大学英语自学教程下册课文翻译及答案
Unit 1第一部分 Text A【课文译文】什么是决策?决策是从可供挑选的行动方案中作出选择,目的在于确定并实现组织机构的目标或目的。
之所以要决策是因为存在问题,或是目标或目的不对,或某种东西妨碍目标或目的实现。
因此,决策过程对于管理人员非常重要。
管理者所做的一切几乎都与决策有关,事实上,有人甚至认为管理过程就是决策过程。
虽然决策者不能预测未来,但他们的许多决策要求他们必须考虑未来可能会发生的情况。
管理者必须对未来的事情作出最佳的猜测,并使偶然性尽可能少地发生。
但因为总是存在着未知情况,所以决策往往伴随着风险。
有时失误的决策带来的后果不很严重,但有时就会不堪设想。
选择就是从多种选项中进行取舍,没有选择,就没有决策。
决策本身就是一个选择的过程,许多决策有着很广的选择范围。
例如,学生为了实现自己获得学位的目标,可能会从多门课程中进行选择,对于管理者来说,每一个决策都受到政策、程序、法律、惯例等方面的制约,这些制约存在于一个组织的各个部门里。
选项就是可供选择的种种可行的行动方案。
没有选项,就没有选择,因而也就没有决策。
如果看不到任何选项,这意味着还没有对问题进行彻底的研究。
例如,管理者有时会用“非此即彼”的方式处理问题,这是他们简化问题的方法。
这种简化问题的习惯常常使他们看不到其他的选项。
在管理这个层次上,制定决策包括:识别选项和缩小选项范围,其范围小到微乎其微,大到近乎无限。
决策者必须有某种方法来断定几种选项中的最佳选项,即哪个选项最有利于实现其组织的目标。
组织的目标是指该组织努力完成或达到的目标或现状。
由于个人(或组织)对于怎样实现其目标的方式都有不同的见解,最佳的选择就在于决策者了。
常常是一个组织的下属部门做出的决策对自己有利,而对上一级的部门来说,就不是较佳选择了。
这种增加部门的局部利益而减少其他部门的局部利益所作出的权衡,叫做局部优化。
例如,市场营销经理为增加广告预算可能会讲得头头是道,但从更大的布局来看,增加优化产品的研究经费也许对组织更有利。
大学英语自学教程(上册)课后答案及释义UNIT3
第一部分 Text A【课文译文】大 西 洋大西洋是将欧洲和美洲分隔开的海洋之一。
它使南北美洲长达几个世纪之久都未被人发现。
人们对大西洋有许多误解,这使得早期的海员不愿意远航驶入大西洋。
一种想法是大西洋远抵“世界的边缘”,海员们担心他们会一直航行到地球边上掉落下去。
另一个想法是在赤道处,大西洋的海水是滚烫的。
大西洋的面积只是太平洋的一半,但也非常辽阔。
哥伦布穿越过的地方宽达4000多英里(6000公里)。
即使最窄的地方宽度也有大约2000英里(3200公里),这是一片位于南美洲最东端与非洲最西端之间的水域。
大西洋有两点非同寻常。
其一是在如此辽阔的海洋里少有岛屿。
另外,大西洋是世界上含盐量最高的海洋。
大西洋海水量很大,人们无法想像到底有多少水。
但如果假设不再有降雨和河水注入,则需4000年大西洋才会干涸。
大西洋平均水深有2英里(3.2公里)多一点,但有些地方要深得多。
最深处在波多黎各岛附近,深达30246英尺——约6英里(9.6公里)。
世界上最长的山脉之一从大西洋海底隆起,这条山脉沿海底中部向南北延伸,几座山峰露出海面,形成岛屿。
亚速尔群岛就是大西洋中部山脉露出水面的几座山峰。
佛罗里达州向东几百英里有一处海域叫马尾藻海,这里由于很少刮风,海面很平静。
在使用帆船的时代,船员们担心他们会因无风而在此处无法航行。
有时他们确实会遇到这种情况。
海流有时被称作“海洋中的河流”。
大西洋有一条这种“河流”,叫做墨西哥湾流,这是一股暖水流;另外一条是拉布拉多海流——这是来自北冰洋的冷水流。
洋流对流域附近大陆的气候有影响。
大西洋为两岸的人们提供了丰富的食物。
大浅滩是最著名的捕鱼区之一,位于纽芬兰附近。
今天,大西洋是一条重要的航路,这条航路并不总是风平浪静,毫无危险。
暴风雨会掠过洋面,堆起大浪。
从北冰洋漂来的冰山也会横穿航道。
我们现在有快捷的旅行方式,这个大洋似乎也变小了。
哥伦布横越大西洋用了两个多月的时间,一艘现代化快轮不到4天就可完成这一航程,而乘飞机从纽约到伦敦只用8小时,从南美到非洲只用4小时。

How to be a successful language learner?“Learning a language is easy, even a child can do it!”Most adults who are learning a second language would disagree with this statement. For them, learning a language is a very difficult task. They need hundreds of hours of study and practice, and even this will not guarantee success for every adult language learner.Language learning is different from other kinds of learning. Some people who are very intelligent and successful in their fields find it difficult to succeed in language learning. Conversely, some people who are successful language learners find it difficult to succeed in other fields.Language teachers often offer advice to language learners: “Read as mu ch as you can in the new language.”“ Practice speaking the language everyday. ”“Live with people who speak the language.”“Don’ttranslate-tryto think in the new language.”“ Learn as a child would learn; play withthe language.”But what does a successful language learner do? Language learning research shows that successful language learners are similar in many ways.First of all, successful language learners are independent learners. They do not depend on the book or the teacher; they discover their own way to learn the language. Instead of waiting for the teacher to explain, they try to find the patterns and the rules for themselves. They are good guessers who look for clues and form their own conclusions. When they guess wrong, they guess again. They try to learn from their mistakes.Successful language learning is active learning. Therefore,successful learners do not wait for a chance to use the language; they look for such a chance. They find people who speak the language and they ask these people to correct them when they make a mistake. They will try anything to communicate. They are not afraid to repeat what they hear or to say strange things; they are willing to make mistakes and try again. When communication is difficult, they can accept information that is inexact or incomplete. It is more important for them to learn to thinkin the language than to know the meaning of every word.Finally, successful language learners are learners with a purpose. They want to learn the language because they are interested in the language and the people who speak it. It is necessary for them to learn the language in order to communicate with these people and to learn fromthem. They find it easy to practice using the language regularly because they want to learn with it.What kind of language learner are you? If you are a successful language learner, you have probably been learning independently, actively, and purposefully. On the other hand, if your language learning has been less than successful, you might do well to try some of the techniques outlined above.01-B. LanguageWhen we want to tell other people what we think, we can do it notonly with the help of words, but also in many other ways. For instance, we sometimes move our heads up and down when we want to say "yes” and we moveour heads from side to side when we want to say "no." People who can neither hear nor speak (that is, deaf and dumb people) talk to eachother with the help of their fingers. People who do not understand each other's language have to do the same. The following story shows how they sometimes do it.An Englishman who could not speak Italian was once traveling inItaly. One day he entered a restaurant and sat down at a table. When the waiter came, the Englishman opened his mouth, put his fingers in it,took them out again and moved his lips. In this way he meant to say, "Bring me something to eat." The waiter soon brought him a cup of tea. The Englishman shook his head and the waiter understood that he didn't want tea, so he took it away and brought him some coffee. The Englishman,who was very hungry by this time and not at all thirsty, looked very sad. He shook his head each time the waiter brought him something to drink. The waiter brought him wine, then beer, then soda-water, but thatwasn’t food, of course.He was just going to leave the restaurant when another traveler came in. When this man saw the waiter, he put his hands on his stomach. That was enough: in a few minutes there was a large plate of macaroni and meat on the table before him.As you see, the primitive language of signs is not always very clear. The language of words is much more exact.Words consist of sounds, but there are many sounds which have a meaning and yet are not words. For example, we may say "Sh-sh-sh” when we mean"keep silent.” When babies laugh, we know they are happy, and when they cry, we know they are ill or simply want something.It is the same with animals. When a dog says “G-r-r” or a cat says "F-f-f” we know they are angry.But these sounds are not language. Language consists of words which we put together into sentences. But animals can not do this: a dog can say “G-r-r” when he means "I am angry,” but he cannot say first "I” andthen "am” and then "angry.” A parrot can talk like a m an; it can repeatwhole sentences and knows what they mean. We may say that a parrot talks, but cannot say that it really speaks, because it cannot form new sentences out of the words it knows. Only man has the power to do this.02-A. Taxes, Taxes, and More TaxesAmericans often say that there are only two things a person can be sure of in life: death and taxes, Americans do not have a corner on the "death" market, but many people feel that the United States leadsthe world with the worst taxes.Taxes consist of the money which people pay to support their government. There are generally three levels of government in the United States: federal, state, and city; therefore, there are three types of taxes.Salaried people who earn more than a few thousand dollars must pay a certain percentage of their salaries to the federal government. The percentage varies from person to person. It depends on their salaries. The federal government has a graduated income tax, that is, the percentage of the tax (14 to 70 percent) increases as a person's income increases. With the high cost of taxes, people are not very happy on April 15, when the federal taxes are due.The second tax is for the state government: New York, California, North Dakota, or any of the other forty-seven states. Some states have an income tax similar to that of the federal government. Of course, the percentage for the state tax is lower. Other states have a sales tax, which is a percentage charged to any item which you buy in that state.For example, a person might want to buy a packet of cigarettes for twenty-five cents. If there is a sales tax of eight percent in that state, then the cost of the cigarettes is twenty-seven cents. Thisfigure includes the sales tax. Some states use income tax in addition to sales tax to raise their revenues. The state tax laws are diverse and confusing.The third tax is for the city. This tax comes in two forms: property tax (people who own a home have to pay taxes on it) and excise tax, which is charged on cars in a city. The cities use these funds for education, police and fire departments, public works and municipal buildings.Since Americans pay such high taxes, they often feel that they are working one day each week just to pay their taxes. People always complain about taxes. They often protest that the government uses their tax dollars in the wrong way. They say that it spends too much on useless and impractical programs. Although Americans have different views on many issues, they tend to agree on one subject: taxes are too high.02-B. AdvertisingAdvertising is only part of the total sales effort, but it is the part that attracts the most attention. This is natural enough because advertising is designed for just that purpose. In newspapers, in magazines, in the mail, on radio and television, we constantly see and hear the messages for hundreds of different products and services. Forthe most part, they are the kinds of things that we can be persuaded to buy – foodand drinks, cars and television sets, furniture and clothing, travel and leisure time activities.The simplest kind of advertising is the classified ad. Every day the newspapers carry a few pages of these ads; in the large Sundayeditions there may be several sections of them. A classified ad is usually only a few lines long. It is really a notice or announcementthat something is available.Newspapers also carry a large amount of display advertising. Most of it is for stores or for various forms of entertainment. Newspapers generally reach an audience only in a limited area. To bring their message to a larger audience, many who want to put out their ads use national magazines. Many of the techniques of modern advertising were developed in magazine ads. The use of bright colors, attractive pictures, and short messages is all characteristic of magazine ads. The most important purpose is to catch the eye. The message itself is usually short, often no more than a slogan which the public identifies with the product.The same techniques have been carried over into television advertising. Voices and music have been added to color and pictures to catch the ear as well as the eye. Television ads are short –usuallyonly 15,30,or 60 seconds, but they are repeated over and over again so that the audience sees and hears them many times. Commercial television has mixed entertainment and advertising. If you want the entertainment, you haveto put up with the advertising-and millions of people want the entertainment.The men and women in the sales department are responsible for the company’s advertising, They must decide on the audience they want to reach. They must also decide on the best way to get their message totheir particular audience. They also make an estimate of the costsbefore management approves the plan. In most large companies management is directly involved in planning the advertising.03-A. The Atlantic OceanThe Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the Americas from being discoveredby the people of Europe.Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to "the edge of the world." Sailors were afraid that they might sail right off the earth. Another idea was that at the equator the ocean would be boiling hot.The Atlantic Ocean is only half as big as the Pacific, but it isstill very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2, 000 miles(3,200 km) wide. This narrowest place is between the bulge of south America and the bulge of Africa.Two things make the Atlantic Ocean rather unusual. For so large an ocean it has very few islands. Also, it is the world's saltiest ocean.There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into it and no more water wasbrought to it by rivers. It would take the ocean about 4,000 yearsto dry up. On the average the water is a little more than two miles (3.2 km) deep, but in places it is much deeper. The deepest spot is near Puerto Rico. This "deep" 30, 246 feet - almost six miles (9.6 km).One of the longest mountain ranges of the world rises the floor of the Atlantic. This mountain range runs north and south down the middle of the ocean. The tops of a few of the mountains reach up above the sea and make islands. The Azores are the tops of peaks in the mid-Atlantic mountain range.Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels the crew were afraid they would be becalmed here. Sometimes they were.Ocean currents are sometime called "rivers in the sea." One of these "river" in the Atlantic is called the Gulf Stream. It is a current of warm water. Another is the Labrador Current - cold water coming down from theArctic. Ocean currents affect the climates of the lands near which they flow.The Atlantic furnishes much food for the people on its shores. Oneof its most famous fishing regions, the Grand Banks, is near Newfoundland.Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships.We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it.A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!03-B. The MoonWe find that the moon is about 239,000 miles (384,551km) away fromthe earth, and, to within a few thousand miles, its distance always remains the same. Yet a very little observation shows that the moon is not standing still. Its distance from the earth remains the same, butits direction continually changes. We find that it is traveling in a circle - or very nearly a circle - round the earth, going completely round once a month, or, more exactly, once every 27 1/3 days. It is our nearest neighbour in space, and like ourselves it is kept tied to the earth by the earth's gravitational pull.Except for the sun, the moon looks the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is sonear to us. Its diameter is only 2, 160 miles (3,389 km), or a little more than a quarter of the diameter of the earth.Once a month, or, more exactly, once every 29 1/2 days, at the time we call "full moon," its whole disc looks bright. At other timesonly part of it appears bright, and we always find that this is the part which faces towards the sun, while the part facing away from the sun appears dark. Artists could make their pictures better if they kept in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It merely reflects the light of the sun, like a huge mirror hung in the sky.Yet the dark part of the moon’s surface is not absolutely black;generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. we knows well how the surface of the sea or of snow, or even of a wet road, may reflect uncomfortably much of the sun's light on to our faces. In the same way the surface of the whole earth reflects enough of the sun's light on to the face of the moon for us to be ableto see the parts of it which would otherwise be dark.If there were any inhabitants of the moon, they would see our earth reflecting the light of the sun, again like a huge mirror hung in the sky. They would speak of earthlight just as we speak of moonlight. "The old moon in the new moon's arms" is nothing but that part of the moon's surface on which it is night, lighted up by earth light. In the same way,the lunar inhabitants would occasionally see part of our earth in full sunlight, and the rest lighted only by moonlight; they might call this "the old earth in the new earth's arms.”04-A. Improving Your MemoryPsychological research has focused on a number of basic principles that help memory: meaningfulness, organization, association, and visualization. It is useful to know how these principles work.Meaningfulness affects memory at all levels. Information that doesnot make any sense to you is difficult to remember. There are several ways in which we can make material more meaningful. Many people, for instance, learn a rhyme to help them remember. Do you know the rhyme “Thirty dayshas September, April, June, and November…? ” It helps many people remember which months of the year have 30 days.Organization also makes a difference in our ability to remember. How useful would a library be if the books were kept in random order? Material that is organized is better remembered than jumbled information. One example of organization is chunking. Chunking consists of grouping separate bits of information. For example, the number 4671363 is more easily remembered if it is chunked as 467,13,63. Categorizing is another means of organization. Suppose you are asked to remember the followinglist of words: man, bench, dog, desk, woman, horse, child, cat, chair. Many people will group the words into similar categories and remember them asfollows: man, woman, child; cat, dog, horse; bench, chair, desk. Needless to say, the second list can be remembered more easily than the first one.Association refers to taking the material we want to remember and relating it to something we remember accurately. In memorizing a number, you might try to associate it with familiar numbers or events. For example, the height of Mount Fuji in Japan - 12, 389 feet - might be remembered using the following associations: 12 is the number of months in the year, and 389 is the number of days in a year(365) added to the number of months twice (24).The last principle is visualization. Research has shown striking improvements in many types of memory tasks when people are asked to visualize the items to be remembered. In one study, subjects in one group were asked to learn some words using imagery, while the second group used repetition to learn the words. Those using imagery remembered 80 to 90 percent of the words, compared with 30 to 40 percent of the words for those who memorized by repetition. Thus forming an integrated image with all the information placed in a single mental picture can help us to preserve a memory.04-B. Short-term MemoryThere are two kinds of memory: shore-term and long-term. Information in long-term memory can be recalled at a later time when it is needed. The information may be kept for days or weeks. Sometimes information in the long-term memory is hard to remember. Students taking exam oftenhave this experience. In contrast[zzg1], information in shore-term memory is kept for only a few seconds, usually by repeating the information over and over. For example, you look up a number in the telephone book, and before you dial, you repeat the number over and over. If someone interrupts you, you will probably forget the number. In laboratory studies, subjects are unable to remember three letters after eighteen seconds if they are not allowed to repeat the letters to themselves.Psychologists study memory and learning with both animal and human subjects. The two experiments here show how short-term memory has been studied.Dr. Hunter studied short-term memory in rats. He used a special apparatus which had a cage for the rat and three doors, There was alight in each door. First the rat was placed in the closed cage. Next, one of the lights was turned on and then off. There was food for the rat only at this door. After the light was turned off, the rat had to wait a short time before it was released from its cage. Then, if it went to the correct door, it was rewarded with the food that was there. Hunter did this experiment many times. He always turned on the lights in a random order. The rat had to wait different intervals before it was released from the cage. Hunterfound that if the rat had to wait more than ten seconds, it couldnot remember the correct door. Hunter's results show that rats have a short-term memory of about ten seconds.Later, Dr. Henning studied how students who are learning English as a second language remember vocabulary. The subjects in his experiment were 75 students at the University of California in Los Angeles. They represented all levels of ability in English; beginning, intermediate, advanced, and native-speaking students.To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered. Each question had four choices. The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words that sound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning. Some of them had four unrelated choices. For instance, weather, method, love, and result could be used as four unrelated words. Finally the subjects took a language proficiency test.Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning’s results suggest that beginning students hold the sound of words in their short-term memory, while advanced students hold the meaning of words in their short-term memory.05-A. Fallacies about FoodMany primitive peoples believed that by eating an animal they couldget some of the good qualities of that animal for themselves. They thought, for example, that eating deer would make them run as fast asthe deer. Some savage tribes believed that eating enemies that had shown bravery in battle would make them brave. Man-eating may have started because people were eager to become as strong and brave as their enemies.Among civilized people it was once thought that ginger root by some magical power could improve the memory. Eggs were thought to make the voice pretty. Tomatoes also were believed to have magical powers. They were called love apples and were supposed to make people who ate themfall in love.Later another wrong idea about tomatoes grew up - the idea that they were poisonous. How surprised the people who thought tomatoes poisonous would be if they could know that millions of pounds of tomatoes were supplied to soldiers overseas during World War II.Even today there are a great many wrong ideas about food. Some ofthem are very widespread.One such idea is that fish is the best brain food. Fish is goodbrain food just as it is good muscle food and skin food and bone food.But no one has been able to prove that fish is any better for the brain than many other kinds of food.Another such idea is that you should not drink water with meals. Washing food down with water as a substitute for chewing is not a goodidea, but some water with meals has been found to be helpful. It makes the digestive juices flow more freely and helps to digest the food.Many of the ideas which scientists tell us have no foundation haveto do with mixtures of foods. A few years ago the belief became general that orange juice and milk should never be drunk at the same meal. The reason given was that the acid in the orange juice would make the milk curdle and become indigestible. As a matter