇宙观，使他们能够正确对待自己，关心周围的世界——人类生存的环境和自己的地球同胞。
1 I attended junior and senior high school, public institutions in New Y ork and New Jersey, just after the Second World War. It seems a long time ago. The facilities and the skills of the teachers were probably well above average for the United States at that time. Since then, I've learned a great deal. One of the most important things I've learned is how much there is to learn, and how much I don't yet know. Sometimes I think how grateful I would be today if I had learned more back then about what really matters. In some respects that education was terribly narrow; the only thing I ever heard in school about Napoleon was that the United States made the Louisiana Purchase from him. (On a planet where some 95% of the inhabitants are not Americans, the only history that was thought worth teaching was American history. ) In spelling, grammar, the fundamentals of math, and other vital subjects, my teachers did a pretty good job. But there's so much else I wish they'd taught us.2 Perhaps all the deficiencies have since been rectified. It seems to me there are many things (often more a matter of attitude and perception than the simple memorization of facts) that the schools should teach —things that truly would be useful in later life, useful in making a stronger country and a better world, but useful also in making people happier. Human beings enjoy learning. That's one of the few things that we do better than the other species on our planet. Every student should regularly experience the "Aha!" —when something you never understood, or something you never knew was a mystery, becomes clear.3 So here's my list:Pick a difficult thing and learn it well.4 The Greek philosopher Socrates said this was one of the greatest of human joys,and it is. While you learn a little bit about many subjects, make sure you learn a great deal about one or two. It hardly matters what the subject is, as long as it deeply interests you, and you place it in its broader human context. After you teach yourself one subject, you become much more confident about your ability to teach yourself another. Y ou gradually find you've acquired a key skill. The world is changing so rapidly that you must continue to teach yourself throughout your life. But don't get trapped by the first subject that interests you, or the first thing you find yourself good at. The world is full of wonders, and some of them we don't discover until we're all grown up. Most of them, sadly, we never discover. Don't be afraid to ask "stupid" questions.5 Many apparently naive inquiries like why grass is green, or why the Sun is round, or why we need 55,000 nuclear weapons in the world —are really deep questions. The answers can be a gateway to real insights. It's also important to know, as well as you can, what it is that you don't know, and asking questions is the way. To ask "stupid" questions requires courage on the part of the asker and knowledge and patience on the part of the answerer. And don't confine your learning to schoolwork. Discuss ideas in depth with friends. It's much braver to ask questions even when there's a prospect ofridicule than to suppress your questions and become deadened to the world around you.Listen carefully.6 Many conversations are a kind of competition that rarely leads to discovery on either side. When people are talking, don't spend the time thinking about what you're going to say next. Instead, try to understand what they're saying, what experience is behind their remarks, what you can learn from or about them. Older people have grown up in a world very different from yours, one you may not know very well. They, and people from other parts of the country and from other nations, have important perspectives that can enrich your life.Everybody makes mistakes.7 Everybody's understanding is incomplete. Be open to correction, and learn to correct your own mistakes. The only embarrassment is in not learning from your mistakes.Know your planet.8 It's the only one we have. Learn how it works. We're changing the atmosphere, the surface, the waters of the Earth, often for some short-term advantage when the long-term implications are unknown. The citizens of any country should have at least something to say about the direction in which we're going. If we don't understand the issues, we abandon the future. Science and technology.9 Y ou can't know your planet unless you know something about science and technology. School science courses, I remember, concentrated on the unimportant parts of science, leaving the major insights almost untouched. The great discoveries in modern science are also great discoveries of the human spirit. For example, Copernicus showed that — far from being the center of the universe, about which the Sun, the Moon, the planets, and the stars revolved in clockwise homage — the Earth is just one of many small worlds. This is a deflation of our pretensions, to be sure, but it is also the opening up to our view of a vast and awesome universe. Every high school graduate should have some idea of the insights of Copernicus, Newton, Darwin, Freud, and Einstein. (Einstein's special theory of relativity, far from being obscure and exceptionally difficult, can be understood in its basics with no more than first-year algebra, and the notion of a rowboat in a river going upstream and downstream. )Don't spend your life watching TV.10 Y ou know what I'm talking about.Culture.11 Gain