of fact, milk always meetsin the stomach a digestive juice which curdles it; the curdling of the milk is the first step in its digestion. A similar wrong idea is that fish and ice cream when eaten at the same meal form a poisonous combination.Still another wrong idea about mixing foods is that proteins and carbohydrates should never be eaten at the same meal. Many people think of bread, for example, as a carbohydrate food. It is chiefly a carbohydrate food, but it also contains proteins. In the same way, milk, probably the best single food, contains both proteins and carbohydrates. It is just as foolish to say that one should never eat meat and potatoes together as it is to say that one should never eat bread or drink milk.05-B. Do Animals Think?The question has often been asked, Do animals think? I believe that some of them think a great deal. Many of them are like children in their sports. We notice this to be true very often with dogs and cats; but it is true with other animals as well.Some birds are very lively in their sports; and the same is truewith some insects. The ants, hardworking as they are, have their times for play. They run races; they wrestle; and sometimes they have mock fights together. Very busy must be their thoughts while engaged in these sports.There are many animals, however, that never play; their thoughts seem to be of the more sober kind. We never see frogs engaged in sport. They all the time appear to be very grave. The same is true of the owl, who always looks as if he were considering some important question.Animals think much while building their houses. The bird searchesfor what it can use in building its nest, and in doing this it thinks. The beavers think as they build their dams and their houses. They think in getting their materials, and also in arranging them, and inplastering themtogether with mud. Some spiders build houses which could scarcely have been made except by some thinking creature.As animals think, they learn. Some learn more than others. Theparrot learns to talk, though in some other respects it is quite stupid. The mocking bird learns to imitate a great many different sounds. The horse is not long in learning many things connected with the work which he has to do. The shepherd dog does not know as much about most things as some other dogs , and yet he understands very well how to take care of sheep.Though animals think and learn, they do not make any real improvement in their ways of doing things, as men do. Each kind of bird has its own way of building a nest, and it is always the same way. Andso of other animals. They have no new fashions, and learn none from each other. But men, as you know, are always finding new ways of building houses, and improved methods of doing almost all kinds of labor.Many of the things that animals know how to do they seem to knoweither without learning, or in some way which we cannot understand. They are said to do such things by instinct; but no one can tell whatinstinct is. It is by this instinct that birds build their nests and beavers their dam and huts. If these things were all planned and thought out just as men plan new houses. there would be some changes in the fashions of them, and some improvements.I have spoken of the building instinct of beavers. An English gentleman caught a young one and put him at first in a cage. After a while he let him out in a room where there was a great variety of things. As soon as he was let out he began to exercise his building instinct. He gathered together whatever he could find, brushes, baskets, boots, clothes, sticks, bits of coal, etc., and arranged them as if to build a dam. Now, if he had had his wits about him, he would have known that there was no use in building a dam where there was no water.It is plain that, while animals learn about things by their sensesas we do, they do not think nearly as much about what they learn, andthis is the reason why they do not improve more rapidly. Even the wisestof them, as the elephant and the dog, do not think very much about what they see and hear. Nor is this all. There are some thing that we understand, but about which animals know nothing. They have no knowledge of anything that happens outside of their own observation. Their minds are so much unlike ours that they do not know the difference betweenright and wrong.06-A. DiamondsDiamonds are rare, beautiful, and also quite useful. They are the hardest substance found in nature. That means a diamond can cut anyother surface. And only another diamond can make a slight cut in a diamond.Diamonds are made from carbon. Carbon is found in all living things, both plant and animal. Much of the carbon in the earth comes from things that once lived.Scientists know that the combination of extreme heat and pressure changes carbon into diamonds. Such heat and pressure exist only in the hot, liquid mass of molten rock deep inside the earth. It is thoughtthat millions of years ago this liquid mass pushed upward through cracks in the earth’s crust. As the liquid cooled, the carbon changed into diamond crystals.There are only four areas where very many diamonds have been found.The first known area was in India, where diamonds were found thousands of years ago. In the 1600’s, travelers from Europe brought back these。

How to be a successful language learner?―Learning a language is easy, even a child can do it!‖Most adults who are learning a second language would disagree with this statement. For them, learning a language is a very difficult task. They need hundreds of hours of study and practice, and even this will not guarantee success for every adult language learner.Language learning is different from other kinds of learning. Some people who are very intelligent and successful in their fields find it difficult to succeed in language learning. Conversely, some people who are successful language learners find it difficult to succeed in other fields.Language teachers often offer advice to language learners: “Read as much as you can in the new language.”“ Practice speaking the languageevery day. ”“Live with people who speak the language.”“Don‘t translate-try to think in the new language.”“ Learn as a child would learn;play with the language.”But what does a successful language learner do? Language learning research shows that successful language learners are similar in many ways.First of all, successful language learners are independent learners. They do not depend on the book or the teacher; they discover their own way to learn the language. Instead of waiting for the teacher to explain, they try to find the patterns and the rules for themselves. They are good guessers who look for clues and form their own conclusions. When they guess wrong, they guess again. They try to learn from their mistakes.Successful language learning is active learning. Therefore,successful learners do not wait for a chance to use the language; they look for such a chance. They find people who speak the language and they ask these people to correct them when they make a mistake. They will try anything to communicate. They are not afraid to repeat what they hear or1to say strange things; they are willing to make mistakes and try again. When communication is difficult, they can accept information that is inexact or incomplete. It is more important for them to learn tothink in the language than to know the meaning of every word.Finally, successful language learners are learners with a purpose. They want to learn the language because they are interested in the language and the people who speak it. It is necessary for them to learn the language in order to communicate with these people and to learn fromthem. They find it easy to practice using the language regularly because they want to learn with it.What kind of language learner are you? If you are a successful language learner, you have probably been learning independently,actively, and purposefully. On the other hand, if your language learning has been less than successful, you might do well to try some of the techniques outlined above.01-B. LanguageWhen we want to tell other people what we think, we can do it notonly with the help of words, but also in many other ways. For instance, we sometimes move our heads up and d own when we want to say "yes‖and we move our heads from side to side when we want to say "no." People who can neither hear nor speak (that is, deaf and dumb people) talk to each other with the help of their fingers. People who do not understand each other's language have to do the same. The following story shows how they sometimes do it.An Englishman who could not speak Italian was once traveling inItaly. One day he entered a restaurant and sat down at a table. When the waiter came, the Englishman opened his mouth, put his fingers in it,took them out again and moved his lips. In this way he meant to say, "Bring me something to eat." The waiter soon brought him a cup of tea. The Englishman shook his head and the waiter understood that he didn't want tea, so he took it away and brought him some coffee. The Englishman, who was very hungry by this time and not at all thirsty, looked very sad.He shook his head each time the waiter brought him something to drink.2The waiter brought him wine, then beer, then soda-water, but that wasn‘tfood, of course. He was just going to leave the restaurant when another traveler came in. When this man saw the waiter, he put his hands on his stomach. That was enough: in a few minutes there was a largeplate of macaroni and meat on the table before him.As you see, the primitive language of signs is not always very clear. The language of words is much more exact.Words consist of sounds, but there are many sounds which have ameaning and yet are not words. For example, we may say "Sh-sh-sh‖ when we mean "keep silent.‖ When babies laugh, we know they arehappy, and when they cry, we know they are ill or simply want something.It is the same with animals. When a dog says ―G-r-r‖ or a cat says "F-f-f‖ we know they are angry.But these sounds are not language. Language consists of words which we put together into sentences. But animals can not do this: a dog can say ―G-r-r‖ when he means "I am angry,‖ but he cannot say first "I‖ and then "am‖ and then "angry.‖ A parrot can talk like a man; it can repeat whole sentences and knows what they mean. We may say that aparrot talks, but cannot say that it really speaks, because it cannotform new sentences out of the words it knows. Only man has the power to do this.02-A. Taxes, Taxes, and More TaxesAmericans often say that there are only two things a person can be sure of in life: death and taxes, Americans do not have a corner on the "death" market, but many people feel that the United States leadsthe world with the worst taxes.Taxes consist of the money which people pay to support their government. There are generally three levels of government in the United States: federal, state, and city; therefore, there are three types of taxes.Salaried people who earn more than a few thousand dollars must pay3a certain percentage of their salaries to the federal government. The percentage varies from person to person. It depends on their salaries. The federal government has a graduated income tax, that is, the percentage of the tax (14 to 70 percent) increases as a person's income increases. With the high cost of taxes, people are not very happy on April 15, when the federal taxes are due.The second tax is for the state government: New York, California, North Dakota, or any of the other forty-seven states. Some states have an income tax similar to that of the federal government. Of course, the percentage for the state tax is lower. Other states have a sales tax, which is a percentage charged to any item which you buy in that state.For example, a person might want to buy a packet of cigarettes for twenty-five cents. If there is a sales tax of eight percent in that state, then the cost of the cigarettes is twenty-seven cents. Thisfigure includes the sales tax. Some states use income tax in addition to sales tax to raise their revenues. The state tax laws are diverse and confusing.The third tax is for the city. This tax comes in two forms: property tax (people who own a home have to pay taxes on it) and excise tax, which is charged on cars in a city. The cities use these funds for education, police and fire departments, public works and municipal buildings.Since Americans pay such high taxes, they often feel that they are working one day each week just to pay their taxes. People always complain about taxes. They often protest that the government uses their tax dollars in the wrong way. They say that it spends too much on useless and impractical programs. Although Americans have different views on many issues, they tend to agree on one subject: taxes are too high.02-B. AdvertisingAdvertising is only part of the total sales effort, but it is the part that attracts the most attention. This is natural enough because advertising is designed for just that purpose. In newspapers, in magazines, in the mail, on radio and television, we constantly see andhear the messages for hundreds of different products and services. For the most part, they arethe kinds of things that we can be persuaded to buy – food and drinks,4cars and television sets, furniture and clothing, travel and leisure time activities.The simplest kind of advertising is the classified ad. Every day the newspapers carry a few pages of these ads; in the large Sunday editions there may be several sections of them. A classified ad is usually only a few lines long. It is really a notice or announcement that something is available.Newspapers also carry a large amount of display advertising. Most of it is for stores or for various forms of entertainment. Newspapers generally reach an audience only in a limited area. To bring their message to a larger audience, many who want to put out their ads use nationalmagazines. Many of the techniques of modern advertising were developed in magazine ads. The use of bright colors, attractive pictures, and short messages is all characteristic of magazine ads. The most . The message itself is usually short, important purpose is to catch the eyeoften no more than a slogan which the public identifies with theproduct.The same techniques have been carried over into televisionadvertising. Voices and music have been added to color and pictures to catch the ear as well as the eye. Television ads are short –usually only15,30, or 60 seconds, but they are repeated over and over again so that the audience sees and hears them many times. Commercial television has mixed entertainment and advertising. If you want the entertainment, you have to put up with the advertising-and millions of people want the entertainment.The men and women in the sales department are responsible for the company‘s advertising, They must decide on the audience they want to reach. They must also decide on the best way to get their message to their particular audience. They also make an estimate of the costs before management approves the plan. In most large companies management is directly involved in planning the advertising.03-A. The Atlantic OceanThe Atlantic Ocean is one of the oceans that separate the Old World5from the New. For centuries it kept the Americas from being discoveredby the people of Europe.Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to "the edge ofthe world." Sailors were afraid that they might sail right off the earth. Another idea was that at the equator the ocean would be boiling hot.The Atlantic Ocean is only half as big as the Pacific, but it isstill very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2, 000 miles(3,200 km) wide. This narrowest place is between the bulge of south America and the bulge of Africa.Two things make the Atlantic Ocean rather unusual. For so large an ocean it has very few islands. Also, it is the world's saltiest ocean.There is so much water in the Atlantic that it is hard to imaginehow much there is. But suppose no more rain fell into it and no more water was brought to it by rivers. It would take the ocean about 4,000 years to dry up. On the average the water is a little more than twomiles (3.2 km) deep, but in places it is much deeper. The deepest spotis near Puerto Rico. This "deep" 30, 246 feet - almost six miles (9.6 km).One of the longest mountain ranges of the world rises the floor ofthe Atlantic. This mountain range runs north and south down the middleof the ocean. The tops of a few of the mountains reach up above the sea and make islands. The Azores are the tops of peaks in the mid-Atlantic mountain range.Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there islittle wind. In the days of sailing vessels the crew were afraid they would be becalmed here. Sometimes they were.Ocean currents are sometime called "rivers in the sea." One of these "river" in the Atlantic is called the Gulf Stream. It is a current of warm water. Another is the Labrador Current - cold water coming downfrom the Arctic. Ocean currents affect the climates of the lands near which they flow.The Atlantic furnishes much food for the people on its shores. Oneof its most famous fishing regions, the Grand Banks, is near6Newfoundland.Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships.We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it.A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!03-B. The MoonWe find that the moon is about 239,000 miles (384,551km) away fromthe earth, and, to within a few thousand miles, its distance always remains the same. Yet a very little observation shows that the moon is not standing still. Its distance from the earth remains the same, butits direction continually changes. We find that it is traveling in a circle - or very nearly a circle - round the earth, going completely round once a month, or, more exactly, once every 27 1/3 days. It is our nearest neighbour in space, and like ourselves it is kept tied to the earth by the earth's gravitational pull.Except for the sun, the moon looks the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2, 160 miles (3,389 km), or a little more than a quarter of the diameter of the earth.Once a month, or, more exactly, once every 29 1/2 days, at the time we call "full moon," its whole disc looks bright. At other times only part of it appears bright, and we always find that this is the partwhich faces towards the sun, while the part facing away from the sun appears dark. Artists could make their pictures better if they kept in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It merely reflects the light of the sun, like a huge mirror hung in the sky.Yet the dark part of the moon‘s surface is not absolutely black;7generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. we knows well how the surface of the sea or of snow, or even of a wet road, may reflect uncomfortably much of the sun's lighton to our faces. In the same way the surface of the whole earth reflects enough of the sun's light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark.If there were any inhabitants of the moon, they would see our earth reflecting the light of the sun, again like a huge mirror hung in the sky. They would speak of earthlight just as we speak of moonlight. "The oldmoon in the new moon's arms" is nothing but that part of the moon's surface on which it is night, lighted up by earth light. In the same way, the lunar inhabitants would occasionally see part of our earth in full sunlight, and the rest lighted only by moonlight; they might call this "the old earth in the new earth's arms.‖04-A. Improving Your MemoryPsychological research has focused on a number of basic principles that help memory: meaningfulness, organization, association, and visualization. It is useful to know how these principles work.Meaningfulness affects memory at all levels. Information that does not make any sense to you is difficult to remember. There are several ways in which we can make material more meaningful. Many people, for instance, learn a rhyme to help them remember. Do you know the rhyme―Thirty days has September, April, June, and November…? ‖ It helps many people remember which months of the year have 30 days.Organization also makes a difference in our ability to remember. How useful would a library be if the books were kept in random order?Material that is organized is better remembered than jumbled information. One example of organization is chunking. Chunking consists of grouping separate bits of information. For example, the number 4671363 is more easily remembered if it is chunked as 467,13,63. Categorizing is another means of organization. Suppose you are asked to remember the following8list of words: man, bench, dog, desk, woman, horse, child, cat, chair. Many people will group the words into similar categories and remember them as follows: man, woman, child; cat, dog, horse; bench, chair, desk. Needless to say, the second list can be remembered more easily than the first one.Association refers to taking the material we want to remember and relating it to something we remember accurately. In memorizing a number, you might try to associate it with familiar numbers or events. For example, the height of Mount Fuji in Japan - 12, 389 feet - might be remembered using the following associations: 12 is the number of months in the year, and 389 is the number of days in a year(365) added to the number of months twice (24).The last principle is visualization. Research has shown striking improvements in many types of memory tasks when people are asked to visualize the items to be remembered. In one study, subjects in onegroup were asked to learn some words using imagery, while the second group used repetition to learn the words. Those using imagery remembered 80 to 90 percent of the words, compared with 30 to 40 percent of thewords for those who memorized by repetition. Thus forming an integrated image with all the information placed in a single mental picture can help us to preserve a memory.04-B. Short-term MemoryThere are two kinds of memory: shore-term and long-term. Information in long-term memory can be recalled at a later time when it is needed. The information may be kept for days or weeks. Sometimes information in the long-term memory is hard to remember. Students taking exam often have this experience. In contrast, information in shore-term memory is kept for only a few seconds, usually by repeating the information over and over. For example, you look up a number in the telephone book, and before you dial, you repeat the number over and over. If someone interrupts you, you will probably forget the number. In laboratory studies, subjects are unable to remember three letters after eighteen seconds if they are not allowed to repeat the letters to9themselves.Psychologists study memory and learning with both animal and human subjects. The two experiments here show how short-term memory has been studied.Dr. Hunter studied short-term memory in rats. He used a special apparatus which had a cage for the rat and three doors, There was alight in each door. First the rat was placed in the closed cage. Next, one of the lights was turned on and then off. There was food for the ratonly at this door. After the light was turned off, the rat had to wait a short time before it was released from its cage. Then, if it went to the correct door, it was rewarded with the food that was there. Hunter did this experiment many times. He always turned on the lights in a random order. The rat had to wait different intervals before it was released from the cage. Hunter found that if the rat had to wait more than ten seconds, it could not remember the correct door. Hunter's results show that rats have a short-term memory of about ten seconds.Later, Dr. Henning studied how students who are learning English asa second language remember vocabulary. The subjects in his experiment were 75 students at the University of California in Los Angeles. They represented all levels of ability in English; beginning, intermediate, advanced, and native-speaking students.To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered. Each question had four choices. The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words thatsound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with thesame meaning. Some of them had four unrelated choices. For instance,weather, method, love, and result could be used as four unrelated words.Finally the subjects took a language proficiency test.Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning‘s results suggest that beginning students hold the10sound of words in their short-term memory, while advanced studentshold the meaning of words in their short-term memory.05-A. Fallacies about FoodMany primitive peoples believed that by eating an animal they couldget some of the good qualities of that animal for themselves. They thought, for example, that eating deer would make them run as fast asthe deer. Some savage tribes believed that eating enemies that had shown bravery in battle would make them brave. Man-eating may have started because people were eager to become as strong and brave as their enemies.Among civilized people it was once thought that ginger root by some magical power could improve the memory. Eggs were thought to make the voice pretty. Tomatoes also were believed to have magical powers. They were called love apples and were supposed to make people who ate themfall in love.Later another wrong idea about tomatoes grew up - the idea that they were poisonous. How surprised the people who thought tomatoes poisonouswould be if they could know that millions of pounds of tomatoes were supplied to soldiers overseas during World War II.Even today there are a great many wrong ideas about food. Some of them are very widespread.One such idea is that fish is the best brain food. Fish is good brain food just as it is good muscle food and skin food and bone food. But no one has been able to prove that fish is any better for the brain than manyother kinds of food.Another such idea is that you should not drink water with meals. Washing food down with water as a substitute for chewing is not a good idea, but some water with meals has been found to be helpful. It makes the digestive juices flow more freely and helps to digest the food.Many of the ideas which scientists tell us have no foundation have to11do with mixtures of foods. A few years ago the belief became general that orange juice and milk should never be drunk at the same meal. The reason given was that the acid in the orange juice would make the milk curdle and become indigestible. As a matter of fact, milk always meets in the stomach a digestive juice which curdles it; the curdling of the milk is the first step in its digestion. A similar wrong idea is that fish and ice cream when eaten at the same meal form a poisonous combination.Still another wrong idea about mixing foods is that proteins and carbohydrates should never be eaten at the same meal. Many people think of bread, for example, as a carbohydrate food. It is chiefly a carbohydrate food, but it also contains proteins. In the same way, milk, probably the best single food, contains both proteins and carbohydrates. It is just as foolish to say that one should never eat meat and potatoes together as it is to say that one should never eat bread or drink milk.05-B. Do Animals Think?The question has often been asked, Do animals think? I believe that some of them think a great deal. Many of them are like children in their sports. We notice this to be true very often with dogs and cats; but it is true with other animals as well.Some birds are very lively in their sports; and the same is truewith some insects. The ants, hardworking as they are, have their times for play. They run races; they wrestle; and sometimes they have mock fights together. Very busy must be their thoughts while engaged in these sports.There are many animals, however, that never play; their thoughts seem to be of the more sober kind. We never see frogs engaged in sport. They all the time appear to be very grave. The same is true of the owl, who always looks as if he were considering some important question.Animals think much while building their houses. The bird searchesfor what it can use in building its nest, and in doing this it thinks. Thebeavers think as they build their dams and their houses. They think in getting their materials, and also in arranging them, and inplastering them12together with mud. Some spiders build houses which could scarcely have been made except by some thinking creature.As animals think, they learn. Some learn more than others. Theparrot learns to talk, though in some other respects it is quite stupid. The mocking bird learns to imitate a great many different sounds. The horse is not long in learning many things connected with the work which he has to do. The shepherd dog does not know as much about most things as some other dogs , and yet he understands very well how to take care of sheep.Though animals think and learn, they do not make any real improvement in their ways of doing things, as men do. Each kind of bird has its own way of building a nest, and it is always the same way. And so of other animals. They have no new fashions, and learn none from each other. But men, as you know, are always finding new ways of building houses, and improved methods of doing almost all kinds of labor.Many of the things that animals know how to do they seem to know either without learning, or in some way which we cannot understand. They are said to do such things by instinct; but no one can tell whatinstinct is. It is by this instinct that birds build their nests and beavers their dam and huts. If these things were all planned and thoughtout just as men plan new houses. there would be some changes in the fashions of them, and some improvements.I have spoken of the building instinct of beavers. An English gentleman caught a young one and put him at first in a cage. After a while he let him out in a room where there was a great variety of things. As soon as he was let out he began to exercise his building instinct. He gathered together whatever he could find, brushes, baskets, boots, clothes, sticks, bits of coal, etc., and arranged them as if to build a dam. Now, if he had had his wits about him, he would have known that there was no use in building a dam where there was no water.It is plain that, while animals learn about things by their sensesas we do, they do not think nearly as much about what they learn, andthis is the reason why they do not improve more rapidly. Even the wisest of them, as the elephant and the dog, do not think very much about what they see and hear. Nor is this all. There are some thing that we understand,but about which animals know nothing. They have no knowledge of13anything that happens outside of their own observation. Their minds are so much unlike ours that they do not know the difference betweenrightand wrong.06-A. Diamonds。

Non-verbal CommunicationIf anyone asked you what were the main means of communication between people, what would you say? That isn’t a catch question. The answer is simple and obvious. It would almost certainly refer to means of communication that involve the use of words. Speakers and listeners-oral communication, and writers and readers-written communication. And you’d be quite right. There is, however, another form of communication which we all use most of the time, usually without knowing it. This is sometimes called body language. Its more technical name is non-verbal communication. Non-verbal, because it does not involve the use of words. NVC for short.When someone is saying something with which he agrees, the average European will smile and nod approval. On the other hand, if you disagree with what they are saying, you may frown and shake your head. In this way you signal your reactions, and communicate them to the speaker without saying a word. I referred a moment ago to "the average European”, because body language is very much tied to culture, and in order not to misunderstand, or not to be misunderstood, you must realize this.A smiling Chinese, for instance, may not be approving but somewhat embarrassed.Quite a lot of work is now being done on the subject of NVC, which is obviously important, for instance, to managers, who have to deal every day with their staff, and have to understand what other people are feeling if they are to create good workingconditions. Body language, or NVC signals, are sometimes categorized into five kinds: 1.body and facial gestures; 2.eye contact; 3.body contact or "proximity"; 4.clothing and physical appearance; and 5.the quality of speech. I expect you understood all those, except perhaps "proximity." This simply means "closeness". In some cultures-and I am sure this is a cultural feature and not an individual one-it is quite normal for people to stand close together, or to more or less thrust their face into yours when they are talking to you. In other cultures, this is disliked; Americans, for instance, talk about invasion of their space.Some signals are probably common to all of us. If a public speaker (like a professor, for example) is all the time fiddling with a pencil, or with his glasses, while he is talking to you, he is telling you quite clearly that he is nervous. A person who holds a hand over his mouth when he is talking is signaling that he is lacking in confidence. If you start wriggling in your chairs, looking secretly at your watches or yawning behind your hands, I shall soon get the message that I’m boring you. And so on. I'm sure you could make a whole list of such signals-and it might be fun if you did.All the signals I have mentioned so far can be controlled. If you are aware that you are doing these things, you can stop. You can even learn to give false signals. Most public speakers are in fact nervous, but a good speaker learns to hide this by giving off signals of confidence. Other kinds of NVC are not so easy to control. Eye contact, for instance. Unless you are confessing intense love, you hardly ever look into someone else’s eyes for ve ry long. If you try it, you’ll find they will soon away, probably in embarrassment.I’ve already mentioned proximity, so just a brief word now about our last two categories, which concern the way people dress and the way they speak. These are both pretty obvious signals. People may dress casually and speak casually, which signals that they are relaxed. Or they can dress formally and speak formally, showing their tenseness. In fact, non-verbal communication can, as the saying goes, speak volumes.【课文译文】非言语交际如果有人问你人与人之间最主要的交际手段是,你会怎么说?这倒不是一个难以回答的问题。