some exposure to the great works of literature, art and music. If such a work is hundreds or thousands of years old and is still admired, there is probably something to it. Like all deep experiences, it may take a little work on your part to discover what all the fuss is about. But once you make the effort, your life has changed; you've acquired a source of enjoyment and excitement for the rest of your days. In a world as tightly connected as ours is, don't restrict your attention to American or Western culture. Learn how and what people elsewhere think. Learn something of their history, their religion, their viewpoints.Compassion.12 Many people believe that we live in an extraordinarily selfish time. But there is a hollowness, a loneliness that comes from living only for yourself. Humans are capable of great mutual compassion, love, and tenderness. These feelings, however, need encouragement to grow.13 Look at the delight a one- or two-year-old takes in learning, and you see how powerful is the human will to learn. Our passion to understand the universe and our compassion for others jointly provide the chief hope for the human race. Lesson TwoIcons提起一位获得诺贝尔奖的华人物理学家的名字，今天的青少年恐怕很多人会感到陌生，无话可说，可是谈起当红歌星、球星，他们则是津津乐道。

We share the planet with thinking animals.(1)altogether (2)civilization (3)game (4)frightened (5)mammals(6)extinct (8)swept3.Today animal populations have sadly (dwindled) all over the world. In the last three centuries more than 200 species of (mammals) , birds, and reptiles have become extinct. Eight hundred more species are endangered. The (endangered species) includethe gorilla, the (orangutan) , the (7)giant tortoise, the trumpeter swan, (the whooping crane) , the big cats, and the whales. Since life began on this planet, countless creatures have come and gone - rendered extinct by natural changes. If extinction is part of the natural order, we can leave it as it is. Unfortunately, we cannot attribute the accelerating decline of our wild animals and plants to "natural" processes. Today's dangers to wildlife most often result from hunting, (habitat) degradation, environmental pollution, the introduction of (pesticides) , and expansion - all generally as a direct result of human activities. What man has done to the animals in the past hundred years will appall anyone who loves this world. It is very true that man's greatest "achievement" in the 20th century (9)is not that he traveled to the moon but that he destroyed forever an (heritage) that nature offered us.With each increase in man’s population, th e wilderness areas where the animals live get smaller. (10)The use of pesticides to control injurious insect also harms wild birds and animals. Water pollution kills fish in our rivers, lakes, and oceans. Hunters have almost exterminated (v.destroy utterly) many of the larger animals like the bighorn sheep (大角羊) and the grizzly bear (灰熊). And farmers destroy smaller animals like the prairie dog (草原犬鼠) and coyote(郊狼/小狼). (11)As a result of this （unrelenting）pressure, our wildlife is disappearing at the rate of one species or subspecies per years.In Scotland, safari-park wardens answer their phones to hear the heavy breathing of Chippy the chimpanzee. The chimp had pressed the right buttons to dial preprogrammed numbers on a cell phone he'd swiped from a keeper.It doesn't take a rocket scientist to know that animals are smart. But do animals really think? And if so, are their thoughts similar to ours? Scientists have long tried to figure out the intricate workings of human intelligence, but the process of how a thought is chemically produced in the brain still remains a mystery. Researchers do know that humans rank high on the "smart meter" because of our abilities to use complex language and express abstract ideas. Now ethologists (animal behavior scientists) look for clear signs of intelligence in other animals, starting with three top categories:* emotions: Chimps react to dramatic TV scenes starring other chimps, which suggests they recognize and express emotions.* self-recognition: Bottlenose dolphins and chimpanzees recognize themselves in mirrors, which suggests they're aware of themselves as individuals. So far, only primates (humans and apes) and dolphins display this ability.* language: New research shows that prairie dogs use descriptive chirps to inform their colonies about predators and intruders--a human's size, for example, the colors he wears, how fast he's moving, even whether he's carrying a gun.Not long ago, many scientists ranked humans as the smartest animals and all other creatures inferior. Others relied on anthropomorphism, or testing animals purely by human attributes. Today's studies show that animals solve problems, make decisions, and show emotions--not unlike humans. "We share the planet with thinking animals," says Harvard ethologist Marc Hauser.。

• The Virtues of Aging by Jimmy Carter • "We are not alone in our worry about both the physical aspect of aging and the prejudice that exists toward the elderly, which is similar to racism or sexism. What makes it different is that the prejudice also exists among those of us who are either within this group or rapidly approaching it.
• The husband says, "What are you talking about? We're lying here in bed together talking to one another." She says, "No, I'm definitely dead." He insists, "You're not dead. What in the world makes you think you're dead?" "Because I woke up this morning and nothing hurts."