Unit 1第一部分 Text A【课文译文】怎样成为一名成功的语言学习者“学习一门语言很容易,即使小孩也能做得到。
”大多数正在学习第二语言的成年人会不同意这种说法。
对他们来说,学习一门语言是非常困难的事情。
他们需要数百小时的学习与练习,即使这样也不能保证每个成年语言学习者都能学好。
语言学习不同于其他学习。
许多人很聪明,在自己的领域很成功,但他们发现很难学好一门语言。
相反,一些人学习语言很成功,但却发现很难在其他领域有所成就。
语言教师常常向语言学习者提出建议:“要用新的语言尽量多阅读”,“每天练习说这种语言”,“与说这种语言的人住在一起”,“不要翻译——尽量用这种新的语言去思考”,“要像孩子学语言一样去学习新语言”,“放松地去学习语言。
”然而,成功的语言学习者是怎样做的呢?语言学习研究表明,成功的语言学习者在许多方面都有相似之处。
首先,成功的语言学习者独立学习。
他们不依赖书本和老师,而且能找到自己学习语言的方法。
他们不是等待老师来解释,而是自己尽力去找到语言的句式和规则。
他们寻找线索并由自己得出结论,从而做出正确的猜测。
如果猜错,他们就再猜一遍。
他们都努力从错误中学习。
成功的语言学习是一种主动的学习。
因此,成功的语言学习者不是坐等时机而是主动寻找机会来使用语言。
他们找到(说)这种语言的人进行练习,出错时请这些人纠正。
他们不失时机地进行交流,不怕重复所听到的话,也不怕说出离奇的话,他们不在乎出错,并乐于反复尝试。
当交流困难时,他们可以接受不确切或不完整的信息。
对他们来说,更重要的是学习用这种语言思考,而不是知道每个词的意思。
最后,成功的语言学习者学习目的明确。
他们想学习一门语言是因为他们对这门语言以及说这种语言的人感兴趣。
他们有必要学习这门语言去和那些人交流并向他们学习。
他们发现经常练习使用这种语言很容易,因为他们想利用这种语言来学习。
你是什么样的语言学习者?如果你是一位成功的语言学习者,那么你大概一直在独立地、主动地、目的明确地学习。
英语(一)、英语(二)——大学英语自学教程(上册)——电子版教材
大学英语自学教程(上)01-A. How to be a successful language learner?―Learning a language is easy, even a child can do it!‖Most adults who are learning a second language would disagree with this statement. For them, learning a language is a very difficult task. They need hundreds of hours of study and practice, and even this will not guarantee success for every adult language learner.Language learning is different from other kinds of learning. Some people who are very intelligent and successful in their fields find it difficult to succeed in language learning. Conversely, some people whoare successful language learners find it difficult to succeed in other fields.“Read as Language teachers often offer advice to language learners:much as you can in the new language.”“Practice speaking the language every day. ”“Live with people who speak the language.”“Don‘t translate-try to think in the new language.”“Learn as a child would learn; play with the language.”But what does a successful language learner do? Language learning research shows that successful language learners are similar in many ways.First of all, successful language learners are independent learners. They do not depend on the book or the teacher; they discover their ownway to learn the language. Instead of waiting for the teacher to explain,they try to find the patterns and the rules for themselves. They are good guessers who look for clues and form their own conclusions. When they guess wrong, they guess again. They try to learn from their mistakes.Successful language learning is active learning. Therefore, successful learners do not wait for a chance to use the language; they look for such a chance. They find people who speak the language and they ask these people to correct them when they make a mistake. They will try anything to communicate. They are not afraid to repeat what they hear orto say strange things; they are willing to make mistakes and try again.When communication is difficult, they can accept information that isinexact or incomplete. It is more important for them to learn to think inthe language than to know the meaning of every word.Finally, successful language learners are learners with a purpose.They want to learn the language because they are interested in thelanguage and the people who speak it. It is necessary for them to learn thelanguage in order to communicate with these people and to learn fromthem. They find it easy to practice using the language regularly becausethey want to learn with it.What kind of language learner are you? If you are a successfullanguage learner, you have probably been learning independently, actively,and purposefully. On the other hand, if your language learning has beenless than successful, you might do well to try some of the techniquesoutlined above.01-B. LanguageWhen we want to tell other people what we think, we can do it notonly with the help of words, but also in many other ways. For instance,we sometimes move our heads up and down when we want to say "yes‖ and we move our heads from side to side when we want to say "no."People who can neither hear nor speak (that is, deaf and dumb people)talk to each other with the help of their fingers. People who do notunderstand each other's language have to do the same. The followingstory shows how they sometimes do it.An Englishman who could not speak Italian was once traveling inItaly. One day he entered a restaurant and sat down at a table. When thewaiter came, the Englishman opened his mouth, put his fingers in it, tookthem out again and moved his lips. In this way he meant to say, "Bringme something to eat." The waiter soon brought him a cup of tea. TheEnglishman shook his head and the waiter understood that he didn't wanttea, so he took it away and brought him some coffee. The Englishman,who was very hungry by this time and not at all thirsty, looked very sad.He shook his head each time the waiter brought him something to drink.The waiter brought him wine, then beer, then soda-water, but that wasn‘t food, of course. He was just going to leave the restaurant when another traveler came in. When this man saw the waiter, he put his hands on his stomach. That was enough: in a few minutes there was a large plate of macaroni and meat on the table before him.As you see, the primitive language of signs is not always very clear.The language of words is much more exact.Words consist of sounds, but there are many sounds which have a meaning and yet are not words. For example, we may say "Sh-sh-sh‖ when we mean "keep silent.‖ When babies laugh, we know they are happy, and when they cry, we know they are ill or simply want something.It is the same with animals. When a dog says ―G-r-r‖ or a cat says"F-f-f‖ we know they are angry.But these sounds are not language. Language consists of wordswhich we put together into sentences. But animals can not do this: a dog -r-r‖ when he means "I am angry,‖ but he cannot say first "I can say ―GA parrot can talk like a man; it canand then "am‖ a nd then "angry.‖ repeat whole sentences a nd knows what they mean. We may say that aparrot talks, but cannot say that it really speaks, because it cannot formnew sentences out of the words it knows. Only man has the power to dothis.02-A. Taxes, Taxes, and More TaxesAmericans often say that there are only two things a person can besure of in life: death and taxes, Americans do not have a corner on the "death" market, but many people feel that the United States leads theworld with the worst taxes.Taxes consist of the money which people pay to support their government. There are generally three levels of government in the United States: federal, state, and city; therefore, there are three types of taxes.Salaried people who earn more than a few thousand dollars must paya certain percentage of their salaries to the federal government. The percentage varies from person to person. It depends on their salaries. The federal government has a graduated income tax, that is, the percentage of the tax (14 to 70 percent) increases as a person's income increases. With the high cost of taxes, people are not very happy on April 15, when the federal taxes are due.The second tax is for the state government: New York, California, North Dakota, or any of the other forty-seven states. Some states have an income tax similar to that of the federal government. Of course, the percentage for the state tax is lower. Other states have a sales tax, which is a percentage charged to any item which you buy in that state. For example, a person might want to buy a packet of cigarettes for twenty-five cents. If there is a sales tax of eight percent in that state, then the cost of the cigarettes is twenty-seven cents. This figure includes the sales tax. Some states use income tax in addition to sales tax to raise their revenues. The state tax laws are diverse and confusing.The third tax is for the city. This tax comes in two forms: propertytax (people who own a home have to pay taxes on it) and excise tax, which is charged on cars in a city. The cities use these funds for education, police and fire departments, public works and municipal buildings.Since Americans pay such high taxes, they often feel that they are working one day each week just to pay their taxes. People always complain about taxes. They often protest that the government uses their tax dollars in the wrong way. They say that it spends too much on useless and impractical programs. Although Americans have different views on many issues, they tend to agree on one subject: taxes are too high.02-B. AdvertisingAdvertising is only part of the total sales effort, but it is the part that attracts the most attention. This is natural enough because advertising is designed for just that purpose. In newspapers, in magazines, in the mail, on radio and television, we constantly see and hear the messages f or hundreds of different products and services. For the most part, they are the kinds of things that we can be persuaded to buy – food and drinks,cars and television sets, furniture and clothing, travel and leisure time activities.The simplest kind of advertising is the classified ad. Every day the newspapers carry a few pages of these ads; in the large Sunday editions there may be several sections of them. A classified ad is usually only afew lines long. It is really a notice or announcement t hat something is available.Newspapers also carry a large amount of display advertising. Mostof it is for stores or for various forms of entertainment. Newspapers generally reach an audience only in a limited area. To bring their message to a larger audience, many who want to put out their ads use national magazines. Many of the techniques of modern advertising were developed in magazine ads. The use of bright colors, attractive pictures, and short messages is all characteristic of magazine ads. The most important purpose is to catch the eye. The message itself is usually short, often no more than a slogan which the public identifies with the product.The same techniques have been carried over into television advertising. Voices and music have been added to color and pictures to catch the ear as well as the eye. Television ads are short –usually only 15,30, or 60 seconds, but they are repeated over and over again so that the audience sees and hears them many times. Commercial television has mixed entertainment and advertising. If you want the entertainment, you have to put up with the advertising-and millions of people want the entertainment.The men and women in the sales department are responsible for the company‘s advertising, They must decide on the audience they want to reach. They must also decide on the best way to get their message to their particular audience. They also make an estimate of the costs before management approves the plan. In most large companies management is directly involved in planning the advertising.03-A. The Atlantic OceanThe Atlantic Ocean is one of the oceans that separate the Old Worldfrom the New. For centuries it kept the Americas from being discoveredby the people of Europe.Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to "the edge of the world." Sailors were afraid that they might sail right off the earth. Another idea was that at the equator the ocean would be boiling hot.The Atlantic Ocean is only half as big as the Pacific, but it is stillvery large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2, 000 miles (3,200 km) wide. This narrowest place is between the bulge of south America and the bulge of Africa.Two things make the Atlantic Ocean rather unusual. For so large an ocean it has very few islands. Also, it is the world's saltiest ocean.There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into it and no more waterwas brought to it by rivers. It would take the ocean about 4,000 years todry up. On the average the water is a little more than two miles (3.2 km) deep, but in places it is much deeper. The deepest spot is near Puerto Rico. This "deep" 30, 246 feet - almost six miles (9.6 km).One of the longest mountain ranges of the world rises the floor ofthe Atlantic. This mountain range runs north and south down the middleof the ocean. The tops of a few of the mountains reach up above the sea and make islands. The Azores are the tops of peaks in the mid-Atlantic mountain range.Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels the crew were afraid they would be becalmed here. Sometimes they were.Ocean currents are sometime called "rivers in the sea." One of these "river" in the Atlantic is called the Gulf Stream. It is a current of warm water. Another is the Labrador Current - cold water coming down from the Arctic. Ocean currents affect the climates of the lands near which they flow.The Atlantic furnishes much food for the people on its shores. Oneof its most famous fishing regions, the Grand Banks, is nearNewfoundland.Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships.We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!03-B. The MoonWe find that the moon is about 239,000 miles (384,551km) away from the earth, and, to within a few thousand miles, its distance always remains the same. Yet a very little observation shows that the moon is not standing still. Its distance from the earth remains the same, but its direction continually changes. We find that it is traveling in a circle - or very nearly a circle - round the earth, going completely round once a month, or, more exactly, once every 27 1/3 days. It is our nearest neighbour in space, and like ourselves it is kept tied to the earth by the earth's gravitational pull.Except for the sun, the moon looks the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2, 160 miles (3,389 km), or a little more than a quarter of the diameter of the earth.Once a month, or, more exactly, once every 29 1/2 days, at the time we call "full moon," its whole disc looks bright. At other times only partof it appears bright, and we always find that this is the part which faces towards the sun, while the part facing away from the sun appears dark. Artists could make their pictures better if they kept in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It merely reflects the light of the sun, like a huge mirror hung in the sky.Yet the dark part of the moon‘s surface is not absolutely black;generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. we knows well how the surface of the sea or of snow, or even of a wet road, may reflect uncomfortably much of the sun's light on to our faces. In the same way the surface of the whole earth reflects enough of the sun's light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark.If there were any inhabitants of the moon, they would see our earth reflecting the light of the sun, again like a huge mirror hung in the sky. They would speak of earthlight just as we speak of moonlight. "The old moon in the new moon's arms" is nothing but that part of the moon's surface on which it is night, lighted up by earth light. In the same way, the lunar inhabitants would occasionally see part of our earth in full sunlight, and the rest lighted only by moonlight; they might call this "the old earth in the new earth's arms.‖04-A. Improving Your MemoryPsychological research has focused on a number of basic principles that help memory: meaningfulness, organization, association, and visualization. It is useful to know how these principles work.Meaningfulness affects memory at all levels. Information that does not make any sense to you is difficult to remember. There are several ways in which we can make material more meaningful. Many people, for instance, learn a rhyme to help them remember. Do you know the rhyme ―Thirty d ays has September, A pril, June, and November…? ‖ I t helps many people remember which months of the year have 30 days.Organization also makes a difference in our ability to remember. How useful would a library be if the books were kept in random order? Material that is organized is better remembered than jumbled information. One example of organization is chunking. Chunking consists of grouping separate bits of information. For example, the number 4671363 is more easily remembered if it is chunked as 467,13,63. Categorizing is another means of organization. Suppose you are asked to remember the followinglist of words: man, bench, dog, desk, woman, horse, child, cat, chair. Many people will group the words into similar categories and remember them as follows: man, woman, child; cat, dog, horse; bench, chair, desk. Needless to say, the second list can be remembered more easily than the first one.Association refers to taking the material we want to remember and relating it to something we remember accurately. In memorizing a number, you might try to associate it with familiar numbers or events. For example, the height of Mount Fuji in Japan - 12, 389 feet - might be remembered using the following associations: 12 is the number of months in the year, and 389 is the number of days in a year(365) added to the number of months twice (24).The last principle is visualization. Research has shown striking improvements in many types of memory tasks when people are asked to visualize the items to be remembered. In one study, subjects in one group were asked to learn some words using imagery, while the second group used repetition to learn the words. Those using imagery remembered 80to 90 percent of the words, compared with 30 to 40 percent of the words for those who memorized by repetition. Thus forming an integrated image with all the information placed in a single mental picture can helpus to preserve a memory.04-B. Short-term MemoryThere are two kinds of memory: shore-term and long-term. Information in long-term memory can be recalled at a later time when itis needed. T he information may be kept for days or weeks. Sometimes information in the long-term memory is hard to remember. Students taking exam often have this experience. In contrast, information in shore-term memory is kept for only a few seconds, usually by repeating the information over and over. For example, you look up a number in the telephone book, and before you dial, you repeat the number over and over. If someone interrupts you, you will probably forget the number. In laboratory studies, subjects are unable to remember three letters after eighteen seconds if they are not allowed to repeat the letters tothemselves.Psychologists study memory and learning with both animal and human subjects. The two experiments here show how short-term memory has been studied.Dr. Hunter studied short-term memory in rats. He used a special apparatus which had a cage for the rat and three doors, There was a light in each door. First the rat was placed in the closed cage. Next, one of the lights was turned on and then off. There was food for the rat only at this door. After the light was turned off, the rat had to wait a short time before it was released from its cage. Then, if it went to the correct door, it was rewarded with the food that was there. Hunter did this experiment many times. He always turned on the lights in a random order. The rat had to wait different intervals before it was released from the cage. Hunter found that if the rat had to wait more than ten seconds, it could not remember the correct door. Hunter's results show that rats have a short-term memory of about ten seconds.Later, Dr. Henning studied how students who are learning English as a second language remember vocabulary. The subjects in his experiment were 75 students at the University of California in Los Angeles. They represented all levels of ability in English; beginning, intermediate, advanced, and native-speaking students.To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered. Each question had four choices. The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words that sound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, a nd system w ould be four words with the same meaning. Some of them had four unrelated choices. For instance, weather, method, love, a nd result could be used as four unrelated words. Finally the subjects took a language proficiency test.Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have thedents hold the same meaning. Henning‘s results suggest that beginning stusound of words in their short-term memory, while advanced students hold the meaning of words in their short-term memory.05-A. Fallacies about FoodMany primitive peoples believed that by eating an animal they could get some of the good qualities of that animal for themselves. They thought, for example, that eating deer would make them run as fast as the deer. Some savage tribes believed that eating enemies that had shown bravery in battle would make them brave. Man-eating may have started because people were eager to become as strong and brave as their enemies.Among civilized people it was once thought that ginger root by some magical power could improve the memory. Eggs were thought to make the voice pretty. Tomatoes also were believed to have magical powers. They were called love apples and were supposed to make people who ate them fall in love.Later another wrong idea about tomatoes grew up - the idea that they were poisonous. How surprised the people who thought tomatoes poisonous would be if they could know that millions of pounds of tomatoes were supplied to soldiers overseas during World War II.Even today there are a great many wrong ideas about food. Some of them are very widespread.One such idea is that fish is the best brain food. Fish is good brain food just as it is good muscle food and skin food and bone food. But no one has been able to prove that fish is any better for the brain thanmany other kinds of food.Another such idea is that you should not drink water with meals. Washing food down with water as a substitute for chewing is not a good idea, but some water with meals has been found to be helpful. It makes the digestive juices flow more freely and helps to digest the food.Many of the ideas which scientists tell us have no foundation have todo with mixtures of foods. A few years ago the belief became general that orange juice and milk should never be drunk at the same meal. The reason given was that the acid in the orange juice would make the milk curdle and become indigestible. As a matter of fact, milk always meets in the stomach a digestive juice which curdles it; the curdling of the milk is the first step in its digestion. A similar wrong idea is that fish and ice cream when eaten at the same meal form a poisonous combination.Still another wrong idea about mixing foods is that proteins and carbohydrates should never be eaten at the same meal. Many people think of bread, for example, as a carbohydrate food. It is chiefly a carbohydrate food, but it also contains proteins. In the same way, milk, probably the best single food, contains both proteins and carbohydrates. I t is just as foolish to say that one should never eat meat and potatoes together as it is to say that one should never eat bread or drink milk.05-B. Do Animals Think?The question has often been asked, Do animals think? I believe that some of them think a great deal. Many of them are like children in their sports. We notice this to be true very often with dogs and cats; but it is true with other animals as well.Some birds are very lively in their sports; and the same is true with some insects. The ants, hardworking as they are, have their times for play. They run races; they wrestle; and sometimes they have mock fights together. Very busy must be their thoughts while engaged in these sports.There are many animals, however, that never play; their thoughts seem to be of the more sober kind. We never see frogs engaged in sport. They all the time appear to be very grave. The same is true of the owl, who always looks as if he were considering some important question.Animals think much while building their houses. The bird searchesfor what it can use in building its nest, and in doing this it thinks. The beavers think as they build their dams and their houses. They think in getting their materials, and also in arranging them, and in plastering themtogether with mud. Some spiders build houses which could scarcely have been made except by some thinking creature.As animals think, they learn. Some learn more than others. The parrot learns to talk, though in some other respects it is quite stupid. The mocking bird learns to imitate a great many different sounds. The horse is not long in learning many things connected with the work which he has to do. The shepherd dog does not know as much about most things as some other dogs , and yet he understands very well how to take care of sheep.Though animals think and learn, they do not make any real improvement in their ways of doing things, as men do. Each kind of bird has its own way of building a nest, and it is always the same way. Andso of other animals. They have no new fashions, and learn none from each other. But men, as you know, are always finding new ways of building houses, and improved methods of doing almost all kinds of labor.Many of the things that animals know how to do they seem to know either without learning, or in some way which we cannot understand. They are said to do such things by instinct; but no one can tell what instinct is. It is by this instinct that birds build their nests and beavers their dam and huts. If these things were all planned and thought out justas men plan new houses. there would be some changes in the fashions of them, and some improvements.I have spoken of the building instinct of beavers. An English gentleman caught a young one and put him at first in a cage. After a while he let him out in a room where there was a great variety of things. As soon as he was let out he began to exercise his building instinct. He gathered together whatever he could find, brushes, baskets, boots, clothes, sticks, bits of coal, etc., and arranged them as if to build a dam. Now, ifhe had had his wits about him, he would have known that there was nouse in building a dam where there was no water.It is plain that, while animals learn about things by their senses aswe do, they do not think nearly as much about what they learn, and this is the reason why they do not improve more rapidly. Even the wisest of them, as the elephant and the dog, do not think very much about what they see and hear. Nor is this all. There are some thing that we understand, but about which animals know nothing. They have no knowledge ofanything that happens outside of their own observation. Their minds areso much unlike ours that they do not know the difference between rightand wrong.06-A. DiamondsDiamonds are rare, beautiful, and also quite useful. They are thehardest substance found in nature. That means a diamond can cut anyother surface. And only another diamond can make a slight cut in adiamond.Diamonds are made from carbon. Carbon is found in all livingthings, both plant and animal. Much of the carbon in the earth comesfrom things that once lived.Scientists know that the combination of extreme heat and pressurechanges carbon into diamonds. Such heat and pressure exist only in thehot, liquid mass of molten rock deep inside the earth. It is thought thatmillions of years ago this liquid mass pushed upward through cracks inooled, the carbon changed into diamondthe earth‘s crust. As the liquid ccrystals.There are only four areas where very many diamonds have beenfound.The first known area was in India, where diamonds were foundthousands of years ago. In the 1600‘s, travelers from Europe brought back these beautiful stones from India. Diamonds became very popular withthe kings and queens of Europe.In the 1720‘s, diamonds were discovered in Brazil. This discoverycame at a good time, too. India‘s supply of diamonds was finallyrunningout after 2,500 years of mining the stones.In the 1800‘s, two other important areas were found in Russia andSouth Africa. Today, most diamonds used in industry come from Russia.Most diamonds used as gems come from South Africa. Only 25 percentof all diamonds mined are good enough for cutting into gems.Most of the diamonds in India were found in stream beds. Peoplewould pick up handfuls of gravel from the bottom of the streams and sort。

大学英语自学教程(上)01-A. How to be a successful language learner?“Learning a language is easy, even a child can do it!”Most adults who are learning a second language would disagree with this statement. For them, learning a language is a very difficult task. They need hundreds of hours of study and practice, and even this will not guarantee success for every adult language learner.Language learning is different from other kinds of learning. Some people who are very intelligent and successful in their fields find it difficult to succeed in language learning. Conversely, some people who are successful language learners find it difficult to succeed in other fields.Language teachers often offer advice to language learners: “Read as much as you can in the new language.”“ Practice speaking the language every day. ”“Live with people who speak the language.”“Don’t translate-try to think in the new language.”“ Learn as a child would learn; play with the language.”But what does a successful language learner do? Language learning research shows that successful language learners are similar in many ways.First of all, successful language learners are independent learners. They do not depend on the book or the teacher; they discover their own way to learn the language. Instead of waiting for the teacher to explain, they try to find the patterns and the rules for themselves. They are good guessers who look for clues and form their own conclusions. When they guess wrong, they guess again.They try to learn from their mistakes.Successful language learning is active learning. Therefore, successful learners do not wait for a chance to use the language; they look for such a chance. They find people who speak the language and they ask these people to correct them when they make a mistake. They will try anything to communicate. They are not afraid to repeat what they hear or to say strange things; they are willing to make mistakes and try again. When communication is difficult, they can accept information that is inexact or incomplete. It is more important for them to learn to think in the language than to know the meaning of every word.Finally, successful language learners are learners with a purpose. They want to learn the language because they are interested in the language and the people who speak it. It is necessary for them to learn the languagein order to communicate with these people and to learn from them. They find it easy to practice using the language regularly because they want to learn with it.What kind of language learner are you? If you are a successful language learner, you have probably been learning independently, actively, and purposefully. On the other hand, if your language learning has been less than successful, you might do well to try some of the techniques outlined above.01-B. LanguageWhen we want to tell other people what we think, we can do it not only with the help of words, but also in many other ways. For instance, we sometimes move our heads up and down when we want to say "yes” and we move our headsfrom side to side when we want to say "no." People who can neither hear nor speak (that is, deaf and dumb people) talk to each other with the help of their fingers. People who do not understand each other's language have to do the same. The following story shows how they sometimes do it.An Englishman who could not speak Italian was once traveling in Italy. One day he entered a restaurant and sat down at a table. When the waiter came, the Englishman opened his mouth, put his fingers in it, took them out again and moved his lips. In this way he meant to say, "Bring me something to eat." The waiter soon brought him a cup of tea. The Englishman shook his head and the waiter understood that he didn't want tea, so he took it away and brought him some coffee. The Englishman, who was very hungry by this time and not at all thirsty, looked very sad. He shook his head each time the waiter brought himsomething to drink. The waiter brought him wine, then beer, then soda-water, but that wasn’t food, of course. He was just going to leave the restaurant when another traveler came in. When this man saw the waiter, he put his hands on his stomach. That was enough: in a few minutes there was a large plate of macaroni and meat on the table before him.As you see, the primitive language of signs is not always very clear. The language of words is much more exact.Words consist of sounds, but there are many sounds which have a meaning and yet are not words. For example, we may say "Sh-sh-sh” when we mean "keep silent.” When babies laugh, we know they are happy, and when they cry, we know they are ill or simply want something.It is the same with animals. When a dog says “G-r-r”or a cat says "F-f-f” we know they are angry.But these sounds are not language. Language consists of words which we put together into sentences. But animals can not do this: a dog can say “G-r-r” when he means "I am angry,” but he cannot say first "I” and then "am” and then "angry.” A parrot can talk like a man; it can repeat whole sentences and knows what they mean. We may say that a parrot talks, but cannot say that it really speaks, because it cannot form new sentences out of the words it knows. Only man has the power to do this.02-A. Taxes, Taxes, and More Taxes Americans often say that there are only two things a person can be sure of in life: death and taxes, Americans do not have a corner on the "death" market, but many people feel that the United States leads the world with the worst taxes.Taxes consist of the money which people pay to support their government. There are generally three levels of government in the United States: federal, state, and city; therefore, there are three types of taxes.Salaried people who earn more than a few thousand dollars must pay a certain percentage of their salaries to the federal government. The percentage varies from person to person. It depends on their salaries. The federal government has a graduated income tax, that is, the percentage of the tax (14 to 70 percent) increases as a person's income increases. With the high cost of taxes, people are not very happy on April 15, when the federal taxes are due.The second tax is for the state government: New York, California, North Dakota, or any of the other forty-seven states. Some states have an income tax similar to that of。